DESC:FIELD OF INVENTION

The present invention relates to a device for lifting heavy components for automotive engines. In particular, the present invention relates to a tackle for lifting of engine crankcases. More particularly, the present invention relates to easy and safe handling of finished engine cylinder block and crankcases.

BACKGROUND OF THE INVENTION

An automobile manufacturing plant is a vast set-up fitted with different sub-units for manufacturing different components and subassemblies. Therefore, components/subassemblies manufactured in one units are required to be moved/transferred to other units and/or assembly and finishing lines for further processing.

The heavy components or subassemblies like cylinder blocks or crankcases are difficult to handle. The lifting of finished cylinder blocks or crankcases on ultrasonic dipping washing machine by using regular scissor type lifting tackle poses higher chances of loss of grip or locking of crankcase inside the washing machine. This is because, after dipping the engine block inside the washing liquid, it cannot be ascertained with surety whether the tackle is clamped with engine block or not.

Otherwise, any slippage of the engine block or case crank from the lifting tackle would pose serious safety issues and material damages to the part being lifted/lowered and/or handled, which may then need reworking, thereby would lead to increased cost and loss of valuable time.

Therefore, there is an existing need for facilitating a 180° rotation provision in the cylinder block lifting tackle which ensures a 100% positive clamping of engine block till the operator can confirm that it has reliably locked.

The locking mechanism should also be simple and user friendly to the lifting tackle operator.
PRIOR ART

DE 19712198 A1 discloses a horizontal length-adjustable support beam (5) which can be fixed in at least two positions by a radially pivoting stop device (10-14). The support elements (18,19) are installed on the telescopic beam to rotate around a vertical or horizontal axis and have adjustable support hooks (22,29,30). One support element (18) is rotatable by 360 degrees around a vertical axis by a cylinder and pin guide (20,21). The other support element swivels outwards around a pin (25) against the force of a spring (26).

US 3482817 A discloses a simple, one-piece device for lifting of massive parts, such as automotive engine blocks having upwardly projecting studs on to which an engine part, such as a carburetor, is removably attached. The device comprises an upright suspending plate member and a mounting plate member extending laterally from the bottom of the mounting plate member, preferably horizontally and equidistance from either side of the mounting plate member. These members are strongly welded to each others. The mounting plate member is formed to provide sets of holes, each set in a rectangular pattern, and the patterns being of different shapes, enabling the device to be mated downwardly at one set pattern on to studs of a correspondingly shaped rectangular pattern. The different pattern shapes permit use of the device for lifting engine blocks of different manufacture. The suspended plate member has an elongated horizontal opening, the upper limit of which is defined by depending formations, which subdivide the upper margin of the opening into, say, three downwardly facing recesses. These are selectively engageable by a hoist to enable a desirable balancing of the weight of the load for stability in transporting the latter from one place to another.

DISADVANTAGES WITH THE PRIOR ART

However, the problem with the conventional heavy tackles for lifting and handling heavy components have many disadvantages briefly discussed below:

• Rotation of parts is not possible.
• Components cannot be positively locked for preventing accidental slippage and damage to the components.

• Metal-to-metal contact causes rapid wear and tear of parts.

DETALED DESCRIPTION OF THE ACCOMPANYING DRAWINGS

Figure 1 shows a front view of a tackle 100 configured in accordance with the present invention for lifting and handling of heavy components, such as an engine cylinder block or crankcase and provided with facility for vertical rotation and positive clamping. It consists of a horizontal top bar assembly 110, a pair of plate assemblies 120 suspended on either side of the top bar assembly 110, a suspension pin 132 provided for insertion into the cam bore from the front and back side of the crankcase for acting as a positive locking means on either side of the top bar assembly 110. The pins 132 also facilitate 0 to 1800 rotation of heavy component loaded on this tackle 100. There are two different pivot points configured here, the first pivot point 132 is used for locking and the second pivot point 140 (Figure 5a) is used for rotation of the heavy component loaded and locked on the tackle 100. The cam-locking pins 132 can be made in two different sizes as per the cam bore diameter of the crankcase/engine block to be lifted/lowered and handled. In addition, a respective pin assembly 116 is provided to fit on either side of the top bar assembly 110. The pins 132 can be engaged with a respective spring locking mechanism on either inner side of the cam bore for locking the respective crankcase on the tackle100. For removing the crankcase, the pin 132 is pulled out by raising it up to the dead end by rotating in clockwise direction, thereby releasing it from the crankcase to be removed from the tackle 100. Another set of pins 152 are provided above pins 132, which engage in the oil gallery of the crankcase for locking the rotary motion around pin 152. Two projection locks are also provided for engaging the tackle in the cylinder block at 0° and 90° angles for easy engagement.

Figure 2a shows the front view of the horizontal top bar assembly 110 of the lifting tackle 100. It includes a hook point 112 for lifting and handling the engine cylinder blocks or crankcases. The slots 114 are provided with the pin assembly 116 for fitting into the top bar 110. The main horizontal top bar assembly 110 for lifting also has adjusting means for accommodating two different types of crankcases, i.e. for 4-cylinger and 6-cylinder crankcase. For this purpose, the hook point 112 should be offset from the center of the top bar assembly 110 for aligning with the axis of the center of gravity of the load, e.g. cylinder block or crankcase to be lifted/lowered and/or handled. This horizontal top bar assembly 110 also supports the pair of vertical plate assemblies 120 suspended at adjacent either end thereof.

Figure 2b shows the top view of the horizontal top bar assembly 110 of the lifting tackle 100 and having a plurality of slots, e.g. 2 slots 114 configured on the top bar for using the tackle to handle both 4-cylinder and 6-cylinder cylinder blocks. Therefore, the vertical plate assemblies 120 can be slid on the top bar 110 as per the requirement.

Figure 3 shows the front and side views of both vertical plates 120 provided on either side of the top bar assembly 110 for connecting it with the main pin assembly plate 138. A respective pivot pin 140 is the most critical pin in the tackle 100 to provide a connection between the vertical plate 120 attached to the top bar 110 and the pin 132 carrying the cam 134. It fits co-axially with the vertical plate 120 and cam 134. The pin 132 is constantly subjected to bending forces.

Figure 4a shows the pair of main assembly locking pins 132, 152 provided respectively for cam bore support and oil pump bore support on either side. These pins are spring loaded by means of a respective spring loading mechanism. Bushes 142 are provided as replaceable wearable parts and for facilitating the sliding motion. Positive locks are provided to hold the crank case between the center of tackle 100 for providing proper lifting / rotary motion. Main pin 132 is used to connect the vertical plate 120 with the main assembly plate 138, so that it can rotate w.r.t. to each other. Accordingly, 00 to 1800 locking is possible for easy catching of the cylinder block position. Soft material bushes 142 and 156 are provided at the main pin assembly for each locking pin 132 and placed on the exterior surface of the vertical plate 120. The bushes 142, 156, help in smooth motion of pins 132, 136 in and out of the vertical plate 120 and prevent a metal to metal contact, thereby decreasing wear and tear during lifting and handling operation.

Figure 4b shows the detailed profile of the cam 134. Two pins 160 at 0° and 163 at 90° angle are inserted therein to ensure that tackle 100 is at reference projection to engage properly in the crank case 200 to be lifted/lowered and/or handled.

Figure 5a shows a perspective side view of a tackle 100 for lifting and handling an engine cylinder block / crankcase to be held and locked between two vertical plate assemblies 120 thereof and provided with means for with vertical rotation and positive clamping. It includes a cam 134 pivoted at pivot point 140 disposed at the lower end of the vertical plate assembly 120 for facilitating 0 to 1800 rotation of the tackle 100.

Figure 7a shows another left-hand side view of the lifting and handling tackle 100 of Figure 5a loaded with an engine cylinder block / crankcase 200 tilted along the axis of its center of gravity suspending from the vertical plate assemblies 120 with its fire face FF at the bottom side.

Figure 7b shows another right-hand side view of the lifting and handling tackle 100 of Figure 5a loaded with an engine cylinder block / crankcase 200 tilted along the axis of its center of gravity suspending from the vertical plate assemblies 120 with its fire face FF at the bottom side.

DESCRIPTION OF THE INVENTION

Initially, the design of the center of gravity (C.G.) of the cylinder block / crankcase 200 is determined. Subsequently, the cylinder block / crankcase 200 is tilted along the axis of the center of gravity to help in minimizing the effort required by the operator therefor. Once the center of gravity is fixed, two support points to be provided for lifting the cylinder block / crankcase 200 are determined, which are normally the cam shaft bore and the oil pump bore.

The lifting tackle consists of a horizontal top bar assembly 110, on which a hook-point 112 is provided to lift an cylinder block / crankcase 200 suspended and locked between two vertical plate assemblies 120. Hook point 112 is offset from the center of top bar assembly 110 to align it with the axis of the center of gravity. Since tackle 100 is to be used for handling both 4-cylinder and 6-cylinder cylinder blocks simultaneously, a pair of slots 114 is provided on top bar 110 for sliding the vertical plate assemblies 120 on the top bar 110, as required. Slots 114 are also provided with a respective pin assembly 116, which fits into top bar 110. Each vertical plate assembly 120 is provided with a respective circular hollow pipe 122 at the top end thereof for sliding in the corresponding slots 114. A respective rib 124 is welded to vertical plate 120 for providing additional strength. Another main plate 138 for holding the support pins 132, 136 is attached to vertical plate 120 at the bottom end thereof. Both the plates 120, 138 are connected by a pin 136, which can make plates 120, 138 to swivel with respect to each other. In all, 4 pins or shaft (2 on either side) each are also provided for insertion into the cam bore and oil pump bore for supporting the load to be lifted/lowered and/or handled. The pins 132, 136 are spring loaded, which can be easily pulled in and out with the help of a T-handle provided to each pin. These pins are provided with notches on the exterior side for holding pins, when pulled out. This tackle 100 provides a rotation of 3600. Two positive locks are also provided 1800 apart.

WORKING OF THE INVENTION

Initially, both vertical plate assemblies 120 are arranged as per the lifting and handling requirement (4cyl., 6cyl.) and all the support pins are pulled out and a positive locking of the load to be lifted and/or handled is ensured. Then, hook point 112 is attached to the motor for raising/lowering or handling the tackle 100, which is placed such that the center of the support pins and cam bore match. Subsequently, the pins are released to fit into the cylinder block / crank case 200, which is then moved as required. Once this work is done, the cylinder block / crank case 200 is placed on the conveyor and the pins are pulled out and tackle 100 is taken away.

The lifting and handling tackle 100 described above is configured to be robust and having a load bearing capacity of 350 kilograms with 1.3 Factor of Safety (FoS). The weight of the cylinder block 200 to be lifted/lowered and/or handled is about 200 kg for a 6-cylinder engine block and about 150 kg for a 4-cylinder engine block.
