[001] The embodiments herein generally relate to an apparatus for handling tubular members. More particularly to a handheld apparatus adapted to hold, lift, release and aid in transferring cylindrical objects or tubular members, such as pipes, storage drums, trumpet housing, thin-walled tubes and the like.
BACKGROUND
[002] Often in machine assembly line or plant, it is necessary to engage and lift tubular structures, such as pipes, tubing, trumpet housing and other equipment. As used herein, the term "tubular" will be used to refer to any and all tubular and/or generally cylindrical structures, such as lengths of pipe or tubing, lift subs, and like equipment. Such tubular members may have considerable mass and dimensions, and therefore be cumbersome to properly and safely grip and transport such structures. Most of the conventional cylindrical objects handling devices are either operated hydraulically or pneumatically. Further, they include a curved clamping jaws extending far enough to provide an adequate gripping span or surface, for which the objects to be handled must be substantially spaced apart to permit such gripping jaws to reach between them for selection of the object to be gripped and raised. Due to the size and weight of this type of tubular members, stability and balance of handling of these members are very important. For this reason, any minor misalignment between structure in the gripping apparatus for engaging the tubular member and the members could cause handling problems during lifting or other movement. Also, misalignment between the handling structure and the tubular member could cause loading problems. Furthermore, conventional gripping mechanisms for thin-walled cylindrical objects does not provide any safeguard against deforming and crushing the objects walls, since the clamping force applied
by these conventional mechanisms is not limited or reduced during their operating cycle.
[003] Therefore, there exists a need for a handheld apparatus adapted to hold, lift, release and aid in transferring tubular members that eliminates the aforementioned drawbacks.
OBJECTS
