Field of the Invention

The invention relates to transportation system. More particularly, relates to the transportation of minerals in underground mines.

Background of the Invention

At present, common ground rail transportation device is adopted in each underground mine mostly in the conveyance driving surface crossheading of down-hole. The exploiting field drifting gallery uses accumulator loco motive big or small gradient tunnel, little counter-slope use mine lift winch, inner gear haulage gear and the endless rope winch of all size model drawing bunching and transport.

The patent CN201712625U discloses a transportation system used for an underground coal mine, which comprises an endless rope traction device and is characterized in that the transportation system also comprises a haulage vehicle. Brake tramcars are respectively arranged at the head part and the tail part of the haulage vehicle. The endless rope traction device sequentially tows the brake tramcar at the head part of the haulage vehicle and the brake tramcars and the haulage vehicle are equipped with rails. In the transportation system, the endless rope traction device of the underground coal mine is converted to a power take-off source of the transportation system, and system is equipped with the corresponding rails, so that the utility model solves problems that a mine car turns over, slides off or slides down without any limit in an inclined underground laneway.

But the present invention provides a solution to transport the minerals in underground mines where undulating roadways are present.
Brief Summary of the Invention

The following presents a simplified summary of the disclosure in order to provide a basic understanding to the reader. This summary is not an extensive overview of the disclosure and it does not identify key/critical elements of the invention or delineate the scope of the invention. Its sole purpose is to present some concepts disclosed herein in a simplified form as a prelude to the more detailed description that is presented later.

It is an object of the invention to transport the minerals in underground mines at undulating road ways present.

It is yet another object of the invention to operate two drums with the single motor consuming less power.

It is yet another object of the invention to create a high speed operation at undulating road ways.

According to an aspect of the present invention, the main and tail rope haulage system for transporting minerals is disclosed.

In accordance with the aspect of the present invention, It comprises two drums namely main and tail drum, two ropes namely main and tail rope, a single track, an electric motor and a pulley.

In accordance with the aspect of the present invention, the main drum is used to un coil the main rope by using the said electric motor and the tail drum is used to coil the tail rope gives additional movement to the tubs.

In accordance with the aspect of the present invention, the main drum is used to un coil the main rope by using the said electric motor and the tail drum is used to coil the tail rope gives additional movement to the tubs.

In accordance with the aspect of the present invention, the main and tail ropes are connected to the said two drums by installing a pulley.

Further objects, features, and advantages of the invention will be readily apparent from the following description of the preferred embodiments thereof, taken in conjunction with the accompanying drawings.

Brief Description of the Drawings

Although the characteristic features of this invention will be particularly pointed out in the claims, the invention itself and manner in which it may be made and used may be better understood after a review of the following description, taken in connection with the accompanying drawings wherein like numeral annotations are provided throughout.

Figure 1 illustrates the block diagram depicting the components of main and tail rope haulage system, according to the embodiment of the invention.

Figure 2 illustrates the flow chart depicting the flow of process of working of main and tail rope haulage system, according to the embodiment of the invention.

Detailed Description of the Invention

It is to be understood that the present disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the drawings. The present disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. In addition, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.

The use of “including”, “comprising” or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. The terms “a” and “an” herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. Further, the use of terms “first”, “second”, and “third”, and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another.

In accordance with an exemplary embodiment of the present invention, the main and tail rope haulage system comprises two drums namely main (104) and tail drum (102), two ropes namely main (118) and tail rope (116), a single track (108), an electric motor (106) and a pulley (112).

In accordance with an exemplary embodiment of the present invention, the main drum (104) is used to un coil the main rope (118) by using the said electric motor (106) and the tail drum (102) is used to coil the tail rope (116) gives additional movement to the tubs (110).

In accordance with an exemplary embodiment of the present invention, the main (104) and tail ropes (102) are connected to the said two drums (104,102) by installing a pulley (112).

Referring to the figures, Fig.1 illustrates the main and tail rope haulage system comprises of two drums namely main (104) and tail drum (102), two ropes namely main (118) and tail rope (116), a single track (108), an electric motor (106) and a pulley (112). The single track (108) is installed for transporting the tubs (110). The said two drums (102,104) are coiled with main rope (118) and tail rope (116) by connecting at pulley (112).

The main drum (104) uncoils the main rope (118) allowing the movement of tubs (110) and the tail drum (102) coils the tail rope (116) through sheave allowing the controlled movement of the rope haulage.

Fig.2 illustrates the flow of processes followed by providing the electrical supply to the motor (202) and the motor helps in revolution of the drums (204). The main rope is uncoiled through main drum and the tubs descents to certain level down through track (206). The tail rope is coiled through sheave to the tail drum allowing additional movement to the tubs (208).

It is therefore submitted that the instant invention has been shown and described in what is considered to be the most practical and preferred embodiments. It is recognized, however, that departures may be made within the scope of the invention and that obvious modifications will occur to a person skilled in the art. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
