Description

Technical Field

[0001] The utility model relates to the field of underground fully mechanized mining working face and chute mining and transportation in coal mines, in particular to a self-moving tail of a belt conveyor provided with a modular deviation adjustment mechanism. Background Art

[0002] The self-moving tail of the belt conveyor is the intermediate connection device between the bridge transfer machine and the belt conveyor of the chute transportation equipment. The long-stroke self-moving tail of the belt conveyor has been a development trend in recent years. At present, an ultra-long overlap system with a lap length of ≥30m between the self-moving tail of the belt conveyor and the transfer machine has been developed on the market, which makes the frequency of dismantling the belt frame and moving the self-moving tail as low as 1 time / day, achieving the goal of continuous automation advancement of "no dismantling and moving" in the daily production shift. The single long-stroke pulling and moving of the self-moving tail of the belt conveyor is composed of multiple small-stroke pulling and moving processes. During the multiple small-stroke pulling and moving processes, it is easy for the center line of the self-moving tail of the belt conveyor to deviate from the center line of the chute belt conveyor, causing problems such as coal leakage from the belt, increased belt wear, and belt breakage. Based on the principle of reducing the workload of manual processing and reducing the allocation of personnel underground, it is very important to develop a set of self-moving tail of the belt conveyor with mechanized deviation adjustment function. Summary of the invention

[0003] The utility model aims to provide a belt conveyor self-moving tail provided with a modular deviation adjustment mechanism, so that the self-moving tail of the belt conveyor with a large stroke can be adjusted to move forward straightly more conveniently and quickly.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A belt conveyor self-moving tail with a modular deviation adjustment mechanism, characterized in that it comprises a head end frame, a deviation adjustment mechanism, a base frame, and a tail end frame;

[0006] The deflection adjustment mechanism includes a connecting frame, a hydraulic cylinder seat, a regulating hydraulic cylinder, a pushing hydraulic cylinder, and a pushing seat;

[0007] The connecting frame, the hydraulic cylinder seat, the push hydraulic cylinder and the push seat are connected in sequence through pins, one end of the regulating hydraulic cylinder is connected to the connecting frame, and the other end is connected to the hydraulic cylinder seat;

[0008] When the hydraulic cylinder is fully extended, the hydraulic cylinder is perpendicular to the center line L of the tail of the belt conveyor.

[0009] When the regulating hydraulic cylinder is fully retracted, the push hydraulic cylinder is parallel to the center line L of the tail of the belt conveyor.

[0010] Furthermore, a group of deviation adjustment mechanisms are arranged on the left and right sides of the tail end frame of the belt conveyor self-moving machine, and a group of deviation adjustment mechanisms are arranged on the left and right sides of the tail end frame.

[0011] Furthermore, the deviation adjustment mechanism is connected with the head end frame and the tail end frame through bolts.

[0012] The beneficial effects of the utility model are mainly manifested in: the designed belt conveyor self-moving tail machine tail adjustment mechanism adopts modular design and bolt connection structure, which is relatively convenient to disassemble and assemble, and can be flexibly configured according to the actual needs of the chute and the length of the belt conveyor self-moving tail machine. Usually, the belt conveyor self-moving tail machine needs to have at least one set of adjustment mechanisms arranged on the left and right sides of the head and tail ends. If the matching belt conveyor self-moving tail machine is longer, one set of adjustment mechanisms can be arranged on the left and right sides of the middle base frame according to on-site needs to ensure the straightness of the belt conveyor self-moving tail machine; the set adjustment mechanism can flexibly adjust the angle of the push cylinder, and when the regulating hydraulic cylinder is fully extended, the push hydraulic cylinder is perpendicular to the center line of the belt conveyor self-moving tail machine, so that the adjustment force generated by the push hydraulic cylinder can reach the maximum; when the regulating hydraulic cylinder is fully retracted, the push hydraulic cylinder is parallel to the center line of the belt conveyor self-moving tail machine, saving the space occupied by the whole machine and not affecting the operation of other equipment in the chute.
