Hydraulic self-moving tail device

Abstract

The invention relates to a hydraulic self-moving tail device, which belongs to the technical field of transporters in mines. The hydraulic self-moving tail device comprises a head, a rail and a tail, wherein the head, the rail and the tail are connected in sequence from front to back; a belt of a belt conveyor is installed on the head, the rail and the tail; a track is arranged on the upper surface of the rail; a trolley which can slide back and forth and is connected with a head of a reversed loader together is arranged on the track; the left and right sides of the trolley are respectively and fixedly connected with one end of each pushing cylinder, and the other ends of the two pushing cylinders are respectively and fixedly connected with the left and right sides of the head; the pushing cylinders are connected with a hydraulic control system; and the contractility provided by the two pushing cylinders is greater than the friction force when the reversed loader is pulled forward and less than the friction force when the reversed loader is pushed backward. According to the hydraulic self-moving tail device disclosed by the invention, self movement is realized through mechanized operation and control, so that the tail of the belt conveyor is moved, manual operation is omitted, the work efficiency is high, and the use is safe and convenient.

Description

technical field [0001] The invention relates to a transport device in a mine, in particular to a hydraulic self-moving tail device. Background technique [0002] The belt conveyor connected to the loader on the coal mining face of the coal mine, as the loader advances, the tail of the belt conveyor will move accordingly. The existing mode of moving the tail of the belt conveyor is the mode of pulling with a return column winch. When in use, two sliders need to be set, and at least a winch operator, a hook worker, a signal worker, a security guard and a follower need to be equipped. There are following disadvantages in using this column back winch: [0003] 1. The belt conveyor needs to be pulled by the return column winch every day. It is necessary to repeat a series of tasks such as fixing the slider, unwinding the rope, connecting and fixing the hook head and the belt tail, and putting the warning operation. For a long time, the workload is virtually increased. increase...

Problems solved by technology

[0003] 1. The belt conveyor needs to be pulled by the return column winch every day. It is necessary to repeatedly perform a series of tasks such as fixing the slider, unwinding the rope, connecting and fixing the hook head and the belt tail, and releasing the warning operation. For a long time, the workload will be virtually increased. increase;

[0004] 2. The movement of the belt tail requires at least 5 people to operate, resulting in a lot of manual investment;

[0006] 4. Poor safety: (1) Using the return column winch for traction, the traction wire rope may be scratched to pull other objects, or due to broken wires, rust, or scratches, the traction force increases sharply, causing the wire rope to break. Injury accidents; (2) The driver of the return column winch is the farthest away from the tail of the belt machine, and the signal is transmitted through the whistle. It takes a certain time for the signal to be sent and received, and the clarity of the signal may lead to excessive traction of the tail , forming the phenomenon of reprinting the nose in the air

[0007] Due to the existence of the above defects, the work of belt tail movement in the fully mechanized mining face has been restricted, affecting the safety and work efficiency of the work.
