Self-moving tail push unit for belt conveyor

Abstract

A self-moving tail push unit for a belt conveyor comprises loader head fixed seats, push rails and conveyor tail fixed seats. The self-moving tail push unit for the belt conveyor is characterized in that the push rails are fixedly connected to the conveyor tail fixed seats, unidirectional brake blocks are arranged and welded on the push rails, vertical boards of the loader head fixed seats are provided with connecting holes connected with a headstock of a loader, the bottom of each loader head fixed seat is connected with the upper end of a piston of a support cylinder through a pin, one end of each push cylinder is hinged to the bottom of the corresponding loader head fixed seat through a pin, one end of the piston of each push cylinder is hinged with a push block through a pin, and each push block is hinged to an ejector block through a pin. The self-moving tail push unit for the belt conveyor has the advantages that pushing force is high, labor is saved, labor intensity is reduced, operation is simple, mechanical level of coal mine is increased, failure rate is low, maintenance is convenient, and safety is high.

Description

technical field [0001] The invention belongs to coal mine machinery, in particular to a self-moving belt machine tail pushing 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 must move accordingly. In the past, the tail of the belt conveyor was moved by a slow winch. [0003] In general, the length of the reloading machine is 32 meters, the length of the tail of the belt conveyor is 12 meters, the maximum distance between the pump box of the string car and the head of the reloading machine is 60 meters, the length of the string car is 45 meters, and the distance between the slow winch and the string The distance between cars is 10 meters. Generally, it is day shift maintenance, second shift and night shift production, the cutting depth of the shearer drum is generally 800mm, the total footage of the second shift and night shift is about 8 meters, an...

AI Technical Summary

Problems solved by technology

The tail of the belt machine needs to be pulled by a slow-speed 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 releasing the warning operation. very big

[0007] 2. Much labor input

At least 5 people are needed to move the tail of the belt conveyor. The current situation in the mine is that there are few personnel and heavy workload. The number of people involved in this work seems to be relatively large.

[0008] 3. The working area is relatively long

The maximum distance from the winch to the reloading head of the transport plane is 115 meters. In this laneway area, it is required to put on a guard, and cross operations are not allowed in this area, and pedestrians are not allowed in this area, which will cause inconvenience to other related work.

[0009] 4. Relatively poor security

A. Use a slow winch for traction. The traction wire rope may be scratched to pull other objects, or may be broken due to broken wires, rust, or scratches. The traction force increases sharply, causing the wire rope to break; B. The distance between the winch operator and the driver The tail of the belt machine is the farthest, and the signal is transmitted through the whistle, because it takes a certain time to send out and receive the signal, and whether the signal is clear or not may lead to excessive traction of the tail, resulting in the phenomenon that the head of the reloading machine is suspended

[0010] 5. Larger traction force

[0011] Due to the above factors, the work of belt tail movement in the fully mechanized mining face has been restricted, affecting the safety and work efficiency of the work.
