Moving power source device for heading machine

Abstract

The invention belongs to the technical field of mining equipment, and relates to a moving power source device for a heading machine. The moving power source device comprises a hydraulic oil tank, a variable plunger pump and a walking control handle. The hydraulic oil tank is connected with an inlet of the variable plunger pump. The variable plunger pump is started through a diesel engine. An outlet of the variable plunger pump is connected with an oil inlet P of a multi-way valve of the heading machine. A signal control oil port Ls of the multi-way valve is connected with a control port of the variable plunger pump. A first oil outlet T1 of the multi-way valve is connected with the hydraulic oil tank. A second oil outlet T2 of the multi-way valve is connected with the hydraulic oil tank. An oil inlet of the walking control handle is connected with a pressure reduction oil port of the multi-way valve, and an oil outlet of the walking control handle is connected with the first oil outlet T1. According to the moving power source device, power is generated through the oil pressure, and therefore the problem of explosions caused by on-off sparkles can be solved.

Description

technical field [0001] The invention relates to the technical field of mining equipment, in particular to a power source device capable of safely and continuously providing moving power for a roadheader. Background technique [0002] The roadheader is a machine used to excavate straight underground roadways. It is mainly composed of a traveling mechanism, a working mechanism, a loading mechanism and a reloading mechanism. Its working principle is: when the traveling mechanism is advancing, the cutting head in the working mechanism continuously breaks the rock and transports the broken rock away. Tunneling machine cost is big, structure is complicated, and loss is also bigger. [0003] When working underground in coal mines, roadheaders need to face many problems: [0004] 1. Due to the limitation of underground power resources, it is generally necessary to prepare a long section of cable. Usually, the roadheader needs to disassemble and assemble the cable every 200 meters,...

Problems solved by technology

[0004] 1. Due to the limitation of underground power resources, it is generally necessary to prepare a long section of cable. Usually, the roadheader needs to disassemble and assemble the cable every 200 meters, and the cable is often thick and laborious to transport;

[0005] 2. It is necessary to turn on and off the main power supply every time the cable is disassembled. Because of the explosive environment underground, the connection of the cable must be strictly controlled, otherwise the electric spark will cause an explosion, endangering the life safety of underground personnel. ;

[0006] 3. Because of safety issues, there will be strict procedures every time the power is turned on and off. It may even take nearly an hour to turn on and off the power every time. small view
