Turnout rotary charge-control electric cabinet for mine

Abstract

The invention discloses a turnout rotary charge-control electric cabinet for a mine. The turnout rotary charge-control electric cabinet comprises a cabinet body and a circuit control module which is used for controlling turnout rotary reversing. The circuit control module comprises a data acquisition module, a data processing module and a hydraulic driving module. The data acquisition module comprises a pressure detection unit, a first position detection unit and a second position detection unit. The hydraulic driving module comprises a hydraulic performing mechanism, a hydraulic control mechanism and a hydraulic power mechanism. The cabinet body is an anti-explosion cabinet body and comprises an upper cabinet body, a lower cabinet body and a rack. The rack is a sleigh type rack. The upper cabinet body is provided with a first wiring port and a second wiring port. The turnout rotary charge-control electric cabinet is simple in structure and reasonable in design, and complexity of manual operation is avoided, accurate reversing is ensured, the transport efficiency is improved, and serious safety accidents caused by not-in-place manual operation, misoperation and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of coal mine underground transportation equipment, and in particular relates to an electric control box for mine turnout rotation control. Background technique [0002] In mine transportation, mine track is an important facility for transportation and is indispensable in mine production. The underground track is changeable and complex, and there are often many forks. The turnout is a device to ensure the safe transfer of rolling stock, and is used to connect the first fork or the second fork. The control mode of the switch is manual, electric and pneumatic, and the switch is controlled to rotate and steer to connect with the first branch or the second branch. In recent years, with the continuous advancement of modern science and technology, the unit transportation volume of coal mining equipment has become larger and larger, especially under the conditions of high gas, large inclination, long distance and h...

Problems solved by technology

But its hydraulic control system is simple and crude, and when the locomotive in the coal mine roadway is running, when changing the track of the locomotive, it generally adopts a purely manual operation method. Every time, the locomotive needs to be stopped in front of the turnout, and it can only pass after manual reversing. Especially when going up and downhill, this method is very dangerous, and it is also extremely uncoordinated with modern mine construction

However, there are explosive gases such as coal dust and methane underground in coal mines. If it is still manually operated on site, it will not only waste manpower, but also pose a safety hazard, and cause harm to the operator's body. It will also waste roadway transportation time, reduce mine transportation capacity, and work efficiency. Low

At present, there is no electric control equipment for mining turnouts with hydraulic reversing, only a simple pneumatic control electric control box, and the control principles of the two are different, so they cannot be used at all.

Nowadays, there is a lack of a mine turnout rotary control electric control box with simple structure, low cost, reasonable design, and easy control. The data acquisition module controls the hydraulic drive module to drive the turnout, eliminating the complicated manual operation and ensuring The reversing is accurate, which improves the transportation efficiency and avoids serious safety accidents caused by improper manual operation and misoperation.
