interlock

Abstract

The invention provides an interlocking device. The interlocking device comprises a fixing board, a limiting board, a first operating valve and a second operating valve; the first operating valve and the second operating valve are fixed to the fixing board; a first operating handle is arranged on the first operating valve and used for controlling starting or stopping of a first actuating mechanism; a second operating handle is arranged on the second operating valve and used for controlling starting or stopping of a second actuating mechanism; the limiting board is fixed to the first operating handle and used for limiting the second operating handle when the first operating handle is at a starting gear so that the second actuating mechanism can be in a stopping state; the limiting board is further used for limiting the first operating handle when the second operating handle is at a starting gear so that the first actuating mechanism can be in the stopping state. By means of the interlocking device, the first actuating mechanism and the second actuating mechanism can be prevented from simultaneously starting, meanwhile, extra parts are not required on an air path, and cost and space are effectively saved.

Description

technical field [0001] The invention relates to the technical field of mine transportation, in particular to an interlocking device. Background technique [0002] Inclined lanes, also known as inclined shafts, are currently the main form of transportation in coal mines. At present, the self-resetting operation valve of the ground stall in the inclined alley mostly adopts a two-position five-way valve, and the operating valve of the first pneumatic door stall at the upper entrance of the inclined alley mostly adopts a three-position four-way valve. These operating valves are centrally installed in the control room, and the hooker operates the operating valves by observing the transportation conditions in the inclined lane, so as to control the alternate opening of the ground and door stops. Due to the frequent hoisting times of the winch, the hooker is very prone to fatigue and misoperation occurs. During the operation, the ground and door stops are opened at the same time, ...

Problems solved by technology

[0004] However, the existing method of adding a one-way valve on the air path requires additional components such as rubber hoses and tees on the air path, which increases the cost and takes up a lot of space
