Problems solved by technology

[0003] Using electric or hydraulic drives, there are on-site working conditions. The development project is large, and power and cleaning units need to be added separately, which is expensive. In addition, the hydraulic unit has a high power failure rate, a large amount of maintenance, and a high cost of using working media, which needs to be replaced frequently.
Especially in the underground environment, there are space and explosion-proof restrictions. Using electric or hydraulic power is a great trouble and inconvenience for the underground working environment.
[0004] The single-action control of the equipment in each section of the inclined lane will inevitably lead to misoperation, and the phenomenon of opening and driving at the same time will not be able to effectively block the sports car that occurs during transportation.

Embodiment Construction

[0012] The present invention is described in detail below in conjunction with accompanying drawing:

[0013] figure 1 The middle pneumatic compound car arrester 1 is installed on the inclined alley at the parking lot 1.5m away from the slope change point, and the inclined alley pneumatic barrier 2 is installed on the inclined alley below the slope change point slightly longer than the length of a train (20m away from the slope change point).

[0014] When the vehicle arrives in front of the pneumatic compound car arrester 1, pull the handle on the interlocking pneumatic control box, the pneumatic compound car arrester 1 is opened, and the pneumatic car barrier 2 of the inclined lane is still closed; after the vehicle passes through the pneumatic compound car arrester 1 , pull the handle on the interlocking pneumatic control box again, the pneumatic compound car arrester 1 returns to the closed state, and the inclined alley pneumatic car barrier 2 is opened to drive.

Abstract

The invention discloses a car lug of a normally-closed inclined tunnel used for the safe transporting measure of the inclined tunnel of a coal mine, which comprises a normally-closed duplex car lug, a car lug bar of the normally-closed inclined tunnel, an interlocking pneumatic control box and a connection pipeline. The car lug has simple structure and is convenient to be maintained; interlocking control is adopted, therefore, devices are mutually closed and locked, thus being capable of preventing the running-way of the inclined tunnel reliably or stopping the running-way reliably and timely once the running-way happens; the original compressed air on the spot under a well is used as power, therefore, the car lug of the invention is safe and reliable, and the capital investment is reduced.

Description

technical field [0001] The invention relates to a car stop device used as a safety measure for coal mine inclined roadway transportation, in particular to a normally closed car stop device. Background technique [0002] At present, in the inclined lane transportation of mines, the safety measures for preventing sports cars or blocking the sports cars in time once a sports car occurs are generally adopted as electric motors or hydraulic drives, and single-action control is used between each device. [0003] The use of electric or hydraulic drives requires a large amount of development work due to on-site working conditions, and additional power and cleaning units need to be added, which is expensive, and the hydraulic unit has a high power failure rate, a large amount of maintenance, and a high cost of using working media, which needs to be replaced frequently. Especially there are space and explosion-proof restrictions in working in the underground environment. Using electri...
