Description

Pneumatic car arrester

Technical Field

The utility model relates to a stop car device that is used for colliery on the fixed track in pit, specifically speaking relate to a pnematic car arrester.

Background

The underground coal mine is transported by using a stepless rope winch, and the mine car runs on an underground fixed track under the traction of the stepless rope winch. Because the slope is great at the position of the variable slope of the upper flat plate, a car stopping device needs to be arranged on the fixed track. In the prior art, most of the car stopping devices are vertical car stopping levers arranged between fixed tracks at the slope changing points of an upper flat plate. When needs keep off the car, operating personnel place the fender car thick stick in digging the gallery of establishing in advance between the trapped orbit, the main problem that exists is: firstly, need operating personnel to operate between the trapped orbit, if the mine car has the swift current car phenomenon and will bring serious personal safety hidden danger for operating personnel, simultaneously, dig the tunnel of establishing in advance and set up the fender car thick stick temporarily, can appear sometimes keeping off the phenomenon that the car thick stick removed, roll-off gallery even, also can cause like this to keep off the car inefficacy.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to provide a pnematic car arrester that can effectively prevent the mine car swift current car, and can not bring personal safety hidden danger for operating personnel.

In order to solve the technical problem, the utility model relates to a pneumatic car arrester, which is provided with a car stopping lever and a horizontal rectangular mounting bottom plate, wherein the left side of the mounting bottom plate is fixedly provided with a first hinging seat, the first hinging seat is hinged with an air cylinder, a piston rod of the air cylinder is hinged with a second hinging seat, the bottom of the second hinging seat is fixedly provided with a rectangular sliding plate, and when the piston rod of the air cylinder makes telescopic motion, the rectangular sliding plate can slide left and right on the mounting bottom plate; the front hinged seat and the rear hinged seat are symmetrically and fixedly arranged on the mounting bottom plate between the air cylinder and the second hinged seat, the front hinged seat and the rear hinged seat are respectively provided with a front hinged shaft and a rear hinged shaft, the axes of the front hinged shaft and the rear hinged shaft are positioned on the same horizontal straight line, the number of the car blocking levers is two, the middle lower parts of the two car blocking levers are respectively arranged on the front hinged shaft and the rear hinged shaft on the front hinged seat and the rear hinged seat, the bottom ends of the two car blocking levers are respectively and fixedly arranged on sliding plates on the front side and the rear side of the second hinged seat, and when the sliding plates slide on the mounting bottom plate in the left and right directions, the two car blocking levers respectively rotate correspondingly by taking the corresponding front hinged.

Adopt the pnematic car arrester of above-mentioned structure, can be through controlling the flexible of blast gate remote control reservoir piston rod on the wind regime, and then can control the top of two fender car thick sticks and raise or descend, realize blockking the purpose that mine car and mine car pass through, the utility model discloses well operating personnel need not stand and keep off the car operation in the middle of the track, can not cause the personal safety hidden danger, simultaneously the utility model discloses a through two fender car thick sticks of reservoir control with preceding, back articulated shaft rotate as the axle and realize the rise and descend on fender car thick stick top, the reliability is high, can not produce swift current car phenomenon.
