Detailed Description

As shown in fig. 1-3, an embodiment of a track stopper includes a shaft 3 rotatably mounted below the track, and the shaft is installed in a pit formed below the track by hardening the track while the track is on the ground. Install on the pivot 3 and hinder car spare 4, make and hinder car spare and pivot synchronous revolution, hinder and seted up two slide openings 5 on the car spare 4, two slide bar 6 is installed all slidable in the slide opening 5, two slide bar 6 all rotationally installs rotating turret 7 towards the end of mine car one side. All the sleeves are provided with springs 8 on the two sliding rods 6, the springs 8 provide elasticity towards the direction of the mine car for the sliding rods 6, specifically, a spring limiting block 16 is arranged near one end of each sliding rod 6, the springs are arranged on the sliding rods in a penetrating mode, one ends, far away from the spring limiting blocks, of the sliding rods penetrate into sliding holes from one side of the mine car, nuts 17 are installed, one ends of the springs 8 abut against the spring limiting blocks 16, the other ends of the springs abut against the car blocking pieces 4, and the springs can provide elasticity towards the direction of the mine car for the rotating frame. The rotating frame 7 is provided with three branches 9, the branches 9 of the two rotating frames 7 correspond to each other one by one, and rotating rollers 10 are arranged between the corresponding branches 9.

The cage position detection device is characterized by further comprising an inductor 1 used for sensing the position of the cage, wherein the inductor 1 is electrically connected with an electromagnet 2, the inductor is placed at the mine outlet, when the cage moves upwards to the mine outlet (above the ground), the inductor can sense the cage position, and then an electric signal is sent to the electromagnet to enable the electromagnet to be electrified. The sensor may also send an electrical signal to the controller, which then controls the electromagnet to be energized.

A bracket 11 is fixed on one side of the track, and the electromagnet 2 is installed on the bracket 11. The bracket 11 is slidably mounted with an iron block 12 that can be attracted by the electromagnet 2, and specifically, the iron block is mounted below the electromagnet via a plastic frame so that the iron block can move up and down along the frame, and the iron block moves up when the electromagnet is energized. And a traction wire 13 is connected below the iron block 12, and the traction wire 13 is a chain. The lower end of the traction wire 13 is connected to one end of a rocker arm 14, and the other end of the rocker arm 14 is installed on the rotating shaft 3, so that the rocker arm can drive the rotating shaft to rotate.

The rocker arm 14 is provided with a counterweight 15 at one end far away from the rotating shaft 3, when the cage does not reach a mine exit (above the ground), the rocker arm is in a horizontal state under the action of the counterweight, so that the car stopping piece is vertical, when the mine car reaches the position, the mine car is stopped by the car stopping piece, the spring is extruded at the same time, and the restoring force of the spring enables the mine car to move backwards for a certain distance. When the cage reaches a mine outlet (above the ground), the electromagnet is electrified, the iron block moves upwards to enable the rocker arm to swing upwards, the car stopping piece overturns towards the direction of the mine car, and the rotating roller arranged on the car stopping piece can prevent the car stopping piece from being clamped by the mine car when overturning. After the car blocking piece is turned towards the direction of the mine car, the height of the car blocking piece is reduced, and the mine car can pass through. When the cage is moved downwards, the electromagnet is powered off, and the car stopping piece returns to be vertical under the action of the gravity of the rocker arm, so that the condition that a mine car enters a mine outlet when the cage does not reach the mine outlet (above the ground) and danger is caused is avoided.
