Abstract
The invention discloses an inclined roadway anti-sliding device which comprises a reaction device and a braking device and realizes braking and deceleration of underground sliding vehicles and sliding vehicles. The braking method and the effect of the anti-sliding device are as follows: when the mine car carries out cargo transportation according to fixed speed, the gravity pendulum bob is in a balanced state under the uniform motion state. When the mine car is accelerated and lifted, the gravity pendulum bob swings, but when the mine car is accelerated and runs within a control range, the magnetic gravity pendulum bob cannot swing to a large extent and cannot be attracted and contacted with the protrusion on the steel clamping rod. However, when the mine car slides and runs in the inclined roadway transportation process, the gravity pendulum bob under the mine car can swing greatly under the acceleration running state of the mine car, so that the pendulum bob can contact the clamping rod, the clamping rod is sucked down under the action of the gravity of the pendulum bob, the spring pops up, and the extension of the traction rope enables the brake block to contact with the wheel and the friction to force the mine car to stop. The invention can effectively control the car sliding and running accidents of the inclined drift mine car out of control of acceleration, decelerate the mine car in short time and short distance, and reduce unnecessary loss of personnel and property. The invention has simple operation and convenient installation and disassembly, can be used for different types of inclined drift mine cars, and is worthy of popularization.

Drawings
Fig. 1 is a schematic view of an inclined drift catcher.
Wherein: 1-wheels of the mine car; 2, braking quickly; 3-gravity pendulum bob; 4-a connecting rod; 5-clamping the rod; 6-a fixed pulley block; 7-the car body of the mine car; 8-spring and cassette; 9-steel wire hauling rope.
The specific embodiment is as follows:
in order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described in further detail below.
Example 1
A schematic diagram of the inclined drift catcher is shown in figure 1, and the inclined drift catcher comprises wheels 1 of a mine car, a brake block 2, a gravity pendulum bob 3, a bearing and connecting rod 4, a clamping rod 5, a fixed pulley block 6, a mine car body 7, a spring and clamping seat 8 and a steel wire traction rope 9.
Wherein: the operation method of the inclined roadway anti-sliding device comprises the following steps:
in a specific implementation, the bearing and the connecting rod 4 are first installed to the middle position of the two wheels 1. The spring and the clamping seat 8 form a 90-degree right angle with the connecting rod 4, and the gravity pendulum bob 3 is screwed on the connecting rod 4. The wire rope 9 is then connected at one end to the spring 8. The other end of the traction rope 9 is dyed to the front of the wheel 1 through the fixed pulley block 6 and connected with the brake block 2. The position of the brake block and the length of the traction rope 9 are adjusted to just contact and rub the wheel 1. The spring is then compressed, the clamping rod 5 fixes the spring, and the traction rope 9 lifts the brake block 2 through the conduction of the fixed pulley group 6. When the mine car 7 carries out cargo transportation according to a fixed speed, the gravity pendulum bob 3 is in a balanced state under the uniform motion state. When the mine car 7 is accelerated and lifted, the gravity pendulum 3 swings, but when the mine car is accelerated and operated within a control range, the magnetic gravity pendulum 3 does not swing to a large extent and does not come into attractive contact with the protrusion of the steel grab bar 5. However, when the tramcar 7 slides and runs in the inclined roadway transportation process, under the acceleration running state of the tramcar 7, the gravity pendulum 3 under the tramcar 7 can swing greatly, so that the pendulum 3 can contact the clamping rod 5 and suck the clamping rod 5 under the action of the gravity of the pendulum 3, the spring 8 pops out, and the traction rope 9 is prolonged to enable the brake block 2 to contact with the wheel 1 and rub to force the tramcar 7 to stop. Within the control range, when the running speed of the mine car 7 is high, the mass of the gravity pendulum 3 can be increased, so that the brake system of the mine car is kept within a high speed range. When the overall running speed of the mine car 7 is required to be slow, the mass of the gravity bob 3 is reduced. In a very small acceleration range, the gravity pendulum bob 3 can swing greatly, and the clamping rod 5 is pulled down to realize braking.
In summary, the embodiment of the present invention provides an inclined roadway anti-sliding device and an implementation method thereof, wherein the inclined roadway anti-sliding device is combined in a set of system for inclined roadway sliding and sliding.
