Abstract

The utility model relates to an automatic railway stop which is used for a mine. When a mine car is out of control on a slope to result in sliding down, the mine car which exceeds a normal speed drives a snake-shaped trigger to be connected with a power supply; an automatic coupling system starts, and a stop rod is pushed out a rail surface and comes into collision with the front shaft of the mine car. The stop rod drives a hook to bounce and hook the rear shaft of the mine car. The hook is connected with a brake mechanism by a steel cable to cause the mine car to park in definite distance. When the utility model stops the mine car, the utility model has the advantages of small impact force, undamaged device and safety.

Description

Automatic railway stop

The utility model is the safe Obstruct apparatus of using on a kind of mine, particularly a kind of automatic vehicle-blocking apparatus.

Used mine car on the mine has hawser to haul operation, and cable car can be controlled its running velocity, in case but hawser break, to cause derailing accident, especially on the mountain, ramp, be breakneck, car crash often, existing Obstruct apparatus generally adopts the rigidity interception, causes the equipment havoc.

Task of the present utility model is a kind of safe and reliable friction-type Obstruct apparatus of design, and its available steel rope tractive mine car out of control, and the speed of the mine car that little by little slows down is stopped mine car at last.

The utility model automatic vehicle-blocking apparatus mainly by snakelike binary pair, often start Cheng Kaiguan, electromagnet, pin, pin, hook, brake lever, wirerope, cylinder, friction band-type brake and constitute; When mine car out of control when causing derailing accident on broken road, snakelike binary pair swing can make above set angle often starts the journey switch closure, and the electromagnet energising promotes lever and exceeds rail level, bumps against with the mine car front axle, lever is toppled over, unplug the pin on the hook, hook is upspring by wind spring, hooks the mine car rear axle, when hook is being with wirerope to advance, cylinder drives friction brake sticking brake mechanism, and cylinder is held tightly gradually, and mine car is steadily stopped in certain distance.

The utility model has the advantages that impulsive force is little when holding up traffic, and equipment is not had destruction, can resume production at once owing to use friction braking, this stop device cost is low, and has very long service life, and maintenance is convenient.

Be described further below in conjunction with Figure of description:

Fig. 1 is the structural principle scheme drawing of automatic vehicle-blocking apparatus;

Number among the figure:

1, mine car rear axle

2, mine car body;

3, mine car front axle;

4, often start Cheng Kaiguan;

5, car body progressive position when rear axle contacts with arrester hook;

6, snakelike binary pair;

7, pendulum;

8, electromagnetic core;

9, electromagnetism pitch of the laps;

10, armature;

11, pin;

12, pin;

13, pin;

14, hook (pin hole is arranged);

15, wind spring;

16, hook is treated seat;

17, brake lever;

18, brake wirerope;

19, auxiliary cylinder;

20, cylinder;

21, pulley;

22, hook wirerope;

23, the friction strap of the brake.

In the accompanying drawing 1, in the multiple area of derailing accident, snakelike binary pair 6 is adorned in the track top, and its structure is made of the number joint, and there is the projection that can retrain mutually every joint upper end, there is pendulum 7 lower end, snakelike binary pair 6 has folk prescription to flexible, can only be rigidity to mine car 2 down directions to mine car 2 up direction bendings, when the pendulum 7 of snakelike binary pair 6 swings to set angle, can start and often start Cheng Kaiguan 4.Connect electromagnet (8,9), inhaling moving armature 10 rises, pin 11 is released rail level, bump against with mine car front axle 3, pin 11 is toppled over forward, dial-out is inserted in the pin 13 of restriction hook 14 positions on the hook 14, pin spring 12 can limit the position of pin 13, link up with 14 and upspring by wind spring 15 this moment, and hook 14 is suspended on the rear axle 1 of mine car 2, and hook treats that seat 16 is fixedly to treat to link up with usefulness, mine car was linked up with 14 and was caught on this moment, affect the hook wirerope 22 behind the hook to advance, hook wirerope 22 is entangled on the cylinder 20 by pulley 21, and hook wirerope 22 drives cylinders 20 and rotates, having driven brake wirerope 18 simultaneously twines on auxiliary cylinder 19, brake wirerope 18 drives the brake lever and the friction strap of the brake 23 rotates round about, makes the friction strap of the brake 23 hold cylinder gradually tightly, and hook wirerope 22 holds mine car 2 and stops reposefully gradually.

Claims

1, the automatic vehicle-blocking apparatus used of a kind of mine is characterized in that mainly by snakelike binary pair, often starting Cheng Kaiguan, electromagnet, lever, pin, hook, brake linkage, wirerope, cylinder, friction band-type brake and constitutes; Out of control when mine car speed, during overrate, snakelike binary pair swing surpasses set angle, can make and often start the journey switch closure, the electromagnet energising promotes lever from going out rail level, bump against with the mine car front axle, pin is toppled over, and pushes the pin on the hook aside, and hook is upspring by wind spring, hook the mine car rear axle, when hook had been with wirerope to advance, cylinder drove friction brake sticking brake mechanism cylinder is held tightly gradually, and mine car is stopped.
