Problems solved by technology

[0003] The function of the car stop device in the tank is that when the mine car enters the cage, the car stop device locks to stabilize or fix the mine car. The tank block is the most traditional bicycle cage. A commonly used car stop device, but its operation is cumbersome, and it is prone to injury accidents such as squeezing hands and feet during use
With the improvement of automation awareness, various domestic cage manufacturers and coal mine manufacturers have developed many forms of automatic or semi-automatic tank car stop devices, and the opening and closing of the devices are driven by manual, electric, hydraulic, or pneumatic drives. The operation accounts for a large proportion, and the automatic realization is mostly realized by the mechanism linked with the swinging track of the cradle. A considerable part of this type of device is eventually abandoned due to its relatively complicated structure and inconvenient maintenance in practical use. This is the current situation. real problems

Embodiment 1

[0020] Example 1: see Figure 1-6 , a vehicle blocking device in a tank, including a fixed vehicle block 3 fixed on the inner bottom track of the cage and a self-locking safety device, the bottom surface track of the cage is two parallel laid track rails, and the fixed vehicle blocks are symmetrically distributed On two parallel rails, the fixed block on the same side rail includes a front fixed block and a rear fixed block, both of which are hinged on the track through the fixed block bolt 4 , the positions of the front fixed block and the rear fixed block on the track match the positions of the two wheels on the same side of the vehicle. When the front fixed block springs up to block the front wheel, the rear fixed block is pressed by the rear wheel. The lower parts of the front and rear fixed blocks are connected with fixed block pull rods or steel wire ropes 6, and the front fixed block and the rear fixed block are hinged on the rail side wall through fixed block bolts 4,...

Embodiment 2

[0023] Example 2: see Figure 7 , is basically the same as Embodiment 1, and the similarities are not repeated, and the difference is that: the outer side of the front fixed block and / or the track on the outer side of the rear fixed block is provided with a wheel limiter 24, and the limiter It is a steel plate structure welded on the upper end surface of the rail, which is actually a structure protruding from the rail surface. The setting of the vehicle stop block 24 makes the mine car 2 stop due to the possible elastic recovery force of the fixed block when it enters the cage and is fixed. The car channeling phenomenon that produces can be contained.

Abstract

Disclosed is a tramcar-blocking device inside a cage. The tramcar-blocking device inside the cage comprises a front shield baffle plate, a sealing window, a sealing baffle plate, an observation window and an observation window baffle plate. Both the sealing baffle plate and the observation window baffle plate are movably hinged with the front shield baffle plate. The sealing device further comprises an air pressure-maintaining system and a bentonite system. A compressed-air-filling opening is connected and fixed on the front shield baffle plate. A bentonite-filling opening is connected on the front shield baffle plate and a conveying opening of a spiral conveying machine of a shield machine. Compressed air and bentonite can be filled in a tunnel face through the air pressure-maintaining system and the bentonite system. Front end soil pressure is maintained to be balanced through an automatic pressure-maintaining device, and accordingly stability of the tunnel face can be guaranteed and ground surface settlement can be effectively controlled, safe operations of the shield machine are greatly guaranteed, and therefore production efficiency is improved and operation risk is reduced.

Description

technical field [0001] The invention relates to a vehicle blocking device for a mine cage, in particular to a vehicle blocking device inside a tank. Background technique [0002] The cage is a container for lifting personnel or materials in mines (it is mostly used for auxiliary shaft lifting in coal mine enterprises), and is an important pivotal equipment for the lifting system. And the cage car blocking device is an important device for fixing mine cars in the cage. [0003] The function of the car stop device in the tank is to lock the car stop to stabilize or fix the car when the mine car enters the cage. The tank block is the most commonly used car stop device in the traditional bicycle cage, but its operation is heavy and difficult Injury accidents such as squeezing hands and feet are prone to occur during use. With the improvement of automation awareness, various domestic cage manufacturers and coal mine manufacturers have developed many forms of automatic or semi...
