Description

Technical Field

[0001] The utility model relates to the field of mining devices, in particular to a track car blocker in a cage. Background Art

[0002] The cage hoisting method is currently the most commonly used hoisting solution in mines. Especially in heavy-load hoisting transportation, the mine car needs to be fixed in the tank, otherwise it is easy to cause the hoisting cage to tilt. In addition, due to the strength and structural limitations of the tank door, it is very easy to induce the mine car to fall out of the tank. In some small private mines, usually during special loading, people and cars share the tank, and manual support is used to stabilize the car, which is more dangerous. For the hoisting container of the wire rope tankway, the center of gravity of the hoisting container may also be skewed, causing the tankway rope to shake and tremble during the hoisting process, aggravating the wear of the tankway structure and increasing the daily maintenance cost. Therefore, during the hoisting process, a tank car blocker must be used to limit the mine car in the tank.

[0003] At present, most mines use check claw type and blocking claw type tank car stoppers. When the tank cage reaches the loading position, operators are required to enter the tank to operate the tank car stopper. This process is not only dangerous and inefficient, but also easily hinders the overall production efficiency of the mine. Utility Model Content

In this way, the first docking seat 56 can be put into a rotating state through the first docking seat 56, and the car blocking block 57 connected to the front side of the swing arm 55 can be rotated, and the car blocking block 57 can be swung by the swing arm 55 to realize convenient rising or falling of the front side, so as to realize efficient axle blocking.

[0031] The swing arm 55 is gradually bent upward from back to front, and the front counterweight of the swing arm 55 is greater than the rear counterweight, to ensure that when the pressure head 53 is away from the pressure head 53, the front side of the swing arm 55 can automatically move downward in accordance with its own weight to achieve the rapid formation of the axle blocking state; the middle part of the lower end of the vehicle blocking block 57 is rotatably docked with the inside of the second docking seat 58, and the front and rear sides of the vehicle blocking block 57 are both bent upward, so that the vehicle blocking block 57 as a whole can be used to achieve stable axle blocking.

[0032] Here’s how it works:

[0033] When the cage track blocker is to be used, the first car stop assembly 4 and the second car stop assembly 5 can be installed inside the lower end of the cage compartment 1 respectively. When the mine car is pushed by machinery or manpower to cooperate with the combined guiding effect of the guide rails 2 and the limit plates 3 on both sides of the lower end of the cage compartment 1 to achieve smooth movement, the wheels on both sides of the bottom of the mine car will be connected with the baffles 446 of the elastic blocking structure 44 set inside the first car stop assembly 4, so that the baffles 446 on both sides are squeezed by the wheels and rotate outward at the same time. In this way, the rotating seat 445 connected to the lower end of the baffle 446 will cooperate with the connecting shaft 441 connected in the middle to realize the inward rotation activity, and through the rotation of the rotating seat 445, the connecting arm 435 connected to the lower end of the rotating seat 445 can realize the inward push activity to drive the turntable 434 connected at the other end, so that the turntable 434 can realize clockwise rotation as a whole. When the turntable 434 rotates clockwise, the rotating shaft 431 connected in the middle will cooperate with the connecting shaft 431 to realize the synchronous driving of the connecting plate 432 connected to the front side, so that the counterweight 433 connected to the front end of the left side of the connecting plate 432 is lifted in advance. When the wheels on both sides pass through the baffle 446, the squeezing effect on the baffles 446 on both sides will be released. In this way, the counterweight 433 in the lifted state will automatically move down to cooperate with the connecting plate 432 to realize the counterclockwise rotation of the rotating shaft 431. As a result, the turntable 434 can be synchronously driven to push the connecting arm 435 connected at the upper and lower ends outward, so that the connecting arm 435 pushes the rotating seat 445 outward, and the baffle 446 arranged on the top of the rotating seat 445 is quickly reset. In this way, the baffle 446 can be reset to the vertical state again to block the rear wheels of the mine car and prevent the mine car from moving backward by itself, thereby realizing the mine car entry blocking cooperation;

[0034] At the same time, when the mine car moves to the inside of the baffle 446, the rocking plate 51 provided in the second car stop assembly 5 will be closed and opened to release the squeezing effect of the pressure head 53 provided at the upper end of the front side of the rocking plate 51 and the block 54 provided at the upper end of the rear side of the swing arm 55, so that the swing arm 55 cooperates with the weight of the front side to realize automatic swinging movement, and driven by the swing arm 55 to swing down, the blocking block 57 at the front side of the transmission is driven to rotate counterclockwise and lift between the second docking seat 58, so that the front end of the blocking block 57 is lifted to realize the blocking of the mine car axle, thereby realizing the secondary parking blocking, preventing the mine car from moving out to the exit side by itself, and achieving the significant enhancement of the parking blocking effect of the mine car;

[0035] If the axle blocking state needs to be released later, the rocking plate 51 can be closed to release the pressure head 53 provided at the upper end of the front side of the rocking plate 51 and the stop block 54 provided at the upper end of the rear side of the swing arm 55. In this way, the stop block 54 can indirectly drive the entire block block 57 to move the front end of the block block 57 downward, so that the blocking effect of the block block 57 on the axle is released. Secondly, when the block block 57 is reset, it will slightly push the axle to move the mine car, and when the mine car moves, it will squeeze the The baffle 446 provided at the upper end of the rotating seat 445 causes the rotating seat 445 to move backward along the connecting shaft 441 to squeeze the spring 443 between the fastening seat 442 and the gasket 444, thereby ensuring that there is a certain retreat space when the blocking block 57 is unlocked, ensuring that the blocking state of the axle is easily released, and the squeezed spring 443 can realize elastic reset transmission to automatically reset the rotating seat 445 and the baffle 446, thereby achieving auxiliary parking blocking and flexible unlocking transmission of the mine car axle.
