Description

Technical Field

[0001] The invention relates to the technical field of mine car transportation, in particular to a collision type connection and disconnection mechanism for a mine car. Background Art

[0002] A mine car refers to a narrow-gauge railway transport vehicle used to transport bulk materials such as coal, ore and waste rock in mines. It is generally towed by a locomotive or winch. Mine cars are divided into five categories according to their structure and unloading method: fixed mine cars (material cars, flatbed cars), dump mine cars, single-sided curved track side-unloading mine cars, bottom (side) unloading mine cars and shuttle mine cars. Since the 1950s, mine cars have been connected together for use in underground mine transportation to improve the transportation efficiency of mine cars.

[0003] At present, when connecting the mine cars on the market, chains have been used to manually connect the mine cars one by one. The connection is very inconvenient, the operation is labor-intensive, and it is unsafe to operate, especially when the track bends left and right and rises and falls, the operation is more difficult. On the one hand, it not only consumes manpower, material resources and time, but on the other hand, the mine car is easy to be unhooked or broken during operation, and there are many unsafe factors. For this reason, we propose a collision-type connection and disconnection mechanism for mine cars. Summary of the invention

[0004] The object of the present invention is to provide a collision-type connection and disconnection mechanism for a mine car, so as to solve the problem raised in the above-mentioned background technology that when the mine cars on the market are connected, chains are always used to manually hook up the mine cars one by one, which is very inconvenient and labor-intensive to operate, and unsafe during operation, especially when the rails are bent left and right and up and down, the operation is more difficult. On the one hand, it not only consumes manpower, material resources and time, but also on the other hand, the mine car is easy to be unhooked or broken during operation, and there are many unsafe factors.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical scheme: a collision-type connection and disconnection mechanism for a mine car, comprising a first fixed plate, a hook and a second fixed plate, the left end of the first fixed plate is fixed with a first clamping block, and the upper and lower ends of the first clamping block are connected to the second clamping blocks, the outside of the second clamping block is fixed with a first spring, and the upper end of the first spring is connected with a baffle, the hook is installed on the left end of the second clamping block, and the outside of the hook is connected with a sliding ball, a guide rail is provided on the rear side of the sliding ball, and a bottom plate is installed on the rear side of the guide rail, a connecting plate is fixed on the left end of the bottom plate, and a shock-absorbing spring is installed on the left end of the connecting plate, the outside of the shock-absorbing spring is connected with a limiting plate, the second fixed plate is installed on the left end of the shock-absorbing spring, a screw hole is provided at the middle position of the bottom plate, and the second spring is fixed to the right end of the screw hole, a cover plate is placed on the upper end of the screw hole, and a screw is installed inside the screw hole, the upper and lower surfaces of the connecting plate are inlaid with sliding grooves, and the inside of the sliding groove is connected with a slider.

[0006] Preferably, the second clamping blocks are symmetrically distributed up and down about the horizontal center line of the first clamping block, and the first fixing plate forms a clamping structure with the bottom plate through the first clamping block and the second clamping block.

[0007] Preferably, the second clamping block forms an elastic structure through the first spring and the baffle, and the first spring, the second clamping block and the baffle are all connected by welding.

[0008] Preferably, the outer surface of the hook is tightly fitted with the sliding ball, and a sliding structure is formed between the sliding ball and the guide rail.

[0009] Preferably, the shock absorbing springs are evenly and equidistantly distributed between the connecting plate and the second fixing plate, and a semi-enclosed structure is formed between the limiting plate and the shock absorbing springs.

[0010] Preferably, the sizes of the slide groove and the slider match, and a sliding structure is formed between the slide groove and the slider.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The collision-type connection and disconnection mechanism of the mine car is provided with two second clamping blocks installed on the bottom plate, and the two second clamping blocks are symmetrically installed up and down, and a gap is formed between the two, and the first clamping block is installed on the first fixing plate. The bottom plate and the first fixing plate are fixed on two different mine cars. When the two mine cars collide with each other, the first clamping block can be stuck between the two second clamping blocks to complete the fixation. Compared with the traditional chain hanging, the operation is simple, the labor intensity is small, and it is conducive to reducing the burden on the staff;

[0013] 2. A first spring is set to be connected between the second clamping block and the baffle. When the first clamping block is inserted between the two second clamping blocks, the first spring is in a compressed state. Therefore, the elastic effect of the first spring itself can be used to reversely clamp the two second clamping blocks, so that the connection between the second clamping block and the first clamping block is tighter and not easy to fall off, thereby enhancing the safety of the mine car connection. A sliding ball is set to be close to the outside of the hook, and the sliding ball can move inside the guide rail. Therefore, when the sliding ball is squeezed inward, the hook will be forced to shrink inward, and the two second clamping blocks will stretch outward, thereby realizing the disengagement between the second clamping block and the first clamping block. The operation is simple and convenient for workers to use;

[0014] 3. A row of shock-absorbing springs are installed between the connecting plate and the second fixed plate. The shock-absorbing springs can use their own elastic effect to weaken the lateral tension exerted on the entire connecting mechanism, which is beneficial to maintaining the stability of the connecting mechanism. A limit plate is installed on the outside of the shock-absorbing spring. The limit plate limits the elastic effect of the shock-absorbing spring within a certain range, thereby achieving effective support, which helps to ensure the stability of the entire connecting mechanism. When the connecting plate and the second fixed plate are hit by external force, the slide groove and the slider can slide, providing a buffer space for the connection between the connecting plate and the second fixed plate, which is beneficial to extending the service life of the connecting plate and the second fixed plate.

The shock-absorbing spring 11 is evenly and equidistantly distributed between the connecting plate 10 and the second fixing plate 13, and a semi-enclosed structure is formed between the limiting plate 12 and the shock-absorbing spring 11. A row of shock-absorbing springs 11 are installed between the connecting plate 10 and the second fixing plate 13. The shock-absorbing spring 11 can use its own elastic effect to weaken the lateral tension of the entire connecting mechanism, which is beneficial to maintaining the stability of the connecting mechanism, and a limiting plate 12 is installed on the outside of the shock-absorbing spring 11.

[0023] Working principle: For this type of collision-type connection and disconnection mechanism for mine cars, first fix the first fixing plate 1 and the first clamping block 2 to the front of mine car A, and fix the second fixing plate 13, the bottom plate 9 and the connecting plate 10 to the rear of mine car B, and the horizontal center lines of these parts coincide with each other, cover the front of the bottom plate 9 with a cover plate 16, and screw 17 is screwed into the screw hole 14 from the bottom of the bottom plate 9, and a threading action occurs between the screw 17 and the cover plate 16 to fix the cover plate 16 on the bottom plate 9, and then place the mine car A at the rear of the mine car B. The first card block 2 is pushed from behind the mine cart A and the mine cart B, so that the mine cart A and the mine cart B collide with each other. At this time, the first card block 2 collides with the second card block 3. The pressure of the first card block 2 acts between the two second card blocks 3, so that the two second card blocks 3 expand outward. The first spring 4 is compressed and shortened between the second card block 3 and the baffle 5. Then the first card block 2 is inserted between the two second card blocks 3. The end of the first card block 2 compresses the second spring 15, so that the second spring 15 shortens. At this time, the first spring 4 shortens and generates a The reverse force acts on the two second clamping blocks 3, so that the two second clamping blocks 3 clamp the first clamping block 2 to complete the fixation. When the entire mechanism is hit during operation, the pressure acts on the shock-absorbing spring 11, so that the shock-absorbing spring 11 is compressed and shortened, so that the two limit plates 12 are in contact with each other for support. At this time, the slider 19 slides inside the slide groove 18 for buffering. At the same time, the shock-absorbing spring 11 generates a reverse force to offset part of the pressure and maintain the stability between the connecting plate 10 and the second fixing plate 13. When the two mine cars are to be disengaged, the sliding ball 7 is squeezed inwards, and the sliding ball 7 moves inside the guide rail 8 and applies pressure to the hook 6, causing the hook 6 to retract inwards. At the same time, the second clamping block 3 is expanded outwards, further compressing the first spring 4. Since the second spring 15 is in a compressed state, an upward rebound force will be generated. Therefore, when the distance between the two second clamping blocks 3 is greater than the width of the first clamping block 2, the second spring 15 pushes the first clamping block 2 out to complete the separation, thus completing the use process of the entire mine car collision connection and disengagement mechanism.
