When a train passes through the track, the track moves downwards to drive the first supporting plate 7 to move downwards, the second spring 6 is compressed, the first supporting plate 7 is enabled to damp the track due to the compression force of the second spring 6, the train passes through more stably, the second sliding rod 5 moves downwards to drive the second leather pad 701 to move downwards, the second leather pad 701 moves downwards to extrude the nitrogen, the nitrogen is extruded to generate a force, the second leather pad 701 moves downwards more slowly, the first leather pad 3 is pushed by the nitrogen to move upwards, the first leather pad 3 moves upwards to drive the guide rod 2 to move upwards, guide arm 2 upward movement supports it with first backup pad 7 contact for first backup pad 7 is more firm, and simultaneously, when second slide bar 5 moves down to suitable position, second slide bar 5 and buffer 4 contact, and then buffer 4 cushions second slide bar 5, makes the slower first backup pad 7 of drive of second slide bar 5 move down, and then further carries out the damping to the track, makes the damping effect better. When the train passes by, because of the effect of second spring 6, first backup pad 7 rebound resets, and then first backup pad 7 drives second leather pad 701 rebound through second slide bar 5 and resets, and second leather pad 701 rebound drives first leather pad 3 rebound through nitrogen gas and resets, and guide arm 2 also resets just.
When a train passes on the track, the second slide bar 5 moves downwards to contact with the first universal ball 406, because the upper part of the second slide bar 5 is thicker, the second slide bar 5 enables the first universal ball 406 to move outwards, the first universal ball 406 moves outwards to drive the first slide bar 403 to move outwards, the first spring 404 is compressed, and then due to the force compressed by the first spring 404, the first slide bar 403 enables the second slide bar 5 to move downwards more slowly through the first universal ball 406, so that the first support plate 7 further damps the track, and the damping effect is better. When the train passes by, the second slide bar 5 moves upwards to reset, and the first slide bar 403 moves inwards to drive the first universal ball 406 to move inwards to reset due to the action of the first spring 404.
When the guide rod 2 moves upwards, the guide rod 2 drives the sliding pipe 8 to move upwards, the fourth spring 10 is stretched, the sliding pipe 8 moves upwards to drive the second supporting plate 11 to move upwards, the second supporting plate 11 moves upwards to be in contact with the first supporting plate 7, and the second supporting plate 11 buffers the first supporting plate 7 under the action of the third spring 9. When the guide rod 2 moves downwards to reset, the slide tube 8 drives the second support plate 11 to move downwards to reset due to the action of the fourth spring 10. In this way, the first support plate 7 is prevented from being damaged by being violently contacted with the guide bar 2.
When the device is used for a long time and the nitrogen amount is insufficient, an operator can pull the fixed plate 15 to move forward, the fixed plate 15 moves forward to drive the second rotating shaft 17 to move forward through the second bearing 16, the second rotating shaft 17 moves forward to drive the handle 18 to move forward, the handle 18 moves forward to a proper distance, the fixed plate 15 is stopped to be pulled, the handle 18 is shaken to rotate reversely, the handle 18 rotates reversely to drive the second rotating shaft 17 to rotate reversely, the second rotating shaft 17 rotates reversely to drive the rotating disc 19 to rotate reversely, the rotating disc 19 rotates reversely to drive the fluted disc 22 to rotate forwardly, the fluted disc 22 rotates forwardly to drive the screw 21 to rotate forwardly, the screw 21 rotates forwardly through the nut 20 to move downwardly, the screw 21 moves downwardly to drive the rubber leather block 24 to move downwardly, the rubber leather block 24 moves downwardly to limit the space in the hollow supporting seat 1, so that the space is smaller, and when the rubber leather block 24 moves downwardly to a proper position, the, pulling fixed plate 15 rearward movement, and then drive handle 18 rearward movement and reset, because hollow support seat 1 inner space diminishes, second leather pad 701 moves down and promotes nitrogen gas then more difficult promotion, just also makes first backup pad 7 better to orbital damping effect. When the nitrogen gas of the hollow supporting seat 1 is little, people squeeze the nitrogen gas into the hollow supporting seat 1, so that the nitrogen gas in the hollow supporting seat 1 is sufficient, the handle 18 can be moved forwards to a proper position according to the operation, the handle 18 is shaken to rotate forwards, the screw rod 21 moves upwards to drive the rubber leather block 24 to move upwards to reset, the shaking of the handle 18 is stopped, and the handle 18 is reset. So, can adjust the dynamics of damping for the damping effect is better.
When an operator pulls the fixing plate 15 to move forwards, the fixing plate 15 enables the second universal ball 29 to be separated from the clamping groove 30, the fixing plate 15 enables the second universal ball 29 to move upwards, the second universal ball 29 moves upwards to drive the universal seat 28 to move upwards, the universal seat 28 moves upwards to drive the third sliding rod 26 to move upwards, the fifth spring 27 is stretched, after the rubber leather block 24 moves downwards to a proper position, the fixing plate 15 can be pulled to move backwards to reset, the clamping groove 30 moves to be right below the second universal ball 29, due to the effect of the fifth spring 27, the third sliding rod 26 moves downwards, the universal seat 28 drives the second universal ball 29 to move downwards to be clamped into the clamping groove 30, and the second universal ball 29 is matched with the clamping groove 30 to fix the fixing plate 15. Thus, the fixing plate 15 can be prevented from being moved freely to affect the subsequent use.
Although embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
