[0016] A method for using a shock absorbing device for highway engineering construction:

[0017] S1. Place the workpieces required for highway engineering construction on the surface of the load-bearing plate. The load-bearing plate will drop due to the gravity of the workpieces, which will drive the connecting column and the stabilizing ring to drop. Then the shock-absorbing spring will begin to compress and contact the upper rubber ring. Then the upper rubber ring will contact the upper surface of the lower rubber ring. At the same time, the moving rack plate will also drop. During the process of the moving rack plate dropping, the right side will contact the first gear inside the mounting frame. The first gear starts to rotate, and the first gear will drive the rotating cylinder to rotate. The convex column will slide inside the arc groove, thereby driving the telescopic column and the support block to move to the back. At this time, the support block will support the lowered load-bearing plate.

[0018] S2. When the rotating shaft rotates, the rotating shaft drives the first transmission mechanism to rotate, and then the first transmission mechanism drives the second transmission mechanism to rotate, and then the second transmission mechanism drives the screw body to rotate, and the movable sleeve slides on the surface of the screw body, and the screw body is supported and the moving trajectory is limited by the support ring, and then the screw body drives the positioning block and the locking frame to move to the back, and the locking frame slides to the outer surface of the locking block to limit the locking block, and the position of the locking block and the moving rack plate is locked;

[0019] S3. When the load-bearing plate descends, the load-bearing plate will also drive the lower pressure plate to descend. The lower surface of the lower pressure plate contacts the upper surface of the moving plate. The lower pressure plate presses the moving plate downward, and then the spring telescopic tube begins to extend and retract. When the moving plate descends, it drives the fixed rack plate downward, and then the fixed rack plate engages with the second gear, and the fixed rack plate begins to rotate clockwise. The fixed rack plate drives the rotating frame and the locking claw to rotate. At this time, the locking claw will rotate to the inside of the locking groove to limit and lock the position of the load-bearing plate. Finally, the workpiece on the surface of the load-bearing plate is placed as a whole and the position of the load-bearing plate is locked, thereby achieving a good shock absorption effect.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The shock absorbing device for highway engineering construction and the method of using the device include a damping hydraulic cylinder, a bearing plate, a connecting column, a stabilizing ring, a shock absorbing spring, an upper rubber ring, a lower rubber ring, a moving rack plate, a spring rotating shaft, a connecting block, a limiting block, a locking block, a mounting frame, a rotating shaft, a first gear, a rotating cylinder and a telescopic column. When in use, the workpiece required for highway engineering construction is placed on the surface of the bearing plate, and the damping hydraulic cylinder can be used for initial damping and shock absorption. Then the bearing plate will drop due to the gravity of the workpiece, and the connecting column and the stabilizing ring will be driven to drop at this time, and then the shock absorbing spring starts to compress and resist The upper rubber ring, and then the upper rubber ring will contact the upper surface of the lower rubber ring. When the upper rubber ring contacts the lower rubber ring, the sound is reduced when the two contact each other, realizing the functions of silencing and shock absorption. At the same time, the moving rack plate will also descend. During the descent of the moving rack plate, the right side contacts the first gear inside the mounting frame, and the first gear starts to rotate. The first gear will drive the rotating cylinder to rotate, and the convex column will slide inside the arc groove, thereby driving the telescopic column and the support block to move to the back. At this time, the support block will support the lowered load-bearing plate, and the rubber pad on the surface contacts the lower surface of the load-bearing plate, which can also realize The first transmission mechanism drives the second transmission mechanism to rotate, and then the second transmission mechanism drives the screw body to rotate. The movable sleeve slides on the surface of the screw body, and the screw body is supported and the moving trajectory is limited by the support ring. Then the screw body drives the positioning block and the locking frame to move to the back, and the locking frame slides to the outer surface of the locking block to limit the locking block. At this time, the position of the locking block and the moving rack plate is locked. Therefore, when a workpiece is placed on the surface of the carrier plate, the carrier plate will drop, and the workpiece will pass through the carrier plate. When the gravity drops to the lowest end, the lower surface of the supporting plate can be supported by the supporting block, and when the moving rack plate drops to a suitable position, the locking frame will be slidably installed on the outer surface of the limiting block to limit the position of the locking block, and the limiting block can limit the upward rotation angle of the locking block, so that the positions of the locking block and the moving rack plate remain stable. This design can achieve multiple shock-absorbing effects and can also lock the supporting plate after shock absorption to prevent the workpiece on the surface of the supporting plate from shaking during subsequent movement. Therefore, the overall shock-absorbing effect is better, reflecting the functionality of the design.

[0022] 2. The shock absorbing device for highway engineering construction and the method of using the device include a lower pressure plate, a spring telescopic cylinder, a moving plate, a fixed rack plate, a second gear, a rotating frame, a locking claw, a stabilizing plate and a rubber column sleeve. When the load-bearing plate is used, the load-bearing plate will also drive the lower pressure plate to descend, and the lower surface of the lower pressure plate will contact the upper surface of the moving plate. The lower pressure plate will press the moving plate downward, and then the spring telescopic cylinder will begin to extend and retract. When the moving plate moves downward, it will drive the fixed rack plate downward, and then the fixed rack plate will mesh with the second gear, and the fixed rack plate will start to rotate clockwise, and the fixed rack plate will drive the rotating frame and the locking claw to rotate, and then the locking claw will rotate to The position of the carrier plate is limited and locked inside the locking groove, and finally the position of the carrier plate is locked after the workpiece on the surface of the carrier plate is placed as a whole. Therefore, the design can lock the front and rear surfaces of the carrier plate at the same time, and can cooperate with the locking of the position of the moving rack plate, and the moving rack plate is installed at the lower end of the carrier plate, so that the position of the lower surface of the carrier plate can also be locked, that is, after the workpiece is placed on the surface of the carrier plate for initial shock absorption, the position of the carrier plate is then locked, that is, the position of the workpiece on the surface of the carrier plate is locked, so the shock-absorbing spring will not shake up and down, and the overall shock-absorbing and energy-absorbing effect is good, which reflects the ingenuity of the design.

When the components on the surface of the supporting plate 5 are moved out of the surface of the supporting plate 5 as a whole, the supporting plate 5 begins to be free from force and will automatically return to its original position under the elastic action of the shock-absorbing spring 8. Then the supporting plate 5 will drive the moving rack plate 11 and the lower pressure plate 31 to rise in turn, and then the moving rack plate 11 will contact the outer surface of the first gear 18. At this time, the support block 21 will automatically shrink away from the lower surface of the supporting plate 5.At the same time, the screw body 24 rotates to drive the movable sleeve 25 and the positioning block 26 to move. At this time, the locking frame 27 will slowly move away from the outer surface of the locking block 15. When the moving rack plate 11 rises, the locking block 15 will be tilted downward to a certain extent through the rotation of the spring shaft 12. At this time, the locking block 15 can be separated from the inside of the locking frame 27 and move upward. The limiting block 14 can limit the clockwise rotation of the locking block 15. When the locking block 15 rotates counterclockwise, the surface of the connecting block 13 is inclined. At this time, the connecting block 13 can rotate, and after the locking block 15 is separated from the inside of the locking frame 27 and moves upward, the spring shaft 1 2 can automatically restore to its original position due to its elasticity. At this time, the locking block 15 and the moving rack plate 11 are in a vertical state. Similarly, when the moving plate 33 is not affected by the lower pressure plate 31, it automatically restores to its original position through the spring telescopic cylinder 32, and the fixed rack plate 34 slides on the back of the second gear 35. The second gear 35 starts to rotate counterclockwise, which can drive the rotating frame 36 to rotate, so that the locking claw 37 will be out of the locking groove 29, that is, the carrier plate 5 can be automatically unlocked. Therefore, this design can lock the carrier plate 5 during the shock absorption process to prevent the workpiece on the surface of the carrier plate 5 from shaking when moving. The problem of vibration of the bearing plate 5 is solved. At the same time, the effect of silencing can be achieved while achieving shock absorption. When the bearing plate 5 descends, the bearing plate 5 will also drive the lower pressure plate 31 to descend. The lower surface of the lower pressure plate 31 contacts the upper surface of the moving plate 33. The lower pressure plate 31 presses the moving plate 33 downward, and then the spring telescopic cylinder 32 begins to telescope. When the moving plate 33 moves downward, it drives the fixed rack plate 34 downward, and then the fixed rack plate 34 engages with the second gear 35. The fixed rack plate 34 starts to rotate clockwise, and the fixed rack plate 34 drives the rotating frame 36 and the locking claw 37 to rotate. At this time, the locking claw 37 will rotate to the inner side of the locking groove 29. The position of the carrier plate 5 is limited and locked, and finally the position of the carrier plate 5 is locked after the workpiece on the surface of the carrier plate 5 is placed as a whole. Therefore, the present design can lock the front and rear surfaces of the carrier plate 5 at the same time, and can cooperate with the locking of the position of the moving rack plate 11, and the moving rack plate 11 is installed at the lower end of the carrier plate 5, so that the position of the lower surface of the carrier plate 5 can also be locked, that is, after the workpiece is placed on the surface of the carrier plate 5 for initial shock absorption, the position of the carrier plate 5 is then locked, that is, the position of the workpiece on the surface of the carrier plate 5 is locked, so the shock-absorbing spring 8 will not shake up and down, and the overall shock-absorbing energy absorption effect is better;,

[0037] A locking block 15 is installed on the front surface of the connecting block 13, the top surface of the connecting block 13 is in an arc shape, a limiting block 14 is installed on the outer surface of the moving rack plate 11, and the limiting block 14 is installed directly above the connecting block 13 and the locking block 15. A mounting frame 16 is installed on the surface of the mounting plate 3, and a rotating shaft 17 is inserted and installed inside the mounting frame 16. A first gear 18 is installed on the back of the rotating shaft 17, and a rotating cylinder 19 is installed on the back of the first gear 18. A telescopic column 20 is arranged inside the rotating cylinder 19, and a support block 21 is installed on the back of the telescopic column 20. A rubber pad is arranged on the upper surface of the support block 21, and a first transmission mechanism 22 is installed on the outer surface of the rotating shaft 17, and a second transmission mechanism 23 is arranged on the front surface of the first transmission mechanism 22. The front surface of the second transmission mechanism 23 is connected to a screw body 24, and a movable sleeve 25 is movably installed on the outer surface of the screw body 24. A positioning block 26 is installed on the left side of the movable sleeve 25, and a locking frame 27 is installed on the left surface of the positioning block 26. A stabilizing pad 28 is installed on the top surface of the inner wall of the locking frame 27. The right side of the lower end portion of the moving rack plate 11 is a smooth surface, and an arc groove is provided on the outer surface of the rotating cylinder 19. A convex column is provided inside the arc groove, and the convex column is fixedly connected to the telescopic column 20. A support ring is provided on the outer surface of the screw body 24, and the support ring is installed on the top surface of the mounting plate 3. The movable sleeve 25 is installed on the top surface of the mounting plate 3 to limit the sliding. The locking frame 27 and the locking block 15 are adapted to each other. The design of the support block 21 can also support the bearing plate 5 When the load-bearing plate 5 descends, the damping hydraulic cylinder 4 performs initial damping and shock absorption, and then the shock-absorbing spring 8 descends and is compressed, and the upper rubber ring 9 and the lower rubber ring 10 are in contact with each other, and the overall contact sound is small, so that the function of sound absorption and noise reduction can be achieved, and the function of shock absorption and buffering can also be achieved. At the same time, the buffer column 41 will also descend inside the buffer cylinder 42, and the buffer column 41 will contact the stabilizing spring 43 and the contact pad 44, which can also have a certain buffering effect. At the same time, when the buffer column 41 moves downward, the contact pad 44 can also achieve a sound absorption effect, and the sound generated by the overall contact is small. Finally, when the load-bearing plate 5 is subjected to gravity as a whole, the mounting plate 3 will also be subjected to gravity. At this time, the rubber part of the lower end of the support plate 2 will move downward to a certain extent. When the rubber column sleeve 39 is in contact with the inside of the rubber column tube 40, the sound of the rubber column sleeve 39 and the rubber column tube 40 will also be attenuated when they collide with each other, and the overall silencing effect is good. Therefore, in the present design, when the shock absorbing operation is realized, the sound generated when each group of shock absorbing components collide up and down is relatively small, which can achieve the silencing effect. The workpieces required for highway engineering construction are placed on the surface of the bearing plate 5, and the damping hydraulic cylinder 4 can perform initial damping and shock absorption. Then the bearing plate 5 will drop due to the gravity of the workpiece, and the connecting column 6 and the stabilizing ring 7 will be driven to drop at this time. Then the shock absorbing spring 8 begins to compress and collide with the upper rubber ring 9, and then the upper rubber ring 9 will collide with the upper surface of the lower rubber ring 10. When the upper rubber ring 9 collide with the lower rubber ring 10, the sound is reduced when the two collide.The functions of noise reduction and shock absorption are realized, and at the same time, the moving rack plate 11 will also descend. During the descent of the moving rack plate 11, the right side will contact the first gear 18 inside the mounting frame 16, and the first gear 18 will start to rotate. The first gear 18 will drive the rotating cylinder 19 to rotate, and the convex column will slide inside the arc groove, thereby driving the telescopic column 20 and the support block 21 to move to the back side. At this time, the support block 21 will support the lowered load-bearing plate 5, and the rubber pad on the surface will contact with the lower surface of the load-bearing plate 5, which can also achieve the shock absorption effect. Subsequently, when the rotating shaft 17 rotates, the rotating shaft 17 drives the first transmission mechanism 22 to rotate, and then the first transmission mechanism 22 will drive the second transmission mechanism 23 to rotate, and then the second transmission mechanism 23 will drive the screw body 24 to rotate, and the movable sleeve 25 will slide on the surface of the screw body 24, support the screw body 24 and limit the moving trajectory through the support ring, and then the screw body 24 drives The positioning block 26 and the locking frame 27 move to the back side, and the locking frame 27 slides to the outer surface of the locking block 15 to limit the locking block 15. At this time, the positions of the locking block 15 and the moving rack plate 11 are locked. Therefore, when a workpiece is placed on the surface of the carrier plate 5, the carrier plate 5 will drop. When the workpiece drops to the lowest end due to gravity, the lower surface of the carrier plate 5 can be supported by the support block 21. At the same time, when the moving rack plate 11 drops to a suitable position, the locking frame 27 will slide and be installed on the outer surface of the limiting block 14 to limit the position of the locking block 15. The limiting block 14 can limit the angle at which the locking block 15 can be rotated upward, so that the positions of the locking block 15 and the moving rack plate 11 remain stable. This design can achieve multiple shock-absorbing effects and can also lock the carrier plate 5 after shock absorption to prevent the workpiece on the surface of the carrier plate 5 from shaking during subsequent movement. Therefore, the overall shock-absorbing effect is relatively good.

[0038] A method for using a shock absorbing device for highway engineering construction:

[0039] S1. Place the workpieces required for highway engineering construction on the surface of the bearing plate 5. The bearing plate 5 will drop due to the gravity of the workpieces, which will drive the connecting column 6 and the stabilizing ring 7 to drop. Then the shock-absorbing spring 8 starts to compress and contact the upper rubber ring 9. Then the upper rubber ring 9 contacts the upper surface of the lower rubber ring 10. At the same time, the moving rack plate 11 will also drop. During the descent of the moving rack plate 11, the right side contacts the first gear 18 inside the mounting frame 16. The first gear 18 starts to rotate. The first gear 18 drives the rotating cylinder 19 to rotate. The convex column will slide inside the arc groove, thereby driving the telescopic column 20 and the support block 21 to move to the back. At this time, the support block 21 will support the lowered bearing plate 5.

[0040] S2. When the rotating shaft 17 rotates, the rotating shaft 17 drives the first transmission mechanism 22 to rotate, and then the first transmission mechanism 22 drives the second transmission mechanism 23 to rotate, and then the second transmission mechanism 23 drives the screw body 24 to rotate, and the movable sleeve 25 slides on the surface of the screw body 24, and the screw body 24 is supported and the moving trajectory is limited by the support ring, and then the screw body 24 drives the positioning block 26 and the locking frame 27 to move to the back, and the locking frame 27 slides to the outer surface of the locking block 15 to limit the locking block 15, and the position of the locking block 15 and the moving rack plate 11 is locked;

[0041] S3. When the supporting plate 5 descends, the supporting plate 5 will also drive the lower pressure plate 31 to descend. The lower surface of the lower pressure plate 31 contacts the upper surface of the moving plate 33. The lower pressure plate 31 presses the moving plate 33 downward, and then the spring telescopic cylinder 32 begins to extend and retract. When the moving plate 33 moves downward, it drives the fixed rack plate 34 downward, and then the fixed rack plate 34 engages with the second gear 35. The fixed rack plate 34 starts to rotate clockwise, and the fixed rack plate 34 drives the rotating frame 36 and the locking claw 37 to rotate. At this time, the locking claw 37 will rotate to the inside of the locking groove 29, and the position of the supporting plate 5 is limited and locked. Finally, after the workpiece on the surface of the supporting plate 5 is placed as a whole, the position of the supporting plate 5 is locked, thereby achieving a good shock absorption effect.

[0042] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device, place the workpieces required for highway construction on the surface of the bearing plate 5, and the damping hydraulic cylinder 4 can perform initial damping and shock absorption. Then the bearing plate 5 will drop due to the gravity of the workpiece, which will drive the connecting column 6 and the stabilizing ring 7 to drop. Then the shock absorbing spring 8 begins to compress and contact the upper rubber ring 9, and then the upper rubber ring 9 will contact the upper surface of the lower rubber ring 10. When the upper rubber ring 9 contacts the lower rubber ring 10, the two will contact. The noise is reduced, achieving the functions of silencing and shock absorption. At the same time, the moving rack plate 11 will also descend. During the descent of the moving rack plate 11, the right side will contact the first gear 18 inside the mounting frame 16. The first gear 18 starts to rotate, and the first gear 18 will drive the rotating cylinder 19 to rotate. The convex column will slide inside the arc groove, thereby driving the telescopic column 20 and the support block 21 to move to the back side. At this time, the support block 21 will support the descending load-bearing plate 5, and the rubber pad on the surface will contact the lower surface of the load-bearing plate 5, which can also achieve a shock absorption effect. Then when When the rotating shaft 17 rotates, the rotating shaft 17 drives the first transmission mechanism 22 to rotate, and then the first transmission mechanism 22 drives the second transmission mechanism 23 to rotate, and then the second transmission mechanism 23 drives the screw body 24 to rotate, and the movable sleeve 25 slides on the surface of the screw body 24, and the screw body 24 is supported and the movement trajectory is limited by the support ring, and then the screw body 24 drives the positioning block 26 and the locking frame 27 to move to the back, and the locking frame 27 slides to the outer surface of the locking block 15 to limit the locking block 15. At this time, the locking block 15 and the moving gear The position of the strip plate 11 is locked, so when a workpiece is placed on the surface of the carrier plate 5, the carrier plate 5 will drop. When the workpiece drops to the lowest end due to gravity, the lower surface of the carrier plate 5 can be supported by the support block 21. At the same time, when the moving rack plate 11 drops to a suitable position, the locking frame 27 will be slidably installed on the outer surface of the limiting block 14 to limit the position of the locking block 15. The limiting block 14 can limit the upward rotation angle of the locking block 15, so that the positions of the locking block 15 and the moving rack plate 11 remain stable.

[0043] When the supporting plate 5 descends, the supporting plate 5 will also drive the lower pressing plate 31 to descend, and the lower surface of the lower pressing plate 31 will contact the upper surface of the moving plate 33, and the lower pressing plate 31 will press the moving plate 33 downward, and then the spring telescopic cylinder 32 will begin to telescope, and when the moving plate 33 moves downward, it will drive the fixed rack plate 34 downward, and then the fixed rack plate 34 will mesh with the second gear 35, and the fixed rack plate 34 will start to rotate clockwise, and the fixed rack plate 34 will drive the rotating frame 36 and the locking claw 37 to rotate. At this time, the locking claw 37 will rotate to the inside of the locking groove 29, and the position of the supporting plate 5 will be limited and locked. Finally, after the workpiece on the surface of the supporting plate 5 is placed as a whole, the position of the supporting plate 5 is locked. Therefore, the present design can lock the front and rear surfaces of the supporting plate 5 at the same time, and can cooperate with the locking of the position of the moving rack plate 11, and the moving rack plate 11 is installed at the lower end of the supporting plate 5, so that the position of the lower surface of the supporting plate 5 can also be locked, that is, after the workpiece is placed on the surface of the supporting plate 5 for initial shock absorption, the position of the supporting plate 5 is then locked, that is, the position of the workpiece on the surface of the supporting plate 5 is locked, so the shock-absorbing spring 8 will not shake up and down. The above is all the working principles of the present invention.
