At the same time, the bellows sleeve is located on the outside of the spring, a through pipe is installed through the top of the bellows sleeve, a plug is embedded on the inner side of the through pipe, and a pull rope is installed on the top of the plug.

[0020] Preferably, the working steps of the buffer shock-absorbing structure are as follows:

[0021] S1. The staff can use one of the bushings to connect with the appropriate position of the climbing rail vehicle under the support of the ring according to the actual needs;

[0022] S2. Subsequently, the staff needs to push the screw rod to rotate through the push rod under the support of the L rod and the reinforcement of the fixed ring according to the actual needs. At the same time, the staff needs to pull the push rod along the through hole to adjust the position according to the actual situation to prevent the push rod from affecting the rotation of the screw rod, so that the screw rod can use the threaded action to push the movable rod to move to the left along the L rod under the action of external force and the support of the L rod, so that the movable rod can push the bushing close to the left side to the appropriate position through the fixed ring under the action of external force, and connect the fixed ring to the roller end of the climbing rail car through the bushing;

[0023] S3. Then, according to the actual needs, the staff can push the sleeve to rotate counterclockwise under the support of the main body through the rotating sleeve, so that the sleeve can drive the groove, positioning groove, adjustment groove and limit groove to rotate together under the action of external force, and use the inclination angle of the groove, positioning groove, adjustment groove and limit groove to push the sleeve to gradually move to the right under the resistance of the positioning block, so that the sleeve can cooperate with the groove, positioning groove, adjustment groove and limit groove under the resistance of the positioning block to push the rotating sleeve to move to the right together, so that the spring is squeezed and contracted by the rotating sleeve under the resistance of the pressure plate, thereby adjusting the preload force of the spring;

[0024] S4. When the climbing rail vehicle moves using its own rollers, the vehicle body will push the pressure plate and the guide rod toward the main body through the bushing and the ring under the action of external force and gravity with the support of the roller end, so that the pressure plate squeezes the spring to contract under the action of external force and the support of the rotating sleeve. At the same time, the guide rod will drive the piston to move along the inner side of the main body, so that the device can use the elastic force of the piston, the main body and the spring to perform buffering and shock-absorbing work.

[0025] Preferably, in the steps S2, S3 and S4, the following steps are also included:

[0026] S21. When the bushing near the left side is connected to the appropriate position of the roller end of the climbing rail vehicle, the staff can rotate the threaded rod through the push handle according to the actual needs, so that the threaded rod is pulled out from the inner side of the adjusting ring or the inner ring by the thread action of the bushing under the action of external force, and the fixing effect on the adjusting ring or the inner ring is released according to the actual needs, and the adjusting ring and the inner ring are removed or used according to the actual needs. Since the inner diameters of the inner ring and the adjusting ring are different, the inner diameter of the bushing can be adjusted under the support of the bushing, and then the inner ring, the adjusting ring or the inner side of the bushing are used to connect to the appropriate position of the roller end of the climbing rail vehicle;

[0027] S31. When the positioning slot is rotated to the outside of the positioning block, the spring will be slightly squeezed to adjust to a smaller preload force. When the adjusting slot is rotated to the outside of the positioning block, the spring will be further squeezed to adjust to a moderate preload force on the basis of the previous one. When the limiting slot is rotated to the outside of the positioning block, the spring will be further squeezed to adjust to a higher preload force on the basis of the adjusting slot.

[0028] S41. When the external force disappears, the spring will push the guide rod away from the main body under the support of the rotating sleeve, so that the guide rod pushes the piston along the inner side of the main body toward the direction close to the sleeve ring under the action of the external force, so that the piston and the spring return to their original positions.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

The staff needs to push the screw rod to rotate through the push rod under the support of the L-rod and the reinforcement of the fixed ring according to the actual needs. At the same time, the staff needs to pull the push rod along the through hole to adjust the position according to the actual situation to prevent the push rod from affecting the rotation of the screw rod, so that the screw rod can use the threaded action to push the movable rod to move to the left along the L-rod under the action of external force and the support of the L-rod, so that the movable rod can push the bushing close to the left side to the appropriate position through the fixed ring under the action of external force, and connect the fixed ring to the roller end of the climbing rail car through the bushing, so that the device can be convenient for the staff to adjust the length of the device according to the actual needs, making the device more flexible.

[0031] 2. The present invention is provided with a threaded rod, which can firmly support the push handle under the threaded support of the bushing, and the push handle can push the threaded rod to rotate under the action of external force, and the threaded rod can firmly support the inner ring and the adjusting ring by the threaded action. When the bushing near the left side is connected to the roller end of the climbing rail vehicle at a suitable position, the staff can rotate the threaded rod through the push handle according to the needs of actual conditions, so that the threaded rod can be pulled out from the inner side of the adjusting ring or the inner ring by the threaded action of the bushing under the action of external force, and the fixing effect on the adjusting ring or the inner ring can be released according to the needs of actual conditions, and the adjusting ring and the inner ring can be removed or used according to the needs of actual conditions. Due to the different inner diameters of the inner ring and the adjusting ring, the inner diameter size of the bushing can be adjusted under the support of the bushing, and then the inner side of the inner ring, the adjusting ring or the bushing is connected to the roller end of the climbing rail vehicle at a suitable position, so that the device can facilitate the staff to adjust the inner diameter of the bushing connected to the roller end of the climbing rail vehicle, making the device more flexible.

[0032] 3.

[0033] 4. The present invention is equipped with a bellows sleeve which is made of rubber and can be deformed under the action of external force and rebound after the external force disappears. When the pressure plate moves, the bellows sleeve will be squeezed, folded or stretched and unfolded under the support of the sleeve under the action of external force, so that the bellows sleeve can wrap the spring and the guide rod inside at any time to provide protection. At the same time, the staff can pull the plug through the pull rope according to the actual needs, so that the plug is pulled out from the inside of the through pipe to open the passage of the through pipe. Then the staff needs to inject lubricating oil into the inside of the bellows sleeve from the opening of the through pipe, so that the lubricating oil can flow freely to the outside of the spring and the guide rod, thereby providing protection for the spring and the guide rod and facilitating the staff to add lubricating oil to the guide rod of the device.

[0052] S1. The staff can use one of the bushings 23 to connect to the appropriate position of the body of the climbing rail vehicle under the support of the ring 6 according to the actual needs;

[0053] S2. Subsequently, the staff needs to push the screw rod 18 to rotate through the push rod 20 under the support of the L rod 15 and the reinforcement of the fixed ring 17 according to the actual needs. At the same time, the staff needs to pull the push rod 20 along the through hole 19 to adjust the position according to the actual situation to prevent the push rod 20 from affecting the rotation of the screw rod 18, so that the screw rod 18 can use the threaded action to push the movable rod 16 to move to the left along the L rod 15 under the action of external force and the support of the L rod 15, so that the movable rod 16 can push the bushing 23 close to the left side to the appropriate position through the fixed ring 22 under the action of external force, and connect the fixed ring 22 to the roller end of the climbing rail car through the bushing 23;

[0054] S3.

When the climbing rail vehicle moves using its own rollers, under the action of external force and gravity, the vehicle body will push the pressure plate 5 and the guide rod 3 toward the main body 1 through the bushing 23 and the ring 6 under the support of the roller end, so that the pressure plate 5 squeezes the spring 7 to contract under the action of external force and the support of the rotating sleeve 8. At the same time, the guide rod 3 will drive the piston 4 to move along the inner side of the main body 1, so that the device can use the elastic force of the piston 4, the main body 1 and the spring 7 to perform buffering and shock absorption work.

[0056] Furthermore, in steps S2, S3 and S4, the following steps are also included:

[0057] S21. When the bushing 23 near the left side is connected to the appropriate position of the roller end of the climbing rail vehicle, the staff can rotate the threaded rod 24 through the push handle 25 according to the actual needs, so that the threaded rod 24 is pulled out from the inner side of the adjusting ring 27 or the inner ring 26 by the thread action with the bushing 23 under the action of external force, and the fixing effect on the adjusting ring 27 or the inner ring 26 is released according to the actual needs, and the adjusting ring 27 and the inner ring 26 are removed or used according to the actual needs. Due to the different inner diameters of the inner ring 26 and the adjusting ring 27, the inner diameter of the bushing 23 can be adjusted under the support of the bushing 23, and then the inner ring 26, the adjusting ring 27 or the inner side of the bushing 23 are used to connect to the appropriate position of the roller end of the climbing rail vehicle;

[0058] S31, when the positioning slot 11 is rotated to the outside of the positioning block 14, the spring 7 will be slightly squeezed and adjusted to a smaller preload force, when the adjusting slot 12 is rotated to the outside of the positioning block 14, the spring 7 will be further squeezed and adjusted to a moderate preload force on the basis of the previous one, and when the limiting slot 13 is rotated to the outside of the positioning block 14, the spring 7 will be further squeezed and adjusted to a higher preload force on the basis of the adjusting slot 12;

[0059] S41. When the external force disappears, the spring 7 will push the guide rod 3 away from the main body 1 under the support of the rotating sleeve 8, so that the guide rod 3 pushes the piston 4 along the inner side of the main body 1 toward the direction close to the collar 6 under the action of the external force, so that the piston 4 and the spring 7 return to their original positions.

[0060] Working principle: Before using the device, check whether there are any problems that may affect its use.

5. According to the method for using the buffer shock-absorbing structure based on the climbing rail vehicle according to claim 4, the working steps of the buffer shock-absorbing structure are as follows: S1. The staff uses one of the bushings (23) to connect to a suitable position of the body of the climbing rail vehicle under the support of the collar (6) according to actual needs; S2. Subsequently, the staff needs to push the screw rod (18) to rotate through the push rod (20) under the support of the L rod (15) and the reinforcement of the fixed ring (17) according to the actual needs. At the same time, the staff needs to pull the push rod (20) along the through hole (19) to adjust the position according to the actual situation to prevent the push rod (20) from affecting the rotation of the screw rod (18), so that the screw rod (18) can use the threaded action to push the movable rod (16) to move to the left along the L rod (15) under the action of external force and the support of the L rod (15), so that the movable rod (16) can push the bushing (23) close to the left side to move to a suitable position through the fixed ring (22) under the action of external force, and connect the fixed ring (22) to the roller end of the climbing rail vehicle through the bushing (23); S3, then according to the actual needs, the staff pushes the sleeve (9) to rotate counterclockwise under the support of the main body (1) through the rotating sleeve (8), so that the sleeve (9) can drive the groove (10), the positioning groove (11), the adjustment groove (12) and the limit groove (13) to rotate together under the action of external force, and push the sleeve (9) gradually to the right side by utilizing the inclination angle of the groove (10), the positioning groove (11), the adjustment groove (12) and the limit groove (13) under the resistance of the positioning block (14), so that the sleeve (9) can cooperate with the groove (10), the positioning groove (11), the adjustment groove (12) and the limit groove (13) under the resistance of the positioning block (14) to push the rotating sleeve (8) to move to the right side together, so that the spring (7) is squeezed and contracted by the rotating sleeve (8) under the resistance of the pressure plate (5), thereby adjusting the preload force of the spring (7); S4. When the climbing rail vehicle moves using its own rollers, under the action of external force and gravity, the vehicle body, supported by the roller ends, pushes the pressure plate (5) and the guide rod (3) toward the main body (1) through the bushing (23) and the collar (6), so that the pressure plate (5) squeezes the spring (7) and contracts under the action of external force and the support of the rotary sleeve (8). At the same time, the guide rod (3) drives the piston (4) to move along the inner side of the main body (1), so that the buffer shock-absorbing structure can use the elastic force of the piston (4), the main body (1) and the spring (7) to perform buffer shock-absorbing work.

6. A method for using a buffer shock-absorbing structure based on a climbing rail vehicle according to claim 5, Features: In the steps S2, S3 and S4, the following steps are also included: S21. When the bushing (23) near the left side is connected to the appropriate position of the roller end of the climbing rail vehicle, the staff rotates the threaded rod (24) through the push handle (25) according to the actual needs, so that the threaded rod (24) is pulled out from the inner side of the adjusting ring (27) or the inner ring (26) by the thread action of the bushing (23) under the action of external force, and the fixing effect on the adjusting ring (27) or the inner ring (26) is released according to the actual needs, and the adjusting ring (27) and the inner ring (26) are removed or used according to the actual needs. Since the inner diameters of the inner ring (26) and the adjusting ring (27) are different, the inner diameter of the bushing (23) can be adjusted under the support of the bushing (23), and then the inner side of the inner ring (26), the adjusting ring (27) or the bushing (23) is used to connect to the appropriate position of the roller end of the climbing rail vehicle; S31, when the positioning groove (11) is rotated to the outside of the positioning block (14), the spring (7) is slightly squeezed and adjusted to a smaller preload force, when the adjustment groove (12) is rotated to the outside of the positioning block (14), the spring (7) is further squeezed and adjusted to a moderate preload force on the basis of the previous one, and when the limit groove (13) is rotated to the outside of the positioning block (14), the spring (7) is further squeezed and adjusted to a higher preload force on the basis of the adjustment groove (12); S41. When the external force disappears, the spring (7) will push the guide rod (3) in a direction away from the main body (1) under the support of the rotating sleeve (8), so that the guide rod (3) pushes the piston (4) along the inner side of the main body (1) in a direction close to the collar (6) under the action of the external force, so that the piston (4) and the spring (7) return to their original positions.
