Description

Technical Field

[0001] The present invention relates to a linear calibration device for a lifting mechanism, belonging to the technical field of elevator calibration. Background Art

[0002] Since the elevator needs to be adjusted according to the on-site situation during installation and also requires fine-tuning of the position after installation, the elevator guide rails cannot be directly fixed by welding or other means, and only bolt parts can be used for fixing. During long-term use of the elevator, due to a large amount of vibration generated during operation, relative movement will occur between the structures of the elevator guide rails installed by bolt parts, which will cause individual guide rails to displace horizontally, and then lead to vertical misalignment of the guide rails, affecting the normal operation of the elevator.

[0003] For the conventional maintenance operation of linear calibration of the guide rails, special tools such as alignment cardboard and laser equipment are required. After precisely aligning adjacent guide rails with the special tools, the bolt parts of the guide rails are locked and fixed, thus completing the linear calibration operation. This makes the operation difficulty of the linear calibration operation relatively high, so the linear calibration operation of the guide rails is rather cumbersome. Summary of the Invention

[0004] The technical problem to be solved by the present invention is as follows: to provide a linear calibration device for a lifting mechanism, which solves the problem that in the prior art, special equipment is required to perform linear calibration on the guide rails, resulting in relatively high calibration difficulty.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions: A linear calibration device for a lifting mechanism, comprising: A support member, fixedly arranged with the wall An adjusting member, arranged on the support member A connecting structure, arranged on one side of the adjusting member A guide rail, fixed to the adjusting member through the connecting structure, and the guide rail extends vertically A movable marking block, arranged on the support member, the movable marking block moves synchronously with the adjusting member, the movable marking block abuts against the support member, and a marking assembly is arranged on the movable marking block Wherein, the adjusting member is detachably and fixedly connected to the support member, the support member, the adjusting member, the connecting structure and the guide rail form a counterweight guide rail group, there are several groups of counterweight guide rail groups arranged in the vertical direction, and the marking assembly is used to calibrate the position of the movable marking block.

[0006] By adopting the above technical solution, the supporting member is fixed to the wall, and then after the position of the adjusting member relative to the supporting member is adjusted, the adjusting member is fixed to the supporting member. Then, the guide rail is vertically fixed to the adjusting member through the connecting structure. At this time, a complete counterweight guide rail group is formed. A number of counterweight guide rail groups are repeatedly installed in the vertical direction to align several guide rails vertically, so as to achieve the stability of the lifting mechanism during movement. When the adjusting member slides relative to the supporting member after long-term use, resulting in the misalignment of the guide rails. Since the movable marking block moves synchronously with the adjusting member, scratches will be generated at the contact between the movable marking block and the supporting member at this time. During calibration, maintenance personnel do not need to rely on professional instruments and can directly adjust the position of the adjusting member according to the initial point of the scratch. Compared with the traditional calibration method, while ensuring the calibration accuracy, the calibration difficulty and complexity are reduced, and the calibration efficiency is improved. At the same time, the initial position of the movable marking block can also be calibrated through the marking component. Maintenance personnel adjust the position of the movable marking block according to the calibrated position, and then synchronously adjust the position of the guide rail through the adjusting member to restore the guide rail to its initial state, achieving the purpose of rapid calibration of the guide rail.

[0007] The present invention is further provided that: the connecting structure includes two oppositely arranged pressing members, a guide rail bottom plate is arranged between the pressing members, and the two pressing members are detachably fixed to the adjusting member. The pressing members apply a pressure towards the adjusting member to the guide rail bottom plate to fix the guide rail bottom plate to the adjusting member, and the guide rail is fixedly arranged on the end face of the guide rail bottom plate away from the adjusting member.

[0008] The present invention is further provided that: the marking component includes: a marking groove, which is opened on the side surface of the supporting member where the movable marking block is arranged, a pressing block, which is slidably connected to the movable marking block. The pressing block slides towards the marking groove and its end can extend into the marking groove. There is a space between the pressing block and the movable marking block, a fixed marking block, which is arranged in the space between the pressing block and the movable marking block and moves synchronously with the pressing block. The fixed marking block can abut against the pressing block, an embedding layer, which is fixedly arranged on the inner wall of the marking groove. The fixed marking block can be inserted into the embedding layer, a synchronization structure, which is arranged on the pressing block. The synchronization structure enables the fixed marking block and the pressing block to move synchronously or releases the synchronous movement between the fixed marking block and the pressing block.

[0009] The present invention is further provided that: the synchronization structure includes: a limiting block, one end of which is fixed to the fixed marking block. The axial direction of the limiting block is the same as the sliding direction of the pressing block, a rotating block, which is rotatably arranged on the pressing block. The rotating axial direction of the rotating block is the same as the axial direction of the limiting block, The limiting cavity is opened in the rotating block. A limiting hole is penetratingly opened on one side of the limiting cavity facing the marking groove. The connecting rod is fixed to the end of the limiting block away from the fixed marking block. The outer contour of the connecting rod is the same as the inner contour of the limiting hole. The connecting rod can pass through the limiting hole and extend into the limiting cavity.

[0010] By adopting the above technical solution, in the initial state, the connecting rod is located in the limiting cavity, and the outer contour of the connecting rod is not aligned with the inner contour of the marking groove. The fixed marking block moves synchronously with the rotating block through the limiting block. When several guide rails are vertically aligned and fixed, at this time, the adjusting member and the supporting member have been fixed. By pressing the pressing block to move in the direction towards the marking groove, at this time, the pressing block drives the limiting block towards the marking groove through the rotating block, and then drives the fixed marking block towards the marking groove to move, and finally inserts the fixed marking block into the embedding layer for fixation. Then rotate the rotating block to align the inner contour of the limiting hole with the outer contour of the connecting rod. At this time, the connecting rod can move out of the limiting cavity. As the pressing block is pulled and slides away from the marking groove, the pressing block gradually resets, and at this time, the fixed marking block is completely located in the marking groove, and the pressing block moves out of the marking groove. At this time, the pressing block follows the moving marking block to move. Since the limiting block is located between the moving marking block and the pressing block, the limiting block can move between the moving marking block and the pressing block, so that the moving marking block and the pressing block can move within a fixed range relative to the limiting block. At this time, when the adjusting member moves relative to the supporting member, the moving marking block and the pressing block move synchronously with the adjusting member. At this time, the moving marking block and the pressing block move relative to the limiting block and the fixed marking block, but the position of the fixed marking block remains unchanged. When calibrating the guide rail, by releasing the fixed connection between the supporting member and the adjusting member, the adjusting member can linearly slide relative to the supporting member, so that the adjusting member drives the moving marking block and the pressing block to adjust the position. Press the pressing block so that the end of the pressing block extends into the marking groove, and then by adjusting the positions of the moving marking block and the pressing block, make the pressing block abut against the fixed marking block again. At this time, the moving marking block and the pressing block return to the starting position, and the adjusting member also moves to the starting position synchronously. Therefore, the misaligned guide rail also returns to the initial position. Through the positioning mark of the fixed marking block, when calibrating the guide rail linearly, the misaligned guide rail can be quickly adjusted to the initial position, and there is no need to use external laser positioning equipment or other professional equipment, which further improves the calibration efficiency and also ensures the calibration accuracy.

[0011] The present invention is further configured such that there is a gap between two guide rails in adjacent counterweight guide rail groups, and a filling structure for filling the gap is provided in the gap.

[0012] The present invention is further configured such that the filling structure includes: The filling block has two ends respectively abutting against the two guide rails. An inflatable cavity is circumferentially provided on the outer side that is not in contact with the guide rail. The inflatable cavity penetrates through the outer side of the filling block to communicate the inflatable cavity with the outside of the filling block. An expansion layer is fixedly arranged in the inflatable cavity. The expansion layer separates and seals the inflatable cavity from the outside of the filling block. A slot is provided on the end face of the guide rail facing the filling block. A plug-in block is fixed on the outer side of the filling block and is inserted into the slot.

[0013] The present invention is further configured as follows: A fixing block is detachably and fixedly arranged on the support member. The inside of the fixing block is a hollow structure forming an activity cavity. A communication channel is provided on one side of the activity cavity facing the adjusting member. A sliding block is slidably arranged in the activity cavity. A synchronization block is fixed on one side of the sliding block facing the adjusting member. The end of the synchronization block extends to the outside of the fixing block through the communication channel and is fixed to the adjusting member. One side of the synchronization block located outside the fixing block is fixed to the activity marking block.

[0014] The present invention is further configured as follows: An inflatable box is fixedly arranged on the fixing block. The inside of the inflatable box is a cavity and is filled with compressed gas. An air guide cavity is arranged in the wall body of the communication channel. An intermediate cavity is communicated and opened on one side of the inflatable box facing the air guide cavity. The air guide cavity is communicated with the intermediate cavity. A sealing structure is arranged in the air guide cavity to seal and separate the air guide cavity and the intermediate cavity. An air guide pipe is communicatedly arranged in the air guide cavity. One end of the air guide pipe far from the air guide cavity is fixed to the filling block and is communicated with the inflatable cavity.

[0015] The present invention is further configured as follows: The sealing structure includes: A sealing plate is slidably arranged in the air guide cavity. The sealing plate is in sealing fit with the inner wall of the air guide cavity. A sealing block is fixed on one side of the sealing plate facing the intermediate cavity. The end of the sealing block extends into the intermediate cavity. The sealing block is in sealing contact with the inner wall of the intermediate cavity. A plurality of air guide holes are provided on the side wall of the sealing block. The air guide holes can move into the air guide cavity along with the sealing block and be communicated with the air guide cavity. An activity shaft extends through the communication channel. Both ends of the activity shaft penetrate to the outside of the fixing block. A sliding groove extending towards the synchronization block is provided at the connection between the fixing block and the activity shaft. The activity shaft slides along the extending direction of the sliding groove. Nuts in threaded connection with the outer side of the fixing block are arranged at both ends of the activity shaft. A turning plate is arranged in the communication channel. The turning plate is rotatably connected to the activity shaft. The end of the turning plate extends towards the direction of the synchronization block. The turning plate blocks the communication channel. A torsion spring is arranged at the rotational connection between the turning plate and the activity shaft. A serrated layer is arranged on the side of the synchronization block facing the turning plate. The end of the turning plate can be in contact with the serrated layer. A pull rope has one end fixed to the sealing plate. The other end of the pull rope extends into the communication channel and is fixed to one end of the turning plate far from the serrated layer. A sealing spring is arranged between the sealing plate and the end wall of the air guide cavity away from the middle cavity.

[0016] By adopting the above technical solution, when the adjusting member displaces relative to the supporting member, the adjusting member drives the synchronous block to slide. Since the end of the flipping plate abuts against the serrated layer, at this time, the serrated layer applies a flipping force to the abutting end of the flipping plate, causing the flipping plate to flip around the movable shaft. When the flipping plate flips, the end of the flipping plate connected to the pulling rope pulls the pulling rope out of the air guide cavity. At this time, the sealing plate drives the sealing block to move towards the air guide cavity, and makes the air guide hole communicate with the air guide cavity. At this time, the gas in the inflating box enters the sealing block and enters the air guide cavity through the air guide hole, and then is introduced into the inflating cavity through the air guide pipe. At this time, after the air pressure in the inflating cavity increases, the expanding layer expands, so that the expanding layer overflows from the gap between the two guide rails. At this time, when the guide rails are misaligned, the expanded expanding layer can compensate for the misaligned ends of the guide rails, so that when the lifting mechanism passes through the misalignment point of the two guide rails, it first contacts the expanding layer and buffers, reducing the hard collision between the lifting mechanism and the guide rails, which is beneficial to improving the service life of the lifting mechanism and the guide rails, and can reduce the noise during the operation of the lifting mechanism.

[0017] The present invention is further arranged as follows: a supporting spring is arranged in the movable cavity, and both ends of the supporting spring are fixed to the side surface of the sliding block away from the synchronous block and the inner wall of the movable cavity respectively.

[0018] The beneficial effects of the present invention are as follows: fix the supporting member to the wall, and then fix the adjusting member to the supporting member after adjusting the position of the adjusting member relative to the supporting member. Then, vertically fix the guide rail to the adjusting member through the connecting structure. At this time, a complete counterweight guide rail group is formed. Repeat the installation of several groups of counterweight guide rail groups in the vertical direction to make several guide rails vertically aligned to achieve the stability of the lifting mechanism during movement. When the adjusting member slides relative to the supporting member after long-term use, the guide rails are misaligned. Since the movable marking block moves synchronously with the adjusting member, scratches will be generated at the abutting position of the movable marking block and the supporting member at this time. During calibration, maintenance personnel do not need to rely on professional instruments and can directly adjust the position of the adjusting member according to the initial point of the scratches. Compared with the traditional calibration method, while ensuring the calibration accuracy, it reduces the calibration difficulty and complexity and improves the calibration efficiency.

Detailed implementation manners

[0021] In order to facilitate understanding of the technical means, creative features, achieved purposes and effects of the present invention, the present invention will be further described below with reference to specific drawings.

[0022] Such as Figures 1 to 2As shown, a linear calibration device for a lifting mechanism includes a support member 10, an adjusting member 11, a guide rail 14, a movable marking block 40, and a connecting structure. The support member 10 is fixedly arranged with the wall body, and the end of the support member 10 away from the wall body is a planar end extending horizontally. The adjusting member 11 is arranged on the planar end of the support member 10, and the adjusting member 11 and the support member 10 are detachably and fixedly connected through bolt fasteners. The connecting structure is arranged on one side of the adjusting member 11, and the guide rail 14 is fixed to the adjusting member 11 through the connecting structure, and the guide rail 14 extends in the vertical direction. The movable marking block 40 is arranged on the support member 10, and the movable marking block 40 moves synchronously with the adjusting member 11. The movable marking block 40 abuts against the support member 10, and when the movable marking block 40 slides relative to the support member 10, a scratch is made on the support member 10. The support member 10, the adjusting member 11, the connecting structure, and the guide rail 14 form a counterweight guide rail group. A plurality of groups of counterweight guide rail groups are arranged in the vertical direction, and the guide rails 14 in the plurality of groups of counterweight guide rail groups together form a counterweight guide rail. The lifting mechanism can slide along the counterweight guide rail, and a marking assembly for calibrating the position of the movable marking block 40 is arranged on the movable marking block 40. The connecting structure includes two oppositely arranged pressing members 12. A guide rail bottom plate 13 abutting against the adjusting member 11 is arranged between the pressing members 12. The two pressing members 12 are detachably fixed to the adjusting member 11 through bolt fasteners. One end of the pressing member 12 abuts against the side surface of the guide rail bottom plate 13 away from the adjusting member 11. The pressing member 12 applies a pressure towards the adjusting member 11 to the guide rail bottom plate 13 to fix the guide rail bottom plate 13 to the adjusting member 11. The guide rail 14 is fixedly arranged on the end surface of the guide rail bottom plate 13 away from the adjusting member 11.

[0023] As Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the marking assembly includes a marking groove 16, a pressing block 41, a fixed marking block 43, an embedding layer and a synchronization structure. The marking groove 16 is opened on the side of the supporting member 10 where the movable marking block 40 is arranged. The pressing block 41 is located on one side of the movable marking block 40. The pressing block 41 is arranged in an L shape. One end of the pressing block 41 is slidably connected to the movable marking block 40, and the other end of the pressing block 41 extends toward the marking groove 16 and can be moved into the marking groove 16. Due to the L shape of the pressing block 41, there is a space between the pressing block 41 and the movable marking block 40, and the movable marking The sliding connection between the block 40 and the pressing block 41 is provided with a pressing slot 42 extending toward the marking groove 16, and the pressing block 41 partially extends into the pressing slot 42. A return spring is fixedly arranged between the portion of the pressing block 41 located in the pressing slot 42 and the end wall of the pressing slot 42 facing the marking groove 16, and the return spring applies an elastic force to the pressing block 41 to move away from the marking groove 16. The fixed marking block 43 is arranged in the space between the pressing block 41 and the movable marking block 40 and moves synchronously with the pressing block 41, and the fixed marking block 43 can abut against the pressing block 41. The embedded layer is fixedly arranged on the inner wall of the marking groove 16, and the end of the fixed marking block 43 facing the marking groove 16 is a tip structure, and the tip structure enables the fixed marking block 43 to be inserted into the embedded layer. The tip structure includes a needle tip, a pin tip, and a screw tip structure, so that the tip structure can be normally inserted into the embedded layer. The material of the embedded layer includes wood, hard rubber, plastic and other materials that can be pierced. The synchronization structure is arranged on the pressing block 41, and the synchronization structure makes the fixed marking block 43 move synchronously with the pressing block 41 or releases the synchronous movement of the fixed marking block 43 and the pressing block 41. The elastic force of the reset spring is much smaller than the force for pulling the fixed marking block 43 out of the embedding layer.

[0024] like Figure 6 and Figure 7As shown in the figure, the synchronization structure includes a rotating block 44, a limiting cavity 45, a limiting block 47, and a connecting rod 48. One end of the limiting block 47 is fixed on the fixed marking block 43, and the axial direction of the limiting block 47 is the same as the sliding direction of the pressing block 41. The rotating block 44 is rotatably arranged on the pressing block 41, and the axial direction of the rotating shaft of the rotating block 44 is the same as the axial direction of the limiting block 47. The limiting cavity 45 is opened in the rotating block 44, and a limiting hole 46 is penetrated through the side of the limiting cavity 45 facing the marking groove 16. The inner contour of the limiting hole 46 is a polygon such as a trapezoid or a rectangle. The connecting rod 48 is fixed at one end of the limiting block 47 away from the fixed marking block 43, and the outer contour of the connecting rod 48 is the same as the inner contour of the limiting hole 46. When the outer contour of the connecting rod 48 is aligned with the inner contour of the limiting hole 46, the connecting rod 48 can pass through the limiting hole 46 and extend into the limiting cavity 45. When the connecting rod 48 is located in the limiting cavity 45 and the outer contour of the connecting rod 48 is not aligned with the inner contour of the limiting hole 46, since the connecting rod 48 cannot pass through the limiting hole 46, at this time, the rotating block 44 is clamped with the connecting rod 48, so that the limiting block 47 and the rotating block 44 move synchronously. When the end of the fixed marking block 43 is inserted into the embedding layer, the end of the connecting rod 48 located in the limiting cavity 45 abuts against the end wall on the side of the limiting cavity 45 away from the limiting hole 46. To ensure the accuracy when rotating the rotating block 44, mark scales that can be aligned with each other can be selectively opened on the outer side surface of the pressing block 41 in the radial direction of the rotating block 44 and on the outer curved surface of the rotating block 44. When the two mark scales are aligned, the inner contour of the limiting hole 46 is aligned with the outer contour of the connecting rod 48.

[0025] As Figure 1 shown, there is a gap between two guide rails 14 in the adjacent counterweight guide rail group, and a filling structure for filling the gap is arranged in the gap. The gap is arranged between the adjacent guide rails 14 mainly to avoid resonance of several guide rails 14. At the same time, filling structures with different materials are arranged in the gap, which not only avoids the transmission of the vibration frequency of the guide rails 14 through the filling structure, but also can supplement the gap to avoid abnormal noises when the lifting mechanism moves through the gap. The filling structure includes a filling block 23, an air inflation cavity 30, an expansion layer 31, and a plug-in block 32. The filling block 23 is arranged between the two guide rails 14, and both ends of the filling block 23 are respectively abutted against the two guide rails 14. The air inflation cavity 30 is circumferentially opened on the outer side surface that is not abutted against the guide rail 14, and the air inflation cavity 30 penetrates through the outer side surface of the filling block 23 to communicate the air inflation cavity 30 with the outside of the filling block 23. The expansion layer 31 is fixedly arranged in the air inflation cavity 30, and the expansion layer 31 separates and seals the air inflation cavity 30 from the outside of the filling block 23. After the air pressure in the air inflation cavity 30 increases, the expansion layer 31 will expand towards the outside of the filling block 23. A slot is opened on the end surface of the guide rail 14 facing the filling block 23, and the plug-in block 32 is fixed on the outer side surface of the filling block 23 and is inserted into the slot.

[0026] The inflatable cavity 30 in the filling structure can be selectively communicated with the air guide pipes 22 in a single or multiple counterweight guide rail groups at the same time. When a single inflatable cavity 30 is communicated with a single air guide pipe 22, several filling structures from bottom to top are respectively communicated with several fixing blocks 20 from bottom to top in a one-to-one correspondence.

[0027] As Figures 1 to 5 shown, the support member 10 is detachably and fixedly provided with a fixing block 20 through a bolt fastener. The fixing block 20 is located on the side of the adjusting member 11 close to the wall. The inside of the fixing block 20 is a hollow structure to form a movable cavity 28. A communication channel is provided on the side of the movable cavity 28 facing the adjusting member 11. A sliding block 27 is slidably arranged in the movable cavity 28. A support spring 29 is arranged in the movable cavity 28. Two ends of the support spring 29 are respectively fixed to the side surface of the sliding block 27 away from the synchronization block 25 and the inner wall of the movable cavity 28. The elastic force of the support spring 29 can only keep the synchronization block 25 outside the fixing block 20 and is much smaller than the friction force between the adjusting member 11 and the support member 10. A synchronization block 25 is fixed to the side of the sliding block 27 facing the adjusting member 11. The end of the synchronization block 25 extends outside the fixing block 20 through the communication channel and is fixed to the adjusting member 11. The fixing methods include but are not limited to welding and bonding. The side of the synchronization block 25 outside the fixing block 20 is fixed to the movable marking block 40. A gas filling box 21 is fixedly arranged on the side of the fixing block 20 away from the installation surface of the corresponding support member 10. The inside of the gas filling box 21 is cavity-shaped and filled with compressed gas. An air guide cavity 33 is arranged in the wall body on the side of the communication channel facing the gas filling box 21. An intermediate cavity 35 is communicated and opened on the side of the gas filling box 21 facing the air guide cavity 33. The air guide cavity 33 is communicated with the intermediate cavity 35. A sealing structure for sealing and separating the air guide cavity 33 and the intermediate cavity 35 is arranged in the air guide cavity 33. An air guide pipe 22 is communicated and arranged in the air guide cavity 33. One end of the air guide pipe 22 away from the air guide cavity 33 is fixed to the filling block 23 and communicated with the inflatable cavity 30.

[0028] As Figure 4As shown, the sealing structure includes a movable shaft 17, a guide rail 14, a marking groove 16, a sealing plate 34, a sealing block 36, a sealing spring 38, and a pull rope 39. The sealing plate 34 is slidably arranged in the air guide cavity 33. The sealing plate 34 reciprocally slides in the direction from the air guide cavity 33 towards the intermediate cavity 35, and the sealing plate 34 is in sealing fit with the inner wall of the air guide cavity 33. The sealing block 36 is fixed to the side of the sealing plate 34 facing the intermediate cavity 35. The end of the sealing block 36 extends into the intermediate cavity 35, and the sealing block 36 is in sealing abutment with the inner wall of the intermediate cavity 35. The inside of the sealing block 36 is an air inlet cavity with an opening facing the inflation box 21. A plurality of air guide holes 37 communicating the intermediate cavity 35 with the air inlet cavity are provided on the side wall of the sealing block 36. The air guide holes 37 can move into the air guide cavity 33 following the sealing block 36 and connect the air inlet cavity with the air guide cavity 33. At this time, the inside of the inflation box 21, the intermediate cavity 35, the air inlet cavity, the air guide holes 37, and the air guide cavity 33 are interconnected. The extending path of the movable shaft 17 horizontally passes through the communication channel in a certain direction. Both ends of the movable shaft 17 penetrate to the opposite outer sides of the fixed block 20. A sliding groove extending towards the synchronizing block 25 is provided at the connection between the fixed block 20 and the movable shaft 17. The movable shaft 17 slides along the extending direction of the sliding groove. Threaded connections are provided at both ends of the movable shaft 17 with nuts that abut against the outer side surface of the fixed block 20. A turnover plate 24 is arranged in the communication channel. The turnover plate 24 is rotatably connected to the movable shaft 17. One end of one side of the turnover plate 24 extends towards the synchronizing block 25, and the other end of the other side of the turnover plate 24 extends towards the air guide cavity 33. The turnover plate 24 locally blocks the communication channel. A torsion spring is provided at the rotational connection between the turnover plate 24 and the movable shaft 17. When the nut rotates and the movable shaft 17 remains stationary, the nut moves towards the inside of the fixed block 20 under the action of the thread structure and tightly abuts against the outer side surface of the fixed block 20. At this time, as the nut further rotates, the frictional force between the nut and the outer side surface of the fixed block 20 can fully satisfy the gravity of the turnover plate 24 and the movable shaft 17, maintaining the stability of the turnover plate 24 and the movable shaft 17. A serrated layer 26 is fixedly arranged on the side of the synchronizing block 25 facing the turnover plate 24. The end of the turnover plate 24 can abut against the serrated layer 26. Since the serrated layer 26 has a serrated structure, when the serrated layer 26 moves linearly, by the end of the turnover plate 24 abutting against the serrated inclined surface of the serrated layer 26, the serrated layer 26 flips along the circumferential direction of the movable shaft 17, and the torsion spring is compressed. When the serrated layer 26 disengages from abutment with the movable shaft 17, the turnover plate 24 flips back to its original position under the action of the torsion spring, so that the end of the turnover plate 24 continues to abut against the serrated inclined surface of the subsequent serrated layer 26. One end of the pull rope 39 is fixed to the sealing plate 34, and the other end of the pull rope 39 extends into the communication channel and is fixed to the end of the turnover plate 24 away from the serrated layer 26. The sealing spring 38 is arranged between the sealing plate 34 and the end wall of the air guide cavity 33 far from the intermediate cavity 35. The sealing spring 38 applies an elastic force towards the intermediate cavity 35 to the sealing plate 34. A limiting post for restricting the relative sliding of the sealing spring 38 with respect to the inner wall of the air guide cavity 33 is also fixedly arranged at the connection between the sealing spring 38 and the inner wall of the air guide cavity 33.

[0029] Fix the support member 10 to the wall, then adjust the position of the adjusting member 11 relative to the support member 10 and fix the adjusting member 11 to the support member 10. Then, vertically fix the guide rail 14 to the adjusting member 11 through the connecting structure. At this time, a complete counterweight guide rail group is formed. Repeat the installation of several groups of counterweight guide rail groups in the vertical direction to align several guide rails 14 vertically to achieve the stability of the lifting mechanism during movement. When the adjusting member 11 slides relative to the support member 10 after long-term use, the guide rail 14 is displaced. Since the movable marking block 40 moves synchronously with the adjusting member 11, scratches will be generated at the contact between the movable marking block 40 and the support member 10 at this time. During calibration, maintenance personnel do not need to rely on professional instruments and can directly adjust the position of the adjusting member 11 according to the initial point of the scratch. Compared with the traditional calibration method, while ensuring the calibration accuracy, the calibration complexity is reduced and the calibration efficiency is improved. At the same time, the initial position of the movable marking block 40 can be calibrated through the marking assembly. Maintenance personnel adjust the position of the movable marking block 40 according to the calibrated position, and then synchronously adjust the position of the guide rail 14 through the adjusting member 11 to restore the guide rail 14 to its initial state, achieving the purpose of quickly calibrating the guide rail 14.

[0030] In the initial state, the connecting rod 48 is located in the limiting cavity 45, and the outer contour of the connecting rod 48 is not aligned with the inner contour of the marking groove 16. The fixed marking block 43 moves synchronously with the rotating block 44 through the limiting block 47. When several guide rails 14 are vertically aligned and fixed, at this time, the adjusting member 11 and the support member 10 are already fixed. Press the pressing block 41 to move it in the direction towards the marking groove 16. At this time, the pressing block 41 drives the limiting block 47 towards the marking groove 16 through the rotating block 44, and then drives the fixed marking block 43 towards the marking groove 16. Finally, the tip of the fixed marking block 43 is inserted into the embedding layer for fixation, and the end of the pressing block 41 in contact with the fixed marking block 43 is completely inserted into the marking groove 16. Then rotate the rotating block 44 to align the inner contour of the limiting hole 46 with the outer contour of the connecting rod 48. At this time, the connecting rod 48 can be moved out of the limiting cavity 45. As the pressing block 41 is pulled and slides away from the marking groove 16, the pressing block 41 gradually returns to its original position, and the connecting rod 48 moves out of the limiting cavity 45. And at this time, the fixed marking block 43 is completely located in the marking groove 16, and the pressing block 41 moves out of the marking groove 16. At this time, the pressing block 41 moves with the movable marking block 40. Since the limiting block 47 is located between the movable marking block 40 and the pressing block 41, the limiting block 47 can move between the movable marking block 40 and the pressing block 41, enabling the limiting block 47 to move within a fixed range relative to the movable marking block 40 and the pressing block 41, and the fixed range is the range between the movable marking block 40 and the pressing block 41.

[0031] When the adjusting member 11 moves relative to the supporting member 10, that is, when the adjacent guide rails 14 are misaligned, the movable marking block 40 and the pressing block 41 will move synchronously with the adjusting member 11. At this time, the movable marking block 40 and the pressing block 41 move relative to the limiting block 47 and the fixed marking block 43, but the position of the fixed marking block 43 remains unchanged. When manually calibrating the guide rail 14 subsequently, by releasing the fixed connection between the supporting member 10 and the adjusting member 11, the adjusting member 11 can linearly slide relative to the supporting member 10, so that the adjusting member 11 drives the movable marking block 40 and the pressing block 41 to adjust their positions, press the pressing block 41, so that the end of the pressing block 41 extends into the marking groove 16 and does not completely insert into the marking groove 16. Then, by adjusting the positions of the movable marking block 40 and the pressing block 41, the pressing block 41 abuts and fits against the fixed marking block 43 again at one end of the marking groove 16. The movable marking block 40 and the pressing block 41 return to the starting position relative to the fixed marking block 43, and the adjusting member 11 also moves to the starting position synchronously. Therefore, the misaligned guide rail 14 also returns to the initial position. Through the positioning mark of the fixed marking block 43, when calibrating the guide rail 14 linearly, the misaligned guide rail 14 can be quickly adjusted to the initial position without using external laser positioning equipment or other professional equipment, further improving the calibration efficiency and ensuring the calibration accuracy at the same time.

[0032] And if it is necessary to temporarily lock the adjusting member 11 to limit the movement of the adjusting member 11, when the end of the pressing block 41 does not completely insert into the marking groove 16 and abuts against the fixed marking block 43, the limiting block 47 is coaxial with the rotating block 44, and one end of the connecting rod 48 provided on the limiting block 47 has not contacted one end of the limiting hole 46 opened on the rotating block 44. Then rotate the rotating block 44 to align the inner contour of the limiting hole 46 with the outer contour of the connecting rod 48. Then continue to press the pressing block 41 to make the pressing block 41 move further into the marking groove 16. Finally, the connecting rod 48 passes through the limiting hole 46 and enters the limiting cavity 45. Then rotate the rotating block 44 to misalign the limiting hole 46 and the connecting rod 48. At this time, the movable marking block 40 and the pressing block 41 are connected to the fixed marking block 43 through the limiting block 47. Therefore, the adjusting member 11 cannot move, achieving the effect of temporarily locking the adjusting member 11. When unlocking the adjusting member 11, only need to operate according to the steps of separating the rotating block 44 from the connecting rod 48 when installing the fixed marking block 43.

[0033] When maintenance personnel operate incorrectly and continuously press the end of the pressing block 41 into the marking groove 16 when pressing the pressing block 41, the end of the connecting rod 48 first abuts against the part of the pressing block 41 where the rotating block 44 is provided. At this time, the pressing block 41 cannot be further pressed into the marking groove 16. It is necessary to first adjust the pressing block 41 to abut against the fixed marking block 43 so that the rotating block 44 and the limiting block 47 are coaxial. By rotating the rotating block 44, the limiting hole 46 is aligned with the connecting rod 48 and the connecting rod 48 is inserted into the limiting cavity 45, and then the pressing block 41 can continue to be pressed into the marking groove 16. Therefore, it is beneficial to reduce the probability of operation errors of the calibration device.

[0034] When it is necessary to re-adjust the positions of all the guide rails 14 in the lifting mechanism, that is, to re-plan the positions of the guide rails 14 to adapt to the new counterweight size, it is necessary to remove the original marked fixed marking block 43. First, press the pressing block 41 and press the end of the pressing block 41 into the marking groove 16 but not completely into the marking groove 16. At this time, the end of the limiting block 47 where the connecting rod 48 is provided has not contacted the end of the rotating block 44 where the limiting hole 46 is opened. Then, disassemble and separate the bolt fasteners between the support member 10 and the adjusting member 11, and then adjust the position of the adjusting member 11 so that the adjusting member 11 drives the movable marking block 40 to move, so that the part of the pressing block 41 located in the marking groove 16 abuts against the fixed marking block 43. Then the rotating block 44 and the limiting block 47 are in a coaxial state and the rotating block 44 is rotated so that the inner contour of the limiting hole 46 is aligned with the outer contour of the connecting rod 48. By pressing the pressing block 41 in the direction towards the marking groove 16, the connecting rod 48 is inserted into the limiting cavity 45. Then, the rotating block 44 is rotated so that the inner contour of the limiting hole 46 is misaligned with the outer contour of the connecting rod 48. At this time, the rotating block 44 can form a clamping structure with the connecting rod 48. Then, the pressing block 41 is pushed to move away from the marking groove 16, so that the fixed marking block 43 is pulled out of the embedding layer through the rotating block 44 and the limiting block 47. At this time, it can follow the guide rail 14 for a new position replacement. When the new position is determined, repeating the above process of inserting the fixed marking block 43 can complete the re-marking of the fixed marking block 43, achieving the purpose of reusing the fixed marking block 43 and improving the service life of the calibration device.

[0035] When the adjusting member 11 displaces relative to the supporting member 10, the adjusting member 11 drives the synchronous block 25 to slide. Since the end of the turning plate 24 abuts against the serrated layer 26, at this time, the serrated layer 26 applies a turning force to the abutting end of the turning plate 24, causing the turning plate 24 to turn around the movable shaft 17. When the turning plate 24 turns, the end of the turning plate 24 connected to the pull rope 39 pulls the pull rope 39 out of the air guide cavity 33. At this time, the sealing plate 34 drives the sealing block 36 to move towards the air guide cavity 33, and the air guide hole 37 communicates with the air guide cavity 33. At this time, the gas in the inflation box 21 enters the sealing block 36 and enters the air guide cavity 33 through the air guide hole 37, and then is introduced into the inflation cavity 30 through the air guide pipe 22. At this time, after the air pressure in the inflation cavity 30 increases, the expansion layer 31 expands, so that the expansion layer 31 overflows from the gap between the two guide rails 14. At this time, when the guide rails are misaligned, the expanded expansion layer 31 can compensate for the end of the misaligned guide rail 14, so that when the lifting mechanism passes through the misalignment point of the two guide rails 14, it first contacts the expansion layer 31 and buffers, reducing the hard collision between the lifting mechanism and the guide rail 14, which is beneficial to improving the service life of the lifting mechanism and the guide rail 14, and can reduce the noise during the operation of the lifting mechanism.
