Description

Technical Field

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

[0002] Since the position of the elevator needs to be adjusted according to the on-site conditions during installation, and the position also needs to be fine-tuned after installation, the elevator guide rails cannot be directly fixed by welding or other means, and can only be fixed with bolts. When the elevator is used for a long time, the elevator will generate a lot of vibration during operation. At this time, relative movement will occur between the structures where the elevator guide rails are installed by bolts, causing individual guide rails to be displaced horizontally, which in turn causes the guide rails to be misaligned in the vertical direction, affecting the normal operation of the elevator.

[0003] Conventional inspection and maintenance work on the linear calibration of guide rails requires the use of special tools such as marking cardboard and laser equipment. After using professional tools to accurately align adjacent guide rails, the bolts of the guide rails are tightened to complete the linear calibration work. This makes the linear calibration work more difficult to operate, and the linear calibration operation of the guide rails is relatively cumbersome. Summary of the Invention

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

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: A linear calibration device for a lifting mechanism, comprising:

[0006] Supporting components, fixed to the wall,

[0007] an adjusting member, disposed on the supporting member,

[0008] The connecting structure is provided on one side of the adjusting member.

[0009] The guide rail is fixed to the adjustment member through the connecting structure, and the guide rail extends vertically.

[0010] The movable marking block is arranged on the supporting member. The movable marking block moves synchronously with the adjusting member. The movable marking block abuts against the supporting member. The movable marking block is provided with a marking component.

[0011] Among them, the adjusting member and the supporting member are detachably fixedly connected, and the supporting member, adjusting member, connecting structure and guide rail form a counterweight guide rail group. There are several groups of counterweight guide rail groups along the vertical direction, and the marking component is used to calibrate the position of the movable marking block.

[0012] By adopting the above technical solution, the support member is fixed to the wall, and then the position of the adjustment member relative to the support member is adjusted. The adjustment member is fixed to the support member, and then the guide rail is vertically fixed to the adjustment member through the connecting structure. At this time, a complete counterweight guide rail assembly is formed. Several sets of counterweight guide rail assemblies are repeatedly installed in the vertical direction so that the multiple guide rails are vertically aligned to achieve the stability of the lifting mechanism during movement. After long-term use, the adjustment member slides relative to the support member, causing the guide rail to misalign. Since the movable marker moves synchronously with the adjustment member, scratches will be generated at the contact point between the movable marker block and the support member. During calibration, maintenance personnel do not need to use professional equipment and can directly align the position of the adjustment member according to the initial point of the scratch. Compared with traditional calibration methods, while ensuring calibration accuracy, the difficulty and tediousness of calibration are reduced, and calibration efficiency is improved. At the same time, the initial position of the movable marker block can be calibrated by the marking assembly. The maintenance personnel adjust the position of the movable marker block according to the calibrated position, and then adjust the position of the guide rail through the adjustment member to restore the guide rail to its initial state, achieving the purpose of rapid guide rail calibration.

[0013] The present invention is further configured as follows: the connecting structure includes two relatively arranged clamping members, a guide rail base plate is arranged between the clamping members, the two clamping members are detachably fixed to the adjusting member, the clamping members apply pressure to the guide rail base plate toward the adjusting member to fix the guide rail base plate to the adjusting member, and the guide rail is fixedly arranged on one side end face of the guide rail base plate away from the adjusting member.

[0014] The present invention is further configured as follows: the marking component comprises:

[0015] The marking groove is opened on the side of the supporting structure where the movable marking block is set.

[0016] The pressing block is slidably connected to the movable marking block. The pressing block slides toward the marking groove and the end thereof can extend into the marking groove. There is space between the pressing block and the movable marking block.

[0017] The fixed marking block 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.

[0018] The embedded layer is fixedly arranged on the inner wall of the marking groove, and the fixed marking block can be plugged into the embedded layer.

[0019] The synchronization structure is arranged on the pressing block, and the synchronization structure enables the fixed marking block and the pressing block to move synchronously or releases the synchronous movement of the fixed marking block and the pressing block.

[0020] The present invention is further configured as follows: the synchronization structure includes:

[0021] The limit block has one end fixed on the fixed marking block, and the axial direction of the limit block is the same as the sliding direction of the pressing block.

[0022] The rotating block is rotatably arranged on the pressing block, and the rotating axis of the rotating block is the same as the axis of the limiting block.

[0023] The limiting cavity is provided in the rotating block, and a limiting hole is provided through the side of the limiting cavity facing the marking groove.

[0024] The connecting rod is fixed to one 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.

[0025] 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 limiting hole. The fixed marking block moves synchronously with the rotating block through the limiting block. When several guide rails are vertically aligned and fixed, the adjusting member and the supporting member are already fixed. By pressing the pressing block, it moves in the direction toward the marking groove. At this time, the pressing block drives the limiting block to move toward the marking groove through the rotating block, and then drives the fixed marking block to move toward the marking groove, and finally the fixed marking block is inserted into the embedded layer and fixed, and then the rotating block is rotated to align the inner contour of the limiting hole with the outer contour of the connecting rod. At this time, the connecting rod can be moved out of the limiting cavity. As the pressing block is pulled away from the marking groove and slides, 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 movement of the movable marking block. Since the limiting block is located between the movable marking block and the pressing block, the limiting block can move between the movable marking block and the pressing block, so that the movable marking block and the pressing block can move within a fixed range relative to the limiting block. Movement, at this time, after the adjusting member moves relative to the supporting member, the movable marking block and the pressing block move synchronously with the adjusting member, at this time the movable marking block and the pressing block move relative to the limit block and the fixed marking block, but the position of the fixed marking block remains unchanged, when the guide rail is calibrated, by releasing the fixed connection between the supporting member and the adjusting member, the adjusting member can slide linearly relative to the supporting member, so that the adjusting member drives the movable 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 position of the movable marking block and the pressing block, the pressing block is re-engaged with the fixed marking block, at this time, the movable marking block and the pressing block return to the starting position, and the adjusting member also moves synchronously to the starting position, so that the misaligned guide rail also returns to its initial position, through the positioning mark of the fixed marking block, when the guide rail is linearly calibrated, 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 ensures the accuracy of the calibration.

DETAILED DESCRIPTION

[0054] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further explained below with reference to specific illustrations.

[0055] like Figures 1 to 2 As 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 fixed to the wall, and the end of the support member 10 away from the wall is a horizontally extending flat end. The adjusting member 11 is arranged at the flat end of the support member 10, and the adjusting member 11 and the support member 10 are detachably fixedly connected by 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 scratches are engraved on the support member 10 when the movable marking block 40 slides relative to the support member 10. The supporting member 10, the adjusting member 11, the connecting structure and the guide rail 14 form a counterweight guide rail group. There are several groups of counterweight guide rail groups in the vertical direction. The guide rails 14 in the several groups of counterweight guide rail groups together constitute the counterweight guide rail. The lifting mechanism can slide along the counterweight guide rail. The movable marking block 40 is provided with a marking component for calibrating the position of the movable marking block 40. The connecting structure includes two oppositely arranged clamping members 12. A guide rail base plate 13 abutting against the adjusting member 11 is provided between the clamping members 12. The two clamping members 12 are detachably fixed to the adjusting member 11 by bolt fasteners. One end of the clamping member 12 abuts against the side of the guide rail base plate 13 away from the adjusting member 11. The clamping member 12 applies pressure to the guide rail base plate 13 toward the adjusting member 11 to fix the guide rail base plate 13 to the adjusting member 11. The guide rail 14 is fixed to the end face of the guide rail base plate 13 away from the adjusting member 11.

[0056] like Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As 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 set. The pressing block 41 is located on one side of the movable marking block 40. The pressing block 41 is set 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 groove 42 extending toward the marking groove 16. The pressing block 41 partially extends into the pressing groove 42. A return spring is fixedly provided between the portion of the pressing block 41 located in the pressing groove 42 and the end wall of the pressing groove 42 facing the marking groove 16. The return spring applies elastic force to the pressing block 41 to move away from the marking groove 16. The fixed marking block 43 is provided in the space between the pressing block 41 and the movable marking block 40 and moves synchronously with the pressing block 41. The fixed marking block 43 can abut against the pressing block 41. The embedded layer is fixedly provided on the inner wall of the marking groove 16. The end of the fixed marking block 43 facing the marking groove 16 is a pointed structure. The pointed structure enables the fixed marking block 43 to be inserted into the embedded layer. The pointed structure includes a needle tip, a pin tip, and a screw tip structure, so that the pointed structure can be normally inserted into the embedded layer. The materials of the embedded layer include wood, hard rubber, plastic, and other materials that can be pierced. The synchronization structure is provided on the pressing block 41, and the synchronization structure enables the fixed marking block 43 to 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 return spring is much smaller than the force for pulling the fixed marking block 43 out of the embedded layer.

[0057] like Figure 6 and Figure 7As shown, 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 to the fixed marking block 43, and the axial direction of the limiting block 47 is aligned with the sliding direction of the pressing block 41. The rotating block 44 is rotatably mounted on the pressing block 41, and the axial direction of the rotating block 44's rotation axis is aligned with the axial direction of the limiting block 47. The limiting cavity 45 is defined within the rotating block 44. A limiting hole 46 is formed through the limiting cavity 45 on the side facing the marking groove 16. The inner contour of the limiting hole 46 is a polygonal shape such as a trapezoid or rectangle. The connecting rod 48 is fixed to the end of the limiting block 47 away from the fixed marking block 43. 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, the connecting rod 48 cannot pass through the limiting hole 46. At this time, the rotating block 44 engages with the connecting rod 48, causing the limiting block 47 and the rotating block 44 to move synchronously. When the end of the fixed marking block 43 is inserted into the embedded layer, the end of the connecting rod 48 located in the limiting cavity 45 abuts against the end wall of the limiting cavity 45 away from the limiting hole 46. In order to ensure the accuracy when rotating the rotating block 44, marking scales that can be aligned with each other can be optionally opened on the radial outer surface of the pressing block 41 of the rotating block 44 and the outer curved surface of the rotating block 44. When the marking scales of the two are aligned, the inner contour of the limiting hole 46 is aligned with the outer contour of the connecting rod 48.

[0058] like Figure 1 As shown, there is a gap between two guide rails 14 in adjacent counterweight guide rail groups, and a filling structure is provided in the gap to fill the gap. The gap between adjacent guide rails 14 is mainly used to prevent resonance between the guide rails 14. At the same time, the filling structure made of different materials is provided in the gap to prevent the vibration frequency of the guide rails 14 from being transmitted through the filling structure, and to supplement the gap, thereby preventing abnormal noise when the lifting mechanism moves through the gap. The filling structure includes a filling block 23, an air-filled 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 the two ends of the filling block 23 respectively abut the two guide rails 14. The air-filled cavity 30 is opened around the outer side that is not abutted by the guide rail 14. The air-filled cavity 30 penetrates the outer side of the filling block 23 to connect the air-filled cavity 30 with the outside of the filling block 23. The expansion layer 31 is fixedly arranged in the air-filled cavity 30. The expansion layer 31 separates and seals the air-filled cavity 30 from the outside of the filling block 23. When the air pressure in the air-filled cavity 30 increases, the expansion layer 31 will expand toward the outside of the filling block 23. A slot is defined on the end surface of the guide rail 14 facing the filling block 23 , and the plug-in block 32 is fixed to the outer side surface of the filling block 23 and plugged into the slot.

[0059] The inflation cavity 30 in the filling structure can be selectively connected to the air duct 22 in a single or multiple counterweight guide rail groups at the same time. When a single inflation cavity 30 is connected to a single air duct 22, several filling structures from bottom to top are respectively connected to several fixed blocks 20 from bottom to top.

[0060] like Figures 1 to 5 As shown, the support member 10 is removably secured to a fixed block 20 via bolt fasteners. The fixed block 20 is located on the side of the adjustment member 11 closest to the wall. The fixed block 20 has a hollow structure forming a movable cavity 28. The movable cavity 28 has a connecting passage on the side facing the adjustment member 11. A sliding block 27 is slidably disposed within the movable cavity 28. A support spring 29 is disposed within the movable cavity 28. The ends of the support spring 29 are secured to the side of the sliding block 27 facing away from the synchronization block 25 and to the inner wall of the movable cavity 28, respectively. The elastic force of the support spring 29 is sufficient to maintain the synchronization block 25 outside the fixed block 20 and is significantly less than the friction between the adjustment member 11 and the support member 10. The synchronization block 25 is secured to the side of the sliding block 27 facing the adjustment member 11. The end of the synchronization block 25 extends to the outside of the fixed block 20 through a connecting passage and is secured to the adjustment member 11. The securing methods include, but are not limited to, welding and bonding. The side of the synchronization block 25 located outside the fixed block 20 is secured to the movable marking block 40. An air-filling box 21 is fixedly provided on the side of the fixed block 20 away from the mounting surface of the supporting member 10. The interior of the air-filling box 21 is hollow and filled with compressed gas. An air-guiding cavity 33 is provided in the wall of the connecting channel facing the air-filling box 21. An intermediate cavity 35 is provided on the side of the air-filling box 21 facing the air-guiding cavity 33. The air-guiding cavity 33 is connected to the intermediate cavity 35. A sealing structure is provided in the air-guiding cavity 33 for sealing and separating the air-guiding cavity 33 and the intermediate cavity 35. An air-guiding pipe 22 is provided in the air-guiding cavity 33. One end of the air-guiding pipe 22 away from the air-guiding cavity 33 is fixed to the filling block 23 and is connected to the air-filling cavity 30.

[0061] like Figure 4As shown, the sealing structure includes a movable shaft 17, a flip plate 24, a serrated layer 26, a sealing plate 34, a sealing block 36, a sealing spring 38, and a pull rope 39. The sealing plate 34 is slidably disposed within the air guide cavity 33. The sealing plate 34 reciprocates from the air guide cavity 33 toward the intermediate cavity 35, and the sealing plate 34 is in sealing contact 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 contact with the inner wall of the intermediate cavity 35. The interior of the sealing block 36 is an air intake cavity opening toward the inflation box 21. The side wall of the sealing block 36 is provided with a plurality of air guide holes 37 connecting the intermediate cavity 35 with the air intake cavity. The air guide holes 37 can follow the sealing block 36 to move into the air guide cavity 33 and connect the air intake cavity with the air guide cavity 33. At this time, the interior of the inflation box 21, the intermediate cavity 35, the air intake cavity, the air guide holes 37 and the air guide cavity 33 are connected to each other. The extension path of the movable shaft 17 passes through the connecting channel horizontally along the direction, and the two ends of the movable shaft 17 pass through the relatively outside of the fixed block 20. The connection between the fixed block 20 and the movable shaft 17 is provided with a sliding groove extending toward the synchronization block 25. The movable shaft 17 slides along the extension direction of the sliding groove. The two ends of the movable shaft 17 are threadedly connected with nuts that abut the outer side surface of the fixed block 20. The flip plate 24 is arranged in the connecting channel. The flip plate 24 is rotatably connected to the movable shaft 17. One side end of the flip plate 24 extends toward the direction of the synchronization block 25, and the other side end of the flip plate 24 extends toward the direction of the air guide cavity 33. The flip plate 24 partially blocks the connecting channel, and a torsion spring is provided at the rotation connection between the flip plate 24 and the movable shaft 17. When the nut rotates while the movable shaft 17 remains stationary, the nut, driven by the threaded structure, moves toward the interior of the fixed block 20 and tightly abuts the outer surface of the fixed block 20. As the nut rotates further, the friction between the nut and the outer surface of the fixed block 20 fully offsets the weight of the flip plate 24 and the movable shaft 17, maintaining the stability of the flip plate 24 and the movable shaft 17. A serrated layer 26 is fixed to the side of the synchronization block 25 facing the flip plate 24. The end of the flip plate 24 can abut against the serrated layer 26. Due to the serrated structure of the serrated layer 26, when the serrated layer 26 moves linearly, the end of the flip plate 24 abuts against the serrated inclined surface of the serrated layer 26, causing the flip plate 24 to flip along the circumferential direction of the movable shaft 17, compressing the torsion spring. When the serrated layer 26 disengages from the flip plate 24, the flip plate 24 resets and flips under the action of the torsion spring, causing the flip plate 24 to continue abutting against the serrated inclined surface of the subsequent serrated layer 26. One end of a pull cord 39 is fixed to the sealing plate 34, and the other end of the pull cord 39 extends into the communication channel and is fixed to the end of the flip plate 24 away from the serrated layer 26. A sealing spring 38 is disposed between the sealing plate 34 and the end wall of the air guide cavity 33 away from the intermediate cavity 35. The sealing spring 38 applies an elastic force to the sealing plate 34 toward the intermediate cavity 35.A limiting column is fixedly provided at the connection between the sealing spring 38 and the inner wall of the air guide cavity 33 for limiting the sliding of the sealing spring 38 relative to the inner wall of the air guide cavity 33.

[0062] After fixing the supporting member 10 to the wall, and then adjusting the position of the adjusting member 11 relative to the supporting member 10, fix the adjusting member 11 to the supporting member 10, and then fix the guide rail 14 vertically on 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 so that several guide rails 14 are vertically aligned to achieve the stability of the lifting mechanism during movement. After long-term use, the adjusting member 11 slides relative to the supporting member 10, causing the guide rail 14 to be misaligned. Since the movable marking block 40 moves synchronously with the adjusting member 11, scratches will be generated at the contact point between the movable marking block 40 and the supporting member 10. During calibration, maintenance personnel do not need to use professional equipment, and can directly align and 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, it reduces the calibration complexity and improves the calibration efficiency. At the same time, the initial position of the movable marking block 40 can be calibrated through the marking component. The 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 component 11 to restore the guide rail 14 to its initial state, thereby achieving the purpose of rapid calibration of the guide rail 14.

[0063] 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 limiting hole 46. 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, the adjusting member 11 and the supporting member 10 are fixed at this time. By pressing the pressing block 41, it moves toward the marking groove 16. At this time, the pressing block 41 drives the limiting block 47 to move toward the marking groove 16 through the rotating block 44, and then drives the fixed marking block 43 to move toward the marking groove 16, and finally the tip of the fixed marking block 43 is inserted into the embedded layer and fixed, 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, the rotating block 44 is rotated 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 removed from the limiting cavity 45. As the pressing block 41 is pulled away from the marking groove 16, the pressing block 41 gradually returns to its original position, and the connecting rod 48 is removed from the limiting cavity 45. At this time, the fixed marking block 43 is completely located in the marking groove 16, and the pressing block 41 is removed from the marking groove 16. At this time, the pressing block 41 follows the movement of 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, so that the limiting block 47 can move within a fixed range relative to the movable marking block 40 and the pressing block 41. The fixed range is the range between the movable marking block 40 and the pressing block 41.

[0064] 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 limit block 47 and the fixed marking block 43, but the position of the fixed marking block 43 remains unchanged. When the guide rails 14 are subsequently manually calibrated, the fixed connection between the supporting member 10 and the adjusting member 11 is released, so that the adjusting member 11 can slide linearly relative to the supporting member 10, so that the adjusting member 11 can slide linearly relative to the supporting member 10. The movable marking block 40 and the pressing block 41 are driven to adjust their positions, and the pressing block 41 is pressed so that the end of the pressing block 41 extends into the marking groove 16 but is not fully inserted into the marking groove 16. Then, by adjusting the positions of the movable marking block 40 and the pressing block 41, the end of the pressing block 41 located in the marking groove 16 is re-adapted to the fixed marking block 43. The movable marking block 40 and the pressing block 41 return to their starting positions relative to the fixed marking block 43, and the adjusting member 11 also moves synchronously to its starting position, so that the misaligned guide rail 14 also returns to its initial position. By using the positioning mark of the fixed marking block 43, when calibrating the guide rail 14 in a straight line, the misaligned guide rail 14 can be quickly adjusted to its initial position without the need for external laser positioning equipment or other professional equipment, thereby further improving the calibration efficiency and ensuring the accuracy of the calibration.

[0065] 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 is not fully inserted into the marking groove 16 and the fixed marking block 43 is abutted, the limit block 47 is coaxial with the rotating block 44, and the end of the connecting rod 48 provided on the limit block 47 has not yet contacted the end of the rotating block 44 where the limiting hole 46 is provided. Then, the rotating block 44 is rotated to adjust the inner contour of the limiting hole 46 to be aligned with the outer contour of the connecting rod 48, and then the pressing block 41 is continued to be pressed so that the pressing block 41 continues to move toward the marking groove 16. The movable marking block 40 and the pressing block 41 are connected to the fixed marking block 43 through the limiting block 47, so that the adjusting member 11 cannot move, thereby achieving the effect of temporarily locking the adjusting member 11. When the adjusting member 11 needs to be unlocked, it is only necessary to follow the steps of disengaging the rotating block 44 from the connecting rod 48 when installing the fixed marking block 43.

[0066] When the maintenance personnel make an operational error and continue to press the end of the pressing block 41 into the marking groove 16 while 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 set. At this time, the pressing block 41 cannot be further pressed into the marking groove 16. The pressing block 41 must first be adjusted to abut against the fixed marking block 43 so that the rotating block 44 is coaxial with the limit block 47. After the limit hole 46 is aligned with the connecting rod 48 by rotating the rotating block 44 and the connecting rod 48 is inserted into the limit cavity 45, the pressing block 41 can continue to be pressed into the marking groove 16. This helps to reduce the probability of operational errors of the calibration device.

[0067] When it is necessary to readjust 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, the original marking fixed marking block 43 needs to be removed, and the pressing block 41 is pressed first to press the end of the pressing block 41 into the marking groove 16 but not completely pressed into the marking groove 16. At this time, one end of the connecting rod 48 provided on the limit block 47 has not yet contacted the end of the rotating block 44 where the limiting hole 46 is provided. Then, the bolt fasteners between the supporting member 10 and the adjusting member 11 are disassembled and separated, and the position of the adjusting member 11 is adjusted 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 limit block 47 are coaxial and the rotating block 44 is rotated to align the inner contour of the limit hole 46 with the outer contour of the connecting rod 48. By pressing the pressing block 41 in the direction of the marking groove 16, the connecting rod 48 is inserted into the limit cavity 45, and then the rotating block 44 is rotated to misalign the inner contour of the limit hole 46 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, and then push the pressing block 41 to move away from the marking groove 16, thereby pulling the fixed marking block 43 out of the embedded layer through the rotating block 44 and the limit block 47. At this time, it can follow the guide rail 14 to replace the new position. When the new position is determined, repeat the above-mentioned insertion process of the fixed marking block 43 to complete the re-marking of the fixed marking block 43, thereby achieving the purpose of reusing the fixed marking block 43 and improving the service life of the calibration equipment.

[0068] When the adjusting member 11 is displaced relative to the supporting member 10, the adjusting member 11 drives the synchronous block 25 to slide. Since the end of the flip plate 24 abuts against the serrated layer 26, the serrated layer 26 applies a flipping force to the abutting end of the flip plate 24, causing the flip plate 24 to flip with the movable shaft 17 as the axis. When the flip plate 24 flips, the end of the flip 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 toward the air guide cavity 33 and connects the air guide hole 37 with the air guide cavity 33. At this time, the gas in the inflatable box 21 enters the sealing block 36 and passes through The air guide hole 37 enters the air guide cavity 33, and is then introduced into the inflation cavity 30 through the air guide tube 22. At this time, the air pressure in the inflation cavity 30 increases, causing the expansion layer 31 to expand, thereby causing the expansion layer 31 to overflow 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 dislocated ends of the guide rails 14, so that when the lifting mechanism passes through the dislocation point of the two guide rails 14, it first contacts and buffers the expansion layer 31, reducing the hard collision between the lifting mechanism and the guide rails 14, which is beneficial to improving the service life of the lifting mechanism and the guide rails 14, and can reduce the noise during the operation of the lifting mechanism.
