Description

Technical Field

[0001] This application relates to the field of elevator maintenance technology, and in particular to a traction sheave disassembly device. Background Technology

[0002] A traction sheave is a wheel used to change the direction of motion of an object, widely used in construction, engineering equipment, and elevators. Its core function is to transmit power or directional movement of objects through cooperation with transmission components such as steel wire ropes. In elevator systems, the traction sheave is one of the core components of the traction machine, directly affecting the elevator's operational stability and safety.

[0003] During the use of traction sheaves, disassembling the traction sheave is an essential step when maintenance or replacement is required. Traditional traction sheave disassembly methods require specialized disassembly tools depending on the sheave model. A top block is placed against the traction machine shaft end, and a fixing plate is threaded to the traction sheave end face with bolts. The traction sheave is then pushed out by operating the top block. This method has several problems, such as being cumbersome, time-consuming, and some disassembly tools (such as simple pullers) having structural stability issues, leading to a "easy dislodgement after being secured" phenomenon. This could result in the traction sheave falling off and injuring people or damaging equipment, thus affecting work efficiency. Utility Model Content

[0004] To enhance the stability of disassembly tools and improve the ease of operation, this application provides a traction sheave disassembly device.

[0005] The traction sheave disassembly device provided in this application adopts the following technical solution:

[0006] A traction sheave disassembly device includes a fixed frame, a connecting screw, a top cylinder structure, positioning components, and a clamping structure. The fixed frame is disposed above the shaft end of the traction sheave. A plurality of positioning components and clamping structures are evenly arranged circumferentially on the fixed frame. The clamping structures are respectively disposed circumferentially on the traction sheave and grip the edge of the traction sheave. The positioning components pass through the fixed frame and are threadedly connected to the clamping structures. One end of the top cylinder structure abuts against the shaft end of the traction sheave, and the other end abuts against the center of the fixed frame. A first connecting screw hole is opened in the center of the fixed frame, and a second connecting screw hole is opened in the top cylinder structure near the fixed frame. The connecting screw passes through the first connecting screw hole and the second connecting screw hole in sequence and abuts against the shaft end of the traction sheave.

[0007] By adopting the above technical solution, the fixed frame serves as a support mechanism and is positioned directly above the traction wheel shaft end. The positioning components located around the fixed frame firmly fix the fixed frame, making it less prone to shaking. The clamping structures clamp the protruding edges of the traction wheel from different directions and are fixed by the positioning components. The top cylinder structure is placed between the fixed frame and the traction wheel and is abutted by both the fixed frame and the traction wheel. The connecting screws pass through connecting screw hole one and connecting screw hole two in sequence and abut against the traction wheel shaft end. When the operator tightens the connecting screw using a torque wrench or similar tool, the connecting screw tightly abuts against the traction sheave shaft surface. Since the connecting screw is sequentially threaded to the center of the fixed frame and the top cylinder structure, the fixed frame and top cylinder structure move away from the traction sheave when the connecting screw rotates. Because the fixed frame is fixedly connected to several positioning components, which in turn are fixedly connected to the clamping structures, and these clamping structures clamp the edges of the traction sheave, the traction sheave moves in the same direction, thus allowing the traction sheave to be replaced to be removed from the bushing. This achieves stable disassembly of the traction sheave, reducing the likelihood of it coming loose after being clamped. The operation is convenient, quick, and saves time and effort. Furthermore, the disassembly fixture used in this application is compact, can be packed in a small box for easy carrying, and can be disassembled directly on-site, saving costs.

[0008] Optionally, the fixed frame includes horizontal bars and vertical bars, which intersect and overlap to form a cross frame. Each horizontal bar and vertical bar has a connecting screw hole at its center. The connecting screw is threaded to the horizontal bar and vertical bar through the connecting screw hole. Each horizontal bar and vertical bar has a positioning screw hole at both ends, and a positioning component is inserted into each positioning screw hole.

[0009] By adopting the above technical solution, the fixing frame is designed with two structures: horizontal bars and vertical bars. In use, the horizontal and vertical bars are interlocked to form a cross frame. Under the fixing action of the positioning components, a stable structure is formed, allowing the connecting screw to move directly along its own axis during rotation, reducing offset. Furthermore, it reduces the buffering force on the central part of the fixing frame. When not in use, the horizontal and vertical bars can be disassembled and stored separately, reducing storage space and facilitating portability.

[0010] Optionally, the positioning component includes a positioning screw and a fixing member. The positioning screw passes through a positioning screw hole and is threadedly connected to a clamping structure. The fixing member is disposed on two opposite sides of the positioning screw hole and is threadedly connected to the positioning screw.

[0011] By adopting the above technical solution, after the positioning screw passes through the positioning screw hole, it is fixed on the fixed frame by the positioning parts on both sides of the horizontal and vertical rods. The head of the positioning screw is threaded to the clamping structure, thereby realizing the fixed connection between the positioning screws at both ends and the clamping structure and the fixed frame respectively.

[0012] Optionally, the clamping structure includes a clamping member, a clamping screw, a first fixing member, a second fixing member, and a fixing bolt. The upper surface of the clamping member has a "C"-shaped groove, which engages with the protruding edge of the traction sheave. The two walls of the "C"-shaped groove are of different heights, with the higher wall positioned within the inner ring of the protruding edge of the traction sheave and the lower wall positioned within the outer ring. A clamping screw hole is provided on the side of the higher wall, through which the clamping screw passes and abuts against the inner ring of the protruding edge of the traction sheave. The first and second fixing members are stacked on the upper surface of the lower wall, each with a fixing hole. A fixing screw hole is also provided on the upper surface of the lower wall, through which the fixing bolt passes sequentially. The bolt is threadedly connected to the clamping member via the fixing hole and the fixing screw hole. Both the first and second fixing members abut against the outer ring of the protruding edge of the traction sheave.

[0013] By adopting the above technical solution, the "C"-shaped groove of the clamping component is fastened to the protruding edge of the traction wheel. A tightening screw hole is opened on the high groove wall side, and the tightening screw passes through the tightening screw hole and abuts against the inner ring of the protruding edge of the traction wheel. On the low groove wall side, according to the alternating protrusion and groove structure of the outer ring of the protruding edge of the traction wheel, the first fixing component and the second fixing component are precisely set. The first fixing component and the second fixing component are closely attached to and clamped with the outer ring of the protruding edge of the traction wheel, thereby realizing that the clamping component firmly grips the protruding edge of the traction wheel on both sides, reducing the occurrence of detachment.

[0014] Optionally, the bottom of the "C"-shaped groove is provided with a second positioning screw hole, and the positioning screw passes through the second positioning screw hole and abuts against the protruding edge of the traction wheel.

[0015] By adopting the above technical solution, the positioning screw passes through the second positioning screw hole and abuts against the protruding edge of the traction wheel, which not only realizes the threaded fixed connection between the positioning screw and the clamping part, but also realizes the clamping part to be further clamped to the traction wheel, thereby enhancing the gripping force of the clamping part.

[0016] Optionally, both the first and second fixing members have a crescent-shaped structure and are bent toward the "C"-shaped groove. The first fixing member is placed below the second fixing member, and the first and second fixing members have a trapezoidal structure at the end facing the "C"-shaped groove.

[0017] By adopting the above technical solution, the crescent-shaped structure of the first and second fixing members allows the first and second fixing members to perfectly match the curvature of the outer ring of the protruding edge of the traction wheel; and the first and second fixing members form a trapezoidal structure, that is, the first fixing member protrudes outward relative to the second fixing member. This design is also to make the first and second fixing members fit tightly with the outer ring of the protruding edge of the traction wheel, thereby enhancing the gripping stability of the clamping member.

[0018] Optionally, the top cylinder structure includes a cylinder body, a sleeve, and a guide cylinder. One end of the cylinder body abuts against the shaft end of the traction wheel, and the other end abuts against the center part of the fixed frame. The end of the cylinder body near the traction wheel is hollow, and the part near the fixed frame is solid. The solid part of the cylinder body has two connecting screw holes along the axial direction of the cylinder body for the connecting screw to pass through. The sleeve is sleeved on the end of the cylinder body near the fixed frame, and the guide cylinder is embedded inside the cylinder body at the end near the traction wheel.

[0019] By adopting the above technical solution, the cylinder is solid at one end and hollow at the other end. This makes the cylinder more robust and extends the contact area between the connecting screw and the second connecting screw hole, maintaining a stable connection between the connecting screw and the cylinder. The sleeve fitted onto the cylinder prevents it from being squeezed, deformed, or damaged, thus providing protection. The guide cylinder is embedded inside the cylinder and connects with the solid part of the cylinder. This reduces the gap between the connecting screw and the cylinder, providing guidance and strengthening the hardness of the hollow part of the cylinder. It also facilitates disassembly or replacement, making maintenance convenient.

[0020] Optionally, a fixing plate is fixedly provided on the cylinder near the traction wheel shaft end, and the fixing plate is attached to the traction wheel shaft end and fixed by bolts.

[0021] By adopting the above technical solution, a fixing plate is fixedly installed at the end of the cylinder near the traction sheave shaft, which increases the contact area between the cylinder and the traction sheave, allowing the traction sheave to be removed stably. The fixing plate is fixed to the traction sheave with bolts, realizing a fixed connection between the cylinder and the traction sheave, solving the problem of unstable contact between the cylinder and the traction sheave, thereby achieving stable disassembly of the traction sheave.

[0022] Optionally, a fixed shaft is placed inside the guide cylinder, and the fixed shaft is fixedly connected to the axis of the traction wheel by bolts. A boss is provided at one end of the guide cylinder near the traction wheel. The diameter of the boss is smaller than the diameter of the fixed shaft. The fixed shaft is placed at one end of the guide cylinder near the traction wheel and abuts against the boss.

[0023] By adopting the above technical solution, a fixed shaft is placed inside the guide cylinder. The fixed shaft serves as an extension shaft of the traction wheel shaft and is fixedly connected to the traction wheel shaft. The connecting screw abuts against the fixed shaft by rotation, thereby applying force to the traction wheel shaft. This avoids the connecting screw directly contacting the traction wheel and reduces wear on the traction wheel shaft surface. The design of the boss prevents the fixed shaft from entering deep into the guide cylinder.

[0024] Optionally, the top cylinder structure is a hydraulic jack, one end of which is interference-fitted with the traction wheel shaft end, and the other end abuts against the center of the fixed frame.

[0025] By adopting the above technical solution, the hydraulic jack is electrically controlled and applies pressure to the traction wheel shaft end to push out the traction wheel. This setting is more time-saving, labor-saving, convenient and quick, and reduces the tediousness of manually pushing out the traction wheel.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By placing the fixed frame directly above the traction sheave shaft end, the positioning components located around the fixed frame firmly secure it, preventing it from wobbling. Clamping structures clamp the protruding edges of the traction sheave from different directions and are fixed by the positioning components. The top cylinder structure is placed between the fixed frame and the traction sheave, and is abutted by both. The connecting screws pass through connecting screw holes one and two in sequence and abut against the traction sheave shaft end. When the operator tightens the connecting screws using a torque wrench or similar tool, the connecting screws abut tightly against the traction sheave shaft surface. The fixed frame and top cylinder structure move away from the traction sheave, and the traction sheave moves in the same direction, allowing the traction sheave to be replaced to be removed from the bushing. This achieves stable disassembly of the traction sheave, reduces the occurrence of clamping and then dislodging, and makes the operation convenient, quick, and time-saving.

[0028] 2. By fastening the "C"-shaped groove of the clamping component to the protruding edge of the traction wheel, a tightening screw hole is opened on the high groove wall side, and the tightening screw passes through the tightening screw hole and abuts against the inner ring of the protruding edge of the traction wheel; on the low groove wall side, according to the alternating protrusion and groove structure of the outer ring of the protruding edge of the traction wheel, the first fixing component and the second fixing component are precisely set. The first fixing component and the second fixing component are tightly fitted and clamped to the outer ring of the protruding edge of the traction wheel, thereby realizing that the clamping component firmly grips the protruding edge of the traction wheel on both sides, reducing the occurrence of detachment.

[0029] 3. By designing one end of the cylinder to be solid and the other end to be hollow, the cylinder can be made more robust, and the contact area between the connecting screw and the connecting screw hole can be extended, maintaining the stability of the connecting screw and the cylinder. The sleeve fitted onto the cylinder can prevent the cylinder from being squeezed, deformed or damaged, thus providing protection. The guide cylinder is embedded inside the cylinder and connects with the solid part of the cylinder. This reduces the gap between the connecting screw and the cylinder, providing guidance, and also strengthens the hardness of the hollow part of the cylinder. In addition, it facilitates disassembly or replacement, making maintenance convenient. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Example 1

Figure 1 A traction sheave disassembly device includes a fixed frame 1, a connecting screw 2, a top cylinder structure 3, positioning components 4, and clamping structures 5. The fixed frame 1 is positioned directly above the shaft end of the traction sheave. A plurality of positioning components 4 and clamping structures 5 are evenly arranged around the circumference of the fixed frame 1. In this application, the number of positioning components 4 and clamping structures 5 is the same, and their positions correspond. The number of positioning components 4 and clamping structures 5 can be determined according to actual conditions; in this embodiment, four positioning components 4 and clamping structures 5 are selected. The four clamping structures 5 are evenly arranged around the circumference of the traction sheave and grip the edge of the traction sheave. The four positioning components 4 pass through the fixed frame 1 from different directions and are threadedly connected to their corresponding clamping structures 5. The top cylinder structure 3 is also located directly above the traction wheel shaft end. The top cylinder structure 3 is parallel to the positioning component 4. One end of the top cylinder structure 3 abuts against the traction wheel shaft end, and the other end abuts against the center of the fixed frame 1. A connecting screw hole 121 is provided in the center of the fixed frame 1. A connecting screw hole 311 is provided at the end of the top cylinder structure 3 near the fixed frame 1. The connecting screw 2 passes through the connecting screw hole 121 and the connecting screw hole 311 in sequence and abuts against the traction wheel shaft end.

[0040] Reference Figure 1 The fixed frame 1 includes a horizontal bar 11 and a vertical bar 12. The horizontal bar 11 and the vertical bar 12 intersect and overlap to form a cross frame. The center of the horizontal bar 11 and the vertical bar 12 are provided with connecting screw holes 121. The two connecting screw holes 121 overlap. The connecting screw 2 passes through the connecting screw holes 121 to achieve threaded connection with the horizontal bar 11 and the vertical bar 12. The two ends of the horizontal bar 11 and the vertical bar 12 are provided with positioning screw holes 122. Positioning components 4 pass through the positioning screw holes 122. The positioning components 4 are threadedly fixedly connected to the horizontal bar 11 or the vertical bar 12.

[0041] The positioning component 4 includes a positioning screw 41 and a fixing member 42. The positioning screw 41 passes through the positioning screw hole 122 and is threadedly connected to the clamping structure 5. There are two sets of fixing members 42, which are respectively set on opposite sides of the positioning screw hole 122 and threadedly connected to the positioning screw 41.

[0042] In this application, all positioning screw holes 122 are oblong holes. The positioning screw 41 can move left and right or up and down within the oblong hole, thereby allowing the positioning assembly to be adjusted horizontally according to the position and size of the protruding edge of the traction sheave, so that the clamping structure firmly clamps the traction sheave. The fixing component 42 includes a washer 421 and a nut 422. The washer 421 fits into the positioning screw hole 122, and the nut 422 tightens the washer 421.

[0043] Reference Figure 2 and Figure 3 The clamping structure 5 includes a clamping member 51, a clamping screw 52, ​​a first fixing member 53, a second fixing member 54, and a fixing bolt 55. The upper surface of the clamping member 51 is provided with a "C" shaped groove 511. The width of the "C" shaped groove 511 is adapted to the width of the protruding edge of the traction wheel. The "C" shaped groove 511 is engaged with the protruding edge of the traction wheel. The two groove walls of the "C" shaped groove 511 are of different heights. The higher groove wall is placed in the inner ring of the protruding edge of the traction wheel, and the lower groove wall is placed in the outer ring of the protruding edge of the traction wheel. A clamping screw hole 512 is provided on the side of the higher groove wall. The clamping screw 52 passes through the clamping screw hole 512 and abuts against the inner ring of the protruding edge of the traction wheel. The first fixing member 53 and the second fixing member 54 are stacked on the upper surface of the low groove wall. Each of the first fixing member 53 and the second fixing member 54 has a set of fixing holes 541, and the two sets of fixing holes 541 correspond to each other. A set of fixing screw holes 513 are correspondingly opened on the upper surface of the low groove wall. Two fixing bolts 55 pass through the fixing holes 541 and the fixing screw holes 513 in sequence and are threadedly connected to the clamping member 51. The ends of the first fixing member 53 and the second fixing member 54 near the traction sheave are both abutted against the outer ring of the protruding edge of the traction sheave.

[0044] Both the first fixing member 53 and the second fixing member 54 have a crescent-shaped structure and are bent toward the "C"-shaped groove 511. The first fixing member 53 is placed below the second fixing member 54. The ends of the first fixing member 53 and the second fixing member 54 away from the traction sheave are neatly overlapped. The ends of the first fixing member 53 and the second fixing member 54 facing the "C"-shaped groove 511 have a trapezoidal structure, that is, the first fixing member 53 protrudes outward relative to the second fixing member 54, so that the first fixing member 53 can better penetrate into the groove of the outer ring of the protruding edge of the traction sheave to achieve the purpose of firm gripping.

[0045] The bottom of the “C”-shaped groove 511 has a positioning screw hole 514. The positioning screw 41 passes through the positioning screw hole 514 to achieve threaded connection with the clamping part 51 and to achieve abutment between the positioning screw 41 and the protruding edge of the traction wheel.

[0046] Reference Figure 4 and Figure 5 The top cylinder structure 3 includes a cylinder 31, a sleeve 32, and a guide cylinder 33. One end of the cylinder 31 abuts against the shaft end of the traction sheave, and the other end abuts against the center of the fixed frame 1. The end of the cylinder 31 near the traction sheave is hollow, and the end near the fixed frame 1 is solid. The solid part of the cylinder 31 has a connecting screw hole 311 along the axial direction of the cylinder 31 for the connecting screw 2 to pass through. The sleeve 32 is fitted onto the end of the cylinder 31 near the fixed frame 1. A bottom is fixedly provided on the end of the sleeve 32 near the fixed frame 1, and a corresponding through hole for the connecting screw 2 to pass through is provided on the bottom. The sleeve 32 fits onto the cylinder 31 to protect it and reduce wear on the cylinder 31. The guide cylinder 33 is embedded inside the cylinder 31 near the traction sheave. The guide cylinder 33 connects with the solid part of the cylinder 31, which enhances the rigidity of the cylinder 31 and provides guidance.

[0047] A fixed shaft 35 is placed inside the guide cylinder 33. Several connecting holes are opened on the fixed shaft along its circumference. The fixed shaft 35 is fixedly connected to the shaft of the traction sheave by bolts. A boss 331 is provided at the end of the guide cylinder 33 near the traction sheave. The fixed shaft 35 abuts against the boss 331. The diameter of the boss 331 is smaller than the diameter of the fixed shaft 35, so that the fixed shaft 35 is not easy to fall into the deepest part of the guide cylinder 33, and the fixed shaft 35 is always placed at the end of the guide cylinder 33 near the traction sheave.

[0048] A fixing plate 34 is fixedly installed on the cylinder 31 near the end of the traction sheave shaft. The fixing plate 34 is arranged around the edge of the cylinder 31 and is attached to the end of the traction sheave shaft and fixed by bolts.

[0049] The implementation principle of the traction wheel disassembly device in Embodiment 1 of this application is as follows:

[0050] In use, take all disassembly tools out of the toolbox, assemble the clamping structure 5 and the top cylinder structure 3 in sequence. After all are assembled, clamp the four clamping structures 5 evenly on the protruding edge of the traction wheel, and then fix the fixed shaft to the traction wheel shaft with bolts. Place the top cylinder structure 3 on the traction wheel shaft end, and fix the fixed plate 34 to the traction wheel shaft surface with bolts. Then, overlap the horizontal bar 11 and the vertical bar 12 and abut against the end of the top cylinder structure 3 away from the traction wheel. The connecting screw 2 passes through the connecting screw hole 121 and the connecting screw hole 211 in sequence. The four positioning components 4 pass through the positioning screw holes 122 at both ends of the horizontal bar 11 and the vertical bar 12 respectively. During the insertion process, the fixing component 42 is placed on the two opposite sides of the positioning screw hole 122. Then, the positioning screw 41 passes through the positioning screw hole 2514 and is threadedly fixed to the clamping component 51. Then, readjust the fixing component 42 to fix the positioning screw 41. Finally, tighten the connecting screw 2 so that it is tightly abutted against the fixed shaft 35. With the help of a wrench or other tools, tighten the connecting screw 2 again in the same direction. At this time, the fixed frame 1 will drive the traction wheel to slowly move away from the axis of the traction wheel, thereby removing the traction wheel from the axis.

[0052] Reference Figure 6 A traction sheave disassembly device includes a fixed frame 1, a top cylinder structure 3, positioning components 4, and clamping structures 5. The fixed frame 1 is positioned directly above the shaft end of the traction sheave. A plurality of positioning components 4 and clamping structures 5 are evenly arranged circumferentially on the fixed frame 1. In this application, the number of positioning components 4 and clamping structures 5 is the same, and can be two, three, four, six, or even more, depending on the site conditions. The positioning components 4 and clamping structures 5 are positioned correspondingly. The plurality of clamping structures 5 are evenly arranged circumferentially on the traction sheave and grip the edge of the traction sheave. The plurality of positioning components 4 pass through the fixed frame 1 from different directions and are threadedly connected to their corresponding clamping structures 5.

[0053] In this application, the top cylinder structure 3 is a hydraulic jack, which is parallel to the positioning component 4. One end of the hydraulic jack is interference-fitted with the traction wheel shaft end, and the other end abuts against the center of the fixed frame 1.

[0054] Reference Figure 6 The fixed frame 1 includes a longitudinal rod 12, and both ends of the longitudinal rod 12 are provided with positioning screw holes 122. Positioning components 4 are inserted into the positioning screw holes 122 and are threadedly fixed to the longitudinal rod 12.

There are two sets of fixing members 42, which are respectively set on opposite sides of the positioning screw hole 122 and threadedly connected to the positioning screw 41.

[0056] The fastener 42 includes a washer 421 and a nut 422. The washer 421 fits into the positioning screw hole 122, and the nut 422 presses the washer 421 against the hole.

[0057] The implementation principle of the traction wheel disassembly device in Embodiment 2 of this application is as follows:

[0058] In use, remove all disassembly tools from the toolbox, assemble the clamping structures 5 one by one, and after all are assembled, evenly clamp the clamping structures 5 onto the protruding edges of the traction sheave. Then place the hydraulic jack on the shaft end of the traction sheave, and connect the extension part of the hydraulic jack to the shaft end of the traction sheave with an interference fit. Then, abut the longitudinal rod 12 against the base of the hydraulic jack. Pass the positioning components 4 through the positioning screw holes 122 at both ends of the longitudinal rod 12. During the insertion process, the fixing parts 42 are placed on the two opposite sides of the positioning screw holes 122. Then, pass the positioning screw 41 through the positioning screw hole 514 and thread it to the clamping parts 51. Then, readjust the fixing parts 42 to fix the positioning screw 41. Start the hydraulic jack. The extension part of the hydraulic jack moves forward and pushes the traction sheave outward. The traction sheave will gradually move away from the axis of the traction sheave along with the fixing frame 1, thereby removing the traction sheave from the axis.

[0059] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
