Description

Technical Field

[0001] This utility model relates to the technical field of shaft component disassembly devices, specifically to a shaft component disassembly device. Background Technology

[0002] Currently, rotating shafts typically have a sleeve component fitted onto them. This sleeve component often needs to be removed from the rotating shaft for maintenance, and a puller is generally used for removal. Existing Chinese patent document with application number 202321280193.1 discloses a two-jaw puller with adjustable puller screw length and spacing. It includes a crossbeam, two puller screws, and a top-pressing screw. A threaded hole is provided in the middle of the crossbeam, and the top-pressing screw is screwed into the threaded hole. A rotating mechanism is provided at the upper end of the top-pressing screw. Two strip-shaped holes are provided on the crossbeam, located on opposite sides of the threaded hole. A puller screw is installed in each strip-shaped hole, allowing the puller screw to move within the strip-shaped hole. Each puller screw is equipped with an adjusting nut and a locking nut, located above and below the crossbeam, respectively. A hook is provided at the lower end of each puller screw. This two-jaw puller with adjustable puller screw length and spacing has the following shortcomings:

[0003] 1) During operation, it is necessary to hold the crossbeam by hand or with the help of other equipment to straighten it, which is inconvenient.

[0004] 2) Pressing the rotating shaft by rotating the pressing screw has two drawbacks. First, the rotation operation is inconvenient. Second, the rotating shaft is easily worn due to friction with the screw during rotation. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a simple and convenient disassembly device for the sleeve component that avoids wear on the rotating shaft.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A sleeve shaft component disassembly device includes a movable frame, a lifting seat, a telescopic top support component, and two tie rods. The lifting seat is elliptically mounted on the movable frame, and the movable frame is provided with a lifting adjustment mechanism for driving the lifting seat to adjust its height. One end of each of the two tie rods is fixed to the lifting seat, and the other end protrudes to the same side of the lifting seat. Each tie rod has an inwardly protruding pulling part at its protruding end. The telescopic top support component is located on the lifting seat and between the two tie rods. The telescopic end of the telescopic top support component has a top support part for supporting the rotating shaft when the pulling part pulls the sleeve shaft component.

[0008] As a further improvement to the above technical solution:

[0009] The two tie rods are parallel.

[0010] A reinforcing assembly connects the two tie rods.

[0011] The reinforcing component includes an arc-shaped rod, with connecting rods at both ends. Each connecting rod has a sleeve, which is slidably fitted onto a corresponding pull rod.

[0012] The socket includes an upper plate and a lower plate. The upper plate is fixed on the corresponding connecting rod, and the outer end of the lower plate is slidably connected to the upper plate. A groove is formed between the upper plate and the lower plate, and a locking member is provided for locking the two together. The groove is slidably sleeved on the corresponding pull rod.

[0013] The telescopic support component is detachably connected to the lifting seat.

[0014] The telescopic support component is a jack.

[0015] The lifting adjustment mechanism includes a lead screw and a rotary handle. The lead screw is rotatably mounted on the movable frame, passes through the lifting seat and is threadedly connected to the lifting seat, and the rotary handle is located at the top of the lead screw.

[0016] The pull rod is provided with a plurality of fixing holes arranged at intervals along the length direction, and a fixing member is inserted through at least one of the fixing holes. The fixing member is fixedly connected to the movable frame and presses the pull rod.

[0017] The front end of the mobile frame is hinged with a traction rod and a locking part for securing the traction rod, and the bottom of the mobile frame is equipped with casters.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This utility model discloses a sleeve component disassembly device. In use, the device is moved to the corresponding position of the sleeve component to be disassembled. The lifting adjustment mechanism adjusts the lifting seat so that the pulling parts of the two pull rods hook onto both sides of the sleeve component. Then, the telescopic support component extends, causing the support part to push against the rotating shaft. Under the combined action of the telescopic support component extending and the pulling part pulling, the sleeve component can be pulled off the rotating shaft. This sleeve component disassembly device is simple and convenient because, on the one hand, the pulling part hooks onto the side face of the sleeve component simply by moving the frame into position and adjusting the lifting seat, eliminating the need for hand-holding or other equipment for support during the pulling operation. On the other hand, the telescopic support component extends to support the rotating shaft, facilitating operation and preventing friction and wear on the rotating shaft. Attached Figure Description

[0032] Figures 1 to 6 This invention illustrates an embodiment of the sleeve shaft component disassembly device. The sleeve shaft component disassembly device of this embodiment includes a movable frame 1, a lifting seat 2, a telescopic top support component 3, and two pull rods 4. The lifting seat 2 is flexibly mounted on the movable frame 1. The movable frame 1 is provided with a lifting adjustment mechanism 5 for driving the lifting seat 2 to adjust its height. One end of each of the two pull rods 4 is fixed on the lifting seat 2, and the other end protrudes to the same side of the lifting seat 2. Each pull rod 4 has a pull portion 41 protruding inward at its protruding end. The telescopic top support component 3 is mounted on the lifting seat 2 and located between the two pull rods 4. The telescopic end of the telescopic top support component 3 is provided with a top support portion 31 for supporting the rotating shaft 6 when the pull portion 41 pulls the sleeve shaft component 61.

[0033] When using, such as Figure 6 As shown, the disassembly device for this sleeve shaft component is moved to the corresponding position of the sleeve shaft component 61 to be disassembled. The lifting adjustment mechanism 5 is used to adjust the lifting seat 2 so that the pulling parts 41 of the two pull rods 4 are hooked onto both sides of the sleeve shaft component 61. Then, the telescopic support component 3 extends to support the rotating shaft 6. Under the extension and support of the telescopic support component 3 and the pulling action of the pulling part 41, the sleeve shaft component 61 can be pulled out from the rotating shaft 6. This sleeve shaft component disassembly device has two advantages. First, the pulling part 41 can be hooked onto the side end face of the sleeve shaft component 61 by moving the moving frame 1 into position and adjusting the lifting seat 2. During the pulling operation, it is not necessary to hold it or use other equipment to straighten it, making the operation simple and convenient. Second, the extension of the telescopic support component 3 can support the rotating shaft 6, which is convenient to operate and avoids friction with the rotating shaft 6 and wear.

[0034] Furthermore, in this embodiment, the two tie rods 4 are parallel.

[0035] Furthermore, in this embodiment, a reinforcing component 7 is connected between the two pull rods 4. The reinforcing component 7 is connected to the overhanging ends of the two pull rods 4 to prevent the two pull rods 4 from being pushed outward during the pulling process.

[0036] Furthermore, such as Figures 1 to 4As shown, in this embodiment, the reinforcing component 7 includes an arc-shaped rod 71, with connecting rods 72 at both ends of the arc-shaped rod 71. Each connecting rod 72 has a sleeve 73, which is slidably fitted onto the corresponding pull rod 4. In this way, the reinforcing component 7 can be slidably adjusted along the pull rod 4.

[0037] Furthermore, such as Figure 2 and Figure 4 As shown, in this embodiment, the sleeve 73 includes an upper plate 731 and a lower plate 732. The upper plate 731 is fixed on the corresponding connecting rod 72, and the outer end of the lower plate 732 is slidably connected to the upper plate 731. A groove 733 is formed between the upper plate 731 and the lower plate 732, and a locking member 734 for locking the two is provided. The groove 733 is slidably sleeved on the corresponding pull rod 4. The outer end of the lower plate 732 is slidably connected to the upper plate 731. The sliding direction of the lower plate 732 relative to the upper plate 731 is the interval direction of the two pull rods 4. Thus, after releasing the locking effect of the locking member 734, the lower plate 732 is slid outward, so that the lower plate 732 slides from the lower side of the pull rod 4 to the outside of the pull rod 4, and the reinforcing component 7 can be disassembled. Preferably, the upper plate 731 is provided with a guide groove, the length direction of which is parallel to the spacing direction of the two pull rods 4. The outer end of the lower plate 732 is provided with a post, which is slidably inserted into the guide groove. The locking member 734 is a locking bolt, which passes through the guide groove. Under the locking action, the locking member 734 clamps the upper plate 731 and the lower plate 732 onto the pull rod 4. By removing the locking member 734, the lower plate 732 can be disassembled from the upper plate 731.

[0038] Furthermore, in this embodiment, the telescopic support component 3 is detachably connected to the lifting seat 2, such as by screws, making assembly and disassembly convenient. Preferably, the telescopic support component 3 is a jack.

[0039] Furthermore, such as Figure 1 and Figure 5 As shown, in this embodiment, the lifting adjustment mechanism 5 includes a lead screw 51 and a rotary handle 52. The lead screw 51 is rotatably mounted on the movable frame 1, passes through the lifting seat 2, and is threadedly connected to the lifting seat 2. The rotary handle 52 is located at the top of the lead screw 51. Turning the rotary handle 52 drives the lead screw 51 to rotate, and the lead screw 51 drives the lifting seat 2 to adjust its height through the threaded connection. The structure is simple and the adjustment is convenient.

[0040] Furthermore, such as Figure 3 As shown, in this embodiment, the pull rod 4 is provided with a plurality of fixing holes 42 arranged at intervals along the length direction, and a fixing member 8 is inserted through at least one fixing hole 42. The fixing member 8 is fixedly connected to the movable frame 1 and presses the pull rod 4. On the one hand, the overhang length of the pull rod 4 can be adjusted; on the other hand, the pull rod 4 is fixed by the fixing member 8, making it easy to assemble and disassemble. Preferably, the fixing member 8 is a fixing bolt.

[0041] Furthermore, in this embodiment, the front end of the movable frame 1 is hinged with a traction rod 9 and a locking part 12 for securing the traction rod 9, and the bottom of the movable frame 1 is provided with a moving wheel 11. The movable frame 1 is pulled by the traction rod 9, and the traction rod 9 is fixed by being locked in the locking part 12. Preferably, the movable frame 1 may include a U-shaped base and a vertical rod, the bottom of the vertical rod is fixed to the middle part of the middle wall of the U-shaped base, the lead screw 51 is rotatably mounted on the vertical rod, the lifting seat 2 is slidably sleeved on the vertical rod, the moving wheel 11 is located at the bottom of the U-shaped base, the traction rod 9 is hinged to the middle wall of the U-shaped base, and the pull rod 4 extends out toward the opening of the U-shaped base.
