The first fastening bolt, the second fastening bolt and the third fastening bolt are all composed of hexagonal head bolts, spring washers, hexagonal nuts and flat washers. The bottom of the first base beam and the second base beam are provided with a first fixing screw hole and a second fixing screw hole.

[0004] The guide wheel frame mentioned in the above patent has some obvious shortcomings in actual use. The device uses bolts to fix the guide wheel, which makes it inconvenient to install or disassemble the guide wheel, affecting the maintenance or replacement of the guide wheel. Therefore, we need to propose a hanger guide wheel installation module. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hanger guide wheel installation module, including a support frame, two sets of crossbeams are provided on the top of the support frame, a guide wheel is provided between the two sets of crossbeams, the guide wheel is connected to a rotating shaft, and disassembly and assembly components for installing or removing the rotating shaft are provided between the two ends of the rotating shaft and the top of the two sets of crossbeams.

[0007] The assembly and disassembly assembly includes two sets of mounting slots opened on the top of the two sets of crossbeams and two sets of bearing seats adapted to be connected to both ends of the rotating shaft. The lower end of the bearing seat is adapted to be disposed inside the mounting slot. A limiting mechanism is provided between the bearing seat and the crossbeam, and the bearing seat is installed in the inner cavity of the mounting slot through the limiting mechanism.

[0008] Preferably, the limiting mechanism includes a limiting cavity opened at one end of the crossbeam, a limiting block is slidably connected to one end of the limiting cavity, and a threaded rod is rotatably connected to the other end of the limiting cavity.

[0009] Preferably, the limiting mechanism further includes a limiting hole that extends through one end of the bearing seat, the interior of the limiting hole being adapted to the limiting block, and the limiting block being inserted into the inner cavity of the limiting hole.

[0010] Preferably, the drive module includes a drive rod rotatably connected to one side of the support frame, a first pulley is fixedly mounted on the surface of the drive rod, and a belt is adapted to be connected to the surface of the first pulley.

[0011] Preferably, the drive module further includes two sets of second pulleys fixedly installed at one end of the two sets of threaded rods and located at corresponding positions at one end of the two sets of crossbeams. The surfaces of the second pulleys are adapted to the belt, and the two sets of second pulleys are connected to the first pulleys through the belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a mounting groove, bearing housing, and limiting mechanism to assemble the bearing housing and the rotating shaft with the guide wheel already installed into an independent module. The lower end of the bearing housing is then aligned with the mounting groove at the top of the crossbeam and lowered vertically to the bottom of the groove. The limiting mechanism then confines the bearing housing within the inner cavity of the mounting groove, allowing for the installation of the guide wheel. Simultaneously, the flexibility of the guide wheel's rotation and the absence of gaps between the bearing housing and the inner cavity of the mounting groove can be manually checked. Conversely, if any gaps are found, the guide wheel can be removed from the top of the crossbeam, enabling installation or removal of the guide wheel. This allows workers to inspect the guide wheel, rotating shaft, or bearing housing individually without disassembling the entire crossbeam or support frame. This solves the problems of low assembly / disassembly efficiency, poor positioning accuracy, and high maintenance costs associated with traditional guide wheel installation modules. It facilitates the inspection and replacement of the guide wheel, avoids component failure due to maintenance delays, and improves the safety of the device.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a hanger guide wheel installation module, including a support frame 1, two sets of crossbeams 2 are provided on the top of the support frame 1, guide wheels 3 are provided between the two sets of crossbeams 2, the guide wheels 3 are connected to a rotating shaft 4, and disassembly and assembly components for installing or removing the rotating shaft 4 are provided between the two ends of the rotating shaft 4 and the top of the two sets of crossbeams 2.

[0025] Preferably, the assembly and disassembly components include: mounting grooves 5, bearing seats 6, and limiting mechanisms. Two sets of mounting grooves 5 are opened on the top of two sets of crossbeams 2. Two sets of bearing seats 6 are adapted to be connected to both ends of the rotating shaft 4. The lower end of the bearing seat 6 is adapted to be installed in the interior of the mounting groove 5. A limiting mechanism is provided between the bearing seat 6 and the crossbeam 2, and the bearing seat 6 is installed in the inner cavity of the mounting groove 5 through the limiting mechanism.

[0026] Specifically, through the coordinated use of the mounting groove 5, bearing seat 6, and limiting mechanism, the bearing seat 6 and the rotating shaft 4 with the guide wheel 3 already installed are assembled into an independent module. Then, the lower end of the bearing seat 6 is aligned with the mounting groove 5 at the top of the crossbeam 2 and lowered vertically to the bottom of the groove. The limiting mechanism then confines the bearing seat 6 within the inner cavity of the mounting groove 5, allowing the guide wheel 3 to be installed. At the same time, the flexibility of the guide wheel 3's rotation and the absence of gaps between the bearing seat 6 and the inner cavity of the mounting groove 5 are manually checked. If any gaps are found, the guide wheel 3 can be removed from the top of the crossbeam 2, allowing for installation or removal of the guide wheel 3. This enables workers to inspect the guide wheel 3, rotating shaft 4, or bearing seat 6 individually without disassembling the entire crossbeam 2 or support frame 1. This solves the problems of low disassembly and assembly efficiency, poor positioning accuracy, and high maintenance costs associated with traditional guide wheel installation modules. It facilitates the inspection and replacement of the guide wheel 3, avoids component failure due to maintenance delays, and improves the safety of the device.

[0027] Preferably, the limiting mechanism includes: a limiting cavity 7, a limiting block 8, a threaded rod 9, and a limiting hole 10. The limiting cavity 7 is located at one end inside the crossbeam 2. The limiting block 8 is slidably connected to one end of the limiting cavity 7, and the threaded rod 9 is rotatably connected to the other end of the limiting cavity 7. One end of the surface of the threaded rod 9 is threadedly connected to the inner cavity of the limiting block 8, and the limiting block 8 is slidably connected to the inner cavity of the limiting cavity 7 via the threaded rod 9. The other end of the threaded rod 9, located at a corresponding position at one end of the crossbeam 2, is provided with a control screw. The drive module that rotates the threaded rod 9 has a limiting hole 10 that is opened through one end of the bearing housing 6. The interior of the limiting hole 10 is adapted to the limiting block 8, and the limiting block 8 is inserted into the inner cavity of the limiting hole 10. The insertion and engagement of the limiting block 8 and the limiting hole 10, combined with the axial preload of the threaded rod 9, can effectively resist vibration or impact loads and prevent the bearing housing 6 from loosening. The limiting block 8 provides axial positioning constraint and also shares part of the shear force through sliding engagement with the limiting cavity 7, thereby improving the resistance to lateral impact.

[0028] Preferably, the drive module includes: a drive rod 11, a first pulley 12, a belt 13, and a second pulley 14. The drive rod 11 is rotatably connected to one side of the support frame 1. The first pulley 12 is fixedly mounted on the surface of the drive rod 11. The belt 13 is adapted to be connected to the surface of the first pulley 12. Two sets of second pulleys 14 are fixedly mounted on one end of two sets of threaded rods 9 and located at the corresponding ends of two sets of crossbeams 2. The surface of the second pulley 14 is adapted to be matched with the belt 13. The two sets of second pulleys 14 are connected to the first pulley 12 through the belt 13. A single drive rod 11 controls the rotation of the threaded rods 9 on both sides simultaneously through the pulley system, ensuring that the limit blocks 8 on both sides move synchronously, avoiding tilting of the guide wheel or damage to the bearing due to unilateral operation.

[0029] Preferably, the top of the support frame 1 and both ends of the two sets of crossbeams 2 are provided with fixing components for fixing the crossbeams 2; the fixing components include: fixing grooves 15, fixing holes 16, through holes 17, and fixing rods 18. The fixing grooves 15 are adapted to be opened on the top of the support frame 1, and the interior of the fixing grooves 15 is adapted to be arranged at one end of the crossbeams 2. One end of the crossbeams 2 is connected to the inner cavity of the fixing grooves 15. The inner wall of the fixing grooves 15 is opened through the fixing holes 16, the through holes 17 are opened through the top end of the crossbeams 2, and the fixing rods 18 are located above one end of the crossbeams 2. The bottom end of the fixing rod 18 is fitted to the inside of the through hole 17 and the inside of the fixing hole 16. The bottom end of the fixing rod 18 passes through the inner cavity of the through hole 17 and is threaded to the inner cavity of the fixing hole 16. The two ends of the crossbeam 2 are embedded in the fixing groove 15 on the top of the support frame 1. Through the strict fit between the groove and the end of the crossbeam 2, quick alignment is achieved, ensuring the horizontality and verticality of the crossbeam 2 during installation and avoiding repeated manual adjustments. The through hole 17 on the crossbeam 2 and the fixing hole 16 on the inner wall of the fixing groove 15 are pre-aligned, which simplifies the insertion path of the fixing rod 18 and reduces the installation complexity.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
