Description

Technical Field

[0001] The utility model relates to the technical field of wheel assembly disassembly, in particular to a disassembly tool. Background Art

[0002] The wheel assembly is a key component of a crane's operating mechanism, typically consisting of a wheel, axle, bearings, a bearing housing, and a coupling. Specifically, the coupling mounted on the wheel axle connects to the operating mechanism's drive shaft, enabling travel and operation. Therefore, if a wheel bearing fails during crane operation, the faulty wheel must be removed from the assembly line as quickly as possible, disassembled, and the damaged bearing replaced, allowing the wheel assembly to be repaired. Existing techniques typically use pulling claws tailored to the wheel assembly's specifications to separate the coupling from the wheel axle before bearing maintenance and replacement can be performed.

[0003] Combined with attachment Figure 1 As shown, during operation, the hydraulic puller 10' is usually mounted on the coupling counter-disc 101' in the coupling and rests on the coupling housing 102'. The central axis of the hydraulic puller 10' is pressed against the wheel axle 100', so that the coupling can be disengaged from the wheel axle 100' by pushing the wheel axle 100'. However, when the hydraulic puller 10' is mounted on the coupling, the coupling counter-disc 101' is subjected to uneven force, which may cause the hydraulic puller 10' to deform, affecting subsequent use. Therefore, how to use a disassembly tool for the coupling that is labor-saving, simple to operate, stable and practical, and suitable for various specifications of wheel sets for disassembly and maintenance is a problem that people in this field need to solve.

[0029] The wheel assembly is a key component of a crane's operating mechanism, typically consisting of a wheel, axle, bearings, a bearing housing, and a coupling. Specifically, the coupling mounted on the wheel axle connects to the operating mechanism's drive shaft, enabling travel and operation. Therefore, if a wheel bearing fails during crane operation, the faulty wheel must be removed from the assembly line as quickly as possible, disassembled, and the damaged bearing replaced, allowing the wheel assembly to be repaired. Existing techniques typically use pulling claws tailored to the wheel assembly's specifications to separate the coupling from the wheel axle before bearing maintenance and replacement can be performed.

[0030] Combined with attachment Figure 1 As shown, during operation, the hydraulic puller 10' is usually mounted on the coupling counter-disc 101' in the coupling and rests on the coupling housing 102'. The central axis of the hydraulic puller 10' is pressed against the wheel axle 100', so that the coupling can be disengaged from the wheel axle 100' by pushing the wheel axle 100'. However, when the hydraulic puller 10' is mounted on the coupling, the coupling counter-disc 101' is subjected to uneven force, which may cause the hydraulic puller 10' to deform, affecting subsequent use. Therefore, how to use a disassembly tool for the coupling that is labor-saving, simple to operate, stable and practical, and suitable for various specifications of wheel sets for disassembly and maintenance is a problem that people in this field need to solve.

[0031] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figure 2-Figure 4 As shown, this embodiment provides a disassembly tool for removing a coupling to be removed from a wheel axle 100 to be removed. The disassembly tool includes a disassembly base 10, a drive assembly 20 and an auxiliary plate 30. A U-shaped groove 111 is provided on the disassembly base 10. The drive assembly 20 is located in the disassembly base 10 and can pass through the coupling to be removed and then press against the wheel axle 100 to be removed. The coupling to be removed can be clamped in the U-shaped groove 111. The auxiliary plate 30 is movably provided on the disassembly base 10 to support the drive assembly 20.

[0033] Specifically, in this embodiment, the disassembly base 10 is connected to the coupling to be disassembled by a clamping connection, so that when the drive assembly 20 applies a pushing force to the wheel axle 100 to be disassembled connected to the coupling to be disassembled, the coupling to be disassembled can be pressed against the inner wall of the U-shaped groove 111 to separate from the wheel axle 100 to be disassembled, and in this process, the coupling to be disassembled and the inner wall of the U-shaped groove 111 are in full contact, so as to avoid the problem of uneven force caused by the use of the hydraulic puller 10' in the prior art in subsequent disassembly operations, thereby ensuring the stability of disassembly. Furthermore, the disassembly base 10 and the drive assembly 20 can be used repeatedly, and the setting of the U-shaped groove 111 in the disassembly base 10 can meet the disassembly operations of the coupling to be disassembled in wheel assemblies of different specifications, which can greatly reduce the operating costs and improve the operating efficiency. Specifically, the auxiliary plate 30 is arranged on the disassembly base 10 and is used to support the drive assembly 20, so as to ensure the stability of the disassembly process. For example, the disassembly base 10, the driving assembly 20 and the auxiliary plate 30 are all non-fixed, which can be easily classified, stored and reused, thereby improving the utilization rate of the device and the efficiency of the disassembly operation.

[0034] The specific structure of the disassembly tool in this embodiment is described below.

[0035] like Figure 2-Figure 4 As shown, the disassembly tool in this embodiment is used to remove the coupling to be removed from the wheel axle 100 to be removed. Optionally, the disassembly tool in this embodiment includes a disassembly base 10, a drive assembly 20, and an auxiliary plate 30. Specifically, the drive assembly 20 and the auxiliary plate 30 are both movably arranged in the disassembly base 10, and the drive assembly 20 can pass through the coupling to be removed and press against the wheel axle 100 to be removed. The coupling to be removed can be clamped on the disassembly base 10, so that when the drive assembly 20 applies a force to the wheel axle 100 to be removed, the coupling to be removed can be detached from the wheel axle 100 to be removed under the limit of the disassembly base 10. Furthermore, the auxiliary plate 30 is used to support the drive assembly 20 to ensure the stability of the disassembly process.

[0036] like Figure 2 and Figure 3As shown, in this embodiment, the disassembly base 10 includes a base body 11, and the base body 11 is provided with a rib 12 and a support bar 13, and the base body 11 is provided with a U-shaped groove 111, an accommodating space 112 and a through groove 113. Optionally, the U-shaped groove 111 is provided on one side of the base body 11, and the coupling to be disassembled can be clamped in the U-shaped groove 111, thereby enabling the coupling to be disassembled to be clamped in the base body 11 during the subsequent disassembly and assembly process, and to be separated from the wheel axle 100 to be disassembled under the action of the drive assembly 20. Specifically, the coupling to be disassembled includes a coupling counterplate 101 to be disassembled and a coupling housing 102 to be disassembled, and the coupling housing 102 to be disassembled is mounted on one end of the wheel axle 100 to be disassembled. In this embodiment, the drive assembly 20 can press against this end of the wheel axle 100 to be disassembled, thereby pushing the wheel axle 100 to be disassembled to move relative to the coupling to be disassembled to separate the two. Specifically, the specifications of the coupling to be disassembled are φ285mm-φ350mm.

[0037] Exemplarily, the coupling disc 101 to be disassembled can be clamped and limited to the inner side of the U-shaped groove 111, and the coupling housing 102 to be disassembled can be against the bottom of the U-shaped groove 111. Specifically, the inner diameter of the U-shaped groove 111 is larger than the outer diameter of the coupling housing 102 to be disassembled, and smaller than the outer diameter of the coupling disc 101 to be disassembled. Therefore, after the coupling to be disassembled is clamped in the U-shaped groove 111 from top to bottom, when the drive assembly 20 applies an outward force to it, the coupling disc 101 to be disassembled will be pressed against the inner side of the U-shaped groove 111 and limited thereto, and the wheel axle 100 to be disassembled will be detached from the coupling housing 102 to be disassembled under the action of the drive assembly 20, thereby completing the disassembly operation of the coupling to be disassembled. Exemplarily, the dimensions of the U-shaped groove 111 are d=200mm and h=270mm.

[0038] Optionally, a receiving space 112 is provided vertically through the disassembly base 10, and the U-shaped groove 111 is connected to the receiving space 112, and the drive assembly 20 is located in the receiving space 112, thereby ensuring the stable placement of the coupling to be disassembled and facilitating the disassembly of the drive assembly 20. Furthermore, a through-groove 113 is provided horizontally through the disassembly base 10, and the through-groove 113 is connected to the receiving space 112, and the auxiliary plate 30 can be passed through the through-groove 113, so that the drive assembly 20 can be placed on the auxiliary plate 30 to ensure stability. Furthermore, a support bar 13 is provided protruding from the outer side of the through-groove 113, and the top surface of the support bar 13 is located on the same plane as the bottom surface of the through-groove 113, thereby supporting the auxiliary plate 30 and ensuring the stable support of the auxiliary plate 30 in the through-groove 113, thereby improving the stability of the drive assembly 20. Exemplarily, the auxiliary plate 30 can be set as a plate-like structure made of wood or other materials. Accordingly, during actual operation, multiple auxiliary plates 30 can be used to support the driving assembly 20 as needed.

[0039] Furthermore, a plurality of ribs 12 are provided on the outside of the base body 11. By way of example, in this embodiment, four ribs 12 are provided, and are respectively located on the upper and lower sides of the through groove 113 to improve the mechanical strength of the base body 11. Specifically, the ribs 12 provided below are located below the support bar 13, thereby providing support for the support bar 13 and preventing the support bar 13 from breaking and affecting the disassembly operation. By way of example, in this embodiment, the base body 11 is an integrated structure, and is made of 30mm steel plates.

[0040] like Figure 4 As shown, in this embodiment, the drive assembly 20 includes a drive body 21 and a drive rod 22, and the drive body 21 is supported above the auxiliary plate 30. The drive rod 22 is rotatably connected to the drive body 21, and when the drive rod 22 is rotated, the drive body 21 can be driven to apply a force outward along its axial direction. Specifically, the drive body 21 is inserted into the coupling to be removed and then pressed against one end of the wheel axle 100 to be removed. After the coupling to be removed is clamped in the U-shaped groove 111, by rotating the drive rod 22, the drive body 21 can push the wheel axle 100 to be removed outward. Since the wheel axle 100 to be removed is tightly connected to the coupling to be removed, both will move outward until the coupling to be removed is pressed against the inside of the U-shaped groove 111 and is limited. The wheel axle 100 to be removed moves outward relative to the coupling to be removed until the two are separated and the disassembly work is completed. For example, in this embodiment, the drive assembly 20 is set as a 50t jack. In other embodiments, other pressure equipment can also be selected to perform the operation, which will not be repeated here.

[0041] Furthermore, the disassembly tool can also be provided with a gasket, which is placed on the auxiliary plate 30 and located below the drive assembly 20, so as to be clamped between the auxiliary plate 30 and the drive assembly 20 to avoid the auxiliary plate 30 causing wear on the drive assembly 20 during operation. At the same time, the gap between the drive assembly 20 and the auxiliary plate 30 can also be adjusted by the gasket so that the drive assembly 20 can be placed stably and better apply thrust to the wheel axle 100 to be disassembled.

[0042] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
