DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0028] Example 1, reference Figures 1 to 3 , which is the first embodiment of the present invention, provides a brake disassembly device, including a brake body 100, including a shell 101, a bushing 102 arranged on the inner side of the shell 101, and a piston 103 arranged on the inner side of the bushing 102; a support mechanism 200, including a first support member 201 and a second support member 202, the first support member 201 is connected to the shell 101, and the second support member 202 is connected to the bushing 102; a disassembly mechanism 300, including a hydraulic jack 301 and a lifting rod 302, the hydraulic jack 301 is arranged between the first support member 201 and the second support member 202, and the piston 103 is separated from the bushing 102 by the lifting rod 302.

[0029] It should be noted that the support mechanism 200 is used to provide a stable support foundation for the disassembly process. It includes a first support member 201 and a second support member 202. The two components are respectively connected to the housing 101 and the bushing 102 of the brake. The first support member 201 is connected to the housing 101 through a connecting nut 101a, and the second support member 202 is connected to the connecting hole at the end of the bushing 102 through a bolt. This design ensures that during the disassembly process, the housing 101 and the bushing 102 can be firmly fixed in place to prevent displacement or damage due to external force. The coordinated use of the first support member 201 and the second support member 202 provides a solid support point for subsequent disassembly work and ensures the stability and reliability of the operation.

[0030] It should also be noted that the function of the disassembly mechanism 300 is to separate the piston 103 from the bushing 102. The hydraulic jack 301 is arranged between the first support member 201 and the second support member 202. The bushing 102 can be pushed downward by the jacking force generated by the hydraulic jack 301, so that the bushing 102 is separated from the piston 103. This separation method avoids the violent pulling and collision that may occur in traditional manual disassembly, and reduces the damage to the brake components. The lifting rod 302 is used to further lift the piston 103 out of the brake after the bushing 102 is separated from the piston 103. The end of the lifting rod 302 is a pull ring 302a, which is connected to the threaded hole at the end of the piston 103 through a threaded rod. By rotating the threaded rod, the piston 103 can be smoothly lifted out.

[0031] Specifically, the housing 101 is circular, and four groups of connecting nuts 101 a are evenly distributed on the outer wall of the housing 101 with the center of the circle as the central axis.

[0032] Furthermore, the inner side of the bushing 102 is in close contact with the inner wall of the housing 101 , and the inner side of the bushing 102 is in close contact with the outer wall of the piston 103 . A plurality of connection holes are evenly distributed on the end of the bushing 102 ; a plurality of threaded holes are evenly distributed on the end of the piston 103 .

[0033] Example 2, reference Figures 1 to 3 This embodiment is different from the first embodiment in that: the first support member 201 includes a first support rod 201a and a first connecting rod 201b, the first support rod 201a is provided with two groups, the first connecting rod 201b is connected to the ends of the two groups of first support rods 201a at the same time, and a first through hole is opened at the end of the first support rod 201a away from the first connecting rod 201b.

[0034] Specifically, the second support member 202 includes a second support rod 202a and a second connecting rod 202b. The second support rod 202a is provided with two groups. A bolt is connected to the bottom end of the second support rod 202a. The bolt and the second support rod 202a have the same central axis. The bolt can rotate the second connecting rod 202b along the central axis and connect with the ends of the two groups of second support rods 202a at the same time. A second through hole is opened at the end of the second support rod 202a away from the second connecting rod 202b; the length of the first support rod 201a is greater than the length of the second support rod 202a.

[0035] The first through hole is matched with the connecting nut 101 a, and the first supporting member 201 is connected to the housing 101 via the connecting nut 101 a.

[0036] Furthermore, the first through hole is adapted to the connecting nut 101 a , and the first support member 201 is connected to the housing 101 via the connecting nut 101 a .

[0037] The rest of the structure is the same as that of Example 1.

[0038] Example 3, reference Figures 1 to 3 , this embodiment is different from the above embodiments in that: the end of the hydraulic jack 301 conflicts with the first connecting rod 201b, and the bottom end of the hydraulic jack 301 conflicts with the second connecting rod 202b.

[0039] It should be noted that the function of the hydraulic jack 301 is to provide a controllable force to achieve the separation of the bushing 102 and the piston 103. Specifically, the end of the hydraulic jack 301 conflicts with the first connecting rod 201b, and the bottom end conflicts with the second connecting rod 202b. This design enables the hydraulic jack 301 to apply force between the two supporting points, thereby pressing the bushing 102 downward to separate it from the piston 103. The application of this force is uniform and controllable, avoiding damage to components due to excessive force, and also reducing the physical demand on the operator.

[0040] Specifically, the end of the lifting rod 302 is a pull ring 302a, the bottom end of the pull ring 302a is fixedly connected to a vertical rod 302b, one end of the vertical rod 302b away from the pull ring 302a is fixedly connected to a limiting nut 302c, and a threaded rod is fixedly connected below the limiting nut 302c.

[0041] It should be noted that the lifting rod 302 is used to lift the piston 103 out of the brake after the bushing 102 is separated from the piston 103. The end of the lifting rod 302 is a pull ring 302a, which allows the operator to easily hold and apply force. The bottom end of the pull ring 302a is fixedly connected to a vertical rod 302b, and the end of the vertical rod 302b away from the pull ring 302a is fixedly connected to a limiting nut 302c, and a threaded rod is fixedly connected below the limiting nut 302c. This arrangement allows the lifting rod 302 to be stably connected to the threaded hole at the end of the piston 103, and the piston 103 can be lifted up by rotating the threaded rod. The limiting nut 302c here plays the role of fixing and limiting the movement of the threaded rod, thereby ensuring the stability and safety of the lifting rod 302 during the extraction process.

[0042] Furthermore, two sets of lifting rods 302 are provided, and the bottom ends of the lifting rods 302 are connected to the threaded holes at the ends of the pistons 103. This arrangement allows forces to be applied to the pistons 103 from two directions at the same time during the disassembly process, which can distribute the forces more evenly and reduce the risk of damage to the pistons 103 or the threaded holes. At the same time, the design of two sets of lifting rods 302 also provides operational flexibility, and the most appropriate lifting direction and force can be selected according to actual conditions.

[0043] The rest of the structure is the same as that of Example 2.

[0044] Operation process: first unscrew the connecting nut 101a on the outside of the shell 101, then pass the connecting nut 101a through the first through hole at the bottom end of the first support rod 201a, and then install the connecting nut 101a back to the original position of the shell 101. After connecting the first support rods 201a on both sides to the shell 101, connect the second support rod 202a to the connecting hole at the end of the bushing 102 through the bolts at its bottom end, and then check whether the first support rod 201a and the shell 101, the second support rod 202a and the bushing 102 are connected and tightened. When it is determined that the first support rod 201a and the shell 101, the second support rod 202a and the bushing 102 are connected and tightened, place the hydraulic jack 301 between the first connecting rod 201b and the second connecting rod 202b, and ensure that the end of the hydraulic jack 301 conflicts with the first connecting rod 201b, and the bottom end of the hydraulic jack 301 conflicts with the second connecting rod 202b.

[0045] Then, the hydraulic jack 301 is started, and the bushing 102 is pushed downward by the hydraulic jack 301 until the bushing 102 is separated from the piston 103;

[0046] When the bushing 102 is separated from the piston 103, align the threaded rod at the bottom end of the lifting rod 302 with the threaded hole at the end of the piston 103, and then use a tool to rotate the threaded rod until the threaded rod is completely screwed into the threaded hole. At this time, use a steel rod to pass through the two sets of lifting rods 302 at the same time, and then pull the steel rod upward to lift the piston 103 out of the brake.
