Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, the embodiment of the present application discloses a coupling disassembly and assembly tool, comprising:

[0025] L-shaped frame 1, moving device 2 and lifting device 3;

[0026] The moving device 2 is arranged at the bottom of the L-shaped frame 1;

[0027] The hoisting device 3 is arranged on the L-shaped frame 1;

[0028] The lifting device 3 includes a winch 301 and a guide mechanism 302. The guide mechanism 302 is arranged on the upper part of the L-shaped frame 1, and the winch 301 is arranged at the lower part of the guide mechanism 302. The winch 301 is connected to a rope, and the other end of the rope passes through the guide mechanism 302 and is connected to a hook 303. The hook 303 is provided with a clamp 304 that matches the coupling shaft. Operating the winch 301 causes the hook 303 and the clamp 304 to move up and down relative to the winch 301.

[0029] The tooling of the present invention fixes the coupling by a clamp 304, and then uses a winch 301 installed on the L-shaped frame 1 to hoist the coupling to a required stress state to prevent it from accidentally falling after the coupling is removed. Thereafter, the moving device 2 on the tooling is used to move it away, and then the winch 301 is used to safely place the coupling on the ground, which can effectively avoid unsafe situations caused by transportation during personnel maintenance.

[0030] In the embodiment of the present application, there is no specific limitation on the specifications of the winch 301 . A manual winch may be used, or a drive motor may be installed on the L-shaped frame 1 to automatically control the rotation of the winch 301 .

[0031] like Figure 2 As shown, specifically, the clamp 304 in the embodiment of the present application includes two semicircular clamps 304 that cooperate with each other, the upper part of the clamp 304 is provided with a lifting ear 305, and the lower part is provided with a bolt hole, the hook 303 is set through the lifting ear 305, and the bolt 306 is passed through the bolt hole to detachably fix the two semicircular clamps 304, which is not only convenient when fixing the coupling, but also does not damage the shaft and the coupling.

[0032] Specifically, the L-shaped frame 1 in the embodiment of the present application includes a vertical frame 101 and a horizontal frame 102 fixed perpendicular to each other, a first support rod 103 and a second support rod 104 perpendicular to the vertical frame 101 are fixed inside the vertical frame 101, and the winch 301 is arranged on the side of the first support rod 103 away from the horizontal frame 102.

[0033] The L-shaped frame 1 consists of a vertical frame 101 and a horizontal frame 102. Support rods are arranged inside the vertical frame 101. These designs ensure the stability and strength of the entire frame. The arrangement of the first support rod 103 and the second support rod 104 also provides additional support and positioning functions.

[0034] Specifically, the moving device 2 in the embodiment of the present application is a plurality of rollers symmetrically arranged at the lower part of the horizontal frame 102, which provides the possibility of flexible movement for the tooling and broadens the scope of use.

[0035] Specifically, the embodiment of the present application also includes a fixed beam 105 and a cross beam 106 arranged at the top of the vertical frame 101. The fixed beam 105 is fixedly connected to the cross beam 106 and the vertical frame 101, and is perpendicular to each other; two fixed beams 105 and two cross beams 106 are provided and connected as a whole, forming a rectangular shape, and the bottoms of the two fixed beams 105 are fixedly connected to the top of the vertical frame 101.

[0036] The fixing frame 105 and the crossbeam 106 are not only provided to strengthen the frame structure, but also can serve as a mounting base or additional support point for other components.

[0037] Specifically, the guide mechanism 302 in the embodiment of the present application includes a sliding shaft 312 and a guide hole 322. The sliding shaft 312 is arranged on the inner side of the beam 106 close to the side of the winch 301. A sliding track and a pulley are provided inside the other beam 106. The pulley and the sliding track are slidably connected, and the guide hole 322 is arranged on the pulley.

[0038] When the pulley slides inside the sliding track, it can drive the guide hole 322 to move together, and can automatically adjust according to the different force directions. Together with the sliding shaft 312, it saves effort in lifting work, making the movement of the rope more stable and free during operation, reducing unnecessary friction and resistance.

[0039] Specifically, the rope in the embodiment of the present application passes through the sliding shaft 312 and the guide hole 322 in sequence.

[0040] Specifically, reinforcing steel is fixed to the outside of the fixed beam 105 in the embodiment of the present application, which provides additional support for the fixed frame 105, can significantly improve the ability of the fixed beam 105 to resist deformation, and reduce the risk of deformation and damage of the structure.

[0041] The specific workflow of the embodiment of this application is as follows:

[0042] First, place the tooling directly under the coupling, loosen the bolts that secure the coupling, and then use the special clamp 304 on the tooling to securely fix the coupling. Next, use the winch 301 installed on the tooling to lift the coupling to the required stress state to prevent the risk of accidental falling after removing the bolts that secure the coupling. The guide hole 322 can also be adjusted according to the stress state. After loosening the bolts, separate the coupling from the pump body through the moving device 2 on the tooling, and use the winch 301 to safely place the coupling on the ground.

[0043] It can be seen that the coupling disassembly and assembly tool of the present invention fixes the coupling by the clamp 304, and then uses the winch 301 installed on the L-shaped frame 1 to hoist the coupling to the required stress state to prevent it from accidentally falling after the coupling is removed. Thereafter, the moving device 2 on the tool is used to move it away, and then the coupling is safely placed on the ground by the winch 301, which can effectively avoid unsafe situations caused by transportation during personnel maintenance.
