The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0029] The disassembly device 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, the disassembly device 100 of the embodiment of the utility model includes a bracket 1 and a clamping assembly 2.

[0031] The bracket 1 includes a frame body 11 and a connecting rod body 12, the connecting rod body 12 is movably arranged on the frame body 11 along a first direction, and the connecting rod body 12 includes a first end 121 and a second end 122 opposite to each other in the first direction. The clamping assembly 2 includes a mounting plate 21, a first clamping member 22 and a second clamping member 23, the mounting plate 21 is connected to the first end 121, and the first clamping member 22 is movably arranged on the mounting plate 21 along a second direction. The second clamping member 23 is movably arranged on the mounting plate 21 along a second direction, and the first clamping member 22 and the second clamping member 23 are opposite to each other in the second direction, and the second direction is perpendicular to the first direction.

[0032] The disassembly device 100 of the embodiment of the utility model clamps the target disassembly object by bringing the first clamping member 22 and the second clamping member 23 closer to each other in the second direction. After the first clamping member 22 and the second clamping member 23 clamp the target disassembly object, the connecting rod body 12 is moved in the first direction to remove the target disassembly object. Therefore, the disassembly device 100 of the embodiment of the utility model is easy to operate and improves the efficiency of disassembly.

[0033] Therefore, the disassembly device 100 of the embodiment of the utility model is easy to operate and improves the efficiency of disassembly.

[0034] The target disassembly object may be a valve core and a valve plug, or may be other components of a hydraulic support.

[0035] In order to make the present application easier to understand, the disassembly device 100 of the embodiment of the present utility model is further described below by taking the first direction being consistent with the up-down direction and the second direction being consistent with the left-right direction as an example.

[0036] In some embodiments, Figure 1-Figure 3 As shown, the mounting plate 21 is provided with a first guide hole 211 and a second guide hole 212 , which are opposite to each other in the left-right direction, and the extension direction of the first guide hole 211 and the extension direction of the second guide hole 212 are both consistent with the left-right direction.

[0037] The clamping assembly 2 further includes a first pressing member 24 and a second pressing member 25. The first pressing member 24 includes a first through hole 241 provided with a first internal thread, and the second pressing member 25 includes a second through hole 251 provided with a second internal thread. The first clamping member 22 includes a first guide portion 221, which is slidably disposed in the first guide hole 211, and the outer surface of the first guide portion 221 is provided with a first external thread that matches the first internal thread. The second guide portion 231 is slidably disposed in the second guide hole 212, and the outer surface of the second guide portion 231 is provided with a second external thread that matches the second internal thread.

[0038] After the first clamping member 22 and the second clamping member 23 approach each other in the second direction and clamp the target disassembly object, the first pressing member 24 cooperates with the first guide portion 221 so that the first pressing member 24 presses the first guide portion 221 onto the mounting plate 21, and the second pressing member 25 cooperates with the second guide portion 231 so that the second pressing member 25 presses the second guide portion 231 onto the mounting plate 21. Thus, the relative positions of the first clamping member 22 and the second clamping member 23 are fixed, so that the first clamping member 22 and the second clamping member 23 maintain a clamping state on the target disassembly object, thereby ensuring the clamping stability of the first clamping member 22 and the second clamping member 23.

[0039] In some embodiments, Figure 1-Figure 3As shown, the first clamping member 22 further includes a first clamping portion 222, the first clamping portion 222 is connected to the first guide portion 221, a first groove 2222 is provided on one side of the first clamping portion 222 adjacent to the second clamping member 23 in the left-right direction, the first groove 2222 is open at one end adjacent to the second clamping member 23 in the left-right direction, and a first tooth portion is provided on the wall surface of the first groove 2222. The second clamping member 23 further includes a second clamping portion 232, the second clamping portion 232 is connected to the second guide portion 231, a second groove 2322 is provided on one side of the second clamping portion 232 adjacent to the first clamping member 22 in the left-right direction, the second groove 2322 is open at one end adjacent to the first clamping member 22 in the left-right direction, and a second tooth portion is provided on the wall surface of the second groove 2322.

[0040] In other words, when the first clamping member 22 and the second clamping member 23 clamp the target disassembly object, the target disassembly object is located between the first groove 2222 and the second groove 2322. The first groove 2222 is provided with a first tooth portion, and the second groove 2322 is provided with a first tooth portion, thereby increasing the friction force of the first clamping member 22 and the second clamping member 23 on the target disassembly object, and further improving the clamping stability of the first clamping member 22 and the second clamping member 23.

[0041] In some embodiments, Figure 2-Figure 3 As shown, there are multiple first guide holes 211, and the multiple first guide holes 211 are spaced apart in the circumferential direction of the first clamping portion 222. There are multiple first guide portions 221, and the multiple first guide portions 221 are arranged in the multiple first guide holes 211 in a one-to-one correspondence. There are multiple second guide holes 212, and the multiple second guide holes 212 are spaced apart in the circumferential direction of the second clamping portion 232. There are multiple second guide portions 231, and the multiple second guide portions 231 are arranged in the multiple second guide holes 212 in a one-to-one correspondence. Thus, the first clamping portion 222 and the second clamping portion 232 can be subjected to more uniform force, ensuring that the first clamping portion 222 and the second clamping portion 232 can be more stable when the target object is disassembled.

[0042] In some embodiments, Figure 2-Figure 3 As shown, the disassembly device 100 of the embodiment of the utility model further includes a first plug-in connector 31 and a second plug-in connector 32. The first clamping portion 222 defines a third through hole 2221, and the first plug-in connector 31 is movably inserted in the third through hole 2221 along the up-down direction. The second clamping portion 232 defines a fourth through hole 2321, and the second plug-in connector 32 is movably inserted in the fourth through hole 2321 along the up-down direction. The third through hole 2221 and the fourth through hole 2321 are opposite to each other in the radial direction of the connecting rod body 12.

[0043] The whole set of valve cores of the bracket 1 has two disassembly holes which are opposite to each other in the radial direction. The whole set of valve cores can be disassembled by inserting the first plug-in component 31 and the second plug-in component 32 into the two disassembly holes of the whole set of valve cores respectively, and then rotating the connecting rod body 12 around the axial direction of the connecting rod body 12. Therefore, the disassembly device 100 of the embodiment of the utility model can disassemble various valve cores, so the disassembly device 100 of the embodiment of the utility model has high universality.

[0044] In some embodiments, Figure 2-Figure 3 As shown, the disassembly device 100 of the embodiment of the utility model further includes a first limiting rod 41 and a second limiting rod 42. The first limiting rod 41 is provided with a first insertion hole 311 on its outer circumference, and the first limiting rod 41 can be fitted in the first insertion hole 311. The second limiting rod 42 is provided with a second insertion hole 321 on its outer circumference, and the second limiting rod 42 can be fitted in the second insertion hole 321.

[0045] When the first connector 31 and the second connector 32 are used to disassemble the whole set of valve cores, the first connector 31 and the second connector 32 are respectively inserted into the third through hole 2221 and the fourth through hole 2321, and then the first limit rod 41 and the second limit rod 42 are respectively inserted into the first plug hole 311 and the second plug hole 321, so that the first connector 31 and the second connector 32 limit the movement of the first connector 31 and the second connector 32 in the up and down directions, so that the first connector 31 and the second connector 32 are more stable when disassembling the whole set of valve cores.

[0046] When the first connector 31 and the second connector 32 are not working, the first limit rod 41 and the second limit rod 42 are pulled out respectively, so as to facilitate the first connector 31 and the second connector 32 to be removed from the third through hole 2221 and the fourth through hole 2321, and prevent the first connector 31 and the second connector 32 from interfering with the movement of the first clamp 22 and the second clamp 23.

[0047] In some embodiments, Figure 2-Figure 3 As shown, the second through hole 251 corresponds to the first guide hole 211 in the vertical direction, and the third through hole 2221 corresponds to the second guide hole 212 in the vertical direction. This facilitates the first connector 31 and the second connector 32 to be taken out through the first guide hole 211 and the second guide hole 212, respectively, thereby further improving practicality.

[0048] In some embodiments, Figure 1As shown, the frame body 11 includes a fifth through hole 1111, the connecting rod body 12 is inserted into the fifth through hole 1111, the inner wall surface of the fifth through hole 1111 is provided with a third internal thread, and the outer peripheral surface of the connecting rod body 12 is provided with a third external thread matched with the third internal thread. Thus, the connecting rod body 12 can be moved in the up and down directions while rotating, making the disassembly device 100 of the embodiment of the utility model more convenient to operate.

[0049] In some embodiments, Figure 1 As shown, the frame 11 includes a support portion 111 and a rod portion 112, wherein the rod portion 112 is multiple, and the multiple rod portions 112 are connected to the support portion 111, and each rod portion 112 is located on a side of the support portion 111 adjacent to the first end 121 in the up-down direction, that is, the multiple rod portions 112 are located below the support portion 111. The size of each rod portion 112 in the up-down direction can be changed. Among them, the rod portion 112 can be a telescopic electric cylinder. In other words, each rod portion 112 can be telescopic, so that the frame 11 can adapt to the working surface of different working conditions, thereby further improving the practicality of the disassembly device 100 of the embodiment of the utility model.

[0050] In some embodiments, Figure 1 As shown, the embodiment of the utility model further includes a handle 5, and the handle 5 is connected to the second end 122. It is convenient for the operator to hold the handle 5 to control the movement of the connecting rod body 12, thereby further improving the practicality of the disassembly device 100 of the embodiment of the utility model.
