[0026] The terms used in the present application are those general terms currently widely used in the art in consideration of the functions about the present application, but these terms can be changed according to the intention of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms can be selected by the applicant, and in this case, the detailed meaning thereof will be described in the detailed description of the present application. Therefore, the terms used in the specification should not be understood as simple names, but based on the meaning of the terms and the overall description of the present application.

[0027] With reference to Figures 1-5 , the embodiment provides a connecting mechanism, which comprises a connecting plate 1 and a variable face plate 2 connected with the connecting plate 1, the variable face plate 2 is used for being in contact with a part, and the connecting plate 1 is used for transmitting external force to the variable face plate 2 and driving the variable face plate 2 to move; the connecting plate 1 is in a split type, the connecting plate 1 comprises a first plate 11 and a second plate 12, and the connecting plate 1 and the variable face plate 2 are connected through bolts, and it is to be explained that the first plate 11 is provided with an arc-shaped groove 15 at a center position of a straight end, the second plate 12 is also provided with an arc-shaped groove 15 at a center position of a straight end, and the two groups of arc-shaped grooves 15 are spliced into a complete circular groove.

[0028] Specifically, with reference to Figure 2 , the connecting plate 1 is provided with a containing groove 13 on one side, and the containing groove 13 is provided with a connecting through hole 14;

[0029] The first plate 11 and the second plate 12 are the same in structure, and the first plate 11 and the second plate 12 are symmetrically arranged, and it is to be explained that the connecting plate 1 serves as a medium for transmitting external force, transmits the force applied from outside to the variable face plate 2, thereby driving the variable face plate 2 to move, and further realizing the dismounting operation on the part, the connecting plate 1 is designed in a split type (composed of the first plate 11 and the second plate 12) to facilitate assembly and disassembly with the variable face plate 2, and it is more convenient to operate and adjust in different use scenarios.

[0030] Wherein, with reference to Figure 4 , the variable face plate 2 is in a split type, the variable face plate 2 comprises a first face plate 21 and a second face plate 22, the first face plate 21 is semicircular, the first face plate 21 is provided with a plurality of first connecting holes 23, and a semicircular through groove 24 is formed at a center position of a straight end of the first face plate 21; the variable face plate 2 is provided with a polygonal recess at an end portion, the polygonal recess is in communication with the first connecting hole 23, and it is to be explained that the diameter of the semicircular through groove 24 is smaller than the diameter of the arc-shaped groove 15.

[0031] Further, with reference to Figure 4 , the first face plate 21 and the second face plate 22 are the same in structure, and the first face plate 21 and the second face plate 22 are mirror image arranged with a straight end edge line as an axis of symmetry; in a use state, the joint portions of the first plate 11 and the second plate 12 are staggered with the joint portions of the first face plate 21 and the second face plate 22, and the connecting through hole 14 is in communication with the first connecting hole 23.

[0032] It should be noted that the variable law disc 2 is directly in contact with the parts, and according to the shape and connection mode of the parts, the variable law disc 2 can provide a suitable contact and connection interface. For parts (such as bearing X) that cannot be directly connected with the variable law disc 2 through bolts, the semicircular first law disc 21 and the second law disc 22 can be spliced around the parts, and the semicircular through groove 24 and the shape characteristics thereof are used to realize effective action on the parts.

[0033] The first connecting hole 23 is used to connect with the connecting plate 1, so that the variable law disc 2 and the connecting plate 1 become an integral whole and can move synchronously under stress. The polygonal groove is in communication with the first connecting hole 23, which may be used to further position or prevent the bolts from rotating when the bolts are connected, thereby enhancing the stability of the connection.

[0034] The symmetry and mirror image of the first law disc 21 and the second law disc 22, and the staggered manner of the joint with the connecting plate 1, ensure the stability of the structure and the reliability of the connection, so that the entire connecting mechanism can uniformly transmit force under stress, avoiding the occurrence of weak links or uneven stress, thereby better completing the disassembly work of the parts.

[0035] Referring to Figure 1 , Figure 3 and Figure 5 , when it is necessary to disassemble parts such as shaft couplings and bearings X that cannot be connected with the variable law disc 2 through bolts during use, the variable law disc 2 in this embodiment can be used to contact the corresponding parts. Taking the bearing X as an example, as shown in Figure 5 , the end of the bearing X close to the equipment is the back surface, and the end of the bearing X close to the output shaft is the front surface. The specific way to disassemble the bearing X is as follows: first, place the first law disc 21 and the second law disc 22 on the back surface of the bearing X in sequence, and splice the outer walls of the first law disc 21 and the second law disc 22 into a complete circle. At this time, the semicircular through grooves 24 on the first law disc 21 and the second law disc 22 are also spliced into a complete circle. It should be noted that the diameter of the circle formed by splicing the two groups of semicircular through grooves 24 is smaller than the diameter of the back surface of the bearing X. Then, the first plate 11 and the second plate 12 of the connecting plate 1 are connected with the first law disc 21 and the second law disc 22 through bolts, respectively. At this time, the connecting bolts pass through the first connecting hole 23 of the variable law disc 2 and the connecting through hole 14 of the connecting plate 1 at the same time. It should be particularly noted that the joint between the first plate 11 and the second plate 12 is staggered with the joint between the first law disc 21 and the second law disc 22. At this time, the variable law disc 2 is connected with the connecting plate 1.

[0036] It should be noted that the variable law disc 2 in this embodiment is provided in multiple specifications, and the difference between each specification is that the diameter of the semicircular through groove 24 is different, so that it can adapt to bearings X of different specifications.

[0037] As an optional embodiment, referring toFigure 6 The variable method disc 2 is circular, a circular through groove 25 is arranged at the center of the variable method disc 2, a plurality of second connecting holes 26 are arranged annularly on the variable method disc 2, a plurality of third connecting holes 27 are arranged annularly between the second connecting holes 26 and the circular through groove 25; in the use state, the connecting through hole 14 is in communication with the second connecting hole 26, and a polygonal recess is arranged at the end of the variable method disc 2 and is in communication with the second connecting hole 26; it should be noted that the purpose of the polygonal recess is to place a bolt, so that the end of the bolt is located in the polygonal recess, thereby further limiting the bolt, so that the bolt cannot easily rotate.

[0038] Further, referring to Figure 6 The variable method disc 2 is connected with the connecting plate 1 through the second connecting hole 26, and the variable method disc 2 is connected with the parts through the third connecting hole 27.

[0039] It should be noted that, referring to Figure 6 The function of the circular through groove 25 is to adapt to parts of different diameters, by changing the diameter of the circular through groove 25, so that the variable method disc 2 can be used with parts of various diameters, providing a suitable space and connection position for the parts during disassembly, and enhancing the versatility of the variable method disc 2.

[0040] The second connecting hole 26 is used for connecting with the connecting plate 1, and is in communication with the connecting through hole 14 of the connecting plate 1 in use, and the stable connection of the two is realized through the bolt, so that the connecting plate 1 can effectively transmit external force to the variable method disc 2, so that the variable method disc 2 can move synchronously with the connecting plate 1 under stress, and the smooth disassembly operation is ensured.

[0041] The third connecting hole 27 is used for connecting with the parts, when there is a corresponding threaded hole on the parts, the bolt can pass through the third connecting hole 27 and be screwed with the parts, so that the variable method disc 2 is tightly combined with the parts, so that the parts are moved together during disassembly, and the disassembly of the parts is realized.

[0042] The main purpose of the polygonal recess is to limit the connecting bolt, by placing the end of the bolt in the polygonal recess, the bolt can be effectively prevented from rotating easily during use, further enhancing the stability of the connection between the variable method disc 2 and the connecting plate 1 and the parts, ensuring that the connecting structure will not loosen during the stress process, and ensuring the safe and effective performance of the disassembly work.

[0043] In use, referring to Figure 7 When it is necessary to disassemble the parts such as the speed reducer Y on the shaft coupling and the fluid coupling which can be connected with the variable method disc 2 through the bolt, the third connecting hole 27 on the variable method disc 2 can be aligned with the threaded hole, and then the variable method disc 2 is connected with the parts through the bolt;

[0044] Take the reduction gear Y on the dismounting hydraulic coupler as an example, the third connecting hole 27 on the variable law disc 2 is aligned with the threaded hole at the end of the reduction gear Y, then the third connecting hole 27 on the variable law disc 2 is connected with the threaded hole at the end of the reduction gear Y through the bolt, then the connecting through hole 14 on the first plate 11 and the second plate 12 of the connecting plate 1 is aligned with the second connecting hole 26 on the variable law disc 2, the bolt is simultaneously penetrated through the connecting through hole 14 and the second connecting hole 26 and connected with the nut to connect the variable law disc 2 with the connecting plate 1, at this time the variable law disc 2 is simultaneously connected with the connecting plate 1 and the end of the reduction gear Y.

[0045] It should be noted that in the embodiment, the variable law disc 2 is a one-piece structure, a circular through slot 25 is formed at the center position of the variable law disc 2, and the variable law disc 2 is embodied in that the circular through slot 25 with different diameters can be arranged, so as to adapt to the parts with different diameters.

[0046] Referring to Figure 3 , Figure 5 and Figure 7 , the embodiment provides a dismounting device, which comprises a connecting mechanism, further comprises a supporting part 3 and a jack 4 arranged on the supporting part 3, the supporting part 3 is arranged on the connecting plate 1, and the jack 4 is used for providing a power source for dismounting the part; the base end of the jack 4 is in contact with the supporting part 3, and the other end of the jack 4 is in contact with the part; the supporting part 3 comprises a gear plate 31 arranged on the connecting plate 1 and an I-beam 33 arranged on the gear plate 31, the gear plate 31 is provided with two groups, the two groups of gear plates 31 are respectively in contact with the first plate 11 and the second plate 12, and a plurality of I-beam grooves 32 are arranged on the gear plate 31 and matched with the I-beam 33.

[0047] Referring to Figure 2 , the connecting plate 1 is provided with a connecting groove, the end of the gear plate 31 is matched with the connecting groove, and the connecting mode of the connecting plate 1 and the gear plate 31 can also be selected as hinged or welded at the end of the connecting plate 1 and the gear plate 31, it should be noted that the connecting mode of the gear plate 31 and the connecting plate 1 can adopt the plug-in type, or the end of the gear plate 31 can be welded on the end of the connecting plate 1, or the end of the gear plate 31 can be hinged with the end of the connecting plate 1, as long as the effect of connecting and supporting the connecting plate 1 and the jack 4 in the embodiment can be achieved.

[0048] Further, referring to Figure 3 , the end of the jack 4 is provided with a code block 41. It should be noted that the code block 41 is used to compensate the distance between the jack 4 and the part when the distance between the jack 4 and the end of the part is far, and the I-beam groove 32 on the gear plate 31 cannot meet the distance between the jack 4 and the part, so that the code block 41 is placed between the end of the jack 4 and the end of the part, thereby making up the distance difference between the two.

[0049] Operation process: Refer to Figures 1-5 As in Embodiment 1, taking the disassembly of bearing X as an example, after the variable disk 2 is installed on the back of bearing X and the connecting plate 1, one end of the stop plate 31 is inserted into the connecting groove at the end of the connecting plate 1. Then, according to the distance between the jack 4 and the end of the output shaft penetrating bearing X, the I-beam 33 is inserted into the corresponding I-beam groove 32 of the stop plate 31. Then, the base of the jack 4 is placed on the end face of the I-beam 33, and the other end of the jack 4 is placed on the end of the output shaft penetrating bearing X. Then, the jack 4 is pressed down. When the length of the jack 4 increases, the jack... 4. Under the action of the stop plate 31 and the I-beam 33, the connecting plate 1 and the variable disk 2 are driven to move towards the end of the output shaft. Since the diameter of the semi-circular through groove 24 of the variable disk 2 is smaller than the diameter of the back of the bearing X (that is, the diameter of the contact surface between the bearing X and the variable disk 2), when the variable disk 2 moves towards the end face of the output shaft, it drives the bearing X to move towards the end of the output shaft at the same time. As a result, when the jack 4 becomes longer, the variable disk 2 drives the bearing X to move towards the output shaft until it is disengaged from the output shaft. At this point, the work of removing the bearing X from the output shaft is completed.

[0050] For example, in Example 2, refer to Figures 6-7 Taking the disassembly of the reducer Y at the end of the hydraulic coupling as an example, firstly, the variable plate 2 is passed through the outer wall of the reducer Y end, so that the third connecting hole 27 on the variable plate 2 overlaps with the threaded hole on the reducer Y. Next, the bolt is passed through the third connecting hole 27 on the variable plate 2 and connected to the threaded hole on the reducer Y. At this time, the variable plate 2 is connected to the outer wall of the reducer Y end. Then, one end of the stop plate 31 is inserted into the connecting groove at the end of the connecting plate 1. Then, according to the distance between the jack 4 and the end of the reducer Y, the I-beam 33 is inserted into the corresponding I-beam groove 32 of the stop plate 31. Then, the base of the jack 4 is placed on the end face of the I-beam 33, and the other end of the jack 4 is placed on the end of the reducer Y. Then, the jack 4 is pressed. When the length of the jack 4 increases, the jack 4, under the action of the stop plate 31 and the I-beam 33, drives the connecting plate 1 and the variable plate 2 to move towards the I-beam 33 until the reducer Y is completely disengaged from the hydraulic coupling.

[0051] If the traditional method of using a lead screw for disassembly is adopted, the hydraulic coupling is tightly connected to the reducer Y. During the disassembly process, the lead screw may break or become impossible to turn, making it impossible to disassemble the parts. When using the method of the present invention, the jack 4 is used, and its force is much greater than that of human power. Moreover, the worker only needs to use less force to disassemble the parts.

[0052] It should be noted that this invention allows for the disassembly of various types of components using either an integrated or separate variable disk 2. For enterprises, only the corresponding specification of variable disk 2 needs to be prepared, and the operation is convenient and labor-saving. The wide applicability of this invention is also reflected in the fact that force can be applied to the components in two directions, "push" or "pull," during the disassembly process. This allows it to adapt to different types and specifications of components, as well as components in different working scenarios. For example, when disassembling certain couplings, the coupling needs to be pushed towards the ground to separate it from the main body; when disassembling the hydraulic coupling reducer Y, the reducer Y needs to be pulled away from the hydraulic coupling to separate it from the hydraulic coupling. Therefore, this invention is extremely convenient in practical work.

[0053] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
