Specific embodiments

[0021] It should be noted that, without conflict, the embodiments in the present utility model and the features in the embodiments can be combined with each other. The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0022] Combined with reference to Figure 1 and Figure 2 As shown, the present utility model provides an installation and disassembly device for a hydraulic coupling 30. The installation and disassembly device for the hydraulic coupling 30 includes: a connecting sleeve 10; a hydraulic driving structure 20, including a hydraulic cylinder and a moving part. The hydraulic cylinder includes a cylinder barrel 21, and the moving part is installed in the cylinder barrel 21. The first end of the connecting sleeve 10 is connected to the first end of the cylinder barrel 21, and a first fixed connection structure is provided at the second end of the connecting sleeve 10; a thrust rod 40, the thrust rod 40 is connected to the moving part, and the moving part can drive the thrust rod 40 to perform a reciprocating linear motion along the axial direction of the cylinder barrel 21. The first end of the thrust rod 40 passes through the first end of the cylinder barrel 21 and the second end of the connecting sleeve 10 in sequence, and the second end of the thrust rod 40 passes through the second end of the cylinder barrel 21, and a second fixed connection structure is provided at the second end of the thrust rod 40; a buffer mounting structure 50, installed at the second end of the thrust rod 40, and can slide relative to the thrust rod 40 along the axial direction of the thrust rod 40, and along the axial direction of the thrust rod 40, the hardness of at least one side of the buffer mounting structure 50 is less than the hardness of the hydraulic coupling 30.

[0023] In this embodiment, the first end of the connecting sleeve 10 is sleeved on the first end of the cylinder barrel 21 and connected to the first end of the cylinder barrel 21. The second end of the connecting sleeve 10 is provided with a first fixed connection structure for fixedly connecting with the hydraulic coupler 30. Both ends of the ejector rod 40 pass through the two ends of the cylinder barrel 21 respectively. The second end of the ejector rod 40 is provided with a second fixed connection structure for fixedly connecting with the motor shaft 90. The moving part is a piston, which is connected to the ejector rod 40 and can move along with the movement of the piston. The cylinder barrel 21 and the piston of the present application can move relative to each other. That is, when the piston drives the ejector rod 40 to move along the axial direction of the cylinder barrel 21, the cylinder barrel 21 is stationary. When the piston cannot drive the ejector rod 40 to move along the axial direction of the cylinder barrel 21, the cylinder barrel 21 can move relative to the piston along the axial direction of the cylinder barrel 21. The realization of the above movement mode can adopt the hydraulic drive structure of the prior art, which will not be elaborated here.

[0024] When it is necessary to disassemble the hydraulic coupler 30 from the motor shaft 90, make the side where the connecting sleeve 10 is located face the hydraulic coupler 30 (as Figure 1 shown). The motor shaft 90 is provided with a first threaded hole 91. First, fixedly connect the first fixed connection structure with the hydraulic coupler 30, make the first end of the cylinder barrel 21 pass through the first end of the connecting sleeve 10, then connect the first end of the connecting sleeve 10 with the first end of the cylinder barrel 21. Then, make the moving part drive the ejector rod 40 to move towards the hydraulic coupler 30. After the first end of the ejector rod 40 penetrates into the first threaded hole 91 of the motor shaft 90 and abuts against the bottom of the first threaded hole 91, the moving part drives the ejector rod 40 to continue to move towards the hydraulic coupler 30. When the ejector rod 40 cannot continue to move towards the hydraulic coupler 30, at this time, the cylinder barrel 21 moves away from the hydraulic coupler 30 relative to the ejector rod 40 and drives the connecting sleeve 10 to move away from the hydraulic coupler 30 relative to the ejector rod 40. Since the second end of the connecting sleeve 10 is fixedly connected to the hydraulic coupler 30, the hydraulic coupler 30 can be pulled off the motor shaft 90, realizing the disassembly of the hydraulic coupler 30.

[0025] When it is necessary to install the hydraulic coupler 30 on the motor shaft 90, make the side where the buffer mounting structure 50 is located face the hydraulic coupler 30 (as Figure 2As shown in the figure, first, fixedly connect the second fixed connection structure to the first threaded hole 91 of the motor shaft 90. Then, insert the ejector rod 40 into the cylinder barrel 21 from the second end and let it pass through and out of the first end of the cylinder barrel 21. After the ejector rod 40 passes through the cylinder barrel 21, it is connected to the moving part. Then, drive the ejector rod 40 to move away from the hydraulic coupling 30 by the moving part. Since the ejector rod 40 is fixedly connected to the motor shaft 90, the ejector rod 40 cannot continue to move away from the hydraulic coupling 30. At this time, the cylinder barrel 21 moves towards the hydraulic coupling 30 relative to the ejector rod 40. During the movement, the cylinder barrel 21 abuts against the buffer mounting structure 50 and pushes the buffer mounting structure 50 to move towards the hydraulic coupling 30. The buffer mounting structure 50 abuts against the end face of the hydraulic coupling 30. As the cylinder barrel 21 continues to move, the buffer mounting structure 50 continues to push the hydraulic coupling 30 towards the motor shaft 90, finally realizing the installation of the hydraulic coupling 30. During the installation process, make the side of the buffer mounting structure 50 with a hardness less than that of the hydraulic coupling 30 face the hydraulic coupling 30, so as to avoid damaging the hydraulic coupling 30 during the installation process of the hydraulic coupling 30, and thus ensure the service life of the hydraulic coupling 30.

[0026] In one embodiment, the hydraulic coupling 30 includes a connecting portion 31, and a second threaded hole 32 is provided on the connecting portion 31. Both the first fixed connection structure and the second fixed connection structure are threaded structures. The first fixed connection structure is threadedly connected to the second threaded hole 32, and the second fixed connection structure is threadedly connected to the first threaded hole 91.

[0027] In one embodiment of the present invention, the buffer mounting structure 50 includes a first buffer block and a second buffer block. The second buffer block is located on the side of the first buffer block away from the cylinder barrel 21, and an elastic member is provided between the first buffer block and the second buffer block.

[0028] In this embodiment, both the first buffer block and the second buffer block can reduce the impact on the hydraulic coupling 30 during the installation process. By providing an elastic member between the first buffer block and the second buffer block, the direct collision between the first buffer block and the second buffer block can be reduced, which can not only play a buffering role but also have a shock-absorbing effect.

[0029] In one embodiment, the elastic member is a spring.

[0030] As Figure 1 shown, a handle 22 is provided on the cylinder barrel 21, which is convenient for the staff to lift the cylinder barrel 21.

[0031] In one embodiment of the present invention, the buffer mounting structure 50 includes a first buffer block and a second buffer block. The hardness of the first buffer block is greater than or equal to that of the cylinder barrel 21, and the hardness of the second buffer block is less than that of the hydraulic coupling 30.

[0032] In this embodiment, the hardness of the first buffer block is greater than or equal to the hardness of the cylinder barrel 21. In this way, the first buffer block can better absorb impacts and is not easily deformed when compressed, ensuring the structural stability of the buffer mounting structure 50. The hardness of the second buffer block is less than the hardness of the hydraulic coupling 30, which can prevent the second buffer block from scratching the hydraulic coupling 30 during the installation process, thereby ensuring the service life of the hydraulic coupling 30.

[0033] In one embodiment of the present invention, there are multiple elastic members, and the multiple elastic members are elastically abutted between the first buffer block and the second buffer block.

[0034] Through the above settings, the shock absorption effect and buffering effect of the buffer mounting structure 50 can be improved.

[0035] In one embodiment of the present invention, when projected along the axial direction of the cylinder barrel 21, the projection of the first buffer block covers the projection of the second end of the cylinder barrel 21.

[0036] Through the above settings, the contact area between the first buffer block and the cylinder barrel 21 can be ensured, and the structural stability during the installation process can be guaranteed.

[0037] In one embodiment of the present invention, the buffer mounting structure 50 is made of a metal material, and an anti-corrosion layer and a waterproof layer are sequentially coated on the outer surface of the buffer mounting structure 50 from the inside to the outside.

[0038] Through the above settings, on the one hand, the corrosion resistance of the buffer mounting structure 50 can be improved, and the service life of the buffer mounting structure 50 can be extended. On the other hand, it can prevent moisture from penetrating into the buffer mounting structure 50, reduce corrosion and damage caused by moisture, and thus reduce the frequency of maintenance and replacement and lower the maintenance cost.

[0039] In one embodiment of the present invention, the buffer mounting structure 50 is a rod-shaped structure.

[0040] In this embodiment, the buffer mounting structure 50 is a rod-shaped structure, which has a relatively simple structure and is easy to manufacture, and can reduce the manufacturing cost.

[0041] In one embodiment of the present invention, the installation and disassembly device for the hydraulic coupling 30 further includes a base 60 and a lifting support structure 70 installed on the base 60, and the lifting support structure 70 is used to support the cylinder barrel 21.

[0042] In this embodiment, the lifting support structure 70 is used to support the cylinder barrel 21. In this way, during the installation and disassembly processes, there is no need for workers to manually hold the cylinder barrel 21, which can reduce the labor intensity of the workers.

[0043] In an embodiment of the present utility model, the lifting and supporting structure 70 includes at least two lifting and supporting brackets arranged at intervals along the axial direction of the cylinder barrel 21. The lifting and supporting bracket includes a lifting part 71 and a U-shaped supporting part 72 which is drivingly connected to the lifting part 71. The supporting surface of the U-shaped supporting part 72 is configured to be adapted to the outer peripheral surface of the cylinder barrel 21.

[0044] Through the above arrangement, the contact area between the cylinder barrel 21 and the U-shaped supporting part 72 can be ensured, and further the supporting stability of the U-shaped supporting part 72 for the cylinder barrel 21 can be ensured.

[0045] In an embodiment, the U-shaped supporting part 72 is a U-shaped plate, and the lifting part 71 is a cylinder or an electric telescopic rod.

[0046] In an embodiment of the present utility model, a rubber pad is arranged on the supporting surface.

[0047] Through the above arrangement, it can be prevented that the cylinder barrel 21 is scratched when sliding relative to the U-shaped supporting part 72, thereby ensuring the service life of the cylinder barrel 21.

[0048] In an embodiment of the present utility model, the installation and disassembly device for the hydraulic coupling 30 further includes a base 60 and a lifting and supporting structure 70 installed on the base 60. The lifting and supporting structure 70 is used to support the cylinder barrel 21, and universal wheels 80 are arranged on the base 60.

[0049] Through the above arrangement, it is convenient for the staff to move the base 60, reducing the labor intensity of the staff.

[0050] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects: there are provided a connecting sleeve, a hydraulic driving structure, a ejector rod and a buffer mounting structure. The hardness of at least one side of the buffer mounting structure is less than the hardness of the hydraulic coupling.
