Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic cylinder disassembly and assembly machine technology, specifically a horizontal disassembly and assembly machine. Background Technology
[0002] In fields such as construction machinery and mining machinery, hydraulic cylinders (such as hydraulic cylinders) are core actuators, and their disassembly, assembly, and maintenance are crucial aspects of equipment repair. Horizontal disassembly and assembly machines, specifically designed for hydraulic cylinder disassembly and assembly, can use mechanical force to assist in the disassembly and installation of components such as cylinder end caps, significantly reducing manual labor intensity and improving operational efficiency.
[0003] The inventors discovered that existing horizontal disassembly and assembly machines often have fixed disassembly and assembly ends, which can only accommodate a limited number of wrenches or allow for coarse adjustments within a limited range of wrench sizes. When dealing with different models and specifications of hydraulic cylinders, the disassembly and assembly ends need to be changed, which is not only cumbersome and time-consuming, but may also lead to excessive clearance between the wrench and bolt due to insufficient adjustment precision. More importantly, in high-intensity disassembly operations, due to the lack of an effective tightening mechanism, the wrench is prone to relative slippage or loosening within the disassembly and assembly ends, which not only reduces disassembly efficiency but may also cause damage to the threads of the end cap and wrench damage. Furthermore, regarding the support of the hydraulic cylinder to be disassembled, existing support devices are mostly simple bracket structures with poor flexibility in height and angle adjustment, making it difficult to adapt to hydraulic cylinders of different lengths, diameters, and weights. When the hydraulic cylinder is placed on the support device, if the support point is not properly positioned or the support force is insufficient, the hydraulic cylinder is prone to shaking, tilting, or even shifting during disassembly and assembly. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model provides a horizontal disassembly and assembly machine.
[0005] The technical solution of this utility model is as follows:
[0006] A horizontal disassembly and assembly machine includes a base, a ratchet device is provided at one end of the base, and a disassembly and assembly component for installing and removing a disassembly wrench is installed on the side of the ratchet device near the center of the base.
[0007] The disassembly assembly includes a disassembly base that is mounted to the ratchet device, and the base is configured as a hollow opening relative to the front and rear sides of the ratchet device.
[0008] The disassembly and assembly base has first receiving grooves on both sides in the horizontal direction, and limit members extending away from the ratchet device are installed on both sides in the vertical direction of the disassembly and assembly base, and a second receiving groove is provided in the middle of the limit members.
[0009] The specific design of the disassembly and assembly base is that the disassembly and assembly base is set as a cylinder, and an annular plate is formed inward at one end near the ratchet device, and is fixed to the ratchet device by fasteners passing through the annular plate.
[0010] The specific design of the limiting component is as follows: the limiting component includes a base plate installed with the edge of the disassembly seat, and two limiting plates are installed on the front side of the base plate, and a second receiving groove is formed between the two limiting plates.
[0011] To improve the supporting capacity of the limiting plates, the maximum distance between the two limiting plates is less than the length of the base plate, and reinforcing ribs are provided between the outer side of the limiting plates and the base plate.
[0012] To improve the installation strength of the base plate, a support plate is connected to the side of the base plate away from the limiting plate at both ends, and the support plate is fixed to the disassembly seat.
[0013] In order to support the two ends of the disassembly wrench installed in the first and second receiving slots, and to ensure that it is parallel to the cylinder end cover to be disassembled during the disassembly process, thus ensuring the disassembly effect, the disassembly base is equipped with fixing plates on both sides in the horizontal direction, and elastic support members are installed on both the fixing plates and the base plate.
[0014] The elastic support is specifically designed as follows: the elastic support includes a sleeve installed on the base plate and the fixed plate, and the sleeve is located in the middle of the first receiving groove or the second receiving groove. A support spring is fitted on the outer end face of the sleeve, and a support block is installed on the end of the support spring away from the ratchet device.
[0015] In order to limit the path when disassembling the handle compression support spring and ensure movement in a direction perpendicular to the base plate or fixed plate, a guide rod is provided inside the support spring. One end of the guide rod is connected to the support block, and the other end passes through the base plate or fixed plate and is slidably connected to both.
[0016] To facilitate support of the hydraulic cylinder to be disassembled, a tail support is provided at the end of the base away from the ratchet device, and an intermediate support is provided on the base between the tail support and the ratchet device.
[0017] The beneficial effects of this utility model are as follows: This utility model is a horizontal disassembly and assembly machine. In terms of adaptability and adjustment precision, it addresses the problem of traditional disassembly and assembly machines having fixed disassembly and assembly end dimensions and only being able to accommodate a limited number of wrench sizes. This disassembly and assembly machine, through its disassembly and assembly base structure with first receiving grooves on both horizontal sides and second receiving grooves on both vertical sides, forms a multi-dimensional wrench accommodating space. Compared to traditional equipment, this design can accommodate more sizes of wrenches without changing the disassembly and assembly ends, adapting to the disassembly and assembly of many models of hydraulic cylinders. Through the bidirectional limiting component for the wrench, combined with the self-adaptive tightening of the elastic support component, the wrench is supported. This disassembly and assembly machine provides a continuous and stable tightening force through the support spring of the elastic support component. When the wrench is placed in the receiving groove, the support block always fits against the wrench under the action of the spring force. Combined with the lateral constraint of the first or second receiving groove, it can greatly reduce the wobbling or movement of the wrench. In high-intensity disassembly operations, it reduces the damage rate of the hydraulic cylinder end cap threads, ensures the integrity of the hydraulic cylinder disassembly, and is beneficial for subsequent maintenance and recycling.

[0030] Example
[0031] As mentioned in the background section, the inventors are dedicated to the research and design of disassembly and assembly machines. In actual use, for horizontal disassembly and assembly machines, due to the relatively fixed design dimensions of the disassembly and assembly ends, there are few models of disassembly wrenches 3 used for the same disassembly and assembly end. When disassembling some large or small hydraulic cylinders, the corresponding disassembly wrench 3 is not compatible with the disassembly and assembly end, which can easily lead to problems such as excessive gaps or difficulty in installation. Therefore, the inventors have made improvements to the existing disassembly and assembly ends and designed a new type of disassembly and assembly machine, which will be explained in detail below with reference to the illustrations.
[0032] This embodiment provides a horizontal disassembly and assembly machine, see [link / reference]. Figure 1 Its overall structure is based on the base 1, which can be made of cast iron and is rectangular in shape. Anchor bolt holes can be set at the four corners of the bottom to securely install the equipment on the ground.
[0033] In this embodiment, combined with Figure 2 and Figure 4 At one end of the base 1, a ratchet device 2 is bolted on. Existing technology is acceptable. It mainly includes a ratchet disc and telescopic cylinders connected at both ends, with the output ends of the two cylinders arranged in opposite directions. This allows the ratchet disc to rotate, providing the rotational power required for disassembly and assembly. On the side of the ratchet device 2 near the center of the base 1, a disassembly and assembly assembly for installing and removing a wrench 3 is fitted. Existing disassembly wrenches 3, such as... Figure 7As shown, the core component of this disassembly and assembly assembly is a disassembly and assembly base 4. The disassembly and assembly base 4 is hollow, and its two ends, which are parallel to the ratchet device 2, are designed to be open. This design makes it easy for operators to observe the internal working conditions and also facilitates the removal, placement, and installation of wrenches. Furthermore, during disassembly, the hydraulic cylinder, such as the jack of the fully mechanized mining support column, has a connecting part extending from the end cap to be disassembled, which allows the connecting part to enter the hollow disassembly and assembly base 4. In this solution, the disassembly and assembly base 4 is cylindrical in shape and forged from high-strength alloy steel, which not only ensures the stability of the structure but also allows it to withstand large torque forces.
[0034] Based on the above structure, an annular plate 7 is integrally formed inward at one end of the disassembly base 4 near the ratchet device 2. Multiple bolt holes are evenly distributed on the annular plate 7. By passing high-strength bolts or other fasteners through these bolt holes, the disassembly base 4 and the ratchet device 2 can be firmly connected together.
[0035] In this embodiment, a first receiving groove 5 is provided on each of the two sides of the horizontal direction of the disassembly base 4, and the two first receiving grooves 5 are symmetrically distributed. On each of the two sides of the vertical direction of the disassembly base 4, a limiting member 6 is installed, and these limiting members 6 extend away from the ratchet device 2. Each limiting member 6 includes a base plate 62 connected to the edge of the disassembly base 4. On the front side of the base plate 62, two limiting plates 63 are vertically welded, the two limiting plates 63 are parallel to each other, and the limiting plates 63 extend beyond the disassembly base 4. The space formed between them is the second receiving groove 61. The maximum distance between the two limiting plates 63 is less than the length of the base plate 62, so a certain space is left at both ends of the base plate 62. Furthermore, a triangular reinforcing rib 64 is welded between the outer side of the limiting plate 63 and the base plate 62. It can be fixed by full welding, which further enhances the overall structural strength of the limiting member 6, enabling it to withstand the lateral force generated during wrench operation.
[0036] To securely mount the base plate 62 onto the mounting base 4, a support plate 65 is welded to each end of the base plate 62 on the side opposite to the limiting plate 63. These support plates are fixed to the outer circumferential surfaces of the base plate 62 and the mounting base 4 respectively, providing positive support for the base plate 62.
[0037] It should be noted that, based on the above design, various smaller disassembly wrenches 3 can be installed in the first receiving grooves 5 opened at both ends of the disassembly base 4, thus adapting to the disassembly and assembly of small-sized hydraulic cylinders. Due to the design of the limiting member 6, the base plate 62 is installed vertically to the disassembly base 4 and extends outward. With the extension of the limiting plate 63, the distance between the two second receiving grooves 61 is greater than the distance between the two first receiving grooves 5, which allows for the installation of various larger disassembly wrenches 3, adapting to the disassembly and assembly of large-sized hydraulic cylinders. Compared with the fixed size design of the prior art, this solution greatly improves its applicability.
[0038] In addition, combined Figures 2-4 On both sides of the horizontal axis of the mounting base 4, a fixing plate 8 is welded. The fixing plate 8 is arranged parallel to the first receiving groove 5. Elastic support members 9 are installed on both the fixing plate 8 and the base plate 62. Each elastic support member 9 includes a sleeve 91 mounted on the base plate 62 or the fixing plate 8. The sleeve 91 is made of seamless steel pipe and is fixed in the corresponding position by welding. The sleeve 91 is located in the middle of the first receiving groove 5 or the second receiving groove 61. That is, the sleeve 91 on the fixing plate 8 is located on one side of the first receiving groove 5 and in the middle of the first receiving groove 5 in the vertical direction, while the sleeve 91 on the base plate 62 is located in the middle of the second receiving groove 61. A support spring 92 is fitted on the outer end face of the sleeve 91. The support spring 92 is a high-strength compression spring. One end of the spring abuts against the end face of the base plate 62, and the other end is connected to a support block 93. The support block 93 is made of wear-resistant cast iron, and its surface in contact with the wrench is polished to reduce wear on the wrench. Inside the support spring 92, there is also a guide rod 94. One end of the guide rod 94 is connected to the center of the support block 93, and the other end passes through the guide hole opened on the base plate 62 or the fixed plate 8. The guide rod 94 and the base plate 62 or the fixed plate 8 are in sliding fit. The guide rod 94 can freely extend and retract in the guide hole, thereby ensuring that the support block 93 moves in a straight line under the action of the spring force and avoiding deviation. During the disassembly process, the end cap of the hydraulic cylinder is unscrewed outward, and the disassembly wrench 3 moves along with it. Under the action of the support spring 92, the support block 93 is pushed to maintain the support effect on the disassembly wrench 3, which plays the role of smoothing the wrench.
[0039] In this embodiment, a tail end support 10 is installed on the base 1 at the end away from the ratchet device 2. Simultaneously, an intermediate support 11 is also installed on the base 1 between the tail end support 10 and the ratchet device 2. The intermediate support 11 includes a support unit and a clamping unit, which are combined... Figure 6 The support unit includes a support base 111, and an adjusting cylinder 112 is provided at the bottom of the support base 111. The adjusting cylinder 112 can drive the support base 111 to rise and fall, adapting to the support of hydraulic cylinders of different sizes. Its output end is connected to a mounting block 113, and the mounting block 113 has a V-groove in the middle. The tail end support 10 and the clamping unit both adopt an adjustable structure. Figure 5 The two have similar structural settings, therefore they are used Figure 5The following is a structural description of both components. The labels in the figures are for illustrative purposes only and are not intended to limit the scope of either component. Both components include a mounting plate 101 located on the base 1, with U-shaped plates 102 with downward-facing openings mounted at both ends of the mounting plate 101. A clamping block 103 is slidably disposed within the U-shaped plate 102 and slidably disposed with respect to the mounting plate 101. A clamping cylinder 104 is mounted on the outer side of the U-shaped plate 102, with its output end connected to the clamping block 103. The mounting plate 101 is slidably disposed with respect to the base 1 and can be fixed in place, thus adapting to the support requirements of hydraulic cylinders of different lengths, diameters, and weights.
