[0036] See also Figure 2-3 As shown, according to an embodiment of the present application, a cylinder disassembly and assembly tool is provided, comprising:

[0037] A base 1, wherein the base 1 is used to fix the bottom of the cylinder;

[0038] A pressing plate 2, wherein the pressing plate 2 is arranged on the top of the cylinder;

[0039] Adjusting members 3, at least two of the adjusting members 3 are arranged between the base 1 and the pressing plate 2, the adjusting members 3 can drive the pressing plate 2 to move along the axial direction of the cylinder, and the adjusting members 3 and the pressing plate 2 are detachably connected.

[0040] The cylinder disassembly and assembly tool provided in the embodiment of the present application includes a base 1, a pressure plate 2 and an adjustment member 3. The base 1 is used to firmly fix the bottom of the cylinder 8. The base 1 is usually made of a solid metal material and has sufficient strength and stability to withstand various forces and pressures during the disassembly and installation of the cylinder 8. The shape and size of the base 1 are fully considered according to the structure of the cylinder 8 to ensure that it can perfectly match the bottom of the cylinder 8 of different models and specifications to achieve a stable fixing effect.

[0041] The pressing plate 2 is arranged on the top of the cylinder 8 and cooperates with the base 1 to clamp the cylinder 8 from top to bottom. The pressing plate 2 is also made of high-strength metal material, and its surface is specially treated to prevent damage to the cylinder 8 when in contact with the cylinder 8. The size and shape of the pressing plate 2 are adapted to the top of the cylinder 8, ensuring uniform pressure on the cylinder 8 during disassembly and installation to prevent deformation or damage to the cylinder 8.

[0042] The adjusting member 3 can drive the pressing plate 2 to move along the axial direction of the cylinder 8, so as to gradually release and control the pressure of the internal spring 83 when the cylinder 8 is disassembled. The adjusting member 3 usually adopts a hydraulic rod, an electric telescopic rod or other components with adjustable length function. During use, the operator can control the telescopic distance of the adjusting member 3, accurately control the moving distance and speed of the pressing plate 2, realize the slow compression or release of the pressure of the internal spring 83 of the cylinder 8, realize the installation or disassembly of the cylinder 8, and improve the safety of disassembly; further, by adopting a detachable connection between the adjusting member 3 and the pressing plate 2, the installation and disassembly between the adjusting member 3 and the pressing plate 2 are convenient, which makes it easier to install and disassemble the cylinder 8, and also meets the installation and disassembly in different working scenes, thereby improving the versatility and flexibility of the tooling. Through the arrangement of the base 1, the pressing plate 2 and the adjusting member 3, not only the efficiency and quality of the disassembly and assembly of the cylinder 8 are improved, but also the labor intensity and safety risks of the operator are reduced, which has important practical application value.

[0043] It is understandable that the number of the adjusting members 3 is at least two. When the number of the adjusting members 3 is two, the adjusting members 3 are mostly installed between the pressing plate 2 and the base 1 to improve the uniformity of the force on the pressing plate 2 and improve the safety of the operation of the staff.

[0044] The pressing plate 2 comprises:

[0045] Plate body 21;

[0046] A fixing seat 22, the fixing seat 22 is arranged on the outer periphery of the plate body 21;

[0047] The plug-in rod 23 passes through the fixing seat 22 and is connected to the driving end of the adjusting member 3 .

[0048] In this technical solution, the plate body 21, as the main structure of the pressure plate 2, is usually made of high-strength metal material, has sufficient strength and rigidity, and can withstand the pressure of the spring 83 inside the cylinder 8. The shape and size of the plate body 21 can fit tightly with the top of the cylinder 8 to achieve effective compression of the cylinder 8. A fixing seat 22 is provided on the outer periphery of the plate body 21, and the fixing seat 22 serves to connect and fix the plug rod 23.

[0049] The fixing seat 22 is usually fixed to the plate body 21 by welding or bolting, which has high stability and reliability. The number and position of the fixing seat 22 ensure that the plug rod 23 can be accurately connected to the driving end of the adjustment member 3, and will not loosen or move during operation.

[0050] The plug-in rod 23 passes through the fixed seat 22 and is connected to the driving end of the adjusting member 3, so as to realize the connection between the pressing plate 2 and the adjusting member 3. The plug-in rod 23 is usually made of high-strength steel, which has good wear resistance and deformation resistance. The plug-in rod 23 is detachably connected to the fixed seat 22 and the driving end of the adjusting member 3 by means of a latch, a threaded connection, etc. This connection method facilitates the installation and removal of the pressing plate 2 and improves the operating efficiency of the tooling.

[0051] The base 1 comprises:

[0052] Supporting bottom plate 11;

[0053] The position limiting and fixing portion 12 is disposed on the supporting base plate 11 .

[0054] In this technical solution, the support base plate 11 serves as the foundation of the base 1 and is usually made of a heavy and solid metal material with excellent load-bearing capacity and stability. It can withstand the various forces generated by the cylinder 8 and the disassembly and assembly process, ensuring that the entire tooling will not shake or move during operation. The limit fixing portion 12 is arranged on the support base plate 11, which can fix the cylinder 8 from the bottom, providing a stable foundation for disassembly and installation of the cylinder 8.

[0055] The position limiting fixing part 12 comprises:

[0056] A limiting ring 121, wherein the limiting ring 121 is located above the supporting bottom plate 11, and a plurality of fixing ribs 122 are provided between the limiting ring 121 and the supporting bottom plate 11;

[0057] The limiting plate 123 is disposed on the fixed rib plate 122 , and the limiting plate 123 is located below the limiting ring 121 .

[0058] The limiting plate 123 is provided with a connecting member 4 .

[0059] In this technical solution, the limit ring 121 is located above the support base plate 11, providing a preliminary limit function for the cylinder 8. The limit ring 121 is usually made of high-strength metal material, with sufficient strength and rigidity to withstand the pressure that may be generated by the cylinder 8 during the disassembly and assembly process. The limit ring 121 is an annular structure. When the cylinder 8 is installed on the limit ring 121, the connection end 85 at the bottom passes through the limit ring 121 and is connected to the limit plate 123 through the connector 4, ensuring that the cylinder 8 will not loosen or fall off during the disassembly and assembly process, which can further enhance the stability of the installation of the cylinder 8. Furthermore, the connector 4 is a threaded rod, and there are multiple of them.

[0060] The fixing ribs 122 are usually in the shape of a triangle or a trapezoid and have good mechanical properties. They are evenly distributed between the stop ring 121, the stop plate 123 and the support base plate 11 and fixed together by welding or bolting to ensure that the stop ring 121 can be firmly fixed on the support base plate 11 and will not be deformed or damaged when bearing the weight and external force of the cylinder 8.

[0061] A fixing sleeve 5 is provided on the outer circumference of the limiting ring 121 , and the fixing sleeve 5 is used to fix the adjusting member 3 .

[0062] In this technical solution, the fixing sleeve 5 is installed on the outer circumference of the limiting ring 121, and its size matches that of the adjusting member 3, which can ensure that the adjusting member 33 will not shake or move during operation.

[0063] During the disassembly and assembly of the cylinder 8, the adjusting member 3 needs to bear a large force and pressure to drive the pressing plate 2 to move along the axial direction of the cylinder 8. The function of the fixing sleeve 5 is to provide a stable support point for the adjusting member 3 so that it can function effectively. The internal structure of the fixing sleeve 5 perfectly matches the shape of the adjusting member 3, ensuring that the adjusting member 3 can maintain the correct position and direction during operation.

[0064] Furthermore, the fixing sleeve 5 includes a fixing block 51, a collar 52 and a screw 53. The fixing block 51 is installed on the outer circumference of the limiting ring 121, and the collar 52 is installed on the fixing block 51 through the screw 53. The collar 52 can limit and fix the adjusting member 3, and is also convenient for disassembly to realize the inspection and replacement of the adjusting rod.

[0065] The number of the adjusting members 3 is three, and they are arranged on the supporting base plate 11 in a triangular structure.

[0066] In this technical solution, the adjusting member 3 is installed on the supporting base plate 11 in a triangular shape. First, the triangular structure is stable. The distribution of the three adjusting members 3 forms a stable triangular supporting system, which can provide a more stable supporting force during the disassembly and assembly of the cylinder 8. This structure can effectively resist external forces from all directions, ensuring that the tooling will not shake or tilt during operation, thereby improving the safety and accuracy of the operation.

[0067] Secondly, the arrangement of the three adjusting members 3 can distribute the pressure more evenly. When compressing the cylinder 8 or releasing the pressure of the spring 83, the three adjusting members 3 can act simultaneously, so that the pressure is more evenly transmitted to the pressure plate 2, and then acts on the cylinder 8. This can avoid deformation or damage of the cylinder 8 due to uneven pressure, and ensure the integrity and performance of the cylinder 8.

[0068] In addition, the adjustment member 3 arranged in a triangular structure is also easy to operate and control. The operator can achieve precise movement of the pressure plate 2 by synchronously adjusting the three adjustment members 3, thereby better controlling the pressure release process of the spring 83 inside the cylinder 8. At the same time, this structure also makes the overall layout of the tooling more reasonable, occupies less space, and is convenient for use in different working environments.

[0069] The adjusting member 3 is an oil cylinder.

[0070] It also includes a hydraulic pump 6 , which is connected to the adjusting member 3 and is used to provide power for the adjusting member 3 .

[0071] In this technical solution, the oil cylinder is used as the adjusting part 3, and its powerful thrust and precise stroke control ability bring great convenience to the disassembly and assembly operation of the cylinder 8. The oil cylinder can withstand high pressure to ensure that there is sufficient force when compressing the cylinder 8 or releasing the pressure of the spring 83. At the same time, the movement of the oil cylinder can be precisely controlled by the hydraulic system, so that the movement of the pressure plate 2 is more stable and accurate, thereby improving the accuracy and reliability of the disassembly and assembly operation. A synchronizer is installed on the hydraulic pump 6. When the hydraulic pump 6 is started, the synchronizer allows multiple adjusting parts 3 to maintain synchronous lifting and lowering functions, ensuring stability and improving safety during maintenance.

[0072] As a power source, the hydraulic pump 6 provides stable and powerful power support for the operation of the oil cylinder. The hydraulic pump 6 can adjust the output pressure and flow rate according to actual needs to meet the disassembly and assembly requirements of cylinders 8 of different specifications. It has the characteristics of fast response speed and high output power, and can quickly provide the required hydraulic power to the oil cylinder, thereby improving work efficiency. In addition, the hydraulic pump 6 can also be remotely operated through the control system, which is convenient for operators to operate in a safe position and reduces operational risks.

[0073] It also includes a moving trolley 7, and the hydraulic pump 6 is arranged on the moving trolley 7.

[0074] In this technical solution, the mobile trolley 7 provides a movable platform for the hydraulic pump 6. Generally, the mobile trolley 7 has a solid structure and flexible mobility, and can be easily moved in the workplace. This makes the disassembly and assembly of the entire cylinder 8 more flexible, not limited by a fixed position, and the position can be adjusted at any time according to actual needs, thereby improving work efficiency. The hydraulic pump 6 is arranged on the mobile trolley 7, which facilitates the operation and maintenance of the hydraulic pump 6. The operator can easily push the mobile trolley 7 to a suitable position according to work requirements, and perform operations such as starting, adjusting and monitoring the hydraulic pump 6. At the same time, when the hydraulic pump 6 needs to be maintained or overhauled, it can also be easily removed from the mobile trolley 7 for more convenient maintenance work. In addition, the mobile trolley 7 can also provide certain protection for the hydraulic pump 6. In the workplace, there may be various debris and collision risks. The mobile trolley 7 can isolate the hydraulic pump 6 from the surrounding environment and reduce the damage to the hydraulic pump 6 caused by external factors. At the same time, some protective devices, such as protective covers, anti-collision strips, etc., can also be arranged on the mobile trolley 7 to further improve the safety of the hydraulic pump 6.

[0075] The application principle is:

[0076] When disassembling the cylinder 8, install the cylinder 8 on the base 1, connect and fix the connecting end 85 to the limit plate 123 through the connecting piece 4, connect the pressure plate 2 to the top of the adjusting piece 3 through the plug-in rod 23, and the pressure plate 2 is located above the top plate 84 of the cylinder 8. Disassemble the fixing screw 86 and the nut 87 on the cylinder 8. At this time, the top plate 84 is tightly attached to the pressure plate 2 driven by the spring 83. The staff drives the telescopic end of the adjusting piece 3 to extend by controlling the hydraulic pump 6, and slowly releases the elastic force of the spring 83. After the release, remove the plug-in rod 23 from the fixing seat 22, remove the pressure plate 2, and then remove the top plate 84 and the spring 83 of the cylinder 8 to complete the disassembly of the cylinder 8.

[0077] When installing the cylinder 8, the connecting end 85 is fixed with the limit plate 123 through the connecting piece 4, so that the bottom plate 81 and the cylinder body 82 are fixed on the base 1, and the spring 83 is placed in the cylinder body 82, and the top plate 84 is prevented from being pressed on the top of the spring 83. The length of the telescopic end of the adjusting member 3 is adjusted by the hydraulic pump 6 to be above the top plate 84, and then the pressure plate 2 is installed on the adjusting member 3. At this time, the length of the telescopic end of the adjusting member 3 is adjusted by the hydraulic pump 6, and the pressure plate 2 is driven to move slowly toward the cylinder body 82 until the top plate 84 contacts the cylinder body 82, that is, the spring 83 is compressed into the inside of the cylinder body 82, and then the fixing screw 86 and the nut 87 are installed on the bottom plate 81 and the pressure plate 2 to complete the installation of the cylinder 8.

[0078] The present application fixes the cylinder 8 through the base 1, and the adjustment member 3 drives the pressure plate 2 to extend and retract, so that the cylinder 8 can be disassembled, and the disassembly efficiency is high, the safety and stability are good, and the operation can be completed by one person, saving manpower and material resources.
