[0023] For a better explanation of this application and for easier understanding, the following will describe this application in detail through specific embodiments in conjunction with the accompanying drawings. The orientation nouns such as "upper" and "lower" mentioned in this article are referenced with the Figure 1 orientation of Figure 1 . The position of the cylinder block 6 relative to the cylinder bottom 61 is defined as "upper".

[0024] As described above, an oil cylinder, also known as a hydraulic cylinder, generally consists of a cylinder barrel, a cylinder bottom, a plunger, seals, etc. Its working principle is that when the liquid is pressurized in the cylinder, it will push the moving parts such as the plunger to move along the axis of the cylinder barrel, and rely on the linear reciprocating motion of the plunger in the cylinder barrel to achieve energy conversion, thereby converting hydraulic energy into mechanical energy.

[0025] The long-term use of the oil cylinder will cause wear on the surface of the plunger, which will in turn affect its sealing performance and accuracy. When the wear is severe, it may cause oil leakage or failure of the oil cylinder. The seals will come into frequent contact and friction with components such as the plunger and the cylinder barrel during the operation of the oil cylinder, resulting in wear. The worn seals cannot effectively prevent the leakage of hydraulic oil, reducing the system efficiency. Therefore, it is necessary to regularly check the sealing performance and wear condition of the oil cylinder plunger and seals, and replace the damaged components in time.

[0026] During the maintenance of the oil cylinder plunger and seals, a jack needs to be placed directly below the oil cylinder for jacking and fixing. However, during actual disassembly and maintenance, space needs to be left for part replacement, and placing the jack cannot leave enough operating space, which cannot guarantee the maintenance efficiency of the oil cylinder and the safety of personnel.

[0027] To solve at least one of the technical problems existing in the prior art or related technologies, this application provides an oil cylinder maintenance device, including: a plurality of support rods, one end of the support rod is detachably connected to the cylinder barrel; a lowering mechanism is provided on the support rod, and the lowering mechanism is used to control the cylinder bottom to descend to a preset height after the cylinder bottom is separated from the cylinder barrel. Install the support rod in the mounting hole of the cylinder barrel; adjust the lowering mechanism to make the cylinder bottom descend to the preset height. When the cylinder bottom descends to an appropriate height, the plunger and seals are maintained, which can leave enough space for part replacement and can also guarantee the safety of personnel.

[0028] The following describes an oil cylinder maintenance device according to some embodiments provided by this application with reference to the accompanying drawings.

[0029] See Figures 1 to 3 , an oil cylinder maintenance device provided by the first aspect embodiment of this application includes: a plurality of support rods 1, one end of the support rod 1 is detachably connected to the cylinder barrel 6; a lowering mechanism 2 is provided on the support rod 1, and the lowering mechanism 2 is used to control the cylinder bottom 61 to descend to a preset height after the cylinder bottom 61 is separated from the cylinder barrel 6.

[0030] When maintaining the oil cylinder, it needs to be placed vertically. One end of the support rod 1 is connected to the cylinder body 6. The support rod 1 plays a supporting role, supporting the cylinder body 6 to a certain height to facilitate maintenance operations. Adjust the lowering mechanism 2 to separate the cylinder bottom 61 from the cylinder body 6 and lower it to a preset height. When the cylinder bottom 61 is lowered to an appropriate height, the plunger and seals can be maintained, leaving enough space for part replacement.

[0031] In a schematic embodiment, one end of the support rod 1 is provided with a thread, and the bottom of the cylinder body 6 is provided with a mounting hole 63. The support rod 1 is detachably connected to the mounting hole 63 through the thread.

[0032] There are mounting holes 63 evenly distributed in a ring at the bottom of the cylinder body 6, and the mounting holes 63 are used for the installation of the oil cylinder. One end of the support rod 1 is provided with a thread matching the mounting hole 63. Through the thread, the support rod 1 can be tightly connected to the cylinder body 6. This connection method has high stability and load-bearing capacity. The tightening of the thread can generate sufficient pre-tightening force to ensure that the support rod does not loosen or fall off when supporting the cylinder body. The detachable connection between the support rod 1 and the cylinder body 6 makes the maintenance work more flexible and convenient. When it is necessary to overhaul the oil cylinder, replace components or perform other maintenance operations, the support rod 1 can be easily disassembled. The design of the thread reduces the complexity and time cost of maintenance work, and also reduces the risk of production interruption caused by maintenance.

[0033] Moreover, the detachable connection between the support rod 1 and the cylinder body 6 enables the device to adapt to different working environments and requirements. For example, when it is necessary to adjust the height or position of the cylinder body 6, it can be achieved by replacing support rods 1 of different lengths. The threaded connection can also fine-tune the support rod 1 when necessary to ensure that the cylinder body 6 is in the best working state.

[0034] In a schematic embodiment, the number of support rods 1 is at least three. Three or more support rods 1 can form a stable support plane or frame, which can effectively prevent the cylinder body 6 from tilting or shaking when subjected to external forces. Moreover, three or more support rods 1 can more evenly share the weight and load of the cylinder body 6, reducing the stress concentration on a single support rod 1, thereby extending its service life.

[0035] In a schematic embodiment, the lowering mechanism 2 is a nut. The support rod 1 is provided with a matching slow descent thread. The nut is arranged below the cylinder bottom 61 and can play a role in supporting the cylinder bottom 61. By adjusting the nut, the cylinder bottom 61 can be slowly lowered to a preset height.

[0036] Compared with conventional threads, the slow - descent thread has a finer pitch or a special shape to provide a smoother and more controllable descent speed during rotation. The design of the slow - descent thread and nut makes the descent process of the cylinder bottom 61 very smooth, reducing impact and vibration, which is beneficial to protecting the cylinder bottom 61 and its internal components. By precisely controlling the rotation of the nut, precise adjustment of the descent position of the cylinder bottom 61 can be achieved to meet the requirements of various maintenance operations.

[0037] In a schematic embodiment, the oil cylinder maintenance device further includes: a fixing plate 3. When the plunger 62 is exposed from the cylinder block 6, the fixing plate 3 is arranged in the groove of the plunger 62, and the fixing plate 3 is detachably connected to the cylinder block 6; the fixing plate 3 is used to limit the movement of the plunger 62.

[0038] After the cylinder bottom 61 is separated from the cylinder block 6, the plunger 62 will be exposed from the cylinder block 6. To prevent the plunger 62 from falling, the fixing plate 3 is inserted into the groove of the plunger 62 and fixed to the cylinder block 6, so that the plunger 62 can be fixed, facilitating maintenance.

[0039] In a schematic embodiment, the fixing plate 3 is detachably connected to the mounting hole 63 of the cylinder block 6 by bolts.

[0040] When the cylinder bottom 61 descends to a preset height, the fixing plate 3 is inserted into the groove matching the plunger 62 to limit the up - and - down movement of the plunger 62, and the fixing plate 3 is fixed to the mounting hole 63 of the cylinder block 6 by bolts. Through the locking mechanism of the fixing plate 3 and the bolts, it can be ensured that the cylinder block 6 and the plunger 62 maintain a stable relative position for a long time, reducing the position offset caused by vibration or external force, facilitating maintenance operations, and ensuring the safety of operators at the same time.

[0041] Furthermore, the number of the fixing plates 3 is at least two. Two or more fixing plates 3 can provide a more uniform supporting force, reducing the concentration of single - point stress, thereby enhancing the stability between the cylinder block 6 and the plunger 62, and helping to prevent loosening or offset caused by vibration, impact or external force; moreover, as the number of the fixing plates 3 increases, the load - bearing capacity of the entire fixing structure will also increase accordingly. During the fixing process, multiple fixing plates can more effectively disperse stress, reducing the local pressure on the cylinder block 6 and the plunger 62, helping to extend the service life of the equipment and reduce the risk of damage; at the same time, using multiple fixing plates 3 can also improve safety. Even if one fixing plate 3 fails or malfunctions, the other fixing plates 3 can still continue to work, ensuring the safety and stability of the cylinder block 6 and the plunger 62.

[0042] In a schematic embodiment, as Figure 2As shown, a leveling mechanism 4 is provided at one end of the support rod 1 away from the cylinder block 6. Further, the leveling mechanism 4 is a leveling foot, and the leveling foot is provided at one end of the support rod 1 away from the cylinder block 61 in a threaded manner. When there is a height difference among multiple support rods 1 due to different ground heights, the thread of the leveling foot can be adjusted to extend or shorten the leveling foot, and height adjustment is achieved through the thread to adapt to ground of different heights. This adjustment method is flexible and convenient, and can quickly reach the required level state. Threaded connection is easy to disassemble and install, facilitating maintenance and replacement. The leveling foot can be provided with different lengths to adapt to the unevenness of different terrains or work surfaces.

[0043] In a schematic embodiment, the oil cylinder maintenance device further includes: a safety rope 5, one end of the safety rope 5 is detachably connected to the cylinder block 6, and the other end is detachably connected to the cylinder bottom 61.

[0044] The safety rope 5 can be detachably connected to the cylinder block 6 and the cylinder bottom 61 by means of hooks, buckles, bolts, etc. The safety rope 5 is used to prevent the cylinder bottom 61 from accidentally falling off or tipping over during the maintenance of the oil cylinder, thereby protecting the safety of operators and equipment. The detachable connection method enables the safety rope 5 to be easily installed or disassembled as needed, improving flexibility and usage efficiency.
