Technical Field

[0001] The utility model relates to the technical field of hydraulic cylinder maintenance, in particular to a special tooling for hydraulic cylinder maintenance. Background Technique

[0002] As an important actuator in the hydraulic system, the hydraulic cylinder is widely used in various mechanical equipment to achieve linear reciprocating motion. During the use of the hydraulic cylinder, due to its harsh working environment, large working load, and aging of seal materials, etc., the problem of seal failure often occurs. Therefore, appropriate maintenance methods and tooling are required to disassemble, replace, and install the seals.

[0003] As the core component of the hydraulic tensioning system, due to the differences in belt technical parameters, there are many types of hydraulic cylinders to be adapted. And under the long-term high-load operation of these hydraulic cylinders, their internal seals are prone to aging or damage, resulting in system pressure loss or insufficient pressure holding capacity, seriously affecting the normal operation and production efficiency of the belt conveyor. The precision of the internal components of the hydraulic cylinder determines its high maintenance difficulty. The existing technologies generally rely on multiple professional personnel and many operating devices for maintenance. If external maintenance is relied on every time it is damaged, not only the maintenance cycle is long, but also the on-site production efficiency is severely restricted, which will have an adverse impact on the overall benefit.

[0029] Further, there are two sets of movable blocks 317, which are symmetrically arranged outside the bidirectional screw 314. Through holes are provided at the corresponding positions of the movable blocks 317 and the guide rods 316, and the guide rods 316 penetrate through the through holes. The top of the connecting plate 318 is rotatably installed with the slider 3110, which is convenient for stably adjusting the height of the channel steel plate 312 and improving the support for the hydraulic cylinder.

[0030] Further, the auxiliary positioning component 32 includes a mounting frame 321. The mounting frame 321 is fixedly installed with a mounting post 322. An adjusting frame 323 is rotatably installed outside the mounting post 322. A first positioning rubber wheel 324 is rotatably installed inside the adjusting frame 323.

[0032] Embodiment 2:

[0033] Please refer to Figure 5 , and in combination with Embodiment 1, it is further obtained that the adjusting support mechanism 4 includes a movable bottom plate 41. A connecting handle 42 is fixedly installed outside the movable bottom plate 41. A guide block 43 is fixedly installed at the bottom of the movable bottom plate 41. A rib plate 44 is fixedly installed on the top of the channel steel plate 312. A clamping plate 45 is inserted and installed outside the rib plate 44.

[0034] Further, a limiting chute is provided at the corresponding position of the top of the mounting bottom plate 1 and the guide block 43, and the guide block 43 is slidably installed inside the limiting chute.

[0035] In the actual operation process, when this device is in use and the hydraulic cylinder needs to be repaired, first, according to the diameter of the hydraulic cylinder to be repaired, the connecting handle 42 can be pushed to move the movable bottom plate 41, so as to change the distance between the two grooved steel plates 312. Subsequently, to ensure the support of the hydraulic cylinder, the height of the two grooved steel plates 312 can be adjusted. By rotating the adjusting handle 315, the bidirectional screw 314 rotates. Under the action of the guide rod 316, the arranged movable block 317 can move outside the bidirectional screw 314, so that the connecting plate 318 rotates, and thus the slider 3110 slides outside the guide rail strip 319 to change the height of the grooved steel plate 312. When the height reaches the required value, the hydraulic cylinder can be limited by the two grooved steel plates 312. Subsequently, to ensure the limiting effect on the hydraulic cylinder, the telescopic cylinder 325 can be opened to push the special-shaped block 326 to contact the first positioning rubber wheel 324 inside the adjusting frame 323, so that the adjusting frame 323 rotates, and the two adjusting frames 323 rotate centrally. Under the action of the other first positioning rubber wheel 324, the hydraulic cylinder can be assisted in positioning. Under the action of the second positioning rubber wheel 328, the tight contact effect can be ensured, so as to facilitate the later work of disassembling and replacing the sealing parts and pistons of the hydraulic cylinder. Subsequently, the clamping plate 45 can be placed outside the two rib plates 44 to form an insertion connection with the rib plates 44, and then the jack can be placed on the top of the jack support seat 46 to perform the operation of replacing the sealing parts and pistons of the hydraulic cylinder.
