In addition, a lifting roller 800 is also provided at the front end of the first support table 100, and the support for the piston rod 202 at different heights is realized through a liftable structure to ensure that it is pumped always on the same level during distance and installation. The specific structure is as follows:

The hydraulic cylinder 200 has a cylinder barrel 201 and a piston rod 202. Due to different product models, the dimensions (ie, length and diameter) of the hydraulic cylinder 200 will be different. This hydraulic cylinder auxiliary disassembly mechanism can be applied to various models. Hydraulic cylinders of size 200 are used.

The first support table 100 is generally a rectangular table top structure, which has an assembly table 1 101 located horizontally at the upper part, and has an accommodating space for accommodating objects (mainly used for placing the first oil drum 001, the second oil drum 001, the second oil tank barrel 002 and hydraulic station 003), an oil groove 104 is formed on the upper surface of the assembly table 101 along its length direction, one end of the oil groove 104 is guided to the first oil barrel 001 through the first oil passage 102, and the other end is guided to the first oil barrel 001. The second oil barrel 002 is guided through the second oil passage 103. The hydraulic station 003 is arranged between the first oil barrel 001 and the second oil barrel 002. The hydraulic station 003 is used to connect the oil cylinder 700, and the oil cylinder 700 is horizontal Installed below the assembly table one 101. An idler 1 400 is installed on the upper end surface of the first assembly table 101 , specifically, a row of idler groups formed by one idler group formed by every two idler rollers 400 , that is, in the Two idlers one 400 are symmetrically arranged in the width direction of the assembly table one 101. These two idler rollers one 400 are arranged obliquely and present a V shape. The idler group is used to support the cylinder tube 201 .

Here, those skilled in the art can understand that two idlers 1 400 constitute a set of idlers and are arranged at a preset angle of inclination. The purpose of such a structure is to adapt to cylinders 201 of various sizes and structures, and at the same time There are multiple groups arranged in the length direction, so that the hydraulic cylinder 200 only needs to be placed on the idler 1 400 and can be horizontally and smoothly displaced along the length direction of the assembly table 1 101, so as to adjust the position, more specifically Said one end of the idler 1 400 is connected to the middle of the assembly table 1 101 , and the other end is raised to a certain height and fixed by the support frame 2 401 , and the bottom of the support frame 2 401 is fixed at the bottom of the assembly table 1 101 edge.

The limit blocks (ie the first limit block 341 and the second limit block 342 ); the threaded rod 310 drives the inner sides of the two limit blocks to fit or drive away from the side wall of the cylinder 201 through threaded rotation.

Here, those skilled in the art can understand that the anti-jump device 300 is used to achieve the function of limiting or not limiting the position through the position of the two limit blocks relative to the cylinder 201. Generally speaking, when the hydraulic pressure When the oil cylinder 200 is not placed on the roller one 400, the limit block at this time is located at a higher position. When the end of the cylinder barrel 201 is connected and fixed by the positioning device 500, the two limit blocks are driven by rotating the threaded rod 310. The inner side of the block is attached to the side wall of the cylinder barrel 201 to achieve the limiting effect and prevent the problem of warping during the stretching of the piston rod 202 .

In addition, it should be noted that the used limiter is set to open at a preset inclination angle, and its function is similar to the inclined setting of the idler-400.
