[0024] The effect achieved by the entire embodiment 1 is that, when the guide sleeve of the hydraulic column jack is installed, the initial position of the placement block 11 is close to the front side of the fixing frame 1, and the hydraulic column jack to be installed is placed at the top center of the placement block 11. After the personnel support the surface of the hydraulic column jack, the second motor 8 is started. The output end of the second motor 8 can rotate forward and reverse when the placement block 11 reciprocates back and forth. When the placement block 11 slides backward along the outer surface of the two second sliding rods 9, it drives the hydraulic column jack to move between the two clamping blocks 203 and then stops driving, and the two electric telescopic rods 202 are started synchronously. The telescopic ends of the two electric telescopic rods 202 are respectively at the two ends.

This solves the problem in the background technology that the hydraulic column jack needs to be fixed to the base with multiple bolts to maintain stability during the installation of the guide sleeve. The installation and disassembly process takes a lot of time, which affects the installation speed of the guide sleeves of multiple jacks, thereby improving the installation efficiency of the hydraulic jack guide sleeve.

[0025] Example 2, as Figures 1-4 As shown, the placement block 11 is square in shape, and a positioning groove 12 is provided on the top of the placement block 11.

[0027] Working principle: When installing the guide sleeve of the hydraulic column jack, the initial position of the placement block 11 is close to the front side of the fixed frame 1, and the hydraulic column jack to be installed is placed at the top center of the placement block 11. After the personnel support the surface of the hydraulic column jack, the second motor 8 is started. The output end of the second motor 8 rotates forward and reversely when the placement block 11 reciprocates forward and backward. When the placement block 11 slides backward along the outer surface of the two second slide bars 9, it drives the hydraulic column jack to move between the two clamping blocks 203 and then stops driving.

The telescopic ends of the two electric telescopic rods 202 are respectively on the two fixed blocks 2 01 extends outward from the inner wall, and the two clamping blocks 203 slide in the corresponding slide 205 through multiple guide rods 204 respectively. The two clamping blocks 203 will respectively clamp the outer surface of the hydraulic column jack during the movement toward each other, and play a fixing role. When the first motor 3 is started, the output end of the first motor 3 drives the first threaded rod 5 to rotate forward and reverse, and the mounting plate 4 moves up and down along the outer surface of the two first slide rods 6. When the mounting plate 4 moves downward, it drives the bottom of the mounting device 7 to contact the top of the hydraulic column jack for guide sleeve installation. This part is an existing mature technology, and its principle is based on CN218816469U A device for installing a guide sleeve of a hydraulic column jack is described in detail and will not be repeated here. After the guide sleeve is installed, the telescopic ends of the two electric telescopic rods 202 are reset, and the clamping limit of the hydraulic column jack is released. The output end of the second motor 8 moves in the opposite direction. At this time, personnel only need to support the heavier hydraulic column jack. Under the rotation of the second motor 8, the placement block 11 is driven to move forward and reset, which is convenient for people to take. The second threaded rod 10 is driven by the second motor 8 to drive the placement block 11 to move between the two clamping blocks 203, which is convenient for moving the heavier jack. The telescopic ends of the two electric telescopic rods 202 are extended synchronously, driving the two clamping blocks 203 to move toward each other, which plays a clamping and fixing role, solving the problem of the hydraulic column in the background technology. During the installation of the guide sleeve of the jack, it needs to be fixed to the base with multiple bolts to maintain stability. A lot of time is spent in the installation and disassembly process, which affects the installation speed of the guide sleeves of multiple jacks, thereby improving the installation efficiency of the guide sleeves of the hydraulic jack. By fixing the slide cylinder 205 on the inner surface of the fixed block 201 near the four corners, the multiple guide rods 204 can remain stable during the sliding process. By opening a circular positioning groove 12 on the top of the placement block 11, the diameter of the positioning groove 12 is the same as the bottom diameter of the standard hydraulic jack, the hydraulic jack can be quickly positioned when placed, so that it is in the middle position, which is convenient for the two clamping blocks 203 to clamp it, thereby improving the positioning effect of the hydraulic column jack guide sleeve installation device.
