[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a hydraulic cylinder installation trolley for a roller mill, including a base frame 6, a movable frame 8 slidably connected inside the base frame 6, an opening at the top of the base frame 6, a groove inside the opening, a connecting roller 5 inserted inside the groove, and movable wheels 4 at both ends of the connecting roller 5. The movable wheels 4 and the connecting roller 5 are slidably connected to the base frame 6, and the movable frame 8 is fixedly connected to the top of the connecting roller 5. The movable wheels 4 are rotatably connected to the connecting roller 5 via bearings. In this structure, the movable wheels 4 and the connecting roller 5 can drive the movable frame 8 to move longitudinally on the base frame 6 during movement, facilitating the adjustment of the installation position of the movable frame 8 and the hydraulic cylinder 1 to be installed on the movable frame 8. Openings are provided on both sides of the groove in the base frame 6, the length of which is less than... The base frame 6 has a width, and the two ends of the connecting roller 5 are inserted into the openings. This structure can limit the movement of the connecting roller 5 without affecting its movement with the moving wheel 4. At the same time, the connecting roller 5 can support the moving frame 8, improving its load-bearing capacity. The top of the moving frame 8 is provided with a slide groove 10, and the bottom of the mounting frame 21 is provided with a slider 9. The bottom of the slider 9 is inserted into the slide groove 10, and the slider 9 and the slide groove 10 form a sliding connection. This structure can support the mounting frame 21 and the hydraulic cylinder 1 to be installed without affecting the movement of the mounting frame 21. The moving frame 8 is provided with a movable support assembly 2 and a fixed support assembly 11. The fixed support assembly 11 and the movable support assembly 2 are connected. The support assembly 2 has the same structure. A roller frame 22 is fixedly connected to the inner side of the mounting frame 21. The fixed support assembly 11 is fixedly installed, while the position of the mounting frame 21 of the movable support assembly 2 can be adjusted longitudinally. When the movable support assembly 2 is close to the fixed support assembly 11, it can support the hydraulic cylinder 1 to be installed on top. When the movable support assembly 2 is adjusted away from the fixed support assembly 11, the height of the hydraulic cylinder 1 supported by the movable support assembly 2 and the fixed support assembly 11 decreases, achieving the purpose of adjusting the installation height of the hydraulic cylinder 1. Multiple auxiliary wheels 23 are rotatably connected to the outer wall of the roller frame 22. The auxiliary wheels 23 are longitudinally and evenly distributed about the surface of the roller frame 22. The auxiliary wheels 23 in this structure can... The movable support assembly 2 and the fixed support assembly 11 are respectively distributed at both ends of the movable frame 8. The movable support assembly 2 and the fixed support assembly 11 support the hydraulic cylinder 1 to be installed. A fixed block 7 is fixedly connected to one end of the movable frame 8. An adjusting screw 3 is slidably connected to the fixed block 7. The movable support assembly 2 includes a mounting frame 21 that is slidably connected to the movable frame 8. One end of the mounting frame 21 is rotatably connected to the adjusting screw 3. An auxiliary wheel 23 is rotatably connected to the inner side of the mounting frame 21. This device can move and adjust the position of the mounting frame 21 by rotating the adjusting screw 3.This device can be manufactured using scrap channel steel, angle iron, and bearings removed from old idler rollers, thus reducing its cost.

[0019] Working principle: When using the roller mill hydraulic cylinder installation trolley, firstly, use an overhead crane to hoist the hydraulic cylinder 1 to be installed onto the auxiliary wheel 23 on top of the movable support assembly 2 and the fixed support assembly 11. Then, adjust the height of the hydraulic cylinder 1 by rotating the adjusting screw 3. The adjusting screw 3 drives the mounting frame 21 of the movable support assembly 2 to move. The closer the mounting frame 21 is to the fixed support assembly 11, the higher the hydraulic cylinder 1 will be supported. The farther the mounting frame 21 is from the fixed support assembly 11, the lower the hydraulic cylinder 1 will be supported. Then, push the movable frame 8 and the hydraulic cylinder 1 to be installed to the appropriate installation position. Then, push the hydraulic cylinder 1 to be installed, so that it rotates with the assistance of the auxiliary wheel 23. Rotate the hydraulic cylinder 1 to the anchor bolt installation position, so that the anchor bolt of the hydraulic cylinder 1 aligns with the mounting screw hole for fixing.
