[0002] In the hydraulic system of dump trucks, the hydraulic cylinder is one of the key components. Its installation quality directly affects the working performance and service life of the hydraulic cylinder. The traditional method of installing hydraulic cylinders usually involves using a hammer to press the cylinder body into the cylinder liner. However, the size of the new sealing ring is usually slightly larger than the piston. Using a hammer makes it difficult to install the piston and can easily damage and deform the piston, thus affecting the sealing effect. In order to solve the above problems, an improved hydraulic cylinder installation device for dump trucks has been proposed. Utility Model Content

A jack provides thrust to the piston, replacing the hammering method, allowing the piston to be installed into the cylinder liner. During the piston-cylinder liner installation process, a limiting component provides a limiting effect on one end of the piston, and an adjusting mechanism can be used to adjust the position of the cylinder liner, thereby fixing the position of the cylinder liner and facilitating the jack to push the piston into the cylinder liner, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hydraulic cylinder installation device for a dump truck, including a base, a cylinder liner, and an adjustment mechanism for installing the cylinder liner.

[0019] 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.

[0020] This utility model provides, for example Figures 1-4The diagram shows a hydraulic cylinder installation device for a dump truck, including a base 1, a cylinder liner 2, and an adjusting mechanism 3 for installing the cylinder liner 2. The adjusting mechanism 3 is mounted on the base 1, and the cylinder liner 2 is mounted on the adjusting mechanism 3 via a lug 4. A fixed bracket 5, which works in conjunction with the adjusting mechanism 3, is fixedly connected to a symmetrical position on the surface of the base 1. One end of the fixed bracket 5 is fixedly connected to a support plate 7 via a fastener 6. A jack 8, which provides thrust between the piston 11 and the cylinder liner 2 of the dump truck hydraulic cylinder, is mounted on the inner side of the support plate 7. A circular top plate 9 is mounted on the telescopic end of the jack 8. A limit component 10 is provided on the circular top plate 9, and the piston 11, which works in conjunction with the cylinder liner 2, is engaged on the inner side of the limit component 10. The device is constructed by the base 1, cylinder liner 2, adjusting mechanism 3, and fixed bracket 5. The hydraulic cylinder installation equipment for dump trucks consists of bracket 5, support plate 7, jack 8, circular top plate 9, and limiting component 10. Cylinder liner 2 is mounted on adjusting mechanism 3 via lug 4. Adjusting mechanism 3 is mounted on base 1. Fixed bracket 5 is symmetrically fixed on the surface of base 1 and cooperates with adjusting mechanism 3. Support plate 7 is fixed to one end of fixed bracket 5 by fastener 6, which facilitates the installation of jack 8 on the inner side of support plate 7. Its telescopic end is connected to circular top plate 9. Then, limiting component 10 is mounted on circular top plate 9 to lock piston 11, ensuring the stability and functionality of the equipment. The cooperation of components such as adjusting mechanism 3 and fixed bracket 5 can adapt to the installation requirements of cylinder liners 2 of different sizes. The setting of jack 8 and limiting component 10 makes the piston 11 installation process more stable and efficient.

[0021] The adjusting mechanism 3 includes a limiting groove 31, which is formed on the base 1. Slide seats 32 are slidably connected to both ends of the limiting groove 31. A drive assembly 33, which works in conjunction with the slide seats 32, is provided within the limiting groove 31. A movable plate 34 is fixedly connected to the top of the slide seats 32. One side of the upper end of the movable plate 34 is slidably connected to a fixed bracket 5. A positioning assembly 35, which provides positional fixation for the cylinder liner 2, is provided on the other side of the movable plate 34. The limiting groove 31 in the adjusting mechanism 3 is formed on the base 1, and the slide seats 32 slide within the limiting groove 31, driven by the drive assembly 33. The movable plate 34, fixed at the top of the cylinder liner 2, is slidably connected to the fixed bracket 5 on one side, and a positioning component 35 is provided on the other side to fix the position of the cylinder liner 2. When the motor body 331 in the drive group drives the bidirectional lead screw 332 to rotate, the bidirectional lead screw 332 drives the slide block 32 to move in the limiting groove 31 through the threaded sleeve 333, thereby changing the position of the movable plate 34 and the positioning component 35. This allows the installation equipment to be flexibly adjusted according to the actual position and size of the cylinder liner 2, which is convenient for installing cylinder liners 2 of different specifications, improving installation efficiency and accuracy, and reducing labor intensity.

[0022] The positioning assembly 35 includes a fixing bolt 351, one end of which is fixed to the moving plate 34. The surface of the fixing bolt 351 is threaded with a nut 352 that limits the position of the cylinder liner 2. When installing the cylinder liner 2, the lug 4 of the cylinder liner 2 is placed on the fixing bolt 351. By tightening the nut 352, the lug 4 of the cylinder liner 2 is limited, thereby fixing the position of the cylinder liner 2 on the moving plate 34. The structure is simple and easy to operate. It can reliably fix the cylinder liner 2 and ensure that the cylinder liner 2 will not be displaced when the jack 8 pushes the piston 11 into the cylinder liner 2. This ensures the installation accuracy and avoids the situation where the piston 11 is not installed properly or the cylinder liner 2 and piston 11 are damaged due to the shaking of the cylinder liner 2.

[0023] The drive assembly 33 includes a motor body 331, which is mounted on one end of the base 1 and located outside the limiting groove 31. The output shaft of the motor body 331 is connected to a bidirectional lead screw 332, one end of which is mounted in the limiting groove 31 via a bearing. A threaded sleeve 333 is embedded on the side of the slide 32, and the surface of the bidirectional lead screw 332 is threadedly connected to the inner cavity of the threaded sleeve 333. The drive assembly 33 uses the motor body 331 as a power source. After the motor starts, its output shaft drives the bidirectional lead screw 332 to rotate. Since the bidirectional lead screw 332 is threadedly connected to the threaded sleeve 333 on the side of the slide 32, the rotation of the bidirectional lead screw 332 is converted into linear movement of the slide 32 in the limiting groove 31, thereby driving the moving plate 34 on the top of the slide 32 to move, thus adjusting the position of the cylinder liner 2.

[0024] The limiting assembly 10 includes a fixing ring 101, which is fixed to the surface of the circular top plate 9. Multiple limiting blocks 102 are equally spaced on the inner side of the fixing ring 101. The inner side of the limiting blocks 102 is in contact with the surface of the piston 11. A spring 103 is fixedly connected to the outer side of the limiting blocks 102. One end of the spring 103 is fixed to the inner wall of the fixing ring 101. When the piston 11 is inserted into the inner side of the limiting block 102, the spring 103 makes the limiting block 102 fit tightly against the surface of the piston 11, thus pre-limiting the piston 11 and preventing it from shifting during the pushing process of the jack 8. This ensures that the piston 11 enters the cylinder liner 2 smoothly in the correct direction, avoiding the piston 11 tilting and damaging the piston 11, the sealing ring, or the cylinder liner 2, thereby improving the installation quality and success rate.

[0025] A slot 12 is provided at one symmetrical position on one end of the fixed bracket 5. A slider 13 is fixedly connected to the moving plate 34 at the position corresponding to the slot 12. Through the cooperation of the slot 12 and the slider 13, when the position of the cylinder liner 2 is adjusted by the adjusting mechanism 3, the slider 13 slides in the slot 12 to provide guidance and support for the moving plate 34.

[0026] A reinforcing block 14 is fixedly connected to the outside of the fixed bracket 5. One end of the reinforcing block 14 is in contact with the surface of the movable plate 34. The reinforcing block 14 can share part of the pressure borne by the fixed bracket 5, enhance the stability of the fixed bracket 5, and ensure that the installed equipment maintains good working performance during long-term use.

[0027] In practical use, when using the hydraulic cylinder installation equipment for dump trucks, first, according to the size of the cylinder liner 2 to be installed, start the motor body 331 of the adjustment mechanism 3. The motor body 331 drives the double-acting screw 332 to rotate, so that the slide 32 moves in the limit groove 31, thereby driving the moving plate 34 to adjust its position. The moving plate 34 slides in the slot 12 of the fixed bracket 5 through the slider 13 to ensure the stability of the movement. When the moving plate 34 reaches the appropriate position, put the lug 4 of the cylinder liner 2 on the fixing bolt 351 of the moving plate 34, and then tighten the nut 352 to fix the position of the cylinder liner 2 using the positioning component 35.

[0028] Next, one end of the piston 11 is placed inside the limiting assembly 10 of the circular top plate 9. The spring 103 provides elasticity so that the limiting block 102 fits tightly against the piston 11, thus limiting its position. Then, the jack 8 is operated, and the telescopic end of the jack 8 extends, pushing the circular top plate 9 to move the piston 11 toward the cylinder liner 2. Under the steady thrust of the jack 8, the piston 11 is evenly squeezed into the cylinder liner 2, completing the installation.
