[0002] In terms of the maintenance of hydraulic cylinders for coal mine hydraulic supports, traditional fixed structures have many drawbacks: on the one hand, the clamping cylinder is difficult to disassemble quickly, and the relevant components need to be disassembled as a whole during maintenance, which is time-consuming and labor-intensive and increases the risk of misoperation, thus leading to a significant extension of equipment downtime for maintenance; on the other hand, operators need to use wrenches and other tools to work while bending over for a long time, which can easily cause occupational injuries such as lumbar muscle strain, and the risk of bolts loosening and falling off is high.

[0003] In summary, how to provide a device that can overcome the above-mentioned technical problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a small-diameter horizontal cylinder loader for repairing hydraulic support cylinders in coal mines.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A small-diameter horizontal cylinder assembly machine for repairing hydraulic support cylinders in coal mines includes a workbench. A connecting plate is fixedly connected to the upper surface of the workbench. A support plate is fixedly connected to one end of the connecting plate relative to the workbench. A hinge is provided on one side of the support plate. An upper clamping plate is provided at one end of the hinge relative to the support plate. A lower fixing plate is fixedly connected to one end of the support plate. An upper fixing plate is fixedly connected to one side of the upper clamping plate. A bolt is provided in a through hole at the upper end of the upper fixing plate.

[0024] The core of this utility model is to provide a small-diameter horizontal cylinder assembly machine for repairing hydraulic support cylinders in coal mines. The following will be combined with… Figures 1-4 A detailed description of each component that makes up the device is provided below:

[0025] This small-diameter horizontal cylinder assembly machine for repairing hydraulic support cylinders in coal mines includes a workbench 1. A connecting plate 2 is fixedly connected to the upper surface of the workbench 1. A support plate 3 is fixedly connected to one end of the connecting plate 2 relative to the workbench 1. A hinge 4 is provided on one side of the support plate 3. An upper clamping plate 5 is provided at one end of the hinge 4 relative to the support plate 3. A lower fixing plate 6 is fixedly connected to one end of the support plate 3. An upper fixing plate 7 is fixedly connected to one side of the upper clamping plate 5. A bolt 8 is installed in a through hole at the upper end of the upper fixing plate 7. Specifically, the hinge 4 can drive the upper clamping plate 5 to rotate, thereby fixing the hydraulic cylinder structure. The bolt 8 can pass through the upper fixing plate 7 and the lower fixing plate 6 to fix the upper clamping plate 5 to the support plate 3. This eliminates the cumbersome process of disassembling and assembling bolts one by one. The hinge lever principle enables rapid pushing and positioning of the hydraulic cylinder. Combined with the one-button locking function of the quick-release bolts, it significantly shortens the equipment debugging and replacement time, making it particularly suitable for frequent switching scenarios with multiple cylinder diameters and significantly improving continuous operation capability.

[0026] The lower surface of the workbench 1 is provided with multiple support feet 9; specifically, the support feet 9 serve as the bottom support structure of the whole machine, and are fixed to the ground to ensure the stability of the cylinder loading machine, distribute the pressure during the operation of the equipment, and avoid shaking that affects the assembly accuracy.

[0027] An emulsion pump station 10 is fixedly connected to one side of the upper surface of the workbench 1, and a clamping cylinder 11 is provided on one side of the emulsion pump station 10. Specifically, the clamping cylinder 11 provides a power source and drives the hydraulic system by conveying high-pressure emulsion, thereby providing power to the clamping cylinder and other actuators to realize mechanized assembly actions.

[0028] The upper surface of the workbench 1 is provided with a cylinder lug 12 at one end relative to the emulsion pump station 10. Specifically, the cylinder lug 12 is the core execution component, which uses hydraulic thrust to precisely press the piston, guide sleeve and other parts into the piston rod or cylinder, replacing manual hammering and improving assembly efficiency and safety.

[0029] A cylinder body 13 is provided on one side of the cylinder body lug 12; specifically, the cylinder body 13 serves as the main structure of the hydraulic cylinder, used to accommodate the piston rod assembly, and is press-fitted by a cylinder assembler to form a complete hydraulic cylinder, thereby realizing the support function of the hydraulic support in the coal mine.

[0030] The upper surface of the workbench 1 is provided with multiple side plates 14, and a cylinder support U-shaped seat 15 is provided on one side of each side plate 14. Specifically, the side plates 14 are installed on both sides of the cylinder support mechanism and have multiple grooves to accommodate cylinders of different diameters up to 160mm. The cylinders of various specifications can be fixed by adjusting their positions in the grooves. The cylinder support U-shaped seat 15 supports the cylinder to be assembled and provides a support and positioning surface. Its removable U-shaped baffle at the front facilitates the pre-assembly of the piston, guide sleeve, and piston rod, improving assembly convenience.

[0031] A screw 16 is provided at the upper end of the cylinder support U-shaped seat 15 through a through hole; specifically, the screw 16 can be combined with the cylinder support U-shaped seat 15 to ensure the stable fixation of the cylinder 13, thereby making the overall structure stable.

[0032] A piston 17 is housed inside the cylinder body 13, and a guide sleeve 18 is provided at one end of the piston 17. Specifically, the piston 17 is a key moving component inside the cylinder, forming a sealed cavity with the cylinder body. It achieves linear motion by being driven by hydraulic oil, transmitting power to the hydraulic support. The guide sleeve 18 is installed on the outside of the piston rod 19, providing guidance and support for the piston rod, ensuring the straightness of the piston rod's reciprocating motion, and preventing hydraulic oil leakage through a seal.

[0033] A piston rod 19 is provided on one side of the guide sleeve 18; specifically, the piston rod 19 is connected to the piston 17 and transmits power. It is pressed into the cylinder by the cylinder assembler and together with the piston and guide sleeve, it forms a motion assembly that converts hydraulic energy into mechanical energy.

[0034] In summary: Hinge 4 allows the upper clamping plate 5 to rotate, thereby fixing the hydraulic cylinder structure. Bolt 8 passes through the upper fixing plate 7 and the lower fixing plate 6 to fix the upper clamping plate 5 to the support plate 3. This eliminates the tedious process of manually removing and installing bolts one by one. The hinge lever principle enables rapid movement and positioning of the hydraulic cylinder. Combined with the one-button locking function of the quick-release bolts, it significantly shortens equipment debugging and replacement time, making it particularly suitable for scenarios with frequent switching of multiple cylinder diameters and significantly improving continuous operation capability.
