[0021] Example

[0022] Please see Figure 1-2 This utility model provides a technical solution:

[0023] An installation tool for conveniently replacing the air valve of a reciprocating machine is provided. The main body 1 has a fixed flange 2 welded to its bottom and a constraint plate 3 on its top. The constraint plate 3 has a through hole inside and a telescopic screw 4 is coaxially installed inside the through hole. A control handle 5 is provided above the telescopic screw 4. An inner groove 6 is welded to the bottom of the telescopic screw 4 and a disassembly buckle 7 is provided at the bottom of the inner groove 6. The fixed flange 2 has several through holes on its exterior and flange threads inside the several through holes.

[0024] The main body, a cylindrical structure, forms the core of the tool. A flange is welded to the bottom of the main body, and the flange has multiple through holes with flange threads for connection to the cylinder flange, ensuring the tool's stability and robustness. The flange is bolted to the cylinder, with 10mm bolt holes.

[0025] The constraint plate is located at the top of the main body and its function is to fix it to the main body by welding. The constraint plate has a coaxial through hole inside, within which is installed a telescopic screw. This screw features a multi-segment adjustable design, facilitating length adjustment to accommodate different specifications of air valves. Each segment of the screw is connected by a thread with an M12×1.5 thread specification, ensuring precise adjustment of the screw. The forward and backward movement of the telescopic screw is achieved by rotating the control handle.

[0026] The upper end of the telescopic lead screw is fixed to the control handle via a threaded connection. The control handle features a T-shaped design, allowing the operator to apply sufficient torque to rotate the lead screw. By rotating the control handle, the extension and retraction of the lead screw can be adjusted, thereby driving other parts of the tool to disassemble and install the air valve.

[0027] The inner groove, located at the bottom of the telescopic screw, has a ring-shaped structure with multiple protrusions at the bottom. It engages with the disassembly inner clip to ensure stable connection during valve installation and disassembly. The inner groove is fixedly connected to the disassembly inner clip via internal and external threads. The internal thread specification is M10×1.0, ensuring a secure connection between all tool components and preventing loosening during operation.

[0028] During valve disassembly, first, secure the tool's fixing flange to the cylinder with bolts. Then, rotate the control handle to extend the telescopic screw, connecting to the end of the valve. Once the valve is completely removed from the cylinder and in its inner groove, operators can use a crane or chain hoist to lift it out for maintenance. After maintenance, use a crane or chain hoist to re-lift the valve into the cylinder, then rotate the control handle to push the valve back into the cylinder, ensuring stable installation.

[0029] The working principle of this technical solution is based on the threaded and screw-driven propulsion principle. The telescopic screw moves back and forth by rotating the control handle, thereby facilitating the disassembly and installation of the air valve. When the operator rotates the control handle, the telescopic screw extends outward, removing the air valve from the cylinder. At this time, the air valve is firmly supported by the inner groove, preventing the air valve from falling off or becoming unstable. After disassembly, the operator can use a crane or chain hoist to lift the air valve out for maintenance. After maintenance, the telescopic screw is rotated again using the control handle to push the air valve back into the cylinder for installation, and it is fixed to the cylinder via flange threads, ensuring a secure installation of the air valve.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
