Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of diaphragm compressor overhaul, specifically to an assembled hoisting structure for overhauling the cylinder head of a diaphragm compressor. Background Technology
[0002] A diaphragm compressor, also known as a membrane compressor, is a type of reciprocating compressor among positive displacement compressors. It uses hydraulic power to drive the diaphragm. It consists of a hydraulic system and a gas compression system. The forward-moving piston causes hydraulic oil to impact the bottom of the diaphragm, compressing the cavity and expelling the process gas. It has been widely used in laboratory research, the petroleum and gas industry, the chemical industry, the metallurgical industry, the pharmaceutical industry, and the power industry.
[0003] The diaphragm and cylinder head of a diaphragm compressor are critical components. When a malfunction occurs during use, the diaphragm needs to be replaced or the cylinder head needs to be disassembled. Replacing the diaphragm requires removing the cylinder head cover; if the main drive malfunctions, the cylinder head must be removed. Because the cylinder head is quite heavy, it is very difficult for users to inspect and disassemble it when there is no overhead crane or hoist at the site. Therefore, these issues need to be addressed. Summary of the Invention
[0004] The purpose of this invention is to provide an assembled hoisting structure for overhauling the cylinder head of a diaphragm compressor, thereby overcoming the aforementioned defects in the prior art.
[0005] An assembled hoisting structure for overhauling the cylinder head of a diaphragm compressor includes a manual hoist, a support arm, a lifting ring, a rotating assembly, and a limiting assembly. The support arm has an inverted "L" shape and is rotatably connected to the rotating assembly on the compressor's base skid. The upper end of the support arm is provided with a welded nut. The lifting ring is provided with a screw threadedly connected to the welded nut. The hook at the top of the manual hoist is hung in the lifting ring. The limiting assembly is provided on the support arm and the rotating assembly and is used to limit the movement of the support arm and the rotating assembly.
[0006] Preferably, the rotating assembly includes a support column, a cover plate, and a thrust bearing. The lower end of the support column is located on the base plate of the compressor skid and the top of the support column is provided with a cover plate. The side of the support column is provided with an oil inlet. The outer side of the support column is connected to a fixing plate on the compressor skid. The support arm is inserted into the cover plate and the support column, and its lower end is rotatably connected to the lower end of the support column through a thrust bearing. The support arm is rotatably connected to the upper side of the support column through an upper bearing.
[0007] Preferably, the limiting component includes a stop plate, a stop disc, and a locking pin. The stop plate has two stop plates symmetrically arranged on the side of the support arm and has a stop hole one on it. The stop disc is arranged on the support column and has several stop holes two evenly distributed along its circumference. The locking pin has an inverted "L" shaped structure and is inserted into the stop hole one and the stop hole two.
[0008] Preferably, the support arm is provided with a rotating handle on its side.
[0009] Preferably, the support arm has a slanted arm on its side.
[0010] The beneficial effects achieved by this utility model are as follows:
[0011] This application allows for easy lifting of the cylinder head of the diaphragm compressor using a manual hoist. The position of the cylinder head can be easily adjusted by directly rotating the handle. A locking pin secures the support arm in a fixed position, increasing the stability of the device.

[0018] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of this utility model, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solution of this utility model.
[0019] like Figure 1-5As shown, this utility model provides an assembled hoisting structure for overhauling the cylinder head of a diaphragm compressor, including a manual hoist 5, a support arm 1, a lifting ring 4, a rotating assembly 2, and a limiting assembly 6. The support arm 1 has an inverted "L" shape and is rotatably connected to the rotating assembly 2 on the compressor base skid. The support arm 1 has a rotating handle 11 on its side, which facilitates the rotation of the support arm 1. The support arm 1 has a slanted arm 12 on its side to enhance its strength. The upper end of the support arm 1 has a welded nut 3. The lifting ring 4 has a screw 41 threadedly connected to the welded nut 3. The hook at the top of the manual hoist 5 is hung in the lifting ring 4. The limiting assembly 6 is provided on the support arm 1 and the rotating assembly 2 and is used to limit the movement of the support arm 1 and the rotating assembly 2.
[0020] It should be noted that the rotating assembly 2 includes a support column 21, a cover plate 23, and a thrust bearing 25. The lower end of the support column 21 is located on the base plate 22 of the compressor base skid, and the top of the support column 21 is provided with a cover plate 23. The side of the support column 21 is provided with an oil inlet 211. The outer side of the support column 21 is connected to the fixing plate 24 on the compressor base skid. The support arm 1 is inserted into the cover plate 23 and the support column 21, and its lower end is rotatably connected to the lower end of the support column 21 through the thrust bearing 25. The support arm 1 is rotatably connected to the upper side of the support column 21 through the upper bearing 26.
[0021] In addition, the limiting component 6 includes a stop plate 61, a stop disc 63, and a locking pin 65. The stop plate 61 has two stop plates symmetrically arranged on the side of the support arm 1 and has a stop hole 62 on it. The stop disc 63 is arranged on the support column 21 and has several stop holes 64 evenly distributed along its circumference. The locking pin 65 has an inverted "L" shaped structure and is inserted into the stop hole 62 and the stop hole 64.
[0022] Detailed implementation methods and principles:
[0023] When in use, the cylinder head of the diaphragm compressor is lifted by the hook on the lower side of the manual hoist 5. The cylinder head of the diaphragm compressor is rotated to the corresponding position by the rotating handle 11 on the support arm 1. The locking pin 65 is inserted into the first stop hole 62 of the stop plate 61 and the second stop hole 64 of the stop plate 63 to fix the support arm 1 in a certain position and prevent it from swinging randomly.
[0024] In summary, this application can easily lift the cylinder head of the diaphragm compressor using a manual hoist 5. The position of the cylinder head of the diaphragm compressor can be easily adjusted by directly rotating the handle 11. The locking pin 65 can fix the support arm 1 in a certain position, increasing the stability of the device.
