A second threaded rod 33 is threadedly connected to two adjacent second threaded holes. An annular groove is provided at the top of the vertical pipe 16, and a second sealing ring 31 is fixedly connected in the annular groove. The second sealing ring 31 and the top of the vertical pipe 16 are fitted together at the bottom of the fixed cylinder 2; Connect the second hose 24 to the feed pipe 28. The pump 21 absorbs the lubricating oil inside the vertical cylinder 1 through the first hose 23 and transports it to the inside of the fixed cylinder 2 through the second hose 24 and the feed pipe 28. The cylinder 14 drives the piston 15 to move upward, and the piston 15 pushes the lubricating oil upward. The lubricating oil can then flow out from the top of the regulating pipe 4. A diverter pipe is installed on the top of the regulating pipe 4 to transfer the oil to various places in the natural gas compressor where lubricating oil needs to be added.
[0018] Working principle: Before the device starts working, the operator first selects the installation method of the device. The device has two installation methods. One is to install it through the bolts 13 on the fixing ring 9. The bottom of the device is close to the surface of the natural gas compressor. The bolts 13 are rotated into the threaded holes on the surface of the natural gas compressor to install the device. The other is to put the hook 10 on the reserved column. The hook 10 supports the installation of the device by cooperating with the rope 11 and the fixing plate 12. When the device starts working, the pump 21 is started. The pump 21 absorbs the lubricating oil inside the vertical cylinder 1 through the first hose 23. The lubricating oil inside the vertical cylinder 1 is between the vertical pipe 16 and the inner wall of the vertical cylinder 1. There is only the cylinder 14 inside the vertical pipe 16 and no lubricating oil. The pump 21 transports the lubricating oil to the inside of the second hose 24. The second hose 24 is connected to the feed pipe 28 through the third flange 30, the fourth flange 32 and the second threaded rod 33. The solenoid valve 29 on the feed pipe 28 is opened. The lubricating oil enters the feed pipe 28 through the second hose 24, and enters the adjusting pipe 4, the telescopic pipe 3 and the fixed cylinder 2, and finally falls above the piston 15. Then the solenoid valve 29 is closed, the second threaded rod 33 is removed from the third flange 30 and the fourth flange 32, and the second hose 24 is moved away from the feed pipe 28. When the length of the device needs to be adjusted, the electric telescopic rod 25 is started. The electric telescopic rod 25 The curved plate 26 is driven to move upward, and the curved plate 26 drives the regulating tube 4 to move upward through the handle 20, and the regulating tube 4 drives the telescopic tube 3 to stretch, which can not only expand the storage upper limit of the device for the lubricating oil, but also facilitate the extension of the length of the device, thereby facilitating the lubrication of the natural gas compressor. After that, the cylinder 14 is started, and the cylinder 14 drives the piston 15 to move upward, and the piston 15 drives the lubricating oil to move upward. In the process of the lubricating oil moving upward, part of the lubricating oil will enter the transparent frame 7. The operator can observe the quality of the lubricating oil through the transparent frame 7. The filter disc 19 filters the lubricating oil. When the lubricating oil needs to be diverted, the sealing plug 8 is removed from the top of the regulating tube 4 in advance, and a diverter pipe is installed on the top of the regulating tube 4 to transfer it to various places in the natural gas compressor where lubricating oil needs to be added. The diverter pipe is a prior art, and its working principle is common knowledge and is known to those skilled in the art. The device itself can be disassembled. If it is necessary to replenish the lubricating oil in the vertical cylinder 1, rotate the first threaded rod 18 and remove the first threaded rod 18 from the first flange 5 and the second flange 6, so that the device can be disassembled into two parts, upper and lower parts, and the lubricating oil is poured into the vertical cylinder 1. Since a first sealing ring 27 is provided at the top of the vertical tube 16, the lubricating oil in the vertical cylinder 1 will not enter the interior of the vertical tube 16. If the electric telescopic rod 25 is not needed to operate during the extension and retraction of the telescopic tube 3, first move the adjusting tube 4 upward, and the adjusting tube 4 drives the handle 20 to move upward, the arc plate 26 moves away from the handle 20, and rotate the electric telescopic rod 25. The electric telescopic rod 25 rotates inside the U-shaped block 35 through the swing block 34, so that the arc plate 26 can be moved out of the handle 20.
