Finally, the worker opens the equipment door 15 and connects the output pipe of the oil-gas mixer 9 to the outside of the equipment that needs lubrication. The worker then opens the operating door 16 and pours the lubricating oil into the oil tank 12 through the oil filling pipe 14. At this time, the worker operates the control switch group 11 to operate the motor 8. The output shaft of the motor 8 drives the gear pump 4 to operate through the gear pump shaft. At this time, the gear pump 4 absorbs the lubricating oil inside the oil tank 12 through the delivery pipe 1, and discharges it into the oil-gas mixer 9 through the delivery pipe 2. At the same time, the worker operates the air compressor 10 by operating the control switch group 11. The air compressor 10 compresses the gas inside its own cylinder, and the compressed gas is discharged into the oil-gas mixer 9 through the delivery pipe 3. At the same time, the worker operates the oil-gas mixer 9 by operating the control switch group 11.

[0027] Shock absorber bracket 2: It includes a bracket 21, a pipe groove 22, a sliding column 23 and a contact plate 24. The brackets 21 are respectively arranged on the top wall of the shell 1. The lower end of the bracket 21 is provided with a pipe groove 22. The arc surface of the pipe groove 22 is provided with evenly distributed sliding holes.

The contact plate 24 is located inside the pipe groove 22. The shock absorber bracket 2 also includes a support ring 25, a spring 26 and a gas damper 27. The interior of the frame 21 is provided with a support ring 25, and the support ring 25 coincides with the central axis of the adjacent pipeline groove 22. A spring 26 is provided between the slide column 23 and the inner wall of the adjacent support ring 25. The interior of the support ring 25 is installed with evenly distributed gas dampers 27. The springs 26 are sleeved on the outer arc surface of the adjacent gas damper 27. The rear end of the slide column 23 is evenly fixedly connected to the damping telescopic end of the adjacent gas damper 27. When the gear pump oil and gas lubrication station is working, if the delivery pipeline is The second and third conveying pipes shake, which first acts on the contact plate 24. As the conveying pipe shakes in the direction and force, the adjacent contact plates 24 are squeezed. The contact plates 24 slide inside the sliding holes on the arc surface of the pipe groove 22 through the sliding column 23. At the same time, the friction between the sliding column 23 and the sliding hole initially buffers the movement speed of the sliding column 23. The sliding column 23 continuously pulls and squeezes the adjacent spring 26. After the sliding column 23 contacts the gas damper 27, the gas damper 27 can effectively absorb the kinetic energy of the sliding column 23. At this time, the spring 26 will be pulled and squeezed under the force of the sliding column 23. In this process, the elastic force of the spring 26 will gradually increase with the increase in deformation. Under the elastic potential energy of the spring 26, the movement speed of the sliding column 23 and the contact plate 24 can be effectively slowed down, thereby reducing the shaking of the conveying pipe inside the shock-absorbing bracket 2. This reduces the incidence of safety accidents such as loosening of the pipeline connection parts and sealing failure caused by the vibration of the pipeline, which in turn causes oil and gas leakage.

[0028] The working principle of the gear pump oil and gas lubrication station provided by the present utility model is as follows: first, a worker takes a delivery pipe 1, connects one end of the pipe to the oil pipe 13 on the front side wall of the oil tank 12, then passes the other end of the pipe through the leftmost shock-absorbing bracket 2, and then connects it to the oil inlet of the gear pump 4. At this time, the outer arc surface of a part of the delivery pipe 1 inside the shock-absorbing bracket 2 contacts the contact plate 24. Then the worker takes another delivery pipe 2, connects one end of this pipe to the oil outlet of the gear pump 4, then passes the other end of this pipe through the middle shock-absorbing bracket 2, and then connects it to the oil inlet pipe of the oil-gas mixer 9. At this time, the outer arc surface of a part of the delivery pipe 2 inside the shock-absorbing bracket 2 contacts the contact plate 24. Then the worker takes delivery pipe 3 and connects One end of the delivery pipe three is connected to the outlet pipe of the air compressor 10, and then the other end of the delivery pipe three is passed through the shock absorber bracket 2 on the far right, and then connected to the air inlet pipe of the oil-gas mixer 9. At this time, the outer arc surface of the delivery pipe three inside the shock absorber bracket 2 contacts the contact plate 24. Finally, the worker opens the equipment door 15, connects the output pipe of the oil-gas mixer 9 to the external lubrication pipe of the equipment that needs lubrication, and then opens the operating door 16 to pour the lubricating oil into the oil tank 12 through the oil replenishing pipe 14. At this time, the worker operates the control switch group 11 to operate the motor 8, and the output shaft of the motor 8 drives the gear pump 4 to operate through the gear pump shaft. At this time, the gear pump 4 absorbs the lubricating oil inside the oil tank 12 through the delivery pipe one, and discharges it into the oil tank through the delivery pipe two. Enter the interior of the oil-gas mixer 9. At the same time, the worker operates the control switch group 11 to operate the air compressor 10. The air compressor 10 compresses the gas inside its own cylinder, and the compressed gas is discharged through the delivery pipe three into the interior of the oil-gas mixer 9. At the same time, the worker operates the control switch group 11 to operate the oil-gas mixer 9. The oil-gas mixer 9 fully mixes the internal lubricating oil and compressed gas to form a uniform oil-gas mixture, which is discharged through the output pipe to the lubrication pipe of the equipment that needs lubrication. When the gear pump oil-gas lubrication station is working, the gear pump 4, oil-gas mixer 9 and air compressor 10 inside it will vibrate during their operation. At this time, the shock-absorbing pads inside the shock-absorbing groove 5 corresponding to the gear pump 4, oil-gas mixer 9 and air compressor 10 6 absorbs and isolates the vibration generated during the operation of the equipment, reduces the transmission of vibration to the foundation and surrounding components, and avoids the mutual influence between the gear pump 4, the oil-gas mixer 9 and the air compressor 10 due to vibration. At the same time, if the delivery pipeline 1, the delivery pipeline 2 and the delivery pipeline 3 shake, it will first act on the contact plate 24, and squeeze the adjacent contact plates 24 with the shaking direction and force of the delivery pipeline. The contact plate 24 slides inside the sliding hole on the arc surface of the pipeline groove 22 through the sliding column 23. At the same time, the friction between the sliding column 23 and the sliding hole preliminarily buffers the movement speed of the sliding column 23. The sliding column 23 continuously pulls and squeezes the adjacent spring 26. After the sliding column 23 contacts the gas damper 27, the gas damper 27 can effectively absorb the kinetic energy of the sliding column 23.At this time, the spring 26 will be pulled and squeezed by the force of the sliding column 23. During this process, the elastic force of the spring 26 will gradually increase with the increase in deformation. Under the elastic potential energy of the spring 26, the movement speed of the sliding column 23 and the contact plate 24 can be effectively slowed down, thereby reducing the shaking of the conveying pipeline inside the shock-absorbing bracket 2. This reduces the incidence of safety accidents such as loosening of pipeline connections and sealing failure caused by pipeline vibration, which in turn reduces the risk of oil and gas leakage.

[0029] It is worth noting that the motor 8 disclosed in the above embodiment can be of model YE3-132M, the oil-gas mixer 9 can be of model REBS SP-VK, and the air compressor 10 can be a piston air compressor. The control switch group 11 is provided with control buttons corresponding to the motor 8, the oil-gas mixer 9 and the air compressor 10 and used to control their switches.
