Description

Technical Field

[0001] This utility model relates to the field of oil suction pipe technology, and more specifically, to a variable oil suction pipe for gearbox inlet position. Background Technology

[0002] In industrial transmission systems, gearboxes are the core components for transmitting power and changing speed. Their normal operation is highly dependent on good lubrication conditions. The cleanliness of the lubricating oil and the stability of the oil supply directly affect the wear, operating noise and service life of the gearbox. The oil tank in the oil station serves as a storage device for the lubricating oil in the gearbox, while the oil suction pipe is a key component for the oil pump to obtain the lubricating oil.

[0003] Traditional oil suction pipes have a fixed inlet position, making it impossible to adjust the suction height according to the contamination distribution of the lubricating oil in the tank. In actual use, metal shavings, impurities, and oxidized sludge easily accumulate at the bottom of the tank, resulting in excessive impurities in the lubricating oil sucked in by the oil pump. This leads to accelerated wear of gears and bearings inside the gearbox, increasing maintenance costs. As the lubricating oil in the tank is consumed, the oil level drops, and the fixed-position oil suction pipe may suck in foam near the oil surface, causing oil pump cavitation, affecting the stability of oil supply and the life of the oil pump. Therefore, a variable-position oil suction pipe for the gearbox is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a variable oil suction pipe for the gearbox inlet position to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a variable oil suction pipe for the gearbox inlet, including a fixed pipe, one end of which is connected to a connector, and one end of which is connected to a connecting ring. The connector allows for pipe reversal to adapt to the spatial layout within the oil tank. A rotating ring groove is provided in the middle of the connecting ring, and a rotating retaining ring is fixedly connected to the outside of one end of the connector. Multiple sealing rings are embedded around the rotating retaining ring. Through the cooperation of the rotating retaining ring and the rotating ring groove, the connecting ring and the connector can be rotatably connected. The sealing rings allow for rotatable connection without affecting the sealing effect. One end of the connecting ring is connected to a metal tube head, which facilitates the connection of a connecting hose to the connecting ring.

[0006] One end of the metal tube head is connected to a connecting hose. The connecting hose is flexible and provides room for adjustment of the oil suction port position. One end of the connecting hose is fixedly connected to a balance box. A suction port is opened on the side of the connecting hose near the balance box, which facilitates the extraction of liquid. A counterweight and an air bladder are set in the middle of the balance box. An inlet pipe is connected to the side of the balance box. Gas is injected into the air bladder through the inlet pipe. By cooperating with the weight of the counterweight, the buoyancy of the balance box can be changed, thereby adjusting the height of the flow area and realizing the adjustment of the oil suction position.

[0007] A connecting screw ring is fixedly connected to one side of the connecting ring, and a fastening bolt is inserted into one side of the metal tube head. The connecting ring and the metal tube head are connected by the connecting screw ring, and the connecting screw ring is squeezed by the fastening bolt, which can improve the stability of the connection and prevent loosening.

[0008] Preferably, a valve is connected to the end of the fixed pipe away from the connector, a liquid pump is connected to one side of the valve, the connecting ring is located on one side of the connector, the metal pipe head is perpendicular to the fixed pipe, and the valve is connected to the liquid pump to control the extraction and disconnection of lubricating oil. At the same time, the metal pipe head is perpendicular to the fixed pipe to realize the turning of the pipeline and adapt to the spatial layout inside the oil tank.

[0009] Preferably, the rotating ring groove is adapted to the rotating retaining ring, the rotating retaining ring is disposed in the middle of the rotating ring groove, and the wall of the sealing ring is in contact with the inner wall of the rotating ring groove. By the interaction of the rotating ring groove and the rotating retaining ring base, a rotating connection can be achieved, which can adjust the orientation angle of the suction port, and the sealing performance of the connection can be improved by the sealing ring.

[0010] Preferably, one end of the connecting screw ring extends into the interior of the metal tube head and is threadedly connected to the inner cavity of the metal tube head. The interior of one end of the connecting screw ring is set with a bevel to facilitate the connection of the connecting screw ring to the metal tube head, thereby realizing the connection between the connecting ring and the connecting hose and facilitating the smooth flow of lubricating oil.

[0011] Preferably, the fastening bolt is threaded to the metal pipe head, one end of the fastening bolt is in contact with the wall of the connecting ring, and the diameter of the connecting ring, the connecting head, and the metal pipe head is the same as the diameter of the connecting hose. By rotating the fastening bolt, the connecting ring is squeezed to improve the connection strength and prevent loosening.

[0012] Preferably, the inner cavity of the fixed tube is connected to the inner cavity of the connecting hose through a connector, a connecting ring, and a metal tube head. The inner cavity of the inlet tube is connected to the inner cavity of the airbag. A valve core is provided in the middle of the inlet tube, which can form a complete lubricating oil extraction channel, ensuring that the lubricating oil sucked in by the suction port can smoothly enter the liquid pump through the pipeline and then be delivered to the gearbox, ensuring smooth oil flow and reducing pressure loss.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model firstly utilizes the cooperation between the counterweight and the air bladder in the balance box to flexibly adjust the depth of the suction inlet according to the level and contamination of the lubricating oil in the oil tank. When there are many impurities at the bottom of the oil tank, the air bladder is inflated to increase buoyancy and move the suction inlet upward; when the liquid level drops, the air is deflated to reduce buoyancy and move the suction inlet downward, ensuring that clean lubricating oil is always drawn in, which can improve the oil suction effect and facilitate adjustment and use.

[0015] 2. This utility model also features a connecting hose that is rotatably connected to a connecting ring and a connector via a metal tube head. This allows for adjustment of the orientation of the suction inlet at one end of the connecting hose. A sealing ring can seal the rotatable connection. The connecting ring is threaded to the metal tube head for easy connection and use. Furthermore, by rotating the fastening bolt to compress the connecting ring, the connection strength between the metal tube head and the connecting ring can be improved, preventing loosening and enhancing the performance.

[0016] In summary, through the interaction of the above-mentioned multiple functions, the depth of the suction port can be flexibly adjusted according to the level and contamination of the lubricating oil in the oil tank, so that the suction port always draws in clean lubricating oil, which can improve the oil suction effect and facilitate adjustment and use.

The sealing rings 16 can achieve rotatable connection without affecting the sealing effect. A metal tube head 11 is connected to one end of the connecting ring 4. The metal tube head 11 facilitates the connection of the connecting hose 5 to the connecting ring 4.

[0024] One end of the metal tube head 11 is connected to a connecting hose 5. The connecting hose 5 is flexible, providing room for adjustment of the oil suction port position. One end of the connecting hose 5 is fixedly connected to a balance box 7. A suction port 6 is opened on the side of the connecting hose 5 near the balance box 7, which facilitates the extraction of liquid. A counterweight 8 and an air bladder 9 are set in the middle of the balance box 7. An inlet pipe 10 is connected to the side of the balance box 7. Gas is injected into the air bladder 9 through the inlet pipe 10. The buoyancy of the balance box 7 can be changed by cooperating with the weight of the counterweight 8, thereby adjusting the height of the flow area and realizing the adjustment of the oil suction position.

[0025] A connecting screw ring 13 is fixedly connected to one side of the connecting ring 4, and a fastening bolt 12 is inserted into one side of the metal tube head 11. The connecting ring 4 and the metal tube head 11 are connected by the connecting screw ring 13, and the connecting screw ring 13 is squeezed by the fastening bolt 12, which can improve the stability of the connection and prevent loosening.

[0026] As attached Figure 1-4As shown, a valve 2 is connected to the end of the fixed pipe 1 away from the connector 3. A liquid pump is connected to one side of the valve 2. A connecting ring 4 is located on one side of the connector 3. The metal pipe head 11 is perpendicular to the fixed pipe 1. The rotating ring groove 15 is adapted to the rotating retaining ring 14. The rotating retaining ring 14 is located in the middle of the rotating ring groove 15. The wall of the sealing ring 16 is in contact with the inner wall of the rotating ring groove 15. One end of the connecting screw ring 13 extends into the interior of the metal pipe head 11 and is threadedly connected to the inner cavity of the metal pipe head 11. The interior of one end of the connecting screw ring 13 is set as a bevel. The fastening bolt 12 is threadedly connected to the metal pipe head 11. One end of the fastening bolt 12 is in contact with the wall of the connecting screw ring 13. The diameters of the connecting ring 4, connector 3, and metal pipe head 11 are the same as the diameter of the connecting hose 5. The inner cavity of the fixed pipe 1 is connected to the inner cavity of the connecting hose 5 through the connector 3, connecting ring 4, and metal pipe head 11.

[0028] Start the liquid pump; suction port 6 begins to draw lubricating oil from the oil tank and automatically feeds it into the connecting position.

[0029] When the oil suction position needs to be adjusted, air is inflated into the airbag 9 through the inlet pipe 10 to increase buoyancy. The balance box 7 drives the connecting hose 5 to float up. The gas in the airbag 9 is released through the valve core to reduce buoyancy. The balance box 7 sinks under the gravity of the counterweight 8, thus achieving position adjustment.
