Description

Technical Field

[0001] The invention relates to the technical field of oil pumping units, in particular to a beam bearing seat for a beam pumping unit. Background Art

[0002] The walking beam pumping unit is a common mechanical oil production equipment. Its structure consists of a base, a reduction gearbox, a crank, a connecting rod, a beam and a sucker rod. The beam is the core structural component of the walking beam and plays an important role in transmitting force and balancing during reciprocating motion. In order to ensure the stability and reliability of the movement between the beam and the frame, bearing seats are usually provided at both ends of the beam to support the swing axis of the beam.

[0003] In the prior art, a Chinese patent document with the announcement number CN113775656B proposes a beam bearing seat for a beam pumping unit, comprising: a base plate; an adjusting screw is also installed on the right side of the support frame through threaded matching; and four fixing bolts are symmetrically embedded and installed on the base plate. Although this technology matches the best bearing position by sliding the bearing support block left and right, it can also transmit a signal alarm through the pressure sensor when the bolt is loose, so as to achieve the purpose of reducing vibration and facilitating inspection, solving the problem that the existing bearing seat is prone to vibration and the fixing bolts are inconvenient to check. However, this technology is consistent with the traditional method in that: in the traditional beam pumping unit, the bearing structure supporting the beam usually adopts a fixed rolling bearing design, and its structure fails to address the beam during the pumping process. The beam dynamically responds to the periodic left and right swings. When the beam swings to one side, the force on the bearing on that side increases significantly, while the load on the bearing on the other side decreases. At this time, the traditional bearing structure cannot automatically adjust the support state according to the load change, which can easily lead to local compression and increased wear of the bearing on the force side. The non-force side produces abnormal noise or uneven wear due to the no-load operation of the rolling element, which in turn causes unstable operation of the beam and shortened service life. In addition, due to the continuous swing of the beam structure itself, the inner and outer rings of the bearing move frequently relative to each other. It is difficult to achieve continuous and uniform lubrication of the rolling contact surface with traditional manual lubrication. The lubricating oil is often unevenly distributed and some areas are insufficiently lubricated, which leads to increased operating resistance of the bearing under high load or uneven load conditions, resulting in dry friction and even burning of the shaft. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a crossbeam bearing seat for a walking beam pumping unit to solve the problem that the existing bearing structure cannot automatically adjust the support state according to load changes, which easily leads to local compression and increased wear of the bearing on the load side, as well as the lack of continuous and uniform lubrication of the rolling contact surface.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a bearing assembly and a lubrication assembly, by setting bearing assemblies that adapt to the left and right swing characteristics of the connecting shaft at both ends, the ball and the first spring sheet are used to cooperate to realize automatic adjustment of the load state and reduce friction. At the same time, combined with the lubrication assembly that can automatically distribute lubricating oil as the crossbeam moves, the bearing's load-bearing capacity and operating stability are effectively improved, the wear and maintenance frequency caused by uneven lubrication are reduced, and the working reliability and service life of the whole machine are significantly improved.

[0016] By setting up a bearing assembly and utilizing the load distribution changes formed during the left and right swinging of the beam, combined with the cooperation of the ball and the first spring leaf, a coordinated improvement of dynamic load-bearing and friction reduction functions is achieved. When the beam is biased to one side due to force, the load-bearing capacity of this side increases, and the ball is compressed inwardly under the action of the first spring leaf, and double contact is made through the rotating shaft itself and the ball and the U-shaped groove inside the fixing ring, which significantly increases the contact area, thereby improving the load-bearing capacity of this side. On the contrary, when the load on the other side decreases, the first spring leaf rebounds and pushes the ball to re-contact the U-shaped groove, utilizing the rolling characteristics of the ball to reduce friction resistance and improve the swinging flexibility of the beam. This structure not only improves the dynamic response capability of the load-bearing, but also has a significant effect in reducing friction and extending service life.

[0017] By setting up an intermittent component and a lubrication component, the two work together to intermittently cause the lubricating oil inside the oil storage cylinder to automatically drip out to the contact point between the fixed ring and the rotating shaft as the beam swings, so that the lubricating oil is evenly distributed to the bearing contact area during operation, avoiding dry friction caused by untimely or uneven manual refueling. This structure simplifies the maintenance process, improves lubrication efficiency, effectively reduces bearing wear, extends service life, and improves the stability and reliability of the entire machine operation.

[0018] By setting an intermittent component, when the beam swings, the lifting column is prompted to move upward with the ratchet. At this time, the ratchet will push the tooth groove on one side of the ratchet and rotate one tooth groove position. At this time, by setting multiple tooth grooves on the outside of the ratchet, the ratchet is prompted to rotate continuously. At the same time, by setting a toggle bolt on one side of the ratchet, when the multiple tooth grooves are continuously rotated by the push of the ratchet, the toggle bolt is prompted to contact the bottom of the alignment column, and then the lubrication component is prompted to transport oil to the bearing. Through the ratchet, the time when the toggle bolt contacts the alignment column is extended, thereby achieving the effect of intermittent oil supply and lubrication by relying on the natural swing of the beam without the need for electric control, thereby improving lubrication efficiency and reducing oil consumption.

[0019] By setting up a cleaning component and arranging an S-shaped plate scraper at the shaft position, the relative movement generated by the swing of the beam is used to remove dust and oil stains attached to the inner surface of the fixed ring. During operation, the S-shaped plate cooperates with the shaft groove to brush and clean the inside of the U-shaped groove during rotation to prevent the accumulation of oil and dirt, and to prevent the accumulation of foreign matter that affects the rotation flexibility and lubrication effect. At the same time, the scraped impurities will flow from the inside of the leak hole into the multi-layer filter structure, which will prompt the filtered impurities to automatically slide into the collection box, realizing the self-purification function of the lubrication system. At the same time, the filtered lubricating oil is recovered by setting an oil collection box, which effectively prevents waste of resources and improves the environmental protection of the device. The design has a simple structure and self-cleans during operation, reduces the frequency of manual cleaning, helps maintain the normal operation of bearings and surrounding components, and improves equipment stability.

[0020] By setting up a warning component, when the lubricating oil inside the oil storage cylinder decreases, the counterweight plate will drop accordingly. At this time, the traction rope drives the baffle to drop and drives the flagpole to retract into the inside of the storage cylinder, thereby reminding that the lubricating oil residue is insufficient, realizing the warning function, and then facilitating timely refueling of the inside of the oil storage cylinder.

[0025] The following describes in detail a beam bearing seat for a beam pumping unit provided by the present invention, with reference to the accompanying drawings and specific embodiments. It is also noted that, for the sake of completeness, the following embodiments are optimal and preferred embodiments, and those skilled in the art may employ alternative implementations for known technologies. Furthermore, the accompanying drawings are intended only to provide a more detailed description of the embodiments and are not intended to limit the present invention.

[0026] like Figures 1 to 13As shown, an embodiment of the present invention provides a beam bearing seat for a walking beam pumping unit, comprising a beam 46 and a base 47. The bottom of the middle portion of the beam 46 is mounted on the top of the base 47. The bottom of the beam 46 is fixedly connected to a connecting shaft 1. The top of the base 47 is fixedly connected to two symmetrically arranged fixing seats 2. The top of the fixing seat 2 is provided with a bearing assembly for supporting the beam 46 to swing left and right, and providing a bearing capacity increase on the corresponding side and friction reduction compensation on the other side when the beam 46 deviates to one side due to force eccentricity. The bearing assembly comprises a fixing ring 3 fixedly connected to the top of the fixing seat 2. The interior of the fixing ring 3 is rotatably clamped with a rotating shaft 4. The interiors of the two rotating shafts 4 are respectively fixedly connected to the exteriors of the two ends of the connecting shaft 1. A U-shaped groove 5 is provided inside the fixing ring 3. The exterior of the rotating shaft 4 is in an oblate shape, and the rotating shaft 4 is in an oblate shape. The outside of the shaft 4 is annularly and equidistantly provided with a plurality of grooves 9, the outside of the rotating shaft 4 is engaged with the inside of the U-shaped groove 5, and sealing grooves 7 are respectively provided on both sides of the fixing ring 3. When the rotating shaft 4 is installed inside the fixing ring 3, one side of the sealing gasket 8 contacts one side of the rotating shaft 4, and one side of the outside of the sealing gasket 8 is engaged with the inside of the sealing groove 7. A lubrication component is provided on the top of the fixing ring 3, and the lubrication component is used to automatically and intermittently lubricate the bearing assembly. An intermittent component is provided on one side of the lubrication component, and the intermittent component is used in conjunction with the lubrication component to perform intermittent automatic lubrication on the bearing assembly. A cleaning component is provided inside the fixing ring 3, and the cleaning component is used to clean the inside of the bearing assembly and collect excess lubricating oil. A warning component is provided on one side of the fixing seat 2, which provides an oil amount warning in conjunction with the state change of the lubrication component; By setting up bearing assemblies and lubrication assemblies, bearing assemblies that adapt to the left and right swing characteristics of the connecting shaft 1 are set at both ends of the connecting shaft 1, and the ball 11 and the first spring piece 12 are used to cooperate to realize automatic adjustment of the load state and reduce friction. At the same time, combined with the lubrication assembly that can automatically distribute lubricating oil as the crossbeam 46 moves, the bearing's load-bearing capacity and operating stability are effectively improved, the wear and maintenance frequency caused by uneven lubrication are reduced, and the working reliability and service life of the whole machine are significantly improved.

[0027] like Figures 1 to 6 As shown, the outer portion of the rotating shaft 4 is provided with a plurality of slots 33 equidistantly in an annular shape. The plurality of slots 33 are located between pairs of the plurality of grooves 9. The first spring piece 12 is fixedly connected to the interior of the slot 33. The ball 11 is rotatably engaged with the interior of the slot 33. One side of the ball 11 contacts one side of the first spring piece 12. When the rotating shaft 4 is installed inside the fixing ring 3, one side of the ball 11 contacts the inner wall of the U-shaped groove 5. By setting the bearing assembly, utilizing the load distribution change formed by the crossbeam 46 during the left and right swinging process, combined with the cooperation of the ball 11 and the first spring piece 12, the coordinated improvement of dynamic load-bearing and friction reduction functions is achieved. During operation, the crossbeam 46 will drive the connecting shaft 1 to swing and rotate left and right, and at the same time, the connecting shaft 1 will swing the rotating shaft 4 left and right. When the crossbeam 46 is biased to one side due to the force, the bearing capacity of this side increases. At this time, the ball 11 is compressed inwardly under the action of the first spring piece 12, and double contact is made with the U-shaped groove 5 inside the fixing ring 3 through the rotating shaft 4 itself and the ball 11, which significantly increases the contact area, thereby improving the bearing capacity of this side. On the contrary, When the load on the other side decreases, the first spring sheet 12 rebounds and pushes the ball 11 to re-contact the U-shaped groove 5, and uses the rolling characteristics of the ball 11 to reduce friction resistance, thereby improving the swing flexibility of the beam 46. This structure not only improves the dynamic response capability of the load, but also has a significant effect in reducing friction and extending life. At the same time, by setting the shape of 4 to be oblate, the oblate structure can limit the rotation of the shaft 4 in a certain direction, so that it has higher stability in a specific direction, which helps to accurately guide the left and right swing direction of the beam 46 to prevent deflection, and at the same time adapts to the U-shaped groove 5, so that it is stably stuck inside the U-shaped groove 5, thereby increasing the stability of the shaft 4.

[0028] like Figures 1 to 13 As shown, the lubrication assembly includes an oil storage cylinder 14 installed on the top of the fixing ring 3, one side of the oil storage cylinder 14 is fixedly connected to the fixing box 13, the bottom of the fixing box 13 is fixedly connected to one side of the fixing seat 2, the bottom of the oil storage cylinder 14 is connected to the connecting cylinder 20, the top of the connecting cylinder 20 is fixedly connected to the second trapezoidal block 23, the top of the second trapezoidal block 23 is provided with a first trapezoidal column 21, the top of the first trapezoidal column 21 is fixedly connected to a counterweight plate 22, the size of the counterweight plate 22 is the same as that of the first trapezoidal column The top of the first trapezoidal column 21 and the top of the connecting cylinder 20 are adapted to the specifications and dimensions. The shape of the first trapezoidal column 21 is an inverted trapezoid. When the first trapezoidal column 21 and the counterweight plate 22 stay inside the connecting cylinder 20, the top of the first trapezoidal column 21 is located at the connection between the connecting cylinder 20 and the oil storage cylinder 14. The bottom of the second trapezoidal block 23 is fixedly connected to the guide cylinder 24. The bottom of the first trapezoidal column 21 is fixedly connected to the alignment column 29. The bottom of the alignment column 29 passes through the interior of the second trapezoidal block 23 and the guide cylinder 24. By setting up an intermittent component and a lubricating component, the two cooperate with each other, and can intermittently cause the lubricating oil inside the oil storage cylinder 14 to automatically drip out to the contact point between the fixed ring 3 and the rotating shaft 4 as the crossbeam 46 swings, so that the lubricating oil is evenly distributed to the bearing contact area during operation, avoiding dry friction caused by untimely or uneven manual refueling. When the rotating shaft 4 swings left and right, the intermittent component is triggered, causing the alignment column 29 to move upward with the first trapezoidal column 21 and the counterweight plate 22. At this time, by setting the shape of the first trapezoidal column 21 to be an inverted trapezoid and the specifications and dimensions of the counterweight plate 22 to be compatible with the specifications and dimensions of the internal space of the connecting cylinder 20, when the first trapezoidal column 21 moves upward, the diameter of the bottom of the first trapezoidal column 21 is smaller than that of the first trapezoidal column 21. 21 top diameter, at this time there will be a gap between the first trapezoidal column 21 and the connection between the connecting cylinder 20 and the oil storage cylinder 14, which will cause the lubricating oil inside the oil storage cylinder 14 to flow out, thereby achieving the effect of automatically releasing the lubricating oil. This structure simplifies the maintenance process, improves the lubrication efficiency, effectively reduces bearing wear, extends the service life, and improves the stability and reliability of the whole machine operation. At the same time, when the toggle bolt 59 in the intermittent component is away from the bottom of the alignment column 29, the alignment column 29 automatically drops due to the gravity of the counterweight plate 22, causing the gap between the first trapezoidal column 21 and the bottom of the oil storage cylinder 14 to be blocked, thereby preventing the lubricating oil from flowing out. Through this design combined with the intermittent component, the effect of intermittent output of lubricating oil is achieved, which enables the lubricating oil to be used for a long time.

[0029] like Figure 8 and Figure 9 As shown, the outside of the top of the connecting cylinder 20 is fixedly connected with an annular box 25, and the top and bottom of the side where the annular box 25 and the connecting cylinder 20 are connected are respectively provided with an oil inlet hole 26 and an oil outlet hole 27.

One side of the bottom of the connecting cylinder 20 is connected with an oil delivery pipe 61, and the input end of the oil delivery pipe 61 is connected to one side of the bottom of the collecting box 60, and the output end of the oil delivery pipe 61 passes through the top of the fixing ring 3 and is connected to the inside of the fixing ring 3. The bottom of the inside of the annular box 25 is fixedly connected with a sloped ring 28, and the sloped side of the sloped ring 28 is located on one side of the oil outlet hole 27. The bottom end of the alignment column 29 is arc-shaped. Through the provided annular box 25 and the second trapezoidal block 23, when the lubricating oil flows out from the gap between the first trapezoidal column 21 and the bottom of the oil storage cylinder 14, the lubricating oil will flow into the oil inlet hole 26 along the slope of the outside of the second trapezoidal block 23. At this time, the provided sloped ring 28 can prevent the lubricating oil from remaining inside the annular box 25, and promote the lubricating oil to flow into the oil outlet hole 27 along the slope of one side of the sloped ring 28. At this time, through the provided collecting box 60 and the oil pipe 61, when the lubricating oil flows out from the oil outlet hole 27, it will flow into the inside of the collecting box 60 and the inside of the oil pipe 61, and then enter the inside of the fixed ring 3, thereby promoting the lubrication effect of the inside of the fixed ring 3 and the outside of the rotating shaft 4, avoiding the problem of uneven lubrication in traditional ways.

At this time, by setting the shape of the ratchet 50 to be arc-shaped and the length of one end of the ratchet 50 extending from the inside of the positioning groove 52 to be longer than the other end of the ratchet 50, the center of gravity of the ratchet 50 is at the top. At this time, the ratchet 50 will rotate one tooth groove position against the tooth groove on one side of the ratchet 58. At this time, by setting a plurality of tooth grooves on the outside of the ratchet 58, the ratchet 58 is prompted to rotate continuously. At the same time, by setting a toggle bolt 59 on one side of the ratchet 58, the multiple tooth grooves are pushed by the ratchet 50. During continuous rotation, the toggle bolt 59 is prompted to contact the bottom of the alignment column 29, thereby prompting the lubrication component to deliver oil to the bearing. The ratchet 58 is provided to extend the time for the toggle bolt 59 to contact the alignment column 29, thereby achieving the effect of intermittent oil supply and lubrication by relying on the natural swing of the crossbeam 46 without the need for electric control, thereby improving lubrication efficiency and reducing oil consumption. At the same time, through the provided positioning cylinder 55 and the latch 57, when the ratchet 50 rotates against the ratchet 58, the latch 57 will move upward to prompt the extrusion spring 56 to contract. When the ratchet 58 rotates past a tooth groove position, the latch 57 automatically rebounds and is stuck in the next tooth groove through the action of the extrusion spring 56, thereby playing the role of limiting the ratchet 58 to prevent the ratchet 58 has the problem of self-rotation in the absence of power. At the same time, because a plurality of grooves 9 are provided on the outside of the rotating shaft 4, when the outside of the rotating shaft 4 is away from the bottom of the connecting bolt 62 and the groove 9 moves to the bottom of the connecting bolt 62, the rebound spring 54 starts to rebound to prompt the lifting column 49 to move downward, and at the same time, the ratchet 50 moves downward. At this time, through the provided alignment groove 52 and the second spring piece 51, when the ratchet 50 moves downward, the bottom of the ratchet 50 will contact the outside of the ratchet 58. At this time, the top of the ratchet 50 will shrink toward the inside of the alignment groove 52, and at the same time squeeze the second spring piece 51 to shrink. After that, when the top of the ratchet 50 moves to the initial position, that is, the top of the ratchet 50 moves to the tooth groove on one side of the ratchet 58 When the first trapezoidal column 21 is lifted, the second spring sheet 51 automatically rebounds, causing the top of the ratchet 50 to contact the inside of the tooth groove on one side of the ratchet 58 again, thereby facilitating the next use. At the same time, it should be noted that the groove shape of the groove 9 and the number of S-shaped plates 10 can be changed according to actual conditions. The larger the groove shape of the groove 9 and the fewer the number of S-shaped plates 10, the longer the interval time, thereby achieving a longer-term use effect. At the same time, the weight of the counterweight plate 22 can also be changed. The heavier the counterweight plate 22, the shorter the distance that the alignment column 29 carries the first trapezoidal column 21 to rise, which makes the gap between the first trapezoidal column 21 and the bottom of the oil storage cylinder 14 smaller, so that the effect of drip-type lubrication can be achieved, and the lubricating oil can be used for a long time.

[0031] like Figures 4 to 10As shown, the cleaning assembly includes a plurality of S-shaped plates 10 fixedly connected to the interior of the groove 9. The end of the S-shaped plate 10 away from the groove 9 is arc-shaped, and the arc-shaped end of the S-shaped plate 10 contacts the interior of the U-shaped groove 5. The bottom of the interior of the fixing ring 3 is provided with a plurality of leakage holes 6. The diameter of the leakage hole 6 is smaller than the diameter of the ball 11. By setting a cleaning component, by setting an S-shaped plate 10 scraper at the position of the shaft 4, the dust and oil attached to the inner surface of the fixed ring 3 are removed by the relative movement generated by the swing of the crossbeam 46. During operation, the shaft 4 will carry the S-shaped plate 10 to swing left and right. At this time, the S-shaped plate 10 will cooperate with the groove 9 of the shaft 4, and can brush and clean the inside of the U-shaped groove 5 during rotation to prevent the accumulation of oil and dirt, and prevent the accumulation of foreign matter that affects the rotation flexibility and lubrication effect. At the same time, the scraped impurities will flow into the multi-layer filter structure from the inside of the leak hole 6. By setting the S-shaped plate 10 to be S-shaped, since the crossbeam 46 swings left and right, when it moves to the side load On one side, the S-shaped shape disperses the bearing force. On the one hand, this structure can absorb the eccentric load impact generated when the beam 46 swings. On the other hand, the S-shaped plate 10 can generate a swinging trajectory covering the left and right sides under the drive of the beam 46, thereby expanding the cleaning area and effectively avoiding the cleaning blind spot problem caused by the fixed or straight cleaning structure. At the same time, the size of the leakage hole 6 is set to avoid the problem of the ball 11 being stuck in the leakage hole 6. At the same time, it should be noted that due to the provision of multiple balls 11, lubricating oil and impurities are allowed to flow in the gaps between the multiple balls 11, thereby prompting excess oil stains to flow into the leakage hole 6.

[0032] like Figure 1 and Figure 10 As shown, the bottom of the fixed base 2 is fixedly connected to the inside of the filter box 30, the top of the filter box 30 is communicated with the bottom of the leak hole 6, the inside of the filter box 30 is fixedly connected to the first filter plate 31 at an inclined angle, one side of the filter box 30 is fixedly connected to the alignment box 36, the top of the first filter plate 31 is fixedly connected to a plurality of second filter plates 32 at an angle inclined toward the alignment box 36, one side of the filter box 30 is fixedly connected to a guide plate 35 inclined toward one side of the alignment box 36, the guide plate 35 is located at the bottom of the first filter plate 31, and the bottom of the alignment box 36 is slidably connected to a sundry box 37, and the top opening of the sundry box 37 is located at the bottom of the output end of the guide plate 35; By setting the second filter plate 32 and the first filter plate 31, when excess lubricating oil and oil stains flow into the top of the first filter plate 31 through the leakage hole 6, by setting the inclination angle of the first filter plate 31, the oil stains flow along the top of the first filter plate 31 and are filtered at the top of the first filter plate 31. At the same time, the excess oil stains will pass through multiple second filter plates 32 for secondary filtration. At this time, by setting the second filter plate 32 to be inclined toward the side of the alignment box 36, the filtered impurities are automatically slid into the collection box 37 along the guide plate 35, realizing the self-purification function of the lubrication system. At the same time, the filtered lubricating oil will pass through the interior of the first filter plate 31. By setting the oil collection box 34, the filtered oil is recovered, effectively preventing resource waste and improving the environmental protection of the device. The design has a simple structure and self-cleaning during operation, reducing the frequency of manual cleaning, helping to maintain the normal operation of bearings and surrounding components and improving equipment stability.

[0033] like Figure 1 and Figure 10 As shown, an oil collecting box 34 is slidably connected to the bottom of the fixing base 2. The oil collecting box 34 is located at the bottom of the first filter plate 31. The first filter plate 31 and the second filter plate 32 are both provided with a plurality of holes. The size of the holes in the second filter plate 32 is larger than the size of the holes in the first filter plate 31. By setting the internal holes of the second filter plate 32 to be larger than the internal holes of the first filter plate 31, when oil stains flow into the top of the first filter plate 31, the first filter plate 31 will intercept small impurities, causing excess lubricating oil to flow into the oil collection box 34. At the same time, large impurities will be intercepted by the second filter plate 32, causing the large impurities to flow into the collection box 37 along the trajectory of the second filter plate 32. This design is more suitable for the use of viscous liquids such as lubricating oil, avoiding the problem of agglomeration or accumulation caused by one-time filtration.

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 11As shown, the warning assembly includes a storage tube 38 mounted on the top of the base 47, one side of the storage tube 38 is fixedly connected to a support frame 45, the bottom end of the support frame 45 is fixedly connected to the top of the base 47, the interior of the storage tube 38 is fixedly connected to a return spring 39, the top of the return spring 39 is fixedly connected to a baffle 41, the top of the baffle 41 is rotatably connected to a flagpole 42, the interior of the top of the oil storage tube 14 is fixedly connected to a connecting plate 18, and the end of the connecting plate 18 away from the oil storage tube 14 is fixedly connected to a protective tube 17. The outside of the bottom end of the protective cylinder 17 is fixedly connected to a retaining ring 48, and the outside of the top of the protective cylinder 17 is slidably connected to the counterweight plate 16. The diameter of the counterweight plate 16 is adapted to the diameter of the inside of the oil storage cylinder 14. The top of the counterweight plate 16 is fixedly connected to a traction rope 40. The end of the traction rope 40 away from the counterweight plate 16 passes through the bottom of the storage cylinder 38 and the inside of the return spring 39 through a plurality of pulleys and is fixedly connected to the bottom of the retaining ring 48. The distance between the bottom of the retaining ring 48 and the counterweight disc 22 is greater than the movement trajectory of the alignment column 29. By means of the warning component, when the lubricating oil inside the oil storage cylinder 14 drops, the counterweight plate 16 will drop accordingly. At this time, the traction rope 40 drives the baffle plate 41 to drop and drives the flag pole 42 to retract into the inside of the storage cylinder 38, thereby achieving a reminder that the lubricating oil is insufficient and realizing a warning function, thereby facilitating timely refueling of the inside of the oil storage cylinder 14. At the same time, by means of the baffle ring 48 and the spacing between the baffle ring 48 and the counterweight plate 22, when the counterweight plate 16 moves to the bottom end of the protective cylinder 17, it will be blocked by the baffle ring 48, thereby avoiding the problem of the counterweight plate 16 being separated from the outside of the protective cylinder 17. It can also avoid the problem that the counterweight plate 16 and the protective tube 17 affect the movement of the counterweight plate 22 and the first trapezoidal column 21. At the same time, through the setting of the flagpole 42, since the oil pump will generate noise when it is running, in order to avoid electronic and sound interference, the flag is easier to observe. It should be noted here that the flag is just a representative. Anything that is conspicuous and can be retracted into the storage tube 38 and the weight does not exceed the force of the counterweight plate 16 and the return spring 39 can be replaced, such as a ball block, etc. At the same time, through the setting of the return spring 39, when it returns later, the baffle 41 will return to its original height with the flagpole 42.

[0035] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 9 and Figure 11As shown, a positioning plate 43 is fixedly connected to one side of the bottom of the flagpole 42, a slide groove 44 is opened on one side of the storage cylinder 38, the outer portion of the positioning plate 43 is slidably connected to the inner portion of the slide groove 44, and one side of the top of the oil storage cylinder 14 is connected to the refueling pipe 15. When the bottom of the positioning plate 43 contacts the top of the storage cylinder 38, the position of the bottom of the counterweight plate 16 is higher than the output end of the refueling pipe 15. A pull rope 19 is slidably connected to the inside of the protective cylinder 17, one end of the pull rope 19 is fixedly connected to the top of the counterweight plate 22, and the other end of the pull rope 19 is bolted to the top of the fixing box 13. The normal state of the pull rope 19 is in a relaxed state. By providing the positioning plate 43 and the slide 44, during normal use, the positioning plate 43 slides inside the slide 44. When the lubricating oil in the oil storage barrel 14 is used up, the flagpole 42 is pulled and rotated to cause the positioning plate 43 to rotate to the top of the storage barrel 38. At this time, the counterweight plate 16 moves upward. At the same time, the position of the counterweight plate 16 is fixed by the positioning of the positioning plate 43. At this time, lubricating oil is added to the inside of the oil storage barrel 14 through the filling pipe 15, thereby facilitating the addition of lubricating oil. At the same time, when the lubricating oil is full, the flagpole 42 is rotated to cause the positioning plate 43 to move to the inside of the slide 44. At this time, the counterweight plate 16 descends and covers The cover is placed on the top of the lubricating oil, making it convenient to use. At the same time, the pull rope 19 is provided, so that the inside of the rotating shaft can be cleaned when the oil pump is not running. After positioning the position of the counterweight plate 16, the pull rope 19 is pulled to cause the counterweight plate 22 to rise with the first trapezoidal column 21. At this time, there is a gap between the first trapezoidal column 21 and the bottom of the oil storage cylinder 14. At this time, water is poured into the interior of the oil storage cylinder 14 through the refueling pipe 15, causing water to flow from the inside of the oil storage cylinder 14 into the inside of the fixing ring 3 and the outside of the rotating shaft 4. At the same time, the sealing gasket 8 is opened to cause impurities inside the rotating shaft 4 and the fixing ring 3 to be flushed out from both sides of the rotating shaft 4, thereby achieving the effect of thorough water cleaning.
