Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment maintenance technology, and specifically relates to an oiling device for mechanical equipment maintenance. Background Technology

[0002] To reduce the wear and tear, natural corrosion, and other damage to mechanical equipment during long-term operation, which can lead to a decline in technical performance, regular maintenance is necessary to extend the service life of the equipment. This requires the use of a lubrication device for mechanical equipment maintenance.

[0003] The invention disclosed in CN221098249U is an oiling device for mechanical equipment maintenance. By installing the main body of the device, the adjustment capability of the device is improved. In actual use, the position and distance of the oiling head can be easily adjusted according to the needs of use, which facilitates oiling operations at different locations and improves the market competitiveness of the oiling device for mechanical equipment maintenance.

[0004] However, the oil injection device provided by the above-mentioned utility model requires an oil pump to transport oil during use. The oil pump results in high oil injection pressure, which makes it difficult to control the amount of oil injected and also poses a safety hazard. At the same time, the oil injection device requires the drive of multiple hydraulic cylinders to move the spray gun, which makes the cost of the oil injection device and its maintenance cost high.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this utility model is to provide an oil injection device for the maintenance of mechanical equipment, which can solve the problems of inconvenient adjustment of the oil injection volume and high cost of the device and maintenance.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A lubrication device for maintaining mechanical equipment includes a support assembly, the support assembly including a mounting plate for mounting the equipment and components, and the lubrication device further includes:

[0009] The oil injection device body includes an oil storage tank for storing and transporting mechanical oil. The oil storage tank is fixedly connected to a mounting plate to support it and ensure stability when the tank moves. A pressure plate is installed inside the oil storage tank, movable up and down. The movement of the pressure plate within the mounting plate compresses the mechanical oil, injecting it into the machinery. Threaded push rods are installed on the top wall of the oil storage tank and the pressure plate, driving the pressure plate to move within the tank and further compress the mechanical oil. An oil delivery pipe is fixedly connected to the inner wall of the top wall of the oil storage tank at the inlet, allowing oil injected through the inlet to flow through the pipe. The pressure plate has a mounting hole at its center, through which it is fitted onto the oil supply pipe. This ensures that the installation of the oil supply pipe does not affect the sliding of the pressure plate within the oil reservoir. Simultaneously, the oil supply pipe ensures that the mechanical oil injected into the oil reservoir is positioned below the pressure plate. An oil outlet pipe is fixedly connected to the bottom side wall of the oil reservoir. An oil supply hose is installed at the end of the oil outlet pipe furthest from the oil reservoir, and a nozzle is installed at the end of the oil supply hose furthest from the bearing. The pressure of the pressure plate forces the mechanical oil in the oil reservoir out through the oil outlet pipe, then transported through the oil supply hose, and finally sprayed out through the nozzle and injected into the mechanical equipment.

[0010] In one or more embodiments of this utility model, a push handle is fixedly connected to the mounting plate at the edge of the side wall, allowing the operator to move the device by pushing the handle. A storage box is fixedly connected to the mounting plate for storing oil-related parts and tools to facilitate oil filling operations.

[0011] In one or more embodiments of this utility model, a first sealing layer is provided on the side wall of the oil pressure plate. The first sealing layer abuts against the inner side wall of the oil storage tank. Under the action of the first sealing layer, when the oil pressure plate moves in the oil storage tank, there is a good seal between the oil pressure plate and the inner side wall of the oil storage tank, thereby ensuring that the mechanical oil will not leak out through the oil storage tank and the oil pressure plate when the oil pressure plate squeezes the mechanical oil.

[0012] In one or more embodiments of this utility model, a second sealing layer is provided on the inner sidewall of the mounting hole of the pressure plate. The second sealing layer abuts against the outer sidewall of the oil delivery pipe, so that when the pressure plate slides on the oil delivery pipe, there is a good seal between the mounting hole of the pressure plate and the oil delivery pipe. The lower end of the oil delivery pipe is close to the bottom of the oil storage tank to facilitate the delivery of mechanical oil to the area below the pressure plate. A limit ring is provided at the bottom of the pressure plate to limit the distance the pressure plate moves within the oil storage tank and prevent the pressure plate from detaching from the lower end of the oil delivery pipe.

[0013] In one or more embodiments of this utility model, a limiting rod is fixedly connected between the top and bottom wall panels of the oil storage tank. The limiting rod passes through the pressure plate, and the pressure plate can slide on the limiting rod. The limiting rod ensures that the threaded push rod drives the pressure plate to move stably inside the oil storage tank.

[0014] In one or more embodiments of this utility model, the threaded push rod is threadedly connected to the top wall plate of the oil reservoir in a through manner, allowing the threaded push rod to move up and down within the oil reservoir by rotating on the top wall plate. A bearing is installed on the pressure plate, with the lower end of the threaded push rod sleeved within the bearing, and the upper end of the threaded push rod positioned outside the oil reservoir. Thus, by rotating and moving up and down on the top wall plate of the oil reservoir, the threaded push rod can push or pull the pressure plate downwards or upwards within the oil reservoir, thereby achieving the movement of the pressure plate within the oil reservoir via the threaded push rod. Simultaneously, the bearing on the pressure plate ensures that the rotation of the threaded push rod can drive the movement of the pressure plate.

[0015] In one or more embodiments of this utility model, the threaded push rod is threadedly connected to the pressure plate in a through manner. The lower end of the threaded push rod abuts near the bottom of the oil reservoir. A bearing is installed on the upper wall of the oil reservoir, and the upper end of the threaded push rod passes through the bearing and is positioned on the outside of the oil reservoir. This allows the threaded push rod to rotate on the top wall of the oil reservoir. During rotation, due to the threaded connection between the threaded push rod and the pressure plate, the rotation of the threaded push rod can drive the pressure plate to move up and down within the oil reservoir.

[0016] In one or more embodiments of this utility model, a driving block is fixedly connected to the upper end of the threaded push rod, and a rotating handle is sleeved on the driving block. Rotating the rotating handle drives the driving block to rotate, which in turn drives the threaded push rod to rotate. The rotation of the threaded push rod is facilitated by the rotating handle. A snap-fit ​​groove is provided on the side wall of the driving block, allowing the driving block to rotate by sleeved rod within the snap-fit ​​groove, thus enabling rotation of the driving block through multiple methods.

[0017] In one or more embodiments of this utility model, an oil inlet funnel is fixedly connected to the top wall panel of the oil tank at the inlet position. A first filter screen and a second filter screen are detachably installed from top to bottom inside the oil inlet funnel. Each of the first and second filter screens has a fixed disassembly handle. A sealing cap is screwed onto the oil inlet funnel. When oil is injected into the oil tank through the oil inlet funnel, the first and second filter screens can filter the machine oil entering the tank, ensuring that the machine oil entering the tank is clean. The disassembly handles facilitate the installation and removal of the first and second filter screens, making it easy to clean impurities from the first and second filter screens.

[0018] In one or more embodiments of this utility model, a first switching valve is installed on the oil delivery hose, which controls the opening and closing of the oil delivery hose. A support frame is fixedly connected to the mounting plate, and the oil delivery hose is snapped onto the support frame. The support frame supports the oil delivery hose, making it convenient to use. An oil drain pipe is fixedly connected to the side wall of the oil outlet pipe, and a second switching valve is installed on the oil drain pipe. The remaining mechanical oil in the oil storage tank can be drained through the oil drain pipe, and the second switching valve controls the opening and closing of the oil drain pipe.

[0019] Compared with the prior art, this utility model uses a threaded push rod to drive the movement of the pressure plate, thereby squeezing the mechanical oil in the oil tank and injecting the mechanical oil into the mechanical device. This results in lower pressure during oil injection and easier pressure adjustment, thus ensuring safe oil injection. Furthermore, the oil injection device has a simple structure, resulting in lower manufacturing and maintenance costs. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0032] like Figures 1-4 As shown, an embodiment of the present invention provides an oiling device for mechanical equipment maintenance, comprising a support assembly 1 and an oiling device body 2.

[0033] like Figures 1-4 As shown, the support assembly 1 includes a mounting plate 11, which is used for mounting equipment and components.

[0034] like Figures 1-4 As shown, a push handle 12 is fixedly connected to the mounting plate 11 at the edge of the side wall, allowing the operator to move the device by pushing the handle 12. A storage box 13 is fixedly connected to the mounting plate 11, which is used to store oil-related parts and tools for oiling operations.

[0035] like Figures 1-4As shown, the oil injection device body 2 includes an oil storage tank 21, which is used for storing and transporting mechanical oil. The oil storage tank 21 is fixedly connected to the mounting plate 11 so that the mounting plate 11 supports the oil storage tank 21 and ensures stability when the mounting plate 11 moves the oil storage tank 21. An oil pressure plate 22 is installed inside the oil storage tank 21 in a vertically movable manner. By moving the oil pressure plate 22 within the mounting plate 11, the mechanical oil inside the mounting plate 11 can be squeezed, so that the mechanical oil is injected into the mechanical equipment under the pressure of the oil pressure plate 22. Threaded push rods 23 are installed on the top wall plate of the oil storage tank 21 and on the oil pressure plate 22. The oil pressure plate 22 is driven to move within the oil storage tank 21 to achieve the squeezing of the mechanical oil in the oil storage tank 21 by the oil pressure plate 22. An oil delivery pipe 24 is fixedly connected to the inner side wall of the top panel of the oil reservoir 21 at the position of the inlet, allowing oil injected through the inlet of the oil reservoir 21 to flow through the oil delivery pipe 24. A mounting hole is provided at the center of the pressure plate 22, through which the pressure plate 22 is fitted onto the oil delivery pipe 24, ensuring that the installation of the oil delivery pipe 24 does not affect the sliding of the pressure plate 22 within the oil reservoir 21. Simultaneously, the oil delivery pipe 24 ensures that the mechanical oil injected into the oil reservoir 21 is located below the pressure plate 22. An oil outlet pipe 217 is fixedly connected to the bottom of the side wall of the oil reservoir 21. An oil delivery hose 218 is installed at the end of the oil outlet pipe 217 away from the oil reservoir 21, and a nozzle is installed at the end of the oil delivery hose 218 away from the bearing 27. Through the pressure of the pressure plate 22, the mechanical oil in the oil reservoir 21 is discharged through the oil outlet pipe 217, then transported through the oil delivery hose 218, and finally sprayed out through the nozzle and injected into the mechanical equipment. Oil is injected into the mechanical equipment by squeezing the oil through the pressure plate 22, resulting in lower injection pressure. The squeezing force from the pressure plate 22 also facilitates pressure adjustment. Furthermore, the oil delivery hose 218 is a flexible hose, allowing the nozzle to be easily adjusted according to the location of the equipment's oil inlet, thus improving the device's practicality.

[0036] like Figure 4 Combination Figure 6 As shown, a first sealing layer 25 is provided on the side wall of the pressure plate 22. The first sealing layer 25 abuts against the inner side wall of the oil storage tank 21. Under the action of the first sealing layer 25, when the pressure plate 22 moves in the oil storage tank 21, there is a good seal between the pressure plate 22 and the inner side wall of the oil storage tank 21, thereby ensuring that the mechanical oil will not leak out through the oil storage tank 21 and the pressure plate 22 when the pressure plate 22 squeezes the mechanical oil.

[0037] like Figure 4 Combination Figure 6As shown, a second sealing layer 26 is provided on the inner wall of the mounting hole of the pressure plate 22. The second sealing layer 26 abuts against the outer wall of the oil supply pipe 24, so that when the pressure plate 22 slides on the oil supply pipe 24, there is a good seal between the mounting hole of the pressure plate 22 and the oil supply pipe 24. The lower end of the oil supply pipe 24 is close to the bottom of the oil reservoir 21 to facilitate the delivery of mechanical oil to the area below the pressure plate 22 through the oil supply pipe 24. A limit ring 211 is provided at the bottom of the pressure plate 22 to limit the distance the pressure plate 22 moves within the oil reservoir 21 and prevent the pressure plate 22 from detaching from the lower end of the oil supply pipe 24.

[0038] like Figure 4 As shown, a limiting rod 223 is fixedly connected between the top and bottom wall panels of the oil reservoir 21. The limiting rod 223 passes through the pressure plate 22, and the pressure plate 22 can slide on the limiting rod 223. The limiting rod 223 makes the threaded push rod 23 move the pressure plate 22 stably within the oil reservoir 21.

[0039] like Figure 1 and Figure 8 As shown, a drive block 28 is fixedly connected to the upper end of the threaded push rod 23. A rotating handle 29 is sleeved on the drive block 28. Rotating the handle 29 drives the drive block 28 to rotate, which in turn drives the threaded push rod 23 to rotate. The rotation of the threaded push rod 23 is convenient through the rotation of the handle 29. A snap-fit ​​groove 210 is provided on the side wall of the drive block 28, so that the drive block 28 can also be rotated by sleeved rod in the snap-fit ​​groove 210. This allows the rotation of the drive block 28 to be achieved through multiple means.

[0040] like Figure 4 Combination Figure 5 As shown, an oil inlet funnel 212 is fixedly connected to the top wall panel of the oil tank 21 at the inlet position. A first filter screen 213 and a second filter screen 214 are detachably installed from top to bottom inside the oil inlet funnel 212. Both the first filter screen 213 and the second filter screen 214 are fixedly connected to a disassembly handle 215. A sealing cap 216 is screwed onto the oil inlet funnel 212. When oil is injected into the oil tank 21 through the oil inlet funnel 212, the first filter screen 213 and the second filter screen 214 can filter the machine oil entering the oil tank 21, ensuring that the machine oil entering the oil tank 21 is clean. The disassembly handle 215 makes it easy to disassemble and assemble the first filter screen 213 and the second filter screen 214, facilitating the cleaning of impurities from the first filter screen 213 and the second filter screen 214.

[0041] like Figure 2As shown, a first switching valve 219 is installed on the oil delivery hose 218, which controls the opening and closing of the oil delivery hose 218. A support frame 222 is fixedly connected to the mounting plate 11, and the oil delivery hose 218 is snapped onto the support frame 222. The support frame 222 supports the oil delivery hose 218, making it easy to use. An oil drain pipe 220 is fixedly connected to the side wall of the oil outlet pipe 217, and a second switching valve 221 is installed on the oil drain pipe 220. The remaining mechanical oil in the oil storage tank 21 can be drained through the oil drain pipe 220, and the second switching valve 221 controls the opening and closing of the oil drain pipe 220.

[0042] Example 1

[0043] like Figure 4 Combination Figure 6 As shown, the threaded push rod 23 is threadedly connected to the top wall plate of the oil reservoir 21 in a through manner, allowing the threaded push rod 23 to move up and down within the oil reservoir 21 by rotating on the top wall plate. A bearing 27 is installed on the pressure plate 22, and the lower end of the threaded push rod 23 is sleeved within the bearing 27, while the upper end of the threaded push rod 23 is positioned outside the oil reservoir 21. Thus, by rotating and moving up and down on the top wall plate of the oil reservoir 21, the threaded push rod 23 can push or pull the pressure plate 22 downwards or upwards within the oil reservoir 21, thereby enabling the pressure plate 22 to move within the oil reservoir 21 via the threaded push rod 23. Simultaneously, the bearing 27 on the pressure plate 22 allows the rotation of the threaded push rod 23 to drive the movement of the pressure plate 22.

[0044] In this embodiment, the threaded push rod 23 is threadedly connected to the top wall of the oil reservoir 21, so that the movement of the threaded push rod 23 relative to the top wall of the oil reservoir 21 drives the pressure plate 22 to move inside the oil reservoir 21. Therefore, during use, the threaded push rod 23 needs to move up and down on the top wall of the oil reservoir 21. When the oil reservoir 21 is full of oil, the threaded push rod 23 is at its highest point, so the rotation of the threaded push rod 23 needs to be at a higher position.

[0045] Example 2

[0046] like Figure 7 Combination Figure 8 As shown, the threaded push rod 23 is threadedly connected to the pressure plate 22 in a through manner. The lower end of the threaded push rod 23 is close to the bottom of the oil reservoir 21. A bearing 27 is installed on the upper wall of the oil reservoir 21. The upper end of the threaded push rod 23 passes through the bearing 27 and is positioned on the outside of the oil reservoir 21. This allows the threaded push rod 23 to rotate on the top wall of the oil reservoir 21. During rotation, due to the threaded connection between the threaded push rod 23 and the pressure plate 22, the rotation of the threaded push rod 23 can drive the pressure plate 22 to move up and down inside the oil reservoir 21.

[0047] In this embodiment, by threading the threaded push rod 23 to the oil pressure plate 22, the rotation of the threaded push rod 23 allows the oil pressure plate 22 to move up and down within the oil reservoir 21 under the action of the thread. This method prevents the threaded push rod 23 from moving up and down during use, making it convenient to rotate. However, the mechanical oil in the oil reservoir 21 will come into contact with the threaded push rod 23, increasing the risk of mechanical oil contamination.

[0048] In use, by rotating the threaded push rod 23 to position the pressure plate 22 at its highest point inside the oil reservoir 21, machine oil can be injected into the oil reservoir 21 through the oil inlet funnel 212. During injection, the first filter screen 213 and the second filter screen 214 will filter the machine oil respectively. The filtered machine oil is then transported to the oil reservoir 21 through the oil delivery pipe 24. After the oil injection is completed, the mounting plate 11 is moved by pushing the handle 12. When the mounting plate 11 is moved to the mechanical equipment that needs to be oiled, the nozzle and the mechanical equipment are connected by pulling the oil delivery hose 218. The oil filler is connected, and then by rotating the threaded push rod 23, the threaded push rod 23 drives the pressure plate 22 to move, so that the pressure plate 22 squeezes the mechanical oil in the oil tank 21. The squeezed mechanical oil can then flow out through the oil outlet pipe 217. When the first switch valve 219 is opened, the mechanical oil can be delivered to the nozzle through the oil delivery hose 218, so that the nozzle injects the mechanical oil into the mechanical equipment. The pressure of the pressure plate 22 on the mechanical oil can be adjusted by rotating the threaded push rod 23, so that the pressure during oil injection can be adjusted.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
