Description

Technical Field

[0001] This utility model belongs to the technical field of fuel dispensers, specifically relating to a lubricating oil dispensing device. Background Technology

[0002] In the fields of industrial production and equipment maintenance, adding lubricating oil is a crucial step in ensuring the normal operation of equipment.

[0003] Currently, traditional lubricating oil filling devices generally suffer from a lack of diverse pipeline designs, only meeting the filling needs of fixed scenarios and failing to adapt to the flexible requirements of different equipment and varying filling volumes. For example, when adding small amounts of lubricating oil to equipment, the lack of a targeted observation structure makes it difficult for operators to intuitively grasp the actual filling volume, easily leading to insufficient filling causing accelerated equipment wear, or excessive filling resulting in lubricating oil waste and environmental pollution.

[0004] In addition, the oil hoppers in traditional devices are mostly fixed connections, making disassembly cumbersome. After long-term use, the oil stains and impurities remaining inside are difficult to clean thoroughly. When used again, they can easily contaminate the newly injected lubricating oil, affecting the lubrication effect, and may even cause malfunctions due to contaminants entering the equipment.

[0005] To address this technical problem, a lubricating oil filling device is provided. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a lubricating oil filling device to solve the problems of existing filling devices, such as simple pipeline design, difficulty in observing and controlling the filling amount, and difficulty in cleaning the oil hopper.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A lubricating oil filling device includes a base frame with directional wheels and self-locking casters at the bottom. A support frame A and a support frame B are fixedly installed on the upper surface of the base frame. An oil pump is fixedly installed inside the support frame B. The oil pump's discharge end is connected to an oil filling pipe, and the oil pump's filling end is connected to a three-way valve. The two oil inlet ends of the three-way valve are respectively connected to an oil inlet pipe A and an oil inlet pipe B. An oil storage hopper is detachably installed at the oil inlet end of the oil inlet pipe B. The oil storage hopper is made of transparent polyethylene and is snap-fitted into the support frame B. A hydraulic drive device for driving the oil pump is fixedly installed on the support frame A.

[0009] In the above technical solution, the driving device includes a motor and a reducer. The motor and the reducer are both fixedly mounted on the upper surface of the support frame A. The power output end of the reducer is fixedly connected to the power input end of the oil pump. Synchronous pulleys are sleeved on the outer surface of the power input shaft of the reducer and the outer surface of the output shaft of the motor. A synchronous belt is installed between the two synchronous pulleys.

[0010] In the above technical solution, the oil inlet pipeline A includes an L-shaped metal pipe and a hose. The oil outlet end of the L-shaped metal pipe is connected to a three-way valve, one end of the hose is connected to the oil inlet end of the L-shaped metal pipe, and the other end of the hose is used to insert into an external lubricating oil tank.

[0011] In the above technical solution, the oil inlet pipe B includes a T-shaped pipe, the lower end of which is connected to a three-way valve, and an external locking sleeve is fitted on the outer surface of the T-shaped pipe. The external locking sleeve is screwed onto the outer surface of the oil discharge end of the oil storage hopper, and sealing rings are installed between the external locking sleeve and the T-shaped pipe and the oil discharge end of the oil storage hopper, respectively.

[0012] In the above technical solution, L-shaped hinges are fixedly installed on both the left and right surfaces of the support frame, and a shaft is rotatably installed between the two L-shaped hinges. A dust cover is fitted on the outer surface of the shaft, and the dust cover seals the upper opening of the oil storage hopper.

[0013] The lubricating oil filling device of this utility model has the following advantages compared with the prior art:

[0014] This invention achieves flexible switching between large and small-volume filling by setting a three-way valve to connect oil inlet pipe A and oil inlet pipe B, solving the problem of simple pipeline design. By using a transparent polyethylene oil storage hopper, the filling amount can be easily observed, avoiding insufficient or excessive filling. The oil storage hopper is installed in a detachable manner, which facilitates disassembly and cleaning, preventing residual oil and impurities from contaminating new oil. At the same time, in conjunction with other structural designs, the practicality and reliability of the device are further improved. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0022] A lubricating oil filling device, combined with Figure 1 As shown, the system includes a base frame 1 with directional wheels and self-locking casters at the bottom. Support frame A2 and support frame B3 are fixedly installed on the upper surface of the base frame 1. An oil pump 4 is fixedly installed inside the support frame B3. The oil discharge end of the oil pump 4 is connected to an oil injection pipe 41, and the oil injection end of the oil pump 4 is connected to a three-way valve 42. The two oil inlet ends of the three-way valve 42 are respectively connected to an oil inlet pipe A5 and an oil inlet pipe B6. An oil storage hopper 7 is detachably installed at the oil inlet end of the oil inlet pipe B6. The oil storage hopper 7 is made of transparent polyethylene and is snapped into the support frame B3. A hydraulic drive device 8 for driving the oil pump 4 is fixedly installed on the support frame A2.

[0023] The design of the three-way valve 42 enables the switching function of the oil inlet pipeline. When a large amount of oil needs to be added, it can be switched to the oil inlet pipeline A5 to connect to the external oil tank. When adding a small amount of oil, it can be switched to the oil inlet pipeline B6 to use the oil storage hopper 7, which improves the versatility of the device. The transparent polyethylene oil storage hopper 7 allows operators to intuitively observe the internal oil level and accurately control the amount of oil added, avoiding overfilling or underfilling. In addition, polyethylene is resistant to lubricating oil corrosion and is lightweight. Combined with the snap-fit ​​installation method, it not only ensures that the oil storage hopper 7 is installed firmly, but also facilitates quick and easy loading and unloading. The drive device 8 provides power to the oil pump 4, ensuring that the lubricating oil can be stably delivered to the oil filling pipe 41.

[0024] It should be noted that, as Figure 1As shown, the drive device 8 includes a motor 81 and a reducer 82. Both the motor 81 and the reducer 82 are fixedly mounted on the upper surface of the support frame A2 by bolts. The power output end of the reducer 82 is fixedly connected to the power input end of the oil pump 4. Synchronous pulleys 83 are fitted on the outer surface of the power input shaft of the reducer 82 and the outer surface of the output shaft of the motor 81. A synchronous belt 84 is installed between the two synchronous pulleys 83.

[0025] The motor 81 provides continuous driving force as a power source. Its connection switch and power cord are used to connect to an external power source. The reducer 82 can convert the high-speed output of the motor 81 into a low-speed power suitable for the oil pump 4, avoiding problems such as excessive lubricating oil delivery pressure, splashing, or pipeline impact caused by excessive speed of the oil pump 4, and ensuring a smooth filling process. The cooperation between the synchronous pulley 83 and the synchronous belt 84 is a flexible transmission, which is quieter than gear transmission. In the event of overload, the synchronous belt 84 will slip, which can protect the motor 81 and the oil pump 4 from damage. At the same time, the transmission efficiency is high and the maintenance cost is low. Only the tightness of the synchronous belt 84 needs to be checked periodically.

[0026] Specifically, combined Figure 1 and Figure 3 As shown, the oil inlet pipe A5 includes an L-shaped metal pipe 51 and a hose 52. The oil outlet end of the L-shaped metal pipe 51 is connected to the three-way valve 42 through a small flange or pipe connector. One end of the hose 52 is connected to the oil inlet end of the L-shaped metal pipe 51, and the other end of the hose 52 is used to insert into the external lubricating oil tank.

[0027] The L-shaped metal tube 51 has high rigidity, which can firmly connect the three-way valve 42 and maintain the pipeline shape, avoiding pipeline deformation caused by external force or vibration and affecting the smooth flow of oil. In addition, the L-shaped metal tube 51 can avoid the problem of easy bending of the pipeline affecting the flow efficiency when using soft tubes to directly connect with the three-way pipe. The hose 52 is a corrosion-resistant rubber tube with good flexibility. Its free end can be flexibly inserted into external lubricating oil tanks of different sizes and placement positions, solving the problem that metal tubes are difficult to adapt to various oil tanks, greatly improving the adaptability of the device in large-scale filling scenarios. At the same time, the combination of hose 52 and L-shaped metal tube 51 takes into account both pipeline stability and flexibility.

[0028] Specifically, combined Figure 1 and Figure 3As shown, the oil inlet pipe B6 includes a T-shaped pipe 61. The lower end of the T-shaped pipe 61 is connected to the three-way valve 42 through a small flange or pipe connector, which can ensure the vertical transition of the oil circuit and reduce the flow resistance of lubricating oil. The outer surface of the T-shaped pipe 61 is fitted with an external locking sleeve 62, which is screwed onto the outer surface of the oil discharge end of the oil storage hopper 7. The external locking sleeve 62 realizes the detachable connection between the oil storage hopper 7 and the T-shaped pipe 61 through the screw connection. Compared with the fixed connection, it is easier to disassemble and clean the oil storage hopper 7, and avoid the contamination of new oil by residual oil and impurities after long-term use. Sealing rings are installed between the external locking sleeve 62 and the T-shaped pipe 61 and the oil discharge end of the oil storage hopper 7, respectively. The sealing rings can enhance the sealing of the connection between the external locking sleeve 62 and the T-shaped pipe 61 and the oil discharge end of the oil storage hopper 7, effectively preventing the lubricating oil from leaking from the gaps during the transportation process, which not only avoids the waste of lubricating oil, but also prevents oil pollution of the working environment.

[0029] Finally, in order to facilitate dust prevention in the oil storage hopper 7 and ensure the storage quality of lubricating oil, L-shaped hinges 31 are fixedly installed on both the left and right surfaces of the support frame B3. A shaft 32 is rotatably installed between the two L-shaped hinges 31. A dust cover 9 is fitted on the outer surface of the shaft 32 and covers the upper opening of the oil storage hopper 7.

[0030] The L-shaped hinge 31 and the shaft 32 form a rotating structure, allowing the dust cover 9 to be flexibly rotated around the shaft 32. When lubricating oil needs to be added to the oil storage hopper 7, the dust cover 9 can be flipped upwards to open the opening; when not in use, the dust cover 9 is closed to seal the opening of the oil storage hopper 7. This effectively prevents dust, impurities, etc. from falling into the oil storage hopper 7, ensuring the cleanliness of the internal lubricating oil and preventing contaminants from entering the equipment with the lubricating oil and causing malfunctions. At the same time, the flipping operation of the dust cover 9 is convenient and does not affect the normal use of the oil storage hopper 7.
