Description

Technical Field

[0001] This utility model belongs to the field of lubricating oil filling technology, and relates to an adjustable lubricating oil filling device. Background Technology

[0002] Lubricating oil is the lubricating medium for mechanical equipment and is widely used in various types of machinery. In practical applications, the produced lubricating oil needs to be filled into designated containers for storage using lubricating oil filling equipment.

[0003] The existing patent document with authorization publication number CN221544173U discloses a high-efficiency lubricating oil filling machine, which belongs to the field of filling machine technology. It includes a frame, an mounting bracket fixedly installed on the upper end of the frame, two filling heads movably arranged in the mounting bracket, a switching mechanism provided on the two filling heads, and the upper ends of the two filling heads connected to an oil storage tank through a delivery pump.

[0004] However, the aforementioned existing technologies still have the following problems:

[0005] 1. Air ingress causes bubble formation.

[0006] When the filling head is suspended above the oil storage tank, the filling system is not sealed properly, and air can easily mix into the oil through gaps (such as loose pipe joints or poor valve sealing), forming bubbles and affecting the use of lubricating oil.

[0007] 2. Liquid surface impact causes bubble rupture and secondary pollution.

[0008] Design issue: When the height difference between the filling head and the oil level in the reservoir is too large, the kinetic energy of the lubricating oil when it falls freely and impacts the liquid surface is too high, causing splashing and turbulence, resulting in bubble rupture and oil emulsification. The micron-sized aerosols released by the ruptured bubbles may adsorb impurities (such as metal fragments or moisture), forming oxidation nuclei and accelerating oil deterioration. Utility Model Content

[0009] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable lubricating oil filling device to solve the problems mentioned in the background art. This utility model can effectively reduce the air bubbles generated during lubricating oil filling, improve the filling quality of lubricating oil, and reduce the impact on the subsequent use of lubricating oil.

[0010] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0011] An adjustable lubricating oil filling device includes a base and an oil storage tank, wherein a filling component and a sealing component are provided on the top of the base;

[0012] The filling components include:

[0013] The long conveying pipe extends to 3-5 cm above the liquid surface in the oil storage tank, and the long conveying pipe is connected to the metering pump at the top of the oil storage tank through a hose.

[0014] The lifting and adjusting mechanism includes a mounting plate and a motor. A vertical groove is opened on one side of the mounting plate, and a lifting block is slidably arranged in the groove. A long conveying pipe is fixed to one end of the lifting block extending to the outside of the groove. The motor is fixed to the top of the mounting plate. The output shaft of the motor is connected to a threaded rod. The lifting block has a threaded hole for the threaded rod to pass through and which is adapted to its thread.

[0015] The sealing assembly includes a sealing plate and two counterweights. The sealing plate is slidably mounted on one side of the mounting plate, and the two counterweights are symmetrically fixed on the top of the sealing plate. The sealing plate has through holes that fit tightly against the outer wall of the conveying pipe, forming a sliding sealing interface.

[0016] Furthermore, symmetrically arranged guide blocks are fixed on the lifting block, and guide grooves are opened on both sides of the inner side wall of the slide groove. The guide blocks are slidably installed in the corresponding guide grooves.

[0017] Furthermore, two symmetrically arranged T-shaped blocks are fixed to one end of the sealing plate, and two T-shaped grooves are vertically opened on one side of the mounting plate for the two corresponding T-shaped blocks to be embedded.

[0018] Furthermore, a sealing rubber gasket is fixed to the bottom of the sealing plate, and the through hole penetrates the sealing rubber gasket.

[0019] Furthermore, the lifting adjustment mechanism includes a mounting frame, a lifting cylinder, and a placement plate. The mounting frame is fixed to the top of the base, the placement plate is slidably installed in the mounting frame, the lifting cylinder is fixed to the top wall of the base, the telescopic rod of the lifting cylinder is fixed to the bottom of the placement plate, the material conveying pipe is fixed on the mounting frame, and the sealing plate is slidably installed in the mounting frame and located below the material conveying pipe.

[0020] The sealing assembly includes two guide rods and a sealing cover. The two guide rods are symmetrically fixed on the top of the sealing cover. The top of the mounting bracket has two guide holes for the two guide rods to pass through. A stop block is fixed at one end of each guide rod outside the guide hole. The sealing cover has an adjustment hole that fits tightly against the outer wall of the conveying pipe to form a sliding sealing interface.

[0021] Furthermore, two symmetrically arranged limiting blocks are fixed on the placement plate, and limiting grooves are opened on both inner side walls of the mounting frame. The two limiting blocks are slidably arranged in the two corresponding limiting grooves. Springs are sleeved on both guide rods, and the two ends of the springs are fixed to the mounting frame and the top of the sealing plate, respectively.

[0022] The beneficial effects of this utility model are:

[0023] 1. When the oil storage tank is empty, the conveying pipe is close to the bottom of the tank. Filling at this time can prevent air bubbles from entering the lubricating oil, thus ensuring the quality of the filled lubricating oil. Through the cooperation of the sliding sealing plate (T-groove guide) and the sealing rubber gasket, dynamic compensation sealing is achieved when the conveying pipe is raised and lowered, greatly reducing the amount of air mixed in. During filling, the constraint mechanism driven by the threaded rod keeps the distance between the discharge end of the conveying pipe and the liquid surface of the oil storage tank stably controlled at 3-5cm. Compared with the free fall filling method, the impact energy of the liquid surface is reduced, effectively improving the filling quality of the lubricating oil and reducing the impact on the subsequent use of the lubricating oil.

[0024] 2. The linkage structure between the placement plate and the sealing cap driven by the cylinder ensures that the inlet of the oil storage tank is always in contact with the sealing cap, greatly reducing the amount of air mixed in and improving the filling quality. At the same time, the placement plate driven by the cylinder keeps the distance between the discharge end of the conveying pipe and the liquid surface of the oil storage tank stably controlled at 3-5cm. Compared with the free fall filling method, the impact energy of the liquid surface is reduced, effectively improving the filling quality of lubricating oil and reducing the impact on the subsequent use of lubricating oil.

[0036] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0037] Example 1: As Figure 1-6 As shown, an adjustable lubricating oil filling device includes a base 1 and an oil storage tank 2, wherein the top of the base 1 is provided with a filling component and a sealing component;

[0038] The filling components include:

[0039] The long conveying pipe 3 extends to 3-5 cm above the liquid surface in the oil storage tank. The long conveying pipe 3 is connected to the metering pump 5 at the top of the oil storage tank 2 via a hose 4.

[0040] The lifting and adjusting mechanism includes a mounting plate 6 and a motor 7. A vertical groove 8 is opened on one side of the mounting plate 6. A lifting block 9 is slidably arranged in the groove 8. A guide block 15 is fixed on the lifting block 9. Guide grooves 16 are opened on both sides of the inner side wall of the groove 8. The guide block 15 is slidably installed in the corresponding guide groove 16. A long conveying pipe 3 is fixed to one end of the lifting block 9 extending to the outside of the groove 8. The motor 7 is fixed to the top of the mounting plate 6. The output shaft of the motor 7 is connected to a threaded rod 10. The lifting block 9 has a threaded hole 11 for the threaded rod 10 to pass through and to be adapted to its thread.

[0041] The sealing assembly includes a sealing plate 12 and two counterweights 13. The sealing plate 12 is slidably mounted on one side of the mounting plate 6. The two counterweights 13 are symmetrically fixed on the top of the sealing plate 12. The sealing plate 12 has through holes 14 that fit tightly against the outer wall of the conveying pipe 3 to form a sliding sealing interface. Two symmetrically arranged T-shaped blocks 17 are fixed at one end of the sealing plate 12. Two T-shaped grooves 18 are vertically opened on one side of the mounting plate 6 for the two corresponding T-shaped blocks 17 to be embedded. A sealing rubber gasket 19 is fixed at the bottom of the sealing plate 12, and the through holes 14 penetrate the sealing rubber gasket 19.

[0042] The specific operation method of Embodiment 1 of this utility model is as follows:

[0043] Place the oil storage tank to be filled on the base 1 and align the inlet of the oil storage tank with the conveying pipe 3.

[0044] Lifting and Adjustment Operation

[0045] The starting motor 7 drives the threaded rod 10 to rotate, causing the lifting block 9 to move vertically along the slide 8. The clearance fit between the guide block 15 and the guide groove 16 in the slide 8 ensures the accuracy of linear motion, and causes the end of the conveying pipe 3 to enter the oil storage tank, so that the end of the conveying pipe 3 is close to the bottom of the oil storage tank, at which point filling is carried out.

[0046] The lifting block 9 drives the conveying pipe 3 to move up and down at a uniform speed, so that the distance between the end of the conveying pipe 3 and the liquid surface of the oil storage tank is stably controlled at 3-5cm.

[0047] Adaptive sealing process

[0048] The sealing plate 12 is pressed down by the gravity of the counterweight 13, so that the sealing plate 12 always abuts against the feed inlet of the oil storage tank and seals the feed inlet, reducing the amount of air mixed in.

[0049] Embodiment 1 of this utility model: When the oil storage tank is not filled, the conveying pipe 3 is close to the bottom of the oil storage tank. Filling at this time can prevent air bubbles from entering the lubricating oil to a certain extent, thereby ensuring the quality of the filled lubricating oil. Through the cooperation structure of the sliding sealing plate 12 (guided by T-groove 18) and the sealing rubber gasket 19, dynamic compensation sealing is achieved when the conveying pipe 3 rises and falls, greatly reducing the amount of air mixed in. During filling, the distance between the discharge end of the conveying pipe 3 and the liquid surface of the oil storage tank is stably controlled at 3-5cm by the constraint mechanism driven by the threaded rod 10. Compared with the free fall filling method, the impact energy of the liquid surface is reduced, effectively improving the filling quality of the lubricating oil and reducing the impact on the subsequent use of the lubricating oil.

[0050] Example 2: Figure 7-9 As shown, the lifting adjustment mechanism includes a mounting frame 20, a lifting cylinder 21, and a placement plate 22. The mounting frame 20 is fixed to the top of the base 1, the placement plate 22 is slidably installed in the mounting frame 20, the lifting cylinder 21 is fixed to the top wall of the base 1, the telescopic rod of the lifting cylinder 21 is fixed to the bottom of the placement plate 22, the material conveying pipe 3 is fixed on the mounting frame 20, and the sealing plate 12 is slidably installed in the mounting frame 20 and located below the material conveying pipe 3.

[0051] The sealing assembly includes two guide rods 23 and a sealing cover 24. The two guide rods 23 are symmetrically fixed on the top of the sealing cover 24. The mounting bracket 20 has two guide holes 26 on its top for the two guide rods 23 to pass through. A stop block 25 is fixed at one end of the guide rod 23 outside the guide hole 26. The sealing cover 24 has an adjustment hole that fits tightly against the outer wall of the conveying tube 3 to form a sliding sealing interface.

[0052] Two symmetrically arranged limiting blocks 27 are fixed on the placement plate 22. Limiting grooves 28 are opened on both inner side walls of the mounting frame 20. The two limiting blocks 27 are slidably arranged in the two corresponding limiting grooves 28. Springs 29 are sleeved on both guide columns. The two ends of the springs 29 are fixed to the top of the mounting frame 20 and the sealing plate 12, respectively.

[0053] The specific operation method of Embodiment 2 of this utility model is as follows:

[0054] Before filling, place the oil storage tank to be filled on the placement plate 22, and align the inlet of the oil storage tank with the conveying pipe 3.

[0055] The lifting cylinder 21 drives the placement plate 22 to move vertically along the limiting groove 28, and the placement plate 22 drives the oil storage tank to rise to 3-5cm below the end of the conveying pipe 3.

[0056] At the same time, the inlet of the oil storage tank is brought into contact with the bottom of the sealing cover 24. When the oil storage tank rises, the sealing cover 24 rises synchronously. The sealing cover 24 drives the two guide columns to move along the guide hole 26. At this time, the spring 29 is compressed and has a certain elastic potential energy. Under the action of the spring 29, the spring 29 applies a force to the sealing cover 24, so that the sealing cover 24 can better seal the inlet of the oil storage tank.

[0057] During filling, the drive cylinder drives the placement plate 22 to descend at a constant speed, and the placement plate 22 drives the oil storage tank to descend at a constant speed, so that the distance between the end of the conveying pipe 3 and the liquid surface of the oil storage tank is stably controlled at 3-5cm. At the same time, under the action of the spring 29, the sealing cover 24 is always in contact with the oil storage tank inlet during the descent of the oil storage tank.

[0058] After filling, the drive cylinder drives the placement plate 22 to descend at a constant speed, and the placement plate 22 drives the oil storage tank to descend at a constant speed, so that the oil storage tank is separated from the sealing cover 24, and the conveying pipe 3 is located outside the oil storage tank, and the oil storage tank is located below the conveying pipe 3. The oil storage tank can then be removed.

[0059] In the second embodiment of this utility model, the linkage structure between the placement plate 22 and the sealing cover 24 driven by the cylinder ensures that the inlet of the oil storage tank is always in contact with the sealing cover 24, greatly reducing the amount of air mixed in and improving the filling quality. At the same time, the placement plate 22 driven by the cylinder ensures that the distance between the discharge end of the conveying pipe 3 and the liquid surface of the oil storage tank is stably controlled at 3-5cm. Compared with the free fall filling method, the impact energy of the liquid surface is reduced, effectively improving the filling quality of lubricating oil and reducing the impact on the subsequent use of lubricating oil.

[0060] 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.
