Abstract
Description
Technical Field
[0001] This invention relates to the field of overhead conveying technology, and more particularly to an overhead conveying device for lubricating oil production. Background Technology
[0002] In the lubricant production process, the transport of oil drums (or lubricant packaging containers) is one of the key logistics links. While traditional ground-based conveying methods can meet basic transport needs, the conveying equipment occupies a significant amount of workshop floor space, limiting production line layout. For production workshops with high ceilings, this results in wasted space resources, narrow logistics channels, and reduced material turnover efficiency. In contrast, overhead conveying systems, by installing dedicated tracks in the ceiling or upper part of the factory building to transport oil drums in a suspended manner, can fully utilize the vertical space of the workshop.
[0003] Currently, the inertial force caused by the start-up and stop of the suspended conveyor, as well as the impact force during movement, can cause the lubricating oil inside the drum to shake and the drum body to tilt. This can easily lead to excessive shaking of the drum body. Shaking of the lubricating oil increases the contact area between the oil and air and the contact becomes more frequent, accelerating oil oxidation and reducing the performance of the lubricating oil. In addition, shaking can also easily lead to uneven and constantly changing pressure distribution of the lubricating oil inside the drum, generating additional pressure impacts on parts such as the drum lid and drum body welds. When the pressure exceeds the bearing capacity of the drum body or sealing parts, it can easily cause the seals to loosen or deform, leading to lubricating oil leakage, thus making the equipment less practical. Summary of the Invention

[0006] Preferably, the connecting assembly includes an electric slide rod slidably connected within a track, a drive motor for driving the electric slide rod is fixedly mounted on the top of the track, and a rotating assembly is provided at the bottom of the electric slide rod.
[0007] Preferably, the rotating assembly includes a connecting shaft, with a second connecting block rotatably connected to both the top and bottom of the connecting shaft, and the two second connecting blocks are respectively fixedly connected to two adjacent first connecting blocks, and the bottom end of the electric slide rod is rotatably connected to the second connecting block at the top of the connecting shaft.
[0008] Preferably, the first connecting block is provided with multiple sets of sliding components. Each sliding component includes a connecting shaft that passes through the first connecting block and is rotatably connected to it. Two pulleys are fixedly installed on the outer wall of the connecting shaft. The two pulleys are symmetrically distributed on both sides of the first connecting block, and the pulleys are in rolling contact with the inner wall of the track.
[0009] Preferably, two angle detectors are fixedly installed on the outer wall of the connecting shaft, and the two angle detectors are symmetrically distributed on the side of the two pulleys that are far apart from each other.
[0010] Preferably, the angle detector is provided with a protective cover, which is fixedly installed on the outer wall of the connecting shaft.
[0011] Preferably, flywheels are fixedly installed at both ends of the connecting shaft, and the flywheels are disposed inside the track and roll in contact with the inner wall of the track.
[0012] Preferably, the support column has an internal mounting cavity, the hook assembly includes a load-bearing hook fixedly installed in the mounting cavity, and the load-bearing hook is fixedly connected to a fixing frame by a hanging rope, and a pressure cap is fixedly installed on the outer wall of the support column by bolts.
[0013] Preferably, a base is fixedly installed on the first fixed plate, the connecting column is rotatably connected to the second fixed plate through a second rotating shaft, a slider is fixedly installed at the end of the first fixed column away from the sliding port, and a sliding groove corresponding to the position of the sliding port is opened on the base, and the slider is slidably connected to the sliding groove.
[0014] Preferably, the transmission assembly includes a push gear fixedly installed on the outer wall of the second rotating shaft, a semi-circular gear is provided below the push gear, the semi-circular gear is rotatably connected to the second fixed plate through the first rotating shaft, and the semi-circular gear meshes with the push gear, a connecting member is rotatably connected to the outer wall of the semi-circular gear, and the end of the connecting member away from the semi-circular gear is rotatably connected to the slider through the second fixed column.
[0015] Compared with the prior art, the advantages of the present invention are as follows: 1. In this invention, when the oil drum tilts, the gravity sensor inside the support column detects the change. The electric damper applies a reverse pulling force by extending one side and contracting the other side, which quickly and effectively balances the tilting trend of the oil drum and prevents the oil drum from tipping over or the oil from leaking due to excessive tilting. The buffer component works in conjunction with the electric damper. When the connecting column rotates and drives the slider to move, the spring can absorb and buffer the energy generated when the oil drum tilts or is impacted, reducing the impact of vibration on the oil drum and the oil inside, and avoiding problems such as excessive oil shaking or even leakage due to vibration.
[0016] 2. In this invention, the slider not only participates in balance adjustment, but also changes the center of gravity distribution of the device during movement, playing the role of counterweight. It can automatically adjust the center of gravity position according to the tilt state of the oil drum to achieve dynamic balance of the oil drum and adapt to different tilt conditions. The slider has both balance adjustment and counterweight functions, which simplifies the structure of the device, reduces the cost and complexity of the device, and improves the working efficiency and performance of the device.
[0017] 3. This invention monitors the angle of the connecting shaft in real time by setting an angle detector. When the connecting shaft is detected to be tilted, the moving speed of the drive motor can be slowed down in time to avoid problems such as poor contact between the pulley and the track and unstable operation caused by the tilt of the connecting shaft. This ensures the smooth operation of the conveying device. The flywheel can store and release kinetic energy during the movement. When the pulley is disturbed by external factors and the energy demand changes suddenly, the flywheel can respond quickly, release or absorb energy, stabilize the operating state of the device, reduce speed fluctuations and vibrations, and help ensure the continuity of material conveying in the lubricating oil production process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0021] Reference Figures 1 to 8A suspended conveying device for lubricating oil production includes a track 1, within which multiple first connecting blocks 5 are arranged. Adjacent first connecting blocks 5 are connected by a connecting assembly, which includes an electric slide rod 8 slidably connected within the track 1. A drive motor 4 for driving the electric slide rod 8 is fixedly mounted on the top of the track 1 (this is prior art and will not be described further). A rotating assembly is provided at the bottom of the electric slide rod 8, including a connecting shaft 7. Second connecting blocks 6 are rotatably connected to both the top and bottom of the connecting shaft 7. The bottom end of the electric slide rod 8 is rotatably connected to the second connecting block 6 at the top of the connecting shaft 7. Each second connecting block 6 is fixedly connected to two adjacent first connecting blocks 5. Multiple sets of sliding components are provided on each first connecting block 5. Each sliding component includes a connecting shaft 3, which passes through and is rotatably connected to the first connecting block 5. Two pulleys 2 are fixedly installed on the outer wall of the connecting shaft 3, symmetrically distributed on both sides of the first connecting block 5. Two angle detectors 10 are fixedly installed on the outer wall of the connecting shaft 3, symmetrically distributed on the side where the two pulleys 2 are furthest apart. The angle detectors 10 monitor the angle of the connecting shaft 3 in real time. Once a tilting problem is detected, they can... The timely slowing down of the drive motor 4 effectively avoids problems such as poor contact between the pulley 2 and the track 1 and unstable operation caused by the tilting of the connecting shaft 3, further ensuring the smoothness and safety of the conveying device's operation. An external protective cover 9 is installed on the angle detector 10, fixedly mounted on the outer wall of the connecting shaft 3. The protective cover 9 provides excellent protection for the angle detector 10, preventing interference and damage from external debris, dust, oil, etc., ensuring that the angle detector 10 can work stably for a long time, accurately detecting changes in the angle of the connecting shaft 3, and providing reliable monitoring data for the stable operation of the conveying device. According to reports, flywheels 11 are fixedly installed at both ends of the connecting shaft 3. Both flywheels 11 and pulleys 2 are set inside the track 1 and roll in contact with the inner wall of the track 1, so that flywheels 11 and pulleys 2 can roll smoothly in the track 1 along its extension direction. Flywheels 11 can store and release kinetic energy during movement. When pulleys 2 are subjected to external interference (such as temporary increase in load) causing a sudden change in energy demand, flywheels 11 can respond quickly, release or absorb energy, stabilize the operating state of the device, reduce speed fluctuations and vibrations, improve the stability and reliability of conveying, and help ensure the continuity of material conveying in the lubricating oil production process.
[0022] The bottom of the first connecting block 5 is rotatably connected to a support column 29. The support column 29 has an installation cavity inside, and a load-bearing hook is fixedly installed inside the installation cavity. The load-bearing hook is fixedly connected to a fixing frame 32 by a hanging rope 31. A pressure cap 30 is fixedly installed on the outer wall of the support column 29 by bolts. The bottom and top of the fixing frame 32 are solid plates, and the middle part is a circular structure. The lubricating oil drum is installed on the fixing frame 32. The support column 29 is equipped with a gravity sensor (not shown in the figure) for real-time monitoring of the weight change of the suspended load. When the oil drum leaks or additional items are added to the fixing frame 32, the gravity sensor can detect the weight change in time, so that the staff can take timely measures to prevent damage to the conveying device and track 1 due to abnormal load.
[0023] Electric dampers 24 are symmetrically rotatably connected to both sides of the support column 29. A horizontally arranged connecting column 23 is rotatably connected to the end of the electric damper 24 away from the support column 29. Buffer assemblies are symmetrically arranged at both ends of the connecting column 23. Each buffer assembly includes a first fixed plate 12 fixedly installed at the bottom of the first connecting block 5. A base 13 and a second fixed plate 14 are fixedly installed on the first fixed plate 12. The connecting column 23 is rotatably connected to the second fixed plate 14 via a second rotating shaft 21. A vertical sliding opening 16 is provided on the second fixed plate 14. A first fixed column 15 is slidably connected to the sliding opening 16. The first fixed column 15 moves linearly along the sliding opening 16. A buffer assembly is fixedly installed on the second fixed plate 14. A locking post 18 is located directly above the first fixed post 15 and is elastically connected to the first fixed post 15 via a spring 17. A slider 27 is fixedly installed on the end of the first fixed post 15 away from the sliding opening 16. A groove 28 corresponding to the position of the sliding opening 16 is provided on the base 13, and the slider 27 is slidably connected to the groove 28. A transmission assembly is provided on the side of the second fixed plate 14 near the connecting post 23. The transmission assembly includes a push gear 22 fixedly installed on the outer wall of the second rotating shaft 21. A semi-circular gear 20 is provided below the push gear 22. The semi-circular gear 20 is rotatably connected to the second fixed plate 14 via the first rotating shaft 19, and the semi-circular gear 20 meshes with the push gear 22. A connector 26 is rotatably connected to the outer wall of the semi-circular gear 20. The end of the connector 26 away from the semi-circular gear 20 is rotatably connected to the slider 27 via a second fixed column 25. When the oil drum tilts, the gravity sensor inside the support column 29 can detect the change in time. Simultaneously, the electric dampers 24 on both sides of the support column 29 activate. The electric damper 24 on the forward direction of the support column 29 extends, while the other electric damper 24 retracts and applies a pulling force to the connecting column 23. By extending on one side and applying a reverse pulling force on the other, the electric dampers 24 quickly and effectively balance the tilting trend of the oil drum, ensuring the stability of the oil drum during movement and preventing it from tipping over due to excessive tilting. In the event of an oil leak, the pulling of the electric damper 24 will cause the connecting column 23 to rotate, thereby driving the push gear 22 to rotate the semi-circular gear 20. The rotation of the push gear 22 will drive the slider 27 to move upward through the connecting piece 26. Simultaneously, the slider 27 will drive the first fixed column 15 to press the spring 17 upward. The cooperation between the spring 17 and the first fixed column 15 plays a role in shock absorption and limiting the movement of the slider 27. The extension and contraction of the spring 17 can buffer the impact force on the device during operation, reducing the impact of vibration on the oil tank and the entire device. At the same time, the limiting function can ensure that the first fixed column 15 and the slider 27 move within a certain range, increasing the reliability and safety of the device. The slider 27 not only participates in balance adjustment but also has a counterweight function, which can enhance the overall stability of the device. When the oil drum is tilted, the movement of the slider 27 and the counterweight effect can effectively prevent the oil drum from shaking beyond the adjustment range of the electric damper 24, further ensuring the stable operation of the oil drum and the device, and reducing the probability of accidents. According to the tilt of the oil drum, through the coordinated action of the electric damper 24 and a series of transmission components, the support column 29 is finely adjusted to the tilt side, precisely limiting the tilt amplitude of the oil drum, avoiding large tilts, improving the device's control over the tilt of the oil drum, and ensuring that the oil drum can maintain a relatively stable state under various working conditions.
[0024] When using this invention, first open the pressure cap 30 to separate it from the support column 29, and place the container filled with lubricating oil into the fixing frame 32 to ensure its position is fixed. Then, connect the fixing frame 32 to the hook inside the support column 29 through the hanging rope 31, close the pressure cap 30 again, and tighten it to the support column 29 with bolts to prevent loosening. The top of the support column 29 is rotatably connected to the bottom of the first connecting block 5. Start the drive motor 4 so that the electric slide bar 8 drives the first connecting block 5 to move synchronously through the second connecting block 6. The connecting shaft 3 on the first connecting block 5 moves accordingly, and the pulleys 2 on both sides of the connecting shaft 3 roll in the track 1 to achieve smooth conveying.
[0025] When pulley 2 slides forward, the oil drum tends to remain stationary due to gravity. However, the forward dragging of pulley 2 causes the oil drum to tilt. When the oil drum tilts, the gravity sensor inside support column 29 detects this change. Simultaneously, the electric damper 24 located in the forward direction of support column 29 extends, while the electric damper 24 on the other side activates and applies a counter-pulling force to balance the tilting tendency of the oil drum. The pulling of the electric damper 24 causes the connecting column 23 connected to it to rotate. The rotation of the connecting column 23 drives the push gear 22 to rotate, which in turn drives the semi-circular gear 20 to rotate. The push gear 22 and the semi-circular gear 20 are respectively mounted on the second fixed shaft 21 and the first rotating shaft 19. On plate 14, the rotation of the drive gear 22 will drive the connecting piece 26 to move. The connecting piece 26 will drive the slider 27 to slide upward in the slide groove 28. The slider 27 is not only used to adjust the balance, but also has a counterweight function to enhance the stability of the device and prevent the oil drum from shaking beyond the adjustment range of the electric damper 24. When the slider 27 moves, the spring 17 suspended on the first fixed column 15 will extend and retract accordingly, while the first fixed column 15 slides along the sliding port 16. The spring 17 plays the role of shock absorption and limit. By rotating the connecting column 23, the shaking of the overall structure can be effectively suppressed to ensure smooth operation. By adjusting the support column 29 to the tilt side, the tilting range of the oil drum is limited to prevent it from tilting significantly.
[0026] When the oil drum passes through track 1, it will be subjected to centrifugal force pointing inwards from track 1. At this time, the first fixed plate 12 and its connecting structure will naturally swing outwards from track 1 under the action of gravity, effectively counteracting the influence of centrifugal force, thereby significantly reducing the tilting and shaking of the device and the conveyed items. When the system is working, the angle detector 10 will monitor the tilt angle of the connecting shaft 3 in real time. When an abnormal tilt is detected, the running speed of the drive motor 4 will be automatically adjusted to slow it down appropriately. At the same time, the sliding of the pulley 2 will drive the flywheel 11 to rotate, using its energy storage characteristics to smooth the energy fluctuation of track 1.
[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
