Roller lugs with lubrication mechanism

Abstract

This utility model belongs to the technical field of roller can ear, specifically relating to a roller can ear with a lubrication mechanism, including a mounting base, a support block connected to the top surface of the mounting base, a fixing plate rotatably connected to the top of the support block, and a roller rotatably connected inside the fixing plate. This utility model utilizes the cooperation between the storage box, oil inlet pipe, groove, filter plate, sealing baffle, threaded rod, and oil inlet groove. Lubricating oil in the storage box passes through the mesh of the filter plate, is guided through the groove, and finally flows into the oil inlet groove. The lubricating oil is then transported along the oil inlet groove to the inside of the support block, where it fully contacts the pin inserted into the support block, achieving comprehensive lubrication of the pin. This avoids the problem of incomplete lubrication caused by insufficient grease coverage when lubricating oil is added from both ends of the pin in traditional methods, thus significantly reducing wear on the pin due to insufficient lubrication and greatly extending the overall service life of the roller can ear.

Description

Technical Field

[0001] This utility model belongs to the technical field of roller can ear, specifically relating to a roller can ear with a lubrication mechanism. Background Technology

[0002] Roller lugs are an important component of vertical shaft hoisting containers, serving as guides and buffers, and are key components ensuring the smooth operation of the hoisting container along the guideway. The roller lugs run along rectangular steel guideways, using the friction between the rollers and the guideways to guide the container, maintaining stability during vertical movement and reducing swaying and deviation. When the hoisting container is subjected to impact, the buffer device absorbs the impact energy and transmits the force to the shock absorber through levers and other mechanisms, thus providing cushioning and stabilization.

[0003] During the use of roller can ears, the fixed plate of the roller and the support block are rotatably connected by a pin. However, after long-term use, lubricating oil needs to be added to ensure stable rotation. However, because the support block has a certain length, lubricating oil can only be added from both ends of the pin. Due to the length limitation of the support block, the lubricating oil cannot completely penetrate the interior of the support block, which will affect the rotation of the pin and greatly reduce the service life of the roller can ear. Utility Model Content

[0004] The purpose of this invention is to provide a roller can ear with a lubrication mechanism, which aims to solve the problem in the prior art that after long-term use, lubricating oil needs to be added to ensure stable rotation. However, because the support block has a certain length, lubricating oil can only be added from both ends of the pin. Due to the length limitation of the support block, the lubricating oil cannot completely penetrate the interior of the support block, which in turn affects the rotation of the pin and greatly reduces the service life of the roller can ear.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller lug with a lubrication mechanism, including a mounting base, a support block connected to the top surface of the mounting base, a fixing plate rotatably connected to the top of the support block, a roller rotatably connected inside the fixing plate, an adjusting oil cylinder rotatably connected to the top of the mounting base, a storage box connected to the back end of the support block, an oil inlet pipe installed on the outer wall of the storage box, a groove penetrating through the inner wall of the storage box, a filter plate installed inside the groove, a sealing baffle inserted inside the filter plate, a threaded rod threadedly connected to the top of the storage box, and an oil inlet groove formed on the surface of the support block.

[0006] In a preferred embodiment of the roller can ear with a lubrication mechanism of this utility model, the filter plate and the sealing baffle are connected in a sealed manner.

[0007] In a preferred embodiment of the roller lug with a lubrication mechanism of this invention, the end of the threaded rod is rotatably connected to the inside of the sealing baffle.

[0008] In a preferred embodiment of the present invention, the oil inlet groove and the groove are of the same size.

[0009] As a preferred embodiment of the roller lubricating mechanism of this utility model, the surface of the mounting base is provided with a sliding groove, a slider is slidably connected inside the sliding groove, an annular block is connected to the top of the slider, and a sealing ring is installed on the inner wall of the annular block.

[0010] As a preferred embodiment of the roller lug with a lubrication mechanism of this utility model, the groove and the slider are adapted to form a cross shape.

[0011] In a preferred embodiment of the roller lug with a lubrication mechanism of this utility model, the inner ring of the sealing ring has the same size as the mounting hole on the surface of the slider.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the coordination of the storage box, oil inlet pipe, groove, filter plate, sealing baffle, threaded rod, and oil inlet groove, the operator first injects lubricating oil into the storage box through the oil inlet pipe. Then, the threaded rod is rotated, causing the sealing baffle to rise synchronously. After the sealing baffle rises, the mesh opening of the filter plate is exposed. At this time, the lubricating oil in the storage box will pass through the mesh opening of the filter plate, then be guided through the groove, and finally flow into the oil inlet groove. Then, the lubricating oil is transported along the oil inlet groove to the inside of the support block and makes full contact with the pin inserted on the support block, achieving full lubrication of the pin. This avoids the problem of incomplete lubrication caused by the grease not being able to cover the entire pin when lubricating oil is added from both ends of the pin in the traditional way. This significantly reduces the wear of the pin caused by insufficient lubrication and greatly extends the overall service life of the roller can ear.

[0013] By using the combination of the slide groove, slider, annular block, and sealing ring, the operator can slide the slider along the slide groove when installing the roller can ear, thereby adjusting the position of the slider to facilitate its alignment with the docking hole on the can cage. Then, the bolt is taken out, passed through the mounting hole on the surface of the slider, and connected to the docking hole of the can cage. At this time, the protruding part of the bolt fits against the annular block, and the sealing ring can form a seal at the connection between the protruding part of the bolt and the annular block, thereby preventing dust from entering the gap and preventing subsequent disassembly and assembly difficulties due to dust accumulation.

[0016] 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.

[0017] Please see Figures 1-5 The present invention provides the following technical solution: a roller can ear with a lubrication mechanism, including a mounting base 1, a support block 2 connected to the top surface of the mounting base 1, a fixing plate 3 rotatably connected to the top of the support block 2, a roller 4 rotatably connected inside the fixing plate 3, an adjusting oil cylinder 5 rotatably connected to the top of the mounting base 1, a storage box 6 connected to the back end of the support block 2, an oil inlet pipe 7 installed on the outer wall of the storage box 6, a groove 8 penetrating through the inner wall of the storage box 6, a filter plate 9 installed inside the groove 8, a sealing baffle 10 inserted inside the filter plate 9, a threaded rod 11 threadedly connected to the top of the storage box 6, and an oil inlet groove 15 opened on the surface of the support block 2.

[0018] In practical use, the roller can ear consists of a mounting base 1, a support block 2, a fixing plate 3, rollers 4, and an adjusting cylinder 5. In actual use, the roller can ear is installed on the cage, and then the roller can ear runs along the rectangular steel can track. The friction between the rollers 4 and the can track guides the container, keeping the lifting container stable during vertical movement and reducing swaying and deviation. When the lifting container is impacted, the adjusting cylinder 5 absorbs the impact energy and transmits the force to the shock absorber through the lever mechanism, playing a buffering and stabilizing role.

[0019] Preferably, the filter plate 9 and the sealing baffle 10 are sealed together. The end of the threaded rod 11 is rotatably connected inside the sealing baffle 10. The oil inlet groove 15 has the same dimensions as the groove 8.

[0020] In practical use, the filter plate 9 and the sealing baffle 10 are sealed together. The operator injects lubricating oil into the storage box 6 through the oil inlet pipe 7, thus forming a seal inside the storage box 6 to store the lubricating oil. This also prevents the lubricating oil from seeping into the oil inlet groove 15 through gaps. At the same time, the sealing baffle 10 is T-shaped, and the inner wall of the storage box 6 has an opening for the sealing baffle 10 to move. The protruding part of the sealing baffle 10 extends into the opening in the inner wall of the storage box 6. In this way, when the rotating threaded rod 11 starts to move, the sealing baffle 10 will not rotate with the threaded rod 11. The oil inlet groove 15 and the groove 8 are the same size, which facilitates the flow of lubricating oil. At the same time, the connection between the storage box 6 and the support block 2 is sealed to prevent leakage of lubricating oil during flow.

[0021] Preferably, the surface of the mounting base 1 has a groove 16, and a slider 12 is slidably connected inside the groove 16. An annular block 13 is connected to the top of the slider 12, and a sealing ring 14 is installed on the inner wall of the annular block 13. The groove 16 and the slider 12 are fitted together in a cross shape. The inner ring of the sealing ring 14 has the same size as the mounting hole on the surface of the slider 12.

[0022] In practical use, the slide groove 16 and the slider 12 are matched in a "+" shape, and the slider 12 will not detach from the slide groove 16. At the same time, the surface of the slider 12 is provided with a through mounting hole. Then, the inner ring of the sealing ring 14 is the same size as the mounting hole on the surface of the slider 12. This will not affect the connection of the bolt, and the sealing ring 14 can also ensure the sealing performance.

[0023] Working principle: The operator first installs the roller can ear on the can cage, and then pushes the slider 12 to slide along the slide groove 16 to adjust the position of the slider 12 so that it is aligned with the docking hole on the can cage. Then, the bolt is taken out, passed through the mounting hole on the surface of the slider 12 and connected to the docking hole of the can cage. At this time, the protruding part of the bolt fits against the annular block 13, and the sealing ring 14 will form a seal at the connection between the protruding part of the bolt and the annular block 13, thereby preventing dust from entering the gap and preventing subsequent disassembly and assembly difficulties due to dust accumulation. Then, the roller can ear is used. At this time, the roller can ear runs along the rectangular steel can track. The container is guided by the friction between the roller 4 and the can track, ensuring that the lifting container remains stable during vertical movement and reducing shaking and deviation. When the lifting container is impacted, the adjusting cylinder 5 will absorb the impact energy and transmit the force to the shock absorber through levers and other mechanisms, playing a buffering and stabilizing role. Next, if the pin is to be lubricated, the operator injects lubricating oil into the storage box 6 through the oil inlet pipe 7, and then rotates the threaded rod 11 to make it drive the sealing baffle 10 to rise synchronously. After the sealing baffle 10 rises, the mesh opening of the filter plate 9 is exposed. The lubricating oil in the storage box 6 passes through the filter plate 9 and is guided through the groove 8 to the oil inlet groove 15, and then transported along the oil inlet groove 15 to the inside of the support block 2, making full contact with the pin inserted on the support block 2, thus achieving full lubrication of the pin. This avoids the problem of insufficient lubrication caused by the grease not being able to cover the entire pin when lubricating oil is added from both ends of the pin in the traditional way. This significantly reduces the wear of the pin caused by insufficient lubrication and greatly extends the overall service life of the roller can ear.

[0024] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
