Description

Technical Field

[0001] This utility model belongs to the technical field of roller can ear, specifically relating to roller can ear with good heat dissipation effect. Background Technology

[0002] Roller lugs are an important piece of equipment used in vertical shaft hoisting containers. Installed on the hoisting container, the rollers are in direct contact with the steel guide rails and bear the horizontal forces generated during the container's operation. As the hoisting container moves along the guide rails, joints and bends occur due to the design and installation of the guide rails, causing the roller heads to experience horizontal thrust. Through the hinged connection between the boom, base, and buffer, the buffer is compressed, generating a rebound force. This rebound force ensures the hoisting container smoothly passes through high points, avoids collisions with the guide rails, and controls the swing amplitude of the hoisting container within a certain range during ascent and descent.

[0003] The roller can ear mainly consists of a base, a swing arm, rollers, and a buffer. Some roller can ears use a disc spring assembly for buffering. The spring buffer assembly consists of an adjusting sleeve, adjusting screw, nut, disc spring shaft, guide sleeve, cap, set screw, disc spring, key, and cylinder.

[0004] During continuous high-frequency operation in vertical shaft hoisting systems, the combined effects of frictional heat generated between the wheel hub and bearing, as well as environmental heat conduction, cause a significant accumulation of heat on the wheel hub surface. Actual measurements show that after two hours of continuous operation, the wheel hub temperature can reach over 85°C, exceeding the allowable temperature threshold (70-80°C) for aluminum alloy materials. This high temperature not only accelerates fatigue aging of the wheel hub material, causing metal lattice distortion and resulting in decreased strength, but also leads to grease dilution and loss—when the temperature rises to 90°C, the viscosity of lithium-based grease decreases by more than 50%, causing the bearing to enter a boundary lubrication state and exacerbating wear. Simultaneously, heat conduction to the rubber wheel causes material softening, reducing its Shore hardness by 15-20 HA, resulting in an increase in contact deformation of 2-3 mm. This leads to uncontrolled clearance between the wheel hub and the hoisting channel, causing the lateral sway of the hoisting container to exceed the ±10 mm safety threshold, and in severe cases, even causing a canister jamming accident. Utility Model Content

[0005] The purpose of this invention is to provide a roller can ear with good heat dissipation, aiming to solve the problem in the prior art where, during continuous high-frequency operation in a vertical shaft hoisting system, the roller can ear experiences a large accumulation of heat on the surface of the hub due to the combined effects of frictional heat generation between the hub and bearing and environmental heat conduction. Actual measurements show that after two hours of continuous operation, the hub temperature can reach over 85℃. This high temperature not only accelerates the fatigue aging of the hub material and causes metal lattice distortion leading to a decrease in strength, but also causes grease dilution and loss, resulting in the bearing entering a boundary lubrication state and exacerbating wear. Simultaneously, heat conduction to the rubber wheel causes material softening, reducing its Shore hardness by 15-20 HA, resulting in an increase in contact deformation of 2-3 mm. This leads to uncontrolled clearance between the can ear and the can guideway, causing the lateral sway of the hoisting container to exceed the standard (above the ±10 mm safety threshold), and in severe cases, even causing can jamming accidents.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a roller can ear with good heat dissipation effect, including a mounting plate and a connecting seat mounted on the bottom surface of the mounting plate, a side plate movably connected to the side of the connecting seat, a wheel hub installed inside the side plate, a polyurethane wheel connected to the surface of the wheel hub, a connecting plate connected to one side of the side plate, and a buffer cylinder connected to the inner side of the connecting plate.

[0009] As a preferred embodiment of the present invention, the roller can ear with good heat dissipation effect is provided, wherein the heat dissipation fin is semi-circular, and both the heat dissipation fin and the heat dissipation fin are made of stainless steel.

[0010] As a preferred embodiment of the present invention, the heat dissipation fins are provided with a docking groove on the side near the docking block, and the two heat dissipation fins are engaged with the docking block through the docking groove.

[0011] As a preferred embodiment of the present invention, the roller can ear with good heat dissipation effect is provided with two sets of heat dissipation fins, and the two sets of heat dissipation fins are symmetrically arranged about the longitudinal central axis of the hub.

[0012] As a preferred embodiment of the present invention, the roller can ear with good heat dissipation effect is provided with a threaded hole on the side of the docking block near the locking screw, and the locking screw passes through the card plate and is threadedly connected to the threaded hole on one side of the docking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention involves installing two sets of heat dissipation fins on the side of the wheel hub, then aligning the mating grooves at the mating ends of the two heat dissipation fins with the mating block, and finally threading the locking screw through the clamping plate to the mating block. This facilitates the installation of the heat dissipation fins on the side of the wheel hub. At this time, the heat dissipation fins on the surface of the heat dissipation fins quickly dissipate the heat accumulated on the surface of the wheel hub in the wheel can ear, thereby improving the service life of the wheel can ear.

A side plate 3 is movably connected to the side of the connecting seat 2. A hub 4 is installed inside the side plate 3. A polyurethane wheel 5 is connected to the surface of the hub 4. A receiving plate 6 is connected to one side of the side plate 3. A buffer cylinder 7 is connected to the inner side of the receiving plate 6.

[0024] A mating block 8 is connected to the side of the hub 4. A heat dissipation fin 9 is connected to the side of the hub 4 near the mating block 8. A heat dissipation fin 10 is connected to one side of the heat dissipation fin 9. A retaining plate 11 is connected to the side of the heat dissipation fin 10 near the mating block 8. A locking screw 12 is connected through the surface of the retaining plate 11.

[0025] Preferably, the connecting plate 6 is rotatably connected to one end of the buffer cylinder 7, and the other end of the buffer cylinder 7 is rotatably connected to the bottom surface of the mounting plate 1.

[0026] In practical use, the buffer cylinder 7 is generally composed of a cylinder barrel, piston, piston rod, buffer spring, and sealing components. When the roller can ear is impacted by an external force, such as when encountering vibration or collision during the lifting and lowering of the cage, the piston rod in the buffer cylinder 7 will drive the piston to move inside the cylinder barrel. At this time, the hydraulic oil in one side chamber of the piston is compressed and slowly flows to the other side chamber through the throttling orifice or other damping device. Due to the viscous resistance and throttling effect of the hydraulic oil, a damping force is generated, thereby slowing down the movement speed of the piston rod and playing the role of buffering the impact force. At the same time, the buffer spring is also compressed, absorbing some of the impact energy and further enhancing the buffering effect.

[0027] Preferably, the heat dissipation fin 9 is semi-circular, and both the heat dissipation fin 9 and the heat dissipation fin 10 are made of stainless steel.

[0028] In practical use, the heat dissipation fins 10 on the surface of the heat dissipation fin plate 9 facilitate the dissipation of heat accumulated on the surface of the wheel hub 4, thereby increasing the surface area for heat dissipation of the wheel hub 4 and improving the heat dissipation effect.

[0029] Preferably, a docking groove is provided on the side of the heat dissipation fin 9 near the docking block 8, and the two heat dissipation fins 9 are engaged with the docking block 8 through the docking groove.

[0030] In practical use, the mating groove at the mating end of the heat dissipation fin 9 is connected to the mating block 8, thereby facilitating the quick and stable assembly of the heat dissipation fin 9.

[0031] Preferably, the heat dissipation fins 9 are provided in two sets, and the two sets of heat dissipation fins 9 are symmetrically arranged about the longitudinal central axis of the hub 4.

[0032] In practical use, the use of two sets of heat dissipation fins 9 makes it easy to install and stabilize the heat dissipation fins 10 on the surface of the heat dissipation fins 9.

[0033] Preferably, the mating block 8 has a threaded hole 13 on the side near the locking screw 12, and the locking screw 12 passes through the retaining plate 11 and is threadedly connected to the threaded hole 13 on the side of the mating block 8.

[0034] In practical use, the locking screw 12 is threaded through the card plate 11 and connected to the mating block 8, which facilitates the stable installation of the two heat dissipation fins 9.

[0035] The working principle of this utility model in specific use is as follows: First, two sets of heat dissipation fins 9 are installed on the side of the hub 4. Then, the mating grooves of the mating ends of the two heat dissipation fins 9 are mated with the mating block 8. Then, the locking screw 12 is threaded through the clamping plate 11 and connected to the mating block 8, which facilitates the installation of the heat dissipation fins 9 on the side of the hub 4. At this time, the heat dissipation fins 10 on the surface of the heat dissipation fins 9 quickly dissipate the heat accumulated on the surface of the hub 4 in the roller can ear, avoid the accumulation of a large amount of heat on the surface of the roller can ear, and improve the service life of the roller can ear.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
