Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoist component technology, specifically to a rubber-coated tile component for reducing friction in a hoist. Background Technology
[0002] In the operating system of a winding hoist, the drum, as the core component for transmitting power and winding the wire rope, directly affects the wear and tear and operational safety of the equipment due to the contact state between its surface and the wire rope. To address the problems of high frictional wear and short component life caused by the hard contact between the traditional metal drum and the wire rope, the industry commonly uses rubber-coated tiles on the outer circumference of the drum. The elastic buffering properties and low coefficient of friction of the rubber material on the surface of the rubber-coated tiles replace the direct contact between the metal surface and the wire rope, thereby effectively reducing frictional wear between the two, reducing the risk of wire rope breakage, drum corrosion and other failures, and extending the equipment maintenance cycle.
[0003] However, in practical applications, the connection between existing rubber-coated roofing sheets and the drum is mostly a fixed structure, making the disassembly and assembly process extremely cumbersome. This is especially true in scenarios with large drum diameters or high-altitude operations, where the disassembly and assembly process is tedious and laborious, significantly increasing maintenance time and costs. In addition, since the drum surface is usually quite smooth, and the contact surface between the rubber-coated sheets and the drum lacks an effective anti-slip structure, during the operation of the hoist, when affected by factors such as the winding tension of the wire rope, equipment vibration, or load changes, relative slippage can easily occur between the rubber-coated sheets and the drum, i.e., slippage occurs.
[0004] To address this, a rubber-coated tile assembly for reducing friction in a hoisting machine is proposed. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rubber-coated tile assembly for reducing friction in a hoist, so as to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution.
[0007] This utility model provides a rubber-coated tile assembly for reducing friction in a hoist, comprising two symmetrically arranged arc-shaped tiles, each of which has a rubber coating on its outer side wall, and a fixing mechanism on the side of each of the two arc-shaped tiles that is close to each other.
[0008] The fixing mechanism includes fixing rings fixedly disposed on the side walls of the two arc-shaped tiles, and fixing bolts and fixing nuts that cooperate with each other are provided between two adjacent fixing rings;
[0009] Both ends of the two arc-shaped tiles are fixed with arc-shaped mounting pieces, and the sidewalls of the arc-shaped mounting pieces are provided with multiple evenly distributed mounting holes.
[0010] Preferably, the surface of the rubber coating layer is provided with a plurality of uniformly distributed strip-shaped anti-slip grooves.
[0011] Preferably, each of the two curved tiles has a mounting groove at both ends, and the fixing mechanism is located inside the two adjacent mounting grooves.
[0012] Preferably, the two arc-shaped tiles are joined together to form a circular tube shape, and the two arc-shaped tiles are wrapped around the wall of the roll.
[0013] Preferably, the arc-shaped mounting plate is fixedly connected to the retaining rings on both sides of the drum through mounting holes.
[0014] Preferably, the arc-shaped tile is made of arc-shaped bent steel plate, and the arc-shaped mounting piece is fixedly welded to the arc-shaped tile.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This component achieves convenient assembly and disassembly through a fixing mechanism and an arc-shaped mounting plate: adjacent fixing rings in the fixing mechanism are connected by fixing bolts and fixing nuts, which can quickly complete the splicing and disassembly of two arc-shaped tiles; the arc-shaped mounting plate is fixed to the retaining rings on both sides of the drum through mounting holes. During assembly and disassembly, only the corresponding connecting parts need to be operated, without complicated procedures, which greatly simplifies the loading and unloading process on the drum surface and reduces maintenance time and difficulty.
[0017] 2. This component solves the problem through multiple structural synergies: two arc-shaped tiles are spliced together to form a cylindrical shape that tightly wraps around the drum wall, and with the fastening effect of the fixing mechanism, it ensures that the tiles and the drum are tightly fitted; the fixed connection between the arc-shaped mounting plate and the drum retaining ring further restricts the axial displacement of the component; at the same time, the strip-shaped anti-slip grooves on the surface of the rubber coating enhance the meshing effect with the wire rope, reducing the possibility of the wire rope causing the arc-shaped tiles to slide, thereby effectively avoiding relative sliding between the rubber-coated tiles and the drum and improving operational stability.

[0023] A rubber-coated tile assembly for reducing friction in a hoist, such as Figure 1-4 As shown, the device includes two symmetrically arranged arc-shaped tiles 1, which are joined together to form a cylindrical shape. The two arc-shaped tiles 1 are wrapped around the wall of the drum. The outer walls of the two arc-shaped tiles 1 are provided with a rubber coating layer 2. The surface of the rubber coating layer 2 is provided with multiple evenly distributed strip-shaped anti-slip grooves 6, which can enhance the friction between the tile and the wire rope and effectively prevent the wire rope from sliding relative to the tile surface during the operation of the hoist. The two ends of the two arc-shaped tiles 1 are provided with a fixing mechanism 3 on the side closest to each other. The two ends of the two arc-shaped tiles 1 are provided with a mounting groove 34. The fixing mechanism 3 is located inside the two adjacent mounting grooves 34, which can prevent the fixing mechanism 3 from protruding outward and being installed on the outside of the arc-shaped tiles 1, thus avoiding installation obstruction. The fixing mechanism 3 includes a fixing ring 31 fixedly set on the side wall of the two arc-shaped tiles 1. The two adjacent fixing rings 31 are provided with a fixing bolt 32 and a fixing nut 33 that cooperate with each other.
[0024] Both ends of the two curved tiles 1 are fixed with curved mounting plates 4. The curved tiles 1 are made of curved bent steel plates. The curved mounting plates 4 are fixedly welded to the curved tiles 1. The side walls of the curved mounting plates 4 are provided with multiple evenly distributed mounting holes 5. The curved mounting plates 4 are fixedly connected to the retaining rings on both sides of the drum through the mounting holes 5. The inside of the mounting holes 5 is used to insert connectors to connect the curved mounting plates 4 and the drum as one unit, so as to avoid relative rotation between the curved mounting plates 4 and the drum.
[0025] In summary: The component uses two arc-shaped tiles 1 as the main structure. After splicing, the two form a cylindrical shape that fits the drum and tightly wraps around the drum wall to achieve full coverage of the drum surface. The rubber coating layer 2 set on the outer wall of the arc-shaped tile 1 is in direct contact with the wound steel wire rope. With the help of the elastic buffer properties and low friction coefficient of the rubber material, it replaces the traditional metal-to-metal contact, which greatly reduces the friction and wear between the steel wire rope and the drum, and reduces the risk of steel wire rope breakage and drum corrosion.
[0026] To address the issue of slippage between existing rubber-coated roofing sheets and steel wire ropes, the surface of the rubber coating layer 2 is designed with multiple evenly distributed strip-shaped anti-slip grooves 6. By increasing the mechanical meshing of the contact surfaces, the friction between the steel wire rope and the roofing sheet is enhanced, effectively preventing relative slippage of the steel wire rope on the roofing sheet surface during hoist operation and ensuring the stability of the steel wire rope winding.
[0027] In terms of fixing and disassembly, the component solves the problems of inconvenience in disassembling and disassembling traditional coated tiles and easy slippage with the roller through a dual-structure design: On the one hand, a fixing mechanism 3 is provided on the side of the two curved tiles 1 that are close to each other. The fixing ring 31 on the side wall of the adjacent curved tile 1 is fastened by the fixing bolt 32 and the fixing nut 33, so that the two curved tiles are spliced tightly to form an integral structure; on the other hand, the curved mounting pieces 4 fixed on the outer side walls of the two ends of the curved tile 1 are fixedly connected to the retaining rings on both sides of the roller through multiple mounting holes 5 on their side walls, further securing the entire component on the roller and preventing relative slippage between the component and the roller. When maintenance or replacement is required, simply loosen the fixing bolt 32, the fixing nut 33 and the connecting piece between the curved mounting piece 4 and the retaining ring, and the two curved tiles 1 can be easily removed from the roller, simplifying the disassembly and assembly process and reducing maintenance difficulty and cost.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
