Description

Technical Field

[0001] This utility model belongs to the technical field of cable anti-wear protection devices, and specifically relates to a cable anti-wear protection device. Background Technology

[0002] In suspended operations in construction and other fields, cables are commonly used to support suspended platforms, tools, materials, and safety harnesses for workers, serving to support and lift these items. The primary function of cables is to bear heavy loads, enabling them to be raised, lowered, or suspended at the required position for construction, maintenance, cleaning, and other lifting operations.

[0003] In practical applications, cables often need to pass over sharp points on rooftops or special terrain features, such as protruding corners of walls, door and window openings, etc. Cables used at sharp points are subjected to cutting and scraping, which can easily lead to damage, wear, and even breakage over time. This poses certain safety hazards, not only affecting work efficiency but also potentially causing accidents.

[0004] There are two existing methods for handling this issue: The first is to add protective sleeves or sheaths. These specially designed sleeves or sheaths are added to the sharp points of the cable to reduce friction and wear, and improve abrasion resistance. This method can protect the cable from damage by sharp surfaces to some extent, but it is complex and costly. The second method is to change the angle or path of the cable. By adjusting the angle or path of the cable, the angle change is minimized when it passes over sharp points, reducing friction and wear. This method can reduce the degree of wear, but it is not suitable for all situations.

[0005] Therefore, in order to solve the problem of cable breakage at sharp points, a special device needs to be designed to reduce friction and wear, extend the service life of the cable, and improve work safety. Utility Model Content

[0008] Furthermore, in the bracket, the parallel front plate and the rear plate are respectively fixed to the base plate, forming a double-layer structure for mounting the rollers.

[0009] Further, the front plate and the rear plate are both provided with outwardly expanded corner inclined plates.

[0010] Further, the outer end of the corner inclined plate is provided with a corner end plate, and the roller and the anti-falling piece are both mounted on the corner end plate.

[0024] In order to facilitate the understanding of the utility model, the utility model will be described in more detail below in conjunction with the drawings and specific embodiments. However, the utility model can be realized in many different forms and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of the utility model more thorough and comprehensive.

[0025] In order to better understand and describe, the cable and external corner are described: the external corner refers to the wall corner protruding on the wall surface, such as the four corners protruding on the outside of the building and the included angle between the door and window hole and the wall surface. The cable is composed of multiple filaments and is used for hoisting, traction or tethering purposes; it is usually made of metal wire, plastic wire or natural fiber and has certain tensile and wear-resistant properties. When the cable directly contacts the external corner, the wear is aggravated.

[0026] Embodiment 1: in conjunction with Figures 1-3 It is understood that a cable wear-preventing protection device comprises: a bracket 4, which is a double-layer structure symmetrically shaped like a horn; a roller 1, which is rotatably installed on the horn end of the bracket 4 in a suspended manner through a mounting shaft 5; a fixing member, which is symmetrically installed on the bracket 4 and located on the side away from the roller 1; and an anti-falling member, which is installed on the bracket 4 in a suspended manner and located on the outside of the roller 1.

[0027] Among them, the bracket 4 can be made of steel or carbon fiber and other high-strength materials and is an integral structure for fixing other components. The roller 1 is made of wear-resistant plastic or alloy material, and the distance and arrangement angle between the rollers can be accurately designed according to actual use. The anti-falling member can be made of corrosion-resistant and wear-resistant metal materials such as stainless steel or aluminum alloy to prevent the cable from falling out of the device.

[0028] In addition to the traditional expansion bolt fixing, the fixing mode between the bracket 4 and the structure can also be pre-buried, welded, bolted, steel structure plug-in connected, pull rod connected and other fixing connection modes. Specifically, the fixing member is used for the connection and fixing of the bracket 4 and the structure, and the fixing member can be an expansion bolt, which is convenient for flexible installation and suitable for multiple scenes; it can also be a pre-buried pull rod, which is fixed by tension and suitable for situations that need to bear large tension; it can also be fixed on the structure by using a bolt and a nut, which is convenient for disassembly and installation and suitable for situations that need to be frequently replaced or adjusted; it can also be inserted into the steel structure member to realize fixed connection, which is suitable for complex steel structure scenes.
