Description
Technical Field
The invention relates to the technical field of cargo transportation safety, in particular to a member for wear prevention, which meets railway transportation safety requirements.
Background
When the goods on the railway or highway are loaded and transported, the contact between the reinforcing line and the goods and the corner angle of the vehicle should take anti-wear measures. The abrasion-proof measure is that a rubber pad is adopted to be placed at the contact position of the traction reinforcing material and the corner of the goods and the vehicles. The patent No. 200920304818.7 discloses a rubber wear-resistant pad for cargo transportation and loading reinforcement, which is divided into n, C, L and other types according to the applicable position and shape, and is essentially a wear-resistant pad with a planar configuration which adapts to the surface shape of the applicable position through shape change. The rubber anti-wear pad with the structure can be suitable for traction binding materials with various diameters such as steel wire ropes, but in actual use, due to the effects of vibration and the like, anti-falling wings at two sides of the rubber anti-wear pad fail, so that n-shaped and L-shaped rubber anti-wear pads are loosened in the railway transportation process, anti-wear measures fail, and the traction binding materials are in direct contact with goods and vehicles at edges.
Disclosure of Invention
The invention aims to solve the problem of providing an anti-wear structure for avoiding loosening and failure of anti-wear measures in the transportation process. The technical scheme is as follows:
the inner wall of the sleeve body is provided with limiting ribs, and a channel is formed by grooves between the two limiting ribs; extension structures are arranged at two ends of the sleeve body. The lengthening structure is characterized in that a first protruding falcon is arranged at one port of the sleeve body, a falcon groove is respectively arranged on the pipe walls at two sides of the first protruding falcon, a notch is arranged at the other port of the sleeve body, and a second protruding falcon is respectively arranged at two sides of the notch.
The second protruding falcon is provided with a buckle, and the falcon groove is provided with a clamping groove.
Radial anti-slip strips are arranged on one side of the outer wall of the sleeve body.
And a wall on one side of the sleeve body is provided with an alignment observation hole.
And an alignment mark is arranged on the outer wall of the other side of the sleeve body.
The limiting convex ribs are uniformly distributed in the sleeve body along the circumferential direction.
Compared with the prior art, the invention has the following beneficial effects:
1. the anti-wear sleeve is of a tubular structure, and the mode of wrapping the traction binding material in a partially encircling manner can be adopted to adapt to the traction angle change of the traction binding material and the shape of the tie-down point, so that the anti-wear liner with a common plane configuration is effectively prevented from loosening under the actions of vibration and the like in the railway transportation process, and the anti-wear measure is invalid. The method not only meets the requirement of railway transportation that the contact position of the reinforcing line and the corner of the goods and the vehicles should take anti-wear measures, but also realizes the unification of the applicability of the anti-wear sleeve to different shapes of a plurality of positions where the anti-wear measures should be taken.
2. Limiting ribs on the inner wall of the wear-resistant sleeve are used for limiting the traction binding materials such as steel wire ropes at grooves among the limiting ribs, so that the resistance of the wear-resistant sleeve to axial rotation (turnover) of the traction binding materials is increased; meanwhile, the elastic cambered surface formed by the cooperation of the limiting convex ribs and the grooves increases the contact area of the anti-abrasion sleeve at the corner contact position and the tying point of the goods or (railway) vehicles and the traction binding material, so that the anti-abrasion sleeve is fully attached to the outer surface of the traction binding material to play a role in abrasion resistance, and the buffer effect of the rubber material is utilized to slow down the bending change degree of the traction binding material at the position and effectively reduce the shearing stress formed in the traction binding material at the position.
3. The anti-wear sleeve is provided with radial anti-slip strips on the outer wall, which are used for increasing the resistance of the anti-wear sleeve on the surfaces of objects such as goods or (railway) vehicles and the like along the axial sliding direction of the traction binding material, and the radial anti-slip strips on the outer wall and the limit ribs on the inner wall act together under the pressure of the traction binding material to fix the anti-wear sleeve at a proper position so as to prevent the traction binding material from being in direct contact with the goods or (railway) vehicles (corner contact positions and the like).
4. The anti-wear sleeve is provided with the anti-wear sleeve, and the anti-wear sleeve is provided with the anti-wear sleeve, wherein the anti-wear sleeve is provided with the anti-wear sleeve, and the anti-wear sleeve is provided with the anti-wear sleeve; secondly, the wear-resistant sleeve is in a bending state at the contact position of the steel wire rope and other traction binding materials and edges and corners of goods or (railway) vehicles, and is used as a telescopic hole of a limiting convex rib, so that the concentration of shearing stress is prevented, and the service life of the wear-resistant sleeve is prolonged.
5. The buckles at the two ends of the anti-wear sleeve are clamped into the clamping grooves at the corresponding positions to form 'occlusion', so that the anti-wear sleeve is connected in series and prolonged.
