Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic pipe technology, specifically to a flame-retardant and wear-resistant rubber hydraulic pipe. Background Technology
[0002] Hydraulic hoses, also known as hydraulic oil hoses, hydraulic flexible hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure hoses, and steel wire braided hoses, are generally divided into steel wire braided hydraulic hoses and steel wire spiral hydraulic hoses. Hydraulic hoses mainly consist of a liquid-resistant inner rubber layer, a middle rubber layer, 2, 4, or 6 layers of steel wire spiral reinforcement, and an outer rubber layer. The inner rubber layer allows the conveyed medium to withstand pressure and protects the steel wire from corrosion. The outer rubber layer protects the steel wire from damage, and the steel wire layers act as a reinforcing skeleton.
[0003] In existing technologies, some hydraulic hoses are exposed to the outside, which means they may come into contact with and rub against other workpieces during operation. Prolonged contact and friction will accelerate the damage to the outer rubber layer of the hydraulic hose, and in severe cases, it will damage the steel wire winding reinforcement layer. When the steel wire winding reinforcement layer is damaged, the service life of the middle rubber layer and the inner rubber layer will be greatly reduced, thus affecting the service life of the hydraulic hose. Therefore, a flame-retardant and wear-resistant rubber hydraulic hose is needed. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0028] This utility model provides the following technical solution: a flame-retardant and wear-resistant rubber hydraulic hose. During use, 1. the flame-retardant layer set on the outside of the outer rubber layer can improve the flame-retardant performance of the hydraulic hose and improve the safety performance of the hydraulic hose.
[0029] 2. The soft and hard wear-resistant layers can improve the wear resistance of hydraulic pipes, preventing damage caused by contact and friction with other workpieces during operation, thereby extending the service life of hydraulic pipes.
[0030] Figures 1-4 The diagram shown is a structural schematic of the first embodiment of the flame-retardant and wear-resistant rubber hydraulic hose of this utility model. Please refer to [link / reference]. Figures 1-4 The main body of the flame-retardant and wear-resistant rubber hydraulic hose of this embodiment includes a hydraulic hose body 100.
[0031] The hydraulic hose body 100 includes an outer rubber layer 140, a waterproof layer 150 wrapped around the outer rubber layer 140, a flame-retardant layer 160 wrapped around the waterproof layer 150, and a wear-resistant component 200 disposed on the outside of the flame-retardant layer 160. The wear-resistant component 200 includes a soft wear-resistant layer 210 and a hard wear-resistant layer 220, and a connecting steel wire 230 is disposed on the hard wear-resistant layer 220.
[0032] The hydraulic hose body 100 also includes an inner rubber layer 110, a middle rubber layer 120, and a wire-wound reinforcing layer 130. The inner rubber layer 110 is located outside the middle rubber layer 120, and the middle rubber layer 120 is located inside the wire-wound reinforcing layer 130. The wire-wound reinforcing layer 130 is specifically composed of 2-6 layers of wire. An outer rubber layer 140 wraps around the outside of the wire-wound reinforcing layer 130. The inner rubber layer 110 is located at the innermost part of the hydraulic hose body 100, followed by the middle rubber layer 120. The outer layer 120 is a steel wire winding reinforcement layer 130. The inner rubber layer 110 is used to withstand liquid pressure. The middle rubber layer 120 is used to further improve the strength of the inner rubber layer 110 in withstanding liquid pressure. The steel wire winding reinforcement layer 130 is used to improve the strength of the hydraulic pipe. The outer rubber layer 140 is used to protect the steel wire winding reinforcement layer 130 from damage. The waterproof layer 150 and the flame retardant layer 160 are used to improve the waterproof performance and flame retardant performance of the hydraulic pipe, respectively, thereby improving the safety of the hydraulic pipe.
[0033] The soft wear-resistant layer 210 is located on the inner wall of the hard wear-resistant layer 220. The inner wall of the soft wear-resistant layer 210 is bonded to the flame-retardant layer 160. There are multiple hard wear-resistant layers 220, which are evenly distributed on the outside of the flame-retardant layer 160. The multiple hard wear-resistant layers 220 are connected by connecting steel wires 230.
[0034] The wear-resistant component 200 is used to improve the wear resistance of the hydraulic pipe. During use, since the hard wear-resistant layer 220 is located on the outermost side of the hydraulic pipe, when friction occurs, the hard wear-resistant layer 220 replaces the hydraulic pipe in contact with other workpieces, solving the problem of damage caused by long-term friction between the hydraulic pipe and other workpieces. By setting a soft wear-resistant layer 210 on the inner wall of the hard wear-resistant layer 220, it is possible to prevent the hard wear-resistant layer 220 from directly contacting the flame-retardant layer 160, preventing the hard wear-resistant layer 220 from causing wear to the flame retardant layer and affecting the flame-retardant effect of the flame-retardant layer 160. The connecting steel wire 230 is used to connect the two hard wear-resistant layers, thereby realizing the bending function of the wear-resistant component 200.
[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
