[0019] Figure 1 It is a schematic diagram of the overall three-dimensional structure of a railway vehicle wire stripping and wind ring replacement device according to the utility model;

[0020] In the figure: a first steel pipe 1; a second steel pipe 2; a chamfer 3; and a flat head 4. DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0022] This embodiment discloses a railway vehicle wire stripping and wind ring replacement device, combined with Figure 1As shown, a railway vehicle wire stripping and wind ring replacement device comprises a first steel pipe 1 and a second steel pipe 2, wherein the first steel pipe 1 and the second steel pipe 2 are fixedly connected, and the first steel pipe 1 and the second steel pipe 2 are connected to form a "T" shape, which is convenient for operators to spirally twist the bundled wires, and one end of the first steel pipe 1 is installed in the middle of the second steel pipe 2. The first steel pipe 1 and the second steel pipe 2 are connected by welding, preferably argon arc welding, which has the following advantages: 1. High weld quality: The welding quality of argon arc welding is very good, and the weld is uniform and free of 1. The weld has strong mechanical properties, such as pores and cracks; 2. Small thermal deformation: When argon arc welding is carried out under argon protection, the deformation of the welding material under high temperature can be guaranteed to be small, thereby avoiding the problem of welding deformation; 3. Beautiful forming: The appearance of argon arc welding after welding is beautiful, which is conducive to the sales and use of the product; 4. A wide range of welding materials: argon arc welding can weld a variety of different materials of metal, such as aluminum, copper, magnesium, tin, zinc, etc.; 5. The strength of the welded joint is high: because the weld of argon arc welding is uniform and of good quality, the welded joint has the advantage of high strength. The end of the first steel pipe 1 away from the second steel pipe 2 is provided with a chamfer 3, and the chamfer 3 is 30° to 60°. The first steel pipe 1 is a hollow structure, and a thread is provided in the hole at the end of the first steel pipe 1 away from the second steel pipe 2. The threaded hole of the first steel pipe 1 can be used to connect an external connecting arm when needed, thereby achieving the effect of increasing the force arm, while saving effort, increasing the operating space, and avoiding the phenomenon that the operator is inconvenient to use force in a narrow space. The chamfer 3 can facilitate the wire to pass into the bottom hole. The material of the first steel pipe 1 and the second steel pipe 2 is white steel, which has the advantages of high hardness, wear resistance, corrosion resistance, light weight, harmlessness, long life and good performance-price ratio:

[0023] High hardness and wear resistance: White steel has high hardness and wear resistance after heat treatment, which makes it very suitable for manufacturing tools and parts such as knives, molds, and measuring tools that require high hardness and wear resistance.

[0024] Corrosion resistance: Stainless steel has good corrosion resistance and can resist corrosion from alkaline solutions and most organic and inorganic acids, especially from carbon compounds and chlorine compounds.

[0025] Lightweight: Stainless steel guardrails are lightweight because they are usually hollow inside, which makes them much lighter than wrought iron guardrails and easier to carry and install.

[0026] Harmlessness: Stainless steel is harmless to humans and animals and will not cause harm. It is suitable for use in situations where high safety standards are required.

[0027] Long life: Stainless steel products have a long service life, especially stainless steel guardrails, which can have a service life of more than 100 years without fading, yellowing, peeling, decaying or cracking.

[0028] Good performance-price ratio: The life of white steel bars is more than twice that of ordinary high-speed steel, which can improve the production efficiency of machine tools by more than 2 times. Its comprehensive performance reaches the level of cobalt-containing high-speed steel M42, and it has a very good performance-price ratio.

[0029] The second steel pipe 2 is a solid structure, and one end of the second steel pipe 2 is a flat head 4. The flat head 4 can replace a flat screwdriver. The flat head 4 can be used to pry up the wind ring to quickly remove the damaged wind ring and replace a new wind ring. The other end of the second steel pipe 2 is a hammer head. When in use, the hammer head end can be used to replace the hammer. Since the second steel pipe 2 is a solid structure, the strength of the second steel pipe 2 at the hammer head end can be guaranteed, and the tools required to be carried during the operation can be reduced. When in use, the thin end of the flat head 4 can be inserted into the wire ring or wind ring, and then the wire ring or wind ring can be pried by rotating. During the prying process, the hammer head end is used as a fulcrum, and the overall lever principle is adopted, which can make the operation more labor-saving. A buffer sleeve is mounted on the first steel pipe 1. The buffer sleeve can be made of rubber or sponge material. The relatively soft characteristics of rubber and sponge can improve the comfort of the operator while increasing the friction of the device to avoid slipping during hammering or prying, which poses a threat to personal safety.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
