AI Technical Summary
In high-speed EMUs, the assembly of the brake hose requires repeated removal of the table vise multiple times, resulting in wasted time, and the extrusion of the table vise jaw causes scratches on the tube interface surface.
Design a quick connection device for brake hose, adopting a plate-like structure, with a square lower part and a semicircular upper part. Hexagonal studs installed on the semicircular drilling hole, and tightening with an electronic torque wrench to reduce the frequency of use of the table vise and pressure on the interface.
The quick connection of the brake hose is achieved, avoiding scratches on the tube interface surface, significantly reducing assembly time and improving the durability of the interface.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of undercarriage equipment of rail vehicles, and in particular relates to a quick connection device for brake hoses. Background Art
[0002] The bogie is the running part of the EMU, and the brake system is the most important system to ensure the safe operation of the high-speed EMU. The success or failure of the assembly of the brake hose determines whether the brake system can operate successfully. The brake hose of the high-speed EMU is divided into two types: 4-branch and 2-branch. The operator needs to rotate the handle to open the bench vise, put the pipe on the bench vise and then lock it. Repeated disassembly wastes a lot of time. In addition, during the assembly of the brake hose, the frequent use of the bench vise mouth to squeeze the pipe interface surface causes scratches, which ensures product quality. Utility Model Content
[0003] The utility model aims to solve the problem that when assembling the brake hose, the pipeline needs to be repeatedly disassembled on the bench vise, which wastes a lot of time and the surface of the pipe interface is scratched by squeezing the bench vise mouth, thereby providing a brake hose quick connection device, which is easy to connect and will not cause scratches on the surface of the pipe interface
[0004] To achieve the above-mentioned purpose of the utility model, the utility model provides a brake hose quick connection device, which is plate-shaped as a whole, with a square lower part and a semicircular upper part. A hole is drilled on the semicircle, and a hexagonal stud matching the brake hose connector is installed in the hole.
[0005] Furthermore, the brake hose joint is a 4-branch joint and a 2-branch joint, and two holes with diameters of Φ32 and Φ19 are drilled on the semicircle, and hexagonal studs matching the 4-branch joint and the 2-branch joint are respectively installed in the holes.
[0006] The utility model fixes a hexagonal stud matched with a brake hose joint on a plate with a square lower portion and a semicircular upper portion, the lower square portion is clamped on a bench vise, one end of the brake hose joint is threadedly connected to the brake hose, and the other end is placed in the hexagonal stud of the device, and an electronic torque wrench is used to tighten it according to the designed torque, effectively reducing the process of opening and closing the bench vise during the installation of the pipeline interface, and avoiding the deformation of the bench vise mouth on the pipeline joint due to stress. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a schematic diagram of the structure of the utility model;
[0008] Figure 2 This is a schematic diagram of the brake hose connector;
[0009] Figure 3 This is a schematic diagram of the connection between the brake hose quick connect device and the brake hose connector. DETAILED DESCRIPTION
[0010] In order to better understand the purpose, structure and function of the utility model, a brake hose quick connection device of the utility model is further described in detail below with reference to the accompanying drawings.
[0011] Reference Figure 1 The brake hose quick connection device is plate-shaped as a whole, with a square lower part and a semicircular upper part. Two holes of Φ32 and Φ19 are drilled on the semicircle. The 4-branch pipe joint and the 2-branch pipe joint matching hexagonal studs are installed in the holes respectively and fixed by welding.
[0012] When in use, clamp the lower square part of the device on the bench vise, and tighten the bench vise to clamp the device. Connect one end of the 4-way or 2-way pipe joint to the brake hose thread, put the other end of the pipe joint into the hexagonal stud of the device, and use an electronic torque wrench to tighten it according to the designed torque. Since the pipeline interface matches the hole of the device, the pressure of the bench vise mouth can avoid damage to the pipeline interface; and reduce the process of opening and closing the bench vise during the replacement of the pipeline.
