Description

Technical Field

[0001] The utility model belongs to the field of special pipeline connection auxiliary devices for rail vehicles, and in particular relates to a tool for butt-jointing and installing brake pipelines of rail vehicles. Background Art

[0002] The rail train braking system is a key system for vehicle operation safety. The brake pipeline includes steel pipes and flexible hoses connected together with joints. Its function is to transfer the brake fluid obtained from the master cylinder to each wheel brake. Pipeline leakage will cause the braking system to malfunction. Therefore, the brake pipeline is a very important component in the system. The quality of the train braking system equipment and its pressure pipeline during the manufacturing process directly affects the safety of train operation.

[0003] The train brake pipeline includes the train main air duct, air spring air duct, dust blowing duct, brake air duct, etc. Most of the main pipelines in the brake pipeline are made of copper pipes with high structural strength and less deformation to ensure their reliability; the branch pipelines in the brake pipeline have been improved from the old rubber hoses that are prone to fatigue and damage to a flexible metal oil pipe that can withstand high temperature and high pressure and is more reliable and durable. This metal oil pipe is not completely metal, but a double-layer pipeline with Teflon lining material and metal snake skin outer coating material. This type of metal oil pipe can provide excellent hydraulic transmission effect, so that the hydraulic energy transmitted from the brake master pump is fully used to push the piston of the slave pump, providing stable braking force and significantly improving reliability. Therefore, it is increasingly widely used in new train brake pipelines.

[0004] However, since metal oil pipes are stronger than traditional rubber hoses, the plasticity of their interface structure is reduced. When the metal oil pipe joints are connected to the copper pipes, they often shake unsteadily. The docking process is time-consuming and labor-intensive, the labor intensity of operators is high, the failure rate is increased, and the quality of the operation and the structural strength and connection reliability of the pipelines after docking cannot be guaranteed. There are even situations where the docking cannot be completed by one person's hands alone. Currently, there are no special docking tools for connecting the metal oil pipe joints and copper pipes to each other in the manufacturing process of the rail train braking system.

[0005] The central symmetry plane refers to a virtual cutting plane that can symmetrically divide an object with a symmetrical structure into two mirror-image parts. The midpoints of the line segments formed by connecting any two symmetrical points on the object that are mirror-symmetric about the central symmetry plane are all on the central symmetry plane.
