A method for crimping hanging string crimping tubes and hanging string crimping terminals

Abstract

The invention discloses a method for crimping a dropper crimp tube and a dropper crimp terminal, comprising: adding the crimp tube onto a crimp tube crimping table; adding the crimp terminal onto a crimp terminal crimping table; controlling a four-axis truss manipulator to grip one end of a dropper line and pass into the crimp tube; controlling the four-axis truss manipulator to grip one end, passed through the crimp tube, of the dropper line, and returning to pass again through the crimp tube; controlling a heart ring gripping manipulator to add a heart ring onto the crimp tube crimping table, and fastening the same in a circular sleeve formed by the dropper line; continuously controlling the four-axis truss manipulator to grip the end, returned to pass through the crimp tube, of the dropper line for passing the end through the crimp terminal; controlling the crimp terminal crimping tale to crimp the crimp terminal according to a preset first pressure value; drawing the end, not passed through the crimp tube, of the dropper line so as to fasten the heart ring; controlling the crimp tube crimping table to crimp the crimp tube according to a preset second pressure value. The methodcan provide improved crimping quality and improved crimping quality stability.

Description

technical field [0001] The invention relates to the field of catenary suspension strings, in particular to a method for crimping a suspension string crimping tube and a suspension string crimping terminal. Background technique [0002] With the rapid development of my country's high-speed railway, the railway department has higher and higher requirements for the construction, maintenance accuracy and operation safety of high-speed railway lines. The catenary is an important part of the electrified railway. It is suspended above the electric railway line to provide power to the train. It is generally composed of catenary cables, contact wires, suspension strings, positioning devices, etc. The suspension strings are installed on the catenary cables. , a component used to suspend the contact wire. At present, the domestic and even international production of hanging strings is still using manual production technology, and the crimping quality is unstable, especially because of...

AI Technical Summary

Problems solved by technology

At present, the domestic and even international production of hanging strings is still using manual production technology, and the crimping quality is not stable, especially because the excessive pressure will cause damage to the hanging strings in the crimping tube, and the fatigue resistance of the hanging strings will be reduced.

During the operation, there are often bowing accidents caused by the suspension string breaking due to the production quality of the suspension string, which affects the safety of railway transportation.
