Abstract

The invention discloses a method for overhauling a side bearing plate of a main frame of a train by by positioning an overhead contact line with a special tooling, the special tooling is two identicalpositioning measuring units, The specific methods are as follows: At first, that eight side bear plates are arrange in a predetermined position, Install the two positioning measurement unit frames onthe main frame and adjust the tooling, Check the dimensions of the 4 locating pins, After meeting the dimensional parameters, the side bearing plate is fixed on the mounting bracket of the positioning measurement unit from the back through the locking pin and the locking nut, the side bearing plate is fixed and the dimensions of the four locating pins are re-checked, after meeting the dimensionalparameters, the side bearing plate is welded, after cooling, the side bearing plate is checked again, and after meeting the dimensional parameters, the tooling is removed and entered into the subsequent process. The method solves the problems of time-consuming, labor-consuming, difficult measurement, poor dimensional accuracy and flatness in positioning and assembling the side bearing plate of the JJC main frame by improving the existing positioning method of the side bearing plate of the JJC main frame, and greatly improves the production quality and efficiency.

Description

Technical field

[0001] The invention relates to a manufacturing technology of a catenary inspection and repair train, in particular to a method for positioning a catenary inspection and repairing a side bearing plate of a main frame of a train by using a special tool. Background technique

[0002] A new type of JJC type catenary maintenance train is currently produced. The main frame of the catenary maintenance train includes two parallel middle beams 11, and the outer side of the middle beam is provided with support beams 15 on the front and rear sides of each main frame. , Symmetrical mounting brackets are arranged between the center beam 11 and the support beam 15, and two side bearing plates are arranged side by side on the side close to the center beam along the length of the main frame and on both sides of the side bolster 18 on each mounting bracket. Installation frame, each side bearing plate installation frame is equipped with a side bearing plate 9 and each side bearing...
