Embodiment Construction

[0023] Such as figure 1 , figure 2 , image 3 As shown, the non-horizontal rail car body leveling device used in the leveling process of this embodiment includes square steel 1, and the flatness of the upper plane of square steel 1 is not more than 0.3mm; The first reference block 4 and the second reference block 5 are arranged, and the reference block is welded and fixed on the lower surface of both ends of the square steel 1 . The flatness of the lower plane of the reference block is not greater than 0.3mm, wherein two levelness adjustment bolts 2 are vertically arranged symmetrically on the first reference block 4 at the first end of the square steel, and one is vertically arranged at the second end of the square steel 1. The height difference adjusting bolt 3 at the lateral center position of the square steel 1. The first reference block 4 at the first end of the square steel 1 is provided with 2 screw holes, and the levelness adjusting bolt 2 is screwed into the screw...

Abstract

The invention relates to a non-horizontal rail car body leveling process. A car body is enabled to be in a horizontal state indirectly through a leveling device. The non-horizontal rail car body leveling process includes: utilizing an adjusting bolt and a frame level of the leveling device to adjust the leveling device to be in a horizontal state; taking the leveling device as a reference, utilizing a rolling tape to measure distance between position of an air spring at each of four corners of the car body and the leveling device, and utilizing a jack to adjust height of the four corners of the car body in a balanced manner to realize leveling of the car body. The non-horizontal rail car body leveling process is easy to realize, high in operating accuracy and low in operating intensity and can be widely applied to car body repairing operation.

Description

technical field [0001] The invention relates to a leveling process for a non-horizontal rail vehicle body, and belongs to the technical field of railway vehicle manufacturing processes. Background technique [0002] Before repairing the steel structure of the railway passenger car body, the car body must be in a horizontal state (that is, leveling work), so that according to this benchmark, various repair tasks can be completed, such as digging, replacement, positioning and assembly, etc., especially for similar toilets. The positioning and assembly of the beam of the hanger (each hanger has a high level requirement). However, the general car body repair station only has ordinary rails, and no leveled rails are configured, that is, there is no car body leveling datum. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-horizontal rail car body leveling process to overcome the above-mentioned shortcomings of th...
