Steel rail detection method for railway construction

Abstract

The invention discloses a steel rail detection method for railway construction. The method comprises the steps that S1, detection preparation is conducted, specifically, a detection vehicle is placed on a steel rail, a detection block is connected with the steel rail in a clamped mode, a contact block is connected to the top face of the steel rail in an overlapped mode, and a first rotating rod and a second rotating rod are located on a same straight line, so that follow-up detection is facilitated; and S2, primiary detection is conducted, specifically, balls slide along the top surface of the steel rail, when the balls meet a deformation position of the steel rail in the vertical direction, the position of a liquid level plug in a liquid level pipe is changed, and the deformation degree and position of the steel rail are known. According to the invention, the deformation degree of the steel rail is determined by a deformation detection assembly, the internal damage condition is detected by a flaw detection assembly, the detection range is narrowed, the detection precision is improved, deformation and internal flaw detection are carried out in a centralized manner, the operation steps are simplified, and a pretreatment auxiliary assembly can play an auxiliary role in the detection of the deformation detection assembly and before the detection of the flaw detection assembly, so that the detection precision and efficiency are further improved.

Description

technical field [0001] The invention relates to the technical field of railway construction, in particular to a rail detection method for railway construction. Background technique [0002] Railway transportation is a land transportation method. Train vehicles are driven by locomotives on two parallel rails. During the laying process of rails, in order to increase the laying speed, from the leveling of the roadbed, the laying and welding of the track bed and the rails, all The participation of large-scale machinery has greatly increased the construction speed. After the railway is laid, in order to ensure the safety of driving, it is necessary to inspect the rails. [0003] However, the detection speed of rails currently on the market is slow and the operation is cumbersome, and in order to improve the detection accuracy in the detection process, it is necessary to carry out multiple detections of different items, which takes a long time and affects the official opening spee...
