A Portable Rail Profile Measuring Device

Abstract

The invention discloses a portable rail profile measuring device, which is composed of upper, middle and lower parts stacked and joined. A detachable side panel is inserted on the top surface of the upper part. The middle part of the main body is provided with equal intervals along the left and right directions, and there are central threaded mounting holes through the upper and lower surfaces of the middle part of the main body. The internal thread is installed with a cylindrical measuring head, and the vertical position of the measuring head is adjustable. When in use, after splitting the upper, middle, lower, and side panels, install the side panels vertically on the middle from the middle to realize the alignment between the middle and the side of the rail; then use the measuring head to measure the profile of the rail; and the Multiple middle horizontal combinations are suitable for measuring rails of different widths. The invention adopts a modular design, which is convenient for assembly, disassembly and maintenance, and is easy to carry. Wing rail combination profile measurement and grinding quality evaluation.

Description

technical field

[0001] The invention belongs to the technical field of engineering, in particular to a portable rail profile measuring device. Background technique

[0002] Since the reform and opening up, my country's railways have achieved leapfrog development, with qualitative changes in railway operating speed, traffic volume, and vehicle types. At the same time, the interaction force between the wheel and the rail is becoming more and more complex, and the problems of rail corrugation, fatigue damage, side wear, and vehicle stability are becoming more and more prominent. In order to effectively control the occurrence and development of rail defects and prolong the service life of rails, the engineering department gradually promotes the rail profile grinding technology. Through the implementation of rail profile grinding, the wheel-rail contact relationship can be changed, and the occurrence and development of rail defects can be controlled from the root. However, how ...

[0059] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0060] The present invention is to provide a portable rail profile measuring device, comprising a main structure 1, a measuring head 2, a tightening tool 3 and a side plate 4, such as figure 1 , figure 2 shown.

[0061] The main body structure 1 is a cube structure, including a main body upper part 101 , a main body middle part 102 and a main body lower part 103 . The upper part 101 of the main body, the middle part 102 of the main body and the lower part 103 of the main body are all rectangular box structures with equal dimensions, and are stacked and connected from top to bottom.

[0062] Such as image 3 , Figure 4As shown, there are docking protrusions 101a at the four corners of the bottom surface of the upper body 101, and bolt holes are opened on the docking protrusions 101a; the middle part of the bottom surface is designed with a bar-shaped upp...
