Comprehensive detection device for rail steel structural member

Abstract

The invention discloses a comprehensive detection device for a rail steel structural member, and belongs to the technical field of steel structure detection. A comprehensive detection device for a rail steel structural member comprises a base, two fixing blocks are symmetrically arranged at the upper end of the base, rubber pads are fixedly arranged on the inner walls of the fixing blocks, notches are formed in the upper ends of the fixing blocks, springs A are fixedly arranged at the front ends of clamping blocks, and a plurality of contraction grooves are formed in one side of the upper end of the base. According to the invention, the Leeb hardness tester is arranged to detect the hardness of the fishplate so as to determine whether the steel structural member meets the quality standard, and the Leeb hardness tester can move along the direction of the slide rail through the slide block A, so that the Leeb hardness tester can detect the hardness of different positions of the fishplate. The device is reasonable in design, can effectively detect the hardness of the fishplate in the track steel structural member, is rapid and convenient, and can accurately detect the quality of the steel structural member through the Leeb hardness tester.

Description

technical field [0001] The invention relates to the technical field of steel structure detection, and more specifically relates to a comprehensive detection device for rail steel structure parts. Background technique [0002] Steel rails are the basis for ensuring the safety, stability, comfort and fast transportation of passenger trains. Compared with ordinary lines, railway passenger dedicated lines, high-speed and heavy-duty dedicated lines have stricter requirements on the safety performance of rails. Among them, a large number of steel structural parts will be used to connect the steel rails together during the track installation process. These steel structural parts need to be sampled and tested before being used, so that the quality of the steel structural parts can be guaranteed. The quality of traditional steel structures The quality of the steel structure is often judged by beating the steel structure by manpower, which not only has low work efficiency, but also m...

Among them, a large number of steel structural parts will be used to connect the steel rails together during the track installation process. These steel structural parts need to be sampled and tested before being used, so that the quality of the steel structural parts can be guaranteed. The quality of traditional steel structures The quality of the steel structure is often judged by beating the steel structure by manpower, which not only has low work efficiency, but also makes it difficult to judge whether the quality of the steel structure meets the standard. The patent document with the publication number CN212340858U in the prior art provides a A comprehensive detection device for steel structural parts, the device can perform quality inspection of steel structural parts by setting pressure sensors, detection modules, clamping devices and other structures

Although the device has many beneficial effects, there are still the following problems: when the device detects the fishplate used on the track, it is difficult to quickly and accurately detect its various values, which makes it difficult for the staff to judge whether these steel structural parts are meet quality standards

In addition, in the comprehensive testing equipment for fishplates in other existing patented technologies, such as CN112505144A / CN112678024A, only the corrosion of fishplates is tested, and optical probes are required for the size of fishplates, and fast detection of fishplates of different sizes is not possible. Effective detection, and other fishplate measuring equipment need to be equipped with a separate length measurement mechanism and thickness measurement mechanism, so the number of overall measurement mechanisms is relatively large and bloated. In view of this, we propose a comprehensive detection of track steel structural parts device
