A detection ruler and method for contact rail bracket mounting surface related to rail transit

Abstract

The invention relates to the field of the technical science of track traffic engineering, and in particular relates to a ruler for detecting a mounting surface of a contact rail support related to the track traffic and a use method of the ruler. The ruler is characterized in that a left slide block and a right slide bock of a vertical vernier frame are respectively arranged on supports of a left vertical main ruler and a right vertical main ruler, two sides of a vertical vernier frame left slide block and a vertical vernier frame right slide block are in embedding connection with a main ruler support, the center of the main ruler support is provided with a handle, the right side of the handle is provided with a horizontal level pipe, a main vernier frame slide block is arranged on the main ruler support, and the main ruler support is formed by the way that a second main ruler support is embedded into a cavity of the first main ruler support, wherein the detecting range is 820mm-2120mm. The ruler provided by the invention is multipurpose, and simple and accurate to assemble, disassemble and use, can meet the requirements such as the ballast beds with different types, the height, the precision detection and the construction control, can effectively control the concrete height of the ballast bed, can meet the installing requirement of the contact rail, can improve the surface evenness of the concrete and can save the concrete, and can detect the ultrahigh value of a curve rail, and is high in measurement precision, safe and reliable.

Description

[technical field] [0001] The invention relates to the scientific field of rail transit engineering technology, and mainly relates to a measuring ruler and a method for detecting the mounting surface of a contact rail bracket of rail transit. [Background technique] [0002] The subway traction power grid is a transmission line that transmits electric energy to subway trains. Its main function is to provide electric energy to subway trains through the pantograph or electric shoe on the train. The traction grid used in domestic urban rail transit mainly consists of three forms, including: flexible overhead catenary, rigid overhead catenary and contact rail system. Among them, the contact rail system is more commonly used in my country's subways. The contact rail system is composed of insulating support device, contact rail, end elbow, intermediate joint, expansion joint, central anchor, protective cover, grounding protection system, lightning protection system and other parts....

AI Technical Summary

Problems solved by technology

However, when the contact rail is parallel to the track and installed on the track bed, the height and flatness of the contact rail bracket mounting surface are required during construction, and there is no special equipment or method to meet the requirements in the prior art. It directly and indirectly affects the construction accuracy, which leads to problems such as the inability to determine the positioning and installation of the contact rail due to the large construction error of the installation surface of the contact rail bracket, which is not safe and reliable enough.
