Pressing force control devices for CRTSIII type turnout board

Abstract

The invention provides pressing force control devices for a CRTSIII type turnout board. The turnout board is arranged on a base board. The pressing force control devices are arranged at the four corners of the turnout board. The pressing force control devices comprise pressing mechanisms and pressing force measuring mechanisms. The pressing mechanisms comprise force transfer supporting boards for pressing the turnout board, force bearing supporting boards for transmitting pressing force, and transverse supporting boards for connecting the force transfer supporting boards with the force bearing supporting boards. The transverse supporting boards are connected with the base board through fastening screws, and the pressing force measuring mechanisms are arranged on the surfaces, making contact with the turnout board, of the force transfer supporting boards. The pressing force of the turnout board can be effectively controlled, the floating quantity of the turnout board in the self-compacting concrete filling process is well controlled accordingly, the use quantity of non-standard fasteners caused by precision of a track board during fine adjustment of a track is saved, and the pressing force control devices are easy and convenient to use and practical.

Description

technical field [0001] The invention relates to the technical field of self-compacting concrete pouring of turnout slabs, in particular to a compacting force control device used in the pouring process of CRTSⅢ type turnout slabs. Background technique [0002] With the vigorous development of high-speed railways, more and more high-speed railways use CRTSⅢ type plates with completely independent intellectual property rights in my country to accumulate more experience for high-speed railway construction, thereby providing strong technical support for my country's high-speed railway going global strategy . In the self-compacting concrete construction of CRTSⅢ type slab ballastless track of high-speed railway, the control of the compacting force of the turnout slab directly affects the floating amount of the turnout slab during self-compacting pouring, which is an important link to determine the construction quality. At present, a torque wrench is used to measure the compres...

AI Technical Summary

Problems solved by technology

At present, a torque wrench is used to measure the compression force. There are deficiencies in the operation process. First, the torque wrench will be inaccurate after a period of time, and needs to be re-calibrated; then, with the use of the compression device, the tightening screw and the The adjusting nut can become corroded, affecting the accuracy of the compression force
