AI Technical Summary

Technical Problem

In the prior art, the operating speed and displacement measurement device of the NPR anchor cable constant resistance body is inconvenient to discharge, and the performance data of multiple anchor cables cannot be measured at the same time. Fixing and disassembling the anchor cable requires manual operation, which is time-consuming and labor-intensive.

Method used

An NPR anchor cable constant resistance body running speed and displacement measuring device including a mounting plate, a detection part and a power part is designed. The detection part includes a solid material mechanism, a transmission mechanism and a measuring mechanism. The solid material mechanism realizes the fixing and disassembly of the anchor cable sleeve through the tensile component and the transmission mechanism. The measuring mechanism measures the running speed and displacement of the constant resistance body in real time through the detection component.

Benefits of technology

The performance inspection of the two anchor cables is achieved simultaneously, reducing the operation difficulty of testers, improving the testing efficiency, and facilitating the fixing and disassembly of the anchor cable sleeve.

Abstract

The invention relates to the field of NPR anchor cable performance detection, in particular to an NPR anchor cable constant resistance body running speed and displacement measuring device, and provides the following scheme aiming at the problems that an NPR anchor cable constant resistance body running speed and displacement measuring device in the prior art is inconvenient to load and unload and cannot measure a plurality of anchor cables at the same time. The device comprises a mounting plate, two detection parts mounted on the outer walls of the two sides of the mounting plate respectively and a power part mounted on the mounting plate, and is characterized in that each detection part comprises a material fixing mechanism, a transmission mechanism and a measuring mechanism which are mounted on the mounting plate; and the material fixing mechanism comprises an installation plate and stretching assemblies installed on the outer walls of the two sides of the installation plate, two sets of tests can be conducted at the same time through the arrangement of the two detection parts, and therefore the detection efficiency is improved. According to the anchor cable constant-resistance body performance testing device, performance testing of two sets of anchor cable constant-resistance bodies can be conveniently conducted at the same time, the anchor cable sleeve can be conveniently fixed and detached, and therefore the testing difficulty of testing personnel is greatly reduced, and the testing efficiency is effectively improved.
