Simple crack displacement monitor

Abstract

The invention discloses a simple crack displacement monitor comprising a stand column A (1), a stand column B (2), a calibrated disc (4) and a measuring ruler (5). The simple crack displacement monitor is characterized in that a rotating shaft A (3) is fixedly mounted on the stand column B (2). The disc (4), the movable mounted measuring ruler (5) and a pointer disk (6) are fixedly mounted on therotating shaft A (3) in turn. The measuring ruler (5) and the pointer disk (6) are fixedly connected. A rotating shaft B (8) is fixedly mounted the stand column A (1). A movable block (7) is movably mounted on the rotating shaft B (8). The measuring ruler (5) is movably and perpendicularly cooperated with the groove of the movable block (7) and then the movable block (7) stretches out. The simplecrack displacement monitor has the advantages of simple structure, convenient use, real-time monitoring function and high accuracy of measurement data.

Description

technical field [0001] The invention belongs to the technical field of crack detection equipment, and in particular relates to a simple crack displacement monitor. Background technique [0002] After the cracks are formed in mountains, dangerous rock masses, buildings, roads and bridges, the developed cracks will seriously threaten the lives and property safety of the surrounding people at all times, so it is necessary to monitor the cracks in real time to prevent safety accidents and property losses . For the monitoring of developing cracks, simple manual monitoring with tools such as a tape measure is usually used. This method has the problems of low measurement accuracy and inability to obtain monitoring data in real time. Certain subjective factors are dominant and cannot accurately record the development status of cracks. It will have a serious impact on the selection of disaster prevention and mitigation measures and the reasonable timing of arrangement measures. [...

Problems solved by technology

For the monitoring of developing cracks, simple manual monitoring with tools such as a tape measure is usually used. This method has the problems of low measurement accuracy and inability to obtain monitoring data in real time. Certain subjective factors are dominant and cannot accurately record the development status of cracks. It will have a serious impact on the selection of disaster prevention and mitigation measures and the reasonable timing of the arrangement measures

[0003] At present, there are also some measuring equipment designed for cracks. Although the above-mentioned problems of low measurement accuracy and real-time monitoring have been solved, the equipment has the problems of too complicated structure and inconvenient use.
