Problems solved by technology

Moreover, the existing monitoring instrument has a complex structure and is not easy to install, and manual recording is not only a large workload, but also very time-consuming, and the deformation data of the anchor rod and anchor cable cannot be transmitted to the processing center in time, and manual recording is relatively prone to errors
[0003] Sudden instability of surrounding rock, due to its high nonlinearity and uncertainty, is difficult to effectively control and monitor in actual production, and this is one of the biggest hazards in support engineering
The manual recording of bolt deformation used in the existing technology can only record the size or pressure parameters at a certain point in time, but this method cannot effectively distinguish between slow changes and sudden changes, and cannot transmit data in real time and accurately. Moreover, The recorded reference parameter is single
Moreover, when a sudden change occurs, because the anchor rod is damaged, such as a break, the monitoring device will often be destroyed, and it is impossible to have monitoring data.

Abstract

The invention relates to a deformation anchor rod / anchor cable monitor, monitoring system and monitoring method. The deformation anchor rod / anchor cable monitor comprises a pressure sensor, a displacement sensor and a monitoring instrument, wherein the pressure sensor and the displacement sensor are arranged on an integration platform and are connected with the monitoring instrument arranged on the integration platform. The displacement sensor comprises a rolling assembly and a sensing device. The rolling assembly is externally wound by a haulage rope, wherein the open end of the haulage rope is connected with the end portion of a deformation anchor rod / anchor cable; the rolling assembly is internally provided with an elastic component to enable the rolling assembly to reset; the rolling assembly is connected with the sensing device; when the anchor rod / anchor cable deforms, the rolling assembly is driven to rotate via the haulage rope, and the sensing device detects the displacement amount of the rolling assembly and transmits the data to the monitoring instrument; and the monitoring instrument can carry out sound-light alarm according to the measured data. The deformation anchor rod / anchor cable monitor is simple in structure, convenient to use and timely in feedback, and can effectively improve production efficiency and reduce the occurance of geological disaster accidents of mine safety accidents and landslides and the like.

Description

technical field [0001] The invention relates to a geotechnical engineering support technology, in particular to a deformed anchor rod and cable monitoring instrument, a monitoring system and a monitoring method thereof. Background technique [0002] At present, the core of the third-generation geotechnical engineering support technology is the combined support technology of constant resistance and large deformation bolt and anchor cable. However, there is still no breakthrough in real-time monitoring and early warning of rock dynamic disasters and landslides in the stope. The site where the combined support technology of anchor and cable with constant resistance and large deformation is applied is still in the state of manually recording the force and deformation of the end of the anchor (cable). Moreover, the existing monitoring instrument has a complex structure and is not easy to install, and manual recording is not only a large workload, but also very time-consuming, an...
