Advanced hydraulic support navigation detection and inclination angle measurement system

Abstract

The invention discloses an advanced hydraulic support navigation detection and inclination angle measurement system which comprises: a detection device module used for detecting the distance between an obstacle and a forepoling hydraulic support and collecting an inclination angle signal of the forepoling hydraulic support; a signal transfer transmission module that is connected with the detectiondevice module, and is used for summarizing and arranging the received ultrasonic signals and inclination angle signals from each advanced hydraulic support according to the serial number of each hydraulic support and transmitting the signals to the analysis processing module; the analysis processing module that is connected with the signal transfer transmission module, and is used for receiving and analyzing the wireless signals from the signal integration emitter, and immediately sending an alarm to a worker if an analysis result shows that the wireless signals are abnormal; and if the analysis result is continuously abnormal or the abnormal value is large, an instruction is immediately sent out to stop the working mode of the advance hydraulic support. According to the invention, the safety working efficiency of the advanced hydraulic support can be effectively improved, the safety coefficient of the advanced hydraulic support in the working process is improved, and the advancementof intelligent coal mining is embodied.

Description

technical field [0001] The invention belongs to the technical field of coal mine roadway mining, and in particular relates to an advanced hydraulic support navigation detection and inclination measurement system. Background technique [0002] A set of leading hydraulic supports generally consists of two identical hydraulic supports on the left and right and a connecting hydraulic cylinder between the two hydraulic supports. A group of leading hydraulic supports can simultaneously move forward along the direction of the hydraulic supports during the supporting process, and can also realize horizontal movement of the two hydraulic supports at the same time through the expansion and contraction of the connecting hydraulic cylinder between the two hydraulic supports. However, at this stage, the following three situations often occur in the working process of the advanced hydraulic support: first, during the process of advancing or horizontally moving the leading hydraulic suppor...

Problems solved by technology

Third, due to the unevenness of the bottom or top of the roadway, it is easy to cause a single hydraulic support roof plane to be too large in the front and rear directions or the height difference between the left and right hydraulic support roof planes is too large, which will cause the support to fall or malfunction

The occurrence of the above three situations will affect the normal work of the advanced hydraulic support, delay the project and cause certain economic losses, and even endanger the life safety of coal mine workers
