The anchor rod 6 is fixed at the position of about 100mm of the roof separation instrument 4 by adopting an anchor rod with the diameter of 18mm multiplied by 1600 mm.
The utility model discloses the theory of operation:
when the top plate and the top plate of the top plate are displaced from the layer, the distance between the inductor 2 and the induction plate 3 is changed; the change is transmitted to the control box 1 through the data line 5, and the control box 1 processes the data into digital signals and displays the digital signals; when the roof separation displacement variation exceeds a set dangerous value, the microcomputer of the control box 1 triggers the acousto-optic alarm system to remind personnel on the operation site to evacuate to a safe place.
When the utility model is used for monitoring the displacement variation of the top plate separation layer, in the process of the separation layer of the old top 7 and the immediate top 8, the inductor 2 fixed on the anchor rod 6 at the bottom of the immediate top 8 sinks along with the immediate top 8, so that the distance between the inductor 2 and the induction plate 3 is changed; the data of the change of the sensor 2 and the sensing plate 3 are transmitted to the control box 1 through a communication line 5; the microcomputer and the a/D conversion module inside the control box 1 process the data into digital signals and display the digital signals on the displacement variation display of the display system. When the variation of the roof separation displacement exceeds a set dangerous value, the microcomputer triggers the sound and light alarm system to give an alarm sound and flashing red light for 'coming pressure of the roof and please withdraw at once'. In the operation site, when the worker hears an alarm sound or sees a withdrawal signal of flashing red light, the worker immediately stops working and withdraws to a safe place.
Because the roof separation layer appearance form of use is different, and the mounted position is different, and the warning sets for the dangerous value difference. In the actual use process, the following matters need to be noted:
1. because the voltage required by the acousto-optic alarm system is higher than the normal standby voltage, the built-in storage battery type digital display top plate separation layer alarm instrument needs to be charged in time according to the regulations, and acousto-optic alarm is guaranteed.
2. When the daily equipment is patrolled and examined, the top plate separation layer alarm instrument of the log display is inspected together, and if the display is found to be abnormal, the professional is contacted in time for processing.
3. A plurality of alarm instruments can be connected according to the requirement, so that the alarm instruments can be displayed in a centralized manner and uploaded.
The utility model has simple structure and convenient manufacture, only needs to install an auxiliary induction system on the basis of the roof separation layer instrument, reduces the resource waste of updating and can be recycled after use; the roof separation displacement variation can be monitored in real time, and data can be displayed, so that compared with the manual detection in the prior art, the time and labor are saved, and the measurement error is small; when the variation of the top plate exceeds a set value, the alarm system gives an audible and visual alarm, so that field operation personnel can evacuate timely, and the construction safety is ensured.
