Problems solved by technology

The disadvantages of this kind of alarm are: 1. When installing, the two racks are exposed outside the shell, which is easy to be damaged and lose its effect, so it can only be used on the top of the surrounding rock and not on both sides of the surrounding rock.
Even when installed on top, it is often knocked over by other personnel with tools, causing damage
2. Due to structural limitations, the length of the rack is limited. When the deformation and movement of the surrounding rock is large, the rack will break away from the gear and shrink into the drill hole to lose its function
3. The display of the surrounding rock detachment situation is not intuitive at ordinary times, and the detachment situation can only be known when an electrical signal alarm occurs

Embodiment Construction

[0018] Such as figure 1 , figure 2 As shown, a structural diagram capable of measuring two displacement points is given in the embodiment. It can be seen from the figure that it includes two sets of the same mechanical and electrical structures on the left and right, and only one of them will be described now. A fixed claw 2 is installed at the upper end of the fixed pipe 17, and the lower end of the fixed pipe 17 is connected with the mechanical housing 8. The thin steel rope 3 with the anchor claw 1 passes through the fixed rope clip 16 from the fixed pipe 17 and is exposed from the bottom of the mechanical housing 8. Exposed redundant thin steel ropes are wound in the rope storage box 15; there is a transmission shaft 9 in the mechanical housing 8, and the transmission shaft 9 is equipped with a scale tape 7 and a steel belt wheel 10 rotating coaxially, and the measuring head of the scale tape 7 Exposed from the bottom of the mechanical housing 8, the steel belt pulley 1...

Abstract

The present invention discloses a kind of multiazimuth double-functional surrounding rock separation layer monitoring alarm instrument. It includes fixed tube, mechanical shell body, and electric shell body, thin steel wire rope with anchor jaw, angle sensor and signal transducer. It is characterized by that in the mechanical shell body interior a drive shaft, a scale flexible rule and a steel tape wheel are mounted, and in the electric shell body interior an infrared data collector and an infrared data transmission device are mounted. Said invention also provides the working principle of said monitoring alarm instrument and its concrete operation method.

Description

technical field [0001] The application relates to a coal mine underground surrounding rock separation layer displacement alarm instrument. Background technique [0002] The technology closest to this application is the CN2688894Y "Surrounding Rock Detachment Monitoring Alarm Instrument" authorized by the applicant. This alarm instrument is connected with a mechanical casing and an electrical casing on a fixed pipe, and two left and right sides are installed in the mechanical casing. The gear, the two racks meshed with it and the return spring, and then two thin steel cables with claws are respectively fixed on the racks, tensioned and reset by the return spring. An angle sensor is installed in the electrical housing, the rotating shaft of the angle sensor is plugged on the gear shaft, the wire of the angle sensor is connected to the input end of the signal transmitter, and the output end of the signal transmitter is connected to the signal output port of the housing. When i...
