Abstract
The utility model relates to a surrounding rock separated layer monitoring alarm instrument. An outer casing is provided with two tooth gears, two racks engaged with the tooth gears and a reset wind spring; each gear shaft is connected with an accurate rotary potentiometer; each rotary potentiometer is fixed onto a location plate; the casing is provided with a signal transmitter circuit board; a wire of the rotary potentiometer are connected with an input terminal of a transmitter circuit, and the output terminal is connected with a signal output port on the casing. When the utility model is used, it fixes two fine steel cables in different deepness of the surrounding rocks by drillings and fixes the steel cables onto the racks respectively, and the steel cables are strained and put to rest by the reset wind spring. When the surrounding rocks in coal mines deform and deflect from the layer, the fine steel cables can drag the racks to drive two tooth gears to rotate separately, driving potentiometer to rotate and transmitting potential signals. The potential signals are transmitted to a monitoring station to proceed data processing through the transmitter circuit, and the utility model realizes monitoring by subsequent circuit system.
Description
Technical field
The utility model relates to surrounding rock separation layer displacement monitoring and warning instrument under the coal mine.
Background technology
Colliery underworkings and work plane country rock produce inner absciss layer along with the propelling of work plane, in time grasping surrounding rock separation layer collapses to fall and country rock is taked to strengthen supporting measure, the assurance country rock does not produce strides, and therefore, the monitoring, alarming instrument of developing a kind of surrounding rock separation layer situation is necessary.
Summary of the invention
The purpose of this utility model is to satisfy the needs of surrounding rock separation layer monitoring under the coal mine, and a kind of monitoring alarm is provided.
The utility model adopts technical scheme to be: in a shell body, install two gears, with two toothed rack and the wind spring that resets of gears engaged, on each gear shaft, connect accurate rotational potentiometer, each potentiometer is fixed on the location-plate, the signal transmitting circuit board is installed in housing, the lead of potentiometer is connected on the input of transmission circuit, and output is connected on the signal output of housing.During use, at first fix two seizing wires at the country rock different depth, again wire rope is separately fixed on the tooth bar, by resetting wind spring tension and resetting by boring.When country rock under the coal mine deforms absciss layer, seizing wire pulling tooth bar makes two each autorotations of gear, thereby driving potentiometer rotates, the output potential signal, electric potential signal is sent to the monitoring station by cable and carries out the data processing behind transmission circuit, and realizes monitoring, alarming by follow-up Circuits System.
With reference to Fig. 1, Fig. 2 embodiment of the present utility model is described.
Description of drawings
Fig. 1 is the application's a structural representation.
Fig. 2 is the application's a potentiometer signal transmitting device schematic diagram.
Among Fig. 1: 1-left side potentiometer, 2-Left Drive gear, 3-box body, 4-left side tooth bar, 5-left side seizing wire, the right seizing wire of 6-, the right potentiometer of 7-, the right travelling gear of 8-, 9-signal output, the right tooth bar of 10-, 11-wiring board, 12-left side potentiometer location-plate, 13-protecgulum, the 14-screw socket of transferring, the 15-reducing sleeve, the right potentiometer location-plate of 16-, 17-left side wind spring, the right wind spring of 18-.
Concrete enforcement
In box body 3 axis holes, install two gears 2 and 8, and install the tooth bar 4 that is meshed with it and 10 and wind spring 17 and 18, be screwed potentiometer fixed head 12, on each gear shaft, overlap upper joint sleeve, by the Connect Power axis of rotation of a device 1 and 7 of adapter sleeve, potentiometer 1 and 7 is fixed on location-plate 12 and 16; The output lead that signal transmitting 11, two potentiometers 1 of device wiring board and 7 are installed in the compartment of housing 3 one sides connects the transmitter input, transmitter output termination signal output 9, and the effect of transmitter is the output impedance that reduces signal.Signal transmitting device circuit is made of two operational amplifier CA358A and B, the normal phase input end of output termination operational amplifier in the middle of the potentiometer.In addition, in Fig. 2 ,+5V operating voltage offers the reference voltage of potentiometer 2.5V through resistance R and reference voltage circuit TL431AC.With protecgulum 13 on the good bonnet of above Installation and Debugging, and be screwed.
During use, at first in country rock, stamp boring, left and right sides seizing wire 5 and 6 is fixed on different depth in the boring, seizing wire 5 and the 6 switching thread bushs from a band barb pass, and thread bush is inserted in the boring inlet, left and right sides seizing wire is passed from housing 3 again, spin and be fixed on the reducing sleeve 15 by switching screw socket 14, again left and right sides wire rope is fixed on the tooth bar of the left and right sides, is connected to the monitoring station, detect by delivery outlet 9 usefulness cables.During country rock generation absciss layer, the program that the monitoring station is provided with is to signals collecting and handle the realization monitoring, alarming.
Claims (2)
1. surrounding rock separation layer monitoring alarm instrument, it is characterized in that: two gears about in housing, installing, with two toothed rack and the wind spring that resets of its engagement, the axis of rotation of two potentiometers is connected on the gear shaft, potentiometer is fixed on the location-plate, the lead of potentiometer is connected on signal transmitting device input, the output of signal transmitting device is connected on the signal output of housing, and during use, two seizing wires that will be fixed on different depth in the country rock boring again are separately fixed on the tooth bar.
2. surrounding rock separation layer monitoring alarm instrument as claimed in claim 1 is characterized in that: the signal transmitting device is to be made of two operational amplifier CA358A and B.
