Abstract
The utility model discloses a multi-direction wall-rock casting monitoring alarm including an existing housing, a cable wire, and a signal transducer. The utility model is characterized in that a drive shaft is connected with an angle transducer in the housing, and a scale measuring tape is arranged on the drive shaft. The instrument head of the scale measuring tape emerges from the lower part of the housing and the drive shaft is also provided with a steel strip wheel. The steel strip wheel is entwined by a steel strip and the steel strip is connected with a thin cable wire. The application is not only suitable to be arranged in the top part of the wall-rock but also applied to any position that is afraid to be touched in the wall-rock. No matter how big the displacement quantity of the casting is, the utility model does not fail like a gear structure as long as the quantity of steel strip is enough and can observe the clearance dimension of the wall-rock casting intuitively in order to arouse the vigilance of the personnel under the well and avoid accidents.
Description
Technical field
The application relates to surrounding rock separation layer displacement warning instrument under the coal mine.
Background technology
With the immediate technology of the application be this alarm of CN2688894Y " surrounding rock separation layer monitoring alarm instrument " of applicant's notice of authorization be in housing, install about two gears, with two toothed rack and the back-moving spring of its engagement, established angle sensor on the gear shaft, the angle transducer lead is connected on signal transmitting device input, signal transmitting device output is connected on the signal output of housing, again two thin steel ropes are separately fixed on the tooth bar, by back-moving spring tension with reset.The other end of thin steel rope is fixed in the country rock boring during use, and alarm is installed in hell.During surrounding rock separation layer, thin steel rope pulling tooth bar rotates, and rotates thereby drive angle transducer, and the output potential signal send the monitoring station to carry out data and handles.The shortcoming of this alarm is: two toothed rack are exposed at the housing outside when 1, installing, and are easy to break ineffective, can not be used for the country rock both sides so can only be used for the country rock top.Even when being contained in the top, also often knocked over instrument by other staff, cause damage.2, owing to structural restriction, the limited length of tooth bar, when surrouding rock deformation is moved greatly, tooth bar will break away from gear and be reduced in the boring ineffective.3, the demonstration of surrounding rock separation layer situation is not directly perceived, can only just know the absciss layer situation when taking place to report to the police.Therefore be sought after its improvement.
Summary of the invention
The application's purpose is to overcome the deficiencies in the prior art to make improvements, and designs a kind of multi-faceted surrounding rock separation layer monitoring alarm instrument.
The application's technical scheme is: it comprises existing housing, wire rope and signal transmitting device, it is characterized in that in housing, having power transmission shaft to be connected with angle transducer, the scale tape measure is installed on the power transmission shaft, scale tape measure head exposes from lower housing portion, on power transmission shaft, also be connected with wheeled steel, winding steel on the wheeled steel, steel band and seizing wire link together.
Its operating principle is: when down-hole country rock generation bed separation displacement, the seizing wire pulling wheeled steel that is fixed in the measured hole rotates, and rotates thereby drive angle transducer, send the displacement signal of telecommunication, simultaneously, drive the scale tape measure and also from housing, stretch out, directly show the surrounding rock separation layer situation.
Its good effect is: the scale tape band is flexible when 1, using, and is not afraid of collision no matter how long all stretch out, and does not damage when running into, and restores to the original state automatically when knocking over.This structure not only is fit to be installed in the country rock top, can both use in the position that any fearness of country rock is bumped.So be called multi-faceted surrounding rock separation layer monitoring alarm instrument.
2, owing to adopt the wheeled steel structure, steel band twines on it, no matter the bed separation displacement amount is much, as long as the steel band amount is enough, just can not resemble the gear structure malfunctioning.
3, during surrounding rock separation layer,, can observe the gap length of surrounding rock separation layer intuitively, cause personnel in the pit's vigilance, avoid having an accident by being exposed at the outer steel ruler of housing.
Description of drawings
Fig. 1 is the front view of the embodiment of the present application, and Fig. 2 is the lateral view that the application implements to survey.
Marginal data: 1-anchor fluke 2-fixed claw 3-thin steel rope 4-set bolt, 5-steel band 6-wind spring 7-invar tape 8-housing 9-power transmission shaft 10-wheeled steel 11-angle transducer 12-transmitter circuit plate 13-cable interface.
The specific embodiment
As shown in Figure 1 and Figure 2, enumerate the structure chart that to survey two displacement points among the embodiment.As seen from the figure, the identical structure of two covers about it comprises, existing only just wherein a cover be described.In housing 8, the transmitter circuit plate 12 and the cable interface 13 of angle transducer 11, band RS-485 interface at first is installed, the line road of going forward side by side connects.Can directly be connected by cable interface 13 with coal mine safety monitoring system.
The power transmission shaft 9 that rotates with the angle transducer axle is arranged in housing 8, be tied with wind spring 6 on power transmission shaft 9, wind spring 6 connects one section invar tape 7, and invar tape 7 is appeared from lower housing portion.
Also have wheeled steel 10 on power transmission shaft 9, be tied with steel band 5 on the wheeled steel 10, steel band 5 is connected with thin steel rope 3 in the anchor hole by bolt 4, and during use, an end of thin steel rope is by anchor head 1 fixedly in the anchor hole.
