Description
The utility model relates to a kind of roof delamination monitoring alarm.Be used to monitor the absciss layer situation and the deflection of coal mine roadway roof strata.Also can be used for other mine or tunnel.
The roof delamination monitoring alarm is installed in the boring in tunnel.Its effect is by the measurement of the separating location of coal mine roadway roof strata and deflection being determined the degree of stability of top board, for supporting design provides parameter and strengthens roof control.When the top board unstability, give the alarm when reaching precarious position, prompting must take to strengthen supporting measure, to guarantee that tunnel safety normally uses.
Soviet Union AKC type bolt support top board displacement signal instrument is a kind of similar roof delamination monitoring alarm.This instrument is made up of anchor head, frame, displacement transmission indication mechanism, warning device.Anchor head is fixed on foot of hole, and frame is fixed on the drilling orifice place.Displacement is transmitted indication mechanism mainly by forming with anchor head mobile jib that is connected as a single entity and the copper pipe that is fixed on the frame.Copper pipe is marked with scale, casing pipe sleeve is being arranged on the mobile jib outside copper pipe, and the sleeve pipe when anchor head moves on the mobile jib slides along copper pipe, moves distance but change observation bit by scale.Magnet ring is installed on sleeve pipe, and the connection warning device gives the alarm (to reach the limit value of top board displacement) when sleeve pipe slides into certain position.
The deficiencies in the prior art part is: 1. instrument hangs at the drilling orifice place and reveals the big lane space that influences of length, has limited range simultaneously.2. can only measure the absciss layer value at a position in the boring.
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of outstanding dew length little, the roof delamination monitoring alarm that range is bigger.
The purpose of this utility model also is to make above-mentioned roof delamination monitoring alarm to measure the absciss layer value at a plurality of positions.
The purpose of this utility model can reach by following measure:
The utility model improves the displacement indication mechanism, is made up of anchor head, frame, warning device, lining rope, displacement display unit, several directive wheels and tensioning apparatus.Directive wheel is fixed on the frame, and lining rope is walked around several directive wheels and is connected between anchor head, displacement display unit and the tensioning apparatus.Lining rope passes to the displacement display unit with the displacement of rock stratum between anchor head and the drilling orifice.The displacement display unit demonstrates displacement, and warning circuit is connected.Directive wheel plays a supportive role to lining rope and changes its direction.Tensioning apparatus makes lining rope remain tensioning state, guarantees accurately to transmit displacement.
The purpose of this utility model can also reach by following measure:
Can fix a plurality of anchor heads at the boring diverse location, be equipped with the absciss layer value that corresponding lining rope, displacement display unit, directive wheel and tensioning apparatus can be measured a plurality of positions.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the sketch of embodiment 1 of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Fig. 3 is the sketch of embodiment 2 of the present utility model.
Fig. 4 is the vertical view of Fig. 3.
Fig. 5 is that the A of Fig. 3 is to view.
The utility model is described in further detail below in conjunction with embodiment:
Anchor head 1 and anchor head 2 are made up of plastic body 3 and spring leaf 4 fixed thereon among Fig. 1 and Fig. 2.Anchor head 1 and anchor head 2 usefulness spring leafs 4 are fixed on the measuring point of boring different depth.Frame 5 is fixed on the drilling orifice basal plane.The 6th, warning device is installed on the frame 5.The displacement display unit by demonstration with 9 and magnet steel 10 mounted thereto form.Show with on the scale that shows displacement is arranged, the luminescent material that it is marked with scale or scribbles different colours.Tensioning apparatus is made up of spring 16, pulley 15, geometrical clamp 14.Spring one end is fixed on that the other end is connected with pulley on the frame.Geometrical clamp is installed on the frame.Directive wheel 8,11,13 also is installed on the frame.Show and be with 9 two ends to be connected with 12 with lining rope 7 respectively, the other end of lining rope 7 is connected with anchor head 1.Lining rope 7, show be with 9 and lining rope 12 walk around that to walk around pulley 15 again behind the directive wheel 8,11,13 fixing by geometrical clamp 14.Under the effect of spring 16, lining rope keeps tensioning state.The company's wire clips 17 that connects lining rope 7 usefulness is arranged on the lining rope 7 that enters the frame place.Anchor head 2 is furnished with corresponding lining rope, displacement display unit, tensioning apparatus and directive wheel.
The company's of operation wire clips and geometrical clamp make the lining rope tension during use, and make spring that certain pulling force be arranged, and will show that the scale of band transfers to zero-bit, and magnet steel is installed on the desired location.When between the rock stratum at anchor head 1 or 2 places and the hell basal plane absciss layer taking place, anchor head moves up the lining rope in the hole, be can observe the shift value that shows band by the window on the frame.When shift value reached limit value, magnet steel was connected warning circuit, and warning device sends audible and visible alarm.
The displacement display unit of Fig. 3-roof delamination monitoring alarm shown in Figure 5 by driving wheel 20, show that wheel 19 forms with the friction clutch 21 that is connected them.The axle that shows wheel and driving wheel is installed on the frame 24, and showing on the wheel has scale, and magnet steel 22 is installed.The diameter that shows wheel can play amplification to measured displacement greater than driving wheel.Tensioning apparatus is by the rope drum 18 that clockwork spring is housed and prevent that the ratchet mechanism 30 of its reverse from forming.Rope drum is installed on the frame.Walking around driving wheel from the lining rope 28 of anchor head 29 through directive wheel 27,26 is wrapped on the rope drum 18 through directive wheel 25 again.The clockwork spring of rope drum and ratchet mechanism can only unidirectionally be pulled out lining rope, and make lining rope be in tensioning state.Anchor head 31 is furnished with corresponding lining rope, displacement display unit, tensioning apparatus and directive wheel.Earlier friction clutch 21 is thrown off during use, make to show that taking turns scale is transferred to zero-bit, magnet steel 22 is transferred to desired location, friction clutch 21 then closes.When absciss layer took place in the rock stratum, the lining rope at place, aperture moved up, and drove driving wheel and rotated, and drove by friction clutch simultaneously to show the also corresponding rotation of wheel, and lining rope is pulled out by rope drum.Can observe the roof delamination displacement by showing the scale on the wheel.Warning device 23 is installed on the frame 24, and when displacement reached limit value, magnet steel gave the alarm warning device.
The utility model compared with prior art has the following advantages:
1. the improvement of structure makes survey change direction along the displacement of borehole axial, thereby has reduced instrument along the occupied lane space of borehole axial. Simultaneously range can be increased.
2. the roof spacing layer monitoring alarm that a plurality of anchor heads are installed can be monitored boring multi-point displacement situation of change.
