Abstract
The utility model discloses a monitoring instrument for heaving floor of coal mine tunnel, include: fixed mounting is carving the scale in the fixed plate of tunnel bottom on the fixed plate left side, the fixed plate top is passed through the rope and is moved the union coupling, moves intraductal have be used for moving the soft rope that the pipe changed, soft rope is connected with the steel wire in the fixed plate exit, the steel casing pipe is installed in income drilling department to the steel wire, the steel wire terminal is fixed on carving the device that appears, carves the device that appears and is fixed in drilling department. When the top of roadway bottom plate with two when helping the rock mass produce to warp, the shape device is carved in the extrusion makes the steel wire in steel casing pipe effect rebound down, removes intraductal soft rope and slides along the pulley, makes to remove the pipe and take place to move down, and change numerical value is read out to the scale on on the left of the fixed plate.
Description
Technical field
The utility model relates to a kind of coal mine roadway pucking Monitoring equipment.
Background technology
The instrument that current home and abroad colliery tunnel pucking is measured is numerous, the monitoring mostly concentrating on the machinery to tunnel pucking can not convert displacement amount to and carry out in directly observation, measuring owing to the restriction of various factors makes monitoring can not reach level of automation tunnel pucking simultaneously.
Deep mining is turned to gradually along with to coal mining, tunnel pucking problem day by day becomes serious, drastically influence the normal production of the normal production in tunnel and working face, coal production is had great significance by the deformation mechanism therefore studying tunnel pucking, and more and more building field with "nine squares", efficient colliery for China has higher practical value.
Practical novel content
This practical object is to provide a kind of coal mine roadway pucking Monitoring equipment, it is possible to the change of monitoring tunnel pucking.
Stating object for reaching above, the technical solution of the utility model is:
It is fixedly installed in the retaining plate bottom tunnel, scale is carved on the left of retaining plate, retaining plate top is connected with movable pipe by rope, the soft matter rope for movable pipe changes is had in movable pipe, soft matter rope is connected with steel wire in retaining plate exit, steel wire is provided with Steel Sleeve entering drill hole, and steel wire terminal is fixed on the device of falling wedge, and the device of falling wedge is fixed on drill hole.
Compared with the prior art, the beneficial effects of the utility model are:
The utility model discloses a kind of coal mine roadway pucking Monitoring equipment, size it is carved with on the left of retaining plate, movable pipe is connected to the top of retaining plate by rope, in movable pipe, soft matter rope is cemented on cross bar apparatus structure also through movable pipe middle pulley, soft matter rope is connected with steel wire in the exit of retaining plate, enter drill hole at steel wire and it is fixed with Steel Sleeve, steel wire terminal is fixed on the device of falling wedge, when tunnel roof and floor and two helps rock mass to produce distortion and produce displacement in tunnel, the extruding device of falling wedge makes the steel wire steel wire that moves up move up along Steel Sleeve, in movable pipe, soft matter rope slides along pulley, movable pipe is moved down, change numerical value is read according to the scale on the left of retaining plate, demonstrate the running parameter of tunnel pucking, through data preparation analysis, different geologic conditions can be drawn, lithological change situation.

1 device of falling wedge in figure; 2 steel wires; 3 Steel Sleeves; 4 soft matter ropes; 5 lower sheave combinations; 6 top sheaves; 7 cross bar devices; 8 movable pipes; 9 ropes; 10 retaining plates; 11 retaining plate scales.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Shown in figure 1 and Fig. 2, the utility model discloses a kind of coal mine roadway pucking Monitoring equipment, movable pipe is connected to by rope the top of retaining plate, in movable pipe, soft matter rope is fixed on pulley also to pass the pulley in movable pipe, it is connected with cross bar device at top end stay cord, cross bar device supports movable pipe, and steel wire is fixed on borehole bottom through the Steel Sleeve being fixed on drill hole with the device of falling wedge, connects soft matter rope and steel wire.
When tunnel roof and floor and two helps rock mass to produce distortion, the terrestrial stress extruding device of falling wedge that distortion produces, making the device of falling wedge drive steel wire to be moved, steel wire moves up under the effect of Steel Sleeve, and the junction of steel wire and soft matter rope becomes absent-mindedness, soft matter rope will slide along pulley, movable pipe is moved down, according to the scale on the left of retaining plate, reads the parameter value of change, through data preparation analysis, it is possible to draw different geologic conditions, lithological change situation.
On Steel Sleeve, casting cement makes it the movement of steel wire to be had an impact, and the plank that can scribe elected as by retaining plate, and movable pipe elects the iron pipe of certain mass as, and retaining plate is placed in vertical position and is fixed wtih.
