Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the technical solution of the utility model in detail.
Fig. 1 shows and ground fissure monitoring device of adopting of the present utility model is laid in front view around surface cracks, and Fig. 2 is vertical view, adopts ground fissure monitoring device across the both sides at surface cracks.Specifically, adopt ground fissure monitoring device and comprise fixed bar 11, fixed bar 12, vertical measuring staff 13, horizontal measuring staff 14, straight connecting rod 15 and two leveling pedestals 16,17.Wherein, fixed bar 11 is connected with the lower end of vertical measuring staff 13 by leveling pedestal 16, and fixed bar 12 is connected with the lower end of straight connecting rod 15 by leveling pedestal 17.The right-hand member of horizontal measuring staff 14 is connected with the upper end of vertical measuring staff 13, and the left end of horizontal measuring staff 14 is connected with the upper end of straight connecting rod 15.Vertical measuring staff 13 and horizontal measuring staff 14 are extensible link mechanism.
During use, mode is laid according to shown in Fig. 1 and Fig. 2, the fixed bar 11,12 adopting ground fissure monitoring device is individually fixed in ground fissure both sides, by adjusting the orientation of fixed bar 11,12 and regulating WidFin spiral on leveling pedestal 16,17, vertical measuring staff 13 is made to be parallel to surface level perpendicular to surface level, horizontal measuring staff 14.When ground fissure generation form changes, record vertical measuring staff 13 and the respective stroke of horizontal measuring staff 14, the wherein wide variety in the stroke reflection crack of horizontal measuring staff 14, the drop in the stroke reflection crack of vertical measuring staff 13, achieves the monitoring to About Ground Fractures ' Development process.
Of the present utility modelly adopt in ground fissure monitoring device, vertical measuring staff 13 and horizontal measuring staff 14 are extensible link mechanism, have scalability.For the stroke of the vertical measuring staff of Measurement accuracy 13 and horizontal measuring staff 14, the utility model adopts the extensible link mechanism of following form: extensible link mechanism comprises the different A steel pipe of diameter and B steel pipe, the left end of the B pipe that diameter is less just can be embedded in the right part of A pipe, can regulate stroke according to actual conditions; Engraved scale mark in B pipe outside, minimum scale is 1mm.Further, for reducing the resistance in telescopic process, all lubricated is done in the outside of the inside of A pipe and B pipe.In preferred embodiment of the present utility model, the diameter of A pipe is 10mm, thickness of pipe 3mm, length 25cm; The diameter of B pipe is 8mm, thickness of pipe 2mm, the preferred 40cm of length.The extensible link mechanism that vertical measuring staff 13 and horizontal measuring staff 14 adopt can be identical, also can be different, and such as the length of horizontal measuring staff 14 is greater than the length of vertical measuring staff 13, is applicable to the situation that ground fissure wide variety is violent.
In an embodiment of the present utility model, can at increase right angle, horizontal measuring staff 14 two ends connecting rod, with reference to figure 1, horizontal measuring staff 14 right-hand member is connected with vertical measuring staff 13 by a right angle connecting rod, and horizontal measuring staff 14 left end is connected with straight connecting rod 15 by another right angle connecting rod.Choose the right angle connecting rod of suitable dimension, the size that can reduce for other critical piece (as vertical measuring staff 13 and horizontal measuring staff 14) limits.
In practical application, ground fissure monitoring device of adopting of the present utility model can carry out on-the-spot dismounting according to field observation condition, flexible and convenient to use.Below installation process is laid at the scene briefly describing the utility model embodiment.
First, fixed bar 11,12 is laid.According to the distributional pattern of the ground fissure of up-to-date generation, choose the larger ground fissure of wherein indicating characteristic as monitoring target, laying in fixing process, the primary form of ground fissure can not be affected, and according to the range of monitoring device, both sides fixed bar 11,12 correspondence is laid, distance between fixed bar and crack should control at about 15cm, and the occurrence near normal in the line of two fixed bars and crack, fixed bar 11,12 bottom is treated to apicule type, utilize weight that fixed bar is embedded earth's surface, insert depth is advisable with more than 1m.
The second, leveling pedestal 16,17 is installed.Leveling pedestal is connected with fixed bar, regulates WidFin spiral, make the horizontal bubble of leveling pedestal placed in the middle, make the leveling pedestal 16,17 at two ends all be in horizontality.Leveling pedestal can reduce monitoring device in an initial condition because there is angle to the fixing rough error that observation data is introduced, be conducive to Obtaining Accurate crack delta data, accurately the Characteristics of Evolution of geological information in reflection About Ground Fractures ' Development process.
3rd, vertical measuring staff 13 is installed.Utilize connecting rod to be connected with the leveling pedestal 16 on the right by vertical for telescopic measuring staff 13, be screwed.
4th, horizontal measuring staff 14 is installed.Utilize connecting rod to be connected with leveling pedestal by the left end of horizontal for telescopic measuring staff 14, be screwed; Connecting rod is utilized to be connected on the top of the right-hand member of horizontal measuring staff 14 with vertical measuring staff 13, then the stroke of vertical measuring staff 13 is regulated, the two ends, left and right of horizontal measuring staff 14 are similar to be on a horizontal line, with the junction of the sincere horizontal measuring staff 14 of screw with vertical measuring staff 13.
5th, field monitoring and reading.The initialization of finishing device, the original value of recording level measuring staff 14 and vertical measuring staff 13, according to mining progress and the fltting speed of workplace, arrange monitoring frequency, when observing at the scene, reading on the direct reading of observation personnel two measuring staffs, estimates and reads 0.1mm, and the difference of different time observed reading and original value is fracture width and the drop situation of change at mining active process.
Visible, because ground fissure monitoring device of adopting of the present utility model can carry out on-the-spot dismounting according to field observation condition, therefore on-the-spot fixed bar can only be retained in practical application, remaining component detachably gets off to supply other monitoring place to recycle, be easy to carry transport, effectively can reduce on-the-spot control and instrument quantity, lowering apparatus use cost.
Below be described in detail the technical solution of the utility model in conjunction with specific embodiments, specific embodiment understands thought of the present utility model for helping.The derivation that those skilled in the art make on the basis of specific embodiment and modification also belong within the utility model protection domain.
