Abstract

The utility model discloses a three-direction gap detector, belonging to a detecting instrument for detecting the displacement deformation of the gap of the geology rock mass. The three-direction gap detector is composed of two parts, one part is a sensor assembly device provided with three mutually vertical displacement sensors, and the other part is a detection frame device composed of detection seat supports correspondingly connected with the three sensors and relevant rods. The three-direction gap detector has convenient installation. The three-direction gap detector can simultaneously detect the displacement of three directions of one detection point on the gap of the rock mass after installed at one time. Through the nuts and the screws on a loosening device, the positions of the two parts can be conveniently adjusted, and detecting requirements of each parameter of the gap of the rock mass in the geology project are conveniently and reliably achieved.

Description

Three-direction gap detector
The utility model possession matter surveying instrument device.
Be used at present in the Geological Engineering between rock mass seam displacement measurement with instrument belong to more folk prescription to, the spot measurement displacement meter is as differential transformer type crack gauge (Fuxin sensor factory product).Yet the structure of rock mass and stress deformation are extremely complicated, and simple folk prescription can not reach the Geological Engineering requirement far away to displacement measurement, and generally speaking, over-borrowing is carried out the measurement of three direction displacement with this unidirectional Displacement Measurement meter in Geological Engineering.This so-called three direction displacement is measured, be actually at same measured object and sew on the displacement measurement that three monodisplacements score of installation are not carried out as a ground, this method is installed trouble, manufacturing and installation with some associate members need be installed respectively for three times, take a lot of work, time-consuming, effort, and the synchronous shift that can not finish three directions on the same measuring point is measured, and the synchro measure of three direction displacements is vital often in Geological Engineering on measuring point.
The utility model purpose is to overcome the difficult point that still can not measure rock mass crack three direction displacement amount in the present Geological Engineering accurately, easily, and a kind of three-dimensional crack gauge is provided.
This three-dimensional crack gauge can be in order to measure geology side slope, mine laneway, crack such as water power dam body and heavy construction or to give the both sides of staying seam parallel, vertical and open to close and change size, because when the geology side slope, mine laneway ... etc. stressed or, usually be reflected in significantly in the variation in crack because of excavation construction causes deformation failure.Therefore this device is geologic hazard, and rock mass engineering project construction or buildings provide the safety monitoring means, also can be its stability analysis Monitoring Data is provided.
Below with reference to the accompanying drawings, describe the utility model in detail
Accompanying drawing 1 is a three-dimensional crack gauge structural representation.Wherein (1) is the rock mass crack, (2), (3) are for installing boring, (4), (5) are mounting rod, (6) be the assembling tube, (7) be test arm, (8) are displacement transducer for survey seat (9), (13), (14), and (10) are the sensor extension line, (11) be link block, (12), (15) are connecting rod.
This Three-direction gap detector is made up of the two large divisions.
A part is to carry out measuring three the mutually perpendicular displacement transducer assembling devices of three direction displacement; Another part is the measurement bay device with three orthogonal survey seat supports.
First, it is sensor assembly for vehicle, shown in accompanying drawing 1 left one side of something, wherein (6) are crack gauge displacement transducer assembling tubes, three inductive frequency type displacement meters or differential transformer type displacement meter or resistance-type displacement meter can be installed in this tube in three orthogonal modes. Connecting rod (12) is arranged at assembling tube top, connecting rod (12) and mounting rod (4) are fixed on the coupling block (11) with nut, mounting rod during use (4) is fixed on cement mortar and installs in the boring (2), and rotating nut can be regulated angle and the upper and lower position of assembling tube (6).
Second portion, it is the measurement bay device, shown in accompanying drawing 1 right-hand part, displacement transducer (9), (13), (14) stretch out the end of assembling tube survey seat (8) all is housed, surveying seat (8) for three is fixed on the test arm (7) with screw thread respectively, test arm (7) is screwed on connecting rod (15), connecting rod (15) and mounting rod (5) are screwed on another connecting block (11), mounting rod during use (5) is fixed on another with sand-cement slurry and installs in the boring (3), and the screw on Panasonic's measuring staff (15) can suitably carry out distance selection up and down according to measuring staff (15) screwing hole site.Surveying seat (8) is to be screwed in by screw rod to survey on the seat arm (7), and rotating screw bolt can be regulated the length of surveying the seat arm.The same with first, can become flexible the nut on the coupling block (11), regulate corresponding with the sensor of first has support upper-lower position and the angle orientation of surveying seat and test arm.Two parts all are to utilize (4) and (5) mounting rod, are fixed on sand-cement slurry in the both sides mounting hole (2), (3) in rock mass crack.Survey the measurement face smooth degree height of seat (8), the precision of measurement is accurate more, and for this reason, the tablet that the Pasting last layer is smooth on the measurement face of survey seat (8) is such as glass sheet.
Need to prove connecting rod (12), measuring staff (15) is selected with the diameter of mounting rod (4) (5), promptly will consider intensity, does not shake after the installation, again can not be too thick according to economy principle.Its length is short more as required good more.Surveying the seat arm is to have adopted band steel plate, and is equipped with the lightening hole structure, so promptly guarantees certain intensity, again weight reduction.
This device regulates indoor can all the installation, then according to two part mounting rod distances, determines the position of mounting hole of tested crack rock mass.After accomplishing fluently mounting hole, be fixed in the mounting hole respectively with sand-cement slurry and get final product.
This three-dimensional crack gauge has solved the difficult problem of the displacement on three directions can not measuring simultaneously in the Geological Engineering for a long time on the same measuring point in rock mass crack, and this device is installed easy to adjust, save time, laborsaving, in Geological Engineering for the test geologic hazard, the safety monitoring means that provide are provided for rock mass engineering project construction or buildings, or provide Monitoring Data for its stability analysis.
Embodiment:
The assembling tube (6) of three displacement meters of assembling adopts commercially available finished product plastic tube to be processed into, its diameter is 114mm, high 115mm, displacement transducer (9), (13), (14) are homemade inductance frequency type displacement meters, and range is 50mm, sensitivity is 1%mm, and this displacement meter is retractable under the effect of spring pressurized.Displacement meter and assembling tube stick with glue connect fixing.Survey seat (8) for three, its housing diameter is 60mm, survey on the seat measurement face and post glass sheet, it is of a size of φ 56mm, and thickness is 3mm, and mounting rod (4), (5) and connecting link (12), (15) diameter are 18mm, test arm (7) is processed into the wide 40mm of an end with the 10mm steel plate, the other end is wide to be 20mm, long is that the plate shape of 300mm, centre have 5 of the lightening holes of φ 20mm.
