Description
Technical field
The utility model relates to a kind of multi-point displacement pick-up unit, and particularly a kind of bushing type multi-point displacement pick-up unit, belongs to rock and soil engineering detection technical field.
Background technology
In Geotechnical Engineering operation, as in the recovery process of ore, for ensureing the safety of operation, carrying out monitoring to the change that rock mass internal crack is expanded or compression displacement produces with the propelling of actual mining is one of conventional means.Under comparatively complicated rock mass condition, usually multipoint displacement meter should be adopted to monitor, traditional multi-point displacement monitoring mode mainly adopts type vibration wire multipoint displacement meter, when such displacement meter is installed, because displacement transmission lever is in parallel pencil arrangement, install and often need the larger-diameter boring of Drilling, often can be subject to the restriction of working space condition, when especially installing in the roadway of underground, and need filling jelling agent, and volume, weight are all comparatively large, make troubles to installation; This traditional multipoint displacement meter monitoring device complex structure, there are certain requirements working environment, duty needs to provide electric energy, but working environment is very poor under mine, therefore has the situation of monitors failure to occur during monitoring device.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of multi-point displacement pick-up unit, its structure is simple, processing ease, and cost is low, to working environment without the need to special requirement, the same object obtaining multi-point displacement and relatively change under less borehole conditions can be realized.
The technical scheme that the utility model adopts is: apparatus main body is made up of the tubulose displacement transmission lever of more than the two mutual intussusceptions of tail end, the front end of each tubulose displacement transmission lever is with the elastic claw of stretching out, the tail end of tubulose displacement transmission lever is enclosed within scale ring, scale ring front end is stuck in boring, rear end is with chute, and the pointer in tubulose displacement transmission lever stretches out from chute.
The front end of described scale ring is fixed with the aperture set collar of outer wall with tapering, and aperture set collar is clamped on the nose end mouth of boring, and the chute number of scale ring is identical with the number of tubulose displacement transmission lever, and the position other at chute is processed with scale label.
The front port of described aperture set collar evenly has the two above notches in road, easier in notch position generation elastic deformation, thus aperture set collar more can be able to be firmly fixed with boring.
The beneficial effects of the utility model are: can detect multi-point displacement under single comparatively small bore condition, and greatly simplify installation fixed work order and labour intensity; The structure of device is simple, processing ease, and cost is low, to working environment without the need to special requirement.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Fig. 2 is rear end of the present utility model close-up schematic view.
In figure, each label is followed successively by: tubulose displacement transmission lever 1, elastic claw 2, aperture set collar 3, scale ring 4, pointer 5, chute 6, scale label 7, boring 8, notch 9.
Embodiment
See Fig. 1, Fig. 2.This device is primarily of the mutual intussusception of tubulose displacement transmission lever 1 of some estables, and the tail end of intussusception is contained in shift scale ring 4, and the front end of scale ring 4 is provided with the aperture set collar 3 of one.Each tubulose displacement transmission lever 1 leading section is provided with fixing elastic claw 2, appropriate location in boring 8 is fixed on easily to make tubulose displacement transmission lever 1, tubulose displacement transmission lever 1 end is provided with pointer 5, be placed in the axial slide 6 on scale ring 4, be beneficial to setting displacement transmission lever displacement initial value; Scale ring 4 has the pointer chute 6 identical with tubulose displacement transmission lever 1 quantity, indicate displacement to coordinate displacement transmission lever end scale pointer; The radial direction of aperture set collar 3 has the notch 9 of two or more symmetry, so that be beneficial to the elastomeric deformable of set collar material when installing, it is reliably fixed on aperture.In the tubulose displacement transmission lever 1 of intussusception, for making the scale pointer 5 be arranged in inner tube can be instructed on the scale label 7 of the scale ring 4 on top layer, each tubulose displacement transmission lever 1 successively corresponds to scale finger slips scope at it from inside to outside and arranges an axial groove more.
The material adopted in this device, should adopt that the material with more suitable elastic modulus is outer (is easily pushed into desired location in boring during to be both convenient to installation except tubulose moves hole internal fixtion elastic claw 2 material that transmission lever 1 leading section arranges, have and can be fixed in boring with larger elastic restoring force), all can adopt common iron.
Push in boring 8 one by one by descending for tubulose displacement transmission lever 1 during use, the distance of front end distance hell is depending on detection requirement, in minor diameter, pipe should be more farther apart from hell than major diameter outer tube leading section, to ensure that the hole internal fixtion elastic claw 2 of each tubulose displacement transmission lever 1 front end directly contacts with the hole wall of boring 8, when needs deep hole monitoring, the mode of extension bar can be adopted to extend tubulose displacement transmission lever 1, tubulose displacement transmission lever 1 end stay the length outside boring 8 to ensure the scale pointer 5 on it effectively can indicate change in displacement; Aperture set collar 3 and shift scale ring 4 are embedded in boring 8 mouthfuls to fix, aperture set collar 3 and shift scale ring 4 can adopt and split typely also can adopt integral type.
