Abstract
The utility model provides a roadway surface distance measuring device. The roadway surface distance measuring device comprises four anchor rods, four reference platforms and a laser distance measuring instrument, wherein the four anchor rods are respectively inserted at the top plate, the base plate and two sides of the roadway; the four reference platforms are respectively fixedly arranged at one end of each anchor rod, which is exposed from the roadway; and the laser distance measuring instrument is fixedly arranged on any reference platform. The roadway surface distance measuring device, disclosed by the utility model, has the advantages of efficiently reducing measurement error of displacement on the surface of the roadway and improving measurement efficiency by arranging the anchor rods on the top plate, the base plate and the wall surfaces of the two sides of the roadway, arranging the reference platforms serving as measuring base points on the anchor rod and utilizing the laser to measure the distance.
Description
Technical field
The utility model relates to the coal mining technology, relates in particular to a kind of tunnel surface distance measurement mechanism.
Background technology
The displacement on tunnel surface is that the monitoring content is pressed in the most basic ore deposit, tunnel, comprises that mainly tunnel roof-to-floor convergence, tunnel two help to move nearly amount, the amount of crushing and group's displacement.According to monitoring result, can calculate tunnel surface displacement speed, the drift section convergency factor.Through drawing displacement, velocity of displacement and getting working face position and time relation curve, can analyze the deformation of the surrounding rock in tunnel rule, measure stability of surrounding rock and roadway support effect.
The tunnel surface displacement generally adopts the cross method of layouting, and vertical direction and two is helped horizontal direction boring at the roof and floor middle part, timber is installed, is surveyed nail etc. and measure basic point.At present, the key instrument of measurement tunnel surface displacement has steel tape, measuring staff, survey rifle, convergence gauge etc.Wherein, steel tape is the most commonly used in the tunnel surface displacement is measured, but measuring error is big, needs two people completion at least and influences normal pedestrian and transportation; Measuring staff, survey rifle and convergence gauge complex structure are not easy to carry.
The utility model content
The utility model provides a kind of tunnel surface distance measurement mechanism, to solve the big defective of measuring error in the prior art, improves measuring accuracy and efficiency of measurement.
The utility model provides a kind of tunnel surface distance measurement mechanism, wherein, comprising:
Be used for being plugged in respectively four anchor poles that back, base plate and two are helped;
Four reference platforms are fixedly installed on the end that said anchor pole exposes respectively from said tunnel;
Laser range finder is fixedly installed on arbitrary said reference platform.
Aforesaid tunnel surface distance measurement mechanism, wherein, preferably, said reference platform comprises:
Square steel plate, a side of said square steel plate are provided with and are used for the nut that is fixedly connected with said anchor pole; And said anchor pole is provided with the external thread that is complementary with said nut.
Aforesaid tunnel surface distance measurement mechanism, wherein, preferably: it is bonding through cementing agent and said tunnel that said anchor pole stretches to the inner end in said tunnel.
The tunnel surface distance measurement mechanism that the utility model provides is through installing anchor pole on the top board in tunnel, wall that base plate and two is helped; Reference platform is set as measuring basic point on anchor pole; Utilize laser to find range, effectively reduced the measuring error of tunnel surface displacement, improve efficiency of measurement.
Description of drawings
The tunnel surface distance measurement mechanism that Fig. 1 provides for the utility model embodiment.
Embodiment
The tunnel surface distance measurement mechanism that Fig. 1 provides for the utility model embodiment, comprising four anchor poles 1, four reference platforms 2 and 3, four anchor poles 1 of laser range finder be respectively applied for be plugged in back 5, base plate 6 and two helps 7, imbed in its wall; Reference platform 2 is fixedly installed on the end that anchor pole 1 exposes from the tunnel, laser range finder 3 is fixedly installed on above-mentioned arbitrary reference platform 2.
As shown in Figure 1, before the measurement, help the boring of 7 walls center at top board 5, the base plate 6 and two in tunnel earlier; Lay anchor pole 1 again; At the exposed parts installing reference platform 2 of anchor pole 1, on reference platform 2, install laser range finder 3 again, can choose a reference platform 2 wantonly and install.For example, present embodiment is installed in the A platform with laser range finder 3 and is example, and is as shown in Figure 1, and laser is beaten in B platform center, obtains the distance between the AB; Successively laser is got to the center of C and D reference platform again, obtained the distance between AC, AD and the CD.
In practical application, reference platform 2 comprises square steel plate 21, and a side of square steel plate 21 is provided with and is used for the nut 22 that is fixedly connected with anchor pole 1; And anchor pole 1 is provided with the external thread that is complementary with nut 22; Steel plate has foursquare plane surface, and its length of side is 50-80mm, and laser range finder 3 adopts mining intrinsic safety type country rock surface displacement laser range finder.
Further, it is bonding through cementing agent 4 and tunnel that anchor pole 1 stretches to the inner end in tunnel, and the part that anchor pole 1 is embedded in the tunnel is more firm.
The tunnel surface distance measurement mechanism that the utility model embodiment provides is through installing anchor pole on the top board in tunnel, wall that base plate and two is helped; Reference platform is set as measuring basic point on anchor pole; Utilize laser to find range; Effectively reduce the measuring error of tunnel surface displacement, improved efficiency of measurement.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
