Abstract
A quick lofting and positioning device for drilling, exploding and hole distributing of a tunnel comprises a rotating plate, a hollow double-thread screw and a long dotting rod, wherein the hollow double-thread screw is perpendicularly arranged in the middle of the rotating plate; groove-shaped screws are arranged on the double-thread screw at intervals; an arc-shaped supporting plate is arranged in a groove of each groove-shaped nut; an inserting rod is inserted in the hollow double-thread screw; a gravity type graduated plate and a scale sliding rack are perpendicularly arranged at the outer end of the inserting rod; a scale rod is arranged in the scale sliding rack; a gap is formed between the inserting rod and the hollow double-thread screw; the inserting rod and the hollow double-thread screw rotate relatively; and a laser pen is arranged on the top of the long dotting rod. The quick lofting and positioning device for drilling, exploding and hole distributing of the tunnel has the advantages that the work procedures of drilling, exploding and hole distributing of the tunnel are simplified, the hole distributing time is shortened, and the quick lofting and positioning device is operated simply, safely and reliably. Compared with the conventional measuring instrument for hole distributing, the quick lofting and positioning device has quite large technical economy advantages; and the drilling and exploding excavation construction progress of the tunnel can be greatly increased.
Description
Technical field
The utility model relates to a kind of laying out apparatus, and a kind of energy substitutes the quick-fried accurately quick location of the tunnel brill cloth aperture apparatus of measuring setting-out.
Background technology
Before tunnel drillhole blasting excavation, in order to guarantee the quick-fried cross dimensions of brill of the tunnel not out break that meets design requirement, tunnel does not train off and deflects, and must bore quick-fried explosive payload etc. to tunnel and carry out accurate Calculation, and boring is accurately measured to cloth hole.Conventional no matter be circular, gateway opening type or u-shaped cross-section tunnel, all adopt and measure the hole that centers, then under the guide of measuring instrument, on excavated section, by manually painting philosophy, drilling hole position is marked, for drill hole of drilling machine location, although the method is accurately very time-consuming, in tunnel bores the regular circulations of operation such as producing quarrel measurement setting-out cloth hole, take long time, in order to change this situation, needed a kind of setting-out cloth hole positioning device badly.
Summary of the invention
The utility model provides a kind of tunnel excavation accurate for boring cloth hole, blast hole position laying out apparatus fast, solve big-and-middle-sized tunnel and all adopted and measure setting-out and lay and bore time-consuming the taking a lot of work of blast hole and wait construction difficult problem, can be widely used in quick cloth hole, various tunnel blastings hole setting-out and construct.
A kind of tunnel bores quick-fried cloth hole speedy lofting positioner, it comprises rotating disk, rotating disk middle part is vertically provided with hollow double threaded screw, on hollow double threaded screw, be interval with slotted nut, in the groove of slotted nut, be provided with arc fagging, hollow double threaded screw inside is inserted with inserted link, inserted link outer end is vertically provided with gravity type index dial and scale balladeur train, in scale balladeur train, be provided with scale bar, between described inserted link and hollow double threaded screw, gap arranges, can mutually rotate between the two, described lofting positioning device also comprises gets stock ready, gets stock top ready and is provided with laser pen.
Above-mentioned arc fagging is folding two sections of formations, and centre connects by pivot pin.
?the beneficial effects of the utility model are: simplify tunnel and bored the operation in quick-fried cloth hole, shortened the cloth hole time, and simple to operate safe and reliable, compared with measuring instrument cloth hole, there is very large technology economy advantage with routine, can greatly accelerate tunnel and bore the excavation construction progress that pops, before each setting-out cloth hole, only need with measuring instrument at the fixed centre bore of excavated section, then with rig fast by centre drill out, manually quick cloth aperture apparatus is arranged on centre bore position, according to various holes parallactic angle degree and radial dimension computed in advance, before one people stands in centre bore, the continuous measuring staff indication of operation setting-out cloth aperture apparatus is layouted, another people stands in tunnel bottom according to the point of measuring staff indication, hold that stock is constantly painted on Rock Profiles or colored pigment indicates bore position, after whole arrangement of boring holes are complete, remove cloth aperture apparatus and just can carry out drilling operating at once, can save a lot of time.

The specific embodiment
As Fig. 1-7, a kind of tunnel bores quick-fried cloth hole speedy lofting positioner, it comprises rotating disk 8, rotating disk middle part is vertically provided with hollow double threaded screw 9, on hollow double threaded screw, be interval with slotted nut 10, in the groove of slotted nut, be provided with arc fagging 11, hollow double threaded screw inside is inserted with inserted link 15, inserted link outer end is vertically provided with gravity type index dial 7 and scale balladeur train 6, in scale balladeur train, be provided with scale bar 5, between described inserted link and hollow double threaded screw, gap arranges, can mutually rotate between the two, described lofting positioning device also comprises gets stock 3 ready, get stock top ready and be provided with laser pen 4.Arc fagging is folding two sections of formations, and centre connects by pivot pin 12.
Project organization of the present utility model and practical principle: quick drill blast hole cloth hole lofting positioning device, formed by two parts, a part is utilized the centre bore getting out on rock, the locating rack of positioner is put in hole, another part is slidably measuring staff and calibration plate rail, under calibration plate rail, there is a centralized positioning pivot pin, can insert in locating rack and freely rotate, on rock when cloth hole, according to radial dimension and the angle of position, each hole computed in advance, operation slide bar scale stretches out slide bar or retracts and can determine the radial dimension of position, hole, can make the angle position of position, hole according to the angle indicating on the index dial of center, both combine and just make the position, accurate hole of each boring.
Specific operation process of the present utility model is as follows: tunnel bores before quick-fried setting-out cloth hole, first determine a centre bore 13 with measuring instrument at excavated section, then on rock, centre bore 13 is come outbreak out fast with rig, manually the center support of cloth aperture apparatus is inserted in petrosal foramen, adjust support relative position, forward and reverse rotation rotating disk 8 drives the together forward and reverse rotation of hollow double end male- pipe 9, 10 of slotted nuts that are arranged on hollow double end male-pipe 9 move inward simultaneously or outwards move, arc fagging in slotted nut 10 external chutes outwards opens or inwardly shrinks.Operation rotating disk 8 rotates and makes arc fagging 11 hold out against hole wall, the central shaft of scale balladeur train 6 is passed to gravity type index dial 7, penetrate in the hollow double end outer spiral tube 9 of the center support of installing on rock, measuring point personnel 2 stand on platform 14, according to the angle in each hole computed in advance and radial dimension, scale bar 5 is retractable to respective length, according to the scale of gravity type index dial 7, utilization is arranged on the laser pen 4 of scale bar 5 terminations, constantly site, accurate hole is put to rock, stand in tunnel bottom and hold the operating personnel 1 of stock 3, constantly according to the laser point of irradiating on rock, to paint or colored pigment point on rock, complete cloth hole operation.
