Description

A positioning device for blasthole position on tunnel face

technical field

The utility model relates to the field of tunnel construction, in particular to a position positioning device for blastholes on the face of a tunnel.

Background technique

The control of each process link in tunnel blasting construction is the premise of improving construction efficiency. In order to save process time in actual construction, the survey team only put red paint on key holes when setting out blast holes, and other blast holes are located according to the drilled holes. According to the experience and ideas of the workers and the marked hole positions, there is often a big difference between the blast holes arranged on site and the blasting diagram of the scheme design.

Utility model content

The technical problem to be solved by the utility model is to provide a positioning device for blasthole position on the tunnel face, which can quickly project the blasting diagram of the scheme to the tunnel face, and at the same time select different blasting diagrams for projection according to different surrounding rocks, greatly improving Improve the rationality of the blasting parameters and the guidance of the plan, and also save the time for placing the blasting holes and improve the work efficiency.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A position positioning device for a blast hole on the face of a tunnel, comprising a projection unit, the structure of which is as follows: a slide card slot and a projection lens are sequentially arranged in the light path direction of a projection light source; the projection light source is connected to a battery; The lower end of the projection part is provided with a fixing groove, and the fixing groove is installed on the telescopic stand.

Further, a bracket leveling seat is provided between the fixing groove and the telescopic stand; the support leveling seat is set on the telescopic stand through leveling bolts, and a leveling circular air bubble is arranged on the bracket leveling seat .

Further, the projection part is also fixed with an infrared vertical line locator.

Further, a dustproof cover is provided at the front end of the projection lens.

Compared with the prior art, the beneficial effects of the utility model are:

1) The use of this projection projection device can accurately locate the position of the blast hole on the tunnel face in a very short period of time, saving construction time, improving efficiency, and more accurately positioning the blast hole position.

2) According to different geological surrounding rocks, different blasting map slides can be replaced very quickly, and the blasting parameters and hole positions of different surrounding rocks can be determined directly by changing the slides.

3) The device has the advantages of simple structure, strong operability, improved efficacy, and low cost.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

The utility model device includes a projection part, and the structure of the projection part is as follows: a slide card slot 3 and a projection lens 2 are sequentially arranged in the light path direction of the projection lamp source 5; the projection lamp source 5 is connected to the battery 6; the lower end of the projection part A fixing slot 8 is provided, and the fixing slot 8 is installed on the telescopic stand 12 .

A support leveling seat 9 is arranged between the fixed groove 8 and the telescopic stand 12; the support leveling seat 9 is arranged on the telescopic stand 12 by a leveling bolt 11, Leveling round bubbles10. The projection part is also fixed with an infrared vertical line locator 7 . A dustproof cover 1 is arranged at the front end of the projection lens 2 .

Working principle and analysis:

During the tunnel construction process, the position of the blasting positioning device (10m away from the tunnel face) base elevation and tunnel centerline position is determined through the existing guide points in the tunnel, and the bracket height of the positioning device is adjusted through the known base elevation position , and the precise position of the instrument is determined by the infrared vertical locator 7 of the positioning device, and then by observing the leveling circular bubble 10 and the horizontal bubble 4, mobilizing the leveling bolt 11 for rough leveling and fine leveling, to achieve accurate projection height and direction ; Then select different blasting map slides according to different types of surrounding rocks, and use the strong red light of the instrument to project the spot to the face of the tunnel to achieve the purpose and effect of blasting hole positioning.

By adopting the blasting hole position projection positioning device on the face, the blasting map of the plan can be quickly projected to the face, and at the same time, different blasting maps can be selected for projection according to different surrounding rocks, which greatly improves the rationality of the blasting parameters and the accuracy of the plan. Instructive, saves the time of blasting holes and improves the efficiency.
