Embodiment Construction

[0027] A blasthole drilling positioning device (see figure 1 ), which includes a positioning rod 1, a telescopic rod 2 is fixed horizontally on the top of the positioning rod 1, and an angle measuring instrument 3 is fixed upward on the top of the telescopic rod 2.

[0028] The positioning rod 1 is provided with a level 14; the level 14 is fixed on the middle and upper part of the positioning rod 1 .

[0029] The telescopic rod 2 includes an outer rod 7 and an inner rod 8, and the inner rod 8 and the outer rod 7 are fixed by a fixing ring 9; a rubber ring is arranged inside the fixing ring 9.

[0030] The angle measuring instrument 3 includes a semicircular dial, the front and back of the semicircular dial are marked with an angle value 6, the center of the semicircular dial is movably connected to a laser emitter 5, and the light-emitting end of the laser emitter 5 points to the angle Value direction; the 0 scale of the semicircular dial is parallel to the telescopic rod 2. ...

Abstract

The invention discloses a blast hole punching and positioning device and positioning method. The positioning device comprises a positioning rod (1), wherein an expansion link (2) is transversely fixedat the top end of the positioning rod (1), and an angle meter (3) is fixed upwards at the top end of the expansion link (2); in positioning, the top end of the positioning rod (1) is fixed on a working surface, and the positioning rod (1) is vertical to the working surface; by adjusting the position of an inner rod of the expansion rod, the angle meter (3) is aligned to a position to be punched;the direction of a laser emitter (5) of the angle meter (3) is adjusted to be 90 degrees; the inner rod is fixed together with an outer rod by a fixing ring; and punching is performed along the laserbeam, and then a blast hole vertical to the working surface can be obtained; and therefore, the technical problems of the prior art that angle error is great and blasting operation cannot reach an expected effect due to the adoption of manual measurement for blast hole positioning when blast hole punching is performed in a coal mine tunnel are solved.

Description

technical field [0001] The invention belongs to blasthole drilling technology in coal mines, in particular to a blasthole drilling positioning device and positioning method. Background technique [0002] The continuous advancement of blasting technology has greatly reduced the cost of mine roadway excavation and increased the speed of footage. When using blasting technology to excavate rock roadway or coal roadway, the cut hole is the blast hole that plays a decisive role in the circular footage, the auxiliary hole is the blast hole that continues to collapse rocks, and the peripheral hole is the blasted rock around the roadway to finally form the design outline of the roadway section Whether the parameters of blastholes and surrounding holes are arranged reasonably or not will directly affect whether the roadway is formed regularly, and whether the location of the blastholes is accurate plays a key role in the blasting effect; Using the length of the steel tape to measure ...
