Abstract
The utility model relates to an inclining blast-hole and drill-hole locale position finder, which solves the problems by providing an inclining blast-hole and drill-hole locale position finder which can effectively ensure the drill declining blast-hole to conform to the design requirements without communicating both holes or influencing the blasting effect, which is characterized in that the utility model comprises two parallel rulers with a one-meter-distance, and two connecting bars, wherein the bottoms are connected with the angle squares marked with angles calculated to correspond to distances. The inclinations of the blast-holes are directly fixed with the angles marked on the angle squares to make the auger stems of both drills overlap with both movable rules, and thereby achieving the goal of fixing the inclinations of the blast-hole.
Description
Technical field
The utility model relates to aid in the stone drifting, is the on-the-spot position indicator of a kind of grip hole jewel hole definitely.
Background technology
In stone drifting, fractured rock is a master operation.A large amount of both at home and abroad at present rock breaking method or drilling and blasting methods that use.Therefore, the quality of drill eye blasting work to tunnelling speed, specification quality, supporting effect and driving work efficiency, cost etc., all has bigger influence.Drill eye blasting work good in the tunnelling should reach: blast hole utilization factor wants high, and the consumption of explosive and detonator is low; The drift section size should adhere to specification and the standard of " well lane engineering construction and standards of acceptance ".In order to obtain good demolition effect, the face borehole of must correctly assigning a work can be divided into snubber, auxiliary following and periphery hole three classes by its purposes and position, and its firing order is first snubber, secondly reliever, periphery hole at last.As the saying goes that the tunnel drilling depth is by slotting, the effect of snubber be at first on work plane with certain a part of catalase and dish out, on the basis on a scope of freedom, collapse second scope of freedom, for the explosion of other borehole creates favorable conditions.The quality of slotting effect is to the cyclic advance decisive role.Therefore, work plane borehole reasonable Arrangement snubber reasonable Arrangement mode importantly.Snubber generally is arranged in drift section central authorities near the base plate place, grasps direction when being convenient to perforating like this, and help other most boreholes can be by means of the deadweight avalanche of rock.Particularly to solid rock, should adopt vertical wedge cut, snubber has certain angle of slope, the central authorities that snubber is usually placed in section on the lower side, than about the dark 200mm of other borehole.
Summary of the invention
The purpose of this utility model is: provide a kind of and can effectively guarantee to bore grip hole and reach and want designing requirement, can not make two perforations, influence the on-the-spot position indicator of grip hole jewel hole of demolition effect.
Concrete structural design scheme is as follows:
The on-the-spot position indicator of a kind of grip hole jewel hole is characterized in that: comprise two parallel rulers 1,2, the middle part of ruler 1 fixedly connected channel bar 9, the middle part of channel bar 9 has chute 12, the middle part of ruler 2 is provided with sliding pin, sliding pin is plugged in the chute of channel bar 9; The both sides of ruler 1 are respectively equipped with slide block 3,6, slide block 3,6 connecting connecting rod 10,11 respectively, the lower end of connecting rod 10,11 is vertically connecting an end of bevel protractor 5,8 respectively, bevel protractor 5,8 corresponding respectively ruler 2; The upper end of adjustable rule 4,7 is articulated slide block 3,6 respectively, and the lower end correspondence of adjustable rule 4,7 bevel protractor 5,8.
Spacing between the described ruler 1 and 2 is 1 meter.
On the described ruler 1 and 2, channel bar 9 both sides are respectively equipped with air level.
Useful technique effect of the present utility model is:
When implementing, the on-the-spot position indicator of grip hole jewel hole is placed on the drilling rod of rig, adjust the position indicator air level and make the drilling rod level, corresponding on the bevel protractor, can carry out jewel hole according to the inclination angle of designing borehole.Use through on-the-spot three stone drifting faces, blast hole utilization factor is more than 92%.Before making in this way, blast hole utilization factor only about 85%, so this position indicator can guarantee the angle of grip hole, reaches the blast hole utilization factor height, the purpose that the explosion cyclic advance is many.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 be jewel hole angle and adjustable rule apart from connecting rod apart from correspondence table.
Fig. 3 is that the on-the-spot position indicator of grip hole jewel hole uses figure.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment 1:
Referring to Fig. 1, Fig. 3, the on-the-spot position indicator of a kind of grip hole jewel hole comprises two parallel rulers 1,2, the middle part of ruler 1 fixedly connected channel bar 9, the middle part of channel bar 9 has chute 12, the middle part of ruler 2 is provided with sliding pin, sliding pin is plugged in the chute of channel bar 9; The both sides of ruler 1 are respectively equipped with slide block 3,6, and slide block 3,6 is connecting connecting rod 10,11 respectively, and the lower end of connecting rod 10,11 is vertically connecting an end of bevel protractor 5,8 respectively, bevel protractor 5,8 corresponding respectively ruler 2; The upper end of adjustable rule 4,7 is articulated slide block 3,6 respectively, and the lower end correspondence of adjustable rule 4,7 bevel protractor 5,8.
On the ruler 1 and 2, channel bar 9 both sides are respectively equipped with air level 17,18,19,20.
Spacing between the ruler 1 and 2 is 1 meter.Angle according to jewel hole is adjustable rule 4 and connecting rod 10 and ruler 2 formation triangles, calculate distance and the angle of angle correspondence on bevel protractor 5 of jewel hole, as shown in Figure 2, in like manner adjustable rule 7 constitutes triangle with connecting rod 11 and ruler 2, and distance on the bevel protractor 8 and angle are as shown in Figure 2.
Existing corresponding with distance as calculated angle is engraved on the bevel protractor on the bevel protractor 5,8, directly determines the angle of slope of borehole the drilling rod of two rigs to be overlapped with two adjustable rules by the bevel protractor upper angle, promptly reaches the purpose at definite borehole inclination angle.
When implementing, the on-the-spot position indicator of grip hole jewel hole is placed on the drilling rod 21,24 of rig 22,25, air level 17,18,19,20 makes drilling rod 21,24 levels on adjustment position indicator ruler 1 and the ruler 2, and adjust air leg 23,26, make slide block 3,6 aim at the position of desiring jewel hole, connecting rod 10,11 are parallel to channel bar 9, and drive bevel protractor 5,8 fixes, drilling rod moves with adjustable rule 4,7, aims at needed angle, has marked the good angle as calculated of meter on the bevel protractor 5,8 as shown in Figure 2, drilling rod and adjustable rule 4,7 overlap, and can carry out by the design point of view jewel hole.After using, unclamp bolt 13,14,15,16, ruler 1 and ruler 2 are drawn in, put into instrument container, be easy to carry.
