Abstract
The utility model relates to a drilling positioner, in particular to a drilling positioner for strip mines.The outer rim of a sleeve (3) is equipped with at least three downward supporting legs (4).The central section of a hole site indicator rod (5) is sleeved inside the sleeve (3).The upper and lower ends of the sleeve (3) of the hole site indicator rod (5) are respectively equipped with limiting blocks (2) arranged at intervals.The sleeve (3) is in clearance fit with the hole site indicator rod (5).In order to facilitate the finding of the hole site for constructors, the drilling positioner for strip mines can be coated to be red.In this way, the labor intensity of technicians is lowered and the safety hazards caused by artificial factors are avoided, thereby better improving the explosion effect.The drilling positioner has the advantages of simple structure, convenient processing, low cost, convenient operation and easy storage, which is wind-proof and will not fall. The drilling positioner is recyclable and can be used repeatedly, which will effectively improve the work efficiency.
Description
[technical field]
The utility model relates to a kind of boring locator, especially relates to a kind of opencut boring locator.
[background technology]
Known, be most important link in the perforated blasting ore deposit production procedure in the open.The quality of perforated blasting quality directly affects the overall situation of Production of Strip Mine, and the laying of bore position is the preperforative first step, and can rig be the accurate layout of bore position by design its principal element of constructing.Therefore, the opencut that is laid in of bore position seems particularly important.
The distribution method that existing opencut boring is laid is:
According to perforated design, utilize GPS or ruler to measure definite bore position, the technician utilizes the stone in the place to pile up a stone heap as sign in the position of determining, then on stone and water red lacquer on every side to show the position, hole; The problem that preceding method exists mainly contains:
1, because each position, hole is to be piled up by not of uniform size, different 3-4 piece stone to form, thereby cause the Kong Weiyu actual bit of layout to be equipped with certain deviation, error in point measurement is at 10-30cm.
2, workload is big.8 kilograms on each Kong Weixu stone even more; As 5 in Φ 250 rigs that use according to opencut, 3 in Φ 310 rigs, totally 8 large-scale rotary drills constructions.190 borings of every bench drill machine moon construction are calculated, annual need-construction altogether: 190 * 8 * December-18240 hole.Remove 145920 kilograms on stone (18240 * 8 kilograms=145920 kilograms) like this every year altogether, also do not comprise the hole that 8 Φ 140 rigs of assistance unit are beaten, pick up stone actual every year at least more than 150 tons, it is also easy to pick up stone when weather conditions are good, also need snow from the muddy water neutralization when rainy day and winter and pick up stone, this has also increased difficulty for the cloth hole.Simultaneously, stone is also covered by heavy snow easily, makes driller be difficult for accurately seeking the position, hole.
3, waste paint; 0.7 the red lacquer of kilogram barreled also only enough waters 35 left and right sides Kong Wei.Needed 364.8 kilograms (18240/35*0.7=364.8 kilogram) of paint in 1 year, also do not comprise the paint of assistance unit Φ 140 holes layout usefulness, annual paint consumption reality is more than 500 kilograms.The use of annual paint also is a no small spending.
4, the use of stone also causes certain potential safety hazard to the filling in big gun hole; The rock dust that drilling machine construction goes out often mixes with stone and stirs together, when utilizing filling machine filling big gun hole, do not note slightly or to pick up stone untimely, stone just can fall in the hole, often cause the big gun hole plug or cut off detonator in the hole, also need to solve, can't solve sometimes at all, cause the big gun hole to be scrapped with other remedial measure.So just cause potential safety hazard, be difficult to guarantee blasting quality, and this situation happens occasionally in our ore deposit.
[summary of the invention]
The utility model purpose provides a kind of opencut boring locator, described opencut boring locator is by pointing to the position, hole with indicating arm lower end, position, described hole, for position, hole indicating arm injustice or that the position, hole is lower by deadweight can be stable finger in position, position, hole accurately, be convenient to drilling machine construction and can accurately determine bore position, the drilling machine construction personnel find position, position, hole for convenience, the locator of opencut can being holed is painted redness, is convenient to the constructor and finds the position, hole; The utility model is simple in structure be convenient to processing, cost low, easy to use, be convenient to preserve, wind resistance does not fall, repeated use capable of circulation, increase work efficiency effectively.
For achieving the above object, the utility model adopts following technical scheme:
A kind of opencut boring locator, comprise sleeve, limited block, supporting leg and position, hole indicating arm, outer rim at sleeve is provided with at least three supporting legs down, the middle part of position, hole indicating arm is enclosed within the described sleeve, sleeve at position, described hole indicating arm is interval with limited block respectively, sleeve and position, hole indicating arm matched in clearance in two ends up and down.
Described opencut boring locator, the upper end of position, described hole indicating arm is provided with suspension ring.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
Opencut boring locator described in the utility model, after the technician measures definite bore position, the position, hole is pointed in indicating arm lower end, position, hole described in the utility model, because position, hole indicating arm is to be movably arranged in the sleeve, for position, hole indicating arm injustice or that the position, hole is lower by deadweight can be stable finger in position, position, hole accurately, be convenient to drilling machine construction and can accurately determine bore position, the drilling machine construction personnel find position, position, hole for convenience, and the locator of opencut can being holed is painted redness; So not only alleviate technician's the amount of labour, and can reduce trouble and the potential safety hazard that causes because of human factor, thereby can improve demolition effect better; The utility model is simple in structure be convenient to processing, cost low, easy to use, be convenient to preserve, wind resistance does not fall, repeated use capable of circulation, increase work efficiency effectively.
[description of drawings]
Fig. 1 is a perspective view of the present utility model;
Among the figure: 1, suspension ring; 2, limited block; 3, sleeve; 4, supporting leg; 5, position, hole indicating arm.
[specific embodiment]
Can explain the utility model in more detail by the following examples, the utility model is not limited to the following examples, and open the purpose of this utility model is intended to protect all changes and improvements in the utility model scope;
