The technical solution of the utility model is:
A kind of rock gangway photoface exploision eye position angle depth leads control device, comprise a guide bars and two lead angle plates, the rod body of described guide bars is provided with color marking layer, two described lead angle plates are right-angled trapezium, and, the hypotenuse of a described lead angle plate and the angle of bottom are 72 °, and the hypotenuse of lead angle plate described in another and the angle of bottom are 74 °.
Described rod body is made up of cylindrical waddy, and described waddy is coated with and is brushed with a circle red paint, namely described red paint is described color marking layer.The diameter of described rod body is 30-35mm, and length is 3000mm, and described guide bars is straight, round and smooth, and the width of described color marking layer is 20mm.
Two described lead angle plates are welded by angle bar section head and the tail, hollow structure.The height of described right-angled trapezium is 300mm, and the length of bottom is 483mm, and the length of upper base and hypotenuse is determined according to described angle.
The beneficial effects of the utility model are:
1, the utility model is when guide bars and lead angle plate are combined proper use of, can accomplish in engineering precision scope completely " flat, straight, neat, accurate ", improve the order of accuarcy of the angle depth of explosion eye position, and then reach good demolition effect.
2, the utility model guide bars adopts waddy, easily makes and cost is lower, and guide bars is straight, round and smooth, easily be placed in borehole, according to design borehole depth, with red paint at guide bars subscript one marking layer, can not only lead during perforating and can lead dark, convenient and swift.
3, the utility model lead angle plate adopts the angle bar of L30 to process, and shape is right-angled trapezium, and namely the angle of hypotenuse is the angle of snubber, and two lead angle plates can determine the angle of two kinds of snubbers, easy to use.
4, the used time can not put together with gib material for the utility model guide bars, lead angle plate, and management of listing, easily pick and place, convenient management.
5, the utility model is reasonable in design, structure is simple, accurate positioning and cost is lower, and be applied to rock gangway, coal roadway tunneling, it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing illustrates:
Fig. 1 is the schematic diagram that rock gangway photoface exploision eye position angle depth leads the middle guide bars of control device;
Fig. 2 is the schematic diagram that rock gangway photoface exploision eye position angle depth leads the middle lead angle plate of control device;
Fig. 3 is another schematic diagram that rock gangway photoface exploision eye position angle depth leads the middle lead angle plate of control device.
detailed description of the invention:
Embodiment: see Fig. 1-Fig. 3, in figure, 1-guide bars, 2-color marking layer, 3-lead angle plate.
Rock gangway photoface exploision eye position angle depth is led control device and is comprised a guide bars 1 and two lead angle plates 3, wherein: the rod body of guide bars 1 is provided with color marking layer 2, two lead angle plates 3 are right-angled trapezium, and, the hypotenuse of a lead angle 3 and the angle of bottom are 72 °, and the hypotenuse of another lead angle plate 3 and the angle of bottom are 74 °.
Rod body is made up of cylindrical waddy, and waddy is coated with and is brushed with a circle red paint, namely red paint is color marking layer 2, intuitively eye-catching.The diameter of rod body is 30-35mm, and length is 3000mm, and guide bars is straight, round and smooth, and the width of color marking layer 2 is 20mm.
Two lead angle plates are welded by the angle bar section head and the tail of L30, and hollow structure, is convenient to take and grip.The height of right-angled trapezium is 300mm, and the length of bottom is 483mm, and the length of upper base and hypotenuse is determined according to angle.Such as, when angle is 74
0time, the long 400mm of upper base, the long 311mm of hypotenuse; Angle is 72
0time, the long 388mm of upper base, the long 315mm of hypotenuse.
The use of guide bars:
(1) standard borehole:
1. by " determine people, determine machine, location, quantitative " principle, every class borehole (reliever, periphery hole) is by parameters such as eye position, angle, the degree of depth, each subregion (seat in the plane) is at least made a call to one " standard borehole ", then in " standard borehole ", guide bars 1 is inserted, as other shothole drill guiding at the moment.
2. " standard borehole " is generally chosen and is just being pushed up and the borehole at skewback line place.
3. " standard borehole " must member be checked and accepted by inspection, when " standard borehole " is nonstandard, must not inserts guide bars and use as guiding borehole, must jewel hole again, until standard.
(2) guide bars guiding subregion
Just " standard borehole " guide range at top place is defined as the borehole within the scope of 45 °, left and right, and " standard borehole " guide range at skewback line place respectively provides as left and right stalk and the borehole upwards within the scope of 45 °.
(3) standard is used
borehole angle compares with standard borehole, and after guide bars inserts eyeground, two guide bars outer end dimensional discrepancys are not more than 100mm;
borehole eyeground falls at grade, and after guide bars inserts eyeground, guide bars exposes deviation and is not more than 100mm.
The use of lead angle plate:
During perforating, as head-on wall is concordant, directly long for right-angled trapezium limit (going to the bottom) can be attached to and head on (with head-on wall is left and right parallel) on wall, determine snubber angle.As head-on wall is not concordant, must meets head on to step back 200mm at working face and pull on parallel lines, determine snubber angle.
When guide bars and lead angle plate are combined proper use of, can accomplish in engineering precision scope completely " flat, straight, neat, accurate ", improve the order of accuarcy of the angle depth of explosion eye position, and then reach good demolition effect.
The above is only preferred embodiment of the present utility model, and not do any pro forma restriction to the utility model, every any simple modification done according to technical spirit of the present utility model, all still belongs in the scope of technical solutions of the utility model.
