Abstract
The utility model relates to a blasting and hole drilling pasting plate, comprising an arc-shaped thin plate. The blasting and hole drilling pasting plate is characterized in that the shape and size of the arc-shaped thin plate are the same as those of the driving face of a construction tunnel before blasting; the arc-shaped thin plate is divided into two parts by a straight line vertical to the middle point of a bottom edge, and the two parts are hinged with two hinging points; the arc-shaped thin plate is provided with a plurality of circular holes, and the back side of each circular hole is connected to a section of guiding pipe; the amount of circular holes is equal to that of blast holes required in the design of the driving face of the construction tunnel before blasting; the position of each guiding pipe is the same as that of each blast hole required in the design of the driving face of the construction tunnel; the direction and angle of each guiding pipe are the same as those of the corresponding blast holes. The blasting and hole drilling pasting plate is advantageous in that the position of each blast hole can be determined in an accurate and rapid manner based on design requirement; blast holes can be drilled based on the direction and angle required by the design; dust-proof effect can be achieved.
Description
Technical field
The utility model relates to a kind of rock roadway in coal mine construction equipment, a kind of explosion perforating pasting board of more specifically saying so.
Background technology
At present, the rock roadway in coal mine driving methods that adopt the perforating explosion more, the direction of the quality of blasting quality and the layout of borehole and size Control and borehole has much relations; Yet in real rock roadway in coal mine tunneling construction; The position of measuring borehole in strict accordance with designing requirement is relatively more difficult, measures the inaccurate blasting quality that influences, and more loaded down with trivial details when measuring the borehole position; Taken a lot of times, direction and angle according to the strict control of designing requirement borehole during construction are also relatively more difficult.
Summary of the invention
The purpose of the utility model provides a kind of explosion perforating pasting board that can confirm each borehole position according to designing requirement fast and exactly.
The purpose of the utility model can realize in the following manner: explosion perforating pasting board; Include the arch thin plate; The shape and size of construction tunnel driving face are identical before the shape and size that are characterized in described arch thin plate and the explosion, and the arch thin plate is by the straight line separated into two parts perpendicular to the base mid point, and these two parts are hinged and two pin joints are arranged; The arch thin plate is provided with several circular holes; The back side of each circular hole all connects one section guide pipe, and the junction of guide pipe is an end of guide pipe, and the diameter of circular hole is identical with the bore of guide pipe.
The number of the borehole that requires in the design of construction tunnel driving face before the number of described circular hole and the explosion is identical.
The other end of described each guide pipe is in the same plane that is parallel to plane, arch thin plate place; And the position of the borehole that requires in the design of position and the construction tunnel driving face at place is identical, and the direction of each guide pipe and angle are identical with angle with the direction of requirement during corresponding borehole designs.
The utility model compared with prior art has following advantage: simple in structure, easy and simple to handle, can confirm each borehole position fast and exactly according to designing requirement, and can also play the dustproof effect according to the direction and the angle blast hole drilling that require in the design.
Description of drawings
Accompanying drawing 1 is the front view of the utility model.
Accompanying drawing 2 is the utility model profiles at the A-A place.
Among the figure: 1, arch thin plate; 2, circular hole; 3, pin joint; 4, guide pipe.
The specific embodiment
Following with reference to accompanying drawing: explosion perforating pasting board; Include arch thin plate 1; The shape and size of construction tunnel driving face are identical before the shape and size that are characterized in described arch thin plate 1 and the explosion, and arch thin plate 1 is by the straight line separated into two parts perpendicular to the base mid point, and these two parts are hinged and two pin joints 3 are arranged; Arch thin plate 1 is provided with several circular holes 2; The back side of each circular hole all connects one section guide pipe 4, and the junction of guide pipe 4 is an end of guide pipe 4, and the diameter of circular hole 2 is identical with the bore of guide pipe 4; The number of the borehole that requires in the design of construction tunnel driving face before the number of described circular hole 2 and the explosion is identical; The other end of described each guide pipe 4 is in the same plane that is parallel to plane, arch thin plate 1 place, and the position of the borehole that requires in the position at place and the design of construction tunnel driving face is identical, and the direction of each guide pipe 4 and angle are identical with angle with the direction of requirement during corresponding borehole designs.
During construction; Be attached to after the utility model launched before the explosion on the construction tunnel driving face; At this moment the utility model just in time before explosion construction tunnel driving face shape with the size match be posted on; At this moment the scar position pointed to of each guide pipe 4 is exactly the position of the blast hole drilling of wanting in the design, then hammer drill is passed circular hole 2 and carries out perforating with guide pipe 4 and construct, so just can find quickly and accurately borehole the position and can be according to the perforating that requires of borehole direction in designing and angle; And the utility model is simple in structure, operating aspect.
