Abstract
The utility model relates to a guiding mechanism for drifting belonging to the bursting technology. An adjustable wedge-shaped eye guiding mechanism is mainly composed of a connecting plate, a bolt, a spiral arm, a deflection tube and a protractor. The spiral arm can be rotated around the bolt so as to make the separation angle between a deflection tube centerline and a bottom plane of the connecting plate is equaled to the separation angle between a drill rod and a drivage face. The adjustable wedge-shaped eye guiding mechanism is first adjusted in the direction of a blasthole to make the separation angle between the deflection tube centerline and the bottom plane of the connecting plate to be equaled to the separation angle between the drill rod and the drivage face, and to make the bottom plane of the connecting plate is parallel to the drivage face; and then a drill bit and the drill rod are arranged into the deflection tube and are drilled forwards; under the condition of the smoothness of the drivage face, the separation angle between deflection tube centerline and the bottom plane of the connecting plate is the same to the separation angle between the drill rod and the drivage face; when the drill bit and the drill rod are entered into a rock in a certain deepness, after the drilling hole direction is confirmed, the adjustable wedge-shaped eye guiding mechanism can be disassembled.
Description
Affiliated technical field
The utility model relates to a kind of guiding device that is used for tunnelling, belongs to blasting technique.
Background technology
At present, when adopting the drilling and blasting method digging laneway, usually bore a kind of snubber of front (V face) oblique of and driving face parallel with horizontal plane (H face), this snubber is considered to the wedge shape eye.The method of known brill wedge shape eye is a direct jewel hole and do not adopt adjustable wedge shape eye guiding device.Depart from correct jewel hole direction easily owing to directly bore the wedge shape eye, so can cause blasting efficiency to be lowered.Also having a kind of way is the angle of directly measuring drill steel and driving face, also there are two problems in this kind way, the first amount of being difficult to gets angle accurately, and it two is to be difficult to guarantee that the wedge shape eye creeps into along correct direction, so also be difficult to obtain the demolition effect of expection.
Summary of the invention
In order to overcome existing shortcoming of boring the method for wedge shape eye, the utility model provides a kind of adjustable wedge shape eye guiding device, adopts this adjustable wedge shape eye guiding device can guarantee that jewel hole is in the right direction, and this is highly beneficial to the demolition effect of guaranteeing to obtain expection.
The technical scheme that its technical problem that solves the utility model adopts is: adjustable wedge shape eye guiding device mainly is made up of junction plate, guide pipe, spiral arm, protractor and screw.Pass through junction plate for the ease of drill bit and drill steel, in junction plate, be provided with mesopore.The junction plate base plane is a smooth plane.For the ease of unloading adjustable wedge shape eye guiding device, be provided with to unload on junction plate and guide pipe right-hand and put seam.Spiral arm rotates around screw and can make the guide pipe center line equate with the angle of driving face with the angle and the drill steel of junction plate base plane.Before headwork begins, the drill steel that designs in the angle furnishing of guide pipe center line in the adjustable wedge shape eye guiding device and junction plate base plane and the excavation operation rules is equated with the angle of driving face.When and drill steel parallel with driving face was placed in the guide pipe when the junction plate base plane, the guide pipe center line equated with the angle of driving face (V face) with the angle and the drill steel of junction plate base plane.Under the smooth condition of driving face (V face), manage to make the junction plate base plane parallel with driving face (V face), with drill bit and the drill steel guide pipe of packing into, treat that drill bit and drill steel enter the certain degree of depth of rock, after being determined, the jewel hole direction unloads adjustable wedge shape eye guiding device.
The angle of guide pipe center line and junction plate base plane can be conditioned in the adjustable wedge shape eye guiding device, so, adjustable wedge shape eye guiding device can adapt to the variation of the angle of drill steel and driving face, promptly when the angle of drill steel and driving face becomes big or diminishes, the guide pipe center line also can become greatly with the angle of junction plate base plane or diminish and the guide pipe center line is equated with the angle of driving face with the angle and the drill steel of junction plate base plane.
Adjustable wedge shape eye guiding device just can be obtained effect preferably under the smooth condition of driving face.
The beneficial effects of the utility model are, guarantee that jewel hole is in the right direction, for the demolition effect that obtains expection is taken a firm foundation, therefore, can improve blasting efficiency apparent in viewly and reduce explosive consumption.

As shown in Figure 1, guide pipe (7) is in the state of β=90 ° α=0 °. Screw (2) is in the state of being tightened. For the ease of Drill bit and drill steel are provided with mesopore (4) by connecting plate (1) in connecting plate (1). For the ease of unloading adjustable wedge-shaped hole Guider is provided with to unload on connecting plate (1) and guide pipe (7) right-hand and puts seam (6). Spiral arm (5) can be around screw (2) Rotate and reach the purpose of the angle of regulating guide pipe center line (11) and connecting plate base plane (8).
The specific embodiment
By wedge shape borehole arrangement diagram jewel hole shown in Figure 4, the angle of drill steel and driving face (13) is 65 °.
As shown in Figure 2, guide pipe (7) is in the state of β=90 ° α=0 °.Unclamp screw (2) earlier, make spiral arm (5) rotate 25 ° by counter clockwise direction then, tighten screw (2) then around screw (2).At this moment, guide pipe (7) is in the state of β=65 ° α=0 °, as shown in Figure 3.
Under the smooth condition of driving face (13), manage to make junction plate base plane (8) parallel with driving face (13), with drill bit and drill steel pack into guide pipe (7) and jewel hole forward, treat that drill bit and drill steel enter the certain degree of depth of rock, unload adjustable wedge shape eye guiding device after the jewel hole direction is determined.
