Abstract
The utility model discloses an energy-collecting boost tube, comprising a cylindrical tube body and a conical tube cap, wherein the tube cap is inserted into the tube body and fixed at the bottom of the tube body; an opening of the tube cap is downward; the outer diameter of the opening of the tube cap is the same as the inner diameter of the tube body; both of the tube body and the tube cap are made of steel plates; the tube cap is fixed on the tube body in a welding manner; two lifting holes are formed in the top part of the tube body; and a lifting rope is connected between the two lifting holes. The energy-collecting boost tube has the beneficial effects that the energy-collecting boost tube is simple in structure; a good blasting effect can be obtained, and the blasting amount of explosive charges is greatly improved; and the two lifting holes are formed in the top part of the tube body, the lifting rope is connected between the two lifting holes, and thus, the entire energy-collecting boost tube is conveniently put into the bottom of a blast hole.
Description
Technical field
The utility model relates to a kind of explosion servicing unit, particularly a kind of cumulative boost tube.
Background technology
At present, when carrying out blasting engineering, normally get several big gun holes with drilling tool, in the big gun hole, place detonator then and fill explosive, banket at the top in big gun hole again, ignite by the lead-in wire of detonator at last, but the burst size of this mode is limited, the explosion energy of explosive can not be brought into play fully.
Summary of the invention
Problem to be solved in the utility model is: the cumulative boost tube that a kind of simple in structure, burst size that can increase substantially explosive is provided.
In order to solve the problems of the technologies described above, cumulative boost tube of the present utility model comprises columned cylindrical shell and cone shape tube cap, and described tube cap is inserted in the cylindrical shell and is fixed on the bottom of cylindrical shell, Open Side Down for described tube cap, and the external diameter of the opening part of described tube cap is identical with the internal diameter of cylindrical shell.
Further, cumulative boost tube of the present utility model, described cylindrical shell and tube cap are made by steel plate, and described tube cap is fixed on the cylindrical shell by the mode of welding.
Carry out explosion for the ease of cylindrical shell being put into the big gun hole, the top of described cylindrical shell is provided with two lifting hole(eyelet)s, is to be connected to lifting rope between described two lifting hole(eyelet)s.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) the tube cap is inserted in the cylindrical shell and is fixed on the bottom of cylindrical shell, Open Side Down for described tube cap, in the time of explosion, cumulative boost tube is put into the bottom in big gun hole, in the big gun hole, fill explosive then, buried detonator, filled out tightly with soil at the top in big gun hole again, ignited by the lead-in wire of detonator at last, detonator, behind the explosive detonation, detonation product disperses along the direction of near normal big gun hole surface, when detonation wave advances to a tin cap, because a tube cap is coniform, its detonation product then flies out along the inner surface vertical direction of tube cap, speed equates owing to fly out, and explosive is distributed symmetrically, and detonation product accumulates on the axis of a cap, accumulate all very high air-flows of one speed and pressure, it has high speed, density, pressure and energy density, thereby can obtain better demolition effect, increase substantially the burst size of explosive; (3) top of cylindrical shell is provided with two lifting hole(eyelet)s, is to be connected to lifting rope between two lifting hole(eyelet)s, the convenient bottom of whole cumulative boost tube being put into the big gun hole.

Among the figure: 1, lifting rope, 2, lifting hole(eyelet), 3, cylindrical shell, 4, the tube cap, 5, the big gun hole, 6, explosive, 7, detonator, 8, lead-in wire, 9, soil.
The specific embodiment
As shown in Figure 1, cumulative boost tube of the present utility model comprises columned cylindrical shell 3 and cone shape tube cap 4, and described tube cap 4 is inserted in the cylindrical shell 3 and is fixed on the bottom of cylindrical shell 3, Open Side Down for described tube cap 4, and the external diameter of the opening part of described tube cap 4 is identical with the internal diameter of cylindrical shell 3; Described cylindrical shell 3 and tube cap 4 are made by steel plate, and described tube cap 4 is fixed on the cylindrical shell 3 by the mode of welding; The top of described cylindrical shell 3 is provided with two lifting hole(eyelet)s 2, is to be connected to lifting rope 1 between described two lifting hole(eyelet)s 2.
In the time of explosion, as shown in Figure 2, cumulative boost tube is put into the bottom in big gun hole 5, in big gun hole 5, fill explosive 6 then, buried detonator 7, fill out tightly with soil 9 at the top in big gun hole 5 again, ignite by the lead-in wire 8 of detonator 7 at last, after detonator 7, explosive 6 detonations, detonation product disperses along the direction on 5 surfaces, near normal big gun hole, when detonation wave advanced to a cap 4, because a tube cap 4 be coniform, its detonation product then flew out along the inner surface vertical direction of a cap 4.Speed equates owing to fly out, explosive 6 is distributed symmetrically, detonation product accumulates on the axis of a cap 4, accumulate all very high air-flows of one speed and pressure, it has high speed, density, pressure and energy density, thereby can obtain better demolition effect, increase substantially the burst size of explosive 6.
In addition, it is to be connected to lifting rope 1 that the top of cylindrical shell 3 is provided with between 2, two lifting hole(eyelet)s 2 of two lifting hole(eyelet)s, conveniently whole cumulative boost tube is put into the bottom in big gun hole 5, very easy to use.
