Abstract

The utility model discloses a detonator protective device for disassembling a blasting charge. The detonator protective device comprises a shell, wherein the shell is made of elastic material, the outer surface of the shell is arc, the shell extends in the axial direction, one end of the shell has an end face composed of a plurality of triangular plates, and one edges of the triangular plates are sequentially connected. By means of the detonator protective device, after the charge is arranged inside a blasthole, the detonator protective device is pushed into the blasthole through a tamping bar to be tightly attached to the charge, and then filling and plugging are conducted. Under the pressure of plugging material, the arc shell produces deformation and is tightly contacted with the wall of the blasthole. Due to insulation of the triangular plates, when the plugging material is tamped through the tamping bar, a detonator leg wire will not be damaged, and a detonator is prevented from being separated from the charge after the plugging material presses an insulation pieces. The detonator protective device is simple in structure, low in cost, and convenient and reliable to use.

Description

A kind of detonator protective device of the demolition blasting blasting charge

Technical field

The utility model relates to a kind of detonator protective device of the demolition blasting blasting charge, belongs to the blasting engineering field.

Background technology

In the demolition blasting construction of buildings such as chimney, what mainly use is the horizontal shallow hole of 38 ~ 42 mm dias, the degree of depth is less than 1 meter, owing to being the reason that the lateral aperture degree of depth is little, the aperture is little, there are gap in packing and the upright opening of clogged with material such as employing clay, again because the demolition blasting dose is few, when carrying out powder charge obstruction work, because the operational negligence of workmen sometimes, the improper detonator that causes are pulled the blasting charge, can not primer when the result causes explosion and cause the big gun hole to be lost efficacy.For the demolition blasting of precision control, the existence of this problem gently then can influence the effect of demolition blasting, and is heavy then can cause demolition blasting failure even initiation security incident.Therefore, security and reliability for guaranteeing demolition blasting work are necessary to take measures to control the generation of the problems referred to above.

Summary of the invention

The utility model aims to provide a kind of detonator protective device of the demolition blasting blasting charge, and detonator is pulled out the blasting charge when guaranteeing effectively to avoid demolition blasting, can protect the detonator payment to a porter simultaneously.

For solving the problems of the technologies described above; the technical solution adopted in the utility model is: a kind of detonator protective device of the demolition blasting blasting charge; comprise that an outer surface of being made by elastomeric material is the housing of arc; housing extends vertically; end at housing has end face; described end face is made up of the plate of a plurality of triangles, one side the connecting in proper order of triangle plate.

Adopt said apparatus, in the big gun hole, pack into behind the blasting charge, this device pushed into the big gun hole with tamper be close to the blasting charge, carry out filler then and stop up, under the pressure of plugging material, the housing of arc produces deformation, and closely contact with the big gun hole wall, because the obstruct of triangle plate, with tamper tamping plugging material the time, can not damage the detonator payment to a porter, plugging material can stop that detonator is avulsed the blasting charge after pushing down plate.

The beneficial effects of the utility model are: simple in structure, with low cost, easy to use and reliable.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 assembles schematic diagram for the utility model in blast hole;

In the accompanying drawing: 1 housing, 2 plates, 3 detonators, 4 blastings charge, 5 detonator payment to a porter, 6 plugging materials.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further detailed.

As Fig. 1, Fig. 2, shown in Figure 3, the outer surface of housing 1 is arc, housing 1 extends vertically, housing 1 is equivalent to the part of body, and housing 1 usefulness synthetic rubber is made, and the wall thickness of housing 1 is 5 millimeters, housing 1 surface needs to make coarse, end at housing 1 has end face, and end face is made up of the plate 2 of three triangles, and the base of triangle plate connects in proper order.

During assembling, the blasting charge 4 usefulness tampers that at first will insert detonator 3 push into bottom, horizontal big gun hole, and wherein detonator 3 should be inserted in 4 times positions of the blasting charge; The utility model is pushed, and detonator payment to a porter 5 closely pastes plate 2 and the blasting charge 4 at housing 1 outer surface mutually, relaxes simultaneously in propelling movement and holds detonator payment to a porter 5; Push into clay and so on plugging material 6 and in addition tamping with tamper then; the open housing 1 of script this moment reaches closely knit with the big gun hole wall and contacts under plugging material 6 pressure effects; because the protective effect of housing 1; can not injure detonator payment to a porter 5 when stopping up operation; because the obstruct of plate 2 is protected, detonator 3 can not break away from the blasting charge 4 when stopping up again.

Claims

1. the detonator protective device of a demolition blasting blasting charge; it is characterized in that: comprise the housing (1) that an outer surface of being made by elastomeric material is arc; housing (1) extends vertically; end at housing (1) has end face; described end face is made up of the plate (2) of a plurality of triangles, triangle plate (2) one side connect in proper order.
