Abstract
The utility model provides a spacer of a blast hole. The spacer comprises a base (1), a partition plate (2) and a supporting column (3). The upper end of the supporting column (3) is hinged to the partition plate (2), the lower end of the supporting column (3) is fixedly connected with the base (1), and rib arms (4) are symmetrically arranged on the lower surface of the partition plate (2). The spacer further comprises a flexible air bag (5), the flexible air bag (5) uses the supporting column (3) as the center and is filled between the base (1) and the partition plate (2), and one end of an air inlet pipe (6) penetrates through the partition plate (2) to be connected with the flexible air bag (5). The flexible air bag is arranged between the base and the partition plate, and sealing performance between the partition plate and a hole is improved. After the flexible air bag is inflated, the whole hole is filled by the flexible air bag, and the sealing performance is improved.
Description
Technical field
The utility model relates to a kind of demolition set, particularly relates to a kind of blasthole spacer, and this spacer can be in order to improve the flexible airbag of sealing effectiveness with one.
Background technology
In blast working, the particularly deep hole blasting in the surface mine blasting engineering, and blasthole diameter more than 90 millimeters, deep hole is more than 10 meters, will use the spacer technology, can adopt bottom or interval, middle part, this mode reduces explosive specific charge, damping waterproof, the foundation that reduces; Reduce big gun hole implode pressure, the ore deposit rock impact comminution that reduces even avoid forming because of coupling charging enlarges the rupture zone scope, improves the effective rate of utilization of explosive blasting energy, thereby reduces explosive specific charge.In addition, because improve the powder charge position, make implode pressure in hole more even along the axial distribution in big gun hole, can effectively overcome foundation and reduce the explosion boulder yield, for the subsequent handlings such as shovel dress create favorable conditions.
Existing spacer is made of with the pillar that is connected with dividing plate dividing plate usually, puts in use blast hole bottom, and its shore supports is in the blast hole bottom surface, the dividing plate tabula in blast hole dynamite charge above dividing plate.But, there are some problems in existing spacer, for example, because the shape of dividing plate is fixed, therefore can't be very identical with the shape of boring, thereby therefore owing to the poor demolition effect that affects of sealing, moreover it is steady that the base that connects below pillar often can't be put owing to have water in the hole.
For above-mentioned technical problem, although gas spacer has been arranged now, this gas spacer uses and is inconvenient, and because flexible, effect is also bad, therefore also can't be widely used.
Based on the problems referred to above, the utility model intends proposing a kind of new-type blasthole spacer, in conjunction with the advantage of existing blast hole, solves the problem that existing spacer exists.
The utility model content
The application's technical problem to be solved:
The problem that the utility model exists for existing blasthole spacer, poor such as sealing, impact effect, gas spacer uses a series of reasons such as inconvenient, propose a kind of new blasthole spacer, not only improved the sealing of existing spacer, and easy to use.
The application is that the technical scheme that solves the problems of the technologies described above proposition is:
A kind of blasthole spacer, comprise base, dividing plate, support column, described support column upper end is articulated in dividing plate, the lower end is fixedly connected on base, the lower surface of described dividing plate is provided with the rib arm that is symmetric, and also comprises flexible airbag, and described flexible airbag is centered by support column, be filled between base and the dividing plate, an end of air inlet pipe passes dividing plate and is connected with flexible airbag.
Further, be the ability that the integral body that improves dividing plate withstands shocks, the angle of described rib arm and support column is 60 degree.
Further, for avoiding ponding in the hole, make that base puts steadily, base is provided with leaking hole.
Further, for ease of using, described air inlet pipe is flexible air inlet pipe.
Further, the other end of described air inlet pipe is provided with stop valve.
The obtained beneficial effect of the application is:
The utility model adopts the mode that flexible airbag is set between base and dividing plate, improve the sealing between dividing plate and the hole, and after flexible airbag inflation, flexible airbag can tightly be full of in the whole hole, has therefore just improved sealing property.Owing to have leaking hole at base, therefore when blasthole spacer is put into boring, even water is arranged in the hole, can not have influence on the steady of spacer simultaneously yet.
Description of drawings
Structure chart when Fig. 1 is the flexible airbag unaerated of the utility model;
Structure chart when Fig. 2 is the flexible airbag inflation of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of blasthole spacer comprises base 1, dividing plate 2, support column 3, described support column 3 upper ends are articulated in dividing plate 2, and the lower end is fixedly connected on base 1, and the lower surface of described dividing plate 2 is provided with the rib arm 4 that is symmetric, also comprise flexible airbag 5, described flexible airbag 5 is filled between base 1 and the dividing plate 2 centered by support column 3, and an end of air inlet pipe 6 passes dividing plate 2 and is connected with flexible airbag 5.
For further improving the ability that dividing plate 2 withstands shocks, described rib arm 4 can be set to 60 degree with the angle of support column 3.Owing in boring, often having ponding, therefore be provided with leaking hole 7 at base 1, when blasthole spacer was put into boring, the ponding in the hole will get the leaking hole 7 from base 1 and flow out, and can not affect the steady of spacer.
For the ease of using, described air inlet pipe 6 can adopt flexible air inlet pipe, and can be provided with stop valve 8 at the other end of air inlet pipe 6, and after inflation is finished, thereby stop valve 8 will self-closed be finished the interval in hole.
The utility model adopts the mode that flexible airbag is set between base and dividing plate, improve the sealing between dividing plate and the hole, and after flexible airbag inflation, flexible airbag can tightly be full of in the whole hole, has therefore just improved sealing property.Owing to have leaking hole at base, therefore when blasthole spacer is put into boring, even water is arranged in the hole, can not have influence on the steady of spacer simultaneously yet.
