Abstract

A novel blasting spacer comprises a bottom plate (1), a partition (2) and a lifting rope (4). The upper end of a support frame (3) is movably connected with the partition (2), the lower end of the support frame (3) is fixedly connected to the bottom plate (1), the lifting rope (4) is connected with the center of the partition (2), symmetrically distributed rib arms (5) are arranged on the lower surface of the partition (2), T-shaped grooves (6) are arranged on the outer edge of the partition (2), and T-shaped rubber sealing rings (7) are inserted into the T-shaped grooves (6), so that the sealing effect of the partition is improved, and the novel blasting spacer is simple in design and convenient to use.

Description

A kind of Novel explosion spacer

Technical field

The utility model belongs to the explosion field, relates to the spacer that a kind of explosion is used, and relates to especially a kind of spacer that utilizes rubber seal to improve sealing.

Background technology

The use of spacer can reduce even avoid the ore deposit rock impact comminution that forms because of coupling charging, enlarges the rupture zone scope, improves the effective rate of utilization of explosive blasting energy, thereby reduces explosive specific charge.Not only saved cost, and effectively improved the efficient of producing, for the good and fast development of mining activities provides effective approach.

But in the production application of reality, often there are all places of not complying with one's wishes in existing spacer.For example, by the spacer that dividing plate and the pillar that is connected with dividing plate consist of, put in use blast hole bottom, its shore supports is in the blast hole bottom surface, the dividing plate tabula in blast hole dynamite charge above dividing plate.But, because the shape of dividing plate is fixed, therefore can't tightly coincide with the shape of boring, and in order to put easily smoothly boring into, often size is less than boring, so sealing is poor, thereby affects demolition effect, moreover it is steady that the base that connects below pillar often can't be put owing to have water in the hole.

Moreover existing another spacer is referred to as gas spacer, often consisted of by two parts, a part is the air bag of an inflation, and another part is the device of inflation, in use, there is the device of inflation in air bag, to inflate, utilize the flexibility of air bag, fill boring, improve sealing effectiveness with this, but the use of this spacer, although effectively raise sealing effectiveness, because the explosion site operation is complicated, cause air bag to be scratched easily, therefore cost is higher, use inconvenience, in addition, owing to used special aerating device, so that the cost raising, and be with series of problems such as operating inconvenience.

Based on the problems referred to above, the utility model intends proposing a kind of Novel explosion spacer, on the basis of the advantage that absorbs existing spacer, solves the problem that existing spacer exists.

The utility model content

The application's technical problem to be solved:

The utility model is for the problem of the blasthole spacer existence of present use, and is poor such as sealing, uses inconvenient, a series of reasons of high in cost of production, a kind of Novel explosion spacer is proposed, on the basis of improving the separation seal effect, further simplify the operation, reduce cost.

The application is that the technical scheme that solves the problems of the technologies described above proposition is:

A kind of Novel explosion spacer, comprise base plate, dividing plate, the upper end of bracing frame and dividing plate are flexibly connected, and the lower end of bracing frame is fixedly connected on base plate, also comprises lifting rope, described lifting rope is connected with the center of dividing plate, the lower surface of dividing plate is provided with the rib arm that is symmetric, and the outward flange of dividing plate is provided with T-slot, and T shape rubber seal is inserted in the T-slot.

Further, for ease of grasping the down position of spacer, described lifting rope is provided with the scale label line.

Further, having under the environment of water to sink smoothly for making spacer, base plate is provided with leaking hole.

Further, described rib arm is 4.

Further, for improving the effect of sealing, the outward flange of described T shape rubber seal is zigzag.

The obtained beneficial effect of the application is:

The utility model arranges T-slot by the outward flange at dividing plate, and T shape rubber seal is inserted into wherein, has not only improved the sealing effectiveness of dividing plate, and simplicity of design, easy to use, and the design by leaking hole, so that the impact of ponding in when spacer sinks, avoiding being holed; Scale label line on the lifting rope can be used for determining the particular location that spacer descends.The utility model is easy to use, and cost is low, not only can improve blasting efficiency, and constructability.

Fig. 3 is the decomposing schematic representation of the utility model T shape rubber seal.

The specific embodiment

Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of Novel explosion spacer, comprise base plate 1, dividing plate 2, the upper end of bracing frame 3 and dividing plate 2 are flexibly connected, the lower end of bracing frame 3 is fixedly connected on base plate 1, also comprise lifting rope 4, described lifting rope 4 is connected with the center of dividing plate 2, and the lower surface of dividing plate 2 is provided with the rib arm 5 that is symmetric, the outward flange of dividing plate 2 is provided with T-slot 6, and T shape rubber seal 7 is inserted in the T-slot 6.By being arranged on the T shape rubber seal of separator edge, effectively raise the sealing effectiveness of spacer, overcome spacer since adopt rigidity dividing plate and can't with the tight shortcoming of coincideing of boring.

In addition, can grasp at any time the dropping distance of spacer for making spacer in the decline process, described lifting rope 4 is provided with the scale label line.

In practice, often can run into the situation that water is arranged in the boring, at this moment because base plate is enclosed, cause to sink owing to buoyancy of water, for solving this shortcoming, be provided with leaking hole 8 at base plate 1.When base plate 1 sank to the interface of water, ponding can enter into the spacer inner space by the leaking hole 8 that arranges on the base plate 1, so that spacer can continue to sink.

Simultaneously, rib arm 5 can be set to 4, and be that the outward flange of described T shape rubber seal 7 can be set to zigzag so that sinking is smooth.

Those skilled in the art is to be understood that; although the utility model is to be described according to the mode to individual embodiment; but getting specific embodiment in the specification only is for this utility model of clearer description; be not be used to limiting protection domain of the present utility model; any those skilled in the art; the equivalent variations of doing under the prerequisite that does not break away from design of the present utility model and principle, modification and combination all belong to the scope that the utility model is protected.
