Description

A kind of steel wire preventer

Technical field

This utility model relates to a kind of steel wire preventer, belongs to blasting protection device field.

Background technology

At present, cannon is general by construction of prevention work application in next-door neighbour both wired, rural, street, national highway timber pile footpath caisson, city vertical shaft.This kind of method has the drawback that: cost is high, weight is relatively big, the lifting of additional mechanical machine-team, uses inconvenience, and affects the duration.

Summary of the invention

In order to reduce the cost of manufacture of cannon quilt, alleviate its weight, strengthen its relatively inexpensive property, shorten the construction period, this utility model adopts the following technical scheme that: a kind of steel wire preventer, has groups of springs and levels steel wire, and groups of springs is placed between levels steel wire, vertically the hoop cross winding of longitudinally, laterally going up of layer steel wire has string spring steel wire rope, and each point of intersection steel wire clamp is reinforced；It is wound with reinforcement steel wire rope in levels steel wire surrounding, strengthens steel wire rope and string spring steel wire rope at contact point with snapping connection.

The preventer of this structure, groups of springs available buffer explosion air pressure, string spring steel wire rope and reinforcement steel wire rope increase the intensity of steel wire preventer.Groups of springs arranges different density, can effectively prevent explosion stone and bulky grain dust excessive.

Further optimizing structure, string spring steel wire rope setting space in machine and transverse direction is 20 centimetres, and the spacing strengthening steel wire rope and string spring steel cable clamp junction point is 40 centimetres.This set, can the intensity of stiffened wire lath preventer, cost of manufacture can be saved again.

Further structure is arranged is that its end, corner is provided with lock ring, is so easy to the installation application of steel wire preventer, reduction of erection time.

Having reinforcement in end, steel wire corner along the interconnection of object line direction, the junction steel wire clamp at reinforcement with string spring steel wire rope is reinforced.This structure can make the intensity of steel wire preventer strengthen further.

The steel wire rope that string spring steel wire rope adopts diameter to be 8 millimeters, strengthens the steel wire rope that steel wire rope adopts diameter to be 16 millimeters.Such design can meet security application, again can effectively save cost resource.

The steel wire preventer adopting technique scheme has the advantages such as safe and environment-friendly, economic, practical.

Accompanying drawing explanation

Fig. 1 side view of the present utility model；

Fig. 2 plane graph of the present utility model；

Accompanying drawing is labeled as: 1 groups of springs, 2 upper strata steel wires, 3 lower floor's steel wires, 4 string spring steel wire ropes, 5 reinforcement steel wire rope, 6 reinforcements, 7 lock rings.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

This steel wire preventer, has groups of springs 1, upper strata steel wire 2 and lower floor's steel wire 3, and groups of springs 1 is placed between two-layer steel wire, and the junction of groups of springs and two-layer steel wire can take corresponding manner to fix.In the surrounding of levels steel wire, it is wound with the reinforcement steel wire rope 5 that diameter is 16 millimeters.

Steel wire and groups of springs are respectively provided with shock-absorbing function, can reduce resistance and the noise of shock wave, can stop when explosion and conscientiously play the effect of security protection by big finger stone.The difference of spring density in groups of springs 1, can produce different protection effects.Strengthen steel wire rope 5 and can strengthen the intensity of steel wire.

By groups of springs 1, levels steel wire 2,3, strengthen the outer layer of the cube structure that steel wire rope 5 is constituted, hoop cross winding is longitudinally, laterally carried out along steel wire with the string spring steel wire rope 4 that diameter is 8 millimeters, infall at string spring steel wire rope 4 is reinforced with dop, and the infall at string spring steel wire rope 4 and reinforcement steel wire rope 5 is reinforced the connection by buckle.

In order to save cost, and can guarantee that impact strength, string spring steel wire rope setting space in machine and transverse direction is 20 centimetres.For the best, the spacing that reinforcement steel wire rope 5 and string spring steel wire rope 4 snap connection is 40 centimetres is the best.

For the ease of lifting this steel wire preventer, at the corner place of steel wire all equipped with lock ring 7, this lock ring can be separately provided, and affixed with strengthening steel wire rope 5, it is possible to is integrally bent by reinforcement steel wire rope 5 and forms.

In order to increase the intensity of this steel wire preventer further, in diagonally connection strengthening rib 6, end, corner of steel wire.

This utility model is as follows at the installation method of demolition site: in the caisson fore shaft of construction to be blasted, pre-buried 4 to 6 diameters are the steel hoop of 20 millimeters, during blast working, manually by steel wire guard covers in aperture, steel hoop and lock ring 7 are attached with snap ring.

This utility model and common cannon by compared with, the input decreasing mechanical one-shift has saved work platforms, and is greatly saved cost, improves safety, and concrete Cost comparisons is as shown in the table:

Sequence number	Title	Weight (kg/㎡)	Unit price (unit/㎡)
				1	Cannon quilt	131.1	590
2	Steel wire preventer	5.3	105

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every equivalent structure utilizing this utility model description and accompanying drawing content to make is included in scope of patent protection of the present utility model.
