Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
The purpose of this utility model is to provide a kind of individual flying protective devices of explosion, to improve the safety of blasting process
Property and high efficiency, meanwhile, reduce blasting dust.
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, below in conjunction with the accompanying drawings and have
Body embodiment is described in further detail the utility model.
Embodiment 1,
As shown in Figure 1, the present embodiment provides a kind of individual flying protective devices of explosion, it is mounted on cuboid column
On, including the first frame 1, the second frame 2, the first protection network 3 and the second protection network 4.
Four the first frames 1 are set on four sides of column, and the first protection network 3 is wound in first in one or more layers
The outside of frame 1 makes the first protection network 3 be close to column.Second protection network 4 is set in the second frame 2, the second frame 2 and
The quantity of one frame 1 is identical, and the second frame 2 fits with the first frame 1, and the second frame 2 is solid by fastener and the first frame 1
Fixed connection, fastener pass through the mesh of the first protection network 3.It is connected by connector 5 between the second adjacent frame 2, first is anti-
There are gaps between protecting wire net 3 and the second protection network 4.
First protection network 3 is protection network made of the materials such as flexible net, such as polyethylene, polypropylene.The net of this material
Line is flexible deformation in certain range of stretch, but will be broken when level of stretch is more than certain proportion.Due to exploding
In the process, the stressing conditions of the first protection network 3 are complex, can not both ensure uniform force everywhere in the first protection network 3, also without
Method ensures that the mechanical property at each position of the first protection network 3 is consistent.Therefore, if simple take winds the on column
The mode of one protection network 3 carries out blasting protection, it is difficult to guarantee safety.
In the present embodiment, due to the fixation of fastener, the part on four the first frames 1 is the first protection network 3
Tensioning state, and four sides are independent of each other.Even if breakage occurs for the part of some side, the power of other parts will not be influenced
Learn performance.
Since there are gaps between the first protection network 3 and the second protection network 4, when the first protection network 3 is not enough to block stone,
First protection network 3 ruptures.First protection network 3 drawn certain length at this time, stone by first protection network 3 obstruction its
Kinetic energy has reduced a part, is then stopped by the second protection network 4.The gap of first protection network 3 and the second protection network 4
It is to reserve certain stretching distance to the first protection network 3, the specific size in the gap can be according to the material of the first protection network 3
Deformation limit set so that the first protection network 3 on four sides of column can play maximum effect.If be not desired to
First protection network 3 is damaged, also can suitably reduce the gap, to make the first protection network 3 reuse.At this point, the first protection network 3
It mainly works as a buffer, dominating impact is undertaken by the second protection network 4.Second protection network 4 is chosen as flexible net, is also chosen as metal
Net, it is generally the case that the second protection network 4 is better than the mechanical property of the first protection network 3.
Water bag 6 is provided between first protection network 3 and the second protection network 4, water bag 6 is hung on the second protection network 4.When first
When protection network 3 absorbs impact, water bag 6 both can play a buffer role in, and water bag 6 can prevent dust loss again after rupture, to keep away
Exempt from the pollution to environment.
The protective capacities at four angles in order to improve column prevents stone between the gap of the first frame 1 and second
It flies out between the gap of frame 2, the present embodiment is additionally provided with third protection network (being not drawn into figure).Distinguish at the both ends of third protection network
It is fixed on the outer surface of two neighboring second frame 2, to which the first protection network 3 at the gap of adjacent first frame 1 is damaged
After carry out secondary protection.
In addition to the part in the second frame 2, that is, the first protection network 3 and the second protection network 4 that are fixed on the second frame 2 are wanted
Outside absorbing impact, the connector 5 for connecting adjacent second frame 2 will also absorb impact.It is adjacent in order to improve overall security
The first frame 1 between also can by connector 5 be connected.
In the present embodiment, connector 5 selects elastic material, such as rubber strip, those skilled in the art that other materials also can be selected
Material, such as wire.
Embodiment 2,
The present embodiment provides a kind of individual flying protective devices of explosion, are mounted on cuboid column.Its structure with
The structure of embodiment 1 is substantially the same, and is the first frame 1, the first protection network 3, water bag 6 from inside to outside and is equipped with the second protection
Second frame 2 of net 4.Difference lies in, since the shape of column is different, as the first frame 1 being bonded with it and with the first frame
The shape for the second frame 2 that frame 1 is bonded also is changed accordingly.
As shown in Fig. 2, the first frame 1 and the second frame 2 are by two semicircles of two half-round bars disposed in parallel and connection
The support bar group of bar is at the first frame 1 and the second frame 2 are two.The first adjacent frame 1 is connected by connector 5, phase
The second adjacent frame 2 is connected by connector 5.
It applies specific case in this specification to be expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model；Meanwhile for the general of this field
Technical staff, according to the thought of the utility model, there will be changes in the specific implementation manner and application range.To sum up institute
It states, the content of the present specification should not be construed as a limitation of the present invention.
