Description
Technical field
The utility model relates to coal mine total rock tunnelling field, especially a kind of coal mine roadway blows out waste rock blocking curtain.
Background technology
At present when coal mine roadway tunnels, most of using the method drilled and blasted, a large amount of cash can all be had every time by blowing out
Stone is dished out, and easily damages the metal mesh etc. of the circuit in tunnel, pipeline and construction site in this way, there is the protection using net formula at present
Structure, but some big spoils can only be blocked in this way, the small spoil of diameter can not be blocked, and fixed net is also required to expend
For a long time, this is existing deficiencies in the technology.
Invention content
The purpose of this utility model aiming at deficiency of the prior art, and provides a kind of coal mine roadway and blows out
Waste rock blocking curtain, the waste rock blocking curtain have hook that can be hung between, use easy to operation, and have gear cash body that can be compared entirely
The covering in face reduces the avalanche of spoil.
This programme is achieved by the following technical measures：A kind of coal mine roadway blows out waste rock blocking curtain, including gear cash body,
Multiple suppending holes are arranged in the top for keeping off cash body, be provided in suppending hole with the matched hook of suppending hole, in the both sides of gear cash body
Bottom is provided with multiple mounting holes, cover strip, the upper end of the cover strip and gear are both provided on mounting hole and suppending hole
Cash body is fixed.
The hook is S-shaped, a diameter of 6mm of hook.
The gear cash body is that belt keeps off cash body.It is provided with fixed strip above gear cash body, the suppending hole passes through
Fixed strip.
The height of the gear cash body is 100cm, and the width of gear cash body is 200cm.
The advantageous effect of this programme can according to the description of the above program, due to there is gear cash body can be in this scenario
Spoil is stopped, the avalanche of spoil is reduced；Suppending hole is arranged at the top of gear cash body, has hook to match use with suppending hole, this
Sample is convenient for suspension gear cash body, before blowing out, can be suspended on gear cash body on meeting head on so that gear cash body blocks borehole；In gear cash
The both sides and bottom of body are provided with multiple mounting holes, and scene is blown out what is met head on, whether will can keep off the four of cash body as needed
Week is fixed；It is both provided with cover strip on mounting hole and suppending hole, can prevent spoil from passing through mounting hole or suspension in this way
Hole avalanche；The upper end of cover strip is fixed with gear cash body rather than is all fixed, and is convenient for link up with across suppending hole in this way, or not
Fixed equipment pass through mounting hole, link up with as S-shaped, can be slid from hook to avoid gear cash body in this way；That links up with is a diameter of
6mm is convenient for gathering materials on the spot in this way, a diameter of 6mm reinforcing bars may be used and directly make；It is that belt keeps off cash body to keep off cash body, so both
It ensure that the intensity of gear cash body can stop cash body, it, can be with but also gear cash body has certain flexibility, and convenient for gathering materials on the spot
Use belt waste and old in tunnel；Fixed strip is provided with above gear cash body, suppending hole passes through fixed strip, is both convenient for hanging in this way
Hook passes through gear cash body and fixed strip, but also fold does not occur when gear cash body suspension, fixed strip also increases the intensity of gear cash body,
Hook is avoided to pull open suppending hole so that the situation that gear cash body falls off；The height for keeping off cash body is 100cm, and the width of gear cash body is
200cm is adapted to most borehole in this way.It can be seen that the utility model is compared with prior art, have substantive special
Point and progress, beneficial effects of its implementation are also obvious.
Description of the drawings
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Fig. 2 is the schematic diagram with hook.
In figure, 1 is gear cash body, and 2 be suppending hole, and 3 be mounting hole, and 4 be fixed strip, and 5 be cover strip, and 6 be hook.
Specific implementation mode
In order to clarify the technical characteristics of the invention, below by a specific implementation mode, and its attached drawing is combined, it is right
This programme is illustrated.
By attached drawing as can be seen that a kind of coal mine roadway of this programme blows out waste rock blocking curtain, including gear cash body 1, in gear cash body 1
Top multiple suppending holes 2 are set, be provided in suppending hole 2 with the matched hook 6 of suppending hole 2, the hook 6 is S-shaped,
A diameter of 6mm of hook 6.The both sides of gear cash body 1 and bottom are provided with multiple mounting holes 3, on mounting hole 3 and suppending hole 2
It is both provided with cover strip 5, upper end and the gear cash body 1 of the cover strip 5 are fixed.The height of the gear cash body 1 is 100cm, gear
The width of cash body 1 is 200cm.
The gear cash body 1 is that belt keeps off cash body.The top of gear cash body 1 is provided with fixed strip 4, the suppending hole 2
Across fixed strip 4.
