Description
Technical field
This utility model is related to a kind of large inclination working surface waste rock rolling prevention device.
Background technology
With the continuous developing of the new coal-face of coal mining enterprise, the high inclination-angle face of adopting continues to bring out, because inclination angle is big, plus
Work surface directly push up sand shale relatively broken it is easy to there is roof fall accident, therefore, ore deposit specifies the whole face frame upper berth gold that works
Belong to net shield top.
According to above-mentioned regulation, per tour operating personnel will frequently enter work surface and carry out the construction such as lapping networking, maintenance, and
Working face wall area wall caving rolls the personnel component security threat that cash enters work surface operation to lower section, for this problem, at present,
Wire netting or wire netting is taken to be protected in ore deposit, to prevent rolling cash from hurting sb.'s feelings, but this complex procedures, arduously time-consuming, seriously
Impact work surface production capacity plays.
Content of the invention
The problem existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of large inclination working surface anti-roll
Cash device, this device can effectively reduce the security risk of operating personnel, simple to operate, raising effect, mitigates the labor of operating personnel
Fatigue resistance.
For achieving the above object, this utility model provides a kind of large inclination working surface waste rock rolling prevention device, props up including being arranged on
Guide rod on frame back timber, the left end of guide rod is provided with fixed pulley, is provided with endless rope around fixed pulley, described endless rope is with fixed pulley institute
It is boundary in the vertical line of axis, be divided into top endless rope and bottom endless rope two parts；The lower section of guide rod is waste rock blocking curtain, described
Waste rock blocking curtain hang on guide rod by multiple suspension ring, the left end of bottom endless rope at junction point with positioned at the upper left of waste rock blocking curtain
The suspension ring at angle connect, and the lower end of waste rock blocking curtain arranges multiple hooks, and described suspension ring are enclosed within guide rod, under external force, can lead on edge
Bar slides.
In this technical scheme, multiple suspension ring that waste rock blocking curtain is passed through to slide on guide rod hang, and the upper left of waste rock blocking curtain
Angle is connected with endless rope, and endless rope is around on the fixed pulley of guide rod left end, and with the vertical line of fixed pulley place axle as boundary, point
For top endless rope and bottom endless rope, when pulling top endless rope, the left end of waste rock blocking curtain will drive in the presence of pulling force
Suspension ring are moved to the left along guide rod, and until reaching the high order end of guide rod, waste rock blocking curtain is fully expanded, and the hook of its lower end is hung over extension
On the chain of scratch board conveyor, between coal machine runway is to rib, define a closing protection network；When operation finishes, only need
The hook of lower end is unclamped from the chain of scratch board conveyor, pulls bottom endless rope, the left end of waste rock blocking curtain will be in pulling force
Effect is lower to drive suspension ring to move right along guide rod, and until reaching the low order end of guide rod, waste rock blocking curtain is packed up.Entirely close and packed up
Journey only needs one minute about, needs more than 15 minutes with respect to setting gear cash hurdle in former working procedure, when being effectively shortened operation
Between, improve work surface production capacity；This device need not be removed after a procedure, can move forward together with support, and its use also will not shadow
Ring the construction of other operations, reduce the labor intensity of operating personnel, and because personnel do not use working face wall area setting gear
Cash hurdle, therefore there is not rolling cash and the safety problem such as hurt sb.'s feelings, improve safety work coefficient.
In order to improve the tidiness of device, guide rod is set to hollow steel pipe, is easy to top endless rope and penetrates from the right side of guide rod
In guide rod, pass from guide rod left end and be around in fixed pulley.
Waste rock blocking curtain is wire side, in order to improve the serviceability of protection network, preferentially selects the big woollen goods of Wear-resistant corrosion-resistant toughness
Net makes.
For ensureing protection effect, the length of guide rod is coupled with the width that can roll cash at work surface scratch board conveyor.
For ensureing protection effect, the width of waste rock blocking curtain is identical with the length of guide rod, highly scrapes to work surface with set cap
The height coupling of plate transporter upper end.
