Abstract
The utility model provides an underground coal mine coal bunker upper opening safety device which solves the problems that in the process of operation of a prior coal bunker, coal water leakage, blocking of the coal bunker and personal casualty are easy to happen. The underground coal mine coal bunker upper opening safety device comprises a waterproof ring fixed on an upper opening of the coal bunker and a supporting steel girder placed in the waterproof ring. A machine frame is connected with the supporting steel girder. A rail is fixed on an upper end face of the machine frame. A movable trolley capable of sliding forwards and backwards along the rail is arranged on the rail. A guardrail is laid on the periphery of the machine frame. A latticed separating frame is arranged in the middle portion of the machine frame. A coal storing hole is formed in the middle of the separating frame. The rear end of the movable trolley is connected with an electric-hydraulic pusher, wherein the other end of the electric-hydraulic pusher is connected with the machine frame. The underground coal mine coal bunker upper opening safety device has the advantages of being reasonable and reliable in design structure, capable of preventing water from running in a tunnel and big stones and long materials in coal flow from entering into the coal bunker and guaranteeing safety of operators on the coal bunker upper opening and people passing by, flexible in action, easy to maintain, convenient to operate and capable of being widely used by underground coal mine vertical coal bunkers and underground coal mine inclined coal bunkers.
Description
Technical field
The utility model relates to the colliery safety device, is specially a kind of coal mine bunker safety device suitable for reading.
Background technology
Coal mine bunker is in the intermediate link of underground hauling of coal system.Its one one of suitable for reading general installation or multi-section rubber conveyer, end opening is installed feeder.Advance in the process of coal and coal storage at coal bunker, often have flowing water, boulder and surplus material and follow coal to enter.Flowing water has accumulated many can cause the water coal to burst let out.Boulder and surplus material can cause coal bunker blocking.In addition, coal bunker is suitable for reading also to be the place in personnel's operation or path, if any accidentally, can cause personnel to be strayed into and cause casualty accident.
Summary of the invention
The utility model easily causes the water coal to burst when solving existing coal bunker operation and lets out, the problem of coal bunker blocking and casualties, provides a kind of coal mine bunker safety device suitable for reading.
The utility model is to adopt following technical scheme to realize: coal mine bunker safety device suitable for reading, comprise the support steel beam that is fixed on coal bunker water proof ring suitable for reading and is positioned at water proof ring, be connected with frame on the support steel beam, the frame upper surface is fixed with track, be provided with the billy gate that slides along its front and back on the track, be laid with guardrail around the frame, and central rack is provided with latticed insulating frame, the insulating frame middle part has puts the coal hole, and the rear end of billy gate is connected with the Electrohydraulic push rod that the other end is connected with frame.
Before the conveyor running, by Electrohydraulic push rod billy gate is adjusted to the appropriate location, generally leave 100 ~ 200 millimeters of unloading coal flow horizontal distances, as want to catch boulder and the long-object of sneaking in the coal stream, should make the billy gate front end as far as possible near coal stream, and billy gate reliably braked, larger inertia and the large-size that can utilize big article to have are caught it, prevent that big article from entering coal bunker; When conveyor shutdown, maintenance and no-load running, billy gate is pushed into the unloading roller lower end, billy gate all seals the coal bunker mouth with insulating frame.Easily cause the water coal to burst when having overcome existing coal bunker operation to let out, the problem of coal bunker blocking and casualties.
Be connected with the control valve that is installed on the conveyor driver console on the Electrohydraulic push rod; the action that realizes conveyor and billy gate is chain, and namely when conveyor was shut down, billy gate automatically reach cut out the coal bunker coal unloading hole; before the conveyor start, billy gate automatically moves back opens the coal bunker coal unloading hole.
The quantity of billy gate is two, and the position of billy gate is corresponding up and down with the conveyor of its top, and two billy gates distribute up and down, is applied to same coal bunker two conveyors and the situation of layout in opposite directions of installing simultaneously suitable for reading.
The utility model reasonable in design is reliable, can prevent that boulder and surplus material enter coal bunker in tunnel flowing water, the coal stream; Guaranteed coal bunker operating personnel suitable for reading and holdee's safety; Have flexible movements, safeguard simple, easy to operate advantage, be widely used in vertical coal bunker and down-hole tilt coal bunker under the coal mine.
