Description
Technical field
The utility model relates to underground coal mine protective device technical field, particularly relates to a kind of belt machine end guardrail.
Background technology
During the shipment transport of down-hole, often can shed broken coal and spoil, in order to keep the safety in production, need to arrange belt machine end guardrail, existing belt machine end guardrail is primarily of guardrail doorframe, guardrail dodge gate net, guardrail rack and locking limit switch composition, in use, because the gap between guardrail dodge gate net and guardrail doorframe is less, broken coal during shipment, spoil can often be stuck between guardrail dodge gate net and guardrail doorframe, very inconvenient when causing closing and open guardrail dodge gate net, workman is to the broken coal be stuck between guardrail dodge gate net and guardrail doorframe and spoil not easy cleaning simultaneously, waste time and energy.
Summary of the invention
The utility model object is to solve the aforementioned problems in the prior, provide a kind of structure simple, easy to operate, clean clean belt machine end guardrail.
The utility model is for achieving the above object, the technological means adopted is, a kind of belt machine end guardrail, comprise guardrail doorframe, the first dodge gate net, the second dodge gate net, guardrail rack and locking limit switch, divider gate frame bottom is fixedly connected with guardrail rack, guardrail doorframe inner bottom part is provided with the first slide bar and the second slide bar, first slide bar overcoat has multiple first movable slip ring, first movable slip ring is fixedly connected with the bottom of the first dodge gate net, second slide bar overcoat has multiple second movable slip ring, and the second movable slip ring is fixedly connected with the bottom of the second dodge gate net; The second online portion of dodge gate is provided with lockout contactor, and the guardrail doorframe outer upper near the second dodge gate net is provided with locking limit switch, and lockout contactor matches with locking limit switch.
Further, be provided with coal shovel bottom described first movable slip ring, the cross sectional shape of coal shovel is trapezoidal.
Further, be provided with bottom described second movable slip ring and sweep coal brush.
The utility model beneficial effect is: structure is simple, rationally novel in design, work as broken coal, spoil drops on guardrail doorframe, slide on the first slide bar by promoting the dynamic first movable slip ring of the first dodge gate guipure, promote the dynamic second movable slip ring of the second dodge gate guipure to slide on the second slide bar, first movable slip ring and the second movable slip ring are by broken coal, spoil is released from guardrail doorframe, breakdown of equipment when decreasing operation, again save manpower simultaneously, reduce the labour intensity of workmen, greatly reduce work capacity, thus improve work efficiency, guarantee safe production to greatest extent.
