Description
Technical field
The utility model relates to a kind of abat-vent of coal mine fully-mechanized mining working, relates in particular to a kind of face end support abat-vent.
Background technology
In process of coal mining, not cut apart as if not keeping out the wind between work plane and the old man's air, gas overflows the influence of work plane bigger.
In the prior art, face end support does not generally have abat-vent or use inconvenience, efficient is low, reliability is low etc., and most of mine is not installed abat-vent, and few part mine adopts the mode of iron wire kiss-coating plate to keep out the wind, and uses inconvenient, poor reliability.
Summary of the invention
The purpose of the utility model provides a kind of face end support abat-vent of simple in structure, easy to use, good reliability.
The purpose of the utility model realizes through following technical scheme:
The face end support abat-vent of the utility model; Comprise holder, fixed bar, said fixed bar and said holder are hinged, and said fixed bar is provided with chute; Be provided with little balladeur train in the said chute and pass frame; Be provided with the jack that keeps out the wind between said fixed bar and the said passing frame, said passing frame and little balladeur train are provided with the first fixing offset plate, and said fixed bar is provided with the second fixing offset plate.
Technical scheme by above-mentioned the utility model provides can be found out, the face end support abat-vent that the utility model provides is owing to comprise holder, fixed bar; Fixed bar and said holder are hinged; Fixed bar is provided with chute, is provided with little balladeur train in the chute and passes frame, is provided with the jack that keeps out the wind between fixed bar and the passing frame; Pass frame and little balladeur train and be provided with the first fixing offset plate, fixed bar is provided with the second fixing offset plate.First fixedly offset plate is can level flexible, and fixed bar can be around holder rotation, simple in structure, easy to use, good reliability.

The specific embodiment
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
The face end support abat-vent of the utility model, its preferable specific embodiment is as shown in Figure 1:
Comprise holder, fixed bar; Said fixed bar and said holder are hinged; Said fixed bar is provided with chute, is provided with little balladeur train in the said chute and passes frame, is provided with the jack that keeps out the wind between said fixed bar and the said passing frame; Said passing frame and little balladeur train are provided with the first fixing offset plate, and said fixed bar is provided with the second fixing offset plate.
Said holder is installed on the left side backplate of work plane left end head bracket and/or on the right side backplate of work plane right-hand member head bracket.
First fixedly offset plate is can level flexible, and fixed bar can be around holder rotation, simple in structure, easy to use, good reliability.Can be applicable to the downhole coal mine fully-mechanized mining working, be installed on the back timber or caving shield side guard board of end hydraulic support, in process of coal mining, be applicable to that end hydraulic support cuts apart work plane and old man's air, reduce gas and overflow influence work plane.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claims.
