Summary of the invention
In order to prevent operating personnel Bu Zou People's Bank of China from passing a bridge, directly cross belt feeder tailstock, force operating personnel to walk People's Bank of China and pass a bridge on belt lane and help operation, and for adapting to this feature of belt feeder tailstock Autonomic Migration Framework.The invention provides a kind of girdle belt machine end safety device.
For solving the problems of the technologies described above, this girdle belt machine end safety device, it is characterized in that: comprise large grille guard and little grille guard, large grille guard and little grille guard form by rectangular frame and metal gauze, metal gauze is fixed on rectangular frame, on the front side wall of the rectangular frame of large grille guard, have slot, little grille guard stretches in slot, and can move forward and backward along slot.Described large grille guard is fixed on belt feeder tailstock, and described little grille guard is fixed on elevating conveyor.
So design, simple to operate, and installation once can be followed driving surface and be advanced together, has promoted safe mass Standardization Construction.Secondly; operating personnel's personal safety has been played to very large protective effect, eliminated operating personnel across belt feeder aircraft tail shelf break rules and regulations action, improved the automatization level of thin coal bed fully-mechanized mining face; embodied the design concept of hommization, active response build the call in harmonious mining area.In addition, processing and manufacturing is simple, and cost is low, and what fully demonstrated economize expense and reduce expend uses material theory.In addition, convenient and practical, there is very large promotional value.
As optimization, the rectangular frame of described large grille guard bottom is provided with inverted U-shaped draw-in groove, and this inverted U-shaped draw-in groove lower end is provided with folding pin, and described folding pin is provided with bolt hole.So design, can be installed on belt machine end shelf along upper by inverted U-shaped draw-in groove, is not affecting under the prerequisite of belt running, reduces, to the taking of space, footway, to have improved the carrying capacity on footway as far as possible.
As optimization, described little grille guard is provided with diagonal brace, and these diagonal brace two ends are separately fixed on the pair of horns that rectangular frame is relative.So design, is convenient to that the other end of guardrail is followed to the reach of elevating conveyor on belt feeder tailstock and the passing of belt feeder tailstock is free to slide.
As optimization, also comprise warning device, this warning device comprises lever, explosion-proof contact switch, buzzer phone and/or LED lamp, wherein lever and explosion-proof contact switch are fixed on large grille guard, and balance pivot is hinged, lever one end is over against the front end of explosion-proof contact switch, and the lever other end is connected with a stay cord, the stay cord other end is fixed on little grille guard, and explosion-proof contact switch, buzzer phone and/or LED lamp form alarm loop by wire.
So design, when stretching is straightened, lever touches the front end of explosion-proof contact switch, and while surpassing the distance of setting, buzzer phone is sounded or LED lamp lights, and reminds super distance, is convenient to safe in operation.
As optimization, also comprise warning device, this warning device comprises lever, explosion-proof contact switch, buzzer phone and/or LED lamp, wherein lever and explosion-proof contact switch are fixed on little grille guard, and balance pivot is hinged, lever one end is over against the front end of explosion-proof contact switch, and the lever other end is connected with a stay cord, the stay cord other end is fixed on large grille guard, and explosion-proof contact switch, buzzer phone and/or LED lamp form alarm loop by wire.
