Abstract
A kind of mine cage chair and safety door linkage, relate to a kind of control cage chair lifting of the safety precaution for vertical shaft for mine well head and the linkage of safety door opening and closing.It is characterized in that its structure comprises: the upper track adjusting wheel being arranged on well head column top; Be arranged on the middle leading sheave in the middle part of well head column; After being arranged on the middle leading sheave guiding in the middle part of well head column, upwards, with upper track adjusting wheel overlap the movable pulley rope coordinated along well head column; One end is fixed in the middle part of well head column, along well head column upwards, to overlap with movable pulley and coordinate, the safety door rope that the other end connects with safety door upper end after movable pulley.Device of the present utility model, the interlock of opening safety door simultaneously when can effectively realize cage chair, when cage chair rises, safety door blocks well head personnel and vehicle by deadweight along slideway decline, the interlock of closed safe door while of when realizing rising cage chair, simple to operate, easy to use, safe and reliable, effectively can improve work efficiency.
Description
Technical field
A kind of mine cage chair and safety door linkage, relate to a kind of control cage chair lifting of the safety precaution for vertical shaft for mine well head and the linkage of safety door opening and closing.
Background technology
At present, conventional cage chair lifting or safety door opening and closing all adopt two cover powered actuation mechanism (as: two cover oil cylinders), during this constructional device operation, need to carry out difference twice operation and perform lifting cage chair or opening and closing safety door, but must operation order be ensured, that is: first fall cage chair, open safety door again, or first close safety door, then rise cage chair, a circulation must operate 4 times and complete; Otherwise will break down or accident.And two covers powered actuation mechanism (as: two cover oil cylinder), the problems such as the higher and maintenance capacity of fault rate is larger.Not only complicated operation is loaded down with trivial details, and operating efficiency is also low, more can affect the safety of shaft mouth operation personnel.
Utility model content
It is simple, safe and reliable that the purpose of this utility model is to provide a kind of operation, the cage chair that efficiency is high and safety door linkage.
For achieving the above object, the utility model takes following technical scheme.
A kind of mine cage chair and safety door linkage, is characterized in that its structure comprises:
Upper track adjusting wheel, on this, leading sheave is arranged on well head column top;
Middle leading sheave, this middle leading sheave is arranged in the middle part of well head column;
Movable pulley rope, one end of this rope is fixed on mine cage chair, after being arranged on the middle leading sheave guiding in the middle part of well head column, along well head column upwards, to overlap with upper track adjusting wheel and coordinate, the other end is connected with a movable pulley through the backward lower hanging of upper track adjusting wheel;
Safety door rope, one end of this rope is fixed in the middle part of well head column, along well head column upwards, the movable pulley affixed with movable pulley rope overlap and coordinate, the other end connects with safety door upper end after movable pulley.
A kind of mine cage chair of the present utility model and safety door linkage, the interlock of opening safety door simultaneously when can effectively realize cage chair, when cage chair rises, safety door blocks well head personnel and vehicle by deadweight along slideway decline, the interlock of closed safe door while of when realizing rising cage chair, its method is simple to operate, easy to use, safe and reliable, effectively improve work efficiency, efficiency improves 50%, reduces costs, and reduces maintenance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing thereof, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
A kind of mine cage chair and safety door linkage, its structure comprises:
Upper track adjusting wheel 1, on this, leading sheave is arranged on well head column 3 top;
Middle leading sheave 4, this middle leading sheave is arranged in the middle part of well head column;
Movable pulley rope 2, one end of this rope is fixed on mine cage chair 8, after being arranged on the middle leading sheave guiding in the middle part of well head column, along well head column upwards, to overlap with upper track adjusting wheel and coordinate, the other end is connected with a movable pulley 6 through the backward lower hanging of upper track adjusting wheel;
Safety door rope 7, one end of this rope is fixed in the middle part of well head column, along well head column upwards, the movable pulley affixed with movable pulley rope overlap and coordinate, the other end connects with safety door 5 upper end after movable pulley.
A kind of mine cage chair of the present utility model and safety door linkage, drive movable pulley rope when cage chair falls, and makes movable pulley increase by safety door rope drive safety gate along slideway (or track) 9 rising (safety door rises-opens); When cage chair rises, movable pulley rope reclaims, movable pulley pulls safety door rope movable pulley is declined and strains movable pulley rope under the Action of Gravity Field of safety gate, simultaneously safety gate drops to assigned position (desired location) along slideway (or track) and plays closing function (avoid pedestrian, vehicle enter), the interlock of opening safety door simultaneously when achieving cage chair, when cage chair rises, safety door blocks well head personnel and vehicle by deadweight along slideway decline, the interlock of closed safe door while of when realizing rising cage chair.
