Abstract
The utility model relates to an automatic car stopper of an underground mine inclined shaft. A frame is fixed to the top of an inclined shaft cylindrical wall, a rotating shaft is arranged at one end of the inner portion of the frame, one end of an oscillating rod is fixedly connected with one side of the rotating shaft, and the oscillating rod droops vertically through self weight. One end of a hanging ring rod is hinged to the other side of the rotating shaft, and a bend of the hanging ring rod is movably connected with a retaining ring in a sleeved mode. One end of a car stopping frame is hinged to a hinged shaft which is fixed to the top of the inclined shaft cylindrical wall, and a tensioning steel wire rope connected with the free end of the car stopping frame is connected with the retaining ring so as to lift the car stopping frame. When a traction steel wire rope is broken, a runaway mine car slides downwards in an accelerating mode to collide the oscillating rod, impact force is larger, the oscillating rod with increased oscillating amplitude rotates in an anticlockwise mode to impact the hanging ring rod, the retaining ring falls, and the tensioning steel wire rope connected with the retaining ring becomes loose. The free end of the car stopping frame lifted by the tensioning steel wire rope falls to a steel rail of the inclined shaft, and the mine car which slides downwards rapidly is stopped. Multiple sets of automatic car stoppers are installed along the inclined shaft so as to form an automatic inclined shaft car stopping system for mines, safety operation is guaranteed, and personnel and equipment accidents are avoided.
Description
Technical field
The utility model relates to a kind of underground mine safety device, particularly underground mine automatic tramcar stopper for inclined shaft.
Background technology
Stop buffer is mounted in underground mine inclined shaft middle and lower part, after preventing the disconnected rope of mine car or skip bucket, crashes into the inclined shaft bottom, causes personnel's injury and the damage of pit gear facility, to guarantee the safety of personnel and installations and facilities.Existing incline stop has hurdle net formula etc. multiple, but input cost is large, not too quick, poor sensitivity, and success ratio is lower.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of not manual operation, improves the underground mine automatic tramcar stopper for inclined shaft of inclined shaft operational security.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of underground mine automatic tramcar stopper for inclined shaft, and rectangular frame is fixed on inclined shaft barrel top, and the end in rectangular frame is provided with turning cylinder, one end of fork is fixedly connected with turning cylinder one side, and fork is vertical sagging by deadweight; One end of T-shaped link bar and the opposite side of turning cylinder are hinged, the elbow end of T-shaped link bar is shelved on the rectangular frame termination, the elbow and the clasp pivot bush unit that is positioned at below, rectangular frame termination of T-shaped link bar, the quarter butt at T-shaped link bar middle part is positioned at the frame of rectangular frame; Vehicle blocking frame is positioned at the descending orientation of rectangular frame along the inclined shaft barrel, one end of vehicle blocking frame is hinged with the jointed shaft that is fixed on inclined shaft barrel top, the tense wire rope be connected with the vehicle blocking frame free end is connected with described clasp through the pulley that is fixed on inclined shaft barrel top, the vehicle blocking frame position parallel with inclined shaft barrel end face of slinging.The spacing distance that above-mentioned underground mine automatic tramcar stopper for inclined shaft is installed along inclined shaft is 100--150 rice, and the underground mine automatic tramcar stopper for inclined shaft of installing forms mining inclined automatic car stopping system jointly.
During normal operation, mine car is hauled by traction winch and haulage cable, with safety speed V, along the rail of inclined shaft, transfers, and mine car is encountered fork, and impact is less, and the fork amplitude of oscillation is also less, and mine car passes through smoothly; When traction winch is out of control or the disconnected rope of haulage cable, when the speed that mine car out of control accelerates to glide is greater than 1.1 times of safety speed V, mine car is encountered fork, impact is larger, the fork left-hand revolution that the amplitude of oscillation increases strikes the quarter butt at T-shaped link bar middle part, jacking T-shaped link bar, come off with the clasp of T-shaped link bar elbow pivot bush unit, and the tense wire rope be connected with clasp is lax; Be tightened up the vehicle blocking frame free end that steel rope slings and fall on the rail of inclined shaft, block the mine car that top glides fast, avoid the generation accident.Described vehicle blocking frame and rectangular frame are 20--30 rice along the distance of inclined shaft barrel.
The beneficial effects of the utility model are: the not manual operation of this device, without power supply, be active in one's movements, easy for installation, simple and practical, be convenient to realize automation.Inclined shaft automatic car stopping system whole process realizes automatic car stopping, guarantees safe operation, avoids inclined shaft to slip car and crashes into inclined shaft bottom, causes personnel's injury and the damage of pit gear facility.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
