Description
Technical field
The utility model relates to a kind of suspender detecting device, and in particular, the utility model is about suspension conveyer chain suspender unhook detecting device.
Background technology
In the suspension conveyer chain suspender, because of suspender when the conversion of two serobilas, can occur that two kinds of strange phenomena: a, two serobilas are asynchronous to cause that cutting somebody's hair of tow chain is not meshing causes the suspender unhook in the groove of hoisting tool bogie lifting pawl, the suspender after the unhook can pushed away by the suspender of back and move; B, suspender when long-pending putting before and after dolly be snapped under together the situation, enter into two serobila switch sites simultaneously, cutting somebody's hair of tow chain just can't be hung in the groove of hoisting tool bogie lifting pawl, can only collude the rear portion at hoisting tool bogie; When above-mentioned two kinds of situations occurring, suspender the coaster phenomenon can occur when running to the lower slope section of suspended chain.Therefore the generation that a kind of device can detect above-mentioned two kinds of situations automatically need be set, and can shut down by the automatic guidance suspender, send warning reminding operating personal trouble-shooting simultaneously.
Patent Office of the People's Republic of China has announced a CN201074123Y document on June 18th, 2008, name is called a kind of Stacking Type Hang Conveyer suspender lifting pawl uplifting device, this device comprises presses the rail district, lifts the rail district, changes sequence and change chain area carrier rail, is provided with and changes the sequence gradient on the chain area carrier rail and force plate accordingly changing; The pressure plate is a wedge shape; The advantage of this device is can effectively solve in the mechanization free parking type stretched wire delivery system, utilize stretched wire to cut somebody's hair and drive the preceding dolly lifting pawl transmission of suspender, through by press rail to lift rail change chain the time, in case jam appears in preceding dolly, will cause the unhook of cutting somebody's hair of lifting pawl and stretched wire, suspender is out of service, thereby causes influence to be produced, even technical matters such as safety misadventure takes place.The shortcoming of this device is to adopt the method for machinery to solve the problems referred to above structure more complicated, do not have the auto alarm function.
Summary of the invention
The electric method of the utility model employing has solved existing complicated in mechanical structure, has not had the technical matters of auto alarm function; a kind of suspension conveyer chain suspender unhook detecting device is provided; the detection of energy automatic fault, automatic guidance suspender are shut down when unhook or interlock take place suspender, send warning reminding operating personal trouble-shooting simultaneously.
