Abstract
The utility model relates to an improvement of a lifting machine, in particular to a security mechanism lifting machine capable of preventing breakage of a steel wire rope, which has simple structure and is safe and reliable, and comprises four uprights among which a lifting platform is arranged, a beam the two ends of which are respectively provided with pulleys is respectively arranged at the two ends of the lifting platform, and the pulley is hung on the upright through the steel wire rope. The essential structure is that a fixed shaft is arranged at the side of the pulley of the beam, an eccentric wheel with lock teeth and a bracket is arranged on the fixed shaft, a shaft with a pinch roller is arranged on the bracket and is connected with the beam through a spring, and the pinch roller is pressed on the side of the upright of the steel wire rope by the steel wire rope. The lock sheet of a lockhole, which corresponds to the lock teeth, is arranged in the upright.
Description
Technical field:
The utility model relates to the improvement of lifting machine structure, relates in particular to a kind of lifting machine with safety gear of prevention wire cable rupture.
Background technology:
After the use of auto hoist through a period, steel rope can produce potential safety hazard.When the lifting platform lifting of lifting machine or when dropping to the optional position, if steel rope ruptures suddenly, lifting platform and can be thrown by the automobile of lifting causes automobile to damage and personal casualty.The lifting machine that has the congenerous safety gear in the past adopts the friction-type structure mostly, when the auto hoist wire cable rupture, its pinch roller loses support, and eccentric friction wheel is at the action of the spring lower swing, eccentric friction wheel off-centre wishes that to the jam plate sideway swivel frictionally stops lifting platform to be thrown.Because metal is harder, and jam plate surface spray paint, more sliding between eccentric friction wheel and the jam plate, can't pin the lifting platform of downslide, moreover everything takes place in moment all at all.Therefore,, perform practically no function, can't play real safety guard-safeguard effect at all although lifting machine in the past has this safeguard construction.
The utility model content:
The utility model is exactly at the problems referred to above, and a kind of simple in structure, safe and reliable lifting machine with the safety gear that prevents wire cable rupture is provided.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises four columns, between column, be provided with lifting platform, the lifting platform two ends are respectively arranged with the rollered crossbeam in two ends, pulley is hung on the column by steel rope, its structural feature is provided with anchor shaft in crossbeam top sheave side, anchor shaft is provided with the eccentric wheel with lock tooth and support, support is provided with the axle with pinch roller, axle links to each other with crossbeam by spring, and pinch roller is pressed in the stud sides of steel rope by steel rope; Be provided with the jam plate that has with the corresponding lockhole of lock tooth in the column.
The beneficial effects of the utility model:
Because the utility model is provided with anchor shaft in crossbeam top sheave side, anchor shaft is provided with the eccentric wheel with lock tooth and support, and support is provided with the axle with pinch roller, and axle links to each other with crossbeam by spring, and pinch roller is pressed in the stud sides of steel rope by steel rope; Be provided with the jam plate that has with the corresponding lockhole of lock tooth in the column; So simple in structure, be convenient to manufacture; When wire cable rupture, pinch roller loses the pressure of steel rope, has the effect by deadweight and spring of the eccentric wheel of locking tooth the lock tooth is locked in the lockhole of jam plate into, plays the effect of protection, and is safe and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a partial enlarged drawing of the present utility model;
Fig. 3 is a subelement structural representation of the present utility model.
The specific embodiment:
The utility model comprises four columns 5, between column 5, be provided with lifting platform 1, lifting platform 1 two ends are respectively arranged with the crossbeam 2 that two ends have pulley 3, pulley 3 is hung on the column 5 by steel rope 4, be provided with anchor shaft 11 in crossbeam 2 top sheaves 3 sides, anchor shaft 11 is provided with the eccentric wheel 9 with lock tooth 8 and support 14, and support 14 is provided with the axle 12 with pinch roller 13, axle 12 links to each other with crossbeam 2 by spring 10, and pinch roller 13 is pressed in column 5 sides of steel rope 4 by steel rope 4; Be provided with the jam plate 6 that has with lock tooth 8 corresponding lockholes 7 in the column 5.
Below in conjunction with description of drawings principle of work of the present utility model:
Normal when using the utility model, be installed in lifting platform 1 on the crossbeam 2 by steel rope 4 pull-ups, pinch roller 13 of the present utility model is pressed in column 5 sides of steel rope 4 by steel rope 4; At this moment, lock tooth 8 can not be inserted in the lockhole 7 of jam plate 6, but lifting platform 1 free lifting; When steel rope 4 breaks suddenly, steel rope 4 no longer bears pulling force, pinch roller 13 loses the pressure of steel rope 4, because spring 10 applies pulling force to pinch roller 13 all the time, pinch roller 13 is swung to a side under the effect of spring 10 pulling force and self gravitation, at this moment, lock tooth 8 on the eccentric wheel 9 inserts in the lockhole 7 of jam plate 6, lock tooth 8 rests on the jam plate 6, and lifting platform 1 stops to descend, and these actions all are to finish in the moment that steel rope 4 breaks.
