Abstract
The utility model relates to a rope breakage preventing device for the hoisting mechanism of a crane. The rope breakage preventing device comprises a bumper, a limit switch, hoisting capacity limiters, a wedge sleeve and a steel wire rope, and is characterized in that the rope breakage preventing device further comprises a T-shaped hanging board, wherein the T-shaped hanging board is inverted and hinged on the cross beam of a traveling car, the hoisting capacity limiters are symmetrically hinged with the two sides at the lower end of the T-shaped hanging board respectively, one end of the steel wire rope wounded on each hoisting capacity limiter is fixedly mounted on a hoisting winding drum, and the other end of each steel wire rope is fixedly mounted on the balance beam of a hoisting trolley. In the utility model, the principle of force balance is utilized, the T-shaped hanging board is designed, an original stress structure is reapportioned, the two steel wire ropes can bear load evenly, and in case of sudden breakage of one rope, the other rope also can bear the load and avoid the accident of weight falling. Therefore, the rope breakage preventing device has the advantages of double protections, compact structure and high safety performance, and ensures the safety performance during the operation of the hoisting mechanism of the crane.
Description
Technical field
The utility model belongs to hoisting crane and makes the art field, particularly relates to a kind of steel rope safety guard-safeguard aspect, can effectively guarantee the rope broken protector of the operating safe crane hoisting mechanism of hoisting crane work.
Background technology
At present, hoisting crane is widely used in fields such as Aeronautics and Astronautics, nuclear power, and steel rope has very important application as flexible member important in the hoisting crane in hoisting crane.Because the particularity of many working spaces for the purpose of safety guard-safeguard, forbids occurring unforeseen circumstancess such as wire cable rupture.So the rope broken protector of steel rope is installed very practical realistic meaning is arranged.
Summary of the invention
The utility model for the lifting mechanism that solves the technical matters that exists in the known technology and provide a kind of simple in structure, stable performance, assurance hoisting crane can safe operation the rope broken protector that is used for crane hoisting mechanism.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of rope broken protector that is used for crane hoisting mechanism; comprise the energy disperser that is installed on the travelling car crossbeam; be installed in the limit switch on the travelling car side plate; load lifting limiter; with load lifting limiter bonded assembly cover of wedge; and be wrapped in steel rope on the cover of wedge; it is characterized in that: described rope broken protector also comprises T shape link plate; on the T shape link plate handstand pivotally attached travelling car crossbeam; the both sides, lower end of described T shape link plate symmetry respectively are hinged with a load lifting limiter; a described end that is wrapped in the steel rope of each load lifting limiter is fixedly mounted on respectively on the hoisting drum, and the other end of steel rope is fixedly mounted on respectively on the equalizing bar of lifting dolly.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, changed the structure of original steel rope junction, promptly utilize the principle of a force balance, designed a T shape link plate, original force structure is redistributed, by two independently steel rope be wound between reel and this two groups of pulleys, one end of two steel ropes is fixed on the hoisting drum, the other end is separately fixed on the equalizing bar that is installed on the trolley frame, guarantee balancedly distribute loads of two steel ropes, another root still can maintain load when fracture suddenly wherein, can not cause the generation of weight fallen accident.Therefore the utlity model has duplicate protection, compact conformation, safety performance height, guarantee the safety performance that crane hoisting mechanism moves.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is that hoisting drum and steel rope connection structure scheme drawing Fig. 3 are the utility model running condition structural representations.
Among the figure: 1, travelling car crossbeam; 2, energy disperser; 3, travelling car side plate; 4, limit switch; 5, load lifting limiter; 6, cover of wedge; 7, steel rope; 8, T shape link plate; 9, hoisting drum.
The specific embodiment
For further understanding summary of the invention of the present utility model; characteristics and effect; now exemplify following examples; and conjunction with figs. is described in detail as follows: embodiment: see also Fig. 1 to Fig. 3; a kind of rope broken protector that is used for crane hoisting mechanism; comprise the energy disperser 2 that is installed on the travelling car crossbeam 1; be installed in the limit switch 4 on the travelling car side plate 3; load lifting limiter 5; with load lifting limiter 5 bonded assembly covers of wedge 6; and be wrapped in steel rope 7 on the cover of wedge 6; this rope broken protector also comprises T shape link plate 8; on the T shape link plate 8 handstand pivotally attached travelling car crossbeams 1; the both sides, lower end of described T shape link plate 8 symmetry respectively are hinged with a load lifting limiter 5; a described end that is wrapped in the steel rope 7 of each load lifting limiter 5 is fixedly mounted on respectively on the hoisting drum 9, and the other end of steel rope 7 is fixedly mounted on (not shown) on the equalizing bar that lifts by crane dolly respectively.
Principle of work: when hoisting heavy, gravity by wire rope transfers to cover of wedge 6, when wherein steel cable ruptures suddenly, T shape link plate will be done circular motion around hinge-point, when an end of T shape link plate touches limit switch, limit switch is transmitted to control system with shutdown signal, and this moment, control system was sent halt command; This moment, T shape link plate also continued motion, ran into energy disperser when the end of T shape link plate, and energy disperser will cushion its impulsive force that brings, and then its pipe protection effect, can not cause the generation of weight fallen accident, increase single-piece stability.
The utility model adopts technique scheme, changed the structure of original steel rope junction, promptly utilize the principle of a force balance, designed a T shape link plate, original force structure is redistributed, guarantee balancedly distribute loads of two steel ropes, another root still can maintain load when fracture suddenly wherein, can not cause the generation of weight fallen accident.Therefore the utlity model has duplicate protection, compact conformation, safety performance height, guarantee the safety performance that crane hoisting mechanism moves.
