Abstract
The invention provides a lifting mechanism for an electromagnetic disc crane, relates to the electromagnetic disc crane, and solves the problem of complicated structure and large occupied space in the prior art. In the lifting mechanism, a lift motor is connected with a speed reducer through a floating shaft; the speed reducer is connected with a reel; the end parts of four steel wire ropes are respectively fixed on the reel by a steel wire rope pressure plate; every two steel wire ropes are symmetrically distributed, two vertical steel wire ropes are rolled symmetrically into the middle part of the reel, respectively bypass a deflecting pulley, a guide pulley and a vertical movable pulley, and are fixed on a balance arm to form two vertically symmetric hoisting points; and the two transverse steel wire ropes are respectively fixed by a steel wire rope pressure plate on the outer end of the reel, bypass from the same side of the two ends of the reel, go down directly to the two transverse movable pulleys, and bypass back to be fixed on the balance arm to form the other two transversely symmetric hoisting points. The lifting mechanism is applied to the electromagnetic disc crane, and has the advantages of simple structure, small occupied space, low manufacture cost, vertical and transverse swing prevention and the like.
Description
Technical field
The invention belongs to the handling machinery technical field, relate in particular to the in length and breadth lifting mechanism of two-way anti-sway, four-point lifting lifting of a kind of electromagnetic plate crane.
Background technology
Along with iron and steel enterprise to maximize, the development of high speed, the electromagnetic plate crane that is used for handling finished steel material is also just towards the future development of high-speed, high-level, high precision, Highgrade integration.This class electromagnetic plate crane is sling behind the steel material, by the rotating mechanism that lifting mechanism cooperates, realize to the stacking of steel material different azimuth with put.It requires in the rotating mechanism operational process, and hoisting mechanism steel wire rope can invar material centre-of gravity shift, and lack of equilibrium simultaneously, requires when the hoisting crane high-speed cruising, and suspender swings little.
The lifting mechanism of existing electromagnetic plate crane four-point lifting rotary hanger is two to overlap independently mechanism's co-operation, and suspension centre is 4 layouts of rectangle, in longitudinal and transverse two directions, and only can be anti-sway in a direction.Every cover independent agency is comprised of single motor, single reductor, single drum or single motor, single reductor, two reel.Every cover independent agency is responsible for hoisting of two suspension centres, and two overlap the method that independently adopts equalizer pulley or electrical control between the mechanism, realize the synchronous ascending of four-point lifting.The prior art complex structure takes up room larger.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, a kind of lifting mechanism of electromagnetic plate crane is provided, solves existing electromagnetic plate crane, adopt two cover independent agencies to realize the lifting mechanism of four-point lifting synchronous hoisting, have complex structure, large problem takes up room.
Technical scheme of the present invention is achieved in that
A kind of lifting mechanism of electromagnetic plate crane, comprise: lifting motor, reductor, reel, steel rope, it is characterized in that: described lifting motor is connected with the high speed shaft of described reductor by floating axle, the low speed axle head of described reductor is connected with described reel, there are four groups of steel rope pressing plates to fix respectively the end of four described steel ropes on the described reel, described steel rope is symmetrical in twos, along left-right rotary in four groovings that enter described reel, vertical two described steel rope symmetries are involved in described reel middle part, walk around respectively deflection sheave, leading sheave, vertical movable pulley, to equilibrium arm, fix, form two vertically symmetrical suspension centres; The described steel rope of horizontal two symmetries is then fixed by the described steel rope pressing plate of described reel outer end respectively, lay out from described reel two ends homonymy, directly lower two horizontal movable pulleys to the suspender lateral arrangement are fixing on the wraparound equilibrium arm again, form the suspension centre of two other lateral symmetry.
The present invention compared with prior art has the following advantages and beneficial effect:
Because the present invention hoists original dual-mechanism and changes the unit structure into and hoist; Changing original four-point lifting rectangular arrangement into the quadrature cross arranges, and provide the wirerope-winding method of quadrature cross four-point lifting lifting mechanism, therefore, the advantages such as that the present invention not only has is simple in structure, connection and reasonable arrangement, vehicle frame size are little, occupy little space, low cost of manufacture, and can realize two-way anti-sway in length and breadth.Simultaneously, wirerope-winding method of the present invention, in the time of can guaranteeing that any steel cable disconnects, institute's object that hangs can run-off the straight or fallen, and is safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present invention (front view);
Fig. 2 is the label of the birds-eye view of Fig. 1.
Be elaborated with regard to the specific embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, 2, a kind of lifting mechanism of electromagnetic plate crane is comprised of lifting motor 1, floating axle 2, reductor 3, reel 4, steel rope pressing plate 5, deflection sheave 6, leading sheave 7, vertical movable pulley 8-1, horizontal movable pulley 8-2, drg 9, steel rope 10, equilibrium arm 11, vehicle frame 12.Described lifting motor 1 is connected with the high speed shaft of reductor 3 by floating axle 2, the low speed axle head of reductor 3 is connected with reel 4, there are four groups of steel rope pressing plates 5 to fix respectively the end of four steel ropes 10 on the reel 4, steel rope 10 is symmetrical in twos, along left-right rotary in four groovings that enter reel 4, vertical two steel rope 10 symmetries are involved in reel 4 middle parts, walk around respectively deflection sheave 6, leading sheave 7, vertical movable pulley 8-1, to equilibrium arm 11, fix, form two vertically symmetrical suspension centres; 10 of the steel ropes of horizontal two symmetries are fixing by the steel rope pressing plate 5 of reel outer end respectively, lay out from reel 4 two ends homonymies, directly lower two horizontal movable pulley 8-2 to the suspender lateral arrangement are fixing on the wraparound equilibrium arm 11 again, form the suspension centre of two other lateral symmetry.
Wirerope-winding mode of the present invention, when having realized that any steel cable disconnects, institute's steel material that hangs can run-off the straight or is fallen, and safety is further enhanced.
