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 lifting mechanism of two-way in length and breadth anti-sway, the four-point lifting lifting of a kind of electromagnetic disc hoisting crane.
Background technology
Along with the development of iron and steel enterprise to maximization, high speed, the electromagnetic disc hoisting crane that is used for handling finished steel material also just develops towards the direction of high-speed, high-level, high precision, Highgrade integration.This class electromagnetic disc hoisting 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 the lifting mechanism steel rope can invar material centre-of gravity shift, and lack of equilibrium simultaneously, requires when the hoisting crane high-speed cruising, and the suspender swing is little.
The lifting mechanism of existing electromagnetic disc hoisting 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 made up 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 hoisting synchronously of four-point lifting.The prior art complex structure, it is bigger to take up room.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of lifting mechanism of electromagnetic disc hoisting crane is provided, solves existing electromagnetic disc hoisting crane, adopt two cover independent agencies to realize the four-point lifting lifting mechanism of lifting synchronously, have complex structure, big problem takes up room.
Technical scheme of the present invention is achieved in that
A kind of lifting mechanism of electromagnetic disc hoisting 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 the end of four described steel ropes respectively on the described reel, described steel rope is symmetrically distributed in twos, along left and right sides rotation direction in four groovings of going into described reel, vertical two described steel rope symmetries are involved in described reel middle part, walk around deflection sheave respectively, leading sheave, vertical movable pulley, to equilibrium arm, fix, form vertically two suspension centres of symmetry; 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, fix on the wraparound equilibrium arm again, form the suspension centre of two other lateral symmetry down to two horizontal movable pulleys of suspender lateral arrangement.
The present invention compared with prior art has the following advantages and beneficial effect:
Because the present invention hoists original two-shipper structure and changes the unit structure into and hoist; Changing original four-point lifting rectangular arrangement into the quadrature cross arranges, and provide the steel rope winding method of quadrature cross four-point lifting lifting mechanism, therefore, 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 in length and breadth anti-sway.Simultaneously, steel rope 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 disc hoisting crane is made up 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 the end of four steel ropes 10 respectively on the reel 4, steel rope 10 is symmetrically distributed in twos, in four groovings of going into reel 4, vertical two steel rope 10 symmetries are involved in reel 4 middle parts along left and right sides rotation direction, walk around deflection sheave 6, leading sheave 7, vertical movable pulley 8-1 respectively, to equilibrium arm 11, fix, form vertically two suspension centres of symmetry; 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, fix on the wraparound equilibrium arm 11 again, form the suspension centre of two other lateral symmetry down to two horizontal movable pulley 8-2 of suspender lateral arrangement.
Steel rope canoe 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.
