The specific embodiment
As shown in Figure 1, 2, 3: 1 is rear quarter panel, and 14 is front side plate, is arranged in parallel, top and side at rear quarter panel 1 and front side plate 14 have upper plate 7, there is base plate 11 in bottom, and above-mentioned each plate surrounds a housing, adopts bolt and the combination of welding fixed form between each plate.
Shown in Fig. 1,3: show four fixed pulleys 6 in the inside front transverse row of housing, the endoporus of fixed pulley 6 is equipped with sheave shaft 9 by bearing 8, bearing 8 can be antifriction-bearing box, also can be plain bearing, the two end supports of sheave shaft 9 is on rear quarter panel 1 and front side plate 14, and two ends are by the nut axial location.
Shown in Fig. 1,2,4: the inboard of housing be positioned at fixed pulley 6 below transverse row show five movable pulleys 12 that have endoporus 13 that can move at above-below direction.One end of movable pulley 12 is processed with back race 15, and the other end is processed with preceding race 19; On front side plate 14, be processed with shifting chute 18 before the movable pulley that above-below direction is provided with, shifting chute 4 behind the movable pulley relative that rear quarter panel 1 is provided with that above-below direction is provided with shifting chute 18 before the movable pulley.The dual-side of shifting chute 4 matches behind the movable pulley on the back race 15 of movable pulley 12 1 ends and the rear quarter panel 1, the dual-side of shifting chute 18 matches before the preceding race 19 of movable pulley 12 other ends and the movable pulley on the front side plate 14, and promptly movable pulley 12 can be with respect to rear quarter panel 1 and front side plate 14 knee-actions.
As shown in Figure 1: movable pulley 12 and fixed pulley 6 mutual dislocation are arranged.Be wound with same continuously and regulate steel rope 2 on movable pulley 12 and fixed pulley 6, the two ends of regulating steel rope 2 are fixed on the housing.To be the left end of regulating steel rope 2 be fixed on the inboard of the upper plate 7 of housing by left connecting element 3 to fixed form, and the right-hand member of regulating steel rope 2 is fixed on the inboard of the upper plate 7 of housing by right connecting element 16.Wherein left connecting element 3 and right connecting element 16 are wedge type steel rope termination clamp fitting structure commonly used, and as long as also available pressing plate and bolt fixed mode clamp fitting are fixed.Upper fixed at housing is connected with suspension ring 10, and the bottom of suspension ring 10 is welded with connecting panel, and this connecting panel passes through bolt with the seat board that is welded on midways location above the upper plate 7.
Above-mentioned movable pulley 12 also can be quill shaft shape tumbler, as long as can lay winding wire ropes can move with respect to the rotatable also above-below direction of housing simultaneously; Above-mentioned housing also can adopt tower structure, utilizes the shaped steel welding production.
During use, the steel rope that connects each suspension centre of goods all is connected (referring to Fig. 5) with the endoporus of one of them movable pulley by attaching parts 17 is corresponding respectively, and attaching parts can be selected lifting industry U type steel rope attaching parts commonly used for use.In this device since each movable pulley 12 can be in housing moves along the vertical direction, be wound with same between each movable pulley 12 and each fixed pulley 6 and regulate steel rope 2, if connect the steel rope discontinuity equalization of each suspension centre during the lifting goods, can regulate by regulating moving voluntarily of steel rope and each movable pulley, make each movable pulley 12 bear identical load, finally reach the steel rope stress equalization that connects each suspension centre.If run into large tonnage goods during lifting operation temporarily, and there are not suitable large-tonnage hoisting wirerope or soft hanging belt, can utilize the steel rope lifting large-tonnage goods of this device with less tonnage, but must guarantee that each movable pulley bonded assembly lifting can bear the summation of tonnage greater than the goods total weight with rope, needn't buy temporarily or take other modes solve corresponding lifting utensil, overcome at ordinary times seldom use, the time is in idle state and wastes the phenomenon of resource mostly.
