The specific embodiment
As shown in Figure 1, lift appliance of the present invention has: a hollow column shape hoist trunk 1; Be arranged on a pair of car guide rail 2 and a pair of weight guide 3 in this hoist trunk 1; Led by car guide rail 2 and the car 4 of lifting in hoist trunk 1; Led by weight guide 3 and the counterweight 5 of lifting in hoist trunk 1; The towing machine 6 that top disposed in hoist trunk 1 as the actuating device main body; The center shaft horizontal fixed is connected in the drive pulley 7 of above-mentioned towing machine 6 output shafts; Volume hangs on the drive pulley 7, and in hoist trunk 1 car 4 and counterweight is hung the main rope 8 of lifting for 5 times; The a pair of volume that is arranged on car 4 bottoms is hung the car hanging wheel 10,11 of main rope 8; Be arranged on the top of counterweight 5, volume is hung the counterweight hanging wheel 9 of main rope 8; Be arranged on the top of counterweight 5, fixedly mount the main frame anchor fitting 12 of towing machine 6 in the above.
As shown in Figure 2, a longitudinal plane and its orthogonality of center shaft at the center of gravity place of above-mentioned drive pulley 7, this longitudinal plane are the longitudinal median plane Y of drive pulley; The line of above-mentioned a pair of weight guide 2 on same level height is the line of centers X of so-called weight guide.
As shown in Figure 3, above-mentioned main frame anchor fitting 12 is made up of the elastic shock attenuation element 14 between main frame anchor fitting top 18, main frame anchor fitting bottom 19 and top and the bottom; Towing machine 6 directly is fixedly connected with main frame anchor fitting top 18, elastic shock attenuation element 14 with main frame anchor fitting top 18 and main frame anchor fitting bottom 19 resilient connection together, main frame anchor fitting bottom 19 is fixed on a pair of weight guide 3 simultaneously and closes on this car guide rail 2 to weight guide 3 with relative, and this main frame anchor fitting 12 is horizontally disposed with.
Next, in conjunction with the accompanying drawings 3 and accompanying drawing 4, along the composition and the basic structure of the whole lift appliance of main rope 8 explanations.From being arranged on the second main rope fastener 17 in car 4 left sides, main rope 8 at first comes downwards to the first car hanging wheel 10 along vertical, to the right around this hanging wheel after about 1/4 week, level strides across bottom surface to the second car hanging wheel 11 of car 4, make progress around this hanging wheel after about 1/4 week, edge roughly vertical goes upward to drive pulley 7, after making progress earlier, hang drive pulley after 7 about 1/2 weeks to last volume, edge roughly vertical comes downwards to counterweight hanging wheel 9, scroll up extension counterweight hanging wheel downwards after 9 about 1/2 weeks through elder generation, edge roughly vertical goes upward to the first main rope fastener 13. that is installed on the main frame anchor fitting bottom 19
As shown in Figure 2, when vertical is seen, be in the oblique configuration of above-mentioned drive pulley 7 levels of above-mentioned counterweight 5 tops in above-mentioned hoist trunk 1, the line of centers X of its longitudinal median plane Y and described weight guide intersects.Being not only the longitudinal median plane Y of drive pulley and the line of centers X of weight guide intersects, in order to reduce drive pulley 7, towing machine 6 and main frame anchor fitting 12 together to above-mentioned guide rail, especially to the moment of torsion of weight guide, present embodiment disposes the center of gravity of drive pulley 7 (in Fig. 2, its projection in vertical direction is in point among the line segment of longitudinal median plane Y of expression drive pulley) approaching with the line of centers X of weight guide ten minutes.In fact, such configuration mode has also been taken into account the needs that the extension of the longitudinal median plane Y that makes drive pulley overlaps with the longitudinal median plane of counterweight hanging wheel 9 simultaneously, the longitudinal median plane of so-called counterweight hanging wheel 9 is meant one of the center of gravity place of counterweight hanging wheel 9 longitudinal plane with counterweight hanging wheel 9 orthogonality of center shaft.Obviously, such configuration has reduced the windup-degree of main rope 8 between drive pulley 7 and counterweight hanging wheel 9 simultaneously, like this, both can reduce drive pulley 7 and counterweight hanging wheel 9 center shafts are subjected to horizontal torsion, also can reduce the wearing and tearing of main rope 8 and drive pulley 7 and counterweight hanging wheel 9, improve the travelling comfort of elevator simultaneously.Understandablely be, as further preferred, in the present embodiment, overlap mutually between the vertical projection three of the vertical projection of the vertical projection of above-mentioned drive pulley 7 centers of gravity, above-mentioned counterweight hanging wheel 9 centers of gravity and above-mentioned counterweight 5 centers of gravity, and, the above-mentioned main rope 8 that volume is hung on the above-mentioned counterweight hanging wheel 9 between above-mentioned first main rope fastener 13 and counterweight hanging wheel 9 that section and the position of another section between above-mentioned drive pulley 7 and counterweight hanging wheel 9 with respect to the vertical vertical plane surface symmetry at the center of gravity place of counterweight 5.Pei Zhi benefit is that weight guide 3 is stressed even like this, no partial load, and counterweight 5 is moved more smooth and easy in weight guide 3.
Because the difference of factors such as mounting condition, under the basic demand that the line of centers X of longitudinal median plane Y that satisfies drive pulley and weight guide intersects, as long as the center of gravity of drive pulley 7 being configured in the line of centers X of the weight guide of its place height goes up or disposes it approaching with the line of centers X of weight guide as far as possible, the then making of whole lift appliance and installing no matter whether can take into account following technical requirements, all be can accept and can produce the technique effect that is better than prior art: the extension of the longitudinal median plane Y of (1) drive pulley overlaps with the longitudinal median plane of counterweight hanging wheel 9; (2) overlap mutually between the vertical projection three of the vertical projection of the vertical projection of drive pulley 7 centers of gravity, counterweight hanging wheel 9 centers of gravity and counterweight 5 centers of gravity; (3) main rope 8 that volume is hung on the counterweight hanging wheel 9 in the position of that section between the first main rope fastener 13 and the counterweight hanging wheel 9 and another section between drive pulley 7 and counterweight hanging wheel 9 with respect to a vertical vertical plane surface symmetry at the center of gravity place of counterweight 5.
