In addition, on lift well 1, weight guide 7A, 7B have a parallel distance between vertical direction and boxes and baskets guide rail 2A, 2B, and bootable thus counterweight 8 moves at vertical direction.The axle of guide wheel 9 is bearing in the top of counterweight 8, and the other end of above-mentioned main cable 5 is on guide wheel 9 and be bearing on the beam of top side.
On the other hand, on the top of lift well 1, a supporting base 10 is installed and a hoisting crane 11 is bearing on the supporting base 10.Hoisting crane 11 has a sheave 26, and leading sheave 4A, the 4B of main cable 5 by boxes and baskets 3 bottoms guides the guide wheel 9 of counterweight 8 on the sheave 26 into.
The concrete composition of hoisting crane 11 then is described.Hoisting crane 11 basic building are on the base 12 that is fixed in supporting base 10.The fixed frame 13 that promptly has upright plane 14 is arranged on the base 12, and perpendicular to uprightly plane 14 and horizontally extending anchor shaft 15 are to be stretched out by fixed frame 13 cantilevers to form.Anchor shaft 15 has a major diameter part 15a in upright plane 14 sides, and in free end side one small diameter portion 15b is arranged.One swivel mount 16 can be rotated to support on the small diameter portion 15b of anchor shaft 15 by bearing 18A, 18B.
Swivel mount 16 constitutes a cylindrical shape bottom having or cup-shaped by plate-like bottom 17 with at the perisporium 19 that its circumference forms, and 17 central authorities form a bearing retaining part 18 in the bottom.Swivel mount 16 can be rotated to support on by bearing 18A, 18B on the small diameter portion 15b of anchor shaft 15, the perforate side periphery of perisporium 19 thus, and promptly 19 of perisporium perforate side periphery is arranged to equidistantly the upright plane 14 near fixed frame 13.For the stable rotation of swivel mount 16 will be arranged to bearing 18A, 18B to have axially spaced-apart between them.Each all becomes coaxial line with the shaft centre line of anchor shaft 15 outer peripheral face 20 of the bearing retaining part 18 of swivel mount 16 and the inner and outer circumferential surfaces of perisporium 19.
In this manner with anchor shaft 15 coaxial lines the swivel mount 16 that is supported a rotor 21 was bearing on the interior week of perisporium 19.Rotor 21 can be gone up in the interior week by a plurality of permanent magnets being bonded in periphery wall 19 or the rotor core that will have a plurality of embedding permanent magnets is embedded in going up in interior week of perisporium 19 and constitutes.
The stator 22 that has diameter clearance with respect to rotor 21 is fixed on the fixed frame 13.Stator 22 comprises that having stator core 23 and the winding of having decided on stator core that the lamination silicon steel plate in the hole of being passed through by the said fixing axle makes by central authorities is formed.Stator 22 is fixed on the fixed frame 13 by support 25.
The one outer electrical motor that makes the transition is made up of the fixed frame of rotor 21, stator 22, supporting stator 22, the swivel mount 16 of supporting rotor 21 and the anchor shaft 15 of supporting swivel mount 16.Here, the outer radius portion of electrical motor is the outer peripheral face of perisporium 19 of the swivel mount 16 of supporting rotor 21.
In addition, swivel mount have be fixed on contain promptly be fixed on swivel mount on 17 outsides, round-ended cylinder shape bottom with fixed frame 13 opposite sides on sheave 26.Be sheave 26 be utilize the bearing retaining part that on swivel mount 16 bottoms 17, forms 18 outer peripheral faces 20 fixing with anchor shaft 15 coaxial lines.In such structure, because swivel mount 16 constitutes the rotating part of electrical motor, sheave 26 is mounted and fixed on the rotating part of electrical motor.For reducing the size of electrical motor, sheave 26 forms like this: make the external diameter of the diameter of cable trough 26G less than electrical motor, i.e. the outer peripheral face of swivel mount 16 perisporiums 19.Sheave 26 usefulness screws 27 screw in the bottom of swivel mount 16 and are fixed on the swivel mount 17.In addition, on the middle body of sheave 26, form a mounting hole 28 so that mounting hole 28 centers are identical with the center of cable trough 26G, and the diameter of mounting hole 28 to have such size be that bearing retaining part 18 can insert in the hole and has very little gap with the outer peripheral face of bearing retaining part 18.Therefore, because the outer peripheral face of bearing retaining part 18 is made the shaft centre line coaxial line with anchor shaft 15, as long as it is promptly consistent with the axle center of anchor shaft 15 sheave 26G to be installed to the center of cable trough 26G on the outer peripheral face of bearing retaining part 18 of swivel mount 16.
