The specific embodiment

Wireless hoisting device as shown in Figure 1 and 2, comprise screw rod 1, nut 2, counter weight base 3, bearing 4 and the bracing frame 6 for the inwall of outer support stator core 5, nut 2 is threaded with screw rod 1, counter weight base 3 is fixed in the outer ring of bearing 4, the inner ring of bearing 4 is fixed in the lower end of screw rod 1, and screw rod 1 connects counter weight base 3 rotationally by bearing 4; Bracing frame 6 is at least three, and the present embodiment is made as three, also can be three above any amount, and each bracing frame 6 distributes and arranges around the axis rotational symmetry of screw rod 1.

Bracing frame 6 comprises upper rack posts 61, lower fulcrum bar 62 and fagging 63, upper rack posts 61 is identical with lower fulcrum bar 62 shape sizes, one end of upper rack posts 61 and nut 2 are hinged, one end of lower fulcrum bar 62 and counter weight base 3 are hinged, the lateral surface of fagging 63 is the arc surface of outer arch, the medial surface of fagging 63 is fixed with jointed shaft 64, and the other end of the other end of upper rack posts 61 and lower fulcrum bar 62 is all hinged on this jointed shaft 64.

When installation, screw coordinating of screw rod 1 and nut 2, under the effect of bearing 4, nut 2 reduces with the distance of counter weight base 3, drive bracing frame 6 overhanging, thereby make the outer support of fagging 63 on the inwall of stator core 5, the locking degree of adjusting screw(rod) 1 on nut 2, the firm degree of the adjustable lifting to stator core 5.And due to multiple bracing frame 6 symmetries, and upper rack posts 61 is identical with the shape size of lower fulcrum bar 62, the arc surface that the lateral surface of fagging 63 is outer arch, for the inwall of the stator core 5 of fitting better, therefore in the time slinging screw rod 1 by outside loop wheel machine, stator core 5 can be kept steadily to sling evenly.

When dismounting, unscrew coordinating of screw rod 1 and nut 2, under the weight effect of counter weight base 3 and bearing 4, can assist the action that unscrews of screw rod 1 and nut 2, now bracing frame 6 inside contracts, and fagging 63 departs from the inwall of stator core 5, thereby takes out this wireless hoisting device.

The present embodiment is fixed with one deck brake rubber block 65 in the lateral surface laminating of fagging 63, the lateral surface of this brake rubber block 65 is the arc surface of outer arch, by brake rubber block 65, stator core 5 inwalls are reliably fitted, can improve the friction force of this wireless hoisting device and stator core 5, prevent that stator core 5 from skidding.

Extend at the top of screw rod 1 a junction 11, and this connecting portion 11 has the connecting bore 12 laterally running through, and in this connecting bore 12, is snapped with suspension ring 13, is connected thereby 13, outside loop wheel machine snapping suspension ring can be completed with the lifting of this wireless hoisting device.

The bearing 4 of the present embodiment is that the inner ring of two thrust baring 41, two thrust barings 41 is all installed fixing with the lower end of screw rod 1; The end face of counter weight base 3 is fixed in the outer ring of one of them thrust baring 41, and the outer ring of another thrust baring 41 is fixed in counter weight base 3.The axial force producing when two thrust barings 41 can effectively bear screw rod 1 and rotate, has reduced the friction force that screw rod 1 rotates.

Above-mentioned embodiment is only preferred implementation of the present utility model; the scope that can not limit with this utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
