Preferably, the force piece is hollow shaft motor, the outer wall of the screw thread and the inner wall of hollow shaft of hollow shaft motor It is fixed.

By adopting the above technical scheme, nut can be driven to rotate by air spindle motor, and then drives screw rod along vertical side To lifting, while hollow shaft can utilize cross sectional moment of inertia to greatest extent, save material.

Preferably, the electric machine support is equipped with two guide rails extended along the vertical direction, and the both ends of the traction frame are set There is the limiting slot with guide rail clamping.

By adopting the above technical scheme, it is clamped by the limiting slot and guide rail at traction frame both ends, to improve the lifting of traction frame Stability, by being clamped by limiting slot and guide rail to limit to traction frame, limitation traction frame occurs in lifting process Rotation, and then improve the stability of traction frame and screw rod lifting.

Preferably, the outer wall of the carriage set there are four with guide rail cooperation guide shoe.

By adopting the above technical scheme, cooperated by the guide rail of the guide shoe of carriage and elevator bracket, reduce the shaking of carriage, mention Stability of high carriage during lifting.

Preferably, the fixed sleeving for screw rod insertion extended along the vertical direction is equipped with below the force piece.

By adopting the above technical scheme, screw rod is gone up and down under the drive of nut and ball along axis direction, when screw rod is inserted When entering into fixed sleeving, fixed sleeving can play the role of protection to screw rod.

Preferably, the side of opening of the elevator bracket close to carriage is equipped with the entrance of disengaging carriage, the discrepancy The door-plate for covering entrance is hinged at mouthful.

By adopting the above technical scheme, people can be facilitated to pass in and out carriage, while hinged door at entrance by entrance Plate can cover entrance, to guarantee carriage in lifting process, the security and stability of personnel in carriage.

Preferably, the door-plate is equipped with handle.

By adopting the above technical scheme, the mobile door-plate of people is facilitated by handle.

Preferably, the hoist ropes is wirerope.

By adopting the above technical scheme, the intensity of wirerope it is high, from heavy and light, stable working, be not easy whole root fracture suddenly, work Reliably.

In conclusion the utility model has the following beneficial effects:

1. drive the lifting of traction frame to drive the lifting of traction sheave by driving assembly, thus under the pulling of hoist ropes, Carriage is gone up and down in elevator bracket, reduces the slipping phenomenon between traction sheave and hoist ropes, improves the stabilization of elevator lifting Property；
