Abstract

The invention discloses an elevator with a novel structure. Three or four threaded steel rails (please see the threaded steel rails in the figure 3 of the specification) serve as elevator rails installed in an elevator shaft to form a large-sized incomplete thread, a tray 4 is arranged inside the thread, external threads are formed in the outer surface of the tray, and are used in cooperation with the threaded rails, the tray can carry out rotating movement in the thread, an internal gear is arranged in the tray, and is driven by a gear 5 in a lift car to rotate, the lift car 1 is placed on the tray 4 in a connected mode through a thrust bearing 2, and the lift car is controlled through a vertical guide rod, cannot rotate, and can only vertically move. Due to the fact that a power device is placed in the lift car, and drives the gear to rotate so as to drive a tray stud to ascend or descend in a rotation mode, the lift car can be driven to ascend or descend.

Description

A kind of screw type safe cordless elevator

Technical field

The present invention is applicable to the people and goods's of high building conveying, the conveying of down-hole goods and materials etc.

Background technology

Existing elevator all adopts car to be drawn by steel cable or steel band, and driven by motor steel cable, during due to elevator motion, have steel rope breaking, power failure, motor is out of control etc., and car is possibility free-falling body just, and current technology can not be controlled the weight of whereabouts at a high speed immediately, exist very large potential safety hazard.Simultaneously there is huge structure in existing elevator, and car can only be used wire rope traction, and the shortcoming such as an elevator can only be by car of a wire rope traction, and carrying capacity is poor.

Summary of the invention

The present invention overcomes the defect of existing elevator, and a kind of structure of screw type safe cordless elevator is provided.

First the elevator rail of installing in elevator is 3 or 4 screw thread rail, the structure of screw thread rail is equivalent to a complete negative thread in circumferencial direction intercepting 3-4 part, as shown in Figure 2,3-4 rail is installed by template, form a large-scale negative thread, although screw thread is also imperfect, integral body plays a part a screw thread.In thread tracks, have a pallet, pallet outer ring is outside thread, coordinates with screw thread rail, can cause up-and-down movement in the transduction of screw thread rail inward turning, has inner gear in pallet, by the gear driven in car, is rotated.Car is placed on pallet by only taking off bearing, and car is controlled by vertical guide rod, can not rotate, and can only move up and down with pallet.In car, place engine installation, driven wheel rotarily drives the rotation of pallet double-screw bolt and rises or decline, thereby drives car to rise or decline.

Accompanying drawing explanation: the safe cordless elevator basic structure of Fig. 1: 1-car, 2-thrust bearing, 3-screw thread guide rail, 4-pallet, 5-driven wheel

Fig. 2 screw thread guide rail

Fig. 3 car inner gear driving tray structure.

Claims

1. a novel spiral cordless elevator, is characterized in that: with motor in car or power driven spiral pallet, pallet moves in track.Track is that 3-4 rail forms incomplete screw thread.Under the driving of the motor of pallet in car, make rotation and the screw motion rising.And car can only move up and down under the effect of guide rail, can not rotate.

2. the screw type safe cordless elevator based on described in claims 1, is characterized in that: elevator rail is one to be completed screw thread and become 3-4 rail by virtual dividing, and screw thread is trapezoidal, triangular form or square thread, saw thread.

3. the screw type safe cordless elevator based on described in claims 1, is characterized in that: pallet is inner to be meshed with motor-driven gear in car for inner gear, and pallet outside is helicitic texture, for reducing friction, can adopt the helical structure of ball screw type.

4. the screw type safe cordless elevator based on described in claims 1, its car often adopts circular configuration, in car, can settle drive motor, on transmission gear, manual unit can be installed, as power failure, arm revolving gear manually, driving tray is to close floor exit.

5. the screw type safe cordless elevator based on described in claims 1, can be moved in orbit by a plurality of cars, by electronics package, controls its each car segment movement, improves carrying capacity.
