Problems solved by technology

Its shortcomings: First, due to the long-term operation of the traction wire rope, the length of the traction wire rope will inevitably be extended due to the action of its traction gravity, and the tension pulley for adjusting the tightness of the traction wire rope is in actual use. , because it is limited by its spring length and elasticity, it cannot effectively adjust the extension of the traction wire rope to become longer, resulting in loosening of the tension of the traction wire rope in the circular drive device, the driving force is difficult to reach, and even the drive fails; the second is due to the drive In the device, the force of pulling the elevator by pulling the wire rope must not only be able to pull the wire rope, but also overcome the friction force between the wire rope and the driving wheel for the operation of the elevator, so the power consumption is particularly large

Embodiment 1

[0016] Embodiment 1: with reference to accompanying drawing 1, Fig. 2 and Fig. 4. Stairwell rotary elevator traction rope tensioning device, the moving large pulley assembly 4 is located in the tensioning frame 2 and moves along the track in the tensioning frame under the action of external force, and the tensioning frame is mainly used for positioning the large guiding pulley 1 and the small guiding pulley The pulley 7 and the guide moving track are provided for the reliable movement of the mobile large pulley assembly 4. The mobile large pulley assembly 4 is composed of a mobile frame and a large pulley 3. The large pulley 3 is installed on the mobile frame, and the guide of the mobile frame in the tension frame 2 It can move left and right (front and back) on the rail, and the small guide pulley 7 is connected to the end of the mobile frame and drives the moving large pulley assembly 4 to move through the tension rope 6 and the tension counterweight to achieve instantaneous ...

Embodiment 2

[0017] Embodiment 2: with reference to accompanying drawing 3. On the basis of Embodiment 1, the traction rope tensioning operation method of the rotary elevator in the stairwell, the traction steel wire rope located in the driving device passes through the traction rope tensioning device to move the large pulley in the large pulley assembly and the large guide pulley to form a closed loop, and the tension rope One end is hooked to the tensioning frame, the other end is connected to the tensioning counterweight through the traction pulley and the guide pulley at the other end. When the traction wire rope in the driving device runs for a long time, the traction wire rope becomes longer and At the moment when the tension becomes loose, the tension counterweight drives the large pulley assembly to move through the small guide pulley and the small traction pulley, and the large pulley in the large pulley assembly tensions the traction wire rope to keep the tension of the traction w...

Embodiment 3

[0018] Embodiment 3: with reference to accompanying drawing 4. Stairwell rotary elevator traction rope tensioning drive device, three driving wheels 18,19,20 in the cabinet 17 are arranged in the shape of a character, and its manufacturing technology is a prior art, so it will not be described here. The power output shaft of the motor 14 is directly fixed to the driving wheel 18 through the reducer 15, and the two driven driving wheels 19 and 20 are located in the cabinet through the wheel shaft, and the traction wire rope 9 is rotated through the stairwell. Wrapped on the driving drive wheel 18 and two driven drive wheels 19, 20 to form a closed loop, the load-bearing elevator chair is fixed on the traction wire rope 9.

Abstract

The present invention relates to one kind of automatic steel cable tightener for rotary elevator in stairway. The automatic steel cable tightener has large moving pulley assembly located inside the tightener frame to move along the track inside the tightener frame under the action of external force, large guide pulley in one corner inside the tightener frame, small guide pulley in the opposite corner inside the tightener frame and connected to the large moving pulley assembly, tightening cable with one end hung to inside the tightener frame and the other end connected with the drawing cable tightener assembly via the small drawing pulley and the small guide pulley, and drawing cable around the large moving pulley and large guide pulley. The present invention has the advantages of absorbing the length extension of the drawing cable at all time, low power consumption and low elevator running cost.

Description

Technical field: [0001] The invention relates to an automatic tensioning device for a power traction wire rope of a rotary elevator in a stairwell, and belongs to the field of automatic tensioning devices for power-driven traction wire ropes. Background technique: [0002] All the patent numbers of this application are 03119642.X, and the name is "cycle traction driving device". The three worm wheels rotate synchronously, the three traction wheels are coaxial with the three worm wheels and rotate synchronously, and the traction wire rope is wound on the three traction wheels to form a closed loop. The traction wire rope is stuck in the trapezoidal rope groove of the traction wheel. The greater the power of traction, the greater the friction between the traction wire rope and the traction wheel groove. The tightness of the traction wire rope is automatically adjusted by the tension wheel. Its shortcomings: First, due to the long-term operation of the traction wire rope, the ...
