Have the advantages that braking time is short, electromagnetic braking motor 7 is connect with speed reducer 14, and motor rotational shaft speed is adjusted to elevator needs
Revolving speed and exported by the speed reducer output shaft of speed reducer 11, speed reducer 14 connect with mechanism of twisting rope, in the present embodiment, subtracts
Fast machine 14 and two mechanism of twisting rope or so are connect, and duplex type is driven so that suspension platform uniform force, runs smoothly, and carry suspention
It will not be rotated automatically when platform is without guiding, in the other embodiments of the utility model, speed reducer 14 and mechanism of twisting rope
The quantity of connection determines that mechanism of twisting rope quantity is more according to specific operating condition, and suspension platform is more stable but self weight increases.Mechanism of twisting rope
Including cabinet 12, the casing part of cabinet 12 and the composition mechanism of twisting rope of case lid 11 protects the inner body of mechanism of twisting rope not by outer
The influence of portion's environmental factor.Directive wheel 6 is pivotally connected by shaft in cabinet 12, rope distributor 5, rope distributor 5 are installed below directive wheel 6
Right side assembles lever plate 3, and the upper end of lever plate 3 is articulated on cabinet 12 by positioning pin 8 and is located at 6 right side of directive wheel, positioning
8 periphery of pin is equipped with guide roller 15, between cabinet 12 and lever plate 3.Rope distributor 5 and guide roller 15 are to wirerope
Operating path be oriented to.The inside middle portion of lever plate 3 is by the hinged pressure rope idler wheel 4 of connecting pin 16, in the lower part of lever plate 3
Side is provided with spring block 19, is equipped in the middle part of spring lever 2 and passes through spiral shell by 17 connecting spring bar 2 of trundle, 2 right end of spring lever
Bolt is fixed on the spring stop 18 of cabinet 12, and the circular hole slided for spring lever 2, pressure rope spring 10 are provided on spring stop 18
It is sheathed on part of the spring lever 2 between spring stop 18 and spring block 19.Regulating device is connected on the left of spring lever 2,
Regulating device is to adjust screw 1 in the present embodiment, adjusts screw 1 by screw-threaded counterbore and is mounted on 12 side of cabinet, practical at this
Regulating device can be miniature straight line slide unit in novel other embodiments.Drive disk 9 is installed, drive disk 9 is equal on the right side of lever plate 3
Cloth lightening hole, alleviates self weight under the premise of not influencing its intensity, and drive disk 9 is connected with circlip through cabinet 12 simultaneously by key
Mechanism of twisting rope drive shaft 13 positioned at 9 center of drive disk, speed reducer output shaft is mechanism of twisting rope drive shaft in the present embodiment
13。
Wirerope enters inside cabinet 12 by directive wheel 6, penetrates wirerope level when into rope and is more advantageous into rope,
Wirerope enters drive disk 9 under rope distributor 5 and the common guiding role of guide roller 15, rotates along drive disk 9, passes through pressure rope rolling
After wheel 4, it is discharged except cabinet 12 by 5 guiding role of rope distributor.After wirerope is smoothly put on, the rope stretching side under mechanism of twisting rope effect
Change 90 ° into rope direction to opposite.Mechanism of twisting rope provides pressure by pressure rope spring 10, is selected according to different job requirements corresponding
The pressure rope spring 10 met the requirements, and be tightly compacted wirerope in the rope groove of drive disk 9 by pressure rope idler wheel 4, generate foot
Enough frictional force, thus the movement with dynamic loading.Spring lever 2 is driven to move downward by turning adjusting screw 1 first, spring lever
2 drive lever plates 3 are rotated clockwise around positioning pin 8, and the gap between pressure rope idler wheel 4 and drive disk 9 increases, when gap size is big
When the size of wirerope, wirerope can be slided freely in mechanism of twisting rope, can realize the length tune to two wirerope
Section guarantees both sides synchronous effect.Then turning adjusting screw 1 adjusts screw 1 and spring lever 2 is driven to move right, 2 band of spring lever
Dynamic lever plate 3 is rotated counterclockwise around positioning pin 8, and the gap between pressure rope idler wheel 4 and drive disk 9 reduces, when pressure rope idler wheel 4 is by steel
When cord is pressed on drive disk 9, i.e. pressure rope spring 10 is right by pressure rope idler wheel 4 to the thrust and wirerope of lever plate 3
When the resistance of lever plate 3 is identical, that is, realize the adjusting to wirerope and mechanism of twisting rope frictional force.
