As shown in Figure 1: wherein: 1 is upper cylinder, 2 be bottom roll, 3 be frame, 4 be protective cover, 5 be control box, 6 be transmission device, 7 for transmission shaft.
As shown in Figure 2, wherein, 8 be reducing motor, 9 for main driving wheel, 10 for shift fork, 11 for handle, 12 for pipe link, 13 for auxiliary driving wheel, 14 for clutch discs, 15 for main shaft, 16 be oscillating bearing; 17 is drive disk assembly.
Detailed description of the invention
As Figure 1-4, this transmission device, comprise reducing motor 8, main driving wheel 9, shift fork 10, handle 11, pipe link 12, auxiliary driving wheel 13, clutch discs 14, main shaft 15, oscillating bearing 16, drive disk assembly 17, main driving wheel 9 inside is all provided with bearing, quantity has two, is connected to main shaft about 15 two ends; Clutch discs 14 between two main driving wheels 9, and is connected with main shaft 15 by flat key; The two sides of main driving wheel 9 side and clutch discs 14 are all processed with can be mutually meshing profile of tooth; Clutch discs 14 is provided with the U-type groove that the two ends pin of shift fork 10 can be stuck in the middle part of clutch discs 14; Shift fork 10 is connected with handle 11 by pipe link 12.
This transmission device, its main driving wheel 9 and auxiliary driving wheel 13 can use belt pulley or sprocket wheel; Corresponding drive disk assembly 17 just uses belt or chain.Tooth Profile Machining is the profile of tooth of three deciles, like this so that mutually meshing with the main driving wheel 9 at two ends, reaches the function of clutch, the profile of tooth of three deciles, is respectively used to the use of three kinds of different clutch situations.
The principle of work of transmission device: when handle 11 is turned left swing angle, shift fork 10 swings an angle to the right around pipe link 12 axle center, mutually meshing with right side main driving wheel 9, after reducing motor 8 is opened, main shaft 15 and clutch discs 14 together rotarily drive right side main driving wheel 9 and rotate, thus drive upper cylinder 1 to operate; Otherwise, when shift fork 10 is turned right swing angle, after opening reducing motor 8, drive bottom roll 2 is operated; When shift fork 10 is in midway location, clutch discs 14 is all separated with the main driving wheel 9 of both sides, and upper roller 1 is approximate without under rubbing effect in frame 3 bearings at both ends with bottom roll 2, manual folding and unfolding cable very easily.
The present invention uses the double-deck cable hoist of this transmission device, comprises reducing motor 8, transmission shaft 7, frame 3, cylinder, bearing, control box 5, transmission device 6, and cylinder is divided into cylinder 1 and bottom roll 2; Transmission device 6 has two auxiliary driving wheels 13, is arranged on respectively on the transmission shaft 7 of cylinder 1 and bottom roll 2, and is connected with drive disk assembly 17; Main shaft 15 one end is arranged on reducing motor 8, and the other end is fixed in frame 3 by oscillating bearing 16.
The control box 5 of this double-deck cable hoist is arranged on below reducing motor 8; Frame 3 is provided with protective cover 4; Reducing motor 8 is hollow shaft reducing motor.Control box 5 facilitates the operation of whole cable hoist to run, and uses protective cover 4 to be for the sake of security.
Adopt the double-deck cable hoist of this transmission device 6, only need a reducing motor 8 just can realize the automatic deploying and retracting cable feature of double-deck cable hoist, its low cost of manufacture, simple and practical, safe and reliable.Especially when reducing motor 8 is not opened or worked as reducing motor 8 et out of order, swing in corresponding profile of tooth position, left and right by shift fork 10, just can realize the twisted and released of the cable of cylinder 1 and bottom roll 2 on cable hoist easily, when shift fork 10 is in midway location, both sides main driving wheel 9 and clutch discs 14 are all in released state, upper cylinder 1 is approximate without under rubbing effect in frame 3 bearings at both ends with bottom roll 2, like this, pull with hand cable, also cylinder 1 and bottom roll 2 can be driven easily to rotate, thus realize manual folding and unfolding cable.This double-deck cable winch configurations is compact, reasonable in design, easy to use, is particularly suitable for the use on power supply vehicle of meet an emergency.
Above-described embodiment, the just one of the present invention's more preferably detailed description of the invention, the usual change that those skilled in the art carries out within the scope of technical solution of the present invention and replacing all should be included in protection scope of the present invention.
