In order to make to extract the simple and convenient manufacture of winch structure, preferred technical scheme is, described cable extracts fender guard and comprises two free bearings that are arranged on described reel feed side, on described free bearing, be connected with respectively swinging mounting, between described free bearing and two described swinging mounting tops, be provided with slide shaft, described slide shaft axially and described reel axial consistent, on described slide shaft, be arranged with slide block, between the middle part of two described swinging mountings and support surface, be provided with the brute spring that described swinging mounting top is pulled away to reel, on described swinging mounting, be provided with collision block, the side that described free bearing is relative with reel is provided with the limit switch corresponding with described collision block, described limit switch and power brake are electrically connected.
Hoisting crane supply cable diameter is large, Heavy Weight, for cable end is linked closely with reel on, avoiding reeling makes end be difficult to the defect of rolling, preferred technical scheme is that described extraction winch also comprises the cable end clip that is arranged on described mandrel surface.
Simple in structure in order to guarantee clip, preferred technical scheme is, described cable end clip comprises the first half pawls and the second half pawls of pin joint, the other end of described the first half pawls and the second half pawls forms closed ring by bolt, and described the first half pawls and the second half pawl inner edges are respectively arranged with rubber gasket.
For the ease of cable drum recovery cable, extract layout and the maintenance of equipment of winch, preferred technical scheme is that described support bottom is provided with castor.
Advantage of the present utility model and beneficial effect are:
This cable drum recovery cable extracts winch and adopts motor to drive the mode of reel drum cable, simple in structure, oad is little, lightweight, easy to use, well solve the extraction problem that supply cable is changed; By cable extraction fender guard is set, can make complete machine automatically stop action when coiling resistance is excessive, the friction secondary while avoiding old cable to drag on ground damages.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figures 1 to 5; embodiment is that a kind of cable drum recovery cable extracts winch; extract winch and comprise support 1; on support 1, put and be provided with reel 2; the bearing seat 3 of center shaft one end of reel 2 and support 1 upper end is connected, and the center shaft other end of reel 2 is connected with the output shaft of retarder 4, and retarder 4 is connected with motor 6 by coupler 5; on coupler 5, be equipped with power brake 7, cable extracts winch and also comprises that the cable being connected with power brake 7 extracts fender guard.
In the present embodiment, cable extracts fender guard and comprises two free bearings 8 that are arranged on reel 2 feed sides, on free bearing 8, be connected with respectively swinging mounting 9, between free bearing 8 and two swinging mounting 9 tops, be provided with slide shaft 10, slide shaft 10 axially and reel 2 axial consistent, on slide shaft 10, be arranged with slide block 11, between the middle part of two swinging mountings 9 and support 1 surface, be provided with the brute spring 12 that swinging mounting 9 tops is pulled away to reel 2, on swinging mounting 9, be provided with collision block 13, the side that free bearing 8 is relative with reel 2 is provided with the limit switch 14 corresponding with collision block 13, limit switch 14 is electrically connected with power brake 7.
In the present embodiment, extract winch and also comprise the cable end clip that is arranged on reel 2 surfaces.
