In order to make the simple and convenient manufacture of extraction winch structure, preferably technical scheme is, described cable extraction protection device includes two free bearings being arranged on described reel feed side, it is connected to swinging mounting on described free bearing, it is provided with sliding axle between described free bearing and two described swinging mounting tops, described sliding axle axially and described reel axial consistent, it is arranged with slide block on described sliding axle, it is provided with, between middle part and the support surface of two described swinging mountings, the brute spring that described swinging mounting top is pulled away from reel, it is provided with collision block on described swinging mounting, the side that described free bearing is relative with reel is provided with the limit switch corresponding with described collision block, described limit switch is electrically connected with power brake.
Crane service cable diameter is big, Heavy Weight, in order to cable end is linked closely with on reel, it is to avoid winding makes end be difficult to the defect of rolling, and preferred technical scheme is, described extraction winch also includes the cable end clip being arranged on described mandrel surface.
In order to ensure clip simple in construction, preferably technical scheme is, described cable end clip includes 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 Guan Bi ring by bolt, and described the first half pawls and the second half pawl inner edges are respectively arranged with rubber packing.
For the ease of layout and the maintenance of equipment of cable drum maintenance cable extraction winch, preferred technical scheme is, described support bottom is provided with castor.
Advantages of the present invention and having the beneficial effects that:
This cable drum maintenance cable extraction winch uses motor to drive the mode of reel winding cable, and simple in construction, overall dimensions are little, lightweight, easy to use, well solve the extraction problem that service cable is changed；Complete machine can be made to be automatically stopped action when wind resistance is excessive by arranging cable extraction protection device, it is to avoid friction secondary damage when old cable drags on ground.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figures 1 to 5; embodiment is a kind of cable drum maintenance cable extraction winch; extraction winch includes support 1; put on support 1 and be provided with reel 2; central shaft one end of reel 2 is connected with the bearing block 3 of support 1 upper end, and the central shaft other end of reel 2 is connected with the output shaft of decelerator 4, and decelerator 4 is connected with motor 6 by shaft coupling 5; being equipped with power brake 7 on shaft coupling 5, cable extraction winch also includes the cable extraction protection device being connected with power brake 7.
In the present embodiment, cable extraction protection device includes two free bearings 8 being arranged on reel 2 feed side, swinging mounting 9 it is connected on free bearing 8, it is provided with sliding axle 10 between free bearing 8 and two swinging mounting 9 tops, sliding axle 10 axially and reel 2 axial consistent, slide block 11 it is arranged with on sliding axle 10, it is provided with, between middle part and support 1 surface of two swinging mountings 9, the brute spring 12 that swinging mounting 9 top is pulled away from reel 2, collision block 13 it is provided with on swinging mounting 9, 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, extraction winch also includes the cable end clip being arranged on reel 2 surface.
In the present embodiment, cable end clip includes the first half pawls 15 and the second half pawls 16 of pin joint, and the other end of the first half pawls 15 and the second half pawls 16 forms Guan Bi ring by bolt, and the first half pawls 15 and the second half pawl 16 inner edges are respectively arranged with rubber packing 17.
In the present embodiment, support 1 bottom is provided with castor 18.
When cable drum maintenance cable extraction winch uses, need to walk around the crane cable end of maintenance from slide block bottom, in the cable end clip become by the first half pawls and the second half claw types, fastening bolt tighten up fixing.Connect motor power, power brake obtain electric after brake block release, electric machine rotation, through shaft coupling, decelerator drive spool turns, crane cable is extracted by reel coiling action.
When crane cable take-up force is excessive; swinging mounting is promoted to overcome brute spring pulling force to swing around free bearing; after swinging mounting swings certain angle, collision block can touch limit switch; limit switch controls power brake dead electricity; power brake brake block is braked; reel coiling action stops, thus the crane cable that protection is keeped in repair.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
