Furthermore, a reinforcing nut is welded at one end of the fork head in threaded connection with the screw rod, and the screw rod is in threaded connection with the reinforcing nut and penetrates through the reinforcing nut to be in threaded connection with the fork head.
Furthermore, the brake band is made of asbestos materials.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the steel belt is arranged, the asbestos brake belt is arranged on the inner side of the steel belt, the end parts of the steel belt and the asbestos brake belt are open, the transmission shaft penetrating out of the reduction box is positioned in the brake belt, the opening of the brake belt can be reduced by pulling the handle, so that the brake belt is attached to and clamps the transmission shaft to generate a brake effect, and the handle can be fixed by screwing the fastening bolt after being pulled, so that brake failure caused by rotation of the handle is avoided, and the operation is more convenient and safer.

Detailed Description
The utility model is further described below with reference to the accompanying drawings.
Examples
A manual brake device for a winch is shown in figure 1-2 and comprises a bottom plate 1, side plates 2, T-shaped plates 3, connecting rods 4 and steel belts 5; the two sides of the top of the bottom plate 1 are both provided with side plates 2, the lower part between the two side plates 2 is connected with a T-shaped plate 3, the top of the T-shaped plate 3 is riveted with a steel belt 5 and a brake belt 6, the brake belt 6 is positioned on the steel belt 5, and the tops of the steel belt 5 and the brake belt 6 are both open; the middle parts of two sides of the steel belt 5 are connected with the side plates 2 through connecting rods 4; a first lug seat 8 is arranged on one side of the top of the steel belt 5, a screw rod 9 is rotatably connected on the first lug seat 8, and a fork head 12 is screwed at the end part of the screw rod 9; a second lug seat 11 is arranged on the other side of the top of the steel belt 5, a handle 13 is rotatably connected to the second lug seat 11, and the handle 13 is rotatably connected with the end part of the fork head 12 through a pin shaft 14; the top of the hinged part of the handle 13 and the ear seat is provided with a fastening nut 15, and a fastening bolt 16 is in threaded connection with the fastening nut 15 and penetrates through the top of the handle 13 to be in contact with the rotating shaft.
The bottom plate 1 is arranged on one side of the reduction gearbox, so that a transmission shaft penetrating out of the reduction gearbox is positioned in the brake band 6, and the inner diameter of the brake band 6 is slightly larger than the outer diameter of the transmission shaft; after the winch slope is dragged to park, an operator quickly pulls up the handle 13, because the end part of the handle 13 is rotatably connected with the second lug seat 11 and is hinged with one end of the fork 12, the other end of the fork 12 is in threaded connection with the screw rod 9, and the other end of the screw rod 9 is rotatably connected with the first lug seat 8, when the handle 13 is pulled up, the end, connected with the handle 13, of the fork 12 is upwards tilted, the other end of the fork is downwards tilted, so that the end part of the screw rod 9 is downwards tilted, further openings at the tops of the steel belt 5 and the brake belt 6 are reduced, further the brake belt 6 contacts with the transmission shaft, friction force is generated, the transmission shaft stops rotating, and further the brake effect is achieved. When the brake needs to be performed for a long time, after the handle 13 is pulled up, the fastening bolt 16 is screwed up, so that the end part of the fastening bolt abuts against the rotating shaft connected with the handle 13 and the second lug seat 11, the handle 13 can be fixed, and the situation that an operator always applies force to the handle 13 is avoided; the reinforcing nut 10 is arranged on the screw 9, so that the firmness of the joint of the fork head 12 and the screw 9 can be improved, and the end part of the fork head 12 is prevented from cracking.
