The embodiment is as follows:

as shown in fig. 1, the present invention provides a friction brake protector for a winch that is used in conjunction with a reel 1. The friction braking protector of the winch comprises a base 2, a screw rod 3, an extrusion block 4 and a brake block 5. The reel 1 is hollow, one end of the reel is connected with the rotating shaft, and the other end of the reel is open. The open end of the reel 1 is rotatably connected to the base 2. One end of the screw rod 3 is connected with a driving device 6, and the other end extends into the winding drum 1. The driving device 6 is a motor. The axis of the screw 3 is parallel to the axis of the spool 1. The extrusion block 4 is screwed to the screw 3. The extrusion block 4 is arranged in a circular truncated cone shape, and the screw rod 3 penetrates through the center of the extrusion block 4. The brake pads 5 are provided with guide studs 51 and the guide studs 51 are perpendicular to the brake pads 5. The guide post 51 is slidably disposed on the base 2 so that the guide post 51 can slide in the radial direction of the reel 1. One end of the guide post 51 far away from the brake pad 5 is arranged in an inclined plane shape in cooperation with the pressing block 4, so that when the pressing block 4 presses the guide post 51, the guide post 51 drives the brake pad 5 to move towards the inner wall of the winding drum 1.

When the friction brake protector of the winch is used, the driving device 6 drives the screw rod 3 to rotate, so that the extrusion block 4 which is in threaded connection with the screw rod 3 moves along the screw rod 3. The pressing block 4 moves to push the guide post 51 to slide, and further push the brake pad 5 to move towards the inner wall of the winding drum 1. The brake block 5 clings to the inner wall of the winding drum 1, so that the winding drum 1 stops rotating gradually, and the effect of braking the winding drum 1 is achieved. Similarly, the screw 3 rotates reversely to loosen the brake block 5 from the inner wall of the winding drum 1, so that the winding drum 1 can rotate and work.

The friction brake protector of the winch is arranged inside the winding drum 1, so that the volume of the winch is reduced. Meanwhile, the brake block 5 directly acts on the winding drum 1, so that the winding drum 1 stops rotating, the impact force generated instantly is prevented from being transmitted to the rotating shaft, and the service life is longer.

In this embodiment, the base 2 is provided with a connection head 21. The connection head 21 is inserted into one end of the roll 1. The outer wall of the connecting head 21 and the inner wall of the winding drum 1 are connected through a needle bearing 7. This ensures the stability of the connection of the reel 1 and also makes the rotation of the reel 1 smoother.

In this embodiment, a connecting cylinder 22 is further disposed at one end of the connecting head 21. The connecting cylinder 22 extends to the inside of the other end of the spool 1. One end of the screw rod 3 is connected to the connector 21, and the other end is connected to one end of the connecting cylinder 22 far away from the connector 21. Therefore, both ends of the screw rod 3 are stably fixed, and the connection stability of the screw rod 3 is ensured. The squeezing block 4 is provided inside the connecting cylinder 22. The inner wall of the connecting cylinder 22 is also provided with a sliding groove 23 matched with the extrusion block 4. So that the expression nubs 4 can only slide relative to the connector barrel 22 and not rotate relative to the connector barrel 22. Thereby preventing the screw 3 from rotating the extrusion block 4 and failing to interact with the guide post 51. The guide post 51 is slidably inserted through the wall of the connecting cylinder 22. The guiding studs 51 are pressed by the presser foot 4 to move towards the inner wall of the spool 1, so that the brake pads 5 brake the spool 1 well.

In the present embodiment, the brake pad 5 is provided outside the connecting cylinder 22. An extension spring is arranged between the brake pad 5 and the connecting cylinder 22. When the presser foot 4 no longer presses the guide post 51, the brake pad 5 is engaged with the outer wall of the connecting cylinder 22 under the action of the tension spring, thereby disengaging the brake pad 5 from the inner wall of the drum 1. So that the reel 1 can be smoothly rotated.

In the present embodiment, the brake pad 5 is provided with two guide posts 51 in the axial direction of the spool 1. Each guide post 51 is provided with a pressing block 4 in a fitting manner. Two guide posts 51 set up respectively in the both ends of guide plate, and then make more stable cooperation of braking piece 5 in reel 1, guarantee the stability of equipment.

In this embodiment, the screw threads at both ends of the screw 3 are reversely arranged. Two extrusion blocks 4 are each fitted to one end of the screw 3. The two squeezing blocks 4 are oppositely arranged. This causes the two extruder blocks 4 to move towards each other as the screw 3 is rotated. As shown in fig. 1, when the two pressing blocks 4 approach each other, the pressing blocks 4 press the two guide posts 51 from both ends, so that the forces applied to both sides of the brake pad 5 are more equalized. Thereby balancing the force of the brake pad 5 and stabilizing the movement.

In the present embodiment, the brake pad 5 is provided in plural numbers. Several brake pads 5 are evenly distributed around the squeeze block 4. This makes a plurality of brake pads 5 open to all around, and then makes the inside atress of reel 1 more balanced, and equipment stability is better.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
