When the brake is released, the brake lug 812 rotates counterclockwise by a certain angle under the pulling of the return spring 816, so that the edge of one side, close to the turntable 2, of the brake lug 812 is higher than the edge of one side, far away from the turntable 2, of the brake lug 812, therefore, in the process of the next brake, one end, close to the turntable 2, of the brake lug 812 rotates counterclockwise along with the brake foot rest 813, is firstly in abutting contact with the outer circumferential surface of the turntable 2, and then rotates clockwise, so that the brake surface of the whole brake lug 812 is completely abutted and abutted with the outer circumferential surface of the turntable 2.

The locking assembly 82 comprises a locking base 821, a locking spring 823 and a locking foot rest 822, a long strip-shaped U-shaped hole 8211 is formed in the parking bottom plate 814 along the length direction of the parking bottom plate, the locking base 821 is fixedly installed in the U-shaped hole 8211 of the parking bottom plate 814 through screws, therefore, the fixing position of the locking base 821 on the parking bottom plate can be moved according to needs in the later period, the transverse distance from the locking base 821 to the support 3 is adjusted, the long strip-shaped U-shaped hole 8211 is formed in the locking base 821 along the vertical direction, a hinge shaft of the locking foot rest 822 is hinged and arranged in the U-shaped hole 8211 of the locking base 821, the vertical position of the locking foot rest 822 can be adjusted by adjusting the position of the hinge shaft in the U-shaped hole 8211 in the later period, the locking spring 823 is connected and arranged between one side, close to the turntable 2, of the locking foot rest 821, a limiting shaft 827, the locking foot rest 822 can be in a vertical state under the matching of the limiting shaft 827, the limiting hole and the locking spring 823, a bayonet 825 is formed in the locking foot rest 822, the bayonet 825 is used for clamping the locking stop foot rest 813, an inclined surface 824 is arranged at the top end of the head of the locking foot rest 822, after the inclined surface 824 extrudes the locking foot rest 822 to the inclined surface 824 in the process that the stop foot rest 813 rotates anticlockwise and downwards, the locking foot rest 822 rotates anticlockwise for a certain angle, and then the stop foot rest 813 continues to rotate anticlockwise until the locking shaft 8131 is clamped into the bayonet 825 to achieve locking.

Because the angles rotated by the braking foot rests 813 are different when the rotary disc 2 is completely braked and stopped in the process of braking different rotary discs 2, in the actual braking and stopping state of different winches, the included angle between the tail end of each braking foot rest 813 and the horizontal plane is different, so that the positions of the clamping shafts 8131 of different winches are different when the winches are braked and stopped, in addition, the rubber anti-slip pads 811 are gradually worn along with later friction loss, the braking positions of the same winch are not fixed and unchanged, as shown in fig. 11, and therefore, the transverse and vertical long strip-shaped U-shaped holes 8211 are respectively formed in the braking bottom plate 814 and the locking base 821 to adjust the positions of the locking foot rests 822, so as to ensure that the braking foot rests 813 in different braking positions can be locked by the bayonets 825 on the locking foot rests 822, and thus facilitating actual installation and adjustment. Since the locking foot 822 is adjustable in vertical position on the locking base 821, the limiting hole provided in the locking foot 822 is not a standard arc-shaped hole, but a special-shaped hole 826 as shown in fig. 11.

An adjustable and extensible adjusting foot frame 818 is fixed at the tail of the braking foot frame 813, and can be adjusted according to requirements in actual use.

EXAMPLE III

As shown in fig. 12, in this embodiment, the first embodiment is combined with the second embodiment, and the hand braking device 6 and the foot braking device 8 are combined and installed on the same set of winch at the same time, so that the operator can optionally perform speed reduction and braking on the winch through any one of the braking devices, thereby facilitating the operation of the operator on the winch in the actual working process.

The working principle of the present invention is described by taking the first embodiment as an example:

firstly, the staff will the utility model discloses fixed settling is in the assigned position of operation ship deck, then for controller 7 and driving motor 41 switch on, when each subassembly part is in normal operating condition, alright in order to begin the recovery work of carrying out the cable in the inspection confirmed.

When the cable is collected, firstly, the worker winds and fixes the end of the cable on the winding drum 1, and then can select whether the rotating disc 2 is driven to rotate by the driving motor 41 or driven by manpower according to the requirement. When the required manual operation turntable 2 rotates, firstly, the adjusting screw 55 in the position adjusting assembly 5 is rotated to enable the positions of the connecting block 54 and the supporting block 56 to approach each other, so that the top seat 51 slides to the side away from the turntable 2 under the driving of the connecting block 54, and drives the driving device 4 fixed thereon to be away from the turntable 2, so that the driving wheel 43 and the outer surface of the turntable 2 are away from each other, and at the moment, when a worker manually operates the turntable 2, the worker can not be influenced by the resistance of the driving motor 41, and the manual operation is more flexible and easier. When the motor is needed to drive, the driving wheel 43 in the driving device 4 moves towards the direction close to the turntable 2 by rotating the adjusting screw 55 until the outer rubber part of the driving wheel 43 tightly abuts against the outer circumferential surface of the turntable 2, and the driving wheel 43 can drive the turntable 2 to move by friction force when rotating, and then the movement of the turntable 2 can be adjusted by pressing the button on the controller 7.

When the speed needs to be reduced, firstly, the adjusting hand wheel 66 in the hand brake device 6 is rotated, the pushing shaft 63 is driven by the adjusting hand wheel 66 to move to the side close to the turntable 2 on the mounting frame 62, because the end part of the pushing shaft 63 rotates to abut against the back surface of the pressing block 61, the pressing block 61 is driven by the pushing shaft 63 to approach the turntable 2, the friction pad 612 fixed on the arc-shaped clamping plate 611 of the pressing block 61 gradually abuts against and presses the outer circumferential wall of the turntable 2, the rotating speed of the turntable 2 is reduced by adjusting the pressing force, if a certain friction force needs to be provided for a long time to reduce the speed of the turntable 2, after the position of the pushing shaft 63 is adjusted, the locking mechanism rotatably arranged on the pushing shaft is rotated, the end surface of the locking nut 64 abuts against the mounting frame 62, the pushing shaft 63 is fixed on the mounting frame 62 through the locking nut 64, and the situation that the matching of the threaded part of the pushing shaft 63 is loosened due to vibration is prevented from occurring due to the fact that Accordingly, the braking force to the turntable 2 is reduced, and the deceleration function cannot be realized.

The above description is for the detailed description of the preferred possible embodiments of the present invention, but the embodiments are not intended to limit the scope of the present invention, and all equivalent changes or modifications accomplished under the technical spirit suggested by the present invention should fall within the scope of the present invention.
