firstly, the operator fixes the present invention at a designated position on the deck of the working vessel, and then powers on the controller 7 and the driving motor 41, and when the operator checks and determines that the component parts are in a normal working state, the cable recovery operation can be started.
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 assembly 4 fixed on the top seat 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 worker can more flexibly and easily operate the turntable 2. When the motor is needed to drive, the driving wheel 43 in the driving assembly 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 assembly 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 and abuts 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, the locking mechanism rotatably arranged on the pushing shaft is rotated after the position of the pushing shaft 63 is adjusted, so that 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 by the locking nut 64 to prevent the threaded part of the pushing shaft 63 from loosening due to vibration, so that the reduction of the braking force to the turntable 2 does not achieve the deceleration function.
The above description is intended to describe in detail the preferred embodiments of the present invention, but the embodiments are not intended to limit the scope of the claims of the present invention, and all equivalent changes and modifications made within the technical spirit of the present invention should fall within the scope of the claims of the present invention.
