[0002] A hoisting winch is a mechanical device widely used in various fields such as ocean engineering, oil drilling, ship loading and unloading, construction, and mining operations. Its main function is to drive a drum to rotate through an electric motor or a hydraulic motor, thereby winding and unwinding a steel wire rope or a cable for hoisting, dragging, lifting, or placing heavy objects.
[0003] When the existing hoisting winch winding device is in use, it can only fixedly wind a drum of a single size, which limits its scope of use in different working scenarios and applications. For an operating environment that needs to handle goods or cables of various sizes, this limitation will greatly reduce the versatility and efficiency of the device. Secondly, the existing hoisting winch winding device lacks the ability to adjust tension, which means that when the winch hoists or lowers a heavy object, the tension of the steel wire rope may not be adjusted in a timely manner according to the actual situation. Excessive tension of the steel wire rope will increase its internal stress, accelerate fatigue, shorten the service life, and even cause sudden fracture; while too loose a steel wire rope may cause slipping, running off the groove, or uneven winding, increasing the operation risk.
[0004] Therefore, a winding device for a hoisting winch is proposed. Content of the Utility Model

[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] Through the arranged reel clamping mechanism, the utility model can solve the problem that only reels of a single size can be fixedly wound, which limits its use range in different working scenarios and applications. By rotating the handwheel, the external thread sleeve can rotate on the first connecting block, and at the same time drive the screw sleeve to move and adjust. By moving and adjusting the screw sleeve, the three groups of the first connecting frames and the second connecting frames are driven to move and adjust. At the same time, the second insertion pin shafts between the three groups of second connecting blocks rotate, and the first insertion pin shafts between the three groups of bushings rotate. Through the activities of the fourth insertion shafts overlapping each other between the three groups of the first connecting frames and the second connecting frames, and the cooperation of the two third insertion pin shafts movably inserted at both ends of the three arc-shaped abutting plates, the three arc-shaped abutting plates can be expanded. Through the exquisitely designed reel clamping mechanism, especially the combination of the external thread sleeve, the screw sleeve, the first connecting block, the second connecting block, and the corresponding connecting frames and insertion pin shafts, the device can accurately adjust and adapt to reels of different diameters. Only by rotating the handwheel can the relative positions of the various components be easily adjusted to achieve perfect clamping of reels of different specifications, greatly improving the versatility and flexibility of the equipment. The use of the arc-shaped abutting plates, combined with the movable insertion of the third insertion pin shafts, enables the abutting plates to effectively cover the surface of the reel in the expanded state, providing a strong radial supporting force to ensure that the reel is stable and does not deviate during the winding and unwinding operations, avoiding potential safety hazards caused by the loosening of the reel, improving the stability and safety of the operation, and effectively solving the problem that only reels of a single size can be fixedly wound, which limits its use range in different working scenarios and applications.
[0016] The utility model can solve the problem of lack of tension adjustment ability through the two adjustment mechanisms provided. That is, when the winch hoists or lowers a heavy object, the tension of the steel wire rope may not be adjusted in a timely manner according to the actual situation. One of the adjustment mechanisms provided is arranged oppositely to the second adjustment mechanism. The steel wire rope passes through the first adjustment mechanism and the second adjustment mechanism, and is respectively located between the first pulley group in the two adjustment blocks and the two second pulley groups. By controlling the operation of the third motor, the second screw rod rotates to drive the adjustment block to move. At the same time, the adjustment block slides on the two sliding rods, so as to synchronously drive the components on the adjustment block to move and adjust. By controlling the operation of the two first hydraulic cylinders, the first telescopic rod can be telescoped to make the second telescopic rod telescoped, which can abut and drive the two second sliders of the first adjustment mechanism to slide in the two second chutes and the first through groove respectively to realize the movement adjustment of the first adjustment mechanism. Then, by controlling the operation of the two second hydraulic cylinders, the second telescopic rod can be telescoped, which can abut and drive the two second sliders of the second adjustment mechanism to slide in the two third chutes and the fourth through groove respectively to realize the movement adjustment of the second adjustment mechanism. The two adjustment mechanisms arranged oppositely in the design can work synchronously or independently, which means that no matter whether the steel wire rope is released or recovered from the winch, continuous adjustment of the tension can be achieved, ensuring the stability and safety of the operation process, and effectively solving the problem of lack of tension adjustment ability, that is, when the winch hoists or lowers a heavy object, the tension of the steel wire rope may not be adjusted in a timely manner according to the actual situation.

A bushing 205 is fixedly sleeved on the end of the stepped shaft 201 far from the screw sleeve 204. Six first connecting blocks 210 are fixedly connected to the bushing 205 at equal intervals. The six first connecting blocks 210 are divided into two groups;
[0031] There are two first connecting frames 207 evenly spaced between three groups of first connecting blocks 210 and three groups of second connecting blocks 212. There are two second connecting frames 208 evenly spaced between the six first connecting frames 207. A first insertion pin shaft 211 is movably inserted between the three groups of bushings 205.

By controlling the operation of the third motor 28, the second screw rod 27 rotates to drive the adjusting block 21 to move. At the same time, the adjusting block 21 slides on the two sliding rods 26, so that the components on the adjusting block 21 can be driven to move and adjusted synchronously. By controlling the operation of the two first hydraulic cylinders 16, the first telescopic rod 17 can be telescoped, and the second telescopic rod 31 can be telescoped, which can abut and drive the two second sliders 20 of one adjusting mechanism 38 to slide in the second sliding groove 18 and the first through groove 19 on the first support frame 14 and the second support frame 15 respectively, so as to realize the movement adjustment of one adjusting mechanism 38. Then, by controlling the operation of the two second hydraulic cylinders 30, the second telescopic rod 31 can be telescoped, which can abut and drive the two second sliders 20 of the other adjusting mechanism 38 to slide in the third sliding groove 32 and the fourth through groove 33 on the third support frame 29 and the fifth support frame 37 respectively, so as to realize the movement adjustment of the other adjusting mechanism 38. The two oppositely arranged adjusting mechanisms 38 in the design can work synchronously or independently, which means that continuous adjustment of the tension can be achieved whether the steel wire rope 13 is released or recovered from the winch, ensuring the stability and safety of the operation process;
[0042] When it is necessary to replace the reel with different size specifications, first control the first motor 5 to work, so that the first screw rod 3 rotates to drive the first slider 4 to slide and adjust in the first chute 9. At the same time, the bearing 8 and the cross-groove block 7 on the support plate 6 move synchronously, so that the cross-groove block 7 no longer engages with the cross-slider 202. Then, by rotating the handwheel 209 counterclockwise, the external thread sleeve 203 can rotate on the first connecting block 210, and at the same time drive the screw sleeve 204 to move and adjust. By moving and adjusting the screw sleeve 204, the three first connecting frames 207 and the second connecting frame 208 are driven to move and adjust. At the same time, the second insertion pin shaft 213 between the three second connecting blocks 212 rotates, and the first insertion pin shaft 211 between the three bushing sleeves 205 rotates. Through the movement of the fourth insertion pin shaft overlapping crosswise between the three first connecting frames 207 and the second connecting frame 208, and the cooperation of the two third insertion pin shafts movably inserted at both ends of the three arc-shaped abutting plates 206, the three arc-shaped abutting plates 206 can be contracted so that they no longer fixedly engage with the reel 12. At this time, the reel 12 is pulled out, and the new reel 12 to be replaced is movably sleeved on the reel clamping mechanism 2. Similarly, by rotating the handwheel 209 clockwise, the external thread sleeve 203 can rotate on the first connecting block 210, and at the same time drive the screw sleeve 204 to move and adjust. By moving and adjusting the screw sleeve 204, the three first connecting frames 207 and the second connecting frame 208 are driven to move and adjust. At the same time, the second insertion pin shaft 213 between the three second connecting blocks 212 rotates, and the first insertion pin shaft 211 between the three bushing sleeves 205 rotates. Through the movement of the fourth insertion pin shaft overlapping crosswise between the three first connecting frames 207 and the second connecting frame 208, and the cooperation of the two third insertion pin shafts movably inserted at both ends of the three arc-shaped abutting plates 206, the three arc-shaped abutting plates 206 can be expanded to clamp the new reel 12 tightly. At this time, by working the first motor 5 again, the first screw rod 3 rotates to drive the first slider 4 to slide and adjust in the first chute 9. At the same time, the bearing 8 and the cross-groove block 7 on the support plate 6 move synchronously, so that the cross-groove block 7 engages with the cross-slider 202. This design facilitates the replacement of the reel 12, and can accurately adjust and adapt to reels with different diameters. Only by rotating the handwheel 209 can the relative positions of each component be easily adjusted to achieve perfect clamping of reels with different specifications, greatly improving the versatility and flexibility of the equipment. The use of the arc-shaped abutting plate 206, combined with the movable insertion of the third insertion pin shaft, enables the abutting plate to effectively cover the surface of the reel in the expanded state, providing a strong radial supporting force to ensure that the reel is stable and does not shift during the winding and unwinding operations, avoiding safety hazards caused by the loosening of the reel and improving the stability and safety of the operation.
