Description

Technical Field

[0001] The invention belongs to the technical field of winches, and in particular relates to an intelligent winch control device driven by a motor. Background Art

[0002] A winch is a mechanical device used to pull or lift heavy objects. It consists of a base assembly, a drive mechanism, a drum, a wire rope pulley and a wire rope. The drive mechanism drives the drum to rotate, thereby driving the wire rope pulley to wind up or release the wire rope to achieve the lifting or pulling of heavy objects. Winches are widely used in industrial production, construction, port loading and unloading and other fields. The drum of the winch in the prior art is mostly provided with rope grooves. In order to ensure the rigidity of the drum, a drum with a larger diameter is selected, resulting in a limited number of turns of wire rope unwound on the drum. At the same time, the existing driving mechanism mostly rotates at a constant speed, that is, the angular velocity of the drum is constant when it rotates. When the number of turns of wire rope on the drum increases, the linear velocity continues to increase. If the lifting height is high, the linear velocity changes greatly, and shaking, impact, etc. may occur during the lifting of heavy objects. When the winch is used to lift precision equipment such as medical equipment and optical instruments, since such equipment is usually more sensitive and cannot withstand excessive vibration and impact, when the winch is used to hoist dangerous or fragile items, such items are relatively fragile and cannot withstand greater shaking, and need to be lifted slowly and steadily to avoid leakage or damage accidents. Therefore, the winch in the prior art has safety hazards when lifting items that require precise control of the above-mentioned linear velocity and have a large change in linear velocity due to a high lifting height.

[0003] The authorization announcement number CN221644449U discloses a double-drum winch, including a base; a drum bracket is fixedly connected to the upper surface of the base and is symmetrically arranged; a reduction motor is fixedly connected to the side of the drum bracket; a winch drum is rollingly connected to the side of the drum bracket and is arranged in pairs; a brake disc is fixedly connected between the pair of winch drums; a back plate is fixedly connected to the upper surface of the drum bracket; a hinge is fixedly connected to the top of the back plate; a pressure plate is movably connected to the hinge and is arranged in pairs; a No. 1 spring is fixedly connected to the middle of the pressure plate; a No. 1 spring is fixedly connected to the base; the reduction motor rotates to drive the winch drum and the brake disc to rotate, and the winding wire rope is wound on the winch drum; the pressure plate is pressed on the winch drum under the tension of the No. 1 spring, and the rope is pressed by the pressure plate when rolling. The patented rope is pressed by the pressure plate when rolling, reducing the situation of overlapping rope rolling; the wire rope can be rolled more evenly, reducing the risk of wire rope sliding and causing the risk of cargo falling. However, this patent cannot change the limited lifting height, the safety hazards caused by the continuous increase in linear speed as the wire rope wraps more when lifting heavy objects, and the risk of heavy objects shaking. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a motor-driven intelligent winch control device, which effectively solves the problem that the drum of the prior art winch is mostly provided with rope grooves.

[0047] The steel wire rope 910 of the steel wire rope assembly 900 passes through the fixed wheel assembly 500 and the distance adjustment component in sequence and is connected to the drum assembly 200. The steel wire rope assembly 900 also includes a hook 920, and the steel wire rope 910 and the hook 920 are detachably fixedly connected.

[0048] When lifting a heavy object, the heavy object is hung directly below the hook 920. During the lifting process, the hook 920 is always in a vertical state, which prevents the heavy object from shaking back and forth to a certain extent.

[0049] The distance adjusting component includes an electric push rod assembly 600, a moving wheel assembly 700 and an adjusting assembly 800. The electric push rod assembly 600 is located on the top of the fixed base 120 and is connected to it through a support block.

One end of the second spring 860 is connected to the rectangular tube 810, and the other end is connected to the second connecting plate 850. The first displacement sensor 840 extends into the interior of the rectangular tube 810, and the second displacement sensor 870 extends into the interior of the rectangular tube 810.

[0053] The present invention also provides a method for using the above device to lift heavy objects, the method is suitable for lifting heavy objects, and the method comprises the following steps:

[0054] S1, start the reducer 410 and the electric push rod assembly 600, the reducer 410 drives the drum assembly 200 to rotate forward, the wire rope 910 connected to the drum assembly 200 is wound through the moving wheel assembly 700 and the fixed wheel assembly 500, driving the heavy object to rise, at this time the electric push rod extension shaft 610 contracts, the moving wheel assembly 700 moves to the left as a whole, and the position of the wire rope 910 in the adjustment assembly 800 is determined by the displacement sensor to adjust the running speed of the electric push rod extension shaft 610;

[0055] S2, when the electric push rod extension shaft 610 is retracted to the limit position, the reducer 410 and the electric push rod assembly 600 are stopped;

[0056] S3, making the movable base 110 run backwards by a distance d of the diameter of the wire rope 910, and reducing the speed of the reducer 410 through the PLC control system;

[0057] S4, start the reducer 410 and the electric push rod assembly 600, the drum assembly 200 rotates forward, the wire rope 910 is wound up, and the weight is lifted up. At this time, the electric push rod extension shaft 610 is extended, and the moving wheel assembly 700 moves rightward as a whole. The position of the wire rope 910 in the adjustment assembly 800 is determined by the displacement sensor to adjust the running speed of the electric push rod extension shaft 610;

[0058] S5, when the electric push rod extension shaft 610 is extended to the limit position, the speed reducer 410 and the electric push rod assembly 600 are stopped;

[0059] S6, making the movable base 110 run backwards by a distance d of the diameter of the wire rope 910, and reducing the speed of the reducer 410 through the PLC control system;

[0060] S7, start the reducer 410 and the electric push rod assembly 600 again;

[0061] S8, subsequently, whenever the electric push rod extends the shaft 610 to an extreme position, the reducer 410 and the electric push rod assembly 600 are stopped, and then the movable base 110 is moved backward and the speed of the reducer 410 is reduced to continue lifting the heavy object until the heavy object is lifted to the specified position.

[0062] It is not difficult to understand that, see Appendix Figure 7 and attached Figure 8 When the device just starts to lift, the electric push rod extension shaft 610 is in the longest extended state. When the reducer 410 and the electric push rod assembly 600 are started, the reducer 410 runs at a fixed speed, and the electric push rod extension shaft 610 runs at a certain speed to drive the moving wheel assembly 700 to move to the left. Due to the movement of the position of the moving wheel assembly 700, the distance between the second guide wheel 720 and the first guide wheel 520 will increase. Therefore, when the wire rope 910 is wound around the drum assembly 200 for the first time, the speed of lifting the heavy object is slightly greater than the linear speed of the wire rope 910 on the drum assembly 200. When the electric push rod extension shaft 610 runs to the limit position and reverses, the movable base 110 is behind When the wire rope 910 is retracted by one diameter d, the rotation speed of the reducer 410 decreases, thereby ensuring the constant linear speed of the wire rope 910 on the drum assembly 200. At this time, the electric push rod extends the shaft 610 at a certain speed to drive the moving wheel assembly 700 to move to the right. Due to the movement of the position of the moving wheel assembly 700, the distance between the second guide wheel 720 and the first guide wheel 520 will decrease. Therefore, when the wire rope 910 is wound around the drum assembly 200 for the second time, the speed of lifting the weight is slightly less than the linear speed of the wire rope 910 on the drum assembly 200. Generally speaking, when the wire rope 910 is wound around the drum assembly 200 for two turns, the average speed of lifting the weight is equal to the linear speed of the wire rope 910. Since the effective width D of the second guide wheel 720 and the diameter d of the wire rope 910 are in the following relationship: 2d≤D≤3d, when the movable base 110 retreats by a wire rope 910 diameter d, it will not affect the vertical state of the wire rope 910 at the rope outlet end of the moving wheel assembly 700.

[0063] Furthermore, when the steel wire rope 910 is wound around the second circle, the speed of the reducer 410 decreases, while the electric push rod extension shaft 610 is still extended at a preset speed, the steel wire rope 910 may contact the first connecting plate 820. At this time, the first spring 830 is compressed, and the distance between the first connecting plate 820 and the inner wall of the rectangular tube 810 on the side of the first spring 830 is reduced. The first displacement sensor 840 feeds back a signal to the PLC control system, and the PLC control system adjusts the speed of the electric push rod extension shaft 610. When the steel wire rope 910 is wound around the third circle, the steel wire rope 910 may contact the second connecting plate 850. At this time, the second spring 860 is compressed, and the distance between the second connecting plate 850 and the inner wall of the rectangular tube 810 on the side of the second spring 860 is reduced. The second displacement sensor 870 feeds back a signal to the PLC control system, and the PLC control system adjusts the speed of the electric push rod extension shaft 610.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
