[0002] Hydraulic winches are small and light lifting equipment that use drum-wrapped wire ropes to lift heavy objects. At present, most of the hydraulic winches commonly used in my country are JKY hydraulic winches developed in the 1980s or winches improved on their basis. In the long-term production practice, when hydraulic winches are used on ships for loading and unloading cargoes, it is found that there are still some problems. When the single-sided hoist is in use, the single swing arm is operated, and a high-horsepower motor is required, which consumes more energy and has low loading and unloading efficiency. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes a double-drum double-swing arm hydraulic winch, which effectively solves the problem that when the single-sided hoist of the hydraulic winch is in use, a single swing arm is operated, a high-horsepower motor is required, more energy is consumed, and the loading and unloading efficiency is low.

[0005] Preferably, the double swing arm structure includes a hydraulic swing arm, guide wheel one, guide wheel two, guide wheel three and a steel cable, the hydraulic swing arm is fixed on a base, the guide wheel one is fixed below the hydraulic swing arm, the guide wheel two is above the hydraulic swing arm, the guide wheel three is at the front end of the hydraulic swing arm, and the steel cable is fixed on the drum after being guided by the guide wheel three, the guide wheel two and the guide wheel one.

[0006] In order to better achieve the effect of synchronous lifting and lowering, two groups of steel cables are arranged on the drum, one group is wound around from the upper left side of the drum and the other group is wound around from the lower right side of the drum.

[0007] In order to achieve the purpose of synchronous driving more quickly, the rollers are arranged as a whole with a partition in the middle to form two winding rollers.

[0008] Furthermore, the hydraulic swing arms are arranged in two groups symmetrically on the left and right sides, one group of hydraulic swing arms is fixed at a point on the left side and the other group of hydraulic swing arms is arranged at a point on the right side.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: the present invention proposes a double-drum double-swing-arm hydraulic winch, in which two sets of hydraulic swing arms are arranged to increase gravity by hanging cargo containers on two sets of steel cables. At this time, the two sets of steel cables are fixed on the drum, and at this time, one set of steel cables is wound around the upper left side of the drum, and the other set of steel cables is wound around the lower right side of the drum. At this time, when the drum rotates, one set of steel cables pulls the cargo container up, and the other set of steel cables pulls the cargo container down, thereby achieving left-right balance, reducing the work done by the motor, thereby saving energy, and loading and unloading on both sides to improve efficiency.

[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0016] like Figure 1 , Figure 2 and Figure 3As shown, the utility model proposes a double-drum double-swing arm hydraulic winch, including a base 1, a driving motor 2, a rotating disk 3, an operating room, a double-drum 11 winding structure 5 and a double swing arm structure 6, the driving motor 2 is arranged in the base 1, the rotating disk 3 is driven and arranged on the driving motor 2, the operating room is fixed on the rotating disk 3, the double-drum 11 winding structure 5 is arranged on the rotating disk 3, the double swing arm structure 6 is arranged on the rotating disk 3, the double-drum 11 winding structure 5 includes a fixed seat 7, a motor 8, a bearing seat 9, a rotating shaft 10 and a drum 11, the fixed seat 7 is fixed on the rotating disk 3, the motor 8 is fixed on the fixed seat 7, the bearing seat 9 is fixed on the rotating disk 3, the rotating shaft 10 passes through the bearing seat 9 and is driven and arranged on the motor 8, the drum 11 is wrapped and fixed on the rotating shaft 10, the drum 11 is arranged as a whole, and is partitioned in the middle to form two winding drums 11.

[0017] like Figure 2 and Figure 3 As shown, the double swing arm structure 6 includes a hydraulic swing arm 12, a guide wheel 13, a guide wheel 2 14, a guide wheel 3 15 and a steel cable 16. The hydraulic swing arm 12 is fixed on the base 1. Two groups of hydraulic swing arms 12 are arranged symmetrically on the left and right sides. One group of hydraulic swing arms 12 is fixed at a point on the left side and the other group of hydraulic swing arms 12 is arranged at a point on the right side. The guide wheel 13 is fixed below the hydraulic swing arm 12, the guide wheel 2 14 is arranged above the hydraulic swing arm 12, and the guide wheel 3 15 is arranged at the front end of the hydraulic swing arm 12.
