Description
Technical Field
[0001] This utility model relates to the field of winch technology, and in particular to a winch with four ropes and integrated power supply. Background Technology
[0002] A winch is a lifting device that uses wire ropes or chains to traction and lift heavy objects. In specific situations, it is used as a suspending device for decorative displays, lighting fixtures, etc. Traditional suspending methods typically employ at least two winches in coordination: one winds the cable to transmit power to the lighting fixtures, while the other winds the wire rope to lift the heavy object. This results in a large structural footprint, wasting resources in limited indoor spaces. Furthermore, when suspending heavy equipment, the different tensile loads of the wire ropes and cables make it difficult to evenly distribute the weight across multiple winches. This can lead to lifting deviations due to the greater load on the cables, affecting the stability of the suspending operation. Therefore, there is an urgent need for a winch that integrates suspending and power supply to solve these problems. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] Reference Figures 1-5 This utility model provides a four-rope suspended power supply integrated winch, comprising:
[0032] Mounting plate 1, with a drive shaft 2 rotatably connected to its top surface;
[0033] A pair of drum sets 3 are sleeved and fixedly connected to the drive shaft 2 and are symmetrical about the center of the drive shaft 2. Any drum set 3 includes two single drums 31 that are fixedly connected coaxially, and a steel wire cable 4 is wound on the single drum 31.
[0034] Rope follower 5, the same number as the single drum 31 and corresponding one-to-one, is sleeved on the outside of the single drum 31. One end of the steel wire cable 4 extends out of the single drum 31 and passes through the rope follower 5. The rope follower 5 is slidably fixed relative to the mounting plate 1. Several rope followers 5 move synchronously. The mounting plate 1 is equipped with a fire cut-off limit switch. The limit switch 6 of the fire cut-off limit component is connected to any one of the rope followers 5.
[0035] Among them, electric slip rings 7 are respectively provided at the far ends of a pair of drum groups 3. The electric slip rings 7 are fixed to the mounting plate 1 and are used to energize the steel wire cable 4.
[0036] This invention utilizes a drive shaft 2 connected to a mounting plate 1 to drive a pair of drum assemblies 3 to rotate symmetrically around the center of the drive shaft 2. Each drum assembly 3 includes two coaxially fixed single drums 31. Through the steel wire cables 4 wound on the single drums 31, the mounting plate 1 can simultaneously wind and unwind four steel wire cables 4. The steel wire cables 4 provide power while suspending heavy objects. The suspension tension is evenly distributed by the sequential distribution of the four steel wire cables 4. In addition, four rope guides 5 are connected to the four single drums 31. As the single drums 31 rotate, the steel wire cables 4 move the rope guides 5. The synchronous movement of the four rope guides 5 ensures the suspension stability during the winding and unwinding of the steel wire cables 4. Furthermore, by simply connecting the limit switch 6 of the fire cut-off limiter to any one of the rope guides 5, the travel of all four rope guides 5 can be detected synchronously, ensuring the lifting and lowering limit function.
[0037] Furthermore, electric slip rings 7 are provided on both sides of the mounting plate 1. The electric slip rings 7 are energized with the steel wire cable 4 and maintain the rotation of the single drum 31 to achieve the winding and unwinding control of the steel wire cable 4.
[0038] Furthermore, by fixing two pairs of support rods 8 to one side of the top surface of the mounting plate 1, any pair of support rods 8 is arranged on both sides of the drum assembly 3. A sliding rod 9 is fixed between the pair of support rods 8, and the sliding rod 9 is fixed to the mounting plate 1. By fitting a sliding sleeve 10 on the sliding rod 9, and the number of sliding sleeves 10 is the same as that of the rope follower 5 and they are fixed one-to-one, the rope follower 5 is slidably fixed to the mounting plate 1. Using the locking sleeve 11 installed on the inner side wall of the single drum 31, one end of the steel wire cable 4 is fixed in the locking sleeve 11, and the other end of the steel wire cable 4 extends out of the single drum 31 and is wound around the single drum. On the outer periphery of the drum 31, a groove 12 is opened on the outer periphery of the single drum 31. The groove 12 is distributed in a spiral shape. The steel wire cable 4 is embedded in the groove 12. The groove 12 is used to limit and guide the winding and unwinding of the steel wire cable 4, so that the steel wire cable 4 is evenly wound on the single drum 31 in a spiral shape. During the winding and unwinding process, the position of the steel wire cable 4 extending out of the single drum 31 moves along the groove 12. During this process, the rope follower 5 moves synchronously. The rope follower 5 contacts the limit switch 6 of the fire cut-off limiter to realize the monitoring and control of the lifting position of the steel wire cable 4.
[0039] In this technical solution, the locking sleeve 11 can adopt a common expansion sleeve structure to fix the steel wire cable 4 at the position where the steel wire cable 4 extends out of the single drum 31, forming a fixed winding end of the steel wire cable 4 on the single drum 31.
[0040] Furthermore, it also includes:
[0041] A pair of fixed seats 13 are fixedly connected to the top surface of the mounting plate 1 on both sides. The top of the fixed seat 13 is fixedly connected to the outer ring side of the bearing 23. The two ends of the drive shaft 2 extend out of the single drum 31 in a mutually distancing direction and are fixedly connected to the inner ring side of the bearing 23.
[0042] The support plate 14 is fixedly connected to the side of the fixed seat 13 away from the single drum 31. A connecting plate 15 is fixedly connected to the top surface of the support plate 14. The fixed end of the electric slip ring 7 is fixedly connected to the connecting plate 15. Several through holes are opened on the connecting plate 15. A power line 16 is passed through the through holes and connected to the steel wire cable 4 for power supply.
[0043] The support plate 14 is fixedly connected to the mounting plate 1 by the fixed seat 13. At the same time, the drive shaft 2 is rotated to the fixed seat 13 by the bearing 23 on the fixed seat 13. The electric slip ring 7 is fixedly connected to the support plate 14 by the connecting plate 15. The rotating end of the electric slip ring 7 is fixedly connected to the drive shaft 2. The power cable 4 is energized by the power line 16 to ensure the integrated function of the hanging power supply.
[0044] Specifically, the electric slip ring 7 is used for the energization connection between the fixed end and the rotating end. It is a conventional design and will not be described in detail.
[0045] Furthermore, a transition shaft 17 is fixedly connected to the side end face of the drive shaft 2. A connecting hole is provided on the transition shaft 17. The connecting hole extends to the center of the drive shaft 2 and connects the inside and outside of the single drum 31. One end of the power cord 16 extending out of the electric slip ring 7 passes through the connecting hole.
[0046] The transmission shaft 2 is fixedly connected to the transition shaft 17, and a connecting hole is provided on the transition shaft 17 to fix the rotating end of the electric slip ring 7 to the transition shaft 17, keeping the power line 16 relatively fixed, and the power line 16 directly connects to the steel wire cable 4 in the single drum 31 to realize the integrated suspension power supply of the steel wire cable 4.
[0047] Furthermore, it also includes:
[0048] The height limiter 18 is fixedly connected to any one of the plates 14. The detection shaft of the height limiter 18 passes through the connecting plate 15 in the horizontal direction and is coaxially fixedly connected to the transmission shaft 2.
[0049] In this technical solution, a height limiter 18 is also provided. The height limiter 18 is fixedly supported by the support plate 14, and the detection shaft of the height limiter 18 is directly coaxially fixed with the transmission shaft 2. Combined with the fire cut-off limiter and the rope follower 5, the position of the single drum 31 winding and unwinding the steel wire cable 4 is monitored and controlled in a dual manner, thereby improving the safety of the overall winch.
[0050] Furthermore, a reduction gearbox 19 is fixedly connected to the center of the mounting plate 1. A servo motor 22 is connected to the power input end of the reduction gearbox 19, and the power output end of the reduction gearbox 19 is fixedly connected to the transmission shaft 2.
[0051] Specifically, the reduction gearbox 19 adopts a common worm gear 20 and worm 21 reduction structure. The worm gear 20 is sleeved and fixed on the transmission shaft 2, and the output shaft of the servo motor 22 is coaxially fixed with the worm 21. The worm 21 meshes with the worm gear 20, so that the servo motor 22 drives the transmission shaft 2 to rotate. The reduction gearbox 19 is used as a connection and fixing medium to fix the servo motor 22 on the mounting plate 1, and the transmission shaft 2 passes through the reduction gearbox 19 so that a pair of drum groups 3 are symmetrically distributed along the center of the transmission shaft 2.
[0052] This utility model provides a working principle for a winch with integrated power supply and four-rope suspension:
[0053] When hanging decorative items and lighting fixtures, the mounting plate 1 is fixed to the indoor ceiling, allowing the steel wire cable 4 to extend vertically downwards from the single drum 31. The servo motor 22 is started to drive the transmission shaft 2 to rotate, synchronously driving the four single drums 31 to rotate. The spiral groove 12 is used to wind and unwind the steel wire cable 4. During the process, the rope follower 5 is sleeved on the single drum 31. As the steel wire cable 4 extends, the rope follower 5 moves axially along the single drum 31. After the rope follower 5 contacts the limit switch 6 of the fire cut-off limiter, the servo motor 22 is turned off, causing the four single drums 31 to stop synchronously. This achieves even distribution of the weight of the suspended heavy object and effectively ensures the stability during the lifting process.
