Description

Technical Field

[0001] This utility model relates to the field of new energy engineering machinery technology, and in particular to a foldable and rotatable cable raising and lowering device. Background Technology

[0002] With the increasing application of electrification in construction machinery, new energy construction machinery such as excavators or loaders are powered by either batteries or cable reels. In some work sites, owners require construction vehicles to operate continuously without interruption. In such cases, cables are laid at the work front and shore power cabinets are installed, making cable reel power supply a suitable option.

[0003] Existing cable raising and lowering devices mostly employ fixed structures or manual methods. These devices typically consist of a cable reel, a support frame, and a control mechanism. The cable reel is used to wind the cable, while the support frame is responsible for supporting and securing the equipment. Current devices commonly use electric or manual drives to achieve cable raising and lowering, relying on simple mechanical transmission systems to complete cable stretching and retraction. Some designs also include safety devices to prevent excessive cable stretching or entanglement, such as cable tension control systems.

[0004] There are two conventional methods for arranging cable reels: one is integrated onto the engineering vehicle, and the other is arranged on a ground mounting frame. Both methods have certain drawbacks. Cable reels integrated onto engineering vehicles are limited by the vehicle's height, restricting the cable installation height and span. This prevents transport vehicles from passing through, forcing them to travel only on one side of the cable, significantly reducing site utilization. In some specific situations, this can even prevent effective operation. Furthermore, insufficient height can cause the cable to drag on the ground, increasing the risk of scraping and accidents. Cable reels arranged on ground mounting frames can raise the cable to a certain height and achieve a certain span, solving the passage problem for transport vehicles. However, disassembling and transporting the mounting brackets and re-piling the reels during relocation is costly, labor-intensive, and time-consuming, resulting in prolonged downtime for engineering vehicles and placing a heavy burden on the owner. Therefore, a foldable and rotatable cable raising and lowering device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a foldable and rotatable cable raising and lowering device, which aims to improve the safety hazards caused by cables being easily scratched by the ground or run over by vehicles due to insufficient height during operation.

[0033] Reference Figures 1-6This utility model provides an embodiment of a foldable and rotatable cable raising and lowering device, including a bottom mounting support 5. The bottom mounting support 5, in conjunction with a rotating top mounting platform 6, can rotate 360 ​​degrees, achieving the effect of adapting to multi-directional cable laying by engineering vehicles. The rotation angle is locked by a pin 9 to ensure operational stability. The rotating top mounting platform 6 is fixedly connected to the top of the bottom mounting support 5. An electrical cabinet unit 4 and a reel control cabinet 11 are fixedly connected to the top of the rotating top mounting platform 6.

The details are omitted here. A cable reel unit 1 is fixedly connected to the top of the rotating top mounting platform 6. A counterweight unit 2 is fixedly connected to the side wall of the rotating top mounting platform 6. The counterweight unit 2 is used to balance the cable tension and the weight of the support. Combined with the positioning function of the limit block 8, it prevents the device from tipping over, increasing the operational safety factor to more than 1.5 times. A cable 3 for connecting to the external control cabinet is fixedly connected to the outer wall of the cable reel unit 1. A rotating seat 21 is fixedly connected to the top of the rotating top mounting platform 6. A limit block 8 is fixedly connected to the side wall of the rotating seat 21. A support wheel 7 is rotatably connected inside the rotating seat 21. A pin 9 is slidably connected inside the rotating seat 21. A support frame 12 is rotatably connected to the side wall of the rotating seat 21. The first connecting frame 14 and the second connecting frame 20 are rotatably connected to the wall. The first connecting frame 14 and the second connecting frame 20 achieve folding movement through the hinge unit 19. With the support wheel 7, frictional resistance is reduced, achieving the effect of quickly lowering the height of the device to meet the transfer requirements. The transfer efficiency is improved by more than 40%. One end of the second connecting frame 20 is rotatably connected to the top of the rotating top mounting platform 6. One end of the second connecting frame 20 is fixedly connected to the mating surface mounting bolt 10. The outer wall of the mating surface mounting bolt 10 is fixedly connected to the first connecting frame 14. The second connecting frame 20 is set on one side of the first connecting frame 14. The side wall of the first connecting frame 14 is fixedly connected to the limit wheel unit 13. The inner wall of the first connecting frame 14 is rotatably connected to the guide pulley 16. The guide pulley 16 and the cable limiting roller 18 work together to guide the take-up and release of the cable 15, achieving the effect of preventing cable tangling and wear, and extending the cable service life by 30%. The take-up and release cable 15 is rotatably connected to the outer wall of the guide pulley 16, and the outer wall of the take-up and release cable 15 is rotatably connected to the outer wall of the cable reel unit 1. The second connecting frame 20 is rotatably connected to the side wall of the hinge unit 19, and the outer wall of the hinge unit 19 is rotatably connected to the inside of the first connecting frame 14. The cable limiting roller 18 is fixedly connected to the side wall of the first connecting frame 14, and the outer wall of the take-up and release cable 15 is slidably connected to the inner wall of the cable limiting roller 18. The first connecting frame 14 is fixedly connected to the side wall of the folding baffle 17, and the outer wall of the take-up and release cable 15 is rotatably connected to the inner wall of the folding baffle 17.

[0034] Working Principle: In operation, the bottom mounting bracket 5 is fixed to the ground, providing stable support for the entire device. The rotating top mounting platform 6 achieves 360-degree free rotation through a slewing bearing. Combined with the angle adjustment of the first connecting frame 14 and the second connecting frame 20 in the foldable cable bracket, it can flexibly adapt to the cable requirements of engineering vehicles in different operating positions. Under the coordinated control of the electrical cabinet unit 4 and the cable reel control cabinet 11, the cable reel unit 1 guides the cable reeling and unreeling 15 through components such as guide pulleys 16 and cable limiting rollers 18. This ensures smooth and tangle-free cable reeling and unreeling while raising the cable to a suitable height to prevent contact with the ground or operating vehicles. Simultaneously, the counterweight unit 2 adjusts the counterweight according to the real-time load, and combined with limiting structures such as limiting blocks 8 and pins 9, ensures that the device remains balanced and stable when bearing cable tension and its own weight.

[0035] When relocation is required, the first connecting frame 14 and the second connecting frame 20 are folded together using the hinge unit 19. The support frame 12 moves with the connecting frames after folding, assisted by the support wheels 7, reducing frictional resistance during the folding process. After folding, the connecting bolts of the bottom mounting bracket 5 are loosened. The entire device meets the transportation requirements due to the reduced height after folding and can be moved with engineering vehicles. Upon arrival at the new work site, the support is unfolded and the bottom mounting bracket 5 is fixed in reverse. The support angle is locked by the pin 9 limiting unit, and the cable reel unit 1 quickly resumes its winding and unwinding function, significantly shortening the preparation time after relocation and achieving efficient continuous operation.
