Description

Technical Field

[0001] This utility model relates to a handling device applicable to electrical cabinets (or distribution cabinets) of various specifications, belonging to the field of transportation device technology. Background Technology

[0002] In numerous industries such as power, telecommunications, and data centers, distribution cabinets are widely used as key equipment for distributing and controlling electrical energy and protecting electrical components. In power systems, substations and power plants require regular maintenance, upgrades, and relocation of distribution cabinets; distribution cabinets for communication base stations need to be moved as networks expand and equipment is updated; and data centers, due to their extremely high requirements for power supply stability, frequently involve the relocation of distribution cabinets during construction and renovation. These distribution cabinets (or electrical cabinets) vary in size, from small distribution boxes to large high-voltage distribution cabinets, and in weight, from tens of kilograms to several tons. They contain various precision electrical components, requiring handling equipment capable of adapting to the handling needs of different specifications of distribution cabinets and providing reliable protection during transport to ensure that the surface and internal components of the distribution cabinets are not damaged.

[0003] In the past, the handling of electrical distribution cabinets often relied on manual labor or simple handling tools, such as manual forklifts. Manual handling, due to the weight and size of the distribution cabinets, not only consumes a lot of manpower and is inefficient, but also makes it difficult to ensure even force distribution during transport. If the distribution cabinet tilts or its center of gravity becomes unstable, internal electrical components are easily loosened or detached, causing equipment damage and potentially leading to personnel injuries. While ordinary manual forklifts can alleviate the burden of manpower to some extent, their load-bearing capacity is limited for some large and heavy distribution cabinets. Furthermore, when moving distribution cabinets with small base dimensions but large heights on uneven surfaces, the cabinets are prone to swaying or even tipping over, resulting in damage to the surface and internal components. In addition, manual forklift operation requires a lot of space and cannot be used in narrow, confined working environments, reducing the efficiency of distributing distribution cabinets.

[0004] Chinese Patent Application No. 202420978025.8 discloses a handling device for an electrical cabinet, including a trolley, a push handle, and a trolley base. The trolley base is U-shaped, with the bottom of the push handle fixed to the upper right side of the trolley base. The left side of the trolley base is open, and a lifting mechanism is provided on the top of the trolley base. A retraction component is provided on the front of the lifting mechanism, and two clamping components are provided on the front of the retraction component. The lifting mechanism includes a frame and a lifting block. The frame is a square frame, and the bottom of the frame is fixedly connected to the upper right side of the trolley base. The frame has a threaded rod and two sliding rods inside. The two ends of the threaded rod pass through the upper and lower sides of the frame and are rotatably connected to the frame. The threaded rod is located in the middle of the frame. The two ends of the sliding rod are fixedly connected to the upper and lower side walls of the inner cavity of the frame. The sliding rods are located on both sides of the threaded rod. Although the handling device can prevent the electrical cabinet from shaking, it relies on clamping the side wall of the electrical cabinet to move it. During the handling process, the clamping plate can easily slip between the clamping plate and the side wall of the electrical cabinet, causing the cabinet surface to be scratched. In order to prevent the clamping plate from slipping between the clamping plate and the electrical cabinet, the clamping force can only be increased, but increasing the clamping force can easily cause the electrical cabinet to deform.

[0005] With increasing emphasis on safety across industries and ever-accelerating project deadlines, higher standards are being set for the efficiency and safety of power distribution cabinet handling. National and industry-specific safety regulations are constantly being improved, clearly stipulating that effective measures must be taken during equipment handling to prevent equipment damage and personnel injuries. For example, power industry safety operating procedures require that power distribution cabinets be kept stable during handling to avoid vibration and collisions. Simultaneously, to reduce project costs and improve economic efficiency, efficient handling operations have become a necessity. This urgently necessitates a handling equipment specifically designed for the characteristics of power distribution cabinets to overcome the shortcomings of traditional handling methods.

The bottom of the main frame 1 is equipped with wheels 4 for easy manual movement. The lifting mechanism is installed on the main frame 1 and is used to lift the distribution cabinet. The lifting mechanism includes a winch shaft 2, a bearing 3, a rotating handwheel 6, a winch locking rod 7, a rope winding winch 8, a steel wire rope 9, and a fixed pulley 11. The anti-sway rope 10 is used to secure the bottom of the distribution cabinet to prevent it from swaying during transportation.

[0028] The main frame 1 includes a rectangular frame 1-1, a U-shaped frame 1-2, and four columns 1-3. The upper ends of the four columns 1-3 are fixedly connected to the four corners of the rectangular frame 1-1, and the lower ends are fixedly connected to the four corners of the U-shaped frame 1-2. Four fixed pulleys 11 are installed at the upper part of the four corners of the rectangular frame 1-1 through pulley mounting brackets; the opening side of the U-shaped frame 1-2 forms the entrance of the distribution cabinet of the main frame 1. A winch shaft 2 and a winch locking rod 7 are provided between the two columns 1-3 on each side of the U-shaped frame 1-2. Both ends of the winch shaft 2 are rotatably connected to the two columns 1-3 through bearings 3 respectively. Each winch shaft 2 has a rope winding winch 8 installed at both ends and a rotating handwheel 6 fixed in the middle. The rotating handwheel 6 has radial telescopic handles around its periphery. The rotating handwheel 6 is driven to rotate by the telescopic handles. When the rotating handwheel 6 rotates, it drives the rope winding winch 8 to rotate through the winch shaft 2. One end of each of the four steel wire ropes 9 is connected to the four rope winding winches 8 respectively, and the other end passes around the four fixed pulleys 11 and is connected to the lifting rings on the four corners of the top of the distribution cabinet respectively. When the rope winding winch 8 rotates, it lifts the distribution cabinet by winding the steel wire ropes 9. The two ends of the winch locking rod 7 are fixedly connected to the two uprights 1-3 respectively, to prevent the extension handle from rotating and to prevent the distribution cabinet from falling to the ground. Four wheels 4 are installed at the bottom of the U-shaped frame 1-2. One end of the four anti-sway ropes 10 is tied to the four support legs at the bottom of the distribution cabinet, and the other end is tied to the four uprights 1-3 respectively, to prevent the distribution cabinet from swaying and colliding with the main frame 1 during transportation.

[0029] Figure 2The pulley mounting bracket includes a frame 15, a pin 12, two mounting plates 13, and four fixing bolts 14. The two rectangular mounting plates 13 are respectively attached to the upper and lower surfaces of the rectangular frame 1-1. The four corners of the two mounting plates 13 are connected by four fixing bolts 14. The frame 15 is fixed on the mounting plates 13 on the upper part of the rectangular frame 1-1. The fixed pulley 11 is located at the top of the frame 15 and is rotatably connected to the frame 15 through a horizontal pin 12. Figure 2 In the middle, the frame 15 is a vertical rectangular tube.

[0031] When a distribution cabinet needs to be moved, personnel push the main frame 1, which moves to the location of the distribution cabinet 5 via the wheels 4, allowing the cabinet to enter the main frame 1. The end of the wire rope 9 is secured to the lifting ring above the cabinet 5. The telescopic handle is adjusted to the retracted position, and the handwheel 6 is turned by operating the handle. The handwheel 6 rotates, driving the winch 8 via the winch shaft 2. The winch 8 winds up the wire rope 9, lifting the cabinet 5 to the designated height. The telescopic handle is then extended, and the winch locking rod 7 prevents it from rotating and falling back down. Four anti-sway ropes 10 are then used to connect the four legs at the bottom of the cabinet to the four uprights 1-3. Personnel push the main frame 1 to the designated installation position, shorten the telescopic handle, and slowly and smoothly turn the handwheel 6 to place the cabinet 5 in the designated location. Finally, the main frame 1 is pushed away to move the next distribution cabinet.
