Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a rotating frame and a power distribution vehicle. Background Technology

[0002] With increasing environmental awareness and technological advancements, more and more heavy industrial equipment is adopting electricity as its primary power source. This shift not only helps reduce noise and air pollution at construction sites but also improves energy efficiency and lowers operating costs. However, in practical applications, the power supply methods for some heavy industrial equipment that requires frequent movement, such as excavators and pile drivers, face a series of challenges.

[0003] In traditional operating models, powering these mobile heavy-duty equipment typically involves using long-distance cables directly connected to a fixed power point, which presents significant safety hazards in practice. First, the complex and varied environment of construction sites, with ground surfaces often riddled with obstacles, makes floor-mounted cables prone to snagging or damage, potentially causing power outages or even accidents. Second, prolonged dragging during significant equipment movement can lead to excessive stretching or twisting of the cables, affecting their lifespan and safety. Furthermore, the cable laying and retrieval process is time-consuming and labor-intensive, increasing operational difficulty and time costs.

[0004] To address these issues, the industry has gradually developed a new solution: using specially designed power distribution vehicles to move alongside heavy-duty equipment and effectively manage cables. These vehicles can automatically retract and extend cables, ensuring they maintain appropriate tension and do not touch the ground, thus significantly reducing the risk of cable damage. During the movement of the equipment, the power distribution vehicle adjusts its angle using its wheels to adapt to the equipment's position relative to the vehicle, as the cable drags along. Since the working environment of the equipment is typically a construction site with uneven ground, the wheels may get stuck on uneven surfaces or obstacles, hindering movement and potentially causing the vehicle to tip over due to the cable dragging. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a rotating frame and a power distribution vehicle, which can solve the problem that the angle of the power distribution vehicle relative to the power distribution vehicle can only be adjusted by the wheels.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] A rotating frame, comprising:

[0008] A first frame, the first frame is provided with a cable reel and a cable bracket, and the cable wound on the cable reel passes through the cable bracket;

[0009] The second frame is provided with a plurality of wheels, all of which are located on both sides of the second frame;

[0010] A rotating element is provided, through which the first frame and the second frame are connected, so that the first frame can rotate relative to the second frame.

[0011] Furthermore, the first frame is provided with a first stop on the side facing the second frame, so that the first stop moves with the first frame. The second frame is provided with two second stops on the side facing the first frame, and both second stops are located on the movement trajectory of the first stop.

[0012] Furthermore, the rotating member has a rotation axis, and the two second stops are symmetrically arranged on both sides of the first stop with the line connecting the first stop to the rotation axis of the rotating member as the axis of symmetry.

[0013] Furthermore, with the rotation axis of the rotating component as the center, the central angle formed by the line connecting the first stop to the rotation axis of the rotating component and the line connecting any of the second stopes to the rotation axis of the rotating component is 90 degrees.

[0014] Furthermore, the first stop has abutment surfaces on both sides that abut against the second stop on both sides, and gaskets are provided on the abutment surfaces.

[0015] Furthermore, both of the second stops have abutment surfaces provided with gaskets for abutting against the first stop.

[0016] Furthermore, the cable bracket has a cable passage structure through which the cable passes, and the projection of the cable passage structure in the vertical direction is not on the rotation axis of the rotating component.

[0017] Furthermore, the cable bracket is located at one end of the first vehicle frame.

[0018] Furthermore, the rotating component is a slewing bearing, and the first frame and the second frame are connected through the slewing bearing.

[0019] This utility model also provides a power distribution vehicle, including the aforementioned rotating frame.

[0020] In summary, the rotating frame and power distribution vehicle provided by this utility model have the following technical effects:

[0021] 1. By placing the cable reel on the first frame and allowing the cable to pass through the cable support, the cable can be effectively managed, preventing it from dragging directly on the ground and potentially getting caught or damaged by obstacles at the construction site. This not only reduces the risk of power outages but also improves the safety of the entire system.

[0022] 2. Since the first and second frames are connected by a rotating component, the first frame can rotate relative to the second frame. Therefore, the power distribution vehicle can flexibly adjust its angle when moving with the electrical equipment to adapt to changes in the working position of the electrical equipment. When using this rotating frame on uneven ground or in complex environments, the rotation between the first and second frames replaces the existing technology of adjusting the position by the wheels, which greatly reduces the possibility that the wheels may encounter obstacles or get stuck in potholes. This makes it less likely that the wheels will get stuck or have their rotation restricted, thereby greatly reducing the risk of rollover. Attached Figure Description

[0029] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described and discussed below with reference to the accompanying drawings. Obviously, what is described here is only a part of the examples of this invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the protection scope of this invention.

[0030] To facilitate understanding of the embodiments of this utility model, further explanations and descriptions will be provided below with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the embodiments of this utility model.

[0031] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0033] See Figures 1-5 This utility model discloses a rotating frame, including a first frame 1, a second frame 2 and a rotating component 3. The first frame 1 is provided with a cable reel 11 and a cable bracket 12. The cable 13 wound on the cable reel 11 passes through the cable bracket 12. The second frame 2 is provided with a plurality of wheels 21. All the wheels 21 are located on both sides of the second frame 2. The first frame 1 and the second frame 2 are connected by the rotating component 3 so that the first frame 1 can rotate relative to the second frame 2.

[0034] Specifically, the cable reel 11 is used to wind and unwind the cable 13. When the power distribution vehicle moves with the electrical equipment, the cable 13 can be automatically unwound or retracted from the cable reel 11, ensuring that the cable 13 always maintains appropriate tension. The cable bracket 12 is used to provide a higher exit point for the cable 13, that is, to increase the distance of the cable 13 from the ground, so that when the electrical equipment is working in an uneven environment, the cable 13 is less likely to be caught on obstacles. The cable reel 11 and the cable bracket 12 are both mounted on the first frame 1, which ensures that the cable reel 11 and the cable bracket 12 can rotate with the rotation of the first frame 1. Then, according to the external force, generally the tension applied to the cable 13 by the electrical equipment, the cable bracket 12 is adjusted to face the electrical equipment, preventing the cable bracket 12 from being unable to adjust its orientation when the wheel 21 is stuck. The second frame 2 is equipped with multiple wheels 21, all mounted on both sides of the second frame 2, ensuring the stability and mobility of the vehicle. The wheels 21 support the weight of the entire frame and allow it to travel smoothly on uneven ground. The first frame 1 is rotatably connected to the second frame 2 via a rotating component 3, thereby enabling the rotation of the first frame 1 to replace the rotation of the second frame 2. In other words, the rotating frame can adjust its angle without relying on the steering of the wheels 21 to adapt to changes in the position of the electrical equipment.

[0035] The rotating component 3 between the first frame 1 and the second frame 2 can be a slewing bearing or a simple shaft structure, which is not limited here, as long as it can enable the first frame 1 to rotate relative to the second frame 2.

[0036] In some embodiments, the first frame 1 is provided with a first stop 14 on the side facing the second frame 2, so that the first stop 14 moves with the first frame 1. The second frame 2 is provided with two second stop 22 on the side facing the first frame 1, and both second stop 22 are located on the movement trajectory of the first stop 14.

[0037] Specifically, the first stop 14 is installed on the first frame 1 and rotates together with the first frame 1. The first stop 14 is located on the side of the first frame 1 facing the second frame 2, that is, the opposite side of the two frames. The two second stop 22 are respectively installed on the side of the second frame 2 facing the first frame 1. Both second stop 22 are located on the movement trajectory of the first stop 14. Thus, whether the first stop 14 rotates clockwise or counterclockwise with the first frame 1, it will abut against one of the second stop 22 and restrict the rotation of the first frame 1. This effectively limits the maximum rotation angle of the first frame 1 relative to the second frame 2, thereby preventing the first frame 1 from rotating excessively and avoiding the problem of cable 13 getting tangled.

[0038] In some embodiments, the rotating member 3 has a rotation axis, and two second stops 22 are symmetrically arranged on both sides of the first stop 14 with the line connecting the first stop 14 to the rotation axis of the rotating member 3 as the axis of symmetry.

[0039] Specifically, since the two second stops 22 are symmetrically arranged, when the first frame 1 rotates in any direction, the first stop 14 will first contact one of the second stops 22 and stop further rotation. This symmetrical arrangement ensures that when placing the rotating frame, the construction personnel can relatively accurately judge the rotation range of the first frame 1, so as to place the rotating frame in a position with sufficient rotation space in advance.

[0040] In some embodiments, with the rotation axis of the rotating member 3 as the center, the central angle formed by the line connecting the first stop 14 to the rotation axis of the rotating member 3 and the line connecting any second stop 22 to the rotation axis of the rotating member 3 is 90 degrees.

[0041] Specifically, when the rotation angle of the first frame 1 relative to the second frame 2 remains within 90 degrees, the center of gravity of the entire system is relatively stable, that is, the center of gravity is biased towards the position of the heavier cable reel 11. Under this condition, even if the ground is slightly uneven, the vehicle can still maintain good balance. Once the rotation angle exceeds 90 degrees, the position of the cable reel 11 on the first frame 1 is significantly displaced relative to the second frame 2. If the construction personnel do not take this effect into account in advance, a rollover may occur.

[0042] In some embodiments, the first stop 14 has abutting surfaces on both sides that abut against the second stop 22 on both sides, and a gasket 4 is provided on the abutting surfaces.

[0043] Specifically, the first stop 14 is mounted on the first frame 1 and rotates together with it. Two second stopes 22 are respectively mounted on the second frame 2, located along the movement trajectory of the first stop 14, ensuring that when the first frame 1 rotates to a certain angle, the first stop 14 will contact one of the second stopes 22. Each side of the first stop 14 has an abutment surface for contacting the corresponding second stop 22. A shim 4 is provided on the abutment surface of the first stop 14 to absorb some impact force, further improving the stability of the rotating frame during rotation.

[0044] Furthermore, both second stops 22 have abutment surfaces for abutting against the first stop 14, each provided with a gasket 4.

[0045] Similarly, a gasket 4 is also provided on the contact surface of the second baffle that abuts against the first baffle 14, which can also absorb the impact force.

[0046] The gasket 4 can be made of rubber, plastic or other wear-resistant materials, and can be selected according to the specific application environment and requirements.

[0047] In some embodiments, the cable bracket 12 has a cable 13 passage structure through which the cable 13 passes, and the projection of the cable 13 passage structure in the vertical direction is not on the rotation axis of the rotating member 3.

[0048] Specifically, the cable bracket 12 has a cable 13 passage structure, which guides and secures the cable 13, ensuring that the cable 13 can pass through smoothly and maintain a proper path. The cable 13 passage structure can be any type of channel, such as a hole or conduit, as long as it does not interfere with the extension and retraction of the cable 13 within the structure. The vertical projection of the cable 13 passage structure is not on the rotation axis of the rotating component 3; that is, the cable 13 passage structure is eccentrically positioned relative to the rotation axis. When the cable 13 passage structure is eccentrically positioned, the tension on the cable 13 will not act directly on the rotation axis, but will be applied at an off-center position. This helps maintain the relative stability of the entire system's center of gravity and reduces the risk of tipping over due to the tension of the cable 13.

[0049] In some embodiments, the cable bracket 12 is disposed at one end of the first frame 1.

[0050] Specifically, since the cable bracket 12 is located at one end, when the cable 13 is under tension, the first frame 1 can respond more quickly, causing the entire first frame 1 to rotate smoothly. This arrangement makes the first frame 1 respond more quickly to changes in the tension of the cable 13 and can adjust the angle in a timely manner.

[0051] Furthermore, when the cable bracket 12 is located at one end of the first frame 1, the lever arm of the cable 13 relative to the axis of rotation becomes longer, resulting in a greater torque under the same tension. Therefore, even if the rotating component 3 experiences slight jamming, the larger torque can help overcome this resistance, enabling the first frame 1 to achieve stable rotational adjustment.

[0052] In some embodiments, the rotating component 3 is a slewing bearing, and the first frame 1 and the second frame 2 are connected by the slewing bearing.

[0053] Specifically, slewing bearings can withstand large radial and axial loads, making them suitable for applications in complex environments. They provide a stable support structure for components such as cable reels. Furthermore, the low coefficient of friction of slewing bearings ensures smooth and efficient rotation. Even under prolonged use or frequent rotation, they maintain good performance, reducing wear and maintenance requirements.

[0054] This utility model also provides a power distribution vehicle, including the aforementioned rotating frame.

[0055] Optionally, the power distribution vehicle employs the aforementioned rotating frame. The first frame 1 is equipped with a cable reel 11 and a cable bracket 12, with the cable 13 extending from the reel 11 and passing through the bracket 12. The second frame 2 is equipped with multiple wheels 21, all mounted on both sides of the second frame 2, ensuring stability and mobility on uneven terrain. A slewing bearing, serving as a rotating connection between the first frame 1 and the second frame 2, allows the first frame 1 to rotate 360 ​​degrees relative to the second frame 2. A first stop 14 and a second stop 22 limit the maximum rotation angle of the first frame 1 relative to the second frame 2, preventing cable 13 entanglement and other potential problems caused by excessive rotation, while providing a two-way protection mechanism, enhancing the stability and safety of the power distribution vehicle.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
