Description

Technical Field

[0001] This utility model relates to the field of heavy industrial equipment technology, and in particular to a power distribution vehicle frame and 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 industrial 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. Since the power distribution vehicle is responsible for power distribution, a distribution box needs to be installed on it. Because the working environment of the power distribution vehicle often contains many rocks, during operation, heavy industrial machinery and passing vehicles such as cars and trucks may eject small rocks due to tire pressure. Therefore, the distribution box is highly susceptible to the impact of flying rocks, posing a significant safety hazard. Utility Model Content

[0028] 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.

[0029] 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.

[0030] 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.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] See Figures 1-4 This utility model discloses a power distribution vehicle frame, including a frame body 1, a protective cabinet 2 and a cable reel 3. The protective cabinet 2 is located on one side of the frame body 1. The protective cabinet 2 has a cavity inside for assembling a power distribution box. The protective cabinet 2 has a cabinet door 21 on one side. The cable reel 3 is located on the side of the frame body 1 away from the protective cabinet 2.

[0033] Specifically, the frame body 1 serves as the supporting structure for the entire power distribution vehicle frame. The frame body 1 bears the protective cabinet 2, cable reel 3, and other components to be installed later, ensuring its stability and integrity. The protective cabinet 2 is located on one side of the frame body 1, and the cable reel 3 is located on the other side. This allows the traction arm of the frame body 1 to be positioned on the side of the frame body 1 where the protective cabinet 2 is located when the frame body 1 is towed. Since the cable reel 3 has a relatively large weight, placing it on the side away from the traction arm improves its slope-crossing performance. The protective cabinet 2 has an internal cavity for assembling the power distribution box, providing a safe and stable installation environment. A cabinet door 21 is located on one side of the protective cabinet 2, facilitating maintenance and repair of the power distribution box while ensuring its safety during operation. The cable reel 3 is used to store and manage the cables 4, ensuring that the cables 4 remain orderly and not dragged during the movement or operation of the power distribution vehicle, preventing damage and safety hazards to the cables 4. Meanwhile, the cable reel 3 can conveniently release or retract the cable 4 according to the needs of the electrical equipment, thus improving work efficiency.

[0034] It should be noted that in the daily use of the power distribution vehicle, simply relying on the outer shell of the power distribution box for protection poses safety hazards. Specifically, the outer shell of the power distribution box can be deformed by being struck by flying stones, and the insulation layer of some cables connected to the power distribution box can be aggravated by flying stones, even causing unstable connections. Therefore, it is necessary to install a protective cabinet 2 to further protect the power distribution box and improve its safety performance.

[0035] See Figures 1-3 As shown, in some embodiments, the top of the protective cabinet 2 is provided with a cable guide frame 5, and the cable 4 stored in the cable reel 3 passes through the cable guide frame 5 before being connected to the electrical equipment.

[0036] Specifically, the cable guide frame 5 is located on top of the protective cabinet 2. In practical applications, there is often a certain height difference between the electrical equipment and the power distribution vehicle. The design of the cable guide frame 5 can effectively shorten this height difference, ensuring that the connection between the cable 4 and the electrical equipment remains stable during the use of the power distribution vehicle. The cable guide frame 5 requires the cable 4 to pass through its interior before connecting to the electrical equipment. This layout not only standardizes the routing of the cable 4 but also effectively prevents the cable 4 from deviating at a large angle, thus avoiding the cable 4 getting caught on obstacles and affecting the stability of the electrical connection.

[0037] See Figures 1-3 As shown, in some embodiments, a height adjustment member 6 is provided between the cable guide frame 5 and the top of the protective cabinet 2. The height adjustment member 6 is used to adjust the distance between the cable guide frame 5 and the protective cabinet 2 in the height direction.

[0038] Specifically, the height adjustment component 6 allows for flexible adjustment of the height distance between the cable guide frame 5 and the protective cabinet 2 based on the height difference between the electrical equipment and the distribution vehicle. This flexibility ensures that the cable 4 can pass through the cable guide frame 5 at the most suitable angle and position to connect with the electrical equipment, avoiding problems such as cable 4 pulling, twisting, or snagging on obstacles due to height mismatch. Furthermore, by precisely adjusting the height of the cable guide frame 5, it ensures that the cable 4 maintains a stable posture during connection, reducing safety hazards caused by cable 4 offset or swaying. In addition, a stable cable 4 connection helps improve the reliability of electrical connections and reduces the risk of circuit failures due to poor contact. The design of the height adjustment component 6 makes the cable guide frame 5 suitable for electrical equipment of different heights and different construction environments.

[0039] See Figures 1-3 As shown, in some embodiments, the height adjustment component 6 is a height-increasing column, which is located between the cable guide frame 5 and the protective cabinet 2, and the height-increasing column is detachably connected to both the cable guide frame 5 and the protective cabinet 2.

[0040] Specifically, the height-adjusting column 6, with its detachable design, makes height adjustment more convenient. Operators can quickly and easily install or remove the height-adjusting column as needed, thereby achieving precise adjustment of the height of the cable guide frame 5. This convenience improves construction efficiency and reduces the time and labor costs associated with height adjustment.

[0041] In some embodiments, the height adjustment member 6 is an electric telescopic rod, which is located between the cable guide frame 5 and the protective cabinet 2, and the telescopic end of the electric telescopic rod is connected to the cable guide frame 5.

[0042] Specifically, the electric telescopic pole has precise telescopic control capabilities, enabling accurate adjustment of the height of the cable guide frame 5. Driven electrically, operators can easily adjust the telescopic length of the pole via a control panel or remote control, thus achieving automated adjustment of the cable guide frame 5's height.

[0043] See Figures 1-3 As shown, in some embodiments, the cable guide frame 5 includes a first side plate 51, a second side plate 52, a first roller 53 and a second roller 54. The first roller 53 and the second roller 54 are both disposed between the first side plate 51 and the second side plate 52. The first roller 53 and the second roller 54 are arranged in parallel, and there is a gap between the first roller 53 and the second roller 54. The cable 4 passes through the gap between the first roller 53 and the second roller 54.

[0044] Specifically, as cable 4 moves within the guide frame, the first roller 53 and the second roller 54 rotate accordingly. This dynamic adaptation ensures the smooth passage of cable 4 within the guide frame. Compared to a fixed structure, the rotation of the first roller 53 and the second roller 54 significantly reduces the risk of cable 4 getting stuck or obstructed. Furthermore, the roller rotation design effectively avoids tension or torque on cable 4 caused by obstruction, reducing the possibility of cable 4 breaking or being damaged, thereby improving the safety of the entire power system. In addition, the contact between the rollers and cable 4 is rolling friction. Compared to sliding friction, rolling friction has less resistance and significantly reduces wear on the cable 4's insulation layer. This helps extend the service life of cable 4 and reduces circuit failures caused by insulation damage.

[0045] See Figures 1-3 As shown, in some embodiments, the top of the protective cabinet 2 is provided with a structural frame, which includes a heightening rod 71 and a diagonal brace 72. The heightening rod 71 is fixedly connected to the top surface of the protective cabinet 2, and one end of the diagonal brace 72 is connected to the top of the heightening rod 71, and the other end is connected to the top surface of the protective cabinet 2.

[0046] Specifically, the structural frame is connected to the top surface of the protective cabinet 2 via the extension rod 71 and the diagonal brace 72, forming a triangular structure. Based on the principle of the stability of a triangle, this structure can significantly improve the stability and load-bearing capacity of the top of the protective cabinet 2.

[0047] Based on the structural frame, heightening columns or electric telescopic rods are installed on the top surface of the structural frame.

[0048] See Figures 1-3 As shown, in some embodiments, the protective cabinet 2 is provided with multiple protective mesh windows 22.

[0049] Specifically, the primary function of the protective mesh window 22 is to provide physical protection, effectively preventing external objects from entering the protective cabinet 2, thereby protecting the equipment and cables 4 inside from damage. The protective mesh window 22 allows air to circulate freely inside and outside the protective cabinet 2, effectively reducing the temperature inside and preventing equipment damage due to overheating. Furthermore, the protective mesh window 22 allows operators to directly observe the internal status of the protective cabinet 2. They can observe the equipment's operating status, indicator light flashing, and any abnormalities through the mesh window, allowing for timely detection and handling of problems.

[0050] See Figure 4 As shown, in some embodiments, the frame body 1 has a first hook 11 and a second hook 12 at the end on the side where the cable reel 3 is set, and there is a gap between the first hook 11 and the second hook 12.

[0051] Specifically, the first hook 11 and the second hook 12 can provide a winding structure for the external cable that supplies power to the power distribution vehicle. Operators can easily wind redundant external cables around the first hook 11 and the second hook 12, thereby achieving effective management of the external cables. This can significantly reduce the dragging and trampling of the cable 4 on the construction site, thereby reducing the risk of damage to the cable 4 caused by external forces.

[0052] This utility model also provides a power distribution vehicle, including the power distribution vehicle frame described above.

[0053] Specifically, by installing the distribution box in a dedicated protective cabinet 2, damage to the distribution box from the complex environment of the construction site, such as flying stones and impacts, is effectively prevented, thus preventing deformation caused by flying stones and ensuring the safe and stable operation of the power distribution vehicle. The height adjustment component 6 (elevator column or electric telescopic rod) between the cable guide frame 5 and the top of the protective cabinet 2 allows for flexible adjustment of the height of the cable guide frame 5 according to the height difference between the electrical equipment and the power distribution vehicle, enhancing the adaptability of the power distribution vehicle to different construction environments and differences in the height of electrical equipment.

[0054] 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.
