Description

Technical Field

[0001] The present invention relates to the technical field of construction equipment, and in particular to a power distribution vehicle for construction machinery. Background Art

[0002] With the increasing awareness of environmental protection and the advancement of technology, more and more heavy equipment are beginning to use electricity as the main power source. This change not only helps to reduce noise pollution and air pollution at construction sites, but also improves energy efficiency and reduces operating costs. However, in actual application, for some heavy equipment that needs to be moved frequently, such as excavators and pile drivers, their power supply methods face a series of challenges.

[0003] In the traditional working mode, powering these mobile heavy equipment usually means using long-distance cables to connect directly to fixed power points, but there are significant safety hazards in actual operation. First, due to the complex and changeable environment of the construction site, the ground may be covered with various obstacles, which makes it easy for the wires set by mopping the ground to get caught or damaged, causing power outages and even safety accidents. Secondly, when the equipment moves significantly, long-term dragging may cause the cable to be over-stretched or twisted, which in turn affects the service life and safety of the cable. In addition, the cable laying and recycling process is time-consuming and labor-intensive, which increases the difficulty and time cost of the operation.

[0004] Alternatively, a fixed column is set at the construction site, and the cable reel is set on the fixed column. The height of the fixed column is used to solve the problem of cable dragging on the ground. However, when using the fixed column method, the movement of the heavy equipment is also restricted, reducing the scope of application of the heavy equipment. Summary of the invention

[0005] In order to overcome at least one of the defects of the prior art described above, the present invention provides a construction machinery power distribution vehicle, which not only meets the needs of mobile construction of heavy equipment, but also meets the needs of preventing cables from dragging on the ground.

[0010] Wherein, the first frame is rotatably connected to the second frame so that the first frame can rotate relative to the second frame.

[0011] Furthermore, the protection cabinet is arranged on one side of the first frame, the cable reel is arranged on the other side of the first frame, and the cable bracket is arranged on the top of the protection cabinet.

[0012] Furthermore, a height-raising member is provided between the protection cabinet and the cable bracket, one end of the height-raising member is detachably connected to the protection cabinet, and the other end of the height-raising member is detachably connected to the cable bracket.

[0013] Furthermore, it also includes an alarm device, the cable reel has a cable remaining length metering module for monitoring the remaining length of the cable on the cable reel, and the alarm device is electrically connected to the cable remaining length metering module so that when the remaining cable on the cable reel is insufficient, the alarm device will sound an alarm.

[0014] Furthermore, the second frame is provided with a transfer arm, one end of which is rotatably connected to the second frame so that the transfer arm can be rotated upward or downward relative to the height direction of the second frame, and the other end of the transfer arm is provided with a connecting piece for connecting the second frame to an external power device through the connecting piece of the transfer arm.

[0015] Furthermore, the transfer arm includes a first transfer arm and a second transfer arm, one end of the second transfer arm is provided with a slide groove, and the other end is rotatably connected to the second frame, one end of the first transfer arm is slidably arranged in the slide groove, and the other end is provided with a connecting piece.

[0016] Furthermore, the cable support comprises:

[0017] first side panel;

[0018] a second side panel, wherein the first side panel and the second side panel are arranged opposite to each other;

[0019] A first roller, two ends of which are rotatably mounted to the first side plate and the second side plate respectively, so that the first roller can rotate around its own axis;

[0020] a second roller, wherein two ends of the second roller are rotatably mounted to the first side plate and the second side plate respectively, so that the second roller can rotate around its own axis, and the first roller is parallel to the second roller;

[0021] a third roller, the third roller being rotatably mounted on a side of the first side plate facing the second side plate and arranged in a vertical direction so that the third roller can rotate around its own axis;

[0022] a fourth roller, the fourth roller being rotatably mounted on a side of the second side plate facing the first side plate and arranged in a vertical direction so that the fourth roller can rotate around its own axis;

[0023] There is a gap between the first roller and the second roller, the first side plate, the first roller, the second side plate and the second roller form the cable channel for the cable to pass through, and the third roller and the fourth roller are located on the same side of the first roller.

[0024] Furthermore, the cable holder also includes a fifth roller, one end of which is rotatably connected to the first side plate, and the other end of which is rotatably connected to the second side plate, so that the fifth roller can rotate around its own axis, and the fifth roller is arranged on the side of the third roller away from the first roller.

[0025] Further, a first stopper is provided on a side of the first frame facing the second frame, so that the first stopper moves with the first frame, and two second stoppers are provided on a side of the second frame facing the first frame, and both of the two second stoppers are located on a movement track of the first stopper.

[0026] Furthermore, two second stoppers are symmetrically arranged on both sides of the first stopper with a line between the first stopper and the rotation axis of the first frame as a symmetry axis.

[0027] In summary, the engineering machinery power distribution vehicle provided by the present invention has the following technical effects:

[0028] 1. The first frame is provided with a cable reel and a cable bracket. The cable reel is used to coil the cable, and the cable bracket is provided with a cable channel for the cable to pass through. This design ensures that the cable does not directly touch the ground, avoiding the risk of the cable being damaged by dragging on the ground. In addition, the cable reel automatically retracts and releases the cable, ensuring that the cable always maintains appropriate tension and does not touch the ground, reducing the physical damage of the cable caused by dragging. At the same time, the existence of the cable bracket provides additional support for the cable, reduces the possibility of excessive bending of the cable, and further protects the structural integrity of the cable.

[0029] 2. The second frame is equipped with multiple wheels, all of which are located on both sides of the second frame, so that the entire distribution vehicle can be moved conveniently. Compared with the fixed column form, this structure is not restricted by position and can adjust the position of the distribution vehicle at any time according to actual needs, greatly expanding the range of action of electrical equipment and adapting to more different terrains.

[0030] 3. The first frame is rotatably connected to the second frame, so that the first frame can rotate relative to the second frame, which can improve the angle adjustment ability of the distribution vehicle when it moves with the electrical equipment, so that the distribution vehicle can flexibly deal with uneven ground or obstacles in complex environments, greatly reducing the risk of wheel jamming or rollover.

[0031] 4. The protective cabinet provides a solid shell for the distribution box, which can effectively prevent damage to the distribution box caused by flying rocks, collisions and other accidents common on construction sites. This extra protection is particularly important in scenes with complex working environments and many potential dangerous factors. By introducing the cables into the protective cabinet and managing them through the cable guide frame, the risk of cables being exposed to the outside can be reduced, and the possibility of cable wear or breakage caused by external interference can be reduced.

Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] In order to facilitate the understanding of the embodiments of the present invention, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present invention.

[0046] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0048] See also Figure 1-Figure 11 The present invention discloses an engineering machinery power distribution vehicle, including a first frame 1 and a second frame 2. The first frame 1 is provided with a protective cabinet 11, a cable reel 12 and a cable support 13. The protective cabinet 11 has a cavity for installing a power distribution box. The cable reel 12 is used to coil a cable 4. The cable support 13 is provided with a cable channel for the cable 4 to pass through. The cable 4 passes through the cable channel. The second frame 2 is equipped with a plurality of wheels 21, and all the wheels 21 are arranged on both sides of the second frame 2. The first frame 1 is rotatably connected with the second frame 2 so that the first frame 1 can rotate relative to the second frame 2.

[0049] Specifically, the protective cabinet 11 is arranged on one side of the first frame 1, and a cavity for installing the distribution box is provided inside. The protective cabinet 11 not only provides physical protection for the distribution box to prevent it from being affected by the complex environment of the construction site (such as flying stones, impact, etc.), but also facilitates the staff to carry out daily maintenance and inspection by setting a cabinet door 111. The cable reel 12 is located on the other side of the first frame 1 away from the protective cabinet 11, and is used to coil the cable 4. The cable bracket 13 is provided with a cable channel for the cable 4 to pass through. The second frame 2 is equipped with a plurality of wheels 21, and all wheels 21 are arranged on both sides of the second frame 2, ensuring the stability and mobility of the vehicle. The design of the wheel 21 allows the entire distribution vehicle to travel smoothly on uneven ground and adapt to complex construction environments. The first frame 1 is rotatably connected to the second frame 2, allowing the first frame 1 to rotate relative to the second frame 2, so that the distribution vehicle can flexibly adjust its own angle to adapt to the changes in the working orientation of the electrical equipment, especially on uneven ground or in complex environments, greatly reducing the possibility of the wheel 21 encountering obstacles or falling into a pit, and reducing the risk of rollover.

[0050] See also Figure 1 and Figure 2 As shown, in some embodiments, the protection cabinet 11 is disposed on one side of the first frame 1 , the cable reel 12 is disposed on the other side of the first frame 1 , and the cable support 13 is disposed on the top of the protection cabinet 11 .

[0051] Specifically, the protection cabinet 11 is arranged on one side of the first frame 1. This arrangement ensures that the distribution box in the protection cabinet 11 can be fully protected while leaving enough space for other components. The cable reel 12 is arranged on the other side of the first frame 1 away from the protection cabinet 11. This layout helps to balance the center of gravity distribution of the entire frame. The cable bracket 13 is arranged on the top of the protection cabinet 11, which enables the distribution vehicle to make full use of the vertical space, further increase the suspension height of the cable 4, reduce the chance of the cable 4 contacting the ground, and thus reduce the risk of damage to the cable 4.

[0052] See also Figure 1 and Figure 2As shown, as an option, when the second frame 2 is provided with a transfer arm 22, and the heavier cable reel is located on a side away from the transfer arm 22, the hill-crossing performance of the vehicle is improved.

[0053] See also Figure 1 and Figure 2 As shown, as an option, a plurality of protective mesh windows 112 can be provided on the protective cabinet 11 to allow free circulation of air, thereby effectively reducing the internal temperature of the protective cabinet 11 and preventing the equipment from being damaged due to overheating; at the same time, it also allows the operator to intuitively observe the internal status of the protective cabinet 11.

[0054] See also Figure 1 and Figure 2 As shown, in some embodiments, a heightening member 14 is provided between the protection cabinet 11 and the cable bracket 13 , and one end of the heightening member 14 is detachably connected to the protection cabinet 11 , and the other end is detachably connected to the cable bracket 13 .

[0055] Specifically, the existence of the height-raising member 14 allows the height of the cable support 13 to be flexibly adjusted according to actual construction requirements. For example, when switching between electrical equipment at different heights, or when dealing with complex and changeable terrain conditions at the construction site, the operator can quickly and easily install or remove the height-raising member 14, thereby achieving precise adjustment of the height of the cable 4 guide frame.

[0056] The connection between the height-increasing member 14 and the protective cabinet 11 and the cable bracket 13 is detachable, which can be bolted, latched or other similar mechanical connection methods. Such a design ensures the safety and reliability of the connection, facilitates quick assembly and disassembly, and improves work efficiency.

[0057] Furthermore, the height-increasing member 14 may be a height-increasing column, or a more intelligent automatic telescopic device, and the cable bracket 13 is mounted on the mobile end of the automatic telescopic device, and then the automatic telescopic device drives the cable bracket 13 to be dynamically adjusted to flexibly adapt to more environments. The automatic telescopic device may be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod, etc., which may be selected according to the design requirements of the environment and structure, and is not limited here.

[0058] In addition, since the height-raising member 14 is detachably connected, the cable support 13 can be lowered to the lowest position when the distribution vehicle is not in operation (such as during transportation or long-term storage), thereby reducing the overall height, facilitating transportation and saving space.

[0059] The height increasing member 14 not only increases the height, but also enhances the overall stability of the top structure of the protective cabinet 11. By forming an additional support point, it helps disperse the influence of the tension from the cable 4 and other external forces, ensuring the firmness and durability of the entire system.

[0060] See also Figure 1 and Figure 2 As shown, in some embodiments, the distribution vehicle also includes an alarm device 3, and the cable reel 12 has a cable remaining length metering module for monitoring the remaining length of the cable 4 on the cable reel 12. The alarm device 3 is electrically connected to the cable remaining length metering module so that when the remaining cable 4 on the cable reel 12 is insufficient, the alarm device 3 will sound an alarm.

[0061] Specifically, the distribution vehicle also includes an alarm device 3, which is electrically connected to the cable remaining length metering module on the cable reel 12, wherein the cable remaining length metering module is used to monitor the actual remaining length of the cable 4 on the cable reel 12 in real time. It accurately measures the winding amount of the cable 4 through sensors or other detection means, and transmits the data to the alarm device 3. The alarm device 3 receives the data signal from the cable remaining length metering module. Once it detects that the remaining length of the cable 4 is lower than the preset safety threshold, it will immediately start the alarm program to prevent the cable 4 from being broken. This can be an audible and visual alarm (such as a buzzer plus an LED indicator light), or it can be an information notification sent to a remote monitoring terminal via wireless communication. The specific alarm threshold of the alarm device 3 can define a reasonable cable 4 remaining length threshold according to the actual application scenario, for example, an alarm is triggered when there are only the last two turns of the cable 4.

[0062] See also Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, in some embodiments, the second frame 2 is provided with a transfer arm 22, one end of the transfer arm 22 is rotatably connected to the second frame 2 so that the transfer arm 22 can be rotated upward or downward relative to the height direction of the second frame 2, and the other end of the transfer arm 22 is provided with a connecting piece 23 for connecting the second frame 2 to an external power device through the connecting piece 23 of the transfer arm 22.

[0063] Specifically, the transfer arm 22 can be rotatably connected relative to the second frame 2, that is, the transfer arm 22 is allowed to rotate up and down relative to the height direction of the second frame 2, and can be flexibly connected to connection points at different heights, greatly expanding the distribution vehicle's support capabilities for different types of heavy equipment.

[0064] See also Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, in some embodiments, the transfer arm 22 includes a first transfer arm 221 and a second transfer arm 222, one end of the second transfer arm 222 is provided with a slide groove 251, and the other end is rotatably connected to the second frame 2, one end of the first transfer arm 221 is slidably arranged in the slide groove 251, and the other end is provided with a connecting member 23.

[0065] Specifically, the transfer arm 22 is composed of a first transfer arm 221 and a second transfer arm 222, and the other end is rotatably connected to the second frame 2. The existence of the slide slot 251 allows the first transfer arm 221 to be extended or shortened as needed, thereby adjusting the overall length to ensure that various types of heavy equipment can be stably connected. Specifically, there are often ups and downs on the construction site, or when heavy equipment is moved, the relative height between the heavy equipment and the ground will constantly change. Through the sliding adjustment of the first transfer arm 221 in the slide slot 251, it can be ensured that the transfer arm 22 is extended outward and the overall length is extended, so that the transfer arm 22 can be rotated upward at a smaller angle relative to the second frame 2 to adapt to a larger height difference and maintain the stability of the overall posture of the distribution vehicle.

[0066] See also Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, as an option, the transfer arm 22 also includes an adjustment limit structure, which includes a limit pin 26, a first limit hole 2221 and a second limit hole 2211. The first limit hole 2221 is provided on the second transfer arm 222 and passes through the slide groove 251. There are multiple second limit holes 2211, and all of the second limit holes 2211 are provided on the first transfer arm 221 toward the side of the first limit hole 2221, so that when the limit pin 26 passes through the first limit hole 2221 and one of the second limit holes 2211 at the same time, the relative sliding of the first transfer arm 221 and the second transfer arm 222 is limited.

[0067] Specifically, the operator only needs to simply adjust the position of the first transfer arm 221, find the appropriate second limit hole 2211, and use the limit pin 26 to fix it, so as to quickly complete the docking with connection points at different heights. This method greatly simplifies the operation process, reduces preparation time, and improves work efficiency. In addition, during the movement of the equipment, the automated cable 4 management function reduces the need for manual intervention and further improves construction efficiency.

[0068] Optionally, all the second limiting holes 2211 are arranged at equal intervals along the sliding direction of the first transfer arm 221 .

[0069] Specifically, all the second limiting holes 2211 are arranged at equal intervals along the sliding direction of the first transfer arm 221, so that the operator can adjust the height of the connection point of different types of heavy equipment with fixed steps. This not only provides precise height adjustment, but also ensures the consistency and predictability of each adjustment, thereby improving the accuracy and reliability of the connection.

[0070] See also Figure 4-Figure 6As shown, as an option, the first transfer arm 221 is provided with a traction ring 2212 at one end of the connecting member 23 , and the connecting member 23 and the traction ring 2212 are penetrated by a first connecting pin 2213 so that the connecting member 23 can rotate around the first connecting pin 2213 .

[0071] Specifically, the traction ring 2212 is designed to be conveniently connected to vehicles such as trucks and cars. This allows the distribution vehicle to be not only towed by heavy equipment, but also transported by more common trucks or cars to achieve rapid movement and transfer. This design greatly expands the application scenarios of the distribution vehicle, allowing it to play a role in a variety of working environments.

[0072] The connector 23 is used to connect with heavy equipment such as excavators and pile drivers. This special connector 23 ensures stable docking with a specific type of heavy equipment, and improves the reliability and safety of the connection.

[0073] The first connecting pin 2213 passes through the connecting piece 23 and the traction ring 2212, so that the connecting piece 23 can be easily disassembled. This design allows the operator to quickly switch the connection mode according to actual needs, whether using the connecting piece 23 to connect heavy equipment or using the traction ring 2212 to connect a truck or a car, it can achieve fast and easy operation. This not only reduces preparation time, but also improves work efficiency.

[0074] Since both the traction ring 2212 and the connecting member 23 can rotate around the first connecting pin 2213, when the heavy equipment is connected to the first transfer arm 221 through the connecting member 23, the heavy equipment simply turns, and the connecting member 23 and the traction ring 2212 can also achieve a smoother rotation transition through the rotation relationship between the two, thereby improving the stability of the frame during movement.

[0075] See also Figure 4-Figure 6 As shown, as an option, the second transfer arm 222 includes a slide tube 25, a first fork arm 2222 and a second fork arm 2223. The slide tube 25 is provided with a cavity that runs through the slide tube 25, and the cavity constitutes a slide groove 251. The second frame 2 is provided with a first rotating connection member 27 and a second rotating connection member 28 on both sides facing the second transfer arm 222. One end of the first fork arm 2222 is fixedly connected to the side wall of the slide tube 25, and the other end is rotatably connected to the first rotating connection member 27. The second fork arm 2223 is provided on the side of the slide tube 25 opposite to the first fork arm 2222, and is fixedly connected to the slide tube 25, and the other end is rotatably connected to the second rotating connection member 28.

[0076] Specifically, the first fork arm 2222 is rotatably connected to the first rotating connector 27. The first rotating connector 27 can be rotatably connected to the first rotating connector 27 by passing the first fork arm 2222 through a rotating shaft, or can be rotatably connected through other structures, which are not limited here. Similarly, the second fork arm 2223 is rotatably connected to the second rotating connector 28. The second rotating connector 28 can be rotatably connected to the second rotating connector 28 by passing the second fork arm 2223 through a rotating shaft, or can be rotatably connected through other structures, which are not limited here. The first fork arm 2222 is rotatably connected to the first rotating connector 27, and the second fork arm 2223 is rotatably connected to the second rotating connector 28, forming two rotating connection points. The two rotating connection points are respectively arranged on both sides of the second frame 2, so that the movement of the transfer arm 22 at different heights and angles is more stable, thereby improving the overall stability. That is, the setting of the two rotating connection points makes the force more uniform, reduces the structural deformation or damage caused by excessive force on a single point, and thus prolongs the service life of the frame.

[0077] See also Figure 4-Figure 6 As shown, as an option, the second transfer arm 222 also includes a connecting rod 2224, one end of which is fixedly connected to the first fork arm 2222 close to the first rotating connecting member 27, and the other end is fixedly connected to the second fork arm 2223 close to the second rotating connecting member 28.

[0078] Specifically, the addition of the connecting rod 2224 further enhances the structural stability of the transfer arm 22. The two ends of the connecting rod 2224 are respectively fixedly connected to the first fork arm 2222 and the second fork arm 2223, forming a stable triangular structure, effectively reducing the shaking and deformation of the transfer arm 22 during movement, and ensuring the reliability of the connection.

[0079] See also Figure 4-Figure 6 As shown, further, the first fork arm 2222 and the second fork arm 2223 are symmetrically arranged on both sides of the sliding tube 25 with the sliding direction of the first transfer arm 221 as a symmetry axis.

[0080] Specifically, the first fork arm 2222 and the second fork arm 2223 are symmetrically arranged on both sides of the slide tube 25 with the sliding direction of the first transfer arm 221 as the symmetry axis. This symmetrical design makes the movement of the transfer arm 22 at different heights and angles more balanced and stable. The symmetrical structural distribution ensures the uniformity of force, reduces structural deformation or damage caused by excessive force on one side, and thus improves the overall stability.

[0081] See also Figure 4-Figure 6As shown, as an option, the second transfer arm 222 also includes a first diagonal support rod 2225 and a second diagonal support rod 2226, one end of the first diagonal support rod 2225 is fixedly connected to the middle part of the first fork arm 2222, and the other end is fixedly connected to the middle part of the pull rod 2224, one end of the second diagonal support rod 2226 is fixedly connected to the middle part of the second fork arm 2223, and the other end is fixedly connected to the middle part of the pull rod 2224.

[0082] See also Figure 4-Figure 6 As shown, specifically, the addition of the first diagonal brace 2225 and the second diagonal brace 2226 forms multiple support points, making the structure of the transfer arm 22 more stable. The connection points of these diagonal braces, the first fork arm 2222, the second fork arm 2223 and the tie rod 2224 form multiple triangular structures, which effectively disperse the force, reduce local stress concentration, and improve the overall stability.

[0083] See also Figure 4-Figure 6 As shown, further, the first oblique support rod 2225 and the second oblique support rod 2226 are symmetrically arranged on both sides of the sliding tube 25 with the sliding direction of the first transfer arm 221 as the symmetry axis.

[0084] Specifically, the first diagonal brace 2225 and the second diagonal brace 2226 are symmetrically arranged on both sides of the slide tube 25 with the sliding direction of the first transfer arm 221 as the symmetry axis. This symmetrical design makes the movement of the transfer arm 22 at different heights and angles more balanced and stable, ensures the uniformity of force, reduces structural deformation or damage caused by excessive force on one side, and thus improves the overall stability.

[0085] See also Figure 1-3As shown, in some embodiments, the cable support 13 includes a first side plate 130, a second side plate 131, a first roller 132, a second roller 133, a third roller 134 and a fourth roller 135, and the first side plate 130 and the second side plate 131 are arranged opposite to each other. The two ends of the first roller 132 are respectively rotatably assembled to the first side plate 130 and the second side plate 131, so that the first roller 132 can rotate around its own axis. The two ends of the second roller 133 are respectively rotatably assembled to the first side plate 130 and the second side plate 131, so that the second roller 133 can rotate around its own axis, and the first roller 132 is parallel to the second roller 133. The third roller 134 is rotatably mounted on a side of the first side plate 130 facing the second side plate 131, and is arranged in the vertical direction, so that the third roller 134 can rotate around its own axis. The fourth roller 135 is rotatably mounted on a side of the second side plate 131 facing the first side plate 130 and is arranged in a vertical direction so that the fourth roller 135 can rotate around its own axis. There is a gap between the first roller 132 and the second roller 133. The first side plate 130, the first roller 132, the second side plate 131 and the second roller 133 are surrounded to form a cable channel for the cable 4 to pass through. The third roller 134 and the fourth roller 135 are located on the same side of the first roller 132.

[0086] Specifically, the cable support 13 is composed of a first side plate 130 and a second side plate 131. The first side plate 130 and the second side plate 131 are arranged opposite to each other with a gap therebetween, so that each roller can be installed between the first side plate 130 and the second side plate 131, and a certain range is provided for the deflection of the cable 4. The two ends of the first roller 132 and the second roller 133 are respectively rotatably assembled on the first side plate 130 and the second side plate 131, so that the two rollers can rotate freely around their own axes. The first roller 132 and the second roller 133 are placed in parallel, and a certain gap is maintained between the two. The gap is used for the cable 4 to pass through, which not only ensures that the cable 4 can move smoothly between the first roller 132 and the second roller 133, but also allows the cable 4 to perform rolling friction rather than sliding friction during its extension or recovery process, thereby reducing the risk of the cable 4 getting stuck during movement and reducing the wear on the insulation layer of the cable 4. The third roller 134 is mounted on the side of the first side plate 130 facing the second side plate 131, and the fourth roller 135 is mounted on the side of the second side plate 131 facing the first side plate 130, and both are arranged in the vertical direction. This structure can adapt to the angle change of the cable 4 relative to the bracket, which may occur when the electrical equipment moves. Since the third roller 134 and the fourth roller 135 can rotate around their own axes, when the cable 4 contacts the third roller 134 or the fourth roller 135, it can roll along the surface of the third roller 134 or the fourth roller 135, avoiding the jamming phenomenon caused by hard contact.

[0087] See also Figure 1-3 As shown, in some embodiments, the cable support 13 also includes a fifth roller 136, one end of the fifth roller 136 is rotatably connected to the first side plate 130, and the other end is rotatably connected to the second side plate 131, so that the fifth roller 136 can rotate around its own axis, and the fifth roller 136 is arranged on the side of the third roller 134 away from the first roller 132.

[0088] Specifically, the fifth roller 136 is arranged on the side of the third roller 134 away from the first roller 132. Since the cable holder 13 is usually installed on the top of the distribution vehicle, the cable 4 generally does not encounter obstacles when rotating upward, while the downward rotation may be restricted by other components of the distribution vehicle (such as the body structure, the distribution cabinet, etc.). By setting the fifth roller 136 on the side away from the third roller 134, when the cable 4 rotates downward relative to the cable holder 13, the cable 4 can change direction after contacting the fifth roller 136, which allows the cable 4 to smoothly pass the fifth roller 136 and then adjust the direction, thereby avoiding interference with the components of the distribution vehicle itself.

[0089] Furthermore, the fifth roller 136 can rotate freely around its own axis, and even if the cable 4 is subjected to pressure or produces an angle change during the direction change process, it can ensure that the cable 4 rolls smoothly, greatly reducing the probability of the cable 4 being stuck. In addition, by providing a rotating contact surface for the cable 4, the wear on the insulation layer of the cable 4 is reduced, thereby protecting the integrity and service life of the cable 4.

[0090] See also Figure 1-3 As shown, as an option, the cable holder 13 also includes a sixth roller 137 and a seventh roller 138, the sixth roller 137 is rotatably mounted on the first side plate 130, and the third roller 134 and the sixth roller 137 are symmetrically arranged with the axis of the first roller 132 as the axis of symmetry; the seventh roller 138 is rotatably mounted on the second side plate 131, and the fourth roller 135 and the seventh roller 138 are symmetrically arranged with the axis of the first roller 132 as the axis of symmetry.

[0091] Specifically, under some extreme conditions, there is a situation where the cable 4 at the rear of the cable support 13 contacts the first side plate 130 or the second side plate 131, and the sixth roller 137 is rotatably mounted on the first side plate 130, and is symmetrically arranged with the third roller 134 with the axis of the first roller 132 as the axis of symmetry. The seventh roller 138 is rotatably mounted on the second side plate 131, and is symmetrically arranged with the fourth roller 135 with the axis of the first roller 132 as the axis of symmetry. The existence of the sixth roller 137 and the seventh roller 138 increases the contact points between the cable 4 and the support, so that the cable 4 has more support points to choose from when a large angle change occurs, reducing the risk of the cable 4 being stuck or entangled.

[0092] Optionally, in order to improve the adaptation effect of the cable holder 13, the cable holder 13 also includes an eighth roller 139, one end of the eighth roller 139 is rotatably assembled on the first side plate 130, and the other end is rotatably assembled on the second side plate 131, and the fifth roller 136 and the eighth roller 139 are symmetrically arranged with the axis of the first roller 132 as the axis of symmetry.

[0093] See also Figure 7-Figure 11 As shown, in some embodiments, a first stopper 15 is provided on the side of the first frame 1 facing the second frame 2 so that the first stopper 15 moves with the first frame 1 , and two second stops 24 are provided on the side of the second frame 2 facing the first frame 1 , and both second stops 24 are located on the movement trajectory of the first stopper 15 .

[0094] Specifically, the first stopper 15 is installed on the first frame 1, rotates with the first frame 1, and is located on the side of the first frame 1 facing the second frame 2, that is, the surface opposite to the first frame 1 and the second frame 2. Two second stoppers 24 are respectively installed on the side of the second frame 2 facing the first frame 1, and the two second stoppers 24 are both located on the movement track of the first stopper 15. Therefore, when the first stopper 15 rotates clockwise or counterclockwise with the first frame 1, it will abut against one of the second stoppers 24 and limit the rotation of the first frame 1, thereby effectively limiting the maximum rotation angle of the first frame 1 relative to the second frame 2, thereby preventing the first frame 1 from rotating excessively, thereby avoiding the problem of the cable 4 being entangled.

[0095] See also Figure 7-10 As shown, further, the two second stoppers 24 are symmetrically arranged on both sides of the first stopper 15 with the line between the first stopper 15 and the rotation axis of the first frame 1 as the symmetry axis.

[0096] Specifically, since the two second stoppers 24 are symmetrically arranged, when the first frame 1 rotates in any direction, the first stopper 15 will first contact a second stopper 24 and stop further rotation. This symmetrical arrangement ensures that when placing the rotating frame, the construction personnel can relatively accurately determine the rotation range of the first frame 1, so as to place the rotating frame in advance at a position with sufficient rotation space.

[0097] See also Figure 7-10 As shown, as an option, with the rotation axis of the first frame 1 as the center of the circle, the central angle formed by the line connecting the first stopper 15 to the rotation axis and the line connecting any second stopper 24 to the rotation axis is 90 degrees.

[0098] Specifically, when the rotation angle of the first frame 1 relative to the second frame 2 is kept within a certain range, the center of gravity of the entire system is relatively stable, that is, the center of gravity is biased toward the position of the cable reel 12 with a larger deadweight. In this case, even if the ground is slightly uneven, the distribution vehicle can still maintain a good balance. Once the rotation angle exceeds this range, the position of the cable reel 12 on the first frame 1 will be greatly displaced relative to the second frame 2. If the construction workers fail to consider this impact in advance, rollover may occur.

[0099] See also Figure 7-10 As shown, as an option, the first frame 1 and the second frame 2 can be rotatably connected via a rotating member 5. The rotating member 5 can be a slewing bearing or a simple rotating shaft structure, which is not limited here, and can enable the first frame 1 to rotate relative to the second frame 2.

[0100] See also Fig.11 As shown, as an option, the first frame 1 is provided with a first hook 16 and a second hook 17 at the end portion of the first frame 1 on the side where the cable reel 12 is provided, and there is a gap between the first hook 16 and the second hook 17 .

[0101] Specifically, the first hook 16 and the second hook 17 can provide a winding structure for the external cables that supply power to the distribution vehicle. The operator can simply wind the redundant external cables around the first hook 16 and the second hook 17, thereby achieving effective organization of the external cables. This can significantly reduce the dragging and stepping on of the external cables at the construction site, thereby reducing the risk of damage to the external cables due to external forces.

[0102] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above-mentioned technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also regarded as the protection scope of the present invention.
