Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of construction equipment, especially relates to a construction machinery power distribution vehicle. BACKGROUND

[0002] With the enhancement of environmental protection consciousness and the progress of technology, more and more heavy equipment begins to use electric energy as the main power source. This change not only helps to reduce noise pollution and air pollution at the construction site, but also can improve energy utilization efficiency and reduce operating costs. However, in the actual application process, for some heavy equipment that needs to be frequently moved, such as excavators, pile drivers, etc., their power supply mode faces a series of challenges.

[0003] In the traditional working mode, power supply for these mobile heavy equipment usually means using long-distance cables to be directly connected to fixed power points, but in actual operation, there are significant safety hazards. First of all, due to the complex and changeable environment of the construction site, the ground may be covered with various obstacles, which can easily cause the power cable to be hung or damaged, causing power failure and even safety accidents. Secondly, when the equipment moves significantly, long-time dragging can cause the cable to be stretched or twisted, thereby affecting the service life and safety of the cable. In addition, the cable laying and recycling process is time-consuming and labor-intensive, increasing the difficulty and time cost of the work.

[0004] Alternatively, fixed columns are set up at the construction site, and cable reels are set up on the fixed columns, which use the height of the fixed columns to solve the problem of cable dragging on the ground. However, the use of fixed columns limits the movement of heavy equipment, reducing the application range of heavy equipment. SUMMARY

[0028] 1. The first frame is provided with a cable reel and a cable support, the cable reel is used for winding the cable, and the cable support is provided with a cable passage for the cable to pass through. This design ensures that the cable does not directly contact the ground, avoiding the risk of damage to the cable due to mopping the floor. And by automatically winding and unwinding the cable through the cable reel, the cable is always kept at an appropriate tension and does not touch the ground, reducing the physical damage to the cable caused by dragging. At the same time, the existence of the cable support provides additional support for the cable, reducing the possibility of excessive bending of the cable and further protecting the structural integrity of the cable.

The second frame is provided with a plurality of wheels, all of which are arranged on both sides of the second frame, so that the entire power distribution vehicle can be conveniently moved, and compared with the fixed column form, the structure is not limited by position and can adjust the position of the power distribution vehicle at any time according to actual needs, greatly expanding the movement range of the power equipment, and adapting to more different terrains.

[0030] 3. The first frame is rotationally connected with the second frame, so that the first frame can rotate relative to the second frame, which can improve the angle adjustment capability of the power distribution vehicle when following the power equipment to move, so that the power distribution vehicle can flexibly cope with uneven ground or obstacles in complex environments, greatly reducing the risk of wheel jamming or overturning.

[0031] 4. The protection cabinet provides a solid shell for the power distribution box, which can effectively prevent common flying stones, impacts and other accidents on the construction site from causing damage to the power distribution box.

DETAILED DESCRIPTION

[0045] In order to better understand and implement, the technical solutions in the embodiments of the utility model will be described and discussed clearly and completely in combination with the drawings of the utility model. Obviously, only a part of examples of the utility model are described here, and not all examples. Based on the embodiments in the utility model, all other examples obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0046] In order to facilitate the understanding of the embodiments of the utility model, the following will be further explained and described with specific examples as an example in combination with the drawings, and each embodiment does not constitute the limitation of the embodiments of the utility model.

[0047] In the description of the utility model, it is necessary to explain, the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0048] 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 the utility model belongs. The terminology used in the specification of the utility model herein is only for the purpose of describing the specific embodiments and is not intended to limit the utility model.

[0049] Referring to Figures 1-11 The utility model discloses an engineering machinery power distribution car, including first frame 1 and second frame 2, be equipped with protection cabinet 11, cable reel 12 and cable support 13 on first frame 1, the cavity for installing distribution box is had in protection cabinet 11, the side wall of protection cabinet 11 is equipped with a plurality of protective net window 112, cable reel 12 is used for coiling cable 4, cable support 13 is equipped with the cable passageway for cable 4 to pass through, and cable 4 sets up through cable passageway. Second frame 2 is assembled with a plurality of wheels 21, and all wheels 21 are arranged on the both sides of second frame 2. Among them, first frame 1 is rotationally connected with second frame 2, so that first frame 1 can rotate relative to second frame 2.

[0050] Specifically, the protective cabinet 11 is located on one side of the first frame 1, and has an internal cavity for installing the distribution box. The protective cabinet 11 not only provides physical protection for the distribution box, preventing it from being affected by the complex environment of the construction site (such as flying stones, impacts, etc.), but also facilitates daily maintenance and repair by personnel through the 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 wind the cable 4. The cable bracket 13 has a cable channel for the cable 4 to pass through. The second frame 2 is equipped with multiple wheels 21, all located on both sides of the second frame 2, ensuring the stability and mobility of the vehicle. The design of the wheels 21 allows the entire distribution vehicle to travel smoothly on uneven ground, adapting to complex construction environments. The first frame 1 and the second frame 2 are rotatably connected, allowing the first frame 1 to rotate relative to the second frame 2. This allows the distribution vehicle to flexibly adjust its angle to adapt to changes in the working position of the electrical equipment. Especially on uneven ground or in complex environments, this greatly reduces the possibility of the wheels 21 encountering obstacles or getting stuck in potholes, reducing the risk of rollover. The protective mesh window 112 allows air to circulate freely inside and outside the protective cabinet 11, which helps to reduce the internal temperature and prevent the distribution box and other electrical equipment from being damaged due to overheating. Furthermore, through the protective mesh window 112, operators can visually view the inside of the protective cabinet 11 without opening it, which facilitates timely detection of faults and daily inspections and troubleshooting.

[0051] See Figure 1 and Figure 2 As shown, in some embodiments, the protective cabinet 11 is located on one side of the first frame 1, the cable reel 12 is located on the other side of the first frame 1, and the cable bracket 13 is located on the top of the protective cabinet 11.

[0052] Specifically, the protective cabinet 11 is located on one side of the first frame 1. This arrangement ensures that the distribution box inside the protective cabinet 11 is adequately protected while also providing sufficient space for other components. The cable reel 12 is located on the other side of the first frame 1 away from the protective cabinet 11. This layout helps to balance the center of gravity of the entire frame. The cable bracket 13 is located on top of the protective cabinet 11, which allows the power distribution vehicle to make full use of vertical space, further increasing the suspension height of the cable 4 and reducing the chance of the cable 4 contacting the ground, thereby reducing the risk of damage to the cable 4.

[0053] See Figure 1 and Figure 2 As shown, optionally, when the second frame 2 is equipped with an adapter arm 22, and the heavier cable reel is located on the side away from the adapter arm 22, the vehicle's hill-crossing performance is improved.

[0054] See Figure 1 and Figure 2As shown, as an option, the protective cabinet 11 can be optionally provided with multiple protective mesh windows 112, allowing air to flow freely, effectively reducing the internal temperature of the protective cabinet 11 and preventing equipment from being damaged due to overheating; at the same time, it also allows the operator to directly observe the status inside the protective cabinet 11.

[0055] Referring to Figure 1 and Figure 2 As shown, in some embodiments, a height-increasing piece 14 is provided between the protective cabinet 11 and the cable support 13, with one end of the height-increasing piece 14 being detachably connected to the protective cabinet 11 and the other end being detachably connected to the cable support 13.

[0056] Specifically, the presence of the height-increasing piece 14 allows the height of the cable support 13 to be flexibly adjusted according to actual construction needs. For example, when switching between electrical equipment at different heights, or when dealing with complex and variable terrain conditions at the construction site, the operator can quickly and easily install or disassemble the height-increasing piece 14, thereby achieving precise adjustment of the height of the cable guide 4.

[0057] Moreover, the connection between the height-increasing piece 14 and the protective cabinet 11 and the cable support 13 adopts a detachable manner, which can be bolted, locked with a latch, or other similar mechanical connection methods. Such a design not only ensures the safety and reliability of the connection, but also facilitates quick disassembly and assembly, improving work efficiency.

[0058] Further, the height-increasing piece 14 can be a height-increasing column or a more intelligent automatic telescopic device, with the cable support 13 being assembled at the moving end of the automatic telescopic device, and then the cable support 13 being dynamically adjusted by the automatic telescopic device to flexibly adapt to more environments. The automatic telescopic device can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod, and the specific choice can be made according to the design needs of the environment and structure, which is not limited here.

[0059] In addition, since the height-increasing piece 14 adopts a detachable connection method, the power distribution vehicle can lower the cable support 13 to the lowest position in a non-working state (such as transportation or long-term storage), reducing the overall height, facilitating transportation, and saving space.

[0060] The height-increasing piece 14 not only serves to increase 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 to disperse the influence of the cable 4 tension and other external forces, ensuring the firmness and durability of the entire system.

[0061] Referring to Figure 1 and Figure 2As shown, in some embodiments, the power distribution vehicle further comprises an alarm device 3, the cable reel 12 is provided with a cable residual length metering module for monitoring the residual length of the cable 4 on the cable reel 12, and the alarm device 3 is electrically connected with the cable residual length metering module, so that when the residual cable 4 on the cable reel 12 is insufficient, the alarm device 3 will alarm.

[0062] Specifically, the power distribution vehicle further comprises an alarm device 3 electrically connected with the cable residual length metering module on the cable reel 12, wherein the cable residual length metering module is used to monitor the actual residual length of the cable 4 on the cable reel 12 in real time. It accurately measures the winding amount of the cable 4 through a sensor or other detection means, and transmits the data to the alarm device 3. The alarm device 3 receives the data signal from the cable residual length metering module, and starts the alarm program as soon as it detects that the residual length of the cable 4 is lower than the preset safety threshold, so as to prevent the cable 4 from being pulled off. This can be an audible and visual alarm (such as a buzzer plus an LED indicator), or information sent to a remote monitoring terminal through wireless communication. The alarm threshold of the specific alarm device 3 can define a reasonable cable 4 residual length threshold according to the actual application scene, for example, triggering an alarm when there are only two turns of cable 4 left.

[0063] Referring to Figure 1 , Figure 2 , Figures 4-6 As shown, in some embodiments, the second vehicle frame 2 is provided with an adapter arm 22, one end of the adapter arm 22 is rotatably connected with the second vehicle frame 2, so that the adapter arm 22 can rotate upward or downward relative to the height direction of the second vehicle frame 2, and the other end of the adapter arm 22 is provided with a connecting piece 23 for connecting the second vehicle frame 2 with an external power equipment through the connecting piece 23 of the adapter arm 22.

[0064] Specifically, the adapter arm 22 is rotatably connected with the second vehicle frame 2, i.e. allowing the adapter arm 22 to rotate up and down relative to the height direction of the second vehicle frame 2, which can flexibly dock with connecting points of different heights, greatly expanding the support capability of the power distribution vehicle for different types of heavy equipment.

[0065] Referring to Figure 1 , Figure 2 , Figures 4-6 As shown, in some embodiments, the adapter arm 22 comprises a first adapter arm 221 and a second adapter arm 222, one end of the second adapter arm 222 is provided with a sliding groove 251, the other end is rotatably connected with the second vehicle frame 2, one end of the first adapter arm 221 is slidably arranged in the sliding groove 251, and the other end is provided with a connecting piece 23.

[0066] Specifically, the adapter arm 22 is composed of a first adapter arm 221 and a second adapter arm 222, and is rotatably connected to the second vehicle frame 2 at the other end. The existence of the sliding groove 251 allows the first adapter arm 221 to extend or shorten as needed, thereby adjusting the overall length and ensuring stable connection with various types of heavy equipment. Specifically, in the case of fluctuating heights at the construction site, or when the heavy equipment moves, the relative height between the heavy equipment and the ground will change constantly. By adjusting the sliding of the first adapter arm 221 in the sliding groove 251, the adapter arm 22 can be extended to increase the overall length, and then the adapter arm 22 can be rotated upward at a smaller angle relative to the second vehicle frame 2 to adapt to larger height differences and maintain the stability of the overall posture of the power distribution vehicle.

[0067] Referring to Figure 1 , Figure 2 , Figures 4-6 As an option, the adapter arm 22 also includes an adjustment limiting structure, which includes a limiting pin 26, a first limiting hole 2221, and a plurality of second limiting holes 2211. The first limiting hole 2221 is provided on the second adapter arm 222 and extends through the sliding groove 251. The second limiting holes 2211 are provided on the first adapter arm 221 and are arranged on the side facing the first limiting hole 2221. When the limiting pin 26 passes through the first limiting hole 2221 and one of the second limiting holes 2211 at the same time, the relative sliding of the first adapter arm 221 and the second adapter arm 222 is limited.

[0068] Specifically, the operator only needs to simply adjust the position of the first adapter arm 221, find the appropriate second limiting hole 2211, and fix it with the limiting pin 26 to quickly complete the connection with different height connection points. This greatly simplifies the operation process, reduces the preparation time, and improves the work efficiency. In addition, during the movement of the equipment, the automatic cable 4 management function reduces the need for manual intervention, further improving the construction efficiency.

[0069] As an option, all the second limiting holes 2211 are equally spaced along the sliding direction of the first adapter arm 221.

[0070] Specifically, all the second limiting holes 2211 are equally spaced along the sliding direction of the first adapter arm 221, so that the operator can adjust them at a fixed step according to the specific height requirements of different types of heavy equipment connection points. This not only provides precise height adjustment, but also ensures consistency and predictability of each adjustment, improving the accuracy and reliability of the connection.

[0071] Referring to Figures 4-6As shown, as an option, the first adapter arm 221 is provided with a traction ring 2212 at one end of the connecting piece 23, and the connecting piece 23 and the traction ring 2212 are provided with a first connecting pin 2213, so that the connecting piece 23 can rotate around the first connecting pin 2213.

[0072] Specifically, the traction ring 2212 is designed to facilitate connection with vehicles such as trucks and cars. This allows the power distribution vehicle not only to be towed by heavy equipment, but also to be transported by more common trucks or cars, enabling rapid movement and relocation. This design greatly expands the application scenarios of the power distribution vehicle, enabling it to function in various working environments.

[0073] The connecting piece 23 is used to connect with heavy equipment such as excavators and pile drivers. This special connecting piece 23 ensures stable connection with specific models of heavy equipment, improving the reliability and safety of the connection.

[0074] By passing the connecting piece 23 and the traction ring 2212 through the first connecting pin 2213, the connecting piece 23 can be easily disassembled. This design allows operators to quickly switch connection methods according to actual needs, whether connecting heavy equipment using the connecting piece 23 or connecting trucks or cars using the traction ring 2212, enabling quick and easy operation. This not only reduces preparation time, but also improves work efficiency.

[0075] Since the traction ring 2212 and the connecting piece 23 can rotate around the first connecting pin 2213, when the heavy equipment is connected to the first adapter arm 221 through the connecting piece 23, a simple turn of the heavy equipment can enable the connecting piece 23 and the traction ring 2212 to transition more smoothly through their rotational relationship, thereby improving the stability of the vehicle frame during movement.

[0076] Referring to Figures 4-6 As shown, as an option, the second adapter arm 222 includes a sliding pipe 25, a first fork arm 2222, and a second fork arm 2223. The sliding pipe 25 is provided with a cavity that passes through the sliding pipe 25, forming a sliding groove 251. The second vehicle frame 2 has a first rotating connecting piece 27 and a second rotating connecting piece 28 on both sides facing the direction of the second adapter arm 222. One end of the first fork arm 2222 is fixedly connected to the side wall of the sliding pipe 25, and the other end is rotatably connected to the first rotating connecting piece 27. The second fork arm 2223 is arranged on the opposite side of the sliding pipe 25 connected to the first fork arm 2222, and is fixedly connected to the sliding pipe 25. The other end is rotatably connected to the second rotating connecting piece 28.

[0077] Specifically, the first fork arm 2222 is rotationally connected with the first rotation connecting piece 27. The first rotation connecting piece 27 can be rotationally connected with the first fork arm 2222 through a rotation shaft, or can be rotationally connected with the first fork arm 2222 through other structures, which is not limited here. Similarly, the second fork arm 2223 is rotationally connected with the second rotation connecting piece 28. The second rotation connecting piece 28 can be rotationally connected with the second fork arm 2223 through a rotation shaft, or can be rotationally connected with the second fork arm 2223 through other structures, which is not limited here. The first fork arm 2222 is rotationally connected with the first rotation connecting piece 27, and the second fork arm 2223 is rotationally connected with the second rotation connecting piece 28, thereby forming two rotation connecting points. The two rotation connecting points are respectively arranged on the two sides of the second frame 2, so that the movement of the adapter arm 22 at different heights and angles is more stable, and the overall stability is improved. That is, the arrangement of the two rotation connecting points makes the stress more uniform, reduces the structural deformation or damage caused by excessive stress of a single point, thereby prolonging the service life of the frame.

[0078] Referring to Figures 4-6 As shown in the figure, as an option, the second adapter arm 222 further includes a pull rod 2224. One end of the pull rod 2224 is fixedly connected to the first fork arm 2222 near the first rotation connecting piece 27, and the other end is fixedly connected to the second fork arm 2223 near the second rotation connecting piece 28.

[0079] Specifically, the addition of the pull rod 2224 further enhances the structural stability of the adapter arm 22. The pull rod 2224 is fixedly connected to the first fork arm 2222 and the second fork arm 2223 at both ends, forming a stable triangular structure, effectively reducing the shaking and deformation of the adapter arm 22 during movement, and ensuring the reliability of the connection.

[0080] Referring to Figures 4-6 Further, the first fork arm 2222 and the second fork arm 2223 are symmetrically arranged on both sides of the sliding pipe 25 with the sliding direction of the first adapter arm 221 as the axis of symmetry.

[0081] Specifically, the first fork arm 2222 and the second fork arm 2223 are symmetrically arranged on both sides of the sliding pipe 25 with the sliding direction of the first adapter arm 221 as the axis of symmetry. This symmetrical design makes the movement of the adapter arm 22 at different heights and angles more balanced and stable. The symmetrical structure distribution ensures the uniformity of the stress, reduces the structural deformation or damage caused by excessive stress on one side, thereby improving the overall stability.

[0082] Referring to Figures 4-6As shown, as optional, the second adapter arm 222 further comprises a first diagonal brace 2225 and a second diagonal brace 2226, one end of the first diagonal brace 2225 is fixedly connected with the middle part of the first fork arm 2222, the other end is fixedly connected with the middle part of the pull rod 2224, one end of the second diagonal brace 2226 is fixedly connected with the middle part of the second fork arm 2223, the other end is fixedly connected with the middle part of the pull rod 2224.

[0083] Referring to Figures 4-6 As shown, in particular, the addition of the first diagonal brace 2225 and the second diagonal brace 2226 forms multiple support points, making the structure of the adapter arm 22 more stable. The connection points of these diagonal braces with the first fork arm 2222, the second fork arm 2223 and the pull rod 2224 form multiple triangular structures, effectively dispersing the stress, reducing local stress concentration and improving overall stability.

[0084] Referring to Figures 4-6 As shown, further, the first diagonal brace 2225 and the second diagonal brace 2226 are symmetrically arranged on both sides of the sliding tube 25 with the sliding direction of the first adapter arm 221 as the axis of symmetry.

[0085] In particular, the first diagonal brace 2225 and the second diagonal brace 2226 are symmetrically arranged on both sides of the sliding tube 25 with the sliding direction of the first adapter arm 221 as the axis of symmetry. This symmetrical design makes the movement of the adapter arm 22 at different heights and angles more balanced and stable, ensuring the uniformity of the stress, reducing the structural deformation or damage caused by excessive unilateral stress, and thus improving the overall stability.

[0086] Referring to Figures 1-3As shown, in some embodiments, the cable support 13 comprises 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. The first side plate 130 and the second side plate 131 are oppositely arranged. The two ends of the first roller 132 are rotatably mounted to the first side plate 130 and the second side plate 131 respectively, so that the first roller 132 can rotate around its own axis. The two ends of the second roller 133 are rotatably mounted to the first side plate 130 and the second side plate 131 respectively, 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 to the side of the first side plate 130 facing the second side plate 131, and is arranged in a vertical direction, so that the third roller 134 can rotate around its own axis. The fourth roller 135 is rotatably mounted to the 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. The first roller 132 and the second roller 133 have a gap therebetween, and the first side plate 130, the first roller 132, the second side plate 131 and the second roller 133 form a cable passage 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.

[0087] Specifically, the cable support 13 is composed of the first side plate 130 and the second side plate 131. The first side plate 130 and the second side plate 131 are oppositely arranged and have a gap therebetween, so as to mount the rollers therebetween and provide a certain range for the deflection of the cable 4. The two ends of the first roller 132 and the second roller 133 are rotatably mounted to the first side plate 130 and the second side plate 131 respectively, so that the two rollers can rotate around their own axes. The first roller 132 and the second roller 133 are arranged in parallel and have a gap therebetween, which is used for the cable 4 to pass through. This 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 retraction, thereby reducing the risk of jamming during the movement of the cable 4 and reducing the wear of the insulating layer of the cable 4. The third roller 134 is mounted to the side of the first side plate 130 facing the second side plate 131, and the fourth roller 135 is mounted to the side of the second side plate 131 facing the first side plate 130. Both of them are arranged in a vertical direction. This structure can adapt to the change of the angle of the cable 4 relative to the support, 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.

[0088] Referring to Figures 1-3 As shown in the drawings, in some embodiments, the cable support 13 further comprises a fifth roller 136, one end of which 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.

[0089] Specifically, the fifth roller 136 is arranged on the side of the third roller 134 away from the first roller 132. Since the cable support 13 is usually installed on the top of the distribution vehicle, the cable 4 generally does not encounter obstacles when it rotates upward, but when it rotates downward, it may be limited by other parts of the distribution vehicle (such as the vehicle body structure, the distribution cabinet, etc.). By arranging the fifth roller 136 on the side away from the third roller 134, when the cable 4 rotates downward relative to the cable support 13, the cable 4 can change direction after contacting the fifth roller 136, which allows the cable 4 to smoothly pass through the fifth roller 136 and then adjust its direction, thereby avoiding interference with the components of the distribution vehicle itself.

[0090] And the fifth roller 136 can rotate freely around its own axis, which ensures smooth rolling of the cable 4 even if the cable 4 exerts pressure or changes angle during the change of direction, greatly reducing the probability of the cable 4 being stuck, and by providing a rotating contact surface for the cable 4, reducing the wear on the insulation layer of the cable 4, protecting the integrity and service life of the cable 4.

[0091] Referring to Figures 1-3 As shown in the drawings, as an option, the cable support 13 further comprises a sixth roller 137 and a seventh roller 138, the sixth roller 137 is rotatably assembled 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 assembled 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.

[0092] Specifically, in some extreme conditions, there is a situation that the cable 4 at the back of the cable support 13 contacts the first side plate 130 or the second side plate 131, the sixth roller 137 is rotatably assembled on the first side plate 130, and 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 assembled on the second side plate 131, and 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 it changes angle, reducing the risk of the cable 4 being stuck or tangled.

[0093] As optional, in order to improve the fitting effect of the cable support 13, the cable support 13 further comprises an eighth roller 139, one end of which is rotatably assembled to the first side plate 130, and the other end is rotatably assembled to 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.

[0094] Referring to Figures 7-11 As shown in the drawings, in some embodiments, the first frame 1 is provided with a first stop piece 15 on the side facing the second frame 2, and the second frame 2 is provided with two second stop pieces 24 on the side facing the first frame 1, and the two second stop pieces 24 are located on the movement track of the first stop piece 15.

[0095] Specifically, the first stop piece 15 is installed on the first frame 1 and rotates with the first frame 1, and the first stop piece 15 is located on the side of the first frame 1 facing the second frame 2, i.e. the opposite side of the first frame 1 and the second frame 2. Two second stop pieces 24 are respectively installed on the side of the second frame 2 facing the first frame 1, and the two second stop pieces 24 are located on the movement track of the first stop piece 15. Therefore, no matter whether the first stop piece 15 rotates clockwise or counterclockwise with the first frame 1, it will abut against one of the second stop pieces 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, and preventing the first frame 1 from rotating excessively, thereby avoiding the problem of entanglement of the cable 4.

[0096] Referring to Figures 7-10 As shown in the drawings, further, the two second stop pieces 24 are symmetrically arranged on both sides of the first stop piece 15 with the line connecting the first stop piece 15 to the rotation axis of the first frame 1 as the axis of symmetry.

[0097] Specifically, since the two second stop pieces 24 are symmetrically arranged, when the first frame 1 rotates in any direction, the first stop piece 15 will first contact one of the second stop pieces 24 and stop further rotation. This symmetrical arrangement ensures that the construction personnel can relatively accurately judge the rotation range of the first frame 1 when placing the rotating frame, so as to place the rotating frame in a position with sufficient rotation space in advance.

[0098] Referring to Figures 7-10 As optional, with the rotation axis of the first frame 1 as the center, the angle of the central angle formed by the line connecting the first stop piece 15 to the rotation axis and the line connecting any second stop piece 24 to the rotation axis is ninety degrees.

[0099] 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 whole system is relatively stable, that is, the center of gravity is biased to the position of the cable reel 12 with larger self-weight, in this case, even if the ground is slightly uneven, the power distribution vehicle can still maintain good balance. Once the rotation angle exceeds this range, the position of the cable reel 12 on the first frame 1 is displaced relative to the second frame 2, and if the construction personnel cannot take this into account in advance, the power distribution vehicle may roll over.

[0100] Referring to Figures 7-10 As shown in the figure, as an option, the first frame 1 and the second frame 2 can be connected by a rotating part 5, which can be a rotary bearing or a simple rotating shaft structure, which is not limited here, as long as it can make the first frame 1 rotate relative to the second frame 2.

[0101] Referring to Figure 11 As shown in the figure, as an option, the first frame 1 is provided with a first hook 16 and a second hook 17 at the end of the side where the cable reel 12 is arranged, and the first hook 16 and the second hook 17 have a gap therebetween.

[0102] Specifically, the first hook 16 and the second hook 17 can provide a winding structure for the external cable that supplies power to the power distribution vehicle, and the operator can simply wind the redundant external cable on the first hook 16 and the second hook 17, thereby effectively arranging the external cable, which can significantly reduce the dragging and stepping of the external cable on the construction site, thereby reducing the risk of damage to the external cable due to external force.

[0103] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above-mentioned embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, which are also considered within the protection scope of the utility model.
