Description

Technical Field

[0001] This utility model relates to the field of engineering 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-duty equipment and effectively manage cables. These vehicles can automatically retract and extend cables, ensuring they maintain appropriate tension and do not touch the ground, thus significantly reducing the risk of cable damage. However, most power distribution vehicle designs currently on the market are limited to chassis structures, especially the adapter arms, that are only compatible with specific models or types of heavy-duty equipment. This severely restricts the flexibility and economic efficiency of power distribution vehicles. Therefore, developing a power distribution vehicle chassis system that can flexibly adapt to various heavy-duty equipment is crucial to meet the needs of a wider range of applications while improving construction efficiency and safety. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art, the present invention provides a power distribution vehicle frame and a power distribution vehicle, which can provide a power distribution vehicle frame that can be flexibly adapted to a variety of different heavy industrial equipment to meet the needs of a wider range of application scenarios.

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

[0007] A power distribution vehicle frame, comprising:

[0008] A frame body, wherein wheels for balancing the frame body are connected to the frame body;

[0009] An adapter arm is provided, one end of which is rotatably connected to the frame body so that the adapter arm can rotate upward or downward relative to the height of the frame body. The other end of the adapter arm is provided with a connector for the frame body to be connected to an external power device through the connector of the adapter arm.

[0010] By adopting the above solution, the structural positions for connecting the power distribution vehicle to different models of heavy industrial equipment (such as excavators and pile drivers) may vary in height. Traditional fixed connection methods often only accommodate connection points of specific heights, limiting the application range of the power distribution vehicle. However, with an adjustable, vertically rotating adapter arm, it can flexibly connect to connectors of various heights, thus greatly expanding its support capability for different models of heavy industrial equipment. In other words, the same power distribution vehicle can serve multiple types of heavy industrial equipment, reducing the need to replace the power distribution vehicle when changing equipment, and improving equipment utilization and economic efficiency.

[0011] In addition, during actual construction, as the heavy equipment moves, the relative height between it and the power distribution vehicle may change. The adapter arm can rotate up and down relative to the frame body, which can improve the stability of the power distribution vehicle in this state.

[0012] Furthermore, the adapter arm includes a first adapter arm and a second adapter arm. One end of the second adapter arm is provided with a sliding groove, and the other end is rotatably connected to the frame body. One end of the first adapter arm is slidably disposed in the sliding groove, and the other end is provided with a connector.

[0013] By adopting the above solution, the first adapter arm can extend or shorten relative to the chute, allowing the power distribution vehicle to adapt to the height differences of connection points on different types of heavy industrial equipment. Whether it's a small excavator or a large piling machine, as long as the height of the connection point is within a certain range, a stable connection can be achieved by adjusting the position of the first adapter arm, thereby greatly improving the power distribution vehicle's support capability for various types of heavy industrial equipment.

[0014] The construction site has uneven terrain. When heavy equipment moves on this complex ground, its relative height to the ground constantly changes. By adjusting the sliding of the first adapter arm within the groove, the extension of the first adapter arm can be ensured, thereby increasing the overall length of the adapter arm. This allows the second adapter arm to rotate upwards at a smaller angle relative to the frame body to accommodate greater height differences, thus maintaining the overall stability of the power distribution vehicle.

[0015] Furthermore, it also includes an adjusting limiting structure, which includes a limiting pin, a first limiting hole, and a second limiting hole. The first limiting hole is located on the second adapter arm and extends through the slide groove. There are multiple second limiting holes, and all of the second limiting holes are located on the side of the first adapter arm facing the first limiting hole, so that when the limiting pin passes through the first limiting hole and one of the second limiting holes at the same time, it restricts the relative sliding of the first adapter arm and the second adapter arm.

[0016] By adopting the above solution, operators only need to adjust the position of the first adapter arm, locate the appropriate second limiting hole, and secure it with a limiting pin to quickly complete the connection with points at different heights. This method greatly simplifies the operation process, reduces preparation time, and improves work efficiency. Furthermore, during equipment movement, the automated cable management function reduces the need for manual intervention, further enhancing construction efficiency.

[0017] Furthermore, all the second limiting holes are equally spaced along the sliding direction of the first adapter arm.

[0018] By adopting the above scheme, all the second limiting holes are equally spaced along the sliding direction of the first adapter arm, allowing operators to adjust the height in fixed steps according to the specific height requirements of the connection points for different models of heavy industrial equipment. This not only provides precise height adjustment but also ensures consistency and predictability in each adjustment, improving the accuracy and reliability of the connection.

[0019] Furthermore, the first adapter arm has a traction ring at one end of the connector, and the connector and the traction ring are connected by a first connecting pin, so that the connector can rotate around the first connecting pin.

[0020] By adopting the above solution, the traction ring is specifically designed for easy connection with trucks, cars, and other vehicles. This allows the power distribution vehicle to be towed not only by heavy industrial equipment but also by more common trucks or cars, enabling rapid movement and transfer. This design greatly expands the application scenarios of the power distribution vehicle, allowing it to function in a variety of working environments.

[0021] The connectors are used to connect with heavy industrial equipment such as excavators and pile drivers. These specialized connectors ensure stable connection with specific models of heavy industrial equipment, improving the reliability and safety of the connection.

[0022] The connector can be easily disassembled by passing the first connecting pin through the connector and the towing ring. This design allows operators to quickly switch connection methods according to actual needs, whether using the connector to connect heavy equipment or the towing ring to connect a truck or car, enabling quick and easy operation. This not only reduces preparation time but also improves work efficiency.

[0023] Since both the traction ring and the connecting piece can rotate around the first connecting pin, when the heavy equipment is connected to the first transition arm through the connecting piece, the connecting piece and the traction ring can also achieve a smoother transition when the heavy equipment makes a simple turn, thereby improving the stability of the frame during movement.

[0024] Furthermore, the connector is L-shaped, and the lower end of the connector is rotatably connected to the traction ring through the first connecting pin. The upper end of the connector is provided with a second connecting pin, which is used to connect to an external power device.

[0025] By adopting the above solution, the L-shaped connector design not only provides structural stability and strength, but also adapts to different models and brands of heavy industrial equipment through its shape flexibility, improving overall applicability. The design of the second connecting pin allows the connector to be quickly connected and disconnected from external power equipment. This quick-disconnect function allows operators to quickly switch connection methods according to actual needs, whether using a tow ring to connect to a truck or car, or using the connector to connect to heavy industrial equipment, enabling quick and easy operation.

[0026] Furthermore, the second adapter arm includes a slide tube, a first fork arm, and a second fork arm. The slide tube has a cavity that extends through it, forming the slide groove. The frame body has a first rotating connector and a second rotating connector on both sides facing the second adapter arm. One end of the first fork arm is fixedly connected to the side wall of the slide tube, and the other end is rotatably connected to the first rotating connector. The second fork arm is located on the side of the slide tube opposite to the first fork arm and is fixedly connected to the slide tube. The other end is rotatably connected to the second rotating connector.

[0027] By adopting the above scheme, two rotating connection points are formed by rotating the first fork arm to the first rotating connector and the second fork arm to the second rotating connector. These two rotating connection points are located on both sides of the frame body, making the movement of the adapter arm more stable at different heights and angles, thus improving overall stability. In other words, the two rotating connection points result in more even force distribution, reducing structural deformation or damage caused by excessive force at a single point, thereby extending the service life of the frame.

[0028] Furthermore, the second adapter arm also includes a pull rod, one end of which is fixedly connected to the side of the first fork arm near the first rotating connector, and the other end is fixedly connected to the side of the second fork arm near the second rotating connector.

[0029] By adopting the above solution, the addition of the connecting rod further enhances the structural stability of the adapter arm. The connecting rod is fixedly connected to the first and second forks at both ends, forming a stable triangular structure. This effectively reduces the swaying and deformation of the adapter arm during movement, ensuring the reliability of the connection.

[0030] Furthermore, the first fork arm and the second fork arm are symmetrically arranged on both sides of the slide tube with the sliding direction of the first adapter arm as the axis of symmetry.

[0031] By adopting the above scheme, the first fork arm and the second fork arm are symmetrically arranged on both sides of the slide tube with the sliding direction of the first adapter arm as the axis of symmetry. This symmetrical design makes the movement of the adapter arm more balanced and stable at different heights and angles. The symmetrical structural distribution ensures the uniformity of force distribution, reduces structural deformation or damage caused by excessive force on one side, and thus improves the overall stability.

[0032] Furthermore, the second adapter arm also includes a first diagonal brace and a second diagonal brace. One end of the first diagonal brace is fixedly connected to the middle of the first fork arm, and the other end is fixedly connected to the middle of the pull rod. One end of the second diagonal brace is fixedly connected to the middle of the second fork arm, and the other end is fixedly connected to the middle of the pull rod.

[0033] By adopting the above scheme, the addition of the first and second diagonal braces creates multiple support points, making the structure of the adapter arm more stable. The connection points of these diagonal braces with the first fork arm, the second fork arm, and the tie rod form multiple triangular structures, effectively distributing the force, reducing local stress concentration, and improving overall stability.

[0034] Furthermore, the first diagonal brace and the second diagonal brace are symmetrically arranged on both sides of the slide tube with the sliding direction of the first adapter arm as the axis of symmetry.

[0035] By adopting the above scheme, the first and second diagonal braces are symmetrically arranged on both sides of the slide tube with the sliding direction of the first adapter arm as the axis of symmetry. This symmetrical design makes the movement of the adapter arm more balanced and stable at different heights and angles, ensuring the uniformity of force distribution, reducing structural deformation or damage caused by excessive force on one side, and thus improving the overall stability.

[0036] A power distribution vehicle, comprising the aforementioned power distribution vehicle frame.

[0037] In summary, the power distribution vehicle frame and power distribution vehicle provided by this utility model have the following technical effects:

[0038] 1. Different models of heavy industrial equipment (such as excavators and pile drivers) may have different structural positions for connecting to the power distribution vehicle. Traditional fixed connection methods often only accommodate connection points of specific heights, limiting the application range of the power distribution vehicle. However, with an adjustable, vertically rotating adapter arm, it can flexibly connect to connectors of various heights, greatly expanding its support capability for different models of heavy industrial equipment. In other words, the same power distribution vehicle can serve multiple types of heavy industrial equipment, reducing the need to replace the power distribution vehicle when changing equipment, and improving equipment utilization and economic efficiency.

[0039] 2. During actual construction, as the heavy equipment moves, the relative height between it and the power distribution vehicle may change. The adapter arm can rotate up and down relative to the frame body, which can improve the stability of the power distribution vehicle in this state. Attached Figure Description

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.

[0049] 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.

[0050] See Figures 1-5 This utility model discloses a power distribution vehicle frame, including a frame body 1 and an adapter arm 2. The frame body 1 is connected to wheels 11 for balancing the frame body 1. One end of the adapter arm 2 is rotatably connected to the frame body 1 so that the adapter arm 2 can rotate upward or downward relative to the height direction of the frame body 1. The other end of the adapter arm 2 is provided with a connector 23 for connecting the frame body 1 to external power equipment through the connector 23 of the adapter arm 2.

[0051] Specifically, the frame body 1 is connected to wheels 11 for balancing the frame body 1. These wheels 11 can be located on both sides of the frame body 1 where it connects to the adapter arm 2. Multiple pairs of wheels 11 can be used to improve the stability of the frame body 1. One end of the adapter arm 2 is rotatably connected to the frame body 1, allowing it to rotate upwards or downwards relative to the height of the frame body 1. The other end of the adapter arm 2 has a connector 23 for connecting the frame body 1 to an external power device. The rotatable connection between the adapter arm 2 and the frame body 1 can be achieved by having a rotating shaft pass through both the adapter arm 2 and the frame body 1, allowing the adapter arm 2 to rotate around the rotating shaft. Of course, other rotatable connection structures can also be used between the adapter arm 2 and the frame body 1, as long as they enable the rotatable connection. The external power device can be heavy industrial equipment such as excavators or pile drivers, or common power equipment such as trucks or automobiles; no limitation is made here.

[0052] See Figure 1 and Figure 2 As shown, in some embodiments, the adapter arm 2 includes a first adapter arm 21 and a second adapter arm 22. One end of the second adapter arm 22 is provided with a slide groove 241, and the other end is rotatably connected to the frame body 1. One end of the first adapter arm 21 is slidably disposed in the slide groove 241, and the other end is provided with a connector 23.

[0053] Specifically, the second adapter arm 22 has a groove 241 at one end and is rotatably connected to the frame body 1 at the other end. One end of the first adapter arm 21 is slidably disposed within the groove 241, allowing the first adapter arm 21 to slide along the groove 241. Since the first adapter arm 21 can extend or shorten relative to the groove 241, the power distribution vehicle can adapt to the height differences of connection points on different types of heavy industrial equipment. Whether it is a small excavator or a large piling machine, as long as the height of its connection point is within a certain range, a stable connection can be achieved by adjusting the position of the first adapter arm 21, thereby greatly improving the power distribution vehicle's support capability for various types of heavy industrial equipment.

[0054] The construction site has uneven terrain. When heavy equipment moves on this complex ground, its relative height to the ground constantly changes. By sliding the first adapter arm 21 within the slide groove 241, the extension of the first adapter arm 21 can be ensured to lengthen the overall length of the adapter arm 2. This allows the second adapter arm 22 to rotate upwards relative to the frame body 1 at a smaller angle to accommodate greater height differences, thereby maintaining the overall stability of the power distribution vehicle.

[0055] See Figure 1 and Figure 2As shown, in some embodiments, the adapter arm 2 further includes an adjustment limiting structure, which includes a limiting pin 25, a first limiting hole 221, and a second limiting hole 211. The first limiting hole 221 is located on the second adapter arm 22 and passes through the slide groove 241. There are multiple second limiting holes 211, and all the second limiting holes 211 are located on the side of the first adapter arm 21 facing the first limiting hole 221, so that when the limiting pin 25 passes through the first limiting hole 221 and one of the second limiting holes 211 at the same time, it restricts the relative sliding of the first adapter arm 21 and the second adapter arm 22.

[0056] Specifically, operators only need to adjust the position of the first adapter arm 21, locate the appropriate second limiting hole 211, and secure it with the limiting pin 25 to quickly complete the connection with points at different heights. This method greatly simplifies the operation process, reduces preparation time, and improves work efficiency. Furthermore, during equipment movement, the automated cable management function reduces the need for manual intervention, further enhancing construction efficiency.

[0057] Furthermore, all the second limiting holes 211 are equally spaced along the sliding direction of the first adapter arm 21.

[0058] Specifically, all the second limiting holes 211 are equally spaced along the sliding direction of the first adapter arm 21, allowing operators to adjust the height in fixed steps according to the specific height requirements of the connection points for different models of heavy industrial equipment. This not only provides precise height adjustment but also ensures consistency and predictability in each adjustment, improving the accuracy and reliability of the connection.

[0059] See Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the first adapter arm 21 is provided with a traction ring 212 at one end of the connector 23, and the connector 23 and the traction ring 212 are provided with a first connecting pin 213 so that the connector 23 can rotate around the first connecting pin 213.

[0060] Specifically, the towing ring 212 is designed for easy connection with trucks, cars, and other vehicles. This allows the power distribution vehicle to be towed not only by heavy industrial equipment but also by more common trucks or cars, enabling rapid movement and transfer. This design greatly expands the application scenarios of the power distribution vehicle, allowing it to function in a variety of working environments.

[0061] Connector 23 is used for connection with heavy industrial equipment such as excavators and pile drivers. This specialized connector 23 ensures stable connection with specific models of heavy industrial equipment, improving the reliability and safety of the connection.

[0062] The connector 23 can be easily disassembled by passing the first connecting pin 213 through the connector 23 and the towing ring 212. This design allows operators to quickly switch connection methods according to actual needs, whether using the connector 23 to connect heavy equipment or using the towing ring 212 to connect a truck or car, enabling quick and easy operation. This not only reduces preparation time but also improves work efficiency.

[0063] Since both the traction ring 212 and the connector 23 can rotate around the first connecting pin 213, when the heavy equipment is connected to the first transition arm 21 through the connector 23, the connector 23 and the traction ring 212 can also achieve a smoother transition when the heavy equipment makes a simple turn, thereby improving the stability of the frame during movement.

[0064] See Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the connector 23 is L-shaped, and the lower end of the connector 23 and the traction ring 212 are connected by a first connecting pin 213 to form a rotatable connection. The upper end of the connector 23 is provided with a second connecting pin 214, which is used to connect with an external power device.

[0065] Specifically, the design of the L-shaped connector 23 not only provides structural stability and strength, but also, through its shape flexibility, adapts to different models and brands of heavy industrial equipment, improving overall applicability. The design of the second connecting pin 214 allows the connector 23 to be quickly connected and disconnected from external power equipment. This quick-disconnect function allows operators to quickly switch connection methods according to actual needs, whether using the towing ring 212 to connect to a truck or car, or using the connector 23 to connect to heavy industrial equipment, enabling quick and easy operation.

[0066] See Figure 2 As shown, in some embodiments, the second adapter arm 22 includes a slide tube 24, a first fork arm 222, and a second fork arm 223. The slide tube 24 has a cavity that runs through it, forming a slide groove 241. The frame body 1 has a first rotating connector 12 and a second rotating connector 13 on both sides facing the second adapter arm 22. One end of the first fork arm 222 is fixedly connected to the side wall of the slide tube 24, and the other end is rotatably connected to the first rotating connector 12. The second fork arm 223 is located on the side of the slide tube 24 opposite to the first fork arm 222 and is fixedly connected to the slide tube 24. The other end is rotatably connected to the second rotating connector 13.

[0067] Specifically, the first fork arm 222 is rotatably connected to the first rotating connector 12. The first rotating connector 12 can be connected via a rotating shaft passing through it, or it can be connected via other structures; this is not limited here. Similarly, the second fork arm 223 is rotatably connected to the second rotating connector 13. The second rotating connector 13 can be connected via a rotating shaft passing through it, or it can be connected via other structures; this is not limited here. The rotatable connections of the first fork arm 222 and the first rotating connector 12, and the second fork arm 223 and the second rotating connector 13, form two rotating connection points. These two rotating connection points are located on both sides of the frame body 1, making the movement of the adapter arm 2 more stable at different heights and angles, thus improving overall stability. In other words, the two rotating connection points result in more even force distribution, reducing structural deformation or damage caused by excessive force at a single point, thereby extending the service life of the frame.

[0068] See Figure 2 As shown, in some embodiments, the second adapter arm 22 further includes a pull rod 224, one end of which is fixedly connected to the side of the first fork arm 222 near the first rotating connector 12, and the other end is fixedly connected to the side of the second fork arm 223 near the second rotating connector 13.

[0069] Specifically, the addition of the connecting rod 224 further enhances the structural stability of the adapter arm 2. The two ends of the connecting rod 224 are fixedly connected to the first fork arm 222 and the second fork arm 223, respectively, forming a stable triangular structure, which effectively reduces the swaying and deformation of the adapter arm 2 during movement and ensures the reliability of the connection.

[0070] See Figure 2 As shown, the first fork arm 222 and the second fork arm 223 are symmetrically arranged on both sides of the slide tube 24 with the sliding direction of the first adapter arm 21 as the axis of symmetry.

[0071] Specifically, the first fork arm 222 and the second fork arm 223 are symmetrically arranged on both sides of the slide tube 24 with the sliding direction of the first adapter arm 21 as the axis of symmetry. This symmetrical design makes the movement of the adapter arm 2 more balanced and stable at different heights and angles. The symmetrical structural distribution ensures the uniformity of force distribution, reduces structural deformation or damage caused by excessive force on one side, and thus improves the overall stability.

[0072] See Figure 2As shown, in some embodiments, the second adapter arm 22 further includes a first diagonal brace 225 and a second diagonal brace 226. One end of the first diagonal brace 225 is fixedly connected to the middle of the first fork arm 222, and the other end is fixedly connected to the middle of the pull rod 224. One end of the second diagonal brace 226 is fixedly connected to the middle of the second fork arm 223, and the other end is fixedly connected to the middle of the pull rod 224.

[0073] Specifically, the addition of the first diagonal brace 225 and the second diagonal brace 226 forms multiple support points, making the structure of the adapter arm 2 more stable. The connection points of these diagonal braces with the first fork arm 222, the second fork arm 223 and the tie rod 224 form multiple triangular structures, which effectively disperse the force, reduce local stress concentration, and improve the overall stability.

[0074] See Figure 2 As shown, the first diagonal brace 225 and the second diagonal brace 226 are symmetrically arranged on both sides of the slide tube 24 with the sliding direction of the first adapter arm 21 as the axis of symmetry.
