Description

Technical Field

[0001] This application relates to the field of power distribution line operation technology, and in particular to an aerial work device. Background Technology

[0002] Construction, inspection, and maintenance of power distribution lines, especially live-line work involving height operations, typically require the use of insulated boom lifts to raise personnel and equipment to designated heights on utility poles. The core function of these vehicles is to provide a stable and reliable high-altitude working platform; their stability and maneuverability are crucial for ensuring operational safety and efficiency. Ideally, such vehicles should be able to flexibly reach complex terrain at power line sites and provide a solid support foundation for the lifting mechanism upon arrival.

[0003] Currently, most common insulated bucket trucks use large truck chassis, which are bulky and have poor maneuverability on narrow or unpaved roads, making it difficult to park close to work sites in fields, mountains, and other remote locations. To address this mobility issue, existing technologies have developed solutions such as spider trucks with tracked chassis, which improve off-road capabilities. However, these vehicles are slow and still rely on other transport vehicles for long-distance transfers, unable to independently complete the entire journey from the base to remote work sites, increasing the complexity and time cost of operations. Therefore, existing aerial work platforms struggle to achieve a good balance between vehicle miniaturization, maneuverability, and independent driving capability, failing to fully meet the complex needs of power line field operations. Summary of the Invention

[0004] In view of this, this application provides an aerial work device, the main purpose of which is to solve the technical problem that existing aerial work devices are unable to achieve a good balance between vehicle miniaturization, passability and independent driving capability, and cannot fully meet the complex needs of field operations on power distribution lines.

[0005] This application provides an aerial work device, including: The vehicle body includes a first part and a second part; The cargo bed is mounted on the vehicle body of the second part; The working component is partially located inside the truck bed and partially located on the vehicle body of the first part. A support assembly, which is connected to the vehicle body.

[0006] In one feasible implementation, the job component includes: A support arm, wherein the support arm is disposed inside the truck bed; A lifting arm, which is connected to the support arm.

[0007] In one feasible implementation, the job component further includes: A telescopic arm, which is connected to the lifting arm; The work bucket is connected to the telescopic arm and is mounted on the vehicle body of the first part.

[0009] In one feasible implementation, the job component further includes: A support frame, one end of which is located inside the truck bed and the other end is connected to the lifting arm.

[0010] In one feasible implementation, the device further includes: A ladder, one end of which is located inside the truck bed and the other end of which is located on the truck body, with the end of the ladder on the truck body leading to the working bucket.

[0011] In one feasible implementation, the support component includes: The first leg is connected to the first part of the vehicle body.

[0012] In one feasible implementation, the support component further includes: The second leg is connected to the second part of the vehicle body, and there is a preset angle between the second leg and the vehicle body.

[0013] In one feasible implementation, the device further includes: The wheels are multiple in number, some of which are connected to the first part of the vehicle body and some of which are connected to the second part of the vehicle body.

The aerial work platform provided by this application, by employing a small off-road vehicle body and combining a first outrigger and a second outrigger positioned in specific locations, significantly enhances the vehicle's off-road capability and long-distance independent travel capability on unpaved roads, enabling it to directly reach remote work sites. The unique outrigger layout, combined with the distribution of the work assembly on the vehicle body, ensures the stability of the vehicle's center of gravity during lifting operations, effectively preventing the risk of tipping over. Simultaneously, the compact vehicle design allows it to flexibly park directly under poles, and with the support arm, lifting arm, and telescopic arm, it can still achieve the height required for most power distribution line operations while reducing the overall size of the device, thus achieving a good balance between vehicle passability, operational stability, and space utilization efficiency.

[0020] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application 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 application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] In the specific operations of power line construction, inspection, and maintenance, the operation of insulated bucket trucks follows a standardized procedure. First, the vehicle needs to travel from the base to the work location near the target power pole. Upon arrival, the operator carefully adjusts the vehicle's position to be as close to the pole as possible, while allowing sufficient space for the outriggers to extend. Then, the vehicle is turned off and the hydraulic system is activated. The operator lowers and levels the outriggers sequentially, firmly supporting the entire vehicle on the ground to form a stable working platform. Next, the operator enters the work bucket at the rear of the vehicle and, using the control devices on the control panel, sequentially activates the support boom, lifting boom, and telescopic boom, guiding the work bucket to avoid surrounding obstacles, smoothly raising it, and precisely positioning it at the working height on the power pole. After the work is completed, the operator controls the boom system to retract in reverse order, lowering the work bucket to the storage position, retracting the outriggers, and finally, the vehicle leaves the site to proceed to the next work location or return to the base. This series of operations places high demands on the vehicle's positioning flexibility, the stability of the outrigger support, and the precision of the boom's movements.

[0024] See Figure 1The diagram shows a structural schematic of an aerial work device provided in an embodiment of this application, comprising: The vehicle body comprises a first part and a second part; The cargo bed is mounted on the second part of the vehicle body; The work assembly is partially located inside the truck bed and partially located on the first part of the truck body; Support components, which are connected to the vehicle body.

[0025] In the above embodiment, the first part of the vehicle body mainly houses the cab and front wheels, while the second part mainly supports the cargo bed and rear wheels. This partitioned layout physically integrates and separates the vehicle's power unit, control unit, and operational functional units. The operational components are purposefully distributed in the cargo bed and the front of the vehicle body; this distribution helps to balance the overall center of gravity of the vehicle body during operation. Support components are connected to the bottom frame of the vehicle body to provide a stable support foundation when the vehicle is stationary during operation.

[0026] The partitioned vehicle body layout allows this application to retain the basic driving function of the vehicle while reserving reasonable space for the arrangement of high-altitude operation functions. Distributing the working components prevents the weight from being concentrated in one part of the vehicle body, laying a structural foundation for stable operation under the miniaturized vehicle body.

[0027] Furthermore, the job components include: Support arm 1, which is located inside the truck bed; Lifting arm 2 is connected to support arm 1.

[0028] In the above embodiment, the base of the support arm 1 is fixedly installed on the bottom structure of the truck bed, providing it with solid root support. One end of the lifting arm 2 is connected to the top of the support arm 1 by a hinge, and this hinge point constitutes the core pivot for the boom system to perform pitching movements. As the main load-bearing structure, the support arm 1 is responsible for transmitting the load borne by the lifting arm 2 and its extension components to the vehicle body.

[0029] By setting up a support arm 1 and a lifting arm 2, the basic boom lifting structure of the working device is formed. The support arm 1 is fixed inside the truck bed, making full use of the space and structural strength at the rear of the vehicle body, providing a stable and reliable installation foundation for the entire working assembly. The hinged connection between the lifting arm 2 and the support arm 1 enables flexible luffing movement of the boom within a certain angle range.

[0030] Furthermore, the job components also include: Telescopic boom 3 is connected to lifting boom 2; The work bucket 4 is connected to the telescopic boom 3 and is mounted on the vehicle body of the first part.

[0031] In the above embodiment, the telescopic arm 3 is nested above the lifting arm 2 and can extend and retract along the axial direction of the lifting arm 2. The work bucket 4 is fixed to the distal end of the telescopic arm 3 by a connecting mechanism that allows the work bucket 4 to adjust its posture within a certain range. In the non-working state, the work bucket 4 is stored and placed on top of the first part of the vehicle body, thereby reducing the overall size of this application.

[0032] The addition of the telescopic boom 3 significantly expands the horizontal working radius of the work bucket 4, enabling it to reach farther work points without changing the boom length. When not in operation, the work bucket 4 is stored on top of the front of the vehicle body. This layout makes the structure of this application compact, reducing the overall height and length in transport mode and enhancing maneuverability. As the platform that ultimately carries the workers, the movable connection between the work bucket 4 and the telescopic boom 3 ensures flexibility and fine-tuning capability in the working position.

[0033] Furthermore, the job components also include: Hydraulic oil pipe 5 is located at the connection between lifting arm 2 and support arm 1; Hydraulic cylinder 6, one end of which is connected to support arm 1 and the other end is connected to lifting arm 2, and hydraulic oil pipe 5 is connected to hydraulic cylinder 6.

[0034] In the above embodiment, the cylinder end of the hydraulic cylinder 6 is hinged to the support arm 1 at an appropriate position via a pin, while its piston rod end is similarly hinged to the end of the lifting arm 2 near the telescopic arm 3 via a pin. The hydraulic oil pipe 5 is arranged near the hinge point between the lifting arm 2 and the support arm 1 to supply hydraulic oil to the hydraulic cylinder 6, driving the extension and retraction of the piston rod. The extension and retraction of the hydraulic cylinder 6 is directly converted into the rotational motion of the lifting arm 2 around its hinge point with the support arm 1, thereby realizing the lifting and lowering of the boom.

[0035] Using hydraulic cylinder 6 as the driving element provides powerful and stable lifting force, ensuring stable and reliable operation. The hydraulic drive facilitates precise control and speed adjustment. By hinged at both ends of hydraulic cylinder 6 to support arm 1 and lifting arm 2 respectively, a stable and reliable lever drive structure is formed, with a clear and efficient force transmission path. The rational arrangement of hydraulic oil pipes 5 ensures an effective supply of hydraulic power.

[0036] Furthermore, the job components also include: Support frame 7, one end of which is located inside the truck bed, and the other end is connected to the lifting arm 2.

[0037] In the above embodiment, one end of the support frame 7 is fixed to the inner front wall of the truck bed, and the other end is connected to the end of the lifting arm 2 near the telescopic arm 3 via a releasable locking mechanism or auxiliary hinge. When the boom system is in the retracted state, the support frame 7 plays the main role in fixing and supporting. During the boom extension process, the connection between the support frame 7 and the lifting arm 2 is released to accommodate the boom movement.

[0038] The support frame 7 provides crucial auxiliary support for the retracted boom 2 during vehicle movement and parking, preventing the boom from swaying or structural fatigue due to bumps or its own weight, thus improving the stability and safety of this application. This application extends the boom's retraction support point forward from a single root hinge point, effectively distributing the load and reducing the bending moment borne by the root of the support boom 1, which is beneficial for extending the structural lifespan.

[0039] Furthermore, the device also includes: Ladder 10, one end of which is located inside the truck bed and the other end is located on the truck body. The end of ladder 10 located on the truck body leads to the working bucket 4.

[0040] In the above embodiment, the bottom entrance of the ladder 10 is located inside the truck bed, and its ladder body extends upward along the side profile of the first part of the truck body, with its top exit pointing towards and close to the work bucket 4 in its retracted state. The steps and handrails of the ladder 10 are designed with anti-slip features to ensure the safety of personnel going up and down.

[0041] Ladder 10 provides operators with a safe and convenient passage, enabling them to smoothly enter the work bucket 4 located at the front of the vehicle from the ground via the truck bed area. This conforms to ergonomic principles and improves work preparation efficiency. Placing the entrance of ladder 10 inside the truck bed helps integrate equipment functions and maintains the neatness of the vehicle's external outline.

[0042] Furthermore, the supporting components include: The first leg 8 is connected to the first part of the vehicle body.

[0043] In the above embodiments, the first support leg 8 is preferably a vertical support leg, which is connected to the chassis beam of the first part of the vehicle body, i.e., the part including the cab, by a robust mounting bracket. The first support legs 8 are usually arranged in pairs on the left and right sides of the front of the vehicle body, and may contain a hydraulic or mechanical telescopic mechanism to realize the vertical lifting and lowering of the support leg.

[0044] The first leg 8 directly enhances the support rigidity and stability of the front of the vehicle during operation. Especially when the work basket 4 carries personnel and extends far forward, it effectively suppresses the tendency of the front of the vehicle to rise and prevents the vehicle from tilting forward. Its vertical support characteristic means that it requires less lateral space when deployed, making it particularly suitable for use in confined spaces.

[0045] Furthermore, the supporting components also include: The second support leg 9 is connected to the second part of the vehicle body, and there is a preset angle between the second support leg 9 and the vehicle body. Preferably, the second support leg 9 is an angled support leg, installed at the rear end of the second part of the vehicle body, i.e., the part carrying the cargo bed. The connection between the cylinder of the second support leg 9 and the vehicle chassis is such that, when extended, it forms a preset acute angle with the vehicle chassis plane, tilting towards the rear of the vehicle. This design ensures that when its support foot is fully extended, it is located at the rear lower part of the vehicle body profile.

[0046] The oblique arrangement of the second support leg 9, when deployed, generates a component force pointing downwards and forwards of the vehicle body. This component force effectively counteracts the backward overturning moment generated by the rearward rotation and extension of the lifting arm 2, greatly enhancing the anti-overturning capability of this application when operating in the rear area. Positioning the second support leg 9 at the very rear of the vehicle body maximizes the use of the lever arm principle and improves support efficiency.

[0047] In the above embodiments, Furthermore, the device also includes: The wheels are multiple in number, some connected to the first part of the vehicle body and some connected to the second part of the vehicle body.

[0048] In the above embodiments, the wheels typically include front wheels and rear wheels. The front wheels are mounted on the front axle of the first part of the vehicle body and are responsible for steering and partial drive. The rear wheels are mounted on the rear axle of the second part of the vehicle body and are mainly responsible for drive. The wheels are preferably off-road tires suitable for unpaved roads, and the vehicle's transmission system, suspension system, etc., are all designed with high passability in mind.

[0049] The use of a multi-wheeled off-road vehicle chassis endows this application with strong autonomous driving capabilities and off-road passability, enabling it to independently handle complex terrains such as fields and mountains, and to maneuver long distances to the work site, overcoming the limitations of traditional large bucket trucks or tracked spider trucks that rely on transportation. The compact body size results in a smaller turning radius, more flexible handling, and the ability to easily park at the optimal working position directly under the target utility pole.

[0050] Furthermore, the device also includes: The driver's cab is located inside the first part of the vehicle body.

[0051] In the above embodiment, the cab is integrated at the front of the first part of the vehicle body, and is equipped with a standard vehicle control interface such as a steering wheel, control system, instrument panel, and seat. It can also integrate a dedicated control panel for controlling operating components such as boom movement and outrigger movement, enabling centralized or time-sharing control of driving and operating functions.

[0052] Placing the cab at the front of the vehicle is a conventional and ergonomic layout, providing the driver with excellent forward visibility and ensuring driving safety. This layout naturally separates the driving area from the rear working area, clearly defining functional zones and avoiding mutual interference. This makes this application both a qualified off-road vehicle and a highly efficient aerial work platform.

[0053] This application provides a schematic diagram of the structure of an aerial work device, including: a vehicle body, which includes a first part and a second part; a cargo box, which is disposed on the vehicle body of the second part; a work component, which is partially disposed inside the cargo box and partially disposed on the vehicle body of the first part; and a support component, which is connected to the vehicle body.

[0054] The aerial work platform provided in this application significantly enhances the vehicle's off-road capability and long-distance independent travel capability on unpaved roads by adopting a small off-road vehicle body and combining a first and second outrigger set in specific positions, enabling it to directly reach remote work sites. The unique outrigger layout, combined with the distribution of the working components on the vehicle body, ensures the stability of the vehicle's center of gravity during lifting operations, effectively preventing the risk of tipping over. At the same time, the compact body design allows it to flexibly park directly under the pole, and with the support arm, lifting arm, and telescopic arm, it can still reach the height required for most power distribution line operations while reducing the overall size of the device, thus achieving a good balance between vehicle passability, operational stability, and space utilization efficiency.
