Technical Field

[0001] This invention relates to the field of live-line working platform technology for power distribution networks, specifically to a live-line working bucket truck and its working method for power distribution networks. Background Technology

[0002] In the field of power system operation and maintenance, live-line work on distribution networks is a key operational method to ensure a continuous and stable power supply. Its core is to complete line maintenance, fault diagnosis, and equipment replacement without interrupting power to the distribution network, minimizing the impact of power outages on production and daily life. The live-line work boom truck, as the core equipment for this operation, provides operators with a high-altitude working platform through its body load-bearing structure, extended robotic arm, and end-load support components. It is the fundamental guarantee for the safe and efficient implementation of live-line work on distribution networks.

[0003] Currently, the end-load structure of existing live-line working bucket trucks typically adopts a fixed-size load-bearing box design. This load-bearing box is connected to the end of the bucket truck's robotic arm via a fixed bracket. The interior is pre-designed to accommodate 1-2 operators and provides a limited area for tool placement. To ensure structural stability and overall vehicle balance during robotic arm extension, the length, width, and other dimensions of the load-bearing box are fixed at the factory and do not have a flexible expansion structure. During operation, operators must complete line operations within the fixed space, while maintenance tools are placed in the pre-designed small tool slots or platforms inside the load-bearing box.

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides a live-line working bucket truck and its operating method, comprising a vehicle body 1. The upper surface of the vehicle body 1 is rotatably connected to a control compartment 2. A support assembly 3 is installed inside the vehicle body 1, with a tire 4 rotatably connected to one end of the support assembly 3. An extension assembly 1 rotatably connects inside the vehicle body 1, with a support frame 6 installed at one end of the extension assembly 1 5. An extension assembly 2 rotatably connects inside the vehicle body 1, with a bucket assembly 8 installed at one end of the extension assembly 2 7.

[0037] Specifically, the control compartment 2 is used by workers to drive the support assembly 3 to unfold and fix it, operate the extension assembly 1 5 to adjust the working position, and control the extension assembly 2 7 and the bucket assembly 8 to clear debris. The support assembly 3 is driven by the control compartment 2 to enhance its grip on the ground, fixing the vehicle body 1 in the working position and preventing the vehicle body from shaking or shifting due to external forces generated by the movement of the extension assembly or personnel operations. The extension assembly 1 5 is used to send the end-connected load-bearing assembly 1 56 to the height required for live-line work on the power distribution network, providing reliable position support for operators to perform live-line inspection and maintenance on the load-bearing assembly. The extension assembly 2 7 and the bucket assembly 8 are used to clear weeds and rocks under the power distribution network before live-line work, such as by extending the bucket assembly 8 to the target area to be cleared, thus clearing obstacles in advance for live-line work.

[0038] Please see the appendix Figure 3 The bucket assembly 8 includes a second support block 81, which is fixedly connected to the outside of the second extension assembly 7. An electric push rod 82 is rotatably connected to the inside of the second support block 81. The output end of the electric push rod 82 is connected to a first rotating rod 83. A second rotating rod 84 is rotatably connected to the outside of the first rotating rod 83. The inside of the second rotating rod 84 is rotatably connected to the outside of the second support block 81. The inside of the second rotating rod 84 is rotatably connected to the bucket body 85. The inside of the bucket body 85 is rotatably connected to the outside of the second support block 81.

[0039] Specifically, when debris needs to be cleared, the opening and closing size of the bucket body 85 is adjusted by the extension and retraction of the electric push rod 3 82 to accommodate debris of different sizes, such as small stones and weeds. When the electric push rod 3 82 extends, it pushes the rotating rod 1 83 to rotate around the connection point, thereby driving the rotating rod 2 84 to rotate synchronously. When the electric push rod 3 82 retracts, it pulls the rotating rod 1 83 to rotate in the opposite direction, similarly driving the rotating rod 2 84 to move in the opposite direction. Before live-line work on the power grid, the bucket body 85 clears obstacles such as weeds and stones from the work area to prevent debris from affecting live-line operations or causing safety hazards due to debris contacting live lines.

[0040] Please see the appendix Figure 4 The extension component 5 includes a support column 51, the bottom end of which is fixedly connected to the inside of the vehicle body 1. A driver 52 is fixedly connected to the outside of the support column 51. A support seat 53 is rotatably connected to the upper surface of the support column 51. The driver 52 drives the support seat 53 to rotate. A robotic arm 54 is rotatably connected inside the support seat 53. A robotic arm 55 is rotatably connected to one end of the robotic arm 54. A load-bearing component 56 is rotatably connected to one end of the robotic arm 55.

[0041] Specifically, the driver 52 drives the support base 53 to rotate around the upper surface of the support column 51 by outputting torque, so as to realize the angle adjustment of the support base 53 and the subsequent robotic arm and the first load-bearing component 56 within a 360° range in the horizontal direction. The first load-bearing component 56 can cover a larger horizontal area around the work point without moving the vehicle body 1. The first robotic arm 54 and the second robotic arm 55 work together to deliver the first load-bearing component 56 to the live work point of the power distribution network at different heights, so as to meet the inspection and maintenance needs of the power distribution network at different heights. The first load-bearing component 56 provides a stable working space for the operator.

[0042] Please see the appendix Figure 5 The support assembly 3 includes a support block 31, which is installed inside the vehicle body 1. A rotating block 32 is fixedly connected to one end of the support block 31. An electric push rod 33 is rotatably connected inside the rotating block 32. A support rod 34 is rotatably connected inside the rotating block 32. The electric push rod 33 is rotatably connected to the inside of the support rod 34. A giant tooth 35 is connected to the output end of the electric push rod 33. One end of the giant tooth 35 is rotatably connected to the inside of the support rod 34.

[0043] Specifically, the electric push rod 33 drives the support rod 34 to rotate downward or upward around the rotating block 32, causing the giant tooth 35 to extend and fit against the ground. When the support rod 34 fits against the ground, the giant tooth 35 is embedded in the ground or stuck in the ground gap, preventing slippage between the support rod 34 and the ground, further improving the grip of the support component 3, and effectively preventing the vehicle body 1 from shifting due to external forces generated by the movement of the robotic arm or personnel.

[0044] Please see the appendix Figure 6 The first load-bearing component 56 includes a third robotic arm 561. An L-shaped block 562 is fixedly connected to the bottom end of the third robotic arm 561. An electric push rod 563 is rotatably connected inside the L-shaped block 562. An installation block 564 is rotatably connected to the output end of the electric push rod 563. The installation block 564 is rotatably connected to the outside of the L-shaped block 562. A fixing post 565 is fixedly connected to the outside of the installation block 564. A first load-bearing box 566 is fixedly connected to the outside of the fixing post 565.

[0045] Specifically, the electric push rod 563 pulls or pushes the mounting block 564 to rotate around the L-shaped block 562, thereby causing the fixed column 565 and the carrier box 566 to adjust their angles synchronously. The carrier box 566 can accommodate 1-2 operators and also houses working tools such as insulated wrenches, voltage detectors, and insulated gloves, providing a safe working space for the operators.

[0046] Please see the appendix Figures 7-8 The fixed column 565 is also fixedly connected to the outside of the bearing component 2 9. The bearing component 2 9 includes a bearing box 2 91. One end of the bearing box 2 91 is slidably connected to a sliding plate 1 92, and the other end of the bearing box 2 91 is slidably connected to a sliding plate 2 93. The lower surface of the bearing box 2 91 is fixedly connected to a base plate 95, and the inside of the bearing box 2 91 is fixedly connected to a support plate 94. The outside of the sliding plate 1 92 and the sliding plate 2 93 are both slidably connected to the outside of the support plate 94. The outside of the support plate 94 is fixedly connected to a stop bar 96, and the lower surface of the stop bar 96 is fixedly connected to the upper surface of the base plate 95. The outside of the sliding plate 1 92 is fixedly connected to a step block 97. The inside of the stop bar 96 is rotatably connected to a rotating column 98. The outside of the rotating column 98 is fixedly connected to a support platform 99, and the outside of the step block 97 is set outside the support platform 99.

[0047] Specifically, sliding plate 1 92 and sliding plate 2 93 expand the overall bearing area of ​​bearing component 2 9 by sliding outward along support plate 94, solving the problem of insufficient initial bearing space, providing operators with more room to move and improving work convenience. Step block 97 presses support platform 99 with its own slope, triggering support platform 99 to rotate and unfold, realizing the extension and retraction of sliding plate and unfolding of support platform 99. The placement space can be automatically expanded without additional operation, simplifying the operation process.

[0048] A method for operating a bucket truck for live-line working on power distribution networks includes the following steps:

[0049] S1. Vehicle positioning: The vehicle body 1 is driven to the live-line work site via tires 4, and initially aligned with the work area;

[0050] S2. The body 1 is fixed. The support component 3 is activated through the control compartment 2. The electric push rod 33 extends and drives the support rod 34 to support the ground downward. The giant tooth 35 enhances the grip and stabilizes the body 1.

[0051] S3. Adjust the working position, operate the extension component 1 5, drive the support base 53 to rotate, and coordinate with the extension of the robotic arm 1 54 and the extension of the robotic arm 2 55 to send the load-bearing component 1 56 to the specified working height and position.

[0052] S4. Adjust the load-bearing state. Electric push rod 2 563 drives mounting block 564 to rotate, adjusting the angle of load box 1 566; push sliding plate 1 92 and sliding plate 2 93 to expand the load-bearing area, and step block 97 lifts support platform 99 to form a tool placement plane.

[0053] S5. Clean up debris as needed. Operate the extension component 2 7 to the debris area. The electric push rod 3 82 drives the rotating rod 1 83 and the rotating rod 2 84 to open and close the bucket body 85 to complete the cleaning.

[0054] S6. Operation reset, reverse operation to retract the bucket body 85 and extension component 2 7, reset the robotic arm and load-bearing component, and finally retract the support rod 34 and giant tooth 35.

[0055] Specifically, after the vehicle arrives at the live-line work site, the support assembly 3 is activated to fix the vehicle body. The electric push rod 33 is extended by the control compartment 2. The electric push rod 33 drives the support rod 34 to rotate around the rotating block 32 and support it to the ground. At the same time, it drives the giant tooth 35 to contact the ground to enhance the grip and prevent the vehicle body 1 from shaking and shifting during operation. Next, the operator controls the extension assembly 5 to adjust the working position through the control compartment 2. The driver 52 drives the support seat 53 to rotate horizontally. With the extension and folding of the robotic arm 54 and robotic arm 55, the end bearing assembly 56 is sent to the designated working height and position. Then, the positions of bearing assembly 56 and bearing assembly 9 are adjusted. The electric push rod 563 extends and retracts to drive the mounting block 564 to rotate to adjust the angle of the bearing box 566. Then, the operator pushes the sliding plate 92 and sliding plate 93 of the bearing box 91 to slide along the support plate 94 to expand the bearing area.

[0056] When sliding plate 1 92 and sliding plate 2 93 slide, sliding plate 1 92 will drive the step block 97 to slide. At this time, the sliding of step block 97 will squeeze the support platform 99, and the outside of the support platform 99 will slide along the slope of step block 97. When sliding plate 1 92 contacts the outside of the stop bar 96, the support platform 99 will be pushed to the upper surface of step block 97 by step block 97. At this time, the support platform 99 is in a flat state, which makes it convenient for workers to place their tools.

[0057] When debris needs to be cleared, extend the second extension component 7 to the target area, activate the third electric push rod 82 to extend and retract, and drive the bucket body 85 to open and close by rotating rod 1 83 and rotating rod 2 84 to complete the digging, transportation or leveling operation. Finally, after the operation is completed, reset in reverse order: first retract the third electric push rod 82 to close the bucket body 85, retract the second extension component 7, then retract the first robotic arm 54 and the second robotic arm 55 to reset the load-bearing component, and finally retract the first electric push rod 33 to retract the support rod 34 and the giant tooth 35 to complete the entire operation process.
