Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-altitude operations, and in particular relates to a multi-purpose intelligent high-altitude insulated operation platform for power distribution network maintenance. Background Technology
[0002] Pole-climbing operations involve workers directly climbing to the designated work position, allowing for convenient position adjustments and offering good accuracy and flexibility. However, due to the harsh working environment and complex influencing factors, especially with double-circuit vertically arranged overhead lines, maintenance and repair are difficult when only one side is out of power. Even with certain protective measures, safety cannot be adequately guaranteed, and the risk of electric shock or falls is high. Aerial work platforms, on the other hand, use mechanical lifting to transport workers to the work position while providing a safe working space, improving the safety and quality of the work process.
[0003] Currently, power emergency repair operations face complex environments and fault causes, with numerous hazards and uncontrollable factors. Manual pole climbing is labor-intensive and carries significant safety risks. Furthermore, manual pole climbing is difficult in rainy, snowy, or frosty weather. Traditional insulated bucket trucks used for work platforms are expensive to purchase, few in number, and difficult to deploy when maintenance tasks are heavy. Moreover, bucket trucks are difficult to operate in confined spaces, delaying maintenance time. Due to the complex and changeable environment of the power distribution network, the work projects are limited and have low adaptability, and manual pre-treatment of the work site is required. Utility Model Content
[0004] In view of this, the present invention aims to propose a multi-purpose intelligent high-altitude insulated working platform for power distribution network maintenance, in order to solve the problems of complex power emergency repair work environment and fault causes, many dangerous points and force majeure factors, high labor intensity and high safety risks of manual pole climbing, and difficulty in manual pole climbing in rainy, snowy and frost weather. The traditional working platform uses insulated bucket trucks, which are expensive to purchase, few in number, and difficult to deploy when maintenance tasks are heavy. In addition, the bucket trucks are difficult to operate in confined spaces, which delays maintenance time. Furthermore, the complex and changeable environment of the power distribution network affects the single operation items and low adaptability, and requires manual pre-treatment of the work site.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0008] Furthermore, the luffing mechanism includes a second hydraulic cylinder, a pulley system, a wire rope, a winch, and a telescopic ladder. The second hydraulic cylinders are symmetrically arranged around the centerline of the telescopic ladder. One side of each second hydraulic cylinder is fixed to the outside of the bottom ladder frame of the telescopic ladder by a pin, and the other side is fixed to the turntable by a pin. The telescopic ladder is divided into three telescopic sections, including a first telescopic section, a second telescopic section, and a third telescopic section. The winch is fixed to the bottom of the telescopic ladder, and the wire rope passes around the pulley system from the winch.
[0009] Furthermore, the pulley system includes a first fixed pulley, a second fixed pulley, a third fixed pulley, a fourth fixed pulley, and a fifth fixed pulley, with any one of the fixed pulleys fixed to its corresponding telescopic section by bolts; the first telescopic section has a first fixed pulley on its left side and a second fixed pulley on its right side, with the first fixed pulley located above the second fixed pulley; the second telescopic section has a third fixed pulley on its left side and a fourth fixed pulley on its right side, with the third fixed pulley located above the fourth fixed pulley; the third telescopic section has a fifth fixed pulley at its top, and the wire rope passes sequentially from the winch upwards around the first fixed pulley, the second fixed pulley, the third fixed pulley, the fourth fixed pulley, and the fifth fixed pulley.
[0010] Furthermore, the insulated work platform includes a standing platform, handrails, a pole-holding device, a first hydraulic cylinder, and a first level sensor. The standing platform is three-quarters circular in shape, with a groove in the middle and handrails on the periphery. The groove is flared to accommodate the utility pole. The pole-holding device is used to lock the utility pole and is connected to the standing platform by bolts. The first hydraulic cylinder is fixed to the standing platform by pins and is connected to the first level sensor. The pole-holding device is independently powered by a battery pack located below the standing platform.
[0011] Furthermore, the pole-holding device includes a pole-holding motor, a pole-holding rack, and a drive gear; the drive gear is mounted on a gear shaft, which is connected to the pole-holding motor, and the other end is connected to a gear shaft mounting base via a bearing; the gear shaft mounting base is fixed to the standing platform by bolts, and the pole-holding motor is fixed to the standing platform by bolts; the pole-holding rack meshes with the drive gear, and the pole-holding rack is semi-circular and slides within a groove on the standing platform.
[0012] Furthermore, a first limit switch and a second limit switch are provided at the groove opening of the standing platform. The first limit switch and the second limit switch are respectively fixed to the groove opening below the standing platform by bolts. The first limit switch is away from the pole motor, and the second limit switch is close to the pole motor.

[0015] Compared with existing technologies, the multi-purpose intelligent high-altitude insulated work platform for power distribution network maintenance described in this utility model has the following advantages:
[0016] (1) The system installed inside the tracked chassis of this utility model is relatively heavy, while the telescopic ladder and the insulated working platform on it are made of insulating material and are very light in weight. The weight of a single worker is far less than the weight of the tracked chassis itself. The folding outriggers have a large unfolding area, and the center of gravity of the entire system is always within the range of the four outrigger fulcrums, which can ensure that the vehicle will not overturn and protect the safety of the workers. The multi-purpose intelligent high-altitude insulated working platform combines a self-leveling tracked chassis and an insulated telescopic ladder. After being recycled, the overall size is small, which is convenient for transportation and adapts to various complex and narrow areas and various harsh road conditions.
[0017] (2) The telescopic ladder in this utility model uses a winch combined with a wire rope and pulley system to control the extension and shortening of the ladder frame. The turntable combined with the luffing mechanism allows the insulated ladder to rotate 360° and adjust the pitch angle of the insulated ladder to adapt to any position near the pole and align with the pole. When the pole is located in the middle of the bell mouth, the pole clamping device under the insulated platform will rotate and clamp, preventing the working platform from detaching from the pole and ensuring the safety of the workers. Both the working platform and the telescopic ladder are made of insulating material, and the pole clamping device is independently powered by the battery pack under the platform to ensure the overall insulation performance.

[0038] Specifically, in this embodiment, the insulated work platform 3 includes a standing platform 301, a handrail 302, a pole-holding device 303, a first hydraulic cylinder 304, and a first level sensor 305. The standing platform 301 is three-quarters circular in shape, with a groove in the middle and a handrail 304 on the periphery. The groove is flared and used to embed the utility pole 9. The pole-holding device 303 is used to lock the utility pole and is connected to the standing platform 301 by bolts. The first hydraulic cylinder 304 is fixed to the standing platform 301 by pins and is connected to the first level sensor 305. The pole-holding device 303 is independently powered by a battery pack under the standing platform 301.
[0039] Specifically, in this embodiment, the pole-holding device 303 includes a pole-holding motor 3034, a pole-holding rack 3031, and a drive gear. The drive gear is mounted on a gear shaft 3032, which is connected to the pole-holding motor 3034. The other end of the gear shaft is connected to a gear shaft mounting base 3033 via a bearing. The gear shaft mounting base 3033 is fixed to the standing platform 301 by bolts, and the pole-holding motor 3034 is fixed to the standing platform 301 by bolts.

[0040] Specifically, in this embodiment, a first limit switch 3035 and a second limit switch 3036 are provided at the groove opening of the standing platform 301. The first limit switch 3035 and the second limit switch 3036 are respectively fixed to the groove opening below the standing platform 301 by bolts.

The pole motor 3034 is connected to the first limit switch 3035 and the second limit switch 3036 respectively.
[0041] Specifically, in this embodiment, the telescopic ladder 203 and the insulated working platform 3 are made of lightweight insulating materials.
[0042] Specifically, in this embodiment, a power battery pack, a fuel generator, a hydraulic motor, a tracked bogie, and a hydraulic system are installed inside the tracked chassis 101. The tracked bogie drives the tracked chassis 101 to rotate in the horizontal plane. The power battery pack, the fuel generator, and the hydraulic motor are connected. The tracked bogie is driven by the hydraulic motor in the hydraulic system.
[0043] In this embodiment, a second level sensor is installed inside the tracked chassis to control the operation of the third hydraulic cylinders of the four folding outriggers. The third hydraulic cylinders act on the joints of the folding outriggers to control their deployment and retraction, while simultaneously adjusting the levelness of the tracked chassis. Outrigger support plates are installed at the bottom of the folding outriggers to increase the ground contact area and prevent them from sinking into the ground due to soft ground during operation, thus affecting the stability of the high-altitude insulated work platform. A turntable allows the telescopic ladder to rotate 360°, and a second hydraulic cylinder in the luffing mechanism controls the pitch angle of the telescopic ladder. The working height is controlled by the pitch and extension of the telescopic ladder. The telescopic ladder's movement is controlled by a combination of wire rope and pulley systems. A winch is installed on the bottom ladder frame of the telescopic ladder, which, in conjunction with the pulley system, pulls the wire rope to extend or retract the telescopic ladder. A first hydraulic cylinder inside the insulated work platform adjusts the angle of the insulated work platform and the telescopic ladder. A first level sensor is also installed inside the insulated work platform to control the extension and retraction of the first hydraulic cylinder below the insulated platform, ensuring that the platform where the operator stands is always level. The groove in the middle of the insulated work platform allows the center of the standing platform to be embedded into the pole 9, making it convenient for workers to complete their tasks from all directions around the pole 9. Moreover, the groove is designed in the shape of a flared mouth, which makes it easy to adjust the telescopic ladder to embed the pole into the insulated work platform.
[0044] A pole-clamping device is installed beneath the insulated work platform. This device, controlled by a small motor, rotates a gear to clamp the utility pole. The pole-clamping device opens when the insulated work platform is raised, and closes and locks the pole once it is centered within the platform. During operation, the insulated work platform remains locked, preventing it from detaching from the pole and enhancing worker safety. Handrails are provided on the platform for hanging tool bags and installing safety rope clips. After work is completed, the pole-clamping device reopens, and a rope and pulley system retracts the telescopic ladder. A luffing mechanism then lowers the ladder to its transport position.
[0045] The system installed within the tracked chassis is relatively heavy, while the telescopic ladder and the insulated work platform on top are made entirely of insulating materials (such as fiberglass), making the overall weight very light (around 200kg). Combined with the weight of a single worker, this is far less than the weight of the tracked chassis itself. The folding outriggers have a large unfolded area, and the entire system's center of gravity remains within the four outrigger fulcrums, ensuring the vehicle does not tip over and guaranteeing worker safety. The multi-purpose intelligent insulated aerial work platform combines a self-leveling tracked chassis with an insulated telescopic ladder. After retrieval, its compact size facilitates transport and adapts to various complex and confined areas and harsh road conditions.
[0046] The telescopic ladder uses a winch combined with a wire rope and pulley system to control the extension and retraction of the ladder frame. A turntable combined with a luffing mechanism allows the insulated ladder to rotate 360° and adjust its pitch angle, adapting to any position near the utility pole for alignment. Upon reaching the pole at the center of the flared end, the pole-clamping device beneath the insulated platform rotates and clamps, preventing the work platform from detaching from the pole and ensuring worker safety. Both the work platform and the telescopic ladder are made of insulated material, and the pole-clamping device is independently powered by a battery pack beneath the platform, ensuring overall insulation performance.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
