Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary devices for live-line work, and in particular to an adjustable insulating platform for live-line work. Background Technology
[0002] Live-line work refers to maintenance, inspection, or installation work carried out while the power equipment is still energized. The purpose is to avoid production interruptions and economic losses caused by power outages. Live-line work requires the use of an insulated platform because such a platform can effectively isolate the current, ensure the safety of workers, and prevent the risk of electric shock. The insulated platform is made of materials with high-strength insulation properties, has sufficient stability and flexibility, can adapt to different working environments, and ensure the safety of workers when performing high-risk operations.
[0003] The working principle of an insulated platform is based on the use of high-strength insulating materials. These materials can effectively isolate current and prevent current from being conducted to the worker's body through the platform, thereby avoiding electric shock accidents. When a worker stands on the insulated platform to perform live work, the platform provides him with a safe environment isolated from the power source, ensuring that current will not be conducted through the worker and guaranteeing safety during the operation. Insulated platforms usually have excellent electrical insulation performance and mechanical strength, and can withstand the load and environmental changes during the operation.
[0004] In the existing technology, some insulated platforms still have some shortcomings, specifically a lack of flexibility and adaptability. Such insulated platforms usually use a fixed design, which makes it impossible to adjust the position or height of the platform according to different work requirements, thus limiting its application in variable working environments. Secondly, such insulated platforms usually require a relatively complex installation process, and once installed, they are difficult to move or adjust, which is not suitable for scenarios that require frequent changes of work location. Therefore, an adjustable insulated platform for live-line work is proposed to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Reference Figures 1 to 3This utility model provides an embodiment of an adjustable insulated platform for live-line work, comprising a platform 1. Platform 1 serves as the work surface and provides support for workers. It is typically constructed of robust insulating material (e.g., steel coated with rubber) to ensure safety during live-line work. Two platform vertical supports 19 are detachably connected to the left side of platform 1. These supports are detachably connected to the platform 1 via screws and nuts, providing vertical support. A limiting shaft 18 is fixedly connected to the adjacent side of the two platform vertical supports 19. The limiting shaft 18 is a transverse component connecting the two platform vertical supports 19. It is a round shaft that is smaller at both ends and larger in the middle, limiting the movement range of platform 1 to ensure that platform 1 does not sway during worker work and movement. An adjustment mechanism is detachably connected to the bottom of the limiting shaft 18 for adjustment. The height of platform 1 is adjustable to meet different work requirements. Fixed frames 20 are slidably connected to both sides of the adjustment mechanism. Fixed frames 20 are the outer shell of the adjustment mechanism and the angle adjustment mechanism, providing protection for the angle adjustment mechanism and ensuring that the angle adjustment mechanism is not affected by external forces during operation, so as to maintain the stability of platform 1 during the adjustment process. An angle adjustment mechanism is fixedly connected to the top of the adjustment mechanism. The angle adjustment mechanism is used to adjust the angle of platform 1 to meet different work requirements. A guardrail 3 is fixedly connected to the top of platform 1 to prevent workers from falling on platform 1 due to accidents, thereby improving the safety of platform 1. Two platform supports 2 are detachably connected to the bottom of platform 1. The platform vertical support 19 is located on the left side of platform 1 and is detachably connected to platform 1 by screws and nuts to provide vertical support. The other ends of the two platform supports 2 are detachably connected to the opposite side of the platform vertical support 19.
[0027] The adjustment mechanism includes an adjustment connecting block 8, which is slidably connected to one side of the fixed frame 20. In conjunction with the rotation of the screw 7, it converts rotational force into linear motion for fine adjustment of the platform 1. The adjustment connecting block 8 is slidably connected to one side of the fixed frame 20. The screw 7 is rotatably connected inside the adjustment connecting block 8. The screw 7 is driven by a working gear 6, thereby moving the adjustment connecting block 8. The screw 7's thread, due to its special characteristic of linear rotational conversion, ensures a smooth and precise adjustment process. The working gear 6 is rotatably connected to the outside of the screw 7. An adjustment protective shell 21 is rotatably connected to the top of the screw 7. A transmission gear 5 is rotatably connected inside the adjustment protective shell 21. A drive wheel 4 is fixedly connected inside the transmission gear 5. The transmission gear 5 transmits power to the working wheel 4 through the drive of the drive wheel 4. The gear 6 drives the screw 7 to rotate, thus adjusting the height or angle of the platform 1. Two connecting hooks 17 are fixedly connected to the right side of the adjusting connecting block 8. The limiting shaft 18 is connected to the adjusting mechanism through these two connecting hooks 17. The connecting hooks 17 play a fixing role, ensuring a stable connection between the limiting shaft 18 and the adjusting mechanism. The limiting shaft 18 is detachably connected inside the two connecting hooks 17. The fixed block 9 has a bearing 24 rotatably connected inside. The bearing 24 ensures that the rotating worm gear 14 will not affect the fixed block 9 during rotation, thus ensuring stability during the adjustment process. The bearing 24 has a worm gear 14 fixedly connected inside. The fixed frame 20 has a sliding groove inside, and the adjusting connecting block 8 is slidably connected inside the sliding groove. The screw 7 has threads on the outside.
[0028] Reference Figure 4 , Figure 5The angle adjustment mechanism includes a second drive wheel 16, which drives a worm gear 14 via a drive worm 15, thereby adjusting the angle of platform 1. The worm 15 is fixedly connected internally to the second drive wheel 16, and the worm gear 14 is rotatably connected internally to the adjustment protective shell 21. The worm gear 14 and worm 15 are key transmission components in the adjustment mechanism. The worm gear 14 and worm 15 mesh with each other, and the rotation of the worm gear 14 is driven by the worm 15, thus transmitting rotational force and adjusting the angle of platform 1. A connecting rod 13 is fixedly connected externally to the worm gear 14, and the worm gear 14 is coupled to the worm 15. Three fixing components are fixedly connected externally to the worm gear 14, including a fixing block 9. The fixing block 9 is a part fixed in the adjustment mechanism and has an internal bearing 24 to ensure that the rotating worm gear 14 does not affect the fixing block 9 during rotation, thus ensuring stability during adjustment. The fixing block 9 is fixedly connected to the outside of the fixing frame 20, and a rotating block 10 is rotatably connected internally to the fixing block 9. A rotating ring 11 is fixedly connected to the left side of the rotating block 10. The rotating block 10 is connected to the support frame's safe area through the rotating ring 11. The multi-segment arc design of the rotating ring 11 allows it to connect with the support frame's installation area. The fixing screws 12 on the outside of the rotating ring 11 are used to secure the connection and prevent loosening during angle adjustment. The rotating ring 11 is a circular block composed of multiple arc segments. The fixing screws 12 are detachably connected to the outside of the rotating ring 11. A support block 22 is fixedly connected to the side of the fixed block 9 that is close to the platform vertical support 19. An auxiliary pulley 23 is rotatably connected inside the support block 22. The support block 22 cooperates with the platform vertical support 19 through the auxiliary pulley 23. The auxiliary pulley 23 reduces friction. During the adjustment of the platform 1, the auxiliary pulley 23 helps the platform 1 move smoothly along the platform vertical support 19. The auxiliary pulley 23 corresponds to the platform vertical support 19. Screws are provided on both sides of the fixed block 9, which fix the fixed block 9 to both sides of the fixed frame 20.
[0029] Working principle: The insulating platform includes a platform, a platform support 2, and a platform vertical support 19. The platform provides a working and support platform for workers, while the platform supports 2 located on both sides of the platform provide support for the platform, and the platform vertical support 19 provides vertical support for the platform. At the same time, the liquid level limiting shaft 18 provides the installation direction. For the connection between the platform 1 and the adjustment mechanism, it is only necessary to hang the limiting shaft 18 on the connecting hook 17. The limiting shaft 18 is a round shaft with small ends and a large center, which limits the possibility of accidents caused by the insulating platform during the process of hanging on the connecting hook 17, thereby improving safety. Meanwhile, the support block 22 and auxiliary pulley 23 fixed at the bottom of the fixing block 9 provide support for the insulating platform in another direction. The auxiliary pulley 23 is a wheel-shaped round shaft, thereby improving the stability of the insulating platform during the adjustment process.
[0030] When height adjustment is required, the drive wheel 4 is rotated, and the transmission gear 5 drives the working gear 6, causing the screw 7 to rotate. The externally threaded connection allows the adjusting connecting block 8 to move linearly during rotation. The sliding groove inside the platform vertical support 19 limits the range and direction of movement of the adjusting connecting block 8. Then, the connecting hook 17 fixed to the left side of the adjusting connecting block 8 engages with the limiting shaft 18, completing the vertical adjustment of the platform 1. This allows the insulating platform 1 to adjust its height according to different operational needs, ensuring that operators can work in the optimal position and reducing fatigue and injury risks caused by physical discomfort or improper posture. The drive wheel 16 is then rotated to drive the worm gear 15, which in turn drives the connecting rod 13 through a coupling connection, thereby driving the worm wheel 14 to rotate. The worm wheel 14 drives the three externally connected rotating blocks 10 to rotate, thus completing the angle adjustment of the insulating platform. This improves the flexibility and comfort during operation, ensuring that operators can maintain the optimal working posture at different working angles. During this process, the bearing 24 inside the fixed block 9 prevents the fixed block 9 from being affected by the rotation of the worm wheel 14.
