Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation safety protection and maintenance auxiliary equipment in the field of power engineering technology, specifically to an insulated platform applied to auxiliary pole operations. Background Technology

[0002] In power transmission systems, electrical equipment frequently malfunctions due to factors such as electrical aging, thermal aging, and mechanical fatigue caused by long-term operation, or due to external environmental corrosion leading to decreased insulation performance and mechanical structural damage. When such malfunctions occur, maintenance personnel must climb the towers of overhead transmission lines to inspect and maintain insulators, hardware, conductors, and other equipment. Because these high-altitude maintenance operations require prolonged work on towers several meters or even tens of meters above the ground, maintenance personnel not only face the safety risks associated with working at height but also expend significant physical energy to complete the various tasks. Furthermore, the installation location and specifications of hardware on the towers often exceed the normal operating range of the maintenance personnel's limbs, forcing them to frequently adjust their body posture and sometimes even require auxiliary tools to reach the target location, greatly increasing the difficulty and safety hazards of the work.

[0003] To address the challenges of working at heights, insulated platforms are widely used as auxiliary equipment in the power inspection field. By providing a stable working space, these platforms effectively reduce the physical strain on maintenance personnel and improve safety. However, existing insulated platforms still face several technical bottlenecks: First, the lifting and rotating mechanisms of traditional insulated platforms have limitations, making precise positioning and flexible adjustment difficult, and failing to meet the need for efficient maintenance of hardware beyond the human operating range; second, the overall structure is complex, bulky, and heavy, lacking convenient folding and storage design, resulting in low efficiency in equipment transportation and on-site deployment; third, the work process design is unreasonable, with a lack of effective coordination between functional modules, leading to cumbersome operation steps, difficulty in improving work efficiency, and inability to meet the timeliness requirements of power systems for rapid fault repair. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide an insulated platform for auxiliary pole operations. This solves the technical problems of existing insulated platforms in the field of high-altitude operation safety protection and maintenance auxiliary equipment in the field of power engineering technology, such as inconvenient lifting and rotation, large size and weight making them difficult to store and transport, and low operation efficiency. This improves the convenience and timeliness of high-altitude power maintenance.

The two active rotating bodies are fixedly connected by a rotating shaft. The two active rotating bodies are fixedly connected vertically by a connecting rod. Rotary limiting plates are rotatably connected to both ends of the rotating shaft. A limiting groove is formed on the inner side of the rotating limiting plate near the inner side of the driven rotating body. A limiting strip is provided on the inner ring of the driven rotating body. The limiting strip is built into the rotating limiting plate. The driven rotating body is formed by two semi-circular driven rotating bodies fixedly spliced ​​together by a splicing plate.

[0026] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This embodiment provides an insulated platform for auxiliary pole operation, including a lifting mechanism 1, a rotating mechanism 2, and a platform assembly 3.

[0027] In this embodiment, the lifting mechanism 1, the rotating mechanism 2, and the platform assembly 3 are all made of aluminum.

[0028] Furthermore, the rotating mechanism 1 includes an active rotating body 11, a driven rotating body 12, an auxiliary rotating body 13, and a rotation drive source 14.

[0029] Preferably, the active rotating body 11, the driven rotating body 12, and the auxiliary rotating body 13 are all selected as gears, that is, the rotating mechanism 1 is driven by gear transmission. The application of gear transmission to this insulation platform has the following advantages: 1. Compact structure and small footprint: Under the same transmission ratio and power, the structure of gear transmission is more compact than belt transmission and chain transmission, making the insulation platform easy to transport, install, and disassemble; 2. Reliable operation and long service life: Gear materials are usually made of high-strength steel or alloys, and undergo heat treatment processes such as quenching and carburizing, resulting in high surface hardness and good wear resistance, enabling them to withstand large loads and improving the service life of the insulation platform; 3. Easy to standardize and mass-produce: The tooth profile, module, pressure angle, and other parameters of the gears have been standardized internationally / nationally (such as ISO and GB), facilitating specialized production and interchangeable maintenance, thus reducing the cost of the insulation platform.

[0030] Furthermore, the output end of the rotary drive source 14 is driven to the active rotary body 11, the active rotary body 11 is driven to the driven rotary body 12, the two active rotary bodies 11 are fixedly connected by a rotating shaft 15, and the two active rotary bodies 11 are fixedly connected vertically by a connecting rod 16.

[0031] Furthermore, the rotation drive source 14 is selected as a servo motor.

[0032] Furthermore, when the platform component 3 needs to rotate, the rotation drive source 14 is energized to drive the active rotating body 11 to rotate. Since the active rotating body 11 and the driven rotating body 12 are engaged by spur teeth, the active rotating body 11 rotates around the driven rotating body 12, thereby driving the platform component 3 to rotate around the pole 4.

[0033] Rotary limiting plates 17 are rotatably connected to both ends of the rotating shaft 15. A limiting groove 17A is opened on the inner side of the rotating limiting plate 17 near the inner side of the driven rotating body 12. A limiting strip 12A is provided on the inner ring of the driven rotating body 12. The limiting strip 12A is built into the rotating limiting plate 17. The driven rotating body 12 is fixedly spliced ​​by two semi-circular driven rotating bodies 121 through splicing plate 122.

[0034] Furthermore, the upper rotating limiting plate 17 is placed at the upper end of the upper driven rotating body 12, and the lower rotating limiting plate 17 is placed at the lower end of the lower driven rotating body 12. The two rotating limiting plates 17, the limiting groove 17A, and the limiting strip 12A are used to vertically limit the two driven rotating bodies 12 to prevent the driven rotating bodies 12 from detaching from the driving rotating body 11 and affecting the stability of the insulating platform.

[0035] Furthermore, the auxiliary rotating body 13 is rotatably connected to the lower rotating limiting plate 17, and simultaneously engages with the driven rotating body 12, serving to assist rotation and improve the stability of the insulating platform. When the driving rotating body 11 rotates around the driven rotating body 12, the auxiliary rotating body 13 simultaneously rotates around the driven rotating body 12.

[0036] Furthermore, the rotating mechanism 1 also includes a pole locking mechanism 18. Each of the driven rotating bodies 12 is provided with the pole locking mechanism 18 along the diametrical direction. When the operator lifts the rotating mechanism 1 to a certain height, the pole locking mechanism 18 mechanically abuts against and locks the pole through the output shaft, so that the rotating mechanism 1 remains stationary relative to the pole.

[0037] In this embodiment, the rotating mechanism can achieve a 260° rotation of the platform component.

[0038] Furthermore, the lifting mechanism 2 includes a lifting column 21, a lifting drive source 22, a lifting slider 23, a rope winding drum 24, and a lifting rope 25.

[0039] Furthermore, the two lifting columns 21 are fixedly connected to the end of the rotating limiting plate 17 away from the driven rotating body 11, the lifting slider 23 is slidably connected to the lifting columns 21, and the sliding wheel 221 provided in the lifting slider 22 is tightly fitted and slidably connected to the sliding surface of the lifting column 21.

[0040] Furthermore, a pulley bracket 26 is fixedly connected to the upper end of the lifting column 21, and a pulley 261 is rotatably connected inside the pulley bracket 26. A lifting drive source 22 is fixedly connected to the lower end of the lifting column 21, and the output end of the lifting drive source 22 is driven by the rope drum 24 through a reducer 27.

[0041] Furthermore, the lifting drive source 22 is a servo motor.

[0042] Furthermore, the reducer 27 is selected as a worm gear reducer. The application of a worm gear reducer to this insulated platform has the following advantages: 1. Large transmission ratio and outstanding reduction capacity: The transmission ratio of a worm gear drive can typically reach 10:1 to 80:1 (or even higher). When the insulated platform needs to be lifted slowly, the worm gear reducer can directly convert the high speed of the lifting drive source 22 into the low speed of the rope winding drum 24, avoiding uncontrolled platform lifting due to excessive speed; 2. Compact structure and space saving: Under the same transmission ratio, the volume of a worm gear reducer is smaller than that of a multi-stage gear reducer, significantly saving installation space; 3. Self-locking characteristics ensure the safety of platform component lifting: The worm gear drive has reverse self-locking properties (depending on the worm lead angle and friction coefficient). When the worm is the driving element, the worm can rotate normally; however, when the worm drives the worm in the reverse direction due to the weight of the load (such as a sudden power outage during the lifting of the platform component), the transmission will automatically lock to prevent the platform component 3 from falling.

[0043] Furthermore, the upper end of the rope winding drum 24 is provided with a rope arrangement assembly 28, which includes a timing belt 281, a rope arrangement rotating shaft 282, and a rope arrangement block 283.

[0044] Furthermore, the rope winding drum 24 is driven to the rope-laying rotating shaft 282 via a synchronous belt 281 and a synchronous pulley 284. The rope-laying block 283 has a mounting hole and a rope-laying hole 283A. The rope-laying block 283 is threadedly connected to the rope-laying rotating shaft 282 via the mounting hole.

[0045] Furthermore, when the lifting rope 25 passes through the rope arrangement hole 283A, the lifting drive source 22 drives the rope winding drum 24 to rotate. Under the action of the synchronous belt 281, the rope arrangement rotating shaft 282 is driven to rotate, and the rope arrangement block 283 is driven to move back and forth along the rope arrangement rotating shaft 282. This forces the lifting rope 25 to be arranged layer by layer and turn by turn on the surface of the rope winding drum 24, avoiding problems such as rope tangling and cross-entanglement caused by uneven tension of the lifting rope 25 or changes in the rotation speed of the rope winding drum 24.

[0046] Furthermore, the lifting column 21 is provided in two sets, and each set of the lifting column 21 is slidably connected to two sets of lifting sliders 22. One end of the four lifting sliders 22 is fixedly connected to the four corners of the lifting moving plate 29, and a pull rod 221 is provided between the two lifting sliders 22 at the upper end.

[0047] Furthermore, one end of the lifting rope 25 passes through the rope hole 283A and is fixedly connected to the rope winding drum 24, and the other end of the lifting rope 25 is wound around the pulley 261 and connected to the pull rod 221 through the hanging ring 262.

[0048] Furthermore, the platform component 3 includes a movable support rod 31, a fence 32, a platform body 33, and a diagonal support rod 34.

[0049] Furthermore, one end of the platform body 33 is detachably and fixedly connected to the upper lifting slider 22 via a ball joint pin, which facilitates disassembly and assembly.

[0050] Furthermore, the lower lifting slider 22 is fixedly connected to one end of the movable support rod 31, and the other end of the movable support rod 31 is fixedly connected to the other end of the platform body 33. A railing 32 is fixedly connected to the upper end of the platform body 33. The railing 32 closest to the utility pole 4 is 0.4 meters away from the pole. The railing 32 is designed to reduce the risk of falls for workers while ensuring that workers are within a 0.4-meter insulation distance working range. A tool bag hook 321 is fixedly installed at the upper end of the railing 32 for workers to hang tool bags. A safety warning strip is affixed to the upper end of the platform body to warn workers of the safe working area and improve work safety.

[0051] Furthermore, one end of the diagonal brace is fixedly connected to one side of the platform body 33, and the other end of the diagonal brace 34 is fixedly connected to the upper end of the fence 32, wherein the diagonal brace 34 is arranged at an angle to the platform body 33 to strengthen the fence 32.

[0052] Furthermore, the platform body 33 is made of epoxy resin fiberglass insulation material, which is a non-conductive material, further improving the safety of workers.

[0053] Furthermore, the lifting column 21 is provided with lifting limit sensing units 222 on the upper and lower sections of one side, the driven rotating body 12 is provided with rotation limit sensing units 121 on the inner ring, and a double hook safety belt suspension frame 5 is provided above the platform assembly 3. The double hook safety belt suspension frame 5 is fixed to the pole 4.

[0054] Furthermore, when the platform component 3 descends to contact the lifting limit sensor unit 222, the descent action automatically stops, thus providing limit protection for the lifting of the platform component 3.

[0055] Furthermore, when the platform component 3 rotates, triggering the rotation limit sensing unit 121, the rotational motion automatically stops, providing rotation limit protection for the platform component 3, thereby further improving the stability of the insulating platform operation.

[0056] Furthermore, the rotating mechanism 1 also includes an auxiliary rotating component 19, which includes an auxiliary rotating guide rod 191, an auxiliary rotating cylinder 192, and an auxiliary rotating wheel 193.

[0057] Furthermore, the auxiliary rotating cylinder 192 is fixed to the bottom end of the lifting column 21 by the auxiliary rotating bracket 194, and the auxiliary rotating guide rod 191 is built into the auxiliary rotating cylinder 192; an elastic element is provided between the auxiliary rotating guide rod 191 and the auxiliary rotating cylinder 192, and one end of the auxiliary rotating cylinder 192 is rotatably connected to the auxiliary rotating wheel 193, and the tread of the auxiliary rotating wheel 193 is in close contact with the wall of the pole 4.

[0058] Furthermore, when the platform assembly 3 rotates, the auxiliary rotating wheel 193 is in close contact with the wall of the pole 4 and rotates around it. The auxiliary rotating assembly 19 plays a supporting and assisting role. When the wall is uneven, the elastic element extends and retracts to make the tread of the auxiliary rotating wheel 193 in close contact with the wall of the pole 4.

[0059] Furthermore, the elastic element is selected as a spring.

[0060] In this embodiment, an electrical control cabinet 6 is also provided on one side of the lifting column 21. The electrical control cabinet 6 is equipped with an electrical control system and a lithium battery. The electrical control system controls the rotation and lifting of the platform component 3, and the lithium battery provides power to the insulated platform to ensure the stability of the rotation and lifting of the insulated platform.

[0061] Furthermore, when the insulated platform is not in use, it can be disassembled and placed in a packaging box with an EVA lining and casters at the bottom to facilitate storage and transportation of the equipment and extend its actual service life.
