Description

Technical Field

[0001] This utility model relates to the field of power construction technology, and in particular to a mobile and portable transmission line laying and crossing frame sealing platform. Background Technology

[0002] With rapid economic development, power construction has flourished across the country, and an increasing number of power lines need to cross highways and high-speed railways. During the construction of transmission lines, when the laying section needs to cross a highway, it is often necessary to use a netted crossing frame at the highway crossing point.

[0003] Traditional methods of netting enclosures rely primarily on manual labor. One method requires two workers in a special "flying vehicle" to secure the netting ropes or poles. However, at the lowest point of the conductor, the safe distance between the workers and the object being crossed cannot be adequately guaranteed. Furthermore, each enclosure requires nearly an hour of continuous high-altitude work, resulting in significant physical exertion for the workers. The safety harnesses and safety pulleys for personnel are all attached to a single conductor, further complicating the safety process. Another method involves erecting scaffolding on both sides of the area to be crossed, with the netting installed between the scaffolding. This method is labor-intensive and time-consuming, requiring at least 20 people working together for three days to complete a single enclosure, wasting manpower and resources. Additionally, it may encounter issues such as land occupation during construction, delaying the project and making this method inefficient. Utility Model Content

The bottom inner wall of the integral steel frame has a notch, the insulating net is installed on the inner wall of the integral steel frame located in the notch, and the turning mechanism is fixedly connected to the bottom of the integral steel frame.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-3A portable transmission line laying and crossing frame sealing platform includes an integral steel frame 1, an insulating net 2, and a turning mechanism 3. The bottom inner wall of the integral steel frame 1 has a notch, the insulating net 2 is set on the inner wall of the integral steel frame 1 located in the notch, and the turning mechanism 3 is fixedly connected to the bottom of the integral steel frame 1. The integral steel frame 1 adopts a steel structure frame, and the outer edge of the integral steel frame 1 is welded with steel pipes. Multiple reinforcing ribs are welded at the gaps between multiple steel pipes on the integral steel frame 1.

[0018] The overall steel frame 1 is made of steel and is 15 meters long, 10 meters wide, and 5 meters high. The insulating net 2 is a large net woven from insulating material, which is 15 meters long and 10 meters wide. The size of the insulating net 2 is perfectly matched with the overall steel frame 1 and is hung on the inner wall of the recess of the overall steel frame 1.

[0019] The steering mechanism 3 has a steering bearing inside and is assembled at the connection between the integral steel frame 1 and the top of the crane boom.

[0020] The overall steel frame 1 is the core support structure of the platform. It adopts a steel frame design, with the outer edge welded with steel pipes. The reinforcing ribs welded at the gaps between the steel pipes can enhance the overall structural strength and ensure that the platform can withstand the tension of the conductor, the weight of the tools, and the workload of the personnel during the laying process. The overall steel frame 1 is set with a length of 15 meters, a width of 10 meters, and a height of 5 meters, which not only meets the protection range requirements of most transmission line crossing scenarios, but also takes into account portability. The notch opened on the inner wall at the bottom is used to install the insulating net 2, providing a carrier for the protective function.

[0021] The insulating net 2 is a key component for safety protection. It is woven from insulating material and its dimensions perfectly match the overall steel frame 1, hanging on the inner wall of the recess in the overall steel frame 1. During the construction of power transmission line laying, the conductor passes through the laying device above the platform. If the conductor accidentally breaks or falls, the insulating net 2 can directly support the conductor, preventing it from falling onto obstacles below. At the same time, the insulating material can prevent the high voltage of the power transmission line from being conducted to the lower area through the net, ensuring the electrical safety of the area below. The support beam 4 fixed at the bottom of the overall steel frame 1 is located below the insulating net 2 and can provide auxiliary support for the insulating net 2, preventing excessive sagging or damage when the insulating net bears heavy objects, thus improving the reliability of protection.

[0022] The steering mechanism 3 is the core component that enables the platform to be adjustable and its angle adjustable. It has a steering bearing inside and is assembled at the connection between the overall steel frame 1 and the top of the crane boom. The material is stainless steel to ensure corrosion resistance and structural stability. During construction, the overall steel frame 1 is lifted by the crane, and the steering bearing inside the steering mechanism 3 can be used to flexibly adjust the horizontal angle of the overall steel frame 1 so that the insulating net 2 can accurately cover the area that needs to be protected below. At the same time, the crane can move the platform as a whole to adapt to the changes in the position of the conductor during the laying construction, ensuring that the protection range always matches the laying path and achieving a dynamic protection effect of laying and protecting as needed.

[0023] During construction, the entire steel frame 1 is first lifted by a truck crane, and the platform angle is adjusted by the steering mechanism 3 so that the insulating net 2 covers the area below the obstacle. Then the power line laying operation begins, with the conductor passing through the platform. The insulating net 2 is always directly below the conductor to catch any conductors or tools that may fall.

[0024] To avoid excessive deformation of the insulation mesh 2, such as Figure 1-3 As shown, the steering mechanism 3 is made of stainless steel, and the bottom of the overall steel frame 1 is fixedly connected to a support beam 4, which is located below the insulating net 2.

[0025] Support beam 4 continuously provides support for insulating net 2, preventing excessive deformation of the net. After the line is laid, the platform is lifted away by a truck crane to complete the protection operation. The overall structure balances mobility and safety, adapting to the temporary protection needs of power transmission line laying and crossing construction, and its portable design facilitates transportation between different construction sites.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
