Description

Technical Field

[0001] The utility model specifically relates to the technical field of ladder protection, in particular to a ladder protection device for an electric tower. Background Art

[0002] When assembling an electric tower, a climbing frame needs to be installed inside the tower for the convenience of later maintenance. However, when the climbing frame is installed, protective devices must be installed on the position groups on both sides. The traditional climbing frame protective devices are welded through steel structures, and the gap between two adjacent connecting beams is large. When performing protection, it cannot effectively block the human body, which may cause people to fall from the gap between the two connecting beams.

[0003] Chinese patent application number CN201721470767.6 is a climbing frame protective mesh; it includes a protective net and a mesh frame, the mesh frame constitutes a quadrilateral structure, the protective net is fixedly provided in the mesh frame, and a plurality of reinforced oblique square tubes are obliquely fixed in the mesh frame, a plurality of connecting sleeves are vertically provided on the outer surfaces at both ends of the mesh frame, the connecting sleeves and the fixed sleeves on the climbing frame uprights are matched, and a limiting axis is fixedly passed through the connecting sleeves and the fixed sleeves at the same time, and an anti-bending baffle is also provided on the outer side of the mesh frame, and the anti-bending baffle is movably clamped on the climbing frame uprights.

[0004] The protective net in the above patent is installed in the mesh frame, and multiple mesh frames are connected by anti-bending baffles and limiting ribs arranged on both sides and both ends of the mesh frame to realize the installation of multiple protective nets. A connecting sleeve is arranged on one side of the limiting rib, so that when connecting two adjacent mesh frames, the two mesh frames are in an active state. In this way, when the installation is completed, when the climbing frame is subjected to external force, the two adjacent mesh frames will deviate with the external force, so that the protective net loses its protective effect on the climbing frame. When installing the protective net in the above patent, it is necessary to first install it inside the mesh frame and flatten it through a reinforced oblique square tube. When installing the reinforced oblique square tube, it is necessary to fix it by welding. In this way, when assembling the protective device, multiple processes are required. After the assembly is completed, the two adjacent mesh frames are movably connected through a rotating shaft. In this way, when installing the protective device, multiple steps are required, and the assembly is cumbersome.

[0005] Therefore, we provide a ladder protection device for an electric tower. In this device, the grid is composed of horizontal tubes and vertical tubes, which effectively ensures that the gap in the grid is small, effectively ensures the protection of personnel, and effectively ensures that no part of the personnel's body is exposed outside the climbing frame. Turning joints are provided at both ends of the vertical beams in the grid, and the turning joints are fixedly connected to the slider to effectively realize the installation of the grid. The grid can be adjusted in position under the drive of the slider, which facilitates the replacement of the grid caused by damage. Utility Model Content
