Abstract

The invention relates to a shielding device and a shielding method for live-line construction. According to the technical scheme, the shielding device for live-line construction comprises a shieldingplate, a second clamping block is arranged on the back face of the shielding plate, one face of the second clamping block is connected with the shielding plate through a fixing rod, a first clamping block is arranged on the other face of the second clamping block, and the opposite faces of the clamping block and the second clamping block are in tooth shapes matched with each other. The first clamping block and the second clamping block are used for clamping angle steel or square steel of a steel frame electric tower in a matched mode. The shielding device has the beneficial effects that the tooth-shaped surfaces of the clamping blocks can be matched with the shapes of the angle steel and the square steel, so that the shielding device can be matched with the electric tower with a steel frame structure, and the shapes are fit and clamped firmly; meanwhile, the clamping blocks are matched with the clamping steel frame, the shielding device can be directly installed at any construction position, the shielding device does not need to be placed on the ground in advance, and use is more flexible; and meanwhile, the shielding method provided by the invention is convenient to operate and high in safety.

Description

technical field

[0001] The invention relates to the field of electric power construction equipment, in particular to a shielding device for live construction and a shielding method for live construction. Background technique

[0002] In the "10kV Overhead Distribution Line Live Work Management Regulations", it is stipulated that during low-voltage live work, an effective distance of not less than 0.3 meters should be maintained. If the safe distance cannot be ensured, insulating baffles, pipes, cloth and others should be used. Insulation measures.

[0003] In the prior art, a pole shield disclosed in patent document CN107834426B includes two sleeve-type covers that can slide up and down relative to each other, which can effectively shield the poles. However, this shielding cover is only suitable for cylindrical utility poles, and cannot be used for electric towers that are widely used in substations or suburbs by angle steel or square steel, and the sleeve cover needs to be...
