Abstract

The invention relates to a shielding device and a shielding method for live construction. The technical solution is a shielding device for live construction, including a shielding plate, a clamping block 2 is arranged on the back of the shielding plate, one side of the clamping block 2 and the shielding plate are connected by a fixed rod, and the other side of the clamping block 2 is provided with a clamping Block one, the opposite surfaces of clamping block and clamping block two are tooth shapes that cooperate with each other, and clamping block one and clamping block two are used for coordinating the angle steel or square steel of clamping steel frame electric tower. The beneficial effect of the present invention is that the toothed surface of the clamping block can match the shape of angle steel and square steel, so that the shielding device can be adapted to the electric tower with steel frame structure, and the shape fits the clamping firmly; at the same time, it is clamped by the clamping block The steel frame can directly install the shielding device at any construction position without pre-positioning it on the ground, making it more flexible to use; at the same time, the shielding method provided by the invention is easy to operate and has high 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...
