Small horizontal combined hard shielding device

Abstract

The invention discloses a small horizontal combined hard shielding device. The first movable sliding plate is arranged between the two main beams; the two opposite sides of the first movable sliding plate are slidably connected with the corresponding sides of the two main beams correspondingly. Two second movable sliding plates are slidably connected with the two main beams; the hoisting assemblyis mounted on the upper surfaces of the two main beams; the upper surface of the first movable sliding plate and the upper surfaces of the two second movable sliding plates are each provided with a movable limiting block. Three fixed limiting blocks are fixed to one of the main beams respectively, each fixed limiting block and the corresponding movable limiting block are located on the same straight line, two supporting rods are arranged, and the two ends of each supporting rod are arranged in the two main beams in a penetrating mode respectively and fixed. When the device is used for shielding, no danger is caused to a human body or a line, the shielding mounting and dismounting time is effectively shortened, the working efficiency is improved, and an effective protection interval is formed between an operator and an adjacent phase when the operator peels and overlaps each phase, so that the aims of improving the quality and the efficiency are fulfilled.

Description

technical field [0001] The invention relates to a construction equipment for high-voltage live working in a power system, in particular to a small-level combined hard shielding device. Background technique [0002] At present, there are the following problems when operators perform live work on 10KV lines: 1. In some areas where the line structure is small and horizontally arranged, since the length of the cross arm is usually about 85cm and the horizontal distance between phases is small, the danger source of live work If the traditional insulating gloves are used, it is easy to short-circuit the human body between the phases; 2. On small horizontal lines, even if the traditional insulating gloves are used for direct work, the operating procedures for insulating and shielding are cumbersome, and in the There is also a risk of short circuit during the insulation shielding process, and if the protection is carried out with the operating rod, it will take longer and increase t...
