Combined assembly type high-voltage live-line work comprehensive shielding device and using method thereof

Abstract

The invention relates to a combined assembly type high-voltage live-line work comprehensive shielding device and a use method thereof. The combined assembly type high-voltage live-line work comprehensive shielding device comprises a first shielding cover and a second shielding cover, and the first shielding cover and the second shielding cover are the same in structure and are both frame body structures with bottom openings; the adjacent sides of the first shielding cover and the second shielding cover are provided with a positioning block and a positioning groove respectively, and the positioning block and the positioning groove are connected in an inserted mode; and a left fixing base and a right fixing base which can be connected through bolts are fixed to the top of the first shieldingcover and the top of the second shielding cover respectively. The shielding device has the advantages that the shielding covers can stably and quickly move on wires by utilizing pulleys, so that theshielding covers are more convenient to use. According to the shielding device, the wires of different specifications can be clamped and fixed conveniently, the stability of the shielding covers on the wires can be improved, and the heat dissipation effect of the wires in the shielding covers is improved. Through the positioning block, the positioning groove and the bolts, positioning, mounting and fastening of the first shielding cover and the second shielding cover are facilitated, and combination and splicing of the second shielding cover and the first shielding cover are achieved.

Description

Technical field [0001] The invention relates to a combined and assembled type high-voltage live working comprehensive shielding device and a use method. Background technique [0002] The insulating shield is made of insulating materials and is used to shield live conductors or non-charged conductor parts. In live work tools, the shield does not have the main insulation function. It is only suitable for accidental short-term collisions of live workers Time, that is, when rubbing the contact, it plays the role of insulation and shielding or isolation. [0003] However, when the existing shielding cover used for conducting wire during live operation is in use, its internal mechanism is used to fix the conducting wire, which usually adopts a fixed semicircular structure, which makes it difficult to fix wires of different specifications. After the wire shield is fixed on the wire, it is difficult to move horizontally. Even if it can be moved, it is easy to damage the wire and is inconv...

Problems solved by technology

[0003] However, when the shielding cover used for wires in the existing live working process is in use, the internal mechanism for fixing the wires usually adopts a fixed semicircular structure, which is difficult to fix wires of different specifications, and the existing After the wire shielding cover is fixed on the wire, it is difficult to move horizontally. Even if it can be moved barely, it is easy to cause damage to the wire and is inconvenient to use. At the same time, the existing wire shielding cover cannot be spliced ​​and assembled. When the wires are insulated and shielded, only two independent shielding covers can be used to insulate and shield the wires respectively, which is not only inconvenient to use and carry, but also there is a gap between the two independent shielding covers, which poses a certain safety hazard
