L-shaped clamp-adopted steel pipe signboard stretchable frame

Abstract

The invention discloses an L-shaped clamp-adopted steel pipe signboard stretchable frame, and belongs to the technical field of electric power system signboard installation devices. The L-shaped clamp-adopted steel pipe signboard stretchable frame comprises a first L-shaped mounting frame and a second L-shaped mounting frame, the second L-shaped mounting frame is mounted on a cross-shaped structure, wherein the cross-shaped structure comprises a linear horizontal frame, one end of the linear horizontal frame is mounted on the second L-shaped mounting frame, the other end of the linear horizontal frame is arranged to be of a slot type structure, a horizontal extension plate is inserted into the slot type structure, a vertical frame body perpendicular to the linear horizontal frame is weldedto the position, close to the slot type structure, of the linear horizontal frame, the upper end and the lower end of the vertical frame body each are arranged to be of a slot type structure, and vertical extension plates are inserted into the corresponding slot type structures, and bolt mounting holes are formed in the first L-shaped mounting frame, the second L-shaped mounting frame, the linearhorizontal frame, the vertical frame body, the horizontal extension plate and the vertical extension plates. The L-shaped clamp-adopted steel pipe signboard stretchable frame can be universally usedfor mounting of signboards of various sizes, the mounting process is fast, and the mounting effect is good.

Description

technical field [0001] The invention relates to an L-shaped fixture steel pipe identification plate expansion frame, which belongs to the technical field of electrical system identification plate installation devices. Background technique [0002] Every base and tower of the power line should be equipped with eye-catching signs (line name, voltage level, tower number, warning slogan, phase sequence, etc.). [0003] In recent years, steel pipe poles have been widely used due to their significant advantages such as high strength, small footprint, and the ability to erect on the same pole to save line corridors, accounting for more than 40% of line poles and towers. However, due to the diversification of structural types, there is no uniform installation position of the signboard, which affects both the early installation and later replacement of the signboard, which brings troubles to the operation and maintenance of power lines and cannot meet the requirements of lean managem...

Problems solved by technology

However, due to the diversification of structural types, there is no uniform installation position of the signboard, which will affect both the early installation and later replacement of the signboard, which brings troubles to the operation and maintenance of power lines and cannot meet the requirements of lean management of power line equipment

[0004] The existing steel pipe rod identification plate is generally installed on the ladder pipe column with a circular clamp bracket, but there is no uniform standard for the ladder type, and there are too many types. The effect is very unsatisfactory, and there are potential safety hazards. There is no suitable installation bracket in stock when replacing and supplementing missing signs. They are often tied with iron wires to the steel pipe pole ladder. This method is not firm, unsightly, and easily lost. Affect the correct judgment of the operation, maintenance and maintenance personnel on the tower, resulting in wrong boarding of the tower

[0005] At present, the voltage levels are generally divided into 35KV-110KV, 220KV-330KV, 750KV, 880KV-1000KV, among which the 35KV-110KV line pole plate specification: length 400mm, width 320mm; 220KV-330KV line pole plate specification: length 50mm, width 400mm, 750KV line pole number plate specification: length 600mm, width 480mm, 800KV-1000KV line pole number plate specification: length 480mm, width 300mm, line voltage level is different, the size of the identification plate is also different, and the type of identification plate is different, the voltage level Different, the size of the marking plate is also different, the smallest is 200mm*200mm, the largest is 770mm*570mm, currently there is no universal mounting bracket for different sizes of marking plate on the market, which is not conducive to daily emergency and spare parts management
