Abstract
The utility model discloses a belong to a safety device of modified transmission line framework of high -tension transmission equipment scope, the modified 220kV that specifically the says so framework safety device that is qualified for the next round of competitions. Safety device carries out new setting on former transmission line framework, being supported by the cat ladder on the framework stand of being qualified for the next round of competitions and fixing the cat ladder hand protector along the vertical direction of framework stand of being qualified for the next round of competitions, equidistance welding cat ladder is marked time between two cat ladder hand protectors, and fixed cat ladder protects the cage on the cat ladder hand protector, next fixed platform support frame on the crossbeam, platform support frame both sides install platform railing, platform railing top edge fixed platform hand protector additional. The utility model overcomes working method about staff's during operation can only be stepped on the framework alternately the web member goes on avoids this kind of working method to have huge potential safety hazard, easily takes place the high altitude and falls and lead to the fact personal damage accident, and staff's life safety obtains guaranteeing.
Description
Technical field
The utility model belongs to high-voltage transmission equipment scope, and the safety device of the transmission line of electricity framework of particularly a kind of improvement is a kind of 220kV outlet structure safety device of improvement specifically.
Background technology
Ming Tombs, Beijing storage power plant 220kV outlet is divided into two, is respectively prosperous I line in mound, prosperous II line in mound.220kV high-voltage terminal framework adopts full steel structure surface granosealing, be made up of three variable cross-section truss columns and two square cross-section girder trusses, frame girder, post all adopt intersection web member system, framework height is 15m, girder truss span is 15m, ground terminal is arranged in truss column top, and be highly 4.5m, nineteen ninety-five comes into operation.Every bar 220kV outlet A, B, C three-phase is connected with framework with two insulator strings respectively, and will carry out insulation measurement to insulator every year, staff will go up on gate framework crossbeam and measure.Framework does not have cat ladder and pavement and guardrail, staff can only step on framework intersects web member and carries out up and down and work, and this kind of mode exists huge potential safety hazard.When climbing not protection and crossbeam work up and down, easily there is falling from high altitude and causing personal injury accidents, be therefore badly in need of transforming climbing framework during measurement insulator and crossbeam working method.
Utility model content
The purpose of this utility model is the deficiency of the device security hidden danger for the existence of 220kV outlet structure, a kind of safety device of transmission line of electricity framework of improvement is proposed, it is characterized in that, the safety device of described transmission line of electricity framework arranges framework cat ladder, pavement and platform guardrail on former transmission line of electricity framework; Outlet structure column is supported by cat ladder and is fixed along outlet structure column vertical direction by cat ladder handguard, between two cat ladder handguards, equidistant welding cat ladder is marked time, and cat ladder is fixed by cat ladder handguard and protects cage; Secondly fixed platform bracing frame on crossbeam, platform frame both sides install platform railing additional, platform railing top edge fixed platform handguard.
Tiling steel plate in described platform frame.
It is semi-circular that described cat ladder protects cage.
The beneficial effects of the utility model overcome can only to step on framework when staff works and intersect web member and carry out upper and lower working method, this kind of working method is avoided to there is huge potential safety hazard, easy generation falling from high altitude causes personal injury accidents, and the life security of staff is guaranteed.

Detailed description of the invention
The utility model proposes a kind of safety device of transmission line of electricity framework of improvement, is a kind of 220kV outlet structure safety device of improvement specifically.Below in conjunction with accompanying drawing, the utility model is explained.
Figure 1 shows that outlet structure schematic diagram.The safety device of the framework of transmission line of electricity shown in figure on outlet structure column 3, supports 5 by cat ladder fixed along outlet structure column 3 vertical direction by cat ladder handguard 6, between two cat ladder handguards 6, equidistant welding cat ladder marks time 7, cat ladder handguard 6 is fixed cat ladder and protect cage 4, it is semi-circular (as shown in Figure 2,3, 4) that described cat ladder protects cage.
Secondly fixed platform bracing frame 8 on crossbeam 2, platform frame 8 both sides install platform guardrail 1 additional, and the steel plate 9 (as shown in Figure 5) that tiles in platform frame 8; At the top edge fixed platform handguard 10 (as shown in Figure 5,6) of platform guardrail 1;
When staff works, no longer climb framework and intersect web member and carry out up and down, from cat ladder up and down, and protect in cage 4 at cat ladder and hold cat ladder handguard 6, pin is stepped on cat ladder and is marked time about 7; On platform on crossbeam 2 during operation, have tiling steel plate 9 and platform bracing frame 8 both sides to install platform guardrail 1 additional and escort, avoid that falling from high altitude occurs and cause personal injury accidents, the life security of staff is guaranteed.
