Abstract
The utility model relates to a 220kV tunable power transformation hot-line operation platform, which belongs to the field of hot-line operation tools. The 220kV tunable power transformation hot-line operation platform consists of a trestle ladder, a horizontal ladder, and an operation board, wherein the trestle ladder is composed of two ladder assemblies movably connected at the upper ends; the top of the trestle ladder is horizontally connected with the horizontal ladder; the operation board is fixed at the middle part of the horizontal ladder; and support rods are connected between the horizontal ladder and the trestle ladder. According to the technical scheme, the 220kV tunable power transformation hot-line operation platform provided by the utility model is quick and convenient in field assembly, and can effectively lower the operation intensity and reduce the construction security risk. The acting point of the whole operation structure is directly supported on the ground, and can adjust the angle and direction of operators entering the strong electric field according to the actual arrangement manner of power transformation equipment, thereby ensuring reasonable and effective hot-line operation safety distance and combination gap of equal potential working electricians when entering the strong electric field and conducting construction operation. The operation platform can improve the operation safety and comfort degree of operators to meet the requirement for hot-line operation of 110kV and 220kV power transformation equipment.
Description
Technical field
The adjustable power transformation live line working of the 220kV of the utility model platform belongs to the tools for live working field.
Background technology
In the prior art; The main mode that hot line maintenance gets into highfield is with rope ladder peace ladder; Because the line facility combiner is fairly simple; The live line working safe distance, combinational gap controls easily, but in the transformer station Equipment Design with arrange relative compact, so in transformer station, use rope ladder peace ladder all can receive bigger limitation; In transformer station, use flat ladder, can only an end be fixed on the converting equipment stand, the other end relies on the control rope to control; Its stability receives the influence of fixed form; The angle of setting all compares difficulty with the adjustment of height, and the residing setting of operating personnel is difficult to control, and security risk is bigger; Flat ladder is the passage that gets into equal potential working point in live line working; And there is not to supply the platform of staff's operation in the transformer station on the apparatus body; Bring certain difficulty for the enforcement of operating personnel's practical operation behavior and safety measure, increased the difficulty of operation virtually.
Summary of the invention
The purpose of the utility model is to propose the adjustable power transformation live line working of a kind of 220kV easy to use, simple in structure, that coefficient of safety is high platform.
The purpose of the utility model is achieved in that the adjustable power transformation live line working of 220kV platform is made up of double ladder, flat ladder, operation plate.Article two, the ladder of the active connection in upper end is formed double ladder, and the double ladder top, horizontal is connected with flat ladder, is fixed with operation plate at flat ladder middle part, is connected with support bar between flat ladder and double ladder.
Because implement technique scheme, the utlity model has following advantage: 1, site installation is quick and easy, the earth potential that need not step on work high above the ground such as bar, last portal frame cooperates, and can effectively reduce operation intensity and reduce construction safety risk; 2, the use of double ladder passage make the entire job framework impetus directly by ground loading; And increase anti-skidding foot of ladder; Can be according to the actual arrangement mode of converting equipment; The adjustment operating personnel gets into the angle and direction of highfield, can guarantee the equal potential working electrician get into highfield with implement to keep in the operation process rational and effective live line working safe distance, combinational gap; 3, in the double ladder top design job platform that is made for industry personnel concrete operation behaviour, the design indicates of hommization goes out the security management and control principle that people-oriented, improves fail safe and the comfort level of operating personnel in operation process; 4, in the double ladder channel design, increased gaily decorated basket screw rod group; In order to firm ladder and the folding angle of regulating double ladder; To reach the effect of adjustment operation height; Activity space in 3.5-5.0 meters scopes can be provided, with the demand of the live line working of satisfying 110kV and 220kV electric pressure converting equipment.
Description of drawings:
The concrete structure of the utility model is provided by following accompanying drawing and embodiment:
Fig. 1 is the adjustable power transformation live line working of a 220kV platform structure sketch map.
Legend: 1, flat ladder, 2, operation plate, 3, support bar, 4, expansion link, 5, double ladder, 6, anti-skidding skirt.
Embodiment:
The utility model does not receive the restriction of following embodiment, can confirm concrete execution mode according to the technical scheme and the actual conditions of the utility model.
Embodiment: as shown in Figure 1, the adjustable power transformation live line working of 220kV platform is made up of double ladder 5, flat ladder 1, operation plate 2.Article two, the ladder of the active connection in upper end is formed double ladder 5, and double ladder 5 top, horizontal are connected with flat ladder 1, are fixed with operation plate 2 at flat terraced 1 middle part.Flat ladder 1 and 5 of double ladders are connected with support bar 3.
Through the installing/dismounting section whether every group of ladder is to be made up of last ladder, ladder, and the dismounting section that is connected between upper and lower ladder down,, can adjust the height of the adjustable power transformation live line working of 220kV platform.Going up in twos the ladder lower end, be connected with expansion link between the ladder upper end down, said expansion link is a gaily decorated basket screw rod group, in order to firm ladder and the folding angle of regulating double ladder 5, to reach the effect of adjustment operation height.
Double ladder 5 bottom work are connected with anti-skidding foot of ladder 6, can effectively increase the frictional force with ground.
Said double ladder 5 is insulator with operation plate 2.
During use, confirm to regulate expansion link 4 length, thereby confirm the opening angle of double ladder 5, subsequently with expansion link 4 location according to actual conditions.The operating personnel climbs to operation plate 2 places through double ladder 5, and seat can carry out work on operation plate 2.
Above technical characterictic has constituted the most preferred embodiment of the utility model, and it has stronger adaptability and best implementation result, can increase and decrease inessential technical characterictic according to actual needs, satisfies the needs of different situations.
