Abstract
The utility model discloses a double-lifting pole consisting of a base, a vertical frame, a cantilever beam and double pulley lifting hooks. For the double-lifting pole fixed and arranged on a bus bridge, the base is fixed with the vertical frame; and the top of the vertical frame is fixed with the cantilever beam, the tail end of which is fixed with the double pulley lifting hooks. In the utility model, the two pulley lifting hooks on the cantilever beam of the pole are matched, one pulley block lifting hook is used for lifting a swing pipe bus, and the other pulley block lifting hook is used for lifting an insulator, therefore, the maintenance difficulty of high aloft lines can be effectively solved. The double-lifting pole has the characteristics of having safety and economy and being simple and convenient in operation, is strong in practicability and flexible in operation when working especially under the conditions of short safety distance and environment limitation; and constructors can effectively control machines and tools, prevent risk and improve the working efficiency, therefore, the requirements of on-site practical work can be met.
Description
Technical field
The utility model relates to a kind of two pole that promotes, and is used for the high voltage power transmission and transforming maintenance of track, belongs to the power industry technical field.
Background technology
In 500 kv substations, 220 kilovolts of bus support insulators have 180 posts.This series products fault in the electric power system production run takes place frequently, and needs often to change.Research by inquiry, mainly have following problem when changing the bus support insulator: 1, difficulty of construction is big.Be subjected to the restriction of operation scheme, when changing element, this interval equipment can only be had a power failure, adjacent spaces equipment needs normal operation, because very near, take place very easily that the person gets an electric shock or electrification accident (electric power safety rules regulation: with 220 kilovolts of device securities distances can not be) less than 3.0 meters with neighbouring device distance.Safety distance can't guarantee when 2, using large-scale lifting crane and bucket arm vehicle to enter the camp site.When particularly crane lifts by crane, more can't guarantee the safety distance in space, task difficulty is big, and danger coefficient is bigger, can not guarantee the person and device security during operation.3, use the construction of large-scale lifting crane and aerial platform, a crane can't be finished the replacing operation, needs two cranes to cooperatively interact and fulfils assignment.On-the-spot layout crane or aerial platform position time are long, and work-hours increases, and it is dumb to work, can't satisfy the requirement of power transformating and supplying facility reliability index, and great majority more change jobs, owing to limited by construction environment, can not use lifting crane and aerial platform operation at all.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of two pole that promotes, and is installed on the bus bridge, and the position relative fixed adopts two pulley suspension hooks to cooperatively interact to hang and changes, and can effectively solve the difficulty of above-mentioned repair and replacement.
The technical solution of the utility model is: a kind of two poles that promote are to be made of base, stand, cantilever beam, sister block suspension hook.Be fixed on the two poles that promote on the bus bridge, be fixed with stand on its base, be fixed with cantilever beam, be fixed with the sister block suspension hook at the end of cantilever beam at the stand top.Described base is that welding chassis and weld all around outside are connected to reinforced rib on base plate, is processed with through hole and by bolted connection bus bridge and adapter plate at the base plate periphery.Described stand is to be welded to form framed structure by top board, deckle board, angle steel, oblique arm-tie and flat board.Described cantilever beam is to weld two crossbeam support plates and be welded on the stand upper end with reinforced rib below crossbeam, is fixed with the sister block suspension hook on the crossbeam support plate.
The beneficial effects of the utility model are: two lifting pole direct mounts are fixed on the bus bridge, adopt two pulley suspension hooks to cooperatively interact on the cantilever beam, the use of assembly pulley suspension hook lifting pipe bus, another assembly pulley hook lifting insulator use, and can effectively solve the difficulty of high aloft maintenance of track.Have safety, economic, simple to operation characteristics, particularly under safety distance is subjected to the situation of environmental restraint for a short time, work, practical, flexible operation, the workmen is control equipment effectively, averts risks, increases work efficiency, and satisfies the requirement of on-the-spot real work.
