The crane is adopted to lift the cable very time-consuming and labor-consuming, and the installation efficiency is not high. Meanwhile, a large amount of dust can enter the valve hall due to the fact that the crane enters and exits the valve hall, and the working environment of the converter valve is seriously affected. In addition, after the valve module or the submodule fails, if a valve hall lifting platform is adopted, only one submodule can be replaced at a time, the failure first-aid repair time is greatly prolonged, and the energy availability of a direct-current system is reduced. A special hoisting device is needed, so that the fault processing time is shortened, the personnel investment is reduced, the working efficiency is improved, and the energy availability of a direct current system is improved.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a can not influence the operational environment of converter valve, shorten valve module or submodule piece fault handling time, reduce the device that flexible direct current converter valve lifted by crane of personnel's input.
The utility model adopts the technical proposal that: the utility model provides a flexible direct current converter valve hoisting accessory of snake type, includes that transverse section is the hanging beam of cell type or I-shaped, the whole shape of hanging beam is the snake type, and the horizontal trajectory of snake type is the same with the horizontal distribution orbit of flexible direct current transmission converter valve tower, and hanging beam fixed mounting is on the steel framework in flexible direct current valve room, and the position is located directly over the converter valve tower, be equipped with the traveling motor on the hanging beam up end, the lower terminal surface of hanging beam is equipped with electronic loop wheel machine.
Furthermore, the hanging beam is installed on a steel framework of the flexible direct current valve hall through bolts.
Furthermore, a movable rotating shaft is arranged at each bending part of the hanging beam, and the hanging beams on two sides of the movable rotating shaft can rotate around the movable rotating shaft.
Furthermore, the tail end of the hanging beam is provided with a limiting device for preventing the walking motor and the electric crane from sliding off.
Further, the limiting device is a photoelectric sensor.
The utility model has the advantages that: compared with other structures, the snake-shaped structure has the advantages of less requirements on a hoisting device and low cost. The flexible direct current converter valve has the advantages of less investment, simple and convenient equipment operation, short time cost, improvement of working efficiency, reduction of installation and fault first-aid repair time of the flexible direct current converter valve, improvement of the energy availability of a direct current system, obvious economic benefit, safety, reliability and easiness in popularization.
