Description

Technical Field

[0001] The utility model relates to a lifting device, in particular to a lifting device for a smoothing reactor with high stability. Background Art

[0002] Smoothing reactors are used in DC circuits after rectification. Since the number of pulses in the rectification circuit is always limited, there is always ripple in the output rectified voltage, and this ripple is often harmful, so it needs to be suppressed by smoothing reactors. DC transmission converter stations are equipped with smoothing reactors to make the output DC close to ideal DC.

[0003] The smoothing reactor needs to be hoisted onto the insulator platform and fixed to the insulator platform during installation. Therefore, a star frame for hoisting is usually provided on the smoothing reactor. However, the number of beams of the star frame of smoothing reactors of different models and sizes is different (usually 4, 6 or 8), and the positions of the lifting holes on the beams are also different. The main structure of the existing smoothing reactor hoist is fixed. Although the position of the shackle can be adjusted to facilitate the adaptation to the lifting holes in different positions, it cannot adapt to the star frame with different numbers of beams, which needs to be improved.
