Currently, bridge plane swivel is all made of single flexural pivot rotor system, which has biggish limitation:
(1) during turning, upper load is all undertaken by flexural pivot, and the diameter of flexural pivot increases with the increase of swivel weight
Greatly, for generally swivel weight at 20,000 tons or less, flexural pivot diameter is in 3m or so, when swivel weight reaches 40,000 ton hours, flexural pivot diameter
Reach 6m or more, manufacture and transport are very difficult.
(2) single flexural pivot swivel mode is single-point support system, and in order to guarantee the stress of swivel stage top turntable, bridge pier is wide
Degree should not be too large, so that upper load is transferred directly to flexural pivot, therefore single flexural pivot swivel bridge deck width is generally less than 30m.For
Bridge deck width is greater than the bridge of 30m, and especially cable-stayed bridge needs to compress bridge pier lateral dimension, to the mechanical property of full-bridge compared with
It is unfavorable.
