Problems solved by technology

[0004] However, this scheme is affected by the number of steel strands and the tonnage of continuous jacks, and the traction provided is limited
In addition, this solution can only provide a force couple in one direction, which can only rotate forward, and over-rotation needs to be strictly controlled. Once it occurs, it needs to be returned to the position through the reaction force seat. The operation is complicated and cannot be accurately aligned. High, seriously affecting production efficiency

Embodiment 1

[0025] An embodiment of the present invention provides a bridge swivel method based on a dual power mechanism, including:

[0026] The swivel operation of the bridge is carried out by the main traction swivel mechanism and / or the auxiliary traction swivel mechanism;

[0027] When the bridge overspins, the swing correction operation of the bridge is performed through the auxiliary traction swivel mechanism.

[0028] Wherein, the bridge swivel structure preferably uses the turntable 1 to carry the bridge to be swiveled, and drives the turntable 1 to rotate relative to the lower cap structure 2 to drive the to-be-swivel bridge to rotate relative to the lower cap structure 2 . For the rotatable connection structure between the turntable 1 and the lower platform structure 2, the existing spherical joint connection structure can be used, that is, the rotary connection between the turntable 1 and the lower platform structure 2 is rotatable through a ball joint pair 3; understandably,...

Embodiment 2

[0035] Such as figure 1 , an embodiment of the present invention provides a bridge swivel system based on a dual power mechanism, including a lower cap structure 2, a turntable 1 for supporting the bridge to be swiveled, and a drive for driving the turntable 1 on the lower cap structure. 2, a swivel traction device that rotates on the top, the swivel traction device includes a main traction swivel mechanism that can drive the turntable 1 to rotate forward relative to the lower platform structure 2 and can drive the turntable 1 relative to the The lower platform structure 2 is an auxiliary traction swivel mechanism for forward rotation or reverse rotation.

[0036] The above-mentioned turntable 1 is generally a cylindrical turntable, that is, its horizontal section is circular. For the structure of the above-mentioned rotatable connection between the turntable 1 and the lower platform structure 2, the existing ball joint connection structure can be used, that is, the rotary co...

Abstract

The invention relates to a bridge turning method and system based on a double-power mechanism. A main traction turning mechanism and an auxiliary traction turning mechanism are arranged, and the turning operation of the bridge is conducted through the main traction turning mechanism and / or the auxiliary traction turning mechanism; and when over-turning of a bridge occurs, the rotation amendment operation of the bridge is conducted through the auxiliary traction turning mechanism. According to bridge turning method and system based on the double-power mechanism, the auxiliary traction turning mechanism is additionally arranged, in the normal bridge turning operation, when single power is insufficient, matching of the double-power mechanism can relieve the driving burden of a single tractionturning mechanism to the great degree, thus the design of the main traction turning mechanism is correspondingly miniaturized, the problem of excessive traction equipment caused by large traction force required by large-tonnage bridge turning is better solved, and the layout of turning traction equipment is convenient. The rotation amendment operation of the bridge is conducted through the auxiliary traction turning mechanism, operation is easy, accurate positioning of the bridge is easy, and the construction efficiency and the construction quality of the bridge turning can be significantly improved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a bridge swivel method based on a double power mechanism and a bridge swivel system based on a double power mechanism. Background technique [0002] The current bridge planar balance swivel construction technology basically adopts the method of winding the steel strand around the spherical hinge turntable, and then the steel strand is stretched by continuous jacks to drive the turntable to rotate. [0003] The advantage of this method is that the construction is simple and the force is clear. Two pairs of jack tension steel strands form a pair of force couples to the turntable. When the force couples exceed the force couples formed by the friction resistance of the ball joints, the ball joints drive the upper structure to rotate around the central axis together. . [0004] However, this scheme is affected by the number of steel strands and the tonnage of ...
