Single-point difficult to realize turns equilibrium condition, and crossbeam Lack of support, therefore the vacant lot between swivel pier and rail track is arranged
To turn pier rotation flexural pivot center as the interim camber line track girder 2 and steel pipe support 10 in the center of circle, closed in two width of the left and right of rotating body beam
Beam bottom setting Auxiliary support 6 is set in right position, forms (3 points) support rotor systems of more fulcrums.
The Auxiliary support 6 includes beam bottom wedge adjusting block 12, column 13, intelligent support 14 and roller trolley 15 is turned up.Beam
Bottom wedge adjusting block 12 and height-regulating column 13 are for adjusting non-uniform beam height difference, and the idler wheel of roller trolley 15 is according to camber line track girder half
Diameter has been sized and dimensioned to taper, guarantees that roller trolley normally walks arc;Intelligent support 14 can with position locking hydraulic jack
Height is constant after guarantee is adjusted in place, and pressure gauge 16 and displacement meter 17 the monitoring abutment pressure and height change of setting pass through control
Terminal processed is automatically adjusted control to height of support, while guidance falls frame construction and balance weight process.
The drive system can be placed on arc track beam 2, using the automatic pushing tow technology of servo-cylinder.In arc track
Pedestal 19 is set on beam, and 20 top support foot 21 of servo pipe bending cylinder is arranged a compressed spring 18, guarantees that support foot is moved to pedestal
It struts and is supported on pedestal 19 automatically afterwards, pipe bending cylinder is protruding to be rotated with beam body, by roller trolley pushing tow to track girder
When upper next pedestal 18, pipe bending cylinder 20 retracts automatically drives support foot to be moved to next base position.On pipe bending cylinder repeats
Movement is stated, realizes that rotating body beam turns automatically.
Swivel carries out galianconism end counterweight 6 before starting, and the self diagnosis of end reaction size, control are realized by intelligent support 14
End reaction is no more than design value, saves weighing process.
Below with reference to the automatic rotation swivel construction method of the more fulcrums of pole unbalanced swivel bridge, the invention will be further described.This reality
The automatic rotation swivel construction method of the more fulcrums of pole unbalanced swivel bridge provided with new embodiment, includes the following steps:
In bridge span building railway, balance swivel range encounters when can not remove barrier, forms extremely uneven rotation
When body, at the same by counterweight be difficult meet balance swivel condition when, using multi-point support rotor system.
It arranges depending on the site environment, sets rotation flexural pivot in rotation mop, parallel railway side sets up support system, is propping up
Prefabricated beam body on frame.
Long arm end and galianconism end weight difference are too big, the equilibrium condition of real single-point swivel are only difficult by counterweight, in swivel pier
The camber line track girder using Rotary ball hinge as the center of circle is temporarily arranged in vacant lot between railway.
Auxiliary support is set at camber line track back, two width rotating body beam bottoms, the Auxiliary support includes that beam bottom wedge is adjusted
Column, intelligent support and roller trolley is turned up in block.Beam bottom wedge adjusting block and height-regulating column are fixedly connected with rotating body beam, roller trolley
On arc track beam, guarantee that Auxiliary support walks circular curve on arc track.
Auxiliary support counter-force and height are monitoring emphasis, monitor system monitoring Auxiliary support counter-force and height using intelligent support
Degree, is automatically adjusted control to height of support by controlling terminal.
The drive system is placed on arc track beam, using the automatic pushing tow of servo-cylinder.The overhanging drive of pipe bending cylinder
Beam body rotation, pipe bending cylinder automatic retracted drive support foot to be moved to next base position, and compressed spring makes support foot open branch automatically
Support is on pedestal.Pipe bending cylinder repeats above-mentioned movement, realizes that rotating body beam turns automatically.
The utility model is further described below with reference to the principle of constructing device.
Existing highway bridge rotator construction generallys use swivel pier flexural pivot single point supporting swivel method, and rotor sections almost symmetry is flat
Weighing apparatus is easy that rotor sections balance is made to realize bridge rotating by appropriate balance counterweight.But it in construction narrow space and removes tired
When difficult, often there is pole unbalanced swivel, usual single point supporting turns the more difficult smooth realization Bridge Rotation Construction Technique of method, this is practical
The construction of pole unbalanced swivel may be implemented in novel more fulcrum rotor systems.
Construction method provided by the utility model is turned according to swivel bridges unbalanced moment size and Ground arrangement in distance
The setting of flexural pivot certain distance makes using Rotary ball hinge as multiple removable adaptively additional fulcrums and its intelligent driving system in the center of circle
The reaction of supports is no more than additional support bearing capacity, supports unbalanced swivel jointly by flexural pivot and additional fulcrum, forms more fulcrums
Rotor system realizes swivel unbalanced moment and uneven counterweight, improves swivel stability.
Setting roller type adaptively supports at additional fulcrum, and counter-force self diagnosis, height is self-regulated, and rolling support can drop
Fulcrum frictional resistance is added when low swivel, can reduce weighing process, saves construction time and cost;
Continuously automatic pushing tow system, formation are longer than conventional swivel traction device for setting servo-cylinder at additional fulcrum
The arm of force and bigger rotating torque reduce swivel tractive force, and realize the intelligent control and accurate positioning of swivel overall process, construction
Convenient to be easy, economy and reliability are higher.
In the utility model embodiment Specific construction, Rotary ball hinge is set in the swivel mop of proposed bridge, it is parallel to need
It sets up bracket and builds beam body in the obstacle direction (existing railway, highway or gully) of leap;Vacant lot between swivel pier and obstacle
Circular arc shaped beam support system to turn pier as the center of circle is set, for undertaking the counter-force of additional fulcrum.The circular arc of arc roof beam structure
Radius is as big as possible to reduce the additional reaction of supports, and centering angle is greater than the angle that swivel bridges need to rotate, and at Curved beam both ends
Limited block is set, and the design of arc roof beam structure should ensure that the rigidity and requirement for bearing capacity of Curved beam.
Roller type is arranged between rotating body beam bottom and arc roof beam structure adaptively to support, double width bridge or wide bridge swivel are arranged two
Auxiliary support, the lesser single width bridge swivel of width can only be arranged an Auxiliary support, be realized by the monitoring system of setting anti-
The adaptation functions such as power self diagnosis and height self-regulation.
On arc track beam be arranged hydraulic servo pipe bending cylinder and can auto-folder, telescopic locking pedestal, by setting
The automatic control system control pushing tow system set realizes the automatic turning functions automatically continuously turned.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
