Description
Technical field
The invention belongs to the bridge technology field, particularly relate to a kind of bridge rotator construction structure.
Background technology
Because the particularity of bridge construction in bridge construction process, need be used multiple construction technology, the bridge rotator construction is wherein important a kind of.Rotator construction is with respect to other form of construction work, and difficulty of construction is bigger, but because its traffic impact to the road crossover location is minimum, often adopts in the present bridge construction.
Be to reduce the overall structure center of gravity, with the operation of turning of bridge pier and beam body integral body, common method is the method for flatting turn usually.
The rotor system of the method for flatting turn mainly contains the rotating support system, rotates trailer system and balance sysmte.The rotating support system is the key equipment that the method for flatting turn is constructed, and is made up of top rotary table and lower rotary table.Top rotary table supporting rotational structure, lower rotary table and basis link.Rotate with respect to lower rotary table through top rotary table, reach the purpose of turning.
Multiple functions such as the rotating support system must take into account and turn, load-bearing and balance.Equilibrium conditions when pressing rotating support, rotating support can be divided into mill heart supporting, spike supporting and the mill heart and support three types jointly with spike.
A key issue that exists in the process of flatting turn is the equilibrium problem in the process of turning.Rotate center of gravity and be generally the bridge pier axle center, reduce for making center of gravity, usually rotating disk is located at pier at the bottom of, need to add the purpose that counterweight has reached balance in the rotation.
Generally bear whole rotation weight, be inserted with positioning rotating shaft at the mill heart usually by the mill heart.In order to guarantee safety, around supporting turntable, be provided with thrust wheel or feet usually.During normal rotation, thrust wheel or supporting foot do not contact with chute surface, in case have topple the tendency then play supporting role.
But some bridge is because the particularity of its geographical position of living in and this body structure, can't adopt scheme of rotation at the bottom of the pier, has railway line to pass through in the bridge bottom, and allows just must adopt rotator construction under very short situation break period.Each bridge pier is made up of two parts, can't adopt and rotate constructure scheme at the bottom of the pier.So a kind of security performance of necessary design is good, the bridge rotator construction structure of easy construction.
Summary of the invention
It is good that the object of the invention just provides a kind of security performance, has railway line to pass through in the bridge bottom, and allow under very short situation break period can convenient construction bridge rotator construction structure.
The object of the invention is realized through following technical proposals:
A kind of bridge rotator construction structure comprises beam body and bridge pier, also comprises vertical force bearing, spherical twisted axis, slip casing, cable wire, directive wheel, reaction frame, jack, the auxiliary pier of rotating; The beam body is connected with bridge pier with the spherical twisted axis that rotates through the vertical force bearing, and the bridge pier end face has deep-slotted chip breaker, and the vertical force bearing places this deep-slotted chip breaker; And corrosion resistant plate is laid in the deep-slotted chip breaker bottom surface, and vertical force bearing lower surface is provided with polyfluortetraethylene plate, connects through binder between the bridge pier; Spherical rotation twisted axis is installed in the binder middle part and is connected with the beam body; Slip casing upper end is fixed on beam end of body bottom surface, and the lower end contacts with bridge pier, and reaction frame is arranged at bridge pier top also anchoring; Jack one end is fixed on the reaction frame; The other end connects an end of cable wire, and the other end of cable wire is anchored on the slip casing, and contacts with a plurality of directive wheels that are arranged on the bridge pier top outer wall along beam body rotation tangential direction in the middle of the cable wire; Beam body below is symmetrically arranged with two auxiliary piers with beam body length vertical direction, and corresponding bridge pier is provided with the identical cable wire of function, directive wheel, reaction frame and jack on the auxiliary pier.
Further, offer anchor hole on the said slip casing, an end of cable wire is through this anchor hole and the anchoring of slip casing.
Beneficial effect of the present invention is: safety is good, has railway line to pass through in the bridge bottom, and allows can construct easily under the very short situation break period, and not only velocity of rotation is fast, and can peak discharge reduces the break period of road under the bridge.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 be among Fig. 1 A to enlarged drawing;
Fig. 3 is the present invention's schematic diagram of constructing.
The specific embodiment
As depicted in figs. 1 and 2, a kind of bridge rotator construction structure comprises beam body 1 and bridge pier 3; Also comprise vertical force bearing 7, spherical twisted axis 6, slip casing 2, cable wire, directive wheel 4, reaction frame 8, jack 9, the auxiliary pier 10 of rotating, beam body 1 is connected with bridge pier 3 with the spherical twisted axis 6 that rotates through vertical force bearing 7, and bridge pier 3 end faces have deep-slotted chip breaker to adapt to the needs of turning; Vertical force bearing 7 places this deep-slotted chip breaker, and deep-slotted chip breaker bottom surface laying corrosion resistant plate, and vertical force bearing 7 lower surfaces are provided with polyfluortetraethylene plate; Connect through binder 5 between the bridge pier 3, spherical rotation twisted axis 6 is installed in binder 5 middle parts and is connected with beam body 1, and plays position-limiting action; Slip casing 2 upper ends are fixed on beam body 1 end bottom surface; The lower end contacts with bridge pier 3, and bears the tension in the rotation, and reaction frame 8 is arranged at bridge pier 3 tops also anchoring; Jack 9 one ends are fixed on the reaction frame 8; The other end connects an end of cable wire, and the other end of cable wire is anchored on the slip casing 2, and contacts with a plurality of directive wheels 4 that are arranged on the bridge pier 3 top outer walls along beam body 1 rotation tangential direction in the middle of the cable wire; The glide direction that makes cable wire plays the effect that reduces to rub with correct guidance all the time along the tangential direction of turning and rotating; Beam body 1 below and beam body 1 length vertical direction are symmetrically arranged with two auxiliary piers 10; Corresponding bridge pier 3 is provided with the identical cable wire of function, directive wheel, reaction frame and jack (not drawing among the figure) and is used for rotating when occurring stagnating at beam body 1 auxiliary afterburning on the auxiliary pier 10, accomplishes construction.This auxiliary pier 10 is used for bearing at rotator construction and occurs that beam body 1 two ends unbalance stress causes and the gravity that occurs, in case beam body 1 topples.
As shown in Figure 3, when construction, bridge pier 3 both sides jack 9 constantly spur cable wire along the revolution tangential direction while application of force rotates beam body 1, and central spherical is rotated twisted axis 6 and under the effect of power, rotated, and carries out spacing.Two vertical force bearings 7 of beam body 1 both sides slide along bridge pier 3 top arc areas, and slide plane is polyfluortetraethylene plate and corrosion resistant plate contact surface.If, can start jack pair beam body 1 application of force on the auxiliary pier 10, be rotated further in the rotation process because of factors such as frictional force increase cause rotate stagnating.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
