Abstract
The present invention relates to a light-type vertically-turning opening bridge. It includes a main frame, said main frame is composed of oblique tower and bridge floor, said oblique tower is connected with one end of said bridge floor, and said one end where the oblique tower and bridge floor are mutually connected is set on the base seat and is turnably connected with said base seat, between said oblique tower and bridge floor an oblique guy rope is set and two ends of said oblique guy rope are respectively connected with said oblique tower and bridge floor, on the main frame a balance weight block is set, and said balance weight block can be slidden on said main frame.
Description
Technical field
The present invention relates to a kind of bridge, relate in particular to a kind of light bascule opening bridge that can open, close.
Background technology
In the present prior art, movable bridge adopts the semi girder configuration equilibrium pressure pouring weight opposite with cantilevered orientation to constitute more.Because what such movable bridge adopted is the form of structure of semi girder, the deadweight of beam itself is inevitable bigger, the weight of the equilibrium pressure pouring weight supporting with it is then bigger, so the weight of class movable bridge is generally all very big, and the weight of opening section has decisive influence to the overall cost of engineering, so such movable bridge is not promoted in engineering practice as yet.
Summary of the invention
The invention provides a kind of light bascule opening bridge that can reduce opening structure weight.
The present invention adopts following technical scheme:
A kind of light bascule opening bridge, comprise: main frame, this main frame is made up of leaning tower and bridge floor, leaning tower is connected with an end of bridge floor, the interconnective end of leaning tower and bridge floor is located on the pedestal and with pedestal and is rotationally connected, the two ends that are provided with suspension cable and suspension cable between leaning tower and bridge floor are connected with bridge floor with leaning tower respectively, are being provided with the equilibrium pressure pouring weight that can slide on main frame on the main frame.
Compared with prior art, the present invention has following advantage:
The present invention combines opening structure with the leaning tower cable stayed bridge, leaning tower is both as the balance ballast of bridge floor girder, again as the external elastic support structure of bridge floor girder, thereby has reached the organic unity of balance ballast and structure stress.Because what the present invention adopted is the form of structure of leaning tower cable stayed bridge, in striding, bridge floor have some suspension cables that elastomeric bearing is provided, thereby girder can design more very thinly, the deadweight nature is lighter, the leaning tower weight supporting with it is then also lighter, but so the opening section construction weight of class movable bridge can design relatively merrilyyer and lightheartedly.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is another embodiment of the present invention topology view.
Fig. 3 is a whole machine balancing schematic diagram of the present invention.
Fig. 4 is that the present invention opens the back schematic diagram.
The specific embodiment
A kind of light bascule opening bridge, comprise: main frame, this main frame is made up of leaning tower 1 and bridge floor 2, leaning tower 1 is connected with an end of bridge floor 2, leaning tower 1 is located on the pedestal and with pedestal with bridge floor 2 interconnective ends and is rotationally connected, the two ends that are provided with suspension cable 3 and suspension cable 3 between leaning tower 1 and bridge floor 2 are connected with bridge floor 2 with leaning tower 1 respectively, are being provided with the equilibrium pressure pouring weight 4 that can slide on main frame on the main frame.Being provided with specifically of equilibrium pressure pouring weight 4 can be adopted following technical measures: (1) equilibrium pressure pouring weight 4 is located on the leaning tower 1, is provided with pulley on leaning tower 1, and equilibrium pressure pouring weight 4 is connected in motor by the rope that is located on the pulley.(2) equilibrium pressure pouring weight 4 is located on the bridge floor 2, and equilibrium pressure pouring weight 4 is connected in motor by rope.
The present invention is the form of structure that adopts no dorsal funciculus leaning tower cable stayed bridge.This form of structure can be used in the movable bridge of flatting turn, and also can be used in upright the commentaries on classics in the movable bridge.
1. in the time of in being used in the movable bridge of flatting turn, in moving process, this lightweight structures form is the same with the form of structure of the supporting balance ballast of traditional semi girder, and center of gravity is on shaft axis.So being connected of this light-duty opening structure and bottom buttress, and that the device that turns on the power etc. can be with traditional movable bridge is identical.
2. in the time of in being used in upright commentaries on classics movable bridge, in moving process, the structural focus invariant position of the supporting balance ballast of the traditional semi girder form of comparing, the structural focus position of this bridge are constantly to change, and therefore are necessary whole moving process is done comparatively detailed discussion.
The upright whole machine balancing schematic diagram that changes movable bridge is seen Fig. 3.Among the figure, Wt is the weight of leaning tower AB, and S is the projected length of leaning tower AB on girder BD axis direction, and Wb is the weight of girder BD, and L is the length of girder BD, and the angle of cut of leaning tower AB and girder is β.
We set, and the quality edge of tower, beam axis direction separately evenly distributes, and do not consider the influence of structure rotation momentum in moving process, and then under the free position in moving process, the design parameters of opening structure each several part must satisfy:
In the formula, θ is the opening angle of movable bridge, as shown in Figure 4.M
θFor opening mechanism when opening angle is θ, the folding moment values to the folding hinged-support that need provide to opening structure.
In moving process, the opening section structural focus of movable bridge is being opened on the rotating shaft all the time, when if relative its span of the bridge deck width of movable bridge is narrower, still should notes checking, and carry out corresponding detail structure processing at solid node of tower beam and rotating shaft place to the lateral, plane of bridge is stable.
