The arc-shaped gate comprises a gate leaf structure, a main cross beam and two sets of supporting arms, wherein the main cross beam is arranged on the gate leaf structure; the two sets of supporting arms are arranged in a calculating plane of a main frame; each set of the supporting arms is composed of two or more branch supporting arms; one end of each of the branch supporting arms is in dispersed connection with the main cross beam while the other end is connected with a supporting hinge; and the corresponding supporting hinges of all sets of supporting arms are connected into an integrated compound hinge. Compared with the conventional arc-shaped gate, the arc-shaped gate with the multi-supporting-arm compound hinge structure provided by the utility model has the advantages that a calculating internal force of the main beam is greatly reduced, and meanwhile, the axial pressure and the end part bending moment endured by each supporting arm at the corresponding supporting position of the main beam are correspondingly reduced, the force endured by the supporting hinges of the gate is more uniform, the stressed conditions of the main beam, the supporting arms and the supporting hinges are improved, and a stressed structure of the gate is optimized.
Description
Technical field
The utility model relates to field of water conservancy, relates in particular to be used for the Segment gate that Hydraulic and Hydro-Power Engineering adopts the compound hinge structure of many support arms, is particularly useful for big aperture etc. and bears the Segment gate than the big flood press loading effect.
Background technology
Segment gate is a dash facility important in the Hydraulic and Hydro-Power Engineering; Its main force structure is made up of log type gate leaf and its, support arm structure and support hinge device etc.; Concerning main beam formula Segment gate, gate stress frame shape is like " π " shape, under the hydraulic pressure load action; The gate girder can be considered the simply-support structure that the two ends cantilever bears evenly distributed load, and support arm is the eccentric compression-member that there is moment of flexure the end.Concerning the Segment gate of big aperture and middle high water head; The hydraulic pressure load that gate bears is very big; The shearing at the mid span moment of gate girder, bearing place and the axial compression of support arm are all bigger; Design to gate girder, support arm and other pressure-bearing component will cause very big difficulty, and therefore each member can design comparatively big and heavyly, is unfavorable for making, lifting and the transportation of gate.
The utility model content
The purpose of the utility model be to provide a kind of make that gate props up hinge stressed evenly, improved the force-bearing situation of girder, support arm, a hinge, be beneficial to the Segment gate that Hydraulic and Hydro-Power Engineering adopts the compound hinge structure of many support arms that is used for of the stability that improves support arm.
The technical scheme of the utility model employing is following to achieve these goals:
Be used for the Segment gate that Hydraulic and Hydro-Power Engineering adopts the compound hinge structure of many support arms; Comprise log type gate leaf and its and be arranged on the main beam on the log type gate leaf and its that comprise that also being located at main frame calculates two groups of support arms in the plane, every group of support arm is made up of branch's support arm that two or more are located in the main frame calculating plane; One end of each branch's support arm disperses to be connected with said main beam; The other end connects a hinge respectively, and every group of each corresponding hinge of support arm links to each other, and forms to have integrally-built compound hinge.
Preferably, the integrative-structure that is formed in one of said compound hinge.
Preferably, said compound hinge is served as reasons independently to prop up and is formed by the hinge series connection after the hinge free bearing is concentrated in parallel the placement again.
Preferably, every group of support arm is made up of two branch's support arms that are located in the main frame calculating plane, and each branch's support arm adds allotment arm pattern with being connected of main beam with oblique support arm or oblique support arm and connects.
Preferably, every group of support arm is made up of three branch's support arms that are located in the main frame calculating plane, and branch's support arm was connected with an allotment arm pattern with being connected with two oblique support arms of main beam.
The beneficial effect of the utility model is following:
The compound hinge structure of the many support arms Segment gate of the utility model is the continuous girder structure that the main beam stress pattern of gate is changed into two ends cantilever, middle many point supportings; Under equal conditions, compare with Segment gate commonly used, the calculating internal force of girder will reduce greatly; Simultaneously; The axial compression that each support arm at the corresponding bearing position of girder place bears is also corresponding with the end moment of flexure to be reduced, and gate props up the stressed also more even of hinge, has improved girder, support arm, a force-bearing situation that cuts with scissors significantly; The stability Design that helps support arm has been optimized the force structure of gate.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the technical scheme of the utility model is further described.
Main frame calculates the calculating plane that can bear the external force load that the plane is meant that main beam and coupled support arm belong to.
Embodiment shown in Fig. 1～3 is in the gate main frame calculates the plane, is designed with two groups of support arms, and each is organized support arm and is connected the external force load when q has represented the gate use respectively through compound hinge 2 with main beam 3; Every group of support arm is made up of two branch's support arms 1, and each branch's support arm 1 all is arranged on main frame and calculates in the plane.Each branch's support arm 1 connected with being connected with oblique support arm pattern of main beam 3; Each branch's support arm 1 connects with a mode that is connected by conventional Segment gate of hinge; The hinge free bearing that branch's support arm of every group of support arm is corresponding links and has constituted compound hinge 2; Compound hinge 2 can be the hinge structure of integral body as shown in Figure 2, also can be the structure that is in series through hinge 5 again after concentrating parallel connection to place by each hinge free bearing 6 as shown in Figure 3.
Fig. 4～6 illustrated embodiments are in the gate main frame calculates the plane, being provided with two groups of support arms, and are same, and each is organized support arm and is connected the external force load when q has represented the gate use respectively through compound hinge 2 with main beam 3; Every group of support arm is made up of three branch's support arms 1; Each branch's support arm 1 all is arranged on main frame and calculates in the plane; Branch's support arm 1 was connected with an allotment arm pattern with being connected with two oblique support arms of main beam 3; Each branch's support arm 1 connects with a mode that is connected by conventional Segment gate of hinge; The hinge free bearing that the branch support arm of every group of support arm is corresponding links and has constituted compound hinge 2, and compound hinge 2 can be the hinge structure of integral body as shown in Figure 5, also can be the structure that is in series through hinge 5 again after concentrating parallel connection to place by each hinge free bearing 6 as shown in Figure 6.
