Abstract
The utility model discloses a main beam type support arm frame structure for a radial gate, which comprises a main beam, wherein a support arm frame formed by two symmetrically arranged Y-shaped frames is arranged on the main beam, and the tail ends of the support arm frame are hinged with auxiliary hinges of the radial gate. The support arm frame is a double-Y structure formed by rigidly connecting straight support arms and sharp point ends of V-shaped support arms. Two support legs at the open ends of the V-shaped support arms are in rigid connection with the main beam. With the adoption of the technical scheme disclosed by the utility model, as well as the double-Y-shaped support arm frame structure of the main beam, the structural stability is enhanced and the safe operation of the gate is ensured; through increase of rigid connection points for the support arms and the main beam, the mid-span of the main beam and the bending moment of the suspension support arm section are reduced, and further, the cross section size of the main beam is reduced, the project investment is saved, and the popularization is facilitated.
Description
Technical field
The utility model relates to a kind of main beam formula support arm frame construction of Segment gate, belongs to Hydraulic and Hydro-Power Engineering earial drainage Segment gate technical field.
Background technology
Segment gate is widely a kind of gate pattern of the current usage comparison of Hydraulic and Hydro-Power Engineering, and the obstructing surface with circular arc uses as Service gate on the hydraulic structure of being everlasting.Segment gate is comprised of gate flap, support arm and a hinge usually, and the gate main body can be around a hinge center rotating at its arc radius center.Radial gate support hinge generally is arranged in the downstream, and its elevation will be considered and not impacted by current and floating thing.Segment gate structurally requires enough intensity and integral rigidity, and good manufacturability is arranged, and makes things convenient for manufacturing, transportation, installation, anti-corrosion and maintenance, and saves as far as possible steel.Segment gate can be divided into main beam formula and main longitudinal grider formula according to the arrangement of girder.For the Segment gate of large span, generally adopt main beam two support arm type frame constructions, two rigidly connected a little about main beam and every group of support arm had.Development along with science and technology, the span of Segment gate is increasing, and by traditional gate pattern design, main beam span centre and the cantilever segment moment of flexure of Segment gate are increasing, cause the main beam sectional dimension of supporting arc shape gate increasing, thereby make Segment gate manufacturing, installation difficulty.Therefore, the main beam formula support arm frame construction of existing Segment gate or undesirable.
Summary of the invention
The purpose of this utility model is, a kind of main beam formula support arm frame construction of Segment gate is provided, and this structure can reduce main beam span centre and cantilever segment moment of flexure, and then reduces main beam sectional dimension, cost saving.
For realizing the purpose of this utility model, the main beam formula support arm frame construction of a kind of Segment gate of the present utility model comprises main beam, wherein, be arranged with the support arm framework of two " Y " type system frameworks on the described main beam, tail end and the radial gate support hinge of support arm framework are hinged.
Further, the main beam formula support arm frame construction of above-mentioned Segment gate, wherein, described support arm framework is rigidly connected two " Y " type structures that form by allotment arm and " V " type support arm closed angle end.
Further, the main beam formula support arm frame construction of above-mentioned Segment gate, wherein, described " V " type support arm openend two legs and main beam rigidly connect.
Owing to having adopted the technical solution of the utility model, make traditional " ∏ " type main beam allotment arm framework become the double-Y shaped support arm frame construction of main beam, by two " Y " type support arm frame constructions of main beam, increased the stability of structure, for the safe operation of gate provides guarantee; Count by having increased rigidly connecting of support arm and main beam, reduced main beam span centre and cantilever segment moment of flexure, and then reduce the main beam sectional dimension, cost saving is worthy to be popularized.

Description of reference numerals: 1-main beam, 2-support arm framework, 3-" V " type support arm, 4-radial gate support hinge, 5-allotment arm.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.But conduct is not to any restriction foundation of the present utility model.
See first Fig. 1 and Fig. 2, the main beam formula support arm frame construction of a kind of Segment gate of the present utility model comprises main beam 1, is arranged with the support arm framework 2 of two " Y " type system frameworks at main beam 1, and the tail end of support arm framework 2 and radial gate support hinge 4 are hinged.In addition, support arm framework 2 is rigidly connected two " Y " type structures that form by allotment arm 5 and " V " type support arm 3 closed angle ends.Described " V " type support arm 3 openends, two legs and main beam 1 rigidly connect.
The schematic diagram of the prior art that comparison diagram 3 and Fig. 4 show can be found out, owing to having adopted the technical solution of the utility model, every main beam 1 has more twice with the firm number of connections of support arm framework 2, main beam 1 rigidly connects stressed reducing a little, thereby main beam 1 span centre and cantilever segment moment of flexure are reduced, can use so less main beam 1 sectional dimension just can support its Segment gate, be convenient to manufacturing and the installation of Segment gate, also can reduce construction costs, thereby reach the purpose of this utility model.
Above-mentioned is a kind of embodiment of the present utility model, and the utility model also has other embodiment, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the desired protection domain of the utility model.
