Abstract
The utility model discloses a main longitudinal beam type support arm frame structure for an radial gate, which comprises a main longitudinal beam, wherein a support arm frame formed by a large V-shaped support arm and two small V-shaped support arms is arranged on the main longitudinal beam; the sharp point end of the large V-shaped support arm is hinged with an auxiliary hinge of the radial gate; the support arm frame is in rigid connection with the main longitudinal beam; and the large V-shaped support arm is in rigid connection with the small V-shaped support arms. In addition, rigid connection positions for the support arm frame and the main longitudinal beam are on two support legs at the open ends of the small V-shaped support arms. Due to the adoption of the technical scheme disclosed by the utility model as well as increase of rigid connection points for the support arms and the main longitudinal beam, the mid-span of the main longitudinal beam and the bending moment of the suspension support arm section are reduced, the cross section size of the main longitudinal beam is further reduced, and the project investment is saved.
Description
Technical field
The utility model relates to a kind of main longitudinal grider formula support arm frame construction of arc door, belongs to Hydraulic and Hydro-Power Engineering earial drainage arc gate technique 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.The arc door props up hinge and 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 narrow hole of height arc door, generally adopt main longitudinal grider " V " support arm type frame construction, main longitudinal grider and support arm have two to rigidly connect a little.But along with the development of science and technology, the arc door is highly more and more higher, and by traditional gate pattern design, main longitudinal grider span centre and cantilever segment moment of flexure are increasing, cause the main longitudinal grider sectional dimension increasing, not only make the gate manufacturing, difficulty is installed, and it is too much to expend steel.Therefore, the main longitudinal grider formula support arm frame construction of existing arc door or undesirable.
Summary of the invention
The purpose of this utility model is, a kind of main longitudinal grider formula support arm frame construction of arc door is provided, and this structure can reduce main longitudinal grider span centre and cantilever segment moment of flexure, and then reduces main longitudinal grider sectional dimension, cost saving.
For realizing the purpose of this utility model, the main longitudinal grider formula support arm frame construction of a kind of arc door of the present utility model, comprise main longitudinal grider, wherein, described main longitudinal grider is provided with by large " V " type support arm and two support arm frameworks that little " V " type support arm forms, and it is hinged that the closed angle end of large " V " type support arm and arc door prop up hinge.
Further, the main longitudinal grider formula support arm frame construction of above-mentioned arc door, wherein, described support arm framework and main longitudinal grider rigidly connect, and described large " V " type support arm and little " V " type support arm rigidly connect.
Further, the main longitudinal grider formula support arm frame construction of above-mentioned arc door, wherein, the position that described support arm framework and main longitudinal grider rigidly connect is at little " V " type support arm openend two legs.
Owing to having adopted the technical solution of the utility model, make traditional main longitudinal grider " V " type support arm framework become two " Y " type support arm frame constructions of main longitudinal grider, increase the firm number of connections of main longitudinal grider and support arm, main longitudinal grider span centre and cantilever segment moment of flexure have been reduced, and then minimizing main longitudinal grider sectional dimension, cost saving is worthy to be popularized.

Description of reference numerals: the 1-main longitudinal grider, large " V " type support arm of 2-, 3-little " V " type support arm, 4-arc door props up hinge.
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 longitudinal grider formula support arm frame construction of a kind of arc door of the present utility model, comprise main longitudinal grider 1, main longitudinal grider 1 is provided with by large " V " type support arm 2 and two support arm frameworks that little " V " type support arm 3 forms, and the position that support arm framework and main longitudinal grider 1 rigidly connect is at little " V " type support arm 3 openends two legs.It is hinged that the closed angle end of " V " type support arm 2 and arc door prop up hinge 4 greatly.Support arm framework and main longitudinal grider 1 rigidly connect, and described large " V " type support arm 2 rigidly connects with little " V " type support arm 3.
See Fig. 3 and Fig. 4, Fig. 3 and Fig. 4 are the prior art schematic diagrames of the main longitudinal grider formula support arm frame construction of arc door, structure from figure and Structure Comparison of the present utility model can be known, owing to having adopted the technical solution of the utility model, the firm number of connections of main longitudinal grider and support arm has increased twice, reduce main longitudinal grider span centre and cantilever segment moment of flexure, and then reduced main longitudinal grider sectional dimension, cost saving.
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.
