Abstract
The utility model discloses a main beam type support arm frame for a radial gate, which adopts the structure that a support arm frame formed by two symmetrical right triangle-shaped frames is arranged on a main beam, and the tail ends of the support arm frame are hinged with auxiliary hinges of the radial gate. In addition, the two symmetrical right triangle-shaped frames are formed by two straight support arms, one V-shaped support arm and two straight hook type support arms through rigid connection. The straight hook type support arms and the sharp point end of the V-shaped support arm are in rigid connection with the main beam, and two support legs at open ends of the V-shaped support arm are in rigid connection with the two straight hook type support arms, at positions of the hook ends. According to the main beam type support arm frame for the radial gate, two large triangular structures are formed by the main beam and the support arms, therefore, the structural stability is enhanced and safe operation of a gate is ensured; and moreover, as the rigid connection points of the support arms and the main beam are increased, the mid-span of the main beam and the bending moment of the suspension support arm section are reduced, the cross section size of the main beam is further reduced, and the project investment is saved.
Description
Technical field
The utility model relates to a kind of main beam formula support arm framework 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 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 framework of arc door 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 framework of a kind of arc door of the present utility model comprises main beam, wherein, described main beam is provided with the support arm framework by the right-angled triangle system framework of two symmetries, and it is hinged that the tail end of support arm framework and arc door prop up hinge.
Further, the main beam formula support arm framework of above-mentioned arc door, wherein, the right-angled triangle framework of described two symmetries is rigidly connected by two allotment arms, " V " type support arm and two straight hook support arms and forms.
Further, the main beam formula support arm framework of above-mentioned arc door, wherein, described straight hook support arm and " V " type support arm closed angle end and main beam rigidly connect; Described " V " type support arm openend two legs and two straight hook support arms rigidly connect.
Further, the main beam formula support arm framework of above-mentioned arc door, wherein, described " V " type support arm openend two legs and two straight hook support arms rigidly connect the position in the cheicers termination of straight hook support arm.
Owing to adopted the technical solution of the utility model, made traditional " ∏ " type main beam allotment arm framework become the two triangular form support arm frame constructions of main beam.Consist of two large triangular structures by main beam and support arm, 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 main beam sectional dimension, cost saving.

Description of reference numerals: the 1-main beam, 2-support arm framework, 3-allotment arm, 4-" V " type support arm, the straight hook support arm of 5-, 6-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 the main beam formula support arm framework of Fig. 2 a kind of arc door of the present utility model, comprise main beam 1, wherein be provided with support arm framework 2 by the right-angled triangle system framework of two symmetries at main beam 1, it is hinged that the tail end of support arm framework 2 and arc door prop up hinge 6.See Fig. 1, the right angle trigonometry framework of two symmetries is rigidly connected by two allotment arms 3, " V " type support arm 4 and two straight hook support arms 5 and forms.Straight hook support arm 5 and " V " type support arm 4 closed angle ends and main beam 1 rigidly connect; Described " V " type support arm 4 openends, two legs and two straight hook support arms 5 rigidly connect." V " type support arm 4 openends, two legs and two straight hook support arms 5 rigidly connect the position in the cheicers termination of straight hook support arm 5.
Because the utility model in terms of existing technologies, the firm number of connections of every main beam and support arm framework is many, main beam rigidly connects stressed reducing a little, thereby main beam span centre and cantilever segment moment of flexure are reduced, can use so less main beam 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.
