Adopt the utility model discloses a cross arm is fixed to the structure, and the installation is simple, and fixed firm, difficult pine takes off, guarantees the anti -wind ability and the stability of rack. But wide application in solar photovoltaic support field.
Description
Technical field
The utility model relates to solar photovoltaic bracket field, especially relates to the syndeton of a kind of solar photovoltaic bracket main shaft and cross-arm.
Background technology
Solar photovoltaic bracket comprises main shaft and is arranged on the rack on main shaft, and described rack comprises one group of cross-arm that is vertical with main shaft and that be fixed on main shaft, and cross-arm is fixedly installed the purlin with main axis parallel.Because rack area is large, the windage be subject to can increase along with the increase of area, and be just fixed on a main shaft by cross-arm, therefore, just require cross-arm and main shaft fixed, prevent from being subject to wind-force effect and rack being rocked on main shaft, namely impact is arranged on the thermal energy efficiency of the photovoltaic module on rack, meanwhile, also very easily cause the damage of rack, reduce the useful life of photovoltaic bracket.Traditional fixed structure is directly placed on main shaft by cross-arm, then both are tightened with fixed strip or band by one, because main shaft is round tube, and cross-arm many employings rhs-structure, a face of square tube is pressed on pipe, very easily slide, under the long term of wind-force, make to occur between cross-arm and main shaft to loosen.
Utility model content
The purpose of this utility model is to provide the syndeton of a kind of solar photovoltaic bracket main shaft and cross-arm, and the syndeton solving existing solar photovoltaic bracket main shaft and cross-arm easily loosens, and causes the problem that solar photovoltaic bracket shaking volume is large.
The utility model solves the technical scheme that its technical problem adopts: the syndeton of a kind of solar photovoltaic bracket main shaft and cross-arm, comprises the fixing briquetting be arranged between main shaft and cross-arm and the anchor ear embracing main shaft; Described fixing briquetting comprises bottom surface and is arranged on the vertical flange of both sides, bottom surface, and vertical flange is provided with the arc groove suitable with main shaft, and arc groove is pressed on main shaft, and described bottom surface is the planar structure suitable with cross-arm; Described bottom surface is also provided with the installing hole passed for anchor ear, described cross-arm is also provided with the fixing hole passed for anchor ear, described anchor ear is U-shaped structure, the two ends of anchor ear is threaded rod structure, and is fixedly connected with cross-arm by nut.
For improving anchor ear to the thrust of main shaft, described anchor ear is circular rod-shaped configuration.
For improving installation effectiveness and accuracy, described bottom surface being also provided with alignment pin, described main shaft is provided with the location hole suitable with alignment pin.
The beneficial effects of the utility model: the utility model by arranging fixing briquetting between main shaft and cross-arm, and coordinated with cross-arm by the bottom surface of compact heap, plane and plane contact, stability is better.Coordinated with main shaft by the arc groove on vertical flange, arc groove is stuck on main shaft, increase fixing contact area between briquetting and main shaft, finally, tightened by the hold-down nut on anchor ear, cross-arm is fixed on main shaft firmly, overcomes cross-arm planar structure and main shaft arc surface structure and compress the problem easily loosened.Meanwhile, anchor ear adopts circular rod-shaped configuration, makes anchor ear larger to the enclasping force of main shaft, more firmly.Described alignment pin can realize quick and precisely installing, and meanwhile, also can prevent moving axially of main shaft to a certain extent.
Below with reference to drawings and Examples, the utility model is described in detail.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the partial enlarged drawing of A in convex 1.
Fig. 3 is the structural representation fixing briquetting in the utility model.
Embodiment
Embodiment, as shown in Figures 1 to 3, the syndeton of a kind of solar photovoltaic bracket main shaft and cross-arm, comprises the fixing briquetting 1 be arranged between main shaft 3 and cross-arm 4 and the anchor ear 2 embracing main shaft.Described fixing briquetting 1 comprises bottom surface 11 and is arranged on the vertical flange 12 of both sides, bottom surface, and vertical flange 12 is provided with the arc groove 13 suitable with main shaft, and arc groove 13 is pressed on main shaft, and described bottom surface 11 is the planar structure suitable with cross-arm 4.Described bottom surface 11 is also provided with the installing hole 14 passed for anchor ear 2, described cross-arm is also provided with the fixing hole passed for anchor ear, described anchor ear 2 is U-shaped structure, the two ends of anchor ear 2 is threaded rod structure, and is fixedly connected with cross-arm by nut.
For increasing the enclasping force of anchor ear 2 pairs of main shafts 3, described anchor ear 2 is circular rod-shaped configuration, and circular rod-shaped configuration bends to suitable U-shaped with main shaft 3, and main shaft 3 is stuck in U-shaped structure.
For convenience of installing, and preventing main shaft 3 from moving axially, described bottom surface 11 being also provided with alignment pin 15, described main shaft is provided with the location hole suitable with alignment pin 15.
During installation, first fixing briquetting is inserted the location hole internal fixtion of main shaft by alignment pin, then by cross-arm frame on fixing briquetting, after fixing hole anchor ear being passed fixing briquetting installing hole and cross-arm from major axes orientation, fixing hole is stretched out at the two ends of anchor ear, and by nut screwing clamping, realize fixing of cross-arm and main shaft.This structural stability is good, not easily gets loose, and wind loading rating is strong.
