The utility model aims at providing a novel crossbeam connecting device of fixed grid bar grid, the modern design does not have the secondary welding when the installation, can not lead to grid deformation, and it crosses the water area and is the biggest, and reduces the floater and hang on the grid bar, and practicality is excellent.
The utility model discloses a solve the technical scheme that its technical problem adopted and be:
a novel fixed grid bar grid's crossbeam is connected device includes:
a grid; the front side of the grating is arranged to be the upstream side, the back side of the grating is fixedly provided with connecting pieces, the laths of the connecting pieces and the grating bars of the grating are welded into a whole in a one-to-one correspondence manner, and the bottom of the end surface of each connecting piece is welded with a transverse plate;
a beam: the cross beam comprises a circular tube, two ends of the circular tube are provided with bases, and the circular tube is connected with the supporting plate through a supporting rod arranged above the circular tube;
the fixing screw holes formed in the surfaces of the cross beams correspond to the fastening screw holes formed in the surfaces of the supporting plates, the fixing screw holes and the fastening screw holes correspondingly form butt joint screw holes, and screws are installed in the butt joint screw holes to fix the cross beams and the grids.
Furthermore, the laths and the grate bars are vertically fixed, and the thickness of the laths is equal to that of the grate bars.
Furthermore, the base and the round pipe are detachably connected, and the base is trapezoidal.
Furthermore, the round pipe, the supporting rod and the supporting plate are integrated in a welding mode.
Further, the connecting piece has all seted up the breach groove in fixed screw position.
Further, the width of the transverse plate is the same as that of the supporting plate.
The utility model has the advantages that:
to sum up, the utility model relates to a rationally, through replenishing the connecting piece between grid and the crossbeam, connecting piece and grid integrated into one piece processing, during the installation with the bolt fastening of crossbeam, no secondary welding leads to the grid to deform when can guaranteeing the installation, after the installation, it crosses the water area the biggest, and reduces the floater and hang on the grid, practicality is excellent, can be applied to the sewage treatment field.
