[0002] The existing highways will generally be set at an interval of a portal, the first is used for arranging speed limit probe to shoot overspeed, the second is used for arranging LED electronic display screen to provide information prompt for passing drivers, and the third is used for arranging ETC billing equipment. The portal in the prior art mainly comprises a column, a beam, a connecting beam, a flange and the like, the column is erected on both sides of the highway, the beam is installed between the two columns through the flange, and the connecting beam is arranged between the two beams to support the beams and also to install equipment to monitor and prompt vehicles on the highway.

[0003] At present, the column flange and the beam flange of the portal product are basically connected by horizontal bolts. Such a connection mode has high construction requirements and is complicated in later maintenance. When the flanges are connected and installed in the horizontal direction, the installation position has high requirements, and after the bolt holes of the beam and the flange are aligned by using a traction device, fastening is performed. The flange needs to be adjusted multiple times in the process. When this installation mode is used in a high-speed road section, the installation time is long, which affects ground traffic. Therefore, the installation efficiency needs to be further improved. In view of this, the present application is proposed. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a portal with inclined column flange and beam connection which can overcome the above problems or at least partially solve the above problems.

[0005] To solve the above technical problems, the basic idea of the technical scheme adopted by the present application is as follows: a portal with inclined column flange and beam connection, comprising a portal column, a bottom plate, a portal beam and a portal connecting beam, the bottom plate is welded at the bottom of the portal column and used for connecting and fixing with the ground, the portal column is symmetrically provided with two groups, the portal beam is connected between each group of two portal columns, the portal connecting beam is symmetrically connected between the two portal beams, further comprising: a connecting column which is transversely penetrated through the upper side of the portal column and welded between the portal column; a column flange disc which is fixedly connected at one end of the two connecting columns close to each other; a beam flange disc which is symmetrically and obliquely connected at both ends of the portal beam and has an oblique angle matching the oblique angle of the column flange disc; and the column flange disc and the beam flange disc are fixedly connected by a fixing bolt.

[0006] To facilitate flexible adjustment of the position of the crossbeam flange disc according to the distance between the gantry columns, a connecting steel pipe is further fixedly connected laterally to the side of the crossbeam flange disc closest to the gantry crossbeam, and threaded columns are symmetrically fixedly connected to both ends of the gantry crossbeam. The threaded columns are rotatably connected to the connecting steel pipe by threads, and the diameters of the gantry crossbeam and the threaded columns are the same as the inner diameter of the connecting steel pipe.

[0007] To prevent misalignment of the two crossbeam flange discs during position adjustment, which could lead to misalignment when connecting them to the column flange discs due to angular deviation, a connecting plate is fixedly connected to the lower side of the two connecting steel pipes at their closest points. A limiting sleeve is provided between the two connecting plates, and limiting rods are symmetrically slidably connected inside the limiting sleeve. The ends of the two limiting rods at their furthest points are fixedly connected to the adjacent connecting plates.

[0008] To facilitate the rotation of the gantry beam by workers and prevent slippage of their hands or tools on the surface of the gantry beam, anti-slip rings are symmetrically fixedly connected to both sides of the surface of the gantry beam.

[0009] To further improve the overall stability of the gantry, the connecting column and the upright flange disc, the crossbeam flange disc and the connecting steel pipe, the gantry crossbeam and the threaded column, the connecting steel pipe and the connecting plate, and the connecting plate and the limit rod are respectively welded and fixed by a welding machine.

[0010] To facilitate quick assembly and disassembly of the gantry connecting beam, the end face of the gantry connecting beam is designed with an inner arc surface. The end of the gantry connecting beam is tightly attached to the adjacent connecting steel pipe through the inner arc surface. The end of the gantry connecting beam is symmetrically connected to an arc-shaped clamping plate through a pivot axis. The two arc-shaped clamping plates are tightly clamped to the connecting steel pipe by connecting bolts.

[0011] To facilitate flexible adjustment of the spacing between the two gantry connecting beams, thus adapting to gantry widths of different specifications, multiple connecting sleeves are provided at equal intervals between the two gantry connecting beams. Two connecting rods are symmetrically slidably connected to both sides of each connecting sleeve, and the ends of the two connecting rods that are far apart from each other are respectively fixedly connected to the adjacent gantry connecting beams.

[0012] To facilitate the limiting function of the two gantry connecting beams and make them more stable during transport, the outermost connecting sleeve and its matching connecting rod are further connected by a threaded rotation.

[0013] In order to facilitate the anti-skid effect on the hands of the staff or the rotating tool, so as to facilitate the staff to rotate the connecting sleeve more stably, further, the outermost surface of the connecting sleeve is fixedly connected with an anti-skid ring.

[0014] In order to facilitate the rainproof effect of the column flange disc and the beam flange disc, and avoid the rainwater rusting of the fixing bolts between the column flange disc and the beam flange disc, further, the top of the gantry column is fixedly connected with a rainproof shed on one side close to the gantry beam, and the rainproof shed is sleeved outside the column flange disc and the beam flange disc.

[0015] Compared with the prior art, the present application has the following beneficial effects: by connecting the column flange disc and the beam flange disc with an inclined surface, the gravitational force of the gantry beam can be utilized to generate a friction force between the column flange disc and the beam flange disc and an inclined upward supporting force on the gantry beam, so that the connection between the column flange disc and the beam flange disc is more stable, and the stability of the connection between the gantry column and the gantry beam is ensured; at the same time, the position of the beam flange disc can be quickly adjusted, so that the installation process is more convenient and fast; the connection between the gantry column and the gantry beam is also more beautiful, and when it rains, the inclined column flange disc and the beam flange disc are not easy to accumulate water, and the water flow can be quickly drained along the inclined surface, so that the service life and stability are greatly improved.
