[0033] Embodiment 1
[0034] As Figures 1 to 10As shown in the figure, a highway bridge traffic restriction device provided in this embodiment includes two symmetrically arranged support columns 10. A telescopic cross bar 20 is connected between the tops of the two support columns 10. The cross bar 20 is used to adjust the distance between the two support columns 10. Longitudinal chutes 11 are provided on the inner side walls of the two support columns 10 facing each other. A lead screw 12 and a slider 13 threadedly connected to the lead screw 12 are provided in each of the two chutes 11. One side of each of the two sliders 13 away from the support column 10 is rotatably connected to a traffic restriction cross bar 30. The two traffic restriction cross bars 30 are symmetrically arranged. The lead screw 12 is used to drive the slider 13 to slide up and down in the chute 11 to drive the traffic restriction cross bar 30 to move up and down. The traffic restriction cross bar 30 is used to adjust the passing height of the traffic restriction device. A number of traffic restriction slots 31 with axes parallel to the axis of the traffic restriction cross bar 30 are provided at the bottom of the traffic restriction cross bar 30. A slide bar 32 is slidably provided in the traffic restriction slot 31. A number of traffic restriction vertical bars 33 are equidistantly connected to the slide bar 32. The number of traffic restriction vertical bars 33 is used to adjust the passing width of the traffic restriction device.
[0035] Specifically, in this embodiment, a relatively wide support base 14 is provided at the bottom of the support column 10 to improve the stability of the support column 10 through the support base 14. The overall highway bridge traffic restriction device provided in this application is a symmetric structure. A telescopic cross bar 20 is provided at the tops of the two support columns 10. The traffic restriction width between the two support columns 10 can be adjusted according to actual site needs through the cross bar 20. A chute 11 is provided on the inner side wall of the support column 10. The chute 11 is provided with a lead screw 12 and a slider 13 threadedly connected to the lead screw 12. One side of the slider 13 is rotatably connected to a traffic restriction cross bar 30. By rotating the lead screw 12, the slider 13 is driven to move up and down, and then the traffic restriction cross bar 30 rotatably connected to the slider 13 is driven to move up and down, thereby adjusting the traffic restriction height. It can be understood that the purpose of restricting over-limit motor vehicles can be achieved through the traffic restriction cross bar 30 and the telescopic cross bar 20. At this time, there is no need to provide a slide bar 32 and traffic restriction vertical bars 33; the traffic restriction cross bar 30 is rotatably connected to the slider 13 in the horizontal plane. When some over-limit vehicles collide with the traffic restriction device, the traffic restriction cross bar 30 can rotate in the horizontal plane to prevent damage caused by hard contact with the over-limit vehicles.
[0036] Furthermore, a number of slide bars 32 are provided at the bottom of the traffic restriction cross bar 30. In this embodiment, two slide bars 32 are provided at the bottom of each traffic restriction cross bar 30. Traffic restriction vertical bars 33 are equidistantly provided on the slide bars 32; when the bridge is under renovation or other stages and it is necessary to prohibit motor vehicles from passing but allow two-wheeled electric vehicles to pass, first connect the traffic restriction vertical bars 33 equidistantly to the slide bars 32, rotate the traffic restriction cross bar 30, and connect the slide bars 32 in the traffic restriction slot 31 at the bottom of the traffic restriction cross bar 30, as Figure 9As shown in the figure, the two sliding rods 32 at the bottom of the traffic restriction crossbar 30 are parallel, and the traffic restriction vertical rods on the two sliding rods 32 are arranged in parallel. The traffic restriction width of the bridge is reduced by the traffic restriction vertical rods 33 arranged at equal intervals, allowing two-wheeled vehicles and pedestrians to pass through. Further, when it is necessary to completely prohibit vehicle passage and only allow pedestrians to pass, the sliding rods 32 can be slid, as shown in Figure 10 As shown in the figure, the two sliding rods 32 at the bottom of the traffic restriction crossbar 30 are staggered, and the traffic restriction vertical rods on the two sliding rods 32 are arranged in a staggered manner, further reducing the traffic restriction width of the bridge and only allowing pedestrians to pass through.
[0037] Optionally, the crossbar 20 includes two symmetrically arranged fixed rods 21 and a push rod 22 arranged between the two fixed rods 21. The two ends of the push rod 22 are inserted into the two fixed rods 21 and are slidably connected to the fixed rods 21. The end of the fixed rod 21 away from the push rod 22 is fixedly connected to the support column 10.
[0038] Optionally, a threaded hole 131 threadedly connected to the lead screw 12 is provided through the slider 13. A driving motor 121 is provided at the top of the lead screw 12. The driving motor 121 is used to drive the lead screw 12 to rotate so as to drive the slider 13 to move up and down. The slider 13 is threadedly and rotationally connected to the lead screw 12. When the driving motor 121 drives the lead screw 12 to rotate, the slider 13 moves up and down.
[0039] Further, a first connecting plate 132 is provided on one side of the slider 13 close to the traffic restriction crossbar 30, and a second connecting plate 34 is provided on one side of the traffic restriction crossbar 30 close to the slider 13. The first connecting plate 132 and the second connecting plate 34 are rotatably connected through a rotating shaft 133. Optionally, in this embodiment, the first connecting plate 132 is above the second connecting plate 34. Coaxial connecting holes are provided on both the first connecting plate 132 and the second connecting plate 34. The first connecting plate 132 and the second connecting plate 34 are partially staggered to form a receiving groove 341 between the first connecting plate 132 and the second connecting plate 34. A return spring 342 is provided in the receiving groove 341. When the traffic restriction crossbar 30 is tilted after being collided by an over-limit vehicle, it can be reset by the return spring 342.
[0040] Optionally, in this embodiment, a plurality of through holes 321 are arranged at equal intervals on the sliding rod 32, and a limiting protrusion 331 is provided at one end of the traffic restriction vertical rod 33. When the traffic restriction vertical rod 33 is inserted through the through hole 321, the limiting protrusion 331 can prevent the traffic restriction vertical rod from falling off. In this embodiment, the depth of the traffic restriction groove 31 is greater than the height of the sliding rod 32; further, limiting holes 35 with axes perpendicular to the axis of the traffic restriction cross bar 30 are provided at the ends of the two traffic restriction cross bars 30 close to each other, and a limiting groove 322 corresponding to the limiting hole 35 is provided on the side wall of the sliding rod 32. The sliding rod 32 is connected to the traffic restriction groove 31 through a pin 323 that sequentially passes through the limiting hole 35 and the limiting groove 322. Through the pin 323, the position of the sliding rod 32 in the traffic restriction groove 31 can be limited, preventing the sliding rod 32 from moving freely in the traffic restriction groove 31.
[0041] Optionally, in this embodiment, a weight reduction groove 36 is provided at the top of the traffic restriction cross bar 30, and a reinforcing rod 37 is provided between the side walls in the weight reduction groove 36. By providing the weight reduction groove 36, the weight of the traffic restriction cross bar 30 can be reduced, and by providing the reinforcing rod 37, the strength of the traffic restriction cross bar 30 can be increased. Further, a connecting groove 38 is provided above the ends of the two traffic restriction cross bars 30 close to each other, and the two traffic restriction cross bars 30 are connected through a connecting member 39 provided in the connecting groove 38. By providing the connecting member 39, the sag of the traffic restriction cross bar 30 caused by gravity can be reduced. Still further, warning strips 40 are arranged on the front and rear side walls of the traffic restriction cross bar 30, and the warning strips 40 are made of a reflective material. Through the reflective characteristic of the warning strips 40, a good warning effect can also be achieved at night, reminding the driver to be vigilant and there is a traffic restriction ahead.
[0042] In summary, the highway bridge traffic restriction device provided by the present utility model can be applicable to various on-site situations. Specifically, when the bridge is fully open to traffic, on the one hand, the retractable crossbar 20 can be used to adjust the traffic width; on the other hand, by rotating the traffic restriction crossbar 30 to be parallel to the traffic direction, the traffic height restriction can be lifted. When the bridge has width and height restrictions, the retractable crossbar 20 can be used to adjust the traffic restriction width of the bridge. By rotating the traffic restriction crossbar 30 to be perpendicular to the traffic direction and driving the traffic restriction crossbar 30 to move up and down by rotating the lead screw 12, the traffic restriction height of the bridge can be adjusted. When the bridge restricts motor vehicle traffic, by arranging slide bars 32 at the bottom of the traffic restriction crossbar 30 and connecting traffic restriction vertical bars 33 to the slide bars 32, the traffic restriction width of the bridge can be reduced by the equally spaced traffic restriction vertical bars 33, allowing two-wheeled vehicles and pedestrians to pass. When it is necessary to completely prohibit vehicle traffic and only allow pedestrians to pass, the slide bars 32 can be slid, and the two slide bars 32 at the bottom of the traffic restriction crossbar 30 are staggered, and the traffic restriction vertical bars on the two slide bars are arranged alternately, further reducing the traffic restriction width of the bridge and only allowing pedestrians to pass. The highway bridge traffic restriction device provided by this application has adjustable traffic restriction width and traffic restriction height, and can adjust traffic according to the renovation situation of the bridge. It has strong versatility. The traffic restriction crossbar 30 can rotate in a plane to prevent damage when being collided, and is suitable for wide promotion.
[0043] It should be noted that the above implementation process is only to illustrate the feasibility of this application, but this does not mean that the highway bridge traffic restriction device of this application only has the above implementation process. On the contrary, as long as the highway bridge traffic restriction device of this application can be implemented, it can be included in the feasible implementation solutions of this application.
