The invention relates to a municipal road intersection height and load limiting device which comprises a supporting rod, a sliding rod extending in the driving direction is fixed to the supporting rod, a height limiting beam is arranged on the sliding rod in a sliding mode, a control groove is formed in the supporting rod, a control block is arranged in the control groove in a sliding mode, a pulling assembly is connected with the control block, the pulling assembly is connected with the control block and the height limiting beam, a plurality of switch grooves are formed in the groove walls of the control groove respectively, the heights of the switch grooves are different, switch pieces triggered through the control block are arranged in the switch grooves in a sliding mode, triggering mechanisms triggered through the switch pieces are arranged in the switch grooves respectively, the side, close to the sliding rod, of the supporting rod is provided with an early-warning deceleration blocking mechanism controlled through a triggering mechanism. The device has the effect of reducing damage to vehicles and height limiting frames.
Description
technical field [0001] The present application relates to the field of height-limiting and load-limiting devices, in particular to a height-limiting and load-limiting device for municipal road intersections. Background technique [0002] The height limit and load limit device is a portal frame structure used at the entrance of bridges and tunnels to protect bridges and tunnels and prevent super-high and overweight vehicles from passing through bridges and tunnels. [0003] In the related art, the Chinese patent whose notification number is CN211171716U discloses a kind of limit elevated road bridge, which comprises a left column, a right column, an upper push rod, a moving rod, a left fixing part, a right fixing part, the bottom of the left column and the right column The bottom plate is welded, and the four corners of the bottom plate are provided with round holes. After the fixing bolts are connected with the round holes, the bottom plate is fixed on the ground. The left c...
