Technical Field

The invention relates to traffic facilities, in particular to a height limiting rod.

Background

The door-shaped stop bars, namely the height-limiting bars, are arranged near various traffic facilities such as overpasses and the like to prevent the vehicle from being damaged due to the collision with the bridge opening, and the common height-limiting bars have obvious problems in use, for example, drivers of many vehicles cannot judge whether the vehicle can safely pass through when approaching the height-limiting bars, and although some height values are marked on the height-limiting bars, the accurate heights of the vehicle and a load are often difficult to know, or whether the vehicle can pass through is determined by getting-off observation or not, or the occurrence of a serious accident that the collision bars even collide with the bridge opening is caused by misjudgment, so the relatively safe height-limiting bars are very needed.

Disclosure of Invention

The object of the present invention is to provide a new solution for a height-limiting bar, which solves the aforementioned problems.

The technical scheme of the invention comprises the following steps: the road blocking device comprises a square upright post and blocking rods, wherein the left and right upright posts are respectively arranged at two sides of a road, the top end of each upright post is horizontally provided with a pin shaft, the left and right pin shafts are positioned on the same axis, the inner ends of the pin shafts are connected with a pair of lever arm combinations in a shape of a same sign, each lever arm combination comprises a shorter striker rod arm and a longer blocking rod arm, and the upper ends of the striker rod arm and the blocking rod arm are respectively and transversely connected with the striker rod and the blocking rod; a round position control disc is fixedly connected to the outer end of the right side pin shaft, a hanging rod is arranged on the position, close to the upper part and on the left side, of the position control disc, a notch is machined on the position, close to the lower part, of the position control disc, a stop lever is fixed on the stand column through the notch in the position control disc, the left side of the notch is blocked by the stop lever, the upper end of a spring is hung on the hanging rod, the lower end of the spring is hung on the stand column in an elastic tensioning mode, and the axis of the spring is located on the left side of the center of the position control disc; when a running vehicle is higher than the allowed height, namely higher than the height of the collision rod, the vehicle firstly touches the collision rod and drives the rod arm combination, the barrier rod forwards overturns for a certain angle around the pin shaft, the collision rod rotates to the highest position, the barrier rod rotates to the lowest position, namely the front position of the vehicle, clear and unsmooth interception is given to a driver, and meanwhile, the control panel synchronously rotates the same and stops at the right side of the opening to touch the barrier rod, so that the occurrence of collision accidents is effectively avoided, and one interception task is completed.

The invention has the beneficial effects that: the method can clearly display and intercept the collision accident caused by misjudgment.

Detailed Description

As shown in fig. 1, 2 and 3, the height-limiting rod of the design comprises a square upright post 1 and a blocking rod 4, wherein the left side and the right side of the upright post 1 are respectively and vertically arranged at two sides of a road, the top end of the upright post 1 is horizontally provided with a pin shaft 2, the left pin shaft and the right pin shaft are both arranged on the same axis, the inner ends of the pin shafts are connected with a pair of number-shaped rod arm combinations, each rod arm combination comprises a shorter striker arm 5 and a longer blocking rod arm 6, the upper ends of the striker arm 5 and the blocking rod arm 6 are respectively and transversely connected with the striker 3 and the blocking rod 4, the pair-shaped rod arm combination refers to that the whole combination of the shorter striker arm 5 and the longer blocking rod arm 6 is like a pair, and has the morphological characteristics of the pair, namely, the included angles between the striker arm and the horizontal line are acute angles, and the left side is short and the right side are long; a round position control disc 7 is fixedly connected to the outer end of the right pin shaft, a hanging rod 8 is arranged on the position, close to the left, of the position control disc, a notch is machined on the position, close to the lower portion of the position control disc, a stop rod 10 is fixed on the stand column 1 through the notch in the position control disc, the left side of the notch is blocked by the stop rod, the upper end of a spring 9 is hung on the hanging rod 8, the lower end of the spring is hung on the stand column in an elastic tensioning mode, and the axis of the spring is located on the left side of the center of the position control disc and is as shown in figures 1, 2 and 3; when the height of a running vehicle is higher than the allowable height, namely the height of the collision rod 3, the vehicle firstly touches the collision rod and drives the rod arm combination and the barrier rod to forwards turn a certain angle around the pin shaft, the collision rod rotates to the highest position, the barrier rod rotates to the lowest position, namely the front position of the vehicle, so that a driver can clearly intercept the vehicle which cannot pass through, as shown in figures 4, 5 and 6, and meanwhile, the control positioning disc 7 correspondingly rotates in the same way and stops at the right side of the notch to touch the barrier rod, so that the occurrence of collision accidents can be effectively avoided, and one interception task can be completed; and when the height of the vehicle is lower than the intercepting height, the vehicle can directly and smoothly pass through the device. When the height limiting rod is used again, the height limiting rod is returned to the original position.
