Problems solved by technology
[0005] The problem to be solved by the present invention is to provide a protective width limiting device used in municipal engineering to overcome the purpose of limiting the width of the vehicle when the vehicle is fast or slow after the width of the width limiting device in the prior art is set. If a fast-moving vehicle hits the width limiting device, it will receive a great impact, which will cause great personal injury to the driver and passengers in the vehicle

Embodiment Construction
[0058] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0059] Such as figure 1 , 2 , 3, it includes a fixed shell 1, a trigger mechanism 2, a width-limiting column mechanism 3, an energy storage mechanism 4, a square groove 5, a first accommodating cavity 6, a second accommodating cavity 7, such as Figure 4 , 5 As shown, the fixed shell 1 is provided with a plurality of square grooves 5 for installing the trigger mechanism 2, and each square groove 5 is installed with the trigger mechanism 2; Figure 4 As shown, the fixed shell 1 is also provided with a first accommodating cavity 6 for installing the energy storage mechanism 4 and a second accommodating cavity 7 for installing two symmetrically distributed width limiting column mechanisms 3, and the first accommodati...

The invention belongs to the technical field of width-limiting devices, and in particular relates to a protective width-limiting device for municipal engineering. The protective width-limiting devicefor municipal engineering comprises a fixed shell, a triggering mechanism and the like. The width-limiting device is provided with the triggering mechanism. A Newton fluid device for recognizing a vehicle speed is arranged in the triggering mechanism, a fast moving vehicle enables the Newton fluid device in the triggering mechanism to move and drives a rack and a gear in the triggering mechanism connected thereto to move, two width-limiting column mechanisms become slim and high from an initial state of being short and fat, the distance between the two width-limiting column mechanisms become wide from an initial state of being narrow, and the fast moving vehicle passes safely; and a slowly moving vehicle enables the Newton fluid structure in the triggering mechanism to deform, the Newton fluid structure no longer drives a moving bar to move, the triggering mechanism no longer works and an energy storage mechanism no longer works, and the two width-limiting column mechanisms will be kept in the initial state of being short and fat, so that the purpose that vehicles in a special width range pass is achieved.
Description
Technical field [0001] The invention belongs to the technical field of width limiting devices, and in particular relates to a protective width limiting device used in municipal engineering. Background technique [0002] At present, the existing width-limiting devices mostly use cement-poured piers or plastic buckets filled with water, set a certain width and place them on the road surface. When vehicles pass by, they can limit the width of passing vehicles; but when the driver is in When driving at night, the warning bar on the width-limiting pier will lose its warning effect after prolonged exposure to the sun, which makes it very easy for the car to hit the width-limiting pier, and the speed will quickly crash into the width-limiting pier set on the road. , It will cause great bodily harm to the driver and passengers in the car; at the same time, even if the warning strip has a warning effect, the driver will feel tired after driving for a long time or the driver will not see t...
