Description

Technical Field

[0001] The utility model relates to the technical field of height-limiting equipment, in particular to a height-limiting frame for road safety management in municipal engineering. Background Art

[0002] There are two functions of height limit frames. One is that when there is a bridge across the highway in front of the road, the vehicles driving on it must not exceed the height of the beam of the bridge. The other is to protect the road or bridge ahead by adopting a height limit method to prohibit large and overweight vehicles from driving. The common structure of height limit frames is generally in the shape of a gate, consisting of two columns and a height limit beam on the top. When an over-height vehicle forces its way through, it will hit the height limit beam on the top, thereby restricting the passage of the over-height vehicle.

[0003] The existing height limit frames used for road safety management in municipal engineering projects have some disadvantages. First, it is not easy to adjust the height and is not very practical. Second, it does not have a buffering and protective effect. There is no buffering when a vehicle is hit, which can easily cause damage to the vehicle. Third, it does not save electricity and easily causes a waste of resources. Utility Model Content

[0012] Compared with the prior art, the utility model has the following beneficial effects: easy to adjust the height, has a buffering protection function, and saves power consumption;

[0013] (1) Driven by the motor, the lead screw rotates, which in turn drives the threaded seat to rise and fall in the vertical direction along the lead screw, driving the connecting bar to rise and fall, thereby driving the connecting rod to rise and fall through the support rod, thereby driving the support to rise and fall, and limiting the height of the vehicle. Under the control of the control panel, the operation of the motor is adjusted, and the connecting bar drives the marking bar to rise and fall. The marking bar can mark clear scales on the scale, making it easy to adjust the height.

[0014] (2) The reflective tape can reflect the light of the vehicle and is used to remind the height of the support plate to avoid accidental collision with vehicles that are too high. When the support plate is about to be hit, it will first squeeze the connecting plate at the bottom of the support bar. The rubber pad on the connecting plate is a flexible material and can protect the vehicle and the height limit frame. When a vehicle that exceeds the height of the support plate collides with the support bar or the connecting plate, it squeezes the slide bar and then the spring. Since the spring is elastic, it can play a role of buffering protection. The inside of the support plate can limit the limit block, which is conducive to the stable movement of the slide bar and has a buffering protection effect.

[0015] (3) The external protective cover of the battery can support and connect the solar panel and the roof. The solar panel can convert solar energy into electrical energy, which is then stored in the battery and used to power the motor. In this way, renewable energy can be rationally utilized and electricity consumption can be saved. BRIEF DESCRIPTION OF THE DRAWINGS
