Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction, and specifically relates to an adjustable-height speed bump for highway safety. Background Technology
[0002] In existing highway reconstruction projects, due to the long length of the roads (e.g., sections 14-16 of the TKU highway reconstruction project in Kazakhstan, which is 102km long), the roads are often open to traffic during construction, resulting in high traffic volume and some vehicles traveling at high speeds and carrying heavy loads. Conventional construction methods rely on mobile sentries at distant locations to direct traffic, or on standard methods such as cones, water-filled barriers, and rigid speed bumps. These methods are highly subjective and lack effective control over vehicles, easily leading to accidents and posing significant safety hazards to the project. Furthermore, rigid speed bumps force vehicles to slow down, making it impossible to flexibly adjust the height according to road speed limits or vehicle type, affecting traffic efficiency and comfort. Fixed speed bumps can also impact vehicle suspension systems, potentially causing damage to vehicle components with prolonged use. Utility Model Content

The lifting unit includes at least two mounting boxes disposed within the mounting groove, a telescopic rod disposed within each mounting box, a first movable block connected to the output end of the telescopic rod, and an adjusting bracket. The adjusting bracket consists of two cross-shaped rectangular supports. The bottoms of the rectangular supports are respectively connected to the first movable blocks disposed on opposite sides, and the cross-position of the rectangular supports is connected by a fixed rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

At the same time, in conjunction with the shock absorption unit, it effectively absorbs the impact force of vehicles and reduces vibration damage to the vehicle body.
[0013] The implementation scheme of this application, by using speed bumps, can change the smoothness of the road, causing vehicles to bump or vibrate when passing over them, thereby creating psychological and physiological stimulation for the driver, prompting them to actively reduce their speed, thus playing a role in mandatory restraint, reducing safety hazards, and reducing safety accidents. At the same time, it can also replace rigid speed bumps as a permanent facility, achieving the goal of combining temporary and permanent use, reducing costs and increasing efficiency.
