1.Our Company

Qingdao Taicheng Transportation Facilities Co., Ltd. is a technological innovation enterprise invested by Henger Group. Its headquarters is located in Jinkou Industrial Park, Qingdao. Taicheng Transportation has an innovative scientific research team, advanced manufacturing technology, first-class production facilities, and perfect testing methods. , reliable product quality, enthusiastic after-sales service, devoted to the great cause of improving China's road safety.

The impact-resistant and energy-absorbing rotating guardrail independently developed and designed by Taicheng Transportation has broken the technological monopoly of Korean and American countries and filled the market gap of China's rotating guardrail. The product has more than 20 national patents, and has successfully passed the collision test of small cars (family cars), buses and large trucks in the highway test site of the Ministry of Communications, and the test results and collision data are at the international leading level.

The new series of rotating anti-collision barriers have been widely used in South Korea, Japan, the United States, the United Arab Emirates and other countries. The accident rate, economic loss rate and accident fatality rate of the installed road section have been reduced by more than 95%, which has greatly protected the lives of pedestrians. Property safety provides a reliable guarantee and strong shield for road safety. It is believed that in the near future, the new type of rotating anti-collision guardrail will be popularized on China's highways and accident-prone sections, introducing innovative protection design for China's road environment, bringing leap-forward protection effects for road safety, and becoming a life project for the benefit of future generations. .

The company will always adhere to the corporate tenet of "not forgetting the original intention, people-oriented, and technological innovation", to build a first-class transportation facility enterprise with international competitiveness, to provide the society with high-quality new rotating anti-collision guardrails, and to protect the road safety of the country and the world. convoy.

3.Product description

The rotating guardrail adopts the "one column and four columns" method. By strengthening the performance and installation method of the columns and guardrails, it can effectively prevent cars from passing through the guardrail and driving out of the driving lane. It pioneered the use of a rotating structure to support the elastic, anti-collision and wear-resistant rotating barrel on the column, so that the rotating barrel can rotate freely on the column. This free rotation of the rotating barrel decomposes the impact force of the car. In this way, the impact force perpendicular to the direction of the guardrail is decomposed into the direction parallel to the guardrail, and is effectively absorbed and reduced by the rotating barrel, thereby effectively reducing the consequences of traffic accidents.

4.The functions of rotating anti-collision guardrail

When a car is about to collide and rush towards the guardrail, due to the rotation of the roller, the impact energy of the car is converted into rotational energy parallel to the guardrail, achieving the effect of overcoming rigidity with softness. As a longitudinal energy-absorbing structure, the rotating anti-collision wave guardrail absorbs collision energy through self-deformation or vehicle climbing, thereby changing the vehicle's driving direction and preventing the vehicle from crossing the road or entering the opposite lane. This will minimize the damage to the occupants. It is particularly prominent in preventing vehicles from crossing the road or crossing the central divider into the opposite lane, and preventing vehicles from getting out from under the guardrail. In the event of a collision, the degree of damage to passengers will be greatly reduced.

The rotating guardrail is made of high-strength composite materials, which is anti-collision, wear-resistant and has strong recovery power, which can prevent the rotating barrel from being smashed when it is impacted. Its cost is about 12 times that of ordinary guardrails, but it can effectively play the role of releasing force and guiding, converting the force of car impact into rotational kinetic energy, which can greatly absorb the impact force and greatly reduce the damage caused by traffic accidents.

5.Functions of the rotating guardrail components

(1) Column: a component driven vertically into the roadbed and is the primary stress-bearing component.

(2) Cross beam: used to fix the rotating barrel and connecting columns.

(3) Rotating barrel: It is placed outside the column, fixed between the upper and lower beams, and can rotate around the column.

(4) Bushing: installed on the inner wall of the rotating barrel, the touching part when the rotating barrel rotates.

(5) Gyratory circle: installed between the rotating barrel and the beam, used to maintain balance and promote rotation.

(6) Connecting frame: Its function is to connect the beams.

(7) U-shaped frame: the connecting piece between the beam and the column, used to fix the beam.

(8) Pad buckle: lined with cross beam and connected to U-shaped frame.

(9) Hoop: connects beams and columns, used to fix beams, suitable for specific types.

(10) Reflective strip: The reflective film attached to the rotating barrel serves to induce sight and ensure driving safety at night and in harsh environments.
