Qingdao Taicheng Transportation Facilities Co., Ltd
The first manufacturer of exporting new type roller barriers in
China
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.
Product description
The rotating guardrail combines the advantages of traditional
barrier and new type energy -absorption anti-collision roller
barrel. It inserts the anti-collision roller barrel into
strengthened traditional barrier. When traffic accident happening,
the roller barrel can rotate freely on the columns, and through
this free rotation of the roller, they break down the impact force
of the car. it can efficiently resolve the impact energy by
converting the impact energy to rotational energy and pull the
accident car back to normal motion trail.
The roller barrel adopts the method of "one pillar and four
columns". By strengthening the performance and installation of the
columns and guardrails, it can effectively prevent vehicles from
crossing the barrier and driving out of the driveway. And it is
groundbreaking to use a rotating structure that supports elastic,
anti-collision and wear-resistant roller barrel on the columns, so
that the roller barrel can rotate freely on the columns, and
through this free rotation of the roller, they break down the
impact force of the car. The impact force perpendicular to the
guardrail is decomposed to the direction parallel to the guardrail,
which is effectively absorbed and reduced by the rotating bucket,
thus effectively reducing the consequences of traffic accidents.
Rotating barrels are made of EVA and polyurethane composites, which
are of high strength EVA and polyurethane material themselves are
elastic and anti collision and wear-resistant, can avoid smashed
when the roller barrel is impacted and effectively protect the
protection fence and the crew. Besides good anti-collision and wear
resistance, it has the advantages of anti chemical corrosion, anti
ultraviolet aging, weathering resistance and so on. It is not easy
to break, and the appearance is exquisite and not faded easily.
Under outdoor natural conditions, the service life is at least ten
years.
Working principle:
The rotating anti-collision guardrail combines the advantages of
traditional guardrails and new impact-resistant energy-absorbing
drums, and realizes the protection method of "one column and four
columns". The rotating anti-collision guardrail improves the
installation method by strengthening the performance of traditional
columns and guardrails. The rotating bucket can rotate freely on
the column. When an accident occurs, the free rotation of multiple
groups of anti-collision rotating buckets can effectively decompose
the impact force of the car, so that the impact energy
perpendicular to the direction of the guardrail can be converted
into rotational energy parallel to the direction of the
anti-collision rotating bucket. , The combination of this
rotational energy and the elastic energy of the rotating barrel can
pull the accident vehicle to maintain the normal driving direction
and speed, while avoiding the "head-to-head" situation of the
vehicle and the traditional guardrail in previous traffic
accidents, it can prevent the car from passing through the
guardrail and driving out. Drive lanes, thereby effectively
reducing the serious consequences of traffic accidents, and
protecting the personal safety of drivers and passengers to a great
extent.
Top rail: There are two rails in rolling barrier system, which
connects and supports the rollers horizontally. The upper rail is
known as Top rail. It is like a guard rail, made of steel. Top rail
splice is used to connect pipe with rails.
Bottom rail: From the two rails, the lower rail is called Bottom
rail. It also connects and supports the rollers horizontally. It is
like a guard rail, made of steel. Bottom rail splice is used to
connect pipe with rails.
PVC Pipe: The rollers are installed on PVC pipes, which allows the
rollers to rotate or roll freely. It is a vertical member
connecting both the rails and rollers. It is made up of PVC or
steel.
Stopper boards: It is a disc like board, which is installed between
rollers and rails, at both upper and lower sides. It is used to
guide objects back to road.
Shock absorbing roller: It is the main part of rolling barrier
system. The rollers are usually made up of Urethane or recycled
hard rubber. It absorbs the shock of vehicles, and convert impact
energy into rotational energy.
LED guide lamp: A small LED guide lamp is installed on PVC pipe. It
is installed on top of PVC pipe.
Reflective band: A reflective band is attached to the rollers to
give better visibility at night. Yellow coloured reflective
band/tape is used to increase visibility at night.
Product application
The appearance color of the rotating anti-collision barrel can be
customized into various warning colors, such as yellow, orange,
orange, red, green, etc. The high brightness reflection effect
makes the anti-collision barrel maintain high recognition and
warning degree in bad weather conditions such as night and rainy
days, catch the driver's eye, attract the driver's attention, and
reduce the accident rate. It is especially suitable for
installation in accident-prone areas such as tunnel entrances,
central isolation belts, rapid turning areas, complex
intersections, etc. Because of its good anti-collision performance,
it can also be used as various power facilities, parking lot
columns, large shelf corners and other objects. defensive
equipment.
