Abstract

The utility model discloses a movable isolation guardrail comprising a guardrail body, at least two guiding pipes or guiding holes are arranged on the guardrail body, fixed bars are arranged in the guiding pipes or the guiding holes and can slide up and down in the guiding pipes or the guiding holes to insert or pull out of fixed holes correspondingly pre-embedded on ground, bayoner lock devices are arranged on the fixed bars to lock the fixed bars to avoid falling, and rolling wheels are arranged on bottom of the guardrail body for moving. Rolling wheels are arranged on the bottom of the guardrail, so that the movable guardrail is convenient and laborsaving for isolating or opening crossing, the fixed bar arranged on the guardrail body can be inserted into or pulled out of the fixed hole correspondingly pre-embedded on ground, when impacted, the guardrail body can combined with foundation to greatly enhance anti-impact effect and avoid vehicle from rushing at opposite track to cause more traffic accident.

Description

Removable isolation guardrail

Technical field

The utility model relates to a kind of traffic safety facilities, relates in particular to a kind of isolation guardrail.

Background technology

Isolation guardrail is a kind of road safety facility that is widely used in road traffic, be that the warning vehicle that is provided with along the shoulder of Dangerous Area sails out of roadbed and the vehicle that prevents that is provided with along the median strip is swarmed into the protective equipment of subtend roadway, and for making the facility of the guarantee pedestrains safety that pedestrian and vehicle insulation be provided with, has the sight line of inducing human pilot, cause that it is vigilant or limit effects such as the pedestrian crosses arbitrarily, at some opening part that is provided with along the median strip, sometimes as required opening is isolated or open occasion setting, present interim guardrail adopts some steel frame constructions more, can not move freely, intensity is not high yet simultaneously, and it is very light to conduct oneself with dignity, vehicle one bumps then and knocks away gently, does not reach isolation effect.

The utility model content

Problem to be solved of the present utility model provides a kind of conveniently moving, the effective removable isolation guardrail of impact resistance.

The technical scheme that the utility model adopted is: removable isolation guardrail, comprise the guardrail body, described guardrail body is provided with at least two guide pipes or pilot hole, being provided with fixed bar in described guide pipe or the pilot hole can slide up and down in guide pipe or pilot hole, to insert or to pull out the corresponding pre-buried fixing hole in ground, also be provided with the bayonet lock device on the described fixed bar and avoid with locking after pull-up, roller also is equipped with so that move in described guardrail body bottom.

Described guardrail body preferably is the tower structure that comprises a hurdle and horizontal bar, preferably also is provided with the handle ring so that lift on fixed bar.

Further improve the impact resistance effect in order to play certain cushioning effect, described guardrail body side also is fixed with corrugated guardrail sheet or water horse.

In order when isolating, to cover the car light light that travels relatively simultaneously, also be fixed with shadow shield on the described guardrail body.

The beneficial effects of the utility model are: the utility model bottom is provided with roller, therefore the mobile protect fence realization is isolated opening or is open convenient and strength-saving, insert or pull out by the fixed bar fixing hole corresponding pre-buried that the guardrail body is provided with on ground, play fixation, the guardrail body is associated in when being impacted with ground, can strengthen the impact resistance effect greatly, avoid vehicle further to pour the subtend track and cause bigger traffic accident.
