Abstract

The utility model discloses an express way abacus-type collision-preventing movable rail comprising a plurality of abacus-type movable frame units, steel pipe fixing frames at two ends and a lock. In each movable frame unit, a top beam, a middle beam and a bottom beam which are arranged in parallel and a plurality of rollers arranged longitudinally constitute an abacus frame. Each roller is provided with six rolling balls which are distributed in an abacus-type structure, i.e. two rolling balls are arranged at the upper side and the other four rolling balls are arranged at the lower side. The lower parts of the two ends of the bottom beam of each movable frame unit are provided with support disks and idler wheels. The movable frame units are connected with each other into a whole by connecting pins. The movable frame units at end parts are connected with the steel pipe fixing frames and locked by the anti-theft lock. The utility model has the advantages of delicate structure, strong anti-collision and buffering capability and convenient installation and opening, is suitable for the opening place of a separating belt at the center of an express way, a vehicle diverting place at a toll station and the outside of a toll house, and can improve the whole safety protection level.

Description

The crashproof movable rail of speedway abacus type
Technical field
The utility model relates to a kind of crashproof movable rail of speedway abacus type that is applicable to highway, urban road median opening place, charge station vehicle shunting place and charge station's tollbooth.
Background technology
Highway, urban road median opening are the interim default current places that lets pass of opening when handling in case of emergency current and half range construction of the highway sealing such as vehicle, ambulance vehicles for traffic accident, the movable rail that is provided with at the median opening place is as traffic safety facilities, mainly contain and isolate and crashproof effect, and easy unlatching characteristics should be arranged.Movable rail separates opposed vehicle, the effect that prevents that vehicle from turning around is arbitrarily arranged, there is simultaneously the errant vehicle of prevention to swarm into the crashproof effect that second accident is caused in the subtend track again, has an accident on the road surface or the highway section construction must be able to be opened rapidly when needing to adjust the track, so that vehicle is current smoothly.
The existing plug-in of China, telescopic and water-filling fill sand formula movable rail and do not possess due crashproof requirement.A lot of administrative departments break through opening part for fear of opposed vehicle and cause serious second accident, the movable rail that does not possess crashproof requirement of former setting is removed, having changed the median strip corrugated beam barrier is closed, make guardrail that certain crashproof ability arranged though do like this, but simultaneously freely stiff again, the characteristics that lost easy unlatching are exactly the requirement that does not meet current specifications.
Charge station vehicle shunting place needs steering capability that the movable rail of crashproof ability is well arranged again, and present telescopic movable guardrail does not possess the requirement of above-mentioned two aspects.Charge station's tollbooth of China does not generally lead and the buffering facility at present in addition.
The utility model content
The purpose of this utility model is to avoid the deficiencies in the prior art to provide a kind of speedway abacus type crashproof movable rail, and its guidance quality that has not only effectively strengthened guardrail has also strengthened guardrail buffering energy dissipating power.
The crashproof movable rail of speedway abacus type of the present utility model is by several abacus type movable frame unit, two ends steel pipe fixed frame and a lockset are formed, abacus type movable frame unit is by back timber, central sill, bottom girder, roller bearing, ball, pallet, roller is formed, by connecting pin each frame unit is connected as a single entity between each abacus type movable frame unit, the movable frame unit of end is connected with the steel pipe fixed frame, by the lock locking, abacus type movable frame unit is by the back timber that laterally be arranged in parallel, central sill, several roller bearings that bottom girder and parallel longitudinal are provided with form abacus type framework.
Be installed with six balls on the every roller bearing in described abacus type movable frame unit, wherein two are distributed between back timber and the central sill, have four to be distributed between central sill and the bottom girder, present two times four abacus type structure distribution.
The roller bearing that the back timber that laterally be arranged in parallel, central sill and the bottom girder of described formation abacus type movable frame unit and several parallel longitudinal are provided with, its cross section all is a round member.
The roller bearing of several parallel longitudinal settings of described formation abacus type movable frame unit passes the movable frame unit central sill of abacus structure, and two ends penetrate back timber and bottom girder respectively, freely rotate with ball when being subjected to external force.
When being subjected to external force, the ball on the roller bearing of several parallel longitudinal settings of described formation abacus type movable frame unit freely rotates around roller bearing respectively.
Ball on the roller bearing of several parallel longitudinal settings of the movable frame unit of described formation abacus structure is the flexibility or rigidity selection, and hollow or entity are made.
Described abacus type movable frame unit is by making with the lower member assembling: the back timber that laterally be arranged in parallel, central sill and bottom girder; The roller bearing that several parallel longitudinals are provided with; Ball; Pallet; Roller.
Ball surface on the roller bearing that several parallel longitudinals of described formation abacus type movable frame unit are provided with forms microspike to increase buffering energy dissipating and guide effect.
When collision happens, ball rotates around roller bearing, and roller bearing self is also rotatable, and the protective action of good guiding, buffering energy dissipating is played in the unit micro-strain of abacus type movable frame.In addition, that its also have to be opened is convenient, anti-collision level reaches multiple characteristics such as Am level, has strengthened the protective capacities of highway safety facility, the perfect globality of highway traffic safety protection system.Exquisite composition, novel structure, easy construction, cheap are suitable for popularizing use at highway, urban road median opening place, charge station vehicle shunting place.
