Abstract

The invention relates to a one-way traffic roadblock, which comprises a blocking arm and a base, wherein the base is fixedly arranged on the pavement, the blocking arm is provided with a fixed end and a free end, the fixed end is used for fixing one end of the blocking arm onto the base through movable connection, and the free end is connected with the base through an elastic body so that the free end of the blocking arm can do ascending and descending type opening and closing movement above the base. In the normal use, the free end of the blocking arm ascends, the free end of the blocking arm is pressed down by wheels when vehicles normally run on the roadblock, and the vehicles can normal pass the roadblock. When the vehicles run in a direction not allowed by traffic regulations, the ascended free end of the blocking arm blocks the wheels, and the wheels cannot pass the roadblock. The one-way traffic roadblock can be used for preventing the vehicles from running in the direction not allowed by traffic regulations on highway or one-way streets, the cost of the one-way traffic roadblock is low, the installation is convenient, the damage is not easy to occur, in addition, the reliability is high, and the unattended operation is realized.

Description

A kind of one-way traffic roadblock

Technical field

The present invention relates to field of traffic facilities, relate in particular to a kind of traffic roadblock.

Background technology

Occupy significant proportion because of the vehicle accident that causes of not observing traffic rules and regulations on the highway,, drive in the wrong direction when often having the driver to take advantage of the opposite not have vehicle to come and drive as not having on the one-way street of electronic eyes.These violation phenomenons only depend on traffic rules to come penalties to eliminate fully, need solve through technological means, how to accomplish on one-way street, and vehicle can't be driven in the wrong direction at all, are problems that needs solution.

Summary of the invention

The objective of the invention is in order to prevent that vehicle from driving in the wrong direction on highway or one-way street; A kind of one-way traffic roadblock is provided, and this traffic roadblock comprises stop arm and base, and base is fixed on the road surface; Stop arm has fixed end and free end; Fixed end is fixed on the base through an end that flexibly connects stop arm, and free end is connected with base through an elastic body, makes the free end of stop arm on base, can do the ascending/decending open and close movement.The stop arm free end rises when normal the use, and normal vehicle operation was to this roadblock last time, and wheel is subdued the stop arm free end, and vehicle can normally pass through this roadblock.In this roadblock last time if vehicle drives in the wrong direction, the stop arm free end of rise blocks wheel, and wheel can't be crossed this roadblock.

The present invention has obtained following technique effect:

Can thoroughly stop vehicle on highway or one-way street, to drive in the wrong direction through the inventor, installation cost of the present invention is cheap, and is easy for installation, be not easy to damage, and the high unmanned of reliability.

Description of drawings

Fig. 1 be on the unidirectional roadblock of the present invention no vehicle through out-of-date idle condition sketch map;

The view of Fig. 2 for having vehicle normally to cross on the unidirectional roadblock of the present invention;

Fig. 3 is the view that is stopped when having vehicle to drive in the wrong direction on the unidirectional roadblock of the present invention.

The specific embodiment

Understand and embodiment of the present invention for the ease of those of ordinary skills, the present invention is made further detailed description below in conjunction with the accompanying drawing and the specific embodiment.

See Fig. 1; Be unidirectional roadblock among the present invention at the schematic cross-section of vehicle heading, comprise stop arm 1 and base 2, base 2 is fixed on the road surface 5; Stop arm has fixed end 6 and free end 7; Fixed end is fixed on the base through an end that flexibly connects stop arm, and free end is connected with base through an elastic body 4, makes the free end of stop arm on base, can do the ascending/decending open and close movement.The stop arm free end rises when normal the use, and normal vehicle operation was to this roadblock last time, and wheel is subdued the stop arm free end, sees Fig. 2, and vehicle can normally pass through this roadblock.In this roadblock last time if vehicle drives in the wrong direction, the stop arm free end of rise blocks wheel, sees Fig. 3, and wheel can't be crossed this roadblock.

Embodiment 1: the unidirectional roadblock of spring

This roadblock can be divided into a lot of pieces to be lined up a line and has been installed to simultaneously on the vehicle ' road surface, and the polylith roadblock is lined up the roadblock group vertical with vehicle heading of an integral body, but every roadblock independent-lifting, and convenient many cars are parallel to be passed through.Sit and be rectangle at the end of every roadblock, and sunk type is installed, and base is lower than the road surface, and when stop arm rose, its free end height was stopping retrograde vehicle fully between 20～50CM.The stop arm fixed end is not higher than the road surface when mounted, and during normal vehicle operation, wheel can directly roll stop arm its free end is depressed, and does not hinder vehicle to pass through.

The free-ended elastic body of above-mentioned support is a spring, can realize through one or more springs, and each stop arm maximum is born pressure at 50～200KG; When the weight that rolls when wheel surpassed this numerical value, free end was depressed, and the maximum of this stop arm is born pressure and will be designed according to the normal weight of vehicle on the road; Can be well-behaved if the driver that too small meeting give to be driven in the wrong direction is organic; As have only 5KG, driver can look for weight to depress stop arm earlier, retrograde vehicle seize the opportunity through.It is excessive that the maximum of stop arm is born pressure, like 1000KG, can't stop arm be depressed during small-sized empty wagons cruising, vehicle through the time can be impaired.

Embodiment 2: the unidirectional roadblock of anti-slip type

One-way traffic roadblock to above-mentioned can also improve, and is two-sided composite bed at the stop arm extexine, and skin is processed by elastomeric material, and internal layer is processed by the indeformable material of rigidity.Internal layer can be guaranteed that roadblock is indeformable when heavy vehicle crosses and not damage like this, and skin can be guaranteed when vehicle crosses on stop arm non-slip.

In order to reach better skidproof effect; Above-mentioned elastomeric material surface design is the cone matsurface; A large amount of high-strength rubber cones are distributed in the stop arm external surface; The cone awl end, be connected its diameter 5～15mm with stop arm, circular cone height 10～20mm, and the beeline between the different cones is at 2～10mm.In order further to strengthen the antiwear property of non-skid property and raising cone; With the sharp ball-type cambered surface that is designed to cave in of cone awl; After promptly the awl point is scabbled; Cone becomes a frustum of a cone, the round diameter 2～5mm at frustum of a cone top, and the circle at this frustum of a cone top cut out the pitting of the inside rounding off of dark a 2～5mm from its center of circle.
