Abstract

The utility model relates to a road traffic isolation guardrail, in particular to a movable type guardrail which comprises a guardrail body and support posts, wherein the guardrail body is provided with the plurality of support posts; the movable type guardrail also comprises a base, a motor, a driving wheel and a base cavity, wherein the base is arranged at the end where the support posts are close to the ground; and the base is internally provided with the base cavity which is internally provided with the motor; and a driving shaft of the motor is provided with the driving wheel. The movable type guardrail does not occupy the space and damage the road surface structure, overcomes the defects of the existing system, has rapid reaction speed, greatly improves the road capacity when in tidal transportation, greatly reduces the error, optimizes the road utilization rate, and guarantees the traffic safety simultaneously.

Description

The packaged type guardrail

Technical field

The utility model relates to a kind of road traffic isolation guardrail, relates in particular to a kind of packaged type guardrail.

Background technology

Carry out road " morning and evening tides traffic " control, on road, open up changeable driveway, and adapt to " morning and evening tides traffic " according to the current direction of wagon flow situation of change real time altering changeable driveway.

The changeable driveway mode that Canada's morning and evening tides traffic solution is taked is very simple, and lacquer has been drawn yellow dotted line between the per share track, and at the aerial suspension signal lamp of road section, vehicle is current according to the signal lamp indication.

The variable information plate that the signal lamp that utilizes directly over the track and crossing have also been used in Beijing and two metropolis, Shanghai solves the pressure of morning and evening tides traffic, carry out pilot in corresponding ancillary facility transformation and the better simply highway section of adjustment engineering, carry out out " but variation is to traveling lane sign ", on the lane markings board of newly setting up, article one, the sign of keeping straight on is being transformed to the fork-shaped sign, be exactly the sign that turns left then, like this, a track has become the left-hand rotation line with regard to moment from the craspedodrome line.Change for the ease of the track, ground guidance sign are wiped, replace the new-type sign that there is dotted line on both sides.One has 4 kinds of control models, and the one, the on-the-spot traffic police on duty control that uses a teleswitch; The 2nd, local program control; The 3rd, the commander center is by instruments monitor crossing road conditions, according to circumstances Remote; The 4th, regional computer networking signal system changes according near vehicle flowrate carries out Based Intelligent Control.

Though more than this method of merely adjusting the roadway direction of traffic mode that increases heavy traffic flow path direction runway by signal lamp simple and easy to operate, but using on those arterial highways, access, city that central isolation guardrail must be set is inapplicable, and the traffic participant traffic safety can not get ensureing in the lane change process, the lane change that is unfavorable for the driver is selected, and the raising of its traffic capacity is not optimal naturally.

Summary of the invention

The technical problem that solves:

The utility model provides a kind of packaged type guardrail, solved above-mentionedly describedly to cause the track garage that blocks up not smooth for each metropolis by the morning and evening tides traffic, and existing traffic guidance system and equipment can't be alleviated problems such as morning and evening tides traffic congestion.

The utility model is the technical solution problem by the following technical programs:

The utility model provides a kind of packaged type guardrail, comprises guardrail body, pillar, and the guardrail body is provided with several pillars, also comprises base, motor, driving wheel, base cavity pocket; The subaerial end of described pillar is provided with base, and base cavity pocket is set in the base, and motor is set in the base cavity pocket, on the driving shaft of motor driving wheel is installed.

Packaged type guardrail described in the utility model: also comprise driven pulley, described driven pulley is arranged on the outer wall of base by driven shaft.

Packaged type guardrail described in the utility model, the driven shaft of described driven pulley is parallel with driving shaft.

Packaged type guardrail described in the utility model, described guardrail body is connected with base by thread.

Packaged type guardrail described in the utility model, described motor are stepper motor.

Beneficial effect

The utility model utilization is installed on the guardrail not increasing that guardrail takes up room, do not destroy road structure, the drawback, the reaction speed that solve existing system are fast, improve morning and evening tides traffic road passage capability when taking place greatly, reduce and incur loss through delay, make road utilization rate to reach optimum significantly, guaranteed the safety of traffic simultaneously.
