Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of city crossing safety guardrail, should
Guard bar structure is simple, easy to use, easy to assemble, and maintenance cost is low.
To achieve the above object, the utility model adopts the following technical solution：A kind of city crossing safety guardrail, including shield
Column band and two hollow support columns being arranged symmetrically, the hollow support column is interior to be equipped with motor, driving wheel, driven wheel and transmission
Band, the motor and driving wheel are arranged in hollow support column bottom, and the output shaft of motor is connect by retarder with driving wheel, from
Position against the top is arranged in hollow support column in driving wheel, is driven band connection driving wheel and driven wheel, the transmission belt are equipped with
Several connecting plates, connecting plate are equipped with the pressing plate for compressing guardrail belt, and pressing plate is connect by bolt with connecting plate；Guardrail belt
One end is connect with the connecting plate on the transmission belt in a hollow support column, in the guardrail belt other end and another hollow support column
Transmission belt on connecting plate connection；The opposite side of two hollow support columns is equipped with the annular opening stretched out for connecting plate,
Motor in hollow support column is electrically connected with control device, and control device is disposed therein in a hollow support column.
The control device of the utility model can be connect by way of linking with traffic lights with traffic lights control signal.
In the above-mentioned technical solutions, the transmission belt is belt, and the driving wheel and driven wheel are belt pulley.
In the above-mentioned technical solutions, the transmission belt is chain, and the driving wheel and driven wheel are sprocket wheel.
In the above-mentioned technical solutions, the outside of the hollow support column is removable cover.
In the above-mentioned technical solutions, the control device is microcontroller or PLC（Programmable logic controller (PLC)）.
The utility model has the beneficial effects that：The guard bar structure is simple, easy to use, easy to assemble, and maintenance cost is low, control
Device controls the operating of motor, and so that guardrail belt cycle is moved up and down by transmission belt, does not need motor main story and reversion, structure
Simply, reliability is high；Also it can realize effectively opening and closing guardrail with traffic lights linkage.
Description of the drawings
