The device comprises a stand column and a three-color lamp box, a driving mechanism is arranged in the stand column; the driving mechanism comprises a first chain wheel, a second chain wheel, a third chain wheel, a fourth chain wheel, a chain and a driving motor; a vertical moving open groove is formed in a vertical beam; a transverse moving open groove is formed in a cross beam, a first power connection block is embedded in the three-color lamp box,a second power connection block connected with the first power connection block in an abutting mode is arranged in the cross beam, a positioning mechanism is arranged on the three-color lamp box, andthe positioning mechanism comprises a positioning cavity, a double-end motor, a first bevel gear, a second bevel gear, a rotary positioning sleeve and a positioning column. The signal command device can well achieve the application, maintenance, replacement and repair of the three-color lamp box, is convenient to use and high in maintenance and replacement efficiency, does not greatly influence the normal passing of vehicles, and is practical, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of traffic signal command equipment, in particular to a signal command equipment for intelligent traffic. Background technique [0002] In order to ensure the orderly and smooth passage of cars, many traffic signs need to be erected on both sides of the road to remind drivers and pedestrians of the direction of travel, etc. Most of the existing traffic signs are installed at a higher position above the road , which is fixed on the supporting column by screws, bolts or welding. When the traffic signs need to be replaced and maintained, the lanes often need to be closed, and it takes a long time to replace the traffic signs, and it is also necessary to use a climbing vehicle or Climbing the ladder to perform equal-height operations results in low replacement efficiency, troublesome operation and affects the normal passage of vehicles. Therefore, the installation method of the above-mentioned traffic signs is d...

Problems solved by technology

[0002] In order to ensure the orderly and smooth passage of cars, many traffic signs need to be erected on both sides of the road to remind drivers and pedestrians of the direction of travel, etc. Most of the existing traffic signs are installed at a higher position above the road , which is fixed on the supporting column by screws, bolts or welding. When the traffic signs need to be replaced and maintained, the lanes often need to be closed, and it takes a long time to replace the traffic signs, and it is also necessary to use a climbing vehicle or Climbing the ladder to carry out equal-height operations, which results in low replacement efficiency, troublesome operation and affects the normal passage of vehicles, so the installation method of the above-mentioned traffic signs is difficult to meet the existing use needs
