A traffic sign device

Abstract

The invention discloses an improved traffic signpost device. The improved traffic signpost device comprises a signpost and a fixing base, the fixing base comprises a base arranged between a first laneand a second lane, a supporting column is arranged on the base, a rotating disc is arranged between the base and the supporting column, a first motor is arranged on the base and is in power connection with the supporting column through a first rotating shaft, a left through groove, an upper through groove, a right through groove and a lower through groove which are communicated in sequence are formed in the supporting column, and a guide groove communicated with the left through groove is formed in the left end face of the supporting column. The improved traffic signpost device is simple in overall structure, safe and stable in operation and convenient to operate; signpost lifting and locking are automatically controlled, and thus the working efficiency of signpost replacement is greatlyimproved; besides, signpost replacement is easy, convenient and fast and can be completed within a short time, the influence on vehicle traffic during signpost replacement is reduced, and thus the improved traffic signpost device is suitable for application and popularization.

Description

Technical field [0001] The invention relates to the field of road traffic, in particular to a traffic sign device. 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 to go, etc. The existing traffic signs are mostly installed at higher positions above the road. It is fixed on the support column by screws or welding. When the traffic sign needs to be replaced, it is often necessary to close the lane, and it takes a long time to replace the traffic sign, and it also needs to use a climbing car to wait. High work, which results in low replacement efficiency, troublesome operation and affects the normal passage of vehicles. Therefore, the installation method of the above-mentioned traffic sign is difficult to meet the existing use requirements. Summary of the invention [0003] The technical problem to be solved by the present invent...

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 support column by screws, bolts or welding. When the traffic signs need to be replaced, the lane often needs to be closed, and it takes a long time to replace the traffic signs, and it is necessary to use a climbing car, etc. High operation, which has caused low replacement efficiency, troublesome operation and affects the normal passage of vehicles, so the installation method of the above traffic signs is difficult to meet the existing use needs
