Bridge sign device

Abstract

The invention discloses a bridge sign device which comprises a pedestal, wherein a pushing cavity is arranged in the pedestal; sliding cavities are correspondingly arranged at the upper and lower sides of the pushing cavity; each sliding cavity is provided with a screw rod, and the right side end of each screw rod is in power connection with a first driving machine; a sliding block is arranged in the pushing cavity; pushing blocks capable of entering the sliding cavities are correspondingly arranged at the upper and lower sides of the sliding block; the pushing blocks are connected with the screw rods by threaded fit; an external thread joint part is arranged at the left side of the sliding block; a containing groove is formed in the external thread joint part; sliding holes are formed in the part, at the right side of the containing groove, of the sliding block; pin holes are formed in the corresponding parts, at the right sides of the sliding holes, on the inner wall of the pedestal; and a sign is correspondingly arranged at the left side of the containing groove. The bridge sign device disclosed by the invention is simple in structure, convenient to operate, high in safety and relatively stable in power supply connection, and effectively avoids the electric shock hazard when a person touches the pin holes.

Description

technical field [0001] The invention relates to the technical field of signboards used on bridges, in particular to a bridge signboard device. Background technique [0002] Various signboards can often be seen on some bridges, which are mainly used for traffic guidance to passing vehicles or to remind or warn vehicles passing on the bridge under bad weather conditions. However, the signage needs to be powered when it is working. In the prior art, the power supply is generally through the plug-in method. The power supply method is not stable. When the wind on the bridge is strong, the signboard is easily shaken due to the large force-bearing area. As a result, the plug port is loose and the power supply connection is interrupted, causing traffic disorder and seriously affecting the normal passage of vehicles on the bridge. At the same time, the traditional signage connection method makes the power port easily exposed to the outside world. It is very prone to conduction pheno...

However, the signage needs to be powered when it is working. In the prior art, the power supply is generally through the plug-in method. The power supply method is not stable. When the wind on the bridge is strong, the signboard is easily shaken due to the large force-bearing area. As a result, the plug port is loose and the power supply connection is interrupted, causing traffic disorder and seriously affecting the normal passage of vehicles on the bridge. At the same time, the traditional signage connection method makes the power port easily exposed to the outside world. Very prone to conduction phenomenon, there is a greater safety hazard
