Efficient bridge device

Abstract

The invention discloses an efficient bridge device. The efficient bridge device comprises a fingerpost and a fixing body, wherein the fixing body comprises a bottom plate between a first bridge floorand a second bridge floor, the left side and the right side of the bottom plate are fixedly provided with fixing bolts respectively, and the upper sides of the fixing bolts are cooperatively providedwith bolts. A supporting column is arranged on the bottom plate, a rotary table is arranged between the bottom plate and the supporting column, a first electrical rotation motor arranged on the bottomplate is connected with the supporting column through a first rotary arm, a left cavity, an upper cavity, a right cavity and a lower cavity which are communicated are formed in the supporting column,and a movement guide groove communicated with the left cavity is formed in the left end face of the supporting column. The overall structure is simple, the device safely and stably runs, operation isconvenient, lifting and locking of the fingerpost are automatically controlled, the working efficiency of replacing the fingerpost is greatly improved, the fingerpost is easy, convenient and rapid toreplace, it only takes little time to complete replacement of the fingerpost, the influence on vehicle traffic in the fingerpost replacement process is reduced, and the efficient bridge device is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a quick beam device. Background technique [0002] In order to ensure the orderly and smooth passage of cars, many traffic signposts need to be erected on both sides of the bridge road surface to remind drivers and pedestrians of the direction of travel, etc. Most of the existing traffic signboards are installed on the top of the road. It is fixed on the support column by screws, bolts or welding. When the traffic sign needs to be replaced, it is often necessary to close the bridge deck. It takes a long time to replace the traffic sign, and it also needs to use a climbing car Contour operation, which has caused low replacement efficiency, troublesome operation and affects the normal traffic of traffic, so the installation method of the above-mentioned traffic sign is difficult to meet the existing use requirements.
