Road bridge warning indicator

Abstract

A road bridge warning indicator comprises a mounting seat fixedly mounted in a bridge body and a mounting head matched with the mounting seat. The mounting seat comprises an inserting groove with an outlet facing the front end and electric connection grooves symmetrically formed in the two side walls of the inserting groove. Vertical sliding grooves are further formed in the rear ends of the electric connection grooves. Lead-in grooves communicating with the inserting groove are formed in the inner sides of the vertical sliding grooves. Partitioning parts are mounted in the vertical sliding grooves in a sliding mode. Pushing rods are mounted in the lead-in grooves in a sliding mode. The outer side ends of the pushing rods are fixedly connected with the rear ends of the partitioning plates, and the inner side ends of the pushing rods extend into the inserting groove. First elastic pieces are fixedly mounted in the rear end walls of the vertical sliding grooves. The front ends of the first elastic pieces are fixedly connected with the rear end walls of the partitioning plates. Electricity connection elastic sheets are mounted in the electric connection grooves.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a warning device for roads and bridges. Background technique [0002] Nowadays, the development of science and technology is getting faster and faster, the volume of boats is increasing and the number of vehicles is increasing sharply. Therefore, it is particularly important for the safe passage of vehicles on the bridge and boats under the bridge. In order to increase safe passage, warnings are usually installed on the bridge. The warning device is used to improve the maximum passing height of the sailing boat, avoid the sailing height from being too high and hit the bridge, or warn the sailing boat to slow down when the weather is bad and the light is poor. Since the warning device is installed at high altitude, it is necessary for the staff to install and maintain it It brings certain troubles, and the existing warning devices are usually fixed on the bridge body by screws, et...

[0002] Nowadays, the development of science and technology is getting faster and faster, the volume of boats is increasing and the number of vehicles is increasing sharply. Therefore, it is particularly important for the safe passage of vehicles on the bridge and boats under the bridge. In order to increase safe passage, warnings are usually installed on the bridge. The warning device is used to improve the maximum passing height of the sailing boat, avoid the sailing height from being too high and hit the bridge, or warn the sailing boat to slow down when the weather is bad and the light is poor. Since the warning device is installed at high altitude, it is necessary for the staff to install and maintain it It brings certain troubles. The existing alarms are usually fixed on the bridge body by screws, which makes the installation and maintenance operations troublesome.
