Novel bridge facility

Abstract

The invention discloses a novel bridge facility comprising a plug pin seat and a plug pin head connected with an electric maintenance device, screw thread blocks are fixed on right sides of an upper end wall and a lower end wall of the plug pin seat, screw thread holes are arranged in the screw thread blocks, plug grooves that open to the right are arranged in the plug pin seat, upper and lower parts of the plug grooves correspond to each other, first power transmission pins are mounted in inner walls of the plug grooves, left ends of the plug grooves are provided with convex butting parts, left ends of the plug grooves are provided with arrangement grooves communicated with the plug grooves, first rotating chambers are arranged in left end walls of the arrangement grooves, upper and lower parts of the first rotating chambers correspond to each other, rotating rings are mounted in the rotating chambers in a rotatable manner, middle grooves of which left and right ends are communicated with each other are arranged in the rotating rings, four second power transmission pins are fixedly arranged on inner walls of the middle grooves, tooth discs fixedly connected with the rotating rings are arranged in the arrangement grooves, upper and lower parts of the tooth discs correspond to each other, and a toothed chain wheel connected with the tooth discs in a matched manner is mounted between the two tooth discs in a rotating manner.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a novel bridge facility. Background technique [0002] In the infrastructure construction of bridges, many electrical connectors are preset. These electrical connectors are mainly used for plugging and power supply of electrified maintenance equipment in the later stage. However, the setting mode of these electrical connectors is too simple. When plugging in with electrified maintenance equipment Just rely on the friction between the electric connector and the electric connector to keep the state of motion. This kind of power supply state is extremely unstable. If you accidentally kick the electric connector or trip the power supply line, it will easily cause the The electrified maintenance equipment will be powered off accidentally; in addition, due to the limited height of the electrical connector and the relatively outer conductive sheet inside, this conductive sheet is easily touched b...

[0002] In the infrastructure construction of bridges, many electrical connectors are preset. These electrical connectors are mainly used for plugging and power supply of electrified maintenance equipment in the later stage. However, the setting mode of these electrical connectors is too simple. When plugging in with electrified maintenance equipment Just rely on the friction between the electric connector and the electric connector to keep the state of motion. This kind of power supply state is extremely unstable. If you accidentally kick the electric connector or trip the power supply line, it will easily cause the The electrified maintenance equipment will be powered off accidentally; in addition, due to the limited height of the electrical connector and the relatively outer conductive sheet inside, this conductive sheet is easily touched by metal sheets or metal rods. Therefore, When people who lack safety awareness insert metal sheets or metal rods into the electric connector, electric shock accidents are prone to occur, causing casualties and posing a greater safety hazard
