Improved bridge device

Abstract

The present invention discloses an improved bridge device. The improved bridge device comprises an electrical connection seat fixedly installed in a bridge engine body and an electrical connection head connected with an electrical maintenance device, the electrical connection head is internally provided with a chute having an opening end facing forwards, a slid strip is smoothly installed in the chute, the upper and lower end surfaces of the slide strip are respectively provided with tooth strips, turning grooves intercommunicating with the chute are correspondingly arranged at the upper and lower end walls of the chute, penetrating turning grooves and putting holes having opening end facing towards the left are correspondingly arranged up and down in the electrical connection head, the putting holes are internally provided with insertion columns in a turning mode, the turning grooves are internally provided with tooth wheels fixedly connected with the insertion columns, the outer sides of the tooth wheels stretch into the chute to be cooperatively connected with the tooth strips, the side walls of the putting holes are internally provided with first arc grooves, the first arc grooves are internally provided with twisting springs, one ends of the twisting springs are fixedly installed in the first arc grooves, the other ends thereof are fixedly connected with the insertion columns, and the left ends of the insertion columns are provided with external screw threads.

Description

technical field [0001] The invention relates to the field of bridges, in particular to improved bridge equipment. 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. When plugging in, it only depends on the friction between the electric connector and the electric connector to keep it in a state of motion. This power supply state is extremely unstable. When you accidentally kick the electric connector or trip the power supply line, it is easy to The electrified maintenance equipment will be accidentally cut off due to the drop or loosening of the electrical connector; in addition, since the electrical connector is directly connected to the mains, and the conductive sheet inside is set relatively outside, this conductive sheet is easily damaged by metal Therefore, when a person who la...

[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. When plugging in, it only depends on the friction between the electric connector and the electric connector to keep it in a state of motion. This power supply state is extremely unstable. When you accidentally kick the electric connector or trip the power supply line, it is easy to The electrified maintenance equipment will be accidentally cut off due to the drop or loosening of the electrical connector; in addition, since the electrical connector is directly connected to the mains, and the conductive sheet inside is set relatively outside, this conductive sheet is easily damaged by metal Therefore, when a person who lacks safety awareness inserts a metal sheet or metal rod into the electrical connector, electric shock accidents are likely to occur, causing casualties and posing a greater safety hazard
