Bridge facility

Abstract

The invention discloses a bridge facility, which comprises an electric connection seat fixedly installed in the bridge wall and an electric connection head connected with electrification maintenance equipment. Slots, the electrical connection seat is also provided with a first sliding groove, a second sliding groove and a third sliding groove with notches facing the insertion groove, the first sliding groove and the There is a communicating sliding chamber between the second sliding grooves, a sliding plate is installed slidingly in the sliding chamber, a sliding arm is slidingly installed in the first sliding groove, and a sliding arm is installed slidingly in the second sliding groove. The sliding groove passes through the insertion groove and is slidably installed with a locking arm. The end surface of the locking arm facing the insertion groove is provided with a first beveled surface. The sliding plate is fixedly connected to the locking arm. arm and a sliding arm, the end surface of the sliding arm facing the insertion slot is provided with an electric contact piece, a communication slot is provided between the second sliding slot and the third sliding slot, the A sliding bar is installed in the second sliding slot.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a 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 electrical maintenance equipment in the later stage. However, the setting mode of these electrical connectors is too simple. When connecting, it only depends on the friction force between the electric connector and the electric connector to keep it in a motionless state, while the electrified maintenance equipment needs to move constantly during work, which makes it extremely vulnerable to dragging and pulling of the power supply line. The plugging is loose due to the impact, which leads to the interruption of power supply, which seriously affects the normal use of power supply. The sheet is easily touched by the metal sheet or metal rod. Therefore, when a person who lacks safety ...

The plugging is loose due to the impact, which leads to the interruption of power supply, which seriously affects the normal use of power supply. The sheet is easily touched by the metal sheet or metal rod. Therefore, when a person who lacks safety awareness inserts the metal sheet or metal rod into the electrical connector, an electric shock accident is likely to occur, causing casualties, and there is a large Security risks
