Improved bridge facility

Abstract

The invention discloses a bridge facility, which comprises an electrical connection socket fixedly arranged in a bridge wall body and an electrical connection plug connected with electrical maintenance equipment. The upper and lower portions of the electrical connection socket are symmetrically and respectively provided with an insert slot, the opening of which faces right. The upper and lower portions of the electrical connection socket are symmetrically and respectively provided with a first sliding groove, a second sliding groove and a third sliding groove, the openings of which face to theinsert slots. A communicated sliding cavity is arranged between each first sliding groove and each second sliding groove; and the sliding cavity is slidably provided with a sliding plate. Each firstsliding groove is slidably provided with a sliding arm. Each second sliding groove passes through the corresponding insert slot and is slidably provided with a locking arm. The end surface, facing tothe corresponding insert slot, of the locking arm is provided with a first bevel surface. The sliding plate is fixedly connected with the locking arm and the sliding arm. The end surface, facing to the insert slot, of each sliding arm is provided with an electrical contact sheet. A communicated groove is arranged between each second sliding groove and each third sliding groove. Each second slidinggroove is slidably provided with a sliding bar.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an improved 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 lac...

[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 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
