Bridge facility

Abstract

The invention relates to bridge facility. The bridge facility comprises a pin seat fixedly mounted on a bridge wall and a pin head connected with electrical maintenance equipment, wherein a left end surface of the pin head is vertically symmetrically provided with a mounting groove with a port facing towards a left end, the mounting groove is movably equipped with a sliding sleeve extending leftwards, the sliding sleeve is provided with a middle hole, the middle hole is movably equipped with an electrical rod, a right end of the electrical rod penetrates through the sliding sleeve and is fixedly mounted on a right end wall of the mounting groove, a left end of the electrical rod penetrates through the sliding sleeve and is fixedly equipped with an electrical block, a left end of the sliding sleeve is vertically symmetrically provided with a first inclined surface, the pin seat is vertically symmetrically a jack which has a port facing rightwards and is matched with the electrical block, upper and lower end walls of the jack are symmetrically provided with sliding grooves facing towards the jack, and the sliding grooves are movably equipped with sliding blocks.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a bridge facility. Background technique [0002] Bridges are an important infrastructure for urbanization and an important guarantee for alleviating urban traffic congestion. In the construction of bridge infrastructure, many plug sockets are preset. These sockets are mainly used for plugging and power supply of electrified maintenance equipment in the later stage. However, the setting mode of these sockets is too simple, and they only rely on friction when plugging in with electrified maintenance equipment. Keeping the state of motion, this kind of power supply state is extremely unstable. When you accidentally kick the plug head or trip the power supply line, it is easy to cause the plug head to fall off and cause the electrified maintenance equipment to accidentally power off; in addition, because the bridge plug seat The setting height is limited, and the internal conductive sheet is ...

Problems solved by technology

In the construction of bridge infrastructure, many plug sockets are preset. These sockets are mainly used for plugging and power supply of electrified maintenance equipment in the later stage. However, the setting mode of these sockets is too simple, and they only rely on friction when plugging in with electrified maintenance equipment. Keeping the state of motion, this kind of power supply state is extremely unstable. When you accidentally kick the plug head or trip the power supply line, it is easy to cause the plug head to fall off and cause the electrified maintenance equipment to accidentally power off; in addition, because the bridge plug seat The setting height is limited, and the internal conductive sheet is set relatively outside. This conductive sheet is easily touched by a metal sheet or a metal rod. Therefore, when a person lacking safety awareness inserts a metal sheet or a metal rod into the socket When the temperature is high, electric shock accidents are prone to occur, causing casualties and posing a greater safety hazard
