Novel bridge facility

Abstract

The invention discloses novel bridge facility. The novel bridge facility comprises a bolt base and a power transmission part matched with the bolt base and connected with electrical maintenance equipment; screw thread blocks are symmetrically arranged on the right sides of the upper and lower end walls of the bolt base; screw thread holes are formed in the screw thread blocks; an upper inserting groove and a lower inserting groove with rightward groove openings are symmetrically formed in the bolt base up and down; an upper electric contact block and a lower electric contact block are mountedin the inner side end walls of the upper inserting groove and the lower inserting groove respectively; an upper rotary sleeve and a lower rotary sleeve are rotationally mounted at the left ends of theupper inserting groove and the lower inserting groove respectively; an upper rotary column and a lower rotary column are fixedly arranged at the left ends of the upper rotary sleeve and the lower rotary sleeve respectively; a first annular groove and a second annular groove are formed in the outer circles of the upper rotary sleeve and the lower rotary sleeve respectively; an upper electrical contact and a lower electrical contact are fixedly arranged on the outer side end walls of the first annular groove and the second annular groove respectively; and the upper electrical contact and the lower electrical contact are electrically connected with the upper electric contact block and the lower electric contact block respectively.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a novel 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 s...

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
