Novel bridge facility

Abstract

The invention discloses a new type of bridge facility, which includes an electrical connection seat and an electrical connector connected with electrification maintenance equipment. The left end face of the electrical connector is fixedly installed with front and rear equidistant plug-in shafts, and the left end of the plug-in shaft extends outwards to generate electricity The left end of the plug-in shaft is provided with an external thread; the right side of the upper and lower ends of the electrical connection seat is fixed with a fixing block, the fixing block is provided with a screw hole, and the front and rear of the electrical connection seat are equally provided with notches facing to the right. Inserting cavity, the left end of the inserting cavity is provided with a transfer groove communicated with the inserting cavity, the left end of the transfer groove is provided with a cavity communicated with the transfer groove, the transfer groove is provided with a circular arc groove, and the upper end of the circular arc groove is provided with a communicating circle The installation groove of the arc groove, the adapter frame is rotatably installed in the adapter groove, the middle part of the adapter frame is provided with a middle groove that communicates with the left and right, and the inner wall of the middle groove is provided with an inner thread that matches the outer thread. .

Description

technical field [0001] The invention relates to the field of bridges, in particular to a novel 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 electrified maintenance equipment and maintenance equipment in the later stage. When the electrical maintenance equipment is plugged in, it only relies on the friction between the electrical connector and the electrical connector to keep it in a stationary state, while the electrical maintenance equipment needs to move continuously during work, which makes it extremely easy to be dragged, The influence of pulling the power supply line causes the plug connection to become loose, leading to the interruption of the power supply, which seriously affects the normal use of power supply. , this kind of conductive sheet is easily contacted by metal sheets or metal rods. Therefore, w...

[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 and maintenance equipment in the later stage. When the electrical maintenance equipment is plugged in, it only relies on the friction between the electrical connector and the electrical connector to keep it in a stationary state, while the electrical maintenance equipment needs to move continuously during work, which makes it extremely easy to be dragged, The impact of pulling the power supply line causes the plug connection to become loose, leading to the interruption of the power supply, which seriously affects the normal use of power supply. , this kind of conductive sheet is easily contacted by metal sheets or metal rods. Therefore, when people who lack safety awareness insert metal sheets or metal rods into the electric connector, electric shock accidents are prone to occur, causing casualties. There is a big security risk
