Bridge device

Abstract

The invention discloses a bridge device. The bridge device comprises a stand column, a cross plate and an electric joint, wherein the cross plate is fixed on the top of the stand column and stretches towards the left side and the electric joint is cooperatively connected with the cross plate. An inserting groove is arranged in the end face of the left side of the stand column. A second electric connection needle is arranged on the inner wall of the right side of the inserting groove. A sliding connection groove is arranged in the end face of the bottom of the left side stretching segment of the cross plate. A first spiral rod which left-right stretches is arranged in the sliding connection groove. A push block is cooperative connected with the first spiral rod in a spiral thread manner. A first transmission cavity is arranged in the cross plate on the left side of the sliding connection groove. A first sliding connection cavity is arranged in the cross plate under the first transmission cavity. A second transmission cavity is arranged in the cross plate on the left side of the sliding connection groove. A first rotation connection shaft which left-right stretches is arranged in the second transmission cavity. The right side end of the first rotation connection shaft is connected with an electric rotation machine. The bridge device is simple in structure, capable of achieving automatic control of insertion connection, power-up connection and stretching out of blocking blocks, high in working efficiency and high in safety.

Description

technical field [0001] The invention relates to the technical field of bridge facilities, in particular to bridge equipment. Background technique [0002] In the daily maintenance of some bridges, electrified maintenance equipment is often used. The electrified equipment needs to be plugged in to provide power before it can be used. The existing power supply for electrified equipment is generally plugged in manually. However, due to electrification The voltage required for the equipment to work is relatively high, and the stability of the manual plugging is poor. During the plugging process, arcs are likely to occur, and the generation of arcs is likely to cause electric shock to the user. There is a certain potential danger to the user, which will cause safety accidents and cause Casualties, and there is no protection device when plugging in the power supply is easy to loosen or cause damage to the plug connector due to accidental touch by personnel, which has great disadva...
