Description

Technical Field

[0001] The invention relates to the field of bridge crane equipment, in particular to a novel bridge crane trolley conductive device. Background Art

[0002] Single-beam bridge cranes usually hang C-shaped groove beams on the main beam, with a spacing of 1.5 to 2 meters between the C-shaped groove beams. A full-length C-shaped guide groove is hung at the end of the beam, and a guide pulley is hung and installed in the full-length C-shaped groove to connect the trolley power supply line to the guide pulley. The trolley is connected to the conductive rod, and the top of the conductive rod is fixed to the wire. When the trolley moves, it drives the conductive rod, and then drives the guide pulley to move, so that the trolley can move and power the entire span of the main beam. However, since the full-length C-shaped guide groove is not a whole piece of material, there will be a joint in the middle. Due to installation errors, the C-shaped guide grooves on both sides of the joint will be misaligned, and the guide wheel will be stuck when passing through the joint. In addition, during the use of the bridge crane, it often stops and starts, generating inertial impact force. Under the influence of the conductive wire, the conductive pulley becomes more and more stuck. When the trolley moves, the resistance of the power supply rod increases, and the trolley conductive rod is often deformed and bent, or the guide groove is deformed, or the guide pulley is damaged. This area often requires repair and maintenance, which seriously squeezes normal usage time and affects normal production. Summary of the invention
