Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a bottom-powered mobile trolley. Background Art

[0002] In the production process of prefabricated parts such as box beams, a mobile trolley is used on the prefabrication site to move the mold platform. The mobile trolley for moving the mold platform is supported by running wheels and moves on the track on the ground. The mobile trolley is driven by a motor, and the motor is connected to the power supply through wires. The existing wires are suspended in the air for movement, and the aerial movement method will interfere with the operation on the trolley. Due to the existence of wires, in order to enable the mold platform to be cross-set, the wires of the trolley are connected to the power supply line through brushes on the power supply and even the power supply line (like the power supply of urban electric buses). The brush power supply needs to frequently enclose the brushes and is prone to disconnection. Utility Model Content
