Problems solved by technology

The lifting mechanism of the monorail self-propelled trolley generally uses a lifting hoist or a motor-driven chain structure to achieve lifting, and the lifting hoist or motor-driven chain is prone to horizontal shaking
Therefore, during the operation of the monorail self-propelled trolley, there are disadvantages such as large amount of workpiece shaking, unstable operation, and large vibration during the lifting process. It is not suitable for occasio

Abstract

The invention provides a dual-track self-traveling trolley mechanism which is stable in running, low in oscillation level and vibration degree in a lifting process, and precise in positioning. The dual-track self-traveling trolley mechanism comprises I-shaped steel for fixing dual tracks, dual tracks, a traveling mechanism traveling on the dual tracks through traveling wheels, a lifting mechanism fixed below the traveling mechanism and a lifting appliance connected below the lifting mechanism through movable hanging strips, wherein the traveling mechanism is provided with a positioning guiding sleeve matched with a positioning guiding device on the I-shaped steel for positioning, the lifting mechanism is of a horizontal framework type, and two groups of the movable hanging strip are arranged on mounting supports on two sides of the framework of the lifting mechanism in parallel. Compared with the traditional single-track self-traveling trolley mechanism which is lifted by a chain structure driven by a lifting block or an electric motor, the dual-track self-traveling trolley mechanism has the advantages that the oscillation of the lifting appliance in a traveling process and the vibration of the lifting appliance in a lifting process can be alleviated, and the lifting appliance can be kept stable and can be positioned accurately.

Description

technical field [0001] The invention relates to the technical field of self-propelled trolley conveyor lines, in particular to a double-track self-propelled trolley mechanism. Background technique [0002] The self-propelled trolley conveyor line is widely used in the transfer and storage of the lower body assembly, the left and right side panels, the roof assembly, the body frame assembly, the body in white and the painted body in the automobile manufacturing process. Its main features are high conveying efficiency, low failure rate, low noise, no pollution, convenient equipment maintenance, high degree of automation, and the ability to realize multi-vehicle mixed line production. The currently widely used self-propelled trolley conveyor lines are mainly monorail self-propelled trolley conveyor lines. The lifting mechanism of the monorail self-propelled trolley generally uses a lifting hoist or a motor-driven chain structure to achieve lifting, and the lifting hoist or mot...
