Description

Technical Field

[0001] The utility model relates to the technical field of vertical circulation type stereo parking equipment, in particular to a toothed chain type safe and stable transmission system and a vertical circulation type stereo parking garage using the system. Background Art

[0002] Currently, all vertical circulation garages on the market are motor-driven, but the transmission systems used to control these motors vary significantly. The transmission system is a crucial component of vertical circulation garages, and its efficiency and stability are crucial indicators for evaluating whether a garage meets standards. Most existing vertical circulation garages utilize a single drive shaft, with the motor directly driving the shaft, which in turn drives a chain. The chain is typically located on one side of the garage, relying on a single-sided transmission system to drive the vehicle loading platform. While simple, this structure suffers from overall structural imbalance and instability, which can lead to increased transmission system misalignment over time. Traditional chain drives are also prone to slippage and instability, compromising the safe operation of the equipment. Furthermore, the typical transmission system on the market uses a dial that simultaneously moves a chain pin. As the garage load increases, the meshing area is prone to deformation, making it incapable of meeting the load requirements of a heavy-duty garage. Utility Model Content
