Abstract

This invention discloses a simple chain-type lifting and balancing chain structure for a multi-level parking garage. It includes a vehicle platform, left and right steel frame columns located on the left and right sides of the platform, and a lifting mechanism for driving the platform's lifting and lowering. The lifting mechanism includes a lifting motor, a double-row lifting chain, and a balancing chain. The lifting motor is fixedly mounted on the upper end of the left steel frame column. A double-row sprocket is mounted on the motor shaft. Left and right third-row sprockets are respectively located on the left and right sides of the vehicle platform. During lifting and lowering, when the double-row lifting chain moves upward, the balancing chain follows to keep the platform horizontal. Therefore, only one double-row lifting chain is needed to drive the lifting and lowering of the vehicle platform, while the balancing chain maintains its horizontal position. The structure is simple, easy to install, highly safe, and occupies little space.

A double-row sprocket 7 is mounted on the motor shaft of the lifting motor 4. A left third-row sprocket 8 and a right third-row sprocket 9 are respectively located on the left and right sides of the platform 1. One end of the double-row lifting chain 5 is fixedly connected to the left steel frame column 2, and the other end is sequentially connected to the lower ends of the double-row sprocket 7 and the left third-row sprocket 8. The lower sides of the side and right three-row sprockets 9 are engaged and fixed to the upper end face of the right steel frame column 3. One end of the balance chain 6 is fixed to the lower end face of the left steel frame column 2, and the other end is engaged with the upper side of the left three-row sprockets 8 and the lower side of the right three-row sprockets 9 in sequence and fixed to the upper end face of the right steel frame column 3. When lifting, when the double-row lifting chain 5 moves upward, in order to keep the vehicle platform 1 horizontal, the balance chain 6 will follow and move to keep the vehicle platform 1 horizontal. Thus, only one double-row lifting chain 5 is needed to drive the lifting and lowering of the vehicle platform 1, and then one balance chain 6 is used to keep the vehicle platform 1 horizontal. The structure is simple, easy to install, and has high safety and small space occupation.
