Description

Technical Field

[0001] The invention relates to the technical field of construction machinery, and in particular to a lifting mechanism of a vertical lifting mechanical parking equipment. Background Art

[0002] In cities where land resources are increasingly scarce and the automobile industry is growing, vehicle parking is receiving more and more attention, and mechanical parking garages are increasingly valued by users in urban public parking lots. In recent years, various cities have introduced policies to encourage social capital to invest in the operation and construction of public parking lots. Many companies have seized this opportunity to invest in the construction and operation of urban mechanical public parking lots. The investment and construction of public parking lots using mechanical parking garages not only plays a good role in alleviating the problem of urban parking difficulties, but also achieves certain economic results in investment, construction and operation, and companies can also gain benefits.

[0003] Vertical lifting mechanical parking equipment is widely installed and used in city centers and densely populated places due to its small footprint, high space utilization, fast access speed, and high efficiency. Outdoor independent equipment can be installed, and the equipment can be decorated according to the surrounding environment to make it consistent with the urban landscape. It can also be installed inside a building, and indoor independent equipment or attached equipment can be installed to achieve fully enclosed management. When parking a car, the lifting mechanism is used to lift the vehicle or the vehicle loading plate to the designated layer, and then the transverse mechanism installed on the lifting mechanism is used to send the vehicle or the vehicle loading plate to the parking space; when picking up a car, the transverse mechanism is used to send the vehicle or the vehicle loading plate on the designated parking space into the lifting mechanism, and the lifting mechanism is lowered to the vehicle entrance and exit, and the garage door is opened for the driver to drive the vehicle away.

[0004] As the most important component, the lifting mechanism plays a vital role in the entire equipment. At present, there are two installation methods for the lifting mechanism: top installation and steel structure middle installation. The top installation is a vertical closed-loop transmission system composed of a lifting chain, a balance chain, a sprocket (or a wire rope, a pulley), a vehicle-carrying plate, and a counterweight, etc., with a power of 18.5-30kw. The lifting mechanism is connected by a lifting chain (or) wire rope through a coupling device to realize the lifting and lowering of the vehicle-carrying platform. This type of structure is relatively complex. In addition to the difficulty of installing the mechanism as the height increases, due to its special steel structure (additional counterweight guide rails are required), and there is no additional installation platform, manual safety cannot be guaranteed. Although the middle installation has made a lot of simplifications to its structure and eliminated the counterweight and guide rails, the installation and maintenance costs caused by the change in its height will be greatly increased. Therefore, the structural and construction costs of the above-mentioned installation methods are relatively high, and pose a hidden danger to personal safety.

[0005] Based on this, a vertical lifting mechanical parking equipment lifting mechanism is proposed. Summary of the invention
