Description

Technical Field

[0001] The invention relates to a car transporter and three-dimensional parking equipment. Background Art

[0002] With the continuous development of society, the number of cars has increased rapidly, and the problem of insufficient parking facilities has become increasingly prominent, resulting in the emergence of a large number of multi-story parking devices. The car transporters currently used in the field of intelligent multi-story parking mainly include vehicle-mounted plate types and wheel clamping types. Among them, the wheel clamping type is increasingly widely used due to its high parking efficiency, reduced garage floor height and reduced garage construction costs. However, the existing wheel clamping car transporter has a clamping structure with many transmission components, is relatively complex, and occupies a large area. The device is used under the car floor and is only applicable to some wide models. In addition, the front and rear clamping structures cannot adjust the spacing and are only suitable for models with a single wheelbase. In addition, the transporter can only move in a straight line, which is inconvenient to use. For heavy vehicles, the transporter has a relatively small carrying capacity, making transportation difficult and affecting work efficiency. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned deficiencies in the prior art and to provide a multifunctional car transporter and a three-dimensional parking system using the same. The multifunctional car transporter not only has fewer transmission components and occupies a small area, but is also applicable to vehicles of different wheelbases. In addition, the multifunctional car transporter has a large load-bearing capacity and is easy to use and transport, thereby improving work efficiency and greatly reducing the construction cost of a three-dimensional parking garage.

[0004] In order to achieve the above-mentioned purpose, the multifunctional car transporter of the present invention comprises a front chassis, a rear chassis, and a power supply. Both chassis are provided with two driving wheels, a drive motor, a transmission shaft and two shovel plates located on both sides.
