Description

Technical Field

[0001] This utility model relates to a material handling device, and more particularly to a planar moving material handling device applicable to low-chassis vehicles. Background Technology

[0002] With the rapid growth in the number of motor vehicles in cities and the increasing scarcity of land resources, multi-level parking garages have been widely promoted and applied globally as an important way to solve the "parking difficulty" problem. Multi-level parking garages are characterized by high efficiency, intelligence, and convenience in storage and retrieval. As the core equipment of multi-level parking garages, the performance of vehicle handling equipment directly affects the efficiency and reliability of the entire parking system.

[0003] Currently, existing planar moving and handling equipment in the parking industry includes: comb-type handling equipment and clamping handling equipment. Comb-type handling equipment uses the lifting of the upper comb frame to cooperate with the comb teeth on the parking space to complete the parking and retrieval action. Clamping handling equipment mostly uses gears and clamping arms meshing or hydraulic cylinders to drive the clamping arms to rotate in order to achieve the handling action.

[0004] Although this type of handling equipment can move vehicles quickly, it still has the following drawbacks:

[0005] 1. Due to its large overall thickness, it cannot transport vehicles with low chassis, thus limiting its applicability.

[0006] 2. The walking device has poor impact resistance and is easily damaged, resulting in low reliability.

[0007] The information disclosed in this background section is intended only to enhance understanding of the overall background of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0020] The lead screw is mounted on the central axis of the chassis, and the slide plate assembly is mounted perpendicular to the central axis of the chassis.

[0021] The lead screw motor is used to drive the slide assembly to move.

The slide rails are arranged corresponding to the slide blocks, and each slide rail is arranged parallel to the central axis of the chassis.

[0034] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0035] 1. This utility model relates to a planar moving and transporting device applicable to low-chassis vehicles. Two symmetrically arranged trailer assemblies are mounted on the chassis. Each trailer assembly has a slotted hole. A turntable bearing for the clamping arm is mounted on the chassis. One end of the clamping arm has a pin that engages with the slotted hole. As the trailer assembly moves back and forth, it pushes the pin along the long axis of the chassis, while simultaneously moving within the slotted hole. This design reduces the overall thickness of the transporting device to only four plate-like structures: chassis, clamping arm, trailer assembly, and cover plate. The clamping arm and chassis are directly connected via the turntable bearing. The outer ring of the bearing is concealed within a countersunk hole in the chassis plate, and the inner ring is concealed within the clamping arm plate. This integrated design effectively reduces the overall thickness. Therefore, this design, with only four plate-like structures (chassis, clamping arm, trailer assembly, and cover plate), effectively reduces the overall thickness.

[0036] 2. This utility model provides a planar moving and transporting device applicable to low-chassis vehicles. The walking device provides driving force to the transporting device through an active wheel system. Each active wheel system includes a three-hole three-bearing drive system composed of a four-wheel drive synchronous gear and a transmission gear, as well as two four-wheel drive synchronous wheels. The structure of the four-wheel drive synchronous gear and the transmission gear is stable and reliable, and not easily damaged. At the same time, the four-wheel drive synchronous gear makes this design more impact-resistant than chain drive, further improving reliability. Attached Figure Description
