Description

Technical Field

[0001] This utility model relates to the field of vehicle transportation and installation technology, and in particular to an automated positioning device for vehicle wheel chocks. Background Technology

[0002] Currently, in most freight transport and fluid storage and handling industries, vehicle slippage frequently occurs during loading and unloading. This inevitably leads to equipment damage, liquid spillage outside the vehicle, causing personal injury or death, environmental pollution, and property damage. To prevent slippage, it was later required that the vehicle's braking system be engaged after stopping. However, even with the braking system engaged, slippage accidents cannot be completely prevented due to vehicle malfunctions. The current practice is to manually place wheel chocks at the wheels. Manually placing wheel chocks is prone to problems such as improper placement, ineffective slippage prevention, and sometimes forgetting to place them. Furthermore, wheel chocks lack position sensing and signal feedback functions. Some wheel chocks are very heavy, making placement laborious and time-consuming, and many workers only make token adjustments without proper placement.

[0003] With the country's vigorous promotion of the use and popularization of intelligent equipment and robots in various industries, based on the current situation, there is an inevitable need for intelligent wheel stops that do not require human operation, have position sensing signal interlocks, can be correctly placed, and truly play the role of preventing vehicles from rolling away, in order to change the current situation.
