Description

Technical Field

[0001] The invention belongs to the technical field of vehicle transportation, and in particular relates to a cargo anti-tilt device for a land transport vehicle. Background Art

[0002] Land transportation usually refers to transportation on land. The carrier of transportation usually refers to vehicles used for freight transportation, which is one of the main modes of cargo transportation. In remote and economically backward areas with rugged terrain, sparse population, underdeveloped railways and water transportation, roads are the main mode of transportation and play the role of transportation trunk lines. When fixing the goods on the vehicle, vehicles used for freight transportation usually use ropes to wrap and tie them up. The operation is cumbersome and unreliable, which can easily cause the goods to tilt and collide with the carriage when the vehicle turns, causing damage to the goods and causing property losses. In serious cases, the vehicle may lose its center of gravity and overturn, endangering the lives of the transport personnel. Therefore, based on the above defects, it is necessary to propose a better technical solution to solve the above technical problems. Summary of the invention
