Description

Technical Field

[0001] This utility model relates to the technical field of semi-trailer accessories, and in particular to an anti-rollover structure for unloading semi-trailers. Background Technology

[0002] In the bulk cargo transportation sector, semi-trailers frequently overturn when unloading materials such as sand, gravel, and grain. This is due to the rapid shift in the cargo's center of gravity, which generates significant lateral tilting moments. Existing anti-rollover technologies have the following main shortcomings:

[0003] Rigid support has poor adaptability: Traditional fixed outriggers are L-shaped integral welded structures with non-adjustable support span. When the semi-trailer's load changes or the working site is limited (such as narrow unloading areas or ramp sites), the outriggers cannot match the actual needs—insufficient span results in weak support, while redundant span obstructs the working space.

[0004] Insufficient installation expandability: The fixed structure cannot dynamically adjust the support points according to the load. Under heavy loads, additional auxiliary outriggers need to be welded, while under light loads, extra components need to be disassembled, resulting in cumbersome operations and damage to the vehicle structure. Therefore, a rollover prevention structure for semi-trailer unloading is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to propose an anti-rollover structure for unloading semi-trailers, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, one embodiment of the present invention provides an anti-rollover structure for unloading semi-trailers, including a semi-trailer connector, a main rod, and a sleeve.
