Description

Technical Field

[0001] The utility model relates to the technical field of ore car tipping mechanisms, and particularly relates to an ore vehicle tipping mechanism. Background Art

[0002] As one of the key components of mining dump trucks, the performance and efficiency of the tipping mechanism are directly related to the vehicle's ability to perform rapid material loading and unloading tasks. Through a precisely designed mechanical structure, such mechanisms enable mining dump trucks to easily achieve smooth lifting and stable falling of the box body, thus efficiently completing the loading and unloading operations of heavy materials such as ores and coals. The tipping mechanism not only needs to have a strong load-bearing capacity but also good durability and reliability to cope with the harsh mining operation environment.

[0003] This mechanism is usually fixed on the bottom plate of the cargo box body and connected to the vehicle frame to form a stable support system. This connection not only ensures the stability and safety during the tipping process but also optimizes the material transportation efficiency. However, in the current production process, the installation of the tipping mechanism is often a relatively complex and time-consuming link. It requires on-site fitting and welding operations after the frame and the cargo box body are respectively manufactured. Although this method can ensure a high degree of fitting and sealing between the cargo box body and the frame, effectively preventing material leakage, it also brings a series of problems.

[0004] Firstly, it requires the production of the frame and the cargo box body to be carried out at the same location, or at least to be able to quickly and economically transport the two to the same location for assembly. This undoubtedly increases the additional transportation costs and time costs for some mining areas with remote geographical locations or inconvenient transportation. Secondly, when installing the tipping mechanism by on-site fitting and welding, once cracks, deformations or other failures occur during use, the difficulty of repair or replacement will increase significantly. This not only requires professional technicians to perform delicate operations but may also extend the repair cycle due to on-site conditions, thus affecting the normal operation of the vehicle and the production progress of the mine. Summary of the Utility Model

[0005] To solve the technical problems of high assembly difficulty and high assembly cost of the ore vehicle tipping mechanism in the prior art, the utility model provides an ore vehicle tipping mechanism.

[0006] To achieve the above object, the technical solution adopted by the utility model is as follows:

[0014] With the above structural solution, the structural strength of the main tipping seat is further enhanced.

[0015] As a preferred implementation of the tipping mechanism of a mining vehicle, the secondary tipping seat includes a secondary bottom plate, which is arranged parallel to the bottom plate of the cargo box body.
