Description

[0002] The current ground crawler unmanned equipment has the problems of weak carrying capacity, short endurance time and insufficient flexible mobility, which limits its ability to carry out special operations with different upper equipment. Lightweight design is crucial to improve the mobility, endurance and carrying capacity of the unmanned platform. With the continuous development of integrated unmanned platform carrying equipment, the unmanned platform rotary bearing platform is facing the trend of lightweight and generalization. Although the existing large steel structure rotary bearing platform has good plasticity and easy processing characteristics, its problems such as heavy weight, poor adaptability, low strength and poor maintainability are particularly obvious in the application of unmanned platform rotary bearing platform, which affects the load ratio of the unmanned platform.

However, the existing integrally cast steel rotary bearing platform cannot meet the lightweight and generalization requirements, and is limited in its application range in the unmanned platform rotary bearing platform due to the flowability of the cast metal.

[0004] In order to adapt to the requirements of different carrying equipment, it is urgent to develop a new type of unmanned platform rotary bearing platform with lightweight, generalization and strong adaptability to meet the increasing demand for unmanned platforms.

[0005] The patent document with publication number CN207289876U discloses a bearing platform for clamp rotation, which is uniformly arranged with four limiting devices around the rotary platform, corresponding to four rotation angles, which are 0 degrees, 90 degrees, 180 degrees and 270 degrees in turn, but cannot achieve 360-degree rotation. At the same time, the platform lacks components for setting electrical equipment and protecting them. UTILITY MODEL CONTENTS
