The invention discloses a multi-stage magnetic fluid damping load reduction and shock absorption type omnibearing land survey vehicle which comprises a magnetic fluid damping load reduction and shock absorption type protective walking assembly, an omnibearing circumferential laser scanning protective collecting assembly, a folding storage protective survey assembly and a petal-like crank arm driving type obstacle removing and sampling assembly. The invention belongs to the technical field of land measurement equipment, and aims to solve the problem that a measurement vehicle easily collides with an obstacle when moving too fast, magnetofluid is adopted to replace traditional hydraulic oil to serve as a hydraulic medium, and resistance generated when the magnetofluid passes through a permanent magnet is used as a power source for load reduction and shock absorption. Impact caused by collision is preliminarily buffered, then the impact force continues to be reduced through the damping effect, when the magnetic fluid in the pressure bearing chamber flows through the coil winding reel through the impact force, the magnetic fluid is affected by a magnetic field generated by the magnetic induction coil, and resistance is generated to further consume the impact force caused by collision.
本发明公开了一种多级磁流体阻尼降载减震型全方位土地测量车,包括磁流体阻尼降载减震型防护行走组件、全方位环向激光扫描防护收集组件、折叠收纳防护型测量组件和仿花瓣式曲臂驱动型清障取样组件。本发明属于土地测量设备技术领域,本发明针对测量车移动速度过快时容易碰撞到障碍物的问题,采用磁流体替代传统的液压油作为液压介质,利用磁流体经过永磁铁时产生的阻力来作为降载减震的动力来源,对碰撞带来的冲击进行初步缓冲,随后利用阻尼作用来继续减小冲击力,当冲击力使承压室内的磁流体流过线圈绕线筒时,磁流体受到磁感线圈产生的磁场影响,产生阻力来进一步消耗碰撞带来的冲击力。
