The invention relates to the technical field of logistics transportation, and discloses a single-stand-column reciprocating type lifting cargo carrying table protection device for logistics transportation, which comprises a cargo carrying table, a lifting column is movably connected to the inner wall of the middle part of the cargo carrying table, a limiting mechanism is movably connected to the inner wall of the middle part of the cargo carrying table, and an energy supply mechanism is movably connected to the inner wall of the middle part of the cargo carrying table; the inner wall of the middle of the energy supply mechanism is movably connected with a speed limiting mechanism and a triggering mechanism. According to the single-stand-column reciprocating type lifting cargo carrying table protection device for logistics transportation, the cargo carrying table drives the magnetic ring to move, the magnetic ring drives the coil to operate, then the blocking block and the electrorheological fluid are used in cooperation, and therefore the speed limiting protection effect is achieved, when the magnetic ring rotates rapidly under the action of the lifting column, the induced electromotive force generated by the coil is large, and the safety of the cargo carrying table is improved. The hardening degree of the electrorheological fluid is increased, the resistance borne by the blocking block is increased, at the moment, the blocking force borne by the magnetic ring is also increased, and therefore the cargo carrying table runs in a certain constant state.
本发明涉及物流运输技术领域,且公开了一种物流运输用单立柱往复式升降载货台保护装置,包括载货台,所述载货台中部内壁活动连接有升降柱,载货台中部内壁活动连接有限位机构,载货台中部内壁活动连接有供能机构,供能机构中部内壁活动连接有限速机构,供能机构中部内壁活动连接有触发机构。该物流运输用单立柱往复式升降载货台保护装置,通过载货台带动磁环运动,磁环带动线圈运行,再通过阻塞块与电流变液的配合使用,从而达到限速保护的效果,当磁环在升降柱的作用下快速转动的时候,线圈产生的感应电动势较大,使得电流变液的硬化程度加大,阻塞块受到的阻力变大,此时磁环受到的阻碍力也变大,从而使载货台运行处于一定恒定状态。
