The invention discloses a novel support capable of achieving ascending and descending. The novel support comprises an upper support body, a lower support body, universal trundles, a power unit (with a reversing valve), a synchronous valve, a left sealing plate, a right sealing plate and a height adjusting key. A hydraulic oil cylinder stretches out and draws back to drive the upper portion of the whole support to move up and down, when an ascending key is pressed, the power unit starts to work, hydraulic oil enters the bottom of the hydraulic oil cylinder after passing through the reversing valve and the synchronous valve, and then a piston rod of the hydraulic oil cylinder stretches out gradually to drive the upper half portion of the whole support to ascend; and when a descending key is pressed, the power unit starts to work, the reversing valve achieves reversing, the hydraulic oil enters the top of the hydraulic oil cylinder through an oil pipe, then the piston rod of the hydraulic oil cylinder gradually retracts to drive the upper half portion of the whole support to descend, and finally the hydraulic oil flows back to the power unit through the synchronous valve.
本发明申请是一种新型的可升降支架,包括上支架,下支架,万向脚轮,动力单元(带换向阀),同步阀,左右封板,高度调节按键;利用液压油缸的伸缩来带动整个支架上部的上下运动,当按动上升按键时,动力单元开始工作,液压油经换向阀、同步阀后进入液压油缸底部,然后液压油缸的活塞杆逐渐伸出,带动整个支架上半部上升;当按动下降按键时,动力单元开始工作,换向阀换向,液压油经油管进入到液压油缸顶部,然后液压油缸的活塞杆逐渐缩回,带动整个支架上半部下降,最后液压油经同步阀流回动力单元。
