The invention relates to the technical field of constructional engineering, in particular to a liftable support for constructional engineering and road engineering, which comprises a frame, wheels, a lever, a connecting rope, a lifting support, a lever adjusting mechanism and a balancing weight, the lever is mounted on the frame, the lever adjusting mechanism is placed on the frame, and the lever adjusting mechanism adjusts the fulcrum position of the lever. A connecting rope is installed on the lever, a balancing weight and a lifting support are fixedly installed at the two ends of the connecting rope respectively, the balancing weight and the lifting support are both connected with the frame in a sliding mode, and the lifting support and the balancing weight are trimmed according to the lever principle. According to the lever principle, the balancing weight with the fixed weight and the lifting support used for containing goods are placed at the two ends of the lever respectively, balance is achieved by adjusting the fulcrum of the lever, height unification of the goods after lifting every time is achieved, and pressure of the waist of a worker when the goods are placed is relieved.
本发明涉及建筑工程技术领域,具体为一种建筑工程及道路工程用可提升支架,包括车架、车轮、杠杆、连接绳、升降支架、杠杆调节机构、配重块,所述车架上安装有杠杆,所述车架上放置有杠杆调节机构,且杠杆调节机构调节杠杆的支点位置,所述杠杆上安装有连接绳,所述连接绳的两端分别固定安装有配重块和升降支架,且配重块和升降支架均与车架滑动连接,所述升降支架与配重块利用杠杆原理配平。本发明通过杠杆原理,在杠杆的两端分别放置有固定重量的配重块和用于放置货物的升降支架,通过调节杠杆支点达到平衡,实现货物每次升降后高度的统一,减轻工人放置货物时腰部的压力。
