The invention discloses a shear fork type hydraulic lifting platform. The shear fork type hydraulic lifting platform comprises a base and a shear fork type lifting mechanism installed on the base. A tray is mounted at the top of the scissor-type lifting mechanism; the scissor-type lifting mechanism comprises a front fork frame with one end movably mounted on the base and the other end fixedly mounted on the tray, and a rear fork frame with one end movably mounted on the tray and the other end fixedly mounted on the upper base; the middle parts of the front fork frame and the rear fork frame are movably connected through a rotating shaft; and a driving mechanism is mounted on the base and is in transmission connection with the rotating shaft. Lifting is carried out in a shear fork type hydraulic lifting mode, compared with a straight jacking mode and a chain pulling mode, the loading force borne by the lifting device is small, operation is stable in the lifting process, the unbalance loading phenomenon cannot occur, meanwhile, lifting positioning of the stay wire encoder and the PLC is accurate, the overall structure is firm and reliable, shaking cannot occur, safety of all parts can be guaranteed, and the lifting device is convenient to use. The service life is prolonged.
本发明公开了一种剪叉式液压升降平台,包括底座和安装在底座上的剪叉式升降机构;所述剪叉式升降机构的顶部安装有托盘;所述剪叉式升降机构包括一端活动安装在底座上、另一端固定安装在托盘上的前叉架,以及一端活动安装在托盘上、另一端固定安装在上底座的后叉架;前叉架和后叉架的中部通过一转轴活动连接;所述底座上安装有驱动机构,驱动机构传动连接转轴。本发明为剪叉式液压升降方式进行升降,相对于直顶式和链条拉拽式受到的载荷力小,并且在升降过程中运行平稳,不会出现偏载的现象,同时,拉线编码器和PLC的升降定位精准,整体结构牢固可靠,不会出现晃动能够保证各个部件的安全,使用寿命提高。
