The invention discloses a hydraulic oil cylinder, a lifting working platform hydraulic system and a lifting working platform. The hydraulic oil cylinder comprises a cylinder barrel, a first through hole and a second through hole, and the first through hole and the second through hole are formed in the cylinder barrel in the axis direction of the cylinder barrel; the piston is installed in the cylinder barrel and slidably connected with the cylinder barrel, the piston is connected with the piston rod, the piston and the piston rod divide an inner cavity of the cylinder barrel into a large cavity and a small cavity, and a third through hole used for communicating the large cavity with the small cavity is formed in the piston; and the valve seat is mounted on the cylinder barrel, is used for inputting hydraulic oil into the inner cavity of the cylinder barrel through the first through hole and/or the second through hole, and is also used for discharging the hydraulic oil from the inner cavity of the cylinder barrel through the first through hole and/or the second through hole. Welding oil pipes are omitted, the external space of the hydraulic oil cylinder is released, the hydraulic oil cylinder has the advantages of being simple in appearance structure, flexible and adjustable in valve seat position and the like, oil pipe welding and interference damage risks are eliminated, the arrangement limitation of the hydraulic oil cylinder is reduced, and the safety of a system is improved.

    本发明公开一种液压油缸、升降工作平台液压系统和升降工作平台,液压油缸包括:缸筒,在缸筒上设置有沿缸筒的轴线方向具有设定距离的第一通孔和第二通孔;安装在缸筒内与缸筒滑动连接的活塞,活塞与活塞杆连接,活塞和活塞杆将缸筒的内腔分为大腔和小腔,活塞上设置有用于连通大腔和小腔的第三通孔;安装在缸筒上的阀座,阀座用于通过第一通孔和/或第二通孔将液压油输入缸筒的内腔,还用于通过第一通孔和/或第二通孔将液压油从缸筒的内腔中排出。本发明取消了焊接油管,释放液压油缸的外部空间,具有外形结构简单、阀座位置灵活可调等特点,消除了油管焊接和干涉损坏风险,降低了液压油缸布置的局限性,提升了系统的安全性。
