The invention relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder for a hydraulic cargo elevator, which comprises a cylinder body, a piston mechanism, a protection mechanism, a partition plate and a conveying mechanism are sequentially arranged in the cylinder body from top to bottom, and a push rod is fixedly connected to the upper surface of the piston mechanism. A first oil inlet pipe is fixedly connected to the position, located between the piston mechanism and the partition plate, of the outer circumferential face of the cylinder body in a penetrating mode, the protection mechanism comprises a connecting piece arranged on the lower side of the piston mechanism, a cross-shaped supporting plate is fixedly connected to the bottom end of the connecting piece, and a protection piece used for safety limiting is arranged on the cross-shaped supporting plate. Secondary safety limiting can be carried out in the working process of the hydraulic oil pump through the arrangement of the protection mechanism, when the hydraulic oil pump has an unexpected situation and hydraulic supporting force disappears, the protection mechanism can carry out secondary supporting on the pushing rod at the moment, harm caused by the unexpected situation is reduced, and the risk that the cargo elevator rapidly falls down is reduced.

    本发明涉及液压油缸技术领域,具体为一种用于液压货梯的液压油缸,包括缸体,所述缸体的内部从上至下依次设置有活塞机构、保护机构、分隔板和输送机构,所述活塞机构的上表面固定连接有推动杆,所述缸体的外圆周面位于活塞机构和分隔板之间固定且贯穿连接有第一进油管,所述保护机构包括设置在活塞机构下侧的连接件,所述连接件的底端固定连接有十字形支撑板,所述十字形支撑板上设置有用于保险限位的保护件,通过保护机构的设置在液压油泵工作的过程中可以进行二次保险限位,当液压油泵出现意外情况液压支撑力消失时,此时保护机构可以对推动杆进行二次支撑,降低意外情况发生时所带来的危害,降低货梯出现急速坠落的风险。
