The anti-falling mechanism comprises two base protection plates, a rotating shaft is fixedly connected between the two base protection plates, the rotating shaft is sleeved with a jack jacking arm, the penetrating position of the jack jacking arm and the rotating shaft is rotationally connected, anti-falling assemblies are installed on the sides, close to each other, of the two base protection plates, and the anti-falling assemblies are fixedly connected with the rotating shaft. The anti-falling assembly is used for preventing a jacking arm of the jack from rotating reversely. Relates to the technical field of horizontal oil jacks, and is provided with an anti-falling assembly to prevent a jack jacking arm from rotating reversely, so that the situation that the jack jacking arm falls suddenly when a hydraulic system breaks down is effectively prevented, and the safety of the jack in the using process is greatly improved.
本发明公开了一种卧式油压千斤顶的防降机构,包括两个基护板,两个所述基护板之间固定连接有转轴,所述转轴上套设有千斤顶顶升臂,所述千斤顶顶升臂与转轴的贯穿处为转动连接,两个所述基护板相互靠近的一侧均安装有防降组件,所述防降组件用于防止千斤顶顶升臂逆向转动。涉及卧式油压千斤顶技术领域,通过设置防降组件,防止千斤顶顶升臂逆向转动,从而有效防止了千斤顶顶升臂在液压系统出现故障时突然下降的情况,极大地提高了千斤顶使用过程中的安全性。
