The invention provides an automatic limiting device for a slip form jack, and relates to the technical field of slip form jacks. The automatic limiting device of the slip form jack comprises a slip lifting jack body and a guide rod, the slip lifting jack body is arranged on the outer side of the guide rod in a sleeving mode, a top cover is arranged at the upper end of the slip lifting jack body on the outer side of the guide rod, a ring seat is arranged on the upper end face of the top cover, and the upper portion of the outer side of the ring seat is sleeved with a shell in a threaded mode. A cover plate is arranged at the upper end of the shell, a plurality of hole pricking structures are annularly arranged on the upper portion of the inner side wall of the shell, and a storage battery module is arranged on the inner side wall of the shell at the lower ends of the hole pricking structures. By controlling the extension of the multiple first hydraulic rods, the multiple first hydraulic rods push the multiple clamping blocks to slide along the multiple stepped grooves, and the multiple clamping blocks clamp the outer sides of the guide rods for locking, jack sliding caused by mechanical faults or external interference is prevented, and the stability of the formwork is ensured; maintenance and adjustment caused by unstable sliding and lifting of the jack are reduced.
本发明提供一种滑模千斤顶自动限位装置,涉及滑模千斤顶技术领域。该滑模千斤顶自动限位装置,包括滑升千斤顶本体与导向杆,所述滑升千斤顶本体套设在导向杆外侧,所述导向杆外侧滑升千斤顶本体的上端设有顶盖,所述顶盖上端面设有环座,所述环座外侧靠上处螺纹套接有壳体,所述壳体上端设有盖板,所述壳体内侧壁靠上处呈环形排列设有多个扎孔结构,多个所述扎孔结构下端壳体的内侧壁上设有蓄电池模块。通过控制多个第一液压杆延伸,多个第一液压杆推动多个夹块沿着多个阶梯槽进行滑动,多个夹块夹持在导向杆的外侧进行锁定,防止因机械故障或外部干扰导致的千斤顶滑动,确保模板的稳定性,减少了因千斤顶滑升不稳定而进行的维护和调整。
