The invention relates to the technical field of winch limiting, in particular to an explosion-proof winch hydraulic limiting device. The device comprises a mounting block, a connecting shaft, a gear,fastening nuts, rolling bearings, a hydraulic control valve block, deep groove ball bearings, a worm and a limiting disc, wherein the connecting shaft is movably connected at the middle part of the top of the front face of the mounting block, the gear is fixedly connected to the outer surface of the connecting shaft in a sleeving mode, the gear is positioned in the mounting block, one fastening nut is fixedly connected to the side, away from the gear, of the outer surface of the connecting shaft in a sleeving mode, and the rolling bearings are fixedly connected at the bottoms of the fasteningnuts. According to the device, a switch on the top of the hydraulic control valve block is opened through extrusion by the rolling bearings to unload the pressure of a hydraulic system, so that the explosion-proof winch hydraulic limiting device stops the winch action; and the structure is simple, the installation and adjustment are convenient, the control stroke is long, the safety management andcontrol over the winch operation in an existing explosion-proof requirement can be effectively realized, the safety accident is prevented, and the safety is improved.

    本发明涉及卷扬限位技术领域,尤其涉及一种防爆卷扬液压限位装置,包括安装块、连接轴、蜗轮、紧固螺母、滚动轴承、液压控制阀块、深沟球轴承、蜗杆和限位盘,所述连接轴活动连接在安装块正面顶部的中部,所述蜗轮固定套接在连接轴的外表面,且蜗轮位于安装块的内部,所述紧固螺母固定套接在连接轴外表面远离蜗轮的一侧,所述滚动轴承固定连接在紧固螺母的底部。该发明滚动轴承挤压打开液压控制阀块顶部的开关卸载液压系统的压力,使得防爆卷扬液压限位装置停止卷扬动作,结构简单、安装调节方便、控制行程大,能够有效的解决现有的防爆要求中卷扬作业的安全管控,防止出现安全事故,提高了安全性。
