The invention discloses the technical field of hydraulic engineering equipment, and particularly relates to a hydraulic engineering safety device with a protection mechanism and an operation method of the hydraulic engineering safety device. The hydraulic engineering safety device comprises a hoisting box; an upper connecting rod is horizontally arranged at the upper end of the center in the hoisting box; the upper connecting rod is sleeved with a connecting wheel; the connecting wheel is sleeved with a hoisting cable; a protection box is welded to the center in the hoisting box; the protection box is arranged at the upper end of a hook; four protection cables are vertically connected in the protection box; safety protection is conducted on use of the hook; normal connection and swing of the hook are not affected under the action of self-rotating rings; a lower connecting rod is elastically and movably connected, so that when the hook is used for hanging a heavy object, buffering and pressure reducing are conducted; then the protection cables are driven to control the pressurizing assemblies to extrude the lubricating assemblies; lubricating oil is fed into the lower connecting rod and finally dripped into the connecting position of the connecting sleeve and the lower connecting rod; abrasion is reduced; and the service life is prolonged.

    本发明公开水利工程设备技术领域,具体为一种带有防护机构的水利工程安全装置及其操作方法,包括起吊盒,起吊盒内中心上端水平设有上连接杆,上连接杆上套接设有连接轮,连接轮上套接设有起吊缆,所述起吊盒内中心焊接设有防护盒,该装置通过在挂钩上端设置一个防护盒,在防护盒内竖直连接四个防护缆,对挂钩的使用进行安全防护,并且在自转环的作用下,不影响挂钩的正常连接摆动,通过将下连接杆进行弹性活动连接,随着挂钩进行挂设重物时,进行缓冲减压,然后带动防护缆控制加压组件对润滑组件进行挤压,将润滑油送入下连接杆内部,最终滴入连接套与下连接杆连接处,降低磨损,提高使用寿命。
