AI Technical Summary
Technical Problem
The hydraulic cylinder is affected by temperature, and the change in hydraulic oil viscosity leads to unstable operation, causing the excavator boom to shake and affecting normal operation.
Method used
A hydraulic mechanism for lowering and preventing shaking of an excavator boom was designed. The mechanism uses a hydraulic jack to drive a rotating block, which moves a slide plate along the rotating shaft. The slide rod and the fastening ring cooperate to fix the rotating shaft and prevent shaking.
Benefits of technology
It effectively prevents boom and shaft vibration, improving the stability and convenience of excavator operation.

Abstract
The utility model relates to the technical field of anti-shake hydraulic mechanisms, in particular to a descending anti-shake hydraulic mechanism for a movable arm of an excavator, which comprises a mounting seat and a movable arm body, a supporting seat, a fixing plate and a rotating seat are fixedly connected onto the mounting seat, and the rotating seat is connected with the movable arm body through a hydraulic cylinder. A rotating shaft is rotationally connected to the supporting seat, and the movable arm body is fixedly connected with the rotating shaft; a cavity is formed in one end of the rotating shaft, a plurality of sliding rods arranged in an annular array are slidably connected into the cavity, a fixing ring is fixedly connected to one side of the supporting seat, and a plurality of clamping blocks are fixedly connected to the inner surface of the fixing ring. According to the swing arm, the fastening ring and the sliding rod can be effectively prevented from rotating, the effect of fixing the rotating shaft is achieved, then the swing arm body and the rotating shaft can be effectively prevented from shaking, the swing arm has the anti-shaking function, excessive shaking of the swing arm body is avoided, and an excavator can work more conveniently and more easily.
