XT870H型挖掘装载机后部设有H型框架,框架两端设有支腿,该挖掘装载机挖掘作业时,需将2个支腿伸出,将其后部支起,使后轮离地,以保证挖掘作业的稳定性。挖掘动臂支座可在H型框架的轨道上左、右移,使挖掘作业灵活、高效。本文介绍该挖掘机支腿滑块的结构改进。1.支腿滑块结构该型挖掘装载机支腿截面为正方形,分别嵌套在H型框架两侧的方形支腿套筒内,通过支腿缸驱动其伸缩。每个支腿上部外侧设有4个上
There is an H-frame at the rear of the XT870H backhoe loader. Legs are provided at both ends of the frame. When the excavation loader is excavating, two outriggers need to be extended and the rear part of the outrigger is to be lifted to make the rear wheels off the ground. To ensure the stability of the excavation operation. The excavation boom support can be moved left and right on the track of the H-frame to make excavation work flexible and efficient. This article describes the structural improvement of the excavator leg slider. 1. Legs and Slider Structures The legs of the excavator loader are square in shape and are nested inside the square leg sleeves on both sides of the H-shaped frame, and are driven by the leg cylinders to expand and contract. There are 4 on the upper outer side of each leg
