The invention provides a supporting device and operation machinery. The supporting device is arranged between a first arm support and a second arm support, and is used for supporting the second arm support. The supporting device comprises a supporting seat, an elastic piece, a supporting plate, a first limiting part a second limiting part, wherein the supporting seat is arranged on the first arm support; one end of the elastic piece is connected with the supporting seat; the supporting plate is connected with the other end of the elastic piece, and the supporting plate is used for supporting the second arm support; the first limiting part is slidably connected to the first end of the supporting seat, and at least one part of the first limiting part extend out of the supporting plate; the second limiting part is arranged at the second end of the supporting plate, and the second end is the end, away from the first limiting part, of the supporting plate; and the supporting plate is used for driving the first limiting part to slide in the direction of the second limiting part under the pressure action. According to the supporting device and the operation machinery, the first limiting part the second limiting part are correspondingly arranged at the two opposite ends of the supporting plate to clamp the second arm support, a limiting function for the second arm support is realized,and the generation of the deformation of the second arm support is reduced.
本发明提供了一种支撑装置和作业机械,支撑装置设于第一臂架和第二臂架之间,用于支撑第二臂架。支撑装置包括:支撑座,设于第一臂架上;弹性件,一端与支撑座连接;支撑板,与弹性件的另一端连接,支撑板用于支撑第二臂架;第一限位部,滑动连接于支撑座的第一一端,且第一限位部的至少一部分伸出支撑板;第二限位部,设于支撑板的第二端,第二端为支撑板远离第一限位部的一端;其中,支撑板在压力作用下用于带动第一限位部朝向第二限位部方向滑动。本发明通过在支撑板的相对两端分别设置第一限位部和第二限位部夹紧第二臂架,实现了对第二臂架的限位功能,减少了第二臂架变形的产生。
