The invention relates to the field of arm supports, and discloses a telescopic arm support and engineering machinery. The telescopic arm support comprises an arm section (1), an arm pin assembly, a telescopic oil cylinder (3), a cylinder pin assembly, a connecting rod assembly and a driving part, the driving part can drive the arm pin assembly to move between a first locking position and a first unlocking position through the connecting rod assembly and synchronously drive the cylinder pin assembly to move between a second unlocking position and a second locking position. According to the scheme, the arm pin assembly and the cylinder pin assembly can be synchronously driven to move, and unlocking of the arm pin assembly and locking of the cylinder pin assembly or locking of the arm pin assembly and unlocking of the cylinder pin assembly are synchronously achieved, so that the arm section is allowed to move, stretch out and retract or be locked more quickly and conveniently, the locking and unlocking operation of the arm section is simplified, and the working efficiency is improved.
本发明涉及臂架领域，公开了一种伸缩臂架及工程机械，所述伸缩臂架包括臂节(1)、臂销组件、伸缩油缸(3)、缸销组件、连杆组件和驱动件，所述驱动件能够通过所述连杆组件驱动所述臂销组件在第一锁定位置和第一解锁位置之间移动且同步地驱动所述缸销组件在第二解锁位置和第二锁定位置之间移动。本方案可以同步地驱动臂销组件和缸销组件移动，同步地实现臂销组件的解锁及缸销组件的锁定或臂销组件的锁定及缸销组件的解锁，从而允许更快速方便地移动伸出收回臂节或将臂节锁定，简化了臂节的锁定解锁操作，提高了工作效率。
