Operation equipment driving arm and high-altitude operation vehicle

Abstract

The invention discloses an operation equipment driving arm which comprises a telescopic arm assembly and a safety lock, and further comprises a retraction detecting device and a locking driving device, wherein one end of the safety lock is rotatably connected with one of a base arm and a telescopic arm of the telescopic arm assembly; the other end of the safety lock is used for rotating to a clamping position when the telescopic arm retracts and being connected with the other of the telescopic arm and the base arm in a clamping manner so as to stop the telescopic arm from extending out; the retraction detecting device is used for detecting whether the telescopic arm retracts in place or not; and the locking driving device is used for driving the safety lock to rotate to the clamping position when the retraction detecting device detects that the telescopic arm retracts in place. In the operation equipment driving arm, the automatic locking effect of the safety lock can be automaticallyachieved through the locking driving device and the retraction detecting device, thereby avoiding the problem that an operator forgets to lock the operation equipment driving arm in the long-term driving process. The invention further discloses a high-altitude operation vehicle equipped with the above operation equipment driving arm.

Description

technical field [0001] The present invention relates to the technical field of operating equipment, more specifically, to an operating equipment driving arm, and to an aerial work vehicle including the above operating equipment driving arm. Background technique [0002] Safety devices are installed in the moving parts such as telescopic booms and telescopic outriggers of aerial work equipment to prevent danger or failure caused by offside or over-extension of telescopic moving parts. At present, the safety devices used on aerial work equipment mainly use safety locks One end of the safety lock is rotatably connected to the base arm of the telescopic arm assembly, and the other end can be rotated to engage with the telescopic arm when the telescopic arm of the telescopic arm assembly is retracted, so as to prevent the telescopic arm from stretching out when engaging. However, the rotation of the current safety locks is all manually operated, and the staff is in a long-term wo...
