Embodiment Construction

[0017] refer to Figure 1 to Figure 3 , the present invention provides a four-section boom telescoping mechanism for an aerial work vehicle, comprising a first arm body 10, a second arm body 20, a third arm body 30, and a fourth arm body 40. The first arm body 10 is provided with a drive Mechanism 50, the output end of the driving mechanism 50 acts on the second arm body 20, and is used to drive the second arm body 20 to perform telescopic movement relative to the first arm body 10, the second arm body 20, the third arm body 30, the fourth arm body The bodies 40 are respectively connected by a transmission mechanism. When the second arm body 20 performs telescopic movement, the third arm body 30 relative to the second arm body 20 , and the fourth arm body 40 performs synchronous telescopic movement relative to the third arm body 30 . The synchronous telescopic movement between the arm bodies makes the telescopic efficiency of the four-section boom high. It is suitable for aeri...

Abstract

The invention discloses a four-arm telescopic mechanism of an aerial work vehicle. The four-arm telescopic mechanism comprises a first arm body, a second arm body, a third arm body and a fourth arm body, wherein the first arm body is provided with a drive mechanism; the output end of the drive mechanism acts on the second arm body and is used for driving the second arm body to do telescopic motion relative to the first arm body; the second arm body, the third arm body and the fourth arm body are connected through transmission mechanisms; and when the second arm body does telescopic motion, the third arm body does synchronous telescopic motion relative to the second arm body, and the fourth arm body does synchronous telescopic motion relative to the third arm body. The arm bodies can do synchronous telescopic motion, the telescopic efficiency of four arms is high, the four-arm telescopic mechanism is suitable for the aerial work vehicle and a work platform, and the work performance of the telescopic arm aerial work vehicle can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of high-altitude operation equipment, in particular to a four-section boom telescoping mechanism of an aerial work vehicle. Background technique [0002] The multi-stage telescopic boom is one of the core components of the telescopic boom aerial work vehicle. The telescopic mechanism is one of the core components of the telescopic boom, and the different telescopic methods directly affect the safety of the telescopic boom and the performance of the vehicle. At present, most of the telescopic booms of the telescopic boom aerial vehicles adopt the telescopic method of multi-stage oil cylinders. While the cost is high, the number of jib sections should not be too many, which is far from meeting the requirements of the multi-section jib telescopic jib. Contents of the invention [0003] The purpose of the present invention is to provide a four-section boom telescoping mechanism for an aerial work vehicle, wh...
