Telescopic pipeline conveying device and high-altitude operation equipment having same

Abstract

The invention provides a flexible pipe line conveying device. The flexible pipe line conveying device comprises five stages of guide supports and two stages of drag chains; a second guide support, a third guide support, a fourth guide support and a fifth guide support are all accommodated in a first guide support; the second guide support can slide relative to the first guide support; the third guide support can slide relative to the second guide support; the fourth guide support and slide relative to the third guide support; the fifth guide support is arranged in the fourth guide support and can slide relative to the fourth guide support; one end of the first drag chain is arranged on the first guide support, the other end of the first drag chain is arranged at the rear end of the third guide support; and one end of the second drag chain is arranged on the front portion of the third guide support, and the other end of the second drag chain is arranged at the rear end of the fifth guide support. The invention further provides aerial work equipment, the aerial work equipment adopts the flexible pipe line conveying device, accordingly the pipe line is better protected, internal spaces of the guide supports are saved, and the structure is compact.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, and in particular to a telescopic pipeline conveying device and high-altitude operation equipment having the same. Background technique [0002] Telescopic arm aerial work equipment is a product that serves mobile aerial work such as aerial work, equipment installation, and maintenance in various industries. The telescopic boom of the telescopic boom aerial work equipment changes its length through the telescopic mechanism to adapt to different working conditions. [0003] Telescopic boom aerial work equipment needs to transmit hydraulic power and electrical control signals to the actuator at the top of the boom or the control box of the work column through pipelines. Since the working height of this kind of equipment is generally above 30 meters, the pipeline transportation is affected by various factors such as wind force, pipeline weight, and the deflection of the arm body itsel...

AI Technical Summary

Problems solved by technology

[0005] This drag chain mechanism can realize such long-span and long-stroke pipeline transportation, but it is more suitable for telescopic arms with fewer segments, because as the number of telescopic arms increases, the thickness of the drag chain mechanism will increase significantly , and because the pipelines are distributed in an "S" shape in each tow box and tow chain, considering the deflection of the pipeline and tow chain, the design of the tow chain mechanism must be relatively large

Therefore, this towline mechanism has poor economy and takes up a lot of space.
