Aerial work platform and adjustable chassis counterweight mechanism thereof

Abstract

The invention discloses an adjustable chassis counterweight mechanism which comprises a chassis. The balancing weight is movably arranged on the chassis; the driving part is arranged on the chassis and is used for driving the balancing weight to reciprocate along the width direction of the chassis; the first angle sensor is used for detecting the inclination angle of the chassis relative to the ground; the second angle sensor is used for detecting the amplitude variation angle of the cantilever crane relative to the chassis; and the controller is in signal connection with the control ends of the first angle sensor, the second angle sensor and the driving part and is used for calculating the target moving distance of the balancing weight relative to the center of the width direction of the chassis through a preset formula and controlling the driving state of the driving part on the balancing weight according to the target moving distance. The gravity center position of the chassis is adjusted through the controller, so that the aerial work platform tends to be in a moment balance state, and the backward tilting stability can be improved on the basis that the amplitude variation angle of an arm frame does not need to be reduced. The invention further discloses the aerial work platform which has the beneficial effects mentioned above.

Description

technical field [0001] The invention relates to the technical field of engineering equipment, in particular to an adjustable chassis counterweight mechanism. The invention also relates to an aerial work platform. Background technique [0002] Aerial work platform (Aerial work platform) is a product that serves various industries such as aerial work, equipment installation, maintenance and other mobile aerial work. According to the difference of structural characteristics, aerial work platforms mainly include boom aerial work platforms, scissor aerial work platforms, trailer aerial work platforms, off-road aerial work platforms, cylinder-type aerial work platforms, spider aerial work platforms, etc. [0003] Taking the boom-type aerial work platform as an example, this kind of aerial work platform mainly includes three parts: chassis, turntable and boom. Among them, the chassis is usually equipped with tires, tracks, etc. to realize the walking function. The turntable is s...

AI Technical Summary

Problems solved by technology

In the prior art, the forward tilting stability can be improved by shortening the length of the jib, while the backward tilting stability can only be improved by limiting the luffing angle of the jib

However, if the luffing angle of the jib is lowered, it will be difficult to meet the design value for the reclining working height of the whole machine, and the performance of the whole machine will not meet the standard

Generally, among the various performance indicators of the aerial work platform, the reduction in the horizontal extension length of the whole machine is acceptable. However, if the working height of the whole machine is reduced due to the reduction of the boom luffing angle, it will directly lead to the quality of the whole machine. unqualified
