Abstract

The invention discloses a telescopic arm telescopic control system, method and crane. The telescopic boom telescopic control system includes: a working condition detection device and a controller. Wherein, the working condition detection device detects the arm position and working condition data of the telescopic arm, and transmits the arm position and the working condition data to the controller; the controller determines the current value according to the arm position and the working condition data , and output the current of the current value to the actuator to execute the extension or retraction of the telescopic arm. The invention realizes determining different telescopic control currents according to different telescopic working conditions.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a telescopic arm telescopic control system, method and crane. Background technique [0002] The single-cylinder bolt crane is a crane that realizes the telescopic arm telescopic function through the combined action of the telescopic oil cylinder, the arm pin and the cylinder pin. figure 1 It is a schematic diagram showing the structure of the telescopic arm of the single-cylinder bolt crane in the prior art. Such as figure 1 As shown, the telescopic arm includes: basic arm 11, two-section arm 12, three-section arm 13, four-section arm 14, five-section arm 15, telescopic oil cylinder 10, arm pin 111, arm pin hole 112, cylinder pin 101, cylinder pin hole 102 etc. [0003] The single-cylinder latch device located in the telescopic boom of the crane can assist the telescopic cylinder to realize the telescopic boom of the crane. It mainly consists of a cylinder pin, an arm pin,...
