Problems solved by technology

[0003] In the related technology, when the empty cylinder of the crane stretches out to find the arm position, due to the rough processing of the boom slideway and the assembly error, the resistance of the telescopic oil cylinder running on the slideway is uneven, which leads to the vibration phenomenon when the empty cylinder is running

Abstract

The present disclosure relates to a control method of a crane and a telescopic oil cylinder, so as to solve the problems existing in related technologies. The crane includes: a telescopic oil cylinder, a telescopic oil cylinder controller, a pressure sensor connected to the telescopic oil cylinder controller, the pressure sensor is arranged on the oil inlet path of the extension cavity of the telescopic oil cylinder; the pressure sensor is used to detect The pressure information of the extension cavity; the telescopic oil cylinder controller is used to determine whether the telescopic oil cylinder is in a shaking state according to the pressure information, and increase the pressure on the telescopic oil cylinder when the telescopic oil cylinder is in a shaking state Control the current so that the telescopic oil cylinder speeds up the extension action, and reduce the control current to the telescopic oil cylinder when it is detected that the arm driven by the telescopic oil cylinder reaches the target position point, so that the telescopic oil cylinder slows down the extension action .

Description

technical field [0001] The present disclosure relates to the technical field of construction machinery, and in particular, to a control method for a crane and a telescopic oil cylinder. Background technique [0002] At present, the wheeled cranes used in the market mainly use a single-cylinder bolt telescopic mechanism to control the telescopic extension of the boom. [0003] In the related art, when the crane empty cylinder extends to find the arm position, due to rough processing of the boom slide and assembly errors, the resistance of the telescopic oil cylinder running on the slide is uneven, resulting in jitter when the empty cylinder is running. SUMMARY OF THE INVENTION [0004] The purpose of the present disclosure is to provide a crane and a telescopic oil cylinder control method to solve the problems existing in the related art. [0005] In order to achieve the above object, according to the first part of the embodiments of the present disclosure, a crane is prov...
