CONTROL APPARATUS AND METHOD FOR HOISTING MECHANISM AND TEST PLATFORM FOR HOISTING MECHANISM

摘要

Disclosed is a test platform for a hoisting mechanism, which platform comprises a hoisting mechanism (20), the hoisting mechanism (20) comprising a hydraulic driving system for driving the hoisting mechanism (20), and the hydraulic driving system comprising a hydraulic motor (16) and a proportional solenoid valve (18) associated with the hydraulic motor (16). The test platform also comprises: a rotational speed detecting device (30) coupled to the hoisting mechanism, for detecting the rotational speed of the hoisting mechanism (20) and outputting a rotational signal indicating the rotational speed; a control device (40) electrically coupled to the rotational speed detecting device, the control device (40) being configured to receive the rotational speed signal from the rotational speed detecting device, compare the detected rotational speed and a predetermined standard rotational speed, generate a corresponding control signal according to the comparison result and output the control signal to the proportional solenoid valve (18) so as to regulate the output power of the hydraulic motor by means of adjusting the degree of opening of the proportional solenoid valve (18), and control the rotational speed of the hoisting mechanism so as to match the standard rotational speed, such that the rotational speed is not influenced by a temperature change of the hydraulic oil within the hydraulic driving system. Also disclosed are a control method and a control apparatus for a hoisting mechanism.
