Problems solved by technology

However, since the hydraulic oil in the hydraulic drive system is greatly affected by temperature, changes in temperature lead to changes in the viscosity of the hydraulic oil, thus resulting in changes in the output power of the hydraulic motor 16
This will cause the rotation speed of the hoisting mechanism to change under the condition that the driving current of the proportional solenoid valve 18 is kept the same

Abstract

A winching mechanism test platform is disclosed, and comprises a winching mechanism which comprises a hydraulic driving system for driving the winching mechanism, wherein the hydraulic driving system comprises a hydraulic motor and a proportional solenoid associated with the hydraulic motor. The test platform further comprises a rotate speed detector coupled with the winching mechanism for detecting the rotate speed of the winching mechanism and outputting corresponding rotate speed signals; a controller electrically coupled with the winching mechanism and configured to receive the rotate speed signal from the rotate speed detector and compare the detected rotate speed with preset standard one, to generate corresponding control signals according to the comparison result and output the control signal to the proportional solenoid so as to adjust the output power of the hydraulic motor by adjusting the openness of the solenoid to control the rotate speed of the winching mechanism to be matched with the standard rotate speed.

Description

technical field [0001] The invention relates to a control device and method for a hoisting mechanism and a hoisting mechanism test platform. Background technique [0002] The hoisting mechanism test platform is used to study and improve the problems of various hydraulically driven hoisting mechanisms on construction machinery, such as messy ropes, high friction, and difficulty in climbing floors. The hoisting mechanism test platform usually includes a hoisting mechanism, a bench and a control device. A gantry is similar to a crane, such as a tower crane. The winch mechanism is divided into motor frequency conversion drive type and hydraulic drive type. The hydraulic drive type winch mechanism is driven by a hydraulic drive system including a hydraulic motor. figure 1 A schematic diagram of such a hydraulic drive system is shown in . like figure 1 As shown, the hydraulic drive system mainly includes an oil tank 14 , a hydraulic motor 16 , a proportional solenoid valve 18 ...
