Embodiment Construction

[0031] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0032] In this embodiment, the boom with a horizontal bar pin type telescopic system is taken as an example to describe the calibration system of the boom telescopic speed. Of course, the application of the calibration system for the boom telescopic speed of the present invention is not limited to the crane with a horizontal bar pin type telescopic system. arm. The boom of this embodiment includes a multi-section telescopic boom, and the oil cylinder can be connected to any section of the telescopic boom, and the oil cylinder is used to extend and retract the telescopic boom connected thereto to the base boom.

[0033] Such as figure 1 As shown, the calibration system for the telescopic speed...

Abstract

The invention provides a calibration system for the extending and retracting speed of a lifting arm and a calibration method. The lifting arm comprises a plurality of sections of extending and retracting arms. The calibration system comprises a speed detecting device and a control unit, wherein the speed detecting device is used for detecting the extending and retracting speed of an oil cylinder or the extending and retracting arms of the lifting arm; the control unit is connected with the speed detecting device, is used for receiving the extending and retracting speed detected by the speed detecting device, adjusting an extending and retracting control value according to the extending and retracting speed so as to enable the extending and retracting speed of the oil cylinder or the extending and retracting arms to reach the target speed, and using the extending and retracting control value corresponding to the target speed as a calibration value. By application of the technical scheme, the problems of large workload and low efficiency in the prior art are effectively solved.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a calibration system and a calibration method for boom telescoping speed. Background technique [0002] In the prior art, in the crane industry, products with six-section booms and more than multi-section booms generally adopt single-cylinder bolt telescopic mechanisms. The single-cylinder bolt telescopic mechanism is not as flexible as the traditional double-cylinder rope-row telescopic mechanism, but the overall weight of the boom is lighter and the lifting capacity is significantly improved, so it has been widely used in all-terrain cranes. There are two main methods of single-cylinder bolt telescopic control, automatic telescopic and manual telescopic. The automatic telescopic operation is simple, as long as the target arm length is set, press the automatic telescopic switch, and the boom will automatically retract to the target arm length. [0003] The automatic telescopic process ca...
