Abstract

The invention discloses a lifting rope swing angle detection device used for cranes, comprising at least one angle sensor (24) and a sleeve (22) coaxially sheathed outside a lifting rope (23), wherein, the angle sensor (24) is installed on the outer wall of the sleeve (22), and an anti-slide device is arranged between the sleeve (22) and a crane arm head (21) so as to prevent the sleeve (22) fromaxially rotating along the sleeve. Thus, the invention realizes the direct measurement of the lifting rope deflection angle, simplifies the structure of the detection device and ensures small occupation space; meanwhile, the anti-slide device arranged between the sleeve (22) and the crane arm head (21) prevents the crane arm head (21) from rotating along the vertical shaft of the crane arm head (21), so that the stability of the device detection coordinate system can be kept, and the detection accuracy of the device is improved. The invention also discloses a crane comprising the above lifting rope swing angle detection device.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a detection device for the deflection angle of a suspension rope used for a crane. The present invention also relates to a crane comprising the above-mentioned suspension rope deflection angle detection device. Background technique [0002] With the rapid development of my country's economic construction, construction machinery, especially cranes, are more and more widely used in various fields of economic construction. [0003] The hook is an important part of the crane and the most common type of spreader in the hoisting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of a pulley block and other components. During the lifting process of the crane, because the center of gravity of the hook and the center of gravity of the hoisted cargo are not on the same vertical line before the hook is hoisted, or the hoisting position is shifte...
