Abstract

The invention relates to the field of engineering machinery, and discloses a rope body length measuring device and a measuring method. The measuring device for the length of the rope body comprises: a reel for winding the rope; a trigger gear fixed at the center of the reel; a reduction gear meshed with the trigger gear; a second rotary potentiometer with a fixed axis for measuring a first angle showing the rotation angle of the trigger gear, wherein the second rotary potentiometer is a circular rotary potentiometer; The fixed first rotary potentiometer is used to measure the second angle showing the rotation angle of the reduction gear. The invention uses a double potentiometer to measure the length of the rope body, which can correct the wear and tear caused by the use of the trigger gear and the reduction gear, and improper installation. Measuring errors caused by intermittent meshing caused by other reasons.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a rope body length measuring device and a measuring method. Background technique [0002] In recent years, with the improvement of automation requirements in the field of construction machinery, the rope length measuring device (also called length sensor) that can automatically measure the length of the boom, the telescopic distance of the outrigger, etc. has also received more and more attention. The performance of the machine affects the performance and image of the whole product to a certain extent. [0003] figure 1 It is a structural schematic diagram of a single potentiometer rope length measuring device in the prior art. Such as figure 1 As shown, the single potentiometer rope body length measuring device includes a reel 1 (the rope body, such as a steel wire rope, is wound on the reel 1), fixed on the center of the reel 1 (with a radius of R). The trigger gear 2 a...
