Abstract

The invention discloses an automatic tensioning device and a rope body length measuring device, and relates to the technical field of engineering machinery. It solves the technical problem in the prior art that the meshing gap between the worm gear and the worm is relatively large, resulting in relatively large measurement errors. The automatic tensioning device includes a connecting seat of the tensioning part, an elastic force device, a movable connection mechanism and a fixed seat body, and the connecting seat of the tensioning part can move from an initial position to a predetermined position relative to the fixed seat body; The elastic force exerted by the elastic device between the connecting seat of the tensioning component and the fixed seat body can move the connecting seat of the component to be tensioned from the initial position to a predetermined position. The rope length measuring device includes a reel, a worm wheel, a worm, a rotary potentiometer, a housing and an automatic tensioning device provided by the invention. The invention is used for reducing the measurement error of the length of the wire rope.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an automatic tensioning device and a rope body length measuring device provided with the automatic tensioning device. Background technique [0002] In recent years, the degree of industrial automation has become higher and higher, and sensing technology has developed rapidly, and the role of sensors cannot be ignored. Automatic control is inseparable from sensors, and precise automatic control is inseparable from high-precision, high-reliability sensors. The cable length sensor is widely used in the construction machinery industry to measure the length of the boom, the telescopic distance of the outrigger, etc., and its own performance affects the performance and image of the whole machine product to a certain extent. [0003] like figure 1 As shown, the existing wire rope length measuring device (or claim: stay wire length sensor) comprises wire rope reel 11, wor...
