Method for measuring length of support leg of crane based on light wave principle

Abstract

The invention discloses a method for measuring length of a support leg of a crane based on a light wave principle. The method comprises the following steps of measuring the length of a horizontal support leg, judging the state, limiting, and alarming, so as to measure the length of the movable support leg of the crane, thereby calculating the operation property of the crane under the current asymmetric working condition and the operation space of the current load. The method has the advantages that the structure is simple, and the effect is obvious; a light wave distance measuring device is used for replacing the traditional pull line distance measuring method, so that the accuracy in measuring is effectively improved; the influence by environment is little, and the reliability is better;the cost is lower than the cost of the pull line, and the service life is prolonged.

Description

technical field [0001] The invention relates to a method for measuring the length of outriggers for a crane based on the principle of light waves, and belongs to the technical field of engineering machinery. Background technique [0002] When the crane is working on the construction site, it often encounters the situation that there is insufficient space for the vehicle to expand. In order to meet the needs of the operation, a new working condition (asymmetrical outrigger working condition) has been developed. When the crane is close to an obstacle, some movable outriggers cannot be stretched out or cannot be fully extended. In asymmetric working conditions, the working performance and the working space of the current load can be automatically calculated according to the length of the crane’s outriggers to ensure safe completion. construction tasks. In order to ensure that the vehicle can work safely and reliably, the working condition monitors the accurate outrigger length...

AI Technical Summary

Problems solved by technology

The rope-drawing type is affected by the stretching and vibration of the outriggers, resulting in uneven winding and inaccurate values; the reel return spring is easy to get stuck, and the cable is easy to be broken; the device is large and difficult to install; the wire rope is directly exposed, and it is easy to adhere to dust. , the steel wire rope is pulled out, the recovery resistance is large, the coiled rope is uneven, it is easy to get stuck, and the outrigger is forced out and the steel wire rope is easily broken
