Description

TECHNICAL FIELD

[0001] The application relates to a measuring tool for a stacker-reclaimer component and belongs to the technical field of ring rail measurement of stacker-reclaimers. BACKGROUND

[0002] The stacker-reclaimer is widely used in bulk cargo wharfs, yards, power plants and other bulk cargo unloading scenes, and is mainly composed of a walking mechanism, a rotating mechanism, a tilting mechanism, a cantilever mechanism, a bucket wheel mechanism and a tail car mechanism, wherein the rotating mechanism is mainly divided into a rotating trolley type and a rotating bearing type, and the present scheme is designed for the rotating trolley type stacker-reclaimer. The rotating mechanism is composed of a driving device, a rotating trolley, a rotating wheel, a rotating rail, a horizontal wheel, a ring rail and an anti-overturning device. The driving device drives the rotating wheel to rotate on the rotating rail to realize the rotating action of the stacker-reclaimer, and the horizontal wheel rotates along the ring rail to prevent the rotating wheel from separating from the rotating rail. The ring rail will deform due to long-term extrusion by the horizontal wheel, so that the rotating wheel deviates from the rotating rail. The method for measuring the ring rail of the stacker-reclaimer is to use theodolites, laser range finders and other equipment to find the center of the ring rail and then to confirm the deformation of each point. However, because there are a large number of steel structures such as hoppers and horizontal wheel legs in the middle of the ring rail, the actual center cannot be accurately measured, resulting in inaccurate measurement results. In addition, in addition to the measurement, there is also a lack of operator's subjective perception of the size, and a lack of adaptability to different rails.

[0003] In order to solve the above problems, the application designs a ring rail measuring tool for a stacker-reclaimer, which measures the distance between the ring rail and the rotating rail in sections, finally obtains the relative deformation of the ring rail, and then repairs the ring rail according to the measurement results, so that the distance between the entire ring rail and the rotating rail is within a reasonable range, and finally the rotating wheel can normally operate on the rotating rail.
