Real-time calibration device for rotation angle of cantilever of bucket wheel machine

Abstract

The invention discloses a real-time calibration device for the rotation angle of a cantilever of a bucket wheel machine, and belongs to the technical field of bucket wheel stacker reclaimers. The real-time calibration device comprises a bucket wheel machine mounting seat, a rotating seat is mounted on the bucket wheel machine mounting seat, and the cantilever is mounted on the rotating seat; the rotating seat is of a disc-shaped structure, an angle scale is embedded in the side of the upper surface of the bucket wheel machine mounting seat, an angle calibration rod is vertically arranged on the side wall of the rotating seat, a movable rod is arranged at the bottom end of the angle calibration rod in a penetrating mode, a shell cover is horizontally fixed to the bottom end of the movable rod, and a calibration groove is formed in one side of the top wall of the shell cover; a calibration groove is formed in the shell cover, the calibration groove is aligned with the angle ruler, a pair of pressing plates are horizontally arranged in the shell cover side by side and located on the two sides of the calibration groove respectively, and absorbent cotton blocks are arranged on the lower surfaces of the pair of pressing plates. The rotation angle real-time calibration device of the bucket wheel machine cantilever can visually judge whether the rotation angle of the cantilever deviates or not.

Description

technical field [0001] The invention belongs to the technical field of bucket wheel stackers and reclaimers, in particular to a real-time calibration device for the rotation angle of a bucket wheel cantilever. Background technique [0002] Bucket wheel stacker and reclaimer refers to a high-efficiency loading and unloading machine used for continuous conveying of both stacking and reclaiming materials in large dry bulk storage yards. It is composed of a belt conveyor arm that can tilt and swing horizontally and its front bucket wheel, frame, and running mechanism. The belt can run in both directions. When reclaiming materials, the bucket wheel reclaims the material and sends it out through the conveying arm, and when stacking, the main conveyor The delivered goods are sent to the yard via the conveying arm. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in this technology: in reality, with the lo...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that in the prior art, angle errors are prone to occur during the rotation of the cantilever (i.e. the conveying arm), but it is difficult for the operator to intuitively judge whether there is a deviation in the rotation angle of the cantilever, which in turn affects the retrieving and transferring of materials. A real-time calibration device for the rotation angle of the cantilever of the bucket wheel machine is proposed
