Abstract

The invention discloses a winch automatic controlling type three-section folding conveyor. The winch automatic controlling type three-section folding conveyor comprises three conveying arms, a main portal frame and a winch. The winch automatic controlling type three-section folding conveyor is characterized by further comprising a secondary portal frame I, a secondary portal frame II, a hydraulicoil cylinder, a limiting device I, a limiting device II and a steel wire rope, wherein the conveying arms are all of a trapezoidal truss type structure; the secondary portal frame I is hinged with a hinging hole in the big end of the second conveying arm, and the limiting device I is arranged on the hinging hole; the secondary portal frame II is hinged with a hinging hole in the small end of the second conveying arm, and the limiting device II is arranged on the hinging hole; the winch, the hydraulic oil cylinder and the main portal frame are mounted on a ship body. According to the winch automatic controlling type three-section folding conveyor, the conveying arms are long enough and are upwards turned over to be folded, and moreover, the hydraulic oil cylinder is not used, so that the load of a belt is decreased, the cost is reduced, and the mass of the conveying arms is reduced; the problems such as safety accident caused by forwards-shifted weight due to excessively high mass of the conveying arm can be solved, and thus the safety coefficient is increased.

Description

technical field [0001] The invention belongs to the field of conveyors, in particular to a three-section folding conveyor automatically controlled by a winch. Background technique [0002] Since the fixed conveying arms of self-unloading ships are easy to collide with bridges or ships, which may cause potential safety hazards, most of the current self-unloading ships use retractable non-fixed conveying arms. However, the following problems still exist in the current foldable conveyor arm: (1) The conveyor arm is folded downward, and the belt has a large negative margin; (2) Due to the limitation of the structural design, the structure is heavy, the cost is high, and the conveying length is limited; ( 3) The safety factor is not high, and the delivery arm is prone to breakage. [0003] 1) The patent document CN201310014167.9 discloses a hydraulically foldable conveying arm for a sand self-unloading ship. Its main technical scheme is: it consists of three-stage arm, four-bar...
