Abstract

The invention discloses a two-section folding conveyer automatically controlled by a winch. The two-section folding conveyer automatically controlled by the winch is mounted on a ship and mainly consists of components and parts such as a second conveying arm of which one end is hinged with the ship, a first conveying arm of which the bottom end is hinged with the other end of the second conveyingarm, an auxiliary gantry which is hinged with a large-end hinging hole of the first conveying arm, a main gantry which is arranged on the ship, a hydraulic cylinder, and a winch. As a steel wire ropeis withdrawn and released by using the winch in the withdrawing and release process, the first conveying arm is folded up, and a redundant belt is reduced; in addition, no oil cylinder is used while the first conveying arm is unfolded and folded, so that the weight of the device self is reduced, the operation process is simplified, and the cost is lowered. The two-section folding conveyer has thecharacteristics of being simple in structure, light in device weight, good in security, low in cost and the like.

Description

technical field [0001] The invention relates to the technical field of conveying, in particular to a two-section folding conveyor automatically controlled by a hoist. Background technique [0002] Since the fixed conveying arms of self-unloading ships are easy to collide with bridges or ships, which will cause 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 down, and the belt has a large negative margin; (2) Due to the limitation of the structural design, the structure is heavy and the cost is high; (3) The safety factor If it is not high, the delivery arm is prone to breakage. In order to focus on solving the above problems, we have studied and improved the current self-unloading ship belt conveying device, and designed a new product of this patented technology. [0003] The following are some relevant existing...
