A long-distance heavy-duty drag chain supporting device

Abstract

A long-distance heavy-duty drag chain supporting device, including a support frame extending horizontally and horizontally for carrying the drag chain and a supporting mechanism for supporting the upper section of the drag chain. The supporting bracket on the frame, the supporting wheels set on the supporting bracket at intervals to support the bottom of the upper section of the drag chain, the rollers arranged on the supporting bracket and located in the steering ring section of the drag chain, when the drag chain turns to the ring section The lateral movement can drive the roller to move laterally, thereby driving the support bracket to move laterally so that the upper section of the towline is always supported on the supporting roller. The invention has the advantages of simple structure and strong adaptability, and can effectively prevent the upper section of the towline from rubbing against the lower section of the towline. , prolong the service life of the drag chain.

Description

technical field [0001] The invention relates to the field of drag chains, in particular to a long-distance heavy-duty drag chain supporting device. Background technique [0002] The long-distance heavy-duty towline can be divided into three parts during the movement process, the lower section of the towline, the steering ring section of the towline and the upper section of the towline. The lower section of the towline is laid flat on the supporting frame of the towline. Due to the load, it is stacked on the top of the lower section of the towline, while the turning ring section of the towline forms a circular closed shape. Since the upper section of the towline is stacked on the lower section of the towline, the lower section of the towline will friction, the drag chain will be severely worn under heavy loads. For this reason, there are many solutions on the market, such as a full-stroke mobile support type heavy-duty drag chain disclosed by the publication number CN1587009A...

Problems solved by technology

[0002] The long-distance heavy-duty towline can be divided into three parts during the movement, the lower section of the towline, the steering ring section of the towline and the upper section of the towline. The lower section of the towline is laid flat on the supporting frame of the towline. Due to the load, it is stacked on the top of the lower section of the towline, while the turning ring section of the towline forms a circular closed shape. Since the upper section of the towline is stacked on the lower section of the towline, the lower section of the towline will friction, the drag chain will be severely worn in the case of heavy loads. For this reason, there are many solutions on the market, such as a full-stroke mobile support heavy-duty drag chain disclosed by the publication number CN1587009A. The movable supporting device between the upper part of the chain and the lower part of the towline prevents friction between the upper part of the towline and the lower part of the towline. The supporting device adopts a group of large-diameter rollers that move synchronously. The teeth and the roller set are composed of two connecting rods and multiple rollers. It is only suitable for towlines with a gap between two adjacent towline support plates, the gap is used to mesh with the teeth of the rollers, so it is only suitable for non-enclosed towlines, not closed towlines
