[0002] At present, the mud nozzle at the end of the mud pipeline is generally not equipped with an orienting device or a buffer device, so the ejected mud head changes with the change of the working pressure and mud density in the pipeline, and the mud landing point cannot be determined and changes greatly. accumulation within a certain range
And sometimes due to the excessive impact force of the nozzle mud, it is easy to cause accidental injury.

The invention discloses a mud nozzle directional cushion rubber ring chain installed at the end of a mud deliver pipe used for dredging construction. The rubber ring chain comprises a group of arc-shaped rubber rings and inter-ring connecting pieces, wherein the group of rubber rings is connected together through the inter-ring connecting pieces. Each rubber ring comprises an arc-shaped metal frame, wear-resistant rubber materials, arc-shaped wear-resistant metal sheets and steel wire ropes. Metal hooks and circular metal rings are arranged on the metal frame. The arc-shaped wear-resistant metal sheets adaptive to the arc-shaped metal frame are fixed on the metal hooks. The two ends of each steel wire rope are fixed through the circular metal rings and are interwoven with the arc-shaped wear-resistant metal sheets to form a net. The lower part of the metal frame, the metal hooks, the circular metal rings, the arc-shaped wear-resistant metal sheets and the steel wire ropes are embeddedin the wear-resistant rubber materials. Screw holes connected with the adjacent rubber rings are arranged at the upper part of the metal frame. The invention has the advantages that the mud nozzle directional cushion rubber ring chain has a directional function and a cushion function on the sprayed mud, the lift of the mud at the nozzle is limited within a certain range, the mud spray direction can be controlled, the impact force of the mud can be cushioned and the accidents are reduced.
Description
technical field [0001] The invention relates to a directional buffer device for a mud nozzle at the end of a mud delivery pipeline in dredging construction. Specifically, it is a directional buffer rubber ring chain installed at the mud nozzle at the end of the mud pipeline. Background technique [0002] At present, the mud nozzle at the end of the mud pipeline is generally not equipped with an orienting device or a buffer device, so the ejected mud head changes with the change of the working pressure and mud density in the pipeline, and the mud landing point cannot be determined and changes greatly. accumulate within a certain range. And sometimes because the impact force of the nozzle mud is too large, it is easy to cause accidental injury accidents. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the purpose of the present invention is to provide a mud spout directional buffer rubber ring chain. The ring chain is flexib...
