Dual-yoke type heavy steel pile trolley for cutter suction dredge

Abstract

The invention relates to a dual-yoke type heavy steel pile trolley for a cutter suction dredge, which comprises a ship hull, a steel pile, a walking oil cylinder, a track, a trolley main body structure, walking yokes and a cushioning device, wherein the rail is connected with the ship hull, one end of the waling oil cylinder is connected with the trolley main body structure, while the other end is connected with the ship hull, and the upper end of the cushioning device is connected with the trolley main body structure, while the lower end is contacted with the plane of the track. The dual-yoke type heavy steel pile trolley has the advantages of compact and reasonable structure, large bearing capacity and strong rail deformation adaptability. Walking rollers can adjust the position automatically according to the condition of the rail in the walking process to ensure that each walking roller contacts with the rail all the time and bears evenly, thus the service life of the walking rollers is prolonged effectively. By adopting the cushioning device, the walking rollers of a first walking yoke and a second walking yoke contact with the upper surface and the lower surface of the rail respectively; and when the outside wind wave force is large, the cushioning device can prevent the walking rollers from impacting the rail directly so as to play a role in cushioning.

Description

technical field [0001] The invention relates to a device in the technical field of marine engineering, in particular to a double-yoke type heavy-duty steel pile trolley for a cutter suction dredger. Background technique [0002] Modern large-scale cutter suction dredgers usually use a steel pile trolley system for shifting. The trolley system moves through the push and pull of the traveling cylinder, and sends an instruction signal through the trolley stroke to accurately control the forward distance, which can greatly save time and significantly improve production efficiency. [0003] After searching the literature of the prior art, it was found that Jiang Ruhong and others published "Design and Research of Large Cutter Suction Dredger Trolley System" on page 41 of the 3rd issue of "Ship Engineering" in 2007. The system principle and composition of the positioning device of the suction dredger trolley, among which the walking subsystem is composed of walking cylinders, fro...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned trolley system is generally suitable for construction conditions with small wind and waves. At this time, the track deformation is small, and the trolley system can fine-tune the height of the wheel center of the road wheel to adapt to the track deformation; The external force increases sharply, and the deformation of the track increases accordingly. The above-mentioned trolley system cannot adapt, and in severe cases, it may cause damage.
