Bucket wheel dredger with spud lifting device

Abstract

The invention relates to a bucket wheel dredger, in particular to a bucket wheel dredger with a positioning pile lifting device, comprising a hull, a buoyancy chamber, a first positioning pile and a lifting structure, the lifting structure includes a positioning frame and a lifting structure A set of opposite side walls of the positioning frame are respectively fixedly connected with guide rods. The lifting frame includes a lifting plate and a lifting hook. The lifting plate slides and is set on the guiding rod. There is a hook slot on the pile, a tightening opening is opened on the lifting plate, and a guide hole is opened on one side of the tightening opening; a traction rod slides in the guide hole, and a collision plate is fixedly connected to one end of the traction rod. The side walls of the plates are interposed with ejection compression springs, the lifting hook is connected with a tightening steel rope, and the tightening steel rope is connected to the drawbar; the side wall of the positioning frame is connected with a lifting cylinder, and the telescopic rod of the lifting cylinder is fixedly connected to the lift plate. The invention adopts a mechanical method to lower piles and pull piles, and has the advantages of saving manpower and improving pile lowering efficiency.

Description

technical field [0001] The invention relates to a bucket wheel dredger, in particular to a bucket wheel dredger with a positioning pile lifting device. Background technique [0002] Bucket wheel dredger is a hull that travels on the sea or river to clean up river bed silt. With the rapid development of the domestic economy, the pace of urbanization is accelerating, and urban planning and construction are speeding up. Many urban domestic sewage and industrial sewage Untreated direct discharge leads to serious river silting, so bucket wheel dredgers are gradually playing an increasingly important role in the field of dredging. [0003] At present, the Chinese patent whose publication number is CN102409711A discloses a kind of urban small river channel dredging ship, which comprises a bridge frame positioned at the bow, a suction and discharge device positioned in the engine room of the hull, and a first positioning pile positioned at the stern. The A-frame connected to the hu...

[0005] However, due to the bulky volume of the first spud, it takes a lot of manpower to move the first spud to the hull support and wind the cable. In addition, in the process of moving the first spud and winding the cable Need to waste a lot of time, prolong the time of the whole piling, and have the disadvantage of poor piling efficiency, and there are obvious deficiencies
