[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

Embodiment Construction
[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0049] refer to figure 1 , is a bucket wheel dredger with a positioning pile lifting device disclosed in the present invention, including a hull 1, a buoyancy chamber 2, a bucket wheel suction system, a first positioning pile 3, a second positioning pile 301 and a lifting structure 4 (see Image 6 ). The buoyancy chamber 2 is a hollow cabin body, which is fastened on two opposite long sides of the hull 1 by chains to ensure the buoyancy of the hull 1, so that the hull 1 can withstand greater pressure on the water surface. When encountering a narrow area, the buoyancy chamber 2 can be removed from the hull 1, so that the hull 1 can move on the river more flexibly.
[0050] refer to figure 1 and figure 2 , the bucket wheel suction system is located at the bow, and the bucket wheel suction system includes a dredging bucket wheel 91 and a bucket wheel cabin...

The invention relates to a bucket-wheel-type dredger, in particular to a bucket-wheel dredger with a positioning pile lifting device. The dredger comprises a dredger body, a buoyancy cabin, a first positioning pile and a lifting structure, wherein the lifting structure comprises a positioning frame and a lifting frame, a set of opposite side walls of the positioning frame are fixedly connected with guide rods correspondingly, the lifting frame comprises a lifting plate and a lifting hook, the lifting plate sleeves the guide rods in a sliding manner, a mounting opening is formed in the bottom of the lifting plate, a hooking groove is formed in the first positioning pile, a tightening opening is formed in the lifting plate, and a guide hole is formed in one side of the tightening opening; atraction rod slides in the guide hole, one end of the traction rod is fixedly connected with an abutting plate, an ejection pressure spring is sandwiched between the abutting plate and the side wall of the lifting plate, the lifting hook is connected with a tightening steel rope, and the tightening steel rope is connected to the traction rod; and a lifting oil cylinder is connected to the side wall of the positioning frame, and a telescopic rod of the lifting oil cylinder is fixedly connected to the lifting plate. According to the dredger, pile setting and pile pulling are carried out in a mechanical mode, and the dredger has the advantages of saving manpower and improving the pile setting 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...
