Description

Technical Field

[0001] This utility model relates to the field of river dredging technology, and more specifically, to a dredging device for easy maintenance using a cutter suction dredging method. Background Technology

[0002] Dredging of urban river and lake bottom sediments is a crucial aspect of urban water environment management, and its construction quality directly impacts the success or failure of the remediation effort. Traditional dredging methods involve harsh working environments, significant ecological damage to bottom sediments, and a high risk of secondary pollution during construction. They also have long construction cycles, are heavily influenced by weather conditions, and require the construction of cofferdams and treatment storage areas, often limiting their implementation in urban environments. In contrast, the environmentally friendly integrated dredging and dewatering technology effectively ensures dredging depth and location, reduces secondary pollution, and utilizes pipelines to transport sludge to dewatering and drying plants, achieving integrated dredging, treatment, and disposal, thus achieving the goals and effects of environmentally friendly dredging. A river dredging vessel is a dredging equipment consisting of a carrier, sludge removal device, slurry preparation device, and sludge storage device. Maintenance of cutter suction dredging vessels requires close attention to core equipment such as the cutter system, hydraulic system, and delivery pump. Regular inspection and maintenance are crucial. The cutter head is often located at a certain distance from the end of the hull, making it difficult for workers to access the side of the cutter head during maintenance, thus affecting the convenience of maintenance. Therefore, we propose a cutter suction dredging device that is easy to maintain. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a dredging device for river channels that is easy to maintain.

[0004] To solve the above problems, this utility model adopts the following technical solution: a maintenance-friendly cutter suction dredging device for river dredging, comprising a river dredging hull, a swing frame at one end of the hull, a reamer at one end of the swing frame, a suction pipe below the swing frame, movable slots on both sides of the hull, and mounting slots on both sides of the hull. The inner cavities of the two movable slots are rotatably connected to screws via bearings. The inner cavities of the two mounting slots are fixedly installed with first brake reduction motors.

The ends of the two L-shaped brackets extend to both sides of the hull and are provided with mounting chambers. The inner cavities of the two mounting chambers are fixedly installed with second brake reduction motors. The output shafts of the second brake reduction motors extend to the outside of the L-shaped brackets and are fixedly connected to foot pedals. Auxiliary maintenance mechanisms are provided on the two foot pedals.

[0005] As a preferred embodiment of this utility model, the two auxiliary maintenance mechanisms include sliding grooves respectively disposed on two pedals, and telescopic plates are slidably connected to the inner cavities of the two sliding grooves. One telescopic plate extends to the outside of the pedal and is provided with an insert block, and the other telescopic plate extends to the outside of the pedal and is provided with a slot. Fixing holes are provided on both sides of the inner cavity of the slot, and a screw hole is provided on the insert block. A wing screw is threaded into the inner cavity of the screw hole.

[0006] In a preferred embodiment of this utility model, two sliding rods are fixedly sleeved in the inner cavity of the movable groove, and the sliding rods are movably sleeved with the L-shaped bracket.

[0007] As a preferred embodiment of this utility model, a telescopic hose is fixedly connected to the inner wall of the movable groove, the end of the telescopic hose is connected to the end of the L-shaped bracket, and the telescopic hose is sleeved on the outside of the screw.

[0008] As a preferred embodiment of this utility model, a first protective door is hinged to the outside of the inner cavity of the mounting groove, and a second protective door is hinged to the outside of the inner cavity of the mounting chamber.
