Description

Technical Field

[0001] This utility model relates to a folding hoisting tool and a cutter head for a cutter suction dredger. Background Technology

[0002] Currently, the most common method used in China for cutterhead hoisting operations is to weld temporary lifting lugs. This method requires welding multiple additional lifting lugs onto the cutter arm to facilitate hoisting using a crane.

[0003] This method involves a complex process, requiring welding, hoisting, and cutting, and it is not feasible to operate on a ship, presenting significant limitations. After hoisting, the lifting lugs need to be cut to restore the cutter head to its original position, a process that may damage the cutter head itself.

[0004] Therefore, a foldable hoisting tool and a cutter head for a cutter suction dredger are proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the existing defects and provide a foldable hoisting tool and cutterhead for a cutter suction dredger, which meets the operational requirements of cutterhead hoisting, greatly reduces the difficulty of cutterhead hoisting operations, and improves production efficiency.

[0006] The technical solution to achieve the above objective is: a folding hoisting tool, including a shackle, a housing, a locking block, and a locking block limiting assembly;

[0007] The left end of the housing is connected to the shackle, and the right end of the housing has a square groove. The locking block is rotatably connected in the square groove through a first pin. A through groove is provided inside the housing, and the locking block limiting component is disposed in the through groove.

[0008] Preferably, the locking block assembly includes a pull rod, a connecting rod, and a locking rod; the pull rod is located at the left end of the through groove and is rotatably connected to the through groove via a second pin; the right end of the pull rod is movably connected to the connecting rod via a third pin; the right end of the connecting rod is movably connected to the locking rod via a fourth pin; and the right end of the locking rod passes through the outer shell and connects to the locking block.

[0009] The two ends of the card block are provided with limiting grooves that are adapted to the locking rod.

[0010] A cutter head for a cutter suction dredger based on a folding hoisting tool includes a cutter body, wherein a hoisting hole is provided on the cutter wall of the cutter body.

[0011] The diameter of the lifting hole is larger than the diameter of the outer shell.

[0012] The beneficial effects of this utility model are: This foldable lifting tool and cutter suction dredger cutter head can meet the operation requirements of cutter head lifting by installing a lifting tool on the cutter head, greatly reducing the difficulty of cutter head lifting operation and improving production efficiency.

[0013] By setting lifting holes on the cutter head and using clamps to fix the lifting device, the cutter head can be lifted without additional welding or cutting operations, simplifying the cutter head lifting process and increasing the convenience and efficiency of the cutter head lifting operation.

[0021] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, a folding hoisting tool includes a shackle 1, a housing 2, a locking block 3, and a locking block limiting assembly; the left end of the housing 2 is connected to the shackle 1, and the right end of the housing 2 has a square groove 4, and the locking block 3 is rotatably connected to the square groove 4 through a first pin 5; a through groove 6 is provided inside the housing 2, and the locking block limiting assembly is disposed in the through groove 6.

[0024] Specifically, the locking block assembly includes a pull rod 7, a connecting rod 8, and a locking rod 9. The pull rod 7 is located at the left end of the through groove 6 and is rotatably connected to the through groove 6 via a second pin 12. The right end of the pull rod 7 is movably connected to the connecting rod 8 via a third pin 10. The right end of the connecting rod 8 is movably connected to the locking rod 9 via a fourth pin 11. The right end of the locking rod 9 passes through the outer shell 2 and connects to the locking block 3. The two ends of the locking block 3 are provided with limiting grooves 15 that are adapted to the locking rod 9.

[0025] A cutterhead for a cutter suction dredger based on a folding lifting tool includes a cutter body 13, on which a lifting hole 14 is formed. The diameter of the lifting hole 14 is larger than the diameter of the outer shell 2.

[0026] Specifically, during installation, the outer casing 2 is inserted into the lifting hole 14 of the cutter body 13, and the pull rod 7 is pulled outward. The pull rod 7 rotates around the second pin 12 and drives the connecting rod 8 to move, thereby driving the locking rod 9 to move outward. The locking rod 9 moves out of the limiting groove 15 of the locking block 3. The locking block 3 is rotated, and the locking block 3 locks the lifting hole 14. The crane is connected to the shackle 1 to lift the auger.

[0027] Specifically, during disassembly, rotate the locking block 3 so that the limiting groove 15 of the locking block 3 is aligned with the guide hole of the outer shell 2, push the pull rod 7 inward, and the pull rod 7 rotates in the opposite direction to drive the connecting rod 8 to move, thereby driving the locking rod 9 to move inward. The locking rod 9 extends into the limiting groove 15 of the locking block 3 to complete the locking, and then moves out of the outer shell 2 from the reamer hoisting hole 14 to complete the disassembly.

[0028] This folding lifting tool and cutter suction dredger cutter head can meet the operational needs of cutter head lifting by installing lifting tools on the cutter head, greatly reducing the difficulty of cutter head lifting operations and improving production efficiency.

[0029] By setting lifting holes on the cutter head and using clamps to fix the lifting device, the cutter head can be lifted without additional welding or cutting operations, simplifying the cutter head lifting process and increasing the convenience and efficiency of the cutter head lifting operation.

[0030] Cutter suction dredgers are crucial equipment for waterway dredging. To ensure dredging efficiency, the cutter head needs to be hoisted for maintenance. Therefore, a convenient hoisting method can significantly improve the efficiency of dredging operations. This folding hoisting tool will greatly enhance the convenience and efficiency of hoisting the cutter head of a cutter suction dredger.
