Description

Technical Field

[0001] This utility model relates to the field of dredging technology, specifically to a dredging vessel positioning pile lifting device. Background Technology

[0002] Dredgers are responsible for clearing silt from waterways and rivers to allow other vessels to pass smoothly. They are also powerful tools for land reclamation. Types include cutter suction dredgers and trailing suction hopper dredgers. The smooth flow of waterways depends entirely on dredgers.

[0003] A search revealed Chinese Patent Publication No. CN207725574U, which discloses a dredging vessel positioning pile lifting device, belonging to the field of dredging vessel technology. The device includes a positioning pile installed at the rear of the dredging vessel, with a pointed tip at the bottom of the positioning pile. The positioning pile vertically penetrates the dredging vessel, and a positioning pile sleeve is installed on the top of the dredging vessel for the positioning pile to slide up and down. A rack is installed on the right side of the positioning pile, and a hydraulic motor is fixed on the dredging vessel. A gear is fixed at the output end of the hydraulic motor, and an opening groove is provided at the lower right end of the positioning pile sleeve, into which the gear extends and meshes with the rack. The gears and racks of this invention are made of corrosion-resistant materials with sufficient strength and rigidity. This positioning pile lifting device has the functions of positioning, lifting, and pressing piles. It achieves pile pressing positioning and is suitable for hard foundations such as silty clay, gravelly sand, weathered rock, and sandstone. It has the characteristics of reasonable design, compact structure, practicality, and excellent performance, and therefore has a good prospect for promotion and practical application. Although this application can solve the problem of fixing steel piles with steel wire ropes for lifting piles, the positioning pile falls by its own weight, and the friction between the steel wire rope and the positioning pile can easily damage the steel wire rope and cause the pile to slip, posing a safety hazard. However, using a single positioning pile for positioning is not only not stable enough, but also prone to generating large vibrations when lifting the pile and setting sail. Utility Model Content

[0022] Example:

[0023] Please see Figures 1-3A dredging vessel positioning pile lifting device includes a lifting structure 1 and an installation structure 2. Lifting structures 1 are installed on both sides of the installation structure 2. The lifting structure 1 consists of a fixed base 11 and positioning piles 13. A groove 111 is formed on the top of the fixed base 11. Limiting wheels 112 are installed on the side walls of both sides inside the groove 111. A connecting groove 113 is formed on the outer side of the groove 111. A power supply base 12 is installed around the top of the fixed base 11 around the groove 111. The positioning piles 13 are installed inside the groove 111. Deep-embedded nails 132 are installed at the bottom of the positioning piles 13, and a top seat 14 is installed at the top of the positioning piles 13. A lifting ring 15 is installed on the top of the top seat 14, and a connecting ring 16 is fitted on the lifting ring 15. A support rod 17 is installed on the top of the fixed seat 11 on one side of the groove 111. A limit ring 171 is installed on the top of the support rod 17. The positioning pile 13 can be moved up and down in the groove 111 by the limit rotation in the groove 111 on the fixed seat 11. The threaded groove 131 on the outer surface of the positioning pile 13 can greatly increase the friction between the limit wheel 112 and the positioning pile 13, which can prevent the positioning pile 13 from slipping. The deep-embedded nail 132 at the bottom of the positioning pile 13 can more firmly fix the positioning pile 13 in the silt.

[0024] Please see Figure 1 and Figure 3 The installation structure 2 consists of a base 21 and a control device 22. The control device 22 is installed on the top of the base 21, and a display screen 221 is installed on the outside of the control device 22. Several control buttons 222 are installed below the display screen 221. Motor seats 23 are installed on both sides of the top of the base 21, which are located on the control device 22. A drive motor 24 is installed on the outside of the motor seat 23. A mounting seat 26 is installed on the back of the motor seat 23. A winding wheel 25 is installed on the mounting seat 26. The lifting steel cable 251 in the limiting groove 252 on the outer surface of the winding wheel 25 can be connected to the connecting ring 16 through the limiting ring 171. The positioning pile 13 can be lifted by the lifting ring 15 on the top seat 14 through the connecting ring 16. The positioning pile 13 can be lowered by the reverse rotation of the winding wheel 25. This is used to assist the limiting wheel 112 in controlling the rise and fall of the positioning pile 13.

[0025] Please see Figures 1-2 The positioning post 13 is fixed in the groove 111 by the limiting wheel 112, and the limiting wheel 112 can drive the positioning post 13 to move up and down in the groove 111. Several threaded grooves 131 are opened on the outer surface of the positioning post 13. The grooves can greatly increase the friction between the limiting wheel 112 and the positioning post 13, and can prevent the positioning post 13 from slipping.

[0026] Please see Figure 3A rotating shaft 261 is mounted on the outside of the mounting base 26. A drive shaft 231 is mounted between the rotating shaft 261 and the motor base 23. The output end of the drive motor 24 is connected to the drive shaft 231. The drive motor 24 can drive the drive shaft 231 to rotate, thereby causing the rotating shaft 261 to drive the take-up wheel 25 to rotate on the mounting base 26.

[0027] Please see Figure 1 and Figure 3 The take-up reel 25 is inserted into the mounting base 26, and the rotating shaft 261 is inserted into the connection between the take-up reel 25 and the mounting base 26. A limit groove 252 is formed on the outer surface of the take-up reel 25, and a lifting steel cable 251 is sleeved inside the limit groove 252. The lifting steel cable 251 in the limit groove 252 on the outer surface of the take-up reel 25 is connected to the connecting ring 16 through the limit ring 171. The positioning pile 13 is lifted by the lifting ring 15 on the top seat 14 through the connecting ring 16, and the positioning pile 13 can be lowered by the reverse rotation of the take-up reel 25. This is used to assist the limit rotating wheel 112 in controlling the rise and fall of the positioning pile 13.

[0028] Please see Figure 1 and Figure 3 One end of the lifting cable 251 is wound in the limiting groove 252 on the outer surface of the take-up reel 25, and the other end passes through the limiting ring 171 and is fixedly connected to one end of the connecting ring 16. The lifting cable 251 is connected to the connecting ring 16 through the limiting ring 171, and the positioning pile 13 is lifted by the lifting ring 15 on the top seat 14 through the connecting ring 16.

[0029] Please see Figure 1 The mounting bases 11 are all fixedly installed on both sides of the base 21, which can be installed on the ship through the base 21, and the mounting bases 11 can improve the overall stability of the device.

[0030] Working principle: During use, the positioning pile 13 can be moved up and down in the groove 111 on the fixed base 11 by the limiting rotation. The threaded groove 131 on the outer surface of the positioning pile 13 greatly increases the friction between the limiting wheel 112 and the positioning pile 13, which can prevent the positioning pile 13 from slipping. The deeply embedded nail 132 at the bottom of the positioning pile 13 can more firmly fix the positioning pile 13 in the silt. The lifting steel cable 251 in the limiting groove 252 on the outer surface of the winding wheel 25 is connected to the limiting ring 171. The positioning pile 13 is lifted by the lifting ring 15 on the top seat 14 via the connecting ring 16, and can be lowered by the reverse rotation of the winding wheel 25. This assists the limiting wheel 112 in controlling the rise and fall of the positioning pile 13. The positioning piles 13 on the two fixed seats 11 can work in cycles. When one positioning pile 13 is lifted, the other positioning pile 13 can be lowered. This not only better stabilizes the hull but also improves the efficiency of dredging. This device has a simple structure, is easy to use, and has better stability.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
