Description

Technical Field

[0001] This invention relates to the field of underwater foundation construction equipment technology, specifically a pile driver for a piling vessel. Background Technology

[0002] In the construction of ports, bridges, water conservancy projects and other water-based foundation construction, pile driving vessels are essential key equipment. They are mainly used to drive various types of piles into the underwater foundation to form a stable foundation structure.

[0003] In the prior art, such as the "Multi-functional Pile Driving Vessel" with patent application number CN201010542789.5, a hull is included, on which a crane and a superstructure are mounted. A cylindrical body is located at the stern of the hull, with a rotating chassis on the cylindrical body. An A-frame is mounted on the rotating chassis, and a boom is connected to the A-frame. A wire rope connects the A-frame and the boom. A vertically placed shelf for supporting the boom is located at the front of the hull, and a pile hammer is located below the front of the boom. This invention has the advantages of simple structure, ease of use, and high work efficiency.

[0004] Existing pile driving vessels use traditional mechanical pile-holding equipment, which relies on manual measurement and control during the pile driving process. This makes it difficult to achieve real-time precision control throughout the entire process, resulting in lower construction efficiency. In complex aquatic environments, such as shallow waters, areas with rapid currents, or waters with complex geological conditions, it is difficult to achieve accurate positioning, which can easily lead to large deviations in the pile driving position and affect the construction quality. To address these issues, a pile-holding device for pile driving vessels is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pile-driving vessel pile gripper to solve the problems mentioned in the background art, such as the difficulty in achieving precise positioning, low pile driving efficiency, difficulty in real-time control of the pile driving process, and large deviations in the pile driving position when operating in complex aquatic environments, such as shallow waters, areas with rapid currents, or waters with complex geological conditions, which easily lead to large deviations in the pile driving position and affect the construction quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pile gripper for a pile driving vessel, comprising a pile gripper mechanism, wherein a clamping mechanism is symmetrically arranged at one end of the pile gripper mechanism for clamping and stabilizing the pile foundation, and telescopic adjustment mechanisms are movably installed on both sides of the pile gripper mechanism, one end of which is movably connected to the outside of the clamping mechanism; active adjustment mechanisms are symmetrically arranged on the two clamping mechanisms. The pile gripper mechanism is equipped with an attitude monitoring system, which includes GNSS antennas arranged on both sides of the pile gripper platform structure, laser rangefinders symmetrically arranged vertically at the front end of the pile gripper mechanism, tilt sensors on the side of the pile gripper platform, and a data processing host.

[0007] The pile gripper mechanism is equipped with an active adjustment mechanism for real-time adjustment of the pile foundation based on feedback data from the data processing host. The active adjustment mechanism includes an active adjustment cylinder, one end of which is equipped with a pressure-sensing guide roller.

[0008] Preferably, the telescopic adjustment mechanism includes a telescopic cylinder, a connecting seat is fixedly connected to the side of the telescopic cylinder, and a second rotating seat is provided in the middle of the telescopic cylinder. The second rotating seat is symmetrically installed on both sides of the pile gripper mechanism.

[0009] Preferably, one end of the telescopic cylinder is provided with a third rotating seat, and one end of the third rotating seat is connected to the outside of the clamping mechanism.

[0010] Preferably, the clamping mechanism includes a gripper, one end of which is connected to a first rotating seat, and the first rotating seat is symmetrically and fixedly installed at one end of the pile gripper mechanism.

[0011] Preferably, the other end of the active regulating cylinder is connected to a signal control line, and pile foundations are provided between the plurality of pressure sensing guide rollers.

[0012] Preferably, the top of the pile driver mechanism is provided with a data processing host and a control mechanism, and the control mechanism is located on the side of the data processing host.

[0013] Preferably, the control mechanism includes a hydraulic power control station, on which control pipelines are fixedly connected, and the control pipelines are distributed on the side of the pile gripper mechanism.

[0014] Preferably, a GNSS antenna is symmetrically arranged at the other end of the pile gripping mechanism, an angle sensor is arranged on the side of the pile gripping mechanism, and a video signal acquisition device is arranged at one end of the pile gripping mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, the pile gripper mechanism provides a mounting platform, facilitating the installation of multiple positioning auxiliary devices. By symmetrically arranging the grippers at one end of the pile gripper mechanism, it is convenient to clamp the pile foundation and perform auxiliary positioning operations. The telescopic cylinders are symmetrically and movably installed on both sides of the pile gripper mechanism via the second rotating seat, and connected to the hydraulic control circuit via the connecting seat, facilitating the control of the telescopic cylinders for extension and retraction adjustment. The third rotating seat is connected to the grippers, allowing the grippers to open and close during the extension and retraction adjustment process, facilitating the clamping operation of the pile foundation and enabling positioning.

[0017] 2. In this invention, a first rotating seat is provided at the connection between the gripper and the pile-holding mechanism, ensuring stable installation of the first rotating seat and facilitating stable rotation to achieve the gripping function.
