Description

Technical Field

[0001] The invention belongs to the field of pile-driving ships, and in particular relates to a pile-driving ship equipped with side positioning tooling and a use method thereof. Background Art

[0002] Traditional offshore pile positioning is to set up a theodolite or total station on the shore or on a fixed foundation, select a reference point and perform remote positioning control. The disadvantage of this solution is that the distance between the surveyor and the operator on the pile-driving ship will gradually increase with the progress of the construction. To a certain extent, the control accuracy and the efficiency of real-time communication will be significantly reduced. Traditional theodolite and total station positioning require surveyors to perform a series of calculations based on the measurement data to determine the current pile position. For surveyors, the work intensity is high, and because the pile-driving ship is constantly moving, the pile position calculated based on the measurement data is often inconsistent with the current pile position, resulting in repeated forward and backward and left and right movement of the pile-driving ship. Positioning accuracy is also affected by the workers' technical proficiency and their mastery of instrument use skills. There are large individual differences, and it is difficult to achieve a unified error standard. Due to the above reasons, the traditional pile positioning efficiency is low. When the area to be piled is too far from the shore, with a distance of more than ten or even dozens of kilometers, the traditional method is no longer applicable. The only way is to transfer the coordinates by reselecting the reference point or setting up a working platform, which will greatly reduce the construction accuracy, affect the construction efficiency, and increase the project cost.

[0003] However, the existing pile-driving ships have poor efficiency in positioning the piles, and various positioning tools are generally arranged on the outer side wall of the ship, which makes construction and maintenance inconvenient. Summary of the invention

[0004] In order to overcome the problems that the existing pile-driving boats have poor pipe pile positioning efficiency and various positioning tools are arranged on the outer side wall of the boat, resulting in inconvenient construction operation and maintenance, the present invention provides a pile-driving boat equipped with a side positioning tool and a method for using the same. The present invention arranges a support, a base and a base cylinder in the hull, and the operator can perform maintenance at any time. The truss assembly is connected through the base, and a pile gripper assembly is arranged on the truss assembly, so as to perform fast and effective positioning.

[0005] The technical solution adopted by the present invention is:

[0006] A pile-driving ship equipped with a side positioning tool comprises a control system, a hull assembly, a truss assembly, a support, a base and a base oil cylinder, wherein the truss assembly is multiple, one end of each truss assembly is connected to the corresponding base on the hull assembly, and the other end of the truss assembly extends outward from the hull assembly.

[0007] A pile gripper assembly is provided on the portion extending out of the hull assembly; the left and right ends of the base are slidably connected to the support, the base cylinder is provided on the hull assembly and connected to the base, the base cylinder controls the base to move in the support, and the base cylinder and the pile gripper assembly are respectively connected to the control system electrical signal.

[0008] The base includes a vertical support rod, a horizontal round rod and a cylinder connecting ear plate. The horizontal round rod is vertically arranged to the vertical support rod. The vertical support rod is located in the middle of the horizontal round rod. There are two horizontal round rods and they are arranged in parallel. Both ends of the horizontal round rod are inserted into corresponding supports. The base is arranged along the side.

[0009] The support comprises a bottom plate, a vertical plate and a round sleeve, wherein the round sleeve is connected to the bottom plate through the vertical plate.

[0010] The bottom plate is fixed on the hull assembly, the opening direction of the circular sleeve is the same as the direction of the horizontal round rod of the base, and the two ends of the horizontal round rod are located in the corresponding circular sleeves on the support.

[0011] The truss assembly includes a top rod and a strong lifting lug. The top rod is a split top rod, including a short top rod and a long top rod. One end of the short top rod is connected and fixed to the vertical support rod of the base, and the other end is connected to the 5 long top rods; the upper ends of the short top rod and the long top rod are both provided with strong lifting lugs.

[0012] The short push rod and the long push rod are both hexagonal rods, and the outer dimensions of the push rods gradually decrease from the long push rod to the short push rod.

[0013] The pile gripper assembly comprises a pile gripper, two pile gripper oil cylinders and a connecting shaft, wherein the pile gripper is connected to the push rod via the connecting shaft; the two pile gripper oil cylinders are arranged at both ends of the connecting shaft, and the two pile gripper oil cylinders are arranged in an eight-shaped shape, with one end of the two pile gripper oil cylinders arranged on the pile gripper and the other end arranged on the truss

[0014] On the top rod of the frame assembly, the two pile gripper cylinders are connected to the control system electrical signal.

[0015] A guide ring is arranged at the upper end of the pile gripper, and the guide ring is in a trumpet shape with a larger upper part and a smaller lower part. An inverted triangular opening is opened on the guide ring near the oil cylinders of the two pile grippers.

[0016] The pile gripper is a split sleeve, comprising two semicircular cards, one side of the two semicircular cards is connected by 5 rotating shafts, and the other side of the two semicircular cards are in contact connection.

[0017] The hull assembly includes a pontoon, a hull positioning rod and a living and operating room. The hull positioning rods are arranged at the four corners of the pontoon. The platform at the upper end of the pontoon is surrounded by guardrails. Two pile drivers and multiple winches are arranged on the platform at the upper end of the pontoon.

[0018] A method for using a pile-driving barge equipped with a side positioning tool comprises the following specific steps:

[0019] Step 1: The hull assembly is fixed in position by a hull positioning rod;

[0020] Step 2: Connect one end of the truss assembly to the base, install the pile gripper assembly on the other end, and use the pile driver to perform the piling operation;

[0021] Step 3: The pile driver drives the pipe pile into the pile gripper of the pile gripper assembly. After the pile driving is completed, the two pile gripper oil cylinders are controlled to retract to open the pile gripper. Then, the base oil cylinder is controlled to retract to drive the base to slide along the support, thereby driving the truss assembly to move and move the pile gripper on the truss assembly out of the pipe pile.

[0025] The pile gripper in the present invention is an integrated or split type, and one side of the two halves of the split type is connected by a rotating shaft. The outer sides of the two halves of the split type are connected with pile gripper cylinders. The pile gripper is opened by retracting the pile gripper cylinder, and the pile gripper can be closed by extending the pile gripper cylinder, so that the pipe pile can be driven into the pile gripper conveniently.

[0026] In the present invention, the base moves linearly in the support through the base oil cylinder, thereby driving the truss assembly connected to the base to move linearly. After the truss assembly moves, the pile gripper assembly arranged on the truss assembly moves along with the truss assembly. The pile gripper is opened and closed by the pile gripper oil cylinder. The present invention adopts the linkage of these two oil cylinders to move the pile gripper out of the lowered pipe pile for subsequent construction operations.

[0027] The top rod in the truss assembly of the present invention is a detachable top rod. The top rod includes a short top rod and a long top rod which are fixedly connected into one body through a connecting plate. The outer cross-sectional dimensions of the overall top rod gradually decrease from the short top rod to the long top rod, thereby reducing the weight of the top rod itself. Whether the short top rod in the top rod needs to be increased with a long top rod is determined according to the design requirements. After the long top rod is increased, one top rod can locate the positions of two pipe piles. The positioning speed becomes faster, which improves the construction efficiency.
