Description

Technical Field

[0001] This utility model relates to the field of piling, specifically to a piling machine. Background Technology

[0002] A previous patent application entitled "A Piling Device for Improving Piling Efficiency in Deep Water Areas" (application number: 202323578518.7) discloses a waterborne piling device that achieves precise adjustment of the piling position through the cooperation of an anchor cable system and a cross-traverse system. While this device improves piling efficiency and accuracy compared to traditional piling machines, after the piling machine reaches the designated piling position, the support legs forming the cross-traverse system need to be lowered via hydraulic cylinders to fix the position of the auxiliary base. Then, the position of the main base is adjusted to achieve piling at different locations. Fixing the auxiliary base position by adjusting the lowering of the support legs with hydraulic cylinders is time-consuming and inefficient. Furthermore, for areas with greater depth, the length of the support legs needs to be very large or completely insufficient. Additionally, it cannot adapt to the ebb and flow of tides during offshore construction. Therefore, it is necessary to address this problem. Summary of the Invention

[0003] The purpose of this invention is to provide a pile driver that can solve the above-mentioned problems.

[0004] The technical solution adopted in this utility model is as follows.

[0005] A pile driver, characterized in that: it includes a main base and an auxiliary base, the auxiliary base being respectively arranged on both sides of the main base; the main base is provided with a pile driving mechanism for driving piles; the auxiliary base is respectively provided with positioning rods that can sink under their own weight; the positioning rods sink to the underwater ground below the auxiliary base to limit the position of the auxiliary base; the positioning rods are movably arranged; and the positioning rods are connected to the auxiliary base by connecting ropes.

[0006] The specific operation includes a rope adjustment component, which winds up or releases the connecting rope.

[0007] The auxiliary base is equipped with multiple positioning rods.

[0008] The auxiliary base is equipped with two positioning rods, which are located at both ends of the auxiliary base.

[0009] The auxiliary base has vertically arranged support rods at both ends, and a pulley assembly is provided at the upper end of the support rod. The rope adjustment assembly includes a winch located next to the support rod. One end of the connecting rope passes around the pulley and is wound on the winch, and the other end of the connecting rope is connected to one end of the positioning rod column.

[0010] The other end of the positioning rod is set in a conical shape.

[0011] The auxiliary base is provided with a gap for the positioning rod to be lowered and raised, and the gap is located near the support rod.

[0012] The weight of the positioning rod is 2 to 3 tons.

[0013] The positioning rod has a steel outer layer and a concrete inner layer.

[0014] A hydraulic walking mechanism is installed on the auxiliary base.

[0015] The technical solution provided by this utility model uses a positioning rod to fix the position of the auxiliary machine base. Compared with the method of using a hydraulic cylinder to drive the support leg, the operation is simpler and faster, and it can solve the problems of large water depth and changes in water level, thereby improving piling efficiency and adaptability.

[0016] Figure 1 This is a top-view schematic diagram of a partial structure of a pile driver.

[0017] Figure 2 This is a side view of the positioning rod, support rod, and winch.

[0018] Drawing number explanation: 11-Main machine base, 12-Sub-machine base, 21-Positioning rod, 22-Support rod, 23-Winch, 24-Connecting rope, 25-Pulley assembly. Detailed Implementation

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] As used herein, the terms “parallel,” “perpendicular,” etc., are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0021] The solution adopted in this utility model is as follows: Figure 1 As shown, a pile driver is characterized by comprising a main base 11 and a secondary base 12, with the secondary base 12 respectively disposed on both sides of the main base 11. The main base 11 is provided with a pile driving mechanism for driving piles, and the secondary base 12 is provided with positioning rods 21 that can sink under their own weight. The positioning rods 21 sink to the underwater ground below the secondary base 12 to define the position of the secondary base 12. The positioning rods 21 are movably disposed and are connected to the secondary base 12 by connecting ropes 24.

[0022] This utility model is a further improvement on the existing pile driver. Therefore, for structures and mechanisms not described in detail, they can all be implemented according to existing technical solutions. For example, the connection structure between the main base 11 and the auxiliary base 12 can be operated according to the scheme described in the earlier application "A Split-Type Structure Pile Driver Base" (application number: 202120725011.1). The positioning rod 21 provided in this utility model is different from the existing anchor cable system. The anchor cable system throws the anchor to a position far away from the pile driver, so that the pile driving vessel can move or stop in a preset direction by raising and lowering the anchor cable. However, the positioning rod 21 provided in this utility model fixes the position of the auxiliary base 12 after the pile driver has moved to the designated position, so that the main base 11 can be adjusted relative to the auxiliary base 12 to achieve pile driving at different positions. Specifically, the auxiliary base 12 is also equipped with an anchor cable mechanism, which includes an anchor and an anchor cable connecting the anchor and the auxiliary base 12. The anchor is deployed to the periphery (outer side) of the pile driver. More specifically, the anchor cable mechanism can be implemented according to the technical solution described in the prior application "A Pile Driving Equipment for Improving Pile Driving Efficiency in Deep Water Areas" (application number: 202323578518.7). The auxiliary base 12 is specifically fixed in position by the positioning rod 21. Compared with the method of fixing by using hydraulic cylinders to drive the support legs, the operation is faster and can solve the problems of large water depth and changes in water level, thereby improving pile driving efficiency and adaptability.

[0023] Further as Figure 2 As shown, it also includes a rope adjusting assembly, which winds up or releases the connecting rope 24. Multiple positioning rods 21 are provided on the auxiliary base 12; preferably, two positioning rods 21 are provided on the auxiliary base 12, located at both ends of the auxiliary base 12. More specifically, vertically arranged support rods 22 are provided at both ends of the auxiliary base 12. A pulley assembly 25 is provided at the upper end of the support rod 22. The rope adjusting assembly includes a winch 23 located beside the support rod 22. One end of the connecting rope 24 passes over the pulley and is wound onto the winch 23. The other end of the connecting rope 24 is connected to one end of the positioning rod 21. The connecting rope 24 can be a steel wire rope. The other end of the positioning rod 21 is tapered. The auxiliary base 12 has a gap for the positioning rod 21 to fall and rise, and the gap is located near the support rod 22. The weight of the positioning rod 21 is 2-3 tons. The positioning rod 21 has a steel outer layer and a concrete inner layer. A hydraulic walking mechanism is installed on the auxiliary base 12.

[0024] The above-described scheme offers low implementation costs and simplifies the lifting operation of the positioning rod 21, making it quick and easy. Its conical structure allows the positioning rod 21 to sink and be firmly fixed to the underwater surface. Simultaneously, a positioning rod 21 is installed at each end of the auxiliary base 12, each equipped with a winch 23 and a support rod 22, ensuring reliable fixation of the auxiliary base 12. The hydraulic walking mechanism of this invention is primarily designed to facilitate the movement of the pile driver on land. The positioning rod 21 can be detachable, allowing it to be removed when not in use. Before the pile driver moves to the designated position, the positioning rod 21 is suspended on the auxiliary base 12. After moving to the designated position, the winch 23 releases the connecting rope 24, and the positioning rod 21 sinks vertically to its position on the underwater surface under its own weight, thus reliably fixing the auxiliary base 12.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
