Description

Technical Field

[0001] The invention relates to the field of piling, and in particular to a pile driver. Background Art

[0002] In the patent application entitled "A piling device for improving the efficiency of piling in deep water areas" (application number: 202323578518.7), a water piling device is provided. Through the cooperation of the anchor cable system and the cross-walking system, the precise adjustment of the piling position is achieved. Although this device can improve the efficiency and accuracy of piling compared to traditional pile drivers, after the pile driver runs to the corresponding piling position, it is necessary to drive the support legs that make up the cross-walking to fall through the oil cylinder, so as to fix the position of the auxiliary machine base of the pile driver, and then adjust the position of the main machine base to achieve piling at different positions. The position of the auxiliary machine base is fixed by adjusting the support legs to descend through the oil cylinder, which takes a long time to adjust and is inefficient. In addition, for areas with greater depth, the length of the support legs needs to be set very large or cannot meet the requirements at all. In addition, when constructing on the sea surface, it is impossible to adapt to the situation of low tide and high tide. Therefore, it is necessary to solve this problem. Summary of the invention

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

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

[0021] The scheme adopted by the present invention is as follows Figure 1 As shown, a pile driver is characterized in that it includes a main machine base 11 and an auxiliary machine base 12, the auxiliary machine base 12 is respectively arranged on both sides of the main machine base 11, the main machine base 11 is provided with a piling mechanism for driving a pile body, and the auxiliary machine base 12 is respectively provided with a positioning rod column 21 that can sink by its own weight, the positioning rod column 21 sinks to the underwater ground below the auxiliary machine base 12 to limit the position of the auxiliary machine base 12, the positioning rod column 21 is movably arranged, and the positioning rod column 21 is connected to the auxiliary machine base 12 through a connecting rope 24.

[0022] The present invention is a further improvement on the existing pile driver, so for the structures and mechanisms that are not described in detail, they can be implemented according to the 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 recorded in the previously applied "A split-structure pile driving equipment base" (application number: 202120725011.1). The positioning rod column 21 provided in the present invention 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 ship can move or stop in a preset direction by retracting and releasing the anchor cable. The positioning rod column 21 provided in the present invention is to fix the position of the auxiliary base 12 after the pile driver runs to the specified position, so that the main base 11 can be adjusted relative to the auxiliary base 12, so as to achieve piling at different locations. Specifically, an anchor cable mechanism is also provided on the auxiliary base 12, and the anchor cable mechanism includes an anchor and an anchor cable that realizes the connection between the anchor and the auxiliary base 12, and the anchor is thrown to the periphery (outside) of the pile driver. More specifically, the anchor mechanism can be implemented according to the technical solution described in the prior application "A piling device for improving the efficiency of piling in deep water" (application number: 202323578518.7). The position of the auxiliary machine base 12 is specifically fixed by the positioning rod column 21. Compared with the fixation method of using a hydraulic cylinder to drive the support legs, the operation is faster and can solve the situation of large water depth and changes in water surface height, thereby improving the piling efficiency and adaptability.

[0023] Further Figure 2 As shown: it also includes a rope adjustment component, which reels or releases the connecting rope 24. A plurality of positioning rods 21 are provided on the auxiliary machine base 12. Preferably, two positioning rods 21 are provided on the auxiliary machine base 12, and the positioning rods 21 are respectively provided at both ends of the auxiliary machine base 12. More specifically, vertically arranged support rods 22 are respectively provided at both ends of the auxiliary machine base 12, and a pulley assembly 25 is provided at the upper end of the support rod 22. The rope adjustment component includes a winch 23 located beside the support rod 22, one end of the connecting rope 24 is wound around the pulley and then wound on the winch 23, and the other end of the connecting rope 24 is connected to one end of the positioning rod 21. The connecting rope 24 can be specifically a steel wire rope. The other end of the positioning rod 21 is arranged in a cone shape. A vacant portion for the positioning rod 21 to fall and rise is provided on the auxiliary machine base 12, and the vacant portion is arranged adjacent to the support rod 22. The weight of the positioning rod 21 is 2 to 3 tons. The positioning rod column 21 has a steel material layer on the outside and a concrete material layer on the inside. A hydraulic travel mechanism is arranged on the auxiliary machine base 12 .

[0024] The above scheme is adopted for specific implementation, with low implementation cost, and the lifting operation of the positioning rod column 21 is simple, convenient and fast. The positioning rod column 21 is set in a pointed cone structure, so that the positioning rod column 21 can be well sunk and fixed on the underwater ground. At the same time, a positioning rod column 21 is respectively set at both ends of the auxiliary machine base 12, and the positioning rod column 21 is respectively equipped with a group of winches 23 and support rods 22, which can realize the reliable fixation of the position of the auxiliary machine base 12. The setting of the hydraulic walking mechanism of the present invention is mainly to facilitate the walking of the pile driver on land. The positioning rod column 21 can be set as a detachable structure, which can be disassembled when it is not needed. Before the pile driver moves to the specified position, the positioning rod column 21 is suspended on the auxiliary machine base 12. After moving to the specified position, the winch 23 releases the connecting rope 24, and the positioning rod column 21 sinks vertically on the underwater ground by its own weight, thereby realizing the reliable fixation of the auxiliary machine base 12.

[0025] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
