Description

Technical Field

[0001] This utility model relates to the field of riverbank construction technology, and in particular to a riverbank piling positioning device and a construction vessel equipped with the riverbank piling positioning device. Background Technology

[0002] In practice, to reinforce riverbanks, a row of piles is typically driven vertically along the riverbank using a construction vessel. However, existing pile-driving vessels face challenges in accurately determining the vertical alignment of the piles before driving, resulting in low efficiency. Furthermore, they struggle with precisely controlling the spacing between adjacent piles. Therefore, developing a novel pile-driving positioning device to overcome these problems is a direction that requires further research by those skilled in the art. Utility Model Content

[0003] The primary objective of this invention is to provide a riverbank piling positioning device for quickly achieving vertical alignment of the piles before piling during construction, thereby reducing operational difficulty and improving work efficiency and construction quality.

[0004] The second objective of this utility model is to provide a construction vessel equipped with the aforementioned riverbank piling and positioning device.

[0005] This utility model discloses a riverbank piling and positioning device, which includes:

[0006] The first positioning post has a column body that extends vertically and includes a first pile positioning surface that is a vertical plane.

[0007] A fixed base is fixedly connected to the lower end face of the first positioning column as a whole;

[0008] A positioning cylinder is integrally connected to the fixed base. One end of the positioning cylinder is provided with an output shaft that extends horizontally and is used for reciprocating between the extension position and the retraction position. The positioning cylinder is configured such that when the output shaft moves to the extension position, the end of the output shaft is located in front of one side of the positioning surface of the first pile body.

[0009] This technical solution involves installing a riverbank piling positioning device on one side of the construction vessel, with a portion of the first positioning column exposed above the water surface and the fixing base submerged underwater. During piling operations, the pile is lifted by a crane, and workers support the pile with both hands, controlling one side of the column to slowly move downwards along the first pile positioning surface. Simultaneously, a positioning cylinder is activated to move the output shaft to its extended position, so that the end of the output shaft rests in a groove on one side of the pile, thus positioning the underwater portion of the pile and preventing it from shifting underwater. The piling operation is then carried out.

[0010] Preferably, it further includes: a second positioning post, the second positioning post being located on the side of the first positioning post away from the positioning cylinder, the second positioning post having the same shape as the first positioning post, the second positioning post including a second pile positioning surface that is vertically planar, the second pile positioning surface and the first pile positioning surface being parallel to each other in the same vertical plane; a gap is provided between the second positioning post and the first positioning post; the fixed base is fixedly connected to the lower end face of the first positioning post as a whole.

[0011] This technical solution involves the following steps: After one pile is driven in, the construction vessel moves one distance until the second positioning column moves to the second pile's positioning surface and aligns with the first pile. Simultaneously, a crane lifts the second pile, and workers support it with both hands, slowly moving it downwards along one side of the column while keeping it against the first pile's positioning surface. At the same time, the output shaft of the positioning cylinder is positioned in a groove on one side of the second pile, thus positioning the second pile underwater. Since the distance between the second and first positioning columns is constant, repeating this process ensures that the distance between any two adjacent driven piles remains essentially consistent.

[0012] Preferably, a first slider is connected to the column body of the first positioning post, and the first slider is located at the top of the side of the column body of the first positioning post facing away from the positioning surface of the first pile body; a second slider is connected to the column body of the second positioning post, and the second slider is located at the top of the side of the column body of the second positioning post facing away from the positioning surface of the second pile body.

[0013] By adopting this technical solution: setting a straight chute on the construction vessel, and sliding the first slider and the second slider on the straight chute respectively, the installation and relative movement of the riverbank piling positioning device on the construction vessel can be realized.

[0014] Preferably, both the first positioning post and the second positioning post are rectangular columns made of metal, and the end of the output shaft is provided with a circular guide wheel.

[0015] By adopting this technical solution, as the worker supports the pile with both hands and controls the pile to move slowly downward along one side of the pile body against the first pile positioning surface, the circular guide wheel rotates in the groove on one side of the pile body, thereby avoiding friction damage to the end of the output shaft during this process and making the downward movement of the pile body smoother.

[0016] This utility model also discloses a construction vessel, which includes the riverbank piling positioning device described in any of the above-mentioned embodiments.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] First, this invention can quickly achieve vertical correction of the pile column before piling, thereby reducing the difficulty of operation and improving work efficiency and construction quality.

[0019] Secondly, this invention can effectively ensure that the spacing between two adjacent piles remains basically consistent during continuous pile driving operations.

[0020] Thirdly, this utility model can slide and move on the construction vessel, making it convenient to operate and use on the construction vessel.

[0021] Finally, this invention has a simple structure and is easy to prepare and implement. Attached Figure Description

[0026] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0027] Example 1, please refer to Figure 1-2 :

[0028] A construction vessel for performing riverbank piling construction includes: a hull 100, on which conventional piling construction equipment such as a crane 110 and a hydraulic piling machine 120 are installed. This part of the structure is existing technology in the field and will not be described in detail in this article.

[0029] The hull 100 is also equipped with a slide rail 130 and a riverbank piling positioning device 200 on one side. The riverbank piling positioning device 200 further includes: a first positioning post 210, a fixed base 220, a positioning cylinder 230, and a second positioning post 240.

[0030] The first positioning post 210 extends vertically and includes a first pile positioning surface 211 that is vertically planar. The fixed base 220 is fixedly connected to the lower end face of the first positioning post 210. The positioning cylinder 230 is connected to the fixed base 220. One end of the positioning cylinder 230 is provided with an output shaft that extends horizontally and is used for reciprocating between the extension position and the retraction position. The positioning cylinder 230 is configured such that when the output shaft moves to the extension position, the end of the output shaft is located in front of the first pile positioning surface 211 on one side. The second positioning post 240 is located on the side of the first positioning post 210 away from the positioning cylinder 230. The second positioning post 240 has the same shape as the first positioning post 210. The second positioning post 240 includes a second pile positioning surface 241 that is vertically planar. The second pile positioning surface 241 and the first pile positioning surface 211 are parallel to each other in the same vertical plane. There is a gap between the second positioning post 240 and the first positioning post 210. The fixed base 220 is fixedly connected to the lower end face of the first positioning post 210 as a whole.

[0031] A first slider 212 is connected to the column of the first positioning post 210, and the first slider 212 is located on the top of the side of the column of the first positioning post 210 facing away from the positioning surface 211 of the first pile body; a second slider 242 is connected to the column of the second positioning post 240, and the second slider 242 is located on the top of the side of the column of the second positioning post 240 facing away from the positioning surface 241 of the second pile body. The first slider 212 and the second slider 242 are slidably mounted on the slide rail 130. In this example, both the first positioning post and the second positioning post are rectangular columns made of metal. A circular guide wheel 231 is provided at the end of the output shaft.

[0032] In practice, its working process is as follows:

[0033] The riverbank piling positioning device 200 is installed on one side of the hull 100 of the construction vessel, with a portion of the first positioning column 210 exposed above the water surface and the fixing base 220 submerged underwater. During piling operations, the riverbank piling positioning device 200 is moved along the slide rail 130 to a position close to the hydraulic piling machine 120. Then, the first pile is lifted by a crane and moved to a position close to the first positioning column 210. Workers support the pile with both hands, controlling one side of the column to slowly move downwards into the river water, keeping it against the first pile positioning surface 211. Simultaneously, the positioning cylinder 230 is activated, moving the output shaft to the extended position, so that the circular guide wheel 231 at the end of the output shaft rests against a groove on one side of the pile, thus positioning the underwater portion of the pile and preventing it from shifting underwater. The piling operation is then carried out on the pile. After the first pile is driven, the construction vessel is moved one distance until the second positioning column 240 moves to the second pile positioning surface 241 and is in contact with the first pile. Simultaneously, the second pile is lifted by a crane and moved closer to the first positioning column 210. Workers support the pile with both hands, controlling one side of its body to slowly move downwards into the water while keeping it against the first pile positioning surface 211. At the same time, the output shaft of the positioning cylinder 230 is positioned against a groove on one side of the second pile, thus positioning the second pile underwater. Since the distance between the second positioning column 240 and the first positioning column 210 is constant, repeating the above process ensures that the distance between all adjacent driven piles remains essentially consistent.

Even if various changes are made to this utility model, if these changes fall within the scope of the claims of this utility model and their equivalents, they shall still fall within the protection scope of this utility model.
