Description

Technical Field

[0001] This utility model belongs to the field of combined sheet pile construction technology, specifically relating to a hydraulic automatic alignment device. Background Technology

[0002] Composite sheet piles possess advantages such as high bending strength, rational structural stress distribution, and good adaptability to loads and geological conditions, making them promising for widespread application in waterway engineering. Composite sheet piles consist of a combination of sheet piles and steel pipe piles, with long, heavy main piles alternating with short, lightweight auxiliary piles. During construction, the main piles are driven first, followed by the insertion of auxiliary piles between them.

[0003] In the prior art, Chinese utility model patent document with authorization announcement number CN217267395U discloses an assembly device for facilitating the combination of steel pipe piles and Larssen sheet piles. The first frame is used to be erected on two adjacent steel pipe piles, and the second frame is used to be fitted on the outer periphery of the lower side of the Larssen sheet pile. The telescopic end of the drive source is used to limit the second frame to the Larssen sheet pile. The length of the first frame is fixed, so it can only be used for the insertion and positioning of sheet piles between steel pipe piles with a certain spacing. However, in different projects, the number of sheet piles inserted between steel pipe piles varies, such as one or two. The above-mentioned prior art cannot be applied to the insertion and positioning of sheet piles with different spacings of steel pipe piles.

[0004] Therefore, it is necessary to design a hydraulic automatic alignment device that can be adjusted to cope with different numbers of sheet piles being driven and positioned between steel pipe piles, thereby expanding its applicability and solving the current technical problems.

[0022] like Figures 1 to 3As shown, a hydraulic automatic alignment device is disclosed, including two crossbeams 2, two sets of hydraulic centering and clamping mechanisms 1, and two sets of sheet pile guiding mechanisms 4. The two crossbeams 2 are parallel. A sliding sleeve 3 is fixedly installed on the top of the hydraulic centering and clamping mechanism 1 and is slidably fitted on the outside of the crossbeam 2. The sliding sleeve 3 is locked or released from the crossbeam 2. The sheet pile guiding mechanism 4 is detachably and fixedly installed between the middle of the two crossbeams 2. One set of sheet pile guiding mechanism 4 has a first support plate 41, on which a set of guiding components 43 are provided. The other set of sheet pile guiding mechanism 4 has a second support plate 42, on which two sets of guiding components 43 are provided. In this embodiment, the appropriate sheet pile guiding mechanism 4 is selected according to the actual situation of the project. Specifically, when there is one sheet pile between two adjacent steel pipe piles, the sheet pile guiding mechanism 4 with one set of guiding components 43 is selected; when there are two sheet piles between two adjacent steel pipe piles, the sheet pile guiding mechanism 4 with two sets of guiding components 43 is selected. The guide component 43 is matched with the sheet pile. Based on the distance between the centers of two adjacent steel pipe piles, the center distance of the two sets of hydraulic centering clamping mechanisms 1 is adjusted, and the two sets of hydraulic centering clamping mechanisms 1 are centered on the crossbeam 2. The sliding sleeve 3 is locked to the crossbeam 2, and then the required sheet pile guide mechanism 4 is assembled and fixed on the crossbeam 2 to complete the adjustment. By adjusting the distance between the two sets of hydraulic centering clamping mechanisms 1 and selecting and installing the corresponding sheet pile guide mechanism 4, the installation and positioning of one or two sheet piles between steel pipe piles can be handled, expanding the applicability. The guide component 43 in the sheet pile guide mechanism 4 positions the sheet pile during the installation process, improving the installation accuracy of the sheet pile and ensuring precise correspondence between the sheet piles and steel pipe piles, and between the sheet piles themselves. The hydraulic centering clamping mechanism 1 can be supported and fixed to the upper inner side of the steel pipe pile, providing stable support for the crossbeam 2 and the sheet pile guide mechanism 4 at its top, thus providing stable support for the installation and positioning of the sheet pile.

[0023] In some embodiments, the guide assembly 43 has a guide hole 431 provided on the first support plate 41 and the second support plate 42; the guide hole 431 is provided with an inner guide roller 433 and an outer guide roller 432 corresponding to the inner and outer sides of the middle section of the sheet pile, respectively, and a side guide roller 434 corresponding to the two sides inside the sheet pile.

[0024] The inner guide roller 433, outer guide roller 432, and side guide roller 434 are all rotatably arranged inside the guide hole 431; the inner guide roller 433 and outer guide roller 432 cooperate to limit and guide the steel sheet pile in the horizontal direction of the vertical beam, and the two side guide rollers 434 cooperate to limit and guide the steel sheet pile in the direction of extension of the beam 2.

[0025] In some embodiments, the first support plate 41 and the second support plate 42 are detachably fixed to the top of the crossbeam 2 by bolts; the crossbeam 2 is provided with internal threaded holes evenly arranged in the center, and the first support plate 41 and the second support plate 42 are provided with through holes corresponding to the internal threaded holes on both sides; the first support plate 41 and the second support plate 42 are assembled and fixed to the top of the crossbeam 2 by bolts.

[0026] In some embodiments, such as Figure 3 As shown, the hydraulic centering clamping mechanism 1 has a top plate 11, a lifting column 15 is arranged below the top plate 11, a hydraulic cylinder 14 is arranged at the top of the top plate 11 to drive the lifting column 15 to move up and down, at least three inner support rods 12 arranged in a circular array below the top plate 11 and parallel to the axis of the lifting column 15, two parallel connecting rods 13 are arranged between the inner support rods 12 and the lifting column 15, and a support rod 18 is hinged to the middle of the connecting rod near the upper end of the inner support rod 12, the upper end of the support rod 18 The top plate 11 is hinged to the bottom; the hydraulic cylinder 14 drives the lifting column 15 to move up and down, and the lifting column 15 drives one end of the connecting rod 13 to swing up and down, pushing the inner support rod 12 to move outward or inward synchronously. When the inner support rod 12 moves outward synchronously, it can be fixed against the upper end of the steel pipe pile, while ensuring that the center of the top plate 11 corresponds to the axis of the steel pipe pile. When the inner support rod 12 retracts inward synchronously, it can release the upper end of the steel pipe pile, so that the hydraulic centering clamping mechanism 1 can be taken out from the upper end of the steel pipe pile.

[0027] In some embodiments, the bottom end of the inner support rod 12 is provided with a bend 17 that bends toward the lifting column 15. The bend 17 and the inner support rod 12 are an integral structure. The bend 17 makes the diameter of the virtual circle formed by the lower end of the inner support rod 12 smaller, so as to facilitate the insertion of the hydraulic centering clamping mechanism 1 into the upper end of the steel pipe pile.

[0028] In some embodiments, two connecting plates 16 are symmetrically arranged on the top plate 11, and the sliding sleeve 3 is fixedly disposed on the top of the connecting plate 16; specifically, the sliding sleeve 3 is welded and fixed to the top of the connecting plate 16.

[0029] In some embodiments, the side of the sliding sleeve 3 is provided with bolts for locking or releasing it between the sliding sleeve 3 and the crossbeam 2; the side of the bolt sliding sleeve 3 is threaded, and by tightening or loosening the bolts, the end of the bolts abuts against or moves away from the crossbeam 2, thereby achieving locking or releasing between the sliding sleeve 3 and the crossbeam 2.
