Technical Field

[0001] The invention relates to the technical field of pile frame construction of a piling ship, and in particular to a segmented manufacturing method of a longkou track of a pile frame of a piling ship. Background Art

[0002] A pile-driving ship is a vessel used for pile-driving operations on water. The hull is a steel box structure, and a pile-driving frame is installed at the end of the deck, which can be tilted forward and backward to meet the needs of driving inclined piles. A pile-driving ship is a non-self-propelled ship, which is towed into place by a pusher (tug) wheel. Pile-driving ships are widely used in the construction of bridges, docks, and water conservancy projects.

[0003] The long mouth of the pile frame of the pile driving ship is the running track structure of the pile hammer and the lifting platform, and the structural accuracy is required to be high. In order to ensure the accuracy of the long mouth of the pile frame, the general process is to install the long mouth track last after the pile frame structure is built. When the long mouth track is installed last, the installation space of the components is small or high-altitude operation is required, which makes the installation difficult, the operation is dangerous, and the workload is large. Although the accuracy of the long mouth track can be guaranteed, the efficiency is low, which prolongs the project construction period. Summary of the invention

Position and install the panel of the dragon mouth segment. The dragon mouth panel is fixed with a U-shaped pallet. During installation, first measure the overall flatness of the dragon mouth joint, then put the dragon mouth panel in place, and the U-shaped pallet is set corresponding to the dragon mouth cross rib plate; S4. Install the lifting platform rail. Leave 1 meter of the lifting platform rail at the closing mouth for welding, which is used for closing and adjusting between sections. S5. Install the cross beam and then the inclined beam. The inclined beam is connected with the front limb tube and the front support foot base structure, and then welded after the intersection and positioning.

[0013] The main pile frame 10, the auxiliary pile frame 20 and the structure of the dragon mouth 1 of the pile driving ship pile frame are as follows Figure 1 As shown, this specific implementation adopts the following technical solution: when the pile frame is constructed, it is constructed based on the Longkou track, and the Longkou track installation process is moved forward, including the following steps: S1. Divide the Longkou 1 into several sections, and construct the Longkou sections 11 and the lifting platform tracks 2 respectively. The length of each lifting platform track 2 is 6-8 meters. When cutting the Longkou panel 3, add a 20mm margin in the width direction, and add a 20mm margin on the outside of the Longkou track plate. Before installing the Longkou track plate, straighten and mill the edges.

[0014] S2. When assembling the segmented columns, install the Longkou segment 11 simultaneously. Figure 2 As shown, at this time, the panel 3 of the dragon mouth segment 11 and the lifting platform track 2 are not installed. Before the dragon mouth 1 is installed, the center line of the dragon mouth closure is measured and determined, and a benchmark is made; Figure 3 As shown, the Longkou segment 11 is installed based on the Longkou structure center line a. The tolerance of the rib size of the Longkou segment 11 does not exceed ±3mm, and the structural position deviation at the interface between the column and the beam does not exceed ±5mm, to prevent sudden shifting of the joint position and out-of-tolerance welding angles.

[0015] When the Longkou section 11 is welded with the main pile frame 10 and the auxiliary pile frame 20, the rear panel of the Longkou section 11 is butt-welded with the cross beam panel of the main pile frame 10 and the auxiliary pile frame 20; the web of the Longkou section 11 is double-sidedly welded with the cross beam panel of the main pile frame 10 and the auxiliary pile frame 20, and the weld height is 12 mm; the rear panel of the Longkou section 11 is butt-welded with the diagonal I-beam panel of the main pile frame 10; the rear panel of the Longkou section 11 is double-sidedly welded with the web of the diagonal I-beam of the main pile frame 10, and the weld height is 12 mm; the web of the Longkou section 11 is single-sidedly welded with the vertical beam panel of the main pile frame 10; the partition of the Longkou section 11 is double-sidedly welded with the cross beam panel of the main pile frame 10, and the weld height is 8 mm.

[0016] S3, Panel 3 of Longkou segment 11 is positioned and installed, such as Figure 4 As shown, the dragon mouth panel 3 is fixed with a U-shaped pallet 4. During installation, the overall flatness of the dragon mouth joint is measured first, and then the dragon mouth panel 3 is placed in place. The U-shaped pallet 4 is set corresponding to the dragon mouth cross rib plate, and the U-shaped pallet 4 is cut with materials above 12 mm.

[0017] S4. Installation of the lifting platform track. Leave a 1-meter length of the lifting platform track at the closing mouth for welding, which is used for closing and adjusting between sections. When closing the sections, the straightness of the lifting platform track is controlled with a precision of 6mm / 6000mm, with a maximum deviation of no more than 20mm. The overall accuracy requirement is to ensure the overall accuracy of the pile frame after production is completed and to ensure the overall posture of the pile frame dragon mouth.

[0018] S5, such as Figure 5 As shown, the cross beam 5 is installed and then the oblique beam 6 is installed. The oblique beam 6 is connected with the front limb tube and the front support foot base structure. The positioning accuracy of this position is high, and welding is performed after the intersection and positioning.

[0019] By dividing the dragon mouth into several sections, the dragon mouth structure is constructed in sections to ensure the accuracy of the dragon mouth; in order to ensure that the pile frame and the ship are built at the same time, the pile frame construction process is optimized, and the pile frame of the pile-driving ship is constructed based on the dragon mouth track.
