[0002] The pile frame of the pile driving ship is heavy, and the total weight after being equipped exceeds 1,300 tons. Due to the heavy weight of the super-large pile frame, it cannot be installed as a whole in the dock. Therefore, the pile frame of the pile driving ship generally needs to be hoisted and installed by a large floating crane after the ship is launched: after launching, the ship is moored at the dock, and the pile frame is made and hoisted as a whole by a floating crane. It is necessary to rent a floating crane, and the dispatch and construction costs of a large floating crane are high. The construction process requires multiple tugboats for escort and consignment, which is not economical and environmentally friendly. Summary of the invention

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0019] The pile frame 1 of the pile-driving ship is heavy, and the total weight after the equipment exceeds 1300 tons. A support beam 2 is installed at the stern of the pile-driving ship, and a living area is provided at the bow. The pile frame 1 is divided into two sections, such as Figure 5 As shown, the first section includes a pile frame head 11 and a pile frame body 12, and the second section is a pile frame foot 13. The pile frame foot 13 is assembled on a unified stand to ensure closing accuracy.

[0020] The side of the pile frame 1 close to the hull is set as the rear side, and the side away from the hull is set as the front side. A high connecting ear plate is installed on the front side of the pile frame foot 13, and a supporting section is installed on the rear side of the pile frame body 12 close to one end of the pile frame head 11. A hydraulic cylinder slide rail is laid between the front side of the pile frame body 12 and the rear side of the pile frame foot 13.

[0021] The support section includes a top fixing block, a middle vertical connecting block and a bottom gasket which are arranged in sequence from top to bottom, and the top fixing block is obliquely fixed on the inner wall of the rectangular groove, and the middle vertical connecting block and the bottom gasket are placed in the support platform.

[0022] In this embodiment, the weights of the pile frame head 11, the pile frame body 12 and the pile frame foot 13 are 200 tons, 500 tons and 350 tons respectively. The pile frame body 12 is also installed with 35 tons of outfitting parts and a 55-ton pulley block. The pile frame foot 13 is also installed with 25 tons of outfitting parts, 5 tons of piping, 5 tons of winch, 60 tons of pile gripper and 10 tons of plug-in pins.

[0023] A process for closing a pile frame 1 of a pile driving ship in mid-air comprises the following steps: S1. Barge the pile-driving barge into the dock.

[0024] S2. A high hinged ear plate is installed on the top of the supporting beam 2 of the pile-driving ship, and a transfer beam 6 is installed on the bottom of the supporting beam 2. The transfer beam 6 can bear 350 tons. A high support frame 4 is installed between the living area and the supporting beam 2 and close to the supporting beam 2 on the pile-driving ship. The high support frame 4 can bear 80 tons. A closing reference support frame 5 is installed between the living area and the high support frame 4. The closing reference support frame 5 can bear 80 tons. A second bracket 3 is installed on the top of the living area.

[0025] The second support 3 comprises a support platform, which is mounted on the top of the living area through a support frame and just accommodates the support section.

[0026] The support platform is U-shaped and includes a bottom plate and limiting plates on both sides.

[0027] A rectangular groove is provided on the bottom side of the pile frame body 12 to accommodate the support platform part extending therein, and the inclination of the rectangular groove is consistent with the inclination of the bottom side of the pile frame body 12 .

[0028] S3. Three first temporary platforms 14 are installed at one end of the pile frame foot 13 connected to the pile frame body 12, and two permanent platforms 15 are installed at one end of the pile frame body 12 connected to the pile frame head 11.

[0029] S4, such as Figure 1 As shown, the second section of the pile frame 1 is hoisted onto the high-hinged ear plate and the transfer beam 6 on the pile-driving ship by using a 500T gantry crane.

[0030] S5. Use two 500T gantry cranes to hoist the first section of the pile frame 1 (i.e., the pile frame body 12) onto the second bracket 3 and the closing reference support frame 5, and place the bottom connecting side of the pile frame body 12 in the three first temporary platforms 14 and align it with the pile frame foot 13 for closing. For the segmented closing, a clamping plate 7 should be made on the gantry and the side pipe, and a sample punching mark should be made to facilitate the closing use and inspection on board.

[0031] like Figure 3-4 As shown, there are four clamping plates 7 distributed around the side of the side pipe. The middle part of the inner side of the clamping plate 7 has an inwardly concave arc groove, and one end of the inner side of the clamping plate 7 has an inclined guide surface 8 to accommodate the insertion of the side pipe of the pile frame 1 installed later. A gap of 2 mm is left between the inwardly concave arc groove and the inclined guide surface 8 on the inner side of the clamping plate 7 and the side pipe, which can effectively reduce the centering error and improve the assembly accuracy.

[0032] When the overall weight of the first pile frame 1 is not less than 800 tons, it is necessary to first use a 500T gantry crane to install the pile frame body 12, and then align and close the pile frame head 11 with the pile frame body 12 for installation. When the overall weight of the first pile frame 1 is less than 800 tons, the pile frame head 11 is installed on the pile frame body 12 in advance to obtain the first pile frame 1, and then the obtained first pile frame 1 is hoisted together with the second pile frame 1 by using a gantry crane.

[0033] In this embodiment, the overall weight of the first section of the pile frame 1 (i.e., the pile frame head 11, the pile frame body 12, and the outfitting and pulley block on the pile frame body 12) is not less than 800 tons. It is necessary to first use a 500T gantry crane to install the pile frame body 12, and then align the pile frame head 11 and the pile frame body 12 for installation. Figure 2 shown.

[0034] S6. Debugging and fixing the first section pile frame 1 and the second section pile frame 1 to complete the installation of the pile frame 1 on the piling ship.

[0035] During the alignment and closing process of the first and second pile frames 1, the adjustment of the side pipe of the pile frame 1 installed later (i.e., the first pile frame 1) is mainly performed, and the adjustment of the side pipe of the pile frame 1 installed earlier (i.e., the second pile frame 1) is supplemented, and both the main and auxiliary methods are used.

[0036] When the side pipe of the pile frame 1 is butted, it is first slowly inserted into the guide plate, and then the gantry crane is adjusted and the precise positioning pin is driven in.
