Description

Technical Field

[0001] The utility model relates to equipment for an offshore engineering platform, and more specifically, to an all-rotating offshore ship-mounted pile driver and crane. Background Art

[0002] Offshore pile foundation engineering is the platform for the construction of various types of offshore engineering facilities. Therefore, whether it is the high-pile platform of an offshore city in shallow overlying water coral reef geological conditions, the construction of an offshore wind farm, or the construction of a cross-sea bridge and a port terminal, offshore pile driving operations are required. Offshore pile driving operations generally use a large hoisting ship or a large floating crane platform as a carrier, and utilize the crane mounted thereon to construct offshore wind power high-pile cap piles, jacket piles, and large bridge pile foundations by means of hydraulic hammer hoisting.

[0003] The existing luffing pile driver installed on a pile driving ship can only perform construction operations at the stern of the ship. The pile frame of the luffing pile driving ship can rotate slightly in a pitching manner around the front fulcrum, which can meet the requirements of driving vertical piles and inclined piles. However, during its operation, the ship needs to be frequently relocated for positioning, resulting in extremely low work efficiency. Summary of the Utility Model

[0040] In order to better understand the above technical solution of the utility model, the technical solution of the utility model will be further described below with reference to the drawings and embodiments.

[0041] Combined with Figure 1 and Figure 2 shown, a marine full-slewing crane pile driver provided by the utility model includes a full-slewing lifting device 10 and a pile driving device 20.

[0042] The full-slewing lifting device 10 includes a base 11, a slewing bearing 12, a slewing chassis 13, a guy derrick 14 and a boom 15.

[0043] The base 11 is arranged as a cylindrical body and is connected to the slewing chassis 13 through the slewing bearing 12 to drive the slewing chassis 13 (the whole machine) to make a rotational movement.

[0044] The A-frame 14 is welded to the slewing chassis 13 through a structure.

[0045] The lower end of the boom 15 is movably connected to the A-frame 14 through a hinge shaft, and the A-frame 14 is further wound around the boom 15 through a steel wire rope 17 to drive the boom 15 to perform luffing motion.

[0046] A machine room and an electrical room 131 are arranged on the slewing chassis 13.

[0047] The piling device 20 includes a pile frame 21, a fork frame 22 and a winding mechanism.

[0048] A slide rail is arranged on the pile frame 21, and a sliding shoe 23 is arranged on the slide rail. The pile frame 21 is connected to the upper end of the boom 15 through the sliding shoe 23.

[0049] The fork frame 22 is arranged in a multi-section push-pull telescopic type. One end of the fork frame 22 is movably connected to the pile frame 21 through a pin shaft, and the other end is movably connected to the A-frame 14 through a pin shaft.

[0050] The platform on the pile frame 21 is connected to the corresponding winch in the machine room through a winding mechanism.

[0051] A main hoist winch 132, a luffing winch 133, a hammer lifting winch 134, a main piling hook winch 135, a secondary piling hook winch 136 and a rigging / hammer lifting winch 137 are arranged in the machine room.

[0052] Among them, the main hoist winch 132, the luffing winch 133, the main piling hook winch 135 and the secondary piling hook winch 136 can adopt motor frequency conversion drive; the hammer lifting winch 134 and the rigging / hammer lifting winch 137 adopt an internal expanding clutch, and the pressure of the clutch oil cylinder can be dynamically controlled to adjust the falling speed of the hydraulic hammer 212, avoiding the impact force generated during pile slipping and reducing the risk of damage to the hydraulic hammer 212.

[0053] The rigging / hammer lifting winch 137 is usually in a standby state. Only when the hydraulic hammer 212 driven by the hammer lifting winch 134 is damaged, the hydraulic hammer 212 is replaced with a spare diesel hammer. The diesel hammer is connected to the rigging / hammer lifting winch 137 through a steel wire rope, and the rigging / hammer lifting winch 137 drives the diesel hammer to operate. The rigging / hammer lifting winch 137 can be used as a backup piling solution and can also be used for the later improvement of the crane, that is, as a rigging hook of the crane.

[0054] The electrical room 131 is offset to one side of the machine room. A transformer, a frequency conversion cabinet and monitoring equipment are arranged in the electrical room 131.

[0055] A hydraulic pump station 138 is arranged on the slewing chassis 13 on the other side of the machine room to support the winch brakes and clutches in the machine room.

[0056] An outdoor pump station 139 for placing a hydraulic control pump station and / or a diesel hammer control unit is also arranged outside the electrical room 131.

[0057] As shown in combination Figures 3 to 6 The platform on the pile frame 21 includes a hammer hanging platform 211 and a pile hanging platform. It is also possible to arrange only one hammer hanging platform 211 or pile hanging platform, or combine the hammer hanging platform 211 and the pile hanging platform into one platform.

[0058] A hydraulic hammer 212 and a pulley block 213 are configured on the hammer hanging platform 211.

[0059] A steel wire rope 214 is connected to the hydraulic hammer 212. The steel wire rope 214 is wound around the pulley block 213 and connected to the corresponding hammer hanging winch 134 and hammer lifting winch 137. Through the operation of the hammer hanging winch 134 and the hammer lifting winch 137, it is wound around the pulley block 213 through the steel wire rope 214, and finally the hydraulic hammer 212 is driven to move up and down.

[0060] A water cooling system is arranged on the hydraulic hammer 212. Compared with the traditional air cooling, the water cooling system has higher cooling efficiency and smaller volume, and is applicable to high-intensity pile driving operation conditions. Cooling water is taken from the ship's special fresh water tank, and the cooling water is transported to the hydraulic hammer pump station through the central water slip ring of the central collector. The high-temperature water in the pump station passes through the annular water tank of the cylinder body and circulates into the ship's special fresh water tank.

[0061] A main hoisting hook 216 is arranged at the middle position of the pile frame 21 through 215.

[0062] The pile frame 21 can realize the adjustment of the position, height and angle required by the pile frame 21 with the luffing movement of the boom 15, the hoisting movement of the main hoisting hook 216 and the telescopic movement of the fork frame 22.

[0063] Two main pile driving hooks and two auxiliary pile driving hooks can also be arranged on the pile hanging platform, and they are symmetrically arranged along the center of the pile frame 21, so that the pile can be lifted regardless of which side of the transport ship 2 berths. Using two of the main hooks and one auxiliary hook, the work of lifting the pile, turning the pile, twisting the pile and sleeving the pile can be quickly realized.

[0064] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as it is within the scope of the essential spirit of the present invention, the changes and modifications of the above embodiments will fall within the scope of the claims of the present invention.
