Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe pile lifting construction, in particular to a steel pipe pile lifting device. Background Art

[0002] At present, during the construction of high-pile docks, steel pipe piles need to be constructed. That is, the two ends of the steel pipe placed horizontally on the ground are connected to the steel wire rope of the hoist respectively, and then the hoist is lifted by a crane to make the steel pipe pile vertical. After that, it is lifted to the construction site and placed vertically on the piling equipment (pile driver or pile driving ship), and the piling equipment clamps it from the outside and impacts it downward.

[0003] The patent (publication number: CN113336073A) discloses a method for lifting offshore steel pipe piles. The method includes the following steps: during the actual lifting process, the offshore steel pipe pile lifting assembly can be first installed on the steel pipe so that the side wall of the steel pipe is inserted into the receiving groove; then the auxiliary lifting vessel is controlled to apply a lifting force to the offshore steel pipe pile lifting assembly through the second lifting part, so that the offshore steel pipe pile lifting assembly and the steel pipe are kept stable; then the main lifting vessel is controlled to lift the main lifting lug in the middle of the steel pipe through the first lifting part, and at the same time, the auxiliary lifting vessel is controlled to make the offshore steel pipe pile lifting assembly and the main lifting lug rise synchronously; then, after the steel pipe is lifted to the specified position, the main lifting vessel is controlled to drive the main lifting vessel to lift the steel pipe pile. The lifting lug rises, so that the offshore steel pipe pile lifting assembly is separated from the steel pipe; finally, after the main lifting lug rises until the steel pipe pile is vertical, the first lifting part is removed from the main lifting lug; during the lifting process, the offshore steel pipe pile lifting assembly can apply auxiliary lifting force to the steel pipe through the accommodating groove, so that the steel pipe is stably moved during the lifting process. After the steel pipe is lifted and placed in the specified position, the main crane ship is controlled to drive the main lifting lug to rise. At this time, the steel pipe is tilted, and the offshore steel pipe pile lifting assembly slides out from the lower end of the steel pipe pile under the action of gravity, so that the offshore steel pipe pile lifting assembly is separated from the steel pipe. Compared with the existing lifting method, there is no need to manually cut and remove the lifting lugs and lifting ropes separately, which effectively increases the lifting efficiency.

[0004] In the above process, since the piling equipment clamps the steel pipe piles, the lifting ears often interfere with the outer clamp equipment. Moreover, during transportation, the lifting ears on the outer side of the steel pipe sometimes collide with adjacent steel pipe piles or lifting ears, causing the lifting ears to deform, reducing the bearing capacity, and thus increasing the lifting risk. Utility Model Content

[0005] The purpose of the utility model is to overcome the problems existing in the background technology that the lifting lugs often interfere with the outer hoop equipment during the lifting process of the steel pipe pile, and the protruding lifting lugs are easily deformed by collision during the transportation of the steel pipe pile, and to provide a steel pipe pile lifting device.

[0006] In a first aspect, the utility model provides a steel pipe pile lifting device, comprising a steel pipe to be lifted, a first lifting rope assembly and a second lifting rope assembly, wherein:

[0010] The steel pipe pile lifting device described in the present application is characterized in that, during construction, the third lifting rope is first extended into the first through hole, the fourth lifting rope is extended into the second through hole, and the fifth lifting rope is extended into the third through hole. Then, the part of the third lifting rope extended into the first through hole is connected to the fourth lifting rope and the fifth lifting rope, and the first lifting rope assembly is connected to the part of the steel pipe to be lifted which is located at a position where the center of gravity is far away from the first through hole. Then, the first lifting rope assembly and the second lifting rope assembly are used to change the steel pipe to be lifted from a horizontal state to a vertical state by first lifting the second lifting rope assembly and then lifting the first lifting rope assembly, or by lifting the second lifting rope assembly faster than the first lifting rope assembly, so that the steel pipe to be lifted can be placed on the piling equipment.

[0017] The first hook extends into the first through hole, the second hook extends into the second through hole, and the third hook extends into the third through hole;
