Description

Technical Field

[0001] The utility model belongs to the technical field of lifting devices, in particular to an offshore wind power tower lifting device. Background Art

[0002] The wind turbine tower is the tower pole for wind power generation. It mainly plays a supporting role in the wind turbine generator set and absorbs the vibration of the unit.

[0003] When hoisting an offshore wind turbine tower, a hoisting mechanism is required. During the hoisting process, it is mostly lifted and lowered by steel cables. Due to the large mass of the wind turbine tower, the steel cables will shake significantly during the hoisting process, thus causing safety hazards. In order to solve the above problems, an offshore wind turbine tower hoisting device is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide an offshore wind turbine tower lifting device to solve the problem that the offshore wind turbine tower needs to be lifted by a lifting mechanism. During the lifting process, the tower is mostly lifted and lowered by a steel cable. Due to the large mass of the wind turbine tower, the steel cable will shake significantly during the lifting process, thereby causing a safety hazard.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an offshore wind power tower lifting device, comprising a lifting platform, a steel cable and a lifting plate, the bottom end of the steel cable is fixedly connected to the lifting plate, one surface of the lifting platform is fixedly connected to a connecting rod, one end of the connecting rod is fixedly connected to a second traction ring, the upper surface of the lifting plate is fixedly connected to a first traction ring, the upper surface of the first traction ring is provided with a first traction groove, the upper surface of the second traction ring is provided with a second traction groove, the steel cable passes through the first traction groove and the second traction groove, the upper surfaces of the lifting plate, the first traction ring and the second traction ring are all provided with slots, an anti-sway bar is installed in the slot, the peripheral side of the anti-sway bar is provided with a plurality of positioning grooves, and a positioning block is installed in the positioning groove.

[0007] Preferably, the plurality of positioning grooves are linearly arranged on the peripheral side surface of the anti-sway bar.

[0008] Preferably, a plurality of balls are connected to the peripheral side surface of the inner wall of the second traction groove, and the balls are rotatably connected to the second traction ring.

[0009] Preferably, the anti-sway rod is in sliding engagement with the slot, and the positioning block is in sliding engagement with the positioning groove.

[0010] Preferably, a hook is fixedly connected to the bottom surface of the lifting plate.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model provides an anti-sway bar, a first traction ring and a second traction ring. The diameter of the wind turbine tower is about seven meters. When the wind turbine tower is hoisted, its height from the ground shall not exceed 0.5 meters. The lifting platform lowers the steel cable. When the lifting plate is close to the ground, the staff selects an anti-sway bar with a length of about fifteen meters and inserts it into the slot. Due to the setting of the positioning funnel, the positioning funnel is large at the bottom and small at the top, which makes it convenient for the anti-sway bar to be inserted into the slot of the second traction ring, so that the position of the positioning groove of the first traction ring is adapted to the position of the positioning groove on the side surface of the first traction ring. Then the positioning block is inserted into the positioning slot to fix the anti-sway bar. The anti-sway bar is rigidly set so that the steel cable can be straightened during the lifting of the wind turbine tower. The diameters of the first traction groove and the second traction groove are small, so that the steel cable can only sway slightly in the traction groove, avoiding safety hazards caused by excessive swaying of the steel cable.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example:

[0030] like Figures 1-4As shown, the method of using an offshore wind turbine tower lifting device of the present invention is as follows: when using the present invention, the diameter of the wind turbine tower is about seven meters. When lifting the wind turbine tower, its height from the ground shall not exceed 0.5 meters. The lifting platform 1 lowers the steel cable 2, and the steel cable 2 extends in the second traction ring 6.
