[0001] The invention relates to the technical field of offshore construction steel casing hoisting equipment, in particular to offshore construction steel casing hoisting equipment. Background Art

[0002] Offshore construction steel casing hoisting equipment is a special equipment used for installing steel casing at sea. Steel casing is usually used in offshore wind power foundation, bridge pile foundation, wharf construction and other projects to protect pile foundation, prevent seawater erosion and provide construction platform.

[0003] In the prior art, offshore construction steel casings are usually installed by a crane ship in conjunction with a crane as a lifting device for construction. The crane is connected to the steel casing by tying a steel wire rope to the steel casing, thereby enabling the crane to lift the steel casing.

[0004] However, in the prior art, after the steel casing is hoisted, due to the strong offshore wind and the lack of limit stops, the steel casing may swing. When docking with the support column, the position of the steel casing needs to be repeatedly adjusted for docking, which takes a long time and has low docking efficiency. Summary of the invention

[0014] Preferably, a fixing hole is provided on one side of the winding capstan, and the rotation of the first bevel gear can be fixed by inserting a fixing screw into the overlapped position of the limiting hole and the fixing hole provided on the extension plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The invention provides an offshore construction steel casing lifting equipment. When the steel casing is lifted, the connecting seat is first connected to the crane through the connecting hook on the top of the connecting seat, and then the clamping plate arranged at the bottom of the connecting seat is sleeved on the four sides of the steel casing by the crane. Then, according to the length of the steel casing, the telescopic length of the telescopic clamping plate is adjusted so that the clamping plate and the telescopic clamping plate surround the steel casing more than half of the length of the steel casing. Then, the motor at the top of the supporting plate outside the top of the clamping plate starts to control the rotation of the rotating shaft, and the rotating shaft drives the telescopic rotating shaft plugged in the bottom of the rotating shaft to rotate synchronously, so that the rotating shaft and the second bevel gear arranged on the telescopic rotating shaft rotate synchronously, and the second bevel gear starts to mesh with the first bevel gear connected to the winch rotating shaft outside the winding winch, so that the winding winch starts to rotate, and the winding winch starts to drive the tightening rope fixed on the winding winch to be wound, and while the tightening rope is wound, the three sets of clamps are pulled through the through hole. The holding plate and the telescopic clamping plate shrink synchronously, and at the same time drive the sliding rollers on both sides of the plug-in block to slide quickly in the clamping groove at the bottom of the connecting seat, so that the clamping plate and the clamping ring on the inner side of the telescopic clamping plate can hold steel casings of different diameters. At the same time, the steel casing is prevented from swinging due to excessive wind force. The surface of the clamping ring is provided with anti-slip grooves, and the anti-slip grooves can resist the downward sliding of the steel casing to prevent the steel casing from slipping. The outer side of the clamping ring on the inner side of the telescopic clamping plate is at the same horizontal line as the clamping ring on the inner side of the clamping plate, so that the clamping ring on the inner side of the telescopic clamping plate and the clamping ring on the inner side of the clamping plate can be tightly attached to the surface of the steel casing at the same time. Then, the fixing screw is inserted into the limiting hole on the extension plate connected to the outer side of the first bevel gear that coincides with the fixing hole on one side of the winding winch surface, and the rotation of the first bevel gear is fixed, so that the first bevel gear synchronously fixes the rotation of the winding winch, and prevents the winding winch from loosening, resulting in the clamping falling off.
