Background
The three-pile jacket is an important infrastructure for offshore wind power construction, consists of hollow leg columns and longitudinal cross rods for connecting the leg columns, is a connecting section of an underwater pile foundation of an offshore wind tower and an upper tower cylinder, is generally 90-110 m in height and is generally 2400-2700 tons in weight, a large-scale floating crane ship is adopted for hoisting the jacket, and hoisting points on the upper portion of the jacket are generally arranged at three points, so that the three-pile jacket is symmetrical relative to the center of gravity, is convenient to process and saves cost. The existing hoisting method adopts three supporting beams to form a triangular structure for hoisting, and slings are respectively added in the horizontal direction and the inclined direction of a hoisting hook of a floating crane to control the stress balance, so that the hoisting method has the defect that the self height of the hoisting tool is very high, the hoisting of a three-pile jacket with higher height cannot be met, or the floating crane with higher hoisting height is replaced, and the hoisting cost is increased. Therefore, the low-space suspension type three-pile jacket hanger is designed to reduce the height of the hanger, balance the lifting hook of the floating crane ship to enable the lifting hook to be stressed equally, quickly connect the hanger with the hanging point of the jacket, ensure the lifting safety, reduce the manufacturing cost and improve the working efficiency.
Disclosure of Invention

The utility model discloses a low-space suspension type three-pile jacket hanger, which comprises: three cantilever beam, central body, first upper beam, second upper beam, switching roof beam and two string rope roof beams, wherein: the central body is a cube with three same corners cut on the section of an equilateral triangle, the three corners cut on the central body are respectively fixed with three same cantilever beams through bolts, one cantilever beam is connected with the center of one end of the transfer beam through a first hinge, the symmetrical two sides of the other end of the transfer beam are respectively connected with the symmetrical two sides of the first upper beam through the first hinge, the symmetrical positions of the other two cantilever beams are respectively connected with the symmetrical two sides of the second upper beam through second hinges, the first upper beam and the second upper beam are parallel to each other and fixed together through bolts, the connecting line of the fixed positions of the first upper beam and the second upper beam passes through the central point of the central body, the symmetrical positions of the two sides of the upper ends of the first upper beam and the second upper beam are respectively provided with a rope hanging beam through an end connecting shaft, and the symmetrical two ends of the rope hanging beam are respectively provided with a first hanging shaft.
The utility model discloses a low-space suspension type three-pile jacket hanger, which comprises: the first upper beam and the second upper beam are parallel to a plane formed by the three cantilever beams.
The utility model discloses a low-space suspension type three-pile jacket hanger, which comprises: and the lower ends of the three cantilever beams are respectively provided with a second hanging shaft.
The utility model discloses a low-space suspension type three-pile jacket hanger, which comprises: and the first hanging shaft and the second hanging shaft are provided with lifting appliances.
The low-space suspension type three-pile jacket hanger ensures that the hanging points are vertically stressed when the three-pile jacket is hoisted on the sea, the hanger is conveniently and quickly connected with the hanging points of the three-pile jacket, meanwhile, the stress of each lifting hook of a floating crane ship is equal, the jacket is stable and safe after being hoisted, the working efficiency is improved, the three-pile jacket can be hoisted in an ultrahigh way under the condition that the hoisting height of the floating crane ship is limited, the waste of a 'big horse-drawn trolley' is avoided, and the hoisting cost is saved. According to the utility model, on the premise of meeting the condition that the stress of the upper lifting hook and the stress of the lower lifting hook are equal, the lifting center is superposed with the vertical line of the gravity center of the lifted object, the self height of the lifting appliance reaches the minimum, the requirement on the lifting space of the floating crane ship is widened in a large range, the requirement on the universality of lifting is realized, and the space conversion between the lifting point of the three-pile jacket and the lifting point of the floating crane is realized.
