1. A multi-tower linkage type aerial hoisting platform, comprising:
four tower crane body lifting/lowering parts respectively disposed in an outer periphery of a building to form a rectangle through enclosure, and comprising a tower crane body and a self-climbing lifting/lowering system that is capable of climbing or descending step by step along the tower crane body;
four tower-crane-body-connected support beams, respectively disposed on two opposite self-climbing lifting/lowering systems, wherein a hoisting platform enclosed by the tower-crane-body-connected support beams is driven by the self-climbing lifting/lowering systems to move up and down synchronously;
auxiliary moving beams, slidably disposed below two opposite tower-crane-body-connected support beams;
primary moving beams, located below the auxiliary moving beams and relatively perpendicular to the auxiliary moving beams, and slidably disposed below other two opposite tower-crane-body-connected support beams, wherein two ends thereof extend out of a frame enclosed by the four tower-crane-body-connected support beams, and lower ends thereof are slidably provided with hoisting trolleys;
four movable tower crane bases, respectively disposed at lower ends of the four tower crane body lifting/lowering parts, comprising movable chassis that are used as movable supports with a variable platform angle and support parts disposed on the movable chassis, wherein four corners of the support parts are respectively provided with rotary drilling fastening parts;
lower ends of the auxiliary moving beams and upper ends of the primary moving beams are connected through moving beam connecting mechanisms, and the auxiliary moving beams are controlled by the moving beam connecting mechanisms to drive the primary moving beams to move along axes of the primary moving beams;
the self-climbing lifting/lowering system comprises a plurality of I-beam standard supports that are spliced and installed along a side surface of the tower crane body and locking systems a and climbing systems disposed on the I-beam standard supports,
two I-beams a are connected through a square steel a and a square steel b, and a formed I-beam track matches four I-beam pulleys b provided for the climbing system;
a lower part of a steel plate is connected to the I-beam a, and an upper part of the steel plate is connected to the locking system a;
the steel plate is provided with a plurality of hinged bases, and three hinged bases located at the lower part are configured to hinge and fasten standard sections at an end of the support beam;
the locking system a comprises a locking system support, the locking system support is a square frame welded by a high-strength steel, the four I-beam pulleys a are disposed at four corner sides of the locking system support, and the four I-beam pulleys a match an I-beam track of the I-beam standard support;
four support bearings are disposed at the bottoms of the four corners of the locking system support and are configured to support and restrain a rotating shaft a and a rotating shaft b;
two ends of the rotating shaft a and two ends of the rotating shaft b are respectively connected to the four support bearings, and two ends inward are connected to a locking push rod a and a locking push rod b respectively, irregular parts provided for two ends of the locking push rod a and the locking push rod b are respectively provided with openings, and the openings are used for clamping cross beams between the I-beam standard supports;
a middle of the rotating shaft a is provided with two connecting rods, the two connecting rods are connected to heads of two short hydraulic cylinder Y-shaped joints, tails of the two short hydraulic cylinder Y-shaped joints are connected to heads of telescopic rods of two short hydraulic cylinders, and the tails of the short hydraulic cylinders are hinged with cross beams of the locking system support through a short hydraulic cylinder hinged base;
the climbing system further comprises a locking system b, the four I-beam pulleys b are connected to upper parts of four I-beam pulleys of the locking system b, and the four I-beam pulleys b match the I-beams a and are configured to move along axes of the I-beams a; and
two long hydraulic cylinder hinged bases a are disposed on a side surface of the square steel a, long hydraulic cylinder hinged bases b are disposed on a side surface of a support cross beam of the locking system b, cylinder body tails of two long hydraulic cylinders are connected to the two long hydraulic cylinder hinged bases b respectively, heads of telescopic ends of the two long hydraulic cylinders are connected to tails of two long hydraulic cylinder Y-shaped joints respectively, and heads of the two long hydraulic cylinder Y-shaped joints are connected to the long hydraulic cylinder hinged bases a respectively.
