A hoisting device and hoisting method for external transportation of super high-rise buildings

Abstract

The invention provides hoisting equipment and a hoisting method for external transportation of a super high-rise building. The hoisting equipment comprises mast lifting devices arranged pairwise; each mast lifting device comprises a fixed mast, an amplitude variable mast, a mast base, a hoisting connecting device, an amplitude variable adjustment hoist, an indoor traction hoist and a winch. The hoisting equipment is mounted, the winches are started to hoist a heavy object to an operation floor and to a place above the ground level of the operation floor, hand chains of the amplitude variable adjustment hoists are pulled, the amplitude variable masts are driven to rotate in the indoor direction and change amplitudes and drive the heavy object to move to the interior, after the gravity center of the heavy object is transferred to the interior, the heavy object is fixedly connected with the indoor traction hoists, hand chains of the indoor traction hoists are pulled and the heavy object is completely transferred to the interior, jack-up hoisting ropes are dismounted, and the heavy object is transported to other positions of the operation floor through a carrying tankette. The hoisting equipment is simple in structure, and can meet the hoisting requirements of floors at different heights and equipment in different sizes, particularly on the working condition that an outdoor site is narrow, the cost is saved, and the construction schedule is accelerated.

Description

technical field [0001] The invention relates to the technical field of high-rise building hoisting, in particular to a hoisting device and a hoisting method for external transportation of super high-rise buildings. Background technique [0002] In order to improve the utilization rate of urban land and save the use of urban land resources, urban buildings are gradually developing towards high-rise and super high-rise buildings. For this kind of buildings, there are many materials and equipment to be transported during the construction process, and a lot of construction waste is generated. In addition, most high-rise and super high-rise buildings have equipment floors, and the electromechanical equipment installed in them is heavy and large in number, which brings huge challenges to transportation. [0003] The traditional method is to rely on the construction general contractor to build a public transportation channel inside the building, or build hoisting equipment such as...

Problems solved by technology

For this kind of buildings, there are many materials and equipment to be transported during the construction process, and a lot of construction waste is generated. In addition, most high-rise and super high-rise buildings have equipment floors, and the electromechanical equipment installed in them is heavy and large in number, which brings huge challenges to the transportation work.

[0003] The traditional method is to rely on the construction general contractor to build a public transportation channel inside the building, or build hoisting equipment such as tower cranes outside; but the former is limited by the structural design and construction cost of the building itself, and the general contractor usually does not consider large-scale The transportation needs of equipment, and the latter also has the defect of site limitation, so the above method can only be used to solve the transportation problem of ordinary building materials, not suitable for the transportation of large electromechanical equipment on the equipment floor

[0004] On the other hand, with the "expansion" of the city, the upgrading and transformation of existing buildings in the old city is also ongoing. The improvement of engineering quality has brought about the upgrading of the electromechanical system. For small equipment and materials, permanent elevators can be used for transportation. The vertical transportation of large-scale equipment is already a practical problem that construction personnel have to face; and the narrow lanes and scattered planning of the old city are not suitable for building large-scale hoisting equipment.

[0005] Chinese patent 201310487539 discloses a hoisting device, which includes a main mast, an auxiliary mast, a luffing machine, a sliding machine nest and a chain block. The sliding machine nest is sleeved on the main mast and can be moved along the The main mast slides, the chain hoist is fixed at one end of the main mast and is connected with the sliding motor nest through a rope, one end of the auxiliary rod is hinged with the sliding motor nest, and the luffing will The other end of the auxiliary rod is connected with one end of the main mast; the purpose of expanding the hoisting range is achieved through this device, so as to solve the problem that the existing hoisting device cannot be operated in a narrow place

[0006] Although the above-mentioned patent solves the problem of site limitation, after the equipment is vertically transported to the operation floor, it needs to be safely and securely transferred indoors, and the structure of the hoisting device itself is fixed, which is suitable for general use in buildings with different storeys. The adaptability is not good, and at the same time, the stress points of the main mast, auxiliary mast and main hoisting system are less, and the overall stability of the device needs to be improved

In view of the above considerations, the existing hoisting methods can no longer meet the requirements of use, and a breakthrough must be found to develop a safe, efficient, and practical high-rise building hoisting equipment
