Embodiment Construction

[0025] Such as Figure 1 to Figure 10 As shown, in an embodiment of the climbing method of an internal climbing tower crane without falling down in the present invention, it includes a tower crane 1, a climbing joint 2, a climbing frame 3, a stirrup 4, a tower crane upper beam 5, a limit guide device 6, a jacking Oil cylinder 7, tower crane middle beam 8, tower crane lower beam 9 and hydraulic control system.

[0026] Such as Figure 2 to Figure 4 As shown, the upper beam 5 of the tower crane, the middle beam 8 of the tower crane, and the lower beam 9 of the tower crane are all well-shaped beams, and the ends of the beams are supported on the main structure. The upper beam 5 of the tower crane, the middle beam 8 of the tower crane and the lower beam 9 of the tower crane are all located on the periphery of the tower crane 1, and are arranged sequentially from top to bottom along the height direction of the tower crane 1. The upper beam 5 of the tower crane is connected with th...

Abstract

The invention relates to an internal climbing tower crane climbing method without using an inverted beam method. Through arranging three support beams and two lifting oil cylinders, an internal climbing tower crane climbs without inversely transporting the support beams. An implement device comprises the tower crane upper beam, the tower crane middle beam, the tower crane lower beam, a climbing frame, the two lifting oil cylinders, a limiting and guiding device, a climbing joint and a hydraulic control system. The method mainly comprises the following steps of balancing a tower crane, and supporting the tower crane middle beam on a main structure; operating the hydraulic control system, stretching the lifting oil cylinders for lifting the tower crane upper beam to lift up, driving the tower crane to lift up at the same time, separating the tower crane upper beam from the main structure, solidifying the tower crane lower beam and the climbing joint, and synchronously lifting the tower crane lower beam and the tower crane; and connecting the tower crane upper beam with the main structure after lifting the tower crane upper beam in place, bearing a load of the tower crane through thetower crane upper beam, separating the tower crane middle beam from the structure, operating the hydraulic control system, contracting the lifting oil cylinders, lifting the tower crane middle beam, and accomplishing one-time climbing after lifting the tower crane middle beam in place.

Description

technical field [0001] The invention relates to building construction machinery technology, in particular to a method for climbing an inner climbing tower crane without falling down a beam. Background technique [0002] At present, in the super high-rise construction technology, the vertical transportation tower crane often adopts the internal climbing tower crane. The climbing process requires the dismantling of the support beam and the climbing frame in the air, reverse transportation to the predetermined floor, and installation, so as to realize the climbing of the tower crane. The transfer process is referred to as " Inverted beam". [0003] The operation of inverting the beam belongs to the high altitude and narrow space operation, and the operator has no reliable protective measures, and there are great safety hazards in the whole process; in the process of inverting the beam, other tower cranes need to be used to cooperate with the construction, which reduces the util...
