Embodiment Construction
[0056] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0057] like figure 1 as shown, figure 1 It shows an auxiliary dismantling device for dismantling the arm of a luffing tower crane provided by an embodiment of the present invention. The auxiliary dismantling device is a frame structure. In the accommodation space of any section of the boom of the telescopic tower crane, the two ends of the accommodation space respectively have a first opening and a second opening, and the bottom forms a third opening for hanging the jib section, wherein the The above-mentioned first opening is used for fixed connection with a set jib section.
[0058] Specifically, the frame structure includes an upper frame 15, a left frame ...

The invention discloses an arm detaching method for a swing arm tower crane and an auxiliary detaching device. The arm detaching method comprises the steps of bushing the auxiliary detaching device on a lift arm, and fixing a first opening of the auxiliary detaching device, close to a tower body, on the lift arm; detaching the section of lift arm in the auxiliary detaching device and hanging the lift arm on a placing surface; sliding the lift arm connected to end section of lift arm towards the inside of the auxiliary detaching device; detaching each section of lift arm sliding into the auxiliary detaching device until the length of rest lift arms is less than a preset length; and fixedly connecting the rest lift arm, and detaching the auxiliary detaching device. The arm detaching method disclosed by the invention has the beneficial effects of being capable of finishing the lift arm detaching work through the auxiliary detaching device and a lifting mechanism on the swing arm tower crane without other lifting devices, and thus the detaching expense is reduced; and simultaneously, the lift arm can be detached in a relatively narrow working environment, so as to facilitate the detaching of the lift arm.
Description
technical field [0001] The invention relates to the technical field of engineering equipment, in particular to a boom dismantling method and an auxiliary dismantling device of a boom tower crane. Background technique [0002] With more and more super high-rise buildings, jib tower cranes are used more and more frequently. During the use of the luffing jib tower crane, when the tower crane is dismantled and when different jib lengths are required, it is necessary to hoist the jib as a whole. As the heaviest part of the tower crane, the boom often needs to use other lifting equipment, such as roof cranes, truck cranes or other lifting equipment, to remove the boom as a whole. The cost of lifting and dismantling is relatively high. And in some special occasions, when the construction site cannot be reached due to the layout of the site or the inaccessibility of other lifting equipment, it will not be possible to remove the boom or reduce the boom section of the boom.
