Embodiment Construction

[0037] A jacking system and a tower crane dismantling method proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0038] Such as Figure 1-8 As shown, the present invention provides a jacking system for jacking the hoisting wire rope 4 of the tower crane demolition device 6, the jacking system is installed on the floor, and includes a guiding part 1, a jacking part 2 and a supporting part 3. The guide part 1 is fixed on the floor, and one end of the support part 3 is connected to the guide part 1 and can move along the guide part 1 toward or away from the lift...

Abstract

The invention provides a jacking-extending system and a tower crane dismantling method. The jacking-extending system is used for jacking and extending a lifting steel wire rope of a tower crane dismantling device and mounted on a floor. The jacking-extending system comprises a guide component, a jacking-extending component and a supporting component, wherein the guide component is fixed to the floor; the supporting component can move along the guide component in the direction close to or away from the lifting steel wire rope; one end of the jacking-extending component is fixedly connected with the other end of the supporting component; a guide pulley system is arranged at the other end of the jacking-extending component and comprises a pulley; the pulley can make contact with the lifting steel wire rope and push the lifting steel wire rope to move in the direction away from the guide component, and the lifting steel wire rope can slide along the pulley. The jacking-extending system can increase the lifting radius of the tower crane dismantling device without affecting the lifting performance of the tower crane dismantling device, thereby being applied to tower crane dismantling under the working environment with the non-step continuous building elevation greatly shrinking.

Description

technical field [0001] The invention belongs to the field of building construction, and relates to a jacking system and a tower crane dismantling method. Background technique [0002] When dismantling a large tower crane on the top of a super high-rise building, the process is relatively simple and the construction period is short. The general dismantling method is: after the construction of the large tower crane completes the building structure, find a corresponding flat position on the top, and directly arrange a small tower crane and A roof crane that can be dismantled by itself can be dismantled in order "from big to small", without any replacement or auxiliary measures. However, such methods and process steps are very suitable for large-scale tower crane demolition under the engineering environment characteristics of simple building top structure, flat structure plane, and small shrinkage of building facade. [0003] However, the above demolition method cannot satisfy ...
