Embodiment Construction

[0031] The present invention will be further illustrated below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0032] Such as Figures 1 to 3 As shown, the embodiment of the present invention provides a self-dismantling device for the upper structure of a crane. The mechanism includes a pole 1, a hoist 2, a bracket 3, a hoisting wire rope 4 arranged on the hoist 2, a luffing wire rope 5 and a chain hoist 6 , The main part of the grill bar 1 is a frame structure, so that the grill bar 1 is light in weight and easy to carry, install and disassemble. The grill bar 1 includes several main poles 11 and a plurality of support poles 12 connected between the main poles 11 . Can adopt welding or bolt to...

Abstract

The invention discloses a self-disassembly device of an upper mechanism of a crane, the crane and a self-disassembly method. The device comprises a derrick mast, a hoist, a support, a lifting steel wire rope arranged on the hoist, an amplitude-variation steel wire rope and a pull calabash. A hinge part is arranged at the lower end of the derrick mast, a first pulley is arranged at the upper end ofthe derrick mast, and a second pulley is arranged on the support; the lifting steel wire rope penetrates through the first pulley, a lifting hook is connected to the outer end of the lifting steel wire rope, and one end of the amplitude-variation steel wire rope is connected to the upper side of the derrick mast, penetrates through the second pulley and is connected with the pull calabash. According to the self-disassembly device, the derrick mast is stable in structure and low in weight and is conveniently assembled and disassembled on the tower crane during disassembly, the pull calabash can be adopted for the derrick mast for amplitude-variation adjustment, the device can adapt to disassembly of different parts and is easy to operate and convenient to use, the \ time of disassembling the tower crane is greatly shortened, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of flat-topped tower cranes, in particular to a self-dismantling device for a crane upper mechanism, a crane and a self-dismantling method. Background technique [0002] Traditional topless tower cranes lower the tower by themselves, and then remove all its components by other auxiliary cranes. However, in some special cases where space is limited due to closed venues and steel structures, the crane cannot complete the self-lowering procedure, and the auxiliary crane will also be difficult to disassemble due to site and height constraints. Contents of the invention [0003] The object of the present invention is to provide a self-dismantling device for the upper structure of a crane, a crane and a self-dismantling method in view of the deficiencies in the prior art. [0004] In order to achieve the above object, in the first aspect, the present invention provides a self-dismantling device for the upper structure of...
