Problems solved by technology

[0002] Tower cranes have a great market prospect in my country's construction field, but most of the tower cranes used in the domestic construction field are fixed-arm tower cranes, which have many disadvantages, and the installation and disassembly of tower cranes also take a lot of time. The construction of low-rise buildings with 3 to 6 floors and factory buildings increases the cost and prolongs the construction period

Embodiment

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] like figure 1 and figure 2 As shown, the present invention includes a liftable tower body 5, a first boom section 38, a second boom section 39, a first boom section upper chord 38a, a second boom section 39a, a boom section assembly, a boom section folding assembly , a support rod assembly, a tie rod assembly, a connection assembly and a power assembly. The lower end of the tower body is fixed to the ground, and the other end is movably connected to the boom; the crane folding assembly is respectively connected to the tower body and the boom section for controlling the folding of the boom section. The top of the tower body 5 is fixedly connected with the first ear plate 1 and is hinged with the second ear plate 3 through the first pin shaft 2 .

[0028] The connecting assembly includes a pin shaft part, lug part and pulley part, the pin shaft part includes...

Abstract

The invention provides a tower type crane with double hoisting arm sections. The tower type crane comprises a tower body, a first arm section and a second arm section, wherein the first arm section is connected with the tower body, the second arm section is connected with the first arm section, and a folding mechanism is arranged between the first arm section and the second arm section; after being folded, the first arm section and the second arm section are in a level adjacent state under the effect of the folding mechanism. Compared with an old fixed hoisting arm tower machine, hoisting arms are mutually hinged and folded together through the folding mechanism, so that the transporting height is reduced, and the tower type crane is convenient to transport; the hoisting arm can be orderly unfolded from a folded state to the level state under the effect of a power system, the mounting time of the tower machine is greatly shortened, and the cost of a low-rise building and a plant building is reduced.

Description

technical field [0001] The invention relates to an engineering equipment, in particular to a tower crane with double jib sections. Background technique [0002] Tower cranes have a great market prospect in my country's construction field, but most of the tower cranes used in the domestic construction field are fixed-arm tower cranes, which have many disadvantages, and the installation and disassembly of tower cranes also take a lot of time. The construction of low-rise buildings with 3 to 6 floors and factory buildings increases the cost and prolongs the construction period. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a folding mechanism and unfolding method for the double jib sections of a tower crane in view of the deficiencies in the prior art. [0004] In order to solve the above technical problems, the present invention provides a tower crane with double jib sections, comprising...
