Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] like Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, the tower crane climbing frame includes a climbing surface 10 and an introduction surface 20 arranged oppositely, and two connecting surfaces 30 connected between the climbing surface 10 and the introduction surface 20, the climbing surface 10, the introduction surface The surface 20 and the two connecting surfaces 30 are detachably connected through four main chords. Wherein the climbing surface 10 and the introduction surface 20 each comprise at least one set of sheet structures, which are integral structures and detachably connected to the main chord. The two connection surfaces 30 can be welded tog...

Abstract

The invention provides a tower crane climbing frame and a tower crane comprising the same. The tower crane climbing frame comprises a climbing surface (10), a lead-in surface (20) and two connecting surfaces (30). The climbing surface (10) is connected with the lead-in surface (20) via the two connecting surfaces (30), the climbing surface (10), the lead-in surface (20) and the two connecting surfaces are connected via a main chord, each of the climbing surface (10) and the lead-in surface (20) comprises at least one group of flaky structures, and the flaky structures are integral and are detachably connected onto the main chord. A mounting structure of the climbing frame can be simplified, the occupied space of the climbing frame in a conveying process is reduced, and mounting efficiency is improved.

Description

technical field [0001] The invention relates to the field of construction hoisting machinery, in particular to a tower crane climbing frame and a tower crane including the climbing frame. Background technique [0002] There are two types of existing tower crane climbing frames. The first type is a rod structure. In this structure, all the webs and jacking beams are connected to the main chord by pins or bolts. , so it can be disassembled into a single-rod structure during transportation, which can save a lot of transportation space and reduce transportation costs. However, when the pole structure is installed on the construction site, because there are too many assembly units and many similar structures, it is difficult to identify, so the assembly is more troublesome and the assembly efficiency is low, which seriously affects the efficiency of installation and disassembly. [0003] The second is to adopt a monolithic structure. The web on the lead-in side of this structur...
