Problems solved by technology

In addition, the existing climbing frame is either integral or detachable, but the degree of detachment varies. Generally, it can only be disassembled into a K-shaped sheet. inconvenient
[0003] As for the super-large luffing jib tower crane, due to its large lifting moment, the height and width of the standard section are required to be large. When designing the climbing frame, in order to adapt to the standard section, the height of the entire cuboid frame structure The size and width of the climbing frame are very large, resulting in a large space occupied during transportation, which cannot meet the size requirements of container transportation. Moreover, due to the integral structure of the climbing frame, the assembly during transportation is also very inconvenient, and the space cannot be used effectively. , leading to an increase in transportation costs

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] Such as Figure 1 to Figure 8 As shown, according to the embodiment of the present invention, the tower crane climbing frame includes four main chords A, B, C, D and eight main beams 30 arranged parallel to each other, and the main beams 30 are divided into two groups, with four in each group. They are respectively set at the two ends of the four main chords A, B, C, and D, and fixedly connected to the four main chords A, B, C, D, the four main chords A, B, C, D and the eight main chords The beam 30 surrounds a cuboid frame. Among them, the four main chords A, B, C, and D are fixed with a plurality of ear plates with pin holes, which are convenient for connection during the assembly process ...

Abstract

Disclosed are a tower crane mast and a tower crane containing the tower crane mast. The tower crane mast comprises: a cuboid frame formed of four main chords (A, B, C, D) and a main beam (30); a first elevation mechanism (10) disposed between two main chords (A, B) at one side of the cuboid frame. The four main chords (A, B, C, D) and the main beam (30) are connected in a separable and detachable manner. The tower crane mast can be detached into separate chord or beam structures during transportation, which facilitates installation and placement and effective use of space, so as to reduce unnecessary space occupation and lower the transportation cost.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a tower crane climbing frame and a tower crane including the tower crane climbing frame. Background technique [0002] Existing climbing frames generally have a single-side jacking structure, mainly because the upper load of the climbing frame is small when the climbing frame is jacked up, and the single-side jacking is enough to meet the requirements of use, and the climbing action of the climbing frame can be realized. In addition, the existing climbing frame is either integral or detachable, but the degree of detachment varies. Generally, it can only be disassembled into a K-shaped sheet. inconvenient. [0003] As for the super-large luffing jib tower crane, due to its large lifting moment, the height and width of the standard section are required to be large. When designing the climbing frame, in order to adapt to the standard section, the height of the entire cuboid frame ...
