Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0021] Such as figure 1 As shown, the present invention discloses a triangular truss arm unit body, which includes three main chords 1 arranged in pairs in parallel, the three main chords 1 form a triangular prism structure, and the upper part of the main chord 1 is connected with a top web bar between two pairs 2. The three top webs 2 form a triangular structure perpendicular to the main chord 1, and the bottom webs 3 are connected between two pairs of the lower part of the main chord 1, and the three bottom webs 3 form a triangular structure perpendicular to the main chord 1, Between two main chords 1 there are middle webs 4 repeatedly arranged in a zigzag shape, and the middle webs 4 are loca...

Abstract

The invention discloses a triangular truss arm unit body which comprises three main chord members arranged in parallel pairwise. The three main chord members form a triangular prism structure, a top web member is connected between the upper parts of the main chord members pairwise, and the three top web members form a triangular structure perpendicular to the main chord members. Bottom web members are connected between the lower parts of every two main chord members, the three bottom web members form a triangular structure vertical to the main chord members, middle web members which are repeatedly arranged in a zigzag shape are connected between every two main chord members, and the middle web members are positioned between the top web members and the bottom web members. The invention further discloses a combinable reinforced truss arm which is obtained by combining the triangular truss arm unit bodies. According to the combinable reinforced truss arm and the triangular truss arm unit body thereof, disassembly and assembly are convenient, the structural stability is high, the combination forms are diversified, and the transportation size standard is met.

Description

technical field [0001] The invention relates to a combinable and reinforced truss arm and a triangular truss arm unit body thereof, belonging to the technical field of truss arm structures for crawler cranes. Background technique [0002] The state has invested heavily in large-scale engineering construction projects, and the requirements for hoisting equipment, especially special hoisting equipment, are getting higher and higher. As a representative of the hoisting industry, crawler cranes are mostly related to their own jibs. The jib of crawler cranes generally adopts a single lattice jib, while super-large tonnage crawler cranes mostly use two lattice jib structures with quadrilateral parallel cross-sections or single and double jib combined jib structures. [0003] This kind of jib combined structure is large in size, weak in structural stability, difficult to disassemble and transport, and limited by the quadrilateral truss arm structure, its combination form is relati...
