Problems solved by technology

In the prior art, the tower crane is fixed to the main body through multiple sets of tower crane attachment devices. The attachment frame of each set of tower crane attachment devices cooperates with three pull rods to realize connection and fixation with the main building. The attachment frame is set between two standard joint arms of fixed elevation. One end of the tie rod is fixed to the attachment frame by bolts, and the other end of the tie rod is connected to the main building by embedded bolts. However, the number of existing tie rods is three, and the stability of the tower crane is lacking. In addition, the bolts are pre-embedded on the surface of the main building. After the construction is completed, it will cause quality problems such as water leakage at the pre-embedded position

Embodiment Construction

[0016] Such as Figures 1 to 3 shown

[0017] The attachment device includes a standard joint attachment frame 1, four connecting rods and two groups of hoop assemblies.

[0018] The standard section attachment frame 1 adopts a commercially available standard section attachment frame 1, and the standard section attachment frame 1 is fixed between the two standard section arms of the tower crane.

[0019] The two groups of hoop assemblies are the first hoop assembly 2 and the second hoop assembly 3 respectively. The first hoop assembly 2 and the second hoop assembly 3 have the same structure. The first hoop assembly 2 is used as an example to introduce the hoop assembly. The structure of the hoop assembly, the first hoop assembly 2 includes two holding plates 21 and six fixing bolts 22, the two holding plates 21 are respectively close to the two sides of the concrete column 8 of the main building, and the two holding plates 21 are passed through six Two fixing bolts 22 are co...

Abstract

The invention provides a tower crane attachment device. The tower crane attachment device comprises a standard joint attachment frame, four connecting rods and two sets of hoop assemblies, wherein thestandard joint attachment frame is fixed between two sections of standard joint arms of a tower crane; the two sets of hoop assemblies are respectively matched with two concrete columns, close to sides of the joint arms of the tower crane, of a main building; each hoop assembly comprises two holding plates and a plurality of fixed bolts; the two holding plates are connected and fixed by the fixedbolts; the four connecting rods form a group in pair; the two sets of connecting rods are corresponding to the two sets of hoop assemblies; and each set of hoop assemblies are fixed to the standard joint attachment frame by a set of connecting rods. Through the cooperation of the two sets of hoop assemblies and the concrete columns of the main building, the connection and fixation between the tower crane and the main building is realized; after the subsequent completion of the main building, the hoop assemblies only need to be removed without damage to the surface of the main building, so that subsequent leakage problems are avoided; and the fixed structure and the distribution position of the four connecting rods strengthen the stability of the connection between the attachment frame andthe main building.

Description

technical field [0001] The invention relates to a tower crane attachment device. Background technique [0002] Tower crane is the most commonly used type of lifting equipment on construction sites, used to lift steel bars, corrugated wood, concrete, steel pipes and other construction materials for construction. In the prior art, the tower crane is fixed to the main body through multiple sets of tower crane attachment devices. The attachment frame of each set of tower crane attachment devices cooperates with three pull rods to realize connection and fixation with the main building. The attachment frame is set between two standard joint arms of fixed elevation. One end of the tie rod is fixed to the attachment frame by bolts, and the other end of the tie rod is connected to the main building by embedded bolts. However, the number of existing tie rods is three, and the stability of the tower crane is lacking. In addition, the bolts are pre-embedded on the surface of the main bu...
