Problems solved by technology

[0003] In the existing tower crane tie rod attachment frame structure, the two ends of the tie rod are welded and fixed to the attachment frame and the boom end respectively. The strength of the welded structure is not strong enough to meet its strength standard, and there is a great safety risk. Moreover, the length of the tie rod of the attachment frame cannot be adjusted according to different installation environments, which is inconvenient for operation and application, and the efficiency of installation and use is low

Embodiment

[0022] According to the recovery capacity requirements of the construction site machinery, a QTZ125 tower crane is required. The tower is mounted in the north side of the main building 4.5m, according to its construction characteristics and models of QTZ125 tower cranes, Vertical lifting equipment for this engineering building material. The tower machine has a power condition of 50 meters and a maximum amount of 1.3 tons. The independent height is 45 meters and the maximum adheres is 180 meters. At the last attachment (seventh), it is installed in about 135m of the building, the vertical distance of the building is 6.45m.

[0023] like Figure 1-2 As shown, a QTZ125 tower attached to the wall of the attachment device, the adhesion device consists of two sets of frame beams and four adhesion struts; the two frame beams are fastened by 24 sets of M27 bolts, nuts, and gaskets. Adhesive frame, four vertices on the attachment frame therethrough, hinged, the ends of the four adhesion str...

Abstract

The invention discloses an attaching device for attaching a tower crane to a wall and a mounting process thereof. The attaching device is composed of two sets of frame beams and four attachment supporting rods. The two sets of frame beams are fastened into an attachment frame through 24 sets of M27 bolts, nuts and gaskets, four attachment supporting rods are arranged at the four vertexes of the attachment frame and hinged to the attachment frame, connecting sleeves are arranged at the ends of the four attachment supporting rods and hinged to connecting bases at the attachment positions of a building, the four supporting rods should be kept in the same horizontal plane, and the four attachment supporting rods are arranged on the same horizontal plane. The inner supporting rods can be pushed to abut against the four main chord members of the tower body through the adjusting bolts. The device is simple in structure and convenient to assemble and install, the installation efficiency of the adjustable pull rod attachment frame structure of the tower crane is improved, and the labor cost and the time cost are greatly saved.

Description

Technical field [0001] The present invention generally relates to a tower attachment device and its mounting process thereof. Background technique [0002] Tower cranes are the main equipment for vertical transportation and lifting in construction. When the tower crane is installed more than a certain height, in order to ensure the safety of the tower crane, the attachment device must be installed to achieve the fixation of the tower crane. [0003] The tower cradle tie rod adhesive structure in the prior art is that both ends of the tensile rod are fixed to the attachment frame and the boom end, and the strength of the welding structure is not strong. There is a big safety risk. It is not possible to adjust the length of the attached sheller according to different installation environments, and the operating application is inconvenient, and the installation is low. [0004] The attachment frame of the present invention is that the tower has reached the free height limit and need...
