Four-dimensional adjusting attachment device for connecting attachment type tower body and building

Abstract

The invention discloses a four-dimensional adjusting attachment device for connecting an attachment type tower body and a building, and belongs to the technical field of hoisting machinery. The attachment device comprises a square attachment frame and a plurality of connecting rod assemblies, wherein the square attachment frame is formed by buckling two symmetrical C-shaped half frames, combining the C-shaped half frames in a flange and bolt matching manner and then sleeving the periphery of a tower body attachment joint, the connecting rod assemblies are supported between the building and the square attachment frame, and the two ends of each connecting rod assembly are hinged to the building and the nearest outer side face of the square attachment frame correspondingly; and eight jacking screws of which the inner ends are clamped and embedded into a main chord member of the tower body attachment joint and the outer ends horizontally penetrate through four side surfaces of a frame respectively are arranged at four corners of an inner cavity of the square attachment frame. The attachment device can slide up and down, can properly rotate and change the connection length, meets the free adjustment requirements of the attachment height and the attachment distance, can adapt to frequent transition and repeated use, avoids installation interference and serious deformation, and is wide in application range, high in flexibility, easy to operate, convenient to use, comprehensive in function, high in safety, light in weight, economical and practical.

Description

technical field [0001] The invention belongs to the technical field of hoisting machinery, and more specifically relates to a four-dimensional adjustment attachment device connecting an attachment tower body and a building. Background technique [0002] Tower cranes are more and more widely used in electric power, metallurgy, petrochemical, construction and other industries, especially self-elevating tower cranes are more common. The tower body of the self-elevating tower crane works by standing vertically on the ground. The tower body can be divided into attached tower body (the tower body is connected with nearby buildings), self-supporting tower body or non-attached tower body according to different types and uses. There are two types of attached tower body (the tower body is not connected to nearby buildings). Due to the increased lateral support of the attached tower body, according to the metal structure design theory, the attached tower body has more reasonable force...

AI Technical Summary

Problems solved by technology

During the use of this traditional attachment device, the following shortcomings were found: the installation height and installation distance cannot be adjusted, and the height and strength requirements of the attachment point are very strict, resulting in very poor installation mobility; and the length of the attachment rod is fixed, It cannot be reused if the attachment distance is slightly changed when the construction site is changed, and the adaptability is poor. In addition, the factor of the sinking of the tower body will cause interference and serious deformation of the attachment device, and poor safety.
