Description

Tower crane embraces tile connection structure Technical Field The utility model relates to a tower crane tile holding connection structure, and belongs to the technical field of tower cranes. Background The tower body of the tower crane is formed by connecting a plurality of standard sections, each adjacent standard section of the tower body is connected with each other through a joint on a main chord member, and the standard section joint of the common tower crane can be generally divided into three connecting modes of high-strength bolt connection, pin shaft connection and holding tile connection according to the difference of the standard section joint connecting pieces. The enclasping tile structure is widely applied to the connection of the standard tower section of the self-elevating tower crane, and the main chord joint of each two standard tower sections is connected. The traditional tile holding device needs to be detached in the standard knot mounting and dismounting process, the weight of the large tower tile holding device is about 50kg or more, the detachment and the transportation are troublesome, the time and the labor are wasted, and the tower body mounting efficiency is reduced. Disclosure of utility model In order to overcome the defects in the prior art, the utility model provides the tower crane tile holding connecting structure, in which the tile holding device can be opened and closed in a rotating way, and the tile holding device is only required to be mounted on the main chord connector below for the first time, and is not required to be carried and dismounted in the later stage, so that the problem of frequent dismounting of the tile holding device is solved. The tower crane holding tile connecting structure comprises a standard joint lower connector, a standard joint upper connector, a holding tile I and a holding tile II, wherein a hinge I is arranged on the standard joint lower connector, a hinge II is arranged on the holding tile I, a hinge III is arranged on the holding tile II, the hinge II and the hinge III are connected with the hinge I through a connecting rod, and the holding tile I and the holding tile II are connected and fixed with the standard joint lower connector and the standard joint upper connector through bolts. The standard joint lower connector and the standard joint upper connector are provided with grooves matched with the holding tile I and the holding tile II, and the holding tile I and the holding tile II can be clamped into the standard joint lower connector and the standard joint upper connector through the grooves. The standard section lower joint is arranged at the top of the standard section, a tray is further arranged on a transverse web member at the top of the standard section, and the holding tile I and the holding tile II can be placed on the tray when opened. The holding tile I can be connected to the lower joint of the standard joint through a hinge I and a hinge II. The holding tile II can be connected to the lower joint of the standard joint through a hinge I and a hinge III. And 4 bolt holes are respectively formed in the holding tile I and the holding tile II, and when the holding tile I and the holding tile II are installed, two sides of the holding tile I and the holding tile II are fixed through 2 bolts respectively.
