Heavy beam body rolling displacement and fine adjustment positioning device

Abstract

The invention relates to the technical field of building construction, in particular to a heavy beam body rolling displacement and fine adjustment positioning device. The device comprises a fine adjustment positioning assembly, a supporting assembly and a beam moving bearing assembly. The fine adjustment positioning assembly is used for adjusting the lifting height of the supporting assembly. Thefine adjustment positioning assembly comprises two beam positioning blocks which are oppositely arranged; a plurality of transversely-arranged tensioning rods are arranged between the two beam positioning blocks. A beam bearing block is supported between the two beam positioning blocks, the supporting assembly comprises a base plate and U-shaped supporting plates, the beam moving bearing assemblycomprises a mandrel, the two ends of the mandrel are rotationally connected to the U-shaped supporting plates, and the position, located between the two U-shaped supporting plates, of the mandrel is sleeved with a sleeve. According to the heavy beam body rolling displacement and fine adjustment positioning device, displacement of a beam body to be installed is facilitated, fine adjustment positioning of the beam body can be achieved, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a heavy-duty beam body rolling displacement and fine-tuning positioning device. Background technique [0002] With the continuous improvement of national infrastructure, the application of bridges and large-scale building components in the construction process has become increasingly widespread, and the application of advanced construction techniques such as jacking and dragging has gradually become common. However, heavy bridges mainly move beams in the form of sliding At the same time, the support system for the movement of the beam body and the falling beam must be set separately, which makes the construction steps cumbersome, and the operation risk is high. The power required for the displacement and sliding friction of the beam body is large, the operability is not strong, and it is not easy to use . In view of this, we propose a heavy-duty beam rolling displa...
