Problems solved by technology

[0002] Due to its simple structure, convenient transportation, fast erection, large load capacity, good interchangeability and strong adaptability, Bailey sheets are widely used in bridge construction, but there will be many inconveniences in the demolition process. The demolition of the Bailey piece is generally carried out by truck crane, but the truck crane needs a wider site for erection, especially in some places where the construction site is narrow, it is more difficult to implement, so the existing technology needs further improvement

Abstract

The invention belongs to the technical field of detachment of beret pieces of cast-in-situ box girders, in particular to a simple lifting device for detaching beret pieces of a box girder and a method. The simple lifting device for detaching the beret pieces of the box girders comprises a main beam, wherein the fixed end of the main beam is connected with the top part of the box girder; the suspending end of the main beam extends out of the box girder; the length direction of a main beam is vertical to the length direction of the cast-in-situ box girder; a first fixed pulley and a second fixedpulley are sequentially arranged on the main beam from the suspending end to the fixed end; a reserved hole is formed in one side of the second fixed pulley; a first winch and a second winch are fixedly arranged on the main beam. The simple lifting device has the advantages that the detachment efficiency is high, and the convenience in use is realized.

Description

technical field [0001] The invention belongs to the technical field of dismantling equipment for cast-in-place box girder beylets, in particular to a simple lifting device and method for removing box girder beylets. Background technique [0002] Due to its simple structure, convenient transportation, fast erection, large load capacity, good interchangeability and strong adaptability, Bailey sheets are widely used in bridge construction, but there will be many inconveniences in the demolition process. The demolition of Bailey pieces is generally carried out by truck cranes, but truck cranes need a wider site for erection, especially in places where some construction sites are narrower, it is more difficult to implement, so the existing technology needs further improvement. Contents of the invention [0003] The object of the present invention is to provide a simple lifting device and method for dismantling the Bailey sheet group of the box girder with high disassembly effic...
