Epoxy plaster repaired bridge crane constructing structure and constructing method

Abstract

The invention provides an epoxy plaster repaired bridge crane constructing structure and constructing method. The constructing structure comprises a leveling steel base plate flatly laid on a crane beam, a steel rail flatly laid on the leveling steel base plate and a plurality of pressing devices which are distributed from front to back. An elastic base plate is cushioned between the steel rail and the leveling steel base plate, and a cavity between the leveling steel base plate and the crane beam is filled with epoxy plaster. Each pressing device comprises two flexible pressing plate assemblies which are symmetrically distributed on the left side and the right side of the steel rail. Each flexible pressing plate assembly comprises a lower pressing plate and an upper pressing plate. The constructing method comprises the steps of dismounting an old rail and cleaning the top surface of the crane beam, installing and coarsely adjusting the leveling steel base plate, welding the lower pressing plate, finely leveling the leveling steel base plate, pouring the epoxy plaster, installing the steel rail and installing the upper pressing plate. The constructing method is reasonable in design, convenient to construct, low in investment cost, short in constructing period, good in constructing effect and capable of conveniently and quickly repairing a bridge crane.

Description

technical field [0001] The invention belongs to the technical field of bridge crane track repair, and in particular relates to a construction structure and a construction method for repairing bridge crane track with epoxy glue. Background technique [0002] The bridge crane is the crane used to lift the container for loading and unloading operations on the wharf, and it is the heart of the wharf. The operating capacity of the bridge crane determines the cargo handling capacity of a terminal. In the actual use process, the normal use of the bridge crane track directly determines the bridge crane's operating capacity, but nowadays, after the bridge crane track is put into use, there are often problems such as loose track fasteners, track bending, and track expansion joints, which cause the bridge crane to fail to work normally. Therefore, it is necessary to repair the problematic bridge crane track. For example, the Xinjiang Alashankou container transshipment depot is design...

AI Technical Summary

Problems solved by technology

The container transshipment depot was opened for operation after completion of inspection and delivery in September 2009. At the end of 2011, problems such as loose rail fasteners, curved rails, and top dead rail expansion joints occurred, causing major technical indicators such as rail spacing to exceed the standard, forming a safety hazard. , resulting in the failure of the bridge crane to operate normally, it needs to be rectified

According to the on-site measurement and investigation, the direct cause of the quality defect of the track is the large deviation of the installation of the crane beam and the non-standard installation of the track. The main reason is that the design of the pressure plate and the expansion joint is unreasonable

Due to hidden dangers in track quality that have seriously affected production, it must be dismantled and redone

However, due to the short renovation and construction time, it is impossible to remove the crane girder and redo it. Therefore, there is currently a lack of a structure with reasonable structure design, convenient implementation, low investment cost, short construction period, and good construction effect. The construction method can easily and quickly repair the bridge crane track
