Embodiment Construction

[0017] Now in conjunction with the accompanying drawings and embodiments, the method of assembly and hoisting of the bridge crane in the factory building under the closed environment proposed by the present invention will be further described in detail.

[0018] According to the present invention, a method for assembling and hoisting an bridge crane in a workshop in a closed environment, said assembling and hoisting includes the following steps:

[0019] 1) Preparations before construction: conduct a second retest on the driving beam track of the original factory building, clean up the hoisting ground site at the same time, and inspect the installation tools;

[0020] 2) Assembly of the main beam: adjust the height of both ends of the main beam to make them equal, measure the camber and side camber, and then assemble the accessories on the main beam to the specified position of the main beam;

[0021] 3) Hoisting of the main beam: the main beam includes A main beam 1 and B mai...

Abstract

The invention discloses an inside assembly lifting method of a bridge crane in a factory building under a closed environment; and the assembly lifting method comprises the steps of: construction preparation; assembly of a main beam; lifting of the main beam; lifting of a main trolley; and lifting completion. The assembly lifting is performed under the condition of not damaging an original factory building structure, so that the investment cost, the manufacturing cost and the safety cost caused by the disassembly work can be effectively reduced; the construction efficiency can be effectively improved; and the quality and the safety are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a span-internal assembly and hoisting method of a bridge crane in a factory building in a closed environment. Background technique [0002] With the development of society and the continuous upgrading of industrial technology, enterprises must optimize and upgrade the existing production layout if they want to achieve greater development, resulting in an increase in output and the need to increase lifting equipment. Adding lifting equipment needs to be installed in the original factory building, and the original factory building structure cannot be damaged twice; at the same time, the bridge crane is installed in the original factory building, and the large crawler hoisting equipment cannot display its application functions and effects; There are many factors such as the production rhythm that cannot guarantee the smooth installation, the increase of saf...
