Abstract

The utility model relates to a large plate girder support of a large power station boiler. At present, when a plate girder bears a large load and has a long span, the deflection change of the plate girder when the plate girder is bent generates a large girder end corner, at the moment, the girder not only transmits the pressure in the vertical direction to a support but also generates acting force to the side surface of the support, and the corner of the rectangular strip-shaped support can be damaged due to the large load. A large plate girder support of a large power station boiler comprises: the plate beam and the upright post are connected through a group of bolt assemblies, the top of the upright post is connected with the arc support, and the bottom of the plate beam abuts against the arc surface at the top of the arc support; the top of the arc-shaped support is of an arc-shaped structure, and the side surface of the arc-shaped support is of a vertical surface structure. The utility model is applied to the field of boilers.

Description

Large plate beam support for large power station boiler

technical field

The utility model relates to a large plate beam support of a large power station boiler.

Background technique

At present, when the beam is supported above other structures, a support is generally required at the bottom of the beam to transfer the load at the end of the beam to the structure below it. Usually the support is a rectangular strip support, but when the beam bears a large load and has a long span, the deflection change of the beam when it is bent produces a large beam end corner. At this time, the beam transmits the vertical direction to the support. In addition to the pressure, it also acts on the side of the support. Due to the large load, the corners of the rectangular strip support will be damaged.

SUMMARY OF THE INVENTION

The purpose of the utility model is to provide a large plate beam support for a large power station boiler.

The above purpose is achieved through the following technical solutions:

A large plate beam support for a large-scale power station boiler, which is composed of a column, an arc support and a plate beam, the plate beam and the column are connected by a set of bolt assemblies, and the top of the column is connected to the The arc-shaped support is connected, and the bottom of the plate beam abuts on the arc-shaped surface of the top of the arc-shaped support;

The top of the arc-shaped support is an arc-shaped structure, and the side surface is a vertical surface structure.

For the large plate beam support of the large power station boiler, the curvature radius of the arc surface of the arc support is selected according to the size of the plate beam.

The beneficial effects of the present utility model:

1. The utility model is characterized in that the upper surface of the support adopts an arc surface, the radius of curvature of the arc surface can be selected according to needs, and the arc support is still designed to meet the pressure bearing surface of the support. This type of support can meet the requirements of bearing capacity while adapting to the change of different corners of the beam end, so that the support will not be damaged.

2. The utility model can adapt to the change of different corners of the beam end while meeting the bearing capacity requirements, and has strong adaptability. At the same time, since the bearing will not be damaged by the deformation of the corner of the beam end, the life of the bearing is greatly extended.
