specific Embodiment example 1

[0038] The invention proposes a method for strengthening the bulge of a suspended rectangular steel coal hopper. In the area where the stress of the conventional suspended rectangular steel coal hopper (that is, welded and fixed with the embedded parts of the upper frame) is the largest, by arranging a reinforcing ring and an inner cable, the shortening is shortened. And change the supporting distance of the steel coal hopper wall in this area, so as to reduce the stress and deformation in this area and achieve the purpose of saving steel.

[0039] A method for strengthening the bulge of a suspended rectangular steel coal hopper, the specific steps are as follows:

[0040]Data collection: On-site investigation, collection of construction drawings, collection of design documents for steel coal scuttles with "bulges", mastering their specific dimensions, materials, and loads, and collecting structural design parameters of steel coal scuttles 1;

[0041] Through on-site investiga...

[0065] A method for strengthening the bulge of a suspended rectangular steel coal hopper, the specific steps are as follows:

[0066] Data collection: On-site investigation, collection of construction drawings, collection of design documents for steel coal scuttles with "bulges", mastering their specific dimensions, materials, and loads, and collecting structural design parameters of steel coal scuttles 1;

[0067] Calculation and analysis: According to the data that has been obtained, the finite element structure calculation software is used for modeling analysis to obtain the stress situation and specific location of the "bulge" area of ​​the steel coal hopper;

Abstract

The invention discloses a suspension type rectangular steel coal bucket bulge reinforcing method. The suspension type rectangular steel coal bucket bulge reinforcing method comprises the steps of datacollection, calculation analysis, reinforcement scheme design, reinforcement model verification and practical application. According to the suspension type rectangular steel coal bucket bulge reinforcing method, the problems of stress and large deformation existing in the local area of the coal bucket can be easily solved, and therefore the purposes of optimized design and use of the steel coal bucket are achieved; and the tension of an inhaul cable is uniformly transferred to the wall of the coal bucket through the added reinforcing ring, the non-supporting length of the steel coal bucket wall can be effectively reduced, so that the local stress and deformation of the steel coal bucket are improved, the newly added structure involved in the method is convenient to replace and can be rapidly maintained, and the quick repair is an important design concept of a power plant.

Description

technical field [0001] The invention relates to the technical field of industrial structures, in particular to a method for reinforcing the bulge of a suspended rectangular steel coal bucket. Background technique [0002] Suspended rectangular steel coal scuttles are widely used in thermal power plants. Steel coal scuttles generally use steel plates with a thickness of 8 to 14 mm as the wall, and angle steel or I-steel stiffeners are set on the outside. Since the pressure of the storage material increases closer to the lower end, in the case of usually close to uniformly distributed stiffeners, the part of the hopper wall with the largest inclination angle of the coal hopper is often the area with the highest stress, and in severe cases, it will protrude outward to form a "bulge". After the finite element calculation and analysis of the rectangular steel coal scuttle, it is found that there is a pot-shaped area with the largest stress at the height of the hopper wall with th...
