Description

Vertical supporting device for power station boiler

Technical Field

The invention relates to a vertical supporting device for a power station boiler, and belongs to the technical field of boiler supporting devices.

Background

In recent years, the power industry in China is continuously and rapidly developed, and the steel structure of a power station boiler is continuously optimized to seek for the benefit and best. The vertical support is used as an important component of a steel structure, and if reasonable consideration is not given in design, difficulty is increased for subsequent production, transportation and installation. The vertical support arrangement is generally designed to be matched with a heating surface pipeline, and in the steel structure design, the vertical support is matched with a beam, a vertical support is matched with a column, a vertical support is matched with a suspender, and the vertical support is matched with the pipeline. The vertical supports in the steel structure are arranged from the first layer to the top layer, the number is large in an accumulated mode, and the importance of the vertical supports can be seen. When the vertical support is installed, the deviation must be strictly controlled in the installation process so as not to generate excessive accumulated deviation from the installation of the beam and cause unnecessary errors.

When the vertical support construction drawing is designed, the vertical support section is generally an I-shaped section formed by splicing steel plates or a box-shaped section, the two ends of which are closed to form the I-shaped section, and the vertical support section is connected with the gusset plates at the two ends through connecting angle steel. Because the vertical support length is generally longer, the welding requirement is higher, the requirement on welding seams in manufacturing is higher, the welding deformation is difficult to guarantee, the manufacturing cost is high, and the manufacturing period is long. The vertical support transmits vertical force of a vertical face, the number of bolts for connecting the axis with the beam and the axis with the column is determined through axial force calculation, the connecting angle steel is connected with the main rod piece and the vertical support through the bolts, holes are formed in two sides of the angle steel, the relative position is guaranteed to be correct, and the manufacturing requirement is high. The existing problems are that the general length of the vertical support is longer, the requirement on the splicing process is higher during production, the welding workload is large, the number of hole groups is large, the requirement on the precision is high, and the manufacturing cost is high. The construction progress of the power plant is not facilitated to be smoothly and orderly carried out (see the figure 1-figure 3).

Disclosure of Invention

The invention aims to solve the problems in the prior art and further provides a vertical supporting device for a power station boiler.

The purpose of the invention is realized by the following technical scheme:

a utility boiler vertical support apparatus, comprising: connecting column, gusset plate, bolt, vertical supporting gusset plate, the tie-beam, square pipe backup pad and splint, spliced pole and tie-beam are right angle shape and are connected, the inboard of spliced pole is fixed with the gusset plate, be connected by the bolt between spliced pole and the gusset plate, the inboard of spliced beam is fixed with the gusset plate, be connected by the bolt between spliced beam and the gusset plate, one side of perpendicular support gusset plate and the gusset plate welding on the spliced pole, the opposite side of perpendicular support gusset plate and the gusset plate welding on the tie-beam, the one end and the perpendicular support gusset plate of splint are connected, the other end and the square pipe backup pad of splint are connected, between splint and the perpendicular support gusset plate, be connected by the bolt between splint and the square pipe backup pad, it makes the side pipe of cutting insert in square pipe backup pad to open on the one end both sides pipe wall of.

The invention adopts the square pipe type vertical support section of the power station boiler, and has the advantages that the main section of the vertical support splicing adopts a hot-rolled section steel square pipe structure directly, so that the welding workload is reduced, the connecting structure is simplified, and a lot of workload is reduced. The problems of complex vertical support section, large welding amount and high labor cost are solved.

The invention has simple operation, and is practical and reliable. Greatly improving the production efficiency and shortening the construction period. The welding amount is reduced, the connection is simplified, the manufacturing cost is reduced, and the installation is convenient.
