Description

Technical Field

[0001] This application belongs to the technical field of boiler headers, and particularly relates to a positioning device for the long pipe joint tube bundle of a boiler header. Background Art

[0002] In the current field of large-capacity boiler manufacturing, as a key component, a large number of long pipe joint tube bundles are widely integrated on the header. After these components are manufactured, they need to be hoisted and transported, and finally delivered to the construction site for precise tube-to-tube docking operations with the membrane wall tube row. Traditionally, a simple fixing method is generally adopted, that is, a flat steel with a thickness of 5 to 6 mm is drilled and simply sleeved on the joint tube bundle for positioning and fixing.

[0003] However, this traditional fixing method has shown significant limitations in practice. For example, during hoisting and transportation, the fixing plate deforms or even falls off, thus unable to ensure the dimensional accuracy and overall shape of the joint tube bundle. When these components are transported to the construction site, the deviation between the actual size and the preset standard has become a problem that cannot be ignored, directly affecting the subsequent installation operations. Specifically, on-site installers have to spend a large amount of extra time and effort on calibration and assembly to make up for the dimensional deviation caused by the fixing failure during transportation. This process not only increases the labor intensity of construction workers but also significantly prolongs the overall installation cycle, which has an adverse impact on the progress control of the project.

[0004] In view of the above background, there is an urgent need for a more efficient and reliable method for fixing the long pipe joint tube bundle of the header to ensure its stability and accuracy during hoisting, transportation, and installation, thereby effectively improving the overall efficiency and quality of boiler manufacturing and installation. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a positioning device for the long pipe joint tube bundle of a boiler header to solve the problems of deformation and falling off of the fixing plate that may occur during hoisting and transportation, and to improve the overall installation efficiency and quality.

[0007] The embodiment of this application provides a positioning device for the long pipe joint tube bundle of a boiler header, including:

[0008] A porous positioning plate, which is used to be sleeved on the pipe ends of the long pipe joint tube bundle of the boiler header and ensure the spacing position between the long pipe joint tube bundles;

[0010] Among them, the vertical plate is fixedly connected to the porous positioning plate.

[0011] In some embodiments, the vertical plate is welded to the porous positioning plate.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0024] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0025] In order to illustrate the technical solutions described in the present application, the following will be described through specific embodiments.

[0026] Please refer to Figures 1 to 3 As shown, the embodiment of the present application provides a positioning device for a long pipe joint tube bundle of a boiler header, including: a U-shaped bolt 3 for fixing, a porous positioning plate 1 for positioning, a vertical plate 2 for supporting, and a nut 4 for pressing.

[0027] Specifically, at the pipe end 6 of the long pipe joint tube bundle of the boiler header, the porous positioning plate 1 is inserted, and the porous positioning plate 1 can ensure the distance position between the long pipe joint tube bundles. For example, a plurality of positioning holes with preset intervals are provided on the porous positioning plate 1, and the positioning holes are sleeved on the pipe end 6.

[0028] The vertical plate 2 and a flat washer 5 are successively inserted on the U-shaped bolt 3, and the nut 4 is sleeved, so as to be assembled into an integral part. Then the integral part is respectively sleeved on the pipe ends 6 of the long pipe joint tube bundles on both sides of the porous positioning plate 1, and the position depths are the same. Then, the nut 4 on the U-shaped bolt 3 is tightened by a wrench for the U-shaped bolt 3 and the vertical plate 2, so as to be fixed on the long pipe joint tube bundle. Finally, the porous positioning plate 1 located on the long pipe joint tube bundle of the boiler header is moved so that the porous positioning plate 1 contacts the vertical plate 2, so that the vertical plate 2 and the porous positioning plate 1 are welded and connected. For example, in the integral part, a fastening hole for clamping and fixing the pipe end 6 is formed between the U-shaped opening of the U-shaped bolt 3 and the vertical plate 2.

[0029] The above-mentioned vertical plate 2 is used to transmit the pressure borne, the nut 4 is used to connect and press the vertical plate 2, and the U-shaped bolt 3 is fixed on the long pipe joint tube bundle, which can prevent the porous positioning plate 1 from deforming and falling off.
