AI Technical Summary
During the production of large cylinders, when the pipes of the six DN200 pipe openings are welded, the stress generated will cause the opening of the shell to collapse, which will cause the flange to turn outward and affect the welding quality.
A pipe port support tool is designed, including 8 connection pipes that protrude outward from the central connection pipes. The angle between adjacent connection pipes is 45°. Each connection pipe is connected to a sleeve at one end facing away from the central connection plate. The top plate and a jack are arranged on the inside of the shell. The end of the jack is supported on the top plate, and the telescopic end is inserted into the sleeve to support the opening of the shell and reduce the impact of welding.
By using pipe port support tooling, the impact on the shell when the pipe port pipe is welded to the shell can be effectively reduced, the opening collapse and flange turn outwards can be prevented, and the welding quality can be improved.

Abstract
Description
Technical Field
[0001] The present application relates to the production of a large cylinder, and in particular to a pipe mouth supporting tool. Background Art
[0002] There are 6 DN200 pipe openings at one end of the shell. When the pipe connection of the pipe opening is welded to the shell, the stress generated by welding will cause the shell opening to collapse slightly, thereby causing the flange close to this side of the shell to be pulled and turned outward. In the past, there were generally fewer openings on equipment, most of which were 3. When 6 pipe openings are set, the impact is even greater. Utility Model Content
[0003] The utility model aims to provide a pipe mouth supporting tool, which can reduce the influence of welding the pipe mouth connecting pipe.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.
[0005] An embodiment of the present application discloses a pipe orifice supporting tooling for supporting the inner wall of one end of a shell, wherein 6 pipe orifices are arranged symmetrically on the left and right sides of the shell, wherein the pipe orifice on each side includes 1 horizontal one and 1 each at an angle of 45° up and down, including a central connecting plate and 8 connecting pipes protruding outward from the central connecting plate, wherein the angle between two adjacent connecting pipes is 45°, and each end of the connecting pipes facing away from the central connecting plate is connected with a sleeve along its extension direction, and the shell is provided with a top plate on the inner side of each pipe orifice, each top plate corresponds to one of the sleeves, and a jack is arranged between the top plate and the corresponding sleeve, wherein the end of the jack is supported on the top plate, and the telescopic end of the jack is inserted into and abutted against the inside of the sleeve.
[0006] Preferably, in the above-mentioned pipe mouth supporting tooling, the connecting pipe is welded to the central connecting plate.
[0007] Preferably, in the above-mentioned pipe mouth supporting tooling, the connecting pipe and the sleeve are connected by bolts.
[0008] Preferably, in the above-mentioned pipe opening supporting tool, the sleeve includes a support plate and a sleeve opening formed on the support plate.
[0009] Preferably, in the above-mentioned pipe mouth supporting tooling, the outer end of the sleeve in the vertical direction is also provided with the jack and is supported on the shell by padding the top plate.
[0010] Compared with the prior art, the utility model has the advantages that when the six pipe ports and the shell are positioned and installed for preparation for welding, a supporting tool is installed, and the tool is an eight-tube support frame with a support pipe at 45 degrees, and a mechanical jack is used to support the opening. The size of the mechanical jack is adjusted according to the distance between the support frame and the opening of the pipe port on the shell to support the shell opening, so as to reduce the impact on the shell when the pipe port and the shell are welded. The two unused support frames are also equipped with mechanical jacks to support the inside of the shell so that the force is evenly distributed. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in the present application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.
[0012] Figure 1 Shown is a schematic diagram of the pipe mouth supporting tooling in an embodiment of the utility model. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] Combination Figure 1As shown, the pipe nozzle supporting tool 100 is used to support the inner wall of one end of the shell 200. There are 6 pipe nozzles 201, which are symmetrically arranged on the left and right sides of the shell 200. Each side of the pipe nozzle 201 includes one horizontal one and one each at an angle of 45° up and down, including a central connecting plate 101 and 8 pipes 102 protruding outward from the central connecting plate 101. The angle between two adjacent pipes 102 is 45°. The end of each pipe 102 away from the central connecting plate 101 is connected with a sleeve 103 along its extension direction. The shell 200 is provided with a top plate 104 on the inner side of each pipe nozzle 201, each top plate 104 corresponds to one of the sleeves 103, and a jack 105 is arranged between the top plate 104 and the corresponding sleeve 103. The end of the jack 105 is supported on the top plate 104, and the telescopic end of the jack 105 is inserted into and abutted against the inside of the sleeve 103. The pipe 102 is welded to the central connecting plate 101. The pipe 102 is connected to the sleeve 103 by bolts. The sleeve 103 includes a support plate 106 and a sleeve 107 formed on the support plate 106. The outer end of the sleeve 103 in the vertical direction is also provided with a jack 105 and supported on the housing 200 by a cushioned top plate 104.
[0015] When in use, when the six pipe ports and the shell are positioned and installed for preparation for welding, the supporting tooling is installed. The tooling is an eight-tube support frame with a support pipe at 45°, and a mechanical jack is used to support the opening. The size of the mechanical jack is adjusted according to the distance between the support frame and the opening of the pipe port on the shell to support the shell opening to reduce the impact on the shell when the pipe port and the shell are welded. The two unused support frames should also be equipped with mechanical jacks to support the inside of the shell so that the force is evenly distributed. After the tooling is used, the eversion of the equipment flange caused by welding is measured, and there is no change.
[0016] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
