Description

Technical Field

[0001] The utility model belongs to the technical field related to ammonia synthesis towers, and particularly relates to a welding and transportation tooling for the outer frame of an ammonia synthesis tower. Background Technique

[0002] An ammonia synthesis tower is a key device in ammonia synthesis production. The design and manufacturing precision of the catalyst frame inside it have a crucial impact on the efficiency and stability of the entire ammonia synthesis process. Since the size of the ammonia synthesis tower is usually large and the operating conditions are strictly required, the production and installation of the catalyst frame require extremely high precision control. The inner and outer catalyst frames of the ammonia synthesis tower can be assisted in manufacturing by using a wire winding device with resistance welding technology. However, since the structural form of the filter cartridge processed by the wire winding device is that the surface wire is circumferential on the outside, and the two structural forms do not match, after wire winding, the processed filter cartridge needs to be cut open and flattened, and then rolled into a circle and the support wire is welded together to complete the manufacturing of the inner and outer catalyst frames. During the manufacturing process, the tolerances such as roundness and straightness of the catalyst frame need to be maintained within a very strict range to ensure the efficient synthesis of ammonia and hydrogen under the action of the catalyst. To achieve such precision requirements, manufacturers usually adopt advanced manufacturing processes and strict quality control measures, but it still has the following drawbacks in actual use:

[0003] After the production of each plate of the outer catalyst frame is completed, it needs to be welded into a finished product before it can be transported to the installation equipment for installation. Due to the large size of the ammonia synthesis tower and relatively harsh operating conditions, problems such as excessive gaps and ring ribs tipping may still occur during the production of the outer catalyst frame. These problems may cause damage to the catalyst frame and increase production costs. Content of the Utility Model

[0004] The purpose of the utility model is to provide a welding and transportation tooling for the outer frame of an ammonia synthesis tower, which solves the problem that deviations are easily generated during the welding and transportation of the outer catalyst frame of the ammonia synthesis tower by setting a tooling main body.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model provides a welding and transportation tooling for the outer frame of an ammonia synthesis tower, including a tooling main body. The tooling main body includes three tooling components combined with each other in a circular array. The tooling component includes an arc plate, a fastening plate, and fastening bolts. A plurality of the arc plates are parallel to each other. At the same short side of the tops of all the arc plates, a fastening plate is fixed. The part of the fastening plate extending out of the top of the arc plate is inserted with fastening bolts in a rectangular array. The tooling main body provides internal support for the outer catalyst frame to be welded through three mutually combined tooling components.

[0007] Further, the tooling assembly further includes jack holes. The jack holes are arranged in a rectangular array at the edge of the top of the arc plate away from the fastening plate. The jack holes correspond to the positions of the fastening bolts, so that the fastening bolts are inserted into the jack holes on the arc plate.

[0008] Further, the end parts of the arc plates included in two adjacent tooling assemblies are in contact with each other. The fastening plate on the arc plate included in one tooling assembly is arranged on the top of the arc plate included in the adjacent tooling assembly. The fastening bolt inserted into the fastening plate on the top of one arc plate is inserted into the jack hole on the adjacent arc plate and extends out of the bottom of the arc plate. When working, when the fastening nut is screwed onto it, the two adjacent revolution components are combined together.

[0009] Further, the tooling assembly further includes columns. Two vertical columns are fixedly penetrated and fixed together in the multiple arc plates included in the same tooling assembly. The arc plates included in the same tooling assembly are supported together by the columns.

[0010] The utility model has the following beneficial effects:

[0011] By setting the tooling main body, the utility model solves the problem that the external catalyst frame is prone to deviation during the group welding and transportation processes. After the tooling main body is assembled, the processed external catalyst frames are placed one by one on the outside of the tooling main body, and then group welding is carried out immediately. After group welding, the complete external catalyst frame is arranged on the surface of the tooling main body. After being packaged as a whole, it is transported to the installation position. When working, the complete external catalyst frame can maintain its shape well during transportation. When it is necessary to disassemble the tooling main body in the complete external catalyst frame, directly unscrew the fastening nut on the fastening bolt, and then the tooling main body in the complete external catalyst frame can be divided into three tooling assemblies and taken out from the external catalyst frame to complete the work. This enables the external catalyst frame to be well supported by the tooling during the group welding and transportation processes, reduces the deformation of the processed external catalyst frame, and reduces the change in dimensional accuracy during the group welding and transportation processes of the external catalyst frame.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0019] Please refer to Figures 1 - 3 , the present invention also provides a welding and transportation tooling for the outer frame of an ammonia synthesis tower, including a tooling main body 1. The tooling main body 1 includes three tooling components 101 combined in an annular array with each other. The tooling component 101 includes an arc plate 1011, a fastening plate 1014 and a fastening bolt 1015. A plurality of arc plates 1011 are parallel to each other. Fastening plates 1014 are fixed at the same short side at the top of all arc plates 1011. The part of the fastening plate 1014 extending out of the top of the arc plate 1011 is inserted with fastening bolts 1015 in a rectangular array. During operation, the outer catalyst frame is restricted by the tooling main body 1, so that the position and size of the outer catalyst frame can be well determined during welding. One tooling main body 1 is combined by three tooling components 101. During operation, the ends of the arc plates 1011 with the same height included in two tooling components 101 are abutted against each other, so that the fastening plate 1014 on one arc plate 1011 covers the top of the other arc plate 1011. Then, the fastening bolts 1015 are inserted into the fastening plate 1014 and into the jacks 1013 on the arc plate 1011, so that two adjacent tooling components 101 are initially combined together.

[0020] Specifically, the tooling component 101 further includes jacks 1013. Jacks 1013 are arranged in a rectangular array at the edge of the top of the arc plate 1011 far from the fastening plate 1014. The positions of the jacks 1013 correspond to those of the fastening bolts 1015. The arc plate 1011 provides the function of combining with the fastening bolts 1015 on the fastening plate 1014 through the jacks 1013.

[0021] Furthermore, the ends of the arc plates 1011 included in two adjacent tooling components 101 are abutted against each other. The fastening plate 1014 on the arc plate 1011 included in one tooling component 101 is arranged on the top of the arc plate 1011 included in the adjacent tooling component 101. The fastening bolt 1015 inserted into the fastening plate 1014 on the top of one arc plate 1011 is inserted into the jack 1013 on the adjacent arc plate 1011 and extends out of the bottom of the arc plate 1011. When working, after the fastening bolt 1015 extends out of the bottom of the arc plate 1011, the fastening nut is rotated to the bottom of the fastening bolt 1015 and rotated to be pressed against the bottom of the arc plate 1011, so that when working, the two adjacent tooling components 101 are combined together.

[0022] Furthermore, the tooling component 101 further includes columns 1012. Two vertical columns 1012 are fixedly penetrated through the multiple arc plates 1011 included in the same tooling component 101, and the multiple arc plates 1011 included in the same tooling component 101 are connected together through the columns 1012.

[0023] The operation process of this embodiment is as follows: When working, the ends of the arc plates 1011 with the same height included in the two tooling components 101 are abutted against each other, so that the fastening plate 1014 on one arc plate 1011 covers the top of the other arc plate 1011. Then, the fastening bolt 1015 is inserted into the fastening plate 1014 and into the jack 1013 on the arc plate 1011, so that the two adjacent tooling components 101 are preliminarily combined together. Then, the external fastening nut is rotated to the bottom of the fastening bolt 1015 and rotated to be pressed against the bottom of the arc plate 1011, so that when working, the two adjacent tooling components 101 are combined together. After completion, it is combined into a complete tooling main body 1, and then the external catalyst frame can be assembled and welded. The processed external catalyst frames are placed on the outside of the tooling main body 1 one by one, and then assembled and welded. After assembly and welding, the complete external catalyst frame is arranged on the surface of the tooling main body 1. After being integrally packaged, it is transported to the installation position, so that when working, the complete external catalyst frame can maintain its shape well during transportation. When it is necessary to disassemble the tooling main body 1 in the complete external catalyst frame, the fastening nut on the fastening bolt 1015 is directly unscrewed, and then the tooling main body 1 in the complete external catalyst frame can be divided into three tooling components 101 and taken out from the external catalyst frame to complete the work.
