Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a tooling frame for integral heat treatment of a screen-type superheater. Background Art

[0002] For boiler products involving T91 material platen superheater tube panels, the welds welded to T91 and the elbows of T91 itself must be heat treated as required. Considering that the size of the tube panel is generally: length ≥4 meters, width ≥2 meters, and the number of tube panels in a single boiler is relatively large, generally ≥40 panels. Before entering the heating furnace for heat treatment, the tube panel will be deformed during transportation between workshops, loading into the furnace and heat treatment.

[0003] The transportation and loading of the tube panels of the platen superheater are time-consuming and laborious, and the tube panels will deform greatly during heat treatment. If multiple heating furnaces are used to heat treat the tube panels, it will cause a certain degree of waste of natural gas, and ultimately the heat treatment quality of the tube panels cannot be guaranteed, and the production time is extended. Utility Model Content

[0005] In order to achieve the above-mentioned object, the utility model is implemented by the following technical solutions: a tooling frame for integral heat treatment of a platen superheater, comprising a base, and also comprising a plurality of support assemblies arranged in sequence and at intervals in the transverse direction;

[0006] The support assembly includes two columns and multiple tubes. The two columns are arranged longitudinally and fixedly installed on both sides of the base respectively. A accommodating space is formed between the two columns and the base. The multiple tubes are arranged in sequence along the longitudinal direction and have their two ends fixedly connected to the corresponding two columns respectively. The multiple tubes divide the accommodating space into multiple limited spaces.

[0007] Furthermore, two ends of the pipe are spot welded to the corresponding two columns respectively.

[0008] Furthermore, the plurality of tubes are arranged in a transverse direction.

[0009] Furthermore, the limiting space is adapted to the tube panel.

[0010] Furthermore, the four connecting rods of the base are welded end to end in sequence, the base is a rectangular frame structure, and the connecting rods are made of two channel steels that are arranged opposite to each other and welded.

[0011] Furthermore, a lifting lug is fixedly installed on the top of the column.

[0012] The beneficial effects of the utility model are as follows: the utility model provides a tooling frame for overall heat treatment of a screen-type superheater, which facilitates the overall transportation and furnace loading of multiple tube screens, reduces the deformation of the tube screens after heat treatment, and reduces the number of heating furnaces used for heat treatment by using multiple screens in the same furnace, saves the use of natural gas, improves product quality, and shortens manufacturing time.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In this application, unless otherwise clearly specified and limited, the terms "connection" and "fixation" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0020] In the description of the present application, it should be understood that the terms "longitudinal", "transverse", "horizontal", "top", "bottom", "up", "down", "inside" and "outside" etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the description of the present utility model, the meaning of "plurality" is more than two, unless otherwise clearly and specifically limited.

[0022] like Figure 1-Figure 4 As shown, the utility model provides a tooling frame for integral heat treatment of a platen-type superheater, comprising a base and a plurality of support components which are arranged in sequence and at equal intervals in the transverse direction.

[0023] The support assembly includes two columns and multiple pipes. The two columns are arranged longitudinally and welded to the two sides of the base respectively, and a receiving space is formed between the two columns and the base. Multiple pipes are arranged longitudinally at equal intervals and welded to the corresponding two columns at both ends, and the multiple pipes divide the receiving space into multiple limited spaces.

[0024] Four of these tooling racks can be placed in each heating furnace.

[0025] When the tooling rack is in use, the assembled tube panels of the platen superheater are stacked layer by layer in the limited space. The tube panels of different heights can be separated by the pipes. About 12 to 13 panels can be stacked in each tooling rack.

[0026] In one embodiment, two ends of the pipe are spot welded to two corresponding columns to improve the strength of the pipe.

[0027] In one embodiment, the plurality of tubes are arranged in a transverse direction.

[0028] In one embodiment, the limiting space is adapted to the tube panel, and limits the tube panel to prevent it from shaking up and down, thereby improving stability.

[0029] In one embodiment, the four connecting rods of the base are welded end to end in sequence, the base is a rectangular frame structure, and the connecting rods are made of two channel steels that are arranged opposite to each other and welded.

[0030] Preferably, the column itself is also a channel steel.

[0031] The base and the columns of the tooling frame are made of channel steel, and the pipes are selected from stock pipes. These raw materials are very easy to obtain and have low costs, which further reduces the cost and manufacturing difficulty of the tooling frame.

[0032] In one embodiment, a lifting lug is fixedly installed on the top of the column to facilitate the overall lifting of the tooling frame.

[0033] The base and columns of this tooling frame are made of channel steel. The pipes are selected from the inventory. The assembled tube panels of the screen-type superheater are stacked layer by layer in the limited space. The tube panels of different heights are separated by pipes. About 12 to 13 panels are stacked in each tooling frame. The top of the column is welded with lifting lugs to facilitate overall lifting and transportation. The use of this tooling frame can well stack the assembled tube panels into modules, which is convenient for lifting, transportation and furnace loading. It also reduces deformation during heat treatment and reduces the number of heating furnaces used for heat treatment, shortens the product manufacturing cycle, and ensures product quality.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
