Description

Technical Field

[0001] The present application relates to RTO equipment, and in particular to a deformation correction structure of RTO equipment. Background Art

[0002] During the RTO cabinet manufacturing process, deformation is common due to the numerous reinforcing ribs on the cabinet, which can easily deform after welding. Furthermore, deformation is common during the manufacturing process, as the equipment must be hoisted to another area for subsequent processing. Correction of large cabinets is difficult, and currently relies primarily on manual force, which is time-consuming and labor-intensive.

[0003] For the correction of the box, there are some process measures that can be adopted before welding the box, such as selecting suitable welding materials, adjusting welding parameters, and determining the welding sequence. These parameters can control the deformation of part of the box. However, the deformation caused by frequent lifting after welding is completed is difficult to correct by manpower.

[0004] The RTO equipment consists of three boxes connected by a U-shaped air duct to absorb thermal deformation. After hoisting, due to the different centers of gravity of the three boxes, the top of the box joints exhibit greater deformation than the bottom, resulting in a difference of approximately 7 to 8 mm in the top and bottom dimensions. Summary of the Invention

[0005] The purpose of the present invention is to provide a deformation correction structure for RTO equipment. In view of the deformation of the lower box of the RTO, a box adjustment rod is designed to correct the deformation, and the effect is obvious.

[0006] To achieve the above objectives, the present invention provides the following technical solutions.

[0007] An embodiment of the present application discloses a deformation correction structure for RTO equipment, comprising three boxes arranged side by side, wherein the bottom of each box is formed with a plurality of H-shaped steels arranged in an array for support, and an adjustable distance rod is supported between two adjacent H-shaped steels between two adjacent boxes. The adjustable distance rod comprises a first screw, a sleeve, and a second screw connected in sequence by threads, wherein the opposite sides of the first screw and the second screw are respectively supported on the two H-shaped steels, and the sleeves are connected to the first screw and the second screw in opposite directions of threads.

[0008] Preferably, in the above-mentioned RTO equipment deformation correction structure, a hexagonal bayonet is formed on the outside of the sleeve.

[0009] Preferably, in the above-mentioned RTO equipment deformation correction structure, the first screw and the second screw adopt M42 coarse thread.

[0010] Preferably, in the above-mentioned RTO equipment deformation correction structure, a separation space is formed between the first screw and the second screw inside the sleeve.

[0011] Preferably, in the above-mentioned RTO equipment deformation correction structure, support steel plates are respectively welded to the opposite sides of the first screw and the second screw.

[0012] Preferably, in the above-mentioned RTO equipment deformation correction structure, two adjacent boxes are connected by a U-shaped air duct.

[0013] Compared with the existing technology, the advantage of this technical solution is that in order to correct the deformation of the box, an adjustment distance rod is designed. The adjustment rod is placed on the reinforced H-shaped steel at the lower end of the box. When the lower distance of the box is expanded, the deformation of the upper part will also be reduced, and finally the upper and lower sizes will be the same. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the drawings described below are only some embodiments recorded in this application. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0018] The following is a detailed description of the technical solutions in the embodiments of the present invention, with reference to the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Combine Figure 1-3As shown, the RTO equipment deformation correction structure includes three boxes 100 arranged side by side. The bottom of each box 100 is formed with multiple H-beams 200 arranged in an array for support. An adjustable distance rod 300 is supported between two adjacent H-beams 200 between two adjacent boxes 100. The adjustable distance rod 300 includes a first screw 301, a sleeve 302, and a second screw 303, which are connected in sequence through threads. The first and second screws 301, 303 are supported on the two H-beams 200 on opposite sides. The sleeve 302 is connected to the first and second screws 301, 303 in opposite directions. A hexagonal bayonet 304 is formed on the outside of the sleeve 302. The first and second screws 301, 303 use M42 coarse threads. A space 305 is formed between the first and second screws 301, 303 within the sleeve 302. A support steel plate 306 is welded to the opposite sides of the first screw rod 301 and the second screw rod 303. Two adjacent boxes 100 are connected by a U-shaped air duct 400.

[0020] In this embodiment, the adjustable distance rod consists of two left and right screws and a sleeve in the middle. The left and right screws adopt M42 coarse thread, and steel plates are welded at both ends to support the force. The left screw is made into a positive thread, and the right screw is made into a negative thread. The middle sleeve is also processed into positive and negative internal threads corresponding to the screws. In this way, by rotating the middle sleeve, the screws on both sides can be extended or shortened at the same time, and a hexagonal bayonet for easy adjustment is welded on the middle sleeve to facilitate operation.

[0021] During the RTO design process, the bottom supporting H-beam 200 and the housing 100 were bolted together with oblong bolt holes. Because the equipment expands at high temperatures, the housing cannot be directly welded to the H-beam. This leaves room for adjustment of the distance bar. When the distance bar is adjusted, the three housings 100 will move, but the range of movement is limited to the oblong bolt holes, and the bottom H-beam is connected to the foundation, keeping it fixed.

[0022] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0023] The above is only a specific implementation method of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
