Description

Technical Field

[0001] This utility model relates to the field of steel chimneys, and in particular to a tooling for assisting in the processing of steel chimney cylindrical structures. Background Technology

[0002] Currently, the most common connection method for steel chimney structures is flange bolt connection. The cylindrical structure includes the cylindrical body, the flange welded and fixed to the bottom of the cylindrical body, and the flange stiffening plate welded to the flange and the cylindrical body. The two cylindrical structures are connected by flange bolts to realize the assembly of the steel chimney.

[0003] The current production process for most chimney manufacturers is as follows: after the flange is cut, it is welded together on the ground to form a shape; the weld is ground; the flange is leveled with a rolling machine; the flange is spot-welded to the outside of the cylinder (the width from the edge of the cylinder to the edge of the flange is measured with a ruler to control the flatness and verticality); the upper and lower flange sections are hoisted onto the roller frame and connected, and then bolted; the stiffening plates are fully welded and fixed; the fillet weld between the flange and the outside of the cylinder is fully welded; the bolts are removed, and the fillet weld between the flange and the inside of the cylinder is fully welded; the process is complete.

[0004] However, this process makes it difficult to control the installation accuracy of the cylinder, flange, and flange stiffeners, resulting in defective products. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling for assisting in the processing of steel chimney cylinder structures. Its advantages are that it assists in the processing of the cylinder structure, improves the installation accuracy of the cylinder, flange, and flange stiffener, and increases the yield rate.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0007] A tooling for assisting in the processing of steel chimney structures, characterized in that it includes a tooling platform.

[0008] A leveling assembly is provided, with the flange placed on a tooling platform. Several leveling assemblies are arranged in a ring and positioned on the tooling platform outside the flange. The leveling assembly is used to level the flange.

[0009] Several assembly marks marking the assembly positions of the flange stiffeners are provided on the tooling platform between two adjacent leveling components.

[0010] Support plates, several of which are arranged in a ring and fixedly installed on a tooling platform inside the flange, the cylinder is suspended inside the flange and placed on several support plates.

[0011] Through the above technical solutions, the tooling platform surface has excellent flatness, providing a stable and accurate reference surface for assembly operations; the leveling component is used to level the flange, ensuring the flatness of the flange assembly; the assembly mark is used to mark the installation position of the flange stiffener; the support plate is used to increase the setting height of the cylinder, meeting the assembly requirements of the cylinder and the flange; through the auxiliary processing of the tooling, the installation accuracy of the cylinder, flange, and flange stiffener is improved, increasing the yield rate; it also greatly improves work efficiency and reduces the workload of on-site installation.

[0012] In one embodiment of the present invention, the leveling assembly includes a screw fixedly mounted on a tooling platform, a pad mounted on the screw, a leveling plate sleeved on the screw, and a locking nut threadedly connected to the screw.

[0013] The locking nut is tightened onto the screw to press the calibration plate against the flange.

[0014] The above technical solution uses a locking nut to press the flange onto the alignment plate, thereby fixing the flange and preventing it from shifting or deforming during assembly. Combined with the critical welding process, this ensures the flatness of the assembled flange.

[0015] In one embodiment of this utility model, the thickness of the gasket is equal to the thickness of the flange.

[0016] Through the above technical solution, the pad is used to limit the downward pressure height of the leveling plate, wherein the thickness of the pad is equal to the thickness of the flange, so that the leveling plate will not cause deformation of the flange while leveling the flange.

[0017] In one embodiment of the present invention, the pad includes a shim nut and a washer.

[0018] The above technical solution improves the stability of the pad by connecting the shim nut to the screw thread. The gasket is used to compensate for and adjust the height difference between the shim nut and the flange.

[0019] In one embodiment of this utility model, the support plate is recessed into the outer edge of the cylinder.

[0020] With the above technical solution, the support plate is recessed into the outer edge of the cylinder, that is, the support plate does not protrude beyond the circumferential surface of the cylinder; thus avoiding interference between the support plate and the flange when the flange is assembled on the cylinder.

[0021] In one embodiment of the present invention, several positioning arc grooves of different shapes are provided on the upper surface of several of the support plates;

[0022] Several positioning arc grooves of different shapes are combined to form an annular groove for positioning the cylinder.

[0023] Through the above technical solution, an annular groove formed by combining several positioning arc grooves is used to position the cylinder.

[0024] As described above, the tooling of this utility model for assisting in the processing of steel chimney structures has the following beneficial effects:

[0025] The tooling platform has excellent flatness, providing a stable and accurate reference surface for assembly operations. The leveling assembly is used to level the flange. By tightening the lock nut, the leveling plate presses the flange down, thus fixing the flange and preventing it from shifting or deforming during assembly. Combined with key welding processes, this ensures the flatness of the flange assembly. Assembly marks are used to mark the installation position of the flange stiffeners. The support plate increases the installation height of the cylinder to meet the assembly requirements of the cylinder and flange. Through the auxiliary processing of the tooling, the installation accuracy of the cylinder, flange, and flange stiffeners is improved, increasing the yield rate. It also greatly improves work efficiency and reduces the workload of on-site installation. Attached Figure Description

[0035] Example 1

[0036] Please see Figures 1 to 4 This utility model provides a tooling for assisting in the processing of steel chimney structure, including a tooling platform 4. The surface of the tooling platform 4 has excellent flatness, providing a stable and accurate reference surface for assembly operations.

[0037] The leveling assembly 5 and the flange 1 are placed on the tooling platform 4. Several leveling assemblies 5 are arranged in a ring and set on the tooling platform 4 outside the flange 1. The leveling assembly 5 is used to level the flange 1 and ensure the flatness of the flange 1 assembly.

[0038] The leveling assembly 5 includes a screw 51 welded and fixed to the tooling platform 4, and a pad 52, a leveling plate 53, and a locking nut 54 arranged sequentially from bottom to top on the screw 51. The leveling plate 53 is sleeved on the screw 51, and the locking nut 54 is threaded to the screw 51. By tightening the locking nut 54, the leveling plate 53 presses against the flange 1, thereby fixing the flange 1 to prevent the flange 1 from shifting or deforming during the assembly process. Combined with the key welding process, this ensures the flatness of the assembled flange 1.

[0039] The shim 52 is used to limit the downward pressure height of the leveling plate 53. The thickness of the shim 52 is equal to the thickness of the flange 1, so that the leveling plate 53 will not cause deformation of the flange 1 while leveling it. In this embodiment, the shim 52 includes a shim nut 521 and a washer 522. The shim nut 521 is threadedly connected to the screw 51, thereby improving the stability of the shim 52. The washer 522 is used to compensate for the height difference between the shim nut 521 and the flange 1, so that the thickness of the shim 52, which is composed of the shim nut 521 and the washer 522, is equal to the thickness of the flange 1.

[0040] Please see Figure 2 Several assembly marks 11 are provided on the tooling platform 4 between two adjacent leveling components 5; the assembly marks 11 are used to mark the installation position of the flange stiffener 3 and improve the assembly accuracy of the flange stiffener 3.

[0041] Please see Figures 1 to 4 Several support plates 12 are arranged in a ring and fixedly installed on the tooling platform 4 inside the flange 1. The cylinder 2 is suspended inside the flange 1 and placed on the support plates 12. The support plates 12 are used to increase the installation height of the cylinder 2 to meet the assembly requirements of the cylinder 2 and the flange 1. Generally, the thickness of the support plate 12 is half the thickness of the flange 1. The support plate 12 is recessed into the outer edge of the cylinder 2, that is, the support plate 12 does not protrude beyond the circumferential surface of the cylinder 2, thereby avoiding interference between the support plate 12 and the flange 1 when the flange 1 is assembled on the cylinder 2. The upper end face of the several support plates 12 is provided with positioning arc grooves of different shapes. Several positioning arc grooves of different shapes are combined to form an annular groove. The annular groove is used to position the cylinder 2 on the tooling platform 4 and improve the assembly accuracy of the cylinder 2 and the flange 1.

[0042] Example 2

[0043] Please see Figure 5 and Figure 6 Taking the production process of a set of cylindrical structures as an example, a set of cylindrical structures includes an upper cylindrical structure 15 and a lower cylindrical structure 19; its assembly and welding process is as follows:

[0044] (1) The production process of the upper cylindrical structure 15 is as follows: the upper flange 16 is placed on the tooling platform 4, avoiding the installation position of the upper flange stiffener 18, and a ring of screws 51 is welded on the tooling platform 4 along the circumference of the upper flange 16. A pad 52, a leveling plate 53 and a locking nut 54 are installed on each screw 51; the leveling plate 53 is adjusted and the locking nut 54 is tightened so that the leveling plate 53 is pressed on the upper flange 16, and then several assembly marks 11 are engraved on the tooling platform 4 between two adjacent leveling components 5; then a ring of support plate is welded on the tooling platform 4 of the inner ring of the upper flange 16. 12; The upper cylinder 17 is hoisted inside the upper flange 16 and placed on several support plates 12; the initial assembly of the upper cylinder 17 and the upper flange 16 is completed, and then the outer sides of the upper flange 16 and the upper cylinder 17 are segmented welded (segmented welding is used for temporary fixation, which facilitates the subsequent tightening and fitting of the upper and lower flange bolts). Then, according to the assembly mark 11, the upper flange stiffening plate 18 is segmented welded to the upper flange 16 and the upper cylinder 17 (segmented welding is used for temporary fixation, which reduces welding deformation); then the upper cylinder 17, the upper flange 16 and the upper flange stiffening plate 18 that are initially welded together are hoisted out of the tooling platform 4 for use.

[0045] (2) The production process of the lower cylinder structure 19 is as follows: the lower flange 20 is placed on the tooling platform 4 and fixed by the straightening plate 53. Then the lower cylinder 21 is hoisted into the lower flange 20 and placed on several support plates 12 to complete the preliminary assembly of the lower cylinder 21 and the lower flange 20. Then the lower flange 20 and the lower cylinder 21 are segmented welded on the outside. It is worth noting that the lower flange stiffener 22 is not welded in this step. Then the lower cylinder 21 and the lower flange 20 that are initially welded together are hoisted out of the tooling platform 4 for use.

[0046] (3) Assembly and welding of the upper cylindrical structure 15 and the lower cylindrical structure 19: Hoist the upper cylindrical structure 15 and the lower cylindrical structure 19 onto the roller frame 23. Assemble the upper flange 16 and the lower flange 20 according to the orientation diagram, and tighten the upper flange 16 and the lower flange 20 with flange bolts 24. Flatten the gap between the upper flange 16 and the lower flange 20. Weld the lower flange stiffening plate 22 onto the lower flange 20 and the lower cylindrical body 21 (weld the lower flange stiffening plate 22 according to the principle of one-to-one correspondence between the upper flange stiffening plate 18 and the lower flange stiffening plate 22). First, constrain the already fitted flange faces; then, fully weld the outer corner welds of the upper flange 16 and upper cylinder 17, and the lower flange 20 and lower cylinder 21; fully weld the upper flange stiffener 18 with the upper flange 16 and upper cylinder 17, and the lower flange stiffener 22 with the lower flange 20 and lower cylinder 21; then remove the flange bolts 24, and finally fully weld the inner corner welds of the upper flange 16 with the upper cylinder 17, and the lower flange 20 with the lower cylinder 21 (to reduce errors caused by welding deformation). At this point, the assembly of cylinder 2, flange 1, and flange stiffener 3 is complete.

[0047] In summary, this utility model improves the installation accuracy of the cylinder 2, flange 1, and flange stiffener 3, ensures the flatness and perpendicularity of the flange 1 assembly, and also greatly improves work efficiency and reduces the workload of on-site installation.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
