Description

Technical Field

[0001] The utility model relates to a correction device for a tubular steel tower, in particular to a welding mechanical correction device. Background Art

[0002] In the welded tubular steel structure and the bottom chassis Figure 1 The product shown in the figure includes a tubular steel tower and a matching chassis. The chassis is provided with several mounting holes for installation in the circumference. The center of the steel tower and the chassis are provided with a first center hole and a second center hole respectively. The heat generated during the welding process will cause the material to expand, resulting in bulges or deformations in the local area, which will eventually cause the flatness of the chassis to change, affecting the installation and use of subsequent products. This change usually starts in the high-temperature area near the welding point, and the affected area gradually expands with the transfer of heat. Due to the melting and solidification of the welding material, the contraction during the cooling process will also cause uneven deformation, which may cause the chassis surface to be uneven or curved.

[0003] The impact of such deformation on the product includes, but is not limited to: reducing the stability and load-bearing capacity of the structure, affecting the appearance quality, and possibly causing problems in the subsequent assembly process. For example, the unevenness of the chassis may make it difficult to match with other components, or generate additional stress concentration under dynamic loads, thereby affecting the durability and reliability of the entire structure.

[0004] In order to control this effect, appropriate measures need to be taken during the welding process, such as selecting appropriate welding parameters or using appropriate welding techniques, but in most scenarios, appropriate correction work is still required after welding. However, there is currently a lack of products specifically designed for such Figure 1 This is a post-welding mechanical straightening device for steel structural products. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a welding mechanical correction device which can correct a chassis after welding.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a welding machinery correction device, comprising a first positioning mechanism, a second positioning mechanism and a placement platform, the first positioning mechanism can cooperate with the first center hole of the tubular steel tower, and the first positioning mechanism is arranged at one end of the placement platform, the second positioning mechanism can cooperate with the second center hole of the chassis, and the second positioning mechanism is arranged at the other end of the placement platform; the first positioning mechanism and the second positioning mechanism cooperate to form a positioning between the tubular steel tower and the chassis, and the first positioning mechanism and the second positioning mechanism can move towards each other after forming the positioning between the tubular steel tower and the chassis.

[0007] The beneficial effects of the utility model are as follows: after the tubular steel tower and the chassis are placed on the placement platform by means of a gantry crane or the like, the first positioning mechanism and the second positioning mechanism respectively cooperate with the first center hole and the second center hole to abut against the two ends of the tubular steel tower and the chassis to form a positioning therebetween, thereby ensuring that the position between the tubular steel tower and the chassis will not shift during the welding process, thereby preventing welding shift; and after the welding is completed, the first positioning mechanism and the second positioning mechanism move toward each other, that is, the second positioning mechanism applies pressure to the chassis to correct the deformation of the chassis and the tubular steel tower during welding, thereby facilitating the subsequent installation of the finished product.

[0008] Furthermore, the placement platform is provided with a placement groove for placing the tubular steel tower, and the first positioning mechanism includes a first limiting column and a driving source for driving the first limiting column to move. The first limiting column moves toward the tubular steel tower placed on the placement groove driven by the driving source connected thereto until it matches with the first center hole of the tubular steel tower.

[0009] The first limiting column can form a limiting fit with the tubular steel tower by means of expansion tightening with the first center hole, or can form a limiting fit with one end of the tubular steel tower by means of abutting against the end face of the tubular steel tower. After welding is completed, it can still abut against one end of the tubular steel tower to prevent the tubular steel tower from being displaced when the second positioning mechanism applies pressure to the chassis, thereby ensuring the correction effect.

[0010] Furthermore, the second positioning mechanism includes a second limiting column and a correction disk, and the correction disk and the second limiting column are driven to move by the same driving source. The second limiting column moves toward the chassis direction under the drive of the driving source connected to it until it cooperates with the second center hole of the chassis, and the correction disk moves toward the chassis direction under the drive of the driving source connected to it and fits onto the end face of the chassis.

[0011] The second limiting column cooperates with the second center hole to maintain the position of the chassis during welding, thereby improving the welding accuracy, and the second limiting column can be inserted into the first center hole through the second center hole to further ensure that the chassis is located at the center of the tubular steel tower during welding. After the welding is completed, the correction plate moves and gradually fits on the end surface of the chassis to apply pressure to the chassis to ensure the flatness of the chassis after welding, thereby facilitating the installation of subsequent finished products and improving the reliability of the product.

[0012] Furthermore, a plurality of third limiting columns for cooperating with the mounting holes of the chassis are arranged on the circumference of the correction disk; and a detection groove for the detection equipment to pass through and abut against the chassis is also arranged on the correction disk.

[0013] When the chassis is offset after correction welding, the third limit column cooperates with the mounting hole of the chassis so that the correction plate can better fit the end face of the chassis to drive the chassis correction; and the second positioning mechanism is provided with a detection groove which is set through, so that detection equipment such as a micrometer can measure the surface flatness of the chassis through the detection groove before and after the chassis correction, so that the correction effect can be quantified.

[0014] Furthermore, a rotatable rotating rod is provided at the bottom of the placement groove, and the rotating rod is attached to the surface of the tubular steel tower.

[0015] In the above scheme, the first limit column and the second limit column both form a clearance fit with the first center hole and the second center hole. During welding, the rotating rod rotates under the drive of its driving source, and because the rotating rod is attached to the surface of the tubular steel tower, it can drive the tubular steel tower to rotate, and then rotate the unwelded part to an easy-to-process position, thereby improving operational convenience.

[0023] It should be noted that the steel tower used in this embodiment is composed of a tubular steel tower 4 and a chassis 5. The tubular steel tower 4 and the chassis 5 are respectively provided with a first center hole (not shown in the figure) and a second center hole 51 at their centers, and the first center hole and the second center hole 51 have the same outer diameter. The chassis 5 is also provided with a plurality of mounting holes 52 for subsequent mounting in the circumferential direction.

[0024] The utility model embodiment of a welding machine correction device is as follows Figure 1-7As shown: it includes a placement platform 3, and the first positioning mechanism 1 and the second positioning mechanism 2 are respectively provided at both ends of the placement platform 3. A placement groove 31 for placing a tubular steel tower 4 is provided on the placement platform 3. A rotating rod 32 connected to a third driving member 33 and driven to rotate by the third driving member 33 is provided at the bottom of the placement groove 31. When the tubular steel tower 4 is placed in the placement groove 31, the outer circumferential surface of the rotating rod 32 is attached to the outer circumferential surface of the tubular steel tower 4.

[0025] The first positioning mechanism 1 includes a first limiting column 11 and a first driving member 12 connected thereto and driving the first limiting column 11 to move; the second positioning mechanism 2 includes a second limiting column 21 and a correction disk 22, both of which are connected to a second driving member 23 and driven to move by the second driving member 23. It should be explained that the above-mentioned driving members can be various driving sources such as air cylinders, oil cylinders, motors, etc., and the connection between such driving sources and parts and driving them to rotate or move belongs to the prior art, so the connection relationship between each driving source and the parts connected thereto will not be elaborated in detail here. The correction disk 22 includes an inner disk 223 arranged near the center and an outer disk 224 arranged away from the center. Balls 225 are filled between the two to form a rotational connection between the inner disk 223 and the outer disk 224, and the outer disk 224 is clamped on the inner disk 223 to prevent the outer disk 224 from falling. A third limiting column 221 is fixedly provided on the circumference of the outer disk 224 corresponding to the mounting hole 52 of the chassis 5. At the same time, a detection groove 222 is also penetrated on the circumference of the inner disk 223. A detection device (not shown in the figure) can also be fixed on the back of the inner disk 223. The detection device can be a micrometer.

[0026] The following is a brief description of the use of this embodiment: after the tubular steel tower 4 is placed in the placement groove 31 by a gantry crane or other equipment, and the second limiting column 21 is driven by the second driving member 23 to extend first to cooperate with the chassis 5 for positioning and the third limiting column 221 of the correction plate 22 and the mounting hole 52 of the chassis 5, the first limiting column 11, the second limiting column 21 and the correction plate 22 are driven by the first driving member 12 and the second driving member 23 to move from the two ends of the placement groove 31 toward the tubular steel tower 4 respectively, while forming a positioning for the two ends of the tubular steel tower 4. When the chassis 5 is attached to the bottom of the tubular steel tower 4 for processing; after a part of the welding process is welded, the third driving member 33 drives the rotating rod 32 to rotate. Since the outer circumference of the rotating rod 32 is attached to the outer circumference of the tubular steel tower 4 and the second limiting column 21 of the first limiting column 11 and the tubular steel tower 4 and the chassis 5 are all clearance-matched, and the third limiting column 221 realizes the positioning of the chassis 5, when the rotating rod 32 rotates, it can drive the tubular steel tower 4 to rotate, thereby showing the unprocessed part to the operator for welding processing. After the processing is completed, the correction disk 22 continues to press the chassis 5 under the drive of the second driving member 23 so that the chassis 5 can be corrected after being pressed.

[0027] The above embodiment is only one of the preferred specific embodiments of the present invention. Common changes and substitutions made by those skilled in the art within the technical solution of the present invention are all included in the protection scope of the present invention.
