Description

Technical Field

[0001] The present invention relates to the technical field of steel flange correction, and in particular to a tool for fully automatic correction of H-shaped steel flanges for photovoltaic equipment. Background Art

[0002] H-shaped steel flanges are often used to make supporting components for photovoltaic equipment. During the processing of H-shaped steel flanges, the steel flanges are usually welded to both sides of the web first, and then correction work is performed so that the processed steel flanges can meet the installation accuracy requirements of photovoltaic equipment.

[0003] Chinese patent CN112222230A discloses an H-beam flange straightening machine, comprising a straightening machine body, a first roller frame for conveying the H-beam is provided on the front side of the straightening machine body, a second roller frame for conveying the H-beam is provided on the rear side of the straightening machine body, support frames are provided at both ends of the second roller frame, the support frame is provided with a rectangular frame, a crossbeam that can be lifted up and down is provided in the rectangular frame, a rotating plate is rotatably connected to the crossbeam, and an adjustment structure is provided on the crossbeam for driving the rotating plate to move towards the second roller frame, the rotating plate is provided with two fixed blocks parallel to each other, a slot for inserting one end of the H-beam is left between the fixed blocks, a mounting frame is provided in the gap, a circular ring frame of an annular structure is provided on the mounting frame, a driving ring is rotatably connected in the ring frame, and a power component for driving the driving ring to rotate is provided on the mounting frame.

[0004] However, this technical solution has the following defects:

[0005] 1. This solution did not polish the inner and outer sides of the steel flanges before correcting them. This resulted in uneven bumps on the inner and outer surfaces of the steel flanges. These bumps would cause the steel flanges to bend and deform during the correction process, affecting the correction accuracy.

[0006] 2. This solution cannot be applied to the grinding and correction of steel flanges of various thicknesses, and its application range is limited;

[0007] 3. During the correction process, this solution can only correct the steel flanges on the upper or lower side of the web, and cannot simultaneously correct the steel flanges on the upper and lower sides of the web. This results in uneven force on the steel flanges during the correction process, affecting the correction effect.

[0008] 4. When the H-shaped steel flange used in photovoltaic equipment is used to make and install support components, due to its poor calibration accuracy, the final support component assembly accuracy is poor, causing great safety hazards during the use of photovoltaic equipment and reducing its service life. Summary of the Invention

[0009] The purpose of the present invention is to address the shortcomings of the existing technology and provide a fully automatic correction tool for H-shaped steel flanges for photovoltaic equipment. By grinding the steel flange before correction and then performing the correction work, interference caused by the protrusions on the surface of the steel flange can be avoided during correction, and the correction accuracy is high. By setting a grinding wheel with adjustable span, it can be suitable for grinding the inside and outside of steel flanges of different thicknesses.

[0145] The correction units 3 are provided with two groups for supporting the web of the steel flange.

[0146] Among them, a reciprocating plate 326 is slidably inserted into the guide groove 3221;

[0147] The upper portion of the reciprocating plate 326 is connected to a pressing shaft 325 that contacts the side of the cam 323;

[0152] A sleeve plate for fixing the position of the rack 328 is provided on the outside of the rack 328 , and two groups of racks 328 are provided.

[0153] It should be noted that when working, Figure 1-2 As shown, the steel flange of the H-beam after welding is placed on the upper part of the pushing roller 1011 and the web is placed on the upper part of the inner support 102. The driving motor in the pushing roller 1011 is started. The driving motor drives the H-beam flange through the pushing roller 1011 to pass through the flattening unit 2 and the straightening unit 3 in sequence to complete the flattening and straightening work.

[0154] Specifically, when the H-shaped steel passes through the grinding unit 2 and the correction unit 3, the driving motor at the lower part of the driving wheel 1031 is started, and the driving motor drives the transmission wheel 1032 to rotate through the driving wheel 1031, and the transmission wheel 1032 drives the rack 328 to swing through the main gear 1033, and the rack 328 drives the cam 323 to rotate through the second driven gear 324. Figure 5-6 As shown, the cam 323 presses the shaft 325 to drive the reciprocating plate 326 to compress the return spring 327 and move. The reciprocating plate 326 drives the outer pressure roller 3291 to press the outer side of the steel flange through the outer correction shaft 329, so that the outer side of the steel flange is corrected.

[0155] like Figure 3-4 、 Figure 7As shown, while the rack 328 drives the second driven gear 324 to rotate, the second driven gear 324 drives the linkage shaft 311 to rotate through the first driven gear 310. The linkage shaft 311 drives the inner correction blocks 313 on both sides to move and compress the second preload spring 3132 through the second convex roller 312. The inner correction block 313 pushes the first pressure roller 3131 to the inner side of the steel flange, so that the inner side of the steel flange is squeezed outward by the first pressure roller 3131 and the outer side of the steel flange is squeezed inward by the outer pressure roller 3291, thereby achieving the effect of all-round automatic correction of the steel flange.

[0156] In the present invention, when the outer straightening shaft 329 drives the outer pressure roller 3291 to move toward the outer steel flange, the outer straightening shaft 329 also drives the second sleeve 221 to move through the connecting rod 2211, and the second sleeve 221 drives the outer grinding wheel 222 to move to contact the outer side surface of the steel flange. At the same time as the linkage shaft 311 drives the second convex roller 312 to rotate, the linkage shaft 311 also drives the first convex roller 212 to rotate through the first transmission chain 2121, and the first convex roller 212 drives the reciprocating seats 214 on both sides to move along the limit plate 213 and The first preload spring 215 is compressed, and the reciprocating seat 214 drives the inner grinding wheel 216 to move from the inside of the first sleeve 211 to contact the inner side of the steel flange, and the inner grinding wheel 216 drives the first clutch wheel 217 to move to engage with the second clutch wheel 218. The adjusting button 232 is turned, and the adjusting button 232 synchronously drives the fifth clutch wheel 237 and the fourth clutch wheel 235 to rotate through the bearing block 233, so that the fourth clutch wheel 235 engages with the third clutch wheel 224 and the fourth clutch wheel 235 engages with the second clutch wheel 218. Figure 9 As shown, the driving mechanism 234 is started, and the driving mechanism 234 drives the second clutch wheel 218 to rotate through the fourth clutch wheel 235. The second clutch wheel 218 drives the inner grinding wheel 216 to rotate through the first clutch wheel 217, so that the inner side of the steel flange is ground flat. At the same time, the fourth clutch wheel 235 drives the fifth clutch wheel 237 to rotate through the second transmission chain 236. The fifth clutch wheel 237 drives the rotating shaft 223 to rotate through the third clutch wheel 224. The rotating shaft 223 drives the outer grinding wheel 222 to rotate, so that the outer side of the steel flange is ground flat. In this way, the steel flange before correction is polished and then the correction work is carried out, avoiding interference caused by protrusions on the surface of the steel flange during correction, and achieving a high correction accuracy.

[0157] For steel flanges of different thicknesses, such as Figure 6-7 、 Figure 11As shown, the present invention rotates the adjusting screw 2112 before the steel flange is ground. The adjusting screw 2112 drives the slider 2111 to move along the guide rail 2110 through the threaded engagement between the adjusting screw 2112 and the first sleeve 211. The slider 2111 drives the second clutch wheel 218 to move to a position where the second clutch wheel 218 and the first clutch wheel 217 can just contact when the inner grinding wheel 216 extends out of the first sleeve 211 and contacts the inner side of the steel flange. When grinding and correcting steel flanges of different thicknesses, the swing angle of the first convex roller 212 and the second convex roller 312 is controlled by controlling the rotation angle of the driving wheel 1031. The moving angles are different, and thus the feeding distances of the inner grinding wheel 216 and the outer grinding wheel 222 for grinding the inner and outer sides of the steel flange, and the first pressure roller 3131 and the outer pressure roller 3291 for correcting the inner and outer sides of the steel flange are different. The present invention can control the rotation angle of the adjusting button 232 to realize the engagement of the fifth clutch wheel 237 with the third clutch wheel 224 and the engagement of the fourth clutch wheel 235 with the second clutch wheel 218 under different feeding distance conditions, thereby achieving the effect of grinding the inner and outer sides of steel flanges of different thicknesses by setting the grinding wheel with adjustable span, and has a wide range of applications.

[0159] like Figure 5 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0160] The present invention provides two groups of correction units 3 with respect to the web of the steel flange, and also symmetrically provides two groups of grinding units 2 with respect to the web of the steel flange. When the upper part of the steel flange is corrected, the driving wheel 1031 drives the correction units 3 and the grinding units 2 on the upper and lower parts of the steel flange to work synchronously through the transmission wheel 1032, which not only improves the correction work efficiency, but also balances the influence of uneven force on one side of the steel flange when the upper part of the steel flange is corrected, thereby further improving the correction accuracy.

[0161] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
