[0022] In the following description, many specific details are set forth in order to fully understand the present utility model, but the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0024] Embodiment

[0025] Refer to Figures 1-4, which is the first embodiment of the present utility model. This embodiment provides a perpendicularity detection device for welding flange steel pipes, including a detection base 1, a fixing mechanism 2, and a perpendicularity detection mechanism 3. The fixing mechanism 2 is fixedly installed at the top of the detection base 1, and the perpendicularity detection mechanism 3 is fixedly installed on the right side of the fixing mechanism 2. The perpendicularity detection mechanism 3 includes a bracket 301, an installation groove 302, a threaded rotating rod 303, a moving slider 304, a telescopic spring 305, a connecting block 306, a first U-shaped frame 307, a measuring wheel 308, a second U-shaped frame 309, and a guiding wheel 3010. The bracket 301 is fixedly installed on the right side of the top of the detection base 1. The installation groove 302 is opened in the inner cavity of the bracket 301. The threaded rotating rod 303 is fixedly installed in the inner cavity of the installation groove 302. The moving slider 304 is fixedly installed on the outer surface of the threaded rotating rod 303. The telescopic spring 305 is fixedly installed in the inner cavity of the moving slider 304. The connecting block 306 is fixedly connected to the left end of the telescopic spring 305. The first U-shaped frame 307 is fixedly connected to the left side of the connecting block 306. The measuring wheel 308 is movably installed on the outer surface of the first U-shaped frame 307. The second U-shaped frame 309 is fixedly installed at the bottom on the left side of the bracket 301. The guiding wheel 3010 is movably installed on the outer surface of the second U-shaped frame 309.

[0026] Specifically, the outer wall of the first U-shaped frame 307 is rotatably connected to the inner wall at the center of the measuring wheel 308. A pen holder 5 is fixedly installed on the back at the center of the measuring wheel 308. A touch pen 6 is movably installed in the inner cavity of the pen holder 5. A digital tablet 7 is fixedly installed on the back of the touch pen 6.

[0027] Furthermore, during the perpendicularity measurement, the touch pen 6 moves synchronously with the measuring wheel 308, and the tip of the touch pen 6 can draw the trajectory of the outer surface of the measuring wheel 308 rolling on the outer surface of the steel pipe on the digital tablet 7.

[0028] Specifically, a first installation hole 8 is opened at the top of the moving slider 304. A second installation hole 9 is opened on the right side of the first installation hole 8. A limiting rod 10 is fixedly installed in the inner cavity of the second installation hole 9. The limiting rod 10 is slidably connected to the second installation hole 9.

[0029] Furthermore, the moving slider 304 can move up and down on the outer surface of the limiting rod 10 through the second installation hole 9, which can enhance the stability of the moving slider 304 moving on the threaded rotating rod 303, and thus improve the perpendicularity measurement accuracy.

[0030] Specifically, a plug rod 4 is fixedly installed at the bottom of the bracket 301. A motor 11 is fixedly installed at the top of the threaded rotating rod 303.

[0031] Furthermore, when the motor 11 is started, the output end of the motor 11 can drive the threaded rotating rod 303 to rotate, and thus can drive the moving slider 304 and the measuring wheel 308 to move up and down on the outer surface of the steel pipe.

[0032] Specifically, a controller 12 is fixedly installed on the right side of the top of the support 301. A display screen 13 is arranged on the front surface of the controller 12, and the digitizing tablet 7 is electrically connected to the controller 12.

[0033] Furthermore, by electrically connecting the digitizing tablet 7 to the controller 12, the drawn movement trajectory can be converted into perpendicularity data and displayed on the display screen 13 of the controller 12, achieving the effect of visually observing the perpendicularity of the steel pipe after surveying and being able to record the perpendicularity information of the steel pipe, solving the problems that the perpendicularity of the steel pipe cannot be recorded after detection and the perpendicularity of the steel pipe cannot be visually seen.

[0034] Specifically, the fixing mechanism 2 includes a support base 201, a sliding rod 202, a sliding base 203, a support spring 204 and an arc-shaped clamping plate 205. The support base 201 is fixedly installed on the left side of the top of the detection base 1, and the sliding rod 202 is fixedly installed in the middle part of the two support bases 201.

[0035] Furthermore, through the setting of the fixing mechanism 2, the arc-shaped clamping plate 205 clamps the outer wall of the steel pipe, so that the steel pipe can be fixed, improving the stability of the steel pipe during the processing and facilitating welding and perpendicularity measurement of it.

[0036] Specifically, the sliding base 203 is fixedly installed on the outer surface of the sliding rod 202. The support spring 204 is fixedly installed on the side of the sliding base 203 close to the center of the detection base 1, and the arc-shaped clamping plate 205 is fixedly connected to the side of the support spring 204 close to the center of the sliding base 203.

[0037] Furthermore, through the sliding base 203, the steel pipe clamped at the top can be moved, so that the outer surface of the steel pipe is closely attached to the outer surfaces of the guide wheel 3010 and the measuring wheel 308.

[0038] During use, first place the welded flange steel pipe in the middle part between the two arc-shaped clamping plates 205. The support spring 204 presses the arc-shaped clamping plate 205 to fix the steel pipe. Move the sliding base 203 at the bottom to make the outer surface of the steel pipe closely attached to the outer surfaces of the guide wheel 3010 and the measuring wheel 308. Start the motor 11. The motor 11 drives the threaded rotating rod 303 to rotate. The threaded rotating rod 303 drives the moving slider 304 to move on the surfaces of the threaded rotating rod 303 and the limiting rod 10. The moving slider 304 drives the touch pen 6 to move on the digitizing tablet 7, so that one end of the touch pen 6 draws a movement path on the digitizing tablet 7. The digitizing tablet 7 transmits the movement path to the controller 12. The controller 12 displays the perpendicularity data of the welded flange steel pipe through the display screen 13. During the welding process, it is necessary to regularly detect and record the data to ensure that the perpendicularity of the steel pipe meets the requirements. After welding is completed, view the perpendicularity data of the steel pipe through the display screen 13 and perform further processing as needed.

[0039] In summary, by using the measuring wheel 308 and the guiding wheel 3010 in cooperation, the perpendicularity of the steel pipe can be detected, eliminating the need for manual visual measurement of the perpendicularity effect, improving the accuracy of perpendicularity measurement, ensuring the correct installation positions of the flange and the steel pipe, which helps to guarantee the connection quality of the pipeline and the normal operation of the system, and prevent problems such as leakage, insufficient pressure or excessive deformation caused by incorrect installation.
