Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pipeline welding, and relates to a boiler pipeline welding calibration device. BACKGROUND

[0002] A boiler is an energy conversion device, which is used for heating water or other fluids to a certain parameter by using heat energy released by fuel combustion or other heat energy. In the production of boiler pipelines, welding equipment is needed to weld multiple groups of boiler pipelines in order to ensure the length of the boiler pipeline. A calibration device is needed for positioning during the welding of the boiler pipeline.

[0003] At present, during the welding of a boiler pipeline, it is necessary to ensure the neat butt joint of the pipeline connection during the welding process of the boiler pipeline, and to ensure the stability during the welding of the pipeline and the sealing of the welding point after the welding. However, in the connection of the boiler pipeline, in order to facilitate the welding between the pipelines, the ends of the pipelines to be connected are usually aligned and spliced. During the alignment and splicing process, it is difficult for workers to calibrate, which reduces the efficiency of welding. Meanwhile, the ground environment is uneven, which is not convenient for raising the pipeline. If a direct raising method is used, the calibration and alignment of the port splicing cannot be quickly realized. After the welding is completed, the welding mark is usually judged by observation or touch. However, it is not conducive to judging the thickness difference of the welding mark by observation or touch, so as to be not conducive to the calibration, analysis and detection of the metal pipe fitting.

[0040] With reference to Figures 1 to 7 The boiler pipeline welding calibration device provided by the present application comprises a workbench 2, an auxiliary detection mechanism 11, two auxiliary calibration mechanisms 14 and an auxiliary linkage mechanism 16.

The upper end surface of the upper top block 1109 is fixedly provided with a connecting spring 10. The track plate 1107 is provided with a track groove 1106. The side surface of the track plate 1107 is fixedly connected with the outer wall of the sliding seat 5. The two mounting blocks 1104 are fixedly connected with the outer wall of the fixed seat 12.

[0042] The auxiliary calibration mechanism 14 comprises a base 1401, an auxiliary barrel 1402, a rotating ring 1403, a linkage ring 1404, six first mounting plates 1405, three fixed rods 1406, six second mounting plates 1407, three third mounting plates 1408, three screw rods 1409, three outer rods 14010 and three inner blocks 14011. The base 1401 is fixedly arranged on the upper end surface of the workbench 2. The rotating ring 1403 is threadedly sleeved on the outer wall of the auxiliary barrel 1402. The rotating ring 1403 is rotatably sleeved in the linkage ring 1404. The linkage ring 1404 is movably sleeved on the outer side of the auxiliary barrel 1402.

[0043] The auxiliary linkage mechanism 16 comprises a rotating disc 1601, a fixed disc 1602, four bottom plates 1604, four extrusion plates 1605, a plurality of rotating shafts 1606, a plurality of movable rods 1607, four outer plates 1608 and an electric telescopic rod 1609. The rotating disc 1601 is rotatably embedded in the top seat 1.

[0044] Specifically, in the embodiment, the outer wall of the top seat 1 is provided with an outer shell 17. The outer shell 17 is embedded with a servo motor 18. The output end of the servo motor 18 is fixedly connected with the rotating disc 1601. The side surface of the top seat 1 is provided with a connecting hole 15.

[0045] That is, when the servo motor 18 is started, the rotating disc 1601 is driven to rotate. The fixed disc 1602 is fixedly arranged on the side surface of the rotating disc 1601. Four slide grooves 1603 are equidistantly and circumferentially arranged on the side of the fixed disc 1602 away from the rotating disc 1601. The bottom plate 1604 is fixedly arranged on the lower end of the extrusion plate 1605. One end of the bottom plate 1604 is slidably embedded in the slide groove 1603. The other end of the bottom plate 1604 is connected with one end of the movable rod 1607 through the rotating shaft 1606. The other end of the movable rod 1607 is rotatably connected with the outer plate 1608. The outer plate 1608 is fixedly arranged on one end of the electric telescopic rod 1609. The other end of the electric telescopic rod 1609 is fixedly arranged at the center position of the side surface of the fixed disc 1602.

[0046] It can be seen that the end of the pipe to be welded is located in the connecting hole 15 and passes through the auxiliary linkage mechanism 16. When auxiliary rotary driving of the pipe is required, the outer plate 1608 on the outside is moved by using the telescopic effect of the electric telescopic rod 1609. The outer plate 1608 moves the movable rod 1607 connected to the outer plate 1608 through the rotating shaft 1606. Since the other end of the movable rod 1607 is connected to the bottom plate 1604 and the bottom plate 1604 is slidingly embedded in the sliding groove 1603, the outer plate 1608 in motion will pull the movable rod 1607 to change the inclination angle, thereby pulling the bottom plate 1604 to slide in the sliding groove 1603, and changing the position of the extrusion plate 1605, thereby achieving expansion and contraction movement. When the expansion movement is in the expansion movement, the distance to the inner wall of the pipe is continuously reduced until the extrusion plate 1605 is extruded on the inner wall of the pipe. Finally, the fixed disc 1602 and the extrusion plate 1605 are driven to rotate by the servo motor 18.

[0047] Specifically, in the embodiment, one end of the threaded rod 4 is fixed with a rotating handle after penetrating through the outer wall of the workbench 2, the sliding seat 5 is in the shape of a Chinese character and two bent ends are respectively threadedly sleeved with the threaded rod 4 and slidingly sleeved with the guide rod, and the two sides of the lower end surface of the workbench 2 are both fixedly provided with the supporting legs 3. That is, in the use process, the sliding seat 5 is driven to move laterally by rotating the threaded rod 4, thereby realizing the linkage displacement of the fixing seat 12. At the same time, since the outer wall of the sliding seat 5 is provided with the groove 7, the connecting spring 10 is embedded in the groove 7, the side surface of the upper block 1109 is provided with the sliding block, the connecting spring 10 is located on the sliding block, and the sliding block is slidingly embedded in the groove 7, that is, the auxiliary detection mechanism 11 is synchronously driven to move laterally.

[0048] Since the end of the driving rod 11012 is rotatably arranged in the track plate 1107, the pushing block 1108 is threadedly sleeved on the driving rod 11012 and slidingly embedded in the track groove 1106, the rotating drum 11010 is connected to the mounting block 1104 through the connecting block 11011, both ends of the rotating drum 11010 are sleeved with the disc 1103, the lower end of the first linkage plate 1101 is connected with the disc 1103, the upper end of the first linkage plate 1101 is provided with the first roller shaft 1102, the upper end of the second linkage plate 1105 is connected with the disc 1103, the lower end of the second linkage plate 1105 is provided with the second roller shaft 1102, and the outer side of the roller shaft 1102 is wrapped with the cloth with pigment.

[0049] When the pipe to be welded is completed, the auxiliary detection mechanism 11 is moved to the outside of the welding point according to the position of the welding point, at which time the rotating drive rod 11012 drives the push block 1108 to displace, and the push block 1108 continuously generates extrusion thrust on the upper block 1109 during displacement. The upper block 1109 is continuously extruded against the connecting spring 10 and the roller shaft 1102 at the lower end of the second linkage plate 1105 on both sides during displacement, at which time the second linkage plate 1105 connected to the upper end of the disc 1103 is rotated outside the rotating cylinder 11010 under the extrusion force, and the first linkage plate 1101 at the upper end is connected to the disc 1103 to rotate synchronously. At this time, the first linkage plate 1101 continuously moves towards the outer wall of the pipe, realizing the contact between the roller shaft 1102 with pigment on the cloth installed at the upper end and the position of the pipe welding point. At this time, according to the effect of the pipe rotating drive by the servo motor 18, the roller shaft 1102 with pigment on the cloth continuously draws a circular path on the outside of the welding point, and finally the welding quality is quickly detected, analyzed and processed according to the circular path drawn on the outside.

[0050] Specifically, in the embodiment, the adjusting rod 902 is a bidirectional screw rod and is rotatably arranged in the auxiliary support 8. The end of the adjusting rod 902 is fixed with a rotating block after penetrating out of the auxiliary support 8. Two auxiliary push blocks 904 are threadedly sleeved on the adjusting rod 902. The anti-skid piece 901 is arranged on the auxiliary supporting plate 903, which is rotatably embedded in the auxiliary support 8. The lower end of the auxiliary supporting plate 903 is in an inclined section structure. When the pipe penetrates through the auxiliary support 8, the adjusting rod 902 is rotated, and the two auxiliary push blocks 904 are displaced to the sides. The auxiliary push blocks 904 continuously push and extrude the auxiliary supporting plate 903 at the lower end to rotate and move upwards during displacement. The anti-skid piece 901 at the upper end rotates and moves upwards with it. When the anti-skid piece 901 is attached to the lower end of the pipe to be welded, the auxiliary supporting effect is realized, the stability during welding is improved, and the auxiliary supporting adjustment is performed after the auxiliary calibration mechanism 14 completes the auxiliary calibration clamping work.

[0051] Specifically, in the embodiment, the auxiliary barrel 1402 is fixedly arranged on the upper end surface of the base 1401, the first mounting plate 1405 is arranged outside the linkage ring 1404, one end of the fixed rod 1406 is rotatably arranged in the first mounting plate 1405 through the first rotating rod, the other end of the fixed rod 1406 is rotatably arranged in the third mounting plate 1408 through the second rotating rod, the second mounting plate 1407 is arranged on the outer wall of the auxiliary barrel 1402, the third mounting plate 1408 is rotatably arranged in the second mounting plate 1407 through the third rotating rod, the outer rod 14010 is fixedly arranged on the outer wall of the third mounting plate 1408, the inner block 14011 is vertically and slidingly arranged in the outer rod 14010, and the screw rod 1409 is threadedly connected to the upper end of the outer rod 14010 and rotatably connected to the inner block 14011.

[0052] In use, after the pipe to be welded passes through the auxiliary barrel 1402, part of the pipe body is located in the auxiliary barrel 1402, at this time, the rotating ring 1403 on the outer side is rotated to displace on the barrel body of the auxiliary barrel 1402, and the rotating ring 1403 displaces while the linkage ring 1404 displaces, the linkage ring 1404 constantly pushes the fixed rod 1406 to move in the displacement process, the fixed rod 1406 generates a pushing force on the third mounting plate 1408 in the movement process, so that the third mounting plate 1408 rotates on the inner side of the second mounting plate 1407, the third mounting plate 1408 drives the outer rod 14010 to rotate in the rotation process, and then drives the inner block 14011 to rotate, the inner block 14011 generates a central extrusion effect on the axial core position of the auxiliary barrel 1402 in the turning process, so that the positioning, calibration, extrusion and clamping effect of the pipe to be welded with the axial core of the auxiliary barrel 1402 as the center point is completed.

[0053] At the same time, the upper end of the inner block 14011 is rotatably connected to the screw rod 1409, and the inner block 14011 is vertically and slidingly arranged in the outer rod 14010, at this time, the position height of the screw rod 1409 in the outer rod 14010 is changed by rotating the screw rod 1409, so that the extension length of the inner block 14011 is changed, and the size of the clamping distance is changed, and because the lower end of the inner block 14011 is semicircular, the inner block 14011 can better adapt to the cylindrical pipe structure outer wall for clamping effect.

[0054] The specific use process of the present application is as follows:

[0055] When the device is used, one end of one pipe to be welded is installed in the top base 1, and the other pipe is connected with the other end of the pipe in port surface contact through the auxiliary base 8 and one of the auxiliary calibration mechanisms 14, and then the auxiliary calibration mechanism 14 is rotated to rotate the outer rotating ring 1403 to achieve the auxiliary calibration support effect, so that the two pipes are adjusted to the same horizontal height to achieve the auxiliary clamping support effect, then the auxiliary support mechanism 9 in the auxiliary base 8 is adjusted to achieve the auxiliary support effect on one end of one pipe, and the auxiliary linkage mechanism 16 is driven to achieve the positioning and extrusion support effect on the other end of the other pipe, so that the port alignment and splicing and auxiliary support effect of the two pipes are achieved; at this time, the pipes that have completed splicing and alignment can be welded, and after welding is completed, the welded pipe can be rotated by the servo motor 18, and the auxiliary detection mechanism 11 is clamped on the outer wall of the pipe welding point before the servo motor 18 is started, and the welded pipe rotates during the driving process of the servo motor 18, and the auxiliary detection mechanism 11 detects the circumferential path outside the welding point and draws a line during detection, so that the quality of welding can be quickly detected according to the depth of the line drawing path.
