Description

Technical Field

[0001] The invention belongs to the technical field of pipeline welding and relates to a boiler pipeline welding calibration device. Background Art

[0002] A boiler is an energy conversion device that uses the heat energy released by fuel combustion or other heat energy to heat the working medium water or other fluids to certain parameters. When producing boiler pipes, in order to ensure the length of the boiler pipes, welding equipment is needed to weld multiple groups of boiler pipes. When welding the boiler pipes, a calibration device is needed for positioning.

[0003] At present, when welding boiler pipes, it is necessary to ensure the neat docking of the pipe joints during the welding process, as well as the stability of the welded pipes and the sealing of the welding points after welding. However, when connecting boiler pipes, in order to facilitate welding between pipes, it is usually necessary to align and splice the ends of the pipes to be connected. During the alignment and splicing process, it is difficult for workers to calibrate, which reduces the efficiency of welding. At the same time, the external ground environment is uneven, which makes it inconvenient to raise the pipes. If a direct raising method is used, the calibration and alignment of the port splicing cannot be quickly achieved. At the same time, after welding is completed, it is often necessary to judge the welding marks by observation or touch, but observation or touch is not conducive to judging the thickness difference of the welding marks, and is therefore not conducive to calibration, analysis and detection of metal pipe fittings.

An auxiliary support 8 is arranged on the upper end surface of the workbench 2, a through hole 19 is arranged in the middle of the auxiliary support 8, and an auxiliary support mechanism 9 is embedded on the bottom end surface of the inner wall of the through hole 19. The auxiliary support mechanism 9 includes two anti-slip sheets 901, an adjusting rod 902, two auxiliary support plates 903 and two auxiliary push blocks 904. Two sliding grooves 6 are arranged on the upper end surface of the workbench 2, a threaded rod 4 is rotatably arranged in one sliding groove 6, a guide rod is arranged in the other sliding groove 6, one end of the sliding seat 5 is slidably embedded in one sliding groove 6, and the other end of the sliding seat 5 is slidably embedded in the other sliding groove 6.

A top seat 1 is arranged on the upper end surface of the workbench 2.

[0041] The auxiliary detection mechanism 11 includes two No. 1 linkage plates 1101, four rollers 1102, four discs 1103, two mounting blocks 1104, two No. 2 linkage plates 1105, a track plate 1107, a pushing block 1108, an upper top block 1109, two rotating drums 11010, two connecting blocks 11011 and a driving rod 11012. A connecting spring 10 is fixedly arranged on the upper end surface of the upper top block 1109, a track groove 1106 is opened on the track plate 1107, and the side surface of the track plate 1107 is fixedly connected to the outer wall of the sliding seat 5. The two mounting blocks 1104 are both fixedly connected to the outer wall of the fixed seat 12.

[0042] The auxiliary calibration mechanism 14 includes a base 1401, an auxiliary cylinder 1402, a swivel 1403, a linkage ring 1404, six No. 1 mounting plates 1405, three fixed rods 1406, six No. 2 mounting plates 1407, three No. 3 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 swivel 1403 is threadedly sleeved on the outer wall of the auxiliary cylinder 1402, the swivel 1403 is rotatably sleeved inside the linkage ring 1404, and the linkage ring 1404 is movably sleeved on the outer side of the auxiliary cylinder 1402.

[0043] The auxiliary linkage mechanism 16 includes a turntable 1601 , a fixed plate 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 turntable 1601 is rotatably embedded in the top seat 1 .

[0044] Specifically, in this embodiment, a shell 17 is provided on the outer wall of the top seat 1 , a servo motor 18 is embedded in the shell 17 , an output end of the servo motor 18 is fixedly connected to the turntable 1601 , and a connecting hole 15 is provided on the side of the top seat 1 .

[0045] That is, when the servo motor 18 is started, it drives the turntable 1601 to rotate, and the fixed plate 1602 is fixedly arranged on the side of the turntable 1601. Four slide grooves 1603 are opened at equal intervals along the circumferential direction on the side of the fixed plate 1602 away from the turntable 1601. The bottom plate 1604 is fixedly arranged at the lower end of the extrusion plate 1605, and 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 to one end of the movable rod 1607 through the rotating shaft 1606. The other end of the movable rod 1607 is axially connected to the outer plate 1608. The outer plate 1608 is fixed to one end of the electric telescopic rod 1609, and the other end of the electric telescopic rod 1609 is fixed at the center position of the side of the fixed plate 1602.

[0046] It can be seen that the end of the pipe to be welded is located within the connection hole 15 and passes through the auxiliary linkage mechanism 16. When auxiliary rotational drive of the pipe is required, the telescopic effect of the electric telescopic rod 1609 is utilized to drive the outer plate 1608 on the outside to move accordingly. During the movement of the outer plate 1608, the movable rod 1607 connected to the outside through the rotating shaft 1606 will be driven to move. Since the other end of the movable rod 1607 is connected to the bottom plate 1604 and the bottom plate 1604 is slidably embedded within the chute 1603, that is, the moving outer plate 1608 at this time will pull the movable rod 1607 to change the inclination angle, and further pull the bottom plate 1604 to perform a sliding displacement within the chute 1603. At the same time, since the bottom plate 1604 is fixed to the lower end of the pressing plate 1605, when the bottom plate 1604 performs a sliding displacement, it will drive the pressing plate 1605 to perform a synchronous sliding displacement, thereby changing the position of the pressing plate 1605 to achieve expansion and contraction movements; when in the expansion movement, the distance from the inner wall of the pipe will be continuously reduced until it is pressed against the inner wall of the pipe. Finally, during the process of the servo motor 18 driving the turntable 1601, the fixed disk 1602 and the pressing plate 1605 are driven to rotate the pipe.

[0047] Specifically, in this embodiment, one end of the threaded rod 4 passes through the outer wall of the workbench 2 and is fixed with a turning handle. The sliding seat 5 is in a U-shaped configuration, and the two bent ends are respectively threadedly sleeved on the threaded rod 4 and slidably sleeved on the guide rod. Legs 3 are fixedly arranged on both sides of the lower end surface of the workbench 2; that is, during use, by rotating the threaded rod 4, the sliding seat 5 is driven to undergo a lateral displacement, thereby realizing the linkage displacement of the fixed seat 12. At the same time, since a groove 7 is formed on the outer wall of the sliding seat 5, the connecting spring 10 is embedded within the groove 7. A slider is provided on the side surface of the upper top block 1109, and the connecting spring 10 is located on the slider. The slider is slidably embedded within the groove 7, that is, the auxiliary detection mechanism 11 will accordingly perform a synchronous lateral displacement operation.

[0048] Since the end of the driving rod 11012 is rotatably arranged within the track plate 1107, the pushing block 1108 is threadedly sleeved on the driving rod 11012, and the pushing block 1108 is slidably embedded within the track groove 1106. The rotating cylinder 11010 is connected to the mounting block 1104 through the connecting block 11011. Disks 1103 are sleeved on both ends of the rotating cylinder 11010. The lower end of the first linkage plate 1101 is connected to the disk 1103, and the first roller 1102 is arranged at the upper end of the first linkage plate 1101. The upper end of the second linkage plate 1105 is connected to the disk 1103, and the second roller 1102 is arranged at the lower end of the second linkage plate 1105. A cloth roll with pigment is wrapped around the outside of the roller 1102.

[0049] When the welding work of the pipe to be welded is completed, the auxiliary detection mechanism 11 is moved to the outer side of the welding point according to the position of the welding point. At this time, the rotation of the driving rod 11012 is restricted to drive the pushing block 1108 to move. The pushing block 1108 continuously generates an extrusion thrust on the upper top block 1109 during the displacement process. The upper top block 1109 moves upward during the force-bearing process and continuously squeezes the connecting spring 10 and the roller 1102 at the lower end of the No. 2 linkage plate 1105 on both sides. At this time, the No. 2 linkage plate 1105 subjected to the extrusion force drives the disc 110 connected at the upper end. The outer side of the rotating drum 11010 rotates, and the No. 1 linkage plate 1101 at the upper end is connected with the disc 1103 to make them rotate synchronously. At this time, the No. 1 linkage plate 1101 continuously moves toward the outer wall of the pipeline, so that the roller 1102 of the cloth with paint installed at the upper end is in contact with the position of the pipeline welding point. At this time, according to the effect of the servo motor 18 driving the pipeline to rotate, the roller 1102 of the cloth with paint continuously draws a circular path outside the welding point, and finally the welding quality is quickly detected and analyzed according to the outer circular line drawing path.

[0050] Specifically, in this embodiment, the adjusting rod 902 is a bidirectional screw and is rotatably arranged in the auxiliary support 8. After the end of the adjusting rod 902 passes through the auxiliary support 8, a rotating block is fixed thereon. Two auxiliary push blocks 904 are threadedly sleeved on the adjusting rod 902. The anti-slip sheet 901 is arranged on the auxiliary support plate 903. The auxiliary support plate 903 is rotatably embedded in the auxiliary support 8. The lower end of the auxiliary support plate 903 has an inclined cross-sectional structure. When the pipeline passes through the auxiliary support 8, the adjusting rod 902 is rotated, and the two auxiliary push blocks 904 are displaced to both sides. During the displacement process, the auxiliary push blocks 904 continuously push and squeeze the auxiliary support plate 903 with an inclined cross-section at the lower end to make it rotate and move upward. The anti-slip sheet 901 at its upper end moves upward with the rotation. When the anti-slip sheet 901 is attached to the lower end of the outer wall of the pipeline to be welded, an auxiliary support effect is achieved, thereby improving the stability during the welding process. The auxiliary support adjustment is performed after the auxiliary calibration mechanism 14 completes the auxiliary calibration clamping work.

[0051] Specifically, in the present embodiment, the auxiliary through cylinder 1402 is fixedly arranged on the upper end surface of the base 1401, the No. 1 mounting plate 1405 is arranged on the outer side of the linkage ring 1404, one end of the fixed rod 1406 is rotatably arranged in the No. 1 mounting plate 1405 through the No. 1 rotating rod, and the other end of the fixed rod 1406 is rotatably arranged in the No. 3 mounting plate 1408 through the No. 2 rotating rod, the No. 2 mounting plate 1407 is arranged on the outer wall of the auxiliary through cylinder 1402, the No. 3 mounting plate 1408 is rotatably arranged in the No. 2 mounting plate 1407 through the No. 3 rotating rod, the outer rod 14010 is fixedly arranged on the outer wall of the No. 3 mounting plate 1408, the inner block 14011 is vertically slidably embedded in the outer rod 14010, the screw 1409 is threadedly sleeved on the upper end of the outer rod 14010, and the screw 1409 is rotatably sleeved with the inner block 14011.

[0052] When in use, after the welding pipe passes through the auxiliary cylinder 1402, part of the pipe body is located in the auxiliary cylinder 1402. At this time, the outer swivel 1403 is rotated to make it displace on the body of the auxiliary cylinder 1402. When the swivel 1403 is displaced, the linkage ring 1404 is displaced as well. The linkage ring 1404 will continuously push the fixed rod 1406 to move during the displacement. The fixed rod 1406 generates thrust on the No. 3 mounting plate 1408 during the movement, causing it to rotate on the inner side of the No. 2 mounting plate 1407. During the rotation, the No. 3 mounting plate 1408 drives the outer rod 14010 to rotate, thereby driving the inner block 14011 to rotate. During the flipping process, the inner block 14011 generates a central extrusion effect toward the axis core position of the auxiliary cylinder 1402, thereby completing the positioning, calibration, extrusion and clamping effect of the welding pipe with the axis core of the auxiliary cylinder 1402 as the center point.

[0053] At the same time, the upper end of the inner block 14011 is rotatably sleeved with the screw 1409 and the inner block 14011 is vertically slid and embedded in the outer rod 14010. At this time, by rotating the screw 1409, the height of its position in the outer rod 14010 is changed, thereby changing the protruding length of the inner block 14011, thereby changing the size of the clamping distance; and because the lower end of the inner block 14011 is semi-arc-shaped, it can better adapt to the outer wall of the cylindrical pipe structure to achieve a fitting clamping effect.

[0054] The specific use process of the present invention is:

[0055] When the device is used, after one end of one of the pipes to be welded is installed in the top seat 1, the other pipe is passed through the auxiliary support 8 and one of the auxiliary calibration mechanisms 14 to make port surface contact connection with the pipe at the other end. Since the two pipes to be welded pass through the two auxiliary calibration mechanisms 14 respectively, the auxiliary calibration mechanism 14 is rotated, that is, the outer swivel 1403 is rotated to make it produce auxiliary calibration support effect, and the two pipes are adjusted to be at the same horizontal height for auxiliary clamping support effect, and then the auxiliary support mechanism 9 located in the auxiliary support 8 is adjusted to provide auxiliary support effect to one end of one of the pipes, and the auxiliary coupling is driven. The driving mechanism 16 performs positioning, squeezing and supporting effect on one end of the other pipe, at which time the ports of the two pipes are aligned, spliced ​​and auxiliary supporting effect is achieved; at this time, the pipes that have been spliced ​​and aligned can be welded, and after welding, the servo motor 18 can be used to drive the welded pipe to rotate, and before the servo motor 18 is started, the auxiliary detection mechanism 11 is used to clamp the outer wall of the pipe welding point.
