Further, the crater catcher and welder 17 may be slidably disposed on the outside of the elbow weldment by a linear displacement rail 9. Wherein, linear displacement track 9 can set up in multi-direction adjustment platform 1 both sides and top, and the crater catcher slides and sets up in the linear displacement track 9 that is located the top, and welding machine 17 slides through semicircle support 10 and sets up in the linear displacement track 9 that is located both sides, semicircle support 10 and crater catcher electric connection, and semicircle support 10 through with the signal transmission of crater catcher remove to the crater 2 department of waiting to weld.
As shown in fig. 2, the semicircular brackets 10 are disposed at two sides of the bent pipe weldment, the welding machine 17 is disposed on one of the semicircular brackets 10, the semicircular brackets 10 at two sides can move in opposite directions to splice to form a whole circular bracket 11, which encloses the welded junction 2 of the bent pipe weldment, and the welding machine 17 performs circular motion on the whole circular bracket 11 to weld the welded junction 2.
In the present apparatus, the linear displacement rail 9 may be a vertical rail extending along the length direction of the integral elbow weldment or a curved rail extending along the curved track of the integral elbow weldment. The welding machine 17 is arranged on the semicircular bracket 10, the semicircular bracket 10 is arranged in the linear displacement rail 9, namely, the contact between the welding machine 17 and the welded junction 2 is used by splicing the semicircular bracket 10 into a complete annular rail in a way of opposite movement.
The welder 17 may be a pipe welder of the prior art, which performs a circular weld by a track motion on an annular collar. However, the bottom of the integral bent pipe weldment in the device needs to be connected with the Z-direction lifting rod 5, so that the existing integral whole round bracket 11 cannot be sleeved outside the bent pipe weldment, and the integral whole round bracket 11 formed by splicing is arranged. When welding is not needed, the two parts are respectively moved in the linear displacement rail 9, and when welding is needed, the two parts are oppositely moved and spliced to form the whole-circle bracket 11 for the operation of the welding machine 17. Wherein the welder 17 can be stably arranged on half of the semicircular bracket 10.
Further, a plurality of teeth 12 are uniformly distributed on one side surface of the semicircular bracket 10, and the end parts of the semicircular brackets 10 on two sides are butted to form a whole circle which is sleeved outside the bent pipe weldment.
One side of the welding machine 17 is provided with a back-up slider 13, the other side is provided with a rotary gear set 14, the back-up slider 13 is in sliding connection with the semicircular bracket 10, the rotary gear set 14 is in meshed connection with the teeth 12, and the welding machine 17 drives the welding machine 17 to move circumferentially on the semicircular lantern ring through rotation of the rotary gear set 14.
The connection structure of the semicircular bracket 10 and the welding machine 17 can be as described above, and the welding machine 17 is driven to rotate on the semicircular bracket 10 by the engagement connection of the rotating gear set 14 and the teeth 12 and the rotation of the rotating gear set 14.
Further, the semicircular bracket 10 is mounted on the linear displacement rail 9 through the telescopic bracket 15, and the telescopic bracket 15 drives the semicircular bracket 10 to move towards the bent pipe weldment.
The semicircular bracket 10 is provided with a spacing observation assembly, the spacing observation assembly is electrically connected with the telescopic bracket 15, and the spacing observation assembly is used for measuring the distance between the semicircular bracket 10 and the bent pipe weldment in real time and controlling the extending length of the telescopic bracket 15 according to measurement data so as to match the positions of different bending depths of the bent pipe weldment.
When the linear displacement rails 9 are arranged on the outer side of the bent pipe weldment in two vertical straight lines, a plurality of bending positions with different degrees exist on the bent pipe weldment at the moment, so that the bending positions are different from the linear displacement rails 9 on the two sides, and the pushing lengths of the semicircular brackets 10 on the two sides are different when the semicircular brackets are mutually spliced and sleeved outside the bent pipe weldment, and the semicircular brackets are installed on the linear displacement rails 9 through the telescopic brackets 15.
The distance between the semicircular brackets 10 on two sides and the bent pipe weldment in the middle is observed through the distance observation assembly, so that the semicircular brackets 10 are driven to be stably spliced at the periphery of the bent pipe weldment.
Further, a visual sensor is arranged on the semicircular bracket 10, the visual sensor is electrically connected with the semicircular bracket 10, and the visual sensor is used for detecting different positions of the end faces of the inclined weld neck 2 on two sides of the bent pipe weldment and controlling the semicircular brackets 10 on two sides to move to the positions.
The semicircular bracket 10 is connected with the telescopic bracket 15 through the deflection assembly 16, and the deflection assembly 16 can enable the semicircular bracket 10 to rotate around a vertical straight line in the longitudinal direction so as to match the end faces of the welded junctions 2 with different inclination angles.
The deflection assembly 16 is electrically connected with the crater catcher or the visual sensor, and deflects according to the inclination angle of the end face of the crater 2 marked by the crater catcher or the visual sensor, so as to form a whole circle bracket 11 on the same plane with the crater 2 outside the bent pipe weldment.
In practice, for some non-standard elbow weldments, the tangent plane to the end port is sometimes at an oblique angle and is not straight. I.e. the individual craters 2 of the integral bent-tube weldment are not a transverse straight line but an oblique straight line in a plan view.
Therefore, the semicircular brackets 11 formed by mutually splicing the semicircular brackets 10 on the two sides are not parallel to the plane of the weld neck 2, so that the welding machine 17 cannot weld. Therefore, a visual sensor and deflection assembly 16 is provided on the semicircular bracket 10. Because the inclined port is shown on the bent pipe weldment, the positions of the welded junctions 2 on two sides of the bent pipe weldment are inconsistent, namely one is higher and one is lower, after the specific positions are scanned by the visual sensor, the semicircular supports 10 on two sides are driven to slide on the linear displacement rail 9 so as to reach the accurate positions (namely, the welded junction catcher is positioned to the central position of the inclined welded junction 2, the semicircular supports 10 are controlled to move to the central position, and the positions on two sides of the inclined welded junction 2 are different from the central position, namely one is higher and one is lower, so that the inclined welded junction 2 is scanned by the visual sensor at the moment, and the semicircular supports 10 are controlled to move to the positions after the specific positions on two sides of the inclined welded junction 2 are positioned.
When the semicircular brackets 10 on two sides are in place, the deflection assemblies 16 on the semicircular brackets 10 work at the moment, when the position of the welding port 2 is positioned by sliding the welding port catcher through the deflection assemblies 16 and the semicircular brackets 10, the inclination angle of the welding port 2 is calibrated, and meanwhile, the inclination angle is transmitted to the deflection assemblies 16, when the telescopic brackets 15 push the semicircular brackets 10 to move oppositely, the deflection assemblies 16 work at the same time, the deflection assemblies deflect to form the whole circular brackets 11 on the same plane with the end face of the welding port 2, and the welding machine 17 can work normally at the moment.
Specifically, the transverse crater 2 can be used as a reference angle to be input into the crater catcher in advance, the inclination angle of the actual crater 2 is scanned by the crater catcher, the inclination angle is compared with the reference angle to obtain a deviation angle, and finally the deviation angle is transmitted to the deflection assembly 16, so that the deflection assembly 16 can drive the semicircular bracket 10 to deflect by a correct angle.
The design is very convenient for non-standard welded pipes, irregular bent pipe weldments with different bending degrees and multiple bending parts, a worker does not need to adjust the welding head position of the welding machine 17, and the welding parts do not need to be inclined to match the welding head 17 position, so that the two welding parts are automatically contacted with each other, and the welding is finished.
In addition, the manner of deflecting the semicircular stent 10 described above is automatic, which is one embodiment of the present device, while another embodiment exists at the same time, which is manually adjusted by a worker. As will be described below,
As shown in fig. 4, a visual sensor is disposed on the semicircular bracket 10, and the visual sensor is electrically connected with the semicircular bracket 10, and is used for detecting different positions of the end surfaces of the inclined weld neck 2 on two sides of the bent pipe weldment, and controlling the semicircular brackets 10 on two sides to move to the positions.

The position of the bent pipe weldment is monitored in real time by utilizing an image positioning device 8, and the monitored bent pipe weldment is moved to be in butt joint with a reference bent pipe weldment to form the whole bent pipe weldment to be welded through a Z-direction lifting rod 5, an XY plane displacement platform 6 and an axial rotating structure 7;
the position of a weld neck 2 between adjacent bent pipe weldments is locked through a weld neck catcher, and the semicircular bracket 10 is controlled to drive the welding machine 17 to move to the position for welding;
