Description

Technical Field

[0001] The utility model relates to the field of pipeline welding, in particular to an integrated workbench for pipeline butt welding. Background Art

[0002] Laying pipes is a very common task in various construction scenarios. In order to facilitate transportation, pipes are usually cut into fixed lengths and re-welded and assembled at the construction site.

[0003] Many pipeline laying operations are carried out outdoors, where uneven roads and difficult passage of mechanical equipment are common problems. Therefore, most pipeline docking work is done manually. When welding the pipelines, the tail end of pipe A and the head end of pipe B must be docked, and the welding torch must then be moved around the joint for welding. Therefore, the joint end must be lifted to provide space for the welding torch to work at the bottom. After the docking is completed, an operator is required to maintain the stability of the pipeline and another operator is required to weld the pipeline, requiring multiple people to operate simultaneously, wasting manpower. Utility Model Content

[0004] The utility model aims to provide an integrated workbench for butt welding of pipelines, which has the advantage of being suitable for completing butt welding work of pipelines in the field.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: an integrated pipe butt welding workbench, comprising:

[0006] a platform on which a crawler belt and a controller are mounted;

[0007] a lifting assembly provided on the platform, the lifting assembly being used to apply pressure to the ground from the peripheral side of the platform so that the platform is tilted up by the reverse lifting force;

[0008] a splicing module disposed on the platform and controlled by the controller, for grabbing tube a and tube b and splicing the tail end of tube a with the head end of tube b; and

[0009] A welding module is arranged on the table and controlled by the controller, and is used for surrounding and welding the interface of tube a and tube b to fix it.

[0010] Through the above technical solution, the crawler drives the table to move, so that the workbench can move on the ground in the field. When the ground is uneven and the crawler cannot pass through, or the crawler is stuck in a pit on the ground and cannot move, the lifting component lifts the table by applying pressure to the ground, thereby improving the workbench's ability to cross obstacles or enabling the workbench to move out of the pit, so that the workbench has a strong passability in the field. After reaching the preset working position, the splicing module will grab pipe a and pipe b under the control of the controller and realize the splicing of pipe a and pipe b. Then the controller controls the welding module to weld and fix the interface of pipe a and pipe b. This solution uses automated control to weld and fix the pipeline, which can significantly reduce the number of operators required for butt welding and reduce the manpower requirements during the pipeline splicing and welding process.

[0011] In one embodiment of the present invention, the lifting assembly includes: a turntable rotatably connected to the table; a lifting arm installed on the turntable, the lifting arm consisting of several sections hinged in pairs so that the end of the lifting arm can extend to the side of the table to apply pressure to the ground, the turntable drives the lifting arm to rotate, thereby changing the downward position of the lifting arm, so that the table can be tilted from different directions.

[0012] Through the above technical solution, the lifting arm can be folded and extended, folded and contracted to reduce space occupation when not in use, and unfolded to lift the table when in use.

[0013] In one embodiment of the present invention, the splicing module includes:

[0014] A driving mechanism a controlled by the controller for grabbing tube a and adjusting and calibrating the axial direction of tube a; a driving mechanism b controlled by the controller for grabbing tube b and adjusting the axial direction of tube b to be parallel to the axial direction of tube a; and a three-dimensional scanner electrically connected to the controller for scanning the leading end position of tube b and the trailing end position of tube a to obtain the difference between the two positions. The controller then controls the driving mechanism b to drive tube b to move a distance that eliminates the difference so that tube a and tube b can be spliced ​​together.

[0015] Through the above technical solution, the controller controls drive mechanism a and drive mechanism b to grab tube a and tube b respectively, so that tube a is parallel to tube b. After they are parallel, the three-dimensional scanner scans the leading end position of tube b and the trailing end position of tube a. After obtaining the difference between the two positions, the controller controls drive mechanism b to move a distance to eliminate the difference, thereby splicing tube a and tube b.

[0016] In one embodiment of the present invention, the driving mechanism a includes: at least two first clamps for grasping tube a; a first x-axis driving member for driving the first clamp to move along the x-axis direction; a first y-axis driving member for driving the first clamp to move along the y-axis direction; and a first z-axis driving member for driving the first clamp to move along the z-axis direction. The controller is preset with an initial coordinate position of each first clamp, and the controller records the driving stroke of the first x-axis driving member, the first y-axis driving member and the first z-axis driving member to obtain the final coordinate position of the first clamp. The controller can obtain the axial direction of the tube a by combining the coordinate positions of the two first clamps.

[0017] Through the above technical solution, the final coordinate position of each first clamping jaw can be obtained, and the axial direction of tube a can be obtained by combining the coordinate positions of the two first clamping jaws.

[0018] In one embodiment of the present invention, the driving mechanism b includes: at least two second clamps for grasping tube b; a second x-axis driving member for driving the second clamp to move along the x-axis direction; a second y-axis driving member for driving the second clamp to move along the y-axis direction; and a second z-axis driving member for driving the second clamp to move along the z-axis direction. After the three-dimensional scanner obtains the difference between the head end of tube b and the tail end of tube a, the controller controls the second x-axis driving member, the second y-axis driving member and the second z-axis driving member to respectively drive the second clamp to move along the x-axis, y-axis and z-axis directions by a distance to eliminate the difference.

[0019] Through the above technical solution, the second x-axis driving member, the second y-axis driving member and the second z-axis driving member drive the second clamp to move along the x-axis, y-axis and z-axis directions, thereby freely adjusting the position of tube b so that tube b is spliced ​​with tube a.

[0020] In one embodiment of the present invention, the platform is equipped with a robotic arm, which is used to drive the three-dimensional scanner to circumferentially circle around the head end of the b tube and the tail end of the a tube to obtain the position difference between the head end of the b tube and the tail end of the a tube.

[0021] Through the above technical solution, the robotic arm drives the three-dimensional scanner to perform multi-angle scanning on the head end of tube b and the tail end of tube a, thereby comprehensively obtaining the coordinate differences of the head end of tube b and the tail end of tube a along different directions.

[0022] In one embodiment of the present invention, the welding module includes: a welding support frame installed at the end of the robotic arm, the robotic arm drives the welding support frame to move; a welding drive mechanism installed on the welding support frame; and a welding gun driven by the welding drive mechanism to weld around the joint of pipe a and pipe b.

[0023] Through the above technical solution, the robotic arm drives the welding support frame to move, so as to move the muzzle of the welding gun to the joint of pipe a and pipe b, and then the welding drive mechanism drives the welding gun to circle the interface to weld and fix the interface.

[0024] In one embodiment of the present invention, the welding drive mechanism includes: an opening and closing drive component; a first track and a second track that are driven by the opening and closing drive component to be assembled and combined to form a circular track when assembled; a surrounding drive component; and a surrounding frame that is driven by the surrounding drive component to slide along the path of the first track and the second track, and the welding gun is mounted on the surrounding frame.

[0025] Through the above technical solution, after pipe a and pipe b are docked, the opening and closing drive assembly drives the first track and the second track to open, and the robotic arm drives the first track and the second track to move, so that the pipe passes through the disconnection point between the first track and the second track and reaches the middle position of the first track and the second track. Thereafter, the opening and closing drive assembly drives the first track and the second track to close so that the first track and the second track are arranged around the pipe, and the surrounding drive assembly drives the surrounding frame to move along the circular track composed of the first track and the second track, so that the welding gun surrounds the pipe to weld the pipe. This solution uses a mechanical mechanism to drive the welding gun to surround the pipe to weld the pipe, replacing manual labor to efficiently weld the pipe.

[0026] In one embodiment of the present invention, the opening and closing drive assembly includes: a driven gear, a first screw and a second screw with opposite thread directions are fixed on both sides of the driven gear, the first screw and the second screw are rotatably connected to the welding support frame, the first screw is threadedly connected to a first slider fixedly connected to the first track, and the second screw is threadedly connected to a second slider fixedly connected to the second track; an opening and closing drive member drives the driven gear to rotate reciprocally so that the first slider and the second slider move toward or in opposite directions to achieve the splicing and separation of the first track and the second track.

[0027] Through the above technical solution, the opening and closing drive member drives the driven gear to rotate, and the driven gear will drive the first screw and the second screw to rotate when rotating. Since the threads of the first screw and the second screw are set in opposite directions, the first slider and the second slider will move towards each other or in opposite directions, thereby driving the first track and the second track to separate or splice.

[0028] In one embodiment of the present invention, the surround drive assembly includes: a surround drive member installed on the surround frame; a surround gear driven to rotate by the surround drive member; and a ring gear installed separately on the first track and the second track, wherein the first track and the second track form a complete ring gear when they are assembled, and the surround gear is engaged with the ring gear.

[0029] Through the above technical solution, the surrounding drive member drives the surrounding gear to rotate, and the surrounding gear moves along the ring gear, thereby driving the surrounding frame to move on the first track and the second track, so that the welding gun moves around the pipe.

[0030] As described above, the integrated pipe butt welding workbench of the present invention has the following beneficial effects:

[0031] The crawler tracks drive the table to move, so that the workbench can move on the ground in the field. When the ground is uneven and the crawler tracks cannot pass through, or the crawler tracks are stuck in a pit on the ground and cannot move, the lifting assembly lifts the table by applying pressure to the ground, thereby improving the workbench's ability to cross obstacles or enabling the workbench to move out of the pit, so that the workbench has a strong passability in the field. After reaching the preset working position, the splicing module will grab pipe a and pipe b under the control of the controller and realize the splicing of pipe a and pipe b. Then the controller controls the welding module to weld and fix the interface of pipe a and pipe b. This solution uses automated control to weld and fix the pipeline, which can significantly reduce the number of operators required for butt welding and reduce the manpower requirements during the pipeline splicing and welding process.

[0050] A coordinate origin is preset in the controller.

The controller records the driving stroke of the first x-axis driver 18, the first y-axis driver 431 and the first z-axis driver 432.

[0051] The specific principle of the controller controlling the driving mechanism b5 to drive the b tube 17 to move so that the b tube 17 is parallel to the a tube 16 is as follows: the final coordinate positions of the two first grasping members are (x1, y1, z1) and (x2, y2, z2) respectively.

After calculating the desired coordinate positions of the two second grasping members, the controller controls the two groups of second y-axis driving members 531 and the second z-axis driving members 532 to drive the two second grasping members to reach the desired coordinate positions.

The three-dimensional scanner is electrically connected to the controller so that the controller obtains the information obtained by the three-dimensional scanner, and after obtaining the difference, controls the second y-axis drive member 531, the second z-axis drive member 532, and the second x-axis drive member 19 to work so that the b tube 17 moves the corresponding difference to be spliced ​​with the a tube 16, and the a tube 16 does not move to prevent the a tube 16 from being separated from the laid pipeline.
