DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a welding processing device for a steam turbine diaphragm provided by an embodiment of the present invention includes a plurality of conveying components 1, wherein the conveying components 1 are used to convey a diaphragm body 4, a nozzle stationary blade 5, and a diaphragm outer edge 6 respectively, and further includes:

[0028] The suspension assembly component 2, the conveying components 1 are arranged at intervals, and the suspension assembly component 2 is located at the end of multiple conveying components 1, the suspension assembly component 2 includes two frames 201 arranged at intervals, and a first beam frame 202, a second beam frame 203 and a third beam frame 204 are arranged between the two frames 201, and the first beam frame 202, the second beam frame 203 and the third beam frame 204 are all composed of two cross beams 2021 arranged at intervals, and the two ends of the cross beam 2021 are connected to the two frames 201, and the cross beams 2021 are all symmetrically arranged about the suspension assembly component 2, and the cross beams 2021 are all located at the top of the conveying component 1 and are perpendicular to the conveying component 1. The spacing between the two cross beams 2021 in the first beam frame 202, the second beam frame 203 and the third beam frame 204 is set in increasing order according to the size of the partition, the first beam frame 202 is provided with a first movable grab assembly 205, the second beam frame 203 is provided with a second movable grab assembly 206, and the third beam frame 204 is provided with a third movable grab assembly 207. The first movable grab assembly 205 is used for lateral movement of the partition body 4 on the conveying component 1, the second movable grab assembly 206 is used for driving the nozzle stationary blade 5 on the conveying component 1 to lateral movement, and the third movable grab assembly 207 is used for driving the outer edge 6 of the partition on the conveying component 1 to lateral movement;

[0029] The welding support component 3 is located at the bottom of the cross beam 2021 and is arranged away from the conveying component 1. The welding support component 3 includes a transverse conveying component 301. A carrying platform 302 is fixedly connected to the transverse conveying component 301. A welding base 303 for carrying the partition is provided on the carrying platform 302. When the first movable grasping component 205, the second movable grasping component 206 and the third movable grasping component 207 respectively move the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 to the positions corresponding to the welding base 303, the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 are in the same vertical plane.

[0030] In one embodiment of the present invention, when the present invention is in use, the three parts of the partition body 4, the nozzle stator 5 and the partition outer edge 6 of the partition are firstly synchronously conveyed by the conveying component 1, and then the three parts are grasped by the first movable grasping component 205, the second movable grasping component 206 and the third movable grasping component 207. Since the position spacing of the crossbeam 2021 is set according to the size of the partition, when the partition body 4, the nozzle stator 5 and the partition outer edge 6 rise to the same conveying height, the three will be aligned but staggered. When all three are moved to the top of the welding support component 3, the partition body 4, the nozzle stator 5 and the partition outer edge 6 will be directly docked and assembled into a turbine partition, and then they can be directly placed on the welding base 303 for welding. First, the three parts can be conveyed synchronously without interference, which can significantly improve the conveying efficiency. In the conveying process, the three parts can be automatically aligned, eliminating the adjustment work during welding, and the overall welding efficiency is improved through the above two aspects.

[0031] In an example of the present invention, it should be noted that the first movable grasping assembly 205, the second movable grasping assembly 206 and the third movable grasping assembly 207 are not used to grasp the main body of the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6, because in the actual processing process, in order to facilitate transportation, the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 are usually welded with lifting ears, so the first movable grasping assembly 205, the second movable grasping assembly 206 and the third movable grasping assembly 207 act on the lifting ears of the workpiece, such as Figure 4 and Figure 6As shown, the first movable grabbing assembly 205 includes a movable seat 2051 arranged on two cross beams 2021, and a vertically arranged telescopic member 2052 is fixedly connected to the bottom of the movable seat 2051, and a manipulator 2053 for grabbing the two ends of the partition body 4 is arranged at the other end of the telescopic member 2052. The second movable grabbing assembly 206 and the third movable grabbing assembly 207 have the same structure as the first movable grabbing assembly 205, and both are provided with the movable seat 2051, the telescopic member 2052 and the manipulator 2053. The movable seat 2051 is used to drive the corresponding telescopic member 2052 and the manipulator 2053 to move back and forth laterally between the frames 201. The initial position of the movable seat 2051 in the first movable grabbing assembly 205, the second movable grabbing assembly 206 and the third movable grabbing assembly 207 corresponds to the position of the conveying component 1. Therefore, it can be obtained that the manipulator 2053 acts on the partition body 4, the nozzle stator 5 and the outer edge 6 of the partition. The conveying component 1 can adopt an existing commonly used conveying device, and a limiting structure 7 needs to be set on the conveying component 1 to convey the corresponding workpiece, so that the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 are all in an open upward state, so as to facilitate the grasping of the manipulator 2053. The telescopic member 2052 can be in the form of an electric telescopic rod, and of course it can also be in the form of a hydraulic telescopic rod, mainly to be able to drive the manipulator 2053 to move up and down, and because it is a suspended transportation, the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 themselves can maintain a horizontal state. Therefore, as long as the length of the telescopic member 2052 can be guaranteed to be consistent during transportation, the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 can be positioned, and the three only need to move horizontally to complete the docking.

[0032] like Figure 4 As shown, as a preferred embodiment of the present invention, two sliding installation grooves 8 are arranged at intervals along the length direction of the conveying component 1 on the top of the frame 201, and the two ends of the beam 2021 are respectively slidably connected to the sliding installation grooves 8 of the two frames 201, and an adjustment assembly box 9 is arranged on one side of the frame 201. The adjustment assembly box 9 is used to adjust the distance between the two beams 2021 in the first movable grasping assembly 205, the second movable grasping assembly 206 and the third movable grasping assembly 207. The minimum distance between two adjacent beams 2021 on the same side of the frame 201 is greater than the width of the movable seat 2051.

[0033] In one case of the present embodiment, the frame 201 is provided with a total of six beams 2021, and the beams 2021 are grouped in pairs, and the positions of the beams 2021 themselves and the spacing between the beams 2021 facilitate direct correlation with the size of the turbine partition. In actual situations, the sizes of the turbine partitions that may need to be welded are different, so the position of the beam 2021 can be adjusted by adjusting the assembly box 9. A plurality of groups of electric telescopic rods can be arranged in the adjustment assembly box 9 to adjust the position of the beam 2021, so that the positions of the manipulators 2053 in the first movable grasping assembly 205, the second movable grasping assembly 206 and the third movable grasping assembly 207 can all correspond to the corresponding workpiece positions, ensuring that the partition body 4, the nozzle stator 5 and the partition outer edge 6 can be stably transported laterally, and the minimum spacing between two adjacent beams 2021 is greater than the width of the moving seat 2051, which can avoid interference between adjacent moving seats 2051 when the moving seat 2051 moves on the beam 2021.

[0034] like Figure 4 , Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, one side of the moving seat 2051 in the first moving grab assembly 205 is fixedly connected with an annular blocking plate 10, all the beams 2021 located on the same side of the frame 201 in the first moving grab assembly 205, the second moving grab assembly 206 and the third moving grab assembly 207 are located in the annular blocking plate 10, and the length of the annular blocking plate 10 is greater than the length of the sliding mounting groove 8, when the moving seat 2051 in the first moving grab assembly 205 moves on the beam 2021, the annular blocking plate 10 is used to push the second moving grab assembly 206 to move. The moving seats 2051 in the first moving grab assembly 205, the second moving grab assembly 206 and the third moving grab assembly 207 move synchronously, and when the annular blocking plate 10 is in contact with the moving seats 2051 in the second moving grab assembly 206 and the third moving grab assembly 207, the moving seats 2051 in the first moving grab assembly 205, the second moving grab assembly 206 and the third moving grab assembly 207 are flush; the adjacent moving seats 2051 on the same side beam 2021 of the frame 201 are connected by cables 11, and the length of the cables 11 is set according to the spacing between the corresponding conveying components 1.

[0035] In one case of the present embodiment, the driving method of the moving seat 2051 is not specifically mentioned. If each moving seat 2051 needs an independent power source to drive it, it will be very complicated. The present embodiment takes into account the movement characteristics of the moving seat 2051. Therefore, as long as a driving member 13 is provided on the moving seat 2051 of the first moving grabbing assembly 205 to drive the moving seat 2051 to move horizontally, the driving member 13 can be in the form of an electric motor or a hydraulic motor. Through the above structure, the first moving grabbing assembly 205, the second moving grabbing assembly 206 and the third moving grabbing assembly 207 can form an effective linkage. When the manipulator 2053 grabs the corresponding workpiece, the moving seat 2051 in the first moving grabbing assembly 205 is first moved horizontally. When the annular blocking plate 10 contacts the moving seat 2051 in the second moving grabbing assembly 206, it will push it to move. When the annular blocking plate contacts the moving seat 2051 in the third moving grabbing assembly 207, a one-pushing-two pattern can be formed, so that the six moving seats 2051 can move as a whole. In this way, the partition body 4, the nozzle stationary blade 5 and the partition outer edge 6 can be automatically aligned. There is no need to control the specific position of a single moving seat 2051 to adjust the docking process of the three. In addition, due to the existence of the cable 11, when the moving seat 2051 is returning to the initial position, as long as the moving seat 2051 in the first moving grabbing assembly 205 can return to the initial position, the remaining moving seats 2051 can return to the corresponding initial positions. Figure 6 As shown, a reel-up box 12 is fixedly connected to the top of the movable seat 2051, and a section of the cable 11 is connected to the reel-up box 12. The reel-up box 12 is used to adjust the length of the cable 11 between the movable seats 2051. In actual situations, due to space limitations, the conveying components 1 may not be able to be placed at equal intervals, so that the partition body 4, the nozzle stationary blades 5 and the outer edge of the partition 6 may also change. Therefore, the length of the cable 11 can be controlled by the reel-up box 12 to adjust the initial position of the movable seat 2051. The reel-up box 12 can be used to reel in the cable 11, and can also be locked after reeling to ensure that the length of the cable 11 does not change.

[0036] like Figure 3 and Figure 7As shown, as a preferred embodiment of the present invention, the transverse conveying assembly 301 includes two guide rails 3011 arranged at intervals, and a driving seat 3012 is slidably arranged on each of the guide rails 3011 on both sides, and a carrying platform 302 is arranged on the top of the driving seat 3012, and the driving seat 3012 is used to drive the carrying platform 302 to move on the guide rails 3011, and the carrying platform 302 includes a rotating base 3021 connected to the driving seat 3012, and a rotating platform 3022 is rotatably arranged on the top of the rotating base 3021, and the welding base 303 is located on the rotating platform 3022, and the rotating base 3021 is used to drive the rotating platform 3022 to rotate.

[0037] In one case of the present embodiment, the welding base 303 is composed of two relatively arranged arc blocks 3031, and a spacing adjustment seat 14 is arranged on the rotating platform 3022. The two arc blocks 3031 are located on the spacing adjustment seat 14, and the spacing adjustment seat 14 is used to adjust the spacing between the two arc blocks 3031. The driving seat 3012 and the rotating platform 3022 are both provided with corresponding power sources. The rotating platform 3022 itself can rotate, so that the turbine partition composed of the partition body 4, the nozzle stator 5 and the partition outer edge 6 can be rotated, which is convenient for double-sided welding processing. The spacing adjustment seat 14 can adjust the spacing of the arc blocks 3031 to ensure that the arc blocks 3031 can support turbine partitions of different sizes. After the welding is completed, the driving seat 3012 will drive the turbine partition to move out, so that the various steps of the turbine partition welding process are more closely connected.

[0038] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention.
