With the continuous development of science and technology, GIS equipment has been widely used in various fields, and GIS shell is a common GIS equipment shell. However, the GIS equipment shell needs to be installed with corresponding tooling before welding. GIS shell welding tooling is a general term for a series of special tooling fixtures and equipment used in the GIS (gas insulated switchgear) shell welding process to ensure welding accuracy, quality and efficiency.

The outer wall of the central ring 6 is fixedly connected with four slide bars 7 arranged at equal intervals around the axis of the driving rod 1. The outer wall of each slide bar 7 is provided with the same components. The outer wall of the slide bar 7 slides and is sleeved with a sleeve bar 8. The horizontal rod 32 passes through the interior of one of the slide bars 7. The top of the sleeve bar 8 is fixedly connected to the bottom end of the support plate 5. The outer wall of the sleeve bar 8 is fixedly connected with two symmetrical tooth plates 9. Two symmetrically distributed connecting plates 13 are fixedly connected to the outer wall of one side of the square box 12. A tooth column 10 is rotatably connected between the two connecting plates 13. The outer wall of the tooth plate 9 and the outer wall of the tooth column 10 are fixedly connected. The walls mesh with each other, and the ends of the two extraction rods 17 that are close to each other are fixedly connected with an integrated plate 18, and one end of the integrated plate 18 is fixedly connected with a tooth plate 2 14, and the outer wall of the tooth plate 2 14 meshes with the outer wall of the tooth column 10, and a rectangular slide 16 is provided at one end of the square box 12, and a stabilizing plate 15 is slidably connected between one end of the inner wall of the rectangular slide 16 and the tooth plate 2 14, and a bellows 19 is fixedly connected to the top of the square box 12, and the top of the bellows 19 is fixedly connected to the bottom end of the support plate 5, and two groups of connecting grooves are provided inside the support plate 5, and each group of connecting grooves includes two tubular grooves 20 symmetrically distributed in position The interiors of the two tubular grooves 20 are interconnected with the interior of the bellows 19, and the interiors of each negative pressure suction cup 21 are respectively interconnected with the interiors of the annular member 2.

Two connecting plates 3 are rotatably connected between the outer walls of the two short shaft rods, and the bottom end of the top connecting block 4 is movably connected to the top of the fastening plate 11.

[0031] When the motor is started, the rotation of the driving rod 1 will cause the two annular members 2 connected to it to rotate synchronously. The rotation tendency of the annular members 2 is restricted by the round block 24 and the horizontal rod 32, and the annular members 2 can only move in the horizontal direction with the rotation of the driving rod 1. Since the threads of the two thread grooves are opened in opposite directions, the two annular members 2 can only move in opposite directions. In the initial state, please refer to the attached manual. Figure 2 and 3At this time, the rotation of the driving rod 1 can only drive the two ring members 2 to move toward each other. Through the provided connecting piece, the distance between the support plate 5 and the driving rod 1 increases with the displacement of the two ring members 2, and then gradually approaches the inner wall of the GLS housing. In this process, the support plate 5 moves with the sleeve rod 8, and the two tooth plates 1 9 move together and rotate with the tooth column 10. The tooth plate 2 14 moves in the opposite direction at the same time. Under the connection of the integrated plate 18, the extraction rod 17 is extracted from the inside of the square box 12. It should be noted here that the extraction rod 17 is tightly fitted and slidably connected to the inside of the square box 12. Please refer to the attached manual for details. Figure 5 , the air inside the tubular groove 20 and the negative pressure suction cup 21 flows into the square box 12 through the bellows 19, thereby forming a negative pressure between the support plate 5 and the inner wall of the GLS shell, providing additional stabilizing force and greatly reducing the impact of shaking during welding. The setting of the stabilizing plate 15 and the rectangular slide groove 16 provides a basis for the stable displacement of the tooth plate 14.

[0032] For example 3, please refer to Figures 1 to 10, on the basis of the second embodiment, hollow blocks 26 are fixedly connected to the bottom ends of one of the fastening plates 11 and the fastening plate 23. A same partition plate 30 is fixedly connected between the inner walls of each of the hollow blocks 26. An oil storage sponge 29 is movably connected inside the hollow block 26. An extrusion block 28 is slidably connected inside the hollow block 26. The oil storage sponge 29 is movably connected to both the partition plate 30 and the extrusion block 28. One end of the extrusion block 28 is fixedly connected to a triangular block 27. The triangular block 27 is slidably connected to the inside of the hollow block 26. The bottom end of the extraction rod 17 is fixedly connected to a trapezoidal block 25. The trapezoidal block 25 is movably connected to the inclined end of the triangular block 27. Through grooves 37 are formed at the ends of the two annular members 2 away from each other. The outer wall of the horizontal rod 32 is slidably connected to the inside of the through groove 37. Two through openings 33 that are symmetrically distributed and away from each other are formed on the outer wall of the horizontal rod 32. Rack bars 34 are fixedly connected to the inside of the two through openings 33. The rack bars 34 pass through the inside of the through groove 37. Two mounting members 35 are fixedly connected to one end of the annular member 2. A long shaft rod is rotatably connected between the two mounting members 35. A column gear 36 is fixedly connected to the outer wall of the long shaft rod. The column gear 36 meshes with the rack bar 34. One end of the long shaft rod passes through one end of one of the mounting members 35 and is provided with a meshing gear member 38. The meshing gear member 38 includes a helical gear one and a helical gear two that mesh with each other. One end of the helical gear one is fixedly connected to one end of the long shaft rod. The helical gear two is rotatably connected to one end of the annular member 2. A flat gear 39 is rotatably connected to one end of the annular member 2. One end of the central axis of the flat gear 39 is rotatably connected to a C-shaped frame. The C-shaped frame is fixedly connected to one end of the annular member 2. A connection belt 40 is传动连接在the outer walls of the central axis of the flat gear 39 and the central axis of the helical gear two. An annular gear member 41 is rotatably connected to one end of the annular member 2. The outer walls of the flat gear 39 and the annular gear member 41 mesh with each other. A plurality of brushes are provided on the inner wall of the annular gear member 41. A plurality of through holes 42 that are equidistantly arranged around the axis of the driving rod 1 are formed on the outer wall of the annular gear member 41. One end of the partition plate 30 is fixedly connected and communicated with an oil outlet pipe 31. One end of the oil outlet pipe 31 is located on one side of the column gear 36. A straight rod for fixing the oil outlet pipe 31 is fixedly connected to one end of the annular member 2.

[0033] It should be noted that there is an unclear expression "传动连接在" in the original text which is tentatively translated as "传动连接在" for now. It might need to be further clarified and accurately translated according to the specific context.In the process of extracting the air inside the square box 12 by the extraction rod 17, the downward movement of the extraction rod 17 will drive the trapezoidal block 25 at its bottom end to move together. It should be noted here that only the fastening plate 11 and the fastening plate 23 above the ring member 2 are provided with a self-lubricating mechanism. Then, the inclined ends of the trapezoidal block 25 and the triangular block 27 conflict with each other, and the triangular block 27 is forced to move toward the inside of the hollow block 26, so that the extrusion block 28 squeezes the oil storage sponge 29. The oil storage sponge 29 stores lubricating oil in the initial state. When it is squeezed, the lubricating oil inside can only flow out through the only channel oil outlet pipe 31. It is explained in advance that the sides of the two hollow blocks 26 are provided with through-shaped circular holes, which are used for the replenishment of lubricating oil. When the ring member 2 is displaced, the displacement of the ring member 2 drives the column gear 36 through the rack 34 and the column gear 36. When the gear 36 rotates, the meshing gear part 38 will also rotate at the same time. Through the transmission connection of the connecting belt 40, the flat gear 39 rotates and drives the annular gear part 41 to operate. The lubricating oil flowing out of the oil outlet pipe 31 will directly drip onto the tooth block part of the column gear 36 and the annular gear part 41. As the annular part 2 moves, the lubricating oil on the column gear 36 will be transferred to the tooth surface of the rack 34, thereby improving the smoothness of the meshing. A part of the lubricating oil dripping on the tooth block part of the annular gear part 41 will directly pass through the through hole 42 and then be transferred to the brush. The brush will synchronously lubricate and wipe the threaded groove on the annular part 2 as the annular gear part 41 rotates, replacing manual maintenance work. Moreover, this function is completed synchronously before the welding work, that is, when the inner wall of the GLS housing is clamped, killing two birds with one stone and improving the efficiency of the preparation work.

[0034] In actual use, when the motor is started, the rotation of the drive rod 1 can only drive the two ring members 2 to move toward each other. Through the provided connecting piece, the distance between the support plate 5 and the drive rod 1 increases with the displacement of the two ring members 2, and then gradually approaches the inner wall of the GLS shell. In this process, the support plate 5 moves together with the sleeve rod 8, and the two tooth plates 1 9 move together and rotate with the tooth column 10. The tooth plate 2 14 moves in the opposite direction at the same time. Under the connection of the integrated plate 18, the extraction rod 17 is extracted from the inside of the square box 12, and then a negative pressure is formed between the support plate 5 and the inner wall of the GLS shell, providing additional stabilizing force, which greatly reduces the impact of shaking during welding. The setting of the stabilizing plate 15 and the rectangular slide groove 16 provides a basis for the stable displacement of the tooth plate 2 14. In the above process, the downward movement of the extraction rod 17 will drive the trapezoidal block 25 at its bottom end to move together, and then the inclined ends of the trapezoidal block 25 and the triangular block 27 conflict with each other. The triangular block 27 is forced to move toward the inside of the hollow block 26, so that the extrusion block 28 squeezes the oil storage sponge. 29. The oil storage sponge 29 stores lubricating oil in the initial state. When it is squeezed, the lubricating oil inside can only flow out through the only channel oil outlet pipe 31. The displacement of the ring member 2 drives the column gear 36 to rotate. At the same time, the meshing gear member 38 will also rotate. Through the transmission connection of the connecting belt 40, the flat gear 39 rotates and drives the ring gear member 41 to operate. The lubricating oil flowing out of the oil outlet pipe 31 will directly drip onto the tooth block part of the column gear 36 and the ring gear member 41. As the ring member 2 is displaced, The lubricating oil on the column gear 36 will be transferred to the tooth surface of the rack 34, improving the smoothness of meshing. A part of the lubricating oil dripping on the tooth block part of the ring gear part 41 will directly pass through the through hole 42 and then be transferred to the brush. The brush will lubricate and wipe the threaded groove on the ring part 2 synchronously with the rotation of the ring gear part 41, replacing manual maintenance work. This function is completed synchronously before the welding operation, that is, when clamping the inner wall of the GLS shell, killing two birds with one stone and improving the efficiency of the preparation work.
