Description

Technical Field

[0001] The invention relates to the technical field of post-welding processing, and in particular to a stabilizing and heat-insulating device for a welding carriage. Background Art

[0002] The foundation ring is a critical component connecting the fan cylinder to the foundation. In many currently installed fans, the flange thickness of the foundation ring is thinner than the cylinder wall, creating a weak link in the foundation ring. To improve the overall load-bearing capacity of the foundation ring, one method is to cut away the weak area of the old flange and then weld a new, reinforced flange. This can be accomplished using a welding trolley.

[0003] After welding, the cylinder is prone to residual welding stress and deformation due to rapid cooling, which in turn causes cracking problems, especially in winter. The current method for relieving stress is to perform manual stress relief after welding, which is time-consuming and labor-intensive. Summary of the Invention

The weld after welding is insulated at multiple levels through a first heating and insulation device, a second heating and insulation device, and a third heating and insulation device. The flame of the heating device near the welding device is the largest, and as the distance from the welding device increases, the flame of the heating device gradually decreases, thereby ensuring that the weld can be gradually and steadily cooled.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0024] like Figure 2 As shown, a welding trolley stable insulation device includes a driving trolley 1, a driving wheel 2 is installed on the driving trolley 1, and the driving trolley 1 moves on the outer surface of the cylinder 3 through the driving wheel 2. One end of the welding gun fixing plate 5 is fixedly connected to the surface of one side of the driving trolley 1, and the other end of the welding gun fixing plate 5 is provided with a sleeve 4. A welding device 6 is sleeved in the sleeve 4, and the welding end of the welding device 6 is located on the cylinder 3; one end of the adjusting rod 7 is fixedly connected to the surface of the other side of the driving trolley 1, and the outer surface of the adjusting rod 7 is slidably connected to the first sliding member 8 and the second sliding member 9. and the third sliding member 10, the first sliding member 8, the second sliding member 9 and the third sliding member 10 are all provided with a fixing sleeve 11, the first sliding member 8 is equipped with a first heating and heat preservation device 12 through the fixing sleeve 11, the second sliding member 9 is equipped with a second heating and heat preservation device 13 through the fixing sleeve 11, and the third sliding member 10 is equipped with a third heating and heat preservation device 14 through the fixing sleeve 11, and the flames of the first heating and heat preservation device 12, the second heating and heat preservation device 13 and the third heating and heat preservation device 14 decrease successively as the distance from the welding device 6 increases.

[0025] Before working, first adjust the vertical position of the welding device 6 in the sleeve block 4 and the vertical placement positions of the first heating and heat preservation device 12, the second heating and heat preservation device 13 and the third heating and heat preservation device 14, so that the welding end of the welding device 6 and the heat preservation flames of the first heating and heat preservation device 12, the second heating and heat preservation device 13 and the third heating and heat preservation device 14 correspond to the positions required for welding and heat preservation on the surface of the cylinder 3, and then adjust the horizontal spacing between the first sliding member 8, the second sliding member 9 and the third sliding member 10 to ensure that the heating flame gradually decreases as the distance from the welding device 6 increases; then start the welding. The connecting device 6 and the first heating and heat preservation device 12, the second heating and heat preservation device 13 and the third heating and heat preservation device 14, and at the same time give the driving trolley 1 an electrical signal, so that the driving wheel 2 drives the driving trolley 1 to move along the cylinder 3. During the movement, the welding device 6 performs welding processing, and then the first heating and heat preservation device 12, the second heating and heat preservation device 13 and the third heating and heat preservation device 14 are used to perform multi-stage insulation on the weld after welding, thereby achieving a gradual and steady cooling effect; in this embodiment, the number of heating and heat preservation devices can also be increased or decreased according to the insulation needs to ensure that the weld is cooled steadily.

[0026] Embodiment 2, based on further improvement of embodiment 1, the adjustment rod 7 includes a fixed adjustment rod 71 and a sliding adjustment rod 72. One end of the fixed adjustment rod 71 is fixed to the side surface of the driving trolley 1. A sliding groove 73 is provided on the inner side of the fixed adjustment rod 71. The sliding adjustment rod 72 is slidably connected to the inner surface of the sliding groove 73. The first sliding member 8 and the second sliding member 9 are both slidably connected to the outer surface of the fixed adjustment rod 71. The third sliding member 10 is connected to the surface of the sliding adjustment rod 72. A limit block 74 is fixedly installed on the end of the fixed adjustment rod 71 and the sliding adjustment rod 72 away from the driving trolley 1. A limit screw 75 is provided on the end of the fixed adjustment rod 71 away from the driving trolley 1. A plurality of threaded holes 76 are evenly provided on the surface of the sliding adjustment rod 72. The limit screws 75 match the threaded holes 76. Therefore, when in use, the length of the adjusting rod 7 is adjusted by sliding the adjusting rod 72 in the sliding groove 73, so that the stability of the adjusting rod 7 can be improved by controlling the length of the adjusting rod 7 to prevent the adjusting rod 7 from being broken or damaged due to being too long, and it is also convenient to adjust the third sliding member 10; and after the adjustment, the limiting screw 75 is matched with the threaded hole 76 to fix the sliding adjusting rod 72 after adjustment.

[0027] In the third embodiment, based on a further improvement on the first embodiment, one end of a connecting plate 15 is fixedly mounted on the upper surface of the driving trolley 1, and a welding slag isolation and collection box 16 is fixedly mounted on the other end of the connecting plate 15. The welding slag isolation and collection box 16 is located on the inner surface of the cylinder 3 and is slidably connected to the cylinder 3 via a curved slider. Therefore, during welding or torch cutting, the welding slag isolation and collection box 16 inside the cylinder 3 can collect welding slag and prevent it from falling into the cylinder 3 and damaging the equipment inside the cylinder 3. The welding slag isolation and collection box 16 also limits the running path of the driving trolley 1, ensuring that the driving trolley 1 can move along the cylinder 3 without deviation.

[0028] Embodiment 4, based on further improvement of embodiment 1, is provided with an adjusting screw sleeve 17 above the fixing sleeve 11, and a retaining groove 18 is provided above the inner surface of the fixing sleeve 11. The lower end of the adjusting screw sleeve 17 is movably connected in the retaining groove 18. The inner surface of the adjusting screw sleeve 17 is provided with a thread. The first heating and heat preservation device 12, the second heating and heat preservation device 13, and the third heating and heat preservation device 14 all pass through the adjusting screw sleeve 17 and are connected to the adjusting screw sleeve 17 by threads. Therefore, when it is necessary to adjust the vertical position of the first heating and heat preservation device 12, the second heating and heat preservation device 13, and the third heating and heat preservation device 14, by rotating the adjusting screw sleeve 17, the first heating and heat preservation device 12, the second heating and heat preservation device 13, and the third heating and heat preservation device 14 can be moved up and down on the inner surface of the adjusting screw sleeve 17 by utilizing the principle of the screw thread, so as to achieve the adjustment and fixing effect.

[0029] In a fifth embodiment, based on a further improvement on the first embodiment, a welding device 6 includes a height adjustment rod 61 and a welding gun 62. The height adjustment rod 61 is movably connected within the sleeve 4 and locked in place by a locking pin. An angle adjustment device 63 is fixedly mounted at the end of the height adjustment rod 61. The side surface of the angle adjustment device 63 is movably connected to the welding gun 62 via a rotating rod. Thus, before welding, the height adjustment rod 61 is first adjusted in position within the sleeve 4, then locked in place by the locking pin, and the welding angle of the welding gun 62 is adjusted via the angle adjustment device 63. The angle adjustment device 63 includes a fixed block 64 having a groove 65 formed on its surface. A limiting groove 66 is formed within the inner surface of the groove 65. One end of a spring 67 is fixedly mounted within the limiting groove 66. The other end of the spring 67 is fixedly connected to one end of a limiting block 68. A gear 69 is fixedly connected to the end of the rotating rod. The rotating rod is rotatably connected within the groove 65 via the gear 69. The other end of the limiting block 68 meshes with the teeth on the circumference of the gear 69. Therefore, when it is necessary to adjust the inclination angle of the welding gun 62, the rotating rod is rotated to rotate the gear 69 at the end of the rotating rod in the groove 65. When rotating at a certain angle, the limiting block 68 in the limiting groove 66 will engage with the teeth on the circumference of the gear 69 through the elastic force of the spring 67. Therefore, when it is rotated to a suitable angle, the angle of the rotating rod can be limited by the limiting block 68. Moreover, since the end of the limiting block 68 is a conical structure, when the rotating rod is rotated, the gear 69 can smoothly squeeze the limiting block 68 into the limiting groove 66 again along the conical edge to facilitate angle adjustment.

[0030] In the sixth embodiment, based on a further improvement on the first embodiment, a curved slider is fixedly mounted on the contact surface between the driving carriage 1 and the device to be cut. Thus, when the driving carriage 1 moves, the curved slider prevents the driving carriage 1 from rubbing against the surface of the device to be cut, thereby causing damage. Furthermore, the curved structure also prevents damage to the surface of the device to be cut due to sharp corners.
