[0002] The structure of an air-cooling tower is usually composed of steel columns, support rods, beams, etc., among which the double-column foot node is the connecting part between the supporting steel column and the foundation or beam.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] Reference Figures 1-9 The present invention provides a technical solution: a double-column foot node welding mechanism for an air-cooling tower, comprising a main box 1, a mounting column 2 being fixedly mounted on the top surface of the main box 1, an external frame 3 being fixedly mounted on the top of the mounting column 2, an electric telescopic rod 4 being mounted inside the external frame 3, a top plate 6 being arranged below the electric telescopic rod 4, a rotary welding assembly 13 being arranged on the top surface of the main box 1, a pillar 7 being placed inside the main box 1, a top frame 10 being fixedly mounted on the top surface of the main box 1, the top frame 10 being a hollow structure, and a display panel 8 and an emergency stop button 9 being mounted on the front surface of the main box 1;

[0039] The rotary welding assembly 13 includes a gear disc 1301, which is rotatably mounted on the outer surface of the top frame 10. Four extension frames 1302 are fixedly mounted on the inner side of the gear disc 1301. The interiors of the four extension frames 1302 are movably connected with a clamping block 1303. The tops of the two symmetrical clamping blocks 1303 are respectively installed with a mounting plate 1 1304 and a mounting plate 2 1306. A welding machine 1305 is installed on the top surface of the mounting plate 1 1304, and a mounting column 2 1309 is installed on the top surface of the mounting plate 2 1306. The rotary welding assembly 13 is configured for rotary welding of the top plate 6 and the pillar 7.

[0040] The inner side of the clamping block 1303 is fixedly installed with a mounting seat 1307, and the four mounting seats 1307 are connected by multiple connecting rods 1308. An electric telescopic rod three is fixedly installed between the one side surface of two symmetrical clamping blocks 1303 and the inner side surface of the extension frame 1302. An equipment box 11 is fixedly installed on the one side surface of the main box 1. A motor is arranged inside the equipment box 11. A gear 12 is fixedly installed on the output end of the motor. The gear 12 and the gear disc 1301 are engaged with each other. A plug-in column 1310 is movably inserted into the interior of the mounting column 2 1309. A top block 1311 is fixedly installed on the top of the plug-in column 1310. A grinding disc 1312 is fixedly installed inside the top block 1311. A spring 1313 is fixedly connected between the bottom end of the plug-in column 1310 and the inner bottom surface of the mounting column 2 1309.

[0041] When working, in actual use, first clamp the top plate 6 stably inside the first clamping assembly 5, and then place the pillar 7 inside the second clamping assembly 14 for clamping. After the top plate 6 and the pillar 7 are fixed, the top plate 6 and the pillar 7 can be welded. During welding, first control the electric telescopic rods inside the two opposing extension frames 1302 to drive the clamping block 1303 to move inside the extension frame 1302, that is, drive the mounting plate 1304 to move toward the outside of the pillar 7, and under the action of the mounting seat 1307 and the connecting rod 1308, when the mounting plate 1304 moves toward the outside of the pillar 7, it can drive the mounting plate 2 1306 to move toward the pillar 7 until the outer surface of the grinding disc 1312 contacts the outer surface of the pillar 7, and then the pillar 7 can be limited by the clamping of the two grinding discs 1312, and then control the electric telescopic rod 14 to drive the first clamping assembly 5 to move downward until the bottom surface of the top plate 6 After contacting the top of the pillar 7, it continues to move downward. During the movement, since the pillar 7 is clamped by the two grinding discs 1312, there will be no positional deviation. As the electric telescopic rod 14 moves downward until the bottom surface of the top plate 6 contacts the top surface of the top block 1311, the grinding disc 1312 can contact the connection between the top plate 6 and the pillar 7, that is, the subsequent welding contact. As the electric telescopic rod 14 continues to move downward until the second clamping assembly 14 clamps the pillar 7 again, at this time, the motor is controlled to start, driving the gear 12 to rotate. Since the gear 12 is engaged with the toothed disc 1301, it can drive the toothed disc 1301 to rotate on the outer surface of the top frame 10. During the rotation, the grinding disc 1312 can be used to rotate and grind the welding part of the top plate 6 and the pillar 7, and the temperature of the welding part of the top plate 6 and the pillar 7 is increased, preventing the problem of poor welding effect due to the low temperature of the top plate 6 and the pillar 7 in the subsequent welding operation.

[0042] In the above, the grinding wheel 1312 can be used to effectively grind the welding part of the top plate 6 and the pillar 7, thereby improving the cleanliness of the welding part of the top plate 6 and the pillar 7, and removing rust and other debris on the welding part of the top plate 6 and the pillar 7, thereby improving subsequent welding operations. After cleaning is completed, the electric telescopic rod 3 can be controlled again to drive the clamping block 1303 below the mounting plate 1304 to move toward the pillar 7 until the welding head of the welding machine 1305 above the mounting plate 1304 contacts the welding part of the top plate 6 and the pillar 7, and the top plate 6 and the pillar 7 can be welded. During welding, the toothed disc 1301 is driven to rotate by the motor to realize the welding operation of the top plate 6 and the pillar 7, and the grinding wheel 1312 is away from the pillar 7 during the welding process.

[0043] A first clamping assembly 5 is provided below the electric telescopic rod 4, and the first clamping assembly 5 includes a cross mounting frame 501, which is fixedly connected to the output end of the electric telescopic rod 4. A sliding groove 502 is provided inside the cross mounting frame 501, and positioning plates 503 are fixedly installed at both ends of the top surface of the cross mounting frame 501. Two clamping plates 505 are movably connected inside the sliding groove 502. The electric telescopic rod 2 504 is fixedly connected between one side surface of the two clamping plates 505 and the two positioning plates 503, and the top plate 6 is clamped between the two clamping plates 505.

[0044] During operation, in the process of clamping the top plate 6, the top plate 6 is first placed between the two clamping plates 505, and then the two clamping plates 505 are driven to move toward each other by controlling the electric telescopic rod 2 504 until the two clamping plates 505 clamp the top plate 6. This can achieve fixed clamping of the top plate 6, and the clamping is stable and the operation is simple, which greatly increases the overall practicality and convenience of the device.

[0045] The interior of the main chassis 1 is provided with a second clamping assembly 14, which includes a clamping frame 1401, the clamping frame 1401 is fixedly installed inside the main chassis 1, the internal movable card of the clamping frame 1401 is connected with a movable plate 1402, a limit seat 1403 is installed in the middle of the top surface of the movable plate 1402, the pillar 7 is placed inside the limit seat 1403, both sides of the clamping frame 1401 are provided with a limit groove 1404, the bottom surface of the movable plate 1402 is provided with a spring 2 1410, the interior of the main chassis 1 is provided with two limit grooves 2 1405, the inner parts of the two limit grooves 1405 are provided with a spring 2410. The two ends of the movable plate 1402 are movably connected with a clamping plate 1407, and the other end of the clamping plate 1407 extends to the interior of the clamping frame 1401. One end of the clamping plate 1407 extending to the interior of the clamping frame 1401 is fixedly installed with a clamping plate 2 1406. The bottom surface of the clamping plate 1407 and both sides of the movable plate 1402 are fixedly installed with brackets 1408, and an inclined frame 1409 is connected between the two brackets 1408, wherein the limiting groove 1404 is a T-shaped groove, and the clamping plate 1407 is clamped at the top of the T-shaped groove for limiting. During the downward movement of the movable plate 1402, the clamping plate 1407 does not move downward.

[0046] During operation, when the pillar 7 is placed into the interior of the clamping frame 1401, one end of the pillar 7 is inserted into the interior of the limit seat 1403 to ensure the temporary stability of the pillar 7. After the placement is completed, when the top plate 6 contacts the pillar 7 and moves downward, it can synchronously drive the movable plate 1402 to move downward inside the clamping frame 1401. In the process of the movable plate 1402 moving downward, it can drive the two clamping plates 1407 toward the direction of the pillar 7 under the action of the bracket 1408 and the inclined frame 1409, until the two clamping plates 1406 achieve stable clamping of the pillar 7, and then the pillar 7 can be fixed to prevent shaking during the subsequent cleaning and welding process, so that the pillar 7 is more stable during the welding and cleaning process, thereby achieving the purpose of automatically clamping the pillar 7 when the movable plate 1402 moves downward.

[0047] The bottom surface of the main chassis 1 is provided with an installation cavity 15, and the interior of the main chassis 1 is provided with two rectangular cavities 16. The interiors of the two rectangular cavities 16 are movably connected with sealing card plates 18. The interiors of the two rectangular cavities 16 are both installed with heating wires 17. The bottom surfaces of the sealing card plates 18 are fixedly connected with connecting columns 19. The bottom surface of the movable plate 1402 is fixedly connected with an extension column 1411. One end of the extension column 1411 extends to the interior of the installation cavity 15. The end of the extension column 1411 extending to the interior of the installation cavity 15 is fixedly installed with a bottom plate 1412. The two connecting columns 19 are divided into They are fixedly mounted at both ends of the top surface of the base plate 1412, and mounting blocks 22 are fixedly mounted at both ends of the bottom surface of the cross mounting frame 501. A delivery pipe 20 is installed inside the mounting block 22. One end of the delivery pipe 20 is located inside the rectangular cavity 16, and the other end of the delivery pipe 20 is arranged toward the first clamping assembly 5. In the above, the end of the delivery pipe 20 close to the mounting block 22 is a corrugated hose, that is, half of the part of the delivery pipe 20 located above the main box 1 is a corrugated hose. When the electric telescopic rod 4 drives the top plate 6 to move downward, the delivery pipe 20 is prevented from being affected.

[0048] During operation, when the movable plate 1402 moves downward inside the clamping frame 1401, it can synchronously drive the extension column 1411 to move downward, and in the process of movement, it can drive the bottom plate 1412 and the connecting column 19 to move downward, thereby driving the sealing card plate 18 to move downward inside the rectangular cavity 16, and the outside air is sucked into the interior of the rectangular cavity 16 through the conveying pipe 20, and then heated by the heating wire 17. After the welding is completed, the first clamping component 5 is controlled to lose its clamping on the top plate 6, and moves upward under the drive of the electric telescopic rod 4. At this time, the movable plate 1402 is rotated downward, and the bottom plate 1412 and the connecting column 19 are driven downward. Plate 1402 will move upward under the action of spring 2 1410, thereby driving the sealing card plate 18 to move upward inside the rectangular cavity 16, and discharging the heated air inside the rectangular cavity 16 into the interior of the conveying pipe 20, and finally spraying it to the outside of the pillar 7. The hot air will float upward along the pillar 7 until the welding part between the top plate 6 and the pillar 7, so that the welding part between the top plate 6 and the pillar 7 will not cool down too quickly, and the cooling time will be increased, avoiding the problem of cracks at the welding part due to too fast cooling of the welding part, thereby achieving the purpose of protecting the welding part between the top plate 6 and the pillar 7.

[0049] A box body 23 is fixedly installed inside the installation cavity 15, and an airbag 24 is installed inside the box body 23. An extrusion plate 25 is provided above the airbag 24. The extrusion plate 25 is movably connected to the inside of the box body 23 and is located below the bottom plate 1412. An air outlet pipe 26 is fixedly connected to the surface of one side of the box body 23, and a diverter frame 28 is fixedly installed at one end of the air outlet pipe 26. A connecting pipe 29 is fixedly connected between the diverter frame 28 and the top frame 10, and a plurality of air outlet holes 30 are provided on the inner surface of the top frame 10.

[0050] During operation, when cleaning the welding part between the top plate 6 and the pillar 7, some debris will fall between the top frame 10 and the clamping frame 1401, and in the process of clamping the next pillar 7, that is, when the movable plate 1402 moves downward, it can drive the extrusion plate 25 to move downward inside the box body 23, squeezing the airbag 24. During the extrusion process, the air inside the airbag 24 can be squeezed into the inside of the air outlet pipe 26, and finally enter the inside of the top frame 10 through the diversion frame 28 and the connecting pipe 29, and then sprayed out through the air outlet 30, blowing the debris that fell between the top frame 10 and the clamping frame 1401 toward the middle of the main chassis 1. Since the height of the clamping frame 1401 is higher than the top frame 10, and a storage groove is opened on the outside of the clamping frame 1401, the debris blown toward the middle will be uniformly stored inside the storage groove.

[0051] A method for welding a double-column foot node of an air-cooling tower comprises the following steps:

[0052] S1: Place the top plate 6 between the two clamping plates 505. Then, control the electric telescopic rod 504 to drive the two clamping plates 505 to move toward each other to fix the top plate 6. Then, place the support 7 inside the second clamping assembly 14 to clamp it. After the top plate 6 and the support 7 are fixed, the top plate 6 and the support 7 can be welded.

[0053] S2: By controlling the electric telescopic rods inside the two opposing extension frames 1302, the clamping block 1303 is driven to move inside the extension frame 1302. When the mounting plate 1304 moves toward the outside of the pillar 7, until the outer surface of the grinding disc 1312 contacts the outer surface of the pillar 7, the electric telescopic rod 14 is controlled to drive the first clamping assembly 5 to move downward until the bottom surface of the top plate 6 contacts the top surface of the top block 1311. The grinding disc 1312 can then contact the connection between the top plate 6 and the pillar 7. By controlling the motor to start, the toothed disc 1301 is driven to rotate on the outer surface of the top frame 10, and the welded portion of the top plate 6 and the pillar 7 is rotationally polished, thereby improving the subsequent welding effect.

[0054] S3: By controlling the electric telescopic rod 3 to drive the clamping block 1303 below the mounting plate 1304 to move toward the pillar 7, until the welding head of the welding machine 1305 above the mounting plate 1304 contacts the welding portion of the top plate 6 and the pillar 7, the top plate 6 and the pillar 7 can be welded. During welding, the gear plate 1301 is driven to rotate by controlling the motor to achieve the welding operation of the top plate 6 and the pillar 7;

[0055] S4: During the downward movement of the movable plate 1402, the two clamping plates 1407 can be driven to move toward the pillar 7 under the action of the bracket 1408 and the inclined frame 1409 until the two clamping plates 1406 can stably clamp the pillar 7. Then, the pillar 7 can be fixed to prevent shaking during the subsequent cleaning and welding process, making the pillar 7 more stable during the welding and cleaning process.

[0056] S5: The heated air inside the rectangular cavity 16 is discharged into the inside of the conveying pipe 20 and sprayed into the outside of the pillar 7. The hot air will float upward along the pillar 7 until it reaches the welding part between the top plate 6 and the pillar 7, so that the welding part between the top plate 6 and the pillar 7 will not cool down too quickly, increasing the cooling time and avoiding cracks at the welding part due to excessive cooling of the welding part.

[0057] Specifically, the working process or working principle of the double-column foot node welding mechanism and method of the air-cooling tower is as follows: when in use, the top plate 6 is first stably clamped inside the first clamping assembly 5, and then the pillar 7 is placed inside the second clamping assembly 14 for clamping. After the top plate 6 and the pillar 7 are fixed, the top plate 6 and the pillar 7 can be welded. When welding, first, the electric telescopic rods inside the two opposing extension frames 1302 are controlled to drive the clamping block 1303 to move inside the extension frame 1302, that is, to drive the mounting plate 130 4 moves toward the outside of the pillar 7, and under the action of the mounting seat 1307 and the connecting rod 1308, when the mounting plate 1304 moves toward the outside of the pillar 7, the mounting plate 2 1306 can be driven to move toward the pillar 7 until the outer surface of the grinding disc 1312 contacts the outer surface of the pillar 7, and the pillar 7 can be limited by the clamping of the two grinding discs 1312, and then the first clamping assembly 5 is driven downward by controlling the electric telescopic rod 14 until the bottom surface of the top plate 6 contacts the top end of the pillar 7, and then continues to move downward. During the operation, since the pillar 7 is clamped by the two grinding discs 1312, there will be no positional deviation. As the electric telescopic rod 14 moves downward, until the bottom surface of the top plate 6 contacts the top surface of the top block 1311, the grinding disc 1312 can contact the connection between the top plate 6 and the pillar 7, that is, the subsequent welding contact. As the electric telescopic rod 14 continues to move downward, until the second clamping assembly 14 clamps the pillar 7 again, at this time, the motor is controlled to start, driving the gear 12 to rotate. Since the gear 12 is engaged with the toothed disc 1301, it can drive the gear The disc 1301 rotates on the outer surface of the top frame 10. During the rotation, the grinding disc 1312 can be used to clean the weld between the top plate 6 and the pillar 7. The electric telescopic rod 3 is controlled to drive the clamping block 1303 below the mounting plate 1304 to move toward the pillar 7 until the welding head of the welding machine 1305 above the mounting plate 1304 contacts the weld between the top plate 6 and the pillar 7. Then, the top plate 6 and the pillar 7 can be welded. During welding, the gear disc 1301 is also controlled to rotate to achieve the welding operation of the top plate 6 and the pillar 7.

[0058] When the pillar 7 is placed into the interior of the clamping frame 1401, one end of the pillar 7 is inserted into the interior of the limit seat 1403 to ensure the temporary stability of the pillar 7. After the placement is completed, when the top plate 6 contacts the pillar 7 and moves downward, it can synchronously drive the movable plate 1402 to move downward inside the clamping frame 1401. During the downward movement of the movable plate 1402, the two clamping plates 1407 can be driven to move toward the direction of the pillar 7 under the action of the bracket 1408 and the inclined frame 1409. After the two clamping plates 1406 achieve stable clamping of the pillar 7, the pillar 7 can be fixed to prevent shaking during the subsequent cleaning and welding process.
