Technical Field

[0002] The power tower is a large steel structure facility used to support overhead transmission lines. Its main body is assembled from angle steel, channel steel and other steel materials through welding, bolt connection and other processes. It has extremely strong mechanical strength and can withstand severe natural conditions such as strong winds, icing, earthquakes, etc. It can be divided into straight towers according to its use, which are used to support the straight section of the line; tension towers, which can withstand the tension of the line and play a key role at the corners and terminals of the line; corner towers, which realize the change of line direction; terminal towers, which are built at the starting and end of the transmission line. According to the structural form, there are many types such as wine glass type, cat head type, and dry character type. It is widely used in power systems and is an important infrastructure to ensure the efficient and stable transmission of electric energy from power plants to substations and then distributed to the user end.

The welding slag passes through the gas hood 55 and the nozzle 54 in turn, and contacts the cooling water in the water tank 53 at the trough body 56 to complete the cooling of the welding slag and finally sink into the water tank 53. The welding slag splashing around can also be adsorbed by the gas hood 55 to produce an arc trajectory and finally fall into the water tank 53 to cool the welding slag and avoid contacting the welding molten pool to affect the welding quality.

[0029] The air suction assembly 52 includes a box body 521, which is fixedly connected to the top of the base plate 1. The side of the box body 521 is fixedly connected to the outer side of the water tank 53. The side of the box body 521 away from the base plate 1 is fixedly connected to the ends of several branch pipes 51. A pump body 522 is arranged inside the water tank 53. The end of the pump body 522 close to the box body 521 passes through the water tank 53 and the box body 521, and is fixedly connected to the inner side of the box body 521, and the outer side of the pump body 522 is fixedly connected to the inner side of the water tank 53. The end of the pump body 522 away from the box body 521 is fixedly connected to the main pipe 523. Both ends of the main pipe 523 are fixedly connected to the inner side of the water tank 53. The surface of the main pipe 523 is fixedly connected to one end of several nozzles 54 away from the gas hood 55. When the pump body 522 is started, the pump body 522 drives the gas to pass through the gas hood 55, the nozzle 54, the main pipe 523, the pump body 522, the box body 521, and the branch pipe 51 in sequence, so as to finally collect the welding slag.

[0030] When in use, place the tower foot plate on the frame 331, the magnetic plate 327 adsorbs the tower foot plate, and the bolts are passed through the mounting holes and threaded tubes 332 of the tower foot plate in sequence and tightened. Several threaded tubes 332 fix the tower foot plate, start the rotating telescopic rod 328, and the output end of the rotating telescopic rod 328 feeds or rotates, which eventually drives the frame 331 to move or deflect, and the mounting seat 325 moves. The mounting seat 325 slides inside the driving arm 322, driving the motor 323 and the rotating shaft 324 to move, driving the frame 331 to move, and finally driving the tower foot plate to move, and cooperate with the welder 43 to weld the tower foot plate and the stiffening plate, and the mounting seat 325 moves. 25 rotates, driving the driving arm 322 to rotate, the driving arm 322 slides inside the ring rail 321, and finally drives the tower foot plate to deflect, so that the stiffening plate and the tower foot plate can be welded at all contact positions, the rotating seat 421 drives the driver 422 to rotate, the driver 422 drives the first rotating arm 423 to rotate around the driver 422, and drives the second rotating arm 424 to rotate around the first rotating arm 423, and finally drives the welder 43 to move, so as to realize the welding of different positions of the tower foot plate and the stiffening plate, and drives the rotating rod 426 to rotate inside the rotating cylinder 425, and the rotating rod 426 can deflect at various angles, so as to realize the tower foot plate. The welding at the corner of the foot plate and the stiffening plate is automatic. The air pipe 442 is connected to the protective gas, and the protective gas enters the air cylinder 441 and then sprays out from the air cylinder 441 to form an annular air column. The protective gas moves with the welder 43 to protect the welding position. The air suction component 52 is started, and the air suction component 52 drives the air flow to pass through the air hood 55, the nozzle 54, the air suction component 52, and the branch pipe 51 in sequence. The branch pipe 51 sprays gas upward, and the pressure at the gap between the frame 331 and the driving arm 322 is reduced. The welding slag and smoke move to the side of the frame 331 away from the tower foot plate. The welding slag is heavy and difficult to be sucked by the branch pipe 51. The suction force generated by the air hood 55 can The welding slag can be sucked to the other side. Compared with the adsorption of the branch pipe 51 by changing the pressure, the direct suction of the gas hood 55 has a stronger adsorption force, and can suck the naturally falling welding slag into the gas hood 55. The smoke is pulled by the suction of the branch pipe 51 and the gas hood 55, and the smoke is dispersed and sucked into the gas hood 55. The welding slag passes through the gas hood 55 and the nozzle 54 in turn, and contacts the cooling water in the water tank 53 at the trough body 56 to complete the cooling of the welding slag and finally sink into the water tank 53. The welding slag splashing around can also be adsorbed by the gas hood 55 to produce an arc trajectory, and finally fall into the water tank 53, so as to cool the welding slag and prevent the welding slag from contacting the welding molten pool.
