[0031] Specifically, when the operator sends a start signal through the remote control handle, the motor starts to operate, the rotating motion generated by the motor is transmitted to the speed reducer through the shaft coupling, the speed reducer converts the high-speed rotation of the motor into low-speed high-torque rotation to provide sufficient driving force, and the rotating motion after speed reduction is transmitted to the walking wheel through the transmission shaft to ensure that the walking wheel obtains sufficient rotating force.

[0032] The walking wheel rolls on the track 200 to drive the whole air box bracket 300 and the special air box 400 thereon to move along the track 200, and the walking wheel usually adopts a structure with bearings to reduce friction and ensure smooth operation. The track 200 is laid on the joist 100 to ensure that the walking wheel moves along the predetermined path, and the track 200 is provided with a stopper at both ends to prevent the special air box 400 from exceeding the predetermined range during movement and ensure safety.

[0034] The end of the walking mechanism 210 is connected with the wind box bracket 300 through bolt fastening, and the wind box bracket 300 is welded by H steel, wherein the upper part of the wind box bracket 300 is integrally formed with a supporting plate 310, and the special wind box 400 is fixed and supported by the supporting plate 310, wherein the special wind box 400 is installed on the surface of the supporting plate 310 through bolt fastening.

[0035] The special wind box 400 is arranged above the walking mechanism 210, the special wind box 400 is designed according to the height space of the production line, and the special wind box 400 is welded by steel strips, and the special wind box 400 is pressurized and air supplied by the energy-saving fan 440, and the special wind box 400 adopts a high-efficiency energy-saving frequency conversion fan, which has the characteristics of large air volume, small volume and light weight.

[0036] The input end of the energy-saving fan 440 is connected with the high-temperature-resistant shrinkable air pipe 410 through a flange, wherein the input end of the high-temperature-resistant shrinkable air pipe 410 is connected with the external air inlet, and the high-temperature-resistant shrinkable air pipe 410 is arranged in an extendable form, so that the special wind box 400 can move to take air under the action of the supporting plate 310, and the air outlet ends of the front and rear ends of the special wind box 400 are connected with the air outlet pipes 420, wherein the output end of the air outlet pipe 420 is connected with the air supply pipe 430, and the air supply pipe 430 is used for air supply to the air pipe 610 and the telescopic pipe 700, wherein the air supply pipe 430 is connected with the air pipe 610 and the telescopic pipe 700 in a sealed rotary manner, and the air supply pipe 430 is preferably an extendable hose.

[0037] The front and rear ends of the special wind box 400 are arranged with rotating main shafts 500, and the rotating main shafts 500 are movably installed on the side surface of the special wind box 400 through mounting seats 501, wherein the mounting seats 501 are bolted on the surface of the special wind box 400, and the connecting part of the rotating main shaft 500 and the mounting seat 501 is rotatably connected through a bearing; in this way, the mounting seat 501 and the special wind box 400 are used to support the rotating main shaft 500; the left sides of the two rotating main shafts 500 are respectively connected with a main pushing plate 510 and an auxiliary pushing plate 520, wherein the main pushing plate 510 and the auxiliary pushing plate 520 are made of the same material.

[0038] The rotating main shaft 500 is preferably designed as two, and the two rotating main shafts 500 are used in cooperation with the main pushing plate 510 and the auxiliary pushing plate 520.

[0039] Among them, an air pipe 610 is installed in the output direction of the special bellows 400, and the air pipe 610 can be used to send out the gas in the special bellows 400 to pre-cool the steel strip after galvanizing. Two supports 600 are symmetrically installed along the axis on the outer surface of the air pipe 610, wherein the surface of the support 600 is provided with a mounting groove 601, and the support 600 is movably sleeved on the surface of the air pipe 610 through a bearing. A drive motor 620 is installed on one side of the support 600, and the drive motor 620 is single and is fastened to the surface of the adjacent support 600 by bolts. The output end of the support 600 and the outer surface of the air pipe 610 are both sleeved with a gear part 621, and the two gear parts 621 are meshed with each other, wherein the gear part 621 located on the output shaft of the drive motor 620 is arranged in the inner cavity of the mounting groove 601;

[0040] At the same time, the inner cavity of the mounting slot 601 of the rear support 600 is rotatably connected to a rotating drum, and the outer surface of the air pipe 610 is sleeved with the rotating drum on the rear side and contacts the rear support 600. In this way, the two supports 600 can provide auxiliary support for the air pipe 610. At the same time, under the rotation of the drive motor 620, the drive gear 621 can drive the air pipe 610 to rotate, thereby adjusting the angle of the air nozzle 710 installed on its surface.

[0041] Finally, with the cooperation of the track 200 and the walking mechanism 210, the position of the air pipe 610 and the air nozzle 710 in the telescopic pipe 700 can be adjusted. At the same time, the driving motor 620 and the gear part 621 can be used to adjust the inclination angle of the air nozzle 710 in the air pipe 610.

[0042] A telescopic pipe 700 is provided on one side of the air pipe 610. Two symmetrical sets of telescopic pipes 700 are provided, each consisting of a fixed pipe and a telescopic hose. The two fixed pipes are mounted on the surfaces of the push-joint main plate 510 and the push-joint auxiliary plate 520, respectively. When the telescopic hoses in the telescopic pipes 700 are extended, the opposing sides of the two telescopic pipes 700 engage with each other.

[0043] Specifically, such as Figure 6 As shown, a hanger is installed on one side of the push-connect main plate 510 and the push-connect auxiliary plate 520. After the telescopic pipe 700 is retracted inward, the hanger can be used to fix one end of the telescopic hose;

[0044] As a further optimization of this solution, an auxiliary telescopic frame can be snapped onto the surface of the hanging bracket. After the telescopic hoses in the two telescopic pipes 700 are unfolded, the auxiliary telescopic frame can be used to assist in fixing the telescopic pipes 700.

[0045] The surfaces of the air pipe 610 and the telescopic pipe 700 are provided with a plurality of air nozzles 710. The air nozzles 710 are symmetrically arranged on the surfaces of the air pipe 610 and the telescopic pipe 700. The air pipe 610 and the telescopic pipe 700 are in communication with the inner cavities of the air nozzles 710. The gas sent by the air pipe 430 is finally sprayed out through the air nozzles 710. The zinc-coated steel strip is pre-cooled and cooled under the action of the increased air pressure.

[0046] Further, the air pipe 610 and the telescopic pipe 700 are used in cooperation, so that the two surfaces of the zinc-coated steel strip can be blown and cooled at the same time. The problem that the single air pipe 610 cannot quickly cool the zinc-coated steel strip is avoided.

[0047] The right side of the special wind box 400 is movably connected with a hydraulic cylinder 800 through a rotating shaft. The output end of the hydraulic cylinder 800 is rotatably connected with a convex disc 810. The convex disc 810 is sleeved on the surface of the adjacent rotating main shaft 500. When the hydraulic cylinder 800 works, the convex disc 810 drives the rotating main shaft 500 to rotate, and then drives the push-connection main plate 510 on one side to rotate, so as to drive the telescopic pipe 700 connected thereto to rotate, and change the inclination angle of the telescopic pipe 700.

[0048] The bottom surface of the push-connection main plate 510 is connected with a push-main rod 820. The end surface of the push-connection auxiliary plate 520 is connected with a push-auxiliary rod 830. The opposite sides of the push-main rod 820 and the push-auxiliary rod 830 are movably connected with a connecting guide rod 840 through a rotating shaft. When the rotating main shaft 500 is stressed and drives the adjacent push-connection main plate 510 to rotate, the push-main rod 820 drives the connecting guide rod 840 to drive the push-auxiliary rod 830 to drive the push-connection auxiliary plate 520 to rotate, so as to synchronously drive the two telescopic pipes 700 to move oppositely or reversely. When the two telescopic pipes 700 move oppositely, the two telescopic pipes 700 are in a horizontally opposite state. When the two telescopic pipes 700 move reversely to the top, the telescopic pipe 700 is in a vertical state. At this time, the telescopic pipe 700 is in a non-shielding state of the zinc-coated steel strip. At this time, the walking mechanism 210 can drive the whole wind box cooling device to move.

[0049] Therefore, when the galvanized steel strip is air-cooled and dried in advance, the telescopic pipe 700 is only needed to be adjusted to be in a horizontal state, then moved by the walking mechanism 210, so that the telescopic pipe 700 passes through the galvanized steel strip, then the telescopic pipe 700 is adjusted to be in a horizontal state, so that the telescopic pipe 700 and the air pipe 610 are at both ends of the galvanized steel strip, then the energy-saving fan 440 is controlled, and the air pressurized by the air jet nozzle 710 is discharged to cool the galvanized steel strip, so that the galvanized steel strip is cooled to a suitable temperature and then conveyed to the deflection roller of the cooling tower, thereby avoiding the problem of product quality reduction when the steel strip contacts the deflection roller.

[0050] In summary, the working principle of the movable air outlet angle adjustable air bellow cooling device is as follows: first, the walking mechanism 210 is started to walk on the track 200, the special air bellow 400 and the air bellow bracket 300 are driven to move along the track to a specified position, then the convex disc 810 is rotated by the telescopic action of the hydraulic cylinder 800, the rotating main shaft 500 is further rotated, the synchronous or reverse movement of the push joint main plate 510 and the push joint auxiliary plate 520 is realized, the position and the inclination angle of the telescopic pipe 700 are adjusted, and the air jet nozzle 710 can be accurately aligned with the galvanized steel strip.

[0051] When the galvanized steel strip needs to be cooled, the energy-saving fan 440 is started, the external air is introduced into the special air bellow 400 through the high-temperature-resistant telescopic air pipe 410, the air is pressurized and then conveyed to the air pipe 610 and the telescopic pipe 700 through the air supply pipe 430, and finally sprayed from the air jet nozzle 710 to form a high-pressure air flow to rapidly cool the galvanized steel strip.

[0052] In this process, the angle of the air pipe 610 can be further adjusted by driving the motor 620 to rotate the gear member 621, so that the cooling effect is optimal.

[0053] The above is only a preferred embodiment of the utility model, and is not used for limiting the utility model, and the utility model can be changed and varied for those skilled in the art. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
