[0025] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0026] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0027] like Figure 1-3 As shown, one specific embodiment of a welding pipe online internal blowing device includes a horizontally mounted support frame 1, on which a plurality of transmission wheels 2 are rotatably mounted, and the outer surface of the transmission wheel 2 is formed with a groove 201, and the cross-sectional shape of the groove 201 on the transmission wheel 2 is V-shaped, which is convenient for transmitting the welding pipe, and the plurality of transmission wheels 2 are arranged horizontally in sequence, so that the transmission wheel 2 can transmit the welding pipe horizontally. The transmission wheels 2 are all equipped with pulleys 3 for uniformly driving the transmission wheels 2 to rotate. Specifically, multiple belts can be used to connect the pulleys 3 and connect them to a motor, and the motor drives the plurality of transmission wheels 2 to rotate, and the cut welding pipes are transported to the top of the support frame 1 along the transmission wheels 2.

[0028] The support frame 1 is also provided with a rotating shaft 4 and a turning motor 5 for driving the rotating shaft 4. The rotating shaft 4 extends along the arrangement direction of the plurality of transmission wheels 2. A plurality of flipping grippers 6 are installed at intervals on the rotating shaft 4, and the flipping grippers 6 are arranged alternately with the transmission wheels 2. When the flipping motor 5 drives the rotating shaft 4 to rotate, it drives the flipping grippers 6 to rotate. When the welded pipe reaches the top of the support frame 1, the flipping motor 5 is started to drive the flipping grippers 6 to flip the welded pipe upward. In this specific embodiment, the flipping grippers 6 include three grab bars 601, and the three grab bars 601 are evenly arranged along the circumference to make the flipping efficiency of the welded pipe higher. The end of the grab bar 601 is bent, and the bending direction is toward the rotation direction to prevent the welded pipe from being thrown out from the end of the grab bar 601 due to excessive speed when the grab bar 601 flips the welded pipe upward.

[0029] A rolling table 7 for transporting welded pipes is installed on one side of the support frame 1. An inclined frame 8 is welded on the upper end surface of the rolling table 7. The side of the inclined frame 8 close to the support frame 1 is higher than the side away from the support frame 1. When the welded pipe is flipped up and falls on the inclined frame 8, the welded pipe rolls down from high to low along the inclined frame 8. A stop cylinder 9 is installed on the rolling table 7. The telescopic end of the stop cylinder 9 passes through the inclined frame 8 to intercept the welded pipe. The stop cylinder 9 can be retracted to release the welded pipe to allow it to continue rolling down. Therefore, the welded pipe can be intercepted and released by controlling the extension and shortening of the stop cylinder 9. There are two stop cylinders 9, which correspond to each other horizontally and are respectively installed on both sides of the rolling table 7, so that the welded pipe is in a horizontal state after being stopped by the stop cylinder 9, which is convenient for subsequent blowing and washing. In this specific embodiment, two inner blowing heads 10 are installed above the tilting frame 8. The inner blowing heads 10 are aligned with the welding pipe openings near the telescopic end of the stop cylinder 9. The two inner blowing heads 10 are respectively aligned with the two welding pipe openings closest to the telescopic end of the stop cylinder 9. When the stop cylinder 9 intercepts two welding pipes, the high-pressure water mist of the two inner blowing heads 10 is turned on to spray high-pressure water mist to wash the inner walls of the two welding pipes. Then the stop cylinder 9 retracts to allow the two welding pipes to continue to roll down. Then the stop cylinder 9 continues to extend and repeats the next round of interception. The device for connecting the inner blowing head 10 with high-pressure water mist is a prior art and will not be described in detail here.

[0030] A collection bin 11 for storing welded pipes is installed below the lower side of the tilting frame 8. When the welded pipes that have been purged continue to roll downward, they fall into the collection bin 11 for collection.

[0031] In order to keep the welded pipes neat after being collected in the collection bin 11, an alignment device 12 is installed at the collection bin 11. The alignment device 12 includes a first aligning plate 1201, a second aligning plate 1202, and an aligning cylinder 1203 for driving the second aligning plate 1202. The first aligning plate 1201 is fixed to one end of the welded pipe in the collection bin 11, and the second aligning plate 1202 is located at the other end of the welded pipe in the collection bin 11 and moves toward the welded pipe under the drive of the aligning cylinder 1203. When in use, after the collection bin 11 collects a certain number of welded pipes, the aligning cylinder 1203 pushes the second aligning plate 1202 to push the welded pipes to align on the first aligning plate 1201.

[0032] The action process is as follows:

[0033] The cut welded pipe is transported to the top of the support frame 1 along the conveying wheel 2. When the turning motor 5 drives the rotating shaft 4 to rotate, it drives the turning grip 6 to rotate. When the welded pipe reaches the top of the support frame 1, the turning motor 5 is started to drive the turning grip 6 to turn the welded pipe upward. When the welded pipe is turned upward and falls on the tilting frame 8, the welded pipe rolls down from high to low along the tilting frame 8. The stop cylinder 9 is in an extended state to intercept the welded pipe. After the stop cylinder 9 intercepts two welded pipes, the high-pressure water mist of the two inner blowing heads 10 is turned on to spray high-pressure water mist to blow and clean the inner walls of the two welded pipes. Then the stop cylinder 9 retracts to allow the two welded pipes to continue to roll down. Then the stop cylinder 9 continues to extend and repeats the next round of interception. The cleaned welded pipe rolls down into the collecting bin 11 for collection.
