[0052] After the metal pipe is cleaned by the cleaning machine 2, a large amount of accumulated water is attached to the surface of the metal pipe, in order to improve the drying efficiency, the blow-drying mechanism 4 is used for pre-drying, as shown in Figure 1 and Figure 2 The blow-drying mechanism 4 includes a mounting frame 41, a rodless cylinder 42 and a blow-drying pipe 43, the mounting frame 41 is arranged above the conveying belt 3; the rodless cylinder 42 is a prior art, which moves by using magnetic attraction principle, the rodless cylinder 42 is fixedly arranged on the mounting frame 41, the blow-drying pipe 43 is fixedly arranged on the output end of the rodless cylinder 42, and a gas hole 401 is formed in the side of the blow-drying pipe 43 close to the conveying belt 3; after the end of the blow-drying pipe 43 is communicated with the gas source equipment, the reciprocating movement of the output end of the rodless cylinder 42 can make the gas flow blown out by the gas hole 401 fully cover the hanging basket 5, so that the accumulated water on the surface of the metal pipe in the hanging basket 5 is blown dry, the metal pipe on the conveying belt 3 is first blow-dried and then enters the drying equipment for drying, and the cleaning and drying efficiency of the metal pipe is improved.

[0053] In the process that the hanging basket 5 is moved from the cleaning machine 2 to the conveying belt 3, in order to avoid the interference and collision between the blow-drying mechanism 4 and the hanging basket 5, the relative position between the rodless cylinder 42 and the conveying belt 3 is preferably adjustable; at the same time, by using the relatively adjustable position, the blow-drying pipe 43 can also blow the hanging basket 5 at different positions, so that the adaptability of the blow-drying mechanism 4 is improved.

[0055] The cleaning machine 2 and conveyor belt 3 are laid out in a straight line on the ground, the water blowing mechanism 4 is fixed to the wall, and the movable frame 6 is fixed to the roof to allow the movable frame 6 to move the basket 5. Figure 3 As shown, the mobile lifting frame 6 includes a second linear module 61, a second telescopic cylinder 62, and a lifting claw 63. The second linear module 61 is positioned above the mobile trolley 1, the washing machine 2, and the conveyor belt 3.

The second telescopic cylinder 62 is fixedly mounted on the output end of the second linear module 61, and its output direction is perpendicular to the horizontal plane. The lifting claw 63 is fixedly mounted on the output end of the second telescopic cylinder 62. When transferring the basket 5, the second telescopic cylinder 62 is used to drive the lifting claw 63 to descend, allowing the lifting claw 63 to engage with the basket 5. Then, the second telescopic cylinder 62 is used to drive the lifting claw 63 to rise, and the second linear module 61 is used to move the basket 5 horizontally. When the basket 5 moves to the position of the next process, the second telescopic cylinder 62 is used to drive the lifting claw 63 to descend, separating the basket 5 from the lifting claw 63.

[0056] like Figure 3 As shown, the suspended basket 5 includes a net basket 51 and multiple lifting rings 52. The lifting rings 52 are fixedly mounted on the net basket 51, and the multiple lifting rings 52 are arranged in a rectangular manner. The lifting claw 63 includes a support plate 631 and multiple hooks 632. The support plate 631 is fixedly mounted on the output end of the second telescopic cylinder 62, and the hooks 632 are fixedly mounted on the support plate 631.

The slide 612 is slidably mounted on the frame 611, and the lead screw 613 is rotatably mounted on the frame 611 and connected to the slide 612 via a threaded engagement. The motor 614 is fixedly mounted on the frame 611, with its output end coaxially fixed with the lead screw 613. The motor 614 can drive the lead screw 613 to rotate, thereby using the threaded engagement between the lead screw 613 and the slide 612, as well as the sliding engagement between the slide 612 and the frame 611, to drive the slide 612 to reciprocate, thus achieving linear drive of the second telescopic cylinder 62.

After the mobile trolley 1 completely enters the positioning frame 71 through the inlet and outlet 701, the mobile trolley 1 abuts against the inner wall of the positioning frame 71, so that the mobile trolley 1 is clamped in the positioning frame 71. When the metal pipe needs to be transferred, the mobile trolley 1 can be pushed out of the inlet and outlet 701 to the outside of the positioning frame 71.

[0060] The guide plates 72 are used for guiding the mobile trolley 1. The guide plates 72 are fixedly arranged on the positioning frame 71. The two guide plates 72 are oppositely arranged on the two sides of the inlet and outlet 701. The distance between the two guide plates 72 gradually increases from the end close to the positioning frame 71 to the end away from the positioning frame 71. The two guide plates 72 are in an eight-character shape. The arrangement of the two guide plates 72 makes the mobile trolley 1 more easily pushed into the positioning frame 71, so as to improve the moving efficiency of the mobile trolley 1.

[0062] The rinsing box 22 comprises a box body 221 and two partitions 222. The partitions 222 are fixedly arranged in the box body 221. The two partitions 222 are parallel and spaced apart. The top ends of the two partitions 222 and the top end of the box body 221 are not flush with each other. As shown in Figure 5 The two partitions 222 divide the rinsing box 22 into three water tanks. The liquid level in the three water tanks decreases from left to right. The impurities on the inner surface of the right water tank will not flow into the left water tank, so that the metal pipe can be sequentially rinsed from right to left, thereby improving the cleaning quality of the metal pipe.

[0063] As shown in Figure 6As shown, the water blowing pipe 43 comprises three air pipes 431, springs 432 and linkage rods 433, the three air pipes 431 are arranged in parallel and are spaced apart, a plurality of air holes 401 are formed on each air pipe 431, the air pipe 431 located in the middle position is fixedly connected with the output end of the rodless air cylinder 42, the springs 432 are respectively arranged between the adjacent two air pipes 431, the linkage rods 433 are respectively arranged in rotation between the adjacent two air pipes 431, two linkage rods 433 are arranged between the adjacent two air pipes 431, and the two linkage rods 433 arranged between the adjacent two air pipes 431 are arranged in parallel and are spaced apart; as shown in Figure 7 and Figure 8 As shown, when the rodless air cylinder 42 drives the water blowing pipe 43 to move to the end position of the rodless air cylinder 42, the air pipes 431 located at the two side positions can abut against the mounting frame 41 or the rodless air cylinder 42, which can cause the linkage rods 433 and the springs 432 to be inclined, so that the air pipes 431 located at the two side positions can move along the axial direction thereof, so as to expand the radiation range of the air pipes 431 and improve the radiation area of the water blowing pipe 43; as shown in Figure 8 As shown, in order to ensure that the air pipes 431 located at the end positions can move in the specified direction, a wedge-shaped sliding block can be arranged on the corresponding air pipe 431, and the sliding block is first abutted against the mounting frame 41 or the rodless air cylinder 42.
