The vertical plate 6 is fixedly connected to the inner bottom surface of the galvanizing tank 1, and the arc-shaped guide plate 7 is fixedly connected to the edge of the port of the galvanizing tank 1. It should be understood that after the square rectangular tube body 48 is galvanized in the galvanizing tank 1, the single square rectangular tube body 48 is moved into the limiting guide space between the first partition plate 4 and the second partition plate 5, so that the square rectangular tube body 48 is limited. Under the limitation of the two vertical plates 6, one of the four rectangular surfaces of the square rectangular tube body 48 faces upward, which is ready for the lifting alignment assembly to lift the square rectangular tube body 48. During the lifting process of the square rectangular tube body 48, the limiting guide space always limits the square rectangular tube body 48, so that the rectangular surface of the square rectangular tube body 48 can be aligned with the upper traction conveying assembly.

[0042] The lifting alignment assembly comprises a support seat 8 and a turnover driving assembly. The support seat 8 is fixedly installed on the first workbench surface 2.

[0043] The pressing assembly comprises two connecting pins 13 fixedly connected to the surface of the connecting frame 12. A pressing frame 14 is inserted into the surface of the two connecting pins 13. A supporting spring 15 is sleeved on the surface of each of the two connecting pins 13. The two ends of the supporting spring 15 are fixedly connected to the pressing frame 14 and the connecting pin 13, respectively. A pressing rod 16 is fixedly connected to the end of the pressing frame 14. It should be understood that during the turning over process of the turnover frame 10, the connecting frame 12 drives the pressing frame 14 to move synchronously, the pressing frame 14 drives the pressing rod 16 to press the upper end surface of the square rectangular tube body 48, so that the bottom end of the square rectangular tube body 48 is always between the two vertical plates 6, the rectangular surfaces on both sides of the square rectangular tube body 48 are limited, and the square rectangular tube body 48 is prevented from turning over. Therefore, the state that one rectangular surface of the square rectangular tube body 48 always faces upward against the traction conveying assembly is maintained.

[0044] The first partition plate 4 is provided with a first notch 17, the first notch 17 comprises a first accommodating groove 1701 and a second accommodating groove 1702, and the second partition plate 5 is provided with a third accommodating groove 18. It should be understood that the first accommodating groove 1701 provides an accommodating space for the turnover plate 19, and the second accommodating groove 1702 and the third accommodating groove 18 both provide an accommodating space for the lifting rod 11, so that the lifting rod 11 is not limited by the first partition plate 4 and the second partition plate 5.

[0045] The turnover driving assembly comprises the turnover plate 19 and a first cylinder 20, the turnover plate 19 is fixedly connected to the end of the support shaft 9, the cylinder body of the first cylinder 20 is rotationally connected to the first workbench surface 2, and the piston rod end of the first cylinder 20 is rotationally connected to the end of the turnover plate 19. It should be understood that when the turnover plate 19 needs to be driven to turn over, the first cylinder 20 is started, the first cylinder 20 pulls the turnover plate 19, the turnover plate 19 drives the support shaft 9 to rotate, and the support shaft 9 synchronously drives the turnover frame 10 to turn over, thereby realizing turnover driving of the turnover frame 10.

[0046] The traction conveying assembly comprises a plurality of support legs 21, the plurality of support legs 21 are fixedly connected with a conveying frame 22, the conveying frame 22 is obliquely arranged, a plurality of traction magnetic rollers 23 are rotationally connected to the lower inclined surface of the conveying frame 22, the plurality of traction magnetic rollers 23 are all rotationally connected with the conveying frame 22 through connecting shafts 24, the ends of the plurality of connecting shafts 24 are all fixedly installed with synchronous wheels 25, the plurality of synchronous wheels 25 are transmissionally connected through a synchronous belt 26, the plurality of traction magnetic rollers 23 are divided into two groups, the first group of traction magnetic rollers 23 is two and is located at the bottom end of the lower inclined surface of the conveying frame 22, and the second group of traction magnetic rollers 23 is three and is located at the top end of the lower inclined surface of the conveying frame 22. In the process of lifting the square tube body 48 from the limiting guide space, the square tube body 48 will be in contact with the two traction magnetic rollers 23 of the first group, so as to clamp the square tube body 48 between the lifting rod 11 and the two traction magnetic rollers 23 of the first group, and the square tube body 48 is parallel to the traction direction. It should be understood that the traction magnetic roller 23 is a prior art, and the square tube body 48 is a metal tube that can be magnetically attracted, so that the close square tube body 48 can be magnetically attracted. The specific magnetic attraction process is as follows: the lifting rod 11 lifts one end of the square tube body 48 in the limiting guide space, and the square tube body 48 is attached to the two traction magnetic rollers 23 of the first group, so that the lifted square tube body 48 is supported on both sides, and the three-point contact formed by the two traction rollers and the lifting rod 11 clamps the square tube body 48, so that the square tube body 48 always remains parallel to the direction of conveying of the traction magnetic roller 23.

[0047] The traction magnetic roller 23 is usually made of high Curie temperature material, such as FeCr13 alloy, with a Curie temperature of about 480℃, and the outlet temperature of the galvanizing tank 1 is usually 400-500℃. The traction magnetic roller 23 is at a certain distance from the outlet of the galvanizing tank, and the square tube body 48 is lifted out of the galvanizing liquid, and the surface is also cooled by external blowing in space. The temperature of the square tube body 48 contacted by the traction magnetic roller 23 will drop, so the traction magnetic roller 23 can maintain effective magnetic properties.

[0048] The pressing assembly presses the square tube body 48, which increases the support point of the upper end surface of the square tube body 48, and makes one end of the square tube body 48 lift up and the other end sink down during lifting, so that both ends are stressed, and the inclined state of the square tube body 48 is maintained, which is beneficial to the smooth lifting of the square tube body 48 and overcomes the effect of the buoyancy of the galvanizing liquid on the square tube body 48.

It should be understood that during traction conveying, the first motor 27 drives the driving wheel 30 to rotate, the driving wheel 30 drives the follower wheel 31 to rotate through the transmission belt 32, and the follower wheel 31 drives one of the traction magnetic rollers 23 to rotate through the connecting shaft 24. Under the transmission of the synchronous belt 26 and the synchronous wheel 25, all the connecting shafts 24 rotate synchronously in the same direction, thereby driving all the traction magnetic rollers 23 to rotate synchronously, and the square tube body 48 is inclined conveyed.

[0050] The whole traction conveying process is as follows:

[0051] The square tube body 48 is guided and limited: after the square tube body 48 is galvanized in the galvanizing tank 1, the single square tube body 48 is moved to the limiting and guiding space between the first partition plate 4 and the second partition plate 5, so that the square tube body 48 is limited, and under the limitation of the two vertical plates 6, one of the four rectangular surfaces of the square tube body 48 faces upward, which is ready for the lifting of the lifting alignment assembly;

[0052] The other square tube body 48 is lifted: after the square tube body 48 enters the limiting guide space, the turnover driving assembly is started, one end of the square tube body 48 in the limiting guide space is lifted by the lifting rod 11, the square tube body 48 is attached to the first group of two traction magnetic rollers 23, so that the square tube body 48 lifted on both sides is supported, the three-point contact formed by the two traction rollers and the lifting rod 11 clamps the square tube body 48, so that the square tube body 48 always maintains parallel to the direction of the traction magnetic roller 23 conveying, the pressing assembly presses the square tube body 48, so that the upper end surface of the square tube body 48 increases a support point, and the square tube body 48 is lifted in the process, one end of the square tube body 48 is lifted, the other end is pressed to sink, both ends are stressed, so that the inclined state of the square tube body 48 is maintained, which is beneficial to the smooth lifting of the square tube body 48;

[0053] Traction conveying: the first motor 27 drives the driving wheel 30 to rotate, the driving wheel 30 drives the follower wheel 31 to rotate through the transmission belt 32, the follower wheel 31 drives one of the traction magnetic rollers 23 to rotate through the connecting shaft 24, all the connecting shafts 24 are synchronously and synchronously rotated under the transmission of the synchronous belt 26 and the synchronous wheel 25, thereby driving all the traction magnetic rollers 23 to rotate synchronously, the square tube body 48 is inclined conveyed, and the square tube body 48 is kept in parallel to the direction of the traction magnetic roller 23 conveying, thereby providing a stable environment for the external blowing operation.

[0054] As shown in Figure 1 and Figure 8 In one embodiment, a support assembly is arranged between the first group of traction magnetic rollers 23 and the second group of traction magnetic rollers 23, the support assembly includes a mounting frame 33 fixedly connected to the lower inclined surface of the conveying frame 22, and an auxiliary supporting roller 34 is rotatably connected to the mounting frame 33. The square tube body 48 will be placed on the upper surface of the auxiliary supporting roller 34 during the process of passing through the first group of traction magnetic rollers 23 and the second group of traction magnetic rollers 23. It should be understood that the auxiliary supporting roller 34 supports the lower part of the square tube body 48 conveyed by the first group of traction magnetic rollers 23, maintains the stability of the inclined conveying of the square tube body 48, and is beneficial to reducing the magnetic attraction pressure of the traction magnetic roller 23.

[0055] As shown in Figure 1 and Figure 9As shown in the figure, in one embodiment, a limiting guide assembly is arranged between the auxiliary supporting roller 34 and the second set of traction magnetic roller 23, the limiting guide assembly comprises a mounting seat 35 fixedly connected on the lower inclined surface of the conveying frame 22, two guide rollers 36 are rotatably connected at the bottom end of the mounting seat 35, a guide gap is formed between the two guide rollers 36, and the square tube body 48 passing through is limited and guided. It should be understood that during the movement of the square tube body 48 from the auxiliary supporting roller 34 to the two guide rollers 36, the bottom end, both sides and the upper surface of the square tube body 48 are supported, the stable conveying of the square tube body 48 is maintained, and the conditions for stable conveying of the square tube body 48 are provided during the external blowing on the surface of the square tube body 48.

[0056] As shown in the figure, Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown in the figure, in one embodiment, the second workbench surface 3 is also provided with a cleaning assembly, the cleaning assembly comprises a connecting track 37 fixedly connected on the second workbench surface 3, a moving seat 38 is slidably arranged on the connecting track 37, a second motor 39 is fixedly installed on the moving seat 38, the second motor 39 is fixedly connected on the moving seat 38, a connecting rod 40 is fixedly connected on the output end of the second motor 39, the connecting rod 40 is rotatably connected on the moving seat 38, a cleaning plate 4001 is fixedly connected on the surface of the connecting rod 40, a drive screw 42 is threadedly connected at the bottom end of the moving seat 38, the both ends of the drive screw 42 are rotatably connected with a limiting seat 41, the two limiting seats 41 are fixedly connected on both ends of the connecting track 37, the surface of one of the limiting seats 41 is fixedly connected with a third motor 43, and the output shaft of the third motor 43 is fixedly connected with the end of the drive screw 42.

[0057] The surfaces of the two limiting seats 41 are respectively fixedly connected with a first pressure sensor 44 and a second pressure sensor 45, and the surface of the conveying frame 22 is fixedly connected with a frame body 4601, and the frame body 4601 is installed with a camera 46.

[0058] Specifically, Figure 10 is a state diagram of the cleaning assembly during cleaning; Figure 11 is a state diagram of the cleaning assembly after cleaning is completed;

[0059] It should be understood that during the process of lifting the square tube body 48, there will be a dross layer on the surface of the galvanizing liquid. If it is not cleaned in time, the dross will stick to the surface of the square tube body 48 when it is lifted, affecting the quality of galvanizing. The specific solution is as follows: after the camera 46 detects that the square tube body 48 leaves the first group of traction magnetic rollers 23, the camera 46 will send the picture information to the controller 47 for identification. The identification method is: by comparing with the picture information of the square tube body 48 leaving the first group of traction magnetic rollers 23 stored in the fixed memory in the controller 47, the control information of the third motor 43 is generated after successful comparison. The identification and comparison of the image information captured by the camera 46 are prior art, and the controller 47 will control the third motor 43 to start according to the image information of the square tube body 48 leaving the first group of traction magnetic rollers 23 captured by the camera 46. The third motor 43 drives the drive screw 42 to rotate, and the drive screw 42 drives the moving seat 38 to move to the first end of the connecting track 37. At this time, the moving seat 38 will be extruded by the first pressure sensor 44, and the controller 47 will control the second motor 39 to start according to the first pressure information detected by the first pressure sensor 44. The second motor 39 drives the connecting rod 40 to rotate, and the connecting rod 40 drives the cleaning plate 4001 to flip into the upper layer of the galvanizing liquid, so that the cleaning plate 4001 is in a cleaning state, and at the same time, the third motor 43 is controlled to change the direction of driving rotation. The third motor 43 drives the drive screw 42 to change the direction of rotation, and the moving seat 38 drives the cleaning plate 4001 in the pushing state to move through the connecting rod 40, pushes the dross layer on the surface of the galvanizing liquid, and realizes cleaning at the galvanizing liquid surface where the square tube body 48 emerges, preparing for the next square tube body 48 to be lifted.

[0060] When the moving seat 38 drives the cleaning plate 4001 to complete the pushing, the moving seat 38 extrudes the second pressure sensor 45, and the controller 47 controls the third motor 43 to close and the second motor 39 to open according to the second pressure value information detected by the second pressure sensor 45. The second motor 39 drives the connecting rod 40 to rotate, so that the connecting rod 40 drives the flip plate 19 to flip away from the galvanizing liquid, and completes the automatic pushing and cleaning at the galvanizing liquid surface where the square tube body 48 emerges.

[0061] Specifically, the controller 47 obtains information through the camera 46 and the first and second pressure sensors 44 and 45, analyzes the relative position relationship between the internal components of the image information, and analyzes the position state of the moving seat 38 when the pressure sensor is pressed. Both are prior art.

[0062] Specifically, the controller 47 is installed on the conveying frame 22.

[0063] The above merely preferred embodiments of the present application are not used to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
