The upper end of the track C79 is fixedly connected to the embedding platform 711. The embedding platform 711 can be movably assembled in the track B78. The embedding platform 711 can change along the track B78. The side of the embedding platform 711 farther from the core traction unit 73 is fixedly connected to the deformation member C712 in the track B78. The deformation member The other side of C712 is fixedly connected to the inner side of the track B78, and both longitudinal sides of the track C79 are fixedly connected to the track D710.

When the deformation member C712 is in the shortened state, one side of the track C79 is flush with one side of the fastening platform 76.

[0046] Before transportation, the profile transfer module 7 and the operating arm 6 are fixedly connected through the connecting seats 72 on both sides of the track A71, and the external inflator 716 and the core traction unit 73 are connected, and it is ensured that there is no high-pressure air inside the core traction unit 73. All the air inside the profile transfer module 7 is discharged, and the profile transfer module 7 is changed to the starting state so that the locking and transportation of the profile can be performed again.

[0047] Reference Figure 6-Figure 8The core traction unit 73 includes a switch A731 and an inflator 716 mounted on the operating arm 6. The upper end of the switch A731 is connected to the center of the lower end of the track A71. The lower end of the switch A731 is connected to the switch B732. The switch B732 and the inflator 716 are connected via a rubber tube. The core traction unit 73 also includes an outer tube A733. The lower end of the outer tube A733 is connected to the center of the upper end of the track A71. Both longitudinal sides of the switch A731 are connected to the pipe A737. The other side of the pipe A737 is connected to both sides of the lower end of the outer cylinder A733. A rubber platform A734 is movably installed inside the outer cylinder A733. The upper end of the rubber platform A734 is fixedly connected to the variable column A735. The upper end of the variable column A735 passes through the upper end of the outer cylinder A733 and is connected to the variable unit 74. The outer peripheral surface of the variable column A735 is clamped with a deformation part A736. The deformation part A736 is fixedly connected to the upper end of the inner side of the outer cylinder A733 and the upper end of the rubber platform A734 on both sides vertically.

[0048] When the profile is locked and transported, the profile transfer module 7 can be moved onto the profile, and by turning on the inflator 716, high-pressure air can be injected into the switch B732. At this time, the high-pressure air can flow into the switch A731. At this time, by opening the interfaces on both sides of the switch A731 in the longitudinal direction, the high-pressure airflow can be transported to the outer cylinder A733 through the pipe A737. With the inflow of high-pressure airflow, the rubber platform A734 moves upward under the pressure of the airflow, and pulls the variable column A735 to move upward. At this time, the deformable part A736 shortens under pressure, and finally the force is transported to the position of the variable unit 74.

[0049] Reference Figure 7 、 Figure 9 and Figure 10 The variable unit 74 includes a variable plate 741, the lower end of the variable plate 741 is connected to the upper end of the variable column A735 in the middle, and both sides of the lower end of the variable plate 741 in the length direction are fixedly connected to the connecting platform A742, and the side of the connecting platform A742 farther from the variable plate 741 is screwed to the connecting strip A744, and the side of the connecting strip A744 farther from the connecting platform A742 is screwed to the connecting platform B743, and the lower end of the connecting platform B743 is fixedly connected to the variable platform 745. The variable platform 745 can be movably assembled in the embedding interface 75, and the variable platform 745 can be moved along the embedding interface 75. Both longitudinal sides of the variable platform 745 are screwed to the rotating platform 746, and the surface of the rotating platform 746 is in contact with the inner surface of the embedding interface 75. A pair of variable platforms 745 are equipped with deformation rods 747 on the walls facing each other.

[0050] When the adjustable column A735 moves upward, the adjustable piece 741 moves upward, and the span between the adjustable piece 741 and the track A71 increases. The connecting bar A744 rotates toward the center and pulls the connecting platform B743. The pair of adjustable platforms 745 move in the embedding interface 75, approaching each other, pulling the pair of vertical adjustable parts 77 closer to each other, and finally pulling the pair of fastening platforms 76 closer to each other until the fastening platforms 76 are in contact with the side wall of the profile, thus achieving the initial locking of the profile.

[0051] When the locking of the profile is canceled, the air inside the outer cylinder A733 is discharged. At this time, the core traction unit 73 can return to its original position, and the adjustment unit 74 can return to its original position. Then, the pair of adjustment platforms 745 move away from each other, canceling the locking of the profile, and the deformation rod 747 can stick to the side wall of the embedding interface 75, reducing the impact of the adjustment platform 745.

[0052] Reference Figure 6 、 Figure 11 and Figure 12 The vertical adjustment part 77 includes an outer cylinder B771. The upper end of the outer cylinder B771 is connected to the lower end of the adjustment platform 745. The outside of the outer cylinder B771 close to the core traction unit 73 is connected to the pipe B775. The pipe B775 and the switch A731 are connected horizontally. The side of the outer cylinder B771 farther from the core traction unit 73 is connected to the pipe C776. The other side of the pipe C776 is connected to the outer cylinder C714. A rubber platform B772 is movably assembled in the outer cylinder B771. The lower end of the rubber platform B772 is fixedly connected to the adjustment column B773. The lower end of the adjustment column B773 passes through the lower end of the outer cylinder B771 and is connected to the upper end of the fastening platform 76. The outer peripheral surface of the adjustment column B773 is hooped with a deformation part B774. The deformation part B774 is fixedly connected to the lower end of the rubber platform B772 and the lower end inside the outer cylinder B771 on both sides of the vertical axis.

[0053] When locking and transporting profiles with a large vertical span, by opening the interfaces on both sides of the switch A731, high-pressure air can be filled into the outer cylinder B771 through the pipe B775, and the rubber platform B772 is pressed. At this time, the deformable part B774 is shortened, and the moving column B773 is pulled downward, and the fastening platform 76 is driven to move downward. At this time, the fastening platform 76 moves along the side wall of the profile toward the lower end of the profile, locking the lower end of the profile, and can pull the track B78 and the track C79 downward together until the upper end of the track C79 moves to the lower end of the profile, so that the locking and transport of the profile with a large vertical span can be realized.

[0054] By filling gas into the vertical change portion 77, the fastening platform 76 moves downward and moves to a position close to the lower end of the profile, thereby realizing locking and transporting profiles with different vertical spans, reducing the limitations of the profile transport module 7, and ensuring stable locking and transport of the profiles.

[0055] Reference Figure 5 、 Figure 11 、 Figure 13 and Figure 14 The supporting part 713 includes a guide platform A7131, which is movably assembled in the track C79. The guide platform A7131 can be changed along the track C79. The side of the guide platform A7131 farther from the core traction unit 73 is connected to the variable column C715. The lower end of the guide platform A7131 is fixedly connected to the main supporting platform 7132. The supporting part 713 also includes a guide platform B7133, which is movably assembled in the track D710. The guide platform B7133 can move in the track D710. The lower end of the guide platform B7133 is fixedly connected to the side support platform 7134. The side support platform 7134 is close to the core traction unit 73 and is flush with the track C79. The lower end of the main support platform 7132 is fixedly connected to the connecting platform C7135 on both longitudinal sides. The lower end of the side support platform 7134 is fixedly connected to the connecting platform D7136. The connecting platform C7135 and the connecting platform D7136 are rotated via the connecting strip B7137.

[0056] When the track C79 does not fall to the lower end of the profile, the side wall of the profile cooperates to exert a certain pressure on the side wall of the track C79. At this moment, the deformable member C712 shortens, and the engaging platform 711 moves outward and pulls the track C79 outward until one side of the track C79 is level with the other side of the fastening platform 76.

[0057] When the track C79 falls to the lower end of the profile, the deformable member C712 and the traction track C79 return to their original position. At this time, the profile is moved in the middle and some air in the core traction unit 73 can be discharged, so that the span between the pair of fastening platforms 76 becomes larger. At this time, the fastening platforms 76 stop pressing on the side walls of the profile. At this time, the profile moves downward, and the lower end of the profile and the side support platform 7134 are in contact with the upper end of the main support platform 7132, thus supporting the profile.

[0058] The gas input into the outer cylinder B771 can be discharged through the pipe C776 and flow into the outer cylinder C714, and pull the variable column C715 to move toward the side close to the profile. At this time, the guide platform A7131 moves toward the center close to the profile, and pulls the main support platform 7132 to move toward the center of the profile, enhancing the supporting function. When the guide platform A7131 moves toward the center, several connecting strips B7137 open outward, driving the guide platform B7133 to move. At this time, a pair of guide platforms B7133 move outward, and finally pull several side support platforms 7134 to move toward the corners of the profile, thereby achieving stable support for the profile.

[0059] The filled gas activates the outer cylinder C714 and the supporting part 713, allowing them to lock the side walls of the profile. It can then automatically change the locking of the side walls into supporting the lower end, and change the support in the center into supporting the four corners, thereby enhancing the stability of the support and ensuring the stability of the profile during transportation.

[0060] Before transferring the profile, the profile transfer module 7 and the operating arm 6 are fixedly connected via the connecting seats 72 on both sides of the track A71, and the external inflator 716 is connected to the core traction unit 73. It is ensured that there is no pressurized air inside the core traction unit 73. The air inside the profile transfer module 7 is completely exhausted, and the profile transfer module 7 is returned to the initial state so that the profile can be locked and transferred again.

[0061] When locking and transporting the profile, the profile transport module 7 can be moved onto the profile, and by turning on the inflator 716, high-pressure air can be injected into the switch B732. At this time, the high-pressure air can flow into the switch A731. At this time, by opening the interfaces on both longitudinal sides of the switch A731, the high-pressure air flow can be transported to the outer cylinder A733 through the pipe A737. With the inflow of the high-pressure air flow, the rubber platform A734 moves upward under the pressure of the air flow, and pulls the variable column A735 to move upward. At this time, the deformable member A736 shortens under the pressure, and finally transmits the force to the position of the variable unit 74.

[0062] When the adjustable column A735 moves upward, the adjustable piece 741 moves upward, and the span between the adjustable piece 741 and the track A71 increases. The connecting bar A744 rotates toward the center and pulls the connecting platform B743. The pair of adjustable platforms 745 move in the embedding interface 75, approaching each other, pulling the pair of vertical adjustable parts 77 closer to each other, and finally pulling the pair of fastening platforms 76 closer to each other until the fastening platforms 76 are in contact with the side wall of the profile, thus achieving the initial locking of the profile.

[0063] When the locking of the profile is canceled, the air inside the outer cylinder A733 is exhausted. At this time, the core pulling unit 73 and the adjusting unit 74 can return to their original positions. Then, the pair of adjusting platforms 745 move away from each other, canceling the locking of the profile. The deformable rod 747 can abut against the side wall of the insertion port 75, reducing the impact of the adjusting platform 745.

[0064] When locking and transporting a profile with a large vertical span, by opening the interfaces on both sides of the switch A731, high-pressure air can be filled into the outer cylinder B771 through the pipe B775, and the rubber platform B772 can be pressed. At this time, the deformable member B774 is shortened, and the movable column B773 is pulled downward, and the fastening platform 76 is driven downward. At this time, the fastening platform 76 moves along the side wall of the profile toward the lower end of the profile, locking the lower end of the profile, and can also pull the track B78 and the track C79 downward until the upper end of the track C79 moves to the lower end of the profile, so that the profile with a large vertical span can be locked and transported.

[0065] By filling the vertically movable portion 77 with gas, the fastening platform 76 is moved downward to a position close to the lower end of the profile, thereby achieving locking and transporting of profiles with different vertical spans, reducing the limitations of the profile transport module 7, and ensuring stable locking and transport of the profiles;

[0066] When the track C79 falls to the lower end of the profile, the deformable member C712 and the traction track C79 return to their original position. At this time, the profile is moved in the middle and some air in the core traction unit 73 can be discharged, so that the span between the pair of fastening platforms 76 becomes larger. At this time, the fastening platforms 76 stop pressing on the side walls of the profile. At this time, the profile moves downward, and the lower end of the profile and the side support platform 7134 are in contact with the upper end of the main support platform 7132, thus supporting the profile.

[0067] The gas input into the outer cylinder B771 can be discharged through the pipe C776 and flow into the outer cylinder C714, and pull the variable column C715 to move toward the side close to the profile. At this time, the guide platform A7131 moves toward the center close to the profile, and pulls the main support platform 7132 to move toward the center of the profile, enhancing the supporting function. When the guide platform A7131 moves toward the center, several connecting strips B7137 open outward, driving the guide platform B7133 to move. At this time, a pair of guide platforms B7133 move outward, and finally pull several side support platforms 7134 to move toward the corners of the profile, thereby achieving stable support for the profile.
