When the limit blocks 22 completely pass through the through hole 21, the rebound force generated by the compression of the first spring 24 will drive the two limit blocks 22 to move outward, so that they slide out of the fixing rod 20, and the other side of the limit block 22 is provided with a contact with the second vertical plate 19, and the resistance generated will limit the movement of the right ring 17 relative to the left ring 16, so that the fixing ring 4 is sleeved on the outside of different thermal pipes 2, providing a bracket for the welding mechanism to rotate around the thermal pipe 2, realizing the welding of the connection between adjacent thermal pipes 2, and at the same time, there is no need to rotate multiple nuts to realize the connection between the left ring 16 and the right ring 17, thereby improving safety. The efficiency of installing the fixing ring 4 is improved, thereby improving the laying efficiency of the large-drop thermal pipeline 2; a contact block 25 is slidably connected to the second vertical plate 19, and a first protrusion 26 is symmetrically provided on one side of the contact block 25, and a second inclined surface 27 in contact with the first inclined surface 23 is provided at the end of the first protrusion 26, and a second protrusion 28 in contact with the end of the fixing rod 20 is provided on one side of the contact block 25, and a first guide rod 29 extending to the outside and in sliding contact with the second vertical plate 19 is provided on the other side of the contact block 25, and a tension spring 30 is sleeved on the outside of the first guide rod 29, and the two ends of the tension spring 30 are respectively connected to the second vertical plate 19 and the contact block 25. After welding is completed, it is only necessary to press the first guide rod extending to the outside of the contact block 25 29, driving the contact block 25 to slide on the second vertical plate 19 until the second inclined surfaces 27 provided on the two first protrusions 26 are respectively in contact with the first inclined surfaces 23 provided on the end of the limit block 22, and the generated component force drives the limit block 22 to move inward until the limit block 22 completely enters the fixing rod 20, and then the second protrusion 28 provided on the end of the contact block 25 contacts the fixing rod 20, and the generated component force drives the fixing rod 20 to slide on the second vertical plate 19, thereby releasing the connection between the ends of the left ring 16 and the right ring 17, and removing the fixing ring 4 from the thermal pipe 2. At the same time, there is no need to rotate multiple nuts to release the connection between the left ring 16 and the right ring 17, thereby improving the efficiency of removing the fixing ring 4, and then improving the laying efficiency of the large-drop thermal pipe 2.

[0037] Preferably, Figure 3 and Figure 4 As shown, one end of the support rod 5 is rotatably connected to an arc plate 31, and the arc plate 31 is provided with a plurality of friction blocks 32 in contact with the thermal pipe 2. Specifically, the friction blocks 32 can be elastic to ensure that multiple friction blocks 32 are in contact with thermal pipes 2 with different outer diameters at the same time, thereby increasing the friction between the support rod 5 and the thermal pipe 2, limiting the axial movement of the fixing ring 4 on the thermal pipe 2, and further improving the stability of the fixing ring 4 during the welding process, thereby improving the welding quality at the connection of the thermal pipe 2 with a large drop; the other end of the support rod 5 is provided with a first guide column 33, and the left ring 16 and the right ring 17 are respectively rotatably connected to the first arc disk 34 and the second arc disk 35, and the first arc disk 34 and the second arc disk 35 are respectively provided with a plurality of inclined grooves 36 in sliding contact with the first guide column 33. After the left ring 16 and the right ring 17 are connected, the first arc disk 34 and the second arc disk 35 are The first arc disk 34 and the second arc disk 35 together form a driving disk, and rotate on the fixing ring 4. By rotating the driving disk on the fixing ring 4, the first arc disk 34 and the second arc disk 35 are driven to rotate on the left ring 16 and the right ring 17 at the same time, and the first arc disk 34 and the second arc disk 35 are respectively provided with a plurality of inclined grooves 36 and the corresponding first guide pillars 33. The component force generated drives the plurality of support rods 5 to slide on the fixing ring 4 at the same time until the arc plates 31 provided at the ends thereof contact the thermal pipe 2 in turn, and support the fixing ring 4 on the outside of the thermal pipe 2. At the same time, the friction force generated after the friction block 32 contacts the thermal pipe 2 limits the axial movement of the fixing ring 4 on the thermal pipe 2, thereby improving the stability of the fixing ring 4 during the welding process. At the same time, there is no need to separately set up a power device to drive the plurality of support rods 5 to move, thereby reducing the space required for the installation of the power device and the manufacturing cost.

[0038] Preferably, Figure 6As shown, the left ring 16 and the right ring 17 are both provided with an annular groove 37 and a convex ring 38, and an annular rack 39 is provided on one side of the convex ring 38. The movable seat 6 is rotatably connected with a first rotating shaft 40 and a second rotating shaft 41, respectively. The first rotating shaft 40 and the second rotating shaft 41 are respectively provided with a second roller 42 and a third roller 43 that are in rolling contact with the annular groove 37 and the convex ring 38, and the third roller 43 is provided with a driving gear 44 that meshes with the annular rack 39; by rotating the second rotating shaft 41 on the movable seat 6, the second rotating shaft 41 is driven The driving gear 44 provided rotates together. Since the driving gear 44 and the annular rack 39 are meshed with each other, the torque generated after the contact is transmitted to the movable seat 6 through the driving gear 44 and the second rotating shaft 41, driving the movable seat 6 to move on the fixed ring 4. At the same time, the second roller 42 and the third roller 43 are in rolling contact with the annular groove 37 and the convex ring 38 at the same time, which plays a guiding role for the movable seat 6 to move on the fixed ring 4, preventing the movable seat 6 from deviating from the specified track, thereby improving the stability of the overall structure and improving the quality of laying the large drop thermal pipeline 2;

[0039] The movable seat 6 is slidably connected with a plurality of driving rods 45, one side of the first arc-shaped disk 34 and the second arc-shaped disk 35 are provided with a plurality of driven rods 46, the end of the driven rod 46 is provided with a plurality of third inclined surfaces 47, the end of the driving rod 45 is provided with a fourth inclined surface 48 in contact with the third inclined surface 47, both sides of the driving rod 45 are provided with L-shaped blocks 49 connected with the movable seat 6, the middle part of the driving rod 45 is provided with a protrusion 50 slidably connected with the L-shaped block 49, and a second spring 51 is provided between the protrusion 50 and the L-shaped block 49. When the movable seat 6 moves on the fixing ring 4, the driving rod 45 is used to move the movable seat 6. The fourth inclined surface 48 provided at the end contacts with the third inclined surface 47 provided at the end of one of the driven rods 46, and the component force generated drives the first arc disk 34 and the second arc disk 35 to move along with the movable seat 6, until the arc plates 31 provided at the ends of the plurality of support rods 5 contact with the thermal pipe 2 at the same time, fixing the fixing ring 4 on the thermal pipe 2. In addition, there is no need to separately provide a power device to drive the movable seat 6, the first arc disk 34 and the second arc disk 35 to rotate on the fixing ring 4, thereby reducing the space required for the installation of the power device and the manufacturing cost. Then, when the movable seat 6 is further driven to move on the fixing ring 4, due to the arc plate 31 contacting the thermal pipe 2, the fixing ring 4 is fixed to the thermal pipe 2. The resistance generated after the contact of the force pipeline 2 will limit the rotation of the first arc disk 34 and the second arc disk 35 relative to the fixed ring 4. When the fourth inclined surface 48 provided at the end of the driving rod 45 contacts the third inclined surface 47 provided at the end of the driven rod 46 again, the component force generated will drive the driving rod 45 to slide on the movable seat 6 and compress the second spring 51 provided between the protrusion 50 and the L-shaped block 49 until the driving rod 45 passes through the corresponding transmission rod. Then, under the action of the rebound force generated by the compression of the second spring 51, the driving rod 45 is driven to reset. The above steps are repeated several times, so that the movable seat 6 can rotate relative to the first arc disk 34 and the second arc disk 35.

At the same time, whenever the driving rod 45 passes through a driven rod 46, the component force generated after the third inclined surface 47 contacts the fourth inclined surface 48 will act on the first arc disk 34 and the second arc disk 35, offsetting the external force applied to the first arc disk 34 and the second arc disk 35 in the opposite direction, preventing the first arc disk 34 and the second arc disk 35 from rotating during the welding process, affecting the fixation of the fixing ring 4 on the thermal pipe 2, thereby ensuring the stability of the overall structure during the welding process and further improving the efficiency of welding the thermal pipe 2 with a large drop.

The resistance generated by the contact between the arc block 57 and the arc groove 54 will limit the rotation of the driven wheel 52 on the movable seat 6, so that the movable seat 6 pauses on the fixed ring 4 for a while, and repeats the above steps many times, and the gap drives the welding mechanism to move around the thermal pipe 2, and cooperates with the slide bar 14 to drive the second slide plate 9 to swing back and forth on the first slide plate 8, driving the welding head to swing together, so that the welding gun 11 leaves a Z-shaped weld at the connection between the two thermal pipes 2, increasing the length and tortuosity of the weld, and better compensating for the larger gap at the connection between adjacent thermal pipes 2, thereby further improving the accuracy of welding the large-drop thermal pipe 2, and then improving the quality of laying the large-drop thermal pipe 2.

The second screw is driven to rotate by the stepping motor to drive the third slide plate 10 to move on the second slide plate 9, and further drive the swing arm 69 and the welding gun 11 on the third slide plate 10 to move downward. At the same time, the resistance generated by the first roller 13 provided at the end of the support rod 12 contacting with the thermal pipeline 2 will limit the support rod 12 from following the movement of the third slide plate 10, so that the support rod 12 moves relative to the swing arm 69, and contacts with the slide groove 70 through the third guide column 71 provided on the support rod 12, and the component force generated drives the swing arm 69 on the third slide plate 10 rotates, and drives the welding gun 11 on the swing arm 69 to rotate together, until the angle between the welding gun 11 and the surface of the thermal pipe 2 is 70°-80°, so as to better control the welding molten pool, evenly distribute the solder, reduce welding defects such as pores and undercuts, and thus improve the quality of laying the thermal pipe 2 with a large drop. In addition, the subsequent downward movement of the welding gun 11 can prevent the welding head from colliding with the thermal pipe 2. At the same time, there is no need to set up a power device to move down and rotate the welding gun 11, further reducing the space required for the installation of the power device and the manufacturing cost; the slide 70 is respectively provided with a fixed block 72 and a slider 73 contacting the third guide column 71, and the fixed block 72 and the slider 73 are respectively in contact with the third guide column 71 to limit the downward movement distance and the swing angle of the welding head, so as to avoid interference between the welding head and the thermal pipe 2 caused by a stepper motor failure, thereby affecting the efficiency and quality of laying the thermal pipe 2 with a large drop.

A transverse rod 82 that is in sliding contact with the third vertical groove 81 is provided on the limit rod 75, and a fourth spring 83 is provided between the torsion block 76 and the slider 73. The rotation of the torsion block 76 by pressing down causes the torsion block 76 to move from the first vertical slot 77 to the transverse slot 79, and then the applied force is cancelled. The spring force generated by the compression of the fourth spring 83 will drive the torsion block 76 to move from the transverse support to the second vertical slot 78, thereby realizing the rotation of the torsion block 76 on the slider 73. At the same time, since the transverse bar 82 provided on the limit rod 75 contacts the third vertical slot 81 provided on the fourth rotating shaft 80, the limit rod 75 will be driven to rotate on the slider 73 together, so that the two sides of the limit rod 75 slide out of the limit slot 74, and the restriction on the sliding of the slider 73 in the slide slot 70 is released. Then the slider 73 is slid on the swing rod 56 to adjust the range of the swing angle of the welding head to avoid interference between the welding head and the thermal pipe 2 caused by a stepper motor failure, thereby improving the efficiency and quality of laying the thermal pipe 2 with a large drop.

[0046] Example 1

[0047] The present invention provides a large drop thermal pipeline laying device, such as Figure 1-Figure 5As shown, when it is necessary to weld the connection between adjacent thermal pipes 2, firstly, two fixing rings 4 are respectively sleeved on the outer sides of the corresponding thermal pipes 2, and a plurality of support rods 5 are radially slid on the fixing rings 4 at the same time, so that the ends of the plurality of support rods 5 are in contact with the thermal pipes 2, ensuring that the forces exerted by the support rods 5 on the thermal pipes 2 are equal, so that the fixing rings 4 and the thermal pipes 2 are in a concentric state, thereby fixing the welding mechanism on the two adjacent thermal pipes 2, and sliding between the movable seats 6 through the connecting plate 7 until the first roller 13 provided at the end of the support rod 12 is in contact with the thermal pipe 2, so as to realize the preliminary positioning of the welding mechanism on the thermal pipe 2, which is convenient for the subsequent welding of the thermal pipes 2 with a large drop, and improves the efficiency of laying the thermal pipes 2 with a large drop;

[0048] Then, the first slide plate 8 is moved transversely on the connecting plate 7 to adjust the transverse position of the welding gun 11 on the thermal pipe 2, and the third slide plate 10 is moved longitudinally on the second slide plate 9 to adjust the longitudinal position of the welding gun 11 on the thermal pipe 2, so that the welding head of the welding gun 11 corresponds to the connection between adjacent thermal pipes 2, thereby achieving accurate positioning of the welding mechanism on thermal pipes 2 with different outer diameters, improving the accuracy of welding thermal pipes 2 with different outer diameters and large drop, improving the sealing of the connection between adjacent thermal pipes 2, and thus improving the quality of laying thermal pipes 2 with different outer diameters and large drop;

[0049] Finally, the two movable seats 6 rotate one or two circles on the fixed ring 4, driving the welding mechanism to rotate one or two circles around the thermal pipe 2, so as to achieve welding at the connection of adjacent thermal pipes 2, and workers do not need to stay on the slope 1 for a long time to weld the thermal pipes 2, further improving the laying efficiency of the thermal pipes 2 with a large drop, while reducing safety hazards during the construction process;

[0050] In addition, during the welding process, the first roller 13 contacts the thermal pipe 2, which will drive the welding head to move slightly, so as to achieve fine-tuning of the welding gun 11 during the movement, and ensure that the distance between the welding head and the connection between the adjacent thermal pipes 2 is always consistent during the welding process, thereby further improving the accuracy of welding the thermal pipes 2 with large drop; in addition, the second slide plate 9 is driven to swing back and forth on the first slide plate 8 by the slide rod 14, and drives the welding gun 11 to swing with it, and cooperates with the driving wheel 15 to drive the movable seat 6 to rotate in the gap on the fixed ring 4, so that the welding gun 11 leaves a Z-shaped weld at the connection between the two thermal pipes 2, increases the length and tortuosity of the weld, and better compensates for the larger gap at the connection between the adjacent thermal pipes 2, thereby further improving the accuracy of welding the thermal pipes 2 with large drop, and then improving the quality of laying the thermal pipes 2 with large drop.

[0051] Example 2

[0052] On the basis of Example 1, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the left ring 16 and the right ring 17 are respectively placed on both sides of the insulation side of the thermal pipe 2, and the first vertical plate 18 and the second vertical plate 19 provided on the left ring 16 and the right ring 17 are made to correspond to each other. Then, the fixing rod 20 on the first vertical plate 18 is slid to pass through the through hole 21 provided on the second vertical plate 19, and at the same time, the first inclined surface 23 provided on one side of the limit block 22 contacts the through hole 21, and the component force generated drives the two limit blocks 22 to move inward, so that the limit blocks 22 pass through the through hole 21 smoothly. When the limit block 22 completely passes through the through hole 21, the first spring 24 is compressed and produces The generated resilience will drive the two limit blocks 22 to move outward, so that they slide out of the fixing rod 20, and the other side of the limit block 22 is provided with a second vertical plate 19 in contact, and the generated resistance will limit the right ring 17 from moving relative to the left ring 16, so that the fixing ring 4 is sleeved on the outside of different thermal pipes 2, providing a bracket for the welding mechanism to rotate around the thermal pipe 2, and realizing the welding of the connection between adjacent thermal pipes 2. At the same time, there is no need to rotate multiple nuts to realize the connection between the left ring 16 and the right ring 17, thereby improving the efficiency of installing the fixing ring 4, and then improving the efficiency of laying the thermal pipe 2 with a large drop;

[0053] After welding is completed, when the fixing ring 4 needs to be removed from the thermal pipe 2, it is only necessary to press the first guide rod 29 extending to the outside of the contact block 25 to drive the contact block 25 to slide on the second vertical plate 19 until the second inclined surfaces 27 provided on the two first protrusions 26 are respectively in contact with the first inclined surfaces 23 provided on the end of the limit block 22, and the generated component force drives the limit block 22 to move inward until the limit block 22 completely enters the fixing rod 20, and then the second protrusion 28 provided on the end of the contact block 25 contacts the fixing rod 20, and the generated component force drives the fixing rod 20 to slide on the second vertical plate 19, thereby releasing the connection between the ends of the left ring 16 and the right ring 17, and removing the fixing ring 4 from the thermal pipe 2. At the same time, there is no need to rotate multiple nuts to release the connection between the left ring 16 and the right ring 17, thereby improving the efficiency of removing the fixing ring 4, and then improving the efficiency of laying the large-drop thermal pipe 2.

[0054] Example 3

[0055] On the basis of Example 2, Figure 3 , Figure 4 and Figure 5As shown, after the left ring 16 and the right ring 17 are connected, the first arc disk 34 and the second arc disk 35 together form a driving disk, and the second rotating shaft 41 is rotated on the movable seat 6 to drive the driving gear 44 provided on the second rotating shaft 41 to rotate together. Since the driving gear 44 and the annular rack 39 are meshed with each other, the torque generated after the contact is transmitted to the movable seat 6 through the driving gear 44 and the second rotating shaft 41, driving the movable seat 6 to move on the fixed ring 4. At the same time, the second roller 42 and the third roller 43 are in rolling contact with the annular groove 37 and the convex ring 38 at the same time, which plays a guiding role for the movable seat 6 to move on the fixed ring 4, and prevents the movable seat 6 from deviating from the specified track, thereby improving the stability of the overall structure and improving the quality of laying the large drop thermal pipeline 2;

[0056] During the movement of the movable seat 6 on the fixed ring 4, the fourth inclined surface 48 provided at the end of the driving rod 45 contacts the third inclined surface 47 provided at the end of one of the driven rods 46, and the component force generated drives the first arc disk 34 and the second arc disk 35 to move together with the movable seat 6, and contacts the corresponding first guide pillars 33 through the several inclined grooves 36 provided on the first arc disk 34 and the second arc disk 35, and the component force generated drives the several support rods 5 to slide on the fixed ring 4 at the same time, until the arc plates 31 provided at the ends of the several support rods 5 contact the thermal pipe 2 at the same time. At the same time, since the friction block 32 is elastic, it is ensured that multiple friction blocks 32 are in contact with the thermal pipes 2 of different outer diameters at the same time, the friction between the support rod 5 and the thermal pipe 2 is increased, and the axial movement of the fixing ring 4 on the thermal pipe 2 is further restricted, and the stability of the fixing ring 4 during the welding process is improved, thereby improving the welding quality of the connection of the thermal pipe 2 with a large drop. The fixing ring 4 is fixed on the thermal pipe 2. In addition, there is no need to separately set a power device to drive the movable seat 6, the first arc disk 34 and the second arc disk 35 to rotate on the fixing ring 4, thereby reducing the space required for the installation of the power device and the manufacturing cost;

[0057] Then, when the movable seat 6 is further driven to move on the fixed ring 4, the resistance generated by the contact between the arc plate 31 and the thermal pipe 2 will limit the rotation of the first arc disk 34 and the second arc disk 35 relative to the fixed ring 4. When the fourth inclined surface 48 provided at the end of the driving rod 45 contacts the third inclined surface 47 provided at the end of the driven rod 46 again, the component force generated will drive the driving rod 45 to slide on the movable seat 6 and compress the second spring 51 provided between the protrusion 50 and the L-shaped block 49 until the driving rod 45 passes through the corresponding transmission rod. Then, under the action of the rebound force generated by the compression of the second spring 51, the driving rod 45 is driven to reset. The above steps are repeated multiple times, so that the movable seat 6 can be moved relative to the first arc disk 34 and the second arc disk 35. The first arc disk 34 and the second arc disk 35 rotate, driving the welding mechanism provided between the two movable seats 6 to move around the thermal pipe 2, thereby realizing the welding of the connection of the thermal pipe 2 with a large drop. At the same time, whenever the driving rod 45 passes through a driven rod 46, the component force generated after the third inclined surface 47 contacts the fourth inclined surface 48 will act on the first arc disk 34 and the second arc disk 35, offsetting the external force applied to the first arc disk 34 and the second arc disk 35 in the opposite direction, preventing the first arc disk 34 and the second arc disk 35 from rotating during the welding process, affecting the fixation of the fixing ring 4 on the thermal pipe 2, thereby ensuring the stability of the overall structure during the welding process, and further improving the efficiency of welding the thermal pipe 2 with a large drop.

[0058] Example 4

[0059] On the basis of Example 1, Figure 8 and Fig. 9 As shown, the driving wheel 15 is driven to rotate by the rotating motor 55, so that the arc block 57 provided on one side of the driving wheel 15 slides out from the arc groove 54, releasing the restriction on the rotation of the driven wheel 52 on the movable seat 6, and then the side of the swing rod 56 contacts the second guide column 53, and the component force generated drives the driven wheel 52 to rotate on the movable seat 6, thereby driving the movable seat 6 to rotate a small end distance on the fixed ring 4, and then the arc block 57 provided on one side of the driving wheel 15 enters the arc groove 54 again, and the resistance generated by the contact between the arc block 57 and the arc groove 54 will limit the rotation of the driven wheel 52 on the movable seat 6, so that the movable seat 6 pauses on the fixed ring 4 for a while, and the above steps are repeated multiple times, and the gap drives the welding mechanism to move around the thermal pipeline 2;

[0060] At the same time, the slide bar 14 is driven to slide on the first slide bar 8 by the telescopic cylinder 66, and the driving rack 68 provided on one side of the slide bar 14 is driven to move together. Since the driving rack 68 is meshed with the driven gear 65 provided on the third rotating shaft 64, the second slide bar 9 rotates around the third rotating shaft 64, and the slide bar 14 is continuously driven to move back and forth by the telescopic cylinder 66, and the second slide bar 9 is driven to swing back and forth on the first slide bar 8, so that by adjusting the telescopic cycle of the telescopic cylinder 66 and the rotation frequency of the rotating motor 55, the welding gun 11 leaves a Z-shaped weld at the connection of the two thermal pipes 2, increasing the length and tortuosity of the weld, and better compensating for the larger gap at the connection of the adjacent thermal pipes 2, thereby further improving the accuracy of welding the thermal pipes 2 with a large drop, and then improving the quality of laying the thermal pipes 2 with a large drop;

[0061] In addition, by adjusting the position of the in-position sensor on the telescopic cylinder 66 and adjusting the extension and retraction position of the telescopic cylinder 66, the swing amplitude of the welding gun 11 is changed, and the width of the Z-shaped weld is adjusted to meet the needs of thermal pipes 2 of different thicknesses and improve the quality of welding different thermal pipes 2.

[0062] Example 5

[0063] On the basis of Example 1, Figure 8 and Fig. 9 As shown, after the fixing ring 4 is fixed on the thermal pipe 2, the resilience generated by the compression of the third spring 63 is transmitted to the first screw 60 through the first nut 61, thereby driving the connecting plate 7 to slide on the mounting seat 85 until the first roller 13 contacts the thermal pipe 2, thereby achieving the initial positioning of the welding mechanism, facilitating the subsequent welding of the connection of the thermal pipe 2, and improving the quality of the welding of the thermal pipe 2 with a large drop;

[0064] When the outer diameter of the thermal pipe 2 changes, the first nut 61 and the second nut 62 are rotated on the first screw 60 to adjust the active range of the second cross plate 59 on the first screw 60 to ensure that when the first roller 13 contacts different thermal pipes 2, the compression amount of the third spring 63 is always maintained in a normal range, so as to avoid the third spring 63 being damaged due to excessive compression, or preventing the third spring 63 from being uncompressed and unable to provide normal rebound force, so as to ensure that during the welding process, the rebound force generated by the compression of the third spring 63 always drives the connecting plate 7 to slide on the movable seat 6 normally, so that the first roller 13 contacts the thermal pipe 2, thereby ensuring that during the welding process, the distance between the welding head and the thermal pipe 2 is always consistent, thereby improving the quality of the welding connection of thermal pipes 2 with different outer diameters and improving the quality of laying thermal pipes 2 with large drop.

[0065] Example 6

[0066] On the basis of Example 1, Figure 8 and Fig. 9 As shown, during the downward movement of the welding gun 11, the fixed block 72 and the slider 73 are in contact with the third guide column 71 respectively, so as to limit the downward movement distance and the swing angle of the welding head, thereby avoiding interference between the welding head and the thermal pipe 2 caused by a stepper motor failure, thereby affecting the efficiency and quality of laying the thermal pipe 2 with a large drop;

[0067] When the angle between the welding gun 11 and the surface of the thermal pipe 2 needs to be changed, the third nut 86 is rotated on the T-shaped rod 84 to move the third nut 86 on the T-shaped rod 84, and the fourth spring 83 provided between the T-shaped rod 84 and the support rod 12 is compressed to generate a rebound force, so as to drive the T-shaped rod 84 to move on the support rod 12, change the distance between the first roller 13 and the third guide column 71, adjust the distance between the welding head and the thermal pipe 2 in the initial state, ensure that the welding head moves down a certain distance, and then rotates to the corresponding angle, so as to meet the welding requirements of thermal pipes 2 of different thicknesses;

[0068] At the same time, by pressing down and rotating the torsion block 76, the torsion block 76 moves from the first vertical slot 77 to the transverse slot 79, and then the applied force is cancelled. The spring force generated by the compression of the fourth spring 83 will drive the torsion block 76 to move from the transverse support to the second vertical slot 78, thereby realizing the rotation of the torsion block 76 on the slider 73. At the same time, since the transverse bar 82 provided on the limit rod 75 contacts the third vertical slot 81 provided on the fourth rotating shaft 80, the limit rod 75 will be driven to rotate on the slider 73, so that the two sides of the limit rod 75 slide out of the limit slot 74, and the restriction on the sliding of the slider 73 in the slide slot 70 is released. Then the slider 73 slides on the swing rod 56. Adjust the range of the swing angle of the welding head to avoid interference between the welding head and the thermal pipe 2 caused by a stepper motor failure, thereby improving the efficiency and quality of laying the thermal pipe 2 with a large drop; after adjusting the position of the slider 73, press and reverse the torsion block 76 again to drive the limit block 22 to rotate in the opposite direction on the slider 73, so that the two sides of the limit rod 75 enter the limit groove 74 again and limit the movement of the slider 73 in the slide groove 70, so as to avoid external force accidentally driving the slider 73 to move, resulting in a change in the rotatable range of the welding head, further preventing the welding head from interfering with the thermal pipe 2, thereby improving the efficiency and quality of laying the thermal pipe 2 with a large drop.
