[0002] Tower solar thermal power generation, as an efficient and environmentally friendly energy conversion technology, has received widespread attention and application in the field of renewable energy in recent years. The main beam assembly is one of the key components of the tower solar thermal power generation system. Its quality and performance directly affect the stability and power generation efficiency of the entire system. Therefore, the welding production line of the main beam assembly plays a vital role in the manufacturing process of tower solar thermal power generation equipment. The welding method of the main beam assembly mostly adopts arc welding or semi-automatic TIG welding. Among them, arc welding has the characteristics of high welding strength, strong adaptability and good flexibility. It is particularly suitable for the welding part of the main beam assembly of tower solar thermal power generation. After welding, the main beam assembly can have a good load-bearing capacity. However, the traditional tower solar thermal power generation main beam assembly welding production line has some shortcomings.

[0003] In the current welding production process of the main beam assembly of tower-type solar thermal power generation, the transportation process of the main beam assembly usually relies on a gantry truck or a crane. When transporting it, the workers in this area must leave and cannot work. This is not only inefficient but also poses a safety hazard. Especially when the main beam assembly is piled up on the auxiliary rack waiting for further processing, it not only takes up a large amount of production space but may also cause harm to the workers due to improper handling.

[0014] The welding method of the main beam assembly welding production line for tower-type solar thermal power generation comprises the following steps:

[0015] S1. First, place the main beam assembly on the top of the support plate, then spot weld the accessories near the side of the support plate. When one of the accessories is welded, the main beam assembly can be rotated to weld the other accessory. After the two accessories are welded to the main beam assembly, the main beam assembly can be moved to the first auxiliary frame using the moving mechanism.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figure 1 - Figure 4 The present invention provides a technical solution: a main beam assembly welding production line for tower-type solar thermal power generation, comprising a ground 1 and a main beam assembly body 3, the upper top of the ground 1 is symmetrically fixedly connected with a welding platform 2, the upper top of the ground 1 is located on the opposite side of the two groups of welding platforms 2 and is provided with a moving mechanism 4, an arc welding robot 5 for arc welding the main beam assembly body 3 is fixedly connected at the center of the upper top of the ground 1, the upper top of the ground 1 is located on both sides of the arc welding robot 5 and is provided with a positioner mechanism 6 for driving the main beam assembly body 3 to rotate, two groups of supporting mechanisms 7 for driving the main beam assembly body 3 to move are symmetrically provided on the upper top of the ground 1, a limiting mechanism 8 for stabilizing the main beam assembly body 3 is provided inside the supporting mechanism 7, a driving mechanism 9 for driving the supporting mechanism 7 and the limiting mechanism 8 to work is provided inside the supporting mechanism 7, and an auxiliary mechanism 10 for regulating the power of the driving mechanism 9 is provided inside the supporting mechanism 7.

[0037] With the above technical solution, the arc welding robot 5 located at the top center of the ground 1 is the core component of the production line. It is responsible for performing high-precision welding work on the main beam assembly body 3, and the arc welding robot 5 adopts arc welding. The metal structure of the arc welding weld is dense and not easily corroded by corrosive media. Therefore, in the harsh environment of tower solar thermal power generation, the arc welding weld can maintain good corrosion resistance. At the same time, the weld surface formed by arc welding is smooth and continuous, and there are fewer internal defects, thereby ensuring good sealing, which is very important for the main beam assembly of tower solar thermal power generation, because the sealing is directly related to the thermal efficiency and safety of the entire system. In the arc welding robot 5 On both sides, a positioner mechanism 6 is specially configured to drive the main beam assembly body 3 to rotate. This mechanism can flexibly adjust the welding angle of the main beam assembly body 3, so that the arc welding robot 5 can complete the welding of various parts without dead angles, greatly improving the welding efficiency and weld quality. The support mechanism 7, their main function is to carry and drive the movement of the main beam assembly body 3 on the production line. The support mechanism 7 is not only equipped with a limiting mechanism 8 to stabilize the main beam assembly body 3, ensuring the stability and safety of the main beam during welding, but also a driving mechanism 9 is provided as the power source of the supporting mechanism 7 and the limiting mechanism 8. The precise control of the driving mechanism 9 makes the entire movement and positioning process smooth and efficient.

[0038] See also Figure 3 - Figure 5 The moving mechanism 4 includes a support frame 41 symmetrically and slidably connected to the top of the ground 1 on one side of the welding platform 2, and a plurality of support plates 44 are symmetrically fixedly connected to the upper top of the support frame 41. The main beam assembly body 3 is placed on the upper top of the support plate 44, and the outer wall of the main beam assembly body 3 is fixedly connected to one side near the support plate 44. The upper top of the ground 1 is located on both sides of the support frame 41 and is slidably connected to a first mobile trolley 45. The upper top of the first mobile trolley 45 is fixedly connected to a hydraulic push rod 46, and the telescopic ends of the two hydraulic push rods 46 are fixedly connected to a limit plate 47. The lower bottom end of the limit plate 47 is evenly arranged with three electric clamping claws 48 for grabbing the main beam assembly body 3.

[0039] Using the above technical solution, the moving mechanism 4 includes a support frame 41 symmetrically slidably connected to the top of the ground 1 and located on one side of the welding platform 2. These support frames 41 not only provide a stable support foundation, but also ensure the stable placement of the main beam assembly body 3 during the movement through several support plates 44 symmetrically fixedly connected to the top of the upper end. The outer wall of the main beam assembly body 3 is fixedly connected with an accessory 31 on one side close to the support plate 44. These accessories are used for connection, fixation or other functional components. The telescopic ends of the two hydraulic push rods 46 are cleverly fixedly connected to the limit plates 47. These limit plates 47 not only play a guiding and positioning role, but also achieve accurate grasping and stable clamping of the main beam assembly body 3 through three electric clamping claws 48 evenly arranged at the lower bottom, ensuring that the main beam assembly body 3 will not be damaged during the grasping process, and can provide sufficient clamping force to prevent shaking or falling off during movement.

[0040] See also Figure 1 - Figure 5 The upper top of the ground 1 is symmetrically fixedly connected with two groups of first auxiliary frames 42 for bearing the main beam assembly body 3. The upper top of the ground 1 is located below the first auxiliary frame 42 and is symmetrically fixedly connected with two groups of second auxiliary frames 43. The upper top of the second auxiliary frame 43 is dampedly connected with the first sleeve frame 431, and the first sleeve frame 431 is slidably connected to the second auxiliary frame 43.

[0041] By adopting the above technical solution, the design of the first auxiliary frame 42 fully considers the weight distribution and transmission requirements of the main beam assembly body 3. Through reasonable layout and solid structure, the load-bearing pressure is effectively dispersed, avoiding structural damage or deformation caused by excessive force on a single point. The second auxiliary frame 43 is not only firmly connected to the ground 1, but also realizes the ability to fine-tune the main beam assembly body 3 in the vertical direction through the first set frame 431 connected by the top damping. This damping connection design not only ensures the stability of the first set frame 431 during movement, but also can provide appropriate buffering and shock absorption effects when necessary, thereby protecting the main beam assembly body 3 from external impact. The first set frame 431 can move smoothly along the guide rail of the second auxiliary frame 43 as needed, thereby adjusting the position of the main beam assembly body 3 on the production line.

The upper top of the fixing plate 63 is fixedly connected to a first electric push rod 64, and the telescopic end of the first electric push rod 64 is fixedly connected to a second set frame 65 that contacts the main beam assembly body 3.

[0043] By adopting the above technical solution, the stability of the entire positioner mechanism 6 is further dispersed through the supporting effect of the tailstock 62, which further disperses the force on the main beam assembly body 3 during the rotation process, ensuring the smoothness and safety of the rotation. The fixed plate 63 not only plays a role of connection and support, but also adds dynamic adjustment capability to the entire positioner mechanism 6 through the first electric push rod 64 fixedly connected to its top end. The telescopic end of the first electric push rod 64 is cleverly fixedly connected to the second frame 65 in contact with the main beam assembly body 3. This design enables the second frame 65 to adjust its height and position as needed, thereby achieving precise clamping and positioning of the main beam assembly body 3.

Then, the arc welding robot 5 can be used to perform arc welding on it to ensure a tight connection between the main beam assembly body 3 and the accessories 31.

[0055] S3. When welding is completed, the first electric push rod 64 and the second sleeve 65 drive the main beam assembly body 3 to move downward and transfer it to the position of the support mechanism 7. The support mechanism 7 will place the two ends of the main beam assembly body 3 on the upper top of the first sleeve 431 respectively, thereby reducing the weight during movement. During the movement of the main beam assembly body 3, the limiting mechanism 8 will always restrain the main beam assembly body 3 to ensure its stability. When it moves to the end of the second auxiliary frame 43, the limiting mechanism 8 no longer restrains it and resets it. Then, under the control of the auxiliary mechanism 10, the power of the driving mechanism 9 is disconnected from the limiting mechanism 8 and connected to the support mechanism 7. At this time, the two third sleeves 74 will flip over, and the main beam assembly body 3 will also realize arc movement, which is convenient for it to slide through the end of the second auxiliary frame 43 for collection.

[0056] For the welding of the main beam assembly body 3: the main beam assembly body 3 is placed on the upper top of the support plate 44. When it needs to be welded, the staff is located above the welding platform 2 and places the accessory 31 against one side of the support plate 44. Then, it is close to the main beam assembly body 3 and pre-welded. When all the accessories 31 are pre-welded, the limit plate 47 and the electric clamping claw 48 are moved down by the extension and contraction of the hydraulic push rod 46, and the main beam assembly body 3 is clamped by the electric clamping claw 48. Then, the telescopic end of the hydraulic push rod 46 rises and is driven by the first moving trolley 45 to move the hydraulic push rod 46. When the first moving trolley 45 drives the hydraulic push rod 46 to move to the position of the first auxiliary frame 42, it can stop and place the main beam assembly body 3 on the upper end of the first auxiliary frame 42. Then, two sets of support mechanisms 7 are used to move to the bottom of the main beam assembly body 3, and the main beam assembly The main beam assembly body 3 is lifted and driven by the supporting mechanism 7 to move to the position of the positioner mechanism 6, and needs to be aligned with the second set frame 65. Then, with the assistance of the staff, the main beam assembly body 3 is clamped inside the positioner main box 61, and its end is abutted by the ejector pin inside the tailstock 62. At the same time, the lower end of the main beam assembly body 3 is lifted by the second set frame 65 and the first electric push rod 64, and now it can be welded by the arc welding robot 5. During the welding process, the positioner main box 61 always drives the main beam assembly body 3 to rotate, thereby achieving close contact between the main beam assembly body 3 and the accessory 31. When welding is completed, the first electric push rod 64 drives the second set frame 65 and the main beam assembly body 3 to move downward. At this time, the supporting mechanism 7 realizes the lifting of the main beam assembly body 3 and drives the main beam assembly body 3 to move above the second auxiliary frame 43.

[0057] As for the lifting work of the support mechanism 7: the telescopic top end of the second electric push rod 72 drives the top plate 73 to rise. At this time, the third sleeve 74 on the top end of the top plate 73 comes into contact with the main beam assembly body 3. Then the second mobile trolley 71 starts to drive the main beam assembly body 3 to slide above the second auxiliary frame 43 until it slides to the end of the second auxiliary frame 43. In order to achieve the rapid release of the main beam assembly body 3, the output end of the drive motor 91 can be used to drive the drive shaft 92 to rotate, and the drive shaft 92 drives the third bevel gear 923 and the second bevel gear 922 to engage and transmit, thereby driving the fixed shaft 781 to rotate. Since the two ends of the fixed shaft 781 are respectively engaged with the first gear 79 The first gear 79 is fixedly connected, so when the two first gears 79 rotate, they will cooperate with the first gear ring 76, and the arc movement of the third frame 74 is realized through the connection between the first gear ring 76 and the third frame 74. At this time, the main beam assembly body 3 inside the third frame 74 is in an inclined state. After applying a thrust to it, it can be easily released, and the main beam assembly body 3 can be rolled through the end of the second auxiliary frame 43, so as to facilitate its collection. In this process, the limiting mechanism 8 will always clamp the main beam assembly body 3, thereby ensuring its stability and avoiding instability caused by the staff or touching other objects during the movement.

[0058] As a supplement to the limiting mechanism 8, the telescopic end of the third electric push rod 101 drives the moving disk 104 to move, and the moving disk 104 is clamped inside the double toothed disk 103. Therefore, the double toothed disk 103 will be engaged with the first toothed disk 102 or the second toothed disk 105 under the drive of the moving disk 104. When engaged with the second toothed disk 105, the output end of the drive motor 91 will drive the support mechanism 7 to work through the drive shaft 92. When engaged with the first toothed disk 102, it will drive the synchronous wheel 93 and the synchronous belt 94 to transmit, thereby causing the auxiliary shaft 95 to rotate, and the fourth bevel gear 97 at the end of the auxiliary shaft 95 will mesh with the two first bevel gears 891 for transmission, thereby driving the two second gears 89 to rotate. Since the fourth bevel gear 97 is located in the middle of the two first bevel gears 891, the two second gears 89 will rotate in different directions. Therefore, after the two second gears 89 are meshed and transmitted with the second gear ring 84, they will push the two fork rods 8 3 and the movable bracket 85 synchronously make an arc movement in the direction of the main beam assembly body 3. Since the movable bracket 85 is rotatably sleeved with the second fixed bracket 86, and the elastic hardness of the damper 88 on the movable bracket 85 is relatively large, it can act as a support when there is no adjustment. At this time, under the connection between the movable bracket 85 and the damper 88 and the support of the damper 88, the arc movement of the limit claw 87 can be achieved and clamped with the main beam assembly body 3. In this way, the connection with the main beam assembly body 3 can be achieved, thereby maintaining stability. When it is necessary to connect the power to the support mechanism 7, the limit claw 87 needs to be reset first so that it is located below the top plate 73, and then the telescopic end of the third electric push rod 101 drives the double toothed disc 103 to separate from the first toothed disc 102 and contact with the second toothed disc 105, so that its second bevel gear 922 can mesh with the third bevel gear 923 and drive the fixed shaft 781 to rotate. At this time, the components of the support mechanism 7 will work again.
