Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to a welding device for a solar thermal power generation heliostat column. Background Technology

[0002] Heliostats are the core components of tower-type concentrated solar power (CSP) systems, collecting heat and converting it into electricity through precise reflection of sunlight. The heliostat support column is the core structure supporting the heliostat, and its design and installation precision directly affect the concentrating efficiency and system stability. The heliostat support column is typically fixed to its base by welding.

[0003] Currently, most existing welding equipment aligns and fixes the column and column base to the welding equipment when welding small heliostat columns. Then, the welding gun of the equipment welds the contact point. After completion, it is removed. Then another column and column base are installed and fixed by welding. Because the welded product needs to be removed before the column and column base to be welded can be reinstalled and fixed, the welding efficiency is low and the time is long. Utility Model Content

[0004] The purpose of this invention is to provide a welding device for the pillar of a solar thermal power generation heliostat, so as to solve the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a welding device for a solar thermal power generation heliostat column, comprising:

[0006] The machine base has a rotating disk seat rotatably mounted on its upper side. A support partition is fixed in the middle of the upper side of the rotating disk seat. Top plates are fixed on the top of the front and rear sides of the support partition. A pressing and rotating assembly is mounted on the top plate. Side plates are fixed on the left and right edges of the front and rear sides of the support partition. Limiting clamping assemblies are mounted on the side plates. A controller is mounted on the front side of the machine base.

[0007] Two rotating bases are installed on the front and rear parts of the upper side of the rotating disk base. The two rotating bases are located on the front and rear sides of the supporting partition, respectively. A column base tooling fixture is installed on the rotating base.

[0008] A multi-degree-of-freedom robotic arm is mounted on the rear of the machine base, located behind the rotary table, and equipped with a welding torch.

[0009] Preferably, the extrusion rotation assembly includes a first cylinder, a movable seat, and an extrusion disc. The first cylinder is mounted on the upper side of the top plate, and its output end passes through the top plate and is connected to the movable seat. A rotating column is rotatably mounted on the lower side of the movable seat, and the lower end of the rotating column is connected to the extrusion disc. A servo motor is installed inside the movable seat, and the output end of the servo motor extends out of the movable seat and is connected to a drive gear. A driven gear is fixedly sleeved on the rotating column, and the drive gear and the driven gear are meshed together.

[0010] The first cylinder pushes the moving seat downward, causing the extrusion plate to press against the top of the heliostat column, thus fixing the heliostat column and ensuring close contact between the heliostat column and the column base. The servo motor drives the rotating column to rotate through the transmission between the drive gear and the driven gear. The rotation of the rotating column drives the extrusion plate to rotate, which in turn drives the heliostat column to rotate. When the heliostat column rotates, it can drive the column base to rotate synchronously.

[0011] Preferably, the support partition is provided with vertical slide rails on both the front and rear sides, and the movable seat is fixed with a slide block on the side of the support partition corresponding to the position of the slide rail. The slide block is slidably installed on the slide rail, so that the movable seat moves up and down stably and will not deviate.

[0012] Preferably, the limiting clamping assembly includes two second cylinders mounted on the side plate. The telescopic ends of the two second cylinders penetrate the side plate and are connected to a moving plate. On the side of the moving plate away from the side plate, multiple arc-shaped extrusion parts are installed at equal intervals from top to bottom. The inner walls of the arc-shaped extrusion parts are movably embedded with balls at equal intervals. The second cylinders on the left and right limiting clamping assemblies work synchronously, pushing the corresponding moving plates to move, thereby causing the arc-shaped extrusion parts on the two moving plates to move closer to each other and squeeze and limit the column. The arrangement of the balls reduces the friction between the column and the arc-shaped extrusion parts, facilitating the rotation of the column.

[0013] Preferably, the arc-shaped extrusion members on the left and right limiting clamping assemblies are staggered vertically to facilitate clamping and limiting the column.

[0014] Preferably, the column base fixture and the rotating base are connected by bolts, which is simple and convenient to connect and facilitates the disassembly and replacement of the column base fixture in the future.

[0015] Preferably, a drive motor is installed inside the base. The output end of the drive motor is connected to the lower center of the rotating disk base. The drive motor can drive the rotating disk base to rotate forward and backward, which facilitates the disassembly of another set of welded columns during welding, and also facilitates the installation of a new set of columns and column bases.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. When welding the heliostat column and column base, another set of welded heliostat columns and column bases can be disassembled, and a new set of heliostat columns and column bases to be welded can be installed, which effectively improves work efficiency.

[0018] 2. By installing support partitions, the support partitions can block the debris generated during welding, thus preventing injury to workers who are loading and unloading materials. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figures 1 to 4 The illustrated solar thermal heliostat support welding device includes:

[0028] The machine base 1 has a rotating disk seat 2 rotatably mounted on its upper side. A support partition 3 is fixed in the middle of the upper side of the rotating disk seat 2. Top plates 4 are fixed on the top of the front and rear sides of the support partition 3. A pressing rotating assembly is installed on the top plate 4. Side plates 5 are fixed on the left and right edges of the front and rear sides of the support partition 3. A limit clamping assembly is installed on the side plate 5. A controller is installed on the front side of the machine base 1.

[0029] Two rotating bases 6 are installed on the front and rear sides of the upper side of the rotating disk base 2. The two rotating bases 6 are located on the front and rear sides of the supporting partition 3 respectively. The rotating bases 6 are equipped with column base tooling fixtures 7.

[0030] A multi-degree-of-freedom robotic arm 8 is mounted on the rear of the base 1 and is located behind the rotary table 2. A welding torch 9 is mounted on the multi-degree-of-freedom robotic arm 8.

[0031] The extrusion rotary assembly includes a first cylinder 10, a movable seat 11, and an extrusion disc 12. The first cylinder 10 is installed on the upper side of the top plate 4. The output end of the first cylinder 10 passes through the top plate 4 and is connected to the movable seat 11. A rotating column 13 is rotatably installed on the lower side of the movable seat 11. The lower end of the rotating column 13 is connected to the extrusion disc 12. A servo motor 14 is installed inside the movable seat 11. The output end of the servo motor 14 extends out of the movable seat 11 and is connected to a drive gear 15. A driven gear 16 is fixedly sleeved on the rotating column 13. The drive gear 15 and the driven gear 16 are meshed and connected.

[0032] The first cylinder 10 pushes the moving seat 11 downward, causing the extrusion plate 12 to press the top of the heliostat column, fixing the heliostat column and ensuring close contact between the heliostat column and the column base. The servo motor 14 drives the rotating column 13 to rotate through the transmission between the drive gear 15 and the driven gear 16. The rotation of the rotating column 13 drives the extrusion plate 12 to rotate, which in turn drives the heliostat column to rotate. When the heliostat column rotates, it can drive the column base to rotate synchronously.

[0033] Vertical slide rails are provided on both the front and rear sides of the support partition 3. A slide seat is fixed on the side of the movable seat 11 closest to the support partition 3, corresponding to the position of the slide rail. The slide seat is slidably installed on the slide rail, so that the movable seat 11 moves up and down stably and will not deviate.

[0034] The limiting clamping assembly includes two second cylinders 17, which are mounted on the side plate 5. The telescopic ends of the two second cylinders 17 pass through the side plate 5 and are connected to a moving plate 18. On the side of the moving plate 18 away from the side plate 5, multiple arc-shaped extrusion parts 19 are installed at equal intervals from top to bottom. The inner wall of the arc-shaped extrusion parts 19 is movably inlaid with balls 20 at equal intervals.

[0035] The second cylinders 17 on the left and right limit clamping assemblies work synchronously, pushing the corresponding moving plates 18 to move, so that the arc-shaped extrusion parts 19 on the two moving plates 18 move closer to each other to extrude and limit the column. The setting of the ball bearings 20 reduces the friction between the column and the arc-shaped extrusion parts 19, making it easier for the column to rotate.

[0036] The arc-shaped extrusion parts 19 on the left and right limit clamping components are staggered vertically to facilitate clamping and limiting the column.

[0037] The column base fixture 7 and the rotating base 6 are connected by bolts, which is simple and convenient, and also facilitates the disassembly and replacement of the column base fixture 7 later.

[0038] The base 1 is equipped with a drive motor. The output end of the drive motor is connected to the lower center of the rotating disk base 2. The drive motor can drive the rotating disk base 2 to rotate forward and backward, which makes it convenient to disassemble another set of welded columns during welding, and also facilitates the installation of a new set of columns and column bases.

[0039] In this invention, the column base is installed on the column base fixture 7, and then the heliostat column is placed between the two left and right limiting clamping components, with the heliostat column and the column base abutting and aligned. Then, the second cylinders 17 on the left and right limiting clamping components work synchronously, pushing the corresponding moving plates 18 to move, so that the arc-shaped extrusion parts 19 on the two moving plates 18 move closer to each other to extrude and limit the column. At the same time, the first cylinder 10 on the extrusion rotation component works to push the moving seat 11 down, so that the extrusion plate 12 extrudes the top of the heliostat column, further fixing the heliostat column and making the heliostat column and the column base in close contact. Then, the drive motor in the machine base 1 drives the rotating plate seat 2 to rotate 180 degrees, and the multi-degree-of-freedom robotic arm 8 works with the welding gun 9 to weld it. Next, the servo motor 14 on the extrusion rotating assembly drives the rotating column 13 to rotate through the transmission between the driving gear 15 and the driven gear 16. The rotation of the rotating column 13 drives the extrusion disc 12 to rotate, and the rotation of the extrusion disc 12 drives the heliostat column to rotate. When the heliostat column rotates, it can drive the column base to rotate synchronously, which facilitates welding. During the welding process, a new set of heliostat columns and column bases to be welded can be installed. After the heliostat columns located behind the support partition 3 are welded, the drive motor drives the rotating disc 2 to rotate 180 degrees in the opposite direction, so that the unwelded set can be moved to the back of the support partition 3 for welding. At the same time, the heliostat columns welded in front of the support partition 3 can be removed, and a new set of heliostat columns and column bases to be welded can be installed, which effectively improves work efficiency.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
