[0002] Most of the existing solar thermal power generation devices are tower solar thermal power generation. The widespread use of tower solar thermal power generation can meet the growing demand for electricity. The main beam of the tower solar thermal power generation heliostat bracket is welded by 8 supporting beams, 1 main beam steel pipe, 2 push rod support welded parts, and 1 main beam support welded part. The welding dimensional accuracy of the main beam of the heliostat bracket is high, and practical matching automatic welding equipment is needed to weld the supporting beams to the main beam of the heliostat bracket at equal distances.

[0003] According to the Chinese patent with the announcement number CN111673322A, a multi-station automatic welding method and equipment for the main beam of the heliostat support is disclosed. This invention realizes the multi-station streamlined automatic welding of the main beam of the heliostat support. Under the premise of ensuring the welding quality, it greatly reduces the labor intensity and cost of workers, improves the product welding efficiency, and shortens the production cycle; According to the Chinese patent with the announcement number CN213560865U, a support beam welding positioning device for the main beam of the heliostat support is disclosed. The device can position and clamp the main beam steel pipe and the support beam steel plate to prevent the relative position of the support beam steel plate and the main beam steel pipe from changing during welding; the support beam can be quickly inserted and removed through the spring mechanism, thereby improving the positioning efficiency; while ensuring the dimensional accuracy of the welding, the welding efficiency is improved, and high-quality and efficient welding of the main beam of the tower solar thermal power generation heliostat support is achieved, saving manpower; When the above technical solution is in use, the support beam can be positioned and restricted by the support beam positioning support, so that it can be used for anti-bias welding when welding the main beam and support beam of the heliostat bracket. However, the full welding operation cannot be achieved due to the influence of the support beam positioning support. When the full welding operation is performed subsequently, the support beam positioning support will affect the rapid transfer position of the workpiece, making it difficult to achieve positioning operations for clamping, conveying and slag removal operations of the workpiece during automatic welding.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 10 and Fig.15 The present invention provides a technical solution: a multi-station automatic welding device for the main beam of a heliostat support, comprising a stabilizing seat 1, a spot welding station 2 and a full welding station 6, wherein driving arms 102 are symmetrically arranged at both ends of the stabilizing seat 1, a spot welding station 2 for supporting the main beam is arranged on one side of the stabilizing seat 1, and a plurality of welding robots 3 are arranged on the other side of the stabilizing seat 1, a full welding station 6 is installed on the upper side of the middle part of the stabilizing seat 1, and a plurality of positioning seats 201 for supporting the supporting beam are arranged above the spot welding station 2, and the positioning seats 20 The upper side of the driving arm 102 is a concave structure, which facilitates the main beam to pass through the concave part of the positioning seat 201, and the main beam of the heliostat bracket is transported to the spot welding station 2, and the positioning seat 201 limits the supporting beam sleeved on the outer side of the main beam. A supporting mechanism 4 is provided at one end of the driving arm 102, and the supporting mechanism 4 includes a fan-shaped hanging plate 401 movably connected to the driving arm 102, and one side of the fan-shaped hanging plate 401 is movably connected to an L-shaped seat 402, and a slide rail 405 is fixed parallel to the upper surface of the horizontal side of the L-shaped seat 402; A clamping mechanism 5 is provided on the L-shaped seat 402, and the clamping mechanism 5 includes a support plate 501 slidably docked with the slide rail 405, a sliding sleeve 502 is slidably provided on the outer side of the support plate 501, a vertical cavity is provided on the surface of one side of the support plate 501, and tooth grooves 503 are staggeredly provided on both sides of the inner wall of the vertical cavity, a stopper sleeve 504 is installed on one side of the sliding sleeve 502, a rotating shaft is rotated at the center of the stopper sleeve 504, and a rotating disk 511 is fixed to one end of the rotating shaft extending out of the stopper sleeve 504, a plurality of adjusting grooves 512 with equal angles are provided on the surface of the rotating disk 511, a clamping seat 513 is slidably connected inside the adjusting groove 512, and a clamping rod 514 for tightening the inner wall of the main beam is fixed to one end of the clamping seat 513; A driving motor 101 is installed at the top of both ends of the stabilizing seat 1, the middle of the driving arm 102 is installed with the output end of the driving motor 101, and a counterweight 103 is installed at the end of the driving arm 102 away from the fan-shaped hanging plate 401; a strip slide is opened in the middle of the horizontal side of the L-shaped seat 402, and a screw rod 403 is connected to the strip slide through a bearing, a feed motor 404 is installed on the horizontal side edge of the L-shaped seat 402, and the output end of the feed motor 404 is connected to the screw rod 403, and the bottom of the support plate 501 A threaded sleeve is integrally formed with the screw rod 403. When the welding robot 3 is controlled to automatically spot weld the main beam and the supporting beam, the feed motor 404 on the L-shaped seat 402 is controlled to drive the screw rod 403 to rotate forward, so that the screw rod 403 and the threaded sleeve at the bottom of the support plate 501 are threadedly transmitted, so that the support plate 501 moves forward along the slide rail 405 on the L-shaped seat 402, and the support plate 501 moving forward will drive the plurality of clamping rods 514 at the front of the stop sleeve 504 to be inserted into the end opening of the main beam; The surface of the stopper sleeve 504 close to the sliding sleeve 502 is rotatably connected with a hydraulic cylinder 505, the output end of the hydraulic cylinder 505 is connected with a swing arm 506, the tail of the swing arm 506 is fixed with a sector tooth block 507, the center of the sector tooth block 507 is welded with the rotating shaft; a residual gear a508 is installed at the end of the rotating shaft of the stopper sleeve 504, a transmission gear 509 is meshed below the sector tooth block 507, a residual gear b510 is installed at the coaxial end of the transmission gear 509, and the residual gear a508 and the residual gear b510 are respectively meshed with the clamping teeth on both sides of the tooth groove 503; The adjusting groove 512 is composed of an eccentric groove and a concentric groove, and both the eccentric groove and the concentric groove are arc-shaped structures. The eccentric groove of the adjusting groove 512 and the central axis of the stop sleeve 504 are eccentrically designed, and the concentric groove of the adjusting groove 512 and the central axis of the stop sleeve 504 are coaxially designed. A sliding rod is provided on the inner wall of the stop sleeve 504 near the turntable 511, and the sliding rod is slidably connected to the base 513.

[0021] During specific implementation, the feed motor 404 drives the screw rod 403 to rotate forward, so that the screw rod 403 drives the support plate 501 to move forward along the slide rail 405 on the L-shaped seat 402, so that a plurality of clamping rods 514 are inserted into the end opening of the main beam. At this time, the output end of the hydraulic cylinder 505 is controlled to extend and push the swing arm 506 and the fan-shaped tooth block 507 to rotate forward around the rotating shaft at the center of the stopper sleeve 504, so that the rotating shaft will drive the residual gear a508 at the coaxial end to rotate forward, thereby making the residual gear a508 mesh with the tooth groove 503 on one side of the vertical cavity of the support plate 501, and at the same time the fan-shaped tooth block 507 meshes with the transmission gear 509 The engagement will drive the residual gear b510 to rotate in the opposite direction, so that the residual gear b510 meshes with the tooth groove 503 on the other side of the vertical cavity of the support plate 501. Since the positive rotation tangent direction of the residual gear a508 close to the tooth groove 503 on one side and the reverse rotation tangent direction of the residual gear b510 close to the tooth groove 503 on the other side are both vertically downward, and the bottom of the support plate 501 is supported on the L-shaped seat 402 and cannot move up and down, when the residual gear a508 and the residual gear b510 rotate forward and reverse respectively, the residual gear a508 and the residual gear b510 will move up along the two sets of misaligned tooth grooves 503 to adjust their positions; At the same time, when the hydraulic cylinder 505 drives the rotating shaft to rotate forward, the rotating shaft will drive the rotating disk 511 on the coaxial axis to rotate forward, so that when the rotating disk 511 rotates forward, it will control the clamping rod 514 to get close to the inner wall of the main beam through the adjusting groove 512 on the surface. Specifically, when the rotating disk 511 rotates forward, it will squeeze the clamping seat 513 through the eccentric groove of the adjusting groove 512, so that the clamping seat 513 moves along the sliding rod on the inner wall of the stopper sleeve 504. When the clamping seat 513 moves to the concentric groove of the adjusting groove 512, the clamping seat 513 abuts against the two sides of the inner wall of the concentric groove, which will make the inner wall of the concentric groove limit the position of the clamping seat 513, ensuring that the clamping rod 514 at one end of the clamping seat 513 abuts against the inner wall surface of the main beam. When the hydraulic cylinder 505 pushes the rotating shaft in the center of the stopper sleeve 504 to rotate forward, the residual gear a508 and the residual gear b510 will be lifted along the support plate 501, and then the clamping rods 514 distributed at equal angles on one side of the turntable 511 will move up from the center position of the main beam opening. At the same time, the clamping rods 514 distributed at equal angles will be squeezed and move away from each other when moving up as a whole, thereby ensuring that the clamping mechanism 5 can complete the positioning and lifting of the cylindrical main beam on the supporting mechanism 4 by first moving up and then tightening, so as to facilitate the main beam that has completed the spot welding process to drive the supporting beam to detach from the positioning seat 201; When the driving motor 101 drives the driving arm 102 to flip, the fan-shaped hanging plate 401 will move from the spot welding station 2 to the full welding station 6. Since the support beam is originally inserted into the upper side of the positioning seat 201, the workpiece is moved upward by driving the clamping mechanism 5 when clamping, which can drive the support beam to separate from the positioning seat 201, so that the heliostat support workpiece can be quickly released from the positioning restriction during assembly and spot welding operations due to the positioning and anti-biasing restrictions. Since the clamping mechanism 5 is located on the horizontal side of the L-shaped seat 402, and the workpiece is positioned and clamped by two sets of clamping mechanisms 5 to move the position, when the fan-shaped hanging plate 401 changes its position, the L-shaped seat 402 will always be vertically downward to ensure the stability of the movement. Qualitatively, when the flipped driving arm 102 drives the workpiece to be placed on the driving roller 8 at the top of the full welding station 6 through the fan-shaped hanging plate 401 at one end, the counterweight block 103 at the other end of the driving arm 102 will flip accordingly, which can reduce the resistance of the driving motor 101 when rotating; when the main beam of the heliostat bracket is overlapped on the driving roller 8, the support beam that has been spot-welded on the outside of the main beam will slide and insert along one side of the semicircular middle plate 702 and the side plate 703, and the middle plate 702 and the side plate 703 can be used to prevent the two sides of the support beam from deflection. When the driving roller 8 rotates, it can drive the main beam to rotate in a circle, so that the welding robot 3 can perform 360° welding on the butt gap between the main beam and the support beam.

[0022] See also Figure 1 , Figure 2 , Figure 11-Figure 14 , a plurality of anti-deviation scraping assemblies 7 and driving rollers 8 are arranged on the upper surface of the full welding station 6, the anti-deviation scraping assemblies 7 include a pad 701 installed on the upper side of the full welding station 6, an intermediate plate 702 and two parallel side plates 703 are welded above the pad 701, the intermediate plate 702 and the side plates 703 are both semicircular structures, so the support beam will not be affected by the interference of the intermediate plate 702 and the side plates 703 during rotation, the surfaces of the intermediate plate 702 and the side plates 703 are provided with slide grooves 708, a triggering member 704 is arranged between the two side plates 703, and the surfaces of the intermediate plate 702 and the side plates 703 are movably connected with a rapping arm 706 for removing welding slag; An extrusion rod 7041 penetrating the slide groove 708 is fixed on both sides of the trigger member 704, an inner cavity is opened below the middle plate 702, and a cross arm sliding with the inner cavity is provided in the middle of the trigger member 704, and a reset spring 705 is connected between the lower wall of the inner cavity and the lower wall of the cross arm, a scraping tooth 707 is integrally formed at the upper end of the vibrating arm 706, and a strip extrusion groove slidably docked with the extrusion rod 7041 is opened on the lower end surface of the vibrating arm 706.

[0023] In specific implementation, when the main beam and the supporting beam are fully welded, the scraper 707 is driven to fit the welding part through the vibration arm 706 between the middle plate 702 and the side plate 703, so that the scraper 707 can scrape off the welding slag produced by the welding, and when the supporting beam rotates and squeezes the top wall of the trigger member 704 between the middle plate 702 and the side plate 703, the trigger member 704 can squeeze the reset spring 705 when it moves downward, so that the trigger member 704 moves downward along the slide groove 708 through the squeezing rod 7041, so that the squeezing rod 7041 will squeeze the vibration The strip extrusion groove at the lower end of the beating arm 706 allows the beating arm 706 to rotate downward and away from the main beam. When the rotating support beam is disengaged from the extrusion of the trigger member 704, the reset spring 705 pushes the trigger member 704 upward, so that the extrusion rod 7041 on the trigger member 704 pulls the beating arm 706 upward to rotate and reset, thereby facilitating the beating arm 706 to drive the scraper teeth 707 at the upper end to rotate and hit the outer wall of the main beam, and then intermittently knock on the welding parts, ensuring that the workpiece of the heliostat bracket can quickly remove the welding slag generated by the full welding operation.

[0024] See also Figure 4-Figure 6 An arc-shaped rack 406 is fixed to the lower edge of the vertical side of the L-shaped seat 402. The arc-shaped rack 406 and the rotation center of the fan-shaped suspension plate 401 are distributed in concentric circles. A steering motor 407 is embedded and installed on the surface of the fan-shaped suspension plate 401. The output end of the steering motor 407 is provided with a steering gear 408 meshing with the arc-shaped rack 406.

[0025] In a specific implementation, the steering motor 407 is started to drive the steering gear 408 at the output end to rotate forward or reverse, so that the steering gear 408 can drive the arc-shaped rack 406 to deflect forward or reverse, so that the arc-shaped rack 406 can drive the L-shaped seat 402 to deflect at an angle. When the L-shaped seat 402 is at a deflection angle, it can drive the clamping mechanism 5 to change its position, so that the two groups of clamping mechanisms 5 can pull the cylindrical workpiece of the heliostat bracket to change its position, and the workpiece can be sent to the full welding station 6 for automatic welding to achieve an adjustable docking effect. In addition, the steering motor 407 drives the L-shaped seat 402 and the clamping mechanism 5 to change their positions, so that the cylindrical workpiece of the heliostat bracket can be quickly driven to swing as a whole, so that impurities on the workpiece can be quickly removed.

The two ends of the V-shaped roller are installed on the spot welding station 2 and the punching station 9 through a bearing seat, and a synchronous wheel is also installed on the V-shaped roller.

[0027] In the specific implementation, the support beam is positioned and inserted on the positioning seat 201 of the spot welding station 2, so that the center of the middle part of the support beam coincides with the inner concave center axis of the upper side of the positioning seat 201, and a drilling device is installed on the punching station 9 for drilling holes on the surface of the main beam. Then, the main beam of the heliostat bracket is linearly transported to the conveying assembly of the spot welding station 2 by the conveying assembly on the punching station 9, and one end of the main beam is limited and blocked by a limit baffle. Then, the main beam and the support beam are pre-spot welded by the multi-station welding robot 3. After the main beam and the support beam are spot welded, the support mechanism 4 at both ends of the stabilizing seat 1 is used to drive the clamping mechanism 5 to be inserted into the two ends of the main beam, and the drive motor 10 is controlled. 1 drives the supporting mechanism 4 to adjust the position so that the workpiece that has been spot welded is sent to the full welding station 6. Then, the hydraulic cylinder 505 is contracted to reverse the rotating shaft, thereby driving the turntable 511 to reverse and drive a plurality of clamping rods 514 to approach each other and break away from the contact with the inner wall of the main beam opening. At the same time, the residual gear a508 and the residual gear b510 can move down along the tooth groove 503 on the inner wall of the support plate 501 to ensure that the stopper sleeve 504 and the sliding sleeve 502 move down along the support plate 501 to adjust the position, and start the feed motor 404 to drive the screw rod 403 to reverse, so that the screw rod 403 drives the support plate 501 to drive the clamping mechanism 5 to move in the opposite direction along the slide rail 405 and away from the end of the main beam. After the welding robot 3 completes the full welding of the main beam and the supporting beam of the workpiece, the walking track 11 on the steel frame 10 is used to drive the lifting arm 12 to move horizontally in a straight line, and the lifting arm 12 drives two sets of mechanical clamps 13 to move down to clamp the fully welded workpiece. Finally, the lifting arm 12 drives the two sets of mechanical clamps 13 to move up, and the workpiece is driven to be transported to the next workstation for operation under the horizontal movement of the walking track 11. This is the existing technology and will not be elaborated here.
