Description

Technical Field

[0001] The invention relates to the technical field of supporting beam welding, and in particular to a green building supporting beam welding device and a welding method thereof. Background Art

[0002] Green building refers to the use of various measures to maximize resource conservation and reduce pollution throughout the life cycle of the building, and to provide residents with healthy, applicable and efficient use space. In order to prevent the deformation or collapse of structures such as floor slabs, walls, beams and columns due to their own weight or external loads during the construction of green buildings, support beams are required to assist in supporting and ensure the stability of the structure. In order to ensure the stability and safety of the support, I-beams are selected as support beams. Due to their unique "I"-shaped cross-sectional design, I-beams have high bending and shear strength and can withstand large loads. When the length of a single support beam is not enough to meet the actual span requirements, two or more beams need to be extended by butt welding the ends to cover the entire area that needs support. In order to accurately locate and fix the position of the I-beam, a rectangular connecting plate is set at the end of the support beam. The use of rectangular connecting plates can make the construction process more standardized and modular, and improve processing efficiency.

[0003] The length of a single support beam is limited. When a support exceeding the length of a single support beam is required, two or more support beams need to be welded so that the length of the support beam meets the usage requirements. A support beam welding device is required when welding the support beams.

[0004] For example, the Chinese invention patent with the authorization announcement number: CN118578028B discloses a butt welding tool for supporting beams used in green building construction and a welding method thereof, which specifically relates to the field of welding tooling. The welding tooling includes a supporting station, a workpiece is placed on the top of the supporting station, and a positioning assembly is arranged on the supporting station. The positioning assembly includes guide wheel 1, guide wheel 2 and guide wheel 3. Guide wheel 1 contacts the side of the workpiece to horizontally position the workpiece, guide wheel 2 contacts the top of the workpiece, guide wheel 3 contacts the bottom of the workpiece, and guide wheel 2 and guide wheel 3 are used to vertically position the workpiece. The present invention sets a supporting mechanism and a movable adjustment component to make the adjustment seat slide in the supporting frame, so that the welding end of the welder and the welding point of the workpiece are in a vertical state. After the welder surrounds the workpiece, the welding end of the welder and the welding point of the workpiece are at the same distance, ensuring uniform distribution of welding energy and consistency of welding quality.

[0005] In the above patent, the two rectangular plates on the support beams to be welded are fixedly connected and then a simple welding operation is performed by surrounding the workpiece with a welder. Since the rectangular plates have a flat structure, the gap at the joint (the position to be welded) of the two rectangular plates is extremely small, and the firmness after welding is not good. In actual application, the support beams play a load-bearing role, and high structural strength requirements are placed on the support beams. If the welding joints of the two support beams are not firm and break, the supported structure will lack auxiliary support and face the risk of collapse. Summary of the invention

[0018] The present invention also provides a welding method of a green building support beam welding device, using the above green building support beam welding device, comprising the following steps:

[0019] S1: The staff first adjusts the spacing between the two limit plates 1 at the top of the movable plate 1 and the movable plate 2 according to the width of the support beam to be welded, and drives the two-way screw rod fixedly connected thereto to rotate by screwing the adjusting handle. At the same time, the kinetic energy is transmitted to the other two-way screw rod through the cooperation of the two transmission gears, so that the two two-way screw rods rotate in opposite directions. Since the threads of the two two-way screw rods are arranged in opposite directions, the two limit plates 1 on each two-way screw rod move to the opposite side. When the two limit plates 1 are adjusted to the appropriate spacing, stop screwing the adjusting handle, and then place the two support beams to be welded on the two limit mechanisms 1 respectively, and the rectangular plates at both ends of each support beam are respectively located on the two sides of the corresponding limit mechanism 1, that is, the movable plate 1 and the movable plate 2 are located between the two rectangular plates. Then, by starting the two limit mechanisms 1, the hydraulic rod 1 in the limit mechanism 1 is extended, pushing the two driving plates to move to the opposite side, and driving the moving plate 2 to move synchronously. The moving plate 2 first moves under the support beam. When the moving plate 2 abuts against the rectangular plate at the end of the support beam, the support beam can be pushed to move, so that the two support beams move to the opposite side. In this process, the rectangular plate at the other end of the support beam abuts against the moving plate 1, and pulls the moving plate 1 to move with the movement of the support beam, which can adapt to support beams of different lengths. The hydraulic rod 1 continues to extend until the rectangular plates on the two support beams to be welded are docked and limited and fixed, so as to achieve limited and fixed left and right directions of the support beams. Subsequently, the limit mechanism 2 is started to limit and fix the vertical direction of the support beam. After the limit and fixation of the support beam to be welded is completed;

[0020] S2: The threaded rod is driven to rotate by the clockwise or counterclockwise rotation of the output end of the servo motor in the moving mechanism, and the moving frame is moved along the axial direction of the threaded rod under the limiting effect of the guide rod on the moving frame, thereby driving the slitting mechanism, the cleaning mechanism and the welding mechanism to move synchronously, and by starting the cutting mechanism, the electric telescopic rod in the cutting mechanism is extended to drive the cutting blade to move to a suitable position, and the cutting motor is started to drive the cutting blade to rotate at high speed, and then the high-speed rotating cutting blade is driven to move by the movement of the moving frame, and the butt joint of the two support beams to be welded (i.e., two butt-jointed rectangular plates) is cut, and a notch is cut at the position to be welded to increase the size of the weld. After one side is cut, the rotating mechanism is started, and the output end of the rotating electric drive rotates to drive the driving gear to rotate, thereby driving the driving gear ring meshing with it to rotate synchronously, and driving the rotating frame to rotate synchronously, until the rotating frame rotates 90°, the rotating motor is turned off, so that the slitting mechanism can perform slitting on the other side of the support beam to be welded (i.e., the other side of the rectangular plate), and so on, the notch can be cut around the butt joint of the two support beams to be welded;

[0021] S3: The operation of the moving mechanism can drive the welding mechanism to move. Before that, the welding mechanism is started first, and the telescopic end of the electric telescopic rod three is extended to drive the welder to move until the welding end of the welder is at a suitable distance from the rectangular plate to be welded on the support beam, and the welder can be used to weld the notches opened on the two butted rectangular plates. When the welding mechanism moves, it drives the connecting rod and the guide column to move synchronously. When the guide column moves in the wavy guide groove, due to the structural characteristics of the wavy guide groove, it can drive the guide column to move back and forth continuously, and then the welding mechanism can be guided back and forth, increasing the welding width and improving the welding quality. After one side of the welding is completed, the rotating frame is driven to rotate 90° through the rotating mechanism, so that the welding mechanism can weld the other side of the support beam to be welded. In this way, the surroundings of the butt joint of the two support beams to be welded can be welded.

[0022] S4: After the rectangular plate is welded once on all sides, the cleaning mechanism is started, and the output end of the cleaning motor rotates to drive the elastic telescopic rod and the straight rod to rotate, thereby driving the knocking ball and the wire brush to make a circular motion, so that the knocking ball indirectly knocks off the slag at the weld position on the rectangular plate, and cooperates with the rotating wire brush to clean the knocked-off welding slag, and through the coordinated use of the moving mechanism, the rotating mechanism and the cleaning mechanism, the welding slag at the welding positions around the rectangular plate can be knocked and cleaned;

[0023] S5: Steps S3 and S4 are repeated cyclically until the notches opened at the joints of the two support beams are welded.

[0024] The present invention has the following beneficial effects:

[0025] 1. The present invention uses a rotating mechanism, a moving mechanism, a cutting mechanism, a rotating frame and other structures in coordination, so as to cut notches around the rectangular plates at the ends of the two supporting beams to be welded after being butted, so as to increase the size of the weld, increase the welding area of ​​the subsequent welding, improve the firmness of the welding of the supporting beam, and reduce the risk of fracture at the welding during subsequent use.

[0026] 2. The present invention can limit and fix the support beam to be welded in multiple directions, such as front, back, up, down, left, and right, by using the limiting mechanism 1 and the limiting mechanism 2 in coordination, thereby improving the stability of the support beam and facilitating improving the welding quality of the support beam.

[0027] 3. The present invention uses two transmission gears in coordination, and can transmit kinetic energy to the other bidirectional screw rod when rotating one of the bidirectional screw rods, thereby synchronously adjusting the distance between the two limit plates 1 at the top of the moving plate 1 and the moving plate 2, which not only ensures the consistency of the distance between the two limit plates 1 at the top of the moving plate 1 and the moving plate 2, improves the limiting effect on the front and rear directions of the support beam, but also simplifies the adjustment steps, eliminates the need for repeated operations, and improves the convenience of equipment use.

[0028] 4. The present invention can knock off and clean the welding slag on the support beam after welding through the setting of the cleaning mechanism. Knocking off the welding slag can avoid the penetration and penetration of the weld, affecting the quality of the welding surface, and ensure that the next layer of welding is unobstructed, so as to facilitate multi-layer welding of the butt joints of the two support beams until the notches at the butt joints of the two support beams are welded solid, thereby greatly improving the welding quality and effect of the support beams.

[0070] The present invention also provides a welding method of a green building support beam welding device, using the above green building support beam welding device, comprising the following steps:

[0071] S1: The staff first adjusts the spacing between the two limit plates 1305 at the top of the movable plate 1301 and the movable plate 2 1302 according to the width of the support beam to be welded, and then rotates the two-way screw rod 1306. At the same time, the kinetic energy is transmitted to the other two-way screw rod 1306 through the cooperation of the two transmission gears 1307, so that the two two-way screw rods 1306 rotate in opposite directions, and because the thread directions of the two two-way screw rods 1306 are set in opposite directions, the two limit plates 1305 on each two-way screw rod 1306 move to the opposite side. When the two limit plates 1305 are adjusted to an appropriate spacing, stop screwing the adjustment handle 17, and then place the two support beams to be welded on the two limit mechanisms 13 respectively, and the rectangular plates at both ends of each support beam are respectively located on the two sides of the corresponding limit mechanism 13, that is, the movable plate 1301 and the movable plate 2 1302 are located on the two rectangular plates Then, by starting the two limiting mechanisms 13, the hydraulic rod 1309 in the limiting mechanism 13 is extended, pushing the two driving plates 1308 to move to the opposite side, and driving the moving plate 1302 to move synchronously. The moving plate 1302 first moves under the support beam. When the moving plate 1302 abuts against the rectangular plate at the end of the support beam, the support beam can be pushed to move, so that the two support beams move to the opposite side. In this process, the rectangular plate at the other end of the support beam abuts against the moving plate 1301, and pulls the moving plate 1301 to move with the movement of the support beam, which can adapt to support beams of different lengths. The hydraulic rod 1309 continues to extend until the rectangular plates on the two support beams to be welded are docked and limited and fixed, so as to achieve limited fixation of the left and right directions of the support beams, and then the limiting mechanism 14 is started to limit and fix the vertical direction of the support beam. After the limit fixation of the support beam to be welded is completed;

[0072] S2: The output end of the servo motor 605 in the moving mechanism 6 rotates clockwise or counterclockwise to drive the threaded rod 602 to rotate, and under the limiting effect of the guide rod 603 on the moving frame 604, the moving frame 604 moves along the axial direction of the threaded rod 602, thereby driving the slitting mechanism 7, the cleaning mechanism 8 and the welding mechanism 9 to move synchronously, and by starting the cutting mechanism, the electric telescopic rod 701 in the cutting mechanism extends to drive the cutting blade to move to a suitable position, and the cutting motor is started to drive the cutting blade to rotate at a high speed, and then the high-speed rotating cutting blade is driven to move by the movement of the moving frame 604, and the two support beams to be welded are welded. The butt joint (i.e., two butted rectangular plates) is subjected to seam cutting, a notch is cut out at the position to be welded, and the size of the weld is increased. After the cutting on one side is completed, the rotating mechanism 10 is started, and the output end of the rotating motor rotates to drive the driving gear 1002 to rotate, thereby driving the driving gear ring 1003 meshing therewith to rotate synchronously, and driving the rotating frame 4 to rotate synchronously, until the rotating frame 4 rotates 90° and the rotating motor 1001 is turned off, so that the seam cutting mechanism 7 can perform seam cutting on the other side of the support beam to be welded (i.e., the other side of the rectangular plate), and so on and so forth, notches can be cut out on all sides of the butt joint of the two support beams to be welded;

[0073] S3: The operation of the moving mechanism 6 can drive the welding mechanism 9 to move. Before that, the welding mechanism 9 is started first, and the telescopic end of the electric telescopic rod 3 901 is extended to drive the welder 902 to move until the welding end of the welder 902 is at a suitable distance from the rectangular plate to be welded on the support beam, and the welder 902 can be used to weld the notches opened on the two butted rectangular plates. When the welding mechanism 9 moves, it drives the connecting rod 1503 and the guide column 1502 to move synchronously. When the guide column 1502 moves in the wavy guide groove 1501, due to the structural characteristics of the wavy guide groove 1501, the guide column 1502 can be driven to move back and forth continuously, so that the welding mechanism 9 can be guided back and forth, increasing the welding width and improving the welding quality. After one side of the welding is completed, the rotating frame 4 is driven to rotate 90° by the rotating mechanism 10, so that the welding mechanism 9 can weld the other side of the support beam to be welded. In this way, the surroundings of the butt joint of the two support beams to be welded can be welded.

[0074] S4: After the rectangular plate is welded once on all sides, the cleaning mechanism 8 is started, and the output end of the cleaning motor 802 rotates to drive the elastic telescopic rod 803 and the straight rod 804 to rotate, thereby driving the knocking ball 805 and the wire brush 806 to make a circular motion, so that the knocking ball 805 indirectly knocks off the slag at the weld position on the rectangular plate, and cooperates with the rotating wire brush 806 to clean the knocked-off welding slag, and through the coordinated use of the moving mechanism 6, the rotating mechanism 10 and the cleaning mechanism 8, the welding slag at the welding positions around the rectangular plate can be knocked and cleaned;

[0075] S5: Steps S3 and S4 are repeated cyclically until the notches opened at the joints of the two support beams are welded.

[0076] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that a plurality of balls 16 distributed in a rectangular array are movably embedded on the top of the movable plate 1 1301 and the movable plate 2 1302 and on the opposite sides of the two limit plates 1 1305, and one end of one of the bidirectional screw rods 1306 is fixedly connected to an adjustment handle 17.

[0077] By setting the ball 16, the friction between the support beam and the limit plate 1305 and the movable plate can be changed from sliding friction to rolling friction, thereby greatly reducing the friction, so that the movable plate can move under the support beam, and reducing the friction when the support beam is placed between the two limit plates 1305, so that the support beam can be placed between the two limit plates 1305. The setting of the adjustment handle 17 makes it convenient for the staff to adjust the spacing of the limit plates 1305 by screwing the bidirectional screw 1306.

[0078] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the limiting mechanism 14 includes an L-shaped bracket 1401 fixedly mounted on the top of the frame 1, a hydraulic rod 1402 is fixedly mounted on the top of the L-shaped bracket 1401, and the telescopic end of the hydraulic rod 1402 is fixedly connected to a limiting plate 1403.

[0079] The extension of the telescopic end of the second hydraulic rod 1402 can drive the second limit plate 1403 to move downward, thereby providing downward pressure on the support beam, thereby limiting and fixing the support beam in the vertical direction.

[0080] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
