Technical Field
[0001] The utility model relates to the technical field of steel structure welding, in particular to a steel structure welding device for high-rise buildings. Background Technique
[0002] The steel structure is a widely used structure type. The steel structure has high strength, good plasticity and toughness of its materials, can adapt to many building engineering environments with large spans and strong bearing capacities, and is not easily affected by external factors such as weather changes during use, and will not easily deform to affect the building quality, so it can play an important role in building engineering.
[0003] Traditional steel structure connection methods mainly include welding, bolt connection, etc. However, there are some problems with the welding connection method. During the welding process, it is necessary to always keep the distance between the welding torch and the welding point consistent. If the distance between the welding torch and the welding point is too far, it is easy to cause insecure welding, while if the distance is too close, it is easy to cause deformation of the welding point. At the same time, during the welding process of steel structure parts, if the welding surfaces of the two steel structures are not aligned, or the steel structure parts move during the welding process, resulting in welding failure. To solve the above problems, a steel structure welding device for high-rise buildings is provided. Summary of the Utility Model
[0004] In order to overcome the disadvantages mentioned in the above background technique, the utility model provides a steel structure welding device for high-rise buildings.
[0005] The technical solution of the utility model is: a steel structure welding device for high-rise buildings, including a mounting frame, a swing frame and a shaft rod. The swing frame is rotationally connected to the mounting frame through the shaft rod. One side of the mounting frame is provided with a first motor through a mounting seat. The output end of the first motor is fixedly connected to the adjacent shaft rod. The end of the swing frame close to the mounting frame is provided with equally spaced distribution of clamping grooves. The mounting frame is provided with a limiting component for clamping the swing frame. The inner side of the swing frame is fixedly connected with a rotating component for circumferential movement welding. A welding device is installed on the rotating component. The mounting frame is provided with symmetrically distributed annular frames. The annular frames are provided with symmetrically distributed positioning components. The swing frame is fixedly connected with symmetrically distributed hydraulic cylinders. The telescopic end of the hydraulic cylinder is fixedly connected with a clamping plate.
[0006] In one of the embodiments, the damping of the rotation fit between the shaft rod and the mounting frame is less than the gravity of the self-swinging of the swing frame.
[0007] In one of the embodiments, the limiting component includes a sliding frame fixedly connected to the mounting frame. A clamping block matched with the adjacent clamping groove is connected in the sliding frame through a spring. A pull rod penetrating the sliding frame is fixedly connected to the clamping block. A wedge block is fixedly connected to the pull rod.
[0008] In one embodiment, the cross-section of the clamping block is a right-angled triangle, and one side of the right-angled side is close to the swing frame.
[0009] In one embodiment, the rotating assembly includes symmetrically distributed annular plates. The symmetrically distributed annular plates are fixedly connected to the shaft rod. A first external gear ring is rotatably connected between the symmetrically distributed annular plates. On one side of the first external gear ring, a second motor is installed on one of the annular plates. The output end of the second motor is fixedly connected to a transmission gear that meshes with the first external gear ring. An electric push rod is installed inside the first external gear ring, and the welding equipment is installed at the telescopic end of the electric push rod.
[0010] In one embodiment, the positioning assembly includes a second external gear ring rotatably connected to the annular frame. Circumferentially equidistantly rotatably connected to the annular frame are spur gears that mesh with the second external gear ring. On one side of the spur gear, an external gear is connected through a rotating rod. Slidingly connected to the annular frame are equidistantly distributed straight racks. The straight racks mesh with the spur gears. The end of the straight rack is fixedly connected to a fixing block. A cover plate is fixedly connected to the side wall of the annular frame. The lower part of the mounting frame is fixed with a cylinder through a connecting plate. The telescopic end of the cylinder is fixedly connected to a rack frame that meshes with the external gear. A contact rod that cooperates with the wedge block is fixedly connected to the rack frame.
[0011] In one embodiment, the width of the spur gear is greater than the widths of the second external gear ring and the straight rack.
[0012] In one embodiment, the center line of the clamping plate is on the same horizontal plane as the center line of the annular frame.
[0013] The beneficial effects of the present utility model are as follows:
[0014] By the cooperation of the positioning assembly and the two clamping plates approaching each other, the welding surfaces of the two steel structural members can be concentrically arranged, avoiding errors at the welding joint caused by the movement of the steel structural members during the welding process, resulting in the inability to use after welding. The rotating assembly can avoid the problems of insecure welding caused by the welding equipment being too far from the welding joint and easy deformation of the welding joint caused by the welding distance being too close. By the operation of the first motor, the swing frame rotates upward through the shaft rod. While the swing frame swings upward, the welding equipment can synchronously adjust the inclination angle, so as to facilitate the welding work on the inclined surface steel structural members, thereby expanding the welding range of the steel structural members.

Detailed implementation manners
[0023] The embodiments of the present utility model will be described in detail below with reference to the attached drawings.
[0024] A high-rise building steel structure welding device, as Figures 1-7As shown in the figure, it includes a mounting frame 1, a swing frame 2 and a shaft rod 3. Shaft rods 3 are fixedly connected to the front and rear sides of the left end of the swing frame 2. The two shaft rods 3 are respectively rotatably connected to the front and rear ends of the right side of the mounting frame 1. The damping of the rotation fit between the shaft rod 3 and the mounting frame 1 is less than the gravity of the self-swinging of the swing frame 2, avoiding the swing frame 2 quickly swinging downward under its weight and colliding with the ground and being damaged. A first motor 4 is arranged at the rear side of the right side surface of the mounting frame 1 through a mounting seat. The output end of the first motor 4 is fixedly connected to the rear shaft rod 3. Equally spaced card slots 5 are arranged on the outer side surface of the front end of the swing frame 2. A limiting component for positioning the swing frame 2 is arranged on the mounting frame 1. A rotating component for circumferential movement welding is fixedly connected to the inner side of the swing frame 2. A welding device 15 is installed on the rotating component. The mounting frame 1 is provided with symmetrically distributed annular frames 17. Positioning components are arranged on the annular frames 17. Symmetrically distributed hydraulic cylinders 27 are fixedly connected to the swing frame 2. The telescopic end of the hydraulic cylinder 27 is fixedly connected to a clamping plate 28. Driving the clamping plate 28 to move through the hydraulic cylinder 27 can realize the limiting and fixing of the steel structure member. Driving the shaft rod 3 through the first motor 4 to swing the swing frame 2 upward is convenient for welding the steel structure member with an inclined welding surface, but the upward swing angle of the swing frame 2 is less than 90°.
[0025] The limiting component includes a sliding frame 6 fixedly connected to the mounting frame 1. A clamping block 7 that cooperates with the adjacent card slot 5 is connected in the sliding frame 6 through a spring. The cross-section of the clamping block 7 is a right-angled triangle, and one side of the right-angled side is on the right side. A pull rod 8 penetrating the sliding frame 6 is fixedly connected to the bottom of the clamping block 7. A wedge block 9 is fixedly connected to the pull rod 8. Through the cooperation of the clamping block 7 and the card slot 5, the swing frame 2 can be fixed.
[0026] The rotating component includes two annular plates 10 symmetrically distributed left and right. The two annular plates 10 are fixedly connected to the inner sides of the two shaft rods 3. A first external gear ring 11 is rotatably connected between the inner side surfaces of the two annular plates 10. A second motor 12 is installed on the right annular plate 10. The output end of the second motor 12 is fixedly connected to a transmission gear 13 meshing with the first external gear ring 11. An electric push rod 14 is installed on the inner side surface of the first external gear ring 11. The welding device 15 is installed at the telescopic end of the electric push rod 14. The distance between the welding device 15 and the welding position can be controlled through the electric push rod 14, avoiding the problems of insecure welding caused by too far a distance between the welding device and the welding position and easy deformation of the welding position caused by too close a welding distance.
[0027] The positioning component includes a second external gear ring 18 rotatably connected to the annular frame 17. The center line of the clamping plate 28 is on the same horizontal plane as the center line of the annular frame 17. Four spur gears 19 meshing with the second external gear ring 18 are rotatably connected to the annular frame 17 at equal circumferential intervals. An external gear 20 is connected to the spur gear 19 on the front lower side through a rotating rod. Four spur racks 21 are circumferentially and equally spaced and slidably connected to the annular frame 17. The spur racks 21 mesh with the adjacent spur gears 19. The width of the spur gear 19 is greater than the widths of the second external gear ring 18 and the spur rack 21. A fixing block 22 is fixedly connected to the end of the spur rack 21. A cover plate 23 is fixedly connected to the side wall of the annular frame 17. A cylinder 24 is fixed to the lower part of the mounting frame 1 through a connecting plate. A rack frame 25 meshing with the external gear 20 is fixedly connected to the telescopic end of the cylinder 24. A contact rod 26 cooperating with the wedge block 9 is fixedly connected to the rack frame 25. By the operation of the cylinder 24, the rack frame 25 is driven to move to drive the external gear 20 to rotate. The rotation of the external gear 20 causes the spur gear 19 on the front lower side to rotate through the rotating rod on it. The spur gear 19 on the front lower side drives the second external gear ring 18 to rotate. Thus, the remaining spur gears 19 can be rotated to drive the spur racks 21 to move. The movement of the spur racks 21 drives the fixing blocks 22 connected thereto to fix the steel structure parts, avoiding errors at the welding joints caused by the movement of the steel structure parts during the welding process, resulting in the inability to use after welding.
[0028] In use, the operator inserts a steel structure member into the annular frame 17 on the mounting frame 1 from left to right, and moves the steel structure member to the right to a proper position. Then, the cylinder 24 is activated to drive the rack frame 25 to move, transmitting the rotation of the external gear 20. The rotation of the external gear 20 causes the spur gear 19 on the front lower side to rotate through the rotating rod on it. The spur gear 19 on the front lower side drives the second external gear ring 18 to rotate the remaining spur gears 19. Thus, the straight racks 21 on the same annular frame 17 can move synchronously, and the steel structure member is supported and fixed by the fixing block 22 thereon. Subsequently, the operator places another steel structure member between the front and rear clamping plates 28, and activates the front and rear hydraulic cylinders 27 to drive the clamping plates 28 thereon to approach the steel structure member respectively, realizing the fixation of the other steel structure member. At this time, the welding joints of the two steel structure members are close to each other, and the two steel structure members are in a concentric position, facilitating the welding work of the steel structure members. When welding the two steel structure members, the operator activates the electric push rod 14 to move the welding device 15 close to the welding joint (at this time, the distance between the welding device 15 and the welding joint is 1-2 mm), and then closes the electric push rod 14. By means of the electric push rod 14, the problems of insecure welding caused by too large a distance between the welding device 15 and the welding joint and easy deformation of the welding joint caused by too small a welding distance can be avoided. Subsequently, the second motor 12 and the welding device 15 are activated to work. The welding device 15 works to weld the welding joint, and the second motor 12 works to drive the first external gear ring 11 to rotate through the transmission gear 13. The rotation of the first external gear ring 11 drives the electric push rod 14 to move the welding device 15 circumferentially around the welding joint, facilitating the welding work of the steel structure members. After the welding work is completed, the operator turns off the welding device 15 and moves the welding device 15 away from the welding joint by means of the electric push rod 14. Then, the hydraulic cylinder 27 is activated to drive the clamping plate 28 thereon to reset. At the same time, the cylinder 24 works to reset the fixing block 22 to release the fixation of the steel structure member. Then, the operator can take out the welded steel structure member (the steel structure member described above is circular).
[0029] When the welding surface of the steel structure member is an inclined surface, the user repeats the above operations to fix the two steel structure members. During the fixing process of the steel structure members, the inclined surfaces of the two steel structure members both face upward (in the initial state, the swing frame 2 does not swing upward. At this time, the contact rod 26 presses the wedge block 9 so that the clamping block 7 does not cooperate with the card slot 5. After the steel structure member inside the annular frame 17 is fixed, at this time, the contact rod 26 moves away from the wedge block 9, and the clamping block 7 is clamped into the card slot 5 under the action of its spring). Subsequently, the first motor 4 is started to work, and the swing frame 2 rotates upward through the shaft rod 3. During the upward swing of the swing frame 2, the clamping block 7 can be moved out through the card slot 5 on it. When the clamping block 7 coincides with the card slot 5, the clamping block 7 is reset and clamped into the corresponding card slot 5 under the action of its spring. When the distance between the welded joints of the upward-swinging steel structure member and the fixed steel structure member reaches an appropriate position, at this time, the first motor 4 is turned off. While the swing frame 2 swings upward, it can synchronously adjust the inclination angle of the welding device 15. Therefore, it is convenient to carry out the welding work on the steel structure member with an inclined surface. During the above process, the upward swing angle of the swing frame 2 is less than 90°. After the welding work of the steel structure member is completed, the user starts the hydraulic cylinder 27 to drive the clamping plate 28 on it to reset. Subsequently, the welding device 15 is turned off and the welding device 15 is moved away from the welding joint through the electric push rod 14. And the air cylinder 24 works to move the rack frame 25 to reset. During the reset movement of the rack frame 25, the contact rod 26 on it pushes the wedge block 9 to move the pull rod 8 downward. The downward movement of the pull rod 8 drives the clamping block 7 out of the card slot 5 to release the limit on the swing frame 2. The swing frame 2 swings downward under the action of its own weight. Because the damping of the rotation fit between the shaft rod 3 and the mounting frame 1 is less than the gravity of the self-swinging of the swing frame 2, therefore, the downward swing speed of the swing frame 2 can be decelerated, and it is avoided that the swing frame 2 quickly swings downward and resets to collide with the ground and cause damage.
[0030] Through the above steps, the welding surfaces of the two steel structure members can be concentrically arranged, avoiding errors at the welded joints caused by the movement of the steel structure members during the welding process, resulting in the inability to be used after welding, and also avoiding the problems of insufficient welding due to the excessive distance between the welding device 15 and the welded joint and easy deformation of the welded joint due to the too close welding distance.
[0031] The above are only examples of the implementation of the present utility model and are not used to limit the present utility model. All equivalent replacements made within the principle of the present utility model shall be included within the protection scope of the present utility model. The content not elaborated in detail in the present utility model belongs to the well-known prior art of those skilled in the professional field.
