Description

Technical Field

[0001] The present invention relates to the technical field of steel structure welding, and specifically relates to a welding auxiliary positioning device for building steel structure construction. Background Art

[0002] A steel structure is an engineering structure composed of steel materials such as steel plates, round steel, steel pipes, steel cables, and various profiled steels through processing, connection, and installation. It is an indispensable structural form in modern construction projects and is also one of the main building structural types.

[0003] Specifically, a steel structure is mainly composed of components such as steel beams, steel columns, and steel trusses made of profiled steels and steel plates. Welds, bolts, or rivets are usually used to connect between the components or parts. Due to its characteristics such as light self-weight, simple construction, high tensile strength, good overall rigidity, and strong deformation ability, this structure is widely used in many fields such as large factories, stadiums, super high-rise buildings, bridges, main power plant buildings of thermal power plants, boiler steel frames, transmission and transformation iron towers, radio and television communication towers, offshore oil platforms, nuclear power plants, wind power generation, and water conservancy construction.

[0004] A steel truss is a type of steel structure and is widely used in the fields of roof structures, crane girders, bridges, and hydraulic gates of industrial and civil buildings. Commonly, steel trusses are used as the main load-bearing components. For example, in mast towers, television towers, and transmission line towers, space steel trusses composed of three-sided, four-sided, or multi-sided planar trusses are commonly used.

[0005] However, due to the various angular arrangements of the connecting components between the upper chord and the lower chord of the steel truss during the welding process, it is difficult to accurately position the angles of the connecting components in the prior art, or the positioning takes a long time, resulting in low welding efficiency. Therefore, a welding auxiliary positioning device is needed to quickly and accurately position the connecting components. Summary of the Invention

Specific embodiments

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] In addition, an element in the present invention is referred to as being "fixed to" or "disposed on" another element, which can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0052] Please refer to Figures 1 to 14, in the embodiment of the present invention, a welding auxiliary positioning device for building steel structures is used to assist in welding a plurality of connecting rods 3 between two adjacent chord frames 2. There are three chord frames 2, which are distributed in an equilateral triangle. The ends of the three chord frames 2 are fixed by a tripod 1. The plane formed between two adjacent chord frames 2 is a welding working surface. This welding auxiliary positioning device for building steel structures is used to alternately position a plurality of connecting rods 3 in a positive and negative manner along the length direction of the welding working surface in sequence; the welding auxiliary positioning device for building steel structures includes a frame body 4 and universal wheels 5 fixedly arranged at the bottom of the frame body 4. A first support 6 and a second support 7 are respectively fixedly arranged on the frame body 4. A pin shaft 8 is rotatably arranged on the first support 6, and a receiving frame 9 is rotatably arranged on the pin shaft 8;

[0053] A limiting component is arranged between the first support 6 and the receiving frame 9, and the limiting component causes the receiving frame 9 to be in a balanced position;

[0054] A blanking component for storing a plurality of connecting rods 3 is arranged on the frame body 4, and the plurality of connecting rods 3 will fall into the receiving frame 9 in sequence under the action of the blanking component;

[0055] An elastic clamping component is arranged on the receiving frame 9. The elastic clamping component is connected to the pin shaft 8 through a synchronous structure. When the elastic clamping component operates, it can clamp and fix the connecting rod 3 falling into the receiving frame 9, and the pin shaft 8 will also rotate accordingly;

[0056] A yawing component cooperating with the receiving frame 9 is arranged on the second support 7. The yawing component is connected to the pin shaft 8 through a transmission structure. When the pin shaft 8 rotates, the transmission structure will drive the yawing component to act. The yawing component will cooperate with the receiving frame 9 to cause the receiving frame 9 and the connecting rod 3 clamped therein to deflect;

[0057] An elastic locking component is arranged on the second support 7. The elastic locking component is connected to the yawing component and cooperates with the chord frame 2. When the yawing component acts, the elastic locking component will abut against the chord frame 2, so that a locking state is formed between the frame body 4 and the chord frame 2.

[0058] In this solution, through the arranged blanking component, multiple connecting rods 3 fall into the receiving rack 9 in sequence. The receiving rack 9 will maintain a balanced state under the action of the limiting component. When the elastic clamping component acts, it can not only clamp and fix the connecting rods 3 falling into the receiving rack 9, but also the pin shaft 8 will rotate following through the synchronization structure. During this process, the yaw component will act following the pin shaft 8 through the transmission structure. When the yaw component runs to the critical value, it will instantaneously deflect rapidly and cooperate with the receiving rack 9, thereby driving the receiving rack 9 and the connecting rods 3 to deflect, so that the connecting rods 3 are accurately and rapidly adapted to the two chord racks 2, facilitating the improvement of the welding efficiency. At the same time, during the operation of the yaw component, the elastic locking component will abut against the chord rack 2, so that a locking state is formed between the frame body 4 and the chord rack 2, avoiding displacement during the welding process and improving the welding stability.

[0059] In this application, through the mutual cooperation among the receiving rack 9, the pin shaft 8, the blanking component, the limiting component, the elastic clamping component, the synchronization structure, the yaw component, the transmission structure and the elastic locking component, it can not only drive the receiving rack 9 and the connecting rods 3 clamped inside the receiving rack 9 to deflect, so as to be accurately and rapidly adapted to the two chord racks 2, improving the welding efficiency, but also can avoid displacement during the welding process and improve the welding stability.

[0060] Please refer to Figure 3 , the blanking component includes a feed hopper 10 fixedly arranged on the frame body 4 and a baffle 11 horizontally slidably arranged on the feed hopper 10. The cross-section of the feed hopper 10 is funnel-shaped, and the bottom width of the feed hopper 10 is the same as the diameter of the connecting rod 3. The baffle 11 is located at the bottom of the feed hopper 10;

[0061] An electric push rod 12 is fixedly arranged on the frame body 4, and the output end of the electric push rod 12 is fixedly connected to one end of the baffle 11.

[0062] In this embodiment, since multiple connecting rods 3 are stored in the feed hopper 10, and the cross-section of the feed hopper 10 is funnel-shaped and the bottom width of the feed hopper 10 is the same as the diameter of the connecting rod 3, under the action of gravity, multiple connecting rods 3 will all have a tendency to be discharged from the feed hopper 10;

[0063] Also, because a baffle 11 is horizontally slidably arranged on the feed hopper 10, the baffle 11 is located at the bottom of the feed hopper 10, and an electric push rod 12 is fixedly arranged on the frame body 4, and the output end of the electric push rod 12 is fixedly connected to one end of the baffle 11. Therefore, by driving the baffle 11 to slide horizontally through the electric push rod 12, multiple connecting rods 3 in the feed hopper 10 can be discharged one by one.

[0064] Please refer to Figure 7, the limiting component includes a centering rod 13 fixedly arranged on the first bracket 6 and a semi-circular groove 14 formed on the side wall of the material receiving frame 9, and the center of the semi-circular groove 14 is on the same straight line as the axis of the pin shaft 8;

[0065] A centering block 15 is slidably arranged inside the semi-circular groove 14. The centering block 15 is fixedly connected to the centering rod 13. Two first springs 16 are fixedly arranged on both sides of the centering block 15 inside the semi-circular groove 14. Under the action of the first springs 16, the centering block 15 is always located in the middle of the semi-circular groove 14.

[0066] In this embodiment, since the centering block 15 is slidably arranged inside the semi-circular groove 14 and two first springs 16 are fixedly arranged on both sides of the centering block 15 inside the semi-circular groove 14, the centering block 15 is always located in the middle of the semi-circular groove 14 without external force;

[0067] Also, because the center of the semi-circular groove 14 is on the same straight line as the axis of the pin shaft 8, and the centering block 15 is connected to the first bracket 6 through the centering rod 13, therefore, the material receiving frame 9 will always remain stationary with respect to the first bracket 6 without external force.

[0068] Please refer to Figure 10 , the elastic clamping component includes a U-shaped frame 17 fixedly arranged on the material receiving frame 9 and a lead screw 18 rotatably arranged on the U-shaped frame 17. A moving rod 19 is slidably arranged on the material receiving frame 9;

[0069] The moving rod 19 is in threaded cooperation with the lead screw 18, and a knob 20 is fixedly arranged at the other end of the lead screw 18;

[0070] One end of the moving rod 19 is fixedly provided with a moving plate 21. The moving plate 21 is located inside the material receiving frame 9. An arc-shaped clamping plate 23 is arranged inside the material receiving frame 9. The arc-shaped clamping plate 23 is slidably matched with the moving plate 21 through a connecting column 22;

[0071] A second spring 24 is sleeved outside the connecting column 22, and both ends of the second spring 24 are abutted against the moving plate 21 and the arc-shaped clamping plate 23 respectively.

[0072] In this embodiment, after the connecting rod 3 falls into the material receiving frame 9, when the moving plate 21 drives the arc-shaped clamping plate 23 to move closer to the connecting rod 3 through the connecting column 22 and the second spring 24, the arc-shaped clamping plate 23 will cooperate with the material receiving frame 9 to clamp and fix the connecting rod 3. Among them, due to the existence of the second spring 24, the fixing of the connecting rod 3 will be elastic clamping;

[0073] Moreover, since the moving rod 19 is slidably arranged on the material receiving frame 9, and the moving rod 19 is in threaded cooperation with the lead screw 18, and the moving plate 21 is fixedly connected to the moving rod 19, therefore, when the lead screw 18 is rotated by the knob 20, the moving rod 19 will drive the moving plate 21 to approach the connecting rod 3.

[0074] Please refer to Figure 7 、 Figure 10 , the synchronization structure includes a first driving wheel 25 fixedly arranged on the lead screw 18 and a second driving wheel 26 fixedly arranged on the pin shaft 8, and the first driving wheel 25 and the second driving wheel 26 are connected by a belt 27.

[0075] In this embodiment, since the first driving wheel 25 fixed on the lead screw 18 and the second driving wheel 26 fixed on the pin shaft 8 are connected by a belt 27, during the rotation of the lead screw 18, the pin shaft 8 will follow the rotation.

[0076] Please refer to Figure 8 、 Figure 14 , the yaw assembly includes a sleeve 28 and a slide rod 29 slidably engaged with the sleeve 28. A rotating shaft 30 is rotatably arranged on the second bracket 7, and a yaw rod 31 is fixedly arranged on the rotating shaft 30;

[0077] One end of the sleeve 28 is rotatably connected to the second bracket 7, and one end of the slide rod 29 is rotatably connected to one end of the yaw rod 31;

[0078] A third spring 32 is arranged inside the sleeve 28, and both ends of the third spring 32 are abutted against the other end of the slide rod 29 and the inner side wall of the other end of the sleeve 28 respectively;

[0079] A mating rod 33 is fixedly arranged on the material receiving frame 9. During the rotation of the yaw rod 31, the yaw rod 31 will cooperate with the mating rod 33 and drive the material receiving frame 9 to yaw. A limiting rod 34 corresponding to the yaw rod 31 is fixedly arranged on the second bracket 7.

[0080] In this embodiment, since the sleeve 28 and the sliding rod 29 are in sliding fit, one end of the sleeve 28 is rotatably connected to the second bracket 7, a rotating shaft 30 is rotatably arranged on the second bracket 7, a swing rod 31 is fixedly arranged on the rotating shaft 30, one end of the sliding rod 29 is rotatably connected to one end of the swing rod 31, and both ends of the third spring 32 are respectively abutted against the other end of the sliding rod 29 and the inner side wall of the other end of the sleeve 28. Therefore, when the rotating shaft 30 rotates, the swing rod 31 will follow the rotation. During this process, the sleeve 28 and the sliding rod 29 will be in sliding fit and further compress the third spring 32. When the swing rod 31, the sleeve 28 and the sliding rod 29 rotate to be in the same straight line and then deflect a little more, the third spring 32 will instantly release the elastic force and drive the swing rod 31 to rotate quickly;

[0081] Also, since a matching rod 33 is fixedly arranged on the material receiving frame 9 and the matching rod 33 corresponds to the swing rod 31, during the rotation of the swing rod 31, the swing rod 31 will cooperate with the matching rod 33 and drive the material receiving frame 9 to swing, so that the connecting rod 3 clamped in the material receiving frame 9 swings. Among them, the arranged limiting rod 34 is used to position the swing rod 31 to prevent the swing rod 31 from rotating excessively.

[0082] Please refer to Figure 7 、 Figure 8 、 Figure 11 As shown in, the transmission structure includes a connecting plate 35 and a rotating rod 36 rotatably arranged on the connecting plate 35. Both ends of the connecting plate 35 are respectively rotatably connected to the pin shaft 8 and the rotating shaft 30;

[0083] One end of each of the two ends of the rotating rod 36 is fixedly provided with a first bevel gear 37 and a second bevel gear 38 respectively. A third bevel gear 39 meshing with the first bevel gear 37 is fixedly arranged on the pin shaft 8, and a fourth bevel gear 40 meshing with the second bevel gear 38 is fixedly arranged on the rotating shaft 30.

[0084] In this embodiment, since the first bevel gear 37 and the third bevel gear 39 are meshed with each other, and the second bevel gear 38 and the fourth bevel gear 40 are meshed with each other, when the pin shaft 8 rotates, the rotating rod 36 will drive the rotating shaft 30 to rotate.

[0085] Please refer to Figure 4 、 Figure 11 As shown in, the elastic locking assembly includes a socket 41 and a sliding column 42 slidably matched with the socket 41. The socket 41 is slidably arranged on the second bracket 7 through an L-shaped plate 43, and one end of the sliding column 42 is fixedly provided with an arc-shaped pressing plate 44 cooperating with the chord frame 2;

[0086] Inside the socket 41, a fourth spring 45 is provided, and both ends of the fourth spring 45 are respectively abutted against the other end of the sliding column 42 and the inner side wall of the socket 41 away from one end of the sliding column 42;

[0087] One end of the rotating shaft 30 is fixedly provided with a disc 46, one end of the socket 41 close to the disc 46 is fixedly provided with a roller 47, and the roller 47 is in fit with the disc 46. A beveled block 48 matched with the roller 47 is fixedly provided on one side of the disc 46 close to the socket 41.

[0088] In this embodiment, since the arc-shaped pressing plate 44 is fixedly provided on the sliding column 42 and the arc-shaped pressing plate 44 is in fit with the chord frame 2, when the sliding column 42 drives the arc-shaped pressing plate 44 to move towards the chord frame 2 and abut against it, by using the frictional force between the arc-shaped pressing plate 44 and the chord frame 2, the universal wheel 5 cannot move, that is, the whole device always remains stationary during the welding process;

[0089] Also, because the socket 41 and the sliding column 42 are in sliding fit, and the socket 41 is slidably arranged on the L-shaped plate 43, when the socket 41 drives the sliding column 42 to move towards the chord frame 2, it is okay; since a fourth spring 45 is provided inside the socket 41, and both ends of the fourth spring 45 are respectively abutted against the other end of the sliding column 42 and the inner side wall of the socket 41 away from one end of the sliding column 42, under the action of the fourth spring 45, the arc-shaped pressing plate 44 and the chord frame 2 are elastically pressed;

[0090] Since a roller 47 is fixedly provided at one end of the socket 41, and the roller 47 is in fit with the disc 46, and a beveled block 48 matched with the roller 47 is fixedly provided on one side of the disc 46, therefore, when the rotating shaft 30 rotates, the disc 46 will drive the beveled block 48 to cooperate with the roller 47, so that the socket 41 slides on the L-shaped plate 43 towards the chord frame 2.
