It is an indispensable structural form in modern construction projects and one of the main types of building structures.

[0003] Specifically, steel structures are mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and the components or parts are usually connected by welds, bolts or rivets. This structure is widely used in many fields such as large factories, venues, super high-rise buildings, bridges, thermal power plant buildings, boiler steel frames, power transmission and transformation towers, radio and television communication towers, offshore oil platforms, nuclear power plants, wind power generation, and water conservancy construction due to its light weight, simple construction, high tensile strength, good overall rigidity, and strong deformation capacity.

[0004] Steel truss is a kind of steel structure. It is widely used in industrial and civil building roof structures, crane beams, bridges and hydraulic gates. Steel trusses are often used as the main load-bearing components, such as mast towers, TV towers and transmission line towers. Spatial steel trusses composed of three-sided, four-sided or multi-sided plane trusses are often used.

[0005] However, since the connecting components between the upper chord and the lower chord of the steel truss are arranged at various angles during the welding process, it is difficult to accurately position the angle of the connecting components in the prior art, or the positioning takes a long time, and the welding efficiency is low.

When the elastic clamping assembly is in operation, the connecting rod 3 falling into the receiving rack 9 can be clamped and fixed, and the pin shaft 8 will also rotate accordingly; The second bracket 7 is provided with a deflection assembly that cooperates with the material receiving frame 9. The deflection assembly is connected to the pin shaft 8 through a transmission structure. When the pin shaft 8 rotates, the transmission structure will drive the deflection assembly to move, and the deflection assembly will cooperate with the material receiving frame 9 to cause the material receiving frame 9 and the connecting rod 3 clamped therein to deflect; The second bracket 7 is provided with an elastic locking assembly, which is connected to the deflection assembly and cooperates with the string frame 2. When the deflection assembly is in motion, the elastic locking assembly will abut against the string frame 2, so that the frame body 4 and the string frame 2 are in a locked state.

[0037] In the present scheme, a plurality of connecting rods 3 are sequentially dropped into the material receiving rack 9 by means of a feeding assembly, and the material receiving rack 9 will maintain a balanced state under the action of the limit assembly. When the elastic clamping assembly is actuated, it will not only clamp and fix the connecting rod 3 dropped into the material receiving rack 9, but also the pin shaft 8 will rotate along with it through the synchronous structure. During this process, the deflection assembly will follow the pin shaft 8 to move through the transmission structure. When the deflection assembly reaches a critical value, it will instantly deflect rapidly and cooperate with the material receiving rack 9, thereby driving the material receiving rack 9 and the connecting rod 3 to deflect, so that the connecting rod 3 and the two string frames 2 are accurately and quickly adapted to each other, so as to improve the welding efficiency. At the same time, during the operation of the deflection assembly, the elastic locking assembly will abut against the string frame 2, so that the frame body 4 and the string frame 2 are in a locked state, thereby avoiding displacement during welding and improving the stability of welding.

[0038] In the present application, through the mutual cooperation between the material receiving frame 9, the pin shaft 8, the material discharge assembly, the limit assembly, the elastic clamping assembly, the synchronization structure, the deflection assembly, the transmission structure and the elastic locking assembly, it can not only drive the material receiving frame 9 and the connecting rod 3 clamped inside the material receiving frame 9 to deflect, so as to accurately and quickly adapt to the two string frames 2, thereby improving the welding efficiency, but also can avoid displacement during the welding process, thereby improving the stability of welding.

[0039] See also Figure 3 The material unloading assembly includes a material box 10 fixedly arranged on the frame 4 and a baffle 11 horizontally slidably arranged on the material box 10. The cross section of the material box 10 is funnel-shaped, and the bottom width of the material box 10 is the same as the diameter of the connecting rod 3. The baffle 11 is located at the bottom of the material box 10; An electric push rod 12 is fixedly disposed on the frame 4 , and an output end of the electric push rod 12 is fixedly connected to one end of the baffle 11 .

[0040] In this embodiment, since the plurality of connecting rods 3 are stored in the material box 10, and the cross section of the material box 10 is funnel-shaped, the bottom width of the material box 10 is the same as the diameter of the connecting rod 3, under the action of gravity, the plurality of connecting rods 3 will tend to be discharged from the material box 10; Because a baffle 11 is horizontally slidably provided on the material box 10, the baffle 11 is located at the bottom of the material box 10, and an electric push rod 12 is fixedly provided on the frame 4, and the output end of the electric push rod 12 is fixedly connected to one end of the baffle 11, therefore, the baffle 11 is driven by the electric push rod 12 to slide horizontally, so that multiple connecting rods 3 in the material box 10 can be released one by one.

[0041] See also Figure 7 The limiting assembly includes a center rod 13 fixedly arranged on the first bracket 6 and a semicircular groove 14 provided on the side wall of the receiving frame 9, and the center of the semicircular groove 14 is in the same straight line as the axis of the pin shaft 8; A centering block 15 is slidably arranged inside the semicircular groove 14, and the centering block 15 is fixedly connected to the centering rod 13. Two No. 1 springs 16 are fixedly arranged in the semicircular groove 14 and on both sides of the centering block 15. Under the action of the No. 1 springs 16, the centering block 15 is always located in the middle of the semicircular groove 14.

[0042] In this embodiment, since a centering block 15 is slidably disposed inside the semicircular groove 14, and two No. 1 springs 16 are fixedly disposed inside the semicircular groove 14 and on both sides of the centering block 15, the centering block 15 is always located in the middle of the semicircular groove 14 when no external force is applied; Because the center of the semicircular groove 14 is in the same straight line as the axis of the pin shaft 8, and the centering block 15 and the first bracket 6 are connected by the centering rod 13, the receiving rack 9 will always remain stationary with the first bracket 6 when not subject to external force.

[0043] See also Fig.10 The elastic clamping assembly includes a U-shaped frame 17 fixedly arranged on the material receiving frame 9 and a screw rod 18 rotatably arranged on the U-shaped frame 17, and a moving rod 19 is slidably arranged on the material receiving frame 9; The moving rod 19 is threadedly matched with the screw rod 18, and a knob 20 is fixedly provided at the other end of the screw rod 18; A moving plate 21 is fixedly provided at one end of the moving rod 19, and the moving plate 21 is located inside the receiving rack 9. An arc-shaped clamping plate 23 is provided inside the receiving rack 9, and the arc-shaped clamping plate 23 is slidably matched with the moving plate 21 through a connecting column 22; A second spring 24 is sleeved on the outside of the connecting column 22 , and two ends of the second spring 24 are respectively against the moving plate 21 and the arc-shaped clamping plate 23 .

[0044] In this embodiment, after the connecting rod 3 falls into the receiving rack 9, when the movable plate 21 drives the arc clamping plate 23 to move toward the connecting rod 3 through the connecting column 22 and the second spring 24, the arc clamping plate 23 will cooperate with the receiving rack 9 to clamp and fix the connecting rod 3, wherein, due to the presence of the second spring 24, the fixing of the connecting rod 3 is elastic clamping; Because the moving rod 19 is slidably set on the material receiving frame 9, and the moving rod 19 is threadedly matched with the screw rod 18, the moving plate 21 is fixedly connected to the moving rod 19. Therefore, when the screw rod 18 is rotated by the knob 20, the moving rod 19 will drive the moving plate 21 to approach the connecting rod 3.

[0045] See also Figure 7 , Fig.10 The synchronization structure includes a No. 1 transmission wheel 25 fixedly arranged on the screw rod 18 and a No. 2 transmission wheel 26 fixedly arranged on the pin shaft 8, and the No. 1 transmission wheel 25 and the No. 2 transmission wheel 26 are connected by a belt 27.

[0046] In this embodiment, since the No. 1 transmission wheel 25 fixed on the screw rod 18 and the No. 2 transmission wheel 26 fixed on the pin shaft 8 are connected by the belt 27, the pin shaft 8 will rotate along with the rotation of the screw rod 18.

[0047] See also Figure 8 , Fig.14 The deflection assembly includes a sleeve 28 and a slide bar 29 slidably matched with the sleeve 28. A rotating shaft 30 is rotatably provided on the second bracket 7, and a deflection rod 31 is fixedly provided on the rotating shaft 30. 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 deflection rod 31; A third spring 32 is disposed inside the sleeve 28, and two ends of the third spring 32 abut against the other end of the slide bar 29 and the inner side wall of the other end of the sleeve 28 respectively; A matching rod 33 is fixedly provided on the material receiving rack 9. During the rotation of the deflection rod 31, the deflection rod 31 will cooperate with the matching rod 33 and drive the material receiving rack 9 to deflect. A limiting rod 34 corresponding to the deflection rod 31 is fixedly provided on the second bracket 7.

[0048] In this embodiment, due to the sliding fit between the sleeve 28 and the slide bar 29, one end of the sleeve 28 is rotatably connected to the second bracket 7, a rotating shaft 30 is rotatably provided on the second bracket 7, a deflection rod 31 is fixedly provided on the rotating shaft 30, one end of the slide bar 29 is rotatably connected to one end of the deflection rod 31, and two ends of the No. 3 spring 32 respectively abut against the other end of the slide bar 29 and the inner side wall of the other end of the sleeve 28. Therefore, when the rotating shaft 30 rotates, the deflection rod 31 will rotate accordingly. In this process, the sleeve 28 and the slide bar 29 will slide and fit and further compress the No. 3 spring 32. When the deflection rod 31, the sleeve 28 and the slide bar 29 rotate to the same straight line and then slightly deflect at an angle, the No. 3 spring 32 will instantly release the elastic force and drive the deflection rod 31 to rotate rapidly. Because the material receiving rack 9 is fixedly provided with a matching rod 33, and the matching rod 33 corresponds to the sway rod 31, during the rotation of the sway rod 31, the sway rod 31 will cooperate with the matching rod 33 and drive the material receiving rack 9 to sway, thereby causing the connecting rod 3 clamped in the material receiving rack 9 to sway, wherein the setting limit rod 34 is used to position the sway rod 31 to prevent the sway rod 31 from excessive rotation.

[0049] See also Figure 7 , Figure 8 , Fig.11 The transmission structure includes a connecting plate 35 and a rotating rod 36 rotatably arranged on the connecting plate 35, and the two ends of the connecting plate 35 are rotatably connected to the pin shaft 8 and the rotating shaft 30 respectively; A first bevel gear 37 and a second bevel gear 38 are fixedly disposed at both ends of the rotating rod 36 , a third bevel gear 39 meshing with the first bevel gear 37 is fixedly disposed on the pin shaft 8 , and a fourth bevel gear 40 meshing with the second bevel gear 38 is fixedly disposed on the rotating shaft 30 .

[0050] 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.

[0051] See also Figure 4 , Fig.11 The elastic locking assembly includes a sleeve 41 and a slide post 42 slidably matched with the sleeve 41, the sleeve 41 is slidably arranged on the second bracket 7 through an L-shaped plate 43, and one end of the slide post 42 is fixedly provided with an arc-shaped extrusion plate 44 matched with the string frame 2; A No. 4 spring 45 is disposed inside the sleeve 41, and two ends of the No. 4 spring 45 abut against the other end of the slide post 42 and the inner side wall of the sleeve 41 away from the end of the slide post 42 respectively; A disc 46 is fixedly provided at one end of the rotating shaft 30 , a roller 47 is fixedly provided at one end of the sleeve 41 close to the disc 46 , and the roller 47 fits with the disc 46 , and an oblique block 48 matching with the roller 47 is fixedly provided on one side of the disc 46 close to the sleeve 41 .

[0052] In this embodiment, since the arc-shaped extrusion plate 44 is fixedly arranged on the slide post 42 and the arc-shaped extrusion plate 44 cooperates with the string frame 2, when the slide post 42 drives the arc-shaped extrusion plate 44 to move toward the string frame 2 and abut against it, the friction between the arc-shaped extrusion plate 44 and the string frame 2 prevents the universal wheel 5 from moving, that is, the entire device remains stationary during the welding process. Because the sleeve 41 and the slide post 42 are slidably matched, and the sleeve 41 is slidably arranged on the L-shaped plate 43, the sleeve 41 can drive the slide post 42 to move toward the string frame 2; because a No. 4 spring 45 is arranged inside the sleeve 41, the two ends of the No. 4 spring 45 respectively abut against the other end of the slide post 42 and the inner side wall of the sleeve 41 away from the slide post 42, under the action of the No. 4 spring 45, the arc-shaped extrusion plate 44 and the string frame 2 are elastically extruded; Since a roller 47 is fixedly provided at one end of the sleeve 41, and the roller 47 is in contact with the disc 46, and an inclined block 48 cooperating with the roller 47 is fixedly provided at one side of the disc 46, when the shaft 30 rotates, the disc 46 will drive the inclined block 48 and the roller 47 to cooperate with each other, so that the sleeve 41 slides on the L-shaped plate 43 toward the string frame 2.
