Description

Technical Field

[0001] The present invention relates to the field of welding technology, and specifically to a steel structure truss welding device and process. Background Art

[0002] A steel structure truss is a structural system composed of straight bars, usually made of steel. Its characteristic is that the bars mainly bear axial tension or pressure. This structural form utilizes the geometric stability of triangles and forms a lightweight and high-strength support structure by combining multiple triangular units. Its welding quality directly affects the safety and service life of the structure.

[0003] Most steel structure trusses are composed of main pipes, secondary pipes and inclined pipes by welding. The finished products are mostly long strip structures with a square cross-section. To enhance their stability and for convenient installation, triangular reinforcement plates (mostly isosceles triangular structures with circular holes for fixation opened at the center point position) are mostly welded at the four top corners of the bottom of the finished product for reinforcement. When the existing welding equipment welds the reinforcement plates, the staff needs to hold the reinforcement plates while welding, and four groups of reinforcement plates are needed for each finished product, resulting in the staff constantly picking up new welding materials during the welding process, seriously affecting work efficiency.

An electric guide rail two for driving the vertical plate to move is provided in the horizontal plate. A card seat for placing the welding torch 3 is further provided on the receiving block 2. Among them, the electric guide rail one, the electric guide rail two, and the welding torch 3 all adopt existing publicly known technologies, and the welding torch 3 can be operated by hand;

[0053] A feeding mechanism. The feeding mechanism includes a placement cavity 7 for placing reinforcement plates. Four groups of placement cavities 7 are opened in the receiving block 2, and the placement cavities 7 completely penetrate the receiving block 2. A limiting component for restricting the distance between adjacent two reinforcement plates is further provided in the receiving block 2;

[0054] And a material transporting component for picking up the reinforcement plates in the placement cavity 7 and pressing the reinforcement plates to the welding area. The material transporting component is provided on the receiving block 2.

[0055] In an embodiment of the present invention, after the main pipe, the auxiliary pipe, and the inclined pipe are welded, the steel structure trusses to be reinforced are stacked together; preferably, the number of stacked steel structure trusses in the height direction is three groups; on the side of the receiving block 2 away from the material transporting assembly, a reinforcing plate is added to the placement cavity 7, and the limiting assembly can be used to place the reinforcing plates in the placement cavity 7 at equal intervals; after the reinforcing plate is placed in the placement cavity 7, the receiving block 2 is moved to the vicinity of the steel structure truss by using the walking wheels, and the height of the receiving block 2 is adjusted by using the electric guide rail 1, and the horizontal position of the receiving block 2 is adjusted by using the electric guide rail 2, so that the receiving block 2 can be located at the center position of the steel structure truss to be welded; the center position is the center position of the square structure at the bottom of the steel structure truss to be welded; the material transporting assembly picks up the reinforcing plate in the placement cavity 7 and presses the reinforcing plate onto the welding area, and the welding gun 3 is used to perform the welding treatment on the connection between the reinforcing plate and the steel structure truss to be welded; compared with the prior art, through the cooperative setting of the feeding mechanism and the material transporting assembly, the present invention avoids the problem that when the existing welding equipment welds the reinforcing plate, the staff needs to hold the reinforcing plate by hand while welding, and four groups of reinforcing plates are required for each finished product, resulting in the staff constantly picking up new welding materials during the welding process, which seriously affects the work efficiency.

[0056] In an embodiment of the present invention, please refer to Figures 1 - 9 , at least one group of the limiting assemblies is arranged in each placement cavity 7;

[0057] The limiting assembly includes:

[0058] Support rollers 10, the support rollers 10 are rotatably installed in the side wall of the receiving block 2, and multiple groups of support rollers 10 are provided;

[0059] A conveyor belt 11, the conveyor belt 11 is arranged on the support rollers 10, and multiple groups of limiting bars 12 are arranged at equal intervals on the conveyor belt 11; wherein the support rollers 10 and the conveyor belt 11 can be meshed and connected through a toothed structure;

[0060] And a blocking unit for controlling the moving direction of the reinforcing plate in the placement cavity 7;

[0061] The blocking unit includes:

[0062] A strip-shaped groove opened in the placement cavity 7, and a support shaft 13 is rotatably installed in the strip-shaped groove;

[0063] A limiting plate 15, the limiting plate 15 is fixedly installed on the support shaft 13;

[0064] A baffle 16 for blocking the limiting plate 15, the baffle 16 is fixedly installed in the strip-shaped groove;

[0065] and an elastic support piece 14 for pressing the limit plate 15 against the baffle 16. The elastic support piece 14 is fixedly installed in the strip-shaped groove, and the elastic support piece 14 is in sliding contact with the limit plate 15.

[0066] In this embodiment, during use, the reinforcement plate is added to the placement cavity 7 from the end far away from the material conveying component. After the reinforcement plate is pushed into the placement cavity 7, due to the blocking effect of the limit strip 12 on the reinforcement plate, the reinforcement plate can push the conveyor belt 11 to move. When the next group of limit strips 12 appears at the feeding port, the next group of reinforcement plates is put in and pushed towards the material conveying component side. At this time, the conveyor belt 11 will drive the previous group of reinforcement plates to move synchronously through the limit strips 12. By repeating the above steps, multiple groups of reinforcement plates can be added to the placement cavity 7, effectively avoiding the problem that workers need to pick up new welding materials multiple times during the welding process, effectively improving the welding efficiency. Using the blocking effect of the baffle 16 on the limit plate 15 can effectively prevent the reinforcement plate from moving in the reverse direction in the placement cavity 7, facilitating the operation of the material conveying component.

[0067] In an embodiment of the present invention, please refer to Figures 1 - 9 , the material conveying component includes:

[0068] A first telescopic member 4 disposed in the receiving block 2, and the first telescopic member 4 is located at the center of the receiving block 2;

[0069] A telescopic plate 6, and four groups of the telescopic plate 6 are fixedly installed on the telescopic end of the first telescopic member 4;

[0070] And a fixing unit disposed on the telescopic plate 6;

[0071] The fixing unit includes:

[0072] A control box 5 fixedly installed on the telescopic end of the telescopic plate 6, and an air cavity 23 is provided in the control box 5;

[0073] A first conduit 18 communicating with the air cavity 23;

[0074] A support tube 8 fixedly installed on the control box 5, and the support tube 8 is communicated with the air cavity 23 through a third conduit 22. A spray hole 19 is further provided at one end of the support tube 8 away from the control box 5;

[0075] A fixing airbag 9 for inserting into the circular hole of the fixing plate and supporting the fixing plate, the fixing airbag 9 is disposed on the support tube 8, and the fixing airbag 9 is communicated with the air cavity 23 through a second conduit 21;

[0076] A control component for blocking the air inlet end of the second conduit 21 or the air inlet end of the third conduit 22, and the control component is disposed on the control box 5;

[0077] and a second telescopic member 17 for driving the control box 5 to move in the telescopic direction of the telescopic plate 6, the second telescopic member 17 being fixedly installed on the telescopic end of the first telescopic member 4; wherein both the first telescopic member 4 and the second telescopic member 17 can be electric telescopic rods;

[0078] The control assembly includes:

[0079] A pressure rod 20 slidably installed in the control box 5, and a sealing plate 24 is provided at the end of the pressure rod 20;

[0080] and a spring 25 for elastically supporting the sealing plate 24, the spring 25 being arranged in the air chamber 23.

[0081] In this embodiment, during use, the first conduit 18 is connected to an external air source. The first telescopic member 4 can insert the support tube 8 into the round hole of the reinforcement plate by driving the telescopic plate 6 to move towards the accommodation block 2. When the spray holes 19 are exactly at both sides of the reinforcement plate (at this time, the pressure rod 20 is not pressed and the sealing plate 24 seals the air inlet end of the second conduit 21), the first conduit 18 introduces gas into the support tube 8 through the air chamber 23 and the third conduit 22 and sprays it out through the spray holes 19. The gas sprayed out through the spray holes 19 can blow and clean the right-angle sides (i.e., the sides to be welded) of the reinforcement plate to remove fine impurities, facilitating the improvement of welding quality. After cleaning, the first telescopic member 4 drives the telescopic plate 6 to continue moving towards the accommodation block 2 until the fixed airbag 9 is inserted into the round hole. The reinforcement plate can press the pressure rod 20, causing the pressure rod 20 to drive the sealing plate 24 to separate from the second conduit 21, so that the sealing plate 24 presses onto the third conduit 22. At this time, the gas in the air chamber 23 will enter the fixed airbag 9 through the second conduit 21, causing the fixed airbag 9 to expand. The expanded fixed airbag 9 can support and fix the reinforcement plate. When the control box 5 presses the reinforcement plate, the blocking unit can prevent the reinforcement plate from moving in the reverse direction. After fixation, the first telescopic member 4 will drive the telescopic plate 6 to move away from the accommodation block 2 and, in cooperation with the way the second telescopic member 17 drives the control box 5 to move, can press the reinforcement plate to the welding position; a visual sensor can be provided at the end of the first telescopic member 4, which is convenient for aligning the accommodation block 2 with the central position of the steel structure truss to be welded, and at the same time is convenient for pressing the reinforcement plate to the welding position. The visual sensor adopts the existing public technology, and a controller cooperating with the visual sensor can be provided in the device to facilitate controlling the working states of the first telescopic member 4, the second telescopic member 17, and the two electric guide rails (the first electric guide rail and the second electric guide rail) in combination with the visual signal.

[0082] Please refer to Figures 1 - 9, a steel structure truss welding process provided by an embodiment of the present invention uses the steel structure truss welding equipment as described above. This process includes the following steps:

[0083] Step 1: After the main pipe, auxiliary pipe, and inclined pipe are welded, stack the steel structure trusses that need to be reinforced together; preferably, the number of stacked steel structure trusses in the height direction is three groups;

[0084] Step 2: On the side of the receiving block 2 away from the material transporting component, add the reinforcing plate to the placement cavity 7, and use the limiting component to evenly place the reinforcing plates in the placement cavity 7 into the placement cavity 7;

[0085] Step 3: After the reinforcing plate is placed in the placement cavity 7, use the walking wheels to move the receiving block 2 near the steel structure truss, use the electric guide rail 1 to adjust the height of the receiving block 2, and use the electric guide rail 2 to adjust the horizontal position of the receiving block 2 so that the receiving block 2 can be at the central position of the steel structure truss to be welded; its central position is the central position of the square structure at the bottom of the steel structure truss to be welded;

[0086] Step 4: Use the material transporting component to pick up the reinforcing plate in the placement cavity 7 and press the reinforcing plate onto the welding area, and use the welding torch 3 to perform welding treatment on the connection between the reinforcing plate and the steel structure truss to be welded.

[0087] In the present invention, unless otherwise clearly defined and limited, terms such as "sliding", "rotating", "fixing", "provided with", etc. should be understood in a broad sense. For example, it can be a welded connection, a bolt connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined.
