Description

Technical Field

[0001] This invention relates to the field of positioning welding technology, and more specifically, to a welding device for insert-type steel supports for cast-in-place highway beams. Background Technology

[0002] The plate-type steel bracket positioning and fixing welding device used in the construction of cast-in-place highway beams is a core tool to ensure the safe and accurate installation of the steel bracket system. Its main purpose is to accurately position and ensure the geometric accuracy of the structure. After the steel bracket is positioned and fixed, a welding machine is used for welding.

[0003] Among the existing published documents, patent publication number CN214721865U discloses a support device for welding angle steel flanges of multiple specifications. This technology involves installing angle fixing blocks at multiple positions on a rotating welding frame through adjustable positioning holes. The lines connecting the centers of multiple adjustable positioning holes form a cross, and the intersection of these lines is the center point of the rotating welding frame. A dimension mark is provided on one side of each adjustable positioning hole, indicating the vertical distance from that location to the center point of the rotating welding frame. This allows the device to accommodate the welding of angle steel flanges of multiple specifications. However, this technology still has the following drawbacks.

[0004] During the welding process of plate-type steel supports for cast-in-place highway beams, the steel supports in the corner areas inside the cast-in-place highway beams are in various states, including inclined, vertical, and bent steel supports. There are numerous positioning and fixing points, and these positioning and fixing points are intertwined and complex, making it difficult to perform synchronous horizontal and longitudinal positioning and fixing at different points. This results in not only low efficiency in positioning and fixing the steel supports in different directions, but also poor stability of the positioning and welding. Summary of the Invention

[0013] An inclined arc block is fixedly installed on the top of the pressure strip. The inclined arc block is used to position and fix the inclined surface of the outer wall of the bent steel frame.

[0014] A bottom arc block is fixedly connected to the lower surface of the inclined arc block. The bottom arc block is used to be movably inserted into the bottom position of the outer wall of the bent steel frame. A groove plate is fixedly connected to the outer wall of the welded positioning frame, and a sliding rod is fixedly connected to the inner wall of the groove plate.

[0015] The inner walls of the sleeve and the sleeve rod are slidably connected to the slide rod, and the slide rod passes through the sleeve and the bent steel frame.

[0016] In a preferred embodiment, the upper surface of the inclined arc block is an inclined surface, and the vertical cross-sectional shape of the bottom arc block is an arc.

[0017] In a preferred embodiment, the longitudinal linkage mechanism includes:

[0018] An elastic pull rope is fixedly connected at its bottom end to the upper surface of the linkage block. A stepped plate is slidably connected to the outer wall of the elastic pull rope, and the stepped plate is fixedly connected to the welded positioning frame.

[0019] An inclined pressure strip is fixedly located at the top of the elastic pull rope. A vertical pressure strip is fixedly connected to one end of the inclined pressure strip. A spacer block is provided on one side of the vertical pressure strip. The spacer block is used to be inserted into the gap between the vertical steel frame and the inclined steel frame. An inclined arc plate is fixedly connected to one side of the spacer block. The inclined arc plate is fixedly connected to the inclined pressure strip.

[0020] The diagonal support strip is fixedly connected to the other end of the diagonal pressure strip.

[0021] In a preferred embodiment, a sleeve block is fixedly connected to one side of the inclined pressure strip, and a guide rod that is slidably connected passes through the inner wall of the sleeve block. The guide rod is fixedly connected to the welding positioning frame.

[0022] A spring sheet is fixedly connected to one side of the socket block, and a support block is fixedly installed at one end of the spring sheet, and the support block is fixedly connected to the welding positioning frame.

[0023] In a preferred embodiment, the upper surfaces of the inclined arc plate and the inclined support are both inclined surfaces, and an arc-shaped block is slidably installed on the outer wall of the elastic pull rope at a position on one side of the step plate. The lower surface of the arc-shaped block is fixedly connected to the welding positioning frame.

[0024] In a preferred embodiment, a controller is installed on the upper surface of the welding positioning frame and near its central position, and a storage battery is fixedly connected to one side of the outer wall of the controller;

[0025] Both the electric cylinder and the pressure sensor are electrically connected to the controller, which is fixedly connected to the battery.

[0026] The technical effects and advantages of this invention are as follows:

[0027] This invention utilizes a staggered synchronous positioning mechanism. By activating the output end of the electric cylinder to push the pressure sensor, the pressure plate moves downward, causing the sleeve rod to move to the right along the guide rod. The sleeve rod drives the connecting strip, thereby causing the inclined pressure block to laterally press the inclined surface of the outer wall of the inclined steel frame. At the same time, the vertical pressure plate laterally presses the outer wall of the vertical steel frame, achieving lateral staggered synchronous positioning and fixing of the inclined and vertical steel frames. This results in higher welding efficiency for the positioning and fixing of the inclined and vertical steel frames in different directions, and better weld strength after positioning and fixing.

[0028] This invention utilizes a misaligned linkage component. The downward movement of the pressure plate causes the sleeve pressure column to move to the left, which in turn pushes the pressure strip to move to the left and tilts and squeezes the inclined surface of the outer wall of the bent steel frame. The inclined arc block drives the bottom arc block to move to the left, allowing the bottom arc block to contact the bottom of the outer wall of the bent steel frame. This allows the inclined arc block and the bottom arc block to be misaligned to accurately position and fix the side and bottom of the outer wall of the bent steel frame. For bent steel frames in different directions, this invention not only makes the positioning and fixing welding process more efficient, but also significantly shortens the welding preparation time. Furthermore, it significantly improves the positioning firmness, providing a stable foundation for subsequent welding and ensuring welding quality.

[0029] This invention utilizes a longitudinal linkage mechanism. When the pressure plate moves downward, it causes the linkage block to move downward synchronously. The elastic pull rope drives the inclined pressure strip forward. The spacer block is inserted into the angled gap between the vertical steel frame and the inclined steel frame. The vertical pressure strip is longitudinally pressed against the outer wall of the vertical steel frame to longitudinally position and fix the vertical steel frame. The inclined arc plate is inclinedly pressed against the outer wall of the inclined steel frame to achieve inclined longitudinal positioning and fixation of the inclined steel frame. The inclined support bar is inclinedly pressed against the inclined surface of the outer wall of the bent steel frame. The inclined steel frame, the vertical steel frame, and the bent steel frame are longitudinally synchronously positioned and fixed by welding. Even if the positioning points are intersecting and complex, synchronous positioning and fixing welding can be quickly achieved, and the firmness of the positioning and fixing welding is significantly improved.

[0030] In summary, through the interaction of the above-mentioned multiple functions, firstly, the inclined pressure block laterally compresses the inclined surface of the outer wall of the inclined steel frame, while the vertical pressure plate laterally compresses the outer wall of the vertical steel frame, thus achieving lateral misalignment and synchronous positioning and fixation of the inclined and vertical steel frames. Simultaneously, the inclined arc block and bottom arc block can misalign and precisely position and fix the sides and bottom of the outer wall of the bent steel frame, while also achieving longitudinal synchronous positioning and welding between the inclined, vertical, and bent steel frames. Therefore, even if the positioning and welding positions of the inclined, vertical, and bent steel frames are complex and intertwined, lateral and longitudinal misalignment and synchronous positioning and welding can be quickly achieved, resulting in higher efficiency in positioning and welding of the inclined, vertical, and bent steel frames in different directions, and better weld strength after positioning and fixing.

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figure 1 - Figure 8 The welding device for the insert-type steel bracket of the cast-in-place highway beam shown is equipped with a staggered synchronous positioning mechanism, a staggered linkage component, and a longitudinal linkage mechanism. The arrangement of each mechanism and component can quickly achieve horizontal and longitudinal staggered synchronous positioning and fixing welding even if the positioning and welding positions of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 are complex and intertwined. This makes the positioning and fixing welding efficiency of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 in different directions higher, and the weld after positioning and fixing is more robust. The specific structural settings of each mechanism and component are as follows.

[0042] In this embodiment, as Figure 1 - Figure 2As shown, the lower surface of the pressure sensor 3 is provided with a misaligned synchronous positioning mechanism, which includes: a pressure groove plate 4, fixedly connected to the bottom end of the pressure sensor 3; a sleeve rod 5 slidably connected to one inclined surface of the inner wall of the pressure groove plate 4; a connecting strip 6 fixedly connected to one end of the sleeve rod 5; an inclined pressure block 7, fixedly located at one end of the connecting strip 6; a vertical pressure plate 8 fixedly connected to the other end of the connecting strip 6; an inclined steel frame 9, located on one side of the inclined pressure block 7; a vertical steel frame 10 on one side of the vertical pressure plate 8; a bent steel frame 15 on one side of the vertical steel frame 10; a linkage block 16 fixedly connected to one side of the outer wall of the pressure groove plate 4; and a longitudinal linkage mechanism installed at the top of the linkage block 16. The longitudinal linkage mechanism is used to synchronously perform longitudinal positioning and fixing of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15. The sensing end of the pressure sensor 3 is fixedly connected to the output end of the electric cylinder 2, and the vertical cross-section of the sleeve rod 5 is circular. The outer wall of the sleeve rod 5 and the inner wall of the pressure groove plate 4 are both smooth surfaces, the upper surface of the inclined pressure block 7 is an inclined surface, and the upper surface of the vertical pressure plate 8 is a horizontal surface. This allows the output end of the electric cylinder 2 to push the pressure sensor 3 downward, causing the pressure sensor 3 and the pressure groove plate 4 to drive the sleeve rod 5 to press and move to the right. The sleeve rod 5 then drives the connecting strip 6 to move to the right, while the inclined pressure block 7, in its inclined state, presses laterally against the inclined surface of the outer wall of the inclined steel frame 9. The vertical pressure plate 8 presses laterally against the outer wall of the vertical steel frame 10, achieving lateral misalignment and synchronous positioning and fixing of the inclined steel frame 9 and the vertical steel frame 10. This lateral misalignment and synchronous positioning welding is faster and more stable.

[0043] In this embodiment, as Figure 2 - Figure 4 As shown, a misalignment linkage assembly is fixedly installed on the inclined surface of the inner wall of the pressure plate 4. The misalignment linkage assembly includes: a pressure column 11, which is slidably installed on the inclined surface of the inner wall of the pressure plate 4, and a pressure strip 12 is fixedly connected to one end of the pressure column 11; an inclined arc block 13, which is fixedly installed on the top of the pressure strip 12, and is used to position and fix the inclined surface of the outer wall of the bent steel frame 15; and a bottom arc block 14, which is fixedly connected to the lower surface of the inclined arc block 13, and is used to move and insert into the bottom position of the outer wall of the bent steel frame 15. A groove plate 31 is fixedly connected to the outer wall of the welding positioning frame 1, and a sliding rod 32 is fixedly connected to the inner wall of the groove plate 31. The inner walls of the pressure column 11 and the sleeve rod 5 are slidably connected to the sliding rod 32, and the sliding rod 32 passes through the pressure column 11 and the bent steel frame 15. The upper surface of the inclined arc block 13 is an inclined surface, and the vertical cross-section of the bottom arc block 14 is an arc shape. So that the downward movement of the pressure plate 4 will drive the sleeve pressure column 11 to move to the left, and the sleeve pressure column 11 will drive the pressure strip 12 to move to the left. In this way, the inclined arc block 13 is pressed on the inclined surface of the outer wall of the bent steel frame 15 in an inclined state, while the bottom arc block 14 contacts the bottom position of the outer wall of the bent steel frame 15. This allows the inclined arc block 13 and the bottom arc block 14 to be misaligned to position and fix the outer side and bottom of the outer wall of the bent steel frame 15. This not only makes the positioning and fixing welding more efficient, but also more stable.

[0044] In this embodiment, as Figure 5 - Figure 7 As shown, the longitudinal linkage mechanism includes: an elastic pull rope 17, the bottom end of which is fixedly connected to the upper surface of the linkage block 16, and a step plate 18 is slidably connected to the outer wall of the elastic pull rope 17, the step plate 18 being fixedly connected to the welded positioning frame 1; an inclined pressure strip 19, fixedly located at the top of the elastic pull rope 17, a vertical pressure strip 20 being fixedly connected to one end of the inclined pressure strip 19, a spacer block 21 being provided on one side of the vertical pressure strip 20, the spacer block 21 being used to insert into the gap between the vertical steel frame 10 and the inclined steel frame 9, and an inclined arc plate 22 being fixedly connected to one side of the spacer block 21, the inclined arc plate 22 being fixedly connected to the inclined pressure strip 19; and an inclined support strip 23, fixedly connected to the other end of the inclined pressure strip 19. A sleeve block 24 is fixedly connected to one side of the inclined pressure strip 19. A guide rod 27 with sliding connection passes through the inner wall of the sleeve block 24. The guide rod 27 is fixedly connected to the welding positioning frame 1. A spring piece 25 is fixedly connected to one side of the sleeve block 24. A support block 26 is fixedly installed at one end of the spring piece 25. The support block 26 is fixedly connected to the welding positioning frame 1. So that when the pressure plate 4 moves down, it will drive the linkage block 16 to move down synchronously, so that the elastic pull rope 17 slides along the outer wall of the arc block 28. The inclined pressure bar 19 starts to drive the vertical pressure bar 20 to press longitudinally on the outer wall of the vertical steel frame 10, and fix the vertical steel frame 10 longitudinally. The inclined pressure bar 19 drives the inclined arc plate 22 to move the spacer block 21 forward and insert it into the angle gap between the vertical steel frame 10 and the inclined steel frame 9. The inclined arc plate 22 is inclined and longitudinally pressed on the outer wall of the inclined steel frame 9. The inclined pressure bar 19 drives the inclined support bar 23 to move forward. The inclined support bar 23 is inclined and pressed on the inclined surface of the outer wall of the bent steel frame 15, and fixes the outer wall of the bent steel frame 15 in an inclined position. At the same time, the inclined pressure bar 19 drives the socket block 24 to move forward, ensuring that the socket block 24 moves forward along the outer wall of the guide rod 27. The support block 26 supports the spring piece 25, and the spring piece 25 provides elastic tension operation to the socket block 24. The longitudinal synchronous positioning and fixing of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 not only makes the positioning and fixing welding more efficient, but also makes the welding more stable.

[0045] In this embodiment, as Figure 6 As shown, the upper surfaces of the inclined arc plate 22 and the inclined support 23 are both inclined surfaces. An arc-shaped block 28 is slidably installed on the outer wall of the elastic pull rope 17 and located on one side of the step plate 18. The lower surface of the arc-shaped block 28 is fixedly connected to the welded positioning frame 1. This allows the elastic pull rope 17 to slide along the outer wall of the arc-shaped block 28, reducing wear on the outer wall of the elastic pull rope 17.

[0046] In this embodiment, as Figure 8As shown, a controller 29 is installed on the upper surface of the welding positioning frame 1 near its central position. A battery 30 is fixedly connected to one side of the outer wall of the controller 29. The electric cylinder 2 and the pressure sensor 3 are both electrically connected to the controller 29, and the controller 29 is fixedly connected to the battery 30. This allows the controller 29 to be powered by the battery 30, enabling the controller 29 to start the electric cylinder 2. The electric cylinder 2 is then shut off by the controller 29 when the pressure value sensed by the pressure sensor 3 matches the pressure value set by the controller 29.

[0047] The working principle of the welding device for the insert-plate type steel bracket for cast-in-place highway beams of the present invention is as follows:

[0048] First, when the present invention is installed, the bottom ends of the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 are all pre-embedded and fixed with the concrete of the highway cast-in-place beam. Then, the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 need to be contact welded. Then, the welding positioning frame 1 is placed in the highway cast-in-place beam trough, and the lower surface of the welding positioning frame 1 is placed at the bottom of the inner wall of the highway cast-in-place beam trough. The welding positioning frame 1 is positioned at the outer wall of the vertical steel frame 10 and the outer wall of the inclined steel frame 9, and the lower surface of the welding positioning frame 1 is attached to the outer wall of the bent steel frame 15.

[0049] Secondly, during the staggered synchronous positioning welding of this invention, the battery 30 powers the controller 29, which in turn activates the electric cylinder 2. The output of the electric cylinder 2 pushes the pressure sensor 3 downward, which in turn moves the pressure plate 4 downward. The pressure plate 4 then moves the sleeve rod 5 to the right, guiding it to the right along the outer wall of the slide rod 32. Simultaneously, the welding positioning frame 1 supports the groove plate 31, which in turn supports the slide rod 32. The sleeve rod 5 moves steadily to the right, causing the connecting strip 6 to move to the right. The connecting strip 6 then moves the inclined pressure block 7 to the right, which laterally presses against the inclined surface of the outer wall of the inclined steel frame 9 while in an inclined state. At the same time, the connecting strip 6 moves the vertical pressure plate 8 to the right, which laterally presses against the outer wall of the vertical steel frame 10. This achieves lateral staggered synchronous positioning and fixation of the inclined steel frame 9 and the vertical steel frame 10.

[0050] Simultaneously, when the present invention performs misalignment linkage, the downward movement of the pressure plate 4 will drive the sleeve pressure column 11 to move to the left. The sleeve pressure column 11 moves to the left along the outer wall of the slide rod 32, and at the same time, the sleeve pressure column 11 drives the pressure strip 12 to move to the left. The pressure strip 12 causes the inclined arc block 13 to move to the left. The inclined arc block 13 presses against the inclined surface of the outer wall of the bent steel frame 15 in an inclined state. At the same time, the inclined arc block 13 drives the bottom arc block 14 to move to the left. The bottom arc block 14 contacts the bottom position of the outer wall of the bent steel frame 15. In this way, the inclined arc block 13 and the bottom arc block 14 can be misaligned to position and fix the outer side and bottom of the outer wall of the bent steel frame 15.

[0051] Simultaneously, during longitudinal linkage, when the pressure plate 4 moves downward, it causes the linkage block 16 to move downward synchronously. The linkage block 16 pulls the bottom end of the elastic rope 17 downward, causing the elastic rope 17 to slide along the outer wall of the arc-shaped block 28 and move forward along the outer wall of the step plate 18. This causes the elastic rope 17 to move the inclined pressure strip 19 forward, which in turn causes the vertical pressure strip 20 to longitudinally press against the outer wall of the vertical steel frame 10, thus longitudinally positioning and fixing the vertical steel frame 10. Furthermore, the inclined pressure strip 19 causes the inclined arc plate 22 to move the spacer block 21 forward, and the spacer block 21 is guided and inserted into the angled gap between the vertical steel frame 10 and the inclined steel frame 9. At the same time, the inclined arc plate 22 longitudinally presses against the outer wall of the inclined steel frame 9, achieving inclined longitudinal positioning and fixing of the inclined steel frame 9. At the same time, the inclined pressure strip 19 drives the inclined support strip 23 to move forward. The inclined support strip 23 is inclined and pressed against the inclined surface of the outer wall of the bent steel frame 15. In this way, the inclined support strip 23 is inclined and fixed to the outer wall of the bent steel frame 15. At the same time, the vertical steel frame 10, the inclined steel frame 9, and the bent steel frame 15 are all fixed to the side of the step plate 18.

[0052] Simultaneously, the inclined pressure bar 19 drives the sleeve block 24 to move forward. The sleeve block 24 moves forward along the outer wall of the guide rod 27, and is supported by the support block 26 through the welding positioning frame 1. The support block 26 supports the spring piece 25, and the spring piece 25 provides elastic tension to the sleeve block 24. At the same time, the elastic pull rope 17 can also deform and stretch itself, thus ensuring that the linkage block 16 moves down, so that the vertical pressure bar 20, the inclined arc plate 22, and the inclined support bar 23 move forward longitudinally in sync. When the pressure value sensed by the pressure sensor 3 is the same as the pressure value set by the controller 29, the electric cylinder 2 is shut off by the controller 29. In this way, the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 are simultaneously positioned and fixed in a horizontally staggered manner, and can also be positioned and fixed in a longitudinally synchronized manner. Then, the edge welding is performed on the connection between the inclined steel frame 9, the vertical steel frame 10, and the bent steel frame 15 using a welding torch.
