Description

Technical Field

[0001] This application relates to the field of corrugated steel web processing technology, specifically to an assembly platform for corrugated steel webs. Background Technology

[0002] Corrugated steel webs are thin steel plates with periodic waveforms, commonly used as structural components in bridges, buildings, and other engineering projects. Their unique waveform design (common shapes include sine waves, trapezoidal waves, and rectangular waves) allows them to provide excellent shear resistance and structural stability while remaining lightweight, making them a significant innovative material in modern engineering to replace traditional concrete or flat steel webs. Corrugated steel webs are typically prefabricated in factories with high dimensional accuracy, and can be quickly assembled on-site using bolts or welding, shortening the construction cycle.

[0003] During the processing of corrugated steel web plates, the main body plate must first be placed stably on a dedicated tooling platform to ensure accurate positioning and a level surface. Then, the flange plates to be connected are hoisted to both sides of the main body plate, and their relative positions are adjusted to align the connecting ends, ensuring that the assembly dimensional tolerances meet design and process requirements. After accurate positioning, temporary spot welding is performed at several points along the connection between the flange plates and the main body plate to form a preliminary assembled component. Finally, using lifting equipment, the temporarily fixed assembled component is transferred to a specialized welding station. Following established welding procedures, continuous welding is performed on the weld between the flange plates and the main body plate, ultimately completing the overall assembly and welding process of the corrugated steel web plate.

[0004] like Figure 1 As shown, the existing assembly platform mainly consists of a bracket 1 and a pressure frame 2, with support frames 11 on both sides of the bracket 1. The bracket 1 bears the load of the corrugated steel web main plate, while the support frames 11 support the flange plates. After multiple corrugated steel web main plates are placed on the bracket 1 and their positions are aligned, they are pressed and fixed by the pressure frame 2. Then, the flange plates are placed on the support frames 11, ensuring accurate alignment with the main plates, allowing workers to operate welding equipment for welding operations.

[0005] Regarding the aforementioned technical solution, because the flange plate's center of gravity is biased to one side while its bottom support area is located on the other side, the vertical line of the center of gravity does not fall within the bottom support area. This imbalance of forces generates a tipping moment, making the flange plate prone to tilting after placement. Therefore, during assembly, operators need to continuously support it to keep the flange plate perpendicular to the main plate. However, the flange plate has a significant weight, and prolonged support can easily lead to operator fatigue, resulting in high labor intensity and difficulty in consistently maintaining the alignment accuracy of the two plates, which may ultimately affect the welding quality of the product. Summary of the Invention

[0006] In view of this, this application provides an assembly platform for corrugated steel web plates, which is mainly used to solve the problem that when using the assembly platform for corrugated steel web plates, the flange plates on both sides of the main plate rely on manual support for positioning, which results in high labor intensity and poor alignment accuracy.

[0007] To address the aforementioned technical problems, this application provides an assembly platform for corrugated steel web plates, comprising a bracket and a pressure frame. A hanging plate is provided on the top of the pressure frame. The pressure frame and bracket cooperate to press and fix the main body plate of the corrugated steel web plate. Multiple rotating shafts are rotatably connected to the bracket. Each rotating shaft has a lead screw with opposite thread directions at both ends. Clamping components are mounted on the lead screws to support the flange plates and maintain their stability during movement. A driving component is also provided on the bracket to drive the rotating shafts to rotate, thereby causing the clamping components at both ends to move synchronously towards or away from each other. A support rod connects the clamping components to the bracket to enhance the stability of the clamping components during movement. Hydraulic cylinders are provided on both sides of the bracket, and transverse movable holes are provided on both sides of the pressure frame. A transverse plate is installed inside each transverse movable hole. A limiting component is also provided on the pressure frame to limit the movement of the transverse plate.

[0008] By adopting the above technical solution, after the main body plate is placed on the bracket and adjusted to the preset position, the pressure frame falls from above the bracket to press and fix the main body plate. Subsequently, the flange plates to be assembled are placed on the clamping components on both sides of the rotating shaft, ensuring that the flange plates remain perpendicular to the main body plate. The drive component drives the rotating shaft to drive the lead screw to rotate, causing the two clamping components to move synchronously towards each other, moving the flange plates on both sides to the position of the main body plate and achieving precise alignment. At this point, the splicing process of each component of the corrugated steel web can be completed, and spot welding can be performed at the joints to form a preliminary assembled component. Compared with traditional assembly processes, this platform can replace manual labor for the movement and positioning of flange plates, significantly reducing the labor intensity of operators, while ensuring the stability of the flange plates during assembly, effectively guaranteeing the forming quality of the corrugated steel web.

[0009] Optionally, the bottom of the pressure frame is provided with multiple sets of positioning components arranged in a straight line. Each set of positioning components includes a first guide plate and a second guide plate, which are arranged in a figure-eight shape.

[0010] By adopting the above technical solution, after the flange plates are fixed to the clamping assembly and before the pressure frame falls, the clamping assembly drives the two flange plates to move synchronously towards each other, using the flange plates to automatically correct the skewed main plate and restore it to its correct position. Subsequently, the flange plates move synchronously away from each other, disengaging from the main plate. During the downward movement of the pressure frame, the main plate is guided to the designated area on the bracket and precisely positioned through the coordinated action of the first and second guide plates. Then, the two flange plates, driven by the clamping assembly, re-contact and press firmly against the main plate. This method eliminates the need for manual adjustment of the main plate position, significantly improving assembly efficiency while ensuring the production quality of the corrugated steel web.

[0011] Optionally, the clamping assembly at one end of the rotating shaft includes a first movable arm, on which two first clamping plates are symmetrically fixedly disposed on both sides; the clamping assembly at the other end of the rotating shaft includes a second movable arm, on which insert rods are slidably sleeved at both ends, and second clamping plates are fixedly connected to the top ends of the insert rods; a linkage is provided between the second movable arm and the two insert rods to drive the two second clamping plates to move synchronously towards or away from each other.

[0012] By adopting the above technical solution, the two second clamping plates on the second movable arm can move synchronously towards or away from each other, avoiding interference with the picking and placing of flanges with different structures, making the picking and placing of flanges more convenient and labor-saving, and significantly improving the versatility and applicability of the platform.

[0013] Optionally, the linkage includes a lifting frame disposed below the second movable arm, a limiting block is provided on the side of the insert rod away from the second movable arm, the limiting block is provided with an inclined surface that slopes outward from top to bottom, a connecting rod is movably sleeved in the middle of the second movable arm, the bottom end of the connecting rod is fixedly connected to the lifting frame, a touch plate is fixedly connected to the top end of the connecting rod, and a spring is fixedly connected between the second movable arm and the insert rod.

[0014] Optionally, the upper surface of the second movable arm is provided with a groove that matches the touch plate.

[0015] By adopting the above technical solution, under the pressure of the flange plate, the contact plate moves downward and retracts into the groove, so that the bottom of the flange plate finally maintains contact with the upper surface of the second movable arm. This structure increases the effective contact area between the two, thereby improving the stability of the flange plate placement.

[0016] Optionally, rollers are rotatably connected to the top of both sides of the lifting frame.

[0017] By adopting the above technical solution, and replacing the direct contact between the lifting frame and the limiting block with rollers, the original sliding friction can be transformed into rolling friction, thereby significantly reducing the moving resistance of the lifting frame and ensuring its smoother operation.

[0018] Optionally, the limiting component includes a connecting plate and a connecting arm mounted on the pressure frame. The horizontal plate has a mounting hole, and a connecting shaft is inserted into the mounting hole. The connecting shaft is fixedly connected to the connecting plate. An insert shaft is fixedly connected to one side of the bottom of the connecting plate. The pressure frame and the connecting arm are respectively provided with a second insert hole and a first insert hole that are adapted to the insert shaft.

[0019] Optionally, a bottom shaft is fixedly connected to the bottom end of the connecting shaft. The bottom shaft has a circular cross-section, while the connecting shaft has a polygonal cross-section.

[0020] By adopting the above technical solution, once the connecting shaft is inserted into the corresponding mounting hole, its angle relative to the horizontal plate is fixed, thereby effectively enhancing the stability of the horizontal plate during operation. If it is necessary to adjust the angle of the connecting shaft, the connecting shaft can be lifted upwards first, so that the bottom shaft rises into the mounting hole. At this time, the connecting shaft can be rotated to adjust the position of the inserted shaft.

[0021] Optionally, guide ribs and positioning ribs are respectively provided at both ends of the bracket and the pressure frame, and the guide ribs and positioning ribs are compatible with each other.

[0022] By adopting the above technical solution, the positioning ribs and guide ribs cooperate with each other during the downward movement of the pressure frame, which can effectively prevent the pressure frame from shifting position, thereby improving its movement stability.

[0023] Optionally, the drive assembly includes a motor mounted on a bracket and a first gear mounted on a rotating shaft, with a second gear disposed on the output shaft of the motor, and the first and second gears meshing together.

[0024] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0025] 1. By employing a clamping mechanism capable of moving in opposite directions to replace manual operation, the flange plates are transferred and positioned. This not only significantly reduces the labor intensity of workers but also ensures the accuracy of alignment between the flange plates and the corrugated web body plate, thereby guaranteeing the assembly quality of the corrugated web plate. Simultaneously, this assembly platform can perform positioning and assembly operations on multiple flange plates at the same time, which is beneficial to improving work efficiency.

[0026] 2. Through the coordinated action of the flange plates, clamping mechanism, pressure frame, and guide plate, the skewed main plate can be automatically corrected by the opposing movement of the two flange plates before the corrugated steel web main plate is clamped. Subsequently, during the downward movement of the pressure frame, the main plate is pushed to the preset position by the guide plate, thus maintaining precise alignment. Compared with traditional assembly methods, this method eliminates the need for manual adjustment of the main plate position before component assembly, saving adjustment time and improving assembly efficiency.

[0027] 3. Through the cooperation of the second movable arm, the insertion rod, the second clamping plate and the linkage, while ensuring convenient disassembly and assembly, it is possible to clamp flanges with different structures, thereby increasing the versatility of the platform and expanding its application range.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will be combined with the embodiments of this application. Figures 2-8The technical solutions of the embodiments of this application are clearly and completely described herein. All other embodiments obtained by those skilled in the art based on the described embodiments are within the scope of protection of this application.

[0038] Reference Figure 2 , Figure 3 and Figure 4 This embodiment provides an assembly platform for corrugated steel web plates, including a bracket 1, a pressure frame 2, a clamping mechanism, a driving mechanism, and a support mechanism. Hydraulic cylinders 12 are provided at both ends of the bracket 1. The bracket 1 is used to support the main body plate of the corrugated steel web and can support multiple plates at the same time. The top of the pressure frame 2 is provided with a hanging plate 21. The trolley drives the pressure frame 2 to move through the hanging plate 21, so that it can move above the bracket 1 and cooperate with the bracket 1 to achieve the pressing and fixing of the main body plate of the corrugated steel web. There are three sets of clamping mechanisms, which are arranged linearly on the bracket 1. Each set of clamping mechanisms includes two clamping components, which are used to transfer the flange plate and position it. The number of driving mechanisms is adapted to the number of clamping mechanisms. The driving mechanisms are provided on the bracket 1 and are used to drive the clamping components to move synchronously in opposite directions or in opposite directions. There are two sets of support mechanisms, which are symmetrically arranged at both ends of the pressure frame 2. They will not interfere with the movement of the pressure frame 2 when it moves down. After the pressure frame 2 has moved down, it can be moved and cooperate with the hydraulic cylinders 12 to press and fix the main body plate of the corrugated steel web on the bracket 1. In this embodiment, the number of clamping mechanisms and driving mechanisms is adapted to the number of corrugated steel web body plates that the bracket 1 can support.

[0039] Among them, reference Figure 2 , Figure 3 and Figure 5Each clamping mechanism includes two clamping assemblies, which are symmetrically arranged on both sides of the bracket 1. One clamping assembly includes a first movable arm 31 and two first clamping plates 311. The two first clamping plates 311 are symmetrically distributed on both sides of the top of the first movable arm 31 and are fixedly connected to the first movable arm 31. The other clamping assembly includes a second movable arm 32, two insert rods 321, two second clamping plates 322, and a linkage. There are two insert rods 321 and two second clamping plates 322. The insert rods 321 have an "L" shape. The second clamping plates 322 are fixedly connected to the top of the insert rods 321. The two insert rods 321 are slidably inserted into the two ends of the second movable arm 32. The linkage is located between the second movable arm 32 and the two insert rods 321 and is used to drive the two second clamping plates 322 to move synchronously towards or away from each other. The linkage includes a limiting block 323, a lifting frame 324, a contact plate 326, a spring 327, and a connecting rod 329. The lifting frame 324 is located below the second movable arm 32. The limiting block 323 is fixedly connected to the side of the insert rod 321 away from the second movable arm 32, and the limiting block 323 has an inclined surface that slopes outward from top to bottom, enabling it to drive and cooperate with the lifting frame 324. There are two connecting rods 329, with their bottom ends fixedly connected to the lifting frame 324 and their top ends fixedly connected to the contact plate 326. Both connecting rods 329 pass through the second movable arm 32. There are two springs 327, which are respectively located between the corresponding second movable arm 32 and the insert rod 321. In this embodiment, under the action of the spring 327, the distance between the two second clamping plates 322 is greater than the overall length of the flange plate.

[0040] Corrugated steel webs typically consist of a main plate and two flange plates. One flange plate has several bolts, while the other flange plate has two different structures: one is a vertical plate combined with multiple perforated L-shaped plates, and the other is a vertical plate combined with two perforated transverse plates.

[0041] To enable both types of flanges with different structures to be transferred and positioned via the clamping mechanism, this solution employs two different clamping components working together: for flanges with bolts, they are placed between two first clamping plates 311 for support and fixation; for flanges with two different structures, they are placed between second clamping plates 322. When the moving flange contacts the contact plate 326, the contact plate 326, under the influence of the flange's gravity, will drive the connecting rod 329 to cause the lifting frame 324 to move downwards. The lifting frame 324, by pressing the inclined surface of the limiting block 323, causes the two second clamping plates 322 to move towards each other simultaneously, thus locking in the middle of the flange and achieving support and fixation. When the assembled corrugated steel web needs to be removed from the bracket 1, as the corrugated steel web moves upwards, the spring 327, under the action of restoring force, drives the corresponding insertion rod 321 to reset, increasing the distance between the two second clamping plates 322 for smooth removal. Compared to traditional processing methods, this method not only reduces the labor intensity of workers, but also ensures the alignment accuracy between the flange plate and the main plate, thereby ensuring the assembly quality of the corrugated steel web plate.

[0042] Among them, reference Figure 2 and Figure 3 The drive mechanism includes a rotating shaft 3, lead screws 33, support rods 37, and a drive assembly. There are two lead screws 33, fixedly connected to both ends of the rotating shaft 3, with opposite thread directions. The two lead screws 33 are threadedly connected to the first movable arm 31 and the second movable arm 32, respectively. There are four support rods 37, symmetrically distributed in pairs on both sides of the rotating shaft 3. The support rods 37 are slidably sleeved inside the bracket 1 and fixedly connected to the first movable arm 31 and the second movable arm 32, respectively, to enhance the stability of the first and second movable arms 31 during movement. The drive assembly drives the rotating shaft 3 to rotate. The drive assembly includes a first gear 34, a motor 35, and a second gear 36. The motor 35 is mounted on the bracket 1, and the second gear 36 is mounted on the output shaft of the motor 35. The first gear 34 is fixedly mounted in the middle of the rotating shaft 3, and the first gear 34 and the second gear 36 are meshed together. In practical use, a sleeve can be installed on the bracket 1, and the support rod 37 is movably inserted into the two ends of the sleeve, which can increase the contact area between the support rod 37 and the bracket 1, thereby improving its stability.

[0043] The output shaft of motor 35 drives the second gear 36 to rotate the first gear 34. The first gear 34 drives the rotating shaft 3 to rotate the lead screw 33 synchronously, thereby causing the first movable arm 31 and the second movable arm 32 to move in opposite directions at the same time, replacing manual transfer of the flange plate and greatly reducing the labor intensity of workers.

[0044] Among them, reference Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 The support mechanism includes a transverse movable hole 4, a horizontal plate 41, and a limiting component. The transverse movable hole 4 is formed on the pressure frame 2, and the horizontal plate 41 is movably fitted inside the transverse movable hole 4. The limiting component is used to limit the horizontal plate 41 to keep its position stable. The limiting component includes a mounting hole 411, a connecting plate 42, a connecting shaft 421, an insert shaft 423, a connecting arm 43, a first insert hole 44, and a second insert hole 45. The connecting arm 43 is fixedly connected to the pressure frame 2, the mounting hole 411 is formed on the horizontal plate 41, and the connecting shaft 421 and the insert shaft 423 are respectively fixedly connected to the bottom sides of the connecting plate 42; the connecting shaft 421 is inserted into the mounting hole 411, and the first insert hole 44 and the second insert hole 45 are respectively formed on the connecting arm 43 and the pressure frame 2; both the first insert hole 44 and the second insert hole 45 are adapted to the insert shaft 423.

[0045] When the pressure frame 2 is not engaged with the bracket 1, the horizontal plate 41 is located on the side of the transverse movable hole 4 near the connecting arm 43. At this time, the insertion shaft 423 is located inside the first insertion hole 44. When the pressure frame 2 moves down along the bracket 1, the horizontal plate 41 will not interfere with the movement of the bracket 1, allowing the platform to run smoothly. When the pressure frame 2 is engaged with the bracket 1, the connecting plate 42 is pulled upward to move the insertion shaft 423 out of the first insertion hole 44. Then, the connecting plate 42 is rotated 180 degrees about the connecting shaft 421 as the axis. Subsequently, the horizontal plate 41 is moved to the other end of the transverse movable hole 4 so that the insertion shaft 423 can be inserted into the second insertion hole 45. At this time, the horizontal plate 41 is located below the hydraulic cylinder 12. With the activation of the hydraulic cylinder 12, the pressure frame 2 can press the corrugated steel web main plate, so that the corrugated steel web main plate maintains a stable posture during assembly.

[0046] Additionally, refer to Figure 2 , Figure 4 and Figure 8 The bottom of the pressure frame 2 is provided with multiple sets of positioning components arranged in a straight line. Each set of positioning components includes a first guide plate 22 and a second guide plate 23. The first guide plate 22 and the second guide plate 23 are arranged in a figure-eight shape.

[0047] Due to their significant weight, the corrugated steel web plate is typically placed on bracket 1 using a hoisting method. However, the placed plate often exhibits a large positional deviation, requiring manual adjustment using hydraulic equipment before proceeding to the next assembly stage. In this embodiment, the flange plate to be assembled is first mounted on the clamping assembly. Then, a drive mechanism moves the flange plates on both sides of bracket 1 simultaneously towards each other. During this process, the skewed plate is compressed by the flange plates, thus restoring its correct position, meaning the edge of the plate remains parallel to the axis of bracket 1. Next, the drive mechanism moves the flange plates on both sides synchronously away from each other, separating them from the plate to reduce resistance during subsequent movement. Subsequently, the pressure frame 2 moves above bracket 1 and then downwards under the action of a workshop crane. At this point, if the main body plate is still misaligned, it will first contact the first guide plate 22 or the second guide plate 23. Under the action of the corresponding guide plate (first guide plate 22 or second guide plate 23), the main body plate will gradually move on the bracket 1 until both ends of the main body plate are in contact with the first guide plate 22 and the second guide plate 23. At this point, the position adjustment of the main body plate can be completed. Finally, the drive mechanism drives the two side flange plates to move towards each other again, aligning them with the main body plate, and the next spot welding operation can be carried out. After the corrugated web plate main body plate is placed, the assembly platform does not require manual correction of the position. The position adjustment of the main body plate can be completed during the pressing process of the pressure frame 2. This not only saves labor and time, but also significantly improves assembly efficiency while ensuring production quality.

[0048] Reference Figure 3 and Figure 5 The upper surface of the second movable arm 32 is provided with a groove 328 that is adapted to the touch plate 326.

[0049] The groove 328 provides a space for the contact plate 326; when the flange plate is not placed, the contact plate 326 is located above the second movable arm 32. During the placement of the flange plate, when the bottom of the flange plate contacts the contact plate 326, under the pressure of the flange plate, the contact plate 326 moves down and can completely enter the groove 328. At this time, the bottom surface of the flange plate contacts the upper surface of the second movable arm 32, increasing the effective contact area between the two, thereby improving the stability of the flange plate placement.

[0050] Reference Figure 3 and Figure 5 Rollers 325 are rotatably connected to the top of both sides of the lifting frame 324.

[0051] The groove 328 provides a space for the contact plate 326. When the flange plate is not in place, the contact plate 326 is positioned above the second movable arm 32. When the flange plate is placed, once the bottom of the flange plate contacts the contact plate 326, the contact plate 326 moves downwards and fully embeds itself into the groove 328 under the pressure of the flange plate. At this point, the bottom surface of the flange plate contacts the upper surface of the second movable arm 32. This process increases the effective contact area between the two, thereby further improving the stability of the flange plate placement.

[0052] Reference Figure 7 and Figure 8 The bottom end of the connecting shaft 421 is fixedly connected to the bottom shaft 422. The bottom shaft 422 has a circular cross-section, while the connecting shaft 421 has a polygonal cross-section.

[0053] The cross-section of the connecting shaft 421 is polygonal. When the connecting shaft 421 is engaged with the mounting hole 411, the connecting shaft 421 cannot rotate relative to the horizontal plate 41. This design effectively improves the stability of the horizontal plate 41. When the connecting plate 42 is moved upward, the connecting plate 42 will drive the connecting shaft 421 and the insert shaft 423 to move upward together. After the bottom shaft 422 of the connecting shaft 421 enters the mounting hole 411, the connecting plate 42, the connecting shaft 421, and the insert shaft 423 can rotate. At this time, the position of the horizontal plate 41 can be adjusted according to the usage requirements.

[0054] Among them, reference Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 8 The bracket 1 and the pressure frame 2 are respectively provided with guide ribs 13 and positioning ribs 24 at both ends, and the guide ribs 13 and positioning ribs 24 are compatible with each other.

[0055] Each end of the bracket 1 has two guide ribs 13, and each end of the pressure frame 2 has two positioning ribs 24. The spacing between the guide ribs 13 is greater than the spacing between the positioning ribs 24. When the pressure frame 2 moves downward, the positioning ribs 24 at its ends cooperate with the guide ribs 13 to guide the pressure frame 2, preventing it from tilting and thus improving the overall stability of the assembly platform. In this embodiment, the bottom of the positioning ribs 24 is inclined towards the axis of the pressure frame 2, which makes it easier to achieve the cooperation between the positioning ribs 24 and the guide ribs 13 in the initial stage when the pressure frame 2 and the bracket 1 begin to cooperate.

[0056] The implementation principle of the assembly platform for corrugated steel web plates in this application embodiment is as follows:

[0057] First, multiple corrugated steel web plates are placed sequentially on bracket 1 using a hoisting method. Then, the workshop crane uses a lifting platform 21 to lift the pressure frame 2 to a preparatory position above bracket 1. The flange plates to be assembled are placed on the clamping mechanism manually or with auxiliary equipment: a flange plate with several bolts is placed vertically between two first clamping plates 311 on the first movable arm 31; another type of flange plate is placed between two second clamping plates 322 on the second movable arm 32. The flange plate placed on the second clamping plate 322 presses down on the contact plate 326 due to its own weight, and the contact plate 326 pushes the lifting frame 324 downward through the connecting rod 329. The rollers 325 on both sides of the lifting frame 324 roll downward along the inclined surface of the limiting block 323, converting the vertical movement into a horizontal inward component force, overcoming the resistance of the spring 327, and pushing the two insertion rods 321 to move synchronously in opposite directions, thereby causing the two second clamping plates 322 to clamp the middle of the flange plate from both sides, achieving stable clamping of the flange plate.

[0058] Subsequently, motor 35 starts, and the output shaft of motor 35 meshes with first gear 34 through second gear 36, causing first gear 34 to drive rotating shaft 3 and lead screws 33 at both ends to rotate. First movable arm 31 and second movable arm 32, threadedly connected to lead screws 33, move synchronously towards each other along bracket 1 under the auxiliary guidance of support rod 37, pushing the flange plates on both sides towards the center. If the main body plate is misaligned, the flange plates will compress it during movement, automatically correcting it to a position parallel to the axis of bracket 1.

[0059] After the initial alignment of the corrugated steel web plate, motor 35 reverses and slightly retracts the clamping components on both sides, separating the flange plate from the main plate to reduce interference resistance during subsequent movement of the main plate. Then, the trolley drives the pressure frame 2 to move downwards. During this process, the positioning ribs 24 at both ends of the pressure frame 2 gradually engage with the guide ribs 13 fixed on the bracket 1, effectively preventing the pressure frame 2 from shifting during descent and ensuring the stability of the movement trajectory. If the main plate still has a slight positional deviation, its edge will contact the first guide plate 22 or the second guide plate 23 arranged in a V-shape at the bottom of the pressure frame 2, and will be automatically pushed to the preset position on the bracket 1 under the guidance of the inclined plane, achieving precise alignment.

[0060] After the pressure frame 2 is lowered into position, the operator lifts the connecting plate 42 upwards, causing the insertion shaft 423 to disengage from the first insertion hole 44 of the connecting arm 43. When the circular bottom shaft 422 at the bottom of the connecting shaft 421 rises into the mounting hole 411, the connecting plate 42 can be rotated 180 degrees. Subsequently, the horizontal plate 41 is pushed to the other end along the transverse movable hole 4, causing the insertion shaft 423 to be inserted into the second insertion hole 45 on the pressure frame 2. At this time, the horizontal plate 41 has moved below the hydraulic cylinder 12. The hydraulic cylinder 12 is activated, and its piston rod presses the horizontal plate 41 downwards, thereby transmitting pressure through the entire pressure frame 2 to the corrugated steel web plate, achieving reliable clamping.

[0061] After the main body plate is clamped and fixed, the drive mechanism drives the clamping components on both sides to move towards each other, so that the flange plate fits tightly against the sides of the aligned main body plate. The operator can then perform spot welding to complete the initial assembly of the corrugated steel web.

[0062] After welding, the hydraulic cylinder 12 returns, releasing the pressure on the pressure frame 2. The connecting plate 42 is lifted upwards, the insert shaft 423 is removed from the second insertion hole 45, the restriction on the horizontal plate 41 is released, and the horizontal plate 41 is pushed to reset it. Then, the crane lifts the pressure frame 2, moving it away from the bracket 1. As the entire corrugated steel web assembly is lifted away from the bracket 1, the pressure of the flange plate on the second movable arm 32 on the second clamping plate 322 disappears, and the restoring force of the spring 327 pushes the insert rod 321 and the second clamping plate 322 to move synchronously in opposite directions, opening to the initial width to facilitate the removal of subsequent workpieces.

[0063] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
