Description

Technical Field

[0001] This invention relates to the field of bridge railing processing technology, specifically to a welding equipment and method based on bridge railing processing. Background Technology

[0002] Bridge railings are railings installed on bridges to prevent out-of-control vehicles from going off the bridge. They serve to prevent vehicles from breaking through, passing under, or overturning the bridge, and also to beautify the bridge structure. During the welding process, multiple posts are usually inserted between two crossbeams for welding.

[0003] For example, a continuous welding device for beam-column bridge guardrail columns, disclosed in CN116900563B, uses a positioning sleeve, clamp, protective cover and locking bolts to connect the protective cover to the outer wall of the welding gun. The positioning sleeve is used to lock the positioning sleeve and the protective cover together with the clamp and locking bolts to prevent them from falling off. This device can prevent sparks from flying during the welding process and is safe and reliable. However, in actual use, during the manufacturing process of bridge railings, the posts on conventional straight sections of bridges are usually vertically installed. These upright posts perfectly match the standard railing panels, evenly distributing the impact force to the main bridge structure, meeting the design requirements for standardized anti-collision levels, and resulting in lower processing and installation costs. At bridge ends and on curved ramps, however, pre-bent curved posts are used. During a collision, the posts can absorb impact energy through controlled bending deformation, extending the impact time, reducing peak impact force, and better protecting drivers, passengers, and the bridge structure. Furthermore, the different shapes of the posts during manufacturing make it difficult to position them when splicing and welding multiple posts to two crossbeams. This also hinders the subsequent welding of posts with a certain degree of curvature, and prevents the assembly and welding of posts of different shapes and sizes with corresponding crossbeams, resulting in lower welding efficiency and certain usage defects.

[0004] Therefore, we propose a welding equipment and method based on bridge railing processing to solve the problems mentioned above. Summary of the Invention

[0022] By adopting the above technical solution, the position of the crossbeam can be adjusted.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the welding equipment and method based on bridge railing processing can simultaneously position curved posts and vertical posts, which facilitates the subsequent alignment of posts and beams. When welding curved posts, multiple posts can be reliably positioned to ensure the welding quality of railings of different shapes. At the same time, it is convenient to weld posts and beams of different sizes, thus expanding the applicability. After splicing and welding multiple posts and beams, it is convenient to remove the welded railing as a whole, avoiding obstruction during the subsequent removal of the railing as a whole and preventing scratches caused by collisions during the removal of the railing body. 1. When welding several columns and two crossbeams, first place the columns above the two rollers in each group. After the columns are placed, the electric cylinder can be activated to move the moving plate downwards. During the downward movement of the moving plate, the movable seat can also be moved downwards. During the downward movement of the movable seat, the sliding plate moves downwards. The elastic potential energy of the extension spring is less than that of the return spring. At this time, the downward movement of the movable seat can pull one end of the steel wire rope to move. The steel wire rope pulls the mounting plate through the guide wheel, causing the moving frame to slide on the movable plate. At this time, the support plate drives the pressure roller to move to the outside of the column. The support plate moves. This mechanism moves the movable rod and stretches the telescopic spring. The movable seat then moves downwards, causing the bottom of the push plate to contact the fixed seat. As the movable seat continues to move downwards, the sliding plate moves downwards, causing the push plate to contact the fixed seat. The continued downward movement of the movable seat then moves the fixed seat downwards, causing the movable rod to move downwards and pull the return spring. This, in turn, moves the movable plate downwards, causing the pressure roller to move downwards. The pressure roller's downward movement positions the column, allowing for the clamping and positioning of columns of different shapes. A pressure sensor is installed at the connection between the movable end of the electric cylinder and the movable plate. The pressure sensor reading continuously increases; when the movable plate stops moving, the movement ceases. The movable plate moves to avoid excessive pressure on the posts. Several posts can be positioned, and two crossbeams are fixed separately. The posts can be moved using pressure rollers and rollers, preventing the ends of the posts from being inserted into the crossbeams. At this time, workers can use a welding torch to weld the connection between the posts and crossbeams, facilitating the welding process of the guardrail. After several posts and two crossbeams are welded together to form a complete guardrail, the movable plate is reset after welding. After the movable plate is reset, the pressure rollers are reset, ensuring that the pressure rollers do not obstruct the top of the posts. At this point, the welded guardrail can be lifted directly upwards. This allows for simultaneous positioning of curved and vertical posts, avoiding the inconvenience of removing the entire fence. It facilitates the alignment of posts and beams later. When welding curved posts, multiple posts can be reliably positioned to ensure welding quality for fences of different shapes. It also facilitates welding of posts and beams of different sizes, expanding its applicability. After splicing and welding multiple posts and beams, it makes it easy to remove the entire fence, preventing obstruction and scratches from collisions during removal. 2. When welding guardrails of different sizes, the spacing between multiple posts may vary. To adjust the spacing of several posts, the handwheel can be turned to rotate the rotating rod. The rotating rod rotates and moves the adjusting frame through the spiral groove. After the adjusting frame moves, it can rotate the rotating frame. After the rotating frame rotates, it can push the adjusting plate upward. After the adjusting plate moves upward, the connecting frame rotates and the movable seat slides on the adjusting plate. The leftmost movable frame is fixed to the support platform, so that the movable frame can slide outside the support frame. The movable seat slides on the adjusting plate, which can adjust the spacing of multiple movable frames simultaneously and ensure that the spacing of multiple movable frames is consistent. This makes it convenient for workers to adjust the spacing of multiple posts according to the size of the guardrail, which is convenient for subsequent welding of guardrails with different post spacings. 3. When fixing the crossbeam, the crossbeam can be placed inside the fixing frame. Adjust the position of the crossbeam according to the position of the post to facilitate the insertion of the post end into the crossbeam. After adjusting the position of the crossbeam, the screw can be rotated to move the upper fixing plate down. The crossbeam can be clamped and fixed by the two fixing plates. Rotating the screw can drive the fixing frame to move, and the distance between the crossbeam and the post can be adjusted. The electric push rod can drive the connecting plate to move up and down, and the height of the fixing frame can be adjusted. When welding guardrails of different specifications and sizes, it is convenient to adjust the position of the crossbeam and facilitate the splicing and welding of the post and the crossbeam.

[0026] 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.

[0027] Please see Figures 1-10 The present invention provides a technical solution: a welding equipment based on bridge railing processing, including a support platform 1, and a support frame 101 symmetrically installed on the inner side of the support platform 1; Also includes: Several movable frames 102 are equidistantly slidably connected to the outside of two support frames 101, with the leftmost movable frame 102 fixedly connected to the support platform 1. Positioning component 2 is disposed on top and below a plurality of movable frames 102, and positioning component 2 includes mounting frame 201; Mounting brackets 201 are symmetrically mounted on top of several movable brackets 102. Each movable bracket 102 has two sets of mounting brackets 201 symmetrically arranged on top, and rollers 202 are rotatably connected between the two mounting brackets 201 in each set. A positioning seat 203 is fixedly mounted on one side of each of the several movable brackets 102. A movable plate 204 is slidably connected through the inside of the positioning seat 203. A movable frame 206 is slidably connected through the upper part of the inside of the movable plate 204. A mounting plate 205 is fixedly mounted on one side of the movable frame 206. A support plate 207 is fixedly installed at the other end of the movable frame 206. Limiting frames 208 are symmetrically installed at the bottom of the support plate 207, and pressure rollers 209 are rotatably connected between the two limiting frames 208. A connecting seat 210 is fixedly installed at the top of the support plate 207. Steel wire ropes 213 are symmetrically installed on the side of the mounting plate 205 near the movable plate 204. A through hole is symmetrically opened on one side of the movable plate 204 below the movable frame 206, and one end of the steel wire rope 213 passes through the through hole. At the same time, mounting blocks 214 are symmetrically installed on one side of the movable plate 204 below the two through holes. A guide wheel 215 is rotatably connected between the two mounting blocks 214 on each side, and the steel wire rope 213 is rotatably connected to the guide wheel 215. A fixed base 216 is fixedly installed at the bottom of the movable plate 204, and a moving rod 217 is symmetrically installed on the top of the fixed base 216. Both moving rods 217 are slidably connected to the positioning base 203. At the same time, a return spring 218 is sleeved on the outside of the two moving rods 217 below the positioning base 203. One end of the return spring 218 is fixedly connected to the positioning base 203, and a connecting block 219 is fixedly installed on the other end of the return spring 218. The connecting block 219 is fixedly connected to the moving rod 217. A sliding plate 220 is slidably connected through one side of the fixed base 216, and a push plate 221 is fixedly installed on the top of the sliding plate 220. The bottom of the push plate 221 abuts against the top of the fixed base 216. Meanwhile, a movable base 222 is fixedly installed on the bottom of the sliding plate 220, and a movable plate 224 is slidably connected through the interior of several movable bases 222. A U-shaped frame 223 is fixedly installed on the bottom of the support platform 1, and the movable plate 224 is slidably connected to the U-shaped frame 223. Meanwhile, electric cylinders 225 are symmetrically installed on both sides of the support platform 1, and the movable end of the electric cylinder 225 is fixedly connected to the movable plate 224.

[0028] Example 1: As Figures 1-6As shown, when welding several columns and two crossbeams, the columns are first placed above the two rollers 202 in each group. After the columns are placed, the electric cylinder 225 can be activated to move the moving plate 224 downward. During the downward movement of the moving plate 224, the movable seat 302 can be moved downward. During the downward movement of the movable seat 302, the sliding plate 220 moves downward. The elastic potential energy of the extension spring 212 is less than the elastic potential energy of the return spring 218. At this time, the downward movement of the movable seat 302 can pull one end of the steel wire rope 213 to move. The steel wire rope 213 pulls the mounting plate 205 to move through the guide wheel 215, so that the moving frame 206 slides on the movable plate 204. At this time, the support plate 207 is brought to the surface. When the pressure roller 209 moves to the outside and above the column, the support plate 207 moves, which drives the movable rod 211 to move and stretch the telescopic spring 212. At this time, the movable seat 302 moves down, causing the bottom of the push plate 221 to abut against the fixed seat 216, causing the movable seat 302 to continue to move down. After the sliding plate 220 moves down, the push plate 221 abuts against the fixed seat 216. The movable seat 302 continues to move down, which drives the fixed seat 216 to move down, causing the movable rod 217 to move down and pull the return spring 218. At this time, the movable plate 204 moves down, causing the pressure roller 209 to move down. The downward movement of the pressure roller 209 can position the column, and can press and position columns of different shapes. A pressure sensor is installed at the connection between the movable end of cylinder 225 and the moving plate 224. The pressure sensor reading continuously increases; when the moving plate 224 stops moving, it stops to prevent excessive pressure on the columns. Several columns can be positioned, and two crossbeams are fixed respectively. The columns can be moved using pressure rollers 209 and 202, preventing the column ends from being inserted into the crossbeams. At this time, workers can use a welding torch to weld the connection between the columns and crossbeams, facilitating the welding process of the guardrail. After several columns and two crossbeams are welded together, the guardrail is formed as a whole. After welding, the moving plate 224 resets, which in turn resets the pressure roller 209. After welding, the railing will not obstruct the view above several posts. At this point, the welded railing can be lifted and removed as a whole, avoiding the inconvenience of removing the railing as a whole. This allows for the simultaneous positioning of curved and vertical posts, facilitating the alignment of posts and beams later. When welding curved posts, multiple posts can be reliably positioned to ensure the welding quality of railings of different shapes. It also facilitates the welding of posts and beams of different sizes, expanding the applicability. After splicing and welding multiple posts and beams, it is easy to remove the welded railing as a whole, avoiding obstruction during the subsequent removal of the railing and preventing scratches from collisions during the removal process.

[0029] Adjustment component 3 is located below support platform 1; The adjustment assembly 3 also includes two sets of positioning plates 301 symmetrically installed on both sides of the bottom of the support platform 1. Each set of two positioning plates 301 is slidably connected to an adjustment plate 304. Several movable seats 302 are equidistantly slidably connected to the outside of the adjustment plate 304. At the same time, the top of the several movable seats 302 is symmetrically hinged to a connecting frame 303 between every two movable frames 102. The end of the connecting frame 303 away from the adjustment plate 304 is hinged to the adjacent movable frame 102. A rotating rod 305 is rotatably connected between the two positioning plates 301 on one side. One end of the rotating rod 305 passes through the positioning plate 301 on one side and is fixedly installed with a handwheel. Two spiral grooves 306 are opened on the outside of the rotating rod 305. Two adjusting brackets 307 are threadedly connected to the outside of the rotating rod 305 through the two spiral grooves 306. A limiting rod 308 is fixedly installed between the two positioning plates 301 on the other side. Both adjusting brackets 307 are slidably connected to the limiting rod 308. Rotating brackets 309 are symmetrically hinged to the top of the two adjusting brackets 307. The end of the rotating bracket 309 away from the adjusting bracket 307 is hinged to the adjusting plate 304.

[0030] Example 2: Figure 1 and Figures 7-8 As shown, when welding guardrails of different sizes, the spacing between multiple posts may be different. When adjusting the spacing of several posts, the handwheel can be turned to rotate the rotating rod 305. The rotation of the rotating rod 305 can drive the adjusting frame 307 to move through the spiral groove 306. After the adjusting frame 307 moves, it can drive the rotating frame 309 to rotate. After the rotating frame 309 rotates, it can push the adjusting plate 304 upward to move it upward. After the adjusting plate 304 moves upward, the connecting frame 303 rotates. The movable seat 302 slides on the adjusting plate 304. The leftmost movable frame 102 is fixed to the support platform 1, so that the movable frame 102 can slide outside the support frame 101 when the adjusting plate 304 moves upward. The movable seat 302 slides on the adjusting plate 304, which can adjust the spacing of multiple movable frames 102 simultaneously and ensure that the spacing of multiple movable frames 102 is consistent. This makes it convenient for workers to adjust the spacing of multiple posts according to the size of the guardrail, which is convenient for subsequent welding of guardrails with different post spacing.

[0031] Fixing components 4 are symmetrically arranged on the top of the support platform 1; The fixing component 4 includes a fixing frame 401 symmetrically arranged on the top of the support platform 1, and a fixing plate 402 symmetrically arranged inside the fixing frame 401. The lower fixing plate 402 is fixedly connected to the fixing frame 401, and a screw 403 is rotatably connected to the top center of the upper fixing plate 402. The screw 403 is threadedly connected to the fixing frame 401. Guide rods 404 are symmetrically installed on both sides of the top of the upper fixing plate 402, and the guide rods 404 are slidably connected to the fixing frame 401. A crossbeam 406 is provided on one side of the fixed frame 401, and a screw rod 405 is threaded through the center of the crossbeam 406. One end of the screw rod 405 is rotatably connected to the fixed frame 401. Meanwhile, positioning rods 407 are symmetrically slidably connected through both sides of the crossbeam 406. One end of the positioning rod 407 is fixedly connected to the fixed frame 401. Vertical frames 408 are symmetrically installed at the bottom of the crossbeam 406, and connecting plates 410 are fixedly installed at the bottom of the two vertical frames 408. Meanwhile, an electric push rod 409 is fixedly installed at the bottom of the support platform 1 between the two vertical frames 408, and the movable end of the electric push rod 409 is fixedly connected to the connecting plate 410.

[0032] Example 3: Figure 1 and Figures 9-10 As shown, when fixing the crossbeam, the crossbeam can be placed inside the fixing frame 401. The position of the crossbeam can be adjusted according to the position of the column to facilitate the insertion of the column end into the crossbeam. After the position of the crossbeam is adjusted, the screw 403 can be rotated to move the upper fixing plate 402 down. The crossbeam can be clamped and fixed by the two fixing plates 402. Rotating the screw 405 can drive the fixing frame 401 to move, which can adjust the distance between the crossbeam and the column. The electric push rod 409 can drive the connecting plate 410 to move up and down, which can adjust the height of the fixing frame 401. When welding guardrails of different specifications and sizes, it is convenient to adjust the position of the crossbeam and facilitate the splicing and welding of the column and the crossbeam.

[0033] Working principle: When using welding equipment based on bridge railing processing, firstly, according to... Figures 1-10As shown, when welding several columns and two crossbeams, the columns are first placed above the two rollers 202 in each group. After the columns are placed, the electric cylinder 225 can be activated to move the moving plate 224 downward. During the downward movement of the moving plate 224, the movable seat 302 can be moved downward. During the downward movement of the movable seat 302, the sliding plate 220 moves downward. The elastic potential energy of the extension spring 212 is less than the elastic potential energy of the return spring 218. At this time, the downward movement of the movable seat 302 can pull one end of the steel wire rope 213 to move. The steel wire rope 213 passes through the guide wheel. 215 pulls the mounting plate 205 to move, causing the movable frame 206 to slide on the movable plate 204. At this time, the support plate 207 drives the pressure roller 209 to move to the outside of the column. The movement of the support plate 207 can drive the movable rod 211 to move and stretch the telescopic spring 212. At this time, the movable seat 302 moves down, causing the bottom of the push plate 221 to abut against the fixed seat 216. The movable seat 302 continues to move down, and the sliding plate 220 moves down, causing the push plate 221 to abut against the fixed seat 216. After the movable seat 302 continues to move down, it can drive the fixed seat 216 to move down. The moving rod 217 moves downward, pulling the return spring 218. This causes the movable plate 204 to move downward, which in turn moves the pressure roller 209 downward. The downward movement of the pressure roller 209 positions the column, allowing for the clamping and positioning of columns of different shapes. A pressure sensor is installed at the connection between the movable end of the electric cylinder 225 and the moving plate 224. As the pressure sensor reading increases, the moving plate 224 stops moving when it stops, preventing excessive pressure on the column. This allows for the positioning of several columns and the fixing of two crossbeams, via the pressure roller. 209 and roller 202 can move the uprights to prevent the ends of the uprights from being inserted into the crossbeams. At this time, the workers can use a welding gun to weld the connection between the uprights and the crossbeams, which facilitates the welding process of the guardrail. After several uprights and two crossbeams are welded together, the guardrail is formed as a whole. After the welding is completed, the moving plate 224 is reset. After the moving plate 224 is reset, the pressure roller 209 is reset. After the pressure roller 209 is reset, it will not obstruct the top of several uprights. At this time, the welded guardrail can be lifted up and removed directly to avoid the inconvenience of removing the guardrail as a whole. When welding guardrails of different sizes, the spacing between multiple posts may vary. To adjust the spacing of several posts, a handwheel can be turned to rotate the rotating rod 305. The rotation of the rotating rod 305, via the spiral groove 306, moves the adjusting frame 307. The moving adjusting frame 307 then rotates the rotating frame 309. This rotation pushes the adjusting plate 304 upwards, causing the connecting frame 303 to rotate. The movable seat 302 slides on the adjusting plate 304. The leftmost movable frame 102 is fixed to the support platform 1, allowing the movable frame 102 to slide outside the support frame 101 as the adjusting plate 304 moves upwards. 302 slides on the adjusting plate 304, which can simultaneously adjust the spacing of multiple movable frames 102 and ensure that the spacing of multiple movable frames 102 is consistent. When fixing the crossbeam, the crossbeam can be placed inside the fixed frame 401. The position of the crossbeam is adjusted according to the position of the column, so that the end of the column can be inserted into the crossbeam later. After the position of the crossbeam is adjusted, the screw 403 can be rotated to move the upper fixed plate 402 down. The crossbeam can be clamped and fixed by the two fixed plates 402. Rotating the screw 405 can drive the fixed frame 401 to move, which can adjust the spacing between the crossbeam and the column. The electric push rod 409 can drive the connecting plate 410 to move up and down, which can adjust the height of the fixed frame 401.

10. A method of using welding equipment for bridge railing processing, comprising the welding equipment for bridge railing processing as described in claim 9, characterized in that, The specific usage steps are as follows: Step 1: When welding several columns and two crossbeams, the columns are first placed above the two rollers (202) of each group. After the columns are placed, the electric cylinder (225) is activated to drive the moving plate (224) to move down. During the downward movement of the moving plate (224), the movable seat (302) is driven down. During the downward movement of the movable seat (302), the sliding plate (220) moves down. The elastic potential energy of the extension spring (212) is less than that of the return spring (218). At this time, the downward movement of the movable seat (302) pulls one end of the wire rope (213) to move. The wire rope (213) passes through the guide wheel (218) to move. 15) Pull the mounting plate (205) to move, causing the movable frame (206) to slide on the movable plate (204). At this time, the support plate (207) drives the pressure roller (209) to move to the outside of the column. The movement of the support plate (207) drives the movable rod (211) to move and stretch the telescopic spring (212). At this time, the movable seat (302) moves down, causing the bottom of the push plate (221) to abut against the fixed seat (216). The movable seat (302) continues to move down. The sliding plate (220) moves down, causing the push plate (221) to abut against the fixed seat (216). After that, the movable seat (302) continues to move down. The fixed base (216) is moved down, causing the moving rod (217) to move down and pull the return spring (218). At this time, the movable plate (204) is moved down, causing the pressure roller (209) to move down. The pressure roller (209) is positioned to press and position the columns of different shapes. A pressure sensor is installed at the connection between the movable end of the electric cylinder (225) and the movable plate (224). The pressure sensor value increases continuously. When the movable plate (224) does not move, the movable plate (224) stops moving to avoid excessive pressure on the columns. Several columns are positioned, and two are respectively placed. The crossbeam is fixed, and the column is moved by the pressure roller (209) and the roller (202) to avoid inserting the end of the column into the crossbeam. At this time, the staff holds the welding gun to weld the connection between the column and the crossbeam, which facilitates the welding process of the guardrail. After several columns and two crossbeams are welded together, the guardrail is formed as a whole. After the welding is completed, the moving plate (224) is reset. After the moving plate (224) is reset, the pressure roller (209) is reset. After the pressure roller (209) is reset, it will not block the top of several columns. At this time, the welded guardrail is lifted up and removed directly to avoid the inconvenience of removing the guardrail as a whole. Step Two: When welding guardrails of different sizes, the spacing between multiple posts may be different. When adjusting the spacing of several posts, the handwheel is turned to drive the rotating rod (305) to rotate. The rotating rod (305) rotates and drives the adjusting frame (307) to move through the spiral groove (306). After the adjusting frame (307) moves, it drives the rotating frame (309) to rotate. After the rotating frame (309) rotates, it pushes the adjusting plate (304) upward to move it up. After the adjusting plate (304) moves up, the connecting frame (303) rotates. The movable seat (302) slides on the adjusting plate (304). The leftmost movable frame (102) is fixed to the support platform (1), so that the adjusting plate (304) moves up and the movable frame (102) slides outside the support frame (101). The movable seat (302) slides on the adjusting plate (304). Step 3: When fixing the crossbeam, place the crossbeam inside the fixing frame (401), adjust the position of the crossbeam according to the position of the column, so that the end of the column can be inserted into the crossbeam later. After adjusting the position of the crossbeam, rotate the screw (403) to move the upper fixing plate (402) down, and clamp and fix the crossbeam through the two fixing plates (402). Rotate the screw (405) to drive the fixing frame (401) to move, adjust the distance between the crossbeam and the column, and drive the connecting plate (410) to move up and down through the electric push rod (409) to adjust the height of the fixing frame (401).
