[0002] Segmental beam formwork is a specialized formwork system used for casting and shaping concrete bridge segments.

[0032] In this embodiment, when a modular adjustable formwork device for segmental beams needs adjustment during use, the motor 409 is activated. The motor 409 drives the first gear 412 to rotate, which in turn drives the meshing second gear 413 and third gear 414 to rotate. The rotation of the third gear 414 drives the third rotating shaft 415 to rotate, which in turn drives the first canine tooth 416 to rotate. Then, the second hydraulic rod 408 is activated to move the motor 409 and the first connecting plate 411 until the outer surface of the rotating first canine tooth 416 meshes with the outer surface of the fourth canine tooth 507, thereby driving the fourth canine tooth 507 to rotate. The rotation of the fourth canine tooth 507 drives the first canine tooth 416 to rotate. The drive wheel 506 rotates, which in turn drives the track 503 to rotate. The track 503, in turn, drives the two driven wheels 502 to rotate. The driven wheels 502, in turn, drive the driven shaft 501 to rotate. The driven shaft 501, in turn, drives the second rotating rod 206 to rotate.

The first helical gear 202, in turn, drives the first rotating rod 201 to rotate. The first rotating rod 201, in turn, drives the first connecting block 203 and the first rotating plate 211 to rotate. The first connecting block 203 will drive the first moving template 204 to rotate and move. When the first rotating plate 211 rotates, it will drive the first rotating shaft 212 to rotate and move.

The inner wall of one side of the second rotating plate 213 will rotate along the outer surface of the first rotating shaft 212. The inner wall of the other side of the second rotating plate 213 will rotate along the outer surface of the second rotating shaft 214 and drive the second rotating shaft 214 to move. When the second rotating shafts 214 on both sides of the side template 303 move, they will drive the side template 303 to move. The side template 303 will drive the side support body 301 to move along the outer surface of the slide rail 302 until the outer surface of one side of the first moving template 204 and the second moving template 209 is in contact with the outer surface of the fixed template 1. The surfaces of the first movable template 204 and the second movable template 209 engage with the outer surface of the side template 303, thereby adjusting the segmental beam template. This device rotates the first rotating rod 201 and the second rotating rod 206. When the first rotating rod 201 rotates, it moves the side template 303. Simultaneously, the first rotating rod 201 and the second rotating rod 206 move the first movable template 204 and the second movable template 209. One outer surface of the first movable template 204 and the second movable template 209 is in contact with the outer surface of the fixed template 1, and the other outer surface of the first movable template 204 and the second movable template 209 is in contact with the outer surface of the side template 303, thus enabling adjustment of the segmental beam template.This invention solves the problem that the reusability of fixed-size segmental beam formwork in existing technologies is limited to segmental beams of the same size, thus increasing equipment investment costs when other sizes are required in the project.
[0033] like Figure 1-8 As shown, one end of each of the four second rotating shafts 214 is rotatably connected to the inner walls of the two side templates 303. The moving assembly 4 includes a bottom mold carriage 401, a sliding plate 402 is slidably connected to the inner wall of the bottom mold carriage 401, and a fixing plate 403 is fixedly connected to the outer surface of one side of the sliding plate 402. A first hydraulic rod 404 is provided at the top of the bottom mold carriage 401 near the four corners. The tops of the four first hydraulic rods 404 are fixedly connected to the bottom template 405 by screws. The outer surface of the bottom template 405 is in contact with the inner wall of the fixing template 1. Support blocks 406 are fixedly connected to the outer surface of the slide plate 402 near both side edges. A lead screw 407 is rotatably connected between the inner walls of the two support blocks 406. The outer surface of the lead screw 407 is threadedly connected to the inner wall of the bottom mold carriage 401. A second hydraulic rod 408 is provided on one side of the outer surface of the fixed plate 403. A motor 409 is provided at one end of the second hydraulic rod 408. An output shaft 410 is fixedly connected to the output end of the motor 409. A first connecting plate 411 is fixedly connected to the outer surface of the motor 409. The outer surface of the output shaft 410 is movably connected to... A first gear 412 is fixedly sleeved on the outer surface of the output shaft 410, passing through the inner wall of the first connecting plate 411. A second gear 413 is movably embedded in the inner wall of the first connecting plate 411 near one edge. A third rotating shaft 415 is movably embedded in the inner wall of the first connecting plate 411 near the other edge. A third gear 414 is fixedly sleeved on the outer surface of the third rotating shaft 415 near one end. The outer surface of the second gear 413 meshes with the outer surface of the first gear 412, and the outer surface of the third gear 414 meshes with the outer surface of the first gear 412. The two gears are meshed. The other end of the third rotating shaft 415 is fixedly connected to the first dog tooth 416. The outer surface of the lead screw 407 is fixedly sleeved with the second dog tooth 417 near one end. The outer surface of one side of the second gear 413 is fixedly connected with the third dog tooth 418. A transmission assembly 5 is provided between the outer surfaces of the two second rotating rods 206. The transmission assembly 5 includes two driven shafts 501. One end of the two driven shafts 501 is fixedly connected to one end of the two second rotating rods 206 respectively. The outer surfaces of the two driven shafts 501 are fixedly sleeved with driven wheels 502.
[0034] In this embodiment, during the use of a modular adjustable formwork device for segmental beams, the operator first needs to move the bottom formwork trolley 401 to the bottom of the fixed formwork 1. At this time, the operator starts the motor 409, which drives the output shaft 410 to rotate. When the output shaft 410 rotates, it drives the first gear 412 to rotate. When the first gear 412 rotates, it simultaneously drives the meshing second gear 413 and third gear 414 to rotate. When the second gear 413 rotates, it drives the third canine tooth 418 to rotate. When the third gear 414 rotates, it drives the outer surface of the third rotating shaft 415 to rotate along the first connecting plate 4. The rotation of the inner wall of 11 simultaneously drives the first dog tooth 416 to rotate. At this time, the second hydraulic rod 408 is activated, driving the motor 409 to move. The motor 409 drives the first connecting plate 411 to move, which in turn drives the rotating third dog tooth 418 to mesh with the outer surface of the second dog tooth 417, causing the second dog tooth 417 to rotate. When the second dog tooth 417 rotates, it drives the lead screw 407 to rotate. The two ends of the lead screw 407 rotate along the inner wall of the support block 406. When the lead screw 407 rotates, it drives the inner wall of the bottom mold carriage 401 to move spirally along the outer surface of the lead screw 407 until the bottom mold carriage 401 moves to the fixed template 1. Directly below, the second hydraulic rod 408 is stopped. At this time, the first hydraulic rod 404 is activated, causing the outer surface of the bottom template 405 to fit against the inner wall of the fixed template 1. While adjusting the segmental beam template, the second hydraulic rod 408 is activated, causing the rotating first dog tooth 416 to mesh with the fourth dog tooth 507, thereby causing the fourth dog tooth 507 to rotate. The rotating fourth dog tooth 507 will drive the track 503 to rotate. When the track 503 rotates, it will drive the driven wheel 502 to rotate. The driven wheel 502 will drive the second rotating rod 206 to rotate. When the second rotating rod 206 rotates, it will drive the first moving template 204 and the second moving template 205 to rotate. The plate 209 rotates to adjust the segmental beam template. This device is equipped with a moving component 4. When the bottom formwork trolley 401 needs to be moved, the second hydraulic rod 408 drives the third dog tooth 418 to mesh with the second dog tooth 417, thereby driving the lead screw 407 to rotate. The rotation of the lead screw 407 drives the bottom formwork trolley 401 to move. When the adjustment template component 2 needs to be moved, the second hydraulic rod 408 drives the first dog tooth 416 to mesh with the fourth dog tooth 507. This switchable movement mode allows the device to adapt to different working requirements, thereby improving the applicability of the segmental beam modular adjustable template device.
[0035] like Figure 1-8As shown, a track 503 is movably fitted between the outer surfaces of the two driven wheels 502. A second connecting plate 504 is fixedly connected to the outer surface of the fixed template 1 near one edge. A drive shaft 505 is movably embedded in the inner wall of the second connecting plate 504. A drive wheel 506 is fixedly fitted on the outer surface of the drive shaft 505. The outer surface of the drive wheel 506 meshes with the inner wall of the track 503. A fourth dog tooth 507 is fixedly fitted on the outer surface of the drive shaft 505 near one end.
[0036] In this embodiment, during the use of a modular adjustable template device for segmental beams, the second hydraulic rod 408 is activated during the adjustment of the segmental beam template. This causes the outer surface of the rotating first dog tooth 416 to mesh with the outer surface of the fourth dog tooth 507, thereby causing the fourth dog tooth 507 to rotate. The rotation of the fourth dog tooth 507 causes the drive shaft 505 to rotate, which in turn causes the drive wheel 506 to rotate. The rotation of the drive wheel 506 causes the meshing track 503 to rotate, which in turn causes two driven wheels 502 to rotate. The simultaneous rotation of the two driven wheels 502 causes the corresponding driven shaft 501 to rotate, which in turn causes two second rotating rods 206 to rotate. When drive wheel 506 rotates, it simultaneously drives the second moving template 209 and the second helical gear 207 to rotate. When the second helical gear 207 rotates, it drives the meshing first helical gear 202 to rotate. When the first helical gear 202 rotates, it drives the first rotating rod 201 to rotate. When the first rotating rod 201 rotates, it drives the first moving template 204 to rotate. This device, by setting transmission component 5, drives the track 503 to rotate when drive wheel 506 rotates. When track 503 rotates, it simultaneously drives the two driven wheels 502 to rotate, thereby driving the two second rotating rods 206 and the first rotating rod 201 to rotate simultaneously. This ensures the synchronicity of the movement of the first moving template 204 and the second moving template 209, and improves the synchronization accuracy and stability of the segmental beam modular adjustable template device.
[0037] The usage and working principle of this device: During the use of this modular adjustable formwork device for segmental beams, the operator first moves the bottom formwork trolley 401 to the bottom of the fixed formwork 1. At this time, the operator starts the motor 409, which drives the output shaft 410 to rotate. The rotation of the output shaft 410 drives the first gear 412 to rotate. The rotation of the first gear 412 simultaneously drives the meshing second gear 413 and third gear 414 to rotate. The rotation of the second gear 413 drives the third canine tooth 418 to rotate. The rotation of the third gear 414 drives the outer surface of the third rotating shaft 415 to rotate along the inner wall of the first connecting plate 411, simultaneously driving the first canine tooth 416 to rotate. At this time, the second hydraulic rod 408 is activated. The motor 409 moves, which in turn moves the first connecting plate 411. This causes the rotating third dog tooth 418 to mesh with the outer surface of the second dog tooth 417, causing the second dog tooth 417 to rotate. The rotation of the second dog tooth 417 causes the lead screw 407 to rotate. The two ends of the lead screw 407 rotate along the inner wall of the support block 406. The rotation of the lead screw 407 causes the inner wall of the bottom mold trolley 401 to spiral along the outer surface of the lead screw 407 until the bottom mold trolley 401 is directly below the fixed template 1. The second hydraulic rod 408 stops, and the first hydraulic rod 404 is activated to bring the outer surface of the bottom template 405 into contact with the inner wall of the fixed template 1. The segmental beam template is then adjusted. At this point, the second hydraulic rod 408 is activated again. The first dog tooth 416, driven by the rotation of the first dog tooth 416, meshes with the fourth dog tooth 507, thereby causing the fourth dog tooth 507 to rotate. The rotation of the fourth dog tooth 507 causes the drive shaft 505 to rotate, which in turn causes the drive wheel 506 to rotate. The rotation of the drive wheel 506 causes the meshing track 503 to rotate, which in turn causes the two driven wheels 502 to rotate. The simultaneous rotation of the two driven wheels 502 causes the corresponding driven shaft 501 to rotate. The rotation of the driven shaft 501 simultaneously causes the two second rotating rods 206 to rotate. The rotation of the second rotating rods 206 simultaneously causes the second helical gears 207 and the second connecting block 208 at both ends to rotate. The rotation of the second connecting block 208 causes the second moving... When template 209 rotates, the rotation of the second helical gear 207 drives the meshing first helical gear 202 to rotate. The first helical gear 202 drives the first rotating rod 201 to rotate. When the first rotating rod 201 rotates, it simultaneously drives the first connecting block 203 and the first rotating plate 211 to rotate. The first connecting block 203 drives the first movable template 204 to rotate and move. When the first rotating plate 211 rotates, it drives the first rotating shaft 212 to rotate and move. When the first rotating shaft 212 moves, it drives the second rotating plate 213 to move. One inner wall of the second rotating plate 213 rotates along the outer surface of the first rotating shaft 212, and the other inner wall of the second rotating plate 213 rotates along the outer surface of the second rotating shaft 214, simultaneously driving the second rotating shaft 214 to move.When the second rotating shafts 214 on both sides of the side formwork 303 move, they drive the side formwork 303 to move. The side formwork 303 then drives the side support body 301 to move along the outer surface of the slide rail 302 until one outer surface of the first moving formwork 204 and the second moving formwork 209 engages with the outer surface of the fixed formwork 1, and the other outer surface of the first moving formwork 204 and the second moving formwork 209 engages with the outer surface of the side formwork 303, thereby adjusting the segmental beam formwork.
