Description

Technical Field

[0001] The present application relates to the technical field of tunnel construction, and in particular to an arch connection plate positioning mold. Background Art

[0002] During the tunnel construction process, it is usually necessary to process steel arch frames on the construction site. Multiple sections of I-beams need to be connected in sequence according to the tunnel contour size to form a steel arch frame. The ends of two adjacent sections of I-beams are connected and fixed by connecting plates to form a steel arch frame. The connecting plates need to be pre-welded to the ends of the I-beams, and threaded holes are reserved on the connecting plates to facilitate the fixing and installation of the connecting plates on the two adjacent I-beams.

[0003] When welding the connecting plate at the end of the I-beam, manual welding is usually performed. In order to ensure that the threaded holes reserved on the two adjacent connecting plates can be aligned, a positioning mold is required to position the connecting plate when welding the connecting plate at the end of the I-beam.

[0004] At present, relevant steel arch frame link plate positioning molds, such as the Chinese patent with authorization announcement number CN210033473U, disclose a tunnel steel arch frame connection plate positioning mold, including a positioning frame for cooperating with the inner groove of the I-beam, the outer side of the positioning frame cooperates with the connection plate to be welded, and the positioning frame is provided with a positioning piece that cooperates with the reserved bolt holes on the connection plate.

[0005] The positioning mold in the related art can only be suitable for I-beams of fixed sizes. If the size of the I-beam changes, the positioning mold can only be re-customized according to the size of the I-beam, which has low applicability. Utility Model Content

[0006] In order to enable the positioning mold to meet the needs of I-beams of different sizes and improve applicability, the present application provides an arch connecting plate positioning mold.

[0007] The present application provides an arch frame connection plate positioning mold adopts the following technical solution:

[0008] A positioning mold for an arch frame connecting plate comprises a positioning frame clamped in an I-beam, the I-beam comprises a web and two wing plates relatively fixed on the web, the positioning frame comprises a first positioning plate for installation with the connecting plate and a second positioning plate fixedly connected to the first positioning plate, a positioning piece for positioning the connecting plate is installed on the first positioning plate, the first positioning plate and the second positioning plate have the same shape and size and are both smaller than the distance between the two wing plates, and also comprises a locking mechanism for clamping the second positioning plate on the wing plate and an adjustment mechanism for adapting the second positioning plate to different wing plate spacings.

[0009] By adopting the above technical solution, when the connecting plate needs to be installed at the end of the I-beam, the positioning piece of the first positioning plate is aligned with the threaded hole reserved on the connecting plate to achieve positioning. The second positioning plate is clamped with the wing plate through a locking mechanism, and the distance of the adjustment mechanism is adjustable, so that the second positioning plate can be installed between wing plates with different spacings, so that the positioning frame can meet the use requirements of I-beams of different sizes, thereby improving applicability.

[0010] Optionally, the locking mechanism includes a mounting plate on which a first clamping plate and a second clamping plate are slidably mounted, and the locking mechanism also includes a clamping spring that brings the first clamping plate and the second clamping plate closer to each other, the clamping spring is fixed on the mounting plate, and the wing plate is clamped between the first clamping plate and the second clamping plate.

[0011] By adopting the above technical solution, the clamping spring brings the first clamping plate and the second clamping plate closer to each other, clamps the wing plate, and thus enables the second positioning plate to be clamped on the wing plate.

[0012] Optionally, a sliding groove is opened in the length direction of the mounting plate, a first slider is fixed on the first clamping plate, the width of the first slider close to the first clamping plate is smaller than the width of the side away from the first clamping plate, a second slider is fixed on the second clamping plate, the width of the second slider close to the second clamping plate is smaller than the width of the side away from the second clamping plate, the cross-sections of the first slider and the second slider are the same as the cross-section of the sliding groove, and the first slider and the second slider are both slidably connected to the sliding groove.

[0013] By adopting the above technical solution, the first slider and the second slider are slidably installed in the slide groove, which reduces the first clamping plate and the second clamping plate from separating from the mounting plate in the vertical direction and improves the stability of the first clamping plate and the second clamping plate when clamping.

[0014] Optionally, the first clamping plate and the second clamping plate both have a slope on the side away from the mounting plate that gradually slopes downward from the side close to the wing plate to the side away from the wing plate.

[0015] By adopting the above technical solution, when the wing plate is clamped, the wing plate moves along the inclined surfaces on the first clamping plate and the second clamping plate toward the side close to the mounting plate, so that the second positioning plate can be quickly clamped on the wing plate.

[0016] Optionally, the adjustment mechanism includes a fixed block fixed on the mounting plate, a gear is rotatably mounted on the fixed block, a rack is meshed on the side of the gear close to the mounting plate, the length direction of the rack is perpendicular to the length direction of the wing plate, and the end of the rack away from the gear is mounted on a second positioning plate. An insertion rod and an adjustment component for making the insertion rod close to or away from the gear are also slidably mounted on the fixed block.

[0017] By adopting the above technical solution, when the distance between the wing plate and the second positioning plate increases or decreases, it can be adjusted by the extension distance of the rack. After the adjustment is completed, the adjustment component makes the insertion rod press against the gear to fix the position of the second positioning plate.

[0018] Optionally, the adjustment assembly includes a fixing plate fixed on the fixing block, the insertion rod is slidably mounted on the fixing plate, the axis of the insertion rod is perpendicular to the axis of the gear, a fixing ring is fixed to the end of the insertion rod away from the gear, a clamping spring is sleeved on the outside of the insertion rod, one end of the clamping spring is fixed to the fixing ring, and the other end is fixedly connected to the fixing plate.

[0019] By adopting the above technical solution, the spring is tightened to tighten the fixing ring and the fixing plate, so that the insertion rod is pressed against the gear to fix the position of the rack. When the extension length of the rack needs to be adjusted, the gear can be rotated by pulling the fixing ring away from the fixing plate, so that the extension length of the rack can meet the requirements of the wing plates with different spacings, thereby ensuring the accurate positioning of the second positioning plate.

[0020] Optionally, a limiting block is fixed to one end of the rack away from the second positioning plate to reduce the possibility that the rack completely disengages from the gear.

[0021] By adopting the above technical solution, the limiting block fixes the rack away from one side of the second positioning plate, thereby reducing the situation where the rack completely escapes from the gear.

[0022] Optionally, a sliding rod is fixed to one side of the second positioning plate close to the adjustment mechanism, the length direction of the sliding rod is parallel to the wing plate, and a connecting block is fixed to one end of the rack close to the second positioning plate, the connecting block is provided with a slot, and the slot is slidably connected to the sliding rod.

[0023] By adopting the above technical solution, when the size of the I-beam changes, the distance between the wing plate and the web will also change accordingly. The slot and the sliding rod are slidably connected to ensure that the second positioning plate abuts against the web, and the locking mechanism can stably clamp the second connecting plate on the wing plate.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. When the connecting plate needs to be installed at the end of the I-beam, the positioning piece of the first positioning plate is aligned with the threaded hole reserved on the connecting plate to achieve positioning. The second positioning plate is clamped with the wing plate through a locking mechanism, and the distance of the adjustment mechanism is adjustable, so that the second positioning plate can be installed between wing plates with different spacings, so that the positioning frame can meet the use requirements of I-beams of different sizes, improving applicability;

[0026] 2. When the distance between the wing plate and the second positioning plate increases or decreases, it can be adjusted by the extension distance of the rack. After the adjustment is completed, the adjustment component makes the insertion rod press against the gear to fix the position of the second positioning plate;

[0027] 3. As the size of the I-beam changes, the distance between the wing plate and the web will also change. The slotted and slidingly connected slide bar can ensure that the second positioning plate abuts against the web while the locking mechanism can stably clamp the second connecting plate on the wing plate.

[0036] The I-beam 1 includes two wing plates 11 and a web plate 12 . The two wing plates 11 are parallel and relatively fixed on both sides of the web plate 12 . The web plate 12 is vertically fixedly connected to the middle section of the wing plates 11 .

[0037] The positioning frame 2 includes a first positioning plate 21 and a second positioning plate 22 which are parallel to each other and of the same size. The first positioning plate 21 is located on one side close to the end of the I-beam 1. Three parallel connecting rods 23 are fixed between the second positioning plate 22 and the first positioning plate 21. One end of the connecting rod 23 is fixed to the first positioning plate 21, and the other end is fixed to the second positioning plate 22. The length of the first positioning plate 21 and the second positioning plate 22 is less than the distance between the two wing plates 11, and the first positioning plate 21 and the second positioning plate 22 are both in contact with the web 12.

[0038] Reference Figure 1 and Figure 2 The first positioning plate 21 is threadedly connected with two bolts 211. A connecting plate 5 is provided on one side of the first positioning plate 21 close to the end of the I-beam 1. Two threaded holes 51 are reserved on the connecting plate 5. After the threaded holes 51 are aligned one by one with the bolts 211 on the first positioning plate 21, the connecting plate 5 abuts against the end of the I-beam 1. At this time, the connecting plate 5 is welded to ensure the accuracy of welding.

[0039] Reference Figure 3 The locking mechanism 3 includes a mounting plate 31, a slot 311 is provided on the mounting plate 31, and the slot 311 is provided along the length direction of the mounting plate 31, and a first slider 32 and a second slider 33 are slidably installed in the slot 311, and the first slider 32 and the second slider 33 can slide horizontally along the length direction of the slot 311, and the width of the first slider 32 and the second slider 33 away from the slot opening of the slot 311 is greater than the width of the side close to the slot opening of the slot 311, so that the first slider 32 and the second slider 33 are both T-shaped blocks, and the cross-section of the slot 311 is the same as the cross-section of the first slider 32 and the second slider 33, thereby reducing the situation where the first slider 32 and the second slider 33 are separated from the slot 311 in the vertical direction.

[0040] A clamping spring 34 is fixed to the side of the first slider 32 and the second slider 33 that are away from each other. One end of the clamping spring 34 is fixedly connected to the inner wall of the slide groove 311, and the other end is fixed to the first slider 32 or the second slider 33. The clamping spring 34 gives the first slider 32 and the second slider 33 a force to move closer to each other.

[0041] A first clamping plate 35 is fixed to one end of the first slider 32 away from the slide slot 311, and a second clamping plate 36 is fixed to one end of the second slider 33 away from the slide slot 311. The first clamping plate 35 and the second clamping plate 36 are parallel to each other. Under the action of the clamping spring 34, the first clamping plate 35 and the second clamping plate 36 are close to each other.

[0042] The first clamping plate 35 and the second clamping plate 36 have an inclined surface on the side away from the mounting plate 31, which gradually slopes downward from the side close to the wing plate 11 to the side away from the wing plate 11, so that the edge of the wing plate 11 can be clamped between the first clamping plate 35 and the second clamping plate 36 along the inclined surface and clamped and fixed by the first clamping plate 35 and the second clamping plate 36.

[0043] Reference Figure 4 The adjustment mechanism 4 includes a fixed block 41, which is fixed to a side of the mounting plate 31 away from the slide slot 311. A gear 42 is rotatably mounted on the fixed block 41, and a rotation axis of the gear 42 is parallel to the length direction of the wing plate 11.

[0044] A rack 43 is meshed with the gear 42 on one side close to the mounting plate 31. The length direction of the rack 43 is perpendicular to the length direction of the wing plate 11, and the rack 43 extends toward the second positioning plate 22. A limiting groove 312 is also provided on the side of the mounting plate 31 away from the slide groove 311. The limiting groove 312 is provided along the length direction of the mounting block, and the rack 43 can slide horizontally in the limiting groove 312.

[0045] A connecting block 431 is fixed to one end of the rack 43 close to the second positioning plate 22, and a groove 4311 is provided on the side of the connecting block 431 close to the second positioning plate 22. Two sliding rods 221 are fixed to the side of the second positioning plate 22 away from the connecting rod 23. The two sliding rods 221 are respectively located on the side of the second positioning plate 22 close to the wing plate 11, and the length direction of the sliding rod 221 is perpendicular to the web 12. The connecting block 431 is slidably connected to the sliding rod 221 through the groove 4311. When the size of the I-beam 1 changes, the side of the second positioning plate 22 close to the web 12 can abut against the web 12.

[0046] A limiting block 432 is fixed to one end of the rack 43 away from the connecting block 431 . The limiting block 432 can abut against the gear 42 to reduce the situation where the rack 43 completely escapes from the limiting groove 312 , thereby limiting the sliding distance of the rack 43 .

[0047] A rotating column 421 is vertically fixed to the side of the gear 42 away from the fixing block 41 . The axis of the rotating column 421 is parallel to the axis of the gear 42 , so that the operator can rotate the gear 42 conveniently.

[0048] Reference Figure 4A plug rod 44 and an adjustment component 45 for making the plug rod 44 press against or away from the gear 42 are also slidably installed above the fixed block 41. When the rack 43 moves to a suitable position, the plug rod 44 can press against the gear 42 under the action of the adjustment component 45 to limit the rotation of the gear 42, thereby fixing the position of the rack 43.

[0049] The adjusting assembly 45 includes a fixing plate 451 fixed horizontally on the fixing block 41, and a through hole 4511 is formed on the fixing plate 451. The insertion rod 44 is slidably installed on the fixing plate 451 through the through hole 4511. The axis of the insertion rod 44 is perpendicular to the axis of the gear 42. A fixing ring 452 is coaxially fixed to the end of the insertion rod 44 away from the gear 42. A clamping spring 453 is fixed between the fixing ring 452 and the fixing plate 451, and the clamping spring 453 is sleeved on the outside of the insertion rod 44. One end of the clamping spring 453 is fixed to the fixing ring 452, and the other end is fixedly connected to the fixing plate 451. The clamping spring 453 gives the insertion rod 44 a force to press against the gear 42 to lock the gear 42. When the insertion rod 44 is not needed to lock the gear 42, the gear 42 can be rotated by pulling the fixing ring 452 to make the insertion rod 44 away from the gear 42.

[0050] The implementation principle of the arch frame connection plate positioning mold in the embodiment of the present application is:

[0051] When it is necessary to weld the connecting plate 5 to the end of the I-beam 1, the positioning frame 2 is clamped into one side close to the end of the I-beam 1, and the first positioning plate 21 is clamped in the I-beam 1 through the second positioning plate 22. When the size of the I-beam 1 changes, the locking mechanism 3 is clamped on the wing plate 11 and fixed to the wing plate 11 by the mutual clamping of the first clamping plate 35 and the second clamping plate 36. The adjusting mechanism 4 can adapt to the distance between the second positioning plate 22 and the wing plate 11, and the gear 42 is rotated to realize the sliding of the rack 43, so that the second positioning plate 22 is located between the two wing plates 11, and the second positioning plate 22 is abutted against the web 12. At this time, the position of the first positioning plate 21 is fixed, and the bolts 211 on the first positioning plate 21 are aligned with the threaded holes 51 reserved on the connecting plate 5, and the connecting plate 5 and the I-beam 1 are welded.
