Description

Technical Field

[0001] This invention belongs to the field of bridge prefabricated segment technology, and particularly relates to a high-precision positioning and splicing auxiliary device for bridge prefabricated segments. Background Technology

[0002] The "Technical Specification for Construction of Precast Segment Assembly of Prestressed Concrete Bridges" includes chapters on general principles, terminology, construction preparation, segment precasting, segment transportation, assembling precast segments span by span, bridge erection machine operation, and measurement control.

[0003] Based on the Shanghai Xinliuliqiao project, the regulations propose a span-by-span construction method using bridge erection machines, employing novel prestressed materials and construction technologies, and verifying these through precast segmental beam tests. The content covers material combinations for prestressed segmental concrete box girder bridges within the accelerated bridge construction technology system, involving technical issues such as shear stud connections and composite beam behavior analysis. The study considers creep and shrinkage effects, employing the effective modulus method and equivalent nodal loads for structural analysis.

[0004] Currently, precast bridge segments are typically manufactured using molds and then lifted and installed using gantry cranes. However, during on-site installation, deviations in the environment and road conditions can prevent the normal high-precision assembly of precast bridge segments. Therefore, we propose a high-precision positioning and assembly auxiliary device for precast bridge segments. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision positioning and splicing auxiliary device for prefabricated bridge segments to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a high-precision positioning and splicing auxiliary device for precast bridge segments, comprising:

[0007] The foundation and concrete base, the concrete base being located on top of the foundation, a flat plate being provided on the foundation and on both sides of the concrete base, a baffle being provided on each of the two flat plates, the baffle being connected to a vertical plate via an inclined plate, and the vertical plate being connected to a fence via a bearing plate;

[0008] Two adjustment components are respectively disposed on two flat plates and are used to adjust the angle of rotation of the baffle on the flat plates;

[0009] The first and second back-shaped plates are located between two baffles. The top of the first and second back-shaped plates are respectively provided with top plate one and top plate two. A fixing frame is provided on one side of the second back-shaped plate, and a degree measuring instrument is fixedly installed on the top of the fixing frame.

[0010] A bridge mold is provided, which is set between a first back-shaped plate and a second back-shaped plate. An L-shaped plate is symmetrically and rotatably installed on the bottom side of the bridge mold, and a rotating plate is rotatably installed on one side of each of the two L-shaped plates.

[0011] Two control components are provided, both of which are mounted on the bridge mold and are used to control the rotation of the two L-shaped plates and the two rotating plates.

[0012] A traction assembly, which is mounted on the foundation and is used to move two flat plates and a fixed frame.

[0013] In the above technical solution, the baffle, inclined plate, vertical plate, bearing plate and fence are integrally formed structures, and the first and second U-shaped plates are located on top of the concrete base.

[0014] In this technical solution, the structural stability of the baffle, inclined plate, vertical plate, load-bearing plate, and fence is ensured. After the concrete is poured onto the steel reinforcement frame, personnel can stand on the load-bearing plate and use a concrete vibrator to compact the concrete on the steel reinforcement frame, ensuring the quality of the precast bridge segments. The fence serves a protective function.

[0015] In the above technical solution, the adjustment component further includes:

[0016] A plurality of U-shaped plates are fixedly installed on one side of the baffle, and the top of the plurality of U-shaped plates is in contact with the inclined plate. A plurality of grid plates are fixedly installed inside the U-shaped plates.

[0017] A plurality of fixed shafts are fixedly installed on the bottom of a plurality of U-shaped plates, and a plurality of bases are fixedly installed on the top of the plate, and the plurality of U-shaped plates are rotatably installed in the plurality of bases.

[0018] A plurality of bases two, all of which are fixedly mounted on a flat plate, and a rotating shaft one is rotatably mounted inside each of the plurality of bases two. A hydraulic cylinder one is fixedly mounted on the rotating shaft one, and a rotating shaft two is fixedly mounted on the other end of the hydraulic cylinder one.

[0019] Several rectangular slots are respectively opened on several U-shaped plates, and the rotating shaft is rotatably installed in the rectangular slots.

[0020] In this technical solution, the cooperation between the U-shaped plate and the grid plate ensures that the structure of the U-shaped plate is more stable, while the U-shaped plate can provide support for the baffle and the inclined plate.

[0021] When the baffle needs to rotate, several hydraulic cylinders can be powered on and started simultaneously. One end of each hydraulic cylinder is fixed to the base via a rotating shaft, while the other end is fixed in a rectangular groove via a rotating shaft. When the hydraulic cylinder retracts, the other end pulls the U-shaped plate through the rotating shaft, causing the fixed shaft to rotate in the base. At the same time, the U-shaped plate also rotates the baffle, inclined plate, vertical plate, bearing plate, and fence together, making the baffle tilted. When the hydraulic cylinder extends, the other end pushes the U-shaped plate through the rotating shaft, causing the fixed shaft to rotate in the base. At the same time, the U-shaped plate also rotates the baffle, inclined plate, vertical plate, bearing plate, and fence together, until the baffle is perpendicular to the flat plate.

[0022] In the above technical solution, the fixed shaft, the U-shaped plate, and the grid plate are integrally formed, the flat plate, the base one, and the base two are integrally formed, and the U-shaped plate, the baffle, and the inclined plate are integrally formed.

[0023] In this technical solution, the structural stability of the fixed shaft, the U-shaped plate, and the grid plate is ensured; the structural stability of the flat plate, the base one, and the base two is ensured; and the structural stability of the U-shaped plate, the baffle, and the inclined plate is ensured.

[0024] In the above technical solution, the control component further includes:

[0025] A plurality of fixed seats 1 are fixedly installed on the inner wall of the bridge mold. A rotating column 1 is rotatably installed inside the fixed seat 1. A hydraulic cylinder 2 is fixedly installed on the rotating column 1. A rotating column 2 is fixedly installed at one end of the hydraulic cylinder 2.

[0026] A plurality of rotating slots are provided on an L-shaped plate, and a plurality of rotating columns are respectively rotatably installed in the plurality of rotating slots.

[0027] A plurality of fixed seats 2 are fixedly mounted on an L-shaped plate. A rotating column 3 is rotatably mounted on the fixed seat 2. A hydraulic cylinder 3 is fixedly mounted on the rotating column 3. A rotating column 4 is fixedly mounted on one end of the hydraulic cylinder 3.

[0028] A plurality of rotating slots 2 are provided on a rotating plate, and a plurality of rotating columns 4 are respectively rotatably installed in the plurality of rotating slots 2;

[0029] A concrete curing tester is fixedly installed at the bottom of a bridge mold.

[0030] In this technical solution, the concrete solidification detector can ensure whether the concrete on the steel reinforcement frame has solidified, and can also detect where the concrete on the steel reinforcement frame has not been filled and compacted.

[0031] After the concrete on the steel frame has solidified, personnel can connect and start several hydraulic cylinders (both type 2 and type 3). First, one end of hydraulic cylinder 3 is confined within fixed seat 2 by rotating column 3, and the other end of hydraulic cylinder 3 is confined within rotating groove 2 by rotating column 4. The other end of hydraulic cylinder 3 retracts first, driving the rotating plate to rotate via rotating column 4.

[0032] Subsequently, one end of the hydraulic cylinder 2 is restricted in the fixed seat 1 by the rotating column 1, and the other end of the hydraulic cylinder 2 is restricted in the rotating groove 1 by the rotating column 2. Then, the other end of the hydraulic cylinder 2 retracts and drives the L-shaped plate to rotate through the rotating column 2. Then, the personnel pull the bridge mold, which can be removed from the bridge prefabricated segment.

[0033] When the bridge mold is placed on the steel reinforcement frame, the other end of hydraulic cylinder two first retracts and drives the L-shaped plate to rotate through rotating column two. Then, the other end of hydraulic cylinder three extends and drives the rotating plate to rotate through rotating column four, ensuring that one side of the two rotating plates touches each other.

[0034] In the above technical solution, the first fixing seat and the bridge mold are integrally formed, and the second fixing seat and the L-shaped plate are integrally formed.

[0035] 7. The high-precision positioning and splicing auxiliary device for precast bridge segments according to claim 1, characterized in that, the

[0036] In this technical solution, the structural stability of the fixed seat one and the bridge mold is ensured, and the structural stability of the fixed seat two and the L-shaped plate is guaranteed.

[0037] In the above technical solution, the traction component further includes:

[0038] A shielding platform is fixedly installed on a concrete base. Two sliding grooves are provided on the bottom of the platform, and guide rails fixed to the concrete base are slidably installed in the sliding grooves.

[0039] Two limiting rails are symmetrically arranged at the bottom of the bridge mold, and one end of each limiting rail passes through the mold plate and is fixed to the shielding platform.

[0040] Two frames are symmetrically fixedly installed on the foundation and located inside the shielding platform. A motor is fixedly installed on each frame. A wire roller is fixedly installed on the output shaft of the motor. A wire is wound on the wire roller. One end of the wire is fixed to the fixed frame.

[0041] Two frames are symmetrically fixedly installed on the foundation and located inside the shielding platform. A motor is fixedly installed on each frame. A wire roller is fixedly installed on the output shaft of the motor. A wire is wound on the wire roller. One end of the wire is fixed to the plate.

[0042] In this technical solution, one end of each of the two limiting rails is located in the bridge mold and the second mold plate, which can limit the bridge mold and the second mold plate and ensure the structural stability of the bridge mold and the second mold plate.

[0043] When motor one and motor two are connected to the power supply and started, the output shaft of motor one will drive the steel wire roller one to rotate. The rotating steel wire roller one will wrap the steel wire one on the steel wire roller one and cause the steel wire one to drive the fixed frame and the return plate two to move.

[0044] The output shaft of motor two will drive wire roller two to rotate. The rotating wire roller two will wrap the wire two around the wire roller two and cause the wire two to move the plate on the guide rail.

[0045] In the above technical solution, the guide rail is further fixed to the concrete base by expansion bolts, the limiting rail is fixed to the shielding platform by expansion bolts, and both frame one and frame two are fixed to the concrete base by expansion bolts.

[0046] In this technical solution, the guide rail is stably fixed on the concrete base, ensuring the structural stability of the limit rail and the shielding platform, and ensuring the structural stability of frame one and frame two on the concrete base.

[0047] In the above technical solution, furthermore, the second retaining plate is tightly welded to the fixing frame, and the distance between the two sides of the bridge mold and the baffle is 50-90cm; the distance between the bridge mold and the first and second retaining plates is 50-90cm; and the distance between the rotating plate and the concrete base is 50-90cm.

[0048] In this technical solution, the steel reinforcement frame is designed to enclose the bridge mold, L-shaped plate, and rotating plate, while the concrete is poured onto the steel reinforcement frame, allowing the thickness of the precast bridge segments to reach 50-90cm.

[0049] In the above technical solution, the second type of U-shaped plate is further welded tightly to the fixed frame.

[0050] In this technical solution, the structural stability of the second profile plate and the fixing frame is ensured.

[0051] The beneficial effects of this invention are:

[0052] This high-precision positioning and splicing auxiliary device for precast bridge segments utilizes a combination of a flat plate, baffle, inclined plate, vertical plate, U-shaped plate one, top plate one, U-shaped plate two, top plate two, fixing frame, flatness detector, bridge mold, L-shaped plate, and rotating plate. This ensures that personnel can first fix U-shaped plate one to the concrete base using expansion bolts and reinforcing bars. Then, the assembled reinforcing bar frame is placed on one side of U-shaped plate one. Simultaneously, the bridge mold, L-shaped plate, and rotating plate are placed within the reinforcing bar frame, ensuring U-shaped plate two is tightly attached to it. The baffle is then rotated on the flat plate using an adjusting component until it is tightly attached to the reinforcing bar frame, U-shaped plate one, top plate one, U-shaped plate two, and top plate two, with the baffle perpendicular to the flat plate. Finally, personnel can proceed with the assembly of the flat plate, baffle, inclined plate, vertical plate, U-shaped plate one, top plate one, U-shaped plate two, and top plate two. The surface is coated with anti-stick paint to prevent difficulty in removing the concrete after it has hardened. Then, personnel use bolts to fix the baffle, U-shaped plate one, and U-shaped plate two together. Next, the mixed concrete is poured onto the reinforcing frame, and a concrete vibrator is used to compact the concrete. The height of the concrete is checked using a leveling instrument to ensure that the precast bridge segments are installed on the concrete base. After the concrete on the reinforcing frame has hardened, the bolts on the baffle, U-shaped plate one, and U-shaped plate two are removed using a wrench, and the baffle is rotated away from the bridge formwork using an adjusting assembly. Simultaneously, the traction assembly moves two flat plates and a fixed frame, at which point the complete precast bridge segment is created. The moving flat plate is located at the end of the precast bridge segment, and one side of the second shaped plate and the second top plate on the fixed frame are flush with one side of the baffle. Then, the assembled new steel reinforcement frame is placed between the precast bridge segment and the second shaped plate. The control assembly controls the rotation of the two L-shaped plates and the two rotating plates, facilitating the removal of the bridge mold from the complete precast bridge segment into the new steel reinforcement frame. Subsequently, the adjustment assembly controls the rotation of the baffle on the flat plate until the baffle is tight. After attaching the new steel reinforcement frame, U-shaped plate two, and top plate two to ensure the entire assembly is installed perfectly without any errors, the baffle and U-shaped plate two are then fixed together with bolts. Subsequently, the mixed concrete is poured onto the new steel reinforcement frame, and the concrete on the frame is compacted using a concrete vibrator. The height of the concrete is then checked using a compaction tester to ensure that the new precast bridge segments are installed on the concrete base. The above operations are then repeated to ensure that the precast bridge segments are spliced ​​with high precision each time they are assembled, without deviations due to the site environment or road conditions.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0066] Example 1: This example provides a high-precision positioning and splicing auxiliary device for precast bridge segments, including:

[0067] The foundation 1 and the concrete base 11 are located on top of the foundation 1. Flat plates 2 are provided on both sides of the foundation 1 and the concrete base 11. Baffles 21 are provided on both flat plates 2. The baffles 21 are connected to vertical plates 23 through inclined plates 22. The vertical plates 23 are connected to fences 25 through bearing plates 24.

[0068] Two adjustment components are respectively set on two flat plates 2, and are used to adjust the angle of rotation of the baffle 21 on the flat plate 2;

[0069] The first type of the return plate 3 and the second type of the return plate 32 are located between two baffles 21. The top of the first type of the return plate 3 and the second type of the return plate 32 are respectively provided with a top plate 31 and a top plate 33. A fixing frame 4 is provided on one side of the second type of the return plate 32. A straightness detector 41 is fixedly installed on the top of the fixing frame 4.

[0070] Bridge mold 5 is set between the first return plate 3 and the second return plate 32. L-shaped plates 6 are symmetrically and rotatably installed on the bottom side of the bridge mold 5. Rotating plates 7 are rotatably installed on one side of each of the two L-shaped plates 6.

[0071] Two control components are installed on the bridge mold 5 and are used to control the rotation of the two L-shaped plates 6 and the two rotating plates 7.

[0072] The traction assembly is mounted on the foundation 1 and is used to move the two flat plates 2 and the fixed frame 4.

[0073] The system comprises a flat plate 2, baffle 21, inclined plate 22, vertical plate 23, U-shaped plate 3, top plate 31, U-shaped plate 32, top plate 33, fixing frame 4, flatness tester 41, bridge mold 5, L-shaped plate 6, and rotating plate 7. The system ensures that personnel can first fix U-shaped plate 3 to the concrete base 11 using expansion bolts and reinforcing bars. Then, the assembled reinforcing bar frame is placed on one side of U-shaped plate 3. Simultaneously, the bridge mold 5, L-shaped plate 6, and rotating plate 7 are placed within the reinforcing bar frame, ensuring that U-shaped plate 32 is tightly attached to it. The baffle 21 is rotated on the flat plate 2 using an adjusting component until it is tightly attached to the reinforcing bar frame, U-shaped plate 3, top plate 31, U-shaped plate 32, and top plate 33, with the baffle 21 perpendicular to the flat plate 2. Finally, personnel can move freely between the flat plate 2, baffle 21, inclined plate 22, vertical plate 23, U-shaped plate 3, and top plate 7. The surfaces of baffle 21, U-shaped plate 32, and top plate 33 are coated with anti-stick paint to prevent them from being difficult to remove after the concrete has hardened. Then, personnel use bolts to fix baffle 21, U-shaped plate 32, and top plate 33 together. Next, the mixed concrete is poured onto the reinforcing frame, and the concrete is compacted using a concrete vibrator. The height of the concrete is checked using a leveling instrument 41 to ensure that the precast bridge segments are installed on the concrete base 11. After the concrete on the reinforcing frame has hardened, the bolts on baffle 21, U-shaped plate 32, and top plate 33 are removed using a wrench, and the baffle 21 is adjusted using an adjusting assembly. The plate 2 rotates away from the bridge mold 5. Simultaneously, the traction assembly moves the two plate 2s and the fixing frame 4. At this point, the complete precast bridge segment is produced, and the moving plate 2 is located at the tail end of the precast bridge segment. One side of the second shaped plate 32 and the second top plate 33 on the fixing frame 4 is flush with one side of the baffle 21. Then, the assembled new steel reinforcement frame is placed between the precast bridge segment and the second shaped plate 32. The control assembly controls the rotation of the two L-shaped plates 6 and the two rotating plates 7, facilitating the removal of the bridge mold 5 from the complete precast bridge segment into the new steel reinforcement frame. Subsequently, the adjustment assembly controls the baffle 21 on the plate 2. Rotate until the baffle 21 is tightly attached to the new steel reinforcement frame, the U-shaped plate 2 32, and the top plate 2 33, ensuring that the entire device is installed perfectly without any errors. Then, fix the baffle 21 and the U-shaped plate 2 32 together with bolts. Subsequently, the personnel pour the mixed concrete into the new steel reinforcement frame and compact the concrete on the steel reinforcement frame with a concrete vibrator. The height of the concrete is checked with a straightness detector 41 to ensure that the new precast bridge segment is installed on the concrete base 11. Then, repeat the above operation to ensure that the precast bridge segments are spliced ​​with high precision each time they are installed together, without deviation due to the site environment and road conditions.

[0075] The structure of the baffle 21, inclined plate 22, vertical plate 23, bearing plate 24, and fence 25 is ensured to maintain structural stability. After the concrete is poured onto the steel reinforcement frame, personnel can stand on the bearing plate 24 and use a concrete vibrator to compact the concrete on the steel reinforcement frame, ensuring the quality of the precast bridge segments. The fence 25 serves a protective function.

[0076] Example 3: This example provides a high-precision positioning and splicing auxiliary device for precast bridge segments. In addition to the technical solutions described in the above examples, it also has the following technical features: the adjustment components include:

[0077] Several U-shaped plates 26 are fixedly installed on one side of the baffle 21, and the top of the U-shaped plates 26 contacts the inclined plate 22. Several grid plates 261 are fixedly installed inside the U-shaped plates 26.

One end of each hydraulic cylinder 282 is fixed to the base 28 via a rotating shaft 281, while the other end is fixed to the rectangular groove 263 via a rotating shaft 283. When the hydraulic cylinder 282 retracts, the other end of the hydraulic cylinder 282 pulls the U-shaped plate 26 via the rotating shaft 283, causing the fixed shaft 262 to rotate within the base 27. Simultaneously, the U-shaped plate 26 also drives... The baffle 21, inclined plate 22, vertical plate 23, bearing plate 24 and fence 25 rotate together, so that the baffle 21 is in an inclined state. When the hydraulic cylinder 282 extends, the other end of the hydraulic cylinder 282 pushes the U-shaped plate 26 through the rotating shaft 283 to drive the fixed shaft 262 to rotate in the base 27. At the same time, the U-shaped plate 26 also drives the baffle 21, inclined plate 22, vertical plate 23, bearing plate 24 and fence 25 to rotate together until the baffle 21 is perpendicular to the plate 2.

[0086] Several fixed seats 62 are fixedly installed on the inner wall of the bridge mold 5. A rotating column 621 is rotatably installed inside the fixed seat 62. A hydraulic cylinder 63 is fixedly installed on the rotating column 621. A rotating column 64 is fixedly installed at one end of the hydraulic cylinder 63.

[0087] Several rotating slots 61 are provided on the L-shaped plate 6, and several rotating columns 64 are respectively rotatably installed in the several rotating slots 61.

[0088] Several fixed seats 2 65 are fixedly installed on the L-shaped plate 6. A rotating column 3 651 is rotatably installed on the fixed seat 2 65. A hydraulic cylinder 3 66 is fixedly installed on the rotating column 3 651. A rotating column 4 67 is fixedly installed at one end of the hydraulic cylinder 3 66.

[0090] The concrete curing tester 51 is fixedly installed at the bottom of the bridge mold 5.

[0091] Among them, the concrete solidification detector 51 can ensure whether the concrete on the steel reinforcement frame has solidified, and can also detect where the concrete on the steel reinforcement frame has not been filled and compacted.

[0092] After the concrete on the steel frame has solidified, personnel can connect and start several hydraulic cylinders 63 (second) and 66 (third). First, one end of hydraulic cylinder 66 (third) is restricted within fixed seat 65 by rotating column 651, and the other end is restricted within rotating groove 71 by rotating column 67 (fourth). The other end of hydraulic cylinder 66 (third) retracts first, and the rotating plate 7 (fourth) rotates through rotating column 67.

Then, the other end of hydraulic cylinder 2 63 retracts and drives L-shaped plate 6 to rotate through rotating column 2 64.

[0111] Working principle:

[0112] Personnel can first fix the U-shaped plate 3 to the concrete base 11 using expansion bolts and reinforcing bars. Then, the assembled reinforcing bar frame is placed on one side of the U-shaped plate 3. Simultaneously, the bridge mold 5, L-shaped plate 6, and rotating plate 7 are placed in the reinforcing bar frame, ensuring the U-shaped plate 32 is tightly attached to it. The baffle 21 is then rotated on the flat plate 2 using the adjusting assembly until it is tightly attached to the reinforcing bar frame, U-shaped plate 3, top plate 31, U-shaped plate 32, and top plate 33, with the baffle 21 perpendicular to the flat plate 2. Subsequently, personnel can then... 31. The surfaces of the second type of retaining plate 32 and the second type of top plate 33 are coated with anti-stick paint to prevent them from being difficult to remove after the concrete has hardened. Then, the personnel use bolts to fix the baffle 21, the first type of retaining plate 3, and the second type of retaining plate 32 together. After that, the personnel pour the mixed concrete onto the steel reinforcement frame and use a concrete vibrator to compact the concrete on the steel reinforcement frame. The height of the concrete is checked using a leveling instrument 41 to ensure that the precast bridge segment is installed on the concrete base 11. After the concrete on the steel reinforcement frame has hardened, the bolts on the baffle 21, the first type of retaining plate 3, and the second type of retaining plate 32 are removed with a wrench, and the baffle 21 is leveled using the adjusting assembly. The plate 2 rotates away from the bridge mold 5. Simultaneously, the traction assembly moves the two plate 2s and the fixing frame 4. At this point, the complete precast bridge segment is produced, and the moving plate 2 is located at the tail end of the precast bridge segment. One side of the loop plate 22 and the top plate 23 on the fixing frame 4 is flush with one side of the baffle 21. Then, the personnel place the assembled new steel reinforcement frame between the precast bridge segment and the loop plate 22. The control assembly controls the rotation of the two L-shaped plates 6 and the two rotating plates 7, making it easy for the personnel to remove the bridge mold 5 from the complete precast bridge segment into the new steel reinforcement frame. Subsequently, the personnel control the baffle 21 on the plate 2 through the adjustment assembly. Rotate until the baffle 21 is tightly attached to the new steel reinforcement frame, the U-shaped plate 2 32, and the top plate 2 33, ensuring that the entire device is installed perfectly without any errors. Then, fix the baffle 21 and the U-shaped plate 2 32 together with bolts. Subsequently, the personnel pour the mixed concrete into the new steel reinforcement frame and compact the concrete on the steel reinforcement frame with a concrete vibrator. The height of the concrete is checked with a straightness detector 41 to ensure that the new precast bridge segment is installed on the concrete base 11. Then, repeat the above operation to ensure that the precast bridge segments are spliced ​​with high precision each time they are installed together, without deviation due to the site environment and road conditions.
