Description

Technical Field

[0001] This invention relates to the field of bridge engineering technology, and in particular to a shuttle construction method for corrugated pipes in precast beam construction. Background Technology

[0002] In traditional precast beam construction, adjusting the position of the corrugated pipe usually requires three workers: two at each end (one pulling and one feeding) and the third in the middle to adjust its position, resulting in low construction efficiency.

[0003] Furthermore, since the corrugated pipe needs to pass through the precast beam from one end and then be pulled back to the other end for fixation, the construction time is relatively long, which will prolong the progress of the entire project. At the same time, when adjusting the position of the corrugated pipe, it is easy to cause inaccurate positioning of the corrugated pipe, which will affect the construction quality. In addition, at least three professional personnel are required to operate at the same time, which increases the construction cost. Therefore, a shuttle construction method for corrugated pipes in precast beam construction is proposed. Summary of the Invention

[0004] To address the technical problems of inconvenient adjustment of corrugated pipe position and low construction efficiency in the existing precast beam construction process, this invention proposes a shuttle construction method for corrugated pipes in precast beam construction.

[0005] The present invention proposes a shuttle construction method for corrugated pipes in precast beam construction, comprising the following construction steps: Step 1: Determine the arrangement of corrugated pipes within the completed steel cage, including the number, spacing, and size of the corrugated pipes, and divide the corrugated pipes distributed from top to bottom into N1, N2, N3, and N4, which are symmetrical from left to right.

[0006] Step 2: Connect the drive mechanism to one end of the bellows using the clamping mechanism.

[0007] Step 3: The first main reinforcing bars are symmetrically distributed in the hollow part of the web of the reinforcing cage as tracks, and the second main reinforcing bars are symmetrically distributed in the hollow part of the bottom plate of the reinforcing cage as tracks. The drive mechanism is equipped with small wheels corresponding to the first or second main reinforcing bars.

[0008] Step 4: The drive mechanism drives the corrugated pipe through the hollow part of the web or bottom plate of the steel cage by moving the small wheels along the surface of the first or second main steel bar.

[0009] Step 5: Fix the surface of the corrugated pipe with the corrugated pipe positioning steel bars.

[0010] Preferably, the clamping mechanism includes a first arc-shaped retaining ring and a second arc-shaped retaining ring in a spliced ​​shape. The inner walls of the first arc-shaped retaining ring and the second arc-shaped retaining ring are respectively provided with arc-shaped grooves in a rectangular array. An arc-shaped retaining plate is fixedly connected to the inner wall of the arc-shaped groove. A square retaining groove is provided on one end surface of the arc-shaped retaining plate, and a retaining block is fixedly connected to the other end of the arc-shaped retaining plate.

[0011] Through the above technical solution, two symmetrically distributed arc-shaped clamping plates are connected together by clamping blocks and square clamping slots. That is, the clamping block on one arc-shaped clamping plate engages with the square clamping slot on the other arc-shaped clamping plate, thereby facilitating the engagement of the arc-shaped clamping plate with the surface of the corrugated pipe.

[0012] Preferably, one end of the first arc retaining ring and the second arc retaining ring are symmetrically provided with circular grooves, and the inner walls of the first arc retaining ring and the second arc retaining ring are symmetrically provided with pushing cylinders. One end of the piston rod of the pushing cylinder is fixedly connected to a circular block, and the surface of the circular block is slidably connected to the inner wall of the circular groove.

[0013] Through the above technical solution, by pushing the cylinder piston rod to extend and retract, the circular block connected to it moves. The movement of the circular block causes it to move along the inner wall of the circular slot, and when the circular block extends into the circular slot, the two first circular arc retaining rings and the second circular arc retaining ring are connected together.

[0014] Preferably, a ring is fixedly installed on the inner wall of the circular block, and two grooves are formed on the surface of the ring. An annular spring is sleeved on the inner wall of each of the two grooves. Movable blocks are sleeved on the surface of the annular springs in an annular array. Limiting grooves are formed in an annular array on the inner surface of the ring. The surface of the movable block is slidably connected to the inner wall of the limiting groove. Through holes are formed in an annular array on the outer surface of the circular block. The surface of the movable block is slidably engaged with the inner wall of the through holes.

[0015] Through the above technical solution, as the piston rod of the pushing cylinder extends, it drives the circular block to insert into the circular slot. This causes the moving block to move along the perforation and inner wall of the circular slot towards the center of the ring under the pressure of the circular slot. This causes the surface of the ring spring to deform and generate elasticity. When the circular block is fully inserted into the circular slot and the pushing cylinder stops running, the elastic force of the ring spring causes the moving block to press against the circular slot, thereby increasing the friction between the moving block and the circular slot and further improving the tightness of the connection between the first and second circular arc retaining rings.

[0016] Preferably, the driving mechanism includes a concave seat that is fixedly installed on the surfaces of the first arc-shaped retaining ring and the second arc-shaped retaining plate, and the inner surface of the concave seat is slidably engaged with the surface of the first main reinforcing bar or the second main reinforcing bar.

[0017] The above technical solution involves installing the drive mechanism on the corrugated pipe using a clamping mechanism, and making the concave seat fit into the surface of the first main reinforcing bar or the second main reinforcing bar.

[0018] Preferably, the small wheel is disposed on the inner surface of the concave seat, and the surface of the small wheel is in contact with the surface of the first main reinforcing bar or the second main reinforcing bar.

[0019] Through the above technical solution, as the concave seat is sleeved with the first main reinforcing bar or the second main reinforcing bar, the small wheel comes into contact with the surface of the first main reinforcing bar or the second main reinforcing bar.

[0020] Preferably, a drive motor is fixedly mounted on the upper surface of the concave seat, one end of the output shaft of the drive motor extends into the concave seat and is fixedly connected to a rotating shaft, and the two ends of the rotating shaft are respectively fixedly sleeved with a first bevel gear.

[0021] Through the above technical solution, the rotation of the output shaft of the drive motor drives the rotating shaft connected to it to rotate, and the rotation of the rotating shaft drives the two first bevel gears connected to it to rotate synchronously.

[0022] Preferably, a drive shaft is fixedly sleeved at the center of the small wheel, and a second bevel gear is fixedly sleeved at the end of the drive shaft away from the small wheel, wherein the surface of the first bevel gear meshes with the surface of the second bevel gear.

[0023] Through the above technical solution, the rotation of the first bevel gear drives the rotation of the second bevel gear meshing with it, and the rotation of the second bevel gear drives the rotation of the pinion connected to it.

[0024] Preferably, a pulley is fixedly sleeved on the surface of the drive shaft near the small wheel, and a transmission belt is drivenly connected to the surfaces of two adjacent pulleys.

[0025] Through the above technical solution, the rotation of the drive shaft drives the transmission belt to rotate through the pulley, thereby enabling the two small wheels located on the same side of the inner surface of the concave seat to move synchronously.

[0026] Preferably, the inner surface of the concave seat has symmetrically distributed storage grooves, and the small wheel is installed in the storage groove through the drive shaft.

[0027] Through the above technical solution, the design of the receiving groove avoids the small wheels occupying too much space, thereby facilitating a closer contact between the concave seat and the first or second main reinforcing bar, which is beneficial for better guiding the movement of the corrugated pipe.

[0028] The beneficial effects of this invention are as follows: 1. By setting a clamping mechanism, it is easy to connect the drive mechanism with the corrugated pipe, so that the N1, N2, and N3 corrugated pipes located in the web of the steel cage can move along the surface of the first main steel bar, and the N4 corrugated pipe located in the bottom plate of the steel cage can move along the surface of the second main steel bar. This facilitates installation and improves the construction efficiency of the corrugated pipe.

[0029] 2. By setting up a driving mechanism, the corrugated pipe can be easily moved, allowing it to move through the steel cage without manual operation. Therefore, during construction, only one worker is needed to complete the work, eliminating the need for multiple professionals. This enables rapid and accurate adjustment and continuous construction of the precast beam corrugated pipe, improving construction efficiency and quality. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Reference Figures 1-12 A shuttle construction method for corrugated pipes in precast beam construction includes the following construction steps: Step 1: Determine the arrangement of the corrugated pipes 2 within the bundled steel cage 1, including the number, spacing, and size of the corrugated pipes 2, and divide the corrugated pipes 2 distributed from top to bottom into N1, N2, N3, and N4, which are symmetrical from left to right.

[0034] Step 2: Connect the drive mechanism to one end of the bellows 2 using the clamping mechanism.

[0035] Step 3: The first main steel bar 5 is symmetrically distributed in the hollow part of the web of the steel cage 1 as a track, and the second main steel bar 6 is symmetrically distributed in the hollow part of the bottom plate of the steel cage 1 as a track. The drive mechanism is equipped with small wheels 4 corresponding to the first main steel bar 5 or the second main steel bar 6.

[0036] Step 4: The drive mechanism drives the corrugated pipe 2 through the hollow part of the web or bottom plate of the steel cage 1 by moving the small wheel 4 along the surface of the first main steel bar 5 or the second main steel bar 6.

[0037] Step 5: Fix the surface of corrugated pipe 2 with the corrugated pipe positioning steel bar.

[0038] To connect the drive mechanism to the bellows 2, the clamping mechanism includes a first arc-shaped retaining ring 3 and a second arc-shaped retaining ring 301 in a spliced ​​shape. The inner walls of the first arc-shaped retaining ring 3 and the second arc-shaped retaining ring 301 are respectively provided with arc-shaped grooves 302 in a rectangular array. An arc-shaped retaining plate 303 is fixedly connected to the inner wall of the arc-shaped groove 302. A square retaining groove 304 is provided on one end surface of the arc-shaped retaining plate 303. A retaining block 305 is fixedly connected to the other end of the arc-shaped retaining plate 303. The two symmetrically distributed arc-shaped retaining plates 303 are connected together by the connection between the retaining block 305 and the square retaining groove 304. That is, the retaining block 305 on one arc-shaped retaining plate 303 engages with the square retaining groove 304 on the other arc-shaped retaining plate 303, thereby facilitating the engagement of the arc-shaped retaining plate 303 with the surface of the bellows 2.

[0039] To connect the first arc retaining ring 3 and the second arc retaining ring 301 together, circular grooves 306 are symmetrically provided at one end of both the first arc retaining ring 3 and the second arc retaining ring 301. Push cylinders 307 are symmetrically distributed on the inner walls of both the first arc retaining ring 3 and the second arc retaining ring 301. A circular block 308 is fixedly connected to one end of the piston rod of the push cylinder 307. The surface of the circular block 308 is slidably connected to the inner wall of the circular groove 306. The extension and retraction of the piston rod of the push cylinder 307 drives the circular block 308 connected to it to move. The movement of the circular block 308 causes it to move along the inner wall of the circular groove 306. When the circular block 308 extends into the circular groove 306, the two first arc retaining rings 3 and the second arc retaining ring 301 are connected together.

[0040] To further improve the tightness of the connection between the first arc retaining ring 3 and the second arc retaining ring 301, a circular ring 309 is fixedly installed on the inner wall of the circular block 308. Two grooves 310 are formed on the surface of the circular ring 309, and annular springs 311 are sleeved on the inner walls of both grooves 310. Moving blocks 312 are sleeved on the surface of the annular springs 311 in a circular array. Limiting grooves 313 are formed on the inner surface of the circular ring 309 in a circular array, and the surface of the moving blocks 312 is slidably connected to the inner wall of the limiting grooves 313. Through holes 314 are formed on the outer surface of the circular block 308 in a circular array, and the surface of the moving blocks 312 is slidably connected to the inner wall of the limiting grooves 313. The inner wall of the hole 314 slides and engages. As the piston rod of the push cylinder 307 extends, it drives the circular block 308 to insert into the circular slot 306. This causes the moving block 312 to move along the inner wall of the hole 314 and the circular slot 306 towards the axis of the ring 309 under the pressure of the circular slot 306. This causes the surface of the ring spring 311 to deform and generate elasticity. When the circular block 308 is fully inserted into the circular slot 306 and the push cylinder 307 stops running, the elastic force of the ring spring 311 drives the moving block 312 to press the circular slot 306, thereby increasing the friction between the moving block 312 and the circular slot 306.

[0041] By setting a clamping mechanism, it is easy to connect the drive mechanism with the corrugated pipe 2, so that the N1, N2, and N3 corrugated pipes 2 located in the web of the steel cage 1 can move along the surface of the first main steel bar 5, and the N4 corrugated pipe 2 located in the bottom plate of the steel cage 1 can move along the surface of the second main steel bar 6. This facilitates installation and improves the construction efficiency of the corrugated pipe 2.

[0042] To facilitate contact between the driving mechanism and the first main reinforcing bar 5 or the second main reinforcing bar 6, the driving mechanism includes a concave seat 401 that is fixedly installed on the surfaces of the first arc retaining ring 3 and the second arc retaining plate 303, respectively. The inner surface of the concave seat 401 is slidably engaged with the surface of the first main reinforcing bar 5 or the second main reinforcing bar 6. The driving mechanism is installed on the corrugated pipe 2 by a clamping mechanism, so that the concave seat 401 is sleeved with the surface of the first main reinforcing bar 5 or the second main reinforcing bar 6.

[0043] In order to make the small wheel 4 contact the first main steel bar 5 or the second main steel bar 6, a concave seat 401 is provided on the inner surface of the small wheel 4, and the surface of the small wheel 4 contacts the surface of the first main steel bar 5 or the second main steel bar 6. As the concave seat 401 is sleeved with the first main steel bar 5 or the second main steel bar 6, the small wheel 4 contacts the surface of the first main steel bar 5 or the second main steel bar 6.

[0044] To drive the pinion 4 to rotate, a drive motor 402 is fixedly installed on the upper surface of the concave seat 401. One end of the output shaft of the drive motor 402 extends into the concave seat 401 and is fixedly connected to a rotating shaft 403. First bevel gears 404 are fixedly sleeved at both ends of the rotating shaft 403. A drive shaft 405 is fixedly sleeved at the center of the pinion 4. A second bevel gear 406 is fixedly sleeved at the end of the drive shaft 405 away from the pinion 4. The surfaces of the first bevel gears 404 and the second bevel gears 406 mesh. The rotation of the output shaft of the drive motor 402 drives the rotating shaft 403 connected to it to rotate. The rotation of the rotating shaft 403 drives the two first bevel gears 404 connected to it to rotate synchronously. The rotation of the first bevel gears 404 drives the second bevel gear 406 meshing with them to rotate. The rotation of the second bevel gear 406 drives the pinion 4 connected to it to rotate. The distribution of the first bevel gears and the second bevel gears makes the pinion 4 rotate synchronously.

[0045] In order to drive multiple small wheels 4 to rotate synchronously, a pulley 407 is fixedly sleeved on the surface of the drive shaft 405 near the small wheel 4. A transmission belt 408 is connected to the surfaces of two adjacent pulleys 407. At the same time, the rotation of the drive shaft 405 drives the transmission belt 408 to rotate through the pulley 407, thereby causing the two small wheels 4 located on the same side of the inner surface of the concave seat 401 to move synchronously.

[0046] To avoid the small wheel 4 taking up too much space, storage slots 409 are symmetrically distributed on the inner surface of the concave seat 401, and the small wheel 4 is installed in the storage slots 409 through the drive shaft 405.

[0047] By setting up a driving mechanism, the corrugated pipe 2 can be easily moved, thus allowing it to move through the steel cage 1 without manual operation. Therefore, during construction, only one worker is needed to complete the work, eliminating the need for multiple professionals. This enables rapid and accurate adjustment and continuous construction of the precast beam corrugated pipe 2, improving construction efficiency and quality.

[0048] Working principle: In use, the first arc retaining ring 3 and the second arc retaining ring 301 are aligned and brought close together, so that the arc retaining plates 303 on the first arc retaining ring 3 and the second arc retaining ring 301 are spliced ​​together, that is, the retaining block 305 on the arc retaining plate 303 is engaged with the square retaining groove 304 on the other arc retaining plate 303. After the first arc retaining ring 3 and the second arc retaining ring 301 are in contact, the push cylinder 307 is activated. By pushing the piston rod of the push cylinder 307 to extend, the circular block 308 connected to it is moved. The movement of the circular block 308 causes it to enter the circular retaining groove 306 and move along the inner wall of the circular retaining groove 306. When the circular block 308 extends into the circular retaining groove 306, the two first arc retaining rings 3 and the second arc retaining ring 301 are connected together. Simultaneously, as the circular block 308 extends into the circular slot 306, the moving block 312 moves along the inner wall of the perforation 314 and the circular slot 306 towards the axis of the ring 309 under the pressure of the circular slot 306. Thus, the movement of the moving block 312 causes the surface of the ring spring 311 to deform and generate elasticity. When the circular block 308 is fully inserted into the circular slot 306 and the cylinder 307 stops running, the elastic force of the ring spring 311 drives the moving block 312 to press the circular slot 306, thereby increasing the friction between the moving block 312 and the circular slot 306, which facilitates the tight connection between the first arc retaining ring 3 and the second arc retaining ring 301. Then, the concave seat 401 is fitted onto the first main reinforcing bar 5 or the second main reinforcing bar 6, so that the small wheel 4 in the receiving groove 409 of the concave seat 401 contacts the surface of the first main reinforcing bar 5 or the second main reinforcing bar 6. Then, the drive motor 402 is started. The rotation of the output shaft of the drive motor 402 drives the rotating shaft 403 connected to it to rotate. The rotation of the rotating shaft 403 drives the two first bevel gears 404 connected to it to rotate synchronously. The rotation of the first bevel gear 404 drives the second bevel gear 406 meshing with it to rotate. The rotation of the second bevel gear 406 drives the small wheel 4 connected to it to rotate. The distribution of the first bevel gear and the second bevel gear makes the small wheel 4 rotate synchronously. At the same time, the rotation of the drive shaft 405 drives the conveyor belt 408 to rotate through the pulley 407, thereby making the two small wheels 4 located on the same side of the inner surface of the concave seat 401 move synchronously. The rotation of the small wheel 4 drives the corrugated pipe 2 to move along the surface of the first main reinforcing bar 5 or the second main reinforcing bar 6, so that the corrugated pipe 2 can shuttle in the reinforcing cage 1.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
