Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a manufacturing device for a prestressed fiber braided mesh reinforced concrete slab. Background Art

[0002] A manufacturing device for a prestressed fiber braided mesh reinforced concrete slab is a device specifically designed for manufacturing a prestressed fiber braided mesh reinforced concrete slab. Such a device generally includes an anchoring end and a tensioning end. The anchoring end contains an anchoring device for fixing one end of the fiber braided mesh; the tensioning end includes an anchoring device and a pre-tensioning device for tensioning the fiber braided mesh and applying prestress. The pre-tensioning device is connected to the total tensioning device, and by precisely controlling the tensile force, it ensures that each fiber bundle of the fiber braided mesh is subjected to uniform and consistent prestress.

[0003] When fixing the fiber bundle, usually a single mechanical clamping or bonding fixing method is adopted, which is likely to cause the fiber bundle to become loose in the initial stage due to factors such as equipment vibration. And when tensioning the fiber bundle, it may break due to reasons such as a relatively fast tensioning speed or internal defects of the fiber bundle. The broken fiber bundle then entangles with other fiber bundles, affecting the operation. Therefore, a manufacturing device for a prestressed fiber braided mesh reinforced concrete slab is proposed. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks in the prior art that usually a single mechanical clamping or bonding fixing method is adopted, which is likely to cause the fiber bundle to become loose in the initial stage, and when tensioning the fiber bundle, it may break due to reasons such as a relatively fast tensioning speed or internal defects of the fiber bundle, and the broken fiber bundle then entangles with other fiber bundles, and to propose a manufacturing device for a prestressed fiber braided mesh reinforced concrete slab.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A manufacturing device for a prestressed fiber woven mesh reinforced concrete slab, comprising a base. On the upper part of the base, movable plates are symmetrically and slidably arranged. On the upper part of the base, cylinders are symmetrically installed. The output end of the cylinder is fixedly connected to the movable plate. On the upper part of the base, a plurality of round rods are symmetrically and slidably arranged. A fixing component is arranged on the round rod. The fixing component includes a first arc-shaped plate and a second arc-shaped plate respectively rotatably connected to the end part of the round rod, a fixing belt installed at the end part of the round rod, a first threaded rod rotatably connected to the inner side of the round rod, and a movable block slidably arranged on the inner side of the round rod. A rotating plate is installed at the end of the first threaded rod. The rotating plate is movably connected to the movable plate. The movable block is fixedly connected to the fixing belt. A ring is movably connected to the end of the round rod. The fiber bundle passes through the ring and is placed between the first arc-shaped plate and the second arc-shaped plate. Rotating the first threaded rod drives the movable block to move. The movable block moves to tighten the fixing belt to squeeze the fiber bundle, and the fixing belt drives the first arc-shaped plate and the second arc-shaped plate to rotate towards each other and clamp the fiber bundle, so that the fiber bundle is firmly clamped, ensuring that there is no sliding of the fiber bundle during the pulling process;

[0007] A servo motor is installed on the inner side of the round rod. A sensor is installed at the end of the servo motor. The sensor is movably connected to the ring. After the fiber bundle is broken and the sensor senses it, the servo motor is started to drive the ring to move to the inner side of the round rod, and at the same time drive the fiber bundle to contract, avoiding the fiber bundle from breaking and entangling with other fiber bundles.

The movable plate moves under the guidance of the telescopic rods.

[0010] A second threaded rod is rotatably connected to the side of the rotating plate close to the movable plate. The second threaded rod is threadedly connected to the movable plate. The acting force generated when the second threaded rod rotates drives the round rod to move.

[0011] A square plate is installed on the upper part of the round rod. The square plate and the round rod are jointly slidably connected to the base. The round rod slides under the guidance of the square plate.

[0012] A fixing belt is installed on the inner side of the round rod. The fixing belt is slidably connected to the movable block. When the movable block moves, it drives the fixing belt to move and tighten it.

[0013] A support plate is installed at the end of the round rod, a rotating rod is installed on the outer side of the support plate, both the first arc-shaped plate and the second arc-shaped plate are rotatably connected to the rotating rod, a torsion spring is jointly installed between the first arc-shaped plate and the second arc-shaped plate, and the first arc-shaped plate and the second arc-shaped plate rotate towards each other to clamp the fiber bundle.

[0014] Rubber blocks are installed on one side of the fixing belt close to the first arc-shaped plate and the second arc-shaped plate, and a plurality of rubber strips are installed on the inner sides of the rubber blocks, the first arc-shaped plate and the second arc-shaped plate, and the friction force with the fiber bundle is increased through the rubber strips.

[0015] A winding and unwinding rod is installed at the end of the sensor, a connecting belt is installed on the outer side of the winding and unwinding rod, and one end of the connecting belt away from the winding and unwinding rod is fixedly connected to the ring, and the rotation of the winding and unwinding rod drives the connecting belt to contract and drives the ring to move.

[0017] A guide rod is installed inside the round rod, and the guide rod is movably connected to the movable block, and the movable block moves through the guidance of the guide rod.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, by setting the fixing component, the first arc-shaped plate and the second arc-shaped plate can rotate towards each other to lock the fiber bundle after the fixing belt is tightened. At the same time, the fiber bundle is extruded by the fixing belt, so that the fiber bundle is firmly clamped to ensure that there is no sliding of the fiber bundle during the pulling process.

[0020] 2. In the present invention, by sensing the change of the tension of the fiber bundle through the sensor, the response can be triggered instantly when the fiber bundle breaks, and the broken fiber bundle is pulled to the inside of the round rod by driving the ring through the servo motor, so as to avoid the entanglement of the fiber bundle break with other fiber bundles.

[0031] Embodiment 1

[0032] Such as Figure 1 - Figure 8As shown in the figure, a manufacturing device for a prestressed fiber braided net reinforced concrete slab proposed by the present invention includes a base 1. On the upper part of the base 1, movable plates 4 are symmetrically and slidably arranged. On the upper part of the base 1, cylinders 5 are symmetrically installed. The output end of the cylinder 5 is fixedly connected to the movable plate 4. On the upper part of the base 1, a plurality of round rods 8 are symmetrically and slidably arranged. A fixing component is arranged on the round rod 8. The fixing component includes a first arc plate 17 and a second arc plate 18 respectively rotatably connected to the end parts of the round rod 8, a fixing belt 9 installed at the end part of the round rod 8, a first threaded rod 10 rotatably connected to the inner side of the round rod 8, and a movable block 12 slidably arranged on the inner side of the round rod 8. A rotating plate 13 is installed at the end of the first threaded rod 10. The rotating plate 13 is movably connected to the movable plate 4. The movable block 12 is fixedly connected to the fixing belt 9. A ring 25 is movably connected to the end of the round rod 8. The fiber bundle passes through the ring 25 and is placed between the first arc plate 17 and the second arc plate 18. Rotating the first threaded rod 10 drives the movable block 12 to move. The movable block 12 moves to tighten the fixing belt 9 to squeeze the fiber bundle, and the fixing belt 9 drives the first arc plate 17 and the second arc plate 18 to rotate towards each other and clamp the fiber bundle, so that the fiber bundle is firmly clamped, ensuring that there is no sliding of the fiber bundle during the pulling process;

[0033] A servo motor 21 is installed on the inner side of the round rod 8. A sensor 22 is installed at the end of the servo motor 21. The sensor 22 is movably connected to the ring 25. After the fiber bundle is broken and the sensor 22 senses it, the servo motor 21 is started to drive the ring 25 to move to the inner side of the round rod 8, and at the same time drive the fiber bundle to contract, avoiding the fiber bundle from breaking and winding with other fiber bundles.

[0034] Sliding grooves 2 are symmetrically opened on both sides of the base 1. Sliding blocks 3 are slidably arranged on the inner sides of the sliding grooves 2. The sliding blocks 3 are fixedly connected to the movable plates 4. The movable plates 4 move along the sliding grooves 2 through the sliding blocks 3. A connecting plate 7 is installed on the side surface of the movable plate 4. The output end of the cylinder 5 is fixedly connected to the connecting plate 7. Telescopic rods 6 are symmetrically installed on both sides of the base 1. The telescopic rods 6 are fixedly connected to the movable plates 4. The movable plates 4 move under the guidance of the telescopic rods 6.

[0035] A second threaded rod 14 is rotatably connected to the side of the rotating plate 13 close to the movable plate 4. The second threaded rod 14 is threadedly connected to the movable plate 4. The acting force generated when the second threaded rod 14 rotates drives the round rod 8 to move.

[0036] A square plate 27 is installed on the upper part of the round rod 8. The square plate 27 and the round rod 8 are jointly slidably connected to the base 1. The round rod 8 slides under the guidance of the square plate 27.

[0037] A fixing belt 9 is installed inside the round rod 8. The fixing belt 9 is slidably connected to the movable block 12. When the movable block 12 moves, it drives the fixing belt 9 to move and tighten it.

[0038] A support plate 15 is installed at the end of the round rod 8. A rotating rod 16 is installed on the outer side of the support plate 15. Both the first arc plate 17 and the second arc plate 18 are rotatably connected to the rotating rod 16. A torsion spring 19 is jointly installed between the first arc plate 17 and the second arc plate 18. The first arc plate 17 and the second arc plate 18 rotate towards each other to clamp the fiber bundle.

[0039] Rubber blocks 20 are installed on one side of the fixing belt 9 close to the first arc plate 17 and the second arc plate 18. A plurality of rubber strips 28 are installed on the inner sides of the rubber blocks 20, the first arc plate 17 and the second arc plate 18. The friction force with the fiber bundle is increased through the rubber strips 28.

[0040] A guide rod 11 is installed inside the round rod 8. The guide rod 11 is movably connected to the movable block 12. The movable block 12 moves through the guidance of the guide rod 11.

[0041] In this embodiment, during manufacturing, first, the fiber bundle is passed through the ring 25 and placed between the first arc plate 17 and the second arc plate 18. Then, the rotating plate 13 is rotated. The first threaded rod 10 is driven to rotate through the rotating plate 13. When the first threaded rod 10 rotates, the acting force generated drives the movable block 12 to move along the round rod 8 through the guide rod 11, and at the same time drives the fixing belt 9 to move, so that the fixing belt 9 is tightened. The fixing belt 9 can then squeeze the fiber bundle and the first arc plate 17 and the second arc plate 18. By squeezing the arc surfaces of the first arc plate 17 and the second arc plate 18, the first arc plate 17 and the second arc plate 18 can be driven to rotate towards each other along the rotating rod 16. At this time, the torsion spring 19 contracts, and the first arc plate 17 and the second arc plate 18 can clamp the fiber bundle. At the same time, the fixing belt 9 squeezes the fiber bundle through the rubber block 20, and the friction force between the fixing belt 9, the first arc plate 17, the second arc plate 18 and the fiber bundle can be increased through the rubber strips 28, so as to stably fix the fiber bundle and prevent it from falling off during tensioning, which affects the manufacturing work. Then, the second threaded rod 14 is rotated. When the second threaded rod 14 rotates, the acting force generated drives the round rod 8 to move, and at the same time drives the fiber bundle to be tensioned to ensure that the prestresses of multiple fiber bundles are consistent. After that, the air cylinder 5 is started. The air cylinder 5 drives the movable plate 4 to move, so that the movable plate 4 moves through the guidance of the telescopic rod 6, and the movable plate 4 moves along the sliding groove 2 through the sliding block 3, and then drives the fiber bundles on all the round rods 8 to move for tensioning work.

[0042] Embodiment Two

[0043] Such as Figure 1 -Figure 8 As shown, based on the first embodiment, a retractable rod 23 is installed at the end of the sensor 22. A connecting belt 24 is installed on the outer side of the retractable rod 23. One end of the connecting belt 24 away from the retractable rod 23 is fixedly connected to a circular ring 25. The rotation of the retractable rod 23 drives the contraction of the connecting belt 24 and drives the movement of the circular ring 25.

[0044] An opening groove 26 is provided at the end of the round rod 8. The circular ring 25 moves through the opening groove 26 to the inside of the round rod 8.

[0045] In this embodiment, when the fiber bundle breaks during the tensioning process, at this time, the sensor 22 can sense the change in the acting force, then start the servo motor 21, drive the retractable rod 23 to rotate through the servo motor 21, thereby driving the contraction of the connecting belt 24, and then driving the circular ring 25 to move through the opening groove 26 to the inside of the round rod 8. When the circular ring 25 moves, it can pull the fiber bundle to the inside of the round rod 8 to prevent the broken fiber bundle from entangling with other fiber bundles.

[0046] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
