Technical Field

[0001] This utility model relates to the technical field of bridge protection, and in particular to a high-efficiency winding tool for continuous main reinforcement bars on bridge decks. Background Technology

[0002] In traditional bridge construction, the continuous main reinforcement of the bridge deck needs to be waterproofed and protected to ensure the durability and safety of the bridge. This usually involves wrapping the main reinforcement with multiple layers of protective materials, such as fiberglass cloth and polyethylene tape. However, there are no readily available materials on the market that can be directly applied to this wrapping work. Therefore, it is necessary to wrap and wrap by hand. This manual operation is not only inefficient but also labor-intensive, requiring the labor of multiple workers. Utility Model Content

[0006] By adopting the above technical solution, when wrapping the protective layer, one end of the protective material is pasted and fixed on the rotating shaft. Then, one worker is responsible for turning the handle, which drives the rotating shaft to rotate, and the rotating shaft drives the protective material to rotate. At the same time, another worker provides assistance to ensure the smooth progress of the wrapping process, thereby improving the wrapping efficiency of the protective material and reducing construction costs.

[0007] Optionally, a moving mechanism is installed on the bracket, the moving mechanism includes a moving plate, the ends of the two brackets away from the bearing are fixedly connected to the moving plate, and four moving wheels are rotatably connected to the end of the moving plate away from the bearing; a support assembly is also installed on the moving plate.

[0008] By adopting the above technical solution, the movable plate and movable wheels enable the support to move, thereby facilitating the movement of the entire device. At the same time, when it moves to the designated position, the support mechanism supports the movable plate, reducing the probability of the movable plate accidentally sliding.

[0009] Optionally, a first sliding groove is formed on the end face of the movable plate away from the bracket. The support assembly includes a support leg and a power component. The support leg is slidably connected in the first sliding groove, and the power component is mounted on the movable plate and connected to the support leg.

[0010] By adopting the above technical solution, when the entire device is moved to the designated position, the power component is adjusted, and the power component drives the support leg to slide out of the first slide groove until the support leg contacts the ground. At this time, the support leg supports the moving plate, thereby reducing the probability of the moving plate accidentally sliding.

[0011] Optionally, the power component includes two first mounting plates, both of which are fixedly connected to the end face of the movable plate away from the movable wheel. A drive rod is rotatably connected to both first mounting plates, and a first bevel gear is fixedly connected to the drive rod. A rotating groove is formed on the end face of the movable plate near the rotating shaft, and the rotating groove communicates with the first sliding groove. A limit groove is formed on the side wall of the rotating groove. A first lead screw is rotatably connected in the rotating groove. The first lead screw is threadedly connected to the support leg. A limit ring is fixedly connected to the side wall of the first lead screw, and the limit ring is rotatably connected in the limit groove. A second bevel gear is fixedly connected to the end of the first lead screw away from the support leg, and the second bevel gear meshes with the first bevel gear.

[0012] By adopting the above technical solution, when the support leg slides, the drive rod is manually rotated, the drive rod drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, the second bevel gear drives the first lead screw to rotate, and the first lead screw drives the support leg to slide out of the first slide groove to support the moving plate.

[0013] Optionally, an auxiliary mechanism is installed on the movable plate. The auxiliary mechanism includes a support block, which is fixedly connected to the end face of the movable plate near the rotating shaft. A second mounting plate is fixedly connected to the end of the support block away from the movable plate. A through groove is provided on the end face of the second mounting plate near the rotating shaft. Rollers are rotatably connected to the side walls at both ends of the groove. A clamping assembly is also installed in the groove.

[0014] By adopting the above technical solution, when the protective material is wound, the protective material output from the rotating shaft passes through the groove, and the roller in the groove supports the protective material, thereby reducing the probability of the protective material being scratched when it is wound. At the same time, the clamping component realizes the stable output of the protective material, thereby further improving the winding efficiency of the protective material.

[0015] Optionally, a plurality of second sliding grooves are provided on the side wall of the groove away from the movable plate. The clamping assembly includes a plurality of springs, which are respectively fixedly connected to the bottom wall of the plurality of second sliding grooves.

The driving assembly includes a second lead screw, which is rotatably connected to the second mounting plate. A slider is slidably connected in the third sliding groove. The slider is threadedly connected to the second lead screw. A connecting rod is fixedly connected to the slider and is fixedly connected to the cutting blade.

[0020] By adopting the above technical solution, when cutting the protective material, the second lead screw is manually rotated, the second lead screw drives the slider to slide, the slider drives the connecting rod to move, and the connecting rod drives the cutting blade to cut the protective material.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. When wrapping the protective layer, one end of the protective material is attached and fixed to the rotating shaft. Then, one worker is responsible for turning the handle, which drives the rotating shaft to rotate, and the rotating shaft drives the protective material to rotate. At the same time, another worker provides assistance to ensure the smooth progress of the wrapping process, thereby improving the wrapping efficiency of the protective material and reducing construction costs.

[0023] 2. Manual wrapping suffers from uneven wrapping and inconsistent tightness. However, using tools ensures the uniformity and tightness of the wrapping material due to the more standardized and mechanized wrapping process, thereby improving the wrapping quality, enhancing the waterproofing and protection of the bridge, and ultimately increasing the bridge's service life.

[0024] 3. The movable plate and casters enable the support to move, which in turn facilitates the movement of the entire device. At the same time, when it is moved to the designated position, the support legs support the movable plate, reducing the probability of the movable plate accidentally sliding.

[0025] 4. When the protective material is output, it is located between the rolling wheel and the idler roller. At this time, the spring drives the sliding shaft to move, the sliding shaft drives the U-shaped mounting block to move, and the U-shaped mounting block drives the rolling wheel to press the protective material onto the idler roller, thereby making the output of the protective material more stable.

Detailed Implementation

[0035] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0036] This application discloses a high-efficiency winding tool for continuous main reinforcement bars on bridge decks.

[0037] Example 1:

[0038] refer to Figure 1 The bridge deck continuous main reinforcement crank handle high-efficiency winding tool includes two supports 1, both supports 1 are placed on the ground, and the ends of the two supports 1 away from the ground are fixedly connected to bearings 2. The two bearings 2 are rotatably connected to a rotating shaft 3, and one end of the rotating shaft 3 is fixedly connected to a handle 4.

[0039] The implementation principle of Embodiment 1 of this application is as follows: one end of the protective material is pasted and fixed on the rotating shaft 3. Then, a worker is responsible for cranking the handle 4. The handle 4 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the protective material to rotate. At the same time, another worker provides assistance to ensure the smooth progress of the winding process, thereby improving the winding efficiency of the protective material and reducing the construction cost.

[0040] Example 2:

[0041] refer to Figure 2 The difference between this embodiment and embodiment 1 is that a moving mechanism 5 is also installed on the bracket 1. The moving mechanism 5 includes a moving plate 51, which is fixedly connected to the end of the two brackets 1 away from the rotating shaft 3. Four moving wheels 52 are rotatably connected to the end face of the moving plate 51 away from the rotating shaft 3. The four moving wheels 52 are located at the four corners of the moving plate 51 respectively. The setting of the moving plate 51 and the moving wheels 52 realizes the movement of the bracket 1, thereby facilitating the movement of the entire device.

[0042] refer to Figure 3 and Figure 4 The moving plate 51 has a first sliding groove 511 on its end face away from the rotating shaft 3, and a rotating groove communicating with the first sliding groove 511 on its end face near the rotating shaft 3. A limit groove 512 is formed on the side wall of the rotating groove. The moving mechanism 5 also includes a support assembly 53, which includes support legs 531 slidably connected in the first sliding groove 511. The support assembly 53 also includes a power component 54, which includes two first mounting plates 541. A drive rod 542 is rotatably connected to 41. One end of the drive rod 542 is fixedly connected to a first bevel gear 544. A first lead screw 545 is rotatably connected in the rotating groove. The first lead screw 545 is threadedly connected to the support leg 531. A limit ring 543 is fixedly connected to the side wall of the first lead screw 545. The limit ring 543 is rotatably connected in the limit groove 512. A second bevel gear 546 is fixedly connected to the end of the first lead screw 545 near the rotating shaft 3. The second bevel gear 546 meshes with the first bevel gear 544.

[0043] Once the entire device has been moved to the designated position, the drive rod 542 is manually rotated. The drive rod 542 drives the first bevel gear 544 to rotate, the first bevel gear 544 drives the second bevel gear 546 to rotate, the second bevel gear 546 drives the first lead screw 545 to rotate, and the first lead screw 545 drives the support leg 531 to slide out of the first slide groove 511 to support the moving plate 51, thereby reducing the probability of the moving plate 51 sliding accidentally.

[0044] refer to Figure 5 An auxiliary mechanism 6 is also installed on the movable plate 51. The auxiliary mechanism 6 includes two support blocks 61. Both support blocks 61 are fixedly connected to the end face of the movable plate 51 near the rotating shaft 3. The ends of the two support blocks 61 away from the movable plate 51 are fixedly connected to a second mounting plate 62. A through groove 621 is opened on the side wall of the second mounting plate 62 near the rotating shaft 3. Rollers 63 are rotatably connected to the side walls at both ends of the groove 621. A clamping assembly 64 is installed on the side wall of the groove 621 away from the movable plate 51.

[0045] When the protective material is being wound, the protective material output from the rotating shaft 3 passes through the groove 621. The roller 63 in the groove 621 supports the protective material, thereby reducing the probability of the protective material being scratched during the winding process. At the same time, the clamping assembly 64 achieves stable output of the protective material, thereby further improving the winding efficiency of the protective material.

[0046] refer to Figure 6The groove 621 has multiple second sliding grooves 622 on its side wall away from the moving plate 51. The clamping assembly 64 includes multiple springs 641, which are fixedly connected to the bottom wall of the multiple second sliding grooves 622. Each of the multiple springs 641 has a sliding shaft 642 fixedly connected to one end near the moving plate 51. The multiple sliding shafts 642 are slidably connected in the multiple second sliding grooves 622. Each of the multiple sliding shafts 642 has a U-shaped mounting block 643 fixedly connected to one end near the moving plate 51. A rolling wheel 644 is rotatably connected in the U-shaped groove of the U-shaped mounting block 643.

[0047] When the protective material is output, it is located between the rolling wheel 644 and the idler roller 63. At this time, the spring 641 drives the sliding shaft 642 to move, the sliding shaft 642 drives the U-shaped mounting block 643 to move, and the U-shaped mounting block 643 drives the rolling wheel 644 to press the protective material onto the idler roller 63, thereby making the output of the protective material more stable.

[0048] refer to Figure 7 and Figure 8 A third groove 623 is provided along the length direction on the end face of the second mounting plate 62 away from the moving plate 51. A cutting mechanism 7 is mounted on the second mounting plate 62. The cutting mechanism 7 includes a drive assembly 72, which includes a second lead screw 721. The second lead screw 721 is rotatably connected in the third groove 623. A slider 722 is also slidably connected in the third groove 623. The slider 722 is threadedly connected to the second lead screw 721. A connecting rod 723 is fixedly connected to the side wall of the slider 722 away from the rotating shaft 3. A cutting blade 71 is fixedly connected to the end face of the connecting plate near the moving plate 51.

[0049] When cutting the protective material, manually rotate the second lead screw 721. The second lead screw 721 drives the slider 722 to slide, the slider 722 drives the connecting rod 723 to slide, and the connecting rod 723 drives the cutting blade 71 to cut the protective material.

[0050] The implementation principle of Embodiment 2 of this application is as follows: When the protective material for the main reinforcement of the bridge deck is being wound, the protective material output from the rotating shaft 3 is first passed through the groove 621. At this time, the rolling wheel 644 and the idler roller 63 cooperate to clamp the protective material, thereby achieving stable output of the protective material. After the protective material is wound, the second lead screw 721 is manually rotated. The second lead screw 721 drives the slider 722 to slide, the slider 722 drives the connecting rod 723 to slide, and the connecting rod 723 drives the cutting blade 71 to cut the protective material. This facilitates the winding of the protective material for the main reinforcement of the bridge deck and improves the winding efficiency.

[0051] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
