Description

Technical Field

[0001] This utility model is a crack-resistant base fabric laying device, belonging to the field of crack-resistant base fabric. Background Technology

[0002] my country is a powerhouse in infrastructure construction, with numerous roads under construction across the country every year. Facing challenges such as high altitudes, large temperature differences, constant freeze-thaw cycles, and uneven settlement of the roadbed, asphalt pavements are prone to cracking, leading to water infiltration and further damage. Therefore, adding anti-crack base fabric to reconstructed and newly built roads can effectively reduce and delay the formation of reflective cracks in semi-rigid base layers, preventing water infiltration. Polypropylene anti-crack base fabric is made from 100% virgin polypropylene filaments in a non-woven fabric, manufactured using a patented mechanical needle-punching process. It is a specially developed waterproof and crack-resistant pavement material for new or reconstructed road surfaces, designed to prevent reflective cracking. Its main functions include: seepage prevention, sealing, waterproofing, stress absorption, crack prevention, good adhesion between layers, low-strain stiffness of the base fabric, and coordinated deformation with asphalt, providing reinforcement. Polypropylene filament anti-crack base fabric is made from polypropylene filaments using a special processing technique.

[0003] When laying existing polypropylene filament anti-crack base fabric, the construction environment may cause foreign objects to adhere to the surface of the anti-crack base fabric, affecting the adhesion effect of the base fabric construction surface or the flatness of the base fabric laying. Therefore, this utility model proposes a cleanable anti-crack base fabric laying device. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a crack-resistant base fabric laying device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A crack-resistant base fabric laying device includes a housing, a take-up roller rotatably connected inside the housing, a crack-resistant base fabric wound on the take-up roller, one end of the crack-resistant base fabric being wound around and fixed to the surface of the take-up roller, a clamping assembly corresponding to the take-up roller being provided at the top of the housing, a plurality of insertion holes being provided at the other end of the take-up roller, a pin being inserted into the insertion holes, a cleaning assembly being installed on the inner side of the housing, a drive assembly for driving the take-up roller being provided on the housing, and the cleaning assembly including a cleaning plate having cleaning bristles on the end face of the cleaning plate facing the crack-resistant base fabric.

[0007] Furthermore, the clamping assembly includes a U-shaped frame fixed to the top of the housing with screws, and multiple reset components fixed to the bottom of the U-shaped frame with screws. The reset components include upper and lower mounting plates, and multiple springs are fixed between the mounting plates.

[0008] Furthermore, a clamping component is provided below the reset component. The clamping component includes multiple clamping rods, which are rotatably connected by a bearing. A fixing plate is fixed at the bottom of the reset component, and the fixing plate is fixed to the outer wall of the outer ring of the bearing with screws.

[0009] Furthermore, the drive assembly includes a drive box fixed to the outer wall of the housing, a drive motor is installed inside the drive box, a meshing wheel is connected to the output end of the drive motor, and a secondary meshing wheel is meshed on one side of the meshing wheel.

[0010] Furthermore, the auxiliary meshing wheel is rotatably mounted in the drive box via a bearing, and a rotating rod for connecting the take-up roller is provided through the central shaft of the auxiliary meshing wheel.

[0011] Furthermore, a steering roller is rotatably installed inside the housing. Both ends of the winding roller and the steering roller are rotatably connected by bearing three, and the bearing three is embedded in the housing.

[0012] Furthermore, a mounting plate corresponding to the cleaning plate is fixedly installed on the inner wall of the box. Mounting pieces are fixed at both ends of the cleaning plate, and the mounting pieces are fixed to the mounting plate with screws. Connectors are provided on the outer wall of the box.

[0013] Furthermore, a corresponding plate is fixedly installed on the inner side wall of the box, and threaded holes are opened on the corresponding plate. Box doors are fixedly installed on both sides of the outer side wall of the box, and handles are provided on the box doors.

[0014] The beneficial effects of this utility model are:

[0015] The drive assembly can drive the take-up roller to rotate forward and backward, which can take up and unwind the base fabric, improve the efficiency of base fabric recycling and reuse, increase work efficiency, and speed up the project progress.

[0016] The pressing component presses down the base fabric to prevent the base fabric from scattering due to the rotation of the winding roller, which would affect the flatness of the base fabric. At the same time, it can also maintain the flatness of the base fabric during recycling, making it easier to lay and use next time.

[0017] By cleaning the surface of the crack-resistant base fabric with a cleaning brush, it is possible that foreign objects may adhere to the surface of the existing polypropylene filament crack-resistant base fabric during the construction environment. This is to prevent foreign objects from adhering to the surface of the crack-resistant base fabric during the next recycling, which may affect the adhesion of the base fabric to the construction surface or the flatness of the base fabric. Therefore, a cleaning brush is set up to contact the surface of the crack-resistant base fabric to sweep away dust or foreign objects on the surface of the crack-resistant base fabric, improve the adhesion between the crack-resistant base fabric and the construction surface, and improve the flatness of the crack-resistant base fabric during the laying.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a crack-resistant base fabric laying device, including a box body 1, a take-up roller 2 rotatably connected inside the box body 1, a crack-resistant base fabric 3 wound on the take-up roller 2, one end of the crack-resistant base fabric 3 being wound around and fixed to the surface of the take-up roller 2, a pressing component corresponding to the take-up roller 2 being provided at the top of the box body 1, a plurality of insertion holes 4 being provided at the other end of the take-up roller 2, and a pin 5 being inserted into the insertion holes 4, a cleaning component being installed on the inner side of the box body 1, a driving component for driving the take-up roller 2 being provided on the box body 1, and the cleaning component including a cleaning plate 6, with cleaning bristles 7 on the end face of the cleaning plate 6 facing the crack-resistant base fabric 3.

[0026] See Figure 3 The clamping assembly includes a U-shaped frame 8 fixed to the top of the housing 1 with screws. Multiple reset components are fixed to the bottom of the U-shaped frame 8 with screws. The reset components include upper and lower mounting plates 9. Multiple springs 10 are fixed between the mounting plates 9. A clamping component is provided below the reset component. The clamping component includes multiple clamping rods 11. The clamping rods 11 are rotatably connected by a bearing 12. A fixing plate 13 is fixed to the bottom of the reset component. The fixing plate 13 is fixed to the outer wall of the outer ring of the bearing 12 with screws. The clamping rod 11 is a rotating connection. A connecting rod is provided on the inner ring of the bearing 12, which connects to the adjacent clamping rod 11, ensuring that the clamping rod 11 is a movable connection. This greatly reduces the friction between the clamping rod 11 and the base fabric, improving the quality of the base fabric. The clamping rod 11 works in conjunction with a spring to press down on the base fabric, preventing the base fabric from scattering due to the rotation of the take-up roller 2, which would affect the flatness of the base fabric. It also helps to maintain the flatness of the base fabric during recycling, facilitating its next use. Multiple vertically arranged telescopic rods are also fixed between the upper and lower mounting horizontal plates 9, as can be seen directly in the figure.

[0027] See Figure 4 The drive assembly includes a drive box 14 fixed to the outer wall of the housing 1. A drive motor 15 is housed within the drive box 14. The output rod of the drive motor 15 is connected to a meshing wheel 16. A secondary meshing wheel 17 meshes with one side of the meshing wheel 16. The secondary meshing wheel 17 is rotatably mounted within the drive box 14 via a bearing. A rotating rod 18, connecting to the take-up roller 2, is threaded through the central shaft of the secondary meshing wheel 17. The drive motor 15 drives the meshing wheel 16 to rotate, which in turn drives the secondary meshing wheel 17 to rotate. Combined with the rotating rod 18, this allows the take-up roller 2 to rotate forward and backward, enabling the winding and unwinding of the base fabric. This improves the efficiency of base fabric recycling and reuse, increases work efficiency, and accelerates project progress. The drive motor 15 is a forward / reverse type motor, a readily available device.

[0028] See Figure 1 Inside the housing 1, a steering roller 19 is rotatably installed. The winding roller 2 and the steering roller 19 are rotatably connected at both ends by bearing 3 20, and the bearing 3 20 is embedded in the housing 1. Multiple steering rollers 19 are provided. The base fabric can be wound around the top and bottom of the steering roller 19 so that the steering roller 19 can stably guide the base fabric.

[0029] See Figure 1-2The inner wall of the housing 1 is fixed with a mounting plate 21 corresponding to the cleaning plate 6. Both ends of the cleaning plate 6 are fixed with mounting pieces 22. The mounting pieces 22 are fixed to the mounting plate 21 with screws. The outer wall of the housing 1 is provided with a connector. The inner side wall of the housing 1 is fixed with a corresponding plate 23. The corresponding plate 23 has a threaded hole 25. Both sides of the outer wall of the housing 1 are fixed with a door 24. The door 24 is provided with a handle. The cleaning components can be installed by opening the door 24. The door 24 has a lock installed on the housing. The external engineering vehicle is connected to the housing through the connector. The pin is inserted into the ground through the insertion hole 4 to fix one end of the base cloth. After the cloth is taken back, the insertion hole 4 corresponds to the threaded hole 25. In addition, a tightening screw is provided through the insertion hole 4. The tightening screw is screwed into the threaded hole 25 to fix one end of the base cloth to the corresponding plate 23.

[0030] During use, the drive assembly can rotate the take-up roller 2 forward and reverse, allowing for the unwinding and rewinding of the base fabric. This improves the efficiency of base fabric recycling and reuse, increases work efficiency, and accelerates project progress. The pressing assembly presses down on the base fabric to prevent the take-up roller 2 from causing it to scatter and affecting the flatness of the base fabric. It also maintains the flatness of the base fabric during recycling, facilitating future use. The cleaning brush 7 cleans the surface of the crack-resistant base fabric 3. During the existing installation of polypropylene filament crack-resistant base fabric, the construction environment may cause foreign objects to adhere to the surface. To prevent foreign objects from adhering to the surface during subsequent recycling, which could affect the adhesion of the base fabric or the flatness of the paving, the cleaning brush 7 is installed to contact the surface of the crack-resistant base fabric 3, sweeping away dust or foreign objects, improving the adhesion between the crack-resistant base fabric and the construction surface, and enhancing the flatness of the crack-resistant base fabric during paving.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
