Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, specifically to a concrete curing covering device for construction projects. Background Technology

[0002] After concrete is poured and formed, its strength gain and durability improvement depend on the hydration reaction of cement, which requires a suitable temperature and humidity environment. If the moisture on the concrete surface evaporates too quickly, the cement hydration reaction will be incomplete, leading to problems such as surface cracking, sandblasting, and insufficient strength, seriously affecting the stability and service life of the building structure. Therefore, concrete curing is a critical step in construction projects. Its core purpose is to create stable conditions for the concrete hydration reaction through moisture retention and heat preservation measures, ensuring that it meets the design strength and durability requirements.

[0003] Based on the above, the inventors have discovered the following problems: Current concrete curing methods mostly use plastic film to retain moisture. This method requires first unrolling the plastic film using a roller, and then manually stretching it to cover the concrete surface. When the film reaches the specified length, operators need to use additional tools such as scissors and utility knives to cut it. This is not only cumbersome and inefficient, but manual cutting is also prone to uneven cuts, tears, and rough edges, affecting subsequent covering. At the same time, the cutting process requires a dedicated person to fix the film and a dedicated person to operate the tools, which wastes manpower.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a concrete curing covering device for construction projects, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide a concrete curing and covering device for construction projects to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows: A concrete curing covering device for construction projects includes a covering component and a cutting component. The covering component includes a handle, with supports welded to both sides of the bottom surface of the handle. Each pair of supports has a through hole at the end away from the handle, and a round rod is rotatably connected inside each of the two through holes. A connecting plate is welded to the opposite end of each of the two round rods, and a roller is disposed between the two connecting plates. A thin film is wrapped around the outer wall of the roller. The cutting component includes a linear motor, with a pair of support rods installed on one side of the outer wall of the linear motor. A cutting seat is installed at the end of the pair of support rods away from the linear motor, and a cutting groove is provided on the top surface of the cutting seat. A rotary cutter is disposed directly above the cutting groove.

[0007] Furthermore, a slide block is installed at the output end of the linear motor, an electric slide rail is installed on the top surface of the slide block, an electric slider is slidably connected to the outside of the electric slide rail, a heat sink is installed on the outer side wall of the electric slider, a micro servo motor is installed on the inner side wall of the heat sink, and the output end of the micro servo motor is fixedly connected to the rotary cutter.

[0008] The beneficial effects of adopting the above-mentioned further solution are that the electric slide rail drives the electric slider to move downward, which can accurately control the bonding depth between the rotary cutter and the film and the cutting groove. This ensures that the rotary cutter can partially bond with the film and enter the cutting groove during cutting, avoiding incomplete cutting, and also prevents excessive pressure from damaging the film or the cutting seat. The micro servo motor provides stable rotational power for the rotary cutter, which, together with the linear motor driving the slide, drives the cutting structure to move linearly, realizing the coordinated action of rotary cutting and linear feeding, making the film cutting cut smooth and avoiding problems such as tearing and rough edges.

[0009] Furthermore, mounting grooves are provided on both sides of the outer wall of the heat sink, and a waterproof and breathable membrane is installed inside each mounting groove. A stainless steel filter screen is installed inside the mounting groove on the side of the waterproof and breathable membrane.

[0010] The beneficial effects of adopting the above-mentioned further solution are that the microporous structure of the waterproof and breathable membrane can both allow hot air inside the heat sink to be discharged to the outside, achieving effective heat dissipation, and prevent external rainwater, maintenance water and other liquids from entering the heat sink, thus avoiding short circuits caused by moisture in the micro servo motor; the stainless steel filter can filter impurities in the air, and the stainless steel filter and the waterproof and breathable membrane are installed from the outside of the heat sink to the inside of the heat sink.

[0011] Furthermore, limiting discs are fitted on the outside of both ends of the roller body, the film is located between a pair of limiting discs, and one end of the film can be placed on the top surface of the cutting seat.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the limiting plate can play a lateral limiting role on the film on the roller; one end of the film is placed on the top surface of the cutting seat and always adheres to the top surface of the cutting seat when stretched, providing a stable reference for subsequent cutting.

[0013] Furthermore, positioning grooves are provided on the outer walls of both ends of the roller body, and positioning blocks are provided inside the two positioning grooves. The outer walls of the positioning blocks are slidably engaged with the inner walls of the positioning grooves, and the two positioning blocks are fixedly connected to the two connecting discs on the side away from the roller body, respectively, on the side away from the round rod.

[0014] The beneficial effects of adopting the above-mentioned further solution are that the sliding fit between the positioning groove and the positioning block provides precise positioning for the installation of the roller body and the connecting plate, ensuring that the roller body can be coaxial with the round rod after installation, and avoiding uneven film stretching during rotation due to installation misalignment; at the same time, the sliding fit between the positioning groove and the positioning block facilitates the quick assembly and disassembly of the roller body, and when the film on the roller body is used up, the old roller body can be easily disassembled and a new roller body can be replaced.

[0015] Furthermore, the roller body has a first screw hole on the outer wall at both ends of the positioning groove, and the connecting disc has a second screw hole on the inside of both sides of the positioning block. The first screw hole and the second screw hole are threadedly connected by bolts, and a transmission seat is installed on the end of the bolt away from the roller body.

[0016] The beneficial effects of adopting the above-mentioned further solution are that the threaded connection between the bolt and the first and second screw holes can firmly fix the roller body and the connecting plate, prevent the roller body and the connecting plate from becoming relatively loose during the pulling process of the device, and ensure the stable rotation of the roller body; at the same time, when the film on the roller body is used up, the old roller body can be easily disassembled and replaced with a new roller body by unscrewing the bolt; the setting of the transmission seat provides a convenient force point for the rotation operation of the bolt.

[0017] Furthermore, the outer surface of the transmission seat is provided with several grooves.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the groove can increase the friction between the operator's hand and the transmission seat, and prevent slippage when rotating the transmission seat. Especially when the hands may be covered with dust and moisture at the concrete curing site, it can still ensure stable force application.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: The concrete curing covering device for construction projects provides users with a convenient gripping point on the handle, and the force can be stably applied through the handle when pulling the device, which is suitable for the mobile operation needs of the concrete curing site; the rotational cooperation between the bracket and the round rod allows the roller to rotate flexibly as the device is pulled, ensuring that the film can be smoothly stretched and unfolded from the roller; the film wrapped around the roller serves as the main body of the concrete curing covering, which can effectively isolate external impurities, reduce the rapid evaporation of concrete moisture, and ensure the curing effect; the cutting seat cooperates with the rotary cutter to quickly cut the film after it has been covered to the specified length.

[0023] Please see Figures 1-5This utility model provides a technical solution: a concrete curing covering device for construction projects, including a covering component 1 and a cutting component 2. The covering component 1 includes a handle 11, with supports 12 welded to both sides of the bottom surface of the handle 11. Each pair of supports 12 has a through hole 13 at the end furthest from the handle 11. A round rod 14 is rotatably connected inside each of the two through holes 13. A connecting plate 15 is welded to the opposite end of each of the two round rods 14.

A pair of support rods 22 are mounted on one side of the outer wall of the linear motor 21. A cutting seat 23 is mounted on the end of the pair of support rods 22 away from the linear motor 21. A cutting groove 24 is provided on the top surface of the cutting seat 23. A rotary cutter 28 is provided directly above the cutting groove 24. A slide is mounted on the output end of the linear motor 21. An electric slide rail 25 is mounted on the top surface of the slide. An electric slider is slidably connected to the outside of the electric slide rail 25. A heat sink 26 is mounted on the outer wall of the electric slider. A micro servo motor 27 is mounted on the inner wall of the heat sink 26. The output end of the micro servo motor 27 is connected to the rotary cutter 28. The device is fixedly connected; the handle 11 provides a convenient grip point for the user, allowing for stable force application when pulling the device, adapting to the mobile operation needs of concrete curing sites; the rotational cooperation between the bracket 12 and the round rod 14 allows the roller 16 to rotate flexibly as the device is pulled, ensuring that the film 18 can be smoothly stretched and unfolded from the roller 16; the film 18 wrapped around the roller 16 serves as the main body of concrete curing coverage, effectively isolating external impurities, reducing the rapid evaporation of concrete moisture, and ensuring curing effect; the cutting seat 23 cooperates with the rotary cutter 28 to quickly cut the film 18 after it has covered to a specified length.

[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 Figures 1-5This utility model provides a technical solution: The outer walls of the heat dissipation box 26 are provided with mounting grooves on both sides. A waterproof and breathable membrane 29 is installed inside each mounting groove. A stainless steel filter screen is installed on one side of the waterproof and breathable membrane 29 inside the mounting groove. Limiting discs 17 are fitted onto the outer sides of both ends of the roller body 16. A film 18 is located between a pair of limiting discs 17. One end of the film 18 can be placed on the top surface of the cutting seat 23. Positioning grooves 19 are provided on the outer walls of both ends of the roller body 16. Positioning blocks 110 are installed inside each of the two positioning grooves 19. The outer wall of the positioning block 110 slides into the inner wall of the positioning groove 19. The two positioning blocks 110 are fixedly connected to the two connecting discs 15 on the side away from the roller body 16, respectively, on the side away from the round rod 14. The roller body 16 has first screw holes on the outer walls at both ends of the positioning groove 19. The connecting discs 15 have second screw holes on the interior of both sides of the positioning blocks 110. Bolts 111 are threaded between the opposing first and second screw holes. A transmission seat 112 is installed at the end of the bolt 111 away from the roller body 16. The outer surface of roller 16 has several grooves. The positioning grooves 19 at both ends of the roller 16, on which the curing film 18 is wound, are aligned with the positioning blocks 110 on the connecting plate 15. The roller 16 is then slid in along the positioning blocks 110 to initially align with the connecting plate 15. Subsequently, the bolts 111 are rotated via the transmission seat 112, screwing them into the first screw hole of the roller 16 and the second screw hole of the connecting plate 15, thus firmly fixing the roller 16 to the connecting plate 15. At this time, the limiting discs 17 at both ends of the roller 16 can provide lateral limiting for the film 18, preventing the film from being damaged. The film 18 is offset; then the free end of the film 18 is pulled out and placed on the top surface of the cutting seat 23 to ensure that the film 18 is in close contact with the top surface of the cutting seat 23, providing a reference for subsequent stretching and cutting; if the film 18 on the roller body 16 is used up, the bolt 111 can be rotated in the opposite direction through the transmission seat 112 to unscrew the bolt 111 from the first screw hole and the second screw hole, and then the old roller body 16 can be removed by sliding along the positioning block 110. After replacing the roller body 16 with the new film 18, the above installation steps are repeated to continue the maintenance and covering operation.

[0026] Specifically, the working principle of this type of concrete curing covering device for construction projects is as follows: During use, the positioning grooves 19 at both ends of the roller body 16, which is wrapped with a curing film 18, are aligned with the positioning blocks 110 on the connecting plate 15. The roller body 16 is then slid in along the positioning blocks 110, initially aligning with the connecting plate 15. Subsequently, the bolts 111 are rotated via the transmission seat 112, screwing them into the first screw hole of the roller body 16 and the second screw hole of the connecting plate 15, thus firmly fixing the roller body 16 to the connecting plate 15. At this point, the two ends of the roller body 16... The limiting plate 17 at the end can limit the film 18 laterally to prevent the film 18 from shifting; then the free end of the film 18 is pulled out and placed on the top surface of the cutting seat 23 to ensure that the film 18 is in close contact with the top surface of the cutting seat 23, providing a reference for subsequent stretching and cutting; when covering concrete for curing, the operator holds the handle 11 with both hands and places the device at the starting position on the surface of the concrete to be cured, using the adhesiveness of the concrete when it is not completely solidified to make the free end of the film 18 adhere and fix to the concrete surface. The operator then pulls the handle 11 at a constant speed along the length of the concrete curing area. Under the pulling force, the round rod 14 in the through hole 13 of the bracket 12 rotates flexibly with the movement of the device, driving the connecting plate 15 and the roller 16 to rotate synchronously. The film 18 on the roller 16 is continuously stretched and unfolded, and under the action of concrete adhesion, it tightly covers the concrete surface, achieving curing coverage. During this process, the film 18 always slides along the top surface of the cutting seat 23, maintaining a close fit with the cutting seat 23 to ensure the stability of the covering path. When the film 18 covers to the specified length and needs to be cut, the pulling device is stopped, and the electric slide rail 25 is activated. The electric slide rail 25 drives the electric slider to move the heat sink 26 and the micro servo motor 27 synchronously downwards until the rotary cutter 28 fixed at the output end of the micro servo motor 27 partially contacts the surface of the film 18, and the cutter edge enters the cutting groove 24 of the cutting seat 23. This avoids excessive cutting pressure that could damage the film 18 or the cutting seat 23, while ensuring effective contact with the film 18. Then, the device is started synchronously. Miniature servo motor 27 and linear motor 21: Miniature servo motor 27 drives the rotary cutter 28 to rotate at high speed, generating cutting power; linear motor 21 drives the slide at the output end to move at a constant speed in the horizontal direction. The slide drives the electric slide rail 25, the electric slider, and the rotary cutter 28 to move along the length of the cutting groove 24, so that the rotating rotary cutter 28 continuously cuts the film 18 attached to the cutting seat 23, ultimately forming a flat cut and avoiding tearing or burrs on the film 18; after cutting is completed... When the micro servo motor 27 and linear motor 21 are turned off, the electric slide rail 25 drives the electric slider to move upward, which drives the rotary cutter 28 to return to the initial position for the next operation. If the film 18 on the roller 16 is used up, the bolt 111 can be rotated in the reverse direction through the transmission seat 112 to unscrew the bolt 111 from the first screw hole and the second screw hole. Then, the old roller 16 can be removed by sliding along the positioning block 110. After replacing the roller 16 with the new film 18, the above installation steps can be repeated to continue the maintenance and covering operation.
