Description

Technical Field

[0001] This utility model relates to the field of highway construction equipment technology, specifically to a membrane laying device for highway engineering. Background Technology

[0002] In the construction process of highway engineering, the road surface is mainly divided into two categories: concrete pouring and asphalt pouring. After the concrete road surface is poured, the concrete needs a period of time to solidify. During this period, the uncured concrete needs appropriate moisture to solidify properly and increase its hardness. Therefore, a transparent film needs to be laid on the road surface to prevent moisture loss and road surface cracking, while also protecting the road surface from external influences.

[0003] Currently, the curing membrane laying process involves manual installation followed by manual compaction using tools. This manual method is inefficient, requires two separate steps, is time-consuming, and often necessitates multiple people working together. Furthermore, the curing membrane, mostly made of plastic, is lightweight and easily affected by wind during installation, causing previously laid but not compacted membrane to shift or fold, requiring re-laying and further reducing efficiency. Additionally, the laying is done after concrete pouring; initially, the concrete retains good moisture, but as the laying progresses... As time progresses, the concrete at the end of the road will not be cured and will be exposed to the air for a long time. The moisture inside will gradually evaporate, and the moisture content will no longer meet the strength requirements of the road surface. The longer working time will affect the curing of the road surface later. In addition, the road construction is located in the outside world, and it is impossible to guarantee that the road surface is clean. Small foreign objects such as stones and gravel will remain on the road surface. These foreign objects are small and exist over a large area. Manual cleaning is not only time-consuming, but also cannot guarantee thorough cleaning. If these foreign objects are not removed, they will seriously reduce the flatness of the curing membrane and affect the final quality of the road. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a film-laying device for highway engineering, comprising a frame, a placement frame fixedly connected to the frame, a film-rolling roller on the placement frame, the film-rolling roller rotatably cooperating with the placement frame, a roller frame at one lower end of the frame, a pressure roller rotatably connected in the roller frame, a water tank fixedly connected to the upper end of the frame, a water supply pump at one end of the water tank, a sprinkler pipe at the lower end of the frame, the water tank being connected to the sprinkler pipe via the water supply pump, a recycling hood at the other lower end of the frame, and a waste bin cooperating with the recycling hood at the top of the frame.

[0008] Preferably, the upper end of the roller frame is provided with a positioning rod, the frame is provided with a positioning hole that slides with the positioning rod, and the roller frame is provided with a pressure spring. The pressure spring is sleeved on the positioning rod so that the pressing roller is always pressed and tightened with the curing film, ensuring the quality of the laying.

[0009] In a further preferred embodiment, the water tank is provided with an observation port, which contains an observation glass to facilitate confirmation of the water volume and ease of use.

[0010] In a further preferred embodiment, one end of the recycling hood is provided with an air outlet hood, and one end of the waste bin is provided with a fan that works in conjunction with it. The air outlet hood is connected to the waste bin through the fan to provide power and make the equipment more powerful.

[0011] In a further preferred embodiment, a sweeping frame is provided between the recycling hood and the exhaust hood. The upper end of the sweeping frame is fixedly connected to the machine frame, and the lower end is rotatably connected to a sweeping roller. The sweeping roller is equipped with a sweeping brush to improve the sweeping effect and ensure the final quality of the road surface.

[0012] In a further preferred embodiment, one end of the pressing roller is fixedly connected to a drive wheel through the roller frame, and one end of the cleaning roller is fixedly connected to a driven wheel through the cleaning frame. The drive wheel and the driven wheel are equipped with transmission belts that cooperate with them, thereby reducing power contact and saving resources.

[0014] In a further preferred embodiment, a scraper plate is fixedly connected to the lower end of the recycling hood to prevent foreign matter residue and ensure cleaning quality.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a membrane laying device for highway engineering, which has the following beneficial effects:

[0017] 1. This utility model uses a frame as the main body of the equipment, and a placement frame and a film-rolling roller are used to place the curing film. The rotation of the film-rolling roller slowly unfolds the curing film, making it easy to lay out. The roller frame and the pressing roller work together to compact the laid-out curing film. The equipment for laying and pressing the film is combined into one, and the film is pressed out at the same time as the film is laid, saving process time and avoiding the need to re-lay the laid curing film due to external influences, thus ensuring construction efficiency.

[0018] 2. By setting up a water tank to store clean water and providing power through a water pump, water is sprayed onto the ground through a sprinkler pipe in conjunction with the water pump and water tank. This structure is placed together with the membrane laying equipment. If the concrete in the later section of the road surface is not moist enough before laying the membrane, water can be added even if necessary, without stopping the laying process, thus ensuring the quality of the concrete.

[0019] 3. By setting up recycling hoods and waste bins to attract small foreign objects such as gravel and sand, negative pressure is provided by a blower, and air is blown through the exhaust hood. In conjunction with the suction of the recycling hood, foreign objects on the road surface are absorbed before paving. Furthermore, the combination of sweeping frame, sweeping roller and sweeping brush is used to remove foreign objects that are tightly attached and difficult to blow away, thereby cleaning the road surface before the maintenance membrane is laid and ensuring the final quality of the road surface.

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.

[0027] Example 1:

[0028] Please see Figure 1 A film-laying device for highway engineering includes a frame 1, a placement frame 2 fixedly connected to the frame 1, a film-rolling roller 3 on the placement frame 2, the film-rolling roller 3 rotatably cooperating with the placement frame 2, a roller frame 4 at one lower end of the frame 1, a pressure roller 5 rotatably connected in the roller frame 4, a water tank 6 fixedly connected to the upper end of the frame 1, a water supply pump 7 at one end of the water tank 6, a sprinkler pipe 8 at the lower end of the frame 1, the water tank 6 being connected to the sprinkler pipe 8 through the water supply pump 7, a recycling hood 9 at the other lower end of the frame 1, and a waste bin 10 cooperating with the recycling hood 9 at the top of the frame 1.

[0029] Please see Figure 1-3 In this embodiment, the upper end of the roller frame 4 is provided with a positioning rod 11, the frame 1 is provided with a positioning hole 12 that slides with the positioning rod 11, the roller frame 4 is provided with a pressure spring 13, the pressure spring 13 is sleeved on the positioning rod 11, the positioning rod 11 cooperates with the positioning hole 12 and slides under the restriction of the positioning hole 12, so that the roller frame 4 can drive the pressing roller 5 to move up and down, and the setting of the pressure spring 13 makes the roller frame 4 always bear the downward thrust, so that the pressing roller 5 always presses the curing film 27 tightly.

[0030] Please see Figure 3 In this embodiment, the water tank 6 is provided with an observation port 14, and an observation glass 15 is provided in the observation port 14. The water content inside the water tank 6 can be observed through the observation port 14 and the observation glass 15, so as to facilitate timely water replenishment.

[0031] Please see Figure 2 and Figure 5 In this embodiment, one end of the recycling hood 9 is provided with an air outlet hood 16, and one end of the waste bin 10 is provided with a fan 17 that works in conjunction with it. The air outlet hood 16 is connected to the waste bin 10 through the fan 17. The fan 17 provides negative pressure, causing airflow to blow out from the air outlet hood 16, which blows away foreign objects on the road. The air outlet hood 16 is connected to the recycling hood 9. Under the action of the fan 17, the gas blown out by the air outlet hood 16 comes from the gas collected by the recycling hood 9, and the foreign objects are sucked in through the recycling hood 9.

[0032] Please see Figure 1-4In this embodiment, a cleaning frame 18 is provided between the recovery hood 9 and the air outlet hood 16. The upper end of the cleaning frame 18 is fixedly connected to the frame 1, and the lower end is rotatably connected to a cleaning roller 19. A cleaning brush 20 is provided on the cleaning roller 19. One end of the pressing roller 5 passes through the roller frame 4 and is fixedly connected to a drive wheel 21. One end of the cleaning roller 19 passes through the cleaning frame 18 and is fixedly connected to a driven wheel 22. A transmission belt 23 is provided on the drive wheel 21 and the driven wheel 22 to cooperate with them. The pressing roller 5 moves... When rotating, it will drive the drive wheel 21 to rotate. The drive wheel 21 and the driven wheel 22 are connected by a transmission belt 23. When the drive wheel 21 rotates, it will cause the transmission belt 23 to move, thereby driving the driven wheel 22 to rotate. When the driven wheel 22 rotates, it provides power for the rotation of the sweeping roller 19, causing the sweeping roller 19 to rotate on the sweeping frame 18. The sweeping roller 19 drives the sweeping brush 20 to rotate. With the sweeping frame 18 fixed, it contacts the ground and sweeps the foreign objects on the ground towards the recycling hood 9.

[0033] Please see Figure 1 In this embodiment, the lower end of the frame 1 is provided with a movable wheel 24, and the end of the frame 1 away from the pressure roller 5 is provided with a pull handle 25. The frame 1 contacts the ground through the movable wheel 24 to support the equipment. The friction between the movable wheel 24 and the ground is small, which facilitates movement. The equipment can be moved by pulling the frame 1 through the pull handle 25.

[0034] Please see Figure 5 In this embodiment, a scraper plate 26 is fixedly connected to the lower end of the recycling cover 9. When the equipment moves, the recycling cover 9 moves on the ground along with the equipment and contacts the ground through the scraper plate 26. The scraper plate 26 introduces foreign objects on the ground into the recycling cover 9 to prevent foreign objects from flowing between the recycling cover 9 and the ground.

[0035] Example 2:

[0036] Please see Figure 1-3When using the equipment, prepare the materials needed for the work. Install the film-rolling roller 3 with the curing film 27 onto the placement frame 2, allowing the film-rolling roller 3 to rotate on the placement frame 2. The curing film 27 is a label shown in the attached drawing. Observe the water content inside the water tank 6 through the observation port 14 and the observation glass 15. Add sufficient water to the water tank 6. Turn on the power to start the equipment. Pull out the curing film 27 from the film-rolling roller 3, allowing one end of the curing film 27 to pass under the pressure roller 5. The positioning rod 11 engages with the positioning hole 12, allowing the positioning rod 11 to slide under the restriction of the positioning hole 12. This allows the roller frame 4 to drive the pressure roller 5 to move up and down. The pressure spring 13 ensures that the roller frame 4 always bears a downward thrust. The pressure roller 5 keeps the curing film 27 pressed firmly against the ground, preventing gaps between the curing film 27 and the ground. The frame 1 is in contact with the ground via the moving wheels 24, supporting the equipment. The moving wheels 24 have low friction with the ground, facilitating movement. The frame 1 is moved by pulling the handle 25, and the direction of movement is opposite to the direction in which the curing film 27 is unfolded. The pressure roller 5 keeps the curing film 27 pressed against the ground and rotates due to friction. The curing film 27 in contact with the ground does not move, thus pulling the subsequent curing film 27. This causes the film roll 3 to rotate on the placement frame 2, continuously unfolding new curing film 27, which is then pressed firmly against the ground by the pressure roller 5, protecting the ground.

[0037] Example 3:

[0038] Please see Figure 2-5Based on the above embodiment 2, when the equipment is pulled to lay the curing membrane 27, the blower 17 and water pump 7 are started to clean and add water to the ground before it comes into contact with the curing membrane 27. The moving equipment will first come into contact with the ground through the air outlet hood 16. The blower 17 will work to generate negative pressure, causing airflow to blow out from the air outlet hood 16. If there are foreign objects such as gravel on the ground, the airflow from the air outlet hood 16 will blow the foreign objects on the road surface, causing them to move towards the recovery hood 9. In addition, at this time, the foreign objects on the road surface are located between the air outlet hood 16 and the recovery hood 9. The exhaust hood 16 is connected to the recovery hood 9. Under the action of the fan 17, the gas blown out by the exhaust hood 16 comes from the gas collected by the recovery hood 9. Therefore, the recovery hood 9 will also generate suction due to the airflow, sucking foreign objects into the recovery hood 9. Moreover, when the equipment moves, the pressure roller 5 will also move. When the equipment moves, that is, when the pressure roller 5 rotates, it will drive the drive wheel 21 to rotate. The drive wheel 21 and the driven wheel 22 are connected by a transmission belt 23. When the drive wheel 21 rotates, it will cause the transmission belt 23 to move, thereby driving the driven wheel 22. When the driven wheel 22 rotates, it provides power for the rotation of the sweeping roller 19, causing the sweeping roller 19 to rotate on the sweeping frame 18. The sweeping roller 19 drives the sweeping brush 20 to rotate. With the sweeping frame 18 fixed, the brush contacts the ground, removing foreign objects from the ground and preventing them from sticking to the ground. The brush sweeps the foreign objects into the collection hood 9, and the collection hood 9 contacts the ground through the scraper plate 26. The scraper plate 26 guides the foreign objects on the ground into the collection hood 9, preventing them from falling out of the collection hood. The airflow passes between the cover 9 and the ground. Foreign objects entering the recycling cover 9 are drawn into the waste bin 10 by the airflow under the influence of negative pressure. The waste bin 10 has the same structure as a vacuum cleaner on the market, which can contain foreign objects and expel gas. Its structure and principle are well known technology and will not be described in detail here. Under the action of the water supply pump 7, the water in the water tank 6 will be introduced into the sprinkler pipe 8 and sprayed on the ground. The ground after the foreign objects are treated is kept clean, and the viscosity is increased after adding water, which makes it easier to adhere to the maintenance film 27.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
