Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, specifically a device for laying building waterproofing membrane rolls. Background Technology

[0002] A typical waterproof membrane laying device includes a membrane unwinding mechanism that smoothly releases the waterproof membrane, ensuring that the membrane does not wrinkle or overstretch during laying. A conveying device transports the unwound membrane to the laying position at a uniform speed. A pressure roller mechanism further compacts the laid membrane with even pressure, ensuring a tight fit against the building substrate surface, preventing air pockets, and guaranteeing waterproofing effectiveness. Some advanced laying devices may also be equipped with a heating device; for waterproof membranes requiring heat fusion, heating can be applied during laying, making the construction process more efficient and convenient. This device improves the quality and speed of waterproof membrane laying while reducing the labor intensity of workers.

[0003] A search revealed that Chinese patent CN219138186U discloses a device for laying waterproof membrane. The patent describes a method that uses an unwinding mechanism to unfold the waterproof membrane and a pressure roller to press it tightly against the base layer, thereby reducing the probability of air pockets and making the joints dense, which reduces the probability of leakage later. This technical solution saves manpower and improves the quality of waterproof membrane laying.

[0004] While this solution can reduce the occurrence of hollow areas, the installation of this device requires manual cleaning of the ground, which is slow and increases labor costs and significantly reduces work efficiency. To solve this technical problem, this utility model proposes a building waterproof membrane laying device. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This utility model provides a device for laying waterproof membrane rolls in buildings. It has the following beneficial effects:

[0016] (1) The motor drives the rotating rod to rotate, which in turn drives the chain wheel to rotate. The chain wheel rotates accordingly, and the chain wheel drives the inner rod and the cleaning roller on the fixed frame to clean the dust in front of the roll material. The exhaust fan works and sucks in the dust flying during cleaning through the air inlet pipe and dust inlet hopper. The dust is then transported to the dust collection box in the collection box through the pipeline. The dustproof net prevents dust from entering the exhaust fan. This combination solves the problem of ground dust treatment when laying waterproof roll material. Traditional methods mostly rely on manual cleaning or simple vacuuming. Manual cleaning is inefficient and incomplete. This design uses the motor and chain drive to achieve efficient rotation and cleaning of the cleaning roller. The exhaust fan and related components work together to powerfully collect dust, which effectively improves the cleanliness of the ground, speeds up the laying progress, improves the laying quality, and reduces the incidence of problems such as poor roll material adhesion caused by dust.

[0017] (2) The motor drives the rotating rod to rotate, which in turn drives the first chain wheel to rotate. The chain wheel drives the rotating rod in the second chain wheel on one side to rotate. The chain wheel rotates synchronously on the other side through gear transmission, thereby driving the outer wall extrusion rollers to rotate in opposite directions. The roll material on the storage roller is dragged out and laid through the discharge port. The spring pushes the positioning plate to prevent the roll material from deviating. The electric push rod pushes the connecting plate to move along the direction of the limit rod, which drives the adjusting roller to adjust the roll material up and down. This combination solves the problem of poor roll material conveying and flatness control during waterproof roll material laying. Traditional devices are prone to jamming and deviation during roll material conveying, and it is difficult to accurately adjust the tightness and flatness of the roll material. This design uses a combination of motor, chain, and gear to achieve stable and efficient roll material conveying. The spring and positioning plate ensure the linear movement of the roll material. The electric push rod and adjusting roller flexibly adjust the flatness of the roll material, improving laying efficiency and quality, and reducing laying defects and material waste caused by roll material problems.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: A building waterproof membrane laying device includes a trolley chassis 1. A motor 2 is fixedly connected to the top front side of the trolley chassis 1. A rotating rod 3 is fixedly connected to the output end of the motor 2. A chain wheel 4 is fixedly connected to the outer wall of the front end of the rotating rod 3. A pair of fixed frames 6 are fixedly connected to the bottom front end of the trolley chassis 1. An inner rod 7 is rotatably connected inside the two fixed frames 6. A cleaning roller 9 is fixedly connected to the outer wall of the middle of the inner rod 7. A chain wheel 8 is fixedly connected to the outer wall of one end of the inner rod 7. The chain wheel 8 is connected to the chain wheel 4 through a chain 5. A collection box 10 is fixedly connected to the top of the trolley chassis 1. An air inlet pipe 14 is provided on the right side of the collection box 10. A dust hopper 15 is fixedly connected to the end of the air inlet pipe 14. An exhaust fan 11 is fixedly connected to the top of the trolley chassis 1. The exhaust fan 11 is located on the left side of the collection box 10. A dustproof net 13 is provided inside the collection box 10. At the same time, a dust collection box 12 is slidably connected inside the collection box 10.

[0026] The motor 2 located on top of the trolley chassis 1 is started. After starting, the motor 2 outputs power, driving the connected rotating rod 3 to start rotating. The rotation of the rotating rod 3 will drive the chain wheel 4 mounted on it to rotate synchronously. Since the chain wheel 4 and the chain wheel 8 are connected by the chain 5, the chain wheel 8 will also start rotating under the drive of the chain. The rotation of the chain wheel 8 will further drive the inner rod 7 inside to rotate. The inner rod 7 is located between a pair of fixed frames 6 and is connected to the cleaning roller 9, thereby causing the cleaning roller 9 to start rotating. During the rotation of the cleaning roller 9, the dust on the ground in front of the roll material will be swept away. The exhaust fan 11 on top of the trolley chassis 1 is started. When the exhaust fan 11 is working, it will generate a strong suction force, sucking in the dust flying up during the cleaning process through the dust inlet hopper 15 on the air inlet pipe 14, and transporting it along the air inlet pipe 14 to the dust collection box 12 in the collection box 10 for collection. A dustproof net 13 is installed between the air inlet duct 14 and the exhaust fan 11. The dustproof net 13 can effectively prevent dust from entering the exhaust fan 11 and avoid damaging it. When the dust collection box 12 is full of dust, it can be pulled out for cleaning. This keeps the ground clean and effectively prevents dust from adhering to building materials, thus greatly accelerating the laying efficiency of the waterproof membrane and improving the laying quality, providing a strong guarantee for the smooth progress of the waterproofing project.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, a first chain wheel 16 is fixedly connected to the outer wall of the rotating rod 1 3, a pair of fixed plates 19 are fixedly connected to the top of the trolley chassis 1, a pair of rotating rods 20 are rotatably connected between the two fixed plates 19, and a pressing roller 21 is fixedly connected to the outer wall of each rotating rod 20. A second chain wheel 18 is fixedly connected to the outer wall of one rotating rod 20, and the second chain wheel 18 is connected to the first chain wheel 16 through a chain 2 17. Gears 22 are fixedly connected to the outer walls of both rotating rods 20, and the gears 22 mesh with each other. A discharge port 32 is opened inside the trolley chassis 1, and the discharge port 32 is located below the pressing rollers 21 on both sides. A [missing information - likely a device or component] is fixedly connected inside the trolley chassis 1. For each spring 30, a positioning plate 31 is fixedly connected to the other end of each spring 30, and the positioning plate 31 is slidably connected inside the discharge port 32. A pair of fixed brackets 33 are fixedly connected to the bottom of the trolley chassis 1, and a laying roller 34 is rotatably connected between the two fixed brackets 33. A pair of brackets 24 are fixedly connected to the top of the left end of the trolley chassis 1, and a storage roller 23 is rotatably connected between the top of the two brackets 24. A connecting frame 25 is fixedly connected to the top of the trolley chassis 1, and an electric push rod 26 is fixedly connected to the outer wall of the connecting frame 25. A connecting plate 27 is fixedly connected to the output end of the electric push rod 26, and an adjusting roller 28 is rotatably connected to the other end of the connecting plate 27. A limit rod 29 is fixedly connected to the outer wall of the connecting frame 25, and the connecting plate 27 is slidably connected to the outer wall of the limit rod 29.

[0028] Place the storage roller 23 stably on a pair of brackets 24 and let it rest on the adjusting roller 28. Then, pass one end of the storage roller 23 through the gap between the two extrusion rollers 21 and out through the discharge port 32. Finally, place it on the right side of the laying roller 34 at the bottom of the fixed frame 33. At this time, the laying roller 34 will tightly press the waterproof membrane. When the rotating rod 3 starts to rotate, the first chain wheel 16 connected to it will also rotate synchronously. The first chain wheel 16 drives the rotating rod 20 inside the second chain wheel 18 on one side to rotate through the chain 17. During the rotation of the second chain wheel 18 on one side, the gear 22 meshes with the second chain wheel 18 on the other side, so that the two second chain wheels 18 rotate towards each other. The extrusion rollers 21 on the outer wall rotate towards each other as the second chain wheels 18 rotate. Using the action of squeezing and friction, the roll material on the storage roller 23 is continuously dragged out and laid through the discharge port 32. During the process of the roll material passing through the discharge port 32, the spring 30 pushes the positioning plate 31 to move by its elastic force, thereby effectively preventing the roll material from deviating. According to the tightness of the roll material, the electric push rod 26 outside the connecting frame 25 is activated. When the electric push rod 26 is working, it pushes the connecting plate 27 to move up and down along the direction defined by the limit rod 29. The movement of the connecting plate 27 will drive the adjusting roller 28 to move up and down synchronously. The height of the roll material is precisely adjusted by the adjusting roller 28 to ensure that the roll material can be laid more neatly and evenly during the laying process, thereby improving the quality and efficiency of waterproof roll material laying and reducing laying problems and material waste caused by uneven roll material.

[0029] Working principle: When workers need to lay building waterproof membrane, they move the equipment by pushing the handle of the trolley chassis 1. First, the storage roller 23 is placed on a pair of brackets 24, then placed on the adjusting roller 28, with one end passing through the gap between the two extrusion rollers 21 and through the discharge port 32, and placed on the right side of the laying roller 34 at the bottom of the fixed frame 2 33. At the same time, the laying roller 34 presses down on the waterproof membrane. Then, the motor 2 on the top of the trolley chassis 1 is started. Under the action of the motor 2, the rotating rod 3 rotates. When the rotating rod 3 rotates... This will drive the chain wheel 4 to rotate, which in turn drives the chain wheel 8 to rotate via the chain 5. As the chain wheel 8 rotates, it will cause the internal rod 7 and the cleaning rollers 9 between the pair of fixed frames 6 to rotate, thereby sweeping away the dust in front of the roll material. At this time, the exhaust fan 11 on top of the trolley chassis 1 is activated, and the dust is sucked up and transported to the dust collection box 12 inside the collection box 10 through the dust inlet hopper 15 on the air inlet pipe 14. Simultaneously, the dustproof net 13 effectively prevents dust from entering the exhaust fan 11. The dust is then removed from the dust collection box 12 for disposal, thus preventing dust from entering the roll material. Dust adhering to building materials affects the laying of waterproof membrane. Through their coordination, the ground is kept clean, thus accelerating the laying efficiency and improving the laying quality. When the rotating rod 13 rotates, it synchronously drives the first chain wheel 16 to rotate, and through the chain 2 17, it drives the rotating rod 20 inside the second chain wheel 18 on one side to rotate. When the second chain wheel 18 on one side rotates, it drives the second chain wheel 18 on the other side to rotate through the gear 22. When the second chain wheels 18 on both sides rotate, they drive the pressing rollers 21 on the outer wall to rotate in opposite directions, thereby achieving the effect of compression and friction. The roll material on the storage roller 23 is continuously dragged out and laid through the discharge port 32. During the process, the elasticity of the spring 30 pushes the positioning plate 31 to move, preventing the roll material from deviating when passing through the discharge port 32. Then, according to the tightness of the roll material, the electric push rod 26 outside the connecting frame 25 is activated. Under the action of the electric push rod 26, the connecting plate 27 is pushed up and down. The limit rod 29 can limit the movement direction of the connecting plate 27. The connecting plate 27 drives the adjusting roller 28 to move up and down. The adjusting roller 28 is used to adjust the roll material to ensure that the roll material is laid more neatly.
