After the laying work is completed, the dust collection cabinet can be pulled out to clean the dust inside. However, the above technical solution still has the following defects: since there are usually stubborn impurities such as stones and concrete protrusions on the laying surface, the brush cannot completely remove them, resulting in defects such as bulges and unevenness in the waterproof membrane after laying.

[0025] like Figures 1-4 As shown, the embodiment provides a waterproof membrane laying device for building construction, including a vehicle body 1, an unwinding mechanism 2, a cleaning mechanism 3, and a main controller 4. The unwinding mechanism 2 and the cleaning mechanism 3 are both electrically connected to the main controller 4. The unwinding mechanism 2 includes a storage box 21, an unwinding roller 22, a conveying roller 23, and a compaction module 24. The storage box 21 is fixed to the vehicle body 1. The unwinding roller 22 is rotatably connected inside the storage box 21. A waterproof membrane 5 is wound on the unwinding roller 22. Conveying rollers 23 are provided on both sides of the waterproof membrane 5, and the conveying rollers 23 are rotatably connected to the inner wall of the storage box 21. The compaction module 24 is located at the bottom of the vehicle body 1, and the free end of the waterproof membrane 5 passes through the gap between the two conveying rollers 23 and then contacts the compaction module 24. 4. The cleaning mechanism 3 includes a rotary motor 31, a rotating shaft 32, a connecting rod 33, a steel wire rope 34, a tension sensor 35, a hydraulic push rod 36, an impact plate 37, and a cleaning part 38. The rotary motor 31 is fixed on the vehicle body 1. The output end of the rotary motor 31 is connected to the rotating shaft 32. The two ends of the rotating shaft 32 are fixed with connecting rods 33. A through hole is opened in the center of the connecting rod 33. One end of the steel wire rope 34 is connected to the vehicle body 1. The other end of the steel wire rope 34 passes through the through holes on the two connecting rods 33 in sequence and is connected to the tension sensor 35 located on the vehicle body 1. The hydraulic push rod 36 is vertically fixed on the vehicle body 1. The output end of the hydraulic push rod 36 is connected to the impact plate 37. The cleaning part 38 is also provided on the vehicle body 1.
[0026] In this embodiment, the vehicle body 1 can move, thereby driving the unwinding mechanism 2 and the cleaning mechanism 3 to move synchronously, so as to achieve continuous laying of waterproof membrane 5 and improve construction efficiency. The unwinding mechanism 2 can unwind the waterproof membrane 5 during the movement of the vehicle body 1 to complete the laying operation. The storage box 21 is fixed on the top of the vehicle body 1. The storage box 21 has a storage cavity inside, and the unwinding roller 22 and the conveying roller 23 are both located inside the storage cavity. The two conveying rollers 23 are respectively attached to the front and back sides of the waterproof membrane 5, thereby clamping the waterproof membrane 5 to achieve a fixing effect. The compaction module 24 can press the free end of the waterproof membrane 5 to the ground to achieve a better fit and ensure the laying quality. Since the free end of the waterproof membrane 5 is pressed to the ground, the bottom surface of the waterproof membrane 5 is firmly bonded to the laying surface, so that the vehicle body 1 can pull the unwinding roller 22 to rotate to achieve unwinding when it moves. The cleaning mechanism 3 can clean dust, stones, and other impurities from the road surface, thus avoiding defects such as hollow areas, wrinkles, and weak adhesion after the waterproof membrane is laid. The rotary motor 31 is fixed at the front end of the vehicle body 1, and its power shaft is horizontally arranged. The rotating shaft 32 is horizontally positioned below the vehicle body 1, and the rotary motor 31 drives the rotating shaft 32 to rotate. The connecting rod 33 is a straight rod, with two connecting rods 33 arranged parallel to each other and perpendicular to the rotating shaft 32. The central axis of the through hole coincides with the central axis of the connecting rod 33. When the connecting rod 33 is in a vertical position, the wire rope 34 is in close contact with the paved surface, allowing the wire rope 34 to scrape away stubborn impurities adhering to the paved surface during the movement of the vehicle body 1. When the wire rope 34 encounters impurities that are difficult to scrape off, the tension sensor 35 connected to the wire rope 34 will experience a large tension. When the tension exceeds the set value, the vehicle body 1 will temporarily stop moving, and the main controller 4 will control the hydraulic push rod 36 to start. The hydraulic push rod 36 will drive the impact plate 37 to impact the ground and break up the impurities. At this time, the wire rope 34 can scrape them off. The hydraulic push rod 36 is arranged vertically, and the impact plate 37 is a flat structure. The impact plate 37 is located below the hydraulic push rod 36, which allows the hydraulic push rod 36 to drive the impact plate 37 to move up and down to achieve the impact operation. The impact plate 37 is located directly above the wire rope 34. The main controller 4 can be a microcontroller, a PLC, or other digital processor, used to control the unwinding mechanism 2 and the cleaning mechanism 3 to work together. In addition, all the components used in this embodiment are commercially available.
[0027] Specifically, the compaction module 24 includes a rotating seat 241, a U-shaped plate 242, a first spring 243, a mounting frame 244, and a compaction roller 245. The rotating seat 241 is fixed to the bottom of the vehicle body 1. The output end of the rotating seat 241 is connected to the U-shaped plate 242. The mounting frame 244 is slidably connected to the inner side of the U-shaped plate 242. One end of the first spring 243 is connected to the mounting frame 244, and the other end of the first spring 243 is connected to the U-shaped plate 242. The compaction roller 245 is rotatably connected to the mounting frame 244.
[0028] In this embodiment, the rotating seat 241 is existing technology, as disclosed in Chinese Utility Model Patent No. CN219389224U, which can drive the U-shaped plate 242 to rotate. The mounting frame 244 is also a U-shaped structure, and the mounting frame 244 can slide inside the U-shaped plate 242. When the rotating seat 241 drives the U-shaped plate 242 to rotate to a horizontal state, the mounting frame 244 and the compaction roller 245 also rotate to a horizontal state. At this time, the first spring 243 is in a relaxed state (i.e., uncompressed state). When the U-shaped plate 242 rotates to a vertical state, the compaction roller 245 gradually contacts the ground, which will cause the first spring 243 to be compressed. Then, under the action of the first spring 243, the compaction roller 245 can press the waterproof membrane 5 firmly onto the paving surface, and make the bottom surface of the waterproof membrane 5 firmly bonded to the paving surface.
[0029] Specifically, the compaction module 24 also includes an electric telescopic rod 246, a knife holder 247, and a cutting knife 248. The electric telescopic rod 246 is fixed to the bottom of the vehicle body 1, and the output end of the electric telescopic rod 246 is connected to the knife holder 247. The cutting knife 248 is installed on the knife holder 247.
[0030] In this embodiment, the electric telescopic rod 246 is arranged horizontally, capable of driving the blade holder 247 and the cutting blade 248 to move left and right, thereby cutting the waterproof membrane 5. The length of the cutting blade 248 should be slightly greater than the width of the waterproof membrane 5 to ensure that the waterproof membrane 5 can be cut in one go. The cutting blade 248 is detachably connected to the blade holder 247, facilitating replacement if the cutting blade 248 is damaged.
[0031] Specifically, the cleaning unit 38 also includes a sweeping motor 381, a sweeping brush 382, a suction pipe 383, and a suction pump 384. The sweeping motor 381 is fixed on the vehicle body 1. The sweeping brush 382 is connected to the drive shaft of the sweeping motor 381. The suction pipe 383 is provided on the side of the sweeping brush 382 near the storage box 21. The top of the suction pipe 383 is connected to the suction pump 384 located on the vehicle body 1.
[0032] In this embodiment, the sweeping motor 381 is vertically fixed to the vehicle body 1, and the power shaft of the sweeping motor 381 is arranged vertically downwards. The sweeping brush 382 has a disc-shaped structure, and the bottom of the sweeping brush 382 is in contact with the paved surface. The sweeping motor 381 can drive the sweeping brush 382 to rotate, thereby sweeping particulate impurities and dust on the paved surface to one side of the vehicle body 1. The suction pipe 383 is arranged vertically, and the input end of the suction pump 384 is connected to the top end of the suction pipe 383, which can create a negative pressure at the opening of the suction pipe 383, thereby sucking away residual dust on the ground and in the air to reduce dust pollution. The output end of the suction pump 384 is connected to a dust collection box, which is equipped with a filter screen to filter and store dust in the air, while clean air is discharged from the exhaust port of the dust collection box.
[0033] Specifically, a limiting plate 39 is provided on the side of the rotary motor 31 near the storage box 21, and the limiting plate 39 is connected to the vehicle body 1.
[0034] In this embodiment, the limiting plate 39 is arranged vertically, and the limiting plate 39 can limit the rotation range of the connecting rod 33. When the connecting rod 33 rotates to the vertical state, it abuts against the limiting plate 39. Furthermore, when stubborn impurities pull the wire rope 34, the limiting plate 39 can also provide auxiliary support for the connecting rod 33.
[0035] Working principle: When in use, move the vehicle body 1 to the position to be constructed and pull the free end of the waterproof membrane 5 to make it adhere to the ground. At this time, start the rotating seat 241. The rotating seat 241 drives the U-shaped plate 242 to rotate to the vertical position. The rotation of the U-shaped plate 242 drives the mounting frame 244 and the compaction roller 245 to rotate synchronously. Then, the compaction roller 245 presses the free end of the waterproof membrane 5 and adheres it to the paving surface. At the same time, the rotating motor 31 drives the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the connecting rod 33 to rotate to the vertical position, and makes the steel wire rope 34 adhere to the paving surface. Then, the vehicle body 1 moves. During this movement, the waterproof membrane 5 pulls the unwinding roller 22 to rotate, completing the automatic unwinding. Simultaneously, the steel wire rope 34 scrapes away impurities in the forward direction of the vehicle body 1. When the steel wire rope 34 encounters impurities that are difficult to scrape off, the tension sensor 35 gradually increases. When the tension exceeds the set value, the vehicle body 1 temporarily stops moving, and the main controller 4 controls the hydraulic push rod 36 to start. The hydraulic push rod 36 drives the impact plate 37 to knock down and crush the impurities. After the solid impurities are crushed, the tension on the steel wire rope 34 decreases. At this time, the impact plate 37 is lifted, and the vehicle body 1 continues to move. Then, the sweeping motor 381 drives the sweeping brush 382 to sweep the impurities on the paved surface to one side of the vehicle body 1. At the same time, the dust pump 384 creates a negative pressure at the bottom of the suction pipe 383 to suck away the residual dust on the paved surface and the dust floating in the air, keeping the paved surface clean and reducing dust pollution.
[0036] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
