[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figures 1 to 6 As shown, the present invention provides a device for wet-laying waterproof membrane, including a frame 1, which is formed by welding several square tubes together. The frame 1 is equipped with a walking system 2, a wet-laying mechanism 3, and an automatic control system 4. The walking system 2, the wet-laying mechanism 3, and the automatic control system 4 work together to complete the automatic wet-laying construction of the waterproof membrane. By integrating the walking system 2, the wet-laying mechanism 3, and the automatic control system 4 through the frame 1, the three systems are coordinated and linked to achieve the automatic wet-laying construction of the waterproof membrane, eliminating the cumbersome process of coordinating multiple devices and improving the continuity of construction.

[0052] Specifically, the walking system 2 includes wheels 21, handrails 22, and travel sensing and braking devices;

[0053] Wheels 21 are mounted on the underside of both sides of the frame 1;

[0054] Handrail 22 is fixed to the upper part of one end of frame 1;

[0055] The travel sensing and braking device is fixed on the roller of wheel 21. It is used to count the travel distance of the device and control the start and stop of the spraying system. The walking system 2 can accurately count the travel distance of the device through the cooperation of the travel sensing and braking device and the roller of wheel 21. At the same time, it can directly control the start and stop of the spraying system, realize the linkage between walking and spraying, avoid ineffective spraying when the device stops, and reduce material waste.

[0056] like Figures 1 to 6 As shown, the wet laying mechanism 3 includes a water bucket 31, a material bucket 32, a mixing bucket 33, a spray pipe 34, a spray nozzle 342, a roll unwinding roller 35, an air drain brush 36, and a pipeline pump 37.

[0057] Water bucket 31 and material bucket 32 ​​are respectively installed on the upper two sides of the frame 1. Water bucket 31 is provided with a water inlet on the top, and material bucket 32 ​​is provided with a material inlet on the top.

[0058] The mixing tank 33 is installed in the middle of the frame 1, and the mixing tank 33 is connected to the water tank 31 and the material tank 32 through pipelines;

[0059] The pipeline pump 37 is connected to the mixing tank 33;

[0060] One end of the shotcrete pipe 34 is connected to the pipeline pump 37, and several shotcrete nozzles 342 are installed on the outer surface of the shotcrete pipe 34.

[0061] The shotcrete nozzle 342 is positioned facing the construction substrate.

[0062] The unwinding roller 35 is rotatably mounted on one side of the middle part of the frame 1;

[0063] The drain brush 36 is arranged along the width of the vehicle. The wet laying mechanism 3 integrates the entire process components from the water bucket 31, material bucket 32, mixing bucket 33 to the drain brush 36. Several spray nozzles 342 are installed on the spray pipe 34 to realize the integrated operation of adhesive mixing, conveying, spraying and roll unwinding and compaction, thereby improving the efficiency of wet laying construction.

[0064] Furthermore, the inner walls on both sides of the frame 1 are rotatably connected to a rotating shaft 361. A bracket 365 is fixedly connected to the outer surface of the rotating shaft 361. The drain brush 36 is fixedly connected to the bracket 365. Through the rotating connection between the rotating shaft 361 and the frame 1, the bracket 365 and the drain brush 36 are driven to rotate synchronously, providing a basic structure for the angle adjustment of the drain brush 36, so that the drain brush 36 can adapt to the angle requirements of different construction conditions.

[0065] like Figures 1 to 6 As shown, one end of the bracket 365 is rotatably connected to an adjustable support rod 362. One end of the adjustable support rod 362 has a through-type fixing groove 366, and one end of the bracket 365 has three through-type fixing grooves 363. One of the fixing grooves 363 and the fixing groove 366 together movably insert a pin 364. Through the cooperation of the fixing groove 366, the multi-position fixing groove 363 and the pin 364, the adjustable support rod 362 and the bracket 365 can be fixed in multiple positions, thereby precisely adjusting the working angle of the drain brush 36 to adapt to different thicknesses of roll materials and the flatness of the base layer.

[0066] It is worth noting that the adjustable strut 362, bracket 365 and the square tube of frame 1 form a triangular support structure. The triangular support structure formed by the adjustable strut 362, bracket 365 and the square tube of frame 1 can stably lock the adjustment angle of the air-draining brush 36, avoid angle deviation due to vibration and pressure during construction, and ensure the air-draining and compaction effect.

[0067] like Figures 1 to 6 As shown, the unwinding roller 35 moves with the device to achieve synchronous unwinding, and the unwinding speed matches the device's travel speed;

[0068] The position of the air-draining brush 36 corresponds to that of the roll material unwinding roller 35. The unwinding speed of the roll material unwinding roller 35 is matched with the traveling speed of the device. The position of the air-draining brush 36 corresponds to that of the roll material unwinding roller 35, so that the roll material is immediately compacted by the air-draining brush 36 after unwinding, avoiding roll material wrinkles and air bubbles, and improving the flatness of the laying.

[0069] It is worth emphasizing that the automated control system 4 includes a laser displacement sensor 41, an intelligent control device 42, a regulating valve 341, an automatic batching device 43, and an infrared emitter 44.

[0070] The laser displacement sensor 41 is mounted on the frame 1, and the detection direction of the laser displacement sensor 41 is perpendicular to the construction substrate;

[0071] The automatic batching device 43 is installed on the upper part of the frame 1 and is located between the water tank 31 and the material tank 32. The automatic batching device 43 is connected to the water tank 31, the material tank 32 and the mixing tank 33 through pipelines and circuits respectively.

[0072] The intelligent control device 42 is installed in the middle of the frame 1. The intelligent control device 42 is used to receive feedback data and adjust the operating parameters of each component.

[0073] The regulating valve 341 is connected in series with the shotcrete pipe 34;

[0074] Infrared transmitter 44 is installed on one side of the front end of frame 1. The automatic control system 4 uses laser displacement sensor 41 to vertically detect the thickness of the base adhesive. In conjunction with automatic batching device 43 and regulating valve 341, it achieves precise control of batching and spraying volume. At the same time, infrared transmitter 44 ensures accurate movement trajectory, improving the automation and accuracy of construction.

[0075] like Figures 1 to 6 As shown, the intelligent control device 42 is electrically connected to the laser displacement sensor 41, the stroke sensing and braking device, the regulating valve 341, and the automatic batching device 43. The intelligent control device 42 is electrically connected to core components such as the laser displacement sensor 41 and the stroke sensing and braking device, forming an automated control closed loop. This enables real-time adjustment of the operating parameters of each component without manual intervention, reducing operational difficulty and ensuring the stability of construction parameters.

[0076] Working principle and process: During construction, the automatic batching device 43 first delivers water from bucket 31 and binder from bucket 32 ​​to mixing tank 33 according to the ratio; the operator pushes the device through handle 22, and the wheels 21 drive the frame 1 to move forward. The stroke sensing and braking device counts the distance traveled as the rollers of wheels 21 rotate and feeds it back to the intelligent control device 42; the intelligent control device 42 starts the pipeline pump 37, which delivers the mixed binder to the spray pipe 34, and sprays it onto the construction base through the spray nozzle 342. The laser displacement sensor 41 is vertical. The adhesive coating thickness is detected and the data is fed back. The intelligent control device 42 adjusts the opening of the regulating valve 341 according to the data to control the amount of spraying. The roll unwinding roller 35 unwinds the waterproof membrane synchronously with the movement of the device. The air venting brush 36 presses the membrane firmly onto the adhesive surface and vents air at a preset angle through the cooperation of the rotating shaft 361, the bracket 365 and the adjustable support rod 362. The infrared transmitter 44 assists in calibrating the movement direction of the device. The entire process is carried out by the intelligent control device 42 linking the various components of the walking system 2 and the wet laying mechanism 3 to realize the automatic wet laying construction of the waterproof membrane.
