Description

Technical Field

[0002] Bridge deck seepage is a major factor leading to bridge damage. The bridge deck pavement is an important part of the bridge. The bridge deck pavement directly bears the action of vehicle loads. With the continuous increase in traffic volume, different degrees of diseases appear in the bridge pavement. If the quality of the waterproof layer, the durability of the bridge deck pavement and the life of the bridge deck are to be improved, it is necessary to focus on controlling the spraying quality of the waterproof adhesive.

[0003] Under normal circumstances, for the construction of the waterproof adhesive, the ratio is first determined and then poured into a container, and it is slightly stirred manually or mechanically for 3 - 5 minutes before it can be used. Generally, two construction methods are adopted. One is manual coating: the operator uses a roller to evenly coat the stirred waterproof adhesive on the cement concrete or the steel plate after sandblasting and rust removal. The other is machine spraying: the operator holds a spray gun, and the bent pipe at the rear of the spray gun directly sucks the solvent-based adhesive from the raw material barrel, and the solvent-based adhesive in a mist state is sprayed out of the spray gun nozzle and evenly covers the bridge deck. The second spraying is carried out 1 hour after the first spraying.

[0004] However, the waterproof adhesive stirred manually will show uneven solution or sedimentation over time, and both construction methods will result in uneven thickness of the waterproof adhesive layer.

[0032] Spraying mechanism 3, the spraying mechanism 3 is fixedly arranged at the tail end of the moving mechanism 1, and includes a water pump 31 and a spraying rack 32;

[0033] The solvent tank 2 is communicated with the water pump 31 through a solvent output pipe 4, and the water pump 31 is communicated with the spraying rack 32 through a pump output pipe 5;

[0034] Among them, the solvent tank 2 is used to store the waterproof adhesive solution, the water pump 31 is used to extract the waterproof adhesive solution and pressurize and transport it to the inside of the spraying rack 32, and the spraying rack 32 is used to evenly spray the waterproof adhesive solution onto the bridge deck.

[0035] Start the moving mechanism 1 to drive the two front wheels 12 and the two rear wheels 13 on the chassis 11 to move on the bridge deck. The waterproof adhesive solution stored in the solvent tank 2 is transported to the water pump 31 through the solvent output pipe 4. After the water pump 31 extracts the waterproof adhesive solution and pressurizes it, the solution is transported to the inside of the spraying rack 32 through the pump output pipe 5. The spraying mechanism 3 is fixed at the tail end of the moving mechanism 1, and the nozzles 32A on the spraying rack 32 evenly spray the pressurized waterproof adhesive solution onto the bridge deck.

[0036] Through the stable supply and uniform spraying of the waterproof adhesive solution, the construction efficiency and effect are significantly improved, and the moving mechanism 1 provides flexible operability. The connection method between the water pump 31 and the spraying rack 32 ensures the continuous pressurization and transportation of the solution, and the design of the spraying rack 32 ensures the uniform distribution of the solution.

[0037] In this embodiment, a motor 6 is arranged in front of the solvent tank 2 and is fixed on the upper surface of the chassis 11;

[0038] A transmission flywheel 21 is arranged on one side surface of the solvent tank 2;

[0039] A belt 7 is arranged in a circle on the same plane as the transmission flywheel 21, and the motor 6, the transmission flywheel 21 and the water pump 31 are connected through the belt 7;

[0040] The motor 6 is used to drive the transmission flywheel 21 and the water pump 31 to work, and the belt 7 is used to transmit the power of the motor 6 to the transmission flywheel 21 and the water pump 31.

[0041] When starting the motor 6, the motor 6 is fixed on the upper surface of the chassis 11. A transmission flywheel 21 is provided on one side of the solvent tank 2. The transmission flywheel 21 transmits power through a belt 7 on the same plane, and the belt 7 also connects the motor 6 and the water pump 31. As the motor 6 operates, the belt 7 transmits the power of the motor 6 to the transmission flywheel 21 and the water pump 31, driving the water pump 31 to extract the waterproof adhesive solution in the solvent tank 2 and pressurize and transport it to the inside of the spraying frame 32.

[0042] The motor 6 transmits power to the transmission flywheel 21 and the water pump 31 through the belt 7, ensuring the efficient operation of the device. The combination of the motor 6 with the solvent tank 2, the transmission flywheel 21 and the water pump 31 improves the power transmission efficiency and stability of the device, optimizes the extraction and spraying process of the waterproof adhesive solution, thereby enhancing the overall construction efficiency and effect.

[0043] In this embodiment, a stirring paddle 22 is provided in the solvent tank 2, and the stirring paddle 22 is connected to the transmission flywheel 21 through a rotating shaft 23.

[0044] A stirring paddle 22 is provided in the solvent tank 2 and is connected to the transmission flywheel 21 through a rotating shaft 23.

The stirring paddle 22 continuously stirs in the solvent tank 2, keeping the waterproof adhesive solution in a uniformly mixed state.

[0045] Through the continuous operation of the stirring paddle 22, the waterproof adhesive solution in the solvent tank 2 always remains uniformly mixed, preventing precipitation and stratification phenomena, ensuring the consistency of the solution throughout the construction process, improving the spraying effect and construction quality. The connection method between the stirring paddle 22 and the transmission flywheel 21 simplifies the structural design and enhances the reliability and durability of the device.

[0046] As a preference of the above embodiment, the diameter of the spraying frame 32 gradually decreases from the middle to both ends, and both ends are in a closed state.

[0047] During the spraying construction process, the waterproof adhesive solution is transported to the inside of the spraying frame 32 through the water pump 31. The spraying frame 32 is designed with a diameter that gradually decreases from the middle to both ends, and both ends are in a closed state. When the solution enters the spraying frame 32, through the gradually decreasing diameter, the solution pressure gradually increases, and finally it is sprayed onto the bridge surface through the uniformly distributed nozzles 32A.

[0048] The design of the spraying frame 32 ensures uniform pressure of the waterproof adhesive solution throughout the spraying process, avoiding uneven spraying. The structure with a gradually decreasing diameter enables the solution to more effectively cover the construction area, and the closed ends prevent leakage and waste of the solution, thereby improving the construction efficiency and quality.

[0049] In this embodiment, two telescopic joints 32B are correspondingly arranged on the spraying frame 32, and the length of the spraying frame 32 can be manually adjusted through the telescopic joints 32B.

[0051] In this embodiment, a number of nozzles 32A are equidistantly arranged on the spraying frame 32.

[0052] A number of nozzles 32A are equidistantly arranged on the spraying frame 32, ensuring that the waterproof adhesive solution can uniformly cover the construction area during the spraying process. The uniform distribution of the nozzles 32A effectively avoids the problems of uneven spraying and local overdosage, improves the construction quality. Through this configuration, the entire spraying process is more efficient, reducing the waste of the waterproof adhesive solution, and at the same time ensuring the uniformity and consistency of the construction surface.

[0053] As an optimization of the above embodiment, a control valve 51 is arranged in the middle of the pump output pipe 5. The control valve 51 is set as a spherical control valve and is used to adjust the pressure of the water pump 31 on the inside of the spraying frame 32.

[0054] By setting the control valve 51, the spraying pressure of the waterproof adhesive solution can be precisely controlled during the spraying process, ensuring the stability and consistency of the spraying process. The spraying effect can be flexibly adjusted according to actual needs, reducing the waste of the waterproof adhesive solution, and improving the construction quality and efficiency.

[0055] In this embodiment, the spraying frame 32 is made of metal material.

[0056] The metal material provides high strength and durability, and can withstand various mechanical stresses and environmental conditions during construction, ensuring that the spraying frame 32 is not easily deformed or damaged during long-term use, and improving the service life and reliability of the device. At the same time, the spraying frame 32 made of metal material has good corrosion resistance and is suitable for various complex construction environments, ensuring uniform spraying of the waterproof adhesive solution and high-quality construction effects.
