Description

Technical Field

[0001] This utility model belongs to the field of civil engineering construction technology, specifically relating to a filling and water replenishment device for earthwork roadbed construction. Background Technology

[0002] During the construction of earthwork roadbed, after paving and before compaction, water mist or fine water streams need to be sprayed onto the fill material (soil) to bring its moisture content to or near the optimal compaction moisture content, thereby obtaining the best compaction effect and roadbed quality.

[0003] The most common water replenishment devices include water trucks, which are the most traditional and common method. They utilize an onboard water tank and pump, spraying water through nozzles at the rear or sides of the vehicle. Their advantages include high mobility, allowing free movement along the roadbed and adaptability to different road sections and terrains; and low technical requirements, requiring only a driver to control direction and spray volume. Disadvantages include poor spray uniformity, easily causing localized over-wetting or under-wetting, and significant susceptibility to external environmental factors.

[0004] Alternatively, fogging machines utilize high-powered fans to generate high-speed airflow, atomizing water pumped by a water pump into extremely fine droplets and spraying them remotely. The advantages of these fogging machines are their very large coverage area; a single unit can cover a wide roadbed; and their excellent water replenishment effect: the fine water mist particles are easily absorbed by the soil, reducing surface runoff and compaction, and minimizing drift loss. The disadvantages are that high-powered fans consume a lot of electricity, vehicle-mounted high-powered fans have a short operating time, and the presence of external wind can change the direction of the mist flow, affecting the effectiveness. Utility Model Content

[0005] The purpose of this utility model is to provide a filling and water replenishment device for earthwork roadbed construction. The spraying equipment is installed on the transport vehicle by means of a robotic arm, and the spraying position can be adjusted by the robotic arm, thereby effectively improving the water replenishment effect.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A filling and water replenishment device for earthwork roadbed construction includes a movable transport vehicle, a water storage tank mounted on the transport vehicle, a robotic arm, and a support structure connected to the robotic arm. The support structure includes a connecting frame, multiple parallel spray pipes arranged within the connecting frame, and multiple spray heads on each spray pipe. A main pipeline is provided on one side of the support structure, and each spray pipe is connected to the main pipeline. An on / off valve is provided at the connection between each spray pipe and the main pipeline. The main pipeline is connected to the water storage tank via a water delivery hose.

[0008] Furthermore, a switch ball valve is installed at the outlet of the water storage tank, and a booster pump is connected to the outlet of the switch ball valve.

[0009] Furthermore, the connecting frame includes at least two support rods, and multiple crossbars are provided between the two support rods, with multiple spray pipe through holes provided on the crossbars.

[0010] Furthermore, a gripping part is provided in the middle of one of the support rods, and the end of the robotic arm is clamped on the gripping part.

[0011] Furthermore, a bottom support structure is provided below the connecting frame. The bottom support structure includes a short balance bar located below a support bar with a grip, and a diagonal brace connecting the short balance bar and another support bar.

[0012] Furthermore, there are multiple balance bars, which are fixed at intervals below the support bar.

[0013] Compared with existing technologies, the advantages of this invention are: It has a simple structure and is easy to implement. By integrating a spray matrix on a vehicle-mounted platform, it can quickly replenish water to the roadbed, while also avoiding the problem of traditional fog cannons being easily affected by wind. Furthermore, it is applicable to various scenarios and has a flexible overall structure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] In the description of this utility model, it should be noted that if terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] Furthermore, the terms "first," "second," and "third" are used only for distinguishing descriptions and should not be interpreted as indicating or implying relative importance.

[0022] Furthermore, the use of terms such as "horizontal," "vertical," and "suspended" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0025] like Figure 1 As shown, a filling and water replenishment device for earthwork roadbed construction includes a movable transport vehicle 2, a water storage tank 1 installed on the transport vehicle 2, a mechanical arm 4, and a support structure 5 connected to the mechanical arm 4. The support structure 5 includes a connecting frame, multiple parallel spray pipes 7 installed in the connecting frame, and multiple spray heads installed on each spray pipe 7. A main pipeline 8 is installed on one side of the support structure. Each spray pipe 7 is connected to the main pipeline 8. An on / off valve is installed at the connection between each spray pipe 7 and the main pipeline 8. The main pipeline 8 is connected to the water storage tank 1 through a water delivery hose 3.

[0026] Compared to existing technologies, in traditional earthwork subgrade construction, water mist or fine water streams need to be sprayed onto the fill material (soil) during construction to bring its moisture content to or near the optimal compaction moisture content, thereby achieving the best compaction effect and subgrade quality. Traditional manual watering methods are inefficient and labor-intensive, leading to the development of mechanized equipment such as mist sprayers and water trucks to improve watering efficiency. However, traditional mist sprayers and similar equipment are greatly affected by the external environment, and their watering methods are prone to failure in windy or other weather conditions. In this invention, a spray matrix replaces the mist sprayer, resulting in a more stable spraying method. Furthermore, the density of the spray pipes can be adjusted according to specific needs, making the overall structure more flexible and reliable.

[0027] Specifically, in this invention, a ball valve is provided at the outlet of the water storage tank 1, and a booster pump is connected to the outlet of the ball valve. The ball valve controls the opening and closing of the output pipeline of the water storage tank 1, and the booster pump pressurizes the water for supply.

[0028] The connecting frame includes at least two support rods, and multiple crossbars 6 are arranged between the two support rods, with multiple spray pipe 7 through holes on the crossbars 6. One of the support rods has a gripping part in its middle, and the end of the robotic arm 4 is clamped onto the gripping part. The robotic arm 4 clamps the support rod to the gripping part for clamping operations. The gripping part needs to be a solid rod or plate to prevent deformation or breakage during clamping.

[0029] A bottom support structure is provided below the connecting frame. This structure includes a short balancing rod positioned below a support rod with a grip, and a diagonal brace connecting the short balancing rod and another support rod. Multiple short balancing rods are fixed at intervals below the support rods. The short balancing rods are primarily used to increase the weight on the gripping side when the connecting frame is too large. The diagonal brace connecting the short balancing rod to the support rod on the other side enhances overall stability, preventing the connecting frame from shifting due to gravity after the robotic arm 4 grips it, thus ensuring the spraying effect is achieved correctly.

[0030] In practical use, firstly, to reduce the overall weight of the connecting frame, the main rods of the connecting frame are hollow aluminum rods, while the gripping parts need to use solid cast iron rods or other similar solid metal rods. The hollow aluminum rods are connected sequentially by welding. The number of spray pipes 7 is designed according to the required water replenishment density, and corresponding through holes are made on the crossbar 6. The spray pipes 7 are passed through the crossbar 6 before the spray heads are installed, and finally the main pipeline 8 is installed, connecting the spray pipes 7 sequentially to the main pipeline 8. The main pipeline 8 is then connected to the booster pump through the water delivery hose 3. During the spraying operation, the robotic arm 4 is used to grab the connecting frame, and as the robotic arm 4 rotates, the connecting frame is placed above the water replenishment area. The on / off valve and booster pump are then opened to perform the water replenishment operation.

[0031] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
