[0036] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.
[0037] In actual line marking processes, due to harsh environments or when the road marking machine has not been used for a period of time, paint may accumulate in the paint supply components, affecting the spraying effect and leading to rework, thus affecting the final spraying efficiency.
[0038] Therefore, this application creatively proposes a marking device for construction, which includes a frame, wheel assembly, transmission gear set, material storage assembly, and mixing assembly. During road marking operations, when the drive wheel is driven by an external force to rotate, it not only moves the frame (i.e., the entire marking device) along the road surface but also drives the transmission shaft to rotate. This, in turn, drives the gear transmission assembly to operate as a whole through the gears connected to the transmission shaft. This ensures that the mixing shaft rotates continuously throughout the operation, guaranteeing that the paint in the material storage assembly remains uniformly mixed. Compared to existing technologies, this application effectively prevents the sedimentation of paint components, ensures stable spraying quality, reduces rework caused by uneven paint application, and significantly improves construction efficiency and operational accuracy.
[0039] The present application will be described in detail below through specific embodiments.
[0040] ReferenceFigures 1 to 5 As shown, the marking device includes a frame 1, a wheel assembly 2, a transmission gear set 3, a material storage assembly 4, and a mixing assembly 5. The wheel assembly 2 includes a drive shaft 21 and at least one drive wheel 22 rotatably connected to the frame 1. The drive shaft 21 is connected to the drive wheel 22, and the drive wheel 22 rotates under external force, thereby driving the drive shaft 21 to rotate and the frame 1 to move. At least one gear in the transmission gear set 3 is connected to the drive shaft 21, so that when the drive shaft 21 rotates, the gear connected to the drive shaft 21 drives the transmission gear set 3 to rotate. The material storage assembly 4 is mounted on the frame 1 and is used to store paint. The mixing assembly 5 has a mixing shaft 51 connected to the transmission gear set 3, and the mixing shaft 51 extends into the material storage assembly 4 to mix the paint under the drive of the transmission gear set 3.
[0041] In some examples, the frame 1 includes a base plate and various sheet metal structures connected to the base plate. The base plate serves as a basic platform to support the storage assembly 4 and other key components. The other sheet metal structures not only ensure a stable connection between the base plate and the wheel assembly 2, but also give the frame 1 sufficient strength and stability as a whole.
[0042] It is understandable that the number of drive wheels 22 can be two, three, or more, and the specific number needs to be flexibly set according to the load of the frame 1 and the overall operation of the marking device. In this embodiment, there are two drive wheels 22, and for the stability of the frame 1 when moving, the two drive wheels 22 can be respectively set at both ends of the drive shaft 21 axially; of course, when using an even number of drive wheels 22, these drive wheels 22 can be evenly divided into two groups, with each group of drive wheels 22 located at both ends of the drive shaft 21 axially. This layout not only helps to maintain the balance of the frame 1, but also improves the stability and reliability of the entire device during operation, thereby ensuring the safety and efficiency of the construction process.
[0043] In addition, in some examples, to further improve the stability of the frame 1 when stationary and the smoothness of the frame 1 when moving, the wheel assembly 2 also includes at least two auxiliary wheels, which are mounted on the side of the frame 1 away from the drive wheel 22, to help to support and move the frame 1 more evenly.
[0044] The auxiliary wheels and drive wheels 22 can be of the same type or different types depending on specific needs. For example, the auxiliary wheels can be equipped with a locking structure 81 to ensure the stability of the frame 1 when stationary; while the drive wheels 22 can have steering capabilities to allow operators to maneuver the marking device flexibly. This flexible design allows users to select the most suitable wheel combination based on the actual application scenario, thereby optimizing equipment performance and ensuring safety and efficiency in the construction process.
[0045] Specifically, during road marking operations, when the drive wheel 22 is driven to rotate by an external force, it not only moves the frame 1 (i.e., the entire marking device) along the road surface but also drives the drive shaft 21 to rotate. This, in turn, drives the gear transmission assembly to operate as a whole through the gears connected to the drive shaft 21. This ensures that the mixing shaft 51 rotates continuously throughout the operation, guaranteeing that the paint in the storage assembly 4 remains uniformly mixed. Compared to existing technologies, this application effectively prevents the sedimentation of paint components, ensures stable spraying quality, reduces rework caused by uneven paint application, and significantly improves construction efficiency and operational accuracy.
[0046] In some examples, refer to Figure 2 , Figure 2 and Figure 4 As shown, the storage assembly 4 includes a housing 41 and a first cavity 42 disposed within the housing 41. The first cavity 42 is used to store paint. The side of the housing 41 facing the drive shaft 21 has an opening 411. The gear connected to the drive shaft 21 extends into the housing 41 through the opening 411, and the remaining gears of the drive gear set 3 are located inside the housing 41 and outside the first cavity 42. The first cavity 42 has a passage hole (not shown in the figure), and the stirring shaft 51 extends into the first cavity 42 through the passage hole.
[0047] In this embodiment, the housing 41 is rectangular, but this is not the only option. Depending on the specific application scenario, the housing 41 can also be designed as a regular three-dimensional shape such as a cube or cylinder, or even an irregular shape to meet specific functional requirements. Regardless of the shape chosen, the key is to ensure that the housing 41 has sufficient internal space to accommodate the paint and the main body of the transmission gear set 3, and has sufficient structural strength to ensure the stability and durability of the equipment.
[0048] In some examples, the top of the housing 41 has an opening 411 and a cover plate over the opening 411 to facilitate the handling of the first cavity 42 and other components inside the housing 41 by the staff.
[0049] In some examples, bearings can be installed at the opening 411 and / or the passage hole to improve the stability of the rotation of the stirring shaft 51, and sealing structures such as sealing rings can be installed in the corresponding positions to prevent paint leakage.
[0050] Specifically, by placing the main body of the transmission gear set 3 inside the housing 41, the wear of the gears by dust, stones, and other debris in the external environment can be reduced, ensuring the stability of the operation of the transmission gear set 3, thereby ensuring that the stirring shaft 51 connected to the transmission gear set 3 can stably stir the coating. The first cavity 42, which stores the coating separately, facilitates the individual processing of the coating inside by the staff.
[0051] In some examples, the first cavity 42 is detachably connected to the housing 41, and a guide structure is provided between the first cavity 42 and the housing 41.
[0052] See, as an example rather than a limitation. Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the housing 41 is provided with a support strip 412, which is used to support the first cavity 42. The guide structure includes a guide strip 413 located on the inner side of the housing 41 and a guide groove 421 located on the outer side of the first cavity 42. The guide strip 413 and the guide groove 421 are slidably engaged.
[0053] In order to improve the stability of the support strip 412 for the first cavity 42, the support strip 412 can be arranged around the circumference of the box 41.
[0054] In addition, the first cavity 42 and the box 41 can also be connected by plug-in, threaded connection or other methods. Regardless of the method chosen, the key is to ensure the stability of the connection between the first cavity 42 and the box 41 and the ease of disassembly.
[0055] In some examples, one end of the first cavity 42 is open 411 and has a cover plate that seals the opening 411 so that paint can be quickly injected into the first cavity 42 by opening the cover plate.
[0056] In some examples, a second or third cavity may also be provided inside the housing 41 to store some tools needed for road marking operations.
[0057] Specifically, in actual use, users can equip a single marking device with multiple first cavities 42, each containing different types of paint. When performing road marking operations, users can select the corresponding first cavity 42 according to the marking requirements of the current road section, and then remove the original first cavity 42. This eliminates the need to prepare multiple marking devices or frequently clean the first cavity 42. Simple disassembly and replacement can achieve rapid conversion, greatly improving work efficiency and flexibility.
[0058] It is understandable that the transmission gear set 3 can contain two, three, or more gears, and the types of gears can be spur gears, helical gears, or bevel gears, etc. The specific number and type of gears need to be determined based on the internal size of the housing 41 and the actual transmission requirements.
[0059] See, as an example rather than a limitation. Figure 2 As shown, the transmission gear set 3 includes a first gear 31 and a second gear 32 that mesh with each other. The first gear 31 is connected to the transmission shaft 21, and the second gear 32 is connected to the stirring shaft 51. It should be noted that... Figure 2The gears shown are for illustrative purposes only and do not represent the actual size of the gears.
[0060] For example, the transmission can be achieved through two meshing spur gears, one of which is connected to the drive shaft 21. In this case, a passage hole is formed on the side of the first cavity 42 so that the stirring shaft 51, connected to the spur gear, can extend into the first cavity 42 for stirring. It is understood that the transmission gear set 3 can also contain three or more spur gears, as long as the stirring shaft 51 is connected to the last output spur gear.
[0061] In this embodiment, the gear and shaft are generally connected by a key. Of course, interference fit, pin connection, and other connection methods can also be used. The key is to meet the connection strength requirements between the gear and shaft to ensure the stability of the device operation.
[0062] In this embodiment, refer to Figure 2 As shown, both the first gear 31 and the second gear 32 are bevel gears. Through these two meshing bevel gears, the transmission system (mainly referring to the transmission gear set 3) can convert the horizontal rotational motion into the vertical rotational motion. This allows the stirring shaft 51 to rotate along an axis perpendicular to the ground, thereby allowing the first cavity 42 to extend vertically, which improves the compactness of the marking device.
[0063] In some examples, the transmission ratio between the first gear 31 and the second gear 32 is 1:10 to 1:3. This makes the final output speed of the transmission gear set 3 three to ten times the input speed. Specifically, when the transmission shaft 21 rotates one revolution, the first gear 31 rotates one revolution, thereby driving the second gear 32 to rotate three to ten revolutions, and finally driving the stirring shaft 51 to rotate three to ten revolutions. This transmission ratio design not only ensures that the paint components in the first cavity 42 can always be mixed evenly, but also avoids the impact of excessive stirring on the delivery of paint to the spray gun 7, ensuring smooth spraying and high-quality completion.
[0064] In some examples, refer to Figure 3 As shown, the marking device also includes an auxiliary container 6 and at least two spray guns 7 mounted on the frame 1. The auxiliary container 6 is used to store paint, and the storage assembly 4 and the auxiliary container 6 are respectively connected to at least one spray gun 7.
[0065] It is understandable that when marking road surfaces, the actual type of paint required (such as different colors) is often more than one. To meet this need, this application adds at least one auxiliary container 6 and a corresponding spray gun 7 to achieve the dispensing and application of multi-color paints. Specifically, the first chamber 42 is mainly used to store the primary paint, while the smaller auxiliary container 6 is used to dispense other colors of paint. Users can flexibly select and activate the corresponding spray gun 7 according to actual marking needs, thereby achieving accurate spraying of multiple colors without frequent equipment changes or cleaning of paint containers (mainly referring to the first chamber 42).
[0066] Furthermore, in some examples, refer to 3 and Figure 5 As shown, the marking device also includes a mounting bracket 8 mounted on the vehicle frame 1. The spray gun 7 is slidably mounted on the mounting bracket 8, and the mounting bracket 8 is also provided with a locking structure 81 for fixing the spray gun. During road marking operations, due to limitations of the construction site environment or the actual spraying position, it is usually necessary to adjust the position of one or more spray guns 7 in the horizontal direction. Specifically, in this embodiment, the mounting bracket 8 includes a main board 83 with a dovetail groove 831 and a mounting plate 84 for fixing the spray gun 7. The mounting plate 84 slides with the dovetail groove 831 on the main board 83 via a dovetail slider 841, allowing the spray gun 7 to be flexibly adjusted in the horizontal direction. A strip groove 832 communicating with the dovetail groove 831 is provided on the side of the main board 83 away from the spray gun 7. A threaded hole 8411 is provided on the dovetail slider 841. By using a bolt passing through the strip groove 832 and extending into the threaded hole 8411 of the dovetail slider 841, the user can easily adjust the position of the spray gun 7. Generally, once the spray gun 7 is moved to the desired target position, simply tightening the bolts to make it abut against the main board 83 will lock the spray gun 7, ensuring its stability during operation.
[0067] Furthermore, in some examples, refer to Figure 3 As shown, the frame 1 is also equipped with a column 82 arranged along its height direction, and the mounting bracket 8 is slidably engaged with the column 82. Specifically, in this embodiment, the main board 83 is slidably connected to the column 82 via a slider, which allows the user to flexibly adjust the position of the spray gun 7 relative to the road surface to be marked before performing road marking operations, according to the actual spraying height requirements. By adjusting the height of the spray gun 7, the user can ensure that the spray gun 7 is always kept at the most suitable working height, thereby ensuring the accuracy and quality of the marking.
[0068] In some examples, refer to Figure 2As shown, the stirring assembly 5 also includes a stirring crossbar 52 detachably connected to the stirring shaft 51. Specifically, in this embodiment, the stirring shaft 51 is provided with multiple insertion holes. The user can flexibly increase or decrease the number of stirring crossbars 52 according to the actual liquid level of the coating in the first cavity 42 to fully stir all the coating in the first cavity 42 and ensure uniform mixing of the coating. The connection between the stirring crossbar 52 and the insertion holes can be a threaded connection, a plug-in connection, or other connection methods.
[0069] In some examples, refer to Figure 1 As shown, the marking device also includes a handle 9 connected to the frame 1. Users can push the handle 9 to rotate the drive wheel 22, thereby moving the entire marking device. This method meets the current practical needs of marking operations and, because it relies on manual power, has the advantage of being environmentally friendly. Furthermore, to meet the needs of different construction scenarios and improve work efficiency, the marking device can also be equipped with drive components such as motors to automatically rotate the drive wheel 22. This design provides flexible options: users can choose between manual or electric modes based on the specific working environment and requirements, ensuring both construction flexibility and improved work efficiency.
[0070] It should be noted that the marking device also includes necessary components such as an air compressor and a pump. These components fall within the scope of existing technology and are widely used in the industry, so their specific structure and function will not be described in detail here.
