Description

Technical Field

[0001] This disclosure relates to the field of manhole cover processing, and more specifically, to a painting device for manhole covers. Background Technology

[0002] Cast iron manhole covers are typically installed outdoors and exposed to corrosive environments such as humidity and acids / alkalis for extended periods (e.g., in manufacturing industrial parks). Therefore, rust prevention treatment is necessary to extend their service life. Currently, during the production of cast iron manhole covers, rust-preventive paint is usually applied by brushing or spraying. Spraying is generally done manually, which is time-consuming and inefficient. Furthermore, manual application is unpredictable, resulting in inconsistent thickness and quality of each coat, leading to uneven coating or omissions, thus affecting the quality of the manhole cover. Utility Model Content

[0003] The purpose of this disclosure is to provide a painting device for manhole covers to solve the quality problem caused by uneven coating when applying anti-rust paint to manhole covers.

[0004] To achieve the above objectives, this disclosure provides a painting device for manhole covers, comprising:

[0005] Base;

[0006] A turntable, rotatably mounted on the base, is used to hold a manhole cover;

[0007] A longitudinal moving mechanism is connected to the base; and

[0012] Optionally, the turntable further includes a plurality of positioning posts spaced apart on the upper surface of the placement plate for engaging with the manhole cover.

[0013] Optionally, the longitudinal movement mechanism includes:

[0014] A second drive unit is connected to the base; and

[0015] The first connecting block is connected to the paint brush head, and the first connecting block is connected to the output end of the second driving member. The second driving member can drive the first connecting block to move in the height direction.

[0016] Optionally, the second driving element includes:

[0017] The first guide rail is located on one side of the turntable, and one end of the first guide rail is connected to the base, while the other end extends away from the base along the height direction.

[0018] A first motor is connected to one end of the first guide rail; and

[0019] A first screw is connected to the output end of the first motor and extends along the height direction. The first motor can drive the first screw to rotate. The first screw and the first guide rail are respectively mounted on the first connecting block. The first connecting block is provided with a first threaded hole that mates with the first screw, so that when the first screw rotates, it drives the first connecting block to move linearly along the extension direction of the first guide rail.

[0020] Optionally, the paint brush head includes:

[0021] The brush handle has one end connected to the longitudinal moving mechanism and the other end extending horizontally away from the longitudinal moving mechanism; and

[0022] Multiple clumps of bristles are arranged sequentially on the lower surface of the brush handle along its extension direction for contact with the manhole cover.

[0023] Optionally, the painting section further includes:

[0024] The third drive component is connected to the longitudinal moving mechanism and is disposed adjacent to the paint brush head; and

[0025] The second connecting block is connected to the paint can and is connected to the output end of the third driving member. The third driving member can drive the second connecting block to move in the horizontal direction, so that the second connecting block can sequentially contact the multiple clusters of bristles to adhere the paint to the multiple clusters of bristles.

[0026] Optionally, the third driving element includes:

[0027] The second guide rail has one end connected to the longitudinal moving mechanism and the other end extending horizontally away from the longitudinal moving mechanism.

[0028] The second motor is connected to one end of the second guide rail; and

[0029] The second screw is connected to the output end of the second motor and extends horizontally. The second motor can drive the second screw to rotate.

[0030] Optionally, one end of the second connecting block is further formed with a concave block for covering the outside of the bristles, wherein the bottom of the concave block is disposed opposite to the end of the bristles away from the brush handle, and the bottom of the concave block is in communication with the paint can.

[0031] Optionally, the paint can is mounted on the base, and the painting section further includes a paint pump and paint pipes connected at both ends to the paint brush head and the paint pump, respectively. The paint pump is mounted on the paint can and is used to transport the paint in the paint can to the paint brush head through the paint pipes.

[0032] Through the above technical solution, the painting device uses the rotation of the turntable to drive the manhole cover to rotate, enabling the paint to be evenly applied to the surface of the manhole cover. This not only effectively improves the uniformity of the paint application but also increases painting efficiency, reduces paint waste, and lowers production costs. Furthermore, the longitudinal movement mechanism controls the up-and-down movement of the painting unit, facilitating manhole cover replacement and preventing excess paint from adhering to the manhole cover during replacement. This ensures a uniform coating and avoids uneven coating conditions.

Detailed Implementation

[0039] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0040] In this disclosure, unless otherwise stated, directional terms such as "upper" and "lower" are defined in relation to the actual arrangement direction of the painting device used for manhole covers, and directional terms such as "inner" and "outer" are defined in relation to the outline of the corresponding components. The terms "first," "second," etc., are used to distinguish different components and do not imply sequentiality or importance. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements.

[0041] According to one embodiment of this disclosure, such as Figure 1 and Figure 2 As shown, a painting device for manhole covers is provided, including a base 1, a turntable 2, a longitudinal moving mechanism 3, and a painting section 4. The turntable 2 is rotatably mounted on the base 1 for holding the manhole cover. The longitudinal moving mechanism 3 is connected to the base 1, and the painting section 4 can be connected to the longitudinal moving mechanism 3. The longitudinal moving mechanism 3 can drive the painting section 4 to move closer to or further away from the turntable 2 in the height direction. The painting section 4 includes a brush head 41 and a paint can 42 for holding paint, used to move the paint in the paint can 42 onto the manhole cover via the brush head 41.

[0042] Through the above technical solution, the painting device, by rotating the turntable 2 and driving the manhole cover to rotate, enables the paint to be evenly applied to the surface of the manhole cover. This not only effectively improves the uniformity of the paint application but also increases painting efficiency, reduces paint waste, and lowers production costs. Furthermore, by controlling the up-and-down movement of the painting unit 4 through the longitudinal movement mechanism 3, it not only facilitates manhole cover replacement but also prevents excess paint from adhering to the manhole cover during replacement, thus ensuring a uniform coating and avoiding uneven coating conditions.

[0043] It should be noted that the painting device can be used for painting both ordinary cast iron manhole covers and ductile iron manhole covers; this disclosure makes no limitation in this regard. Furthermore, the painting device described in this disclosure can be used in the manufacturing process of parts requiring paint coating, such as the painting of pedals and some relatively smooth interior trim parts in automobiles; this disclosure makes no limitation in this regard. As for paint used on automobile parts, appropriate paint residue can be used to paint manhole covers within factory premises, thus saving on manhole cover painting costs.

[0044] Furthermore, such as Figure 1 As shown, the turntable 2 may include a placement plate 21 and a first driving component 22. The placement plate 21 is used to place the manhole cover, and the first driving component 22 can be mounted on the base 1, with its output end connected to the placement plate 21, enabling it to drive the placement plate 21 to rotate. The first driving component 22 can be an electric motor or a hydraulic motor; this disclosure does not limit its use. Driving the placement plate 21 to rotate via the first driving component 22 controls its rotational speed, ensuring the manhole cover rotates evenly during the painting process. This ensures the paint covers every corner of the manhole cover, preventing uneven or missed areas. This not only improves the uniformity of the paint application but also automates and increases the efficiency of the entire painting process, replacing manual application of anti-rust paint, significantly improving work efficiency, reducing labor costs, and minimizing workers' direct contact with paint, thus reducing the threat of harmful substances to workers' health and improving the working environment. The rotational speed of the first driving component 22 can be adjusted as needed, allowing control of the placement plate 21's rotational speed according to the painting requirements of different manhole covers, further enhancing the flexibility and practicality of the device.

[0045] Furthermore, such as Figure 1 As shown, the turntable 2 may also include multiple positioning posts 23 spaced apart on the upper surface of the placement plate 21 for engaging with the manhole cover. Specifically, the manhole cover may have grooves or recesses corresponding to the positioning posts 23. The engagement of the manhole cover with the positioning posts 23 reduces the probability of the manhole cover shifting during painting, ensuring stability during rotation, thereby improving the accuracy and uniformity of the painting process and reducing uneven or missed painting caused by manhole cover movement. The positioning posts 23 may also be detachable or movable. By adjusting the position and number of the positioning posts 23, they can be adapted to manhole covers of different sizes and shapes, thus increasing the flexibility and applicability of the painting device.

[0046] According to one embodiment of this disclosure, such as Figure 2As shown, the longitudinal moving mechanism 3 may include a second driving member 31 and a first connecting block 32. The second driving member 31 can be connected to the base 1, and the paint brush head 41 is connected to the first connecting block 32. The first connecting block 32 is connected to the output end of the second driving member 31, and the second driving member 31 can drive the first connecting block 32 to move in the vertical direction. By adjusting the position of the first connecting block 32 through the second driving member 31, the position of the paint brush head 41 is adjusted, making the position of the paint brush head 41 more precise each time it stops above the manhole cover, thus ensuring uniform painting among multiple manhole covers. By precisely controlling the height of the paint brush head 41, it can adapt to manhole covers of different thicknesses, improving the applicability of the device.

[0047] Regarding the structure of the second driving component 31, the second driving component 31 can be a hydraulic cylinder, pneumatic cylinder, or similar structure. A reciprocating piston rod is installed inside the cylinder, and the movement of the piston rod drives the first connecting block 32 to move. The second driving component 31 may also include a first guide rail 311, a first motor 312, and a first screw 313. Figure 1 As shown, the first guide rail 311 can be located on one side of the turntable 2, with one end of the first guide rail 311 connected to the base 1 and the other end extending away from the base 1 along the height direction. The first motor 312 can be connected to one end of the first guide rail 311, and the first screw 313 can be connected to the output end of the first motor 312 and extends along the height direction. The first motor 312 can drive the first screw 313 to rotate. The first screw 313 and the first guide rail 311 are respectively mounted on the first connecting block 32, and the first connecting block 32 is provided with a first threaded hole that mates with the first screw 313, so that when the first screw 313 rotates, it drives the first connecting block 32 to move linearly along the extension direction of the first guide rail 311. Regarding the method of supplying paint to the paint brush head 41 in the painting section 4, a structure in which the motor drives the screw and the guide rail to supply paint to the paint brush head 41 can also be used, which will be described in detail below.

[0048] It should be noted that, as Figure 1 and Figure 2As shown, the paint brush head 41 may include a brush handle 411 and multiple tufts of bristles 412. One end of the brush handle 411 is connected to the longitudinal moving mechanism 3, and the other end extends horizontally away from the longitudinal moving mechanism 3. The multiple tufts of bristles 412 may be disposed on the lower surface of the brush handle 411 and may be arranged sequentially along the extending direction of the brush handle 411 for contact with the manhole cover. By adhering paint to the bristles 412, and by adjusting the position of the longitudinal moving mechanism 3, the bristles 412 are made to evenly contact the surface of the manhole cover, ensuring that the paint is evenly coated. The length of the brush handle 411 can be set according to actual needs, and the connection between the brush handle 411 and the longitudinal moving mechanism 3 may be designed as a detachable structure to facilitate compatibility with manhole covers of various sizes; this disclosure does not limit this. Alternatively, the paint brush head 41 may also be a spray head connected to the longitudinal moving mechanism 3, which rotates the turntable 2 to drive the manhole cover to rotate, thereby allowing the spray head to spray paint onto different positions of the manhole cover to complete the coating; this disclosure also does not limit this.

[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the painting unit 4 may further include a third driving member 43 and a second connecting block 44. The third driving member 43 may be connected to the longitudinal moving mechanism 3 and is disposed adjacent to the painting head 41. The paint tank 42 may communicate with the second connecting block 44, which is connected to the output end of the third driving member 43. The third driving member 43 can drive the second connecting block 44 to move horizontally, so that the second connecting block 44 can sequentially contact the multiple clumps of brush bristles 412 to adhere the paint to the multiple clumps of brush bristles 412. The third driving member 43 controls the movement of the second connecting block 44 and can adjust the position of the second connecting block 44 so that the paint in the paint tank 42 can be evenly distributed on the brush bristles 412 through the second connecting block 44, ensuring that each clump of brush bristles 412 can be evenly coated with paint, avoiding uneven painting or missed painting caused by uneven paint distribution, and further improving the uniformity and quality of painting.

[0050] Here, the second connecting block 44 can directly contact one side of the brush bristles 412, or it can cover the outside of the brush bristles 412. Specifically, one end of the second connecting block 44 can be formed with a concave block 441 for covering the outside of the brush bristles 412. The bottom of the concave block 441 can be positioned opposite to the end of the brush bristles 412 away from the brush handle 411, and the bottom of the concave block 441 is connected to the paint can 42. In this way, the paint can flow out from the bottom of the concave block 441 and directly adhere to the end of the brush bristles 412, ensuring that each clump of brush bristles 412 can be coated with paint when the second connecting block 44 moves, thereby reducing the occurrence of missed coating. In addition, by covering the concave block 441, when a large amount of paint overflows from the bottom of the concave block 441, the side wall of the concave block 441 can also prevent the paint from spreading. This not only reduces paint waste and lowers production costs, but also allows the paint to adhere to the side wall of the concave block 441. Thus, as the second connecting block 44 moves, the paint adhering to the side wall of the concave block 441 can also adhere to the middle part of the bristles 412, increasing the paint adhesion rate of the bristles 412 and further reducing the possibility of missed coating.

[0051] Regarding the structure of the third driving component 43, it can also be a hydraulic cylinder, pneumatic cylinder, or similar structure mentioned above. A reciprocating piston rod is installed inside the cylinder, and the movement of the piston rod drives the second connecting block 44 to move. The third driving component 43 can also include a second guide rail 431, a second motor 432, and a second screw 433. For example... Figure 1 As shown, one end of the second guide rail 431 can be connected to the longitudinal moving mechanism 3, and the other end extends horizontally away from the longitudinal moving mechanism 3. The second motor 432 can be connected to one end of the second guide rail 431, and the second screw 433 can be connected to the output end of the second motor 432 and extends horizontally. The second motor 432 can drive the second screw 433 to rotate. The second screw 433 and the second guide rail 431 are respectively mounted on the second connecting block 44, and the second connecting block 44 is provided with a second threaded hole that mates with the second screw 433. This allows the second connecting block 44 to move linearly along the extension direction of the second guide rail 431 when the second screw 433 rotates. This disclosure does not limit this aspect.

[0052] Regarding the placement of the paint can 42, it can be mounted on the brush head 41 and move with the brush head 41, or it can be mounted on the base 1. This allows the paint can 42 to store more paint, reducing the frequency of refills, and eliminates the need to consider the impact of the paint can 42's weight on the brush head 41. Figure 1 and Figure 2As shown, the painting unit 4 may also include a paint pump 45 and a paint pipe 46 connected at both ends to the paint brush head 41 and the paint pump 45 respectively. The paint pump 45 may be installed on the paint tank 42 and is used to transport the paint in the paint tank 42 to the paint brush head 41 through the paint pipe 46. By adjusting the pumping rate of the paint pump 45, the paint can be stably supplied to the paint brush head 41, improving the paint conveying efficiency, ensuring the continuity and stability of the painting process, and making the paint supply more precise and controllable.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.
