Description

Technical Field

[0001] The utility model particularly relates to an automatic spraying device for anti-collision guardrails, belonging to the technical field of municipal engineering equipment. Background Art

[0002] The spray painting of the surface of the guardrail is an important method to protect the metal surface from oxidation and corrosion. The outdoor guardrail is in a relatively complex external natural environment, which is prone to bubbling, cracking, and falling off. A good spray painting can not only beautify the guardrail, but also extend its service life. Therefore, it is particularly important to quickly and efficiently perform anti-rust maintenance on the railing.

[0003] is important.

[0004] At present, the anti-rust maintenance of outdoor continuous or segmental guardrails mainly adopts manual painting, which has a large amount of work and a long period. It usually requires multiple workers to paint in sections at the same time. The labor intensity is high, the efficiency is low, and the painting quality is uneven. In addition, the paint contains a large amount of benzene (benzene, toluene, xylene) and other substances that are harmful to human health. Long-term exposure to this working environment will affect the health of the painters.

[0005] Nowadays, the spray painting equipment for outdoor protective railings on the market can only achieve short-distance intermittent spray painting. Most of the equipment has a low degree of automation and the paint quality is not high. It cannot achieve long-distance uninterrupted continuous spray painting. Moreover, most spray painting equipment does not pay attention to the recycling and reuse of overspray paint, resulting in a lot of paint waste, serious pollution, and a lack of energy-saving and environmental protection awareness.

[0043] Example

[0044] See also Figure 1-Figure 9 , structures such as pipelines and lines are omitted in the figure. An automatic spraying equipment for an anti-collision guardrail includes a mobile attachment bracket 100, a spraying device and a driving assembly (not shown in the figure). The mobile attachment bracket 100 can be attached to the anti-collision guardrail by clamping / hanging. The driving assembly is installed on the mobile attachment bracket 100 and is mainly used to drive the mobile attachment bracket 100 to move along the anti-collision guardrail. The spraying device is installed on the mobile attachment bracket 100 and is mainly used to spray paint on the anti-collision guardrail.

[0045] Specifically, the mobile attachment bracket 100 includes a support frame 110 and a first roller group 121 and a second roller group 122. The support frame 110 has a limiting structure, which can cooperate with the anti-collision guardrail by clamping / hanging, so that the support frame 110 as a whole can be attached / set on the anti-collision guardrail, the first roller group 121 and the second roller group 122 are both installed on the support frame 110, and the first roller group 121 and the second roller group 122 are both located in the limiting structure. The roller groups 122 are arranged opposite to each other and at intervals along a first direction. When a part of the anti-collision guardrail is arranged in the limiting structure, the first roller group 121 and the second roller group 122 are respectively arranged on both sides of the anti-collision guardrail along the first direction and roll with the anti-collision guardrail; at least one of the first roller group 121 and the second roller group 122 is transmission-connected to the drive assembly, and can roll along the anti-collision guardrail around its own axis under the drive of the drive assembly, so that the mobile attachment bracket 100 and the anti-collision guardrail can walk / translate along the anti-collision guardrail.

[0046] It can be understood that when the mobile attachment bracket 100 is attached to the anti-collision guardrail, the first roller group 121 and the second roller group 122 can respectively roll in contact with the first side and the second side of the clamped anti-collision guardrail, and the first side and the second side are arranged relatively along the first direction.

[0047] More specifically, the limiting structure may be a semi-open limiting space enclosed by a part of the support frame 110. More specifically, the first roller group 121 and the second roller group 122 each include at least one rollable roller 101. The specific assembly structure of the roller 101 and the support frame 110 is not specifically limited here. It can be implemented in any suitable manner known in the art. The multiple rollers can be respectively driven by the drive assembly and can roll independently. Of course, the multiple rollers can also realize motion transmission through transmission structures such as gears and transmission shafts, that is, a part of the multiple rollers can move synchronously. It can be understood that the rollers connected to the drive assembly are driving wheels, and those rollers that are not connected to the drive assembly but can rotate around their own axes are driven wheels.

[0048] Specifically, the support frame 110 includes a first support mechanism 111, a second support mechanism 112 and a third support mechanism 113 that are fixedly connected. The first support mechanism 111 and the second support mechanism 112 are spaced apart and relatively arranged along the first direction. The first support mechanism 111 and the second support mechanism 112 are located on the same side of the third support mechanism 113. The limiting structure is formed between the first support mechanism 111 and the second support mechanism 112, that is, the limiting structure is a semi-open limiting space enclosed by the first support mechanism 111, the second support mechanism 112 and the third support mechanism 113, and the first roller group 121 and the second roller group 122 are respectively installed on the first support mechanism 111 and the second support mechanism 112.

[0049] Specifically, in the second direction, the length of the first supporting mechanism 111 is less than the length of the second supporting mechanism 112, and the driving assembly and the spraying device are installed on the second supporting mechanism 112, or the driving assembly and the spraying device are installed on the second supporting mechanism 112 and the third supporting mechanism 113; it should be noted that the first roller group 121 and the second roller group 122 are not only used to realize the support frame 110 walking along the anti-collision guardrail, but also the first roller group 121 and the second roller group 122 are directly in contact with the anti-collision guardrail. The second roller group 122 is located between the support frame 110 and the anti-collision guardrail, and also plays a certain supporting role for the support frame 110, and improves the structural stability of the support frame 110 on the anti-collision guardrail. Based on this, the number of rollers included in the second roller group 122 located on the second support mechanism 112 with a longer length is preferably set to be larger, and the multiple rollers included in the second roller group 122 are preferably set at the four corners and the middle area of ​​the second support mechanism 112, and the multiple rollers included in the first roller group 121 are preferably set at the four corners and the middle area of ​​the first support mechanism 111. Of course, when the length / area of ​​the first support mechanism 111 is small, and the first roller group 121 can achieve its own structural stability by using only a few rollers, the multiple rollers 101 included in the first roller group 121 can also be set only in the middle area of ​​the first support mechanism 111.

[0050] Specifically, in order to improve the smoothness of the movement of the mobile attachment bracket 100 on the anti-collision guardrail, a third roller group 123 is also installed on the side of the third support mechanism 113 facing the limiting structure. The rollers included in the third roller group 123 are used to roll with the top end surface of the anti-collision guardrail. It can be understood that the support frame 110 does not directly contact the anti-collision guardrail. More specifically, the third roller group 123 can be connected to the drive assembly and can roll directly under the drive of the drive assembly. Of course, the rollers included in the third roller group 123 can also be used as driven wheels.

[0051] Specifically, the drive assembly may include at least one servo motor, which is connected to at least one roller in the first roller group 121, the second roller group 122, and the third roller group 123 through at least one transmission structure such as a transmission shaft, a gear, a belt, etc. The servo motor can be fixedly assembled on the support frame 110 through a fixed frame, and its specific assembly structure is defined here.

[0052] Specifically, the spraying device includes a coating supply mechanism 220 and a plurality of spray guns 210, wherein the plurality of spray guns 210 are fixed on the support frame 110 and are sequentially spaced along the second direction, and the plurality of spray guns 210 are also connected to the coating supply mechanism 220 via a feed pipeline, and the coating supply mechanism 220 can be arranged on the top of the support frame 110, and can be arranged on the top of the second support mechanism 112 and / or the third support mechanism 113, and more specifically, a feed pump and the like are also arranged on the feed pipeline between the coating supply mechanism and the plurality of spray guns 210. More specifically, the coating supply mechanism 220 can be a coating tank and the like. It should be noted that, of course, a switch valve and the like can also be arranged on the feed pipeline between the coating supply mechanism and the plurality of spray guns 210, and the coating supply mechanism, the plurality of spray guns 210, the switch valve and the like are all known in the art and can all be purchased commercially.

[0053] Specifically, in the second direction, the plurality of spray guns 210 are arranged at equal intervals, and the intervals between the plurality of spray guns 210 are determined according to the coverage of the spraying area of ​​each spray gun 210, so that the sprayed paint etc. can be evenly coated on the anti-collision guardrail.

[0054] Specifically, in order to prevent the movable attachment bracket 100 from moving along the anti-collision guardrail and affecting the coating formed by spraying, it is preferred to arrange a plurality of spray guns 210 on one side of the second roller group 122 along the moving direction of the movable attachment bracket 100 .

[0055] For details, please refer to Figure 3 , Figure 5 and Figure 7A spray protection mesh cover 300 is also fixedly installed on the second supporting mechanism 112, and the spray protection mesh cover has a spray operation port, and the spray operation port faces the confined space, wherein the multiple spray guns 210 are located in the spray protection mesh cover, and the working ends of the spray guns 210 point to the spray operation port. More specifically, the spray protection mesh cover 300 can also extend and surround the periphery of the confined space set on the supporting frame 110. By setting up the spray protection mesh cover 300, the spraying operation space and the external environment can be isolated to a certain extent. In terms of construction quality, during the spraying operation, the spray protection mesh cover reduces the influence of wind on the paint mist sprayed from the spray gun in the spraying operation space, so that the paint mist sprayed from the spray gun can maintain its inherent shape as a whole (for example, it can be a complete fan-shaped surface. Of course, the overall shape of the paint mist sprayed from the spray gun is determined by the structure of the nozzle of the spray gun), and the uniformity of the formed paint film (mainly the thickness uniformity) is better; in terms of safety and environmental protection, most of the excess paint mist in the spraying operation space will adhere to the spray protection mesh cover, which greatly reduces the impact of the spraying operation on the surrounding environment and surrounding buildings and people. At the same time, the spray protection mesh cover is detachable, so that the spray protection mesh cover can be cleaned and / or replaced separately to ensure better work efficiency.

[0056] Specifically, the spray protection mesh cover may include an outer shell, which is fixedly connected to the second support mechanism 112. However, it should be noted that when the second support mechanism 112 is a non-hollow frame structure but a planar structure, the spray protection mesh cover may also be formed by the outer shell and the second support mechanism 112 being fixedly connected and jointly enclosed.

[0057] Furthermore, the outer shell includes a plurality of independent porous plates, on which are distributed a plurality of micrometer-scale through holes, the aperture of the through holes being 0.1 mm-2 mm, and each of the porous plates is independently and detachably mounted on the second supporting mechanism 112. Exemplarily, the porous plates can be detachably mounted on the second supporting mechanism 112 by snap-fit ​​connection, mortise and tenon connection, magnetic adsorption, and with the aid of accessories such as bolts. The porous plates are detachably arranged, and each porous plate can be disassembled individually for subsequent maintenance work such as cleaning.

[0058] Specifically, the anti-collision guardrail automatic spraying equipment may also include a controller, an operation panel, and a power supply, etc. The controller, the operation panel, and the power supply are installed on the support frame 110, and the controller is electrically connected to the spray device, the drive assembly, and the operation panel. The operating parameters of the spray device and the drive assembly can be adjusted through the operation panel. The controller, the operation panel, the drive assembly, the spray device, etc. are also electrically connected to the power supply. It should be noted that the controller, the operation panel, and the specific methods for adjusting the working parameters of the spray device and the drive assembly through the operation panel are all known in the art and are not limited here.

[0059] An automatic spraying device for anti-collision guardrails provided by an embodiment of the utility model has a simple structure and is more convenient to operate and use. The automatic spraying device for anti-collision guardrails can be attached to the anti-collision guardrails and move along the anti-collision guardrails. At the same time, the spraying operation of the anti-collision guardrails can be realized during the walking process, and by making multiple spray guns spray at equal intervals in the height direction of the anti-collision guardrails, the uniformity of the spraying can be ensured; the overall movement of the equipment is achieved through the built-in drive assembly, which not only improves the operating efficiency, but also reduces the labor intensity of the operator and the cost of the spraying operation.

[0060] It should be understood that the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
