[0033] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0034] Please refer to the reference. Figures 1 to 6 This utility model embodiment provides a guardrail cleaning vehicle (not shown) for rapid cleaning of urban guardrails. It can achieve emergency release in the event of a collision to prevent damage to the drive mechanism 140, thereby improving safety and extending the service life of the drive mechanism 140.

[0035] It should be noted that the guardrail cleaning vehicle includes a vehicle body (not shown in the figure) and a safety cleaning device 100. The safety cleaning device 100 is installed on the vehicle body, and the vehicle body is used to drive the safety cleaning device 100 to move along the extension direction of the guardrail. The safety cleaning device 100 is used to perform roller brush cleaning on the guardrail during the movement.

[0036] The safety cleaning device 100 includes a telescopic arm 110, a first roller brush mechanism 120, a second roller brush mechanism 130, a drive mechanism 140, a first toothed ring 150, a second toothed ring 160, and a rotating seat 170. The telescopic arm 110 is cylindrical and includes a fixed section 111 and a telescopic section 112 that can extend or retract relative to the fixed section 111. The first roller brush mechanism 120 is mounted on the fixed section 111, which fixes its position. The drive mechanism 140 is mounted on the telescopic section 112 and connected to the first toothed ring 150. The first toothed ring 150 and the second toothed ring 160 cooperate and are rotatably fitted outside the telescopic section 112. The second toothed ring 160 is connected to the rotating seat 170. The second roller brush mechanism 130 is mounted on the rotating seat 170, which is rotatably fitted outside the telescopic section 112. The telescopic section 112 can synchronously drive the drive mechanism 140, the first toothed ring 150, the second toothed ring 160, and the rotating seat 170 to move along the axial direction of the telescopic section 112, thereby driving the second roller brush mechanism 130 away from or closer to the first roller brush mechanism 120. The drive mechanism 140 can drive the rotating seat 170 to rotate through the cooperation of the first toothed ring 150 and the second toothed ring 160, thereby driving the second roller brush mechanism 130 to rotate, so as to flexibly adjust the position of the second roller brush mechanism 130, thus facilitating the cleaning of the guardrail. During this process, the telescopic section 112 can limit the rotating seat 170 so that the rotating seat 170 can only rotate around the axial direction of the telescopic section 112.

[0037] Specifically, the second toothed ring 160 is used to disengage from the first toothed ring 150 along with the rotating seat 170 when the second roller brush mechanism 130 is subjected to external force, so that the first toothed ring 150 and the second toothed ring 160 are temporarily separated, thereby preventing the impact force on the second roller brush mechanism 130 from being transmitted to the drive mechanism 140 and causing damage to the drive mechanism 140. In this way, the safety cleaning device 100 can achieve emergency release when the second roller brush mechanism 130 is involved in a collision, so as to prevent damage to the drive mechanism 140, improve safety, and extend the service life of the drive mechanism 140.

[0038] Furthermore, during the use of the safety cleaning device 100, firstly, the telescopic arm 110 drives the second roller brush mechanism 130 away from the first roller brush mechanism 120, so that a preset space is formed between the first roller brush mechanism 120 and the second roller brush mechanism 130; then, the drive mechanism 140 drives the second roller brush mechanism 130 to rotate 90 degrees, so as to expose the preset space; then, the movement of the vehicle body makes the guardrail located within the preset space; then, the drive mechanism 140 drives the second roller brush mechanism 130 to rotate 90 degrees, so that the guardrail is located between the first roller brush mechanism 120 and the second roller brush mechanism 130; then, the telescopic arm 110 drives the second roller brush mechanism 130 closer to the first roller brush mechanism 120, so that both the first roller brush mechanism 120 and the second roller brush mechanism 130 are in contact with the guardrail; finally, the first roller brush mechanism 120 and the second roller brush mechanism 130 are activated to clean the guardrail.

[0039] Preferably, the safety cleaning device 100 further includes an elastic element 180. The elastic element 180 is connected to the rotating seat 170 and is used to apply elastic force to the rotating seat 170 so that the rotating seat 170 drives the second toothed ring 160 to reset and return to the engagement state with the first toothed ring 150. During this process, the rotating seat 170 also drives the second roller brush mechanism 130 to reset, so as to ensure the cleaning effect of the second roller brush mechanism 130.

[0040] Furthermore, a baffle 113 is provided at the end of the telescopic section 112 away from the fixed section 111. An elastic element 180 is sleeved on the telescopic section 112, always in a compressed state. One end of the elastic element 180 abuts against the baffle 113, and the other end abuts against the rotating seat 170, applying a spring force to the rotating seat 170. This causes the rotating seat 170 to tend to move closer to the fixed section 111, thereby causing the second toothed ring 160 to tend to move closer to the first toothed ring 150, facilitating the reset function of the second toothed ring 160. Thus, when the second brush mechanism 130 is impacted, the second toothed ring 160 firstly disengages from the first toothed ring 150 along with the rotating seat 170. Subsequently, the second toothed ring 160 resets under the action of the elastic element 180 and engages with the first toothed ring 150. These two actions are completed rapidly within a short time, achieving the tooth-skipping function, effectively protecting the drive mechanism 140 and preventing damage, ensuring safety and reliability.

[0041] The drive mechanism 140 includes a fixed base 141, a drive member 142, and a transmission assembly 143. The fixed base 141 is connected to the telescopic section 112, which can drive the fixed base 141 away from or towards the fixed section 111. Specifically, the drive member 142 is mounted on the fixed base 141 and is connected to the first toothed ring 150 through the transmission assembly 143. The drive member 142 can drive the first toothed ring 150 to rotate through the transmission assembly 143, thereby driving the rotating seat 170 and the second roller brush mechanism 130 to rotate through the cooperation of the first toothed ring 150 and the second toothed ring 160.

[0042] In this embodiment, the transmission assembly 143 includes a gear 1431 and a rack 1432. The gear 1431 is rotatably sleeved on the telescopic section 112, and the gear 1431 can rotate relative to the telescopic section 112. The telescopic section 112 can limit the movement of the gear 1431. The driving member 142 is connected to the rack 1432, and the rack 1432 meshes with the gear 1431. The gear 1431 is connected to the first toothed ring 150. The driving member 142 can drive the rack 1432 to move along its length direction, thereby driving the gear 1431 to rotate relative to the telescopic section 112, and further driving the first toothed ring 150 to rotate relative to the telescopic section 112.

[0043] Furthermore, a bearing 114 is fitted over the telescopic section 112. The gear 1431 and the first toothed ring 150 are arranged side by side along the axial direction of the telescopic section 112 and are both fitted over the bearing 114. Both the gear 1431 and the first toothed ring 150 can rotate relative to the telescopic section 112 through the bearing 114. Specifically, the gear 1431 and the first toothed ring 150 are connected to the bearing 114 through a key 115. The gear 1431 can rotate under the drive of the rack 1432, thereby driving the bearing 114 to rotate through the key 115. The bearing 114, in turn, drives the first toothed ring 150 to rotate through the key 115. That is, the gear 1431, the first toothed ring 150, and the bearing 114 rotate synchronously under the action of the key 115, which is stable and reliable.

[0044] In this embodiment, the driving component 142 is a hydraulic cylinder. The free end of the piston rod 1421 in the driving component 142 is provided with an external thread 1422, and the rack 1432 has a threaded hole 1433. The external thread 1422 and the threaded hole 1433 cooperate to improve the stability of the connection between the piston rod 1421 and the rack 1432, and to facilitate installation and maintenance. However, it is not limited to this. In other embodiments, the driving component 142 can be a pneumatic cylinder or an electric cylinder, and the type of the driving component 142 is not specifically limited.

[0045] Preferably, the fixed base 141 is provided with a guide groove 1411, the extension direction of the guide groove 1411 is perpendicular to the axial direction of the telescopic section 112, the rack 1432 is slidably disposed in the guide groove 1411, the rack 1432 can slide along the extension direction of the guide groove 1411, and the guide groove 1411 can limit the rack 1432 to improve the stability of the rack 1432 during the sliding process.

[0046] It should be noted that the first toothed ring 150 includes multiple first teeth 151, which are connected end-to-end and form a ring; the second toothed ring 160 includes multiple second teeth 161, which are connected end-to-end and form a ring. Specifically, the first teeth 151 mesh with the second teeth 161 along the axial direction of the telescopic section 112. The drive mechanism 140 can drive the first toothed ring 150 to rotate around the axial direction of the telescopic section 112, so as to drive the second toothed ring 160 to rotate through the meshing of the first teeth 151 and the second teeth 161. When the second roller brush mechanism 130 is subjected to external force, the second toothed ring 160 disengages from the first toothed ring 150 along with the rotating seat 170, so that the first teeth 151 and the second teeth 161 are separated (disengaged).

[0047] The second roller brush mechanism 130 includes a connecting frame 131, a drive unit 132, and a roller brush 133. The connecting frame 131 is connected to a rotating seat 170, which can fix the connecting frame 131. The roller brush 133 is rotatably mounted on the connecting frame 131. The drive unit 132 is connected to the roller brush 133 in a transmission manner. The drive unit 132 can drive the roller brush 133 to rotate relative to the connecting frame 131 to clean the railing, thereby realizing the railing cleaning function.

[0048] In this embodiment, the specific structure of the first roller brush mechanism 120 is the same as that of the second roller brush mechanism 130, and will not be described again here.

[0049] The safety cleaning device 100 provided in this embodiment of the utility model includes a telescopic arm 110 comprising a fixed section 111 and a telescopic section 112 that can extend or retract relative to the fixed section 111. A first roller brush mechanism 120 is installed on the fixed section 111, and a drive mechanism 140 is installed on the telescopic section 112 and connected to a first toothed ring 150. The first toothed ring 150 and a second toothed ring 160 cooperate and are both rotatably sleeved outside the telescopic section 112. The second toothed ring 160 is connected to a rotating seat 170, and a second roller brush mechanism 130 is installed on the rotating seat 170. The rotating seat 170 is rotatably sleeved outside the telescopic section 112. The second toothed ring 160 is used to disengage from the first toothed ring 150 along with the rotating seat 170 when the second roller brush mechanism 130 is subjected to external force. Compared with the prior art, the safety cleaning device 100 provided by this utility model, due to the use of a first toothed ring 150 and a second toothed ring 160 that cooperate with each other, as well as a rotating seat 170 connected to the second toothed ring 160, can achieve emergency release in the event of a collision, thereby preventing damage to the drive mechanism 140, improving safety, and extending the service life of the drive mechanism 140. This results in the safety cleaning device 100 having good cleaning effect and being safe and reliable.

[0050] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
