[0032] 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.

[0033] Please refer to the reference. Figures 1 to 5 This utility model embodiment provides a guardrail cleaning vehicle (not shown) for rapid cleaning of urban guardrails. It can buffer and dampen the roller brush assembly 150, preventing damage from external impacts during cleaning, with good buffering effect and strong safety.

[0034] It should be noted that the guardrail cleaning vehicle includes a vehicle body (not shown in the figure) and a crash-resistant cleaning mechanism 100. The crash-resistant cleaning mechanism 100 is installed on the vehicle body, and the vehicle body is used to drive the crash-resistant cleaning mechanism 100 to move along the extension direction of the guardrail. The crash-resistant cleaning mechanism 100 is used to perform roller brush cleaning on the guardrail during the movement.

[0035] The anti-collision cleaning mechanism 100 includes a fixed frame 110, a support arm 120, a mounting base 130, an elastic element 140, and a roller brush assembly 150. The support arm 120 is movably mounted on the fixed frame 110 and can move relative to the fixed frame 110. The fixed frame 110 can limit the movement of the support arm 120. The support arm 120 is cylindrical. The mounting base 130 is sleeved on the support arm 120 and rotatably engages with it. The roller brush assembly 150 is mounted on the mounting base 130 and can rotate with the mounting base 130 relative to the support arm 120. The support arm 120 can limit the movement of the mounting base 130. One end of the elastic element 140 is connected to the mounting base 130, and the other end is connected to the fixing frame 110. The elastic element 140 is used to buffer the mounting base 130 when the roller brush assembly 150 is subjected to external force and causes the mounting base 130 to rotate relative to the support arm 120, thereby reducing the amount of rotation of the mounting base 130 relative to the support arm 120 and gradually dissipating the impact force on the roller brush assembly 150 until the mounting base 130 returns to its original position. In this way, the roller brush assembly 150 can be buffered and shock-absorbing, avoiding damage to the anti-collision cleaning mechanism 100 due to external impacts during cleaning, with good buffering effect and strong safety.

[0036] The mounting base 130 includes a base body 131, a first connecting plate 132, and a second connecting plate 133. The base body 131 is connected to the first connecting plate 132, and the first connecting plate 132 and the second connecting plate 133 are detachably connected and together sleeved on the support arm 120. The first connecting plate 132 and the second connecting plate 133 can rotate simultaneously relative to the support arm 120. The base body 131 is connected to the roller brush assembly 150, and the roller brush assembly 150 can rotate relative to the support arm 120 along with the base body 131 and the first connecting plate 132 and the second connecting plate 133. Specifically, the detachable connection between the first connecting plate 132 and the second connecting plate 133 facilitates disassembly, maintenance, and component replacement.

[0037] Furthermore, the first connecting plate 132 includes a first straight section 1321, a first arc-shaped section 1322, and a second straight section 1323 connected in sequence; the second connecting plate 133 includes a third straight section 1331, a second arc-shaped section 1332, and a fourth straight section 1333 connected in sequence. The first straight section 1321 is bolted to the third straight section 1331, and the second straight section 1323 is bolted to the fourth straight section 1333, to facilitate installation and disassembly. The first arc-shaped section 1322 and the second arc-shaped section 1332 are together fitted onto the outside of the support arm 120, forming a circle whose dimensions match the dimensions of the support arm 120.

[0038] The support arm 120 includes a fixed base 126, an arm body 127, a fixing plate, and a curved plate 128. One end of the fixed base 126 is connected to the arm body 127 via the curved plate 128, and the other end is connected to the arm body 127 via the fixing plate (not shown) to fix the relative position of the fixed base 126 and the arm body 127. The fixed base 126 is rotatably connected to the fixing frame 110 via a pin 125, allowing the fixed base 126 to rotate relative to the fixing frame 110, which in turn guides and limits the movement of the fixed base 126. Specifically, there are two curved plates 128 spaced apart. The fixed base 126 is welded to the arm body 127 via the fixing plate and the two curved plates 128 to improve the connection strength between the fixed base 126 and the arm body 127.

[0039] Preferably, the support arm 120 further includes a crossbeam 129. The crossbeam 129 is connected to the fixed seat 126 and spaced apart from the fixed frame 110. An elastic element 140 is connected between the crossbeam 129 and the mounting base 130. The extension direction of the elastic element 140, the extension direction of the crossbeam 129, and the axial direction of the support arm 120 are perpendicular to each other. That is, the extension direction of the elastic element 140 and the extension direction of the crossbeam 129 are both tangential directions of the rotation of the mounting base 130 relative to the support arm 120, and the extension direction of the elastic element 140 is perpendicular to the extension direction of the crossbeam 129. Specifically, the crossbeam 129 is welded to the fixed seat 126 to improve the connection strength. When the roller brush assembly 150 is impacted by the outside and causes the mounting base 130 to rotate relative to the support arm 120, the elastic element 140 extends or shortens to apply elastic force to the mounting base 130, slowing down the rotation process of the mounting base 130 and reducing the amount of rotation of the mounting base 130, thereby achieving a buffering and shock absorption function.

[0040] Furthermore, the crossbeam 129 is provided with an adjusting bolt 1291, and the elastic element 140 is connected to the adjusting bolt 1291. The adjusting bolt 1291 is used to adjust the length of the elastic element 140, thereby adjusting the preload of the elastic element 140, and further adjusting the buffering force of the elastic element 140. Specifically, when the preload of the elastic element 140 is large, the buffering force of the elastic element 140 is large, and the elastic element 140 is not easily deformed, which allows the mounting base 130 to reset quickly; when the preload of the elastic element 140 is small, the buffering force of the elastic element 140 is small, and the elastic element 140 is easily deformed, which allows the mounting base 130 to reset slowly.

[0041] In this embodiment, there are two elastic elements 140, which are disposed opposite to each other on both sides of the support arm 120. The two elastic elements 140 work together to apply elastic force to the mounting base 130 simultaneously, thereby enhancing the buffering and shock absorption effect. Specifically, when the mounting base 130 rotates clockwise relative to the support arm 120, the first elastic element 140 shortens and the second elastic element 140 extends, and both elastic elements 140 can apply buffering elastic force to the mounting base 130; when the mounting base 130 rotates counterclockwise relative to the support arm 120, the first elastic element 140 extends and the second elastic element 140 shortens, and both elastic elements 140 can apply buffering elastic force to the mounting base 130.

[0042] In this embodiment, the fixing frame 110 includes two spaced-apart curved beams 111. A fixing seat 126 is disposed between the two curved beams 111. A pin 125 passes sequentially through one curved beam 111, the fixing seat 126, and the other curved beam 111, allowing the fixing seat 126 to rotate simultaneously relative to both curved beams 111, thereby achieving a rotatable connection between the fixing seat 126 and the fixing frame 110. Specifically, the pin 125 can be fixedly connected to the fixing seat 126 and rotatably engaged with the curved beam 111, or it can be rotatably engaged with the fixing seat 126 and fixedly connected to the curved beam 111. The connection method of the pin 125 is not specifically limited.

[0043] Preferably, a first limiting block 123 and a second limiting block 124 are provided on the outside of the support arm 120. The first limiting block 123 and the second limiting block 124 are spaced apart along the axial direction of the support arm 120. The mounting seat 130 is clamped between the first limiting block 123 and the second limiting block 124. The first limiting block 123 and the second limiting block 124 work together to stop and limit the mounting seat 130, preventing the mounting seat 130 from moving axially along the support shaft. In this embodiment, both the first limiting block 123 and the second limiting block 124 are welded to the outside of the support arm 120 to improve the connection strength.

[0044] Furthermore, there are multiple first limit blocks 123, which are spaced apart circumferentially along the support arm 120. There are also multiple second limit blocks 124, which are spaced apart circumferentially along the support arm 120. The multiple first limit blocks 123 and multiple second limit blocks 124 work together to improve the stopping and limiting effect on the mounting base 130, and further prevent the mounting base 130 from moving axially along the support shaft.

[0045] In this embodiment, the number of the first limiting block 123 and the second limiting block 124 is four, but it is not limited to this. In other embodiments, the number of the first limiting block 123 and the second limiting block 124 can be two or three. The number of the first limiting block 123 and the second limiting block 124 is not specifically limited.

[0046] In this embodiment, the bent plate 128 is welded to a portion of the first limiting block 123 (the two bent plates 128 are welded to the two first limiting blocks 123 in a one-to-one correspondence) to further improve the connection strength between the fixed seat 126 and the arm body 127.

[0047] The roller brush assembly 150 includes a connecting frame 151, a drive unit 152, and a roller brush 153. The connecting frame 151 is connected to a mounting base 130, which can fix the connecting frame 151. The roller brush 153 is rotatably mounted on the connecting frame 151. The drive unit 152 is connected to the roller brush 153 for transmission. The drive unit 152 can drive the roller brush 153 to rotate relative to the connecting frame 151 to clean the railing, thereby realizing the railing cleaning function.

[0048] Preferably, the support arm 120 is a telescopic arm. The arm body 127 of the support arm 120 includes a fixed section 121 and a telescopic section 122 that can extend or retract relative to the fixed section 121. The fixed section 121 is movably mounted on the fixed frame 110, and the mounting seat 130 is sleeved on the outside of the fixed section 121, that is, the roller brush assembly 150 is mounted on the fixed section 121. Further, the anti-collision cleaning mechanism 100 also includes an outer roller brush assembly 160, which is mounted on the telescopic section 122. The telescopic section 122 can move the outer roller brush assembly 160 away from or closer to the roller brush assembly 150, so that the roller brush assembly 150 and the outer roller brush assembly 160 are clamped on both sides of the guardrail. The roller brush assembly 150 and the outer roller brush assembly 160 work together to clean both sides of the guardrail simultaneously, improving cleaning efficiency and enhancing cleaning effect.

[0049] In this embodiment, the specific structure of the outer roller brush assembly 160 is the same as that of the roller brush assembly 150, and will not be described again here.

[0050] The anti-collision cleaning mechanism 100 provided in this embodiment of the utility model has a support arm 120 movably mounted on a fixed frame 110. A mounting base 130 is sleeved on the support arm 120 and rotatably engages with it. A roller brush assembly 150 is mounted on the mounting base 130. One end of an elastic element 140 is connected to the mounting base 130, and the other end is connected to the fixed frame 110. The elastic element 140 is used to buffer the mounting base 130 when the roller brush assembly 150 is subjected to external force and causes the mounting base 130 to rotate relative to the support arm 120. Compared with the prior art, the anti-collision cleaning mechanism 100 provided by this utility model, due to the use of a mounting base 130 rotatably engaging with the support arm 120 and an elastic element 140 connecting the mounting base 130 and the fixed frame 110, can buffer and dampen the roller brush assembly 150, avoiding damage to it due to external impacts during cleaning. It has a good buffering effect and strong safety, resulting in a good anti-collision effect and reliable safety for the guardrail cleaning vehicle.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model.
