Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction, and more specifically to a cleaning device for road and bridge guardrails. Background Technology

[0002] With the rapid development of modern industry, protective gear cleaning has also been widely used in the field of road and bridge construction.

[0003] For example, CN222435157U, Double-sided Guardrail Cleaning Machine. This utility model discloses a double-sided guardrail cleaning machine, which includes a walking device, a cleaning device, a water supply device, and a control system. The walking device includes an electrical control box, a gasoline engine, and a hydraulic drive motor. The cleaning device includes a stainless steel water spray gun, a cleaning brush, and a high-pressure water pump. The water supply device includes a water tank, a low-pressure water pump, and water pipes. The control system includes an operation panel and a hydraulic power unit. The control system is connected to the walking device, the cleaning device, and the water supply device. Through this structure, the cleaning device can swing horizontally, and the lifting cylinder can be controlled to adjust vertically, greatly improving cleaning efficiency. Furthermore, the control system can adjust the cleaning brush by controlling the adjusting cylinder, allowing the brush to clean both sides of the guardrail simultaneously, thus completing the guardrail cleaning task more efficiently. However, the guardrail cleaning structure described in this utility model is common in the market and cannot effectively clean the gaps between the guardrail uprights.

[0004] For example, CN222525265U describes a municipal cleaning device for guardrails. This utility model provides a municipal cleaning device for guardrails, relating to the field of guardrail cleaning devices. It includes a support assembly comprising a vertical plate, a first horizontal plate, and a second horizontal plate. The first and second horizontal plates are located on one side of the vertical plate and are movably connected to it. A flipping mechanism is provided between the first and second horizontal plates to flip the second horizontal plate. A cleaning mechanism is located below both the first and second horizontal plates for cleaning the guardrail. This utility model achieves the effect of cleaning the guardrail by setting up cleaning mechanisms, adjusting the height of the cleaning mechanism by setting up lifting mechanisms, and flipping the second horizontal plate by setting up flipping mechanisms to adjust it to the other side of the guardrail, reducing the possibility of collision between the cleaning mechanism and the guardrail. However, this guardrail cleaning structure is common in the market and cannot effectively clean the gaps between the guardrail vertical pipes. Summary of the Invention

[0032] This utility model discloses a cleaning device for road and bridge guardrails. Its advantages are as follows: Due to the structural characteristics of traditional guardrails, this device encloses the entire guardrail within the frame assembly 1 through gaps in the frame assembly 1. The device is driven by power mechanisms 2. Four sets of power mechanisms 2 are arrayed at the bottom of the frame 101 in the frame assembly 1. When the four sets of power mechanisms 2 are started simultaneously, the motor C201 is activated. When its output shaft rotates, it drives the wheel set 203 to rotate along the axle seats A204 and B205 via coupling 202. The rotation of the wheel set 203 then drives the entire device forward along the guardrail. The cleaning mechanisms 3 are installed in a layout of two sets on each side, totaling four sets, within the frame 101 of the frame assembly 1. The gaps between the two sets of cleaning mechanisms 3... The gaps in panels A102 and B126 of the frame assembly 1 are used to simultaneously activate four cleaning mechanisms 3. Motor D311 in cleaning mechanism 3 is activated, and its output shaft drives pulley E312 to rotate. Pulley E312 drives pulley F314 to rotate via belt C313. Pulley F314 drives cleaning roller 315 to rotate. Cleaning roller 315 has a metal shaft covered with a cloth cleaning sleeve. This ensures stable rotation of the cleaning roller 315's axis while the external cleaning cloth can rotate quickly, patting and scraping the outer surface of the guardrail. If the guardrail angle changes, the power mechanism 2 will cause the device to tilt. At this time, one side of the cleaning mechanism 3 will press against the guardrail. When the cleaning roller 315 is pressed, it will be connected to bracket 302. The pressure bearings C303 and E306 are squeezed. Bearing C303 squeezes bearing D305 through spring damper A304, and bearing E306 squeezes bearing F308 through spring damper B307. Bearings D305 and F308 apply force to the side of frame 101 in frame assembly 1, correcting the frame assembly 1 to the side of its tilt. While cleaning mechanism 3 is cleaning, water pumps A105 and B108 are started simultaneously. Water pump A105 draws water from water tank A104 and delivers it to water spray pipe A106, where it is then diffused and sprayed out by the diffuser nozzles. This reduces dust and wets cleaning roller 315 and annular cleaning cloth B125. When water pump B108 starts, it draws water from water tank B107. The water is delivered to the water spray pipe B109 and then sprayed out by the diffuser nozzles in the pipe, which not only reduces dust but also wets the cleaning roller 315 and the annular cleaning cloth A124. However, considering that the rotation angle of the cleaning roller 315 cannot effectively clean the gaps between the riser and the riser support in the guardrail (a common drawback in the market), motors A112 and B119 are started simultaneously. When motor A112 starts, its output shaft drives pulley A113 to engage the guardrail. Pulley A113 drives pulley B115 to rotate via belt A114. Belt A114 rotates, driving the annular cleaning cloth B125 to rotate. When motor B119 starts, its output shaft drives pulley C120 to rotate. Pulley C120 drives pulley D122 to rotate via belt B121.When belt B121 rotates, it drives the annular cleaning cloth A124 to rotate. As annular cleaning cloths A124 and B125 rotate synchronously, they clean the gaps in the guardrail.

[0033] Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples mentioned above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this utility model are also within the protection scope of this utility model.
