[0032] Embodiment 1

[0033] Referring to Figure 1 , this is the first embodiment of the present utility model. This embodiment provides a cleaning rack mechanism, which includes a cleaning rack unit 100.

[0034] The cleaning rack unit 100 includes a telescopic assembly 101, a cleaning assembly 102 slidably disposed on the telescopic assembly 101, a water absorption assembly 103 slidably disposed on the telescopic assembly 101, and a fixing assembly 104 slidably disposed on the telescopic assembly 101.

[0036] Embodiment 2

[0037] Refer to Figures 1 to 3 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the telescopic rod 101a pushes the connecting rod 101b to drive the two sliding sleeves 101c and the two mounting plates 101d to move, which can synchronously control the cleaning component 102 and the water absorption component 103, facilitating the water absorption component 103 to recycle the water sprayed by the cleaning component 102 and absorb and process the loose stone chips in the gaps of the asphalt pavement after high-pressure cleaning by the cleaning component 102; the guide plate 102a-5 has a sliding friction with the fixing component 104, causing the moving frame 102a-1 to drive the limit sliding plate 102a-3 to move, realizing the expansion of the horizontal working range of the moving frame 102a-1.

[0038] Preferably, the telescopic component 101 includes a telescopic rod 101a, a connecting rod 101b provided at the telescopic end of the telescopic rod 101a, sliding sleeves 101c provided at both ends of the connecting rod 101b, and mounting plates 101d provided at the bottom surfaces of the sliding sleeves 101c. There are two mounting plates 101d, and the two mounting plates 101d are respectively connected to the bottom surfaces of the two sliding sleeves 101c; the telescopic rod 101a pushes the connecting rod 101b to drive the two sliding sleeves 101c and the two mounting plates 101d to move, which can synchronously control the cleaning component 102 and the water absorption component 103, facilitating the water absorption component 103 to recycle the water sprayed by the cleaning component 102.

[0039] Furthermore, two through grooves 101d-2 are symmetrically provided on the bottom surface of the mounting plate 101d, an opening groove 101d-3 is provided on the bottom surface of the mounting plate 101d, and a communication groove 101d-4 communicating with the opening groove 101d-3 is provided on the upper end surface of the mounting plate 101d; a sliding groove 101d-1 is provided on the inner wall of the through groove 101d-2. Both the cleaning component 102 and the water absorption component 103 are slidably arranged in the through groove 101d-2, facilitating the fixing component 104 to push the cleaning component 102 and the water absorption component 103 to move.

[0040] Furthermore, the cleaning component 102 includes a first cleaning rack portion 102a slidably arranged on the mounting plate 101d and an ultrasonic nozzle 102b arranged on the bottom surface of the first cleaning rack portion 102a. The ultrasonic nozzles 102b are uniformly arranged on the bottom surface of the first cleaning rack portion 102a.

[0041] Among them, there are two first cleaning rack portions 102a arranged symmetrically along the central axis of the mounting plate 101d. The water absorption component 103 includes a second cleaning rack portion 103a slidably arranged on the mounting plate 101d and a suction nozzle 103b arranged on the bottom surface of the second cleaning rack portion 103a; the structures of the first cleaning rack portion 102a and the second cleaning rack portion 103a are exactly the same. The two first cleaning rack portions 102a move towards both sides, which can further expand the operation range.

[0042] Preferably, the first cleaning rack portion 102a includes a moving rack 102a-1 slidably arranged in the through groove 101d-2, a baffle 102a-2 arranged at one end of the moving rack 102a-1, a limiting sliding plate 102a-3 arranged on the moving rack 102a-1 and in sliding friction with the sliding groove 101d-1, a return spring 102a-4 arranged on the limiting sliding plate 102a-3 and connected to the inner wall of the sliding groove 101d-1, and a guiding plate 102a-5 arranged on the moving rack 102a-1 and cooperating with the fixing component 104. The guiding plate 102a-5 has sliding friction with the fixing component 104, so that the moving rack 102a-1 drives the limiting sliding plate 102a-3 to move, realizing the expansion of the horizontal operation range of the moving rack 102a-1.

[0043] Among them, a guiding inclined surface 102a-6 in sliding friction with the fixing component 104 is arranged on the bottom surface of the guiding plate 102a-5. When the first cleaning rack portion 102a moves downward, the guiding inclined surface 102a-6 contacts and presses the fixing component 104, causing the guiding inclined surface 102a-6 to slide.

[0044] Further, the fixing component 104 includes a fixing rod 104a that slides and rubs against the inner peripheral surface of the sliding sleeve 101c, and a fixing block 104b provided on the bottom surface of the fixing rod 104a. The telescopic component 101 slides along the fixing rod 104a, so that the guiding inclined surface 102a-6 moves to the lowest position and contacts the fixing block 104b. When the telescopic component 101 does not contact the fixing block 104b, the cleaning component 102 and the water absorption component 103 only displace in the vertical direction. When the telescopic component 101 contacts the fixing block 104b, the cleaning component 102 and the water absorption component 103 simultaneously displace in the vertical and horizontal directions, and the displacement amount in the vertical direction is affected by the height of the guiding plate 102a-5 and will not change much, enabling the cleaning component 102 and the water absorption component 103 to operate at an appropriate distance from the ground.

[0045] Furthermore, a fillet 104b-1 is provided on the upper end surface of the fixing block 104b. Through the sliding friction between the provided fillet 104b-1 and the guiding inclined surface 102a-6, the guiding plate 102a-5 is pushed to drive the moving frame 102a-1 to move, so that the cleaning frame part one 102a extends out, expanding the cleaning range; at the same time, when the moving frame 102a-1 moves, the reset spring 102a-4 is driven to be compressed, making the movement of the moving frame 102a-1 more stable. At the same time, when the telescopic rod 101a drives the mounting plate 101d to move in the reverse direction, the reset spring 102a-4 drives the moving frame 102a-1 to reset.

[0046] During use: The telescopic rod 101a pushes the connecting rod 101b to drive the two sliding sleeves 101c and the two mounting plates 101d to move, which can synchronously control the cleaning component 102 and the water absorption component 103, facilitating the recycling of the water sprayed by the cleaning component 102 by the water absorption component 103, and absorbing and treating the loose stone chips in the gaps of the asphalt pavement after high-pressure cleaning of the cleaning component 102; the guiding plate 102a-5 slides and rubs against the fixing component 104, so that the moving frame 102a-1 drives the limit sliding plate 102a-3 to move, realizing the expansion of the horizontal operation range of the moving frame 102a-1.
