The top plate 5 is a component for supporting and moving, and the guide frame 80 is mounted on the end side of the top plate 50 and supported by the top plate 5. The internal motor 90 is symmetrically arranged at the two ends of the guide frame 80, the roller 91 is installed at the lower part of the internal motor 90, and the cleaning brush is installed on the roller 91. The support base 10 is mounted on a rotating device 11, and the rotating device 11 is arranged on a cleaning vehicle, and the entire device is transported by the cleaning vehicle. The rotating device 11 includes a rotating motor 111, and the rotating motor 111 is connected to the support base 10 to control the entire device to turn the cleaning direction.

[0027] Figure 2It is a partial schematic diagram of the guardrail cleaning device provided by the embodiment of the present application. A driven frame 30 is also installed on the support base 10. The driven frame 30 and the active frame 20 are arranged side by side and in parallel. The bottom ends of the driven frame 30 and the active frame 20 are hinged to the support base 10, and the top ends are hinged to the top plate 50. A first oil cylinder 40 is also arranged on the support base 10 located on one side of the driven frame 30. The first oil cylinder 40 is hingedly installed on the support base 10, specifically located in the middle of the driven frame 20, and the piston rod of the oil cylinder is connected to the active frame 20. Because both ends of the main and driven frames are hinged, the active frame 20 can be swung as a whole under the push of the oil cylinder, and the driven frame 30 is further driven to move through the top plate 50, that is, the driven frame 30 and the active frame 20 move synchronously, and the top plate 50 always remains in the horizontal plane. When the piston rod pushes a long stroke, the height of the entire top plate 50 can be changed, that is, the cleaning height can be changed.

[0028] In order to further realize the horizontal movement of the cleaning brush, a second oil cylinder 70 can be horizontally installed on the top plate 50, the bottom of the second oil cylinder 70 is fixed on the top plate 50, and the piston rod is connected to the guide frame 80, so that the piston rod pushes the guide frame 80 to move horizontally. The guide frame 80 can be inserted into or installed in the mounting frame of the top plate 50 through a connecting rod to achieve sliding connection and support the guide frame 80.

[0029] The guide frame 80 is located on one side of the top plate 50, and at least one roller 91 is provided on the top plate 50 at one end thereof close to the guide frame 80 for downward rotation. In this embodiment, the roller 91 is connected to the inner motor 90 for transmission, and the inner motor 90 is fixedly mounted on the top plate 50, so that the inner motor 90 drives the roller 91 to rotate synchronously. There are two rollers 91, which are symmetrically arranged, so that the roller brush area is increased and the force on the top plate 50 is balanced.

[0030] The guide frame 80 is also fixedly mounted with a rotating shaft 100 on the side facing away from the top plate 50. The rotating shaft 100 and the second oil cylinder 70 are symmetrically distributed on both sides of the guide frame 80. A suspension bracket 110 is fixedly mounted on the rotating shaft 100; a third oil cylinder 120 is hinged at one end of the guide frame 80, and the piston rod of the third oil cylinder 120 is hinged to the suspension bracket 110. The function of the third oil cylinder 120 is to enable the suspension bracket 110 to rotate around the guide frame 80 with the rotating shaft 100 as the rotation center. At least one roller 91 is arranged on the suspension bracket 110 and driven by an external motor 130. In some embodiments, the external motor 130 is symmetrically distributed on the suspension bracket 110, and the roller 91 is installed at the lower part of the external motor 130, and the cleaning brush is installed on the roller 91. The inner motor 90 and the outer motor 130 form an inner and outer double-layer roller brush, which sandwiches the railing in the middle during cleaning, thereby improving the cleaning efficiency. Furthermore, a spray pipe 400 corresponding to the support roller 91 may be provided on the suspension bracket 110 and the top plate 50, and a plurality of spray heads facing the roller brush may be installed on the spray pipe 400 to spray water toward the cleaning brush.

[0031] Figure 3 It is a schematic diagram of a scene in which a guardrail cleaning device is applied to a cleaning vehicle. The supporting base 10 of the guardrail cleaning device 200 is arranged on a rotating device 11 on the cleaning vehicle. After the rotating device 11 is powered on, it drives the guardrail cleaning device 200 to rotate 180°. At the same time, by reversing the rotation direction of the inner and outer motor groups, the guardrail on the other side can be cleaned. The roller brush can be set to a more economical speed of 100-200r / min. Figure 4 It is a schematic diagram of the left-right reversing cleaning guardrail.

[0032] Figure 5 This is the installation diagram of the rotary device. Figure 6 1 is a cross-sectional schematic diagram of a rotary device, which includes a rotary motor 111, a connecting plate 112, a planar thrust bearing 113 and a chassis 114. The rotary motor 111 is connected to the chassis 114 by connecting bolts. The planar thrust bearing 113 is mounted on the output shaft 117 of the rotary motor 111. The support base 10 is pressed on the planar thrust bearing 113 and connected to the connecting plate 112 by connecting bolts. There are two planar thrust bearings 113, one for bearing the pressure of the support base 10 and upper parts, and the other for rotating the support base 10. The connecting plate 112 is connected to the support base 10 by connecting bolts. The rotary motor 111 is connected to the connecting plate 112 through a flat key 115, which is installed in the key slot of the rotary motor 111 and the key slot of the connecting plate 112, thereby connecting the rotary motor 111 and the connecting plate 112 together. The clamping nut 116 is used to connect the motor shaft 117 and the connecting plate 112 and prevent the flat key from coming out. The rotary motor 111 can use a stepper brake motor with a motor power of 3KW and a rotation angle of 180°. Figure 4 It should be noted that the rotary device can also be other structures, as long as the support base and the upper cleaning component can be reversed as a whole.

[0033] Workflow: The device is fixed on the rotating device 11 through the support base 10. After the cleaning vehicle arrives at the work site, the push rod of the third oil cylinder 120 is controlled to move, so that the suspension bracket 110 rotates 90 degrees counterclockwise relative to the guide frame 80, so that the outer and inner rollers 91 are 90 degrees apart. Then the push rod of the first oil cylinder 40 is controlled to move, so that the inner roller 91 is aligned with the outer side of the guardrail to be cleaned, and the outer roller 91 is located above the guardrail to be cleaned. The push rod of the second oil cylinder 70 is further controlled to move, so that the outer roller passes over the guardrail to be cleaned and moves to the upper side of the inner side of the guardrail to be cleaned. The push rod of the third oil cylinder 120 is reset to rotate the suspension bracket 110 90 degrees clockwise relative to the guide frame 80, and the push rod of the second oil cylinder 70 is controlled to move in the opposite direction to align the outer roller with the inner side of the guardrail to be cleaned. After completing the above steps, water is passed through the spray pipe, and the motor is turned on to drive each group of rollers to rotate, so that both sides of the guardrail are cleaned at the same time. After the cleaning operation is completed, the water supply to the spray pipe is cut off and the motor stops driving. Then, the push rod of the third oil cylinder 120 is controlled to rotate the suspension bracket 110 90 degrees counterclockwise relative to the guide frame 80, and then the push rods of the second oil cylinder 70, the first oil cylinder 40 and the third oil cylinder 120 are reset in sequence. The upper part of the rotating device 11 is connected to the support base 10. After the rotating device 11 is powered on, it drives the support base 10 to rotate 180°, and drives the above-mentioned cleaning device components to rotate 180° relative to the rotating device 11. At the same time, by reversing the rotation direction of the motor, the cleaning of the guardrail on the other side can be achieved.

[0034] In summary, the height and horizontal position of the top plate are controlled by the first oil cylinder; the horizontal position of the guide frame is controlled by the second oil cylinder; the rotation angle of the bracket relative to the guide frame is controlled by the third oil cylinder; and the rotating device is used to change the cleaning direction of the entire cleaning device. Through the mutual cooperation between the oil cylinders, the technical effect of aligning the inner and outer rollers on the guardrail cleaning device with the outer side of the guardrail to be cleaned, and aligning the outer rollers on it with the inner side of the guardrail to be cleaned is achieved; the motor drives the inner and outer rollers to rotate, and the spray pipe provides water at the same time, thereby achieving the technical effect of efficient automatic cleaning of the guardrail. Compared with related manual cleaning, it effectively ensures the safety of workers, reduces the labor intensity of workers, improves work efficiency, and reduces cleaning costs.
