Description

Technical Field

[0001] This invention relates to the field of bridge railing cleaning, and more specifically to a bridge railing maintenance and cleaning device for bridge construction. Background Technology

[0002] Bridge railings are an important component of bridges, serving not only for protection and decoration but also affecting wind resistance and structural stability. Therefore, the maintenance and cleaning of bridge railings are essential for ensuring the normal operation of bridges and extending their service life. In some road and bridge railings, the outer walls are inaccessible, making manual cleaning difficult; thus, cleaning equipment is needed to clean the railings.

[0003] In related technologies, for cleaning bridge railings, for example, the prior art patent with publication number CN111119101B provides a road bridge railing cleaning device. This device is equipped with a brushing unit, which includes a brushing assembly and a drive assembly for driving the brushing assembly to move up and down. The drive assembly includes a first motor, a lead screw, and a belt transmission mechanism. The brushing assembly includes a mounting plate, a third electric push rod, a scissor mechanism, a mounting rod, and semi-circular brush strips. The two semi-circular brush strips close together to surround the railing. The drive assembly drives the mounting plate to move up and down, and the mounting plate drives the semi-circular brush strips to move up and down, thereby brushing the railing.

[0004] The existing technical solution mentioned above uses two semi-circular brush strips to surround and clean the railing. However, this cleaning structure cannot change the shape of the brush strips and can only be used to clean railings of the same shape. That is, it cannot be used to clean railings of different shapes, such as curved railings or arc railings, and its applicability is poor.

[0005] Therefore, providing a bridge railing maintenance and cleaning device for bridge construction is a problem worthy of research. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the purpose of this invention is to quickly measure the dimensions of cylindrical parts, making the operation simpler and more convenient.

[0007] The objective of this invention is achieved as follows:

[0008] The present invention provides a bridge railing maintenance and cleaning device for bridge construction, including a traction device and a lifting frame slidably connected to the traction device. Two cleaning frames are connected to the lifting frame, the two cleaning frames are arranged facing each other, and the distance between the two cleaning frames is adjustable.

[0009] It also includes multiple guide wheels and multiple cleaning wheels. The guide wheels and the cleaning wheels are disposed on the opposing surfaces of the two cleaning frames by an adjustable spacing adjustment component.

[0010] It also includes a water supply pipe, the outlet of which is located on the cleaning rack and corresponds to the cleaning wheel.

[0011] To further explain, the traction device is connected to a horizontally arranged transverse guide rail and a longitudinal guide rail that slides with the transverse guide rail. The transverse guide rail is arranged perpendicular to the traveling direction of the traction device. A vertically extending hydraulic push rod A is provided on the longitudinal guide rail. The telescopic end of the hydraulic push rod A is connected to the lifting frame.

[0012] To further explain, a sliding connecting arm B is slidably connected to the lifting frame, and the bottom end of the sliding connecting arm B is connected to the cleaning frame located on the inner side; a sliding connecting arm A is connected to the lifting frame via a hydraulic push rod B, and the bottom end of the sliding connecting arm A is connected to the cleaning frame located on the outer side.

[0013] Further explanation is that the adjustment component includes a scissor-type telescopic frame, and an electric push rod B is connected between the scissor-type telescopic frame and the cleaning frame;

[0014] The scissor telescopic frame includes several sets of connecting rods A and connecting rods B that intersect with the connecting rods A. The middle parts of the connecting rods A and the connecting rods B are rotatably connected, and the movable ends of two adjacent sets of connecting rods A and connecting rods B are rotatably connected end to end.

[0015] Furthermore, the guide wheel and the cleaning wheel are located at the rotatable connection between the connecting rod A and the connecting rod B.

[0016] Further explanation: A connecting frame is slidably connected along the length of the cleaning rack. The connecting frame has a vertical groove structure on the side facing the adjustment component. A sliding pin is provided at the connection point of the ends of the connecting rod A and the connecting rod B. The sliding pin is slidably engaged with the groove structure. A sliding rod is fixedly provided at the movable end of the connecting frame. A wheel frame slides on the sliding rod. The movable end of the wheel frame is connected to the guide wheel. A thrust spring is provided on the sliding rod to push the wheel frame to slide, so that the guide wheel contacts the surface of the railing.

[0017] Further explanation is that the drive assembly includes a bearing plate, on which two parallel transmission shafts rotate, and a motor B for driving one of the transmission shafts to rotate is connected to the bearing plate, and the two transmission shafts are linked by a belt drive.

[0018] A connecting plate corresponding to the wheel frame is provided between the two drive shafts, and a cleaning wheel that rotates with the connecting plate slides on the drive shaft;

[0019] The drive shaft has a polygonal cross-section, and the cleaning wheel is clearance-fitted with the drive shaft.

[0020] The connecting plate does not contact the transmission shaft, and the connecting plate is fixedly connected to the wheel frame.

[0021] To further explain, each of the cleaning racks is slidably connected with a plurality of cleaning brushes, the cleaning brushes being spaced apart from the cleaning wheel, and the cleaning brushes being linked to the cleaning wheel;

[0022] The cleaning brush is equipped with a transmission assembly for driving all of the cleaning brushes to rotate.

[0023] To further explain, the transmission assembly includes a shaft bracket, which is slidably disposed with the cleaning frame. A drive shaft is rotatably mounted on the shaft bracket, and the working end of the drive shaft extends to the outside of the cleaning wheel and is connected to the cleaning brush.

[0024] The drive shaft is provided with a pulley B on its outer side, and all the connecting rods A and B are rotatably connected to a double pulley and a pulley A at the middle connection position;

[0025] The double pulleys and pulley A are connected to the same drive shaft. Pulley A and pulley B are driven by a drive belt. Two adjacent double pulleys are linked by two sets of drive belts.

[0026] It also includes motor A, whose output shaft is connected to any of the transmission shafts.

[0027] To further explain, the cleaning brush includes a brush head connected to the end of the drive shaft, a brush strip rotatably connected to the brush head via a support rod A, a slide bar corresponding to the support rod A sliding on the outer wall of the brush head, and a support rod B rotatably connected between the slide bar and the brush strip.

[0028] Further explanation: A horizontal electric push rod A is connected to the cleaning rack. The telescopic end of the electric push rod A is connected to a track. The track is provided with a groove extending along the length of the cleaning rack. A slider corresponding to a plurality of cleaning brushes is slidably connected in the groove. A sliding shaft that slidably engages with the drive shaft is connected to the slider. The movable end of the sliding shaft extends to the outer end of the brush head. All the sliders corresponding to the drive shaft are connected to the corresponding sliding shafts.

[0029] Positive and beneficial effects:

[0030] 1. By using the lifting frame to raise and lower, the guide wheels can move along the railing, thereby guiding the cleaning wheels and enabling the cleaning wheels to clean both straight and curved railing surfaces, making it suitable for a wide range of applications.

[0031] 2. By adjusting the distance between the guide wheel and the cleaning wheel using the adjustment component, the cleaning brush can be used to clean the railing surface with different spacing, resulting in a good cleaning effect;

[0032] 3. The transmission component drives all the cleaning brushes to rotate, so that the cleaning brushes clean the area between the two railings. The spacing of the cleaning brushes can be adjusted by the adjustment component, so that they can always be positioned between the two cleaning wheels to achieve a thorough cleaning of the railing.

[0033] 4. When the drive slider slides on the brush head, the support rod can pull the brush strip to move, and the distance between the brush strip and the brush head can be adjusted. That is, the cleaning brush can adjust the cleaning diameter. After adjusting the cleaning diameter of the brush strip according to the spacing of the railing, the cleaning brush is suitable for cleaning railings with different spacing.

[0034] 5. The guide wheel, cleaning wheel, and cleaning brush in the device can be synchronously adjusted according to the adjustment of the adjustment component, resulting in better linkage, simple and convenient operation, and good performance. Attached Figure Description

[0044] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0045] See Figures 1-8 As shown, the present invention provides a bridge railing maintenance and cleaning device for bridge construction, including a traction device 1. The traction device 1 is a vehicle structure, and a lifting frame 14 is slidably connected vertically inside the vehicle body of the traction device 1. Two cleaning frames 2 are connected to the lifting frame 14. See [reference needed]. Figure 1 , Figure 2 As shown, the cleaning frame 2 extends along the length of the vehicle body, that is, the extension direction of the cleaning frame 2 is in the same direction as the traction direction of the traction device 1. The two cleaning frames 2 are set facing each other, and the distance between the two cleaning frames 2 is adjustable. When in use, the distance between the two cleaning frames 2 can be adjusted. When the cleaning frame 2 is adjusted to a larger distance, the railing can be placed between the two cleaning frames 2 by sliding the lifting frame 14 up and down.

[0046] See Figure 4 , Figure 5 As shown, it also includes multiple guide wheels 3 and multiple cleaning wheels 4. The guide wheels 3 and cleaning wheels 4 are set on the opposing surfaces of the two cleaning frames 2 through an adjustable spacing adjustment component 6. The guide wheels 3 and cleaning wheels 4 are rotatably connected to the adjustment component 6. As the lifting frame 14 rises and falls, the guide wheels 3 can rotate along the outer wall of the railing, thereby guiding the cleaning wheels 4. Thus, the cleaning wheels 4 can always be in the corresponding position with the railing during the movement.

[0047] There are multiple cleaning wheels 4, and the multiple cleaning wheels 4 are evenly distributed, that is, the interval between the multiple cleaning wheels 4 is consistent. The cleaning frame 2 is equipped with a drive component for rotating all the cleaning wheels 4. The drive component can drive all the cleaning wheels 4 to rotate. During the rotation of the cleaning wheels 4, the surface of the railing can be cleaned. The cleaning wheels 4 on the two cleaning frames 2 can be used to achieve synchronous cleaning of both sides of the railing.

[0048] It also includes a water supply pipe 8, the outlet of which is located on the cleaning frame 2 and corresponds to the cleaning wheel 4. The inlet of the water supply pipe 8 is connected to the water supply equipment, which includes a water pipe, a water tank, a water pump, valves and other structures. The water supply equipment can be installed on the traction equipment 1, using the water supply pipe 8 to transport water, and cooperating with the outlet on the water supply pipe 8 to spray the railing.

[0049] When the railing needs to be cleaned, the lifting frame 14 is moved by the traction device 1, so that the cleaning frame 2 is positioned above the railing. The distance between the two cleaning frames 2 is widened, and the distance between the two adjacent guide wheels 3 is adjusted by the adjusting component 6, so that the guide wheels 3 correspond to the position of the railing. That is, the guide wheels 3 and cleaning wheels 4 are evenly arranged outside the adjusting component 6. The lifting frame 14 is adjusted downward, and the cleaning frames 2 are brought closer to each other until the guide wheels 3 are close to the outside of the railing. The cleaning wheels 4 on the two cleaning frames 2 form a surround around the railing. Water is supplied by the water supply pipe 8, and the water is sprayed onto the cleaning wheels 4 and the railing through the water outlet. As the lifting frame 14 moves downward, the cleaning wheels 4 clean the outside of the railing, so as to facilitate a thorough cleaning of the curved railing.

[0050] In the connection between the lifting frame 14 and the traction device 1, see Figure 3 , Figure 1 As shown, the traction device 1 is connected to a horizontally arranged transverse guide rail 11 and a longitudinal guide rail 12 that slides with the transverse guide rail 11. The transverse guide rail 11 is perpendicular to the direction of travel of the traction device 1. The longitudinal guide rail 12 can slide horizontally outside the transverse guide rail 11, thereby realizing the left and right adjustment of the longitudinal guide rail 12. The longitudinal guide rail 12 is provided with a vertically extending hydraulic push rod A13. The telescopic end of the hydraulic push rod A13 is connected to the lifting frame 14. After the hydraulic push rod A13 is extended or shortened, the lifting frame 14 can be pulled up and down by the hydraulic push rod A13, thereby realizing the height adjustment of the lifting frame 14 and the cleaning frame 2. By repeatedly raising and lowering the hydraulic push rod A13, the cleaning wheel 4 in the cleaning frame 2 can reciprocate to clean the guardrail. After cleaning, the hydraulic push rod A13 drives the lifting frame 14 to move, so that the lifting frame 14 is close to the longitudinal guide rail 12. The longitudinal guide rail 12 slides outside the transverse guide rail 11 through the telescopic device, thereby placing the cleaning frame 2 on the traction device 1, realizing the storage operation of the device.

[0051] Furthermore, the traction device 1 is provided with a receiving tray for storing the cleaning frame 2, which can fix and limit the cleaning frame 2 when the traction device 1 is started after storing the cleaning frame 2, so that the cleaning frame 2 is more fixed.

[0052] In a specific implementation, the transverse guide rail 11 is connected to the vehicle body through a right-angle bracket. When the device is stored after use, the cleaning rack 2 can enter the traction device 1 through the right-angle bracket.

[0053] See Figure 1 , Figure 3 As shown, when the lifting frame 14 is connected to the two cleaning frames 2, a sliding connecting arm B22 is slidably connected to the lifting frame 14, and the bottom end of the sliding connecting arm B22 is connected to the inner cleaning frame 2; a sliding connecting arm A21 is connected to the lifting frame 14 via a hydraulic push rod B23, and the bottom end of the sliding connecting arm A21 is connected to the outer cleaning frame 2. The inner and outer cleaning frames 2 are arranged facing each other. The hydraulic push rod B23 is located on the upper surface of the lifting frame 14. The cross-section of the sliding connecting arm A21 is right-angled. The horizontal end is connected to the telescopic end of the hydraulic push rod B23, and the vertical end of the sliding connecting arm A21 is connected to the cleaning frame 2. The sliding connecting arm B22 and the hydraulic push rod B23 are used to assist the inner cleaning frame 2 and the outer cleaning frame 2 in adjusting their positions, thereby realizing the adjustment of the distance between the two cleaning frames 2. That is, the opening and closing of the two cleaning frames 2 can be controlled. After the cleaning frame 2 approaches the railing, the sliding connecting arm B22 and the hydraulic push rod B23 are used to adjust the cleaning frame 2 to ensure that the cleaning operation is carried out smoothly.

[0054] The sliding connecting arm B22 can be a hydraulic telescopic structure, an electric telescopic structure, or a pneumatic telescopic structure.

[0055] When connecting the sliding connecting arm B22 to the cleaning rack 2 and the sliding connecting arm A21 to the cleaning rack 2, since the cleaning rack 2 is relatively long, a trapezoidal connecting structure can be connected to the top of the cleaning rack 2. That is, the bottom of the sliding connecting arm B22 is connected to the inner cleaning rack 2 through the trapezoidal connecting structure, and the bottom of the sliding connecting arm A21 is connected to the outer cleaning rack 2 through the trapezoidal connecting structure. Example 2

[0056] The feature that differs from Example 1 is: See Figure 5 , Figure 6 As shown, the adjustment component 6 includes a scissor telescopic frame. An electric push rod B61 is connected between the scissor telescopic frame and the cleaning frame 2. The electric push rod B61 is the power source of the scissor telescopic frame. After the electric push rod B61 extends or retracts, it can pull the scissor telescopic frame to extend or retract.

[0057] In the specific structure of the scissor-type telescopic frame, the scissor-type telescopic frame includes several sets of connecting rods A62 and connecting rods B63 that cross and correspond to the connecting rods A62. Each set contains one connecting rod A62 and one connecting rod B63. The middle of the connecting rods A62 and B63 is rotatably connected, and the movable ends of two adjacent sets of connecting rods A62 and B63 are rotatably connected end to end. When the electric push rod B61 is connected to the scissor-type telescopic frame, the fixed end of the electric push rod B61 is connected to the cleaning frame 2, and the telescopic end of the electric push rod B61 is connected to the middle rotating part of the connecting rods A62 and B63.

[0058] When the electric push rod B61 extends, the vertical rotation positions of the connecting rods A62 and B63 move closer to the middle rotation position of the connecting rods A62 and B63, and the overall length of the scissor telescopic frame becomes longer. When the electric push rod B61 shortens, the vertical rotation positions of the connecting rods A62 and B63 move further apart, and the overall length of the scissor telescopic frame becomes shorter.

[0059] Furthermore, the guide wheel 3 and the cleaning wheel 4 are located at the rotatable connection between the connecting rod A62 and the connecting rod B63;

[0060] When the guide wheel 3 is connected to the adjusting assembly 6, see Figure 6 As shown, multiple connecting frames 33 are slidably connected along the length of the cleaning frame 2. The cross-section of the connecting frame 33 is a "door" shaped structure. A vertical groove structure is provided on the vertical side wall of the connecting frame 33 facing the adjustment component 6. A sliding pin 64 is provided at the connection point of the ends of the connecting rod A62 and the connecting rod B63. The sliding pin 64 is a cylindrical structure and is evenly distributed along the length of the scissor-type telescopic frame of the adjustment component 6. The sliding pin 64 is slidably engaged with the groove structure. A sliding rod 32 is fixedly provided at the movable end of the connecting frame 33. A wheel frame 31 slides on the sliding rod 32. A guide wheel 3 is provided at the movable end of the wheel frame 31. A thrust spring 34 is provided on the sliding rod 32 to push the wheel frame 31 to slide, so that the guide wheel 3 contacts the surface of the railing. Utilizing the elasticity of the thrust spring 34, the wheel frame 31 can be pushed to slide outside the sliding rod 32. The wheel frame 31 pushes the guide wheel 3 to move towards the railing, so that the guide wheel 3 contacts the surface of the railing, thereby guiding the railing.

[0061] Among them, the slide bar 32 is a rod-shaped structure, and the movable end of the slide bar 32 is provided with a stop block to limit the wheel frame 31;

[0062] The slide bar 32 has a frame-shaped structure or a "U"-shaped structure, and the wheel frame 31 slides in contact with one of the side walls of the slide bar 32;

[0063] The wheel frame 31 has a right-angled, "U"-shaped or frame-shaped structure. The wheel frame 31 is slidably engaged with the slide bar 32, and the wheel frame 31 extends along the length of the slide bar 32.

[0064] In a preferred embodiment, the wheel frame 31 has a "U" shaped structure. The open end of the wheel frame 31 is rotatably connected to the guide wheel 3, and the sealed end of the wheel frame 31 is slidably engaged with the slide rod 32. The slide rod 32 has a rod-shaped structure, and the movable end of the slide rod 32 is provided with a stop block that limits the wheel frame 31. The stop block is in the shape of a broken line, with one end connected to the slide rod 32 and the other end connected to the wheel frame 31, thereby improving the fixing effect of the slide rod 32.

[0065] When connecting the connecting frame 33 and the cleaning frame 2, the cleaning frame 2 is provided with a slide rail extending along its length direction. The horizontal side wall of the connecting frame 33 is provided with a sliding sleeve that is fitted with the slide rail with a clearance. The sliding sleeve and the slide rail are used to guide the connecting frame 33, so that the connecting frame 33 can slide smoothly along the length direction of the cleaning frame 2. Preferably, the slide rail has a circular cross section and there are two of them.

[0066] During the installation of the cleaning wheel 4 and the adjusting assembly 6, see [reference needed]. Figure 5 As shown, the drive assembly includes two bearing plates 42, which are located close to both sides of the length of the cleaning rack 2. There are two parallel transmission shafts 43 that rotate between the two bearing plates 42. The transmission shafts 43 extend along the length of the cleaning rack 2. A motor B41 for driving one of the transmission shafts 43 to rotate is connected to the bearing plate 42. The two transmission shafts 43 are linked by a belt drive. When the motor B41 is working, the motor B41 can drive the transmission shaft 43 connected to it to rotate, and the synchronous rotation of the two transmission shafts 43 is achieved by the belt drive.

[0067] A connecting plate 44 corresponding to the wheel frame 31 is provided between the two drive shafts 43. A cleaning wheel 4 that rotates with the connecting plate 44 slides on the drive shaft 43. The cross section of the drive shaft 43 is polygonal. The cleaning wheel 4 and the drive shaft 43 are in clearance fit. When the drive shaft 43 rotates, the drive shaft 43 can drive the cleaning wheel 4 to rotate synchronously. The connecting plate 44 does not contact the drive shaft 43. The connecting plate 44 is fixedly connected to the wheel frame 31. When the wheel frame 31 is adjusted, the drive shaft 43 can be moved through the wheel frame 31.

[0068] Preferably, the cross-section of the drive shaft body 43 is a regular polygonal structure or a swivel shaft structure;

[0069] Furthermore, the bearing plates 42 are located on both sides of the length of the cleaning frame 2, and are both located on the outside of the cleaning frame 2. The drive shaft 43 passes through both sides of the length of the cleaning frame 2 and is connected to the bearing plates 42. The drive shaft 43 needs to move laterally. On both sides of the length of the cleaning frame 2, there are strip-shaped groove structures perpendicular to the drive shaft 43. This arrangement allows the motor B41 to be located on the outside of the cleaning frame 2, which is not only easy to maintain, but also provides a certain degree of waterproofing during operation. It also makes it easy to add a waterproof cover or other protective structure to the outside of the motor B41, which is beneficial to the use of the equipment and increases its service life. Example 3

[0070] The difference from Embodiment 2 is that: multiple cleaning brushes 5 are slidably connected to any cleaning rack 2, the cleaning brushes 5 correspond to the side wall of the railing, the cleaning brushes 5 and cleaning wheels 4 are spaced apart, and the cleaning brushes 5 and cleaning wheels 4 are linked, that is, the cleaning brushes 5 and cleaning wheels 4 are arranged in the form of "cleaning wheel 4-cleaning brush 5-cleaning wheel 4", see [reference]. Figure 6 As shown, the cleaning brush 5 is located between the two cleaning wheels 4. When the cleaning wheels 4 clean the front and back surfaces of the railing, the cleaning brush 5 can clean the facing surfaces between the two railings. The cleaning brush 5 can move with the movement of the cleaning wheels 4, so the cleaning brush 5 can accurately correspond to the position between the railings.

[0071] The cleaning brush 5 is equipped with a transmission component for driving all the cleaning brushes 5 to rotate. The transmission component drives all the cleaning brushes 5 to rotate, and the rotating cleaning brushes 5 can clean the opposing surfaces of the two railings, resulting in a good cleaning effect on the railings.

[0072] See Figure 7 , Figure 8 As shown, in the transmission assembly, the transmission assembly includes a shaft frame 52, which is slidably disposed with the cleaning frame 2. The shaft frame 52 has a gate-shaped structure, and its horizontal sidewall is slidably engaged with the cleaning frame 2. The vertical sidewall of the shaft frame 52 has a rotatable drive shaft 51 at its movable end. The working end of the drive shaft 51 extends to the outside of the cleaning wheel 4 and is connected to the cleaning brush 5.

[0073] In the connection between the shaft bracket 52 and the cleaning frame 2, the cleaning frame 2 is provided with a rod-shaped structure extending along its length direction, and the shaft bracket 52 is provided with a sliding ring. The sliding ring and the rod-shaped structure slide together, which can play a sliding guiding role for the shaft bracket 52.

[0074] A pulley B72 is provided on the outer side of the drive shaft 51. All connecting rods A62 and B63 are rotatably connected to double pulleys 65 and pulley A71 at the middle connection position. The double pulleys 65 and pulley A71 are connected to the same drive shaft. The pulley A71 and pulley B72 are driven by a drive belt. Two adjacent double pulleys 65 are linked by two sets of drive belts.

[0075] It also includes a motor A7, whose output shaft is connected to any transmission shaft. The motor A7 can drive the transmission shaft to work. When any transmission shaft rotates, the pulley A71 and the double pulley 65 on the rotating shaft rotate. Then, the pulley A71 can drive the corresponding pulley B72 to rotate. That is, the rotation of the cleaning brush 5 is realized through the drive shaft 51. After the double pulley 65 rotates, the rotation of the double pulley 65 is realized by two sets of belt drives. The double pulley 65 realizes the rotation of the pulley A71 located on the rotating shaft, and finally realizes the rotation of all the cleaning brushes 5. The cleaning brushes 5 realize the cleaning operation of the gap between two adjacent guardrails.

[0076] When installing motor A7, it can be slidably connected to the cleaning rack 2 to connect motor A7 to the sliding plate-shaped or strip-shaped structure. The plate-shaped or strip-shaped structure is connected to a matching guide strip, and one end of the guide strip is connected to the inner side of the cleaning rack 2 to realize the installation of motor A7.

[0077] In the preferred embodiment, motor A7 can be fixed by connecting it to connecting rod A62 or connecting rod B63. This makes it easier to fix motor A7, and when adjusting component 6 extends or retracts, motor A7 will rotate slightly, which will also cause cleaning brush 5 to deflect at an angle without affecting the working state of cleaning brush 5.

[0078] In a preferred embodiment, the double pulleys 65 and pulley A71 are located on the left and right sides of the adjusting assembly 6, respectively.

[0079] In the belt drive linkage structure between the double pulleys 65, a sliding pin 64 is connected at the connection position of the upper movable end of the connecting rod A62 and the connecting rod B63, and a pulley is rotatably connected at the connection position of the bottom movable end of the connecting rod A62 and the connecting rod B63. As the scissor telescopic frame extends and shortens, the distance between two adjacent double pulleys 65 will change, but the distance between the pulley and the double pulleys 65 will not change. A drive belt is connected between the pulley and the double pulleys 65. By using the cooperation of two sets of belt drives, the synchronous rotation of two adjacent double pulleys 65 can be achieved, the transmission is more stable, and all cleaning brushes 5 can rotate synchronously, ensuring the cleaning operation between the two railings.

[0080] The cleaning brush 5 includes a brush head 53 connected to the end of the drive shaft 51. The brush head 53 is rotatably connected to a brush strip 54 via a support rod A55. A slide bar 56 corresponding to the support rod A55 slides on the outer circumferential surface of the brush head 53. A support rod B57 is rotatably connected between the slide bar 56 and the brush strip 54. In the device of the cleaning brush 5, the support rod B57 and the support rod A55 can form a stable support for the brush strip 54. There is a rotatable connection point between the brush strip 54 and the support rod B57, and there is also a rotatable connection point between the brush strip 54 and the support rod A55. The line connecting the two rotatable connection points, the support rod B57, the brush head 53, and the support rod A55 form a trapezoidal structure.

[0081] When the slider 56 slides away from the support rod A55, the distance between the support rod A55 and the support rod B57 increases, pulling the brush strip 54 toward the brush head 53. That is, the distance between the brush strip 54 and the brush head 53 decreases. When the cleaning brush 5 rotates, the outer brush strip 54 has a smaller cleaning diameter when it rotates.

[0082] When the slider 56 slides away from the support rod A55, the distance between the support rod A55 and the support rod B57 increases, pulling the brush strip 54 toward the brush head 53. That is, the distance between the brush strip 54 and the brush head 53 decreases. When the cleaning brush 5 rotates, the outer brush strip 54 has a smaller cleaning diameter when it rotates.

[0083] In summary, by using the sliding of the slider 56, the cleaning diameter of the brush 54 can be adjusted, making the cleaning brush 5 suitable for cleaning railings at different intervals.

[0084] Specifically, the brush head 53 can be a polygonal prism or a cylindrical structure. When the brush head 53 is a cylindrical structure, the outer circular surface of the brush head 53 is rotatably connected to the brush strip 54 through the support rod A55. The brush strip 54 is evenly distributed on the outer wall of the brush head 53. The outer circumferential surface of the brush head 53 is slidably connected to the slide bar 56 corresponding to the support rod A55. The support rod B57 is rotatably connected between the slide bar 56 and the brush strip 54. When the cleaning brush 5 is inserted between two railings, the sliding of the slide bar 56 can push and pull the support rod B57, thus changing the tilt angle of the support rod B57. The cleaning diameter of the brush strip 54 can be adjusted according to the actual distance between the railings, so that the cleaning brush 5 can be used for cleaning railings with different intervals.

[0085] The brush bar 54 can be curved, arc-shaped, or straight.

[0086] A horizontal electric push rod A511 is connected to the cleaning rack 2. The electric push rod A511 extends along the width direction of the cleaning rack 2. The telescopic end of the electric push rod A511 is connected to a track 510. The extension and retraction of the electric push rod A511 can push and pull the track 510 to move it. The track 510 is provided with a sliding groove extending along the length direction of the cleaning rack 2. The sliding groove is slidably connected to a slider 59 corresponding to a plurality of cleaning brushes 5. The slider 59 is connected to... A sliding shaft 58 is connected to the drive shaft 51, and the movable end of the sliding shaft 58 extends to the outer end of the brush head 53. All the sliding strips 56 corresponding to the drive shaft 51 are connected to the sliding shaft 58 on the drive shaft 51. When the track bar 510 moves, the slider 59 and the sliding shaft 58 move accordingly. As the sliding shaft 58 extends and retracts, it can pull the sliding strips 56 to move. The sliding strips 56 can slide on the outside of the brush head 53 to adjust the cleaning diameter of the brush bar 54. The operation is simple and the effect is good.

[0087] Furthermore, both the drive shaft 51 and the brush head 53 are cylindrical structures, and the inner walls of the drive shaft 51 and the brush head 53 are clearance-fitted with the slide shaft 58. The slide shaft 58 is slidably installed on the inner side of the drive shaft 51. The telescopic end of the slide shaft 58 passes through the drive shaft 51 and the brush head 53 and is connected to a connecting piece. All the slide bars 56 corresponding to the drive shaft 51 are connected to the connecting piece.
