Description

Technical Field

[0001] The invention relates to the technical field of coating devices, and in particular to a rolling coating device for bridge cables. Background Art

[0002] Bridge cables are the main load-bearing structures of suspension bridges, cable-stayed bridges and arch suspension bridges. They are in harsh working environments (moisture corrosion, wind erosion, stress corrosion, etc.) across rivers, lakes and seas. When an accident occurs, the bridge is prone to fire, causing deformation of the cables and even collapse of the bridge. Once damaged or ineffective, it will cause very serious safety accidents and economic losses. Therefore, in order to ensure the safety of the bridge structure, the cables must be protected.

[0023] Please refer to the attached Figure 1 To Attachment Figure 4 The present application provides a roller coating device for bridge cables, including a shell 100, and a roller coating assembly 200 and a moving assembly 300 connected to the shell 100, wherein the moving assembly 300 is used to control the movement of the roller coating device on the cable, and the roller coating assembly 200 is used to apply paint to the cable.

[0024] The roller coating assembly 200 includes four rollers 210 and at least one paint supply bottle 220. The four rollers 210 are respectively arranged on the inner walls of the four sides of the shell 100, so that they can surround the cable to be rolled and paint the outer surface of the cable.

[0025] The paint supply bottle 220 is disposed outside the housing 100. The paint supply bottle 220 is used to store paint and supply paint to the roller 210 through a hose 230, so that the roller 210 is always soaked in paint. When the paint in the paint supply bottle 220 is used up, the paint supply bottle 220 can be disassembled and refilled, which is very convenient. With the supply of the paint supply bottle 220, the roller coating device can complete the full surface of the cable once each round trip.

[0026] The moving assembly 300 includes a driving motor 310 and two running wheels 320 for holding the cable, the running wheels 320 and the roller 210 are respectively located at the two ends of the length direction of the housing 100, and the output shaft of the driving motor 310 is connected to one of the running wheels 320 to drive the running wheel 320 to rotate. Under the output of the driving motor 310, the roller coating device climbs along the cable through the running wheels 320 to complete the roller coating operation, thereby improving the operation efficiency.

[0027] In the above technical solution of the present application, the roller coating device includes a housing 100, and a roller coating assembly 200 and a moving assembly 300 connected to the housing 100. The roller coating assembly 200 includes four rollers 210 arranged on the inner walls of the four sides of the housing 100, and a paint supply bottle 220 for supplying paint to the rollers 210. The paint supply bottle 220 supplies paint to the rollers 210 through a hose 230. The moving assembly 300 includes a driving motor 310 and two running wheels 320 for holding the cable. Driven by the moving assembly 300, the roller coating device climbs along the cable, and the four rollers 210 automatically rotate to coat the cable. With the supply of the paint supply bottle 220, the roller coating device can complete the full surface coating of the cable once each time it goes back and forth, eliminating the need for manual climbing and greatly improving the work efficiency.

[0028] Preferably, the housing 100 includes a first housing 110, a second housing 120 and a bolt fastener 132, one end of the first housing 110 is connected to the second housing 120 through a hinge 131, the other end of the first housing 110 is provided with a first locking groove 111, and the other end of the second housing 120 is correspondingly provided with a second locking groove 121, and the bolt fastener 132 passes through the first locking groove 111 and the second locking groove 121 to connect the first housing 110 and the second housing 120. Since the relative position of the first locking groove 111 and the second locking groove 121 is adjustable, the first housing 110 and the second housing 120 can be closed or opened to a certain distance, and the final posture fixation is achieved by the bolt fastening. Through the opening and closing of the first housing 110 and the second housing 120, the two walking wheels 320 can be controlled to hold the cable with appropriate force to ensure the normal operation of the roller coating device. Preferably, the first housing 110 and the second housing 120 can both be U-shaped or arc-shaped, surrounding the peripheral side of the cable.

[0029] As an optional embodiment of the present invention, the roller coating device further includes a spring 410 and a swing arm 420. The walking wheel 320 and the roller 210 on the same side that are not connected to the driving motor 310 are connected to the housing 100 through the swing arm 420, and are hooked together through the spring 410. Under the pulling force of the spring 410, the walking wheel 320 and the roller 210 on the same side that are not connected to the driving motor 310 will move toward the cable, so that an elastic contact force is generated between the walking wheel 320 and the cable, and between the roller 210 and the cable. This elastic contact force can prevent the walking wheel 320, the roller 210 and the cable from being too close to each other on the one hand, and can effectively ensure the effective contact between the walking wheel 320, the roller 210 and the cable on the other hand. In the embodiment shown in the accompanying drawings, connecting rods 430 are provided at both ends of the spring 410, and bearings 431 are provided on the connecting rods 430. The bearings 431 cooperate with the rotating shaft 222 of the drum 210 / traveling wheel 320, so that the spring 410 can pull the drum 210 and the traveling wheel 320 through the connecting rods 430 without hindering the rotation of the drum 210 and the traveling wheel 320.

[0030] As a specific embodiment of the invention, the roller 210 includes a bracket 211 connected to the housing 100, a rotating shaft 222 rotatably disposed on the bracket 211, and a cloth layer 223 sleeved on the rotating shaft 222; the rotating shaft 222 is a hollow structure, and a plurality of through holes 224 are disposed on the surface, and the paint supply bottle 220 injects paint into the rotating shaft 222 through a hose 230. The paint injected into the rotating shaft 222 diffuses to the cloth layer 223 through the through holes 224, so that the roller 210 is always soaked in paint, and the cable can be continuously painted.

[0031] Preferably, the moving assembly 300 further comprises a motor mounting frame 330, a first bevel gear 340 and a second bevel gear 350, the driving motor 310 is mounted on the housing 100 via the motor mounting frame 330, the output shaft of the driving motor 310 is in transmission connection with the first bevel gear 340, one of the running wheels 320 is in transmission connection with the second bevel gear 350, and the first bevel gear 340 and the second bevel gear 350 are meshed. The output shaft of the driving motor 310 drives the running wheel 320 to rotate via the first bevel gear 340 and the second bevel gear 350, so as to control the movement of the roller 210 device on the cable. Preferably, the number of the paint supply bottles 220 is two, each of which is responsible for the paint supply of two adjacent rollers 210, and the two paint supply bottles 220 are respectively located on different sides of the housing.

[0032] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention shall be based on the protection scope of the claims.
