Description

[0001] The invention relates to the technical field of spraying devices, and in particular to a 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.

[0003] In the prior art, in order to improve the heat resistance and flame retardancy of bridge cables, workers will apply putty materials on the surface of the cables.

[0025] Please refer to the attached Figure 1 To Attachment Figure 4 The present application provides a coating device for a bridge cable 300, including a traction mechanism 100 and a coater 200 connected to the traction mechanism 100, the coater 200 is used to apply coating to the bridge cable 300, and the traction mechanism 100 is used to drive the coater 200 to move on the bridge cable 300.

[0026] The traction mechanism 100 includes a mounting seat 110, a threaded rod 120, a stopper 130, a driving motor 140, and a pair of swing arms 150 at an angle. The threaded rod 120 is screwed with the mounting seat 110, and one end of the threaded rod 120 is connected to the stopper 130. The position of the stopper 130 can be adjusted by rotating the threaded rod 120. One end of the swing arm 150 is hinged to the mounting seat 110, and the other end of the swing arm 150 is provided with a first running wheel 160. The stopper 130 is sleeved on the outer side of the pair of swing arms 150 so that the swing arms 150 can be retracted under the drive of the threaded rod 120. Specifically, when the threaded rod 120 drives the stopper 130 to move away from the mounting seat 110, the stopper 130 retracts the pair of swing arms 150. A second running wheel 170 is provided on the side of the stopper 130 away from the mounting seat 110. The first running wheel 160 and the second running wheel 170 are both used to contact the cable 300. The drive motor 140 cooperates with the first running wheel 160 and / or the second running wheel 170 in transmission. After the stopper 130 retracts a pair of swing arms 150 under the drive of the threaded rod 120, the first running wheel 160 and the second running wheel 170 are attached to and clamp the bridge cable 300 together. The drive motor 140 drives the first running wheel 160 and / or the second running wheel 170 to rotate, so that the traction mechanism 100 can make a linear motion along the bridge cable 300, driving the applicator 200 to climb obliquely upward.

[0027] The coating device 200 is provided with a clamping channel 210, a first injection channel 220 and a second injection channel 230. The clamping channel 210 is provided with a plurality of rollers 240 for cooperating with the cable 300. The coating device 200 is matched with the bridge cable 300 through the plurality of rollers 240. The coating device 200 is provided with a first interface 250 and a second interface 260 for connecting an external pipeline. The first interface 250 and the second interface 260 are both used to input coating.

The aerogel and the solvent form a protective structure on the bridge cable 300 to improve the heat resistance and flame retardancy of the bridge cable 300.

[0028] When coating the bridge cable 300, the operator first adjusts the threaded rod 120 of the traction mechanism 100 so that the limiter 130 and the swing arm 150 are retracted toward the cable 300 until the first running wheel 160 and the second running wheel 170 are attached to and clamp the bridge cable 300, and then installs the coater 200 on the cable 300, so that the first interface 250 and the second interface 260 of the coater 200 are connected to the coating supply system. Finally, the motor of the traction mechanism 100 is turned on to make the traction mechanism 100 climb straight along the bridge cable 300, and the automatic coating operation of the bridge cable 300 is completed, thereby improving the operation efficiency and saving manpower.

[0029] In the above technical solution of the present application, the coating device for the bridge cable 300 includes a traction mechanism 100 and a coating device 200 connected to the traction mechanism 100. The coating device 200 is used to apply coating to the bridge cable 300. The traction mechanism 100 is used to drive the coating device 200 to move on the bridge cable 300. The traction mechanism 100 includes a mounting seat 110, a threaded rod 120, a stopper 130, a driving motor 140 and a pair of swing arms 150 at an angle. By adjusting the threaded rod 120 of the traction mechanism 100, the stopper 130 and the swing arm 150 can be retracted toward the cable 300 together, and the first running wheel 160 and the second running wheel 170 can be attached to and clamp the bridge cable 300 together, so that the traction mechanism 100 can move linearly along the bridge cable 300. The coating device 200 cooperates with the bridge cable 300 through a plurality of rollers 240. The coating device 200 is provided with a first interface 250 and a second interface 260 for connecting an external pipeline, and the first interface 250 and the second interface 260 are both used to input coating. Driven by the traction mechanism 100, the coating device 200 climbs straightly along the bridge cable 300 to complete the automatic coating operation of the bridge cable 300, saving manpower and avoiding safety accidents in high-altitude operations.

[0030] Please refer to the attached Figure 3 Preferably, the first injection channel 220 includes a first straight channel 221 connected to the first interface 250, and a first annular channel 222 connected to the first straight channel 221, and the first annular channel 222 surrounds the clamping channel 210, so that the paint injected into the first injection channel 220 can be applied to the entire circle of the bridge cable 300. The second injection channel 230 includes a second straight channel 231 connected to the second interface 260, and a second annular channel 232 connected to the second straight channel 231, and the second annular channel 232 surrounds the clamping channel 210, so that the paint injected into the second injection channel 230 can be applied to the entire circle of the bridge cable 300.

Since the applicator 200 includes a detachable upper cavity 201 and a lower cavity 202, it is convenient to install on the bridge cable 300 and remove it. It can be understood that a part of the first annular channel 222 is located in the upper cavity 201, and the other part is located in the lower cavity 202, and a complete first injection channel 220 is formed when the upper cavity 201 and the lower cavity 202 are closed. Similarly, a part of the second annular channel 232 is located in the upper cavity 201, and the other part is located in the lower cavity 202, and a complete second injection channel 230 is formed when the upper cavity 201 and the lower cavity 202 are closed.

Since the distance between the pair of limiting columns 132 is constant, when the limiting member 130 moves away from the mounting seat 110, the limiting column 132 applies force to the pair of swing arms 150 to make them close together, so that the first running wheel 160 and the second running wheel 170 are attached together and clamp the bridge cable 300. Further, the limiting member 130 also includes a bottom plate 133, the two sides of the bottom plate 133 are connected to the pair of clamping plates 131, the bottom plate 133 is arranged perpendicular to the threaded rod 120, and the threaded rod 120 applies force to the bottom plate 133 to drive the limiting member 130 to move.

[0033] Furthermore, the traction mechanism 100 further includes a spring 122. A flange 121 is provided on the threaded rod 120. The spring 122 is sleeved on the threaded rod 120, and the opposite ends of the spring 122 are respectively against the flange 121 and the bottom plate 133. The arrangement of the spring 122 enables the first running wheel 160 and the second running wheel 170 to have a certain elasticity in the clamping force of the cable 300. When the spring 122 is in a compressed state, the traction mechanism 100 can firmly clamp the cable 300. Preferably, a threaded hole is provided in the middle position of the mounting seat 110, and the threaded rod 120 cooperates with the threaded hole; an avoidance hole is provided in the middle position of the bottom plate 133, and the threaded rod 120 passes through the avoidance hole, so that the threaded rod 120 is in flexible contact with the limiter 130 only through the spring 122.
