Description

Technical Field

[0001] The present application relates to the field of bridge cable corrosion prevention, and in particular to a bridge cable corrosion prevention construction device and construction method. Background Art

[0002] For some bridges, most of the bridge cables are not protected. Since the bridge cables are used outdoors for a long time, they are easily affected by rain or the external environment, which causes the bridge cables to be easily corroded and cracked, affecting the safety of the bridge cables. Therefore, some bridge cable inspection robots have appeared. The inspection robots are equipped with high-definition cameras. The robots move along the direction of the cable trajectory and send the images of the bridge cables taken by the high-definition camera to the computer to facilitate the operator to inspect the safety of the cables.

[0003] Against the above background, in order to reduce the possibility of bridge cables being corroded, the inventors have developed a bridge cable anti-corrosion construction device and construction method based on the technology of bridge cable detection robots. Summary of the Invention

[0004] In order to reduce the possibility of bridge cables being corroded, the present application provides a bridge cable anti-corrosion construction device and construction method.

[0005] In the first aspect, the present application provides a bridge cable anti-corrosion construction device, which adopts the following technical solution:

[0006] A bridge cable anti-corrosion construction device includes an inspection robot, which is used to move along the length direction of the cable, and also includes a clamping mechanism, which is used to be installed on a mounting surface, and also includes a coating mechanism, which includes a mounting frame, a winding roller and a protective belt; the mounting frame is used to be installed on the inspection robot, the winding roller is rotatably connected to the mounting frame, one end of the protective belt is wrapped and fixedly connected to the winding roller, and the other end of the protective belt is used to be clamped by the clamping mechanism, the protective belt is provided with a plurality of notches at intervals on both sides along its own length direction, and the mounting frame is provided with a cutting mechanism for cutting the protective belt; it also includes a film locking mechanism, which includes a fixing frame, a pressing component arranged on the fixing frame and a hot-melt component arranged on the fixing frame, the fixing frame is used to be connected to the inspection robot to follow the inspection robot to move along the length direction of the cable, the pressing component is used to wrap the protective belt around the cable, and the hot-melt component is used to fuse both sides of the protective belt in the length direction.

[0007] By adopting the above technical solution, the protective belt can prevent rainwater from eroding the cable, and the inspection robot and the clamping mechanism are used to unwind the winding roller and pull the protective belt to the outside of the cable, and then the protective belt is wrapped around the outside of the cable through the clamping component, and then the two sides of the protective belt in the length direction are fused by the hot melt component to ensure that the protective belt will not detach from the cable. After the protective belt is fused, the protective belt is cut off by the cutting mechanism, and then the inspection robot can be removed from the cable. In addition, multiple notches are set at intervals on the protective belt, so that the protective belt can be constructed in sections, and it is also convenient for the clamping component to tighten the protective belt; through this construction device, the protective belt can be wrapped around the cable, reducing the possibility of corrosion of the bridge cable.

[0008] Optionally, the clamping component includes two mounting rods connected to a fixed frame for sliding along the thickness direction of the protective belt, the fixed frame is provided with a driving member for driving the mounting rods to slide, the shortest connecting line direction of the two mounting rods is used to be set along the width direction of the protective belt, the mounting rod is provided with a movable rod connected for sliding along the width direction of the protective belt, the ends of the two movable rods approaching each other are rotatably connected to a clamping roller, and the movable rod is provided with a spring for driving the clamping roller to slide away from the movable rod.

[0009] By adopting the above technical solution, when the protective belt is pulled onto the cable, the protective belt is in a flat state. At this time, the clamping roller is located on the side of the protective belt away from the cable. When the protective belt is wrapped around the cable, the driving member drives the mounting rod to slide along the thickness direction of the protective belt. Since the cross-section of the cable is circular, the clamping roller slides along the mounting rod, and the cable radius changes. The clamping roller compensates for the change in the cable radius under the action of the spring. In the process of moving the mounting rod, the clamping roller gradually wraps the protective belt around the outside of the cable. By using two mounting rods, the parts on both sides of the length direction of the protective belt can be wrapped around the outside of the cable at the same time. The clamping component has a simple structure and is easy to operate.

[0010] Optionally, the driving member includes a cylinder 1.

[0011] By adopting the above technical solution, when driving the mounting rod to slide, it is sufficient to open the cylinder 1; the driving component has a simple structure and is easy to operate.

[0012] Optionally, the hot melt component includes a hot melt plate, which is used to be installed on the fixing frame. When the protective belt covers the cable, the hot melt plate faces the intersection position of both sides of the protective belt in the length direction.

[0013] By adopting the above technical solution, when the clamping component covers the two sides of the protective belt in the length direction of the cable, the two sides of the protective belt in the length direction are close to each other. At this time, the hot melt plate is energized, and the hot melt plate generates heat to fuse the two sides of the protective belt in the length direction. The hot melt component has a simple structure and is easy to operate.

[0014] Optionally, the upper surface of the hot melt plate is in an inverted V shape.

[0015] By adopting the above technical solution, the hot melt plate can be easily inserted between the two pressing rollers to prevent bulges from occurring at the fusion position of the protective belt.

[0016] Optionally, the cutting mechanism includes a laser bar.

[0017] By adopting the above technical solution, when the protective strip needs to be cut, the laser bar can be turned on, and the cutting mechanism has a simple structure and is easy to operate.

[0018] Optionally, a roller is rotatably connected to the fixing frame, and the roller is used to abut against the outside of the protective belt and at a position tangent to the cable.

[0019] By adopting the above technical solution, it is convenient to fit the protective belt onto the cable.

[0020] In a second aspect, the present application provides a construction method for a bridge cable anti-corrosion construction device, which adopts the following technical solution:

[0021] A construction method for a bridge cable anti-corrosion construction device comprises the following steps: Step 1, installing a clamping mechanism on a mounting surface beside the cable to be constructed, then installing a detection robot on the cable, and installing a film locking mechanism on the detection robot; Step 2, installing a protective belt on the clamping mechanism; Step 3, moving the detection robot along the length direction of the cable; Step 4, wrapping the protective belt around the cable by a pressing component; Step 4, fusing both sides of the protective belt in the length direction by a hot-melt component.

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Reference Figure 1 The bridge cable anti-corrosion device used in this application is a protective belt 1, which is made of Teflon material. In the actual creation process, since the cable 2 is relatively long and the two ends of the cable 2 are fixed, the protective belt 1 is difficult to cover the cable 2. Based on this problem, this application has developed a bridge cable 2 anti-corrosion construction device.

[0034] The embodiment of the present application discloses a bridge cable anti-corrosion construction device. Figure 1 and Figure 2 The construction device includes a moving mechanism, a clamping mechanism, a coating mechanism and a locking mechanism. The moving mechanism is used to move along the length direction of the cable 2, the coating mechanism is used to provide the protective belt 1, the clamping mechanism is used to clamp one end of the protective belt 1, the moving mechanism drives the coating mechanism to move to attach the protective belt 1 to the outer wall of the cable 2, and the locking mechanism is used to wrap the protective belt 1 on the cable 2.

[0035] The moving mechanism includes a detection robot 3, which can be mounted on the cable 2 and move along the length direction of the cable 2 (this is prior art and will not be described in detail in this application).

[0037] Reference Figure 1 and Figure 3 The laminating mechanism includes a mounting frame 8, a winding roller 9 and a protective belt 1. The mounting frame 8 is used to be fixedly connected to the detection robot 3 by screws.

[0038] When in use, the clamping mechanism clamps the protective belt 1, and the motor 10 is turned on to unwind the winding roller 9. At the same time, the detection robot 3 moves along the length direction of the cable 2. During this process, it is only necessary to adjust the position of the mounting frame 8 so that the protective belt 1 can be attached to the cable 2 and tangent to the cable 2.

The plurality of rollers 12 are arranged at intervals along the length direction of the protective belt 1. The rotation axis of the roller 12 is arranged along the width direction of the protective belt 1 (the width direction, thickness direction and length direction of the protective belt 1 referred to in this application are all the states when the protective belt 1 and the cable 2 are tangent). The roller 12 abuts against the outside of the protective belt 1 and is tangent to the cable 2.

[0040] The clamping component includes two mounting rods 13 connected to the fixed frame 11 for sliding along the thickness direction of the protective belt 1. The fixed frame 11 is provided with a driving member for driving the mounting rod 13 to slide. The shortest connecting line direction of the two mounting rods 13 is used to be set along the width direction of the protective belt 1. The length direction of the mounting rod 13 is set along the thickness direction of the protective belt 1. A movable rod 14 is passed through the end of the mounting rod 13 away from the fixed frame 11. The cross-section of the movable rod 14 is rectangular. The length direction of the movable rod 14 is set along the width direction of the protective belt 1. The movable rod 14 is rotatably connected to the end of the cable 2.

When the spring 16 is not deformed, the clamping roller 15 is close to the tangent position of the protective belt 1 and the cable 2.

[0041] In this application, the driving member includes a cylinder 17, which is fixedly connected to the fixing frame 11, and the length direction of the cylinder 17 is arranged along the sliding direction of the mounting rod 13, and the telescopic end of the cylinder 17 is fixedly connected to the mounting rod 13.

[0042] The hot melt component includes a hot melt plate 18, and the length direction of the hot melt plate 18 is arranged along the length direction of the protective belt 1.

[0043] The hot melt plate 18 is located directly below the roller 12 , and the upper surface of the hot melt plate 18 is in an inverted V shape. After the pinch rollers 15 work to wrap the protective belt 1 around the cable 2 , the two pinch rollers 15 respectively abut against both sides of the upper end of the hot melt plate 18 .

[0044] The hot melt plate 18 adopts an electric heating method, and the heating part of the hot melt plate 18 is arranged at an inverted V-shaped structure.

[0045] In another embodiment, the hot melt component is heated by electric ignition, and the flame spraying portion is set at the inverted V-shaped structure.

[0046] In this embodiment, a plurality of notches 22 are provided on both sides of the protective belt 1 along its length direction to divide the protective belt 1 into multiple sections at equal intervals. The length of each section of the protective belt 1 is consistent with the length of the pressure roller 15. The setting of the notches 22 facilitates the protective belt 1 to be wrapped around the cable 2.
