Description

Technical Field

[0001] The invention relates to the field of cable detection, and in particular to a mobile detection platform for detecting ageing-resistant and flame-retardant cables. Background Art

[0002] Cable is a key component for power transmission and signal transmission, and is widely used in various industries, construction and communications. It consists of multiple conductors, insulation layers, sheaths and other additional materials. Since cables are laid outdoors, they are prone to aging and damage under the influence of the environment. The aging and damage of cables need to be discovered, repaired or replaced in time to avoid safety accidents and power transmission problems caused by cable damage. Cable laying mainly includes underground laying, underwater laying and high-altitude laying. When testing cables laid at high altitude, workers need to work at high altitude for a long time, which has a high risk of operation.

[0003] The prior art has the following deficiencies: In the prior art, there is a detection platform that can move along the outer wall of the cable. The detection platform is equipped with several cameras. The cameras collect video image information on the surface of the cable and transmit it to a receiving device. The receiving device receives the video image information collected by the camera and displays it, which is convenient for the staff to observe the surface state of the cable and find damaged cables in time; however, after the existing mobile detection platform detects damage on the surface of the cable, it is unable to mark the damaged position. Since the cables laid at high altitudes are far away and have a large span, even if the mobile detection platform can detect the damage of the cables laid at high altitudes, the workers cannot When the workers carry out subsequent high-altitude maintenance work, it is difficult to determine the specific location of the damaged cable, resulting in long high-altitude work time and high work risks. In addition, the existing mobile inspection platform can only clamp on one cable at a time for inspection, and there are usually multiple cables laid at high altitudes that are parallel to each other. This requires the traditional mobile inspection platform to move repeatedly on a similar path before it can inspect multiple parallel cables, resulting in low inspection efficiency. At the same time, the fixing method of clamping on a cable has poor stability. The wind is strong at high altitudes, and the air flow at high altitudes can easily cause the mobile inspection platform to tilt and flip, affecting subsequent normal inspections.

[0004] Therefore, it is necessary to invent a mobile testing platform for testing aging-resistant flame-retardant cables. Summary of the invention

[0005] To this end, the present invention provides a mobile inspection platform for detecting aging-resistant and flame-retardant cables. When the camera recognizes that the outer wall of the cable is damaged, a label tape is attached to the outer wall of the cable through a marking component to solve the problem that it is difficult for staff to determine the specific location of the damaged cable; then, through the detection sets and cameras arranged on the upper and lower sides of the two cables, and the flip sets and cameras that can be flipped to both sides, four parallel cables are photographed at the same time to solve the problem that the traditional mobile inspection platform needs to perform repeated movements of similar paths multiple times before it can detect multiple parallel cables; finally, by clamping multiple groups of clamping rollers on two adjacent parallel cables, and rotating the clamping rollers to drive the mobile inspection platform to move along the cables, the problem that the traditional fixing method has poor stability, the wind is strong at high altitudes, and the air flow at high altitudes easily drives the mobile inspection platform to tilt and flip is solved.

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0031] like Figure 1 - Figure 6 As shown, a mobile inspection platform for inspecting aging-resistant and flame-retardant cables in an embodiment of the first aspect of the present invention comprises a central axis 11 and a cable 4, two clamping plates 12 are rotatably installed at both ends of the central axis 11, and the two clamping plates 12 are arranged in an X-shaped overlapping manner, and fixed plates 13 are fixedly installed at both ends of the clamping plates 12, and clamping rollers 14 are rotatably installed on the side where the two clamping plates 12 are close to each other, and the clamping rollers 14 on the two overlapping clamping plates 12 can clamp the outer walls of two parallel cables 4, and a plurality of connecting plates 31 are fixedly installed between the clamping plates 12 at both ends of the central axis 11, and the connecting plates 31 are respectively arranged on the upper sides of the two cables 4 clamped by the clamping rollers 14. On the lower two sides, a detection sleeve 16 is fixedly installed on the side of the connecting plate 31 away from the cable 4, a camera 20 is installed on the side of the detection sleeve 16 close to the connecting plate 31, and a flip sleeve 19 is rotatably installed on the side of the detection sleeve 16 away from the connecting plate 31. The flip sleeve 19 can be flipped to one side to the outside of the adjacent cables 4 on the side where the two cables 4 clamped by the clamping rollers 14 are away from each other. After flipping, the flip sleeve 19 is close to the cable 4 and is installed with a camera 20. A marking component is installed on the connecting plate 31 above the cable 4. When the camera 20 recognizes that the outer wall of the cable 4 is damaged, the marking component can stick a label tape on the outer wall of the cable 4.

[0032] In the above embodiment, it should be noted that the camera 20 is used to collect video image information on the surface of the cable and transmit it to the receiving device, and the receiving device is used to receive the video image information collected by the camera 20 and display and play it, so that the staff can observe the surface state of the cable and find damaged cables 4 in time; when the camera 20 recognizes that the outer wall of the cable 4 is damaged, the marking component is used to stick a label on the outer wall of the cable 4, so that the staff can quickly determine the specific location of the damaged cable 4 when performing subsequent high-altitude maintenance operations, effectively shortening the high-altitude operation time and reducing the operation risk; by arranging on the upper and lower sides of the two cables 4 The detection set plate 16 and the camera 20, as well as the flip set plate 19 and the camera 20 that can be flipped to both sides, can simultaneously shoot four mutually parallel cables 4, so as to achieve the effect of detecting up to four mutually parallel cables, reduce multiple repeated movements of similar paths, and greatly improve the detection efficiency of multiple cables; the clamping roller 14 is made of rubber material, and multiple sets of clamping rollers 14 are clamped on two adjacent cables 4 that are parallel to each other, and the clamping rollers 14 are rotated to drive the mobile detection platform to move along the cable 4, so as to achieve the effect of improving the stability of the mobile detection platform, strengthen the resistance to high-altitude air flow disturbance, and enable it to perform detection work along the cable more stably. Example

[0033] like Figure 7 , Fig. 9 and Fig.10 As shown, a mobile inspection platform for aging-resistant flame-retardant cable inspection includes all the contents of Example 1. In addition, the marking component includes a winding roller 32, the winding roller 32 is rotatably installed at one end of the connecting plate 31 above the cable 4, and the outer wall of the winding roller 32 is wound with a marking tape 33. One end of the marking tape 33 is pulled out from the winding roller 32 and extends to the lower part of the middle of the connecting plate 31. The pulled-out end of the marking tape 33 is close to the surface of the cable 4. The marking component includes a first hydraulic rod 34, the first hydraulic rod 34 is fixedly installed in the middle of the connecting plate 31, and the lower end of the first hydraulic rod 34 is fixedly installed with a lower pressure plate 35 A second hydraulic rod 38 is fixedly installed on the top surface of the connecting plate 31 on the side of the first hydraulic rod 34 away from the winding roller 32, and a dividing cutter head 39 is fixedly installed on the lower end of the second hydraulic rod 38. The marking component includes a hydraulic cylinder 36, and the hydraulic cylinder 36 is fixedly installed on both sides of the connecting plate 31 between the first hydraulic rod 34 and the winding roller 32. A U-shaped push rod 37 is arranged below the hydraulic cylinder 36, and both ends of the U-shaped push rod 37 are upwardly inserted into the hydraulic cylinder 36 on both sides of the connecting plate 31. The lower ends of the hydraulic cylinder 36 and the U-shaped push rod 37 are inclined toward the side close to the winding roller 32, and the marking tape 33 passes through the middle of the U-shaped push rod 37.

[0034] In the above embodiment, it should be noted that one end 3 of the marking tape 33 on the winding roller 32 passes through the middle of the U-shaped push rod 37 and naturally droops to the bottom of the lower pressure plate 35. The marking tape 33 is usually in eye-catching colors such as red and yellow. The lower pressure plate 35 is made of rubber. When the camera 20 recognizes that the outer wall of the cable 4 is damaged, the lower pressure plate 35 is pushed downward by starting the first hydraulic rod 34 to squeeze the marking tape 33 so that one end of the marking tape 33 is bonded to the surface of the cable 4. Then the clamping roller 14 rotates and drives the clamping plate 12 As the connecting plate 31 moves relative to the surface of the cable 4, the marking tape 33 is continuously torn off the winding roller 32 and pasted on the surface of the cable 4. After a certain length of pasting, the second hydraulic rod 38 is started to push the dividing knife head 39 downward to cut off the marking tape 33. At the same time, the hydraulic cylinder 36 is started to drive the U-shaped push rod 37 to retract, driving the remaining marking tape 33 to separate from the surface of the cable 4, so as to achieve the effect of pasting the marking tape on the outer wall of the cable 4, which is convenient for the staff to quickly determine the specific location of the damaged cable 4. Example

[0035] like Figure 7 , Fig. 9 and Fig.10 As shown, a mobile inspection platform for aging-resistant and flame-retardant cable inspection includes all the contents of Example 2. In addition, the middle part of the clamping roller 14 is bent inward, and the clamping roller 14 can completely fit the surface of the cable 4. The end of the rotating shaft of the clamping roller 14 close to the central axis 11 is connected to the motor 15, and all the clamping rollers 14 rotate in the same direction. When the marking tape 33 is pasted on the cable 4, the clamping roller 14 can compact the pasted marking tape 33 to fit the surface of the cable 4.

[0036] In the above embodiment, it should be noted that the marking tape 33 initially pasted on the surface of the cable 4 is lifted up on both sides, and the clamping roller 14 is passed over the lifted marking tape 33 to achieve the effect of making the marking tape 33 tightly attached to the surface of the cable 4; the clamping roller 14 is driven to rotate by the starting motor 15 to achieve the effect of driving the mobile detection platform to move along the surface of the cable 4. Example

[0037] like Figure 1 - Figure 5 and Figure 7 , Figure 8As shown, a mobile inspection platform for inspecting aging-resistant and flame-retardant cables includes all the contents of Example 1. In addition, the inspection sleeve 16 and the flip sleeve 19 are both curved plate structures, and the cameras 20 on the inspection sleeve 16 and the flip sleeve 19 are both arranged at both ends of the inwardly bent side of the inspection sleeve 16 and the flip sleeve 19. Cameras 20 are arranged at four positions of the outer wall of the cable 4. A rotating support 17 is fixedly installed at one end of the outwardly arched side of the inspection sleeve 16 away from the central axis 11. The rotating support 17 is arranged on both sides of one end of the inspection sleeve 16. A rotating connecting plate 18 is rotatably installed on the rotating support 17. The end of the rotating connecting plate 18 away from the rotating support 17 is fixedly connected to the middle part of the outwardly arched side of the flip sleeve 19.

[0038] In the above embodiment, it should be noted that the detection sleeve 16 and the flip sleeve 19 are rotatably connected by rotating the support 17 and the rotating connecting plate 18. Two cameras 20 are installed on one detection sleeve 16 or the flip sleeve 19, so one detection sleeve 16 or the flip sleeve 19 can shoot a cable 4 in two directions. Example

[0039] like Figure 7 and Figure 8 As shown, a mobile testing platform for testing aging-resistant flame-retardant cables includes all the contents of Example 1. In addition, a first rotating seat 21 is arranged between the rotating supports 17 on both sides. The first rotating seat 21 is fixedly mounted on one end of the testing sleeve 16. A hydraulic push rod 22 is rotatably mounted on the first rotating seat 21. A second rotating seat 23 is rotatably mounted on the output end of the hydraulic push rod 22. The second rotating seat 23 is fixedly mounted on the side of the flip sleeve 19 that is arched outward and away from the central axis 11.

[0040] In the above embodiment, it should be noted that the effect of driving the flipping sleeve 19 to flip is achieved by starting the extended hydraulic push rod 22 , and the flipping angle of the flipping sleeve 19 can be determined by controlling the length of the hydraulic push rod 22 . Example

[0041] like Figure 5 - Figure 7 As shown, a mobile inspection platform for aging-resistant flame-retardant cable inspection includes all the contents of Example 1. In addition, rotating the two overlapping clamps 12 can drive the fixed plates 13 installed at both ends to deflect, and the end of the fixed plate 13 away from the clamp 12 can be deflected and connected, and the two connected fixed plates 13 can be fixedly connected by bolts.

[0042] In the above embodiment, it should be noted that the staff rotates the overlapping clamping plates 12 to clamp the clamping rollers 14 on the upper and lower sides of the two cables respectively, and then tightens the bolts to connect the fixing plates 13 to achieve the effect of fixing the mobile testing platform on the outer wall of the cable 4.

[0043] The use process of the present invention is as follows: the technicians in this field rotate the overlapping clamping plates 12 to clamp the clamping rollers 14 on the upper and lower sides of the two cables respectively, then tighten the bolts to connect the fixing plates 13, and fix the mobile detection platform on the outer wall of the cable 4, then start the extended hydraulic push rod 22, drive the flipping sleeve 19 to flip to the outside of the adjacent cable 4, start the motor 15 to drive the clamping rollers 14 to rotate, and drive the mobile detection platform to move along the surface of the cable 4. At the same time, the cameras 20 on the detection sleeve 16 and the flipping sleeve 19 simultaneously collect video image information of the four cables and transmit it to the receiving device. The receiving device receives the video image information collected by the camera 20 and displays and plays it. Then the staff observes the surface status of the cable. If the surface of the cable 4 is found to be damaged, the first hydraulic rod 34 is started to push the lower pressure plate 35 to squeeze the marking tape 33 downward, so that one end of the marking tape 33 is adhered to the surface of the cable 4, and then the clamping roller 14 rotates to drive the clamping plate 12 and the connecting plate 31 to move. With the relative movement of the connecting plate 31 and the surface of the cable 4, the marking tape 33 is continuously torn off the winding roller 32 and pasted on the surface of the cable 4. When a certain length is pasted, the second hydraulic rod 38 is started to push the dividing knife head 39 to cut off the marking tape 33 downward, and at the same time, the hydraulic cylinder 36 is started to drive the U-shaped push rod 37 to retract, driving the remaining marking tape 33 to separate from the surface of the cable 4, completing the pasting of the label tape on the outer wall of the cable 4, so that the subsequent maintenance personnel can quickly determine the specific location of the damaged cable 4.

[0044] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
