Description

Technical Field

[0001] This invention relates to the field of line inspection technology, specifically a railway power supply line inspection device. Background Technology

[0002] Railway power supply lines are a crucial component of the power supply system, responsible for transmitting and distributing electrical energy. Traditionally, the inspection of transmission lines is done manually, step by step. Furthermore, transmission lines traverse various complex terrains, making manual labor extremely demanding and inefficient. Currently, drones are being used for power line inspections, significantly reducing the workload for workers.

[0003] Railway power supply lines are long, and the workload for their maintenance and inspection is substantial. Manual inspection requires significant manpower and resources. Therefore, while machine inspection is used, current technology requires ground personnel to observe the damage to the power lines through ground terminals. When a power line breaks, personnel need to brake the railway power supply line inspection equipment in a timely manner. This reliance on human control is high, and it is not possible to automatically brake the equipment when a power line breaks, which could easily cause the equipment to fall off the line. Summary of the Invention

[0004] The purpose of this invention is to provide a railway power supply line inspection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A railway power supply line inspection device includes a connecting frame and further includes:

[0007] Two sets of drive structures are installed on a connecting frame. Each drive structure includes a frame fixedly connected to the connecting frame, a wire-carrying mechanism fixedly installed on the frame, an elastic braking mechanism installed on the frame, and a linkage drive mechanism connected to the elastic braking mechanism. The linkage drive mechanism includes a lifting part connected to the frame, a first pressure roller rotatably installed on the lifting part, and a drive part connected to the lifting part. The drive part includes a first motor fixedly connected to the lifting part, a first clutch disc fixedly installed on the output shaft of the first motor, a second clutch disc movably connected to the first clutch disc and connected to the elastic braking mechanism, a sleeve fixedly connected to the second clutch disc, and a prism slidably connected to the sleeve and coaxially fixedly connected to the first pressure roller.

[0008] The camera unit is fixedly connected to the connecting bracket.

[0009] As a further improvement of the present invention: the camera unit includes a bracket fixedly connected to the connecting frame, and two sets of first cameras are fixedly installed on the bracket.

[0010] As a further improvement of the present invention: the wire-carrying mechanism includes a wheel frame fixedly connected to the frame, and a second pressure wheel is rotatably mounted on the wheel frame.

[0011] As a further improvement of the present invention: the elastic braking mechanism includes a slide bracket fixedly connected to the frame, an elastic telescopic frame fixedly installed on the frame, a rack fixedly installed on the elastic telescopic frame, a sliding pressure frame fixedly connected to the rack, a gear meshing with the rack rotatably connected to the slide bracket, a swing frame fixedly connected to the gear coaxially, a sliding sleeve slidably connected to the swing frame, a linkage frame fixedly connected to the sliding sleeve and rotatably connected to the second clutch disc, the linkage frame slidably connected to the lifting part, and a friction frame fixedly connected to the linkage frame.

[0012] As a further improvement of the present invention: friction rings adapted to the friction frame are fixedly installed on both the first pressure roller and the second pressure roller.

[0013] As a further improvement of the present invention: the lifting part includes a limiting frame fixedly connected to the frame, a second motor fixedly installed on the limiting frame, a lead screw fixedly connected to the output shaft of the second motor, a lifting frame slidably connected to the lead screw and the limiting frame, the lifting frame fixedly connected to the first motor, the lifting frame slidably connected to the linkage frame, and the lifting frame rotatably connected to the first pressure roller.

[0014] As a further improvement of the present invention: a balancing block is fixedly installed on the connecting frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The elastic braking mechanism is clamped onto the wire. The lifting part drives the first pressure roller to press the wire, so that the wire is clamped by the first pressure roller and the wire carrying mechanism. At this time, only the first motor in the forward direction of this inspection equipment is powered. The first motor drives the first clutch disc to rotate. The first clutch disc drives the sleeve to rotate through the second clutch disc. The sleeve drives the first pressure roller to rotate through the prism, so that the drive structure drives the connecting frame to move along the wire. During this time, the camera unit performs video recording on the outside of the wire. When the wire breaks, as this inspection equipment moves, the elastic braking mechanism first disengages from the wire. When the elastic braking mechanism disengages from the wire, it drives the second clutch disc to disengage from the first clutch disc. The second clutch disc drives the sleeve to slide along the prism, thereby disconnecting the power connection between the first motor and the first pressure roller, and the elastic braking mechanism performs braking operation on the first pressure roller. When the present invention moves along the power line, if the power line breaks, the first pressure roller is braked by the elastic braking mechanism, and the power connection between the first motor and the first pressure roller is disconnected. This allows for automated braking without the personnel noticing the breakage, preventing the present invention from falling from a height due to the broken power line. Attached Figure Description

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Example 1, see Figures 1-5 As shown, a railway power supply line inspection device includes a connecting frame 1, on which a remote communication module for information transmission is fixedly installed, and further includes:

[0025] Two sets of drive structures 2 are installed on the connecting frame 1. Each drive structure 2 includes a frame 3 fixedly connected to the connecting frame 1. A second camera is fixedly installed on the frame 3. A wire-carrying mechanism 4 is fixedly installed on the frame 3. An elastic braking mechanism 5 is installed on the frame 3. The elastic braking mechanism 5 is connected to a linkage drive mechanism 6. The linkage drive mechanism 6 includes a lifting part 7 connected to the frame 3. A first pressure roller 8 is rotatably installed on the lifting part 7. The lifting part 7 is connected to a drive part 9. The drive part 9 includes a first motor 10 fixedly connected to the lifting part 7. A first clutch disc 11 is fixedly installed on the output shaft of the first motor 10. A second clutch disc 12 connected to the elastic braking mechanism 5 is movably connected to the first clutch disc 11. A sleeve 13 is fixedly connected to the second clutch disc 12. A prism 14 coaxially fixedly connected to the first pressure roller 8 is slidably connected to the sleeve 13. A first spring is installed between the sleeve 13 and the prism 14.

[0026] The camera unit 15 is fixedly connected to the connecting bracket 1.

[0027] The elastic braking mechanism 5 is clamped onto the wire. The lifting part 7 drives the first pressure roller 8 to press the wire, so that the wire is clamped by the first pressure roller 8 and the wire carrying mechanism 4. At this time, only the first motor 10 in the forward direction of this inspection equipment is powered. The first motor 10 drives the first clutch disc 11 to rotate. The first clutch disc 11 drives the sleeve 13 to rotate through the second clutch disc 12. The sleeve 13 drives the first pressure roller 8 to rotate through the prism 14, so that the drive structure 2 drives the connecting frame 1 to move along the wire. During this time, the camera part 15 performs camera operation on the outside of the wire. When the wire breaks, as this inspection equipment moves, the elastic braking mechanism 5 first disengages from the wire. When the elastic braking mechanism 5 disengages from the wire, the elastic braking mechanism 5 drives the second clutch disc 12 to disengage from the first clutch disc 11. The second clutch disc 12 drives the sleeve 13 to slide along the prism 14, thereby disconnecting the power connection between the first motor 10 and the first pressure roller 8, and the elastic braking mechanism 5 performs braking operation on the first pressure roller 8. When the present invention moves along the power line, if the power line breaks, the first pressure roller 8 is braked by the elastic braking mechanism 5, and the power connection between the first motor 10 and the first pressure roller 8 is disconnected. This allows for automated braking without the personnel noticing the breakage, preventing the present invention from falling from a height due to the broken power line.

[0028] In one embodiment, the camera unit 15 includes a hanger 16 fixedly connected to the connecting frame 1, and two sets of first cameras 17 are fixedly mounted on the hanger 16. The first cameras 17 are used to photograph the outer surface of the wire, and the images captured by the first cameras 17 are transmitted to the control terminal of the ground personnel through a remote communication module, thereby facilitating the ground operators to obtain images of the wire.

[0029] In one embodiment, the wire-carrying mechanism 4 includes a wheel frame 18 fixedly connected to the frame 3, and a second pressure roller 19 is rotatably mounted on the wheel frame 18. The second pressure roller 19 is used to carry the wire.

[0030] In one embodiment, the elastic braking mechanism 5 includes a slide bracket 20 fixedly connected to the frame 3. An elastic telescopic frame 21 is fixedly installed on the frame 3. The elastic telescopic frame 21 includes a driven telescopic frame connected to the frame 3. A return spring is installed inside the driven telescopic frame. A rack 22 is fixedly installed on the elastic telescopic frame 21. A sliding pressure frame 34 is fixedly connected to the rack 22. A gear 23 meshing with the rack 22 is rotatably connected to the slide bracket 20. A swing frame 24 is coaxially fixedly connected to the gear 23. A sliding sleeve 25 is slidably connected to the swing frame 24. A linkage frame 26 rotatably connected to the second clutch disc 12 is fixedly connected to the sliding sleeve 25. The linkage frame 26 is slidably connected to the lifting part 7. A friction frame 27 is fixedly connected to the linkage frame 26. The elastic telescopic frame 21 drives the sliding pressure frame 34 to press on the wire via the rack 22. At this time, the sliding bracket 20 works with the sliding pressure frame 34 to clamp the wire. When the wire breaks, as the sliding pressure frame 34 moves to the broken end of the wire, the rack 22 drives the sliding pressure frame 34 to press towards the sliding bracket 20 under the drive of the elastic telescopic frame 21. At this time, the gear 23 is driven by the moving rack 22. The gear 23 drives the swing frame 24 to rotate. The swing frame 24 drives the sliding sleeve 25 to move. The sliding sleeve 25 drives the linkage frame 26 to move. The linkage frame 26 drives the friction frame 27 to move towards the first pressure roller 8, thereby braking the first pressure roller 8. The linkage frame 26 also drives the second clutch disc 12 away from the first clutch disc 11.

[0031] In one embodiment, friction rings 28 adapted to the friction frame 27 are fixedly installed on both the first pressure roller 8 and the second pressure roller 19. By installing friction rings 28 on the first pressure roller 8 and the second pressure roller 19, the friction frame 27 is prevented from scratching the first pressure roller 8 and the second pressure roller 19.

[0032] In one embodiment, the lifting part 7 includes a limiting frame 29 fixedly connected to the frame 3. A second motor 30 is fixedly mounted on the limiting frame 29. A lead screw 31 is fixedly connected to the output shaft of the second motor 30. The lead screw 31 is threadedly connected to a lifting frame 32 slidably connected to the limiting frame 29. The lifting frame 32 is fixedly connected to a first motor 10, slidably connected to a linkage frame 26, and rotatably connected to a first pressure roller 8. The second motor 30 drives the lead screw 31 to rotate, and the lead screw 31 drives the lifting frame 32 to slide along the limiting frame 29, so that the first motor 10, the linkage frame 26, and the first pressure roller 8 move together with the lifting frame 32.

[0033] Example 2, based on Example 1, see [link / reference] Figure 1 and Figure 2 A balancing block 33 is fixedly installed on the connecting frame 1. By fixing the balancing block 33 on the connecting frame 1, the weight balancing operation of the present invention is performed.
