Description

Technical Field

[0001] This invention relates to the field of bridge inspection technology, specifically to a charging device for a track-mounted inspection robot. Background Technology

[0002] The track-mounted beam bottom inspection robot is an intelligent inspection robot used for inspecting structures such as bridges and railways. By carrying inspection instruments and sensors on a track, it can achieve comprehensive, efficient, and safe inspection of structures such as bridges and railways.

[0003] Currently, track-mounted beam bottom inspection vehicles are powered by diesel generators, lithium battery systems, or sliding contact lines. Diesel generators require fuel to generate electricity, which is then converted from three-phase power to DC power by an inverter to meet the power requirements of electrical appliances. Lithium battery systems provide direct power supply using batteries, while sliding contact line power supply requires the deployment of a large-area sliding contact line system; each has its own unique applicable scope.

[0004] In the field of automated inspection robots, charging piles are mainly used for charging. However, these charging devices are generally manual plug-in devices, which require manual assistance and are not very convenient in the field of bridge inspection. Summary of the Invention

[0005] This application provides a track-mounted inspection robot charging device, which can solve the problem that in the prior art, when an automatic inspection robot is charged, a manual plug-in device is used, which requires manual assistance and is not very convenient in the field of bridge inspection.

[0006] This invention provides a charging device for a track-mounted inspection robot, comprising:

[0007] A discharge output mechanism includes a mounting frame and two fixed sleeves spaced apart on the mounting frame. The mounting frame is fixedly mounted, and the fixed sleeves are provided with contact electrodes.

[0008] The charging mechanism includes a suspension bracket and two spaced-apart power receiving rods. The suspension bracket is used to connect to an inspection robot. The power receiving rods are connected to the suspension bracket via an adaptive adjustment component, which is used to adaptively adjust the direction of the power receiving rods so that the power receiving rods extend into the fixed sleeve.

[0009] In some alternative solutions, the suspension bracket includes: a support frame and two spaced-apart suspension frames. The support frame is used to connect with the inspection robot. The suspension frames are fixedly connected to the support frame. The suspension frames have a vertically oriented elongated hole. A suspension rod is provided on the outer side of the suspension frame, and the suspension rod is located above the elongated hole.

[0010] The adaptive adjustment component includes a balance block and two suspension springs. The balance block is located between the two suspension frames and is used to install the power receiving rod. The outer side of the balance block is provided with a rotating shaft extending out of the elongated hole. One end of the suspension spring is connected to the suspension rod, and the other end is connected to the rotating shaft.

[0011] In some alternative solutions, the rotating shaft is provided with two spaced-apart limit blocks, which are located on both sides of the suspension frame, and each limit block is provided with an elastic cup between it and the suspension frame.

[0012] In some alternative designs, the support frame and the counterweight are spaced apart. The support frame is equipped with a first proximity switch. The receiving rod includes an outer cylinder and a guide rod. The outer cylinder has a guide hole. The guide rod passes through the guide hole, with one end extending out of the counterweight and the other end extending out of the outer cylinder. The end extending out of the outer cylinder is equipped with a receiving electrode plate. The outer cylinder also has a spring cavity located at the end of the guide rod that extends out. The spring cavity is equipped with a return spring, which is sleeved on the guide rod and abuts against the receiving electrode plate. The end of the guide rod that extends out of the counterweight is equipped with a proximity switch trigger plate.

[0013] In some alternative designs, the end of the receiving pole is provided with a tapered electrode, and the end of the fixing sleeve is provided with a guide flare.

[0014] In some alternative solutions, the mounting bracket is further provided with two sliding sleeves corresponding to the fixed sleeve. The fixed sleeve and the sliding sleeve are respectively located on both sides of the mounting bracket. A slidable sliding rod is provided inside the sliding sleeve. One end of the sliding rod extends into the fixed sleeve and is provided with a contact electrode. A return spring is provided between the contact electrode and the mounting bracket. The return spring is sleeved on the sliding rod. The other end of the sliding rod extends out of the sliding sleeve and is provided with a proximity switch trigger block. A second proximity switch matching the proximity switch trigger block is provided on the mounting bracket.

[0015] In some alternative solutions, the proximity switch trigger block is provided with a guide hole, the mounting bracket is provided with a guide rod on the same side as the sliding sleeve, the second proximity switch is disposed on the guide rod, and the proximity switch trigger block is slidably connected to the guide rod through the guide hole.

[0016] In some alternative solutions, an insulating rubber plug is provided between the sliding rod and the contact electrode. The insulating rubber plug is sleeved on the sliding rod and its position is relatively fixed.

[0017] In some alternative solutions, the inner circumferential side of the fixed sleeve is provided with a plurality of clamping electrode plates, and the clamping electrode plates are provided with guide blocks on both sides connected to the fixed sleeve. The clamping electrode plates are connected to the insulating rubber plug through a transmission assembly. When the fixed sleeve moves, the insulating rubber plug drives the clamping electrode plates to move axially between the two guide blocks along the fixed sleeve through the transmission assembly, and clamps the conical electrode.

[0018] In some alternative embodiments, the transmission assembly includes:

[0019] A rotating bracket is connected to the mounting bracket;

[0020] The lever plate has its middle part rotatably connected to the rotating bracket, one end of which is connected to the insulating rubber plug via a first connecting rod, and the other end of which is connected to the clamping electrode plate.

[0021] The beneficial effects of the technical solution provided in this application include: when the inspection robot walks to the discharge output mechanism, the adaptive adjustment component adaptively adjusts the direction of the receiving rod so that the receiving rod extends into the fixed sleeve and abuts against the contact electrode in the fixed sleeve, thereby connecting the energy storage device of the inspection robot, realizing automatic charging of the inspection robot, and improving the ease of use of the inspection robot.

[0022] In other preferred embodiments, the suspension frame has an elongated hole, and the outer side of the balance block has a pivot extending out of the elongated hole. The suspension spring is connected to the pivot extending out of the elongated hole of the balance block. Two current-receiving rods are mounted on the balance block, which can move up and down to adjust the position of the current-receiving rods so that they extend into the fixed sleeve and abut against the contact electrode inside the fixed sleeve. When the contact electrode is pushed back by the current-receiving rod, the return spring is compressed, and the insulating rubber plug and sliding rod are pushed and moved towards the mounting frame. The movement of the insulating rubber plug pushes one end of the lever plate through the first connecting rod, causing one end of the lever plate to rotate towards the mounting frame. Since the middle of the lever plate is rotatably connected to the U-shaped frame, the other end of the lever plate rotates away from the mounting frame, thereby clamping the conical electrode and forming a more stable contact connection.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0033] like Figures 1-6As shown, the present invention provides a charging device for a track-type inspection robot, comprising: a discharge output mechanism 1 and a charging mechanism 2. The discharge output mechanism 1 includes a mounting frame 11 and two fixed sleeves 12 spaced apart on the mounting frame 11. The mounting frame 11 is fixedly mounted, and the fixed sleeves 12 contain contact electrodes 13. The charging mechanism 2 includes a suspension bracket 21 and two spaced-apart power receiving rods 22. The suspension bracket 21 is used to connect to the inspection robot, and the power receiving rods 22 are connected to the suspension bracket 21 via an adaptive adjustment component 23. The adaptive adjustment component 23 is used to adaptively adjust the direction of the power receiving rods 22 so that the power receiving rods 22 extend into the fixed sleeves 12.

[0034] When using the track-type inspection robot charging device, the mounting frame 11 is fixedly installed, the contact electrode 13 is connected to the mains power, the suspension bracket 21 is connected to the inspection robot, and the power receiving rod 22 is connected to the suspension bracket 21 through the adaptive adjustment component 23 and connected to the power storage device of the inspection robot. When the inspection robot walks to the discharge output mechanism 1, the adaptive adjustment component 23 adaptively adjusts the direction of the power receiving rod 22 so that the power receiving rod 22 extends into the fixed sleeve 12 and abuts against the contact electrode 13 inside the fixed sleeve 12, thereby connecting to the power storage device of the inspection robot, realizing automatic charging of the inspection robot, and improving the ease of use of the inspection robot.

[0035] like Figure 5 and Figure 6 As shown, in some optional embodiments, the suspension bracket 21 includes: a support frame 211 and two spaced-apart suspension brackets 212. The support frame 211 is used to connect with the inspection robot; the suspension brackets 212 are fixedly connected to the support frame 211, and the suspension brackets 212 are provided with a vertically oriented elongated hole 2121. A suspension rod 213 is provided on the outer side of the suspension brackets 212, and the suspension rod 213 is located above the elongated hole 2121; the adaptive adjustment component 23 includes a balance block 231 and two suspension springs 232. The balance block 231 is located between the two suspension brackets 212 and is used to install the power receiving rod 22. A rotating shaft 233 extending out of the elongated hole 2121 is provided on the outer side of the balance block 231. One end of the suspension spring 232 is connected to the suspension rod 213, and the other end is connected to the rotating shaft 233.

[0036] In this embodiment, the balance block 231 is suspended on the suspension frame 212 by two suspension springs 232. When the current receiving rod 22 is not aligned properly during the process of extending into the fixed sleeve 12, since the suspension frame 212 is provided with an elongated hole 2121 and the outside of the balance block 231 is provided with a rotating shaft 233 extending out of the elongated hole 2121, the suspension spring 232 is connected to the rotating shaft of the balance block 231 extending out of the elongated hole 2121. The two current receiving rods 22 are installed on the balance block 231, and the balance block 231 can move up and down to adjust the position of the current receiving rod 22 so that the current receiving rod 22 extends into the fixed sleeve 12 and abuts against the contact electrode 13 inside the fixed sleeve 12.

[0037] In this example, the suspension bracket 212 is a plate-shaped component with a vertically oriented elongated hole 2121, which allows the balance block 231 to move up and down to align the current receiving rod 22 mounted on the balance block 231 with the fixed sleeve 12. The balance block 231 is used to maintain the balance of the current receiving rod 22 so that the current receiving rod 22 remains basically horizontal.

[0038] In some optional embodiments, the rotating shaft 233 is provided with two spaced-apart limiting blocks 234, which are located on both sides of the suspension frame 212 respectively, and each limiting block 234 is provided with an elastic cup 235 between it and the suspension frame 212.

[0039] In this embodiment, two spaced limiting blocks 234 are arranged on the rotating shaft 233 and located on both sides of the suspension frame 212. An elastic cup 235 is provided between the limiting blocks 234 and the suspension frame 212. Since the elastic cup 235 has the elasticity to move, it can be compressed adaptively. Therefore, the balance block 231 can swing adaptively in the horizontal direction.

[0040] In some optional embodiments, the support frame 211 and the balance block 231 are spaced apart. The support frame 211 is provided with a first proximity switch 24. The power receiving rod 22 includes an outer cylinder 221 and a guide rod 222. The outer cylinder 221 is provided with a guide hole. The guide rod 222 passes through the guide hole, with one end extending out of the balance block 231 and the other end extending out of the outer cylinder 221. One end extending out of the outer cylinder 221 is provided with a receiving electrode plate 223. The outer cylinder 221 is also provided with a spring cavity located at the end of the guide rod 222. The spring cavity is provided with a reset spring 224, which is sleeved on the guide rod 222 and abuts against the receiving electrode plate 223. One end of the guide rod 222 extending out of the balance block 231 is provided with a proximity switch trigger plate 25.

[0041] In this embodiment, the guide rod 222 can slide inside the outer cylinder 221 and pass through the balance block 231. A spring cavity is also provided inside the outer cylinder 221, and a reset spring 224 is provided inside the spring cavity, which is sleeved on the guide rod 222 and abuts against the receiving electrode plate 223, providing a certain restoring force for the guide rod 222. This allows the guide rod 222 to partially extend out of the outer cylinder 221 in its natural state. When the inspection robot moves, the receiving electrode plate 223 at the end of the guide rod 222 is compressed with the contact electrode 13, which allows the proximity switch trigger plate 25 on the guide rod 222 to extend towards the support frame 211. This causes the proximity switch trigger plate 25 to approach the first proximity switch 24, thereby triggering the electrical connection between the contact electrode 13 and the inspection robot's energy storage device. This reduces the possibility of the inspection robot's energy storage device discharging externally when it is not charging, as the contact electrode 13 on the guide rod 222 is not connected to the inspection robot's energy storage device.

[0042] like Figures 2 to 4 As shown, in some optional embodiments, the end of the receiving rod 22 is provided with a tapered electrode 26, and the end of the fixing sleeve 12 is provided with a guide flare 14.

[0043] In this embodiment, the large diameter of the guide horn 14 faces the direction of the power receiving rod 22, and the small diameter of the conical electrode 26 faces the direction of the guide horn 14. This arrangement makes it easier for the conical electrode 26 to be guided into the guide horn 14, and, in conjunction with the adaptive adjustment component 23, it makes it easier for the conical electrode 26 to enter the outer cylinder 221. In this example, the conical electrode 26 is sleeved on the outside of the guide rod 222 of the power receiving rod 22 and connected to it, moving synchronously with the guide rod 222. It is also electrically connected to the power storage device of the inspection robot and is controlled by the proximity switch trigger plate 25 and the first proximity switch 24.

[0044] In some optional embodiments, the mounting bracket 11 is also provided with two sliding sleeves 15 corresponding to the fixed sleeve 12. The fixed sleeve 12 and the sliding sleeve 15 are respectively located on both sides of the mounting bracket 11. The sliding sleeve 15 is provided with a slidable sliding rod 16. One end of the sliding rod 16 extends into the fixed sleeve 12 and is provided with a contact electrode 13. A return spring 19 is provided between the contact electrode 13 and the mounting bracket 11. The return spring 19 is sleeved on the sliding rod 16. The other end of the sliding rod 16 extends out of the sliding sleeve 15 and is provided with a proximity switch trigger block 17. The mounting bracket 11 is provided with a second proximity switch 18 that matches the proximity switch trigger block 17.

[0045] In this embodiment, the fixed sleeve 12 and the sliding sleeve 15 are coaxially arranged. The inner diameter of the fixed sleeve 12 is larger than the inner diameter of the sliding sleeve 15. The diameter of the sliding rod 16 is adapted to the diameter of the sliding sleeve 15, allowing it to slide within the sliding sleeve 15. A return spring 19 is provided between the contact electrode 13 and the mounting bracket 11. When the return spring 19 is in its natural state, the charging device connected to the contact electrode 13 is disconnected from the mains power. When the contact electrode 13 is pushed by the current receiving rod 22 and the return spring 19 is compressed, the sliding rod 16 is pushed, causing the sliding rod 16 to move away from the suspension bracket 21. This changes the relative state between the proximity switch trigger block 17 and the second proximity switch 18, thereby connecting the charging device connected to the contact electrode 13 to the mains power. This design avoids connecting the charging device connected to the contact electrode 13 to the mains power during non-charging times, preventing power loss or safety hazards.

[0046] In this scheme, when the proximity switch trigger block 17 and the second proximity switch 18 are far apart by a set distance, the charging device connected to the contact electrode 13 is connected to the mains power. When the proximity switch trigger block 17 and the second proximity switch 18 are close to each other to a set distance, the charging device connected to the contact electrode 13 is disconnected from the mains power. In other embodiments, the opposite control logic can also be used to achieve a basically the same effect. The specific scheme can be designed according to the actual situation.

[0047] In some optional embodiments, the proximity switch trigger block 17 is provided with a guide hole, the mounting bracket 11 is provided with a guide rod 110 on the same side as the sliding sleeve 15, the second proximity switch 18 is provided on the guide rod 110, and the proximity switch trigger block 17 is slidably connected to the guide rod 110 through the guide hole.

[0048] In this embodiment, the proximity switch trigger block 17 is fixedly connected to the sliding rod 16, and the mounting bracket 11 is fixedly connected to the guide rod 110. A guide hole is provided on the proximity switch trigger block 17, and the proximity switch trigger block 17 is slidably connected to the guide rod 110 through the guide hole. This can prevent the sliding rod 16 from rotating when it is pushed axially by the power receiving rod 22, and at the same time, it can prevent the proximity switch trigger block 17 from rotating, thereby causing the matching position between the proximity switch trigger block 17 and the second proximity switch 18 to change, and thus failing to play a good role in controlling the connection or disconnection.

[0049] In some optional embodiments, an insulating rubber plug 111 is provided between the sliding rod 16 and the contact electrode 13. The insulating rubber plug 111 is sleeved on the sliding rod 16 and its position is relatively fixed.

[0050] In this embodiment, both the contact electrode 13 and the insulating rubber plug 111 are fixed relative to the sliding rod 16. The insulating rubber plug 111 is provided between the sliding rod 16 and the contact electrode 13 to prevent the contact electrode 13 from contacting the mounting bracket 11, which could lead to leakage to the mounting bracket 11 and pose a safety risk.

[0051] In some optional embodiments, a plurality of clamping electrode plates 112 are provided circumferentially on the inner side of the fixed sleeve 12. Guide blocks 113 connected to the fixed sleeve 12 are provided on both sides of the clamping electrode plates 112. The clamping electrode plates 112 are connected to the insulating rubber plugs 111 through a transmission assembly. When the fixed sleeve 12 moves, the insulating rubber plugs 111 drive the clamping electrode plates 112 to move axially between the two guide blocks 113 through the transmission assembly, and clamp the conical electrode 26.

[0052] In this embodiment, the clamping electrode plate 112 is arranged along the axial direction of the fixed sleeve 12. The contact electrode 13 and the insulating rubber plug 111 are cylindrical, and their diameters are smaller than the diameter of the fixed sleeve 12. The clamping electrode plate 112 is disposed in the gap between the fixed sleeve 12 and the contact electrode 13. When the fixed sleeve 12 moves, the insulating rubber plug 111 drives the clamping electrode plate 112 to move axially between the two guide blocks 113 along the fixed sleeve 12 via the transmission assembly, and clamps the tapered electrode 26. This design allows for more sufficient contact between the power supply end and the power receiving end of the entire charging device, avoiding the situation where poor contact occurs when only the contact electrode 13 and the receiving electrode plate 223 at the end of the receiving rod 22 are used.

[0053] In this example, two guide blocks 113 are arranged on both sides of the clamping electrode plate 112, and are also arranged along the axial direction of the fixed sleeve 12. They are used to restrict the clamping electrode plate 112 to move only in the axial direction and prevent the clamping electrode plate 112 from moving in the radial direction of the fixed sleeve 12.

[0054] In addition, the clamping electrode 112 is also controlled by the relative positional relationship between the proximity switch trigger block 17 and the second proximity switch 18. Specifically, it controls the charging device connected to the clamping electrode 112 to be connected to or disconnected from the mains power, and its control method is synchronized with the connection or disconnection of the charging device connected to the mains power by the contact electrode 13.

[0055] like Figure 5 As shown, in some optional embodiments, the transmission assembly includes a rotating bracket 114 and a lever plate 115. The rotating bracket 114 is connected to the mounting bracket 11; the middle part of the lever plate 115 is rotatably connected to the rotating bracket 114, one end of which is connected to the insulating rubber plug 111 via a first connecting rod, and the other end is connected to the clamping electrode plate 112.

[0056] In this embodiment, the rotating bracket 114 includes a U-shaped frame and a connecting frame. The connecting frame is connected to the closed end of the U-shaped frame. The opening of the U-shaped frame faces the power receiving rod 22. The lever plate 115 is disposed inside the U-shaped frame, and the middle part of the lever plate 115 is rotatably connected to the U-shaped frame to form a lever. One end of the lever plate 115 is connected to the insulating rubber plug 111 through the first connecting rod, and the other end is connected to the end of the clamping electrode plate 112. The other end of the clamping electrode plate 112 extends out of the contact electrode 13 in the axial direction of the fixed sleeve 12. When the contact electrode 13 is compressed by the push return spring 19 of the current receiving rod 22, the insulating rubber plug 111 and the sliding rod 16 are pushed and moved towards the mounting frame 11. The movement of the insulating rubber plug 111 will push one end of the lever plate 115 through the first connecting rod, causing one end of the lever plate 115 to rotate towards the mounting frame 11. Since the middle part of the lever plate 115 is rotatably connected to the U-shaped frame, the other end of the lever plate 115 will rotate away from the mounting frame 11, thereby clamping the conical electrode 26 and forming a more stable contact connection.

[0057] like Figure 1 , Figure 2 and Figure 4 As shown, in addition, a discharge protection shell 116 is provided on the outside of the entire discharge output mechanism 1. In the natural state of the return spring 19, the discharge protection shell 116 covers the contact electrode 13 and the guide horn 14. A charging protection shell 27 is also provided on the outside of the entire charging mechanism 2. In the natural state of the reset spring 224, the charging protection shell 27 covers the receiving electrode plate 223. When the return spring 19 and the reset spring 224 are compressed, the charging protection shell 27 covers the guide horn 14, and the end of the discharge protection shell 116 covers the outside of the charging protection shell 27.

[0058] In summary, when the inspection robot moves to the discharge output mechanism 1, the adaptive adjustment component 23 adaptively adjusts the direction of the power receiving rod 22 so that the power receiving rod 22 extends into the fixed sleeve 12 and abuts against the contact electrode 13 inside the fixed sleeve 12, thereby connecting the power storage device of the inspection robot, realizing automatic charging of the inspection robot, and improving the ease of use of the inspection robot.

[0059] Since the suspension frame 212 is provided with an elongated hole 2121 and the outer side of the balance block 231 is provided with a rotating shaft 233 extending out of the elongated hole 2121, the suspension spring 232 is connected to the rotating shaft of the balance block 231 extending out of the elongated hole 2121, and two electric rods 22 are installed on the balance block 231. The balance block 231 can move up and down to adjust the position of the electric rods 22 so that the electric rods 22 extend into the fixed sleeve 12 and abut against the contact electrode 13 inside the fixed sleeve 12.

[0060] When the contact electrode 13 is compressed by the push return spring 19 of the current receiving rod 22, the insulating rubber plug 111 and the sliding rod 16 are pushed and moved towards the mounting frame 11. The movement of the insulating rubber plug 111 will push one end of the lever plate 115 through the first connecting rod, causing one end of the lever plate 115 to rotate towards the mounting frame 11. Since the middle part of the lever plate 115 is rotatably connected to the U-shaped frame, the other end of the lever plate 115 will rotate away from the mounting frame 11, thereby clamping the conical electrode 26 and forming a more stable contact connection.
