Abstract

[0001] The present invention relates to the technical field of special robots, and in particular to a circuit breaker opening and closing device and a robot. Background Art
[0002] In the daily power supply tasks of the power distribution room, if a power failure occurs, the staff usually need to manually operate the switch handle of the circuit breaker to disconnect it first, and then manually close it to restore power supply after the fault is eliminated. This process is called the opening and closing operation of the circuit breaker.
[0003] At present, with the development of technology, the research and development of distribution room inspection robots is advancing rapidly. Robots can replace staff to perform operations to reduce manual labor intensity and have higher safety. However, in the opening and closing operations of circuit breakers, since the circuit breaker handle usually requires a certain torque to be turned, if the end gripper of the current distribution room inspection robot is used to turn the circuit breaker handle, the end gripper usually cannot provide enough torque, but will cause the end gripper to bear the reaction force generated when turning, making it difficult for the robot as a whole to remain stable. Therefore, in the event of a power failure, the opening and closing operations of the circuit breaker still need to rely on manual labor, which is inefficient and poses certain safety risks.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0048] like Figure 1 As shown, this embodiment provides a robot, including a mobile vehicle 100, a robot base 200, a robot body 300 and a circuit breaker opening and closing device 400.
[0049] The robot base 200 is installed on the mobile vehicle 100 , the robot body 300 is installed on the robot base 200 , and the circuit breaker opening and closing device 400 is installed at the end of the robot body 300 .
[0050] Specifically, the mobile vehicle 100 may be an AGV (Automated Guided Vehicle), that is, an automatic guided vehicle. The robot body 300 may be composed of a six-axis robotic arm, and the circuit breaker opening and closing device 400 is installed at the end of the robotic arm.
[0051] like Figure 1 to Figure 5 As shown, the circuit breaker opening and closing device 400 provided in this embodiment includes a frame 10, an adsorption mechanism 20 and an operating mechanism 30.
[0052] The adsorption mechanism 20 includes a first driving component 1 and a suction cup 2. The first driving component 1 is arranged on the frame 10. The suction cup 2 is connected to the first driving component 1. The suction cup 2 has an adsorption state and a desorption state. The first driving component 1 is configured to drive the suction cup 2 to switch between the adsorption state and the desorption state so that the suction cup 2 can be adsorbed on the outer surface of the distribution cabinet or detached from the outer surface of the distribution cabinet.
[0053] The operating mechanism 30 includes a second drive component 3 and a toggle member 4. The second drive component 3 is arranged on the frame 10. The toggle member 4 is connected to the second drive component 3. The second drive component 3 can drive the toggle member 4 to move together. The toggle member 4 is configured to toggle the circuit breaker handle on the outer surface of the distribution cabinet when the suction cup 2 is adsorbed on the outer surface of the distribution cabinet, so that the circuit breaker handle can be opened or closed.
[0054] In specific implementation, the circuit breaker opening and closing device 400 is first brought close to the outer surface of the distribution cabinet, and then the adsorption mechanism 20 is started, so that the suction cup 2 is switched to the adsorption state and adsorbed on the outer surface of the distribution cabinet, and the circuit breaker opening and closing device 400 is in the adsorption state as a whole. Then the operating mechanism 30 is started, and the second driving component 3 drives the toggle member 4 to toggle the circuit breaker handle located on the outer surface of the distribution cabinet to open or close the circuit breaker.
[0055] The circuit breaker opening and closing device 400 provided in this embodiment uses the adsorption mechanism 20 to make the suction cup 2 adsorb on the outer surface of the distribution cabinet to form a stable support structure. In this state, when the operating mechanism 30 toggles the circuit breaker handle, the adsorption force can be used to effectively offset the reaction force generated by the toggling handle, avoiding the displacement of the circuit breaker opening and closing device 400 due to the reaction force, thereby significantly improving the stability and reliability of the circuit breaker opening and closing operation. When the robot equipped with the circuit breaker opening and closing device 400 is used, the reaction force cannot have a significant impact on the robot, avoiding the displacement or instability of the robot during the circuit breaker opening and closing process, while reducing the robot's dependence on high torque and reducing the requirements for the strength of the end gripper structure.
[0056] like Figure 4 As shown, in some embodiments, the first driving component 1 includes an electric push rod 11 and a suction cup pull rod 12, the electric push rod 11 is connected to the frame 10, one end of the suction cup pull rod 12 is connected to the movable end of the electric push rod 11, and the other end of the suction cup pull rod 12 is connected to the suction cup 2, and the extension and retraction of the electric push rod 11 can drive the suction cup pull rod 12 to move, thereby driving the suction cup 2 to sink or bulge.
[0057] Specifically, Figure 4 Take the position in the figure as an example, when the movable end of the electric push rod 11 retracts to the right, the suction cup pull rod 12 is driven to move to the right, and the pulling force transmitted to the suction cup 2 can make the inside of the suction cup 2 concave, forming a vacuum, generating suction, so that the suction cup 2 can be adsorbed on the outer surface of the distribution cabinet. When the opening and closing task is completed, the movable end of the electric push rod 11 extends to the left, causing the inside of the suction cup 2 to bulge to the left, the suction of the suction cup 2 disappears, and the circuit breaker opening and closing device 400 is completely separated from the outer surface of the distribution cabinet.
[0058] Through such a setting, the telescopic action of the electric push rod 11 can accurately control the movement of the suction cup pull rod 12, thereby realizing efficient switching of the suction cup 2 between the recessed and protruding states, ensuring that the suction cup 2 can quickly form and release the adsorption force, greatly improving the response speed of the opening and closing operations.
[0059] like Figure 4 As shown, in some embodiments, the frame 10 includes a top plate 101, a bottom plate 102 and a connecting column 103, and the connecting column 103 is connected between the top plate 101 and the bottom plate 102. The top plate 101 is fixed with a mounting seat 5, the fixed end of the electric push rod 11 is mounted on the mounting seat 5, the movable end of the electric push rod 11 is movably penetrated through the top plate 101 and can extend into the gap between the top plate 101 and the bottom plate 102, the suction cup 2 is arranged on the side of the bottom plate 102 away from the top plate 101, the end of the suction cup pull rod 12 away from the suction cup 2 is configured to be penetrated through the bottom plate 102 and extend into the gap between the top plate 101 and the bottom plate 102, and the end of the suction cup pull rod 12 away from the suction cup 2 is connected to the movable end of the electric push rod 11.
[0060] Through such a configuration, the frame 10 forms a stable frame structure, which can provide sufficient support strength during the opening and closing process of the circuit breaker. At the same time, the mounting seat 5 on the top plate 101 provides a fixed mounting point for the electric push rod 11, making the fixed end of the electric push rod 11 more stable.
[0061] like Figure 2 As shown, in some embodiments, a quick-change mechanism 40 is provided on the top plate 101 , and the quick-change mechanism 40 is fixed to the top plate 101 by screws. The quick-change mechanism 40 can cooperate with the quick-change mechanism at the end of the robot body 300 to realize the rapid replacement of the circuit breaker opening and closing device 400 .
[0062] like Figure 3 and Figure 4As shown, in some embodiments, two suction cups 2 are provided, and the suction cup pull rods 12 are provided one by one with the suction cups 2, and a transmission assembly 6 is provided between the movable end of the electric push rod 11 and the two suction cup pull rods 12. The transmission assembly 6 includes a first connecting rod 61 and two second connecting rods 62, the first connecting rod 61 is located in the gap between the top plate 101 and the bottom plate 102, and the two second connecting rods 62 are at least partially located in the gap between the top plate 101 and the bottom plate 102, the middle position of the first connecting rod 61 is connected to the movable end of the electric push rod 11, and the two second connecting rods 62 are rotatably connected to the opposite ends of the first connecting rod 61, and one end of each second connecting rod 62 away from the first connecting rod 61 abuts against the surface of the bottom plate 102 facing the top plate 101, and the second connecting rod 62 is movable relative to the bottom plate 102, that is: the abutment point between one end of the second connecting rod 62 away from the first connecting rod 61 and the bottom plate 102 is equivalent to the lever fulcrum. One end of the suction cup pull rod 12 away from the suction cup 2 is rotatably connected to one end of the corresponding second connecting rod 62 away from the first connecting rod 61 .
[0063] Through such a setting, the movable end of the electric push rod 11 is connected to the two second connecting rods 62 through the first connecting rod 61, and the driving force can be evenly distributed to the two suction cup pull rods 12 when the electric push rod 11 is extended and retracted, ensuring that the two suction cups 2 are synchronously recessed or protruded, thereby improving the stability and reliability during the adsorption process. At the same time, the rotating connection structure of the transmission component 6 can adapt to small displacements in different directions, avoiding the jamming phenomenon caused by installation errors or uneven force during the driving process, thereby effectively improving the operational flexibility and adsorption performance of the circuit breaker opening and closing device under complex working conditions.
[0064] Exemplarily, the second connecting rod 62 is in the shape of an irregular hexagonal strip, with a small end rotatably connected to the first connecting rod 61 through a pin, and a large end rotatably connected to the suction cup pull rod 12 through a pin. The short side of the large end contacts the bottom plate 102, acting as a lever fulcrum.
[0065] like Figure 4 As shown, in some embodiments, the suction cup pull rod 12 includes a first sub-pull rod 121 and a second sub-pull rod 122, one end of the first sub-pull rod 121 is fixed to the suction cup 2, the other end of the first sub-pull rod 121 is rotatably connected to the second sub-pull rod 122, and one end of the second sub-pull rod 122 away from the first sub-pull rod 121 is rotatably connected to the second connecting rod 62. By dividing the suction cup pull rod 12 into two rotatably connected sub-pull rods, the suction cup pull rod 12 can more flexibly adapt to different angles and position changes during movement, thereby ensuring that the suction cup 2 moves more accurately and smoothly during adsorption and release.
[0066] Exemplarily, the first sub-tie rod 121 is rotatably connected to the second sub-tie rod 122 via a pin, and the second sub-tie rod 122 is rotatably connected to the second connecting rod 62 via a pin.
[0067] like Figure 4 As shown, in some embodiments, the base plate 102 is provided with a suction cup fixing frame 7, one end of the suction cup fixing frame 7 is fixedly connected to the base plate 102, the other end of the suction cup fixing frame 7 is fixedly connected to the suction cup 2, the interior of the suction cup fixing frame 7 has an accommodating space 71, and the suction cup pull rod 12 can be partially located in the accommodating space 71.
[0068] By providing the suction cup fixing frame 7, a stable supporting structure is provided for the suction cup 2, which can improve the stability of the suction cup 2 during operation and prevent the suction cup 2 from being misplaced or offset. In addition, the design of the accommodating space 71 allows the suction cup pull rod 12 to move freely therein, thereby effectively protecting the suction cup pull rod 12 and preventing it from being damaged by external collision or friction during operation.
[0069] Optionally, the suction cup fixing frame 7 is configured to be cylindrical, the suction cup 2 is configured to be circular and located at the front end of the suction cup fixing frame 7, and the material of the suction cup 2 can be configured to be rubber.
[0070] like Figure 3 and Figure 5 As shown, in some embodiments, the second driving assembly 3 includes a driving motor 31, a first gear 32 and a second gear 33. The driving motor 31 is installed in the gap between the top plate 101 and the bottom plate 102. The first gear 32 and the second gear 33 are rotatably connected to the surface of the bottom plate 102 away from the top plate 101. The first gear 32 is connected to the output end of the driving motor 31, and the second gear 33 is transmission-connected to the first gear 32. The toggle member 4 is installed on the second gear 33 and can move together with the second gear 33. Exemplarily, the first gear 32 is connected to the output end of the driving motor 31 through a keyway, and the second gear 33 is connected to the bottom plate 102 through a bearing.
[0071] Through such a motor plus gear transmission setting, the moving trajectory and the toggle force of the toggle member 4 can be accurately controlled, thereby improving the stability and reliability of the circuit breaker opening and closing operation. In addition, the gear transmission mechanism can amplify the output torque of the drive motor 31 to ensure sufficient driving force during the toggle operation, further improving the ability of the device to cope with different load requirements.
[0072] Optionally, the first gear 32 and the second gear 33 can be made of engineering plastics to reduce weight. Furthermore, the middle portion of the second gear 33 has a through hole for reducing weight to further reduce weight.
[0073] Optionally, the toggle member 4 in this embodiment is configured to be elliptical, so that the toggle member 4 can be allowed to slide to a certain extent when in contact with the circuit breaker handle, and has greater adaptability when operating circuit breakers of different specifications.
[0074] Optionally, the toggle member 4 is mounted on the second gear 33 by means of screws.
[0075] In some embodiments, the toggle member 4 is provided with a force sensor, which is used to sense the magnitude of the force applied to the toggle member 4. The force sensor can determine whether the toggle member 4 contacts the circuit breaker handle by sensing the magnitude of the force applied to the toggle member 4, thereby controlling the speed of the drive motor 31, that is, the speed is fast during the idle stroke, and the speed is slowed down when the toggle member 4 contacts the circuit breaker handle, so as to improve the opening and closing efficiency, reduce the impact when the toggle member 4 contacts the circuit breaker handle, and make the opening and closing process smoother.
[0076] like Figure 3 and Figure 5 As shown, in some embodiments, the operating mechanism 30 also includes a position sensing component, which includes a position sensor 8 and a plurality of position mark permanent magnets 9. The fixed end of the position sensor 8 is fixed to the top plate 101, and the sensing end of the position sensor 8 extends out of the bottom plate 102. The second gear 33 is fixed with a plurality of position mark permanent magnets 9. The plurality of position mark permanent magnets 9 are arranged at intervals, and the plurality of position mark permanent magnets 9 cooperate with the position sensor 8 to sense the rotation angle of the second gear 33.
[0077] Through such a setting, the position sensor 8 can sense and transmit the changes of the position marker permanent magnet 9, so that the robot can accurately sense the rotation angle of the second gear 33, thereby realizing real-time monitoring of the position and movement state of the second gear 33 to prevent the second gear 33 from not rotating in place or rotating excessively.
[0078] Exemplarily, the second gear 33 is semicircular in shape, and three position marking permanent magnets 9 are provided, which are respectively located at the extreme positions and the middle position at both ends of the second gear 33 .
[0079] When the robot provided in this embodiment opens and closes the circuit breaker, the operation steps are as follows:
[0080] S1. Install the circuit breaker opening and closing device 400 on the robot body 300, and move the circuit breaker opening and closing device 400 to a safe distance range of the power distribution cabinet to be operated by using the mobile vehicle 100;
[0081] S2. After the robot locates the position of the circuit breaker handle through the visual camera, it plans the path autonomously, places the circuit breaker opening and closing device 400 on the outer surface of the power distribution cabinet, and applies a certain pressure;
[0082] S3, the robot issues an adsorption command, the electric push rod 11 retracts, and the second connecting rod 62 is pulled by the first connecting rod 61, which in turn tightens the suction cup pull rod 12, so that the inside of the suction cup 2 is sunken to form a vacuum, and suction is generated to adsorb to the outer surface of the distribution cabinet;
[0083] S4, the robot issues an opening and closing command, the driving motor 31 is activated, the first gear 32 rotates under the action of the driving motor 31, drives the second gear 33 to move, and then drives the toggle member 4 to move together to toggle the circuit breaker handle;
[0084] S5.
