Description

Technical Field

[0001] The utility model belongs to the technical field of electric power facilities, and specifically relates to an aerial plug-in actuator. Background Art

[0002] Switch cabinets need to be regularly inspected, maintained, replaced, overhauled, and tested, which requires the cooperation of maintenance teams, protection teams, and test teams. There are many projects and many cooperating operators, which results in a large number of tools and instruments required for each pre-test. At the same time, there are trolley-type circuit breakers in the switch cabinet. Trolley-type circuit breakers are large in size and heavy in weight. During replacement, overhaul, and testing, operators need to operate close to the switch cabinet. The degree of automation is low, and it is time-consuming and labor-intensive. In addition, on-site operations require repeated manual replacement of maintenance tools and test instruments, and frequent wiring changes, which not only makes the on-site test wiring numerous and messy, but also poses a risk of electric shock due to inadequate test safety measures.

[0003] At present, most maintenance robots are used to solve the above problems. The maintenance robot includes an operating part for opening the cabinet door and a carrying part for carrying the circuit breaker. The operating part includes a mechanical arm and a variety of maintenance tools that are compatible with the mechanical arm, namely, a key-turning actuator for opening the cabinet door, a switch actuator, a screw-turning actuator, and an aviation plug-in actuator for plugging and unplugging the aviation plug on the relay. The existing aviation plug-in actuator includes a plug-in quick-change fixture, a plug-in quick-change mounting plate supporting the plug-in quick-change fixture, a large suction cup connecting plate and a small suction cup connecting plate connected to the plug-in quick-change mounting plate, a large suction cup connecting plate is provided with a large suction cup, and a small suction cup connecting plate is provided with a small suction cup, and the suction cup is used to adsorb on the plug paddle to paddle the paddle; however, since the outer wall of the aviation plug is not a horizontal plane, this may cause the suction cup to fail to adsorb the aviation plug, or there is a risk of falling after successful adsorption, which makes the board aviation plug have an error rate, thereby affecting the subsequent work of carrying the circuit breaker.

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Please also read Figures 1 to 4, the utility model of the aviation plug-in actuator is described. The aviation plug-in actuator includes a toggle device 10, an exchange tool and a fixing device 30; the toggle device 10 includes a toggle rod 11 slidably connected therein and a driving unit 12 driving the toggle rod 11 to move along a predetermined trajectory, the bottom of the toggle rod 11 is provided with an abutment portion 111 extending to the outside of the toggle device 10, and the abutment portion 111 abuts on the paddle; the exchange fixture 20 is fixedly connected to the top of the toggle device 10 for rapid exchange with the robot's mechanical arm; the fixing device 30 is fixedly connected to the toggle device 10, and the bottom of the fixing device 30 is provided with a fixing portion extending to the outside of the toggle device.

[0031] The utility model provides an aviation plug plugging and unplugging actuator. Compared with the prior art, by setting a toggle rod 11 and a fixing part, when unplugging the aviation plug, the actuator is first installed on the mechanical arm through the exchange clamp 20, and then the aviation plug is fixed by the fixing part of the fixing device 30, and then the abutting part 111 of the toggle rod 11 abuts on the paddle, and then the driving unit 12 drives the toggle rod 11 to move along a predetermined trajectory, so as to push the paddle away, that is, to turn on the switch of the aviation plug, and finally the aviation plug can be unplugged through the action of the mechanical arm; this setting is more convenient for plugging and unplugging the aviation plug, and there will be no error rate when pulling away the paddle, and there will be no risk of the aviation plug falling.

[0032] Specifically, the aviation plug (full name: aviation plug) on ​​the circuit breaker generally includes a plug and a paddle connected thereto by rotation (realized by an axis) (the paddle is the lock of the aviation plug). The plug is docked with the socket on the circuit breaker. The paddle is arranged on the side of the plug away from the socket and can be moved along the left and right directions of the plug. The trajectory of its movement is the predetermined trajectory of the toggle rod 11. When the paddle is rotated to the left, the aviation plug can be opened, and when it is rotated to the right, the aviation plug can be locked. When the paddle is toggled, since the toggle rod 11 needs to abut against the paddle, when opening the aviation plug, the toggle rod 11 abuts against the inner side of the paddle, that is, the side facing the plug, and the paddle is pushed outward under the drive of the drive unit 12. When installing the aviation plug, the toggle rod 11 abuts against the outer side of the paddle, that is, the side away from the plug, and the paddle is pushed inward under the drive of the drive unit 12, so that the paddle is locked.

[0033] Specifically, after the circuit breaker is overhauled and pushed into the switch cabinet, the robotic arm quickly replaces the aviation plug-in actuator through the exchange fixture. Then, the fixing part of the fixing device 30 fixes the corresponding aviation plug, and after moving it to the predetermined position of the switch cabinet, the toggle rod 11 abuts against the paddle and locks the aviation plug under the drive of the drive unit 12.

[0034] Specifically, the robotic arm is fixed to the operating part of the maintenance robot. The robotic arm can be extended and moved in the front, back, left and right directions. Therefore, after the aviation plug is opened, the robotic arm drives the fixing device 30 to move away from the aviation plug, so that the aviation plug can be unplugged.

[0035] In some embodiments, an improved implementation of the above-mentioned aviation plug-in actuator can be adopted as follows Figure 2 , Figure 4 See the structure shown. Figure 2 , Figure 4 The toggle device 10 also includes a box body 13, a mounting plate 14 is fixedly connected to the box body 13, an arc-shaped slide groove 15 is opened on one side of the mounting plate 14, and the toggle rod 11 is slidably connected to the arc-shaped slide groove 15; the driving unit 12 includes a motor 121 and a transmission plate 122; the motor 121 is fixedly connected to the mounting plate 14, and the arc-shaped slide groove 15 is arranged on the front and rear sides of the mounting plate 14, and the output shaft of the motor 121 passes through the mounting plate 14; the transmission plate 122 is arranged between the output shaft of the motor 121 and the toggle rod 11, and a strip groove 123 is opened on the transmission plate 122, and the toggle rod 11 is slidably connected to the strip groove 123. The rotation of the transmission plate 122 is driven by the rotation of the motor 121. Since the transmission plate 122 is provided with a strip groove 123, and the toggle rod 11 is slidably connected to the strip groove 123 and the arc-shaped slide groove 15 respectively, the rotation of the transmission plate 122 can drive the toggle rod 11 to slide along the arc-shaped slide groove 15, thereby driving the opening and locking of the paddle; the moving path of the toggle rod 11 in the arc-shaped slide groove 15 is the above-mentioned predetermined trajectory, and the moving path is basically consistent with the rotation path of the paddle, so the toggle rod 11 can drive the paddle to rotate; this setting can not only limit the moving path of the toggle rod 11, but also better drive the rotation of the paddle, thereby avoiding the occurrence of error rate.

[0036] In some embodiments, an improved implementation of the above-mentioned aviation plug-in actuator can be adopted as follows Figure 2 , Figure 3 See the structure shown. Figure 2 , Figure 3The driving unit 12 further comprises a sliding shaft 124, which is slidably connected to the arc-shaped slide groove 15 and the strip groove 123 in sequence, and the portion of the sliding shaft 124 that passes through the strip groove 123 is fixedly connected to the toggle rod 11. The sliding shaft 124 that is detachably connected to the toggle rod 11 is provided to realize the sliding of the toggle rod 11 in the arc-shaped slide groove 15 and the strip groove 123, respectively. The sliding shaft 124 has two sliding blocks, which slide in cooperation with the arc-shaped slide groove 15 and the strip groove 123, respectively. Then, the sliding shaft 124 passes through the strip groove 123 and is connected to the toggle rod 11 by bolts, so as to facilitate the disassembly and replacement of the toggle rod 11 or the sliding shaft 124.

[0037] In some embodiments, an improved implementation of the above-mentioned aviation plug-in actuator can be adopted as follows Figure 2 See the structure shown. Figure 2 The driving unit 12 also includes a slide plate 125 and a slider 126; the slide plate 125 is fixedly connected to the bottom of the arc-shaped slide groove 15, the slide plate 125 is parallel to the length direction of the mounting plate 14, and the top and bottom of the slide plate 125 are provided with a first slide groove 127; the slider 126 is slidably matched with the two first slide grooves 127, and a second slide groove 128 is provided on the side of the slide plate 126 away from the slide plate 125, the second slide groove 128 is perpendicular to the first slide groove 127, and the toggle rod is slidably matched with the second slide groove 128. By arranging a slide plate 125 and a slider 126 below the arc-shaped slide groove 15, the slider 126 can slide along the slide plate 125, and a second slide groove 128 is arranged on the slider 126, and the toggle rod 11 slides in cooperation with the second slide groove 128, so that when the top of the toggle rod 11 slides along the arc-shaped slide groove 15, the middle part thereof can move along the length direction and height direction of the slide plate 125. This setting can limit the middle part of the toggle rod 11 to prevent the toggle rod 11 from shaking, thereby affecting the insertion and removal of the aviation plug.

[0038] In some embodiments, an improved implementation of the above-mentioned aviation plug-in actuator can be adopted as follows Figure 2 See the structure shown. Figure 2 The toggle device 10 further includes a plurality of travel switches 129, each of which is fixedly connected to the left and right sides of the arc-shaped slide 15. By setting the switch, the moving position of the toggle rod 11 can be monitored; the travel switches 129 are respectively set on the left and right sides of the arc-shaped slide 15, and two travel switches 129 can be set on each side. When the toggle switch moves to the end of the arc-shaped slide 15, the travel switch 129 is activated and sends a command to the robot arm through the control system, and then the robot arm drives the actuator to leave.

[0039] Specifically, the travel switches 129 on different sides can be numbered respectively, such as the travel switch 129 on the left side of the arc-shaped slide groove 15 is numbered 1, and the travel switch 129 on the right side is numbered 2. It is set in advance in the control system. When the No. 1 travel switch 129 sends an instruction, the aviation plug is opened. At this time, an instruction is sent to the robot arm to drive the fixing device 30 to move and unplug the aviation plug. When the No. 2 travel switch 129 sends an instruction, the aviation plug is closed. At this time, an instruction is sent to the fixing device 30 to release the aviation plug, and then an instruction is sent to the robot arm to drive the aviation plug plug-in actuator to leave.

[0040] In some embodiments, an improved implementation of the above-mentioned aviation plug-in actuator can be adopted as follows Figure 4 See the structure shown. Figure 4 The fixing device 30 includes a transmission box 31 and two clamps 32; the transmission box 31 is fixed to the mounting plate 14 and is located on the same side as the motor 121; the two clamps 32 are slidably connected to the bottom of the transmission box 31, and the two clamps 32 move in relative or opposite directions respectively, a clamping space is formed between the two clamps 32, and the two clamps 32 and the clamping space form a fixing portion. The fixing of the aviation plug is achieved by setting the clamps 32, and the movement of the two clamps 32 can adapt to aviation plugs of different sizes, and the transmission box 31 is a prior art (refer to the electric clamps 32), which can drive the two clamps 32 to move, so that the aviation plug can be better fixed, avoiding the phenomenon of unsuccessful adsorption of the suction cup.

[0041] Specifically, a motor, a slide rail, a screw and two sliders can be arranged inside the transmission box 31. The thread on the screw is divided into two parts, a left part and a right part. The thread of the two parts has opposite rotation directions. The two sliders are respectively screwed to the thread parts with different rotation directions, and the sliders slide on the slide rails. The two clamps 32 are respectively connected to the two sliders. When working, the motor drives the screw to rotate, and the rotation of the screw drives the two sliders to move relative to or towards each other, thereby adjusting the distance between the two clamps 32.

[0042] The above are only preferred embodiments of the utility model and are not intended to limit the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
