[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Please also refer to Figures 1 to 7The circuit breaker plug extractor provided by the present invention is now described. The circuit breaker plug extractor comprises: a quick-change tool tray 1, a lever assembly, a clamping and plugging assembly, and a protective cover 3. The quick-change tool tray 1 is used to dock with the robotic arm of an operation and maintenance robot; the lever assembly comprises a lever driving mechanism and a lever 8; the lever 8 is driven by the lever driving mechanism to unlock the plug extractor 5 between the circuit breaker plug 7 and the circuit breaker socket 6; the clamping and plugging assembly comprises an electric clamp 4, which has a pair of clamping jaws 41 for clamping the circuit breaker plug 7; the electric clamp 4 clamps the circuit breaker plug 7 and inserts and removes it with the help of the robotic arm; the protective cover 3 is fixed to the quick-change tool tray 1; the electric clamp 4 and the lever driving mechanism are both installed in the protective cover 3.

[0026] Compared with the prior art, the circuit breaker plug 7 plug-in / extractor provided by the present invention has the following advantages: by integrating the lever 8 capable of dislodging the plug-in auxiliary extractor 5 with the electric clamping claw 4 capable of clamping the circuit breaker plug 7, the lever 8 can be used to dislodge the plug-in auxiliary extractor 5 through the cooperation of the mechanical arm of the operation and maintenance robot, and then the circuit breaker plug 7 can be pulled out from the circuit breaker socket 6. This operation simplifies the operation procedure, shortens the operation and maintenance time, eliminates the need for manual unlocking, and reduces safety hazards.

[0027] The circuit breaker plug 7 plug-in and pull-out device provided by the utility model is used in conjunction with an operation and maintenance robot. The mechanical arm of the operation and maintenance robot is used to automatically dock with the quick-change tool tray 1, and the lever assembly is used to unlock the plug puller 5 between the circuit breaker plug 7 and the circuit breaker socket 6. Then, the clamping plug-in assembly clamps the circuit breaker plug 7 and the mechanical arm is used to pull out the circuit breaker plug 7.

[0028] Optionally, the electric clamp 4 is an RM electric linear cylinder RM-GB-11-40-2 expanded servo flexible clamp. The clamping and plugging assembly can also be a pneumatic clamp.

[0029] In some embodiments, see Figure 7 As shown, the lever drive mechanism includes a micromotor, a swing arm 12 connected to the main shaft of the micromotor, and a limiting slide 10. The swing arm 12 is provided with a limiting slide 121, and the limiting slide 10 is provided with an arc groove 101. The rear end of the lever 8 is limited by the limiting slide 121 and the arc groove 101 through the follower block 13, so that after the micromotor is started, the plug extraction device 5 is rotated open along the trajectory limited by the limiting slide 121 and the arc groove 101. The limiting slide 10 is installed on the protective cover 3.

[0030] The process is as follows: the micromotor first rotates in the reverse direction, and the lever 8 rotates away from the plug extractor 5 to open the lever outward so that the first hook at the front end of the lever will not be interfered with when approaching the plug extractor 5. When the front end of the lever overlaps with the plug extractor 5 laterally, the micromotor rotates forward, causing the lever to approach and push the plug extractor 5 laterally, and gradually move backward, so that the plug extractor rotates around its axis under the push of the lever, and the hook of the plug extractor 5 gradually leaves the locking post on the circuit breaker socket. When the plug extractor 5 leaves the locking post on the circuit breaker socket, the plug extractor 5 can be opened by pressing backward.

[0031] Optionally, the micro motor is a high-quality 50ZY large torque motor.

[0032] In some embodiments, see Figure 7 As shown, a chute bottom plate 11 is further provided in the protective cover 3, the limiting slide plate 10 is mounted on the chute bottom plate 11, and the micro motor is mounted on the chute bottom plate 11. The electric gripper 4 is also mounted on the chute bottom plate 11.

[0033] Among them, the protective cover 3 is divided into two parts, including an upper cover body and a lower cover body. The slide bottom plate is installed between the upper cover body and the lower cover body and divides the protective cover into two sections. The electric gripper and micro motor are installed in the same section, and the limit slide, swing arm and lever are installed in the other section.

[0034] The various components in this application are assembled together by bolts, and assembly and disassembly are simple and convenient; among them, the main shaft of the micro motor passes through the through hole on the bottom plate of the slide slot, and a bearing matching the main shaft is provided in the through hole to ensure the flexibility of the main shaft rotation, and the swing arm is also installed on the shaft end of the main shaft by screws; the swing arm can also be connected to the main shaft by a key to ensure the synchronous rotation of the swing arm and the main shaft.

[0035] In some embodiments, see Figure 7 As shown, the follower block 13 includes a screw 132 and a follower wheel 131 that passes through the screw 132. The screw 132 is fixed to the shift lever 8, and the follower wheel 131 is located within the limiting groove 121 and the arcuate groove 101. The follower wheel 131 is restrained within the limiting groove 121 and the arcuate groove 101, and the movement trajectory of the shift lever 8 is limited by the trajectory of the intersection of the limiting groove 121 and the arcuate groove 101.

[0036] A follower wheel 131 is distributed in each of the limiting sliding groove 121 and the arc groove 101 .

[0037] In some embodiments, see Figure 7As shown, a transverse linear guide 9 is provided on the chute base plate 11. The lever 8 includes a longitudinal linear guide and a lever head 81 mounted at the front end of the longitudinal slide 82 of the longitudinal linear guide. The longitudinal slider 83 of the longitudinal linear guide is mounted on the transverse slider of the transverse linear guide 9.

The micromotor drives the longitudinal slide 82 longitudinally and transversely via the swing arm 12, the limiting slide 10, and the follower block 13, so that the lever head 81 rotates the plug extractor 5 open. The transverse linear guide 9 and the longitudinal linear guide convert the rotational motion of the swing arm 12 into longitudinal and transverse linear motion trajectories, thereby dislodging the plug extractor 5.

[0038] The present application directly selects the appropriate linear guide rail for simple and convenient assembly without the need for processing. Optionally, the horizontal linear guide rail 9 is MGW12H and the vertical linear guide rail is MGN12C.

[0039] In some embodiments, see Figures 5 to 7 As shown, the front end of the lever head 81 is provided with a first hook 811 for moving the plug extractor 5. The plug extractor 5 is hooked by the first hook 811 and is opened.

[0040] In some embodiments, see Figures 5 to 7 As shown, one of the clamping jaws 41 is provided with a second hook 411, and the inner side surface of the other clamping jaw 41 is provided with an anti-slip pad 412. The second hook 411 of the clamping jaw 41 hooks the circuit breaker plug 7, and the other clamping jaw 41 clamps the side surface of the circuit breaker plug 7, positioning the circuit breaker plug 7 from different directions to facilitate removal of the circuit breaker plug 7.

[0041] In some embodiments, see Figures 1 to 7 As shown, an adapter base 2 is further provided between the protective cover 3 and the quick-change tool tray 1. The adapter base 2 includes an adapter plate 23 fixed to the quick-change tool tray 1, a fixing base 22 fixed to the adapter plate 23, and a fixing plate 21 fixed to the fixing base 22. The protective cover 3 is fixed to the fixing plate 21 by bolts. The fixing plate 21 includes a mounting plate extending between the upper and lower covers of the protective cover 3. The mounting plate is fixed to the chute bottom plate 11 by bolts.
