Problems solved by technology
[0005] Purpose of the invention: The present invention provides a switch cabinet grounding knife switch operating mechanism, which is used to solve the problem that the existing ground knife automatic operating mechanism is exposed to the endoscope wire harness, which is easy to wear and break, and the overall structure has poor rigidity. Due to the large friction coefficient of the ordinary spline shaft, the resistance is relatively large, which eventually leads to technical problems such as low success rate of operation

[0059] S1 Coarse positioning: After the robot is in place, the posture adjustment of the rack 100 is realized through the cooperation of the rack assembly 200 and the depth camera 206 until the operation assembly 300 rotates to a position perpendicular to the switch cabinet surface, and the pressure plate assembly 500 is located on the ground. above the knife cover;
[0060] S2 Open the floor knife cover: the output shaft assembly drives the pressure plate assembly 500 to extend until the floor knife pressure plate 501 is against the cabinet surface, and then the frame assembly 200 drives the pressure plate assembly 500 to press down the floor knife cover;
[0061] S3 fine positioning: After the ground knife cover is opened, the image is collected by the depth camera 206 and the endoscopic probe, and the concentricity and relative angle adjustment between the floating operation cylinder 322 and the operation head are realized in cooperation with the robot and the frame assembly...

The invention discloses an operating mechanism for a switch cabinet grounding knife switch, which comprises an integral frame, a frame assembly, an operating assembly, and a pressing plate assembly. The operating assembly includes a driving assembly, a high-torque bushing assembly, an output shaft assembly, and a telescopic tube assembly 1. Floating operation cylinder; the output shaft assembly includes a rolling screw, a screw nut, a ball spline shaft, and a ball spline sleeve that are sequentially socketed from the inside to the outside, wherein the screw nut and the ball spline shaft are driven by a key Connection, the ball spline pair is formed between the ball spline shaft and the ball spline sleeve, the endoscopic probe is arranged in the floating operation cylinder, and the rolling screw rod is a hollow structure, which is used to realize the wiring harness of the endoscopic probe. The invention adopts the ball spline pair to effectively reduce the telescopic resistance, the guide rail slider pair can increase the rigidity of the whole assembly, the telescopic tube can protect the endoscope wire harness, and at the same time completely hide the wire harness, thereby greatly improving the operation success of the grounding knife switch Rate.
Description
technical field [0001] The invention relates to a switch cabinet grounding knife switch operating mechanism, which belongs to the technical field of indoor operating robots. Background technique [0002] The robot with integrated operation and inspection functions can optimize the traditional working mode of multi-point deployment and maintenance of a group of operation tasks in the substation. Coordinated optimization and operational response time have brought huge benefits. Through remote deployment and control, high-risk live work can be completed efficiently and accurately. [0003] Although some of the existing ground knife operating mechanisms can realize automatic operation, there are still exposed wire harnesses of the endoscope, which are easy to wear and break, and the overall structure is poor in rigidity. Then the resistance is relatively large, which eventually leads to technical problems such as low success rate of operation. [0004] Based on this, the prese...
