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

specific Embodiment approach

[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...

Abstract

The invention discloses a switch cabinet grounding knife switch operation mechanism, and the mechanism comprises an integral rack, a rack assembly, an operation assembly and a pressing plate assembly; the operation assembly comprises a driving assembly, a large-torque sleeve assembly, an output shaft assembly, a telescopic pipe assembly and a floating operation cylinder; the output shaft assembly comprises a rolling lead screw, a lead screw nut, a ball spline shaft and a ball spline sleeve which are sequentially connected in a sleeved mode from inside to outside, wherein the lead screw nut is in key transmission connection with the ball spline shaft, a ball spline pair is formed between the ball spline shaft and the ball spline sleeve, an endoscopic probe is arranged in the floating operation cylinder, and the rolling lead screw is of a hollow structure, and is used for threading the wire harness of the endoscopic probe. The telescopic resistance is effectively reduced through the ball spline pair, the rigidity of the whole assembly can be improved through the guide rail sliding block pair, the telescopic pipe can protect an endoscope wire harness, meanwhile, the wire harness can be completely hidden, and therefore, the operation success rate of the grounding knife switch is greatly increased.

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...
