[0005] The detection process of the switchgear needs to complete the detection on the four sides of the switchgear respectively. There are two options for the detection process: first, the switchgear does not move, and the detection equipment rotates around the switchgear to complete the detection. This method requires additional movement of the detection equipment. track, and requires a large working space in the carriage, so it is rarely used at present; second, the detection equipment does not move, and the switch cabinet rotates to complete the detection. This method requires less work space in the carriage, but it needs to consider the inaccurate positioning of the switch cabinet Detection error caused by

Embodiment Construction
[0024]DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS It should be noted herein to help understand the present invention, but is not intended to be limited to the present invention.
[0025]AppendFigure 1 ~ 4As shown, the rotary positioning device is detected based on servo-driven in-vehicle switchgear, including gear rotary support 300, the servo motor 8122 and the reducer 305, the detection platform 302, and the positioning sensor 303 of the drive gear rotation support 300.
[0026]The detection platform 302 is mounted on the gear rotary support 300, from the servo motor 8122 and the reducer drive gear rotation support 300, drive the detection platform 302 to rotate;
[0027]The positioning sensor 303 detects four orientations of the platform, and the positioning of the detection platform 302 is realized by the relative coordinate relationship between the positioning sensor 303;
[0028]The detection platform 302 includes a power drum assembly 812; the power roller assembly 812 includes two...

The invention relates to the technical field of electrical switch cabinet detection, and discloses a vehicle-mounted switch cabinet detection rotation positioning device based on servo drive. The device comprises a gear slewing bearing, a servo motor, a speed reducer, a detection platform and a positioning sensor, the detection platform is installed on the gear slewing bearing, and the servo motor and the speed reducer drive the gear slewing bearing to drive the detection platform to rotate. The positioning sensors respectively detect four directions of the platform; the power roller assembly comprises two servo motors and a row of rollers with the two ends movably arranged on the frame. Gears are arranged at the two ends of the rollers, the gears between the rollers are meshed with each other, and the gears of the rollers are meshed with a gear of a servo motor and are driven by the servo motor; and the gears between the adjacent rollers are rigidly connected and movably connected with the rollers respectively, so that all the rollers have the same rotating direction. By using the rotary positioning device, non-stop detection of the switch cabinet is realized, and the device has the advantages of good stability, strong adaptability and the like.
Description
Technical field[0001]The present invention relates to the technical field of electro-switching cabinet detection, and in particular, to the detection of rotation positioning devices based on servo-driven in-vehicle switchgear.Background technique[0002]The high and low pressure switchgear in the power system is an indispensable device, and the high and low voltage switchgear has a very important impact on the normal operation of the entire power system and power distribution. The main role of the high and low pressure switchgear is to perform the opening and closing, controlling and protection of electric equipment in power generation, transmission, distribution and power transmission, and is widely used in power plants, substations, petrochemicals, metallurgical steel. Light industry textile, plant enterprises and residential communities, high-rise buildings, etc.[0003]However, the switchgear is inevitably affected by the equipment, the environment, and human factors in the producti...
