The invention relates to the field of rail-mounted container cranes and discloses a positioning detection device and method for a rotary trolley. The positioning detection device comprises a power device, an upper trolley platform and a lower trolley platform, wherein the upper trolley platform and the lower trolley platform oppositely rotate; the upper trolley platform is provided with a first sensor group; the first sensor group comprises N sensors distributed in a radial direction; a circular track arranged on the lower trolley platform comprises N sub-tracks distributed in a radial direction along the rotating center of the lower trolley platform; each sub-track is provided with at least two identification codes; N sub-tracks correspond to N sensors one by one and are matched with the N sensors in the radial extension direction of the rotating center of the upper trolley platform; at least two first positioning points are uniformly arranged in the circumferential direction of the rotating center of the lower trolley platform; the identification codes on corresponding N sub-tracks are combined into stop codes on the circular track to which each positioning point is opposite; decelerating codes are formed through combination within preset ranges at two sides of the circumferential directions of each first positioning points, wherein N is greater than or equal to 3.
Description
technical field [0001] The invention relates to the field of rail-mounted container cranes, in particular to a positioning detection device and a positioning detection method for a rotary trolley. Background technique [0002] At present, the track 4 type container crane (RMG) traveling trolley in the railway yard is divided into upper and lower parts. The upper trolley 1 of the crane needs to be rotated and positioned on the circular track 4 to ensure that the container can be placed horizontally, vertically, and turned around when lifting and transporting the container. The positioning angles are 0°, 90° and 180°. At the same time, deceleration zones 3 are provided on both circumferential sides of the three positioning angles. [0003] Specifically, please refer to figure 1 , the upper trolley 1 is equipped with three radially distributed sensors 5; correspondingly, the lower trolley 2 is provided with three radially distributed annular tracks 4, and the three tracks 4 ...
