Description

Technical Field

[0001] The utility model relates to a heavy vehicle detection and positioning device, in particular to a heavy vehicle detection and positioning device based on photoelectric sensing. Background Art

[0002] When disassembling the hook, it is necessary to quickly and accurately locate the hook position to achieve rapid positioning, improve the efficiency of disassembly, reduce the number of interruptions of automatic operation of the disassembly mechanism, and reduce the downtime. The existing positioning devices that use positioning vehicles for detection mostly use infrared reflective photoelectric sensors. This positioning method requires PLC scanning and calculation, and has a delay, as well as the uncertainty of the size of this delay. The positioning vehicle must move at a very slow speed to perform positioning, but this will greatly affect the operating efficiency of the positioning vehicle.

[0003] In addition, due to the limitations of the infrared reflective photoelectric sensor itself, when there is bad weather such as rain, snow, fog, and strong wind, the positioning is very inaccurate, which seriously restricts the efficiency of the disassembly operation. Utility Model Content

Specifically, the photoelectric sensing device has a light-emitting component and a light-receiving component, which are structurally separated from each other and do not interfere with each other during operation. Two photoelectric sensing devices are used for opposite shooting. The light beam emitted by the light-emitting component of one photoelectric sensing device is directed to the light-receiving component of the other photoelectric sensing device.
