Description

AGV dolly is patrolled and examined to railway locomotive

Technical Field

The utility model belongs to the technical field of AGV vehicles, and particularly relates to an AGV trolley for railway locomotive inspection.

Background

AGV (AutomatedGuidedVehicles) also known as an unmanned carrier, an automatic navigator or a laser navigator. The self-guided AGV has the remarkable characteristics that the self-guided AGV is unmanned, the automatic guiding system is arranged on the AGV, the system can automatically run along a preset route without manual navigation,

according to the utility model, the patent of the AGV for railway locomotive inspection is searched and found that in the prior art, the authorized bulletin number is CN218431492U and the bulletin day is 2023-02-03, namely the patent solves the problem that the AGV is not blocked by a track compared with an AGV with fixed wheels and can stably cross the track, so that the running time of the AGV is shortened, and the inspection efficiency of parts at the bottom of a locomotive is greatly improved; the front universal wheel and the driving wheel at the same side are symmetrically suspended in a front-back balanced manner by two pairs of transverse swing arms; all wheel trains are enabled to land in real time at the moment, and suspended or slipping of driving wheels of an irregular road surface is avoided; all universal wheels are lifted in a group of two-to-one mode, the wheels and the universal wheels cannot sink into the grooves to cause blocking of AGV, and the surfaces of the grooves are like the track level. When the device uses laser navigation, however, when dust or other shielding objects are covered on the laser navigation in the running process, the normal running of the AGV trolley can be influenced, and the AGV trolley is separated from the original set route; when the AGV car deviates from the route, the wheels are easy to cling to the wall, so that the wheels cannot rotate, and the ideal effect is not achieved.
