Description

Positioning vehicle driving small tooth anti-falling device Technical Field The utility model relates to a positioning vehicle driving small tooth anti-falling device, and belongs to the technical field of mechanical driving degradation prevention. Background The positioning vehicle is used for pushing the train carriage and helping the train carriage to be accurately positioned on the tippler. The positioning vehicle is generally composed of a plurality of longitudinal drives, the longitudinal drives are sequentially composed of a motor, a speed reducer and driving small teeth from top to bottom, and the driving small teeth always have a falling trend due to the action of gravity in the operation process. Because the pinion card board bolt is not hard up or the unbalanced pinion atress can aggravate the trend of falling, finally leads to the drive pinion to drop, and the pinion drops after dropping in the locating car track foundation ditch, and the interval of locating car track and locating car drive rack track fastener is less than the diameter of drive pinion, and the installation height of locating car horizontal wheel is less than the height of drive pinion, therefore the drive pinion drops the back that can promote the drive pinion that drops of locating car and causes the destruction to other steel construction in the foundation ditch, and the loss is great. Based on the above, it is necessary to design a positioning vehicle driving small tooth anti-falling device to meet the requirement of field use. In addition, in the conventional technology, in order to ensure that the components of the equipment are kept horizontal, structures such as a level meter and the like are arranged, additional structures are added, and meanwhile, the reset performance of the structures is also lacked, and complex reset structures are required to be arranged.
