Description
Technical Field
The utility model relates to a positioner, concretely relates to attached positioner of railway flatcar chassis.
Background
The railway flatcar is one of the main railway vehicles in logistics, and the auxiliary parts on the underframe of the railway flatcar are various, and are mainly used for fixing the braking device (namely a braking pipe system comprising various valves, air cylinders, braking pipes and the like), and the position of each auxiliary part on the underframe is correct or not, so that the railway flatcar plays a crucial role in the subsequent assembly process of the braking device. The underframe accessories mainly comprise a 120-type control valve (namely a 120-type valve) hanging support, a brake cylinder hanging support, an air cylinder hanging support, a derailment valve hanging support, a pressure limiting valve hanging support, a manual brake pull rod fulcrum seat hanging support and the like, and are distributed on a center sill lower wing surface, a center sill web plate, a cross beam web plate and a side beam web plate of the underframe of the railway flat car and are distributed relatively discretely.
At present, a marking method is mainly adopted when the accessory of the underframe of the railway flat car is positioned, and the specific process is as follows: the method comprises the following four problems in production that the mounting positions of each lifting support during design are marked on the underframe of the railway flatcar, and then each lifting support is welded at the corresponding position:
first, the position accuracy is poor. During scribing, some references cannot be directly scribed on the middle beam lower airfoil surface, the middle beam web plate, the cross beam web plate and the side beam web plate, a square and the like are needed for conversion, direct positioning cannot be achieved, and low precision and low efficiency are caused by layer-to-layer conversion.
Second, the efficiency is low. 120 valve hanging holds in the palm, brake cylinder hanging holds in the palm, reservoir hanging holds in the palm, derail valve hanging holds in the palm, pressure limiting valve hanging holds in the palm, hand brake pull rod fulcrum seat hanging holds in the palm etc. in the attached spare need mark one by one and fix a position, can just right, if the location line is marked wrong, still need the back-work of back process, influence production efficiency.
Third, the location association is not strong. Because the underframe accessories are used for fixing the braking devices, sometimes one or more lifting brackets of the same type of one braking device are required to be fixed, and the core disc for positioning and the derailing valve lifting bracket have a strict relative position relationship, the position relevance among the lifting brackets can not be effectively ensured by single marking positioning in the existing marking method.
Fourthly, the hanging support position needs to be adjusted repeatedly during assembly, which wastes time and labor. As the types of accessories of the chassis of the flat car are more, the weight of a part of derailing valves in the chassis lifting bracket reaches 23.4kg, the positions of the derailing valves need to be adjusted back and forth during assembly, and the labor is consumed very much.
