Problems solved by technology

However, the problem of uncoordinated overall rigidity of the stone sweeper has not been effectively improved, and the impact of the rail on the stone sweeper may still cause cracks in the weak parts of the stone sweeper
In the case of poor road conditions, fatigue cracks are still prone to occur, and the problem of cracks cannot be fundamentally solved
Cracks in the stone sweeper not only pose a certain hidden danger to the safe operation of the locomotive, but also constantly replace the cracked stone sweeper will cause huge waste of manpower and resources

Abstract

The invention provides a railway locomotive stone sweeper. A sweeping head is fixed to the lower end of a support through a bolt, the upper end of the support is fixed to a bogie frame through a closed-loop plate suspension and a bolt, and the closed-loop plate suspension is composed of two upper opening convex installing plates mutually insert-overlapped and fixed through a bolt. The railway locomotive stone sweeper is coordinative in overall rigidity, has certain flexibility, can absorb vibration and impact and accordingly decrease cracks remarkably. The requirement for a manufacturing process is relatively simple, and quality is easy to ensure. The railway locomotive stone sweeper is convenient to install and facilitates field replacement.

Description

technical field [0001] The invention relates to a stone sweeper for railway locomotives, belonging to the technical field of railway locomotive manufacturing. Background technique [0002] A kind of locomotive stone sweeper in the prior art is a hanging structure. For example, the locomotive stone sweeper disclosed in Chinese Patent No. ZL200720016184.6 is composed of brackets, cross bars, sweeping heads, connecting plates, safety chains and other components. See attached figure 1 . The bracket 1 is a profiled plate structure, the sweep head 5 is fixed under the front end of the connecting plate 6, the cross bar 2 rigidly connects the left and right brackets, the chain 3 suspends the cross bar 2 on the bogie frame 4, and the sweep head 5 is a vulcanized clamp Cloth rubber sheet construction. See attached figure 2 , although this structure can bear a large longitudinal load due to the large longitudinal stiffness of the bracket, while the longitudinal stiffness of the sw...
