The utlity model has following beneficial effect:
1, the utility model can improve freight-transport capacity under the railway existence conditions, alleviate the situation of prerssure on transport, satisfy fully that the user is big to limestone hopper car load carrying ability, intensity is high, the high requirement of the efficient of unloading, and have characteristics such as operation light safety, labor condition are good, be the renewal product of domestic existing limestone hopper car.
2,, adopt K13BK type limestone hopper car, 3000 tons of every train actual shipment goods as 50 of every train marshalling list.And adopt 70 tonnes of limestone hopper cars, and then can load and transport 3500 tons, under other traffic condition unmodified situations, 500 tons of the things of can freighting improve transport capacity 17% more, have tangible economic benefit and social benefit.
3, the utility model has adopted the high-strength weather-resistant structural steel, can prolong vehicle operation life-span and period of inspection and repair, reduces the operation cost of vehicle.
4, dress can effectively reduce application force between wheel track with changeing K6 type bogie truck, reduces each several part and wears away, and can realize the freedom from repairs management, significantly reduces maintenance workload.Can cancel in daily use and supplementally taking, implementation routine inspection, fault are entrusted and are repaiied.Repair on the basis in preventative plan, can carry out state repaiies, changes part and repair to concentrate with the specialization of main parts size and repair, set up the maintenance pattern that combines by traveling km and " equivalent km ", can significantly reduce the recondition expense of vehicle, improve vehicle operation efficient.
5, the utility model adopts the advanced computer aided design and the means of analysis to carry out the design of car load, and deceleration and stopping performance, driving system self-locking property, switching resistance etc. are checked calculating, can improve the reliability of train operation.
6, the anti-control techniques of active adoption labor safety when design strengthens personal job safety protective capacities.In addition, generally select the car body materials that can obtain comprehensive application for use, alleviate or eliminate harm, to satisfy the needs of cleaner production human health and environment.
