Description

Coke oven rail vehicle collision energy-absorbing device

Technical Field

The utility model belongs to the technical field of coke oven machinery, a coke oven rail vehicle collision energy-absorbing device is related to.

Background

The coke oven rail vehicle comprises a coal charging car, a coke pushing car, a coke quenching car, a coke tank car and a coke guide car, and is important coke oven production equipment. In the coking production process, because accidental human errors or mechanical faults are inevitable, vehicle collision accidents happen sometimes, and huge production loss and equipment loss, even casualties, are caused. Improving the crashworthiness of a vehicle is the most effective way to reduce the impact of a crash. At present, when the crashworthiness of the coke oven rail vehicle is designed, a common method is that a plastic safety catch is arranged on a bracket in front of a traveling wheel at two ends of the vehicle, and the impact force to the vehicle during the collision is reduced by the plastic deformation of the safety catch; the coke oven rail vehicle belongs to large coke oven machinery, has larger weight (more than 100 tons), has larger kinetic energy when the vehicle collides, has less plastic deformation due to a safety catch made of plastic material, has not ideal collision protection on the vehicle in actual collision, and has larger damage when the vehicle collides; in addition, the vehicle is positioned around the coke oven, the environmental temperature is higher, the plastic safety gear is easy to age, crack, fall off and lose effect, and the service life is shorter.

SUMMERY OF THE UTILITY MODEL

In order to overcome prior art's above-mentioned shortcoming, the utility model provides a coke oven rail vehicle collision energy-absorbing device can conveniently install at the rail vehicle tip, at vehicle collision in-process, plays the effect of dissipation collision kinetic energy, to the damage of vehicle when reducing the collision, and the device simple structure, change convenience, long service life have practiced thrift manpower and materials.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a coke oven rail vehicle collision energy-absorbing device, including installing the fixed pipe on the base, fixed pipe rear end has inserted the slip pipe, be swing joint between two pipes, the welding of slip pipe left end head circumference has the dog, prevent that the slip pipe from deviating from, when taking place elastic deformation, the movable pipe is extruded and slides along fixed pipe wall, the slip pipe other end is fixed with the collision baffle, the welding has the dog on fixed pipe and the slip pipe junction circumference inner wall, install compression spring in fixed pipe and movable pipe, when the vehicle bumps, the collision baffle transmits the impact to compression spring, take place elastic deformation through compression spring and absorb, consume collision kinetic energy.

One end of the compression spring is fixed on the base, and the other end of the compression spring is fixed on the collision baffle.

The outer diameter of the sliding guide pipe is smaller than the inner diameter of the circumference of the fixed guide pipe of the welded stop block.

The fixed guide pipe is provided with an oil filling hole for regularly filling oil to lubricate the circumference of the inner wall of the connecting port of the fixed guide pipe and the sliding guide pipe, so that the sliding guide pipe is ensured to be flexible, and the connecting part of the guide pipe is prevented from being rusted.

The base is fixed on the original vehicle through bolts.

The utility model has the advantages that: can conveniently install at rail vehicle tip, at vehicle collision in-process, play the effect of dissipation collision kinetic energy, to the damage of vehicle when reducing the collision, and the device simple structure, change convenience, long service life have practiced thrift manpower and materials.
