When the train passes, the vibration will cause the surrounding gravel to roll down and shrink the cavity, which will cause damage to the base of dowty retarder, which will need to be stopped for maintenance and cause loss of human and material resources. Therefore, it provides a kind of buffer protective cover of dowty retarder that can eliminate the stone slag falling from the train vibration outside the working range of dowty retarder, avoid the damage of the speed bump and eliminate the hidden danger of the accident.
The utility model aims to overcome the above shortcomings, and provides dowty retarder buffer protection sleeve which can exclude the stone slag falling from the train vibration from the working range of the retarder, avoid the damage of dowty retarder, and eliminate the hidden danger of accidents.
The utility model is realized by connecting a protective sleeve at the lower end of dowty retarder through the following technical scheme. The protective sleeve is a hollow cylinder. More than one buffer column is arranged on the inner bottom of the protective sleeve. The inner and / or outer walls of the lower section of the protective sleeve are provided with stiffeners. A ring stiffener is arranged at the periphery of the lower section of the protective sleeve.
