The utility model content
The purpose of the utility model is to overcome the deficiency of prior art, provide a kind of connect stable, can anti shock and vibration, long service life, can guarantee the turnout guard rail structure of train driving safety.
To achieve these goals, the technical scheme of the utility model employing is:
Said turnout guard rail structure is located at a side of stock rail, comprises fagging and guard rail, and said guard rail is connected through bolt with a side on said fagging top; Said guard rail and stock rail are oppositely arranged; Be provided with backing plate in the fagging bottom, below backing plate, be provided with elastomeric pad; One end of elastomeric pad is positioned on the stock rail bottom; The side that said fagging is connected with said guard rail is the inclined-plane horizontal by angle, the ramp structure of the side that said guard rail is connected with fagging for matching with said inclined-plane.
The angle of said fagging and said guard rail connection inclined and horizontal plane is less than 90 degree.
One end of said bolt passes guard rail, on the end that bolt passes, is provided with the nut adaptive with bolt, on the external surface of said nut, is set with nut sleeve, said nut sleeve and guard rail welding.
Said nut is a hex nut, and said nut sleeve is interior hexagonal structure, said nut sleeve on the hexagonal position with said guard rail spot welding.
The advantage of the utility model is: said turnout guard rail structure, and a side that is connected with guard rail through fagging is set to the inclined-plane horizontal by angle, and the side that guard rail is connected with fagging is set to the ramp structure that matches with the inclined-plane; Be equivalent to a part is cut away along the horizontal plane incline direction in the top of fagging, the part that corresponding guard rail increases is identical with the part that fagging cuts away, and the newly-increased part of fagging and guard rail constitutes original fagging; Cooperate through the inclined-plane between guard rail and the fagging, use bolted mode again, the connective stability between the two can be improved, and the power that train acts on the guard rail is transferred to fagging with part; Can improve the impact resistance of guard rail, effectively reduce the degree of wear of guard rail, prolong the application life of guard rail, guarantee the driving safety of train; Simultaneously, the utility model is simple in structure, assembles easy to usely, and cost of manufacture is low.
