Bridge type base plate for frog and using method
The invention relates to a bridge type base plate for a frog, which can act on a harmful space area where the frog is easier to fatigue and damage so as to improve the supporting strength and rigidity of the area of the frog, the bridge type base plate comprises an existing frog base plate, a plurality of existing common frog base plates are designed into a whole bridge type base plate, and the whole bridge type base plate stretches across a plurality of switch sleepers. The bridge type base plate has the advantages that firstly, the bearing area of the base plate to the frog is increased, the overall strength reserve of the frog is increased, and when a switch tie is suspended, the bridge type base plate can provide support for the frog, so that impact damage to the frog is reduced; the reinforcing ribs are arranged at the bottom of the whole bridge type base plate, so that the strength reserve is increased, meanwhile, the elastic deformation caused by the impact effect on the frog is relieved, and the occurrence time of frog damage is delayed; and thirdly, the service life of the frog can be prolonged by 20%-30% through application of the whole bridge type base plate. And the replacement frequency of the frog is reduced, and the cost is reduced.
本发明涉及一种一种能够作用于辙叉更易疲劳受损的“有害空间”区域，进而提高辙叉该区域的支撑强度和刚度的辙叉用桥式垫板，包括现有辙叉垫板，多个现有普通辙叉垫板设计成为一个整块桥式垫板，整块桥式垫板横跨多个岔枕。优点：一是既增大了垫板对辙叉的承载面积，又增加辙叉整体强度储备，当在岔枕发生空吊时，桥式垫板能为辙叉提供支撑，减少辙叉受到的冲击损伤；二是由于整块桥式垫板底部设有加强筋，既增加强度储备，同时又减缓辙叉受到的冲击作用下造成的弹性变形，延缓辙叉伤损发生时间；三是预计该整块桥式垫板的应用可提高辙叉寿命20%‑30%。减少了辙叉的更换次数，降低了成本。
