Fastener device for turnout and turnout
The embodiment of the invention provides a fastener device for a turnout, the fastener device comprises an upper base plate, a lower base plate, a positioning sleeve and a transverse elastic piece, the upper base plate is provided with a first abutting surface and a first positioning hole penetrating through the upper base plate in the thickness direction of the upper base plate, and the first abutting surface faces the transverse side of the upper base plate; the lower base plate is stacked below the upper base plate, the lower base plate is provided with a second abutting surface and a positioning protrusion protruding out of the top surface of the lower base plate, and the second abutting surface is located on the transverse side of the first abutting surface; the positioning protrusion is inserted into the first positioning hole, and the positioning sleeve is arranged on the positioning protrusion and clamped between the positioning protrusion and the inner wall of the first positioning hole. The transverse elastic piece is clamped between the first abutting surface and the second abutting surface and can stretch out and draw back in the transverse direction. According to the fastener device, transverse vibration energy is absorbed through the transverse elastic piece, transverse vibration impact between the upper base plate and the lower base plate is reduced, noise is reduced, and the line maintenance workload and cost are reduced.
本发明实施例提供一种用于道岔的扣件装置，扣件装置包括：上垫板、下垫板、定位套和横向弹性件，上垫板设有第一抵接面和沿上垫板的厚度方向贯穿上垫板的第一定位孔，第一抵接面朝向上垫板的横向一侧；下垫板叠置于上垫板的下方，下垫板设有第二抵接面和凸出于下垫板的顶表面的定位凸起，第二抵接面位于第一抵接面的横向一侧；定位凸起插入到第一定位孔中，定位套设于定位凸起上且夹设于定位凸起和第一定位孔的内壁之间；横向弹性件夹设于第一抵接面和第二抵接面之间，横向弹性件可以沿横向伸缩。本发明实施例中的扣件装置通过横向弹性件吸收了横向振动能量，降低了上垫板和下垫板之间的横向振动冲击，减小了噪声、减轻了线路维护工作量和成本。
