Embodiment 1
[0011] Embodiment 1: with reference to attached figure 1 . The splicing method of the long and short core rails of the horizontal hidden point type, the long core rail 1 and the short core rail 2 are connected by bolts, and the long core rail 1 is closely attached to the short core rail 2, according to the internal 1:4 oblique The horizontal cutting is 4mm, the long core rail 1 is in the range of close contact with the short core rail 2, and the working edge of the long core rail 1 is chamfered at 45°; , close to the long core rail 1, and the tip of the short core rail 2 is about 4mm wide. The difference between the processing technology of the long center rail 1 and the existing technology is that the working edge of the close-fitting section rail head is chamfered at 45°, and the existing technology and equipment can meet the processing requirements. The processing technology of the short center rail is basically the same as that of the existing turnout short center rail,...
Embodiment 2
[0012] Embodiment 2: On the basis of Embodiment 1, the splicing method of the long and short center rails of the horizontal hidden tip type, the long center rail 1 and the short center rail 2 are connected by bolts, and the long center rail 1 is connected with the short center rail 2 For the close-fitting position, cut 2mm according to the inner oblique level of 1:3, the long core rail 1 is within the range of close contact with the short core rail 2, and the working side of the long core rail 1 is chamfered at 45°; the short core rail Rail 2 closely adheres to the outer side of 1:3 oblique, and closely adheres to long core rail 1; the tip of short core rail 2 is about 3mm wide.
Embodiment 3
[0013] Embodiment 3: On the basis of Embodiment 1, the splicing method of the long and short core rails of the horizontal hidden tip type, the long core rail 1 and the short core rail 2 are connected by bolts, and the long core rail 1 is connected with the short core rail 2 For the close-fitting position, cut 5mm according to the oblique horizontal angle of 1:5, the long core rail 1 is within the range of close contact with the short core rail 2, and the working edge of the long core rail 1 is chamfered at 45°; the short core rail The edge of rail 2 is close to the outer 1:5 oblique, which is closely attached to the long core rail 1; the width of the tip of the short core rail is about 5mm.
