Rail crossing type frog
The invention relates to the technical field of railway frogs, and provides a rail crossing type frog which comprises a main line steel rail. The toe end lifting frog is arranged on the outer side of the main line steel rail, the toe end lifting frog is provided with a first guide slope, the height of the first guide slope is gradually increased from the end away from the main line steel rail to the end close to the main line steel rail, and the first guide slope is used for abutting against a rail changing wheel; the heel end lifting frog is arranged on the inner side of the main line steel rail, included angles are formed between the toe end lifting frog and the heel end lifting frog and the main line steel rail, a supporting table is arranged on the side, close to the main line steel rail, of the heel end lifting frog, and a passing space is formed between the supporting table and the main line steel rail and used for straight wheels to pass through. The rail changing wheels abut against the supporting table after crossing the main line steel rail. By means of the technical scheme, the problem that in the prior art, a crossing frog is complex in structure and inconvenient to maintain is solved.
本发明涉及铁路辙叉技术领域，提出了一种越轨式辙叉，包括主线钢轨；趾端抬升辙叉设置在主线钢轨外侧，趾端抬升辙叉具有第一导向斜面，第一导向斜面从远离主线钢轨一端到靠近主线钢轨一端高度逐渐升高，第一导向斜面用于与换轨车轮抵接；跟端抬升辙叉设置在主线钢轨内侧，趾端抬升辙叉和跟端抬升辙叉与主线钢轨之间具有夹角，跟端抬升辙叉靠近主线钢轨一侧具有支撑台，支撑台和主线钢轨之间形成通过空间，通过空间用于直行车轮通过，换轨车轮越过主线钢轨后与支撑台抵接。通过上述技术方案，解决了现有技术中的乘越式辙叉结构复杂不便维护的问题。
