Reinforced freezing clamping plate for railway
The invention relates to a railway track machining technology, and aims to provide a reinforced freezing clamping plate for a railway. A long-strip-shaped body of the product is provided with an inner side face matched with the side face of a steel rail in shape, and a plurality of transversely-penetrating bolt holes are formed in the middle of the body in the length direction at intervals. An upper reinforcing rib and a lower reinforcing rib which are parallel to each other are arranged on the outer side face of the freezing splint body in the length direction of the freezing splint body and are equal to or basically equal to the freezing splint body in length. Wherein the lower side reinforcing rib comprises a relatively thick part located in the middle and relatively thin parts located at the two ends, and the length of the relatively thick part in the middle accounts for 2/3-1/4 of the total length of the lower side reinforcing rib. The problem that in the prior art, the middle of a freezing clamping plate is prone to metal fatigue to cause fracture is solved; flexural rigidity of two ends of the clamping plate can be correspondingly reduced, and material cost is saved; the device can be tightly attached to the rail web, full-section contact is achieved, and friction resistance is improved.
本发明涉及铁路轨道加工技术，旨在提供一种铁路用加强型冻结夹板。该产品的长条形本体具有适配钢轨侧面形状的内侧面，在本体的中部沿长度方向间隔设有横向贯穿的多个螺栓孔；在冻结夹板本体的外侧面，沿其长度方向设有相互平行的上侧加强筋和下侧加强筋，两者与冻结夹板的本体等长或基本等长；其中，下侧加强筋包括位于中部的相对较厚部分和位于两端的相对较薄部分，且中部较厚部分的长度占其总长度的2/3～1/4。本发明解决了现有技术中冻结夹板中间易金属疲劳导致的断裂病害；可以相应降低夹板两端抗弯刚度，节约材料成本；能够与钢轨轨腰密贴，实现全断面接触，提高摩擦阻力。
