Problems solved by technology

The design of this kind of track components is complicated, the volume increases, it is difficult to realize the repeated use of the device, the production cost is high, and the maintenance cost is high. The combination of different gauge rails needs to be redesigned and calculated. There may be two kinds of rails. The distance difference is too small to place four fasteners, so that fasteners cannot be placed between two adjacen

Abstract

The invention relates to a rail set railway fixing device. A rail set is a three-way rail set and comprises a common rail, a left non-common rail and a right non-common rail, an iron backing plate isinstalled between the bottoms of the left non-common rail and the right non-common rail and a rail set sleeper, and the top face of the iron backing plate is in a ladder shape; a fastening device is fixedly installed between the left non-common rail and the right non-common rail; and a fastener A is installed on the outer side of the rail bottom of the left non-common rail, a fastener B is installed on the outer side of the rail bottom of the right non-common rail, and the fastener A and the fastener B are arranged in a staggered or symmetric mode. The rail set railway fixing device is low inproduction cost, convenient to maintain and high in safety.

Description

technical field [0001] The invention relates to a fixing device for a casing railway. Background technique [0002] In recent years, with the continuous development of my country's national economy, the economic exchanges with neighboring countries have become more and more frequent, and the foreign trade volume has continued to grow. As the most important channel connecting our country and surrounding countries, international railway plays an increasingly important role in accelerating the development of trade between countries and strengthening the economic construction of border areas. In recent years, the traffic volume of my country's railway port stations has made great progress, and several major port stations have been or are undergoing large-scale reconstruction and expansion projects to meet the ever-increasing needs of passenger and freight traffic. In order to meet the continuous demand for raw materials for my country's economic development and strengthen econo...
