Abstract

The invention belongs to the technical field of railroad bridges and discloses a cold-resistant railway waterproof telescopic device. The cold-resistant railway waterproof telescopic device is used for solving the problems of falling, water leakage, slag accumulation, water accumulation and difficulty in replacement existing in an existing telescopic device. The cold-resistant railway waterproof telescopic device comprises water retaining tables arranged on adjacent beam bodies respectively. Each water retaining table is connected with angle iron. The angle iron is fixedly connected with shaft sleeves. The two pieces of angle iron are sleeved with a sliding shaft through the shaft sleeves. The middle of the sliding shaft is fixedly provided with a limiting plate. The limiting plate and the two shaft sleeves are provided with buffering devices in a matched mode. The upper ends of the angle iron are provided with a seam striding plate wrapping the sliding shaft, the angle iron, the shaft sleeves and the buffering devices in a matched mode, and the lower end of the seam striding plate is connected with the sliding shaft through a bolt.

Description

technical field [0001] The invention belongs to the technical field of railway bridges, and in particular relates to a cold-resistant railway waterproof telescopic device. Background technique [0002] The railway is the main artery of the national economy, and railway transportation always serves the society and the people. With the rapid development of the national economy, the state entrusts railway transportation with more arduous tasks and higher standards. So far, China's existing railway operating mileage has reached 91,000 kilometers, and there are more than 50,000 bridges with a length of more than 4,000 kilometers. In newly built railways, the total length of bridges accounts for an increasing proportion of the total length of the line. For example, the total length of Beijing-Tianjin intercity railway bridges accounts for about 88% of the total line length, and the total length of Beijing-Shanghai high-speed railway bridges accounts for about 81% of the total li...
