New anti-failure damper and its installation method

Abstract

The invention relates to the technical field of safety protection at the end of rail transit trains or train lines, in particular to a damper structure for safety protection of large marshalling trains and high-speed trains. The box body of the present invention is composed of two semi-boxes with symmetrical structures: after the two half-boxes are merged, the upper part forms a complete cavity with an open bottom, and the lower part forms an installation tank with the same cross-sectional shape as the rail head and the rail waist; There is at least one horizontal screw hole on the side wall of the installation cavity of the half box; the eccentric body bolt is installed on the screw hole, and there is a long eccentric body bolt in the middle, and the fixed threads on both ends of the bolt are positive and negative. Threaded structure; nuts are installed on the fixed threads at both ends of the eccentric body bolts for installation and clamping of the box; the friction plate is a long strip structure, installed inside the installation cavity, between the rail head and the eccentric body bolts Between. The technical solution of the present invention solves the problems in the prior art: 1. After sliding for a certain distance, the damper fails; 2. The number of dampers is too large, which increases the budget; 3. The equipment is heavy and inconvenient to install.

Description

technical field [0001] The invention relates to the technical field of safety protection at the end of rail transit trains or train lines, in particular to a damper structure for safety protection of large marshalling trains and high-speed trains. Background technique [0002] The stop device at the end of the track line is generally equipped with a damper to consume the impact kinetic energy of the train. With the improvement of the safety protection level, it is often necessary to realize parking within a short distance, and it is necessary to increase the number of dampers to meet the parking requirements. It is necessary to increase the reserved length and increase the budget when designing the line. The number of damper arrangements is limited by the reserved length of existing lines. [0003] Most existing dampers are designed to clamp the rail on both sides of the transverse bolts, and the upper end is vertically pressed by the bolt to the friction plate at the upper...

AI Technical Summary

Problems solved by technology

However, after sliding for a certain distance, due to the wear and elastic deformation of the friction plate, the loosening of the bolts, and the failure of the bolts under stress for a long time, and even the deformation and wear of the rail, the positive pressure of the friction plate and the clamping force of the damper will appear. Lower or disappear, causing the damper to lose its effect

[0004] Most existing damper equipment is bulky and easy to install
