Description

Fixed track spike

Technical Field

The utility model relates to a railway construction equipment field especially relates to a fixed track spike.

Background

Railway tracks, which are referred to as rails, tracks, etc., are mainly used on railways and cooperate with switches to enable trains to travel without steering. Railway tracks are usually made up of two parallel rails which are fixed on sleepers, under which there is ballast. Is fastened by rail supports, fasteners, rail pressing devices, rail clamping plates, elastic strips, rail spikes and other rail accessories. The railway rails are made of steel and can bear larger weight than other materials. Sleepers, also known as sleepers, or sleepers, function to distribute the weight of the rails and the pressure they are subjected to separately, and to maintain a fixed gauge of the rails and to maintain the gauge of the rails. The original wooden pillow is changed into a concrete pillow. The track consists of a track bed, sleepers, steel rails, connecting parts, anti-climbing equipment and turnouts. The rail is cast and expanded into I-shaped rail, the ballast bed is directly laid on the roadbed, and the ballast bed is made of crushed stone, pebble, slag and other materials. Rails, sleepers and track beds are materials with different mechanical properties and are combined in different ways. Generally, the bottom of the track is the track bed, which provides the track with the function of elasticity and drainage. The rails may also be laid on concrete foundations (as is quite common on bridges) or even embedded in concrete.

The track is when laying, and is fixed track and base through the track spike, and current track spike has two shortcomings when using: firstly, current track spike is easy fracture or inflation when gas changes winter, leads to track spike's fixity ability to descend, causes the rail to break away from very easily and causes the incident even, and secondly current track is fixed to rely on track spike fixed, makes track spike's bearing capacity require highly, leads to track spike's life to descend easily, and the maintenance cost is higher.
