Embedded type electric heating railway turnout cushion plate snow melting and deicing device

Abstract

The invention relates to an embedded type electric heating railway turnout cushion plate snow melting and deicing device. The device is characterized in that a groove (9) is longitudinally formed in the bottom of each turnout slide bed board (4), electric heating elements (6) are embedded in each groove (9), a power lead wire (10) is led out of the side face of each groove (9) in the direction close to a turnout core of a corresponding turnout (8), the power lead wires (10) are connected with a rail box (3) through anti-explosion junction boxes (5) fixed to sleepers (7), and the rail box (3) is connected with a remote control switch (1) through a wire (2); and the electric heating elements (6) are electric heating strips, and every three electric heating strips (6) are embedded in the groove (9) of the corresponding turnout slide bed board (4) and connected in parallel. By the adoption of the embedded type electric heating railway turnout cushion plate snow melting and deicing device, accumulated snow and ice of the turnouts are effectively melted, and the device has the beneficial effects of being simple in structure, convenient to install, small in maintenance amount, capable of saving energy and environment-friendly.

Description

technical field [0001] The invention relates to a snow melting and deicing device for a railway turnout, in particular to a built-in electrically heated railway turnout backing plate melting and deicing device. Background technique [0002] The turnout is the key railway equipment for the steering of the train. Whether the turnout is flexible or not is related to the safety of railway transportation. However, in the winter in the northern region, due to low temperature and snowfall, especially the water dripping from the body of the metallurgical transport vehicle after thawing, a large amount of ice is formed between the turnout and the sliding bed, and the point rail of the turnout is frozen and cannot rotate normally, resulting in delays and suspension of railway transportation. , train derailment accidents will also occur in severe cases. The commonly used artificial deicing method is not only labor-intensive, labor-intensive, and inefficient, but also affects the opera...

However, in the winter in the northern region, due to low temperature and snowfall, especially the water dripping from the body of the metallurgical transport vehicle after thawing, a large amount of ice is formed between the turnout and the sliding bed, and the point rail of the turnout is frozen and cannot rotate normally, resulting in delays and suspension of railway transportation. In severe cases, train derailment accidents will occur

The commonly used artificial deicing method is not only labor-intensive, labor-intensive, and inefficient, but also affects the operation of vehicles and threatens personal safety; installing pipelines around the turnouts and using steam to heat deicing methods will generate a lot of fog near the pipelines, affecting Passengers look out for signals, which is not conducive to driving safety; there is also a way to install electric heating elements on the rails to melt ice and snow by heating the rails. Since the heating elements are placed outside, the heat loss is large, and it is easy to be corroded by the external environment and damaged
