Railway track elastic strip gap detection device and method and railway track equipment

The invention discloses an open seam detection device and method for a railway track elastic strip and railway track equipment, and relates to the technical field of railway track accessories and machines for laying various railways. In the device, a first bracket and a second bracket of a shading bracket are oppositely arranged, and a top shading piece is arranged at the top. The photosensitive element and the light-emitting element are fixed to the opposite sides of the first support and the second support respectively, and the space between the photosensitive element and the light-emitting element can contain the middle lower jaw of the elastic strip. The bottom ends of the first support and the second support are tightly attached to the gauge apron and the steel rail respectively, and when the middle lower jaw is contained between the first support and the second support, light emitted by the light-emitting element can penetrate through a gap between the middle lower jaw and the gauge apron to irradiate t
