Description

Technical Field

[0001] The invention belongs to the technical field of turnouts, and in particular relates to a railway turnout protection device. Background Art

[0002] As an important equipment for connecting railway lines, turnouts are one of the weakest links in the track. With the development of railway transportation towards high speed and heavy load, the adoption of heavy rails and large-number turnouts, higher requirements are placed on switching equipment. The external locking unit is a device for switching turnouts and reliably locking them.

[0003] Since the external locking unit is an open structure, during locomotive transportation, sand is easily spilled and falls into the gap of the action rod when passing through the turnouts at each station. In actual use, the external locking unit is very sensitive to the invasion of foreign objects. The invasion of foreign objects may increase the switching resistance of the external locking unit, affect the resetting of the turnout, cause mechanical failure, or even jam and make it impossible to switch the turnout. Especially in windy and sandy areas and steep slopes in my country, wind and sand invasion and locomotive sand may cause external locking unit failure. Summary of the invention

The pressure sensor 2 is arranged on the upper wall of the fixed support plate 2 and is arranged between the fixed support plate 2 and the sand-proof plate. A control cavity is arranged in the insulating fixing piece, and the microcontroller is arranged in the control cavity. The warning light is arranged on the upper wall of the insulating fixing piece. The pressure sensor 1 and the pressure sensor 2 are electrically connected to the microcontroller respectively. The pressure sensor 1 and the pressure sensor 2 detect whether the fixed support plate 1 and the fixed support plate 2 are firmly fixed to the sand-proof plate.

[0009] Furthermore, the fasteners include bolts and nuts, and the sand-proof plate is made of 304 stainless steel plate, which has strong toughness and corrosion resistance.
