Description

Technical Field

[0002] Ballastless track is a track structure that uses an integral foundation such as concrete and asphalt mixture to replace the granular gravel roadbed. It is also called ballastless track and is the most advanced track technology in the world today. Compared with ballasted track, ballastless track has the following characteristics: the track structure has good durability and long service life; less maintenance workload and low maintenance cost; good smoothness and high stability, and can maintain the shape and position of the rails for a long time; the noise and vibration generated when the train is running are small, and the ride comfort is high; it is suitable for high-speed driving conditions and can withstand higher speeds. In the current railway construction, more and more ballastless tracks are replacing ballasted tracks.

[0003] Similarly, in order to monitor the operation of the turnout on the ballastless track, a detection device needs to be installed on the turnout of the ballastless track, but the existing mounting bracket used on the ballasted track cannot stably fix the detection device on the track.

[0004] For this purpose, a mounting frame is designed for ballastless track working conditions, which is used for installing detection devices such as sensors. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a sensor mounting bracket under ballastless working conditions, which can conveniently mount the sensor on the ballastless track to monitor the operation of the turnout.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sensor mounting bracket under ballastless working conditions, comprising two support arms and a connecting arm located between the two support arms, the ends of the two support arms extend into a connecting groove below the sensor housing and are threadedly connected by bolts, two support feet are arranged below the support arms, connecting plates are arranged on both sides of the support feet, and connecting holes are arranged on the connecting plates.

[0007] Furthermore, it also includes a support plate, which is located below the support foot. A threaded column with a connection hole is provided on the support plate. The threaded column passes through the connection hole and is threadedly connected to a nut. The support plate is connected to the cement sleepers on the ballastless track through bolts and nuts.

[0008] Furthermore, two connecting arms are arranged between the two supporting arms.

[0009] Furthermore, a reinforcement plate is provided between the supporting legs and the connecting plate.

[0010] Furthermore, the connecting hole is a waist-shaped hole.

[0011] Furthermore, a positioning plate is provided on one side of the supporting pad, and the positioning plate is in contact with the side surface of the cement sleeper.

[0012] Compared with the prior art, the beneficial effect of the utility model is: first, the two ends of the support arm are extended into the connecting groove under the sensor housing, and the support arm and the sensor are connected by bolts and nuts, and then the support plate is positioned on the cement sleeper through the positioning plate on one side thereof, an opening is made on the cement sleeper, and the support plate is fixed to the cement sleeper with bolts and nuts, and then the connecting holes on the connecting plates on both sides of the supporting foot are aligned with the threaded columns on the supporting plate, and then the supporting foot is connected to the supporting plate by nuts and gaskets, and finally the sensor is installed on the ballastless track, so that the operation of the turnout is monitored by the sensor.
