Description

Technical Field

[0001] The utility model relates to a fixture for fixing a track sensor, belonging to the field of track equipment. Background Art

[0002] The intellectualization of the railway system has been an important trend in the global railway industry in recent years. It can achieve integrated applications through information technology, big data, artificial intelligence, the Internet of Things and other advanced technologies, greatly improving the efficiency and safety of the railway system. There are two old and new railway networks in the existing railway system. The infrastructure of the old railway system is incomplete. Rebuilding it requires a huge cost and will largely damage the existing railway facilities, and it is impossible to balance the cost of its reconstruction. To solve this problem, a more practical idea is to install a sensing device on the existing railway system to complete the construction of the sensing system without infrastructure installation work, and connect its monitoring, control and maintenance of the track to the new generation railway network, so as to realize the docking and switching between the old and new railway networks.

The track claw is fixed at both ends of the clamping block. The connecting piece connects the clamping block. A step protrusion is arranged on one side of the clamping block, and a track slot is arranged at one end of the track claw. After they are matched and installed, the step protrusion and the track slot are on the same straight line; a sensor installation interface is also arranged on the non-contact surface of the clamping block and the rail.
