Rail-mounted inspection robot with autonomous rail transfer function

Abstract

The invention discloses a rail-mounted inspection robot with an autonomous rail transfer function. The rail-mounted inspection robot comprises a transverse moving system, two grabbing and attaching systems connected to the transverse moving system and a power system. The grabbing and attaching system moves along with the transverse moving part corresponding to the transverse moving system, rail transfer operation is achieved, the power system achieves rail transfer along with synchronous driving of the two transverse moving parts of the transverse moving system, and therefore rapid rail transfer of the power system is achieved; after rail transfer, the driving wheels of the power system are driven by the driving motor to rotate so that the power system can drive the whole rail-mounted inspection robot to achieve the rail inspection function. The rail-mounted inspection robot can complete autonomous rail transfer without changing the rail structure or adding an auxiliary rail transfer device; the distance between the two clamping jaws of the grabbing and attaching system is adjusted to adapt to rails with different widths, the transverse moving length of the transverse moving systemis changed to adapt to the rail transfer distance, and wide applicability is achieved.

Description

technical field [0001] The invention relates to the technical field of track-type inspection robots, in particular to a track-type inspection robot with the function of autonomous track change. Background technique [0002] As a key link connecting electric locomotives and rail transit power supply systems, the catenary system is the main source of electricity for subway trains. The rigid catenary has certain advantages over the flexible catenary in the tunnel. Its contact line has no tension, no anchoring device is needed, and there will be no disconnection accidents. It has fewer parts, large carrying capacity, safety and reliability, and small maintenance workload. Features, are widely used in subway tunnels. Due to the harsh working environment and long-term work under vibration conditions, the support, positioning, suspension and other devices of the rigid catenary are prone to problems such as loosening, falling off or damage. If it is not discovered and dealt with i...

Problems solved by technology

However, the current track-based inspection robot can only conduct inspections along a specific section of track, and cannot perform multi-track track change inspection tasks; or it needs an auxiliary track change device to be installed on the track to achieve track change
