Description

A trolley line transition joint for turnout

technical field

The invention relates to the technical field of elevated monorail sightseeing vehicles, in particular to a connection transition joint used for rail girder turnouts of elevated monorail sightseeing vehicles.

Background technique

Elevated monorail sightseeing vehicles (hereinafter referred to as vehicles) generally receive electricity through safety sliding wires, which are laid along the side of the track box-shaped steel beam to ensure continuous and stable power supply during the operation of the vehicle. During the operation of the vehicle, in order to make the vehicle run to different positions, there will be bifurcations in the track beam. When the track is switched at the bifurcation, it is necessary to use a switch (that is, a track switching device that can move in parallel) to achieve smooth track switching during the running of the vehicle. In order to ensure that the vehicle does not interrupt the power supply when passing the switch, the switch section line must also be installed with a safety guide wire. Because the track line is fixed, and the turnout needs to be moved in parallel at any time to change the track, the sliding line of the turnout section and the line sliding line connected to it cannot be directly and permanently connected. It must be easy to adjust and detachable. Use transition joints to connect. At the same time, the size of the transition joint structure cannot exceed the limit requirements of the bogie for the entire line trolley line system, and the transition joint cannot fail or fail due to changes in the environment or operating conditions.
