A plurality of electric wheels are arranged at the bottom of the transport vehicle and arranged on the outer walls of the first connecting rail and the second connecting rail correspondingly, a supporting plate is fixedly connected to the bottom of the transport vehicle, a plurality of supporting shafts are rotationally connected to the bottom of the supporting plate, pulleys are rotationally connected to the outer walls of the supporting shafts correspondingly, and the pulleys are arranged on the two sides of the fixed rail correspondingly. Fixing assemblies are arranged on the top of the transport vehicle. Modularized assembly of the fixed rail, the first connecting rail and the second connecting rail is convenient to disassemble and assemble, a power supporting system of the electric wheels and the pulleys of the transport vehicle guarantees transport stability, and the fixed assembly achieves mechanical locking of the photovoltaic assembly to prevent transport displacement.

The utility model discloses a variable-pitch power line patrol vehicle, and belongs to the technical field of power line patrol equipment. The device comprises a mobile platform and a sensor module loaded on the mobile platform and used for line inspection, and further comprises a driving wheel assembly which comprises a mounting plate, a driving mechanism fixed on the mounting plate, a driving wheel located on the side face of the mounting plate and fixed to a rotating shaft of the driving mechanism, and a pair of follow-up guide wheels located on the two sides of the driving wheel; and the telescopic assembly is provided with a telescopic end which stretches and retracts towards one side or two sides, and the telescopic assembly is fixed on the movable platform. According to the line patrol vehicle, the distance between the left and right driving wheel assemblies is variable through the telescopic assembly; in addition, the driving wheel assembly is provided with a pair of follow-up guide wheels arranged on the two sides of the bridge guide rails respectively, when the distance between the bridge guide rails fluctuates, the bridge guide rails can extrude the follow-up guide wheels, the follow-up guide wheels drive the telescopic ends of the telescopic assemblies to move, and the purpose of stably passing on the bridge guide rails with continuous track gauge changes is achieved.

The present application belongs to the field of rail transit technology, and specifically provides a suspension rail transit turnout reversing system, which comprises a track and a vehicle body, the track is provided with a turnout at a branch, the vehicle body is provided with a control unit, the turnout is arranged on the inner wall of the track on both sides, the vehicle body is provided with a rail changing device, the rail changing device comprises a driving unit, a connecting frame and a rail changing wheel, the connecting frame connects the rail changing wheel on both sides of the vehicle body, so that the rail changing wheel can run on the inner wall of the track and cooperate with the corresponding side turnout; the driving unit is in communication connection with the control unit and drives the connecting frame to act, so that the rail changing wheel can move away from the corresponding side turnout; in the present application, the rail changing wheel is arranged on both sides of the vehicle body, does not occupy the roof space, reduces the height of the vehicle body and the track beam, and reduces the manufacturing cost; when the vehicle body runs on a non-turnout, the rail changing wheels on both sides are close to the inner wall of the track, effectively suppresses the lateral swing, and improves the driving stability; when the vehicle body runs on a turnout, only the rail changing wheel on the side opposite to the turning direction needs to act, and the rail changing wheel on the other side needs to keep cooperating with the turnout, so that the rail can be changed.
