Abstract

The invention discloses an electric trolley device for a straight track or an arc track. The electric trolley device comprises the track, a mounting bottom plate, a driving motor connected with the mounting bottom plate, a speed reducer connected with the driving motor, a transmission belt arranged on the track, a transmission gear meshing with the transmission belt, two rotating plates arranged at the upper end of the mounting bottom plate, travelling wheels and a transmission mechanism. The two rotating plates are each connected with the mounting bottom plate through a rotating shaft. The rotating shafts and the rotating plates as well as the rotating shafts and the mounting bottom plate are connected through bearings correspondingly. Each rotating plate is symmetrically provided with the two travelling wheels which are symmetrically arranged at the two ends of the track. The travelling wheels are connected to the mounting bottom plate through first brackets and can travel on the track in a rolling mode. The transmission mechanism comprises a driving transmission mechanism body and a driven transmission mechanism body. The driving transmission mechanism body is connected with thespeed reducer, and the driven transmission mechanism body is connected with the rotating shafts. The upper ends of the rotating shafts are connected with the transmission gear. A track trolley of theelectric trolley device can operate stably on the bent track.

Description

technical field [0001] The invention belongs to the field of rail transportation, in particular to an electric trolley device for straight rails or circular arc rails. Background technique [0002] As a rail trolley used to move along a predetermined path, the rail trolley is widely used in various occasions such as inspection, shooting, and transportation. At present, the commonly used track trolleys are mostly used on straight track, but on the arc track with small turning radius, it is easy to gnaw the rail, make it difficult to turn and get stuck. The main reason is that when running on a circular arc track with a small turning radius, the contact state between the front wheel and the rear wheel changes due to the large angle between the contact point of the front wheel and the rear wheel in the direction of the track tangent, and the edge of the wheel will be in contact with the rear wheel. The track has greater friction or even jamming. Due to functional requirements...
