Abstract

The application relates to a mechanical lifting device, comprising: a base, a driving assembly, a rotating shaft and a moving part; a rack is provided on the base; the driving assembly is connected with the rotating shaft, and is used to drive the rotating shaft to rotate bidirectionally; The rotating shaft is provided with a gear that can rotate with the rotating shaft, and the gear is engaged with the rack; the rotating shaft is rotatably installed on the moving part. The device can drive the driving assembly to rise while the moving part rises, for height adjustment.

Description

technical field [0001] The application belongs to the mechanical field and relates to a mechanical lifting device. Background technique [0002] Mechanical lifting devices, especially mechanical lifting devices in the form of pedals, are often used on locomotives. The height of the foot switch can be adjusted according to the height and body shape of the drivers and passengers to increase the comfort of the drivers and passengers and the operability of the locomotive. . [0003] CN106864471A discloses a lifting drive device for a foot switch, including a trigger mechanism and a lifting mechanism. The trigger mechanism includes a height adjustment button, a cable fixing plate assembly, a cable and a cable block, and the lifting mechanism includes an air spring, a linkage mechanism and a guide block. The guide block is connected with the pedal, and the height adjustment button moves downward under pressure, which will cause the displacement of the cable through the rotation o...
