Composite drive conversion device for track and track system thereof

Abstract

The invention discloses a composite drive conversion device for a track and a track system thereof. The composite drive conversion device for the track comprises a movable end of a pin tooth row, a fixed end of the pin tooth row, a fixed pin shaft, left and right torsion springs, a U-shaped support plate, a pin The movable end of the tooth row rotates in one direction with the fixed pin shaft as the fulcrum, and the automatic conversion and calibration of the friction drive and the gear meshing drive can be realized by adjusting the angle of the movable end of the pin tooth row. The track system includes a track equipped with a compound drive conversion device and a common track unit without a pin-tooth row. When the track is used for horizontal or near-horizontal working conditions, the ordinary track unit is installed, and the other working conditions are installed with Track unit for compound drive conversion devices. The design adopts modular design, and the interchangeability between each track unit is good. Therefore, the track system has good adaptability, and the type of track unit required can be replaced at any time according to different working conditions. The composite drive conversion device in the track system is simple in structure and convenient in operation, and cleverly avoids the rigid collision between the gear and the pin-tooth row, and prolongs the service life of the gear.

Description

technical field [0001] The invention relates to the field of track machinery, in particular to the field of track drive. Background technique [0002] There are generally two methods for the existing monorail crane compound driving device. Method 1: install gears on the top of the ordinary horizontal driving wheel, and weld the rack horizontally above the track, and the width of the rack is much larger than the width of the track. When the driving part of the monorail crane travels to the track with rack, due to the large width of the rack, the drive group will be stretched. At this time, the hydraulic system will automatically sense the pressure change and release the pressure at the same time, so that the gear and the rack can be engaged. Movement, thereby replacing friction drive with rack and pinion engagement. The opposite is true when driving off the rack. The disadvantage of this type of rack auxiliary device is that when the monorail crane enters the rack, the pres...

Problems solved by technology

This device also uses a hydraulic cylinder to realize the engagement and separation of the gear mesh, and must be operated manually, and there will be a rigid impact at the moment of mesh engagement, which will shorten the service life of the gear
