Background
In the existing gear and rack driving device of the conventional bridge crane, a rack is arranged on a track, a gear is arranged on an end beam (fixed in position) and is meshed with the rack, and a motor drives the gear to rotate so as to drive the end beam to move on the track; the span of the track cannot be adjusted, the position of the rack changes when the track span changes by a certain amplitude, and under the condition, the span of the end beam is unchanged, so that the gear of the conventional gear and rack driving device cannot be correspondingly adjusted and cannot be applied.
Disclosure of Invention
In order to solve the problem, the utility model provides a use rack and pinion drive arrangement on section of jurisdiction loop wheel machine.
The technical scheme of the utility model:
a gear and rack driving device for a segment crane is arranged on a track, the driving device comprises a motor, a gear and a rack, and the rack is arranged on the track; the driving device also comprises a roller, the roller is arranged on the lower mounting plate, the other side of the rack is propped against the rack, a driving shaft vertically penetrates through the end beam of the segment crane and is connected with the motor and the gear, the motor is matched with the gear and the rack to drive the segment crane to walk on the track, and the roller rolls on the rack;
the driving device takes the hinged shaft as the center of a circle to do circular motion and adjust the relative positions of the gear, the roller and the rack.
The lower mounting plate is heart-shaped, the gear is located in the middle of the lower mounting plate, the articulated shaft is located at one end of the lower mounting plate, and the idler wheel is located at the other end of the lower mounting plate.
The driving shaft is sleeved with a sleeve, the upper end of the sleeve is fixedly connected with the upper mounting plate, and the lower end of the sleeve is fixedly connected with the lower mounting plate.
The utility model has the advantages that the design is reasonable, the structure is simple, when the device is installed, the upper mounting plate directly supports the upper side surface of the end beam of the segment crane, the lower mounting plate is connected through the sleeve, and the connection of the articulated shaft is added, so that the problem of the whole structure is ensured; track gauge changes between the track (section of jurisdiction loop wheel machine track is installed in the shield structure frame, the track gauge change because of actual deviation leads to, and slope when tunnel excavation, have under the turning radius condition, when frame and the articulated function operation of frame, the track gauge takes place under these two kinds of circumstances of certain degree change, the range is very little, although there is the frictional problem of end beam of mounting panel and section of jurisdiction loop wheel machine, nevertheless undeniable, above-mentioned drive arrangement adopts flexonics, can adapt to track span certain range change, guarantee mechanism normal operating, and is not influenced.
