Description
Technical field
The present invention relates to engineering machinery field, especially a kind of drawer type lash adjusting device, crawler crane and
Gap method of adjustment.
Background technology
For small tonnage caterpiller crane, to meet the broad gauge mode requirement of complete machine stability during operation, and overall fortune
Track frame is recoverable when defeated, and complete machine width meets the narrow gauge mode requirement of movement requirement, generally using slotting between vehicle frame and track frame
Enter formula connected mode.And due to the presence of foozle, be necessarily required to leave enough between vehicle frame overhanging beam and track frame side hole
Gap, to ensure that vehicle frame overhanging beam can be inserted smoothly in track frame side hole.But when the presence in enough gaps is for operation
The transmission of load is but very unfavorable between vehicle frame and track frame, and gap can cause crawler body bearing compared with big load, outside vehicle frame
When beam power transmission is at track frame side hole, track frame is laterally inwardly tilted, the cincture dangling on the outside of thrust wheel, no longer carrying or only
The load of very little is born, and the carrying on the inside of thrust wheel is necessarily increased, so as to cause the inner side surface wear of thrust wheel and creeper tread
Aggravation, directly affects the service life of creeper tread and thrust wheel.
In order to control the gap of above-below direction between vehicle frame overhanging beam and track frame side hole, existing usual way has following two
Kind：The first is to install assembled adjustment plate in plane on vehicle frame overhanging beam, although can effectively eliminate gap, but need
Screwed hole of the processing to fixed adjustment plate in plane on vehicle frame overhanging beam, screwed hole can cause vehicle frame overhanging beam inner inlet
And corrosion, so as to influence the service life and operational security of vehicle frame；Secondly, adjustment plate can only stretch out in track frame and be in place
It could be installed during operating position, when track frame needs flexible, it is necessary to first adjustment plate is dismantled, otherwise track frame can not be stretched
Contracting.
The second way is to install bending plate on track frame side's portal plate, although avoid the safety issues such as corrosion,
But certainly existing because of foozle, four in every chassis of the gap of above-below direction between vehicle frame overhanging beam and track frame side hole
Junction certainly exists difference, and the bending plate of single specification is it is difficult to ensure that the everywhere gap per chassis can obtain good tune
It is whole, and confusion when using the bending plate of different size necessarily to cause organization of production and the assembled in situ to use, it is unfavorable for producing
The management at scene and the use of later stage user；Also, if it is desired to it will be adjusted optimally in gap up and down with bending plate, in bending
Plate can only necessarily leave the gap of very little with interplanar on vehicle frame overhanging beam, just must be first by bending plate in flexible track frame
Dismantle, otherwise can not smoothly stretch track frame.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art there is provided a kind of drawer type lash adjusting device, carry out
