Description
Technical field
The present invention relates to engineering machinery field, especially a kind of drawer type lash adjusting device, crawler crane and clearance adjustment method.
Background technology
For little tonnage caterpiller crane, the broad gauge mode requirement of complete machine stability during for meeting operation, and during integral transportation, track frame is recoverable, complete machine width meets the narrow gauge mode requirement of transportation request, usually adopts plug-in type connection mode between vehicle frame and track frame.And due to the existence of manufacturing errors, must need to leave enough gaps between vehicle frame overhanging beam and hole, track frame side, to ensure that vehicle frame overhanging beam can insert in hole, track frame side smoothly.But the existence in enough gaps is very unfavorable for the transmission of load between vehicle frame during operation and track frame, gap can cause crawler body bearing larger load, when the power transmission of vehicle frame overhanging beam is to hole, track frame side place, track frame laterally inwardly tilts, cincture outside caterpillar wheel is imagined, and no longer carry or only bear very little load, and the carrying inside caterpillar wheel must strengthen, thus cause the medial surface of caterpillar wheel and caterpillar block to wear and tear to aggravate, directly affect the service life of caterpillar block and caterpillar wheel.
In order to control the gap of above-below direction between vehicle frame overhanging beam and hole, track frame side, existing usual way has following two kinds: the first plane is installed build-up type adjustment plate on vehicle frame overhanging beam, although effectively gap can be eliminated, the tapped bore on vehicle frame overhanging beam, but plane need processed in order to fixed adjustment plate, tapped bore can cause vehicle frame overhanging beam inner inlet and corrosion, thus affects service life and the operational security of vehicle frame; Secondly, adjustment plate could can only be installed when track frame stretches out and puts in place and be in control position, when track frame needs flexible, must first be dismantled by adjustment plate, otherwise track frame cannot stretch.
The second way installs bending plate on track frame side's portal plate, although avoid the safety issues such as corrosion, but because of certainly existing of manufacturing errors, between vehicle frame overhanging beam and hole, track frame side, the gap of above-below direction certainly exists difference in four junctions of every chassis, the bending plate of single specification is difficult to ensure that the gap, everywhere of every chassis can obtain good adjustment, and confusion when adopting the bending plate of different size that organization of production and site assembly must be caused to use, be unfavorable for the management of production scene and the use of later stage user; Further, if want, with bending plate, optimum regime is adjusted in upper and lower gap, on bending plate and vehicle frame overhanging beam, interplanar must leave very little gap, when flexible track frame, just must first be dismantled by bending plate, otherwise the track frame that cannot stretch smoothly.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of drawer type lash adjusting device, crawler crane and clearance adjustment method are provided, can adjust adaptively according to the size of different gap, improve alerting ability and the comfort feature of use, reduce manufacture difficulty and cost.
