Description
Technical field
A kind of convenience be the utility model is related in the quick maintenance of equipment of crawler belt that building-site assembles, belong to engineering machinery skill
Art field.
Background technology
In today of urban construction high speed development, the usage quantity of engineering machinery is very huge, on this basis engineering machine
The maintaining quantities of tool is also very huge, and particularly engineering machinery can often work overloadingly, and causes engineering mechanical maintenance more
Add frequently.Existing engineering machinery is more using crawler belt as running gear simultaneously, during the use of crawler belt, because of senile abrasion reason
Often occurring that Chain Link is broken, situations such as big, is ground in bearing pin breakdown, bearing pin mill chainlet rail knothole footpath, causes complete machine to walk,
It can not work, just need to change Chain Link in the case.
Problems be present during Chain Link is changed：
1st, because bearing pin and Chain Link using interference fit, the magnitude of interference reach 0.2-0.4mm, this bearing pin in theory on this basis
Connection hydraulically need to dismantle and assemble, but influenceed and maintenance cost by working environment, take and return factory and be typically not easy to realize,
Existing mostly to be changed using barbarous mode, method is mostly that first knothole is heated using welding gun, becomes aperture expansion
Greatly, then with more than 18 pounds of sledgehammer bearing pin is added by force, due to limited personnel, the magnitude of interference is big in addition, it sometimes appear that bearing pin head
Portion beaten it is swollen after, do not reach defined fitted position.
2nd, the diameter of bearing pin is changed small, reduces the magnitude of interference, then squeezed into sledgehammer, and by bearing pin both ends electric welding,
Because the magnitude of interference reduces, stressing conditions are changed, after 2-3 months, with the fracture of weld seam, bearing pin freely turns in knothole
It is dynamic, dropped out out of knothole, cause equipment can not normal operation, utilization rate degradation.
Above-mentioned maintenance mode there is problems simultaneously
A, labor intensity is big, and need to wave sledgehammer with the maintenance personal of physically alive could squeeze into bearing pin in knothole；
B, after knothole is swollen using heating, because chain link is by high temperature, after material changes, often from heating
Place's fracture；
C, Chain Link is assembled with the mode for reducing the magnitude of interference and welding, because changing former design, unbalance stress, and makes bearing pin
Rotate and slide in knothole, prevent equipment from walking；
D, after bearing pin rotates in knothole, phase mutual friction, aperture is made to become big, the diameter of axle diminishes, and fracture is produced after heating, is caused
A whole set of Chain Link is scrapped, and considerably increases production cost；
E, because service life shortens, repair and change frequently, can seriously have impact on construction speed, be carried so as to generate owner
Before move back machine, the duration produces the consequence of hysteresis.
