The rear mounting plate of vehicle frame abuts against, and the counterweight ontology is respectively equipped in grafting notch two sides and protrudes into the grafting notch
Lapping plate, two pieces of lapping plates ride over respectively on the overlap joint load bearing support plate of the vehicle frame two sides；The counterweight ontology is logical
Excessive connect from the bolt that rear sequentially passes through the counterweight ontology and the rear mounting plate with the vehicle frame.
Further: the more bolts are respectively four main installation bolts and two secondary installation bolts.
It is further: the master of the main installation bolt is installed there are four setting on mounting surface before the counterweight of the grafting notch
Through-hole and two install the secondary through-hole of the secondary installation bolt；Two secondary through-holes are pacified before being located at the counterweight of the grafting notch
The middle part in dress face, four main through-holes are located at around two secondary through-holes.
It is further: to set that there are four main installation spiral shells corresponding with the main through-hole respectively on the rear mounting plate of the vehicle frame
The secondary installation threaded hole corresponding with the secondary through-hole respectively of pit and two.
For above-mentioned wheel loader in counterweight technology scheme, more specific technical solution may also is that a kind of wheeled loading
The installation method of machine counterweight, wheel loader counterweight include the counterweight ontology equipped with grafting notch, the counterweight ontology
Grafting notch is equipped with mounting surface before counterweight, and the counterweight ontology is respectively equipped in grafting notch two sides and protrudes into the grafting
Lapping plate in notch is equipped with multiple main through-holes and multiple secondary through-holes before the counterweight of the grafting notch, uses on mounting surface
A kind of vehicle frame, the vehicle frame have corresponding with mounting surface before the counterweight in the counterweight mounting portion of tail portion, the counterweight mounting portion
Rear mounting plate and be located at the overlap joint load bearing support plates of two sides, it is described after mounting plate be equipped with it is multiple logical with the master respectively
The corresponding main installation threaded hole in hole and multiple secondary installation threaded holes corresponding with the pair through-hole respectively, wheel loader
With the installation method of counterweight the following steps are included:
A, the counterweight mounting portion of the grafting notch of the counterweight ontology towards the vehicle frame is promoted, makes grafting notch two sides
Lapping plate is mutually overlapped with the overlap joint load bearing support plate respectively, mounting surface and the rear mounting plate before the counterweight of the grafting notch
It abuts against；
B, the more main installation bolts are inserted into multiple main through-holes respectively from counterweight ontology rear, by more institutes
Secondary installation bolt is stated to be inserted into respectively in multiple secondary through-holes from counterweight ontology rear；
C, start air pressure gun, successively fasten the more main installation bolts and the more secondary installation bolts are completed.
Further: the main through-hole is four, and the pair through-hole is two；Two secondary through-holes are located at the grafting
The middle part of mounting surface before the counterweight of notch, four main through-holes are located at around two secondary through-holes.
By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages: due to counterweight
Ontology solves spiral shell on the overlap joint load bearing support plate that grafting notch two sides are equipped with lapping plate and ride over vehicle frame two sides by lapping plate
The risk that bolt loosens；Counterweight ontology passes through the bolt of counterweight ontology and rear mounting plate from rear by more simultaneously and vehicle frame connects
It connects, can make the fastening of bolt that need to only fasten from a direction, saving of work and time simplifies assembly technology, improves assembly efficiency.
