The utility model solves the technical scheme that its technical problem uses：
A kind of reinforcement structure of Rear frame of loader, Rear frame include hinged seat, and the both sides of hinged seat and left crossbeam, the right side are big
One end of beam is affixed, and the other end and tailstock of left crossbeam and right crossbeam are affixed, and left crossbeam and right crossbeam are channel members, left crossbeam
It is oppositely arranged with the channel-section steel opening of right crossbeam, the inner side of left crossbeam and right crossbeam front portion is connected with left plate and right plate, pays car
Frame is between left crossbeam and right crossbeam and affixed with left crossbeam and right crossbeam, the outside of the left crossbeam and right crossbeam be provided with
The corresponding left reinforcing plate of sub frame and right reinforcing plate, left reinforcing plate and right reinforcing plate are rectangular steel plates, and left reinforcing plate and the right side add
Strong plate is respectively equipped with circular hole.
Using the utility model of above-mentioned technical proposal, compared with prior art, beneficial effect is：
Left and right reinforcing plate has very strong plasticity, and reinforcing plate is at sub frame stress point, gathered channel-section steel rigidity and
The plasticity of sheet material so that this structure has rigidity and more preferable plasticity, it is not easy to be broken, reinforcing plate is fitted in the big pair car of stress
On the outside of frame, the circular hole among reinforcing plate increases intensity to increase bonding area, eliminates inner side welding stress, is further strengthened
Plasticity, vehicle frame do not allow easy fracture, increase the bulk life time of vehicle frame.
Further, prioritization scheme of the present utility model is：
The borehole structure of the left reinforcing plate and right reinforcing plate is respectively two, and the center of circle of circular hole is located at left reinforcing plate and the right side
On the longitudinal centre line of reinforcing plate.
The both ends of the left reinforcing plate and right reinforcing plate are respectively equipped with chamfering.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
Refering to Fig. 3, Fig. 4, a kind of reinforcement structure of Rear frame of loader, Rear frame includes hinged seat 1, and the two of hinged seat 1
Side is welded with one end of left crossbeam 2 and right crossbeam 3, and the other end of left crossbeam 2 and right crossbeam 3 welds with tailstock 7, hinged seat 1, a left side
Crossbeam 2, right crossbeam 3, tailstock 7 are welded into a rectangular frame.Left crossbeam 2 and right crossbeam 3 be arranged in parallel, and left crossbeam 2 and the right side are big
Beam 3 is channel members, and the channel-section steel opening of left crossbeam 2 and right crossbeam 3 is oppositely arranged, and the anterior inner side of left crossbeam 2 is welded with left side
Plate 4, the anterior inner side of right crossbeam 3 are welded with right plate 5.
Pass through hinged seat 1 and front frame（Do not show in figure）Connection forms frame assembly.Sub frame 6 is placed in left crossbeam 2 and the right side
Between crossbeam 3, sub frame 6 is located at the middle part of Rear frame, the both sides of sub frame 6 respectively with left crossbeam 2 and the inner side of right crossbeam 3
Plate-side plate welding, interior plate weld with left crossbeam 2 and right crossbeam 3 respectively.The outside of left crossbeam 2 is provided with corresponding with sub frame 6
Left reinforcing plate 8, the outside of right crossbeam 3 are provided with the right reinforcing plate 9 corresponding with sub frame 6, and left reinforcing plate 8 and right reinforcing plate 9 are right
Claim, left reinforcing plate 8 and right reinforcing plate 9 are rectangular steel plates, and the height degree of left reinforcing plate 8 and right reinforcing plate 9 is less than or equal to a left side greatly
