Background technology
The articulated front frame of loading machine is usually case structure, and its top board has dump ram bearing and swing arm bearing, And the biside plate of front frame casing is provided with elevating ram pin shaft hole, therefore dump ram, swing arm and elevating ram are all connected with In front frame, in operation process, front frame will bear the larger load of different directions to loading machine, especially elevating ram, It is supported on the biside plate of front frame, therefore biside plate needs to bear elevating ram to be delivered to the larger load of front frame, is The strength and stiffness of front frame biside plate are improved, a kind of structure is strong to improve side plate in biside plate increase polylith reinforcing plate structure Degree and rigidity, another structure strengthen strength and stiffness etc. by thickening the thickness and the strength of materials of biside plate, but above-mentioned All there are steel using on the high side in two kinds of structures, be not easy to manufacture, especially be upwardly deviated from articulated slab in elevating ram pin shaft hole larger When, the strength and stiffness of the front frame structure more difficult effect for having obtained is to reduce front frame the problems such as elevating ram inconvenient maintenance Weight, be also respectively fixed with otic placode on the outer wall of biside plate, although elevating ram pin shaft hole, but side also are provided with otic placode After plate stress, can still there is the risk that ftractures, therefore the stress problem of biside plate can not be fully solved, therefore, we Propose a kind of front frame for loader.
Utility model content
The purpose of this utility model is and a kind of loading machine front truck for proposing in order to solve shortcoming present in prior art Frame.
To achieve these goals, the utility model employs following technical scheme:
A kind of front frame for loader is designed, including front and rear part has the casing of opening, the casing is provided with upper frame component With two side plates, positioned at the both sides of upper frame component, the upper end of the upper frame component is provided with to install tipping bucket two side plates Casing rear portion described in the dump ram bearing of oil cylinder is provided with hinged seat, and the hinged seat includes upper articulated slab and lower articulated slab, institute State articulated slab and lower articulated slab is each attached on casing, and the hinge hole that is provided with of upper articulated slab and lower articulated slab are provided with Hinge hole on the same line, is respectively and fixedly provided with L-shaped otic placode, and two side plates and two on two lateral walls of the side plate Elevating ram seat and swing arm bearing are equipped with otic placode, the swing arm bearing is located at the top of elevating ram seat, the lifting oil Cylinder seat is provided with to install the elevating ram pin shaft hole of elevating ram, the bottom of two otic placodes and two outer walls of side plate On be fixed with supporting plate, the madial wall of two side plates and the upper end of upper articulated slab are fixed with gusset, the tail of the upper articulated slab Portion is provided with arc, and reinforcing plate is fixed with the upper frame component and two outer walls of side plate.
Preferably, the upper frame component is box-structure.
The utility model proposes a kind of front frame for loader, beneficial effect is:The utility model operation when, the dress Carrier aircraft front frame, by increasing the reinforcing plate and the gusset that are mutually permanently connected between biside plate madial wall and biside plate, On the premise of front frame steel usage amount is minimum so that front frame has intensity and rigidity higher, it is not only convenient for manufacturing, And the whole housing interior volume of front frame is bigger, it is easy to maintenance and the arrangement of other systems.
Brief description of the drawings
Fig. 1 be the utility model proposes a kind of front frame for loader structural representation;
Fig. 2 is the A-A cross section structure diagrams of Fig. 1;
Fig. 3 is the side structure schematic view of Fig. 1.
In figure:Side plate 1, dump ram bearing 2, upper frame component 3, swing arm bearing 4, reinforcing plate 5, otic placode 6, elevating ram seat 7th, supporting plate 8, gusset 9, arc 10, upper articulated slab 11, lower articulated slab 12.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.
Reference picture 1-3, a kind of front frame for loader, including front and rear part have the casing of opening, and casing is provided with upper frame conjunction Part 3 and two side plates 1, upper frame component 3 are box-structure, and upper frame component 3 is set to box-structure and can preferably play connection two The effect of side plate 1 and support dump ram, so that the top board ability for replacing one piece traditional of top plate type front frame needs very thick is complete Into function, two side plates 1 are located at the both sides of upper frame component 3, and the upper end of upper frame component 3 is provided with to install turning over for dump ram Bucket cylinder support 2, casing rear portion is provided with hinged seat, and hinged seat includes upper articulated slab 11 and lower articulated slab 12, the He of upper articulated slab 11 Lower articulated slab 12 is each attached on casing, and the hinge hole that the hinge hole that is provided with of upper articulated slab 11 and lower articulated slab 12 are provided with On the same line.
