Summary of the invention
To be solved in the utility model is that existing wheel loader vehicle frame latch-up structure is complicated, and welding procedure is loaded down with trivial details, the technical problem that operating procedure is not easy.
In order to solve the problems of the technologies described above, the utility model provides a kind of wheel loader vehicle frame latch-up structure, and the fixed end of fixed bar is connected with front frame, it is characterized in that, front frame is provided with for the fixing fixed head of fixed bar movable end; Fixed end and the front frame of fixed bar are rotationally connected by bearing pin; The lower articulated slab of rear vehicle frame is provided with jack one; The movable end of fixed bar is bending structure, and when the movable end of fixed bar is connected with rear vehicle frame, movable end is arranged in jack one, and the part that movable end exposes from jack one is provided with pin-and-hole one, in pin-and-hole one, is provided with cottor pin; When the movable end of fixed bar is fixed in front frame, on fixed bar, corresponding fixed head place is provided with projective structure, in the jack two of projective structure from fixed head, exposes, and exposed portions serve is provided with pin-and-hole two, in pin-and-hole two, is provided with cottor pin.
Preferably, one end of described bearing pin is larger end, and the other end is compared with small end, and larger end is positioned at the outside of front frame, compared with small end, from fixed bar, exposes, and exposed portions serve is provided with draw-in groove, is provided with back-up ring in draw-in groove.
Front frame welding bearing pin and fixed head, articulated slab perforate under rear vehicle frame, when loader is static, insert in front frame bearing pin fixed bar one end, has draw-in groove, thereby on draw-in groove, pack fixedly this end of fixed bar of back-up ring on bearing pin, after fixed bar movable end inserts under vehicle frame in hinged plate hole, and cottor pin is penetrated in fixed bar hole, thereby it is movable to limit fixed bar, prevents that vehicle frame from rotating; When loader operation, extract cottor pin, rotate fixed bar to front frame fixed head place, fixed bar projective structure to be inserted in fixed head perforate, cottor pin is inserted in the pin-and-hole of fixed bar projective structure, thus locking fixed bar.
The utility model has the advantage of: simple in structure, technique, easy to operate, low cost of manufacture.

The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Fig. 8-12, the structural representation of a kind of wheel loader vehicle frame latch-up structure providing for the utility model, one end of fixed bar 4 is fixed end, the other end is movable end 9.The fixed end of fixed bar 4 is connected with front frame 1, installs one for the fixing fixed head 8 of fixed bar 4 movable ends 9 in front frame 1, opens jack 2 14 on fixed head 8.The fixed end of fixed bar 4 and front frame 1 are rotationally connected by bearing pin 3, insert bearing pin 3 after the pin shaft hole on fixed bar 4 fixed ends is aimed at the pin shaft hole in front frame 1, make fixed bar 4 can be close to front frame 1 and are rotated.One end of bearing pin 3 is larger end, and the other end is compared with small end, by insert successively the fixed end of front frame 1, fixed bar 4 compared with small end, compared with small end, from fixed bar 4, exposes, and exposed portions serve is provided with draw-in groove 15, puts a back-up ring 2 fixing in draw-in groove 15.The lower articulated slab 5 of rear vehicle frame 7 is opened jack 1; The movable end 9 of fixed bar 4 is bending structure.When the movable end 9 of fixed bar 4 is connected with rear vehicle frame 7, movable end 9 inserts in jack 1, the part expense hole 1 that movable end 9 exposes from jack 1, the interior insertion cottor pin 6 of pin-and-hole 1; When the movable end 9 of fixed bar 4 is fixed in front frame 1, on fixed bar 4, corresponding fixed head 8 places are provided with projective structure 11, in the jack 2 14 that projective structure 11 inserts on fixed head 8, the part expense hole 2 14 of exposing from jack 2 14, inserts pin-and-hole 2 14 by cottor pin 6.
When loader is static, fixed bar 4 movable ends 9 insert in the jack 1 of rear 7 times articulated slabs 5 of vehicle frame, and cottor pin 6 is penetrated in pin-and-hole 10, thereby limit fixed bar 4 activities, prevent that vehicle frame from rotating; When loader operation, extract cottor pin 6, rotate fixed bar 4 to front frame 1 fixed head 8 places, the projective structure of fixed bar 4 11 to be inserted in the jack 2 14 of fixed head 8, cottor pin 6 is inserted in pin-and-hole 2 12, thus locking fixed bar 4.
Wherein, fixed bar 4 is simple in structure, and directly cutting stock forms; Lower articulated slab 5 (as shown in Figure 9) has the jack 13 that fastens fixed pole 4 movable ends 9; Fixed head 8 (as shown in Figure 10-11), completes through blanking bending, simple to operation; Bearing pin 3 (as shown in figure 12) is simple in structure, easy to process, has draw-in groove on axle, with back-up ring 2, can fix.
