Description
Technical field
The present invention relates to a kind of wheel loader bicycle frame lock fixed structure, belong to the loader technical field.
Background technology
Wheel loader is a kind of Engineering Work machine that shovels the material shipment, be widely used in the infrastructures such as city, traffic, water conservancy, the bicycle frame lock fixed structure of wheel loader is mostly as shown in Fig. 1-7 in the market, the front side of front frame 1 is provided with the lock 1 of monolithic, rear side is provided with lock 2 17, and lock 2 17 is comprised of spaced monolithic lock between two; Rear vehicle frame 7 is provided with the lock 3 18 of monolithic; One end of fixed bar 4 is fixed end, and the fixed end of fixed bar 4 is connected with front frame 1, and fixed bar 4 comprises connecting rod 41, and an end of connecting rod 41 is provided with pin shaft hole, and the both sides of the other end are respectively equipped with a junction plate 42, and every junction plate 42 is provided with pin shaft hole; Connecting rod 41 is provided with an end of pin shaft hole and is located in the interval of lock 2 17, and bearing pin 3 is arranged in lock 2 17 and connecting rod 41, and an end of bearing pin 3 is annulus, and the other end exposes in lock 2 17, and this bared end is provided with cottor pin 6; The end that fixed bar 4 is provided with junction plate 42 is connected by a bearing pin 3 equally with lock 1 or lock 3 18, and the end that bearing pin 3 exposes from junction plate 52 is provided with a cottor pin 6 equally.
When loader is static, fixed bar 4 is by bearing pin 3 and cottor pin 6 locking front frame 1 and rear vehicle frame 7, and fixed bar 4 is connected with lock 3 18, and frame system and frame can not be rotated; When the loader operation, extract bearing pin 4 and the cottor pin 6 of rear vehicle frame 7 one sides, fixed bar 4 is turn to lock one 16 places of front frame 1, be loaded on bearing pin 3 and cottor pin 6, locking fixed bar 4.This bicycle frame lock fixed structure need to repeat to plug bearing pin 3, and fixed bar 4 complex process.
Separately, as shown in Figure 2, lock 2 17 is two monolock seats formations that keep at a certain distance away to front frame 1 structure, and interval is because of the little difficult welding of spacing.Fixed bar 4 structures are as shown in Fig. 4-5, and between two junction plates 42 of connecting rod 41 1 ends, because spacing is too little, welding is difficult.So bicycle frame lock fixed structure complexity, welding procedure is loaded down with trivial details, and the welding operation difficulty.
Summary of the invention
To be solved by this invention is existing wheel loader bicycle frame lock fixed structure complexity, 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 invention provides a kind of wheel loader bicycle frame lock fixed structure, the fixed end of fixed bar is connected with front frame, it is characterized in that, and 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 on 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, an end of described bearing pin is larger end, and the other end is than small end, and larger end is positioned at the outside of front frame, than 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, fixed bar one end inserts in the front frame bearing pin, has draw-in groove on bearing pin, thereby packs fixedly this end of fixed bar of back-up ring on draw-in groove into, after the fixed bar movable end inserts under vehicle frame in hinged plate hole, and cottor pin is penetrated in the fixed bar hole, thereby limit the fixed bar activity, prevent that vehicle frame from rotating; When the loader operation, extract cottor pin, rotate fixed bar to front frame fixed head place, the fixed bar projective structure to be inserted in the fixed head perforate, cottor pin is inserted in the pin-and-hole of fixed bar projective structure, thus the locking fixed bar.
The invention has the advantages that: simple in structure, technique, easy to operate, low cost of manufacture.

The specific embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
Embodiment
As shown in Fig. 8-12, be the structural representation of a kind of wheel loader bicycle frame lock fixed structure provided by the invention, an 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 on front frame 1 for the fixing fixed head 8 of fixed bar 4 movable ends 9, 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 on 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 than small end, will insert successively the fixed end of front frame 1, fixed bar 4 than small end, than 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 on 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, insert 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 the 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), complete through the 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.
