The utility model is realized through following technical scheme for realizing above-mentioned purpose: the big arm hook of a kind of adjustable spring reset comprises hook rocking bar, connecting screw rod, hook connecting rod, big arm hook, spring and rack-mounted limiting plate and axle; Frame is provided with slotted eye, is provided with in the slotted eye to top bar and get out of a predicament or an embarrassing situation; The hook rocking bar is a hook-type, and the hook-type front end of hook rocking bar passes from slotted eye, and the center is movably articulated on the frame, and its tail end flexibly connects the connecting screw rod upper end; The connecting screw rod lower end flexibly connects the hook small end, and hook connecting rod bottom flexibly connects big arm hook upper end; Big arm hook is between frame and limiting plate, and its top is fixed on the axle; Spring one end coupling hook connecting rod lower end, the other end connects limiting plate.
Further, connecting screw rod comprises screw rod contiguous block and contiguous block II, and the thread rotary orientation at screw rod two ends is opposite, and contiguous block and contiguous block II are installed in the screw rod two ends through nut I, nut II respectively.
Further, hook rocking bar middle part is movably articulated on the frame through screw bolt and nut.
Further, hook rocking bar tail end flexibly connects the connecting screw rod upper end through the pin I.
Further, hook connecting rod bottom flexibly connects big arm hook upper end through the pin II.
Further, arm hook top is installed on the axle through elastic cylindrical pin greatly.
The beneficial effect of the utility model is: promotes at the big arm of paver on the basis of auto-lock function of hydraulic system, increased locking device, thereby constituted the double locking function of big arm with frame for movement, and easy to operate, reliable in structure.

Among the figure: 1, frame, 2, the hook rocking bar, 3, slotted eye, 5, the pin I, 6, connecting screw rod; 7, hook connecting rod, 8, the pin II, 9, axle, 10, elastic cylindrical pin, 11, spring; 12, limiting plate, 13, big arm hook, 14, right big arm, 15, the contiguous block I; 16, screw rod, 17, the contiguous block II, 18, the nut I, 19, the nut II.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model comprises hook rocking bar 2, connecting screw rod 6, hook connecting rod 7, big arm hook 13, spring 11 and is installed in limiting plate 12 and the axle 9 on the frame 1; Frame 1 is provided with slotted eye 3, is provided with in the slotted eye 3 and tops bar and get out of a predicament or an embarrassing situation; Hook rocking bar 2 is a hook-type, and the hook-type front end of hook rocking bar 2 passes from slotted eye 3, and the center is movably articulated on the frame 1, and its tail end flexibly connects connecting screw rod 6 upper ends; Connecting screw rod 6 lower ends flexibly connect hook connecting rod 7 upper ends, and hook connecting rod 7 bottoms flexibly connect big arm and link up with 13 upper ends; Big arm hook 13 is between frame 1 and limiting plate 12, and its top is fixed on the axle 9; Spring 11 1 end coupling hook connecting rods 7 lower ends, the other end connects limiting plate 12.
Wherein, connecting screw rod 6 comprises screw rod 16 contiguous blocks 15 and contiguous block II 17, and the thread rotary orientation at screw rod 16 two ends is opposite, and contiguous block 15 is installed in screw rod 16 two ends through nut I 18, nut II 19 respectively with contiguous block II 17.
Wherein, hook rocking bar 2 middle parts are movably articulated on the frame 1 through screw bolt and nut.
Wherein, hook rocking bar 2 tail ends flexibly connect connecting screw rod 6 upper ends through pin I 5.
Wherein, hook connecting rod 7 bottoms flexibly connect big arm through pin II 8 and link up with 13 upper ends.
Wherein, big arm is linked up with 13 tops and is installed on the axle 9 through elastic cylindrical pin 10.
During enforcement, as shown in Figure 1, axle 9 is welded on the frame 1 with limiting plate 12, and hook rocking bar 2, connecting screw rod 6, hook connecting rod 7, big arm hook 13 all can be around its tie point rotations each other.
As shown in Figure 4, screw rod 16 the right and left thread rotary orientations are opposite, come the distance between the contiguous block I 15 and contiguous block II 17 on the adjusting screw(rod) 16 through adjusting nut I 18, nut II 19, thus the position when controlling big arm hook 13 work.
As shown in Figure 2, adjusting screw(rod) 16 impels the two-stage step of hook rocking bar 2 in frame 1 slotted eye to move up and down.When hook rocking bar 2 is positioned at when getting out of a predicament or an embarrassing situation, i.e. the hook of solid line shown in Fig. 2 rocking bar 2, big arm hook 13 be promptly at the solid line position shown in Fig. 1, and this moment, big arm was linked up with 13 inoperative.When hook rocking bar 2 is positioned at when topping bar, dotted line hook rocking bar 2 as shown in Figure 2, big arm hook 13 are promptly at dotted line position as shown in Figure 1, and this moment, big arm hook 13 just in time tangled big arm 14.
