Detailed description of the invention
Below in conjunction with accompanying drawing, lower detailed description of the invention is described:
As shown in figs. 1-11, a kind of tong is cut and is picked up seam and integrally rescue accessory, including fourth officer double leval jib embrace grapple structure (A), permanent shearing force device (B), play seam device (C), pincers are cut to embrace and are grabbed morphological transformation device (D) and constitute.
Rescue accessory is in embrace and grabs form as shown in Figure 1, now double leval jib embrace grapple structure (A) embrace grab hydraulic cylinder (3) will embrace a handgrip grab (5) release block pincers shear blade (7), pincers shear blade (7) are damaged when grabbing in order to avoid embracing, pincers are cut and are embraced grab on morphological transformation device (D) two deformation hydraulic cylinder (11) and moved out by slide block simultaneously, expansion armful handgrip is grabbed embracing between (5) and is grabbed distance, pin to embrace and grab hydraulic cylinder (3) and deformation hydraulic cylinder (11), drive tooth bar (9) to rotate arc cutter for gear wheel (6) realization armful by the driving hydraulic cylinder (10) in Fig. 7 and grab function.
Fig. 5 show permanent shearing force device (B), accessory cut by current common pincers, mostly it is mounted to the double hydraulic cylinder of both sides, its pincers are cut process shearing force and are changed along with the variable angle of both sides hydraulic cylinder and cutter, or arrive change or descending change due to little, need the rescue work of constant shear power cannot use at some, stressing conditions as shown in figure 12, wherein F1For hydraulic cylinder power output, F2For the counter-force of fulcrum O, F3Counter-force suffered by clip, therefore:
F 1 + F 2 + F 3 = 0 F 1 · O 1 O · sin α + OO 2 · F 3 = 0 - - - ( 1 )
The counter-force of clip can be obtained:
| F 3 | = | F 1 | O 1 O OO 2 s i n α - - - ( 2 )
Namely clamping the variable angle of shearing and hydraulic cylinder and cutter and change, when angle is 90 °, pincers shearing is maximum.Pincers scissors tool is designed as arc-shaped gear colyliform by the present invention, engage by driving hydraulic cylinder (10) to connect tooth bar (9), make to drive the angle between direction and the arc gear wheel cutter (6) of hydraulic cylinder (10) power output to remain unchanged, and it is 90 °, thus shearing force is constant maximum value.
Fig. 6, Fig. 7 be pincers cut embrace grab morphological transformation device (D), two, left and right deformation hydraulic cylinder (11) controls the motion of slide block (12), deform hydraulic cylinder (11) during shearing and promote slide block (12) Guan Bi, deformation hydraulic cylinder (11) is pinned, and cuts by driving hydraulic cylinder (10) to realize pincers, plays joint function；Embracing deformation hydraulic cylinder (11) when grabbing promotes slide block (12) to open up into applicable distance, and deformation hydraulic cylinder (11) is pinned, and embraces by driving hydraulic cylinder (10) to realize and grabs operation.
Figure 11 has been seam form, now two deformation hydraulic cylinder (11) drive slide block (12) to close and pin slide block (12), embrace grab hydraulic fluid cylinder pressure (3) drive embrace a handgrip grab (5), it is embrace a handgrip to grab (5) and neither block pincers shear blade, do not stretch out outside arc gear wheel cutter (6) yet, embrace that to grab hydraulic fluid cylinder pressure (3) locked afterwards, drive hydraulic cylinder (10) to realize stitching operation by passing through.
