Described stretching, extension pulley described in the utility model and shrink pulley and be all two, symmetry be installed in the both sides of corresponding casing.
Advantage and good effect that the utility model is compared with prior art had are: structure lightly, does not need to increase power, steady, simple, easy to maintenance, the low cost of manufacture of processing of motion again.
To and contrast accompanying drawing by embodiment below is described specifically the utility model:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the assembly structure figure that shrinks pulley A (2) among Fig. 1.
Fig. 3 is the assembly structure figure that shrinks pulley B (5) among Fig. 1.
Fig. 4 is the assembly structure figure that stretches pulley A, B (11,8) among Fig. 1.
As shown in the figure, present embodiment is the level Four telescopic arm structure, by first segment arm 1, the second joint arm 4, the 3rd joint arm 6, the 4th joint arm 9, stretch pulley A11, stretch pulley B8, shrink pulley A2, shrink pulley B5, stretch steel cable A12, stretch steel cable B10, shrink steel cable A3, shrink steel cable B7, piston rod 15, telescopic oil cylinder 16, piston rod set pin 14, cylinder body set pin 13 form.Piston rod 15 is fixed on the rear end of first segment arm 1 by piston rod set pin 14, and telescopic oil cylinder 16 is fixed on the rear end of the second joint arm 4 by cylinder body set pin 13, and the piston rod kink is in telescopic oil cylinder.
The stretching, extension pulley A11 of the 3rd joint arm is fixed on the front end box inside (left and right sides together) of the second joint arm 4, the contraction pulley A2 of the 3rd joint arm is fixed on the rear end box inside (left and right sides together) of the second joint arm 4, the stretching, extension steel cable A12 pile warp of the 3rd joint arm stretches the rear end box inside that pulley A11 one end is fixed by bolts to first segment arm 1, the other end is fixed on the 3rd joint arm 6 rear end box insides (left and right sides together), the contraction steel cable A3 pile warp of the 3rd joint arm is shunk pulley A2, one end is fixed by bolts to the front end box inside of first segment arm 1, and the other end is fixed by bolts to the rear end box inside (left and right sides together) of the 3rd joint arm 6.
The stretching, extension pulley B8 of the 4th joint arm 9 is fixed on the front end box inside (left and right sides together) of the 3rd joint arm 6, the contraction pulley B5 of the 4th joint arm 9 is fixed on the rear end box inside (left and right sides together) of the 3rd joint arm 6, the stretching, extension steel cable B10 pile warp of the 4th joint arm stretches the rear end box inside that pulley B8 one end is fixed by bolts to the second joint arm 4, the other end is fixed on the rear end box inside (left and right sides together) of the 4th joint arm 9, the contraction steel cable B7 pile warp of the 4th joint arm is shunk the front end box inside that pulley B5 one end is fixed by bolts to the second joint arm 4, and the other end is fixed by bolts to the rear end box inside (left and right sides together) of the 4th joint arm 9.
Principle of work of the present utility model is: during stretching, extension, active force telescopic oil cylinder 16 travels forward, piston rod 15 is motionless, the motion of telescopic oil cylinder 16 promotes the second joint arm 4 s stroke that travels forward, owing to stretch the front end that pulley A11 is fixed on the second joint arm 4, therefore stretch pulley A11 and the second joint arm, 4 synchronous extension, at this moment, it is fixed on first segment arm 1 rear end to this section steel cable that stretches pulley A11 center and elongates the s stroke to stretch steel cable 12, receive short s stroke and be fixed on the 3rd joint arm 6 rear ends to this section steel cable that stretches pulley A11 center, force the 3rd joint arm 6 and the second joint arm, 4 synchronous extension s strokes.For the level Four telescopic arm structure, the motion of the 4th joint arm 9 is carried out synchronously with second, third joint arm, its active force is the 3rd joint arm 6, owing to stretch the front end that pulley B8 is fixed on the 3rd joint arm 6, therefore stretch pulley B8 and the 3rd joint arm 6 synchronous extension, at this moment, it is fixed on the second joint arm, 4 rear ends to this section steel cable elongation s stroke that stretches pulley B8 center to stretch steel cable B10, receive short s stroke and be fixed on the 4th joint arm 9 rear ends to this section steel cable that stretches pulley B8 center, force the 4th joint arm 9 and the 3rd joint arm 6 synchronous extension s strokes.
During contraction, the active force Shen oil cylinder 16 that contracts moves backward, piston rod 15 is motionless, the motion of telescopic oil cylinder 16 drives the second joint arm 4 s stroke that moves backward, owing to shrink the rear end that pulley A2 is fixed on the second joint arm 4, therefore shrink pulley A2 and the second joint arm, 4 synchronous, at this moment, it is fixed on first segment arm 1 front end to this section steel cable elongation s stroke that shrinks pulley A2 center to shrink steel cable A3, receive short travel and be fixed on the 3rd joint arm 6 rear ends to this section steel cable that shrinks pulley A2 center, force the 3rd joint arm 6 and the second joint arm, 4 synchronous s strokes.Equally, for the 4th joint arm 9 its active forces are the 3rd joint arms 6, owing to shrink the rear end that pulley B5 is fixed on the 3rd joint arm 6, therefore shrink pulley B5 and the 3rd joint arm 6 synchronous, at this moment, it is fixed on the second joint arm, 4 front ends to this section steel cable elongation s stroke that shrinks pulley B5 center to shrink steel cable B7, receives short s stroke and be fixed on the 4th joint arm 9 rear ends to this section steel cable that shrinks pulley B5 center, forces the 4th joint arm 9 and the 3rd to save arm 6 synchronous s strokes.
