Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing:
Referring to attached drawing 1, Fig. 2, a kind of embodiment of concrete mixer telescopic outrigger of the utility model, including fixed supporting leg 1,
Level-one telescopic outrigger 3 and landing supporting leg 4, increase a second level telescopic outrigger 2 between fixed supporting leg 1 and level-one telescopic outrigger 3,
Second level telescopic outrigger 2 inserts into the inner chamber from one end of fixed supporting leg 1, and along linear slide.Level-one telescopic outrigger 3 is stretched from second level
One end of contracting supporting leg 2 inserts into the inner chamber, and along linear slide.Bi-directional expansion oil is fixed in the inner cavity of second level telescopic outrigger 2
A pin shaft bracket A 7 is arranged in cylinder 5 inside the fixing end of fixed supporting leg 1, in level-one telescopic outrigger 3 close to the one of landing supporting leg 4
End is internal to be arranged a pin shaft bracket B 9.The top pin shaft A 6 of the cylinder rod A 5.1 of 5 one end of bi-directional expansion oil cylinder is fixed on
On pin shaft bracket A 7；The top pin shaft B 8 of the cylinder rod B 5.2 of 5 other end of bi-directional expansion oil cylinder is fixed on pin shaft bracket
On B 9.
Specifically: the stroke length for the cylinder rod A 5.1 that above-mentioned bi-directional expansion oil cylinder 5 is connect with fixed supporting leg 1 is less than
The cavity length of fixed supporting leg 1.The stroke length for the cylinder rod B 5.2 that bi-directional expansion oil cylinder 5 is connect with level-one telescopic outrigger 3 is small
In the length of level-one telescopic outrigger 3.It can ensure that the firm stable of connecting portion when two-stage supporting leg stretches out in this way.
In order to guarantee that two-stage landing leg stretching is smooth, the bottom of chamber in the port that fixed supporting leg 1 is used to protrude into second level telescopic outrigger 2
A pair of of support roller A 11 is arranged in portion two sides, and a pair of of pulley A 10 is arranged in 1 other end inner cavity top two sides of fixed supporting leg.It is stretched in second level
