Chamber, oil return, by stretching bar cramp layer oil return, is stretched the one of a cylinder and stretches cylinder rod first 7.1 and stretched out, such as Fig. 5 by rod chamber；When stretching a cylinder
One when stretching cylinder rod first 7.1 and reaching bottom soon, core pull bar 7.8 opens pull-type nonreturn valve core 7.9, and hydraulic oil is worn from Shen Yigan centers
The center of core pull bar 7.8 is crossed, by pull-type nonreturn valve core 7.9, then { cylinder cylinder head 7.2 and two is stretched and is stretched cylinder due to one by conduit 7.12
Head 7.3 is to be rigidly connected, and is not relative motion, and the conduit can use steel pipe manufacturing }；Enter into and stretch two cylinder rodless cavity, stretch two
Cylinder stretches out, and the same cylinder of stretching of oil return stretches out；So stretch two cylinder to stretch out, by mechanical nonreturn valve core, just telescoping cylinder is strict in order
It is flexible；Similarly, retract opposite.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5 and Fig. 6, between the arm 2 of large arm 1 and two, between two arms 2 and three arms 3, three
Without steel wire rope between the arm 4 of arm 3 and four, the structural section drop of large arm 1, two arms 2, three arms 3 and four arms 4 is substantially reduced, also
Can be the space that five arms 5 and six arms 6 are considerably increased in the case of equal large arm section, while one stretches cylinder and two and stretches cylinder
It is rigidly connected, the oil circuit between not having hydraulic hose to connect reduces flexible pipe arrangement and leakage point, increases inner space, double
The one of telescoping cylinder 7 stretches cylinder and two and stretches cylinder by mechanical check valve, and exact sequence is stretched, and order is realized than that sensible pressure difference
It is flexible more reliable；The present apparatus can greatly reduce section drop in the design process that six joint arms are stretched, and increase telescopic oil cylinder
Space, to increase lifting performance and improve stock utilization improve a lot, while all pulleys and flexible steel wire rope
All inside arm body, that is, flexible service life of steel wire rope is increased, overall aesthetic property is improved again.
