An example of a preferred application of the three-way stabilizer for preventing tilting and shaking during lifting and transferring is as follows: referring to fig. 1, the batch lifting system for the cultivation boxes comprises the three-way stabilizing device capable of preventing inclination and shaking in lifting and transferring, a cultivation pond 100 and a connecting rod 200, wherein the supporting seat 10 of the three-way stabilizing device is positioned on two sides of the cultivation pond, the frame 30, the track 20, the lifting mechanism 40 and the hanging frame 50 are positioned above the cultivation pond 100, grooves 101 (which can be V-shaped grooves) for accommodating two ends of the connecting rod are concavely formed in the top end faces of two opposite side pond walls of the cultivation pond 100, and the connecting rod 200 can be connected with the hanging pieces 51 on the hanging frame 50.

hanging guide rails

61 and 62, the hanging frame 50, the connecting rod 200 and the cultivation boxes 300 always vertically ascend along the guiding of the hanging guide rail group 60, and the situations of overturning, tilting, shaking and the like do not occur in the middle.

The principle of the stabilizing device for preventing overturning, tilting, shaking and the like is as follows (taking two C-shaped guide rails for each suspension guide rail assembly 60 and two rollers for each roller group 72 as an example):

when the gravity centers of the lifting and transferring cultivation box group and the hanging frame are unbalanced, or the device performs acceleration and deceleration movements such as start-stop and the like, the hanging frame can be subjected to moment of side tilting, overturning or deflection. The rollers in the stabilizer will now press against the suspension rail, whereby a pressing force is obtained to balance the roll, roll or yaw moment. The balance analysis of the roll moment is shown in fig. 6 irrespective of the roller friction effect. Let G1 be the pulling force of the cultivation box 300 on the hanger 50, F1 be the pulling force of the electric hoist 41 on the hanger 50, and L1 be the distance of G1 from the action point O of F1. Under the action of the roll moment generated by G1 and F1, the 4 rollers of the hanger 50 located in the inner suspension rail 61 at the left and right ends thereof will press the raceway surface of the inner suspension rail, generating pressing forces Fn1, fn2, fn3, fn4 acting on the rollers to balance the roll moment generated by G1 and F1. The pressing forces acting on the hanger rail group 60 corresponding to Fn1, fn2, fn3, fn4 tend to deflect the inner hanger rail 61 around the fixed end. Considering the elastic deformation of the hanger rail group 60, the deflection around the fixed end under the pressing force increases the pressing forces Fn1 and Fn3 near the fixed end of the hanger rail group 60, and decreases the pressing forces Fn2 and Fn4 far from the fixed end of the hanger rail group 60. The cantilever arrangement results in a small deflection angle of the set of suspension rails 60, which results in significantly greater Fn1 and Fn3 than Fn2 and Fn4, so that the set of suspension rails 60 does not deflect significantly relative to the fixed end while balancing roll moment. Therefore, the capacity of the inboard suspension rail 61 to balance moment in the direction perpendicular to the inboard suspension rail 61 is not reduced with respect to the rails fixed at both ends. The rollers which are required to cooperate with the inner suspension rail 61 are symmetrically arranged at the two ends of the vertical rod 71 at intervals in pairs, so that the suspension rail does not deflect significantly relative to the fixed end while balancing the roll moment, and the larger the distance between the two rollers along the vertical rod is, the stronger the capability of balancing the roll moment is. Assuming that the moment arms of Fn1, fn2, fn3 and Fn4 to the center O point of the hanger are all H, the moment balance equation of the hanger is G1×L1= (Fn1+Fn2+Fn3+Fn4) ×H.

Fig. 7 is a diagram showing a moment balance analysis of the hanger 50 when the hanger 50 receives the turning moment M1. At this time, the 4 rollers of the hanger 50 positioned at the left and right ends in the outer suspension rail 62 press the raceway surface of the outer suspension rail 62, and the pressing forces Fn5, fn6, fn7, fn8 acting on the rollers are generated to balance the turning torque M1. The pressing forces acting on the set of hanger rails 60 corresponding to Fn5, fn6, fn7, fn8 tend to deflect the outer hanger rail 62 about the fixed end. Considering the elastic deformation of the hanger rail group 60, the deflection around the fixed end under the pressing force increases the pressing forces Fn5 and Fn6 near the fixed end of the hanger rail group 60, and decreases the pressing forces Fn7 and Fn8 far from the fixed end. The cantilever arrangement is such that a small deflection angle of the set of hanger rails 60 will result in Fn5 and Fn6 being significantly greater than Fn7 and Fn8, so that the outboard cantilever rails 62 will not deflect significantly from the fixed ends themselves while balancing the overturning moment. The ability of the outboard hanger rail 62 to balance the moment in the vertical rail direction is not reduced by fixing the rails at opposite ends. The roller sets which are required to be matched with the outer suspension guide rail 62 are symmetrically arranged at the two ends of the vertical rod at intervals in pairs, so that the suspension guide rail set 60 can not obviously deflect relative to the fixed end while balancing the overturning moment, and the larger the distance between the two pulley blocks along the vertical rod is, the stronger the capability of balancing the overturning moment is. Assuming that the moment arms of Fn5, fn6, fn7, fn8 to the hanger center O point are all L2, the moment balance equation of the hanger 50 is m1= (fn5+fn6+fn7+fn8) ×l2.

Fig. 8 and 9 are moment balance analysis diagrams of the hanger 50 when the hanger 50 receives the yaw moment M2. At this time, the 4 rollers located in the outer suspension rail 62 at the left and right ends of the hanger 50 press the raceway surface of the outer suspension rail 62, and generate pressing forces Fn9, fn10, fn11, fn12 acting on the rollers to balance the yaw moment M2. The pressing forces acting on the set of suspension rails 60 corresponding to Fn9, fn10, fn11, fn12 tend to deflect the outer suspension rail 62 about the fixed end. The lower ends of the outer side suspension rail 62 and the inner side suspension rail 61 are fixedly connected through an L-shaped connecting plate 63, so that the deflection moment generated by the extrusion force on the rails is jointly resisted by the inner side and the outer side suspension rails 61 and 62, thereby reducing the deflection angle of the suspension rail group 60 and improving the balancing capability of the deflection moment M2. Assuming that the moment arms of Fn9, fn10, fn11, fn12 to the hanger center O point are all L3, the moment balance equation of the hanger 50 is m2= (fn9+fn10+fn11+fn12) ×l3.

To sum up, this stabilising arrangement can automatic balance side to incline, upset and yaw moment, prevents to lift slope and rocking in the transportation process, realizes three-dimensional stability, has the translation degree of freedom that vertical lift and level march simultaneously, finally realizes steady lifting by crane and march.

The utility model specifically arranges the roller assembly 70 and the suspension guide rail group 60 so that the suspension guide rail group 60 does not deflect relatively to the suspension fixing end while balancing the multi-directional moment. The opening directions of the C-shaped guide rails in the suspension guide rail group 60 are required to be rotationally arranged at intervals of 90 degrees, so that the torques in a plurality of orthogonal directions can be balanced, and a plurality of rollers sliding along the same C-shaped guide rail are required to be symmetrically arranged in pairs at certain intervals, so that the suspension guide rail group 60 can not obviously deflect relative to the suspension fixed end while balancing the corresponding torques.

The foregoing description is only illustrative of the preferred embodiments of the present utility model, and therefore should not be taken as limiting the scope of the utility model, for all changes and modifications that come within the meaning and range of equivalency of the claims and specification are therefore intended to be embraced therein.
