[0051] In summary, the longitudinal moving trolley 1 is carried by the bridge track beam 2 to move along the longitudinal direction. When the lateral moving trolley 4 is carried by the lifting mechanism 3 to move along the lateral direction, the extension cylinder 11.2 of the lower clutch mechanism 11 is extended to push the outer end of the swing arm 11.1 downward, so that the swing arm 11.1 swings around the pivot of the lug plate 11.1.3 as the center, that is, the inner end of the swing arm 11.1 pulls the prismatic sleeve 11.6 and the friction ring 11.7 upward through the short shaft 11.5 and the sleeve 11.4, the prismatic sleeve 11.6 is sleeved upward relative to the prismatic 7.1 to a certain distance, until the friction surface of the friction ring 11.7 is attached to the friction surface of the friction ring 2 10.4. At this time, the power of the motor 10.1 is transmitted to the power input shaft of the T-shaped commutator 7 through the prismatic 10.2, the vertical shaft 10.3, the friction ring 2 10.4, the friction ring 11.7, the prismatic sleeve 11.6 and the prismatic 7.2, and the power output shaft of the T-shaped commutator 7 is transmitted to the linkage 4.6 through the prismatic sleeve 7.2 and the shaft connecting piece 6, so that the linkage 4.6 rotates, and the linkage 4.6 drives the walking wheel 4.5 to roll through the meshing relationship between the gear ring 1 4.5.4 and the gear ring 2 4.6.3, so as to realize the walking of the lateral moving trolley 4. In addition, the remaining walking wheels 4.5 play a supporting and guiding role, and the remaining pairs of walking wheels 4.5 are linked through corresponding linkages 4.6 and shaft connecting pieces 6 respectively to ensure that the walking wheels 4.5 on the front and back sides walk synchronously, so as to realize the stable and straight walking of the lateral moving trolley.

[0052] When the hoisted heavy object needs to be adjusted, the piston rod of the lower extension cylinder 11.2 is retracted first, so that the friction ring 11.7 falls until the friction ring 11.7 and the friction ring 2 10.4 are separated. Then the outer end of the swing arm 11.1 is pulled upward by the extension cylinder 11.2 of the upper clutch mechanism 11, so that the swing arm 11.1 swings around the pivot of the lug plate 11.1.3 as the center, that is, the inner end of the swing arm 11.1 pushes the prismatic sleeve 11.6 and the friction ring 11.7 downward through the short shaft 11.5 and the sleeve 11.4, the prismatic sleeve 11.6 is sleeved downward relative to the prismatic 3 10.2 to a certain distance, until the friction surface of the friction ring 11.7 is attached to the friction surface of the friction ring 1 9.4. At this time, the power of the motor 10.1 is transmitted to the gear 1 9.2 through the prismatic 3 10.2, the prismatic sleeve 11.6, the friction ring 11.7, the friction ring 1 9.4 and the hollow shaft 9.3, and the gear 1 9.2 drives the outer gear ring 5.2 to rotate through the gear 2 9.5, so as to realize the rotation of the rotating disc 5 carried by the lifting mechanism 3, so as to achieve the effect of flexible steering of the hoisted heavy object. When the piston rod of the upper extension cylinder 11.2 is extended, the power transmission between the motor 10.1 and the gear 1 9.2 is cut off.

[0053] The lifting wire rope of the lifting mechanism 3 is hung down from the rectangular cavity surrounded by the cross beam 4.4 and the side beam 4.3.
