The second ejection device 21 ejects, so that the upper end of the connector 24 enters the first notch and abuts against the bottom of the second supporting seat 22. Then, the lower part of the first cable 44 is pulled to pull up the lower end of the supporting upright 15, so that the lower end of the supporting upright 15 is separated from the second supporting seat 22, the second ejection device 21 drives the second supporting seat 22 to move, the first notch is opened, the first cable 44 is slowly released, the supporting upright 15 is put down, and the lower end of the supporting upright 15 is inserted into the connecting head 24 through the first notch. Then, the connector 24 is lifted to the upper side of the first supporting plate 3 through the lifting device 4, the unit rod 8, the connector 24 and the supporting upright 15 are fixedly connected through bolts, then the supporting upright 15 is continuously pushed up, the second supporting seat 22 is reset, the first notch is blocked, and the lower end of the unit rod 8 is propped against the second supporting seat 22 again.

When each section of unit bar 8 is assembled, the second cable 46 is connected with the loop 2402 and the first cable 44 on the newly installed connector 24, and the front and rear newly installed connectors 24 are connected by the hooking cross bar 25. Until the assembly of the support uprights 15 is completed. The ground anchor 45 at the lower end of the first cable 44 is driven into the ground for fixation, and the first cable 44 and the second cable 46 are both in a tensioned state.

When the member is lifted, the first rotary driving device 29 drives the rotating shaft 28 to rotate, so as to drive the hanging beam 30 to rotate, and the hanging beam 30 is rotated in the horizontal plane, so that the air direction of the lifted member during lifting is adjusted.

The hoisting devices 41 on the left side and the right side can be used for hoisting a component independently, and the hoisting devices 41 on the two sides can be matched with each other to hoist a component simultaneously, and the translation mechanism drives the hoisting devices 41 to move along the hoisting beam 30 so as to hoist the component to a construction site.

When the lifting devices 41 on the two sides are mutually matched and lift one component at the same time, the horizontal inclination of the lifted component can be adjusted through the length of the sling released by the lifting devices 41 on the left side and the right side, and the lifting construction requirement of the lifted component for obtaining any inclination can be met by matching the rotation of the lifting beam 30 in the horizontal plane.

Example 2: the difference between the present embodiment and embodiment 1 is that the bottom of the fixing plate 40 is fixedly provided with two lifting devices 41 disposed at intervals, front and rear. Two lifting devices 41 on the same fixing plate 40 commonly lift one member, or four lifting devices 41 on the fixing plate 40 on the left and right sides commonly lift one member. Other structures are the same as in embodiment 1.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
