Embodiment Construction

[0027] See figure 1 , A process method for hoisting extra-large equipment by rotating balance method is:

[0028] In the workshop near the hoisting installation position, the frame assembly platform 7 and the slide rail 8 of the super large equipment are positioned and fixed on the foundation embedded parts. The slide rail 8 is made horizontal under the support of the track leg 9 and moves horizontally. The device 3 is located on the slide rail 8.

[0029] Use the workshop crane 6 to hoist the parts of the extra-large rack to the assembly platform 7, adjust and assemble the rack 1 into a whole in a horizontal state, see Figure 5 .

[0030] Then clamp the frame turning device 2 and frame 1, see Figure 5 , Figure 6 , Figure 7 . The frame turning device 2 includes a frame turning frame 21, a rotation pin 4, a positioning pin 22, and a connecting bolt 23. The frame turning frame 21 includes left and right end beams 24, a rear beam 25, a front beam 26, and a stop beam 27. The fron...

Abstract

The invention is about the process to hang the large device by the rotary balance method. It to fix the large device frame off-center to make a fulcrum to balance the frame gravitation and the hoister lifting force. The load of the hoister is much less than the gravitation of the frame, so the hoister can lift large device in the present workshop space. So it can decrease the working time and the cost.

Description

(1) Technical field [0001] The invention relates to a hoisting process for extra-large equipment, in particular to a process method for hoisting an extra-large equipment using the principle of leverage. (2) Background technology [0002] The general requirements for the hoisting of extra-large equipment are: (1) Workshop cranes or crawler or truck cranes with hoisting capacity; (2) Sufficient equipment placement sites; (3) Sufficient height and height for hoisting Plane space. However, in actual operation, for the hoisting of extra-large equipment, ordinary workshops cannot meet the above three conditions. For example, for the hoisting of the extra-large rolling mill stand (length 14.1 m, width 5.4 m, weight 450 tons) of a certain unit of wide and heavy plate factory, conventional hoisting technology is adopted, considering that the maximum lifting weight of the crane in the workshop is only 100 tons, and The equipment underground and the surrounding area are underground oil depo...
