By the arrangement, the initial value of the value can be judged, the initial value obtaining mode is very simple, and the effective operation of the subsequent alternate jacking climbing frame part A is facilitated.
Specifically, climbing frame part a has a plurality of guide rails 11, and jacking part B corresponds and is equipped with multiunit jacking
Specifically, the climbing frame part a has a plurality of guide rails 11, the jacking part B is correspondingly provided with a plurality of sets of jacking
That is to say, when jacking is needed initially, each guide rail 11 is leveled first, and specific parameters obtained by each jacking device 11 after leveling are more accurate, so that the problem that errors are gradually accumulated after jacking is carried out after initial non-leveling is avoided.
Referring now to one embodiment, a process for climbing a rack is provided.

When the horizontal height deviation of the wall-attached
At the beginning of jacking, the lower stay 22-d is in a fully retracted state, the upper stay 22-u is in an extended state for about half a stroke, and the displacement value of each stay 22 is recorded.
The jacking process is as follows:
1) the piston rod of the lower stay 22-d is controlled to extend so that the lower stay hooks hook the
2) And controlling the piston rod of the upper stay bar 22-u to extend, so that the upper stay hook hooks the ladder stop 12 closest to the upper stay hook on the guide rail 11, and detecting the working pressure of the upper stay bar 22-u during extension. When the operating pressure of the upper stay 22-u is equal to the recorded operating pressure of the lower stay 22-d, the guide rail 11 is pressed against the upper stay 22-u, and the operation of the upper stay 22-u is stopped. The stroke and working pressure of the upper stay 22-u are automatically recorded, and the retracting action of the lower stay 22-d is automatically controlled until the lower stay is completely retracted.
3) And controlling the piston rod of the lower stay bar 22-d to extend out, so that the lower stay hook hooks the ladder stop 12 closest to the lower stay hook on the guide rail 11, and detecting the working pressure of the lower stay bar 22-d during extension. When the working pressure of the lower stay 22-d corresponds to the recorded working pressure of the upper stay 22-u, the guide rail 11 is held by the lower stay 22-d. And continuously extending the lower stay bar 22-d to complete a preset effective stroke, and stopping the action of the lower stay bar 22-d. The stroke and working pressure of the lower stay 22-d are automatically recorded, and the retracting action of the upper stay 22-u is automatically controlled until the upper stay is completely retracted.
4) And controlling the piston rod of the upper stay bar 22-u to extend, so that the upper stay hook hooks the ladder stop 12 closest to the upper stay hook on the guide rail 11, and detecting the working pressure of the upper stay bar 22-u during extension. When the operating pressure of the upper stay 22-u is comparable to the recorded operating pressure of the lower stay 22-d, the guide rail 11 is held against the upper stay 22-u. And continuously extending the upper stay bar 22-u to complete a preset effective stroke, and stopping the action of the upper stay bar 22-u. The stroke and working pressure of the upper stay 22-u are automatically recorded, and the retracting action of the lower stay 22-d is automatically controlled until the lower stay is completely retracted.
And then repeating the step 3) and the step 4) until the climbing frame part A reaches the required jacking height.
After climbing, the height difference between the top elevation of each guide rail 11 and the elevation required to be reached is measured by an instrument, the adjustment amount is input into a control system and then is adjusted in height through the extension and contraction of the
