Description
Technical field
The present invention relates to electrical drive control system technical field, more specifically to a kind of special double-hung of H profile steel reconditioning
The synchronisation control means of driving.
Background technology
For H profile steel production line, in process of production, can produce often for various reasons a certain amount of surface need from
The H profile steel finished product of line reconditioning, therefore, H profile steel production line is generally imperial across configuring the special double-hung of 1~2 H profile steel reconditioning in finished product
Gantry crane.This double-hung straddle truck generally main two structures by cart and on cart main beam guide track are identical
Electric block composition.The special double-hung straddle truck structural representation of conventional H profile steel reconditioning is as shown below.For this normal
The special double-hung straddle truck of H profile steel reconditioning, because two hoists do not have automatic flat-adjustable function in lifting process, in reality
In use, if the lifting loads of two hoists or itself band-type brake elasticity are inconsistent, in long range lifting process, two cucurbits
Hanging will occur asynchronous or serious asynchronous, and the shaped steel lifting clamping jaw for being thus easily caused hoist slides.Therefore, for cucurbit
The long range lifting hung, shaped steel reconditioning work is typically only capable to complete using multiple short distance lifting, that is, lifts after certain altitude,
Operative employee must be further continued for lifting one by the nonsynchronous hoist height of unilateral amendment manually after two hoists are highly consistent
Fixed height, required adjustable height is finally reached by this multiple lifting and Levelling operation.It follows that for this conventional
The special double-hung straddle truck of H profile steel reconditioning, because during lifting there is the asynchronous problem of lifting in two electric blocks, therefore
This, not only service efficiency is low for the straddle truck, but also there is lifting safety problem.
