Description
Technical field
The invention belongs to the technical field of the overweight transporting equipment of industrial production, it is related to being applied to rising in metallurgical industry production
Weight Transport Machinery.More particularly it relates to a kind of synchronisation control means of the special double-hung driving of H profile steel reconditioning.
Background technology
In the production process of H profile steel production line, for various reasons, it will produce a certain amount of surface often and need offline
The H profile steel finished product of reconditioning, for this purpose, H profile steel production line is usually in finished product across the special double-hung gantry of 1~2 H profile steel reconditioning of configuration
It hangs.
The special double-hung gantry crane structural schematic diagram of H profile steel reconditioning commonly used in the prior art is as depicted in figs. 1 and 2.This
The main body of kind double-hung gantry crane is cart, and the cart that cart is moved by girder 4, supporting beam 1, ground beam 6 and driving cart is transported
Row mechanism 5 forms.Cart be equipped be mounted on 4 guide rail of cart girder on two completely identical in structure suspension hook trolleies, every
One electric block 3 is set on suspension hook trolley.Electric block 3 is equipped with suspension hook.Electric block 3 passes through cable 7 and double-hung dragon
The control system of gantry crane connects.
For this common special double-hung gantry crane of H profile steel reconditioning, since two electric blocks are hung in lifting process
In there is no automatic flat-adjustable function, in actual use, if the lifting loads of two electric gourd hangs or itself band-type brake elasticity are not
Unanimously, then in long range lifting process, two electric gourd hangs will will appear asynchronous or serious asynchronous, thus easily lead to
The shaped steel lifting clamping jaw of hoist slides.As the above analysis, for the special double-hung gantry crane of common H profile steel reconditioning,
Due to not having automatic flat-adjustable function, it is easy to appear asynchronous problems in long range lifting process for double-hung.
For this purpose, the long range for electric gourd hang lifts, shaped steel reconditioning work is typically only capable to lift using multiple short distance
It could complete, i.e.,：After lifting certain altitude, operative employee must by the manual unilateral nonsynchronous electric gourd hang height of amendment,
It is further continued for lifting certain altitude after two electric gourd hangs are highly consistent, is finally reached by this multiple lifting and Levelling operation
To required adjustable height.
It follows that for this common special double-hung gantry crane of H profile steel reconditioning, due to two electricity during lifting
Dynamic cucurbit, which exists, lifts asynchronous problem, and therefore, not only service efficiency is low for the gantry crane, but also there is lifting safety problem.
