Abstract
The utility model provides a kind of engineering gauntry crane jack up unit, comprise winch, middle leading sheave seat, two winchs share steel cable, steel rope enters between opposite side running block and fixed pulley group from the middle leading sheave of left side winch, be wound around through 8 times, the fixed end being finally wound into right side winch is fixed, and forms single suspension centre structure.This patent vibrational power flow, lifting mechanism of gantry crane 4 lifting, 3 balances, guarantee each suspender stress equalization, avoid precast beam simultaneously and turned round in lifting process.Add the safety factor of precast beam in lifting process, avoid the damage of precast beam.
Description
Technical field
The utility model relates to lifting device of crane field, particularly a kind of engineering gauntry crane jack up unit.
Background technology
At present, gauntry crane when employing two crane liftings or a hoisting crane two dollies lift is, general lifting mechanism is two independent covers or four cover fixed pulleys, the lifting mechanism of running block composition, such lifting mechanism is all that independent point hoists decline, due to lifting motor error in the mill, the difference of every platform motor speed can be caused unavoidably, add the centre-of gravity shift of precast beam itself, the deflection of precast beam in lifting process can be caused thus, become the potential safety hazard of precast beam lifting, and when placing precast beam, the damage of precast beam can be caused.
Therefore, the utility model develops on the basis mainly solving more than currently available technology existence deficiency.
Summary of the invention
The object of utility model solves above technical matters, the engineering gauntry crane jack up unit of the damage propose a kind ofly to improve safety factor especially, avoiding precast beam.
Based on above-mentioned purpose, the technical matters that the utility model solves realizes by the following technical solutions:
A kind of engineering gauntry crane jack up unit, comprise winch, middle leading sheave seat, two winchs share steel cable, steel rope enters between opposite side running block and fixed pulley group from the middle leading sheave of left side winch, be wound around through 8 times, the fixed end being finally wound into right side winch is fixed, and forms single suspension centre structure.
Further, also comprise two each personal steel cables of winch, by middle leading sheave, simultaneously enter between running block and fixed pulley group from equalizer pulley, through the winding of 8 times, be finally anchored on fixed end, form two suspension centre structure.
The beneficial effects of the utility model are, this patent vibrational power flow, and lifting mechanism of gantry crane 4 lifting, 3 balances, guarantee each suspender stress equalization, avoid precast beam simultaneously and turned round in lifting process.Add the safety factor of precast beam in lifting process, avoid the damage of precast beam.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model list suspension centre;
Fig. 2 is the structural representation of the two suspension centre of the utility model;
Detailed description of the invention
Below by way of Figure of description, further set forth the utility model;
According to Fig. 1, a kind of engineering gauntry crane jack up unit, comprise elevator 1, middle leading sheave seat 8, two winchs 1 share steel cable 3, steel rope 3 enters between opposite side running block 5 and fixed pulley group 4 from the middle leading sheave 6 of left side winch 1, be wound around through 8 times, the fixed end 7 being finally wound into right side winch 1 is fixed, and forms single suspension centre structure.
According to Fig. 2, also comprise two each personal steel cables 7 of winch 1, by middle leading sheave 8, enter between running block 5 and fixed pulley group 4 from equalizer pulley 2 simultaneously, through the winding of 8 times, be finally anchored on fixed end 7, form two suspension centre structure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
