Description
Technical field
The utility model relates to a kind of masts type offshore wind farm erecting crane cable-pulling chain device.
Background technology
At present; The ad hoc structure of derrick crane has determined the form of the last electrical transmission of hoisting crane power supply, because its mast pedestal external diameter is bigger, external diameter reaches 5-7 rice; As adopt center slip ring mode to power on, also can not find the manufacturer of the so large diameter center of production slip ring at present.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency, a kind of simple in structure, with low cost, easy for installation, safe and reliable masts type offshore wind farm erecting crane revolution transmission cable drag chain device to be provided.
The purpose of the utility model realizes through following technical scheme: a kind of masts type offshore wind farm erecting crane cable-pulling chain device; Comprise the fixing drag chain inner ring carriage of circular ring type and the rotatable drag chain outer ring carriage of circular ring type; Drag chain inner ring carriage places on the inward flange of drag chain outer ring carriage; Drag chain inner ring carriage is provided with inner ring drag chain fixed end; Drag chain outer ring carriage is provided with outer ring drag chain fixed end, is provided with cable-pulling chain between inner ring drag chain fixed end and the outer ring drag chain fixed end, and the length of cable-pulling chain is more than or equal to the diameter of drag chain inner ring carriage.
The utility model compared with prior art has the following advantages: simple in structure, with low cost, easy for installation, safe and reliable, the life-span is longer.
Description of drawings:
Structural representation when Fig. 1 turns round-180 ° for the utility model structure;
Fig. 2 is the structural representation of 180 ° of the utility model structure revolutions;
Label among the figure: 1-drag chain inner ring carriage, 2-drag chain outer ring carriage, 3-inner ring drag chain fixed end, 4-outer ring drag chain fixed end, 5-cable-pulling chain, 6-mast pedestal.
The specific embodiment:
In order to deepen understanding to the utility model, will combine embodiment and accompanying drawing that the utility model is done further to detail below, this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of embodiment of the utility model masts type offshore wind farm erecting crane cable-pulling chain device like Fig. 1 and Fig. 2; Comprise the fixing drag chain inner ring carriage 1 of circular ring type and the rotatable drag chain outer ring carriage 2 of circular ring type; Drag chain inner ring carriage 1 places on the inward flange of drag chain outer ring carriage 2; Drag chain inner ring carriage 1 is provided with inner ring drag chain fixed end 3; Drag chain outer ring carriage 2 is provided with outer ring drag chain fixed end 4, is provided with cable-pulling chain 5 between inner ring drag chain fixed end 3 and the outer ring drag chain fixed end 4, and the length of cable-pulling chain 5 is more than or equal to the diameter of drag chain inner ring carriage 1.
The purpose of the utility model is the form for the last electrical transmission that solves masts type offshore wind farm erecting crane power supply, and the utility model mainly is made up of inner ring drag chain fixed end, drag chain inner ring carriage, outer ring drag chain fixed end, cable-pulling chain, drag chain outer ring carriage etc.Drag chain inner ring carriage is fixedly mounted on the mast pedestal 6 of hoisting crane, and inner ring drag chain fixed end is fixedly mounted on the drag chain inner ring carriage, and cable gets into drag chain from drag chain inner ring fixed end; Drag chain outer ring carriage is installed in the gyro-rotor position of the swing type mechanism of hoisting crane, and outer ring drag chain fixed end is fixedly mounted on the carriage of drag chain outer ring, cable from the drag chain outer ring fixed end draw, thereby cause control housing to cable.Cable-pulling chain can be realized 360 ° (± 180 °) revolution, thus the power supply when guaranteeing hoisting crane work revolution and the transmission of control signal.The utlity model has advantage simple in structure, with low cost, easy for installation, safe and reliable, that the life-span is longer.
