Abstract
The utility model provides a turning type primary-secondary trolley for a crane. The turning type primary-secondary trolley comprises a primary trolley running on a main beam track, and is characterized in that a secondary trolley running track is formed on the primary trolley; a secondary trolley is arranged on the secondary trolley running track; the secondary trolley running track is parallel to the main beam track; a primary trolley lifting mechanism is arranged on the primary trolley; a secondary trolley lifting mechanism is arranged on the secondary trolley. The lifting mechanism is independently arranged on the secondary trolley, and the secondary trolley is arranged on the track of the primary trolley, so that the primary trolley can run on two main beams, relative movement in the horizontal direction can be realized through suspension centres of the lifting mechanism of the primary trolley and the lifting mechanism of the secondary trolley, and an aim of turning a cargo lifted by a main hook is further achieved. Therefore, a phenomenon that a four-beam double-trolley mode is adopted for turning is avoided, the dead weight of the crane is reduced, and the construction cost and energy consumption of the equipment are reduced.
Description
technical field:
The utility model relates to a kind of monkey, particularly a kind of bag hoisting crane finger small car that turns over.
background technology:
The monkey that generally comprises major-minor two cover lifting mechanisms, two cover lifting mechanism rigid arrangement can only realize the relative motion of vertical direction at the suspension centre of trolley frame Shang，Liang Ge mechanism, can not realize the relative motion of horizontal direction.For completing the hoisting crane that turns over bag (tank) action, must major-minor lifting mechanism being engaged in vertical and horizontal direction all will have relative motion to realize, conventional hoist need arrange two dollies and is arranged on two girders and two auxiliary girders (four beams) for this reason, on two girders, main carriage is set, on girder track, move, main hoisting mechanism is set on main carriage, separately have on two auxiliary girders (auxiliary girder is parallel with girder, same long) secondary dolly is set, on auxiliary girder track, move, on secondary dolly, auxiliary hoisting mechanism is set.Hoisting crane work time is lifted by crane slag ladle with main hook, and after the certain altitude of slinging, with the auxiliary hook slag ladle bottom hanger of slinging, in lifting, secondary dolly moves on one side on auxiliary girder, reaches the object of tumble ladle or slag ladle.This hoisting crane is from great, and cart drive motor power is also large, and not only equipment manufacturing cost is high, and the operating energy consumption of equipment is also large.
utility model content:
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of bag that turns over to use hoisting crane finger small car, can reduce crane facility cost and reduce the energy consumption in equipment running process.
Above-mentioned object realizes by following technical scheme:
Turn over bag hoisting crane finger small car, be included in the female dolly moving on girder track, on described female dolly, be provided with sub-trolley travelling track, on described sub-trolley travelling track, be provided with sub-dolly, described sub-trolley travelling track and described girder parallel track, on described female dolly, be furnished with female hoisting mechanism for trolley, on described sub-dolly, be furnished with sub-hoisting mechanism for trolley.
The described bag that turns over is used hoisting crane finger small car, and described female dolly and sub-dolly are respectively arranged with operating unit, and described operating unit comprises motor one, and described motor one is by retarder one connection for transmission axle one, and described transmission shaft one connects female car wheel.
The described bag that turns over is used hoisting crane finger small car, and described female hoisting mechanism for trolley comprises motor two, and described motor two connects two cover roll devices one by retarder.
The described bag that turns over is used hoisting crane finger small car, and described sub-hoisting mechanism for trolley comprises motor three, and described motor three connects roll device two by retarder three, the other fixed pulley group that is provided with of described roll device two.
Beneficial effect:
The utility model is provided with separately lifting mechanism on sub-dolly, and sub-dolly is arranged on the track of female dolly, female dolly moves on two girders, and the lifting mechanism of female dolly and the suspension centre of sub-hoisting mechanism for trolley can be realized the relative motion of horizontal direction to realize the object of the main hook institute hoisting thing of tumbling.Avoided like this realizing turning over the pattern that bag must adopt four beam double trolley, reduced the deadweight of hoisting crane, reduced equipment manufacturing cost and energy consumption.
