Abstract
The utility model discloses a maintenance crane for a large-scale gantry crane, which is mounted at the top of the main beam of the large-scale gantry crane. The maintenance crane comprises an upright post, a swing mechanism, a cross beam, an electric hoist and a counterweight, wherein the swing mechanism comprises a power swing device, a small gear, a large gear ring, a swing inner ring and a swing bracket; the power swing device drives the small gear to rotate around the fixed large gear ring; the swing bracket and the cross beam fixedly arranged thereon rotate with the small gear; the cross beam swing in a -180 DEG to +180 DEG range; the electric hoist arranged on the cross beam operates along the cross beam, so as to lift and lower objects; and the whole working process of the maintenance crane is controlled through a flashlight door. The maintenance crane has the advantages that the structure is compact; the dead weight is light; the operation is convenient; man-power and material resource waste during the maintenance of the gantry crane can be reduced, so as to save cost; the maintenance time of the gantry crane is shortened; the use efficiency of the gantry crane is improved; and the problem that the large-scale gantry crane which is not equipped with the maintenance crane is inconvenient to maintain is solved.
Description
Technical field
The utility model relates to large-sized gantry and hangs, and particularly the large-sized gantry maintenance of hanging.
Background technology
Large-sized gantry is hung in the process of use; If its electric panel room in-to-in parts the or when parts of dolly need be changed or keep in repair up and down; Need to hang ground to these parts from the girder top, this process need be used lifting appliance, and not installation and maintenance of top are hung like girder; Then will need lot of manpower and material resources to accomplish more changing jobs of parts, have a strong impact on the use of gauntry crane.
The utility model content
The purpose of the utility model provides the maintenance that a kind of large-sized gantry hangs and hangs, and the large-sized gantry that does not have installation and maintenance to hang with solution hangs the problem of inconvenient maintenance.
The purpose of the utility model realizes through following technical scheme:
The maintenance that a kind of large-sized gantry hangs is hung; Comprise column, swing type mechanism, crossbeam, electric block and counterweight, the lower end of said column is fixed on the top of the girder that large-sized gantry hangs, and the upper end is set with butt flange; Said swing type mechanism is arranged on the butt flange of said column; Said swing type mechanism comprises power turning gear, miniature gears, bull gear, revolution inner ring and rotary support, and said bull gear is fixedly connected on the butt flange of said column, rotates in the said bull gear and is provided with the revolution inner ring; The lower end of said rotary support is set with butt flange; Said rotary support is fixedly connected through the butt flange and the said revolution inner ring of its lower end, and said power turning gear is fixedly connected on the butt flange of said rotary support lower end, and said miniature gears is fixedly connected on the output shaft of said power turning gear; And with said bull gear external toothing; Said crossbeam is fixedly installed on the said rotary support, and it is a side of boundary that said electric block is arranged on the said crossbeam with the rotary support, and it is the opposite side of boundary that said counterweight is arranged on the said crossbeam with the rotary support.
Preferably, said power turning gear is a cycloid speed reducer.
Preferably, also be provided with the cat ladder platform on the said column.
The beneficial effect of the utility model is: compact conformation, from heavy and light, easy to operate, cost is practiced thrift in the waste of manpower and materials in the time of can reducing the gauntry crane maintenance, shortens the maintenance time of gauntry crane, improves the service efficiency of gauntry crane.
