The method is unstable in hoisting and belongs to illegal operation. The other method is that a guide chain is placed at the upper part of a hung part from the lower part of the enterprise plant girder, and an object is manually pulled or electrically hoisted to hoist or drop equipment parts, so that the work is complicated, and the hoisting and hoisting of the parts are difficult.
SUMMERY OF THE UTILITY MODEL
To the problem, an object of the utility model is to provide a lifting device for overhaul of the equipments under the factory building roof beam, the work of hoisting is carried out to the equipment unit under the realization factory building roof beam.
In order to achieve the purpose, the technical scheme of the lifting appliance for overhauling equipment under the plant girder of the utility model comprises a lifting appliance body, one end of the lifting appliance body can be extended into a first pre-lifting device, a second pre-lifting device and a third pre-lifting device at the lower part of the plant girder, one end of the lifting appliance body extended into the lower part of the plant girder is fixedly connected with a lifting hook so as to be connected with the first pre-lifting device and the third pre-lifting device for hanging a steel wire rope to finish lifting, and the middle part of the lifting appliance body is fixedly connected with a main hook lifting nose and an auxiliary hook lifting nose according to the positions; the other end of the lifting appliance body is additionally provided with a balance weight, and the balance weight selects a reasonable balance weight according to the self weight of the lifting appliance body and the positions of the main hook lifting nose and the auxiliary hook lifting nose by utilizing the lever principle.
When the hoisting machine is used for hoisting, the upper part of the second steel wire rope is connected with the main hook 7 of the crane, the lower part of the second steel wire rope is connected with the hoisting nose of the main hook, the upper part of the third steel wire rope is connected with the auxiliary hook of the crane, the lower part of the third steel wire rope is connected with the hoisting nose of the auxiliary hook, the hoisting machine is started, the main hook of the crane and the auxiliary hook of the crane are controlled.
Preferably, the lifting appliance body in the lifting appliance for overhauling equipment below the plant girder is I-shaped steel so as to ensure the sufficient strength and rigidity of the lifting appliance.
Preferably, the lifting appliance body in the lifting appliance for overhauling equipment below the plant girder is H-shaped steel so as to ensure the sufficient strength and rigidity of the lifting appliance.
Preferably, the distance between the main hook lifting nose and the auxiliary hook lifting nose in the lifting appliance for overhauling equipment under the plant girder is consistent with the distance between the main hook lifting nose and the auxiliary hook lifting nose of the crane, so that the lifting verticality of the two steel ropes during lifting is ensured.
Preferably, the balance weight and the lifting appliance body in the lifting appliance for overhauling equipment under the plant beam are arranged in a sliding way, so that the position of the balance weight can be conveniently adjusted, and the balance weight can be conveniently unified to be used for lifting various equipment with different weights.
The utility model has the advantages that: the utility model provides a bridge crane for overhaul of equipment utilizes the maintenance in the factory building to overhaul under the factory building roof beam, utilizes main auxiliary hook combined operation, goes deep into factory building roof beam lower part space through this hoist and hangs out or hang into the equipment part, plays the effect of quick maintenance, has solved the overhaul of equipment under the factory building roof beam and has lifted by crane difficultly, and maintenance time is long, consume the problem that manpower, material resources are big, has improved maintenance efficiency greatly.
