Abstract
The utility model provides a novel drum hoisting mechanism, composed of a drum 2, two speed reducers 1 and a motor 4, which is characterized in that two ends of the drum 2 are arranged with two open gears 5, wherein each open gear 5 is meshed with a drive gear on a speed reducer 1, the two speed reducers 1 are driven synchronously by a frequency variable motor 4, the high speed shaft of the speed reducers 1 is provided with two hydraulic block brakes 3 with manual release function, while one brake is a working brake and the another brake is a safety brake, and the aforementioned arrangement forms a hoisting mechanism of a hoisting point, the hoisting mechanisms of hoisting points can be laminated to form a hoisting mechanism of multiple hoisting points. The hoisting mechanism has safety, reliability, high hoisting capacity, compact structure, small volume, simple manufacture, simple installment and simple transmission, having improved performance.
Description
Technical field
The utility model belongs to the weight-lifting equipment technical field, relates to a kind of novel winding drum lifting mechanism of industrial circle large-sized object lifting jobs such as water conservancy and hydropower, lifting transportation, metallurgy.
Background technology
The tradition lifting mechanism is each suspension centre by a reel respectively through a cover exposed gear, a retarder, by a direct motor drive, drives a cover running block by steel rope.Every retarder high speed shaft disposes the drg of a cover or two cover hydraulic block formula band manual releasing functions, simple structure, but following shortcoming is arranged:
One, load-carrying ability deficiency: load-carrying ability is restricted, and when a heavy lift was very big, the drive system of being made up of an electrical motor, a cover driving device was to fail to satisfy requirements.
Two, structure is huge: for meeting design requirement, driving device is very huge, causes the entire equipment size big, is not easy to make, installs, transports.In some remote mountain areas, can't transport at all.
Summary of the invention
For solving the difficult problem of large-tonnage weight-lifting equipment load-carrying ability deficiency, the utility model has designed a kind of novel winding drum lifting mechanism, this lifting mechanism has more safe and reliable, crane capacity is strong, compact conformation, volume is little, is convenient to the super performance making, install and transport, thus perfect properties of product.
For achieving the above object, this utility model has adopted following technical scheme:
Described novel winding drum lifting mechanism is made of reel, retarder, electrical motor, it is characterized in that reel two ends configuration exposed gear, the driving gear engagement of being joined on each exposed gear and the retarder, two retarders are driven simultaneously by adjustable frequency motor, dispose the drg of two cover hydraulic block formula band manual releasing functions at the retarder high speed shaft, one cover is service brake, and another set of is sure brake; The lifting mechanism of a Heave Here is formed in above-mentioned configuration.
Described novel winding drum lifting mechanism also can be formed the lifting mechanism mutual superposition of a Heave Here lifting mechanism of a plurality of Heave Heres.
Because adopt aforesaid technical scheme, the utility model produces following good effect:
This lifting mechanism has more safe and reliable, and crane capacity is strong, compact conformation, and volume is little, is convenient to the super performance making, install and transport, thus perfect properties of product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1: 1-retarder; 2-reel; 3-drg; 4-electrical motor; 5-exposed gear.
The specific embodiment
In conjunction with Fig. 1, novel winding drum lifting mechanism of the present utility model is made of reel 2, retarder 1, electrical motor 4, it is characterized in that reel 2 two ends configuration exposed gear 5, the driving gear engagement of being joined on each exposed gear 5 and the retarder 1, two retarders 1 are driven simultaneously by adjustable frequency motor 4, drg 3, one covers that dispose two cover hydraulic block formula band manual releasing functions at retarder 1 high speed shaft are service brake, and another set of is sure brake; The lifting mechanism of a Heave Here is formed in above-mentioned configuration.
Heave Here, is driven by two frequency conversion motors 4 respectively through two cover exposed gears 5, two retarders 1 simultaneously by a reel 2, drives one by steel rope and overlaps running block.Two motors (4) connects with the high speed shaft of two retarders 1 by the brake wheel coupler, and the slow-speed shaft of retarder 1 is equipped with driving gear respectively and two open gearwheels, 5 engagements that link together with reel, and drive reel 2 is the axle rotation with the drum shaft.
Novel winding drum lifting mechanism of the present utility model also can be formed the lifting mechanism mutual superposition of a Heave Here lifting mechanism of a plurality of Heave Heres, increases bigger hoisting capacity.
Claims (2)
1, a kind of novel winding drum lifting mechanism is made of reel (2), retarder (1), electrical motor (4), it is characterized in that: reel (2) two ends configuration exposed gear (5), the driving gear engagement of being joined on each exposed gear (5) and the retarder (1), two retarders (1) are driven simultaneously by adjustable frequency motor (4), dispose the drg (3) of two cover hydraulic block formula band manual releasing functions at retarder (1) high speed shaft, one cover is service brake, and another set of is sure brake; The lifting mechanism of a Heave Here is formed in above-mentioned configuration.
2, according to the described novel winding drum lifting mechanism of claim 1, it is characterized in that: the lifting mechanism that also the lifting mechanism mutual superposition of a Heave Here can be formed a plurality of Heave Heres.
