Abstract
本实用新型提供一种新型卷筒起升机构，由卷筒2、减速器1、电动机4构成，其特征在于卷筒2两端配置开式齿轮5，每个开式齿轮5与减速器1上所配的主动齿轮啮合，两个减速器1由变频电动机4同时驱动，在减速器1高速轴配置有两套液压块式带手动释放功能的制动器3，一套为工作制动器，另一套为安全制动器；上述配置组成一个起吊点的起升机构，还可将一个起吊点的起升机构相互叠加组成多个起吊点的起升机构。该起升机构具有更加安全可靠，起吊能力强，结构紧凑，体积小，便于制造、安装与运输的良好性能，从而完善了产品性能。
The utility model provides a new reel lifting mechanism, which is composed of a reel 2, a reducer 1 and a motor 4. It is characterized in that open gears 5 are arranged at both ends of the reel 2, and each open gear 5 is connected with the reducer 1. The driving gears on the gear mesh, and the two reducers 1 are simultaneously driven by the variable frequency motor 4. The high-speed shaft of the reducer 1 is equipped with two sets of hydraulic block brakes 3 with manual release function, one set is a working brake, and the other set It is a safety brake; the above configuration forms a lifting mechanism of one lifting point, and the lifting mechanism of one lifting point can also be superimposed to form a lifting mechanism of multiple lifting points. The hoisting mechanism is safer and more reliable, has a strong hoisting capacity, is compact in structure, small in size, and is easy to manufacture, install and transport, thereby improving product 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.
