Abstract
The utility model discloses a mine elevator driven by a permanent magnetic synchronous motor, which includes a drive motor, a reeling roller and a brake system and is characterized in that the drive motor is the permanent magnetic synchronous motor; a permanent magnetic synchronous motor shaft is directly connected with the reeling roller through a coupling; the permanent magnetic synchronous motor has an input DC voltage of 660V, a maximum output power of 1300kW and a rated rotational frequency of 53 rpm. The utility model employs a low-voltage high-power low-rotation speed permanent magnetic synchronous motor to greatly improve the performance indexes of electric transmission of the mine elevator; and it is not transmitted by a gearbox, thus greatly reducing the manufacturing cost of the transmission system, decreasing the occupation area, having easy installation and low maintaining expenses, realizing gearless transmission of the mechanical equipment and avoiding harmonic wave pollution of the high-voltage electric control to the electrical network.
Description
Technical field
The utility model belongs to mine hoisting equipment.
Background technology
Mine hoist is mainly used in ground, mine vertical shaft and does the usefulness that promotes material, personnel and equipment.Also can be used for the inclined gallery, down-hole and promote transportation and mine kibble hoist.It mainly is made up of dragging motor, serving cylinder and brake system.At present, the driving style of mine hoist has two kinds: a kind ofly drag for exchanging, a kind ofly to drag for direct current.What wherein be most widely used is to exchange wire wound asynchronous motor to drag, and exchanges to drag fairly simple, equipment and erected cost is low, building area is little.But under the present condition of China, this interchange drags the restriction of the capacity of being subjected to, electric current, and maximum power draw is about 1000kw.So large-scale hoister adopts high pressure, DC machine more.This type of electric machine speed regulation performance is good, degree of automation is high, but also is faced with more problem simultaneously.As: the high voltage converter capacity is bigger, and the proportion that accounts for whole net capacity is comparatively remarkable, and high voltage converter produces harmonic pollution to electrical network; Output harmonic wave mainly is to cause the additional heating of motor to the influence of motor, causes the extra temperature rise of motor, and motor often wants derate to use.In addition, owing to cause the distortion of electrical network output wave shape, increase the repetitive peak voltage of motor, influence electrical machine insulation, harmonic wave also can cause motor torque ripple, and noise increases.High voltage converter usually needs to adopt the water cooled mode to cool off.This water-cooling pattern brings inconvenience for the use of low-pressure high-power frequency converter.Especially the open air use of northern area can bring problems, and the processing of water, seepage, problem such as antifreeze are all used to the user and brought multiple inconvenience.The DC motor price is expensive, and maintenance is big, manufacturing process is complicated, need special rectifying device, and during with the thyristor units decompression speed, along with reducing of thyristor trigger angle, power factor reduces.
Summary of the invention
In order to address the above problem, the direct current that the utility model proposes a kind of low-pressure high-power power drags mine hoist.
For achieving the above object, the technical scheme that the utility model is taked is that it comprises dragging motor, serving cylinder and brake system, it is characterized in that, described dragging motor is a permagnetic synchronous motor, and permagnetic synchronous motor axle and serving drum shaft are by the coupler direct connection; The input direct voltage of described permagnetic synchronous motor is 660V, Maximum Power Output 1300KW, 53 rev/mins of rated revolutions.
The utility model has the advantages that:
1, owing to adopted the slow-revving permagnetic synchronous motor of low-pressure high-power, the performance figure of mine hoist Electrified Transmission have been improved significantly.
2, owing to without the change speed gear box transmission, reduced the manufacturing cost of driving system significantly, floor area is little, installs simply, and maintenance cost is low.
3, realize the gearless driving of mechanical equipment, noise is low.
4, avoided the harmonic pollution problem of high-pressure electric control to electrical network.
5, equipment package does not need water-cooled, brings convenience to the users.
Description of drawings
Fig. 1 is the scheme drawing of the well gig of permagnetic synchronous motor.
Marginal data: 1-disc brake system, 2-serving cylinder, 3-coupler, 4-permagnetic synchronous motor.
The specific embodiment
As shown in Figure 1, the utility model is the disc braking system 1 that is equipped with on serving cylinder 2, and the axle of permagnetic synchronous motor 4 passes through coupler 3 direct connections with the axle of serving cylinder 2.The input direct voltage of described permagnetic synchronous motor 4 is 660V, Maximum Power Output 1300KW, 53 rev/mins of rated revolutions.
Claims (1)
1. mine hoist that drags with permagnetic synchronous motor, it comprises dragging motor, serving cylinder and brake system, it is characterized in that, and described dragging motor is a permagnetic synchronous motor, and permagnetic synchronous motor axle and serving drum shaft are by the coupler direct connection; The input direct voltage of described permagnetic synchronous motor is 660V, Maximum Power Output 1300KW, 53 rev/mins of rated revolutions.
