Description
Technical field
The utility model belongs to the elevator machinery technical field, relate to a kind of elevator machinery permanent magnetism synchronization gear wheel free spool type jack up unit, particularly a kind of multiple lifting equipments such as hoisting crane, winch, traverse crane and gantry crane that require to have low speed and super large torque characteristics that are applicable to.
Background technology
The jack up unit that has the multiple lifting equipments such as hoisting crane, winch, traverse crane and gantry crane of slow speed of revolution and super large torque characteristics at present generally adopts the Asynchronous Motor Driving gear reduction unit to drive reel and realizes hoisting of weight, and the configuration schematic diagram of this jack up unit as shown in Figure 1.
From accompanying drawing 1 as can be seen, asynchronous dynamo and reel are installed side by side by gear reduction unit, and reel only plays lay winding wire ropes, and the inner space of reel is very big, does not but make full use of.This has just determined the dolly of carrying jack up unit that bigger span will be arranged, and hoist mechanism need take bigger space.
Patent announcement number is CN200995938Y " a kind of car hosit lifting mechanism ", and it is made up of support, HM Hydraulic Motor, reductor, reel, power-transfer clutch, drg, and reductor places in the reel, and reductor reduces 20-30% than traditional design.Though this structure has been saved the installing space of reductor, do not cancel reductor, still adopt the Asynchronous Motor Driving reductor to drive the structure of reel.
The air-gap field of the asynchronous motor that existing jack up unit is used is provided by stator current, and there is copper loss in rotor, makes its efficient and power factor all lower.For the weight that hoists of elevator machinery, the complete process that hoists, the distance that half is arranged is for unloaded, and second half distance is load.Even during load, in most cases load factor is also less than 80% of rated load, nominal load.This load characteristic of hoisting crane has caused asynchronous motor often to run on zero load or light duty.Lower during asynchronous motor efficiency ratio rated load, nominal load when running on zero load or underloading, performance is poorer, has caused very big waste of energy.
The torque that elevator machinery requires when hoisting weight is very big, can reach several thousand to several ten thousand Nm according to the difference of hoisting capacity, and that lifting velocity requires is very low, and the rotating speed of fitness for purpose reel is per minute tens commentaries on classics.The rated speed of rotation of asynchronous motor is higher, torque is less, adopt direct drive mode can't satisfy the requirement of elevator machinery, so can only adopt electrical motor to satisfy the requirement of elevator machinery by the type of drive of gear reduction unit drive reel for low speed, big torque at all.There is following a series of problem in this type of drive:
(1) entire system efficient is low: because gear reduction unit adopts the multi-stage gear speed change, its driving efficiency reduces, and the energy that means the power supply input system has and is decelerated machine greatly and consumes;
(2) system bulk and weight become big: because the existence of gear reduction unit makes the volume and weight of whole elevator machinery jack up unit become big, this has bigger intensity with regard to the crossbeam that requires elevator machinery, and elevator machinery will take up room more;
(3) existence of gear reduction unit makes the total system complex structure, and fault rate is higher;
(4) vibration and noise are serious; Connection between each mechanism and gear-driven existence all will produce vibration and noise;
(5) adjustment is difficult in maintenance: gear reduction unit needs regularly to add lubricated wet goods, brings very big inconvenience to use;
In sum, existing elevator machinery with jack up unit have that driving efficiency is low, weight greatly, take up room more, vibration and noise is serious, fault rate is higher, adjust defective difficult in maintenance, also caused very big waste of energy simultaneously, so demand improvement urgently.
The utility model content
The purpose of this utility model provides a kind of elevator machinery permanent magnetism synchronization gear wheel free spool type jack up unit, it has solved fundamentally that the driving efficiency that prior art exists is low, weight greatly, take up room more, waste problem such as electric energy, its reasonable in design, volume is little, and is in light weight, material-saving, compare with existing like product that not only cost is low, energy-conservation, significantly improve driving efficiency, and having safe in operation, steadily reliable, rotating speed hangs down and the big advantage of output torque.
The purpose of this utility model is achieved in that this device comprises the bolster that is fixed on the support, the reel that is fixed on the stator of the permagnetic synchronous motor on the pivot shaft and is assembled on the bolster and sways, its technical essential is: with the rotor of described reel as described permagnetic synchronous motor, be fixed on described reel two ends before, before rear side housing utilizes, rear bearing is assembled in respectively on the described bolster, the periphery of described reel is provided with the grooving of lay winding wire ropes, with the outer face of the rear side housing of reel as brake area, attach magnet steel along week in the described reel, the axial length of magnet steel equates with the axial length of stator core, described stator core utilizes axle sleeve and described bolster to be fixed together, the pig-tail wire of stator winding connects external power supply by the pig-tail wire hole on the described bolster, and coder is fixed on the front end cover of described reel.
With the periphery two ends of described reel as brake area, perhaps with the inwall of reel as brake area.
Because the utility model has adopted the reel of permagnetic synchronous motor and jack up unit has been made incorporate version, promptly the rotor of the reel of built-in magnet steel as motor, the inside that stator core on the bolster and stator winding place reel will be fixed on, be assembled into the permanent magnetism synchronization gear wheel free spool type jack up unit that is exclusively used in elevator machinery, so its reasonable in design has been simplified the structure of jack up unit greatly, dwindled and taken up room, volume is little, and is in light weight, material-saving.The air-gap field of this device mainly is to be provided by epitrochanterian magnet steel, and unlike asynchronous motor, air-gap field is provided by stator current, compare with existing like product that not only cost is low, energy-conservation, significantly improve driving efficiency, and have safe in operation, steadily reliable, the low and big advantage of output torque of rotating speed.It has solved fundamentally that the driving efficiency that prior art exists is low, weight greatly, take up room more, waste problem such as electric energy, especially under the operating condition of low speed and underloading, its power savings advantages is more obvious, needs the equipment of low speed, big torque applicable to various elevator machineries and other.Therefore, the permanent magnetism synchronization gear wheel free spool type jack up unit of this new construction is more prone to apply.
