Technical field
The utility model is usually directed to be used for the driving mechanism of rotary drum grain slag dehydration equipment.More specifically, the utility model relates to the rotary drum driving mechanism with at least two motors.For example, can in the rotary drum dehydration equipment of the slag granulation system of ironmaking equipment (for example, blast furnace, Corex stove or Finex stove), use this driving mechanism.
Background technology
In by motor-driven grain slag dehydration equipment, typically use variable-frequency motor.In order to optimize dehydration procedure, control the rotary speed of rotary drum according to the water level of moment of torsion and rotary drum inside.The moment of torsion that acts on the rotary drum calculates based on current of electric.The rotary speed of rotary drum has a direct impact the moisture of granule content in the water route and dehydration back grain slag.
China utility model CN 201558604U discloses a kind of rotary drum driving mechanism with two motors.This rotary drum driving mechanism further comprises: have the three-ring speed reducer of two power shafts that engage with motor by clutch, the coupling that is connected with sprocket wheel with output shaft with three-ring speed reducer.Sprocket wheel comprises chain wheel and drives the chain of rotary drum itself.In the situation that rotary drum blocks, two motors can move simultaneously, and accumulated slag provides more high pulling torque in the rotary drum in order to remove.
According to CN 201558604U, the power shaft of three-ring speed reducer and the clutch coupling between the motor are the sliding-type clutches, and each clutch is made up of slipper on the corresponding power shaft that is fixed on decelerator and the non-slipper that is fixed to the driving shaft of corresponding motor.Slipper fixes by bolt.
For the sliding-type clutch, can only carry out the joint and the disengaging of mechanical connection at the scene usually manually, in this process, equipment can not turn round.This causes when the following shortcoming of using as being run into during disclosed driver element in above-mentioned utility model patent.
At first consider this situation: rotary drum is in operation and carry out dehydrating operations, and an energising in two motors provides mechanical output.(a sliding-type clutch engages another disengaging).Hereinafter, the energising motor is called " work drive motor ", and simultaneously, another motor is called " standby motor ".This is the operator scheme that CN 201558604U is recommended.
The purpose of this system is when the slag flow increases, should start standby motor, so that some additional torque to be provided on rotary drum.Realize that with this system the unique channel of this effect will be that rotary drum is out of service by the time, manually engage the slip-clutch of standby motor, start two motors then to drive rotary drum.Yet, in practice, do not allow rotary drum in dewatering operation course, to stop, because this will block rotary drum (rotary drum accumulated slag accident).This accident is very serious for whole granulation apparatus, because can't handle grain slag again.
Another kind of situation is that work drive motor produces fault, and standby motor can't start and bear load immediately, and rotary drum will stop.Then, can standby motor be engaged with decelerator by manually engaging respective clutch.With the same in situation before, whole granulation apparatus can't move in the reason process herein.
Therefore, if only a clutch engages, the function of so this driver element is identical with the function of the driver element that only has a motor.The benefit of the system of CN 201558604U only is, may reduce the duration of major accident (rotary drum obstruction).
In addition, if engage two slip-clutches, two motors are connected to each other via decelerator so.Therefore, if motor produces fault owing to mechanical problem and it can't rotate freely, it will be with extra moment of torsion antagonism work drive motor so.This will influence the rotary speed of rotary drum, and it finally influences the moisture of the granule content in the water route and the back grain slag that dewaters.
The utility model content
A purpose of the present utility model provides a kind of rotary drum driving mechanism, wherein, overcomes or reduces above-mentioned shortcoming at least.
The driving mechanism that is used for rotary drum grain slag dehydration equipment comprises: the output shaft that gearbox, described gearbox have at least one power shaft and can mechanically engage with dewatering drum; And first and second motors that operationally engage by first and second clutches and described at least one power shaft respectively.According to the utility model, first and second clutches comprise freewheel clutch, or freewheel clutch.
Further, gearbox is disposed on the identical base with first and second motors, and base is as the fixed frame of rotary drum driving mechanism.
As will be appreciated, if gearbox than the driving shaft of corresponding motor faster rotatably (on of two possible direction of rotation), each freewheel clutch breaks away from the driving shaft of corresponding motor and power shaft so.Except as otherwise noted, otherwise each freewheel clutch only is passed to gearbox with moment of torsion from corresponding motor on a direction of rotation.Freewheel clutch can be unidirectional or double rolling key clutch.The direction that surmounts of mono-directional overrun clutch is fixed.By double rolling key clutch, can on two direction of rotation, on power shaft, apply moment of torsion, but on output shaft, not apply moment of torsion.Therefore, for double rolling key clutch, surmount direction unlike for mono-directional overrun clutch, limiting.By according to rotary drum driving mechanism of the present utility model, rotary drum only rotation in one direction in operating process thus.For rotary drum, in maintenance process, also can only rotate in one direction.The joint of freewheel clutch and disengaging are depended on the rotary speed difference between direction of rotation and driving and the driven member and are automatically occurred.Do not need as manually engaging or disconnecting clutch in the prior art.
Preferably, in the transmission system between clutch and dewatering drum brake is installed.The function of this brake is when disconnecting two motors, to avoid rotating freely of rotary drum.
According to a preferred implementation of the present utility model, the rotary drum driving mechanism comprises sprocket wheel, and described sprocket wheel has the main shaft that mechanically engages with output shaft and is used to drive the chain of dewatering drum with at least one.Between rotary drum and gearbox, can use other transmission device to replace sprocket wheel.
Preferably, mechanically engage each other with the main shaft of sprocket wheel by the output shaft of Cardan shaft gearbox.Cardan shaft preferably includes the rotation key, and this rotation key has universal joint at every end, with the axiality between the main shaft that allows output shaft of gear-box and sprocket wheel and the variation of distance.
Gearbox can advantageously comprise single power shaft, and this power shaft has first end and second end, with first clutch with first end and first motor engage, with second clutch with second end and second motor engage.Alternately, can provide power shaft separately, with motor and gearbox engaged.
First and second motors can have identical rated power.If a normally standby motor of motor and only using in emergency so also can have dissimilar motors.
Preferably, gearbox is disposed on the identical base with first and second motors.
Gearbox is decreased to the lower speed of output shaft with the higher speed of power shaft, increases moment of torsion in this process.Gearbox can advantageously comprise helical gear or Cylindrical gear actuator.Additionally or alternately, gearbox can comprise the gearbox that is suitable for this purpose of three-ring speed reducer or any other type.
A preferred aspect of the present utility model relates to a kind of grain slag dehydration equipment (for example, the grain slag dehydration equipment of slag granulation equipment), and it comprises dewatering drum and common aforesaid rotary drum driving mechanism, and it mechanically engages with the output shaft of gearbox.
Available two motor operation rotary drum driving mechanisms that in operating process, move.Then, two motors load sharing under the control of electric-control system.Common two clutches all engage.If a motor produces fault, so corresponding clutch disconnects, and the motor that produces fault can not apply extra load to work drive motor thus.
As an alternative, a motor can be used as work drive motor, and simultaneously, another is as standby motor.In this case, the freewheel clutch of standby motor breaks away from, and standby motor can not produce any influence to the remainder of rotary drum driving mechanism.
If the slag flow velocity increases, can connect standby motor and start it thus to be rotated.Standby motor only when its speed reaches the speed of work drive motor, begins to bear load.This means, but standby motor No Load Start, and this is very favorable.
If work drive motor produces fault in operating process, so, after detecting the fault of work drive motor, but the standby motor of demand working.The same with situation before, standby motor only when its speed (multiply by the speed reducing ratio of gearbox) when reaching the speed of rotary drum, begins to bear load.This means, but standby motor No Load Start, and, can keep rotation in the process of the conversion of rotary drum between two motors.
In all above-mentioned situations, freewheel clutch does not need people's participation owing to its frame for movement obtains to engage and break away from.When needing, but therefore standby motor No Load Start, does not have special requirement to the control module of controlling motor.If a motor inoperation, this additional torque that can not cause another motor to bear so.

Description of drawings
Pass through case description preferred implementation of the present utility model referring now to accompanying drawing, wherein:
Fig. 1 is the side view according to the slag dehydration equipment that comprises the rotary drum driving mechanism of a preferred implementation of the present utility model;
Fig. 2 is the vertical view of the slag dehydration equipment of Fig. 1.
The specific embodiment
As an example, Fig. 1 and Fig. 2 show the grain slag dehydration equipment 10 of the slag granulation equipment that is used for blast furnace.Dehydration equipment 10 comprises the dewatering drum 12 that mechanically engages with rotary drum driving mechanism 14.
Rotary drum driving mechanism 14 comprises two motors 16,18 with same size.In Fig. 1,, only show in the motor 16,18 for the clearly reason of figure.Operating electrical machines 16,18 simultaneously, perhaps, alternately, an operation, another standby (in course of normal operation) simultaneously.If a motor-driven rotary drum is only arranged, so,, can start another motor if need more moments of torsion or work drive motor to produce fault.
Rotary drum driving mechanism 14 further comprises helical gear gearbox 20, and it has single power shaft 22 and output shaft 24.Power shaft 22 has two ends, and every end is via a connection in freewheel clutch 26,28 and two motors 16,18.Output shaft 24 mechanically engages with the main shaft 30 of the sprocket wheel 32 of dewatering drum 12.Realize this mechanical engagement by Cardan shaft 34, an end of Cardan shaft 34 is connected with the output shaft 24 of gearbox 20 via first universal joint, and the other end is connected with the main shaft 30 of sprocket wheel via second universal joint.The variation of the axiality between the main shaft 30 of Cardan shaft 34 permission output shaft of gear-box 24 and sprocket wheel 32.This is very useful, because gearbox 20 is not installed on the identical base plate with sprocket wheel 32.The sprocket wheel that will comprise the chain 38 of main shaft 30 and driving dewatering drum 12 is installed on first base 35.Motor 16,18 and gearbox 20 are installed on second base 36, and making does not need Cardan shaft in the coupling between motor 16,18 and the gearbox 20.
Freewheel clutch 26,28 is mono-directional overrun clutch preferably.Consider that as shown in the figure rotary drum driving mechanism is typically worked out of doors and near blast furnace, so, need the joint of clutch and break away between fast and conversion reliably.Therefore, think that the use of freewheel clutch is a best solution.The clutch of other type (for example, the electromagnetic clutch of Long-distance Control, or have the clutch of hydraulic pressure or pneumatic actuator) does not meet application demand usually.Understand non-, freewheel clutch 26,28 does not need special control panel, and, be reliable in the heavy industry environment.
The operator scheme that two kinds of possible rotary drum driving mechanisms 12 are arranged basically.In first operator scheme, two motors 16,18 move in normal operating process.Control module is controlled two motors 16,18 by this way, makes it share the load that is applied by rotary drum 12.Two freewheel clutches 26,28 are in engagement state in normal operating process.If one in the motor 16,18 produces fault and slower rotatably, so, corresponding freewheel clutch breaks away from, and will produce the motor and the transmission system disengaging of fault thus.
In second operator scheme, once only there is one in the motor 16,18 to work.So, this motor is called work drive motor.Another motor is held standby.The freewheel clutch of work drive motor engages, and the freewheel clutch of standby motor breaks away from.(for example, when the slag flow increases) can start standby motor when the more driving torque of needs.Because freewheel clutch, but standby motor No Load Start.Standby motor only when its speed reaches the speed of work drive motor, begins to bear load.When work drive motor produces fault or suspects that it will produce fault, also can start standby motor.
