Description
Technical field
The utility model belongs to mechanical technical field, go-home converter drive unit when disclosing a kind of main transmission outage.
Background technology
When accident has a power failure or during the outage of main drive system, and there are situations such as the fire door dry slag is too much in the production of existing steel-making converter, and body of heater often is difficult to be returned to voluntarily the zero degree position, and this moment is if brake failure then industrial accident may take place.For this reason, be necessary to set up go-home drive unit, so that under the situation of main drive motor outage, body of heater is returned to the zero degree position.At present, the converter inclining device mostly is not equipped with standby drive unit both at home and abroad, some converter is both at home and abroad adopted by the gas motor by speed reduction unit, sprocket wheel chain, swivel joint and tilting mechanism step-down gear engages drive and disengagement, and the standby drive unit drive line of this kind complexity, structure are not compact.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of current failure emergency standby converter drive unit, and the letter of the utility model structure is skilful, can be implemented under main transmission power failure or the system cut-off state, makes body of heater be returned to the zero degree position.
The utility model structure realizes by following manner: it is made up of propulsion source, transmission reduction box and shaft coupling, wherein, on the output shaft in the transmission reduction box electromagnetic clutch is installed, and its secondary part links to each other with output gear in the reduction box by connecting parts.Propulsion source and transmission reduction box direct connection, the output shaft of transmission reduction box links by the high speed shaft that is positioned at the main drive motor opposite on shaft coupling and the converter tilting mechanism step-down gear, constitutes the supplementary unit that main transmission outage converter drives.Stopper on outage drive unit and the converter tilting mechanism step-down gear is installed on the same support, and support is installed on the casing of tilting mechanism step-down gear by connecting parts.Standby ups power links to each other with the motor of described electromagnetic clutch and propulsion source.
When accident power failure or the outage of main drive system, by of motor and the electromagnetic clutch power supply of standby ups power to drive unit medium power source, the master and slave part of electromagnetic clutch is engaged, propulsion source rotates through the high speed shaft that the transmission reduction box drives the converter tilting mechanism step-down gear, is returned to the zero degree position thereby drive body of heater.
And under normal circumstances, the electromagnetic clutch that is contained in the standby drive unit in the transmission reduction box is in off-position, be in disengaged condition under the effect of portion's spring force within it of the master and slave part of clutch coupling, the high speed shaft of converter tilting mechanism step-down gear can not drive standby drive unit and rotate.
Description of drawings
Fig. 1 is a vertical view of the present utility model.
Fig. 2 is a front view of the present utility model.
Among the figure, part 1 is a propulsion source, and part 2 is that (wherein, 2-1 is an electromagnetic clutch to the transmission reduction box, 2-2 is an output gear), part 3 is shaft couplings, part 4 is supports, part 5 be the tilting mechanism step-down gear (wherein, 5-1 is a main drive motor, and 5-2 is a stopper, and 5-3 is a high speed shaft).
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
With on the output shaft in the transmission reduction box 2 of propulsion source 1 motor direct connection electromagnetic clutch 2-1 is installed, the secondary part of clutch coupling links to each other by the output gear 2-2 in connecting parts and the transmission reduction box 2, the output shaft of transmission reduction box 2 links by the high speed shaft 5-3 that is positioned at main drive motor 5-1 opposite on shaft coupling 3 and the tilting mechanism step-down gear 5, constitutes the supplementary unit that main transmission outage converter drives.Stopper 5-2 on transmission reduction box 2 and the tilting mechanism step-down gear 5 is installed on the same support 4, and support 4 is installed on the casing of tilting mechanism step-down gear 5 by connecting parts.Standby ups power links to each other with the motor of propulsion source 1 with described electromagnetic clutch 2-1.
Propulsion source 1 can be a motor, can also be oil motor or gas motor; If oil motor or gas motor provide power with hydraulic efficiency oil or with compressed gas.Transmission gear box can be a worm and gear, can also be cylindrical gear; 2 of propulsion source 1 and transmission reduction boxes also can link by shaft coupling.
When unexpected power failure or the outage of main drive system, earlier to the coil power supply of electromagnetic clutch 2-1, make the driving and driven part of clutch coupling be in engagement state by standby ups power; Then by of the motor power supply of standby ups power to propulsion source 1.High speed shaft 5-3 by transmission reduction box 2, shaft coupling 3, tilting mechanism step-down gear 5 rotates, and is returned to the zero degree position thereby drive body of heater.Before the rotating furnace, also should guarantee that stopper is in open mode by the stopper 5-2 power supply of standby ups power on tilting mechanism step-down gear 5.
Under the normal circumstances, coil on the electromagnetic clutch 2-1 active part is in off-position, be in disengaged condition under the effect of portion's spring force within it of its driving and driven part, the rotation that main drive motor 5-1 drives high speed shaft 5-3 on the tilting mechanism step-down gear 5 can not pass to the output gear 2-2 in the transmission reduction box 2, and standby drive unit does not turn round.
The letter of the utility model structure is skilful, in light weight, cost is low and convenient for installation and maintenance, can be widely used in converter rotating furnace usefulness when having a power failure of the various type of furnaces of steelworks, also is applicable to other need need rotating machinery when main motor stall production field.
