The improved large dumping winch is characterized in that the rack is an L-shaped portal frame; a front stand column is added at the front end of the portal frame so as to form a simple beam supporting structure; and a fixing structure adopting four double force bars, namely a fixing mode adopting tensions bars which incline forwards and backwards, is arranged between a crane beam cantilever and a rear stand column of the L-shaped portal frame. For the improved large dumping winch, the bearing structure is reliable, the occupied area is small, the operation is simple, the cost is low, the automaticity is higher than that of a crane, the adaptability to hoisting speed is strong, the running is stable and safe, the use guarantee property is good, the maintenance rate is low, and parts easy to be damaged are few and cheap.
Description
Technical field
The utility model belongs to the steel industry ironmaking equipment, particularly relates to a kind of hoisting equipment of tumbling that molten iron is used that lifts.
Background technology
The hoisting equipment of tumbling uses the tail position at the steel industry ironmaking equipment, and molten iron in hot-metal bottle and the jar is sling simultaneously, slowly pours in " pig mold ", the crane that replaces equal tonnage, realize that than crane function is more safe, operate safer reliably, belong to the optimization type equipment of crane.
The equipment of tumbling below original 100T all adopts the monomer upright post type, and framework is taller and bigger, no cross-tie point, and poor reliability, safety factor are low.And the above lifting great majority of 100T are considered operational risk in addition, and are most of then adopt traditional boat to hang equipment.Hang the deficiency that equipment uses for remedying boat in this production process, special procure the hoisting equipment of tumbling of wanting 100T-200T.
Summary of the invention
The purpose of this utility model provides a kind of improved large-scale hoisting equipment of tumbling, and to solve traditional equipment of tumbling, in lifting 100T-200T hot-metal bottle operation, promotes safety of operation and technology of dependability problem.
A kind of improved large-scale hoisting equipment of tumbling described in the utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of improved large-scale hoisting equipment of tumbling comprises actuating device, frame, crane beam, travelling car, suspension hook, one group of fixed pulley and traction steel wire rope; Travelling car travels on the crane beam of frame upper end, actuating device and frame are fixed on the driving surface, suspension hook is suspended on the below of travelling car by the traction steel wire rope, and the traction steel wire rope is fastened through the reel of travelling car assembly pulley, one group of fixed pulley and actuating device; It is characterized in that described frame adopts single column the place ahead to add the single supported beam supporting construction of portal frame, adopts four two power bar fixed sturctures, the i.e. fixed forms of oblique forward and backward tension bar between crane beam and single column.
Described actuating device is also controlled the single cover drive configuration that falls for both controlling liter, comprises alternating-current motor/AC motor, retarder, coupler and reel.
Adopt large-scale H shaped steel to become the crane beam of many spokes formula with the steel plate assembly welding.
A kind of improved large-scale hoisting equipment of tumbling described in the utility model is compared with same category of device, load larrying member are reliable, floor area is little, simple to operate, cost is low, than crane degree of automation height, the lifting speed comformability is strong, safety operates steadily, the operational support performance is good, and maintenance rate is low, the few and easily worn part low price of easily worn part.

The specific embodiment
A kind of improved large-scale hoisting equipment structure of tumbling described in the utility model is referring to Fig. 1, and it comprises actuating device 1, frame 3,6, crane beam 8, travelling car 4, suspension hook 5, one group of fixed pulley 2 and traction steel wire rope 7.Travelling car 4 travels on the steel rail for crane of installing on the crane beam 8 that frame 3 upper ends are fixed 9.Actuating device 1 is fixed on the driving surface with frame 3,6.Suspension hook 5 is suspended on the below of travelling car 4 by traction steel wire rope 7, and traction steel wire rope 7 is fastened through the reel of the assembly pulley of travelling cars 4, one group of fixed pulley 2 and actuating device 1.Described frame adopts single column 3 the place aheads to add the single supported beam supporting construction of portal frame 6, adopts four two power bar fixed sturctures, the i.e. fixed forms of oblique forward and backward tension bar at crane beam 8 and 3 on single column.
Described actuating device 1 is also controlled the single cover drive configuration that falls for both controlling liter, comprises alternating-current motor/AC motor, retarder, coupler and reel.
Described alternating-current motor/AC motor adopts metallurgical, lifting class frequency-conversion and speed-regulation motor: the speed governing frequency is 3～100HZ, can free speed governing degree, and speed is decided according to output.Described reducing motor is a hard-tooth surface speed reducer: according to how many definite model and longer service life of lifting tonnage.The electric-control system of actuating device: variable frequency regulating speed control, determine transducer power according to output requirement and motor, reductor configuration, can adopt the permanent torque frequency converter of Siemens 6SE6440 series.The transmission shaft of actuating device and transmission gear: material is an alloy structureal steel, and is after heat treatment counter-bending, wear resisting property is more reliable.
The scope of this Siemens's frequency converter electrical motor maximum frequency setting value: 0-650HZ, the variable-frequency motor frequency adjustment range of the special-purpose YZP series of lifting: 3-100HZ.This variable-frequency motor is when real-world operation, and 3-50HZ is permanent torque operation, i.e. the operating speed of electrical motor speed no matter, and its output torque is constant.Utilize its this characteristic, the frequency converter timing instruction knob by the frequency conversion tank operator's station can make full ladle steadily at the uniform velocity rise when promoting, and can control the flow of ladle to the pig mold pouring molten iron according to the running velocity of chain belt of pig machine.
When empty ladle descended, if still by the descending speed of above-mentioned control ladle, ladle descended slowly, and the time is long, and is unfavorable to continuous production.Speed-regulating instruction button by frequency converter is adjusted to the motor running frequency in 60～100HZ scope.(note: when converter parameter was set, maximum frequency that should electrical motor was set to 100HZ.) variable-frequency motor is an output-constant operation in this scope, frequency rising rotating speed increases, the time decreased that ladle descends.
