Abstract
The utility model provides a casting crane of four-beam, six-rail and soft beam and bridge stand. The utility model has the main characteristic that the hoisting mechanism of the main trolley comprises two sets of motor 401, a coupling 402, a floating shaft 403, a coupling and the braking system 404 with a brake disc, a speed reducer of whole structure 405 positioned between low speed gear and connected with idle gear, a double-drum device 406, a drum coupling 407 positioned between the drum and the speed reducer, and a double fixed pulley group 408. Two sets of motor, the coupling, the floating shaft, the coupling and the braking system with the brake disc are positioned at two sides of the drum device, the fixed pulley group 408 is positioned on the platform of the lower trolley, and the platform of the upper trolley is equipped with a window 409 for convenient installation of the fixed pulley group and passing through the steel wire rope. The utility model has the advantages of lighter self weight of the main trolley, reduction on the parts of the hoisting mechanism, convenient use and maintenance, and safer and more reliable. The utility model is used in steel plant of the large-scale and medium-scale metallurgy enterprises.
Description
Technical field
The utility model belongs to handling machinery, specially refers to a kind of ladle carne of four beams, six rail flexible ends beam bridge framves.
Background technology
At present, German MAN company, the designed big-and-middle-sized ladle carne of Taiyuan heavy industry mainly comprise: the crane span structure and the traveling mechanism of the larger traveller of the flexible end carriage of four beams, six rails, main carriage, secondary dolly, major and minor wheeling mechanism and major and minor lifting mechanism etc.Main carriage is that ball-type is hinged dolly top and bottom.Its lifting mechanism is three Chinese character pin-shaped layouts of retarder, two or four electrical motors drive two input shafts of central reducer unit simultaneously, on two output shafts of central reducer unit, drive the high speed shaft of a two-stage reduction gear respectively, on the slow-speed shaft of two-stage reduction gear, drive a reel by drum coupling by coupler.The major defect that the lifting mechanism arrangement form of this hoisting crane exists: one, reliability is relatively poor, after the coupler between central retarder and the two-stage reduction gear breaks down, can cause the inclination of steel ladle, causes serious accident.Two, scantling of structure is restricted, the outermost from the afterbody of electrical motor to two-stage reduction gear, and its size is bigger, makes that like this trolley frame width dimensions is bigger, therefore causes the left and right sides limit size of suspender to strengthen, thereby is difficult to satisfy the technological requirement of steel mill.Three, parts such as retarder, axle, coupler are more, and fault rate is higher, and maintenance and maintenance workload are big.
Summary of the invention
The purpose of this utility model is to overcome above the deficiencies in the prior art, make improvements, a kind of ladle carne with four beams, six rail flexible ends beam bridge framves of characteristics such as the main carriage deadweight is light, the complete machine manufacturing is installed easily, working service is convenient, and is more safe and reliable is provided.
This practical new technical scheme is achieved in that
A kind of ladle carne of four beams, six rail flexible ends beam bridge framves comprises the crane span structure and the traveling mechanism of the larger traveller of the flexible end carriage of four beams, six rails, main carriage, secondary dolly, major and minor wheeling mechanism and lifting mechanism; Main carriage is hinged top and bottom by ball-type; It is characterized in that: described main carriage lifting mechanism contains the coupler and the brake system of two cover electrical motors, coupler, floating axle, band brake dish, and be provided with idle pulley bonded assembly integral structure retarder between a low speed turbine stage gear, two roll devices, the drum coupling between reel and the retarder, two fixed pulley group; Two cover electrical motors are by the coupler difference connection reducer high speed input shaft of coupler, floating axle, band brake dish, and the output shaft of retarder connects two roll devices by the reel drive coupling; Two roll devices are arranged in the trolley frame middle part, two cover motor arrangement are in the both sides of roll device, fixed pulley is assembled on the trolley platform of bottom, and between electrical motor and roll device, the top trolley platform is offered the convenient window that fixed pulley group and steel wire penetrating are installed.
It and background technology relatively have the following advantages:
1, two of main hoisting mechanism groups of actuating devices connect with idle pulley between the big gear wheel of retarder low speed turbine stage, behind any rooted tooth wheel shaft (removing the low speed turbine stage gear wheel shaft) or motor reel fracture of reductor, an or cover after electrical motor breaks down, the steel ladle that not only can guarantee institute's handling keeps horizontality, unlikely generation serious accident, and can finish a working cycle.
2, because structure self has enough safetys, do not need to install sure brake, simplified control process in reel ends.
3, simple in structure, transmission link is few, and fault rate is low, and the equipment of being convenient to uses and safeguards.
4, outermost size obviously reduces from the electrical motor afterbody to reductor, has reduced the width dimensions of trolley frame, and the deadweight of framing member is alleviated, and suspension hook left and right sides limit size is obviously reduced, and satisfies the technological requirement of steelworks.
