Abstract
The utility model provides a crane adopting a three-stage planetary reducer, relating to ladle cranes and solving the technical problem that crane bridges of existing three-stage reducer hoisting mechanisms cannot bear the horizontal bending stress, cannot enable the cart wheel pressures to be distributed uniformly. The three-stage planetary reducer is characterized in that an end beam of a bridge is formed by hinging two outside end beams and an inside end beam; a main beam is formed by two inside main beams and two outside main beams; the two inside main beams are rigidly connected by the inside end beam; the outside main beams and the inside main beams are hinged together by the outside end beams and the inside end beam with hinged shafts. The four-beam six-rail bridge type ladle crane has the advantages and beneficial effects that the end beam of the bridge does not bear the horizontal bending stress but can enable the cart wheel pressures to be distributed uniformly; the crane has the advantages of simple structure, few drive links and low failure rate and is convenient to use and maintain.
Description
Technical field
The utility model relates to ladle carne, particularly adopts the ladle carne of planet three retarders, four beam six rail crane span structures.
Background technology
At present, in the ladle carne of three retarder lifting mechanisms, the crane span structure of the four beam six rail versions that adopt, the flexible end carriage that all adopts made by German MAN company to design, is cut with scissors end carriage is divided into 5 sections by end carriage.This version can guarantee that bridge-frame end-beam does not bear horizontal curvature stress, but cart wheel wheel load skewness.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of hoisting crane that adopts planet three retarders is provided, solve the hoisting crane four beam six rail portal structures of current three retarder lifting mechanisms, can not neither bear horizontal curvature stress, the technical matters that can make again cart wheel wheel load be evenly distributed.
The utility model is achieved through the following technical solutions:
A kind of hoisting crane that adopts planet three retarders, comprise: the crane span structure being formed by end carriage and girder, be arranged on the main carriage on crane span structure, secondary dolly, and main carriage lifting mechanism, the top trolley frame of described main carriage is connected with bottom trolley frame by ball pivot, described main carriage lifting mechanism adopts three retarders to become Chinese character pin-shaped layout, two output shafts of planetary reduction gear are connected with secondary retarder by universal coupling, secondary retarder is connected with reel, electrical motor, drg, planetary reduction gear, secondary retarder, reel is arranged on the trolley frame of top, fixed pulley group is arranged on the bottom trolley frame that is positioned at reel outside, it is characterized in that: the end carriage of described crane span structure forms by end carriage is hinged end carriages and one inner side, two outsides, described girder is comprised of two inner side girders and two outside girders, between two inner side girders, by inner side end carriage, be rigidly connected, between outside girder and inner side girder, pass through outside end carriage, inner side end carriage is hinged with hinge.
The utility model, for four beam six rail bridge ladle carnes, has the following advantages and beneficial effect:
1, because two inner side girders are rigidly connected, hinged by end carriage between outside girder and inner side girder, thus guaranteeing that bridge-frame end-beam does not bear under the prerequisite of horizontal curvature stress, increased the horizontal stiffness of crane span structure.
2, because cart between-wheel spacing is easy to adjust, can guarantee that cart wheel wheel load is evenly distributed, improved the force-bearing situation of workshop steel structure, saved workshop steel structure investment.
Accompanying drawing explanation
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the lateral plan of Fig. 1.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The specific embodiment
As shown in FIG. 1 to 3, a kind of hoisting crane that adopts planet three retarders, comprise: the crane span structure being formed by end carriage and girder, be arranged on the main carriage 10 on crane span structure, secondary dolly 11, and main carriage lifting mechanism, the top trolley frame 1 of described main carriage is connected with bottom trolley frame 5 by ball pivot 6, described main carriage lifting mechanism adopts three retarders to become Chinese character pin-shaped layout, two output shafts of planetary reduction gear 2 are connected with secondary retarder 9 by universal coupling 17, secondary retarder 9 is connected with reel 3, electrical motor 7, drg 13, planetary reduction gear 2, secondary retarder 9, reel 3 is arranged on top trolley frame 1, fixed pulley group 4 is arranged on the bottom trolley frame 5 that is positioned at reel 3 outsides.
Utilize the characteristic of planetary reduction gear double freedom, when in two input shafts of planetary reduction gear, the driving of a certain axle was lost efficacy, by drg by this axle locking, another axle can partly connect smooth operation for a long time, and the equal nonoverload of all mechanisms, under monitoring in real time, can guarantee load safety.It is independent individual that three masters hoist with retarder, and its installation is lower to top trolley frame rigidity requirement, can reduce steel structure weight.Fixed end at two winding drum is equipped with respectively sure brake, for the safe and reliable operation of complete machine provides further protection.
The end carriage of described crane span structure forms by end carriage 12 is hinged end carriages 8 and one inner side, two outsides, described girder is comprised of two inner side girders 15 and two outside girders 14, two inner sides are rigidly connected by inner side end carriage 12 between girders 15, hinged by outside end carriage 8, inner side end carriage 12 use hinges 16 between outside girder 14 and inner side girder 15.
Crane span structure of the present utility model adopts hinged end beam, compares with the flexible end carriage of prior art, guaranteeing that bridge-frame end-beam does not bear under the prerequisite of horizontal curvature stress, has increased the horizontal stiffness of crane span structure; Because cart between-wheel spacing is easy to adjust, can guarantee that cart wheel wheel load is evenly distributed simultaneously, improve the force-bearing situation of workshop steel structure, save workshop steel structure investment.The utlity model has simple in structurely, transmission link is few, failure rate is low, the easy to use and advantage safeguarded.
