Abstract
The utility model relates to a casting crane for lifting a four-beam and six-track bridge frame and a planetary triple speed reducer. The utility model is characterized in that an end beam of a bridge frame adopts a semi-rigid structure, and the end beam is hinged by three segments; an outside main beam and inside main beams are in rigid connection, and the two inside main beams are connected through a pull rod. The wheel spanning ratio of a cart running mechanism is reasonable, the horizontal rigidity of the bridge frame is increased, the problem that a cart gnaws tracks is solved on the structure and the running reliability of the complete vehicle is ensured. The utility model has the characteristics of reasonable wheel spanning ratio, easy installation and manufacture, superior running performance, safety, convenient maintenance, etc., and the utility model can satisfy specific requirements of steel smelting operations, etc.
Description
Technical field
The utility model relates to a kind of ladle carne, especially relates to a kind of four beams, six rail crane span structure ladle carnes.
Background technology
The crane span structure of four beams, the six rail structural shapes that adopted in the ladle carne that domestic four beams, six rail crane span structures and planet three retarders hoist all adopts the flexible end carriage of German MAN TAKRAF design-calculated at present, by hinged end carriage is divided into 5 sections.Though this way has kept the static determinacy characteristic of each part of end carriage, cause wheel to stride than unreasonable, easily gnaw rail, and the trouble point is many.
Summary of the invention
According to as mentioned above, the purpose of this utility model provide a kind of have reasonable wheel stride than the ladle carne that hoists of planet three retarders of four beams, six rail structural shape crane span structures.
For achieving the above object, the ladle carne that the utility model provides a kind of four beams, six rail crane span structures and planet three retarders to hoist, comprise crane span structure, lifting mechanism, trolley frame, it is characterized in that, the end carriage 8 of crane span structure is a semirigid structure, by 3 sections hinged forming, rigid attachment between outside girder 14 and the inboard girder 15 connects by pull bar 12 between the two inboard girders 15.
Crane span structure of the present utility model adopts semi-rigid end carriage, compare with the flexible end carriage of prior art, the wheel of traveling mechanism of the larger traveller is striden than rationally, increased the horizontal stiffness of crane span structure, not only solved cart and gnawed the rail problem from structure, and because end carriage has reduced by two hinge-points, thereby reduced the fault origination point, improved the serviceability of this ladle carne.
Description of drawings
The utility model has 3 accompanying drawings.
Fig. 1 is the ladle carne lifting mechanism front view partly that four beams, six rail crane span structures and planet three retarders hoist;
Fig. 2 is the birds-eye view of crane hoisting mechanism part shown in Figure 1;
Fig. 3 is the lateral plan of crane hoisting mechanism part shown in Figure 1.
Among the figure: the trolley frame of 1-top; The 2-planetary reduction gear; The 3-reel; 4-fixed pulley group; 5-bottom trolley frame; The 6-ball pivot; The 7-wheeling mechanism; The 8-end carriage; 9-level retarder; The 10-sure brake; The secondary dolly of 11-; The 12-pull bar; The 13-drg; 14-outside girder; The inboard girder of 15-.
The specific embodiment
As Fig. 1～shown in Figure 3, the ladle carne that the utility model four beams, six rail crane span structures and planet three retarders hoist is made up of main carriage, traveling mechanism of the larger traveller, crane span structure, secondary dolly etc.Major and minor dolly comprises lifting mechanism, operating unit, trolley frame.Main carriage connects top trolley frame 1 and bottom trolley frame 5 by ball pivot 6.The end carriage 8 of crane span structure is a semirigid structure, and by 3 sections hinged forming, rigid attachment between outside girder 14 and the inboard girder 15 connects by pull bar 12 between the two inboard girders 15.Main hoisting mechanism adopts planet three retarders to be the isosceles triangle layout, and two output shafts of planetary reduction gear 2 link by universal coupling and secondary retarder 9, and secondary retarder 9 links by drum coupling and reel 3.The electrical motor of main hoisting mechanism, coupler, drg 13, planetary reduction gear 2, secondary retarder 9, reel 3 are arranged on the top trolley frame 1, and fixed pulley group 4 is arranged on the bottom trolley frame 5, are positioned at the outside of two winding drum 3.Lifting mechanism can be used two motors, also available four electrical motors.Utilize the drive characteristic of planetary reduction gear double freedom, when the driving of a certain axle was lost efficacy in two input shafts of planetary reduction gear, by drg with this locking, another axle can steady in a long-term move, and the equal nonoverload of all mechanisms under real-time monitoring technique, 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 3 is equipped with sure brake 10 respectively, for the safe and reliable operation of complete machine is provided with further protection.
