The hoisting mechanism is more safe and reliable, thereby thoroughly eliminating the safety hazards of the hoisting mechanism of the planet three-grade reducer of the casting crane.
Description
Technical field
The utility model relates to elevator machinery, the isosceles triangle planetary reducer lifting mechanism that particularly a kind of ladle carne uses.
Background technology
Isosceles triangle planetary reducer (first class reducer, two 2-level reducers) lifting mechanism, on ladle carne, use very wide, arrangement form that it is general such as accompanying drawing 1.Mainly form by sure brake 1, reel 2,2-level reducer 3, electrical motor 4, one-level coupler 5, planetary reducer 6, top sheave device 7, secondary coupler 8, high speed shaft drg 9.Electrical motor 4 links to each other with planetary reducer 6 by one-level coupler 5,2-level reducer 3 links to each other with planetary reducer 6 by secondary coupler 8, reel 2 links to each other with 2-level reducer 3 slow-speed shafts, top sheave device 7 is arranged in reel 2 next doors, by the steel rope winding reel and suspender are coupled together, carry out carrying heavy goods (being generally fully loaded steel ladle), high speed shaft drg 9 is installed on the high speed shaft of planetary reducer 6, sure brake 1 is installed on the reel 2.
Reductor and brake system thereof are the cores of this transmission scheme, i.e. a planetary reducer 6 (first class reducer), two 2-level reducers 3, high speed shaft drg 9, sure brake 1.Planetary reducer 6, one-level coupler 5 and secondary coupler 8 are relative weak links in this transmission scheme, after if the planet bag of planetary reducer 6 or one-level coupler 5 damage, high speed shaft drg 9 and sure brake 1 can generally can not have an accident according to the sequencing band-type brake of setting under the normal circumstances.After but if secondary coupler 8 damages, high speed shaft drg 9 is inoperative fully, can only lean on sure brake 1 this last line of defense, and reality is, sure brake system itself constitutes complicated, especially fault detection system, usually because mechanical setting accuracy, detection coder even software factor make the sure brake system in time not move when et out of order, and often appear at sure brake misoperation under the nominal situation, even some user can throw off the sure brake system because of the sure brake misoperation.Thus, if when secondary coupler 8 lost efficacy, it is insecure only relying on sure brake 1.Prior art ladle carne planet three reductor lifting mechanisms exist potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of safer failure-free ladle carne planet three reductor lifting mechanisms are provided.
The technical solution of the utility model is achieved in that
A kind of ladle carne planet three reductor lifting mechanisms, comprise: sure brake 1, reel 2,2-level reducer 3, electrical motor 4, one-level coupler 5, planetary reducer 6, top sheave device 7, secondary coupler 8, high speed shaft drg 9, two electrical motors 4 link to each other with planetary reducer 6 by one-level coupler 5 respectively, two 2-level reducers 3 link to each other with planetary reducer 6 by secondary coupler 8 respectively, two reels 2 link to each other with two 2-level reducer 3 slow-speed shafts respectively, two top sheave devices 7 are arranged in reel 2 next doors, by the steel rope winding reel and suspender are coupled together, be separately installed with high speed shaft drg 9 on two high speed shafts of planetary reducer 6, be separately installed with sure brake 1 on two reels 2, it is characterized in that: drg 10 has been installed respectively on the high speed shaft of described two 2-level reducers 3.
The utility model is compared with the isosceles triangle planetary reducer lifting mechanism of routine, many drgs that are installed on the 2-level reducer high speed shaft, under the nominal situation, drg 10 on high speed shaft drg 9, the 2-level reducer and sure brake 1 carry out band-type brake sequentially.On this messenger chain, the wear pattern of external toothing and internal tooth casing is difficult for checking in one-level coupler 5 and the secondary coupler 8, its degree of wear is not understood, after use after a while, sudden failure may take place, if after the secondary coupler between the 2-level reducer 8 lost efficacy, being installed in that drg on 3 of the 2-level reducers will move should the locking of deceleration arbor, even sure brake 1 is action not, can not slip the hook accident yet.Therefore, on 2-level reducer 3 high speed shafts drg 10 has been installed, to planetary reducer lifting mechanism messenger chain many one heavily protect link, make it more safe and reliable, thoroughly eliminated the potential safety hazard that ladle carne planet three reductor lifting mechanisms exist.

Fig. 1 is the structural representation of the isosceles triangle planetary reducer lifting mechanism of prior art;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is elaborated by preferred embodiment below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of ladle carne planet three reductor lifting mechanisms, comprise: sure brake 1, reel 2,2-level reducer 3, electrical motor 4, one-level coupler 5, planetary reducer 6, top sheave device 7, secondary coupler 8, high speed shaft drg 9, two electrical motors 4 link to each other with planetary reducer 6 by one-level coupler 5 respectively, two 2-level reducers 3 link to each other with planetary reducer 6 by secondary coupler 8 respectively, two reels 2 link to each other with two 2-level reducer 3 slow-speed shafts respectively, two top sheave devices 7 are arranged in reel 2 next doors, by the steel rope winding reel and suspender are coupled together, be separately installed with high speed shaft drg 9 on two high speed shafts of planetary reducer 6, be separately installed with sure brake 1 on the transmission shaft of two reels 2, it is characterized in that: drg 10 has been installed respectively on the high speed shaft of described two 2-level reducers 3.
