Description
Technical field
The utility model relates to a kind of Transport Machinery equipment technical field, and specifically, what relate to is a kind of metallurgical bridge crane hoisting mechanism.
Background technology
Crane in bridge type is a kind of crane span structure type hoisting crane that crane span structure moves on aerial conveyor, claims overhead traveling crane again.The crane span structure of crane in bridge type vertically moves along being laid on the track of both sides on overhead, crane carriage laterally moves along the track that is laid on the crane span structure, constitute the operating range of a rectangle, just can make full use of the space handling material below the crane span structure, be not subjected to the obstruction of wayside equipment.Crane in bridge type generally is made up of crane carriage, crane span structure operating unit, crane span structure metal construction.Crane carriage is made up of lifting mechanism, wheeling mechanism and trolley frame three parts again.
The radical function of lifting mechanism is a hoisting heavy, in frequent lifting, unloading and speed-change process, the parts of each link of lifting mechanism all are in the bigger reverse stress state, can cause its damage because of reasons such as fatigues, in case damage parts, whole drive system was lost efficacy, and its consequence will make the unexpected tenesmus out of control of the skyborne weight of handling, causes sudden accident.The quality of lifting mechanism serviceability is one of important symbol of weighing the conveyer performance.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, and a kind of metallurgical bridge crane hoisting mechanism is provided, and is simple in structure, can improve traveling comfort, thereby improves the in-use performance of complete machine.
For realizing above-mentioned purpose, metallurgical bridge crane hoisting mechanism described in the utility model comprises retarder, drg, coupler, reel, dead sheave, compensating shaft, electrical motor, bearing seat and rising mechanism limiting device.Retarder one end is provided with drg, and the retarder high speed shaft is connected to an end of coupler, and the coupler other end connects an end of compensating shaft, and the other end of compensating shaft is connected to electrical motor.The retarder slow-speed shaft connects an end of reel, and the other end of reel is supported on the bearing seat, and the opposite side of bearing seat is provided with rising mechanism limiting device.Dead sheave is arranged on the top of reel.
Further, described electrical motor is the YZR wound-rotor motor.
Further, described coupler is a gear coupling.The employing gear coupling connects, even the error that is produced when making and install perhaps because the caused crane span structure of load is out of shape the displacement each other between the parts that produce, also can be compensated the unlikely work that influences mechanism by gear coupling.
Further, described retarder is the involute teeth wheel decelerator.
Further, be wound with steel rope on the described reel.
The utility model is simple in structure, is provided with rationally, and two cover lifting mechanisms can move synchronously or asynchronously, easy access, and work is by property, and safety performance is good, has improved the in-use performance of complete machine, can be widely used in metallurgy hopper bridge crane.
Description of drawings
Fig. 1 is a kind of structural representation in the utility model specific embodiment;
Among the figure: retarder 1, drg 2, coupler 3, reel 4, dead sheave 5, compensating shaft 6, electrical motor 7, bearing seat 8, rise mechanism's limiting device 9.
The specific embodiment
Below in conjunction with drawings and Examples the technical solution of the utility model is further explained, but following content is not used in qualification protection domain of the present utility model.
As shown in Figure 1, present embodiment provides a kind of metallurgical bridge crane hoisting mechanism, comprises retarder 1, drg 2, coupler 3, reel 4, dead sheave 5, compensating shaft 6, electrical motor 7, bearing seat 8 and rising mechanism limiting device 9.Retarder 1 high speed shaft one end is provided with drg 2, and the retarder 1 high speed shaft other end is connected to an end of coupler 3, and coupler 3 other ends connect an end of compensating shaft 6, and the other end of compensating shaft 6 is connected to electrical motor 7.Retarder 1 slow-speed shaft connects an end of reel 4, and the other end of reel 4 is supported on the bearing seat 8, and the opposite side of bearing seat 8 is provided with rising mechanism limiting device 9.Dead sheave 5 is arranged on the top of reel 4.
Further, described electrical motor 7 is a YZR wound-rotor motor 7.
Further, described coupler 3 is a gear coupling 3.The error that is produced when making and install adopt gear coupling 3 to connect, even perhaps because the caused crane span structure of load is out of shape the displacement each other between the parts that produce, also can be compensated the unlikely work that influences mechanism by gear coupling 3.
Further, described retarder 1 is an involute teeth wheel decelerator 1.
Further, be wound with steel rope on the described reel 4.
Lifting mechanism in the present embodiment has two covers, is installed in the top of trolley frame respectively, and two cover lifting mechanisms are individual drive separately.Lifting mechanism drives involute teeth wheel decelerator 1 by the high speed revolution of YZR wound-rotor motor 7 through gear coupling 3, and the slow-speed shaft of retarder 1 rotates the reel 4 that is wound with steel rope again, steel rope is put down, with the lifting material around coiling 4 or from reel 4.Need only the rotating at control motor 7, just can reach the lift action of suspension hook.
For safety and the reliability that guarantees lifting mechanism work, on retarder 1 high speed shaft, drg 2 is housed.On the bearing of supporting drum 4 one ends rising limiting device 9 being housed, is the safety device of suspender when rising to end position.
As can be seen from the above embodiments, the utility model is simple in structure, be provided with rationally, and easy access, work is by property, and safety performance is good, has improved the in-use performance of complete machine.
