Description
Technical field
The utility model relates to the lifting mechanism that quenches with hoisting crane, and the normal speed that is specially adapted to quenching crane promotes and a kind of the quenching with the addition lifting mechanism of hoisting crane that descends fast.
Background technology
In the metal heat treatment industry, when workpiece need quench, require the lifting mechanism of the hoisting crane of handling workpiece will possess the function of quick decline; What at present, the lifting mechanism of traditional quenching crane all adopted is the structure that the main electrical motor that hoists adds tacking motor; When the quenching operation needs lifting mechanism to descend fast, open the drg on the main motor reel that hoists earlier, lifting mechanism is high-speed cruising under the load gravity drive, tacking motor sends signal when running velocity is too fast, drg on the closed main motor reel that hoists reduces the running velocity of lifting mechanism.Above-mentioned action is carried out repeatedly in whole quenching operation process, drg repeated open, closure on the promptly main motor reel that hoists.Such lifting mechanism has two defectives: the one, and be single input shaft, and brake wear is too fast, in case break down, both unfavorable to load safety, influence is produced again; The 2nd, there is the hypervelocity phenomenon in the main electrical motor that hoists, and is also unfavorable to load safety.
Summary of the invention
The utility model is intended to the defective and the weak point that exist in above-mentioned technology, not only can descend fast can slow running and provide, and make lifting mechanism have safe in operation, reliable, a kind of quenching energy-conservation, easy to use with the addition lifting mechanism of hoisting crane.
The purpose of this utility model realizes with following technical scheme: a kind of quenching with the addition lifting mechanism of hoisting crane, comprise motor, drg, reel group, it is characterized in that: between the two winding drum group, put planetary reduction gear, the two ends of the output shaft of planetary reduction gear are joined with a reel group respectively, on an input shaft of planetary reduction gear, connect a first motor or two first motors, relative with the first motor, on another input shaft of planetary reduction gear, connect a second motor or two second motors, adorn drg respectively on each first, second motor shaft.It mainly is made up of the lifting mechanism of described addition principle first motor, second motor, drg, planetary reduction gear and reel group, described first, the second motor of on the planet input shaft of speed reducer, being adorned, can be according to the design needs, the mode of the relative arranged of its first, second motor can be divided into two electric motor types, three electric motor types, four electric motor types; Described two electric motor types: be on an input shaft of planetary reduction gear, to connect a first motor, connect a second motor on another input shaft of planetary reduction gear; Described three electric motor types: described three electric motor types: the two ends symmetry on an input shaft of planetary reduction gear connects a kind of same motor, and the end on another input shaft of planetary reduction gear connects an another kind of motor; Described four electric motor types: the two ends symmetry on an input shaft of planetary reduction gear connects the first motor, and the two ends symmetry on another input shaft of planetary reduction gear connects a second motor.It is to be core with the planetary reduction gear for the lifting mechanism of described addition principle, adopts the planetary reduction gear of addition principle, and the input speed of two input shafts of planetary reduction gear is at the superposition at pinion carrier place, so be called the lifting mechanism of addition principle.
Its principle of work and process are in down: be subjected to the characteristic of the double freedom of planetary reduction gear own to determine the independence of two input.This characteristic is applied on the crane hoisting mechanism, and when the motor on two input shafts was worked simultaneously, lifting mechanism ran at high speed; When motor on the high speed shaft of planetary reduction gear or the damage of its control system, this lock is lived, but the motor long-time running on another, the equal nonoverload in any position in the mechanism, when the quenching operation, the motor of two input shafts is worked simultaneously, satisfies quick decline operating mode; When carrying out other general lifting jobs, the machine operation of an input shaft in two input shafts, the motor of another input shaft cuts out, and satisfies general lifting operating mode, reaches energy saving purposes.Under above two kinds of operating modes, the motor on two input shafts is all with the command speed operation, and therefore the phenomenon that do not exceed the speed limit can guarantee that load descends safely fast; The effect that this characteristic produces is that lifting mechanism can at high speed and two kinds of speed operations of low speed, and simultaneously for lifting mechanism, fiduciary level has improved widely, because the probability that two cover input shafts damage simultaneously is lower than the probability that single input shaft damages; The addition lifting mechanism that is used for quenching crane adopts the planetary reduction gear of addition principle, form two relatively independent cover mechanisms, the normal speed that satisfies quenching crane promotes and the special operation requirement of decline fast, solved quenching crane and descended safely and fast, the power saving during non-quenching operation.The vertical above technical measures of being taked realize purpose of the present invention.
Advantages such as compared with prior art, the utility model is not only rational in infrastructure, can descend fast and can slow running, and make lifting mechanism have safe in operation, reliable, and is energy-conservation, easy to use.
