Abstract
The utility model relates to a lifting mechanism for a crane, in particular to a lifting mechanism for realizing lifting of goods, which is an important mechanism of the crane. A motor thereof is coupled with the high-speed end of a speed reducer by a gear coupling with a brake wheel; a brake is arranged on a shaft of the speed reducer by a coupling with a brake wheel, and is interlocked with the power of the motor; a winding drum is coupled with the low-speed end of the speed reducer by a gear coupling of the winding drum and is arranged on a rotating shaft; the shaft end of the winding drum is arranged in a bearing of a bearing seat; and one end of a steel wire rope is wound on the winding drum, and the other end thereof is coupled with a lifting hook group, thus controlling the lifting hook by realizing the lifting hook group by adjusting the motor to realize lifting and falling. The lifting mechanism has simple, compact and reasonable structure; since the lifting mechanism is coupled by the gear coupling with compensation performance, the installation is convenient; and the work is safe and reliable, and the production efficiency can be improved.
Description
Technical field
The utility model relates to a kind of lifting mechanism that is used for hoisting crane, specifically is used for realizing lifting of goods, is important mechanism in the hoisting crane.
Background technology
At present, in the span winch working process, often use the lifting mechanism device of a lot of types, some constructional device that hoists exists manufacture difficulty big, assembling difficulty etc., and so both waste of manpower and financial resources greatly reduced work efficiency again.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of safe and reliable, makes simply, is convenient to M R, the lifting mechanism of the hoisting crane that can enhance productivity.
The technical scheme that provides according to the utility model, the lifting mechanism of hoisting crane comprises electrical motor, the gear coupling of band brake wheel, drg, retarder, the reel gear coupler, reel, steel rope, the suspension hook group, bearing seat, electrical motor connects with the gear coupling that the speed end of retarder is taken turns by band brake, drg is installed on the reducer shaft by the coupler of band brake wheel, the electric interlocking of drg and electrical motor, reel connects by the reel gear coupler with the low speed end of retarder, reel is contained in the rotating shaft, the axle head of reel then is loaded in the bearing in the bearing seat, steel rope one end is wrapped on the reel, the other end connects with the suspension hook group, thereby controls suspension hook group realization rising or decline by regulating electrical motor.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because this lifting mechanism connects by the gear coupling that compensation performance is arranged, be convenient to install; Safe and reliable, can enhance productivity.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, the lifting mechanism that is used for hoisting crane described in the utility model comprises gear coupling 2, drg 3, retarder 4, reel gear coupler 5, reel 6, steel rope 7, suspension hook group 8, bearing seat 9 that electrical motor 1, band brake are taken turns.
The utility model is to be driven by electrical motor 1.The gear coupling 2 that electrical motor 1 is taken turns by band brake by the coupler and the high speed axle head of retarder 4 connects, during work, the slow-speed shaft of retarder 4 drives reel 6, steel rope 7 volumes are gone up or emitted, through pulley block system 10, make suspension hook group 8 realize rising or descending, when mechanism quits work, drg 3 makes suspension hook be suspended in the air together with goods, and the lifting of suspension hook group 8 is leaned on electrical motor 1 to change to turn to and realized.
The utility model adopts the gear coupling 2 that has compensation performance, to arrange more convenient and increase compensation ability, reduce wearing and tearing in order to make, often gear coupling 2 is made two and half gear couplings, the centre has one section axle to link up, and this section axle is called floating axle or compensating shaft.
The coupler of drg 3 band brakes of the present utility model wheel is installed on 4 of the retarders, to reduce its size, often utilize a halfbody used as braking wheel of coupler, the coupler halfbody of band brake wheel should be installed on the reducer shaft, like this, even coupler damages, drg still can work, and has guaranteed safety.Sometimes need to install two drgs on high speed shaft, then second drg can be installed in the high-revolving other end of retarder.
Drg 3 of the present utility model should be a normally closed.Block brake commonly used is equipped with electromagnet or electric pushrod as the device that declutches automatically, the electric interlocking of drg 3 and electrical motor 1, and the brake braking force square guarantees to have enough brake safe coefficients.
Retarder 4 enclosed cylinder gear speed reducers commonly used of the present utility model.
Reel 6 of the present utility model connects by reel gear coupler 5 with the low speed end of retarder 4, and reel 6 is contained in the rotating shaft usually, makes the inspection of bearing all more convenient with replacing.Reel 6 can be connected by cog-wheel coupling 2 with retarder 4 slow-speed shafts.6 on reel is supported in the bearing seat 9 with bearing, and torque is connected by profile of tooth transmits.This method compactness, reliable, grouping property number can compensate the interaxle angular deviation of reducer shaft and reel.Steel rope 7 one ends are wrapped on the reel 6, and the other end connects with suspension hook group 8, thereby control 8 realization rising or the declines of suspension hook group by regulating electrical motor 1.
