Description

Special lifting speed reducer for steel plant

Technical Field

The utility model relates to a verifying attachment, especially a special speed reducer that plays to rise of steel mill.

Background

The steel industry can strictly control the total capacity, accelerate elimination of the backward capacity and strictly control the newly increased capacity. After a long-term extensive expansion of the steel industry, there is a need to accelerate structural adjustments and industry upgrades that present challenges to the metallurgical heavy machinery manufacturing industry, particularly the high-end equipment manufacturing industry with high technology content.

The service life of the travelling crane trolley of the steel plant is long at present, the lifting mechanism on the travelling crane trolley adopts a high-speed connection mode, the lifting mechanism on the travelling crane trolley lifts heavy objects at high speed for a long time, so that a steel wire rope and a balance beam of the device are seriously deformed, once one device in the lifting mechanism breaks down, the heavy objects carried by a hook body of the lifting mechanism fall on the ground, other devices are easily damaged, and workers on the site can be seriously injured.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is not enough to above-mentioned prior art, and provide a special decelerator that plays to rise of steel mill, this special decelerator that plays to rise of steel mill utilizes two sets of identical lifting unit, the lift of simultaneous control coupler body, can be more accurate collude the thing of carrying, and when one of them a set of lifting unit broke down, can control the coupler body in another a set of lifting unit short time and the heavy object of colluding can not be quick pound to ground, cause the damage of other equipment, perhaps pound the staff on the scene of hindering.

In order to solve the technical problem, the utility model discloses a technical scheme is:

a lifting speed reducer special for a steel plant comprises a balance beam, two groups of identical lifting components and a hook body; one of them group lifting unit includes driving motor, speed reducer, reel, wire rope and rope sheave, through coupling joint between driving motor and the speed reducer, through spherical hinge shape coupling joint between speed reducer and the reel, the cover is around wire rope between reel and the rope sheave, the equal fixed mounting of driving motor, speed reducer and reel among the lifting unit is on the compensating beam, has the hole that lets wire rope pass on the compensating beam, and wire rope between reel and the rope sheave runs through the compensating beam, and the rope sheave is located the compensating beam below, and the terminal fixed connection of wire rope on the rope sheave is on the coupler body.

Furthermore, the driving motor is connected with the speed reducer through a ball coupling.

Furthermore, the speed reducer is connected with the winding drum by a WZL spherical hinge-shaped coupling.

Furthermore, the winding drums in the two groups of lifting assemblies are connected through universal couplings.

The utility model discloses following beneficial effect has: utilize two sets of identical lifting unit, the lift of simultaneous control coupler body can be more accurate collude and carry the thing to the equipment of major office all independently fixes on the compensating beam, when any equipment breaks down, need not dismantle the equipment that other equipment just can maintain the damage, makes the maintenance of equipment more convenient, the utility model discloses simple structure, operation easy maintenance designs the environmental protection, is convenient for extensively promote.

Drawings

FIG. 1 is a schematic structural view of the lifting speed reducer specially used in steel works.

Among them are: 1-1, driving a motor a; 1-2, driving a motor b; 2-1, a speed reducer a; 2-2, a speed reducer b; 3-1, reel a; 3-2. drum b; 4. a balance beam; 5-1, a rope wheel a; 5-2, rope wheel b; 6. a hook body.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

In the description of the present invention, it should be understood that the terms "left side", "right side", "upper part", "lower part" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, "first", "second" and the like do not indicate the degree of importance of the component parts, and thus, are not to be construed as limiting the present invention. The specific dimensions used in the present embodiment are only for illustrating the technical solution, and do not limit the protection scope of the present invention.

As shown in figure 1, a lifting speed reducer special for steel plants comprises a balance beam 4, two groups of identical lifting components and a hook body 6, wherein one group of lifting components comprises a driving motor a1-1, a speed reducer a2-1, a winding drum a3-1, a steel wire rope and a rope pulley a5-1, the driving motor a1-1 and the speed reducer a2-1 are connected by adopting a ball coupling, other inelastic element flexible couplings can be used for connecting the driving motor and the speed reducer, the speed reducer a2-1 and the winding drum a3-1 are connected by a ball hinge coupling, in the embodiment, a specially selected WZL ball hinge coupling is connected with the speed reducer and the winding drum, the driving motor a1-1, the speed reducer a2-1 and the winding drum a3-1 are respectively and fixedly arranged on the balance beam 4, the steel wire rope is wound between the winding drum a3-1 and the rope pulley a5-1, the balance beam is also provided with a hole for the steel wire rope to pass through, after the steel wire rope between the reel a3-1 and the rope pulley a5-1 passes through the balance beam 4, the rope pulley a5-1 falls below the balance beam 4, and the tail end of the steel wire rope on the rope pulley a5-1 is fixedly connected to the hook body 6; in order to keep the hook body 6 balanced, a universal coupling connection is provided between the reel a3-1 and the reel b 3-2.

Utilize two sets of identical lifting unit, the lift of simultaneous control coupler body, can be more accurate collude the year thing, and when one of them a set of lifting unit broke down, another group lifting unit can temporarily keep the heavy object on coupler body and the coupler body can not drop rapidly, cause the damage of equipment and injure the occurence of failure of field personnel, and during the equipment of maintenance damage, need not dismantle other equipment just can maintain the equipment of damage, make the maintenance process more simple and convenient, the maintenance time is saved, the production loss is reduced, and the work efficiency is improved.
