Technical Field

The invention relates to the technology of mechanical equipment, in particular to a buffering power-assisted speed reducing device of a material taking machine.

Background

The material reclaimer is mainly used for the reclaiming operation of iron ore concentrate in stockyards such as electric power, metallurgy, harbors and the like, and is a large-scale reclaiming device for conveying iron ore concentrate and uniformly mixing mineral materials, which is manufactured at home. The rake mechanism of the material reclaimer has the function that the rake rakes the surface of a mineral material pile through reciprocating linear motion, and the rake teeth are used for raking the surface of the mineral material pile to achieve the purpose of pile loosening, so that materials on the cross section of the material pile smoothly slide to the bottom of the material pile and are taken away by a material taking hopper to be conveyed to a belt conveyor to be conveyed to a next procedure. Whether the material taking machine operates normally or not is related to the completion of sintering production and iron-making tasks. In recent years, due to the fact that the environment of a bulk material yard is severe, the physical properties of bulk materials are greatly different, equipment operates in the open air, the problems that the operation of the equipment is influenced in the long-term use process of a material reclaimer occur, the fault is continuous, the development of production is severely restricted, and the arrangement mode of rake driving components has defects.

When a rake driving member of the material reclaimer moves in a reciprocating manner and reverses, the rake driving member meets traveling resistance to form huge impact load, an open gear is directly arranged on an output shaft of a speed reducer, an output driving shaft is fixed to be of a hyperstatic structure, the open gear has large transmission impact load, the speed reducer bears abnormal vibration load, and a base of the speed reducer is frequently torn; the vibration of the reducer causes the entire mounting platform of the reducer and the motor to vibrate. Because the speed reducer is fixed on a platform articulated with the basis, consequently speed reducer mounting platform also vibrates thereupon and assaults greatly, and the platform tears the condition and takes place occasionally. Because the drive open gear is directly arranged on the output shaft of the speed reducer, the speed reducer has alternating load, and the impact vibration is transmitted to the speed reducer to enable the impact between the speed reducer and the crankshaft bearing seat to be enlarged, so that the accidents of explosion of a shell of the speed reducer and broken shaft and teeth of the speed reducer are caused, and even the accidents of tilting of a driving device of the speed reducer and the like occur. The fatigue damage of an open gear arranged on an output shaft of the speed reducer is caused due to the action of larger alternating stress in the mechanism; welding a base of a material rake bearing seat in a blasting way, and breaking a foundation bolt of the bearing seat; box girder tears, etc., which become production-restricting bottlenecks.

Drawings

The invention will be further described with reference to the accompanying drawings and examples, in which:

FIG. 1 is a schematic structural diagram of an embodiment of the present invention;

in the figure: the material rake device comprises a motor 1, a coupler 2, a speed reducer 3, an open gear 4, a duplex bearing seat 5, a crank 6 and a rake trolley 7.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, a buffering power-assisted speed reducer of a material reclaimer comprises: the device comprises a motor 1, a coupler 2, a speed reducer 3, a tooth type coupler, an open gear 4 and a gear shaft;

the motor 1 is connected with a speed reducer 3 through a coupler 2, one end of a gear coupling is connected with an output shaft of the speed reducer, the other end of the gear coupling is connected with a gear shaft, an open gear 4 is installed on a gear shaft, the open gear comprises a driving open gear and a driven open gear, and the driven open gear is meshed with the driving open gear; the gear shaft of the driven open gear is provided with a crank 7, and the circular motion output by the speed reducer is converted into the reciprocating linear motion of the material rake trolley through a crank sliding block mechanism, so that the rake teeth on the trolley reciprocate on the material taking surface to achieve the purpose of loosening.

And a flange gasket uniformly distributed with the speed reducer is welded and installed on the base of the speed reducer. Even drilling on the flange dish washer, the packing ring welding is on the base of speed reducer, and flange dish washer and speed reducer base are even as an organic whole, and when the base height increased, the screw thread of the stud of installation has also lengthened, and bolt screw thread increases like this, even the speed reducer impact force is big, the not hard up frequency of rag bolt also very reduces, weekly to bolt inspection once can. After the speed reducer frame is raised, the corresponding motor frame is also raised, and the coaxiality is kept consistent.

The gear coupling is additionally arranged on the output shaft of the speed reducer and has the advantages of high transmission efficiency, impact resistance, no noise, long maintenance period and high bearing capacity. The newly-added tooth type coupler avoids the direct installation of the open gear on the output shaft of the speed reducer, and has the advantage of avoiding the influence of alternating load on the speed reducer, and the vibration of the speed reducer is overlarge due to the alternating load existing in the reaction force when the open gear is meshed. The newly added tooth type coupling reduces the impact on the speed reducer when the speed reducer is reversed. The output shaft of the speed reducer does not bear radial force and only transmits torque, so that the problems of large vibration and left-right shaking of the speed reducer caused by poor positioning are solved. Not only the speed reducer is protected, but also the motor and the coupler are protected from being broken and damaged. The output of the speed reducer and the transmission shaft of the open gear are free from adopting a statically indeterminate structure, and a coupler flexible connection is added between the output shaft of the speed reducer and the transmission shaft so as to reduce the impact load and the influence of vibration on the speed reducer caused by open gear transmission.

And a gear shaft is additionally arranged at the other end of the gear coupling, and a driving open gear is arranged on the gear shaft. The driven open gear is meshed with the driving open gear arranged on the gear shaft, and 2 supporting double-linked bearing seats are arranged on the gear shaft of the driven open gear. The duplex bearing seat, the gear shaft and the speed reducer flange washer form a frame structure, so that the shock resistance is enhanced, and the problems of looseness of bolts of the crankshaft bearing seat and tearing of a box girder bottom plate are solved; the problems of severe abrasion and high maintenance frequency of the open gear are avoided; the motor of the speed reducer is protected, and the speed reducer is prevented from tipping. Because the stress form is changed, the impact force is transferred from the speed reducer to the pair of open gears, and the transmission devices such as the speed reducer, the motor and the like are protected in a buffering way. The 2 duplex bearing seats play a role in bearing the tilting moment of the motor of the speed reducer, and the impact generated during reversing is borne by the duplex bearing seats.

The installation of the gear coupling, the duplex bearing seat and other buffering power assisting devices also reduces the impact force caused by the walking resistance when the crank and the connecting rod are in the horizontal position.

The above structure achieves the effect of buffering assistance of the speed reducing device.

It will be understood that modifications and variations can be made by persons skilled in the art in light of the above teachings and all such modifications and variations are intended to be included within the scope of the invention as defined in the appended claims.
