Description
Technical field
The utility model relates to Large Efficient continuous handling facilities bucket-wheel stacker reclaimer fields, are specifically related to a kind of bucket
Take turns speed reducer anti-drop device, be widely used in large-scale bulk cargo port, the coal yard in thermal power plant, large-scale steel mill ore coal
The storing place of the departments such as carbon feedstock field, Cement Plant.
Background technique
Bucket-wheel stacker reclaimer is a kind of continuous handling facilities of Large Efficient, has heap reclaiming capacity big, takes up little area operation
The features such as convenient.Bucket-wheel mechanism is arranged in bucket-wheel stacker reclaimer cantilever front.The driving device of bucket-wheel mechanism includes motor, coupling
Device, retarder, bucket wheel axle etc..In the bucket wheel driving device of stacker-reclaimer, the driving device of bucket-wheel mechanism uses machine driving
Mode, motor driven speed reducer drive bucket wheel to rotate feeding；Bucket wheel axle generally uses spline to couple with coupling for retarder.Spline
Connection is that multi-gear works, and has many advantages, such as that bearing capacity is high, centering is good, guiding performance is good, stress collection is medium and small；Current general import
In the design structure of the spline connection of speed reducer, output shaft is hollow hub splines, and both ends are respectively equipped with processing transition face and bucket
The concentric transition fit of wheel shaft is sleeved on the end of bucket wheel axle, and two half-sectional ring flanges are placed in groove, passes through bolt and spline
For set locking is closed, entire driving device is fixed on the gravity of drive system on bucket wheel axle by spline housing and two half-sectional positioning plates
To bear.
Domestic many power plant's stockpiling in stock ground scenes use automobile coal piling at present, part dump after cart repeatedly rolls,
For hardness comparable to asphalt surface, bucket-wheel stacker reclaimer is to take bulk material to design according to technical protocol, can not be made as excavator
With；So it is uneven to excavate material during taking such material.Bucket-wheel mechanism necessarily overloads, and is carried by biggish impact
Lotus.
It is all kinds of unstable in the moment of flexure and material extracting operation that spline housing still suffers from drive system other than bearing torque
Load and amplitude, positioning plate stress is larger, and size for connection is too short.Bucket wheel body is during rotating feeding by biggish impact
Load and vibration cause hollow sleeve to be born excessive around dynamic loading, and ovalizing deflection occurs for hollow sleeve, and junction is constantly to opposite
Opposite micro-displacement occurs for weak ring flange, and original reasonable flange bolt has received continuous impact.With the passage of time not
Disconnected accumulation leads to ring flange deformation failure, and bolt is cut, until speed reducer falls off.
Summary of the invention
In view of domestic industry specific special stock ground situation, for around dynamic loading it is excessive, the utility model provides one kind
Bucket wheel reducer anti-drop device can make bucket wheel body carry biggish load and amplitude during rotating feeding, avoid
Due to the problem of ovalizing deflection occurs for hollow sleeve, speed reducer falls off caused by ring flange deformation failure.
To achieve the goals above, the technical scheme adopted by the utility model is a kind of bucket wheel reducer anti-dropout fills
It sets, including bucket wheel output shaft, is sleeved on the hollow spline housing of bucket wheel output shaft end, hollow spline housing outer radial position setting is embraced
Hoop, anchor ear one end are equipped with ring flange close to hollow spline housing, the anchor ear other side, and anchor ear is fastened by bolts with ring flange；
Further, positioning annulus is additionally provided between anchor ear and ring flange, positioning annulus passes through bolt for hollow spline housing
It is fastened on bucket wheel output shaft；
The anchor ear is split type split setting；
The ring flange is split type structure；
The anchor ear thickness is not less than the 2/3 of hollow spline housing thickness, and high-strength bolt group is held tightly, made by anchor ear hollow
Spline housing bears bigger around dynamic loading and bounce；
The flange thickness of bucket wheel side is not less than spline housing thickness, so that hollow spline housing is born by ring flange more curved
Square.
The utility model is to offset or reduce the ovalizing deflection of hollow spline housing by thickening output shaft wall thickness, can be made
Bucket wheel body carries biggish load and amplitude during rotating feeding, and the output shaft of thickening compares original output not thickeied
Axis can big load moving, avoiding impacting ring flange leads to deformation failure and speed reducer is made to fall off.
Detailed description of the invention
The structure chart of Fig. 1 the utility model.
Fig. 2 is the side view of Fig. 1.
In figure, 1, anchor ear 2, ring flange 3, bucket wheel output shaft, 4, hollow spline housing, 5, bolt, 6, hexagon socket head cap screw, 7, it is fixed
Circle of position ring.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
A kind of bucket wheel reducer anti-drop device including bucket wheel output shaft 3, is sleeved on the hollow of 3 end of bucket wheel output shaft
Anchor ear 1 is arranged in spline housing 4, hollow 4 outer radial position of spline housing, and 1 one end of anchor ear is set close to hollow spline housing 4,4 other side of anchor ear
There is ring flange 2, anchor ear 1 is fastened with ring flange 2 by bolt 5；
Further, positioning annulus 7 is additionally provided between anchor ear 1 and ring flange 2, positioning annulus 7 passes through bolt for treasure maesa herb
Key set 4 is fastened on bucket wheel output shaft 3；
The anchor ear 1 is split type split setting；
The ring flange 2 is split type structure；
The utility model is offset by thickening output shaft wall thickness or reduces hollow 4 ovalizing deflection of spline housing: first herein
Hollow 4 outer diameter of spline housing adds split anchor ear 1 after doing polishing blasting treatment, and 1 thickness of anchor ear is not less than hollow 4 thickness 2/3 of spline housing,
High-strength bolt group 5 is held tightly, bears hollow spline housing 4 by anchor ear 1 bigger around dynamic loading and bounce, screw-down torque is spiral shell
2 thickness of ring flange of the 2/3 of bolt rated moment, bucket wheel side is not less than hollow 4 thickness of spline housing, makes treasure maesa herb by ring flange 2
Key set 4 can bear more moments of flexure, anchor ear 1 and the intermediate stationary positioned annulus 7 of ring flange 2, and make treasure maesa herb by multiple groups bolt group
Key set 4 is tightly secured on bucket wheel output shaft 3, finally makes torque.
The utility model is applied to the Jining Inner Mongol Jing Neng thermoelectricity 2 × 350MW thermal power plant unit engineering and is equipped with two
DQL1550/155035 type bucket-wheel stacker reclaimer.
