Description
Technical field
The present invention relates to building machinery technical field, more particularly to a kind of low-noise concrete poker virbrator.
Background technology
During the concreting component mixed and stirred with concrete agitator, it is necessary to exclude wherein bubble, made firm by ramming, make to mix
Native closely knit combination is coagulated, the phenomenons such as the voids and pits of concrete are eliminated, to improve its intensity, it is ensured that the quality of concrete component.Shake
Dynamic rod is a kind of equipment of mechanization compacted concrete, during construction, and vibrating head is inserted in concrete, is excluded by its vibration mixed
Bubble in solidifying soil.Current concrete vibration bar is usually to produce vibration using motor driving tapper percussion vibration rod sleeve pipe,
So as to be vibrated to concrete, this vibrating head noise is very big, can have a strong impact on the normal life of resident near construction ground,
To have jeopardized the health of construction worker.
The content of the invention
The invention is intended to provide a kind of low-noise concrete poker virbrator without percussion, to solve concrete vibration bar noise mistake
Big the problem of.
Low-noise concrete poker virbrator, including motor, driving snake and sleeve pipe, the rotating shaft of the motor and the input of flexible axle
End connection, it is characterised in that flexible axle output end is fixedly connected with rotating shaft, the output end of the flexible axle and the drive end of the rotating shaft
It is fixedly connected, the rotating shaft connects the sleeve lining by bearing；It is cylindrical cavity inside the rotating shaft；In the cylindrical cavity
Provided with an eccentric heavy ball, the sphere diameter of the eccentric heavy ball is less than the radius of the cylindrical cavity；The cylindrical cavity bottom surface is
The sphere inwardly swelled.
Operation principle and beneficial effect：
Low-noise concrete poker virbrator is downwardly into concrete, and motor is rotated by driving snake drive shaft, rotating shaft
Interior eccentric heavy ball follows rotating shaft inwall to rotate together in the presence of frictional force；Because the diameter of eccentric heavy ball is less than inner chamber
Diameter, while rotating shaft inner chamber bottom surface is inwardly swelled spherical, heavy ball will not rest on the axis of rotating shaft under gravity
On, and rotate the centrifugal force produced and eccentric heavy ball is pressed on rotating shaft inwall, that is to say, that the center of gravity secundly of whole rotating shaft,
Then great centrifugal force is produced in high speed rotates, causes rotating shaft together with bearing and sleeve as a body vibration,
The effect of exciting is reached；Because rotating shaft and sleeve sleeve are linked together by bearing, each other without collision, greatly
Reduce noise.
Further, described eccentric weight ball surface is provided with rubber layer, increases its friction with rotating shaft inwall, and also it is buffered
Effect, reduces rotation beginning heavy ball at initial stage and collides the noise produced with rotating shaft inwall.
Further, the inwall of described rotating shaft is provided with rubber layer, increases the friction of its eccentric weight ball surface, and also it delays
Punching is acted on, and is reduced rotation beginning heavy ball at initial stage and is collided the noise produced with rotating shaft inwall.
Further, preceding two ends and centre are equidistant provided with three bearings in the sleeve so that the supporting of rotating shaft is more steady
It is fixed.
Further, described rotating shaft is thrust bearing, and thrust bearing can undertake bigger radial load, be difficult because
The vibration of rotating shaft and be destroyed.
Brief description of the drawings
Fig. 1 is the structural representation of embodiment of the present invention low-noise concrete poker virbrator；
Fig. 2 is the amplification at A in Fig. 1.
Embodiment
Below by embodiment, the present invention is further detailed explanation：
Reference in Figure of description includes：Motor 1, flexible axle 2, sleeve 3, rotating shaft 4, eccentric heavy ball 5.
Embodiment low-noise concrete poker virbrator is basic as shown in accompanying drawing 1, Fig. 2：
Low-noise concrete poker virbrator in this implementation, including motor 1, flexible axle 2, sleeve 3 and rotating shaft 4, the biography of motor 1
Moving axis is connected with the drive end of flexible axle 2, and the driven end of flexible axle 2 is fixedly connected with the drive end of rotating shaft 4, and rotating shaft 4 passes through left, center, right
Three promotion bearings are connected in sleeve 3 and coaxial with the sleeve 3；The inside of rotating shaft 4 is to be put in cylindrical cavity, cylindrical cavity
It is equipped with eccentric heavy ball 5；As shown in Fig. 2 being designed with rubber layer on the eccentric surface of heavy ball 5 and the inwall of rotating shaft 4, so both increase
Friction also reduces noise.
The course of work：
Low-noise concrete poker virbrator is downwardly into concrete, and motor 1 is revolved by flexible axle 2 with the rotating shaft 4 in moving sleeve 3
Turn, due to eccentric heavy ball 5 diameter be less than rotating shaft 4 cylindrical cavity diameter, while the cylindrical cavity bottom surface of rotating shaft 4 to
It is interior protuberance it is spherical, eccentric heavy ball 5 will not be rested on the axis of rotating shaft 4 under gravity, and rotate produce from
Mental and physical efforts are pressed in eccentric heavy ball on rotating shaft inwall, that is to say, that the center of gravity secundly of whole rotating shaft, then in high speed rotates
Great centrifugal force is produced, so that rotating shaft 4 is vibrated together with connected sleeve 3, so as to complete exciting.Because set
3 rotating shafts 4 of cylinder are linked together by bearing, can be considered do not relatively move to each other, also do not tap mutually, reached reduction
The effect of noise；And promote the bearing can to bear larger radial load, add the use longevity of low-noise concrete poker virbrator
Life.
Above-described is only that the known general knowledge such as concrete structure and characteristic is not made herein in embodiments of the invention, scheme
Excessive description., can be with the premise of structure of the present invention is not departed from it should be pointed out that for a person skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these are implemented all without the influence present invention
Effect and practical applicability.This application claims protection domain should be defined by the content of its claim, in specification
Embodiment etc. records the content that can be used for explaining claim.
