Abstract
The application discloses a low -noise concrete poker virbrator, including motor, flexible axle and sleeve, the transmission shaft of motor is connected with the drive end of flexible axle, still is equipped with the pivot, the driven end of flexible axle with the drive end fixed connection of pivot, this pivot is still connected through the bearing the sleeve inner wall is coaxial with this sleeve, this pivot inside is cask shape cavity, be equipped with an eccentric heavy ball in this cavity, this off -centre heavy ball's sphere diameter is less than the radius of a circle of cask shape cavity, cask shape cavity bottom surface is the sphere of inside uplift. It does not have the technological effect of strikeing, reduce the noise to have.
Description
Technical field
This utility model relates to building machinery technical field, particularly relates 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 get rid of wherein bubble, make firm by ramming, make concrete compaction combine, eliminate the phenomenon such as voids and pits of concrete, to improve its intensity, it is ensured that the quality of concrete component.Vibrating head is a kind of facility of mechanization compacted concrete, during construction, is inserted by vibrating head in concrete, gets rid of the bubble in concrete by its vibration.Current concrete vibration bar goes to drive tapper strike to be arranged on the raceway in vibrating head sleeve generally by driven by motor flexible axle and produces vibration, thus its noise is the biggest, have a strong impact on the orthobiosis of resident near construction ground, be also the health having jeopardized construction worker.
Utility model content
This utility model is intended to provide a kind of low-noise concrete poker virbrator without tapping, the problem excessive to solve concrete vibration bar noise.
Low-noise concrete poker virbrator in this programme, including motor, flexible axle and sleeve, the power transmission shaft of described motor is connected with the drive end of flexible axle；Being additionally provided with rotating shaft, the driven end of described flexible axle is fixing with the drive end of described rotating shaft to be connected, and this rotating shaft is also by the bearing described sleeve lining of connection coaxial with this sleeve；This rotating shaft is internal is drum-shaped cavity；Being provided with an eccentric heavy ball in this cavity, the sphere diameter of this bias heavy ball is less than the radius of a circle of described drum-shaped cavity；Described drum-shaped cavity floor is the sphere of inwardly protuberance.
Operation principle and beneficial effect:
Low-noise concrete poker virbrator is downwardly in concrete, and motor is rotated by driven by quill shaft rotating shaft, and the eccentric heavy ball in rotating shaft is followed rotating shaft inwall under the effect of frictional force and rotated together；Owing to the diameter of eccentric heavy ball is less than the diameter of inner chamber, rotating shaft inner chamber bottom surface is inwardly swelled spherically simultaneously, heavy ball will not rest on the axis of rotating shaft under gravity, and the centrifugal force rotating generation is pressed in eccentric heavy ball on rotating shaft inwall, the center of gravity secundly of the most whole rotating shaft, then in high speed rotating, produce great centrifugal force, cause rotating shaft together with bearing and sleeve as a body vibration, reached the effect of exciting；Owing to rotating shaft and sleeve are linked together by bearing, each other without collision, significantly reduce noise.
Further, described eccentric heavy ball surface is provided with rubber layer, increases the friction of itself and rotating shaft inwall, also its cushioning effect, reduces and rotates the noise that the heavy ball of beginning initial stage produces with the collision of rotating shaft inwall.
Further, the inwall of described rotating shaft is provided with rubber layer, increases the friction on its eccentric heavy ball surface, also its cushioning effect, reduces and rotates the noise that the heavy ball of beginning initial stage produces with the collision of rotating shaft inwall.
Further, described sleeve two ends and middle inwall are equidistantly provided with three bearings so that the supporting of rotating shaft is more stable.
Further, described rotating shaft is thrust bearing, and thrust bearing can undertake bigger radial load, is difficult to be destroyed because of the vibration of rotating shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment low-noise concrete poker virbrator；
Fig. 2 is the amplification in Fig. 1 at A.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
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 substantially as shown in accompanying drawing 1, Fig. 2:
Low-noise concrete poker virbrator in this enforcement, including motor 1, flexible axle 2, sleeve 3 and rotating shaft 4, the power transmission shaft of motor 1 is connected with the drive end of flexible axle 2, the driven end of flexible axle 2 is fixing with the drive end of rotating shaft 4 to be connected, and it is interior and coaxial with this sleeve 3 that rotating shaft 4 is connected to sleeve 3 by three, left, center, right promotion bearing；Rotating shaft 4 is internal is drum-shaped cavity, and tube cavity is placed with eccentric heavy ball 5；As in figure 2 it is shown, be designed with rubber layer on the eccentric surface of heavy ball 5 and the inwall of rotating shaft 4, the most both increase friction and also reduced noise.
Work process:
Low-noise concrete poker virbrator is downwardly in concrete, motor 1 is rotated by the rotating shaft 4 in flexible axle 2 band moving sleeve 3, the diameter of the inner chamber of rotating shaft 4 it is less than due to the diameter of eccentric heavy ball 5, the inner chamber bottom surface of rotating shaft simultaneously 4 is inwardly swelled spherically, eccentric heavy ball 5 will not rest on the axis of rotating shaft 4 under gravity, and the centrifugal force rotating generation is pressed in eccentric heavy ball on rotating shaft inwall, the center of gravity secundly of the most whole rotating shaft, then in high speed rotating, produce great centrifugal force, so that rotating shaft 4 is vibrated together with connected sleeve 3, thus complete exciting.Because sleeve 3 rotating shaft 4 is linked together by bearing, can be considered to each other does not has relative movement, the most mutually taps, and has reached to reduce the effect of noise；And promote bearing can bear bigger radial load, add the service life of low-noise concrete poker virbrator.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic too much describes at this.Should be understood that; for a person skilled in the art, on the premise of without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
