Abstract
The invention discloses a low-noise concrete vibrating bar which comprises a motor, a flexible shaft and a sleeve. A drive shaft of the motor is connected with the driving end of the flexible shaft. The low-noise concrete vibrating bar is characterized in that a rotating shaft is further arranged, the driven end of the flexible shaft is fixedly connected with the driving end of the rotating shaft, and the rotating shaft is further connected with the inner wall of the sleeve through a bearing and is coaxial with the sleeve. The interior of the rotating shaft is a cylindrical cavity. An eccentric heavy ball is arranged in the cavity, and the spherical diameter of the eccentric heavy ball is smaller than the radius of the circumference of the cylindrical cavity. The bottom face of the cylindrical cavity is a spherical face hunched inwards. The low-noise concrete vibrating bar has the advantage of lowering noise.
Description
Technical field
The present invention relates to building machinery technical field, particularly relate to a kind of low-noise concrete poker virbrator.
Background technology
During the concreting component mixed and stirred with concrete agitator, wherein bubble must be got rid of, make firm by ramming, concrete compaction be combined, eliminates the phenomenons such as concrete voids and pits, to improve its intensity, ensure the quality of concrete component.Vibrating head is a kind of facility of mechanization tamped concrete, during construction, is inserted by vibrating head in concrete, is got rid of the bubble in concrete by its vibration.Current concrete vibration bar is generally utilize motor to drive tapper percussion vibration rod sleeve pipe to produce vibration, thus concrete is vibrated, this vibrating head noise is very large, can have a strong impact on the normal life of resident near construction ground, the health also for jeopardizing construction worker.
Summary of the invention
The invention is intended to the low-noise concrete poker virbrator providing a kind of nothing to knock, to solve the excessive problem of concrete vibration bar noise.
Low-noise concrete poker virbrator, comprise motor, driving snake and sleeve pipe, the rotating shaft of described motor is connected with the input of flexible axle, it is characterized in that, flexible axle output is fixedly connected with rotating shaft, the output of described flexible axle is fixedly connected with the drive end of described rotating shaft, and this rotating shaft connects described sleeve lining by bearing; This rotating shaft inside is cylindrical cavity; Be provided with an eccentric heavy ball in this cylindrical cavity, the sphere diameter of this eccentric heavy ball is less than the radius of described cylindrical cavity; Described cylindrical cavity bottom surface is the sphere of inwardly protuberance.
Operating principle and beneficial effect:
Low-noise concrete poker virbrator inserts downwards in concrete, and motor is rotated by driving snake drive shaft, and the eccentric heavy ball in rotating shaft is followed rotating shaft inwall and rotated together under the effect of frictional force; Diameter due to eccentric heavy ball is less than the diameter of inner chamber, rotating shaft inner chamber bottom surface is inwardly swelled spherically simultaneously, heavy ball can 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, that is the center of gravity secundly of whole rotating shaft, so produce great centrifugal force in High Rotation Speed, cause rotating shaft and integrally vibrate together with bearing and sleeve, reach the effect of exciting; Because rotating shaft and sleeve 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 to rotate the heavy ball of beginning initial stage and rotating shaft inwall collides the noise produced.
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, and reduction rotates the heavy ball of beginning initial stage and rotating shaft inwall collides the noise produced.
Further, in described sleeve, front two ends and centre are equidistantly provided with three bearings, make the supporting of rotating shaft more stable.
Further, described rotating shaft is thrust bearing, and thrust bearing can bear larger radial load, is not easily destroyed because of the vibration of rotating shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment of the present invention low-noise concrete poker virbrator;
Fig. 2 is the amplification at A place in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: 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, comprise 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 fixedly connected with the drive end of rotating shaft 4, 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 inside is cylindrical cavity, is placed with eccentric heavy ball 5 in cylindrical cavity; As shown in Figure 2, the surface of eccentric heavy ball 5 and the inwall of rotating shaft 4 are all provided with rubber layer, so both increased the also noise decrease that rubs.
The course of work:
Low-noise concrete poker virbrator inserts downwards in concrete, motor 1 is rotated with the rotating shaft 4 in moving sleeve 3 by flexible axle 2, diameter due to eccentric heavy ball 5 is less than the diameter of the cylindrical cavity of rotating shaft 4, the cylindrical cavity bottom surface of rotating shaft 4 simultaneously is inwardly swelled spherically, eccentric heavy ball 5 can 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, that is the center of gravity secundly of whole rotating shaft, so produce great centrifugal force in High Rotation Speed, thus 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 have relative movement, does not mutually knock yet, and reaches the effect reducing noise; And promote bearing and can bear larger radial load, add the application life of low-noise concrete poker virbrator.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.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 manual etc. record the content that may be used for explaining claim.
