Abstract
The invention discloses a low-noise concrete vibrating rod which comprises a rod sleeve. A vibrating core rod is coaxially arranged in the rod sleeve, an eccentric cavity is arranged in the vibrating core rod, the vibrating core rod is connected to a motor through a connecting hose, simultaneously at least two bearings are sleeved on the vibrating core rod, and the bearings are both matched with the inner side wall of the rod sleeve. After optimization, the distance D between the adjacent bearings is larger than or equal to 50mm and smaller than or equal to 120mm. The low-noise concrete vibrating rod has the advantages of being low in working noise and simple in structure.
Description
Technical field
The present invention relates to the building machinery technical field, especially relate to a kind of low-noise concrete vibration bar.
Background technology
Vibrating head comprises the rod cover, and rod cover inside is provided with the eccentric shaft that is " U " font, and eccentric shaft is connected to motor by connecting hose.That is, motor drives the eccentric shaft High Rotation Speed by connecting hose, thereby makes the rod cover produce the high-frequency vibration.Like this, the rod cover is inserted in the concreting member that stirs, the bubble by in the vibration eliminating concrete makes the concrete compaction combination, eliminates the phenomenons such as concrete voids and pits.But during the eccentric shaft High Rotation Speed, noise is larger, has affected greatly near resident life, and has greatly damaged workman's health.For this reason, people have taked the method for multiple reduction vibrating head operating noise, but effect is not ideal enough, and structure is comparatively complicated.
Summary of the invention
The purpose of this invention is to provide a kind of low-noise concrete vibration bar, it has operating noise and has obtained effective reduction, and the comparatively simple characteristics of structure.
To achieve these goals, the technical solution adopted in the present invention is: low-noise concrete vibration bar, comprise the rod cover, described rod cover is inner coaxial is provided with the vibration plug, this vibration plug inside has eccentric cavity, and this vibration plug is connected to motor by connecting hose, simultaneously, cover has at least 2 bearings on the vibration plug, and bearing all matches with the inside wall that rod overlaps.
Distance B between the described adjacent bearing is: 50mm≤D≤120mm.
Distance B between the described adjacent bearing is: D=100mm.
After adopting said structure, the present invention is compared with existing technology the advantage that has and is: operating noise is lower, and structure is comparatively simple.The vibrative device of low-noise concrete vibration bar of the present invention be can High Rotation Speed the vibration plug, this vibration plug is by bearing and rod cover internal chamber wall close contact, thereby effectively raise the integraty of vibrating head, and then can effectively reduce operating noise.Simultaneously, this vibrating head used unit is less, and is comparatively simple and be easy to assembling.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Fig. 1 is that the master of embodiments of the invention looks sectional view;
Fig. 2 is that A-A of Fig. 1 is to view.
Among the figure: 10, rod cover, 20, the vibration plug, 21, eccentric cavity; 30, bearing.
The specific embodiment
The following stated only is preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see illustrated in figures 1 and 2: low-noise concrete vibration bar comprises that the rod of hollow overlaps 10.This rod cover 10 is inner coaxial is provided with vibration plug 20, and these vibration plug 20 inside have eccentric cavity 21, and this vibration plug 20 is connected to motor by connecting hose.So-called eccentric cavity 21, the inside that refers to vibration plug 20 has cavity, and the axle center of the axis deviation of this cavity vibration plug 20.Such as, the formation of this off-centre cavity 21 can be vibration plug 20 a side shaft to be provided with through hole.Simultaneously, cover has at least 2 bearings 30 on the vibration plug 20, and bearing 30 all and excellent 10 the inside wall of overlapping match.That is, vibration plug 20 is combined closely by the internal chamber wall of bearing 30 and rod cover 10.Like this, the globality of this low-noise concrete vibration bar is stronger, makes its operating noise lower.
Optimize, the distance B between the adjacent bearing 30 is: 50mm≤D≤120mm.Distance between the so-called adjacent bearing 30 refers to adjacent bearing 30 and closes on distance between the side.More excellent, the distance B between the adjacent bearing 30 is: D=100mm.Like this, further increased the globality of this low-noise concrete vibration bar.
Claims (3)
1. low-noise concrete vibration bar, comprise rod cover (10), it is characterized in that: plug (20) is vibrated in being provided with that described rod cover (10) is inner coaxial, this vibration plug (20) inside has eccentric cavity (21), and this vibration plug (20) is connected to motor by connecting hose, simultaneously, the upper cover of vibration plug (20) has at least 2 bearings (30), and bearing (30) all matches with the excellent inside wall that overlaps (10).
