Abstract
The utility model discloses a low noise vibrating stick, which is mainly composed of a high-speed series excited machine, a spring steel flexible shaft, a rubber hose, an irregular eccentric block, a square casing pipe, a square tip, etc. A steel ball and a spring are arranged in the irregular eccentric block. A stick head and the casing pipe are bunted by the steel ball. When the low noise vibrating stick is operated, the driving force of the high-speed series excited machine drives the irregular eccentric block to rotate at a high speed. Thus, the square casing pipe and the square tip are resonated. The utility model has the advantage of simple structure. Noise is lower than the specification of night work environmental protection. The low noise vibrating stick also has the advantages of greasy dirt prevention, water prevention, and difficult component damage. The low noise vibrating stick is the ideal machine for concrete construction in big and medium cities.
Description
The low-noise vibrating rod is a vibratory concrete tamping machinery, is specially adapted to the construction at night.
The plug-in type vibrating head of present domestic use is that vibrating arm hits and to be installed in long sleeve pipe inner conical drogue and to produce vibration, and noise is very big, generally all surpasses 85 decibels, have in addition reach 93 decibels.Have a strong impact on the resident and have a rest when using night, all can produce serious interference to the operate as normal in school, office, tourist spot on every side daytime.Current environmental protection requirement is more and more tighter, and absolute prohibition uses vibrating head after 9 o'clock of evening of big and medium-sized cities.In addition, in case immersion, immersion oil or produced iron filings and will stop vibration in the existing vibrating head sleeve pipe because of hitting friction.
The purpose of this utility model is to provide a kind of low voice vibrating head for construction, when the normal noise of surrounding environment is the architectural environment of 40-45 decibel, use low its level of noise of voice vibrating head below 55 decibels, adapt to night fully, more do not influence people's normal life and work daytime with construction.
The utility model mainly is made up of parts such as high speed series excited machine, spring steel wire flexible axle, connecting axle, rubber hose, irregular eccentric block, sleeve pipe and tips.One end of spring steel wire flexible axle is connected with high speed series excited machine axle sleeve with the screw thread guide, the outside is with rubber tube and glue pipe socket, and fix with the screw thread tapered sleeve, the other end riveting of spring steel wire flexible axle has flexible shaft end, and be fixed on the connecting axle by screw thread, connecting axle is connected with irregular eccentric block with screw thread, with tapered sleeve nipple is fixed on the rubber tube termination.Nipple is connected with the sleeve pipe internal thread again, and irregular eccentric block is equipped with steel ball and spring in the hole, and steel ball withstands tip and internal surface of sleeve pipe.
The utility model be adopt running up of irregular eccentric block and and outer tube, tip produce strong resonance, this is one of novel feature of this usefulness.Produce very big voice owing to adopting resonance principle to avoid hitting between the metal, this is two of the utility model feature.The utility model is not afraid of immersion oil, is not afraid of immersion, is not needed manually to beat to draw to shake, and this is three of the utility model feature.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model, referring to accompanying drawing.
Motor 16 is the high speed series excited machine, spring steel wire flexible axle 11 is connected with screw thread guide 15 with motor shaft, glue pipe socket 13 roll extrusion are riveted on the rubber tube 12, screw thread tapered sleeve 14 is in the glue pipe socket outside, when screw thread tapered sleeve 14 screw threads are tightened on the motor adapter sleeve, the rubber mouth of pipe also promptly is fixed motionless, nipple 8 is fastened on the rubber mouth of pipe by tapered sleeve 10, flexible shaft end 9 is riveted on the spring steel wire flexible axle 11, and be fixed on the connecting axle 7 by screw thread, connecting axle 7 links together by screw thread and irregular eccentric block 4.Nipple 8 usefulness screw threads are fixed on the sleeve pipe 5, tip 1 usefulness screw thread is fixed on the sleeve pipe, steel ball 2 and spring 3 are installed in the irregular eccentric block hole, by on tight strong firmly tip 1 and sleeve pipe 5 inwalls, irregular eccentric block 4 and connecting axle 7 are installed in the long sleeve pipe 5 by two bearings 6 steel ball 2 by spring 3.
The utility model is simple in structure, and noise is low, is not afraid of greasy dirt, not water funk, and part seldom damages except that spring, is machinery ideal in the concrete construction of large-and-medium size cities.
Claims (3)
1, a kind of low-noise vibrating rod, it is mainly by high speed series excited machine 16, spring steel wire flexible axle 11, connecting axle 7, rubber hose 12, irregular eccentric block 4 and square casing 5, square tip 1 parts such as grade are formed, an end that it is characterized in that spring steel wire flexible axle 11 connects with screw thread guide 15, glue pipe socket 13 roll extrusion are riveted on the rubber mouth of pipe, screw thread tapered sleeve 14 is enclosed within glue pipe socket 15 outsides, the other end riveting of spring steel wire has flexible shaft end 8, and with on the screw thread fixed connection shaft 7, connecting axle 7 relies on irregular eccentric block 4 and is threaded, with nipple 8 and tapered sleeve 10 one of sleeve pipe 5 is fixed with rubber hose, sleeve pipe 5 other ends are connected with square tip 1 with screw thread.
