Abstract
The utility model relates to a noiseless vibration rod for building engineering. The utility model comprises a motor, a flexible shaft and a vibrating rod body of a rolling cone, which is connected with the flexible shaft into a whole body, wherein, a screw sleeve, a bearing and a baffle sleeve are orderly arranged on the periphery of a connecting position between a rolling cone and the flexible shaft. The middle back part of the rolling cone is provided with a silencing outer sleeve. A rolling way sleeve is arranged on the periphery of a cone body on the middle of the rolling cone. A gap is formed between the rolling way sleeve and the cone body. A heat radiating sleeve is arranged outside the rolling way sleeve. A seal head sleeve is arranged on the front part of the rolling cone. The silencing outer sleeve, the rolling way sleeve and the seal head sleeve are all made of non-metal silencing materials. The utility model adopts non-metal nylon as the materials of the outer sleeve. Thus, the noises of a vibrating rod can be decreased below 60 dB. The utility model has the advantages of easy improvement and reduction of vibrating rod weight.
Description
The utility model relates to the instrument of in a kind of construction work vibratory concrete being tamped, i.e. engineering noiselessness vibrating head.
The structure of concrete vibration bar is at present: the peripheral all clad metal pipe boxes of the tapper axis body that links to each other with power source and flexible axle, owing to produce resonance when tapper and the work of metal pipe box, operating noise is up to more than 200 decibels, greatly disturb urban environment, seriously influenced people's normal life and work.
Task of the present utility model is to overcome the defective that existing vibrating head exists, and designs a kind of noise elimination noiselessness vibrating head.
The utility model is on the basis of existing vibrating head, with the metal sleeve of tapper periphery, is replaced with nonmetal noise reduction sleeve pipe, noise can be reduced to below 60 decibels like this.The utility model comprises power source motor, flexible axle that is connected with motor and the tapper vibration barred body that combines as a whole with flexible axle, its periphery of point of attachment at tapper and flexible axle is equipped with gland nut and bearing successively, near bearing the shelves cover is housed, at gland nut, bearing and the peripheral postmedian until tapper of shelves cover are provided with overcoat, the cone periphery at tapper middle part is provided with the raceway cover, between raceway cover and cone, leave the gap, the outer heat radiation cover that is provided with of raceway cover, be surrounded by the end socket cover in the tapper front portion, technical characterictic of the present utility model is said overcoat, raceway cover and end socket cover all adopt nonmetal quieter material to make.
The utility model is owing to adopt nonmetal nylon to make the noise reduction lagging material, so can make the vibrating head noise be brought down below below 60 decibels of national standard, also has simultaneously and is easy to improve, and the vibrating head overall weight such as alleviates at advantage.
Be described in detail in conjunction with the specific embodiment of the present utility model below by accompanying drawing.
Accompanying drawing is the whole sectional view of utility model.
Referring to accompanying drawing, tapper 5 is connected as one with flexible axle 10, in tapper 5 and its periphery of point of attachment of flexible axle 10 gland nut 1 and bearing 3 are housed successively, between swivel nut 1 and bearing 3, place sealing ring 2, near bearing 3 shelves cover 4 is housed, until the postmedian position of tapper noise reduction overcoat 6 is set at gland nut 1 bearing 3 and shelves cover 4 peripheries, leave a swing space between overcoat 6 and the stage casing tapper, the peripheral raceway cover 8 of the cone at tapper 5 middle parts, between raceway cover 8 and cone, leave the gap, the outer heat dissipation metal cover 7 that is provided with of raceway cover, be surrounded by end socket cover 9 in the tapper front portion, noise reduction overcoat 6, raceway cover 8 and end socket cover 9 all adopt nonmetal quieter material to make, and this quieter material adopts engineering nylon; For guaranteeing the sealing of vibrating head tapper and peripheral casing, adopt between noise reduction overcoat, end socket cover and the heat radiation cover 7
The shape thread connection.
