Abstract
The utility model relates to an external vibrator which comprises a casing and a motor arranged at the middle part of an inner chamber of the casing, wherein the motor is a motor with a big interstitial structure, and both ends of a motor shaft are respectively provided with a vibrating block. Vibrating sleeves are respectively sheathed on the inner wall of the casing corresponding to the vibrating block, and a gap is arranged between the inner wall of the vibrating sleeve and the corresponding vibrating block. With the structure, the vibrating blocks arranged on both ends of the motor shaft are contacted with the vibrating sleeve arranged on the inner wall of the casing, and a planet roller vibration is produced. Therefore, the aim of improving vibration frequency is achieved. Besides, the utility model enhances the vibration effect by 30% to 50%, and reduces the volume of the external vibrator.
Description
The utility model relates to concrete formation machinery in a kind of building operations, relates to a kind of outside formula vibrator specifically.
In the construction industry concrete construction, for reducing in the concrete frictional force between cement mortar viscosity and aggregate, and reduction concrete structure viscosity and limiting shearing stress, improve concrete flowability, fillibility, compactness, intensity and finish to reach, must carry out the moulding vibration concrete.Present employed concrete formation vibratory equipment has outside formula vibrator, it is centrifugal that its structure is mainly eccentric block, promptly be respectively arranged with an eccentric block at the two ends of common electrical arbor, this eccentric block is when the motor shaft low speed rotation, produce centrifugal force and drive the hull vibration that is installed in described motor outside, but the outside formula vibrator of this structure has many deficiencies, and as volume is big, vibration frequency is lower, exciting force is less, vibrating effect is relatively poor etc.
The purpose of this utility model provides a kind of outside formula vibrator with regard to being at above-mentioned existing in prior technology deficiency.
The purpose of this utility model can realize by following technical measures:
The utility model comprises a housing, and the motor that is arranged on housing inner chamber middle part, described motor is a big interstitial structure motor, be respectively arranged with a vibrating mass at the two ends of described motor shaft, on inner walls, be respectively installed with a vibration cover, leave the gap between described vibration cover inwall and the corresponding vibrating mass corresponding to described vibrating mass position.
The longitudinal section of described vibrating mass is taper, also can be rectangle or circle certainly.For the ease of changing the vibration cover, on described vibration cover inwall, be set with cover in.
Advantage of the present utility model just is by at described housing housing inner chamber middle part one big interstitial structure motor being set, and is respectively arranged with a vibrating mass at the two ends of described motor shaft.During work, because the gap is bigger between the stator and rotor of described motor, rotor produces radially when rotated, and string moves, cause motor shaft to radially wobble, motor shaft radially wobbles, and makes vibrating mass that is arranged on the motor shaft two ends and the vibration cover that is arranged on the inner walls collide, produce the vibration of planet roller bearing, improve the purpose frequently of shaking thereby reached, improved vibrating effect 30%-50%, also reduced the volume of outside formula vibrator simultaneously.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the figure that partly cuts open of the present utility model.
The utility model describes in further detail below in conjunction with specific embodiment (accompanying drawing):
As shown in the figure, the utility model comprises a housing 1, and the motor 2 that is arranged on housing 1 inner chamber middle part, and described motor 2 is a big interstitial structure motor, is respectively arranged with a vibrating mass 4 at the two ends of described motor shaft 3, and the longitudinal section of described vibrating mass 4 is taper.Be respectively installed with a vibration cover 5 corresponding to described vibrating mass 4 positions on housing 1 inwall, be set with in one on these vibration cover 5 inwalls and overlap 6, described vibration is overlapped between 5 inwalls and the corresponding vibrating mass 4 and is left the gap.
