Using the above scheme, by the way that motor and eccentric wheel are installed in vibrating head, motor rotation band movable eccentric wheel rotates
To generate vibration, in use, entire vibrating head can be positioned over bridge pier or load-bearing pillar in the end connection rubber tube of connecting tube
Interior, since the distance of motor and vibration head is near and immobilizes, the vibrational energy that vibration head is subject to will not weaken substantially, because
This will not make the vibrating effect of concrete be deteriorated.
Preferably, the motor both ends are respectively arranged with the first end cover and second end cover for being fixed on vibrating tube, and described
Clutch shaft bearing is respectively and fixedly provided on one end cap and the opposite face of second end cover, the machine shaft is fixedly connected on two first axles
The inner ring held；The eccentric shaft both ends are respectively connected with second bearing, and the two second bearing outer shrouds are individually fixed in second end cover
And vibration head.
Using the above scheme, machine shaft and during eccentric shaft turns, the setting of bearing helps to reduce what is generated when rotating
Frictional force extends the service life of machine shaft and eccentric shaft.
Preferably, the vibrating tube both ends are connect respectively with vibration head and the anti-tooth of connecting tube.
Using the above scheme, the effect of anti-tooth connection can prevent vibrating tube, vibration head and connecting tube from mutually loosening.
Preferably, it is set as cavity inside the vibration head.
Using the above scheme, by the way that cavity will be set as inside vibration head, the weight of vibration head can be mitigated, can also be saved into
This.
Preferably, it is provided with bushing on the machine shaft.
Using the above scheme, by setting bushing on machine shaft to reduce machine shaft and rubbing before motor housing
It wipes, protects machine shaft, when bushing damages, conveniently replaced bushing.
Preferably, the motor includes casing, the rotor and stator being installed in the casing, the motor case outer wall
It is tightly attached to the vibration inside pipe wall.
Using the above scheme, it when vibrating head vibrates, can be improved by the way that motor case outer wall is tightly attached to vibration inside pipe wall
The stability of motor.
One end of the motor towards connecting tube is connected with the electric wire for being powered at motor.
Using the above scheme, electric wire can wear connecting tube and be connected internally to extraneous power supply to facilitate offer electric energy.
Preferably, end face of the vibration head far from the vibrating tube is cambered surface.
Using the above scheme, for cambered surface for plane, cambered surface can increase the contact area with concrete so that vibration
It is more efficient.
In conclusion the utility model has the advantages that：
1. by the way that motor and eccentric wheel are installed in vibrating head, since the distance of motor and vibration head is near and fixes not
Become, therefore the vibrational energy that vibration head is subject to will not weaken substantially, therefore the vibrating effect of concrete will not be made to be deteriorated.
2. by being connected separately with clutch shaft bearing and second bearing in machine shaft and eccentric shaft both ends so that machine shaft
It is more smooth in rotation with eccentric shaft, it improves efficiency and extends its service life.
