Description
Technical field
A kind of planet speedup Link-Belt PD rod category building machinery field.
Background technology
At present, internal vibrator used in construction is that power source adds vibrating head substantially to have two kinds of forms：It is a kind of
It is planetary, it is that the tapper in vibrating head is driven by flexible axle, and one end of tapper is supported on big clearance bearing, the rolling of other end edge
Rotation and the revolution motion of pure rolling are made in road, and the tapper of rotation produces centrifugal force and acted on by raceway on rod shell and be allowed to increase
Frequently, therefore, the tapper conical surface and the raceway conical surface must be fricton-tight pure rolling, the thing such as water leaking-in, oil, dust, pure rolling in caput
Dynamic to be difficult to realize, it is powerless to form depressed or vibration in construction,
Voluntarily failure of oscillation phenomenon easily occurs in start or operation process for vibrating head, and can not voluntarily start, it is necessary to apply outer
Power, which gives shock, to be started, and high frequency noise causes serious noise pollution greatly to more than 70 decibels, makes its popularization and application
Particularly night use is very limited.Another kind is centering type, and it is to drive eccentric shaft rotation by power source drive flexible axle
Centrifugal force is formed, passing to vibrating head housing by bearing produces circular vibration, and it can be divided into series excited machine formula again by power source
With assembled in motor formula, series excited machine formula must use high speed series excited machine so that and driving snake rotating speed is very high, shortens its life-span,
Fault rate is high；Assembled in motor formula is to load motor in rod, must use frequency converter, easy heat radiation, not complicated, and cost is high.
Therefore, in construction there is an urgent need to it is a kind of overcome both the above vibrating head drawback it is reliable, rational in infrastructure, cost is low,
The novel vibrating rod of long lifespan, with adapt to construction operation there is an urgent need to.
The content of the invention
The purpose of the present invention be exactly the drawbacks of overcoming existing vibrating head innovate development it is a kind of it is reliable, rational in infrastructure,
Cost is low, the novel vibrating rod of long lifespan.
The technical scheme is that：The connecting shaft of vibrating head is connected with planetary speed increaser structure, and driving is equipped with eccentric block
Eccentric shaft, the both ends of eccentric shaft and connecting shaft by three sets of bearings in sleeve pipe, sleeve pipe front end with tip to be threadedly coupled, after
Hold with hose coupling to be threadedly coupled；The planetary speed increaser structure by the ring gear in casing, engaged with ring gear three
Individual planetary gear, with the output gear shaft of planetary gear engagement and input shaft composition be connected with planetary gear, output gear shaft and defeated
Enter axle to be supported on the high-speed bearing at embedded casing both ends.
The beneficial effects of the invention are as follows：The force-bearing situation of vibrating head internal rotation part is improved, improves the use of vibrating head
In the life-span, substantially reduce noise, can voluntarily open and shake without external force, strong adaptability, operation is comfortable, reliable, cost is low,
Long lifespan, modern design, rational in infrastructure, maintenance is easy.

Embodiment
The details and the course of work of the present invention are described in detail with reference to the accompanying drawing of the present invention.The connecting shaft 7 and planet of vibrating head
Speed increasing mechanism 12 is connected, and eccentric shaft 3 of the driving equipped with eccentric block 4, the both ends of eccentric shaft 3 and connecting shaft 7 are supported by three sets of bearings 9
In sleeve pipe 2, the front end of sleeve pipe 2 is with tip 1 to be threadedly coupled, and rear end is with hose coupling 8 to be threadedly coupled.In the present embodiment,
The front end of bearing 9 in connecting shaft 7 carries out axially position with shaft block ring 10, and eccentric block 4 is with two sets of screws 15 and elasticity
Packing ring 14 is firm on eccentric shaft 3, and wave washer 16 is housed between the bearing 9 and tip 1 of the front end dress of eccentric shaft 3.It is described
Planetary speed increaser structure 12 by the ring gear 12-4 in casing 12-1, the three planetary gear 12-6 engaged with ring gear 12-4,
Formed with the planetary gear 12-6 output gear shaft 12-3 engaged and the input shaft 12-5 being connected with planetary gear 12-6, output gear
Axle 12-3 and input shaft 12-5 is supported on the high-speed bearing 12-2 at embedded casing 12-1 both ends.In the present embodiment, planet increases
The rear and front end of fast mechanism 12 and support eccentric shaft 3, connecting shaft 7 two sets of bearings 9 between be respectively provided with preceding spacer 5 and rear spacer
6, with the tightening of fluting tapered end holding screw 11 between sleeve pipe 2 and planetary speed increaser structure 12, eccentric shaft 3 and output gear shaft 12-3 it
Between connected with key 13.Overall structure can also be made in eccentric shaft 3, and planetary speed increaser structure 12 can also be other machinery booster engine
Structure, planetary gear 12-6 be alternatively one, two or more.Planet is driven by connecting shaft 7 by flexible axle when this vibrating head works
Speed increasing mechanism 12 operates, and three in planetary speed increaser structure 12 planetary gear 12-6 is both around own axis, and with input shaft 12-
5 axis is that the main shaft of vibrating head rotates, and drives eccentric shaft 3 to rotate by output gear shaft 12-3, produces centrifugal action
In on sleeve pipe 2 and being allowed to speedup, this centrifugal force is exactly the exciting force of vibrating head, and the exciting force passes to concrete component, is formed
To the perturbed force of concrete, through vibration after a while, the space in concrete is filled, and concrete component obtains closely knit.
That is, this vibrating head is both planetary, and the drawbacks of overcome existing planetary vibrating head, it is using unique planet
Speed increasing mechanism, avoid the harshness that the existing planetary vibrating head tapper conical surface and the raceway conical surface must be fricton-tight pure rolling and want
Ask, even if the thing such as water leaking-in, oil, dust in caput, construction suffered will not be formed it is depressed or vibration it is powerless, can not by external force
Voluntarily open and shake, noise is low；This vibrating head is again centering type simultaneously, equally overcomes existing Link-Belt PD rod driving snake and turns
Speed is very high, service life reduction, fault rate are high or must use frequency converter, non-easy heat radiation, complicated, the drawbacks such as cost is high.Local oscillator
Dynamic rod planetary speed increaser structure 12 has small volume, in light weight, bearing capacity is high, service life is long, smooth running, noise are low, defeated
The characteristics of going out big moment of torsion, efficiency high, performance safety.The beneficial effects of the invention are as follows：Improve the stress of vibrating head internal rotation part
Situation, the service life of vibrating head is improved, substantially reduces noise, can voluntarily opened and shake without external force, strong adaptability, behaviour
Make that comfortable, reliable, cost is low, long lifespan, modern design, rational in infrastructure, maintenance is easy.
