Detailed description of the invention
Embodiment referring to figs. 1 through Fig. 5 concrete vibration bar multidirectional to this utility model is described further.
nullA kind of multidirectional concrete vibration bar，Including barred body and motor，Connect on barred body 1 and have flexible pipe，The flexible pipe other end is connected on motor，Soft power transmission shaft it is provided with in flexible pipe，It is provided with motor in barred body 1 and turns 3 axles，Machine shaft 3 runs through barred body 1 and is rotationally connected with barred body 1，Machine shaft 3 is connected on motor 2 by soft power transmission shaft，Swing arm 4 it is provided with on machine shaft 3，Swing arm 4 is connected on machine shaft 3 by reciprocally swinging device 5，And swing arm 4 away from machine shaft 3 one end connect have balancing weight 6，By reciprocally swinging device 5, swing arm 4 is connected on machine shaft 3，And setting has the balancing weight 6 of constant weight on swing arm 4，When motor 2 drive motor rotating shaft 3 rotates，Swing arm 4 drives balancing weight 6 constantly to swing，The center of gravity making whole machine shaft 3 swings the most everywhere，Thus obtain multidirectional swing，Achieve three-dimensional de-bubble，Here reciprocally swinging device 5 includes fan-shaped swing chamber and servo electricity cylinder and the wobble gear engaged with servo electricity cylinder，Wobble gear switching swings intracavity in sector，Swing arm is connected on wobble gear，In order to improve the moving range of whole machine shaft 3 center of gravity，The Oscillation Amplitude of vibrating head is improved with this，Cylinder 7 can also be set on reciprocally swinging device 5，Swing arm 4 is connected on reciprocally swinging device 5 by cylinder 7，Arranging cylinder 7 can make the distance of balancing weight 6 displacement become big，It is achieved thereby that the displacement range improved，In order to realize effectively drawing to machine shaft 3 by balancing weight 6，Need machine shaft 3 is applied enough centrifugal force，It is only far from being enough by arranging a balancing weight 6，Therefore need to arrange multiple balancing weight 6，Centrifugal force in order to not make multiple balancing weight 6 bring cancels each other，Need to be provided entirely in balancing weight 6 side of machine shaft 3，So that the centrifugal force that brought by the balancing weight 6 of multiple rotations synthesize one bigger reasonable，To obtain more preferable eccentric vibrating effect，When there is eccentric rotary in machine shaft 3，Machine shaft 3 will necessarily increase with the pressure suffered by the rotating junction of barred body 1，On the one hand this can increase the frictional force of machine shaft 3 and barred body 1，Machine shaft 3 is caused to wear and tear，Affect the service life of vibrating head，For Ling Yifangmian，When external carbuncle suffered by connecting portion is excessive，Probably the machine shaft 3 of connecting portion is caused hard breakdown，Machine shaft 3 is caused to rupture，And then cause device to damage，Cause damage，In order to protect vibrating head body，Avoid contingent damage，It is accomplished by arranging elastic buffer unit in the rotating junction of machine shaft 3 with barred body 1，Here elastic buffer unit is arranged between machine shaft 3 and barred body 1，Owing to elastic buffer unit here can be subject to the most high-frequency friction，In order to improve the service life of this elastic buffer unit，Need this elastic buffer unit while having good elastic force，Also there is good anti-wear performance，Here elastic buffer unit is set to nitrile rubber pad 8，Nitrile rubber is as a kind of elastomer，Good elastic buffer ability can be provided for machine shaft 3，Nitrile rubber has the strongest anti-wear performance simultaneously，Padded coaming as rotating junction is longer for service life，Advantageously reduce cost.
nullIn order to realize omnibearing vibration froth breaking，Vibrational structure can also be installed additional on the axial direction of machine shaft 3，Here flexible connecting rod 9 can be set in machine shaft 3 opposing one end in motor 2，Flexible connecting rod 9 has gravity block 10 away from one end connection of machine shaft 3，When machine shaft 3 balancing weight 6 traction under occur swing time，Also gravity block 10 can be driven to vibrate by flexible connecting rod 9，It is achieved thereby that axial vibration，Here flexible connecting rod 9 includes outer layer bar 92 and internal layer bar 91，Outer layer bar 92 is set on internal layer bar 91，Outer layer bar 92 and internal layer bar 91 the most not back cover，It is provided with elastic component in outer layer bar 92 and internal layer bar 91，Here elastic component is set to spring 93，The two ends of spring 93 are connected to gravity block 10、On the connecting portion of flexible connecting rod 9 and machine shaft 3，Such Double layer Bar is set as flexible connecting rod 9，The vibration that can make gravity block 10 is maintained on the axial direction of machine shaft 3，In order to improve the vibration efficiency of gravity block 10，Servo electricity cylinder 11 can be set on motor 2，Machine shaft 3 is made to be connected on motor 2 by servo electricity cylinder 11，So can drive gravity block 10 by servo electricity cylinder 11，Thus it is effectively improved the oscillation distances of gravity block 10，And then improve the axial vibration effect of machine shaft 3.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
