It cancels out each other, it is superimposed in the component of vertical direction, form a regular sine wave oscillations.
To realize the vibration of bigger exciting force (or bigger vibrational energy), need to increase vibrating shaft in the horizontal direction
Logarithm, usually 4 axis, 6 axis, 8 axis ..., 16 axis etc., the axis of the vibrating shaft (or eccentric shaft) of current maximum vibration hammer
Number has used 16 axis, and a point upper layer and lower layer are arranged, transition gear is added between upper and lower two layers.Following several respectively 4 axis, 6 axis, 8
The mode of vibration of axis and 8 axis of upper layer and lower layer distribution (as shown in Fig. 2,3,4,5).
As can be seen that the vibration number of axle of all mode of vibrations is all even number, the direction (vibration of exciting force from above each figure
Direction) always perpendicular to the line direction in vibrating shaft axle center.
The vibration device of this mode, when needing to increase power (or energy) of vibrational system, it is necessary to increase vibration
The number of axle of axis, its lateral dimension just will increase, to be difficult to enter an opposite narrow space.Thus the vibration of principle production
Dynamic equipment, can only be placed on ground or outside pit-hole, it is difficult to enter in narrow region and construct.
Summary of the invention
The technical problem to be solved by the embodiment of the invention is that providing a kind of 3X type straight-line oscillation structure.
The 3X type straight-line oscillation structure, including odd number eccentric shaft, the eccentric shaft pass through pitch wheel edge
Eccentric shaft line forms vibration unit, and the component of their horizontal directions is cancelled out each other, is overlapped mutually in the component of vertical direction, shape
At exciting force F, form a regular sine wave oscillations, the odd number eccentric shaft is parallel to each other, and be arranged in it is same vertical
In plane, the direction of the exciting force passes through the line in the axle center of each eccentric shaft.
The straight-line oscillation structure includes three eccentric shafts, and the eccentricity of upper and lower two eccentric shaft is all mr, by eccentric block
The centrifugal force of generation is F1, and it is F2 by the centrifugal force that eccentric block generates that the eccentricity of intermediate eccentric shaft, which is 2mr, wherein F2=
2F1。
Implement the embodiment of the present invention, has the advantages that：
The embodiment of the present invention will not have effective component to effectively eliminate outside direction of vibration, guarantee having for direction of vibration component

Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, the present invention is made into one below in conjunction with attached drawing
Step ground detailed description.
3X type straight-line oscillation structure of the embodiment of the present invention, including odd number eccentric shaft, eccentric shaft pass through intermeshing tooth
Wheel forms vibration unit along eccentric shaft line, and the component of their horizontal directions is cancelled out each other, mutually folded in the component of vertical direction
Add, form exciting force F, forms a regular sine wave oscillations.
As shown in figure 6, most basic 3X type mode of vibration is made of 3 eccentric shafts, identical by size between 3 axis
Three gears engaged transmission, the eccentricity of upper and lower two eccentric shaft is all mr, and the eccentricity of intermediate eccentric shaft is 2mr, they it
Between relative position such as figure six centrifugal force F1 and F2, wherein F2=2F1, by scheming are generated by eccentric block when gear starts turning
In it is found that the component of their horizontal directions is cancelled out each other, be overlapped mutually in the component of vertical direction, form exciting force F, form one
The sine wave oscillations of a rule.Unlike traditional eccentric shaft mode of vibration, the direction of exciting force is by each eccentric shaft
The line in axle center.
It, can be in the line direction in eccentric shaft axle center to realize the vibration of bigger exciting force (or bigger vibrational energy)
Increase the number of axle of eccentric shaft, is specifically the element number for increasing most basic 3X type straight-line oscillation mode, Fig. 7,8,9 are several
3X type straight-line oscillation mode by variation.
And so on, the mode of vibrations such as 11,13/15 axis can also be extended to, the eccentric shaft number of axle can also be designed as >=4
Even number, but this structure type is extremely unreasonable and should not use.
It can be seen that from above each figure, the structural shape of all mode of vibrations is all in a manner of basic 3X type straight-line oscillation
Basis, the direction of exciting force i.e. direction of vibration pass through the line in each eccentric shaft axle center always, and each eccentric shaft is all located at one
On straight line, therefore this vibrotechnique is known as 3X type straight-line oscillation technology.
Working condition of the vibration device designed by this vibrotechnique by the sectional dimension with very little, in underground
A gentle such as earthworm, it may be convenient to be walked in the narrow channel in underground, thus to be difficult to carry out or can not can be carried out in the past
Underground engineering construction provide a kind of possibility.
High-frequency vibration construction equipment is a kind of efficiently construction equipment, and 3X type straight-line oscillation technology is that one kind can enter ground
The construction technology of lower narrow space, therefore, in domestic and international various underground engineering constructions from now on, 3X type straight-line oscillation technology will be answered
It is difficult to reach or can not reach used in personnel, full of in various risk factors and the various engineerings that need to quickly solve the problems, such as.
Problem most in the urgent need to address is at present：One, quickly enter technique for rock in pile foundation construction；Two, in underground tunnel project
Rock mass Quick Driving Technology；Three, the Quick Driving Technology of relief well, ventilation shaft.
The embodiment of the present invention will not have effective component to effectively eliminate outside direction of vibration, guarantee having for direction of vibration component
The sine wave oscillations on direction of vibration is realized in effect superposition, and straight line arranges eccentric shaft, convenient to increase the eccentric number of axle, is shaken simultaneously
Dynamic device section is constant, guarantees the construction ability of narrow space.
Above disclosed is only a preferred embodiment of the present invention, cannot limit the power of the present invention with this certainly
Sharp range, therefore equivalent changes made in accordance with the claims of the present invention, are still within the scope of the present invention.
