Technical field
The present invention relates to vibrational structure field, particularly relate to a kind of 3X type straight-line oscillation structure.
Background technology
Traditional eccentric shaft mode of vibration
As shown in figure, most basic vibration unit is 2 vibrating shafts (also known as eccentric shaft) being linked with identical eccentricity, the gear identical by a pair size engages transmission in opposite directions, there is the eccentric fast centrifugal force F1 produced, F1 component in the horizontal direction is cancelled out each other, superimposed at 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 in the horizontal direction the logarithm of vibrating shaft, usually 4 axles, 6 axles, 8 axles ... 16 axles etc., the number of axle of the vibrating shaft (or claiming eccentric shaft) of the most maximum vibration hammer has used 16 axles, upper and lower two-layer is divided to arrange, transition gear to be added between upper and lower two-layer.The mode of vibration (as shown in Fig. 2,3,4,5) of following several 8 axles being respectively 4 axles, 6 axles, 8 axles and upper and lower two-layer distribution.
It can be seen that the vibration number of axle of all mode of vibrations is all even number from above each figure, the direction (direction of vibration) of exciting force is perpendicular to the line direction in vibrating shaft axle center all the time.
The vibrating device of this mode, when needing power (or the energy) increasing vibrational system, it is necessary to increasing the number of axle of vibrating shaft, its lateral dimension will increase, thus is difficult to enter a relative narrow space.The vibratory equipment that thus principle produces, can only be positioned on ground or outside pit-hole, it is difficult to construct in entering narrow region.
Summary of the invention
Embodiment of the present invention technical problem to be solved is, it is provided that a kind of.
Described 3X type straight-line oscillation structure, including odd number eccentric shaft, described eccentric shaft forms vibration unit by pitch wheel along eccentric shaft line, the component of they horizontal directions is cancelled out each other, component in vertical direction is overlapped mutually, form exciting force F, form a regular sine wave oscillations.
Described straight-line oscillation structure includes that three eccentric shafts, the eccentricity of upper and lower two eccentric shafts are all mr, eccentric block the centrifugal force produced is F1, and the eccentricity of middle eccentric shaft is 2mr, eccentric block the centrifugal force produced is F2, wherein F2=2F1.
Implement the embodiment of the present invention, have the advantages that
The effective component that do not has outside direction of vibration is effectively eliminated by the embodiment of the present invention, ensure effective superposition of direction of vibration component, realize the sine wave oscillations on direction of vibration, straight line eccentric shaft, increase eccentric shaft quantity easily, vibrating device cross section is constant simultaneously, it is ensured that the construction ability of narrow space.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
Embodiment of the present invention 3X type straight-line oscillation structure, including odd number eccentric shaft, eccentric shaft forms vibration unit by pitch wheel along eccentric shaft line, the component of they horizontal directions is cancelled out each other, component in vertical direction is overlapped mutually, form exciting force F, form a regular sine wave oscillations.
As shown in figure 6, most basic 3X type mode of vibration is made up of 3 eccentric shafts, three meshed transmission gear that size is identical are passed through between 3 axles, the eccentricity of upper and lower two eccentric shafts is all mr, the eccentricity of middle eccentric shaft is 2mr, relative position between them such as figure six, when gear starts to rotate, centrifugal force F1 and F2, wherein F2=2F1 is produced, from figure by eccentric block, the component of they horizontal directions is cancelled out each other, component in vertical direction is overlapped mutually, and forms exciting force F, forms a regular sine wave oscillations.Unlike traditional eccentric shaft mode of vibration, the direction of exciting force is the line by each eccentric shaft axle center.
To realize the vibration of bigger exciting force (or bigger vibrational energy), the number of axle of eccentric shaft can be increased in the line direction in eccentric shaft axle center, specifically it is to increase the element number of most basic 3X type straight-line oscillation mode, several 3X type straight-line oscillation mode through change in Fig. 7,8,9.
The like, it is also possible to extend to the mode of vibrations such as 11,13/15 axle, it is also possible to the eccentric shaft number of axle is designed as the >=even number of 4, but this version is the most unreasonable and should not use.
Can be seen that from above each figure, the structural shape of all mode of vibrations is all based on basic 3X type straight-line oscillation mode, the direction of exciting force i.e. direction of vibration are all the time by the line in each eccentric shaft axle center, each eccentric shaft is all located on straight line, therefore this vibrotechnique is referred to as 3X type straight-line oscillation technology.
The vibrating device designed by this vibrotechnique will have the least sectional dimension, duty in underground is gentle such as a Lumbricus, can walk in the narrow passage in underground easily, thus the underground engineering construction for being difficult to maybe can not carry out in the past provide a kind of may.
Dither construction equipment is one construction equipment efficiently, and 3X type straight-line oscillation technology is a kind of construction technology that can enter underground narrow space, therefore, in the most domestic and international various underground engineering constructions, 3X type straight-line oscillation technology is applied in personnel and is difficult to arrive and maybe can not reach, in being full of various risk factors and need to quickly solving the various engineerings of problem.Problem at present the most in the urgent need to address is: one, quickly enters technique for rock in pile foundation construction；Two, the rock mass Quick Driving Technology in underground tunnel project；Three, relief well, the Quick Driving Technology of ventilation shaft.
The effective component that do not has outside direction of vibration is effectively eliminated by the embodiment of the present invention, ensure effective superposition of direction of vibration component, realize the sine wave oscillations on direction of vibration, straight line eccentric shaft, increase eccentric shaft quantity easily, vibrating device cross section is constant simultaneously, it is ensured that the construction ability of narrow space.
Above disclosed it is only one preferred embodiment of the present invention, certainly can not limit the interest field of the present invention, the equivalent variations therefore made according to the claims in the present invention with this, still belong to the scope that the present invention is contained.
