Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Closing specific embodiment, the present invention is further explained.
As depicted in figs. 1 and 2, balance frog tamper of the invention, it includes chassis 1,1 forepart of the chassis setting
There is ram head frame 2,2 lower part of ram head frame is provided with ram head 3, and transmission device 4, the transmission dress are provided in the ram head frame 2
It puts and ratio wheel 5 is provided on 4, the ratio wheel 5 is connected to one by bead apex 6 with being arranged on the One On The Chassis breast wheel 7
It rises, the breast wheel 7 is connected by bead apex 6 with motor 8, and 1 rear portion of chassis is provided with handle 9, it is characterised in that：It
The first eccentric block 10 and the second eccentric block 11 being arranged on transmission device 4 are further included, first eccentric block 10 and second is inclined
The position that heart block 11 is arranged on transmission device 4 is in horizontal symmetrical.
In the present invention, the transmission device 4 includes first rotating shaft 41, the second shaft 42 and connection gear 43, and described the
Be fixedly installed connection gear 43 in one shaft 41 and the second shaft 42 respectively, the connection gear 43 in the first rotating shaft 41 with
Connection gear 43 in second shaft 42 is intermeshed, and the other end and the ratio wheel 5 of the first rotating shaft 41 are fixedly linked.
In the present invention, 10 and second eccentric block 11 of the first eccentric block is respectively fixedly disposed at first rotating shaft 41 and
In two shafts 42.
In the present invention, 1 lower section of chassis is additionally provided with several symmetrical idler wheels 12.
In invention in use, the motor 8 drives breast wheel 7 and ratio wheel 5 to rotate successively by bead apex 6 first,
And ratio wheel 5 drives the first rotating shaft 41 for being secured to connection to rotate again, so as to drive the rotation of the first eccentric block 10；First turn
The rotation of axis 41 has also driven the second shaft 42 to rotate by being secured to connected connection gear 43, so as to be further driven to
The rotation of second eccentric block 11, the present invention drive pairs of eccentric block by setting two pieces of eccentric blocks on ramming machine using motor 8
Make the rotation of opposite direction, lateral centrifugal force caused by them is made to cancel out each other, has reached the balance of horizontal direction.
The operation principle of the balance frog tamper of the present invention：
The balance frog tamper of the present invention drives the first eccentric block 10 and the second eccentric block 11 to make phase using motor
The rotation of negative direction constant angular velocity makes horizontal direction centrifugal force caused by them cancel out each other, and vertical direction centrifugal force phase
Mutually superposition, makes ram head 3 generate vertical up-down vibration by the rotation of ratio wheel 5, so as to achieve the purpose that backfill is compacted.
If the first eccentric block 10 and the second eccentric block 11 are attached separately in 41 and second shaft 42 of first rotating shaft, quality point
It Wei not m1And m2, the distance of eccentric block barycenter to the centre of gyration is respectively r1And r2, angular velocity of rotation is respectively ω1And ω2.Such as figure
Shown in 3, for the first eccentric block 10, the centrifugal force generated when rotating is F1, then：
Equally, the centrifugal force of the second eccentric block 11 generation is：
If the quality of the first eccentric block 10 and the second eccentric block 11, the distance of eccentric block barycenter to the centre of gyration and rotation
Angular speed difference is equal, then its centrifugal force for generating respectively is equal in magnitude, i.e.,：
F1=F2
When the steering of the first eccentric block 10 and the second eccentric block 11 is on the contrary, and from identical position or from horizontal symmetrical
Position when start simultaneously at rotation, then the centrifugal force of the first eccentric block 10 and the second eccentric block 11 and horizontal angle phase
Deng that is,：
At this moment, it is centrifuged caused by the first eccentric block 10 in 41 and second shaft 42 of first rotating shaft and the second eccentric block 11
Power, component in the horizontal direction is equal in magnitude, i.e.,：
And two horizontal component directions are on the contrary, so as to cancel out each other.Similarly, component size phase in the perpendicular direction
Deng, and direction is identical, and two power stack up, resultant force T：
This resultant force T is vertically upward or vertically downward, and size changes with centrifugal force and horizontal angle, it passes through
Bearing passes to ram head 3, is compacted backfill.
The Analysis of Periodic of the balance frog tamper of the present invention：
As shown in Fig. 4 to Fig. 9, the periodic motion of improved frog hammer can be divided into the following four stage：
First stage, as shown in Figure 4 and Figure 5, motor 8 drive the first eccentric block 10 and the second eccentric block 11 respectively along opposite
Direction be respectively rotated by 90 ° with equal-sized angular speed, in this process, 11 institute of the first eccentric block 10 and the second eccentric block
The centrifugal force of generation can be decomposed into component and horizontal force that ram head 3 is made to compress ground straight down, horizontal component therein
Equal in magnitude, direction is on the contrary, make frog hammer engine base not have the trend of horizontal movement.
Second stage, as shown in Fig. 5, Fig. 6 and Fig. 7, motor 8 drives the first eccentric block 10 and the second eccentric block 11 edge respectively
Opposite direction respectively rotates to the position of 180 degree with equal-sized angular speed, in this process, equally, the first eccentric block
10 and second the two centrifugal force horizontal components generating respectively of eccentric block 11 cancel out each other, frog hammer engine base is made to continue to keep
Horizontal direction balances.By small gradual increase, two power are superimposed two component that ram head 3 leaves ground that makes straight up, in 180 degree
Position reaches maximum value, and frog hammer ram head is made to be promoted to extreme higher position.
Phase III, as shown in Figure 7 and Figure 8, motor 8 drive the first eccentric block 10 and the second eccentric block 11 by vertical position
Horizontal position is rotated to, with second stage on the contrary, the vertical component of the centrifugal force generated respectively is gradually reduced, but direction is still vertical
Upwards.Two horizontal components continue to keep balance.
Fourth stage, as shown in Figure 8 and Figure 9, the first eccentric block 10 and the second eccentric block 11 return to homeposition simultaneously, and one
A periodic motion terminates.Eccentric block is its vertical direction component direction in horizontal position from becoming point straight down straight up
Boundary's point.In this rotary course, eccentric force straight down gradually increases, and reaches maximum in initial position, so as to eccentric block
Ram head is driven to ram ground downwards.In the horizontal direction, two horizontal components continue to keep balance.
The balance frog tamper of the present invention efficiently solves frog hammer vibration in the prior art greatly, noise
Greatly, the problem of mobile flexibility is low, and control difficulty is higher by increasing an eccentric block, is driven eccentric in pairs using motor
Block makees the rotation of opposite direction, lateral centrifugal force caused by them is made to cancel out each other so that ram head frame is no longer as existing breast-stroke
Ramming machine equally generates horizontal direction vibration, so as to achieve the purpose that reduce operating noise and reduce labor intensity, and
By installing idler wheel on frog hammer chassis, it is effectively improved the flexibility of ramming machine movement.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
