In the frame 1 of wheel, frame 1 one is provided with symmetrical two counterweights 17.
As shown in Figure 2, Figure 3, Figure 4, the threephase asynchronous 16, which drives, is symmetrically arranged and is fixed with semi arch
Two bent axles 11 of neck 10 rotate, and two bent axles 11 distinguish identical gear wheel 12 by the left and right sides and little gear 13 drives, and make
The moment of both sides semi arch neck 10 is in symmetric position；Gap is provided between both sides semi arch neck 10, it is right with the middle part of T-bar 9
Together, clearance distance is longer 2~4mm than the lower end stock cross-sectional width of T-bar 9,9 or so two protrusion quarter butt axial line height of T-bar
Height residing for the center of circle of semi arch neck 10 being symmetrically arranged when rotating to minimum point equal to bent axle 11；In semi arch neck 10
Embedded with a semicircle yielding rubber 21, with the quarter butt interference fits of T-bar 9；Set between T-bar 9 and weight 4 in Plane of rotation
Have and connected by link, and the front and rear back-moving spring 7 being arranged symmetrically, T-bar 9 is maintained at vertical position in free state.
As shown in figure 5, whole device front end is equipped with wheel 2, the bottom tangent line of wheel 2 is concordant with ground, and rear end is equipped with handrail
3, whole mechanism is placed on inside frame 1, and weight 4 moves in the square chute of hollow type, and it is led by four sides
To mechanism top is equipped with upper end cover.
The operation principle of this example is：Threephase asynchronous 16 produces rotary power, is slowed down by the worm screw 15 of turbine 14
Afterwards, medianly zygomorphic little gear 13 is imparted power to by jackshaft 19, little gear 13 drives gear wheel 12 and consolidated with it
With bent axle 11, rotary motion towards the opening direction of semi arch neck 10, and two halves circular arc card are done together with semi arch neck 10
The gap slightly larger than 9 long shank diameter of T-bar is left between groove 10, such structure design can ensure in whole cyclic process
The stock of T-bar 9 will not interfere with semi arch neck 10；Due to the little gear 13 of the left and right sides on jackshaft 19 and greatly
The number of teeth difference of gear 12 is identical, therefore can ensure that two moment of semi arch neck 10 of outlet terminal are in symmetrical position
Put；T-bar 9 is cooperated by the semi arch neck 10 of two quarter butts and the left and right sides, in cyclic process upper semisection, semi arch card
Groove 10 is located at minimum point, and is rotated towards opening direction, and the quarter butt of T-bar 9 is stuck in semi arch neck 10 together to move with it, leads
Draw lower end weight above to carry, due to the special shape of semi arch neck 10, within the whole upper half cycle, the bottom of T-bar 9 all with its phase
Contact, T-bar 9 all the time can be by lifting force straight up；When moving to peak, the speed of both vertical directions is all
Zero, semi arch neck 10 will be disengaged from the contact with the bottom of T-bar 9 in subsequent time, now have two kinds of situations：When phase asynchronous
When the rotating speed of motor 16 is relatively low, it is embodied in the now vertical direction acceleration at semi arch neck 10 and is less than or equal to weight
Hammer the acceleration of 4 freely falling bodies into shape, because the lower end of T-bar 9 is not in contact with semi arch neck 10, then quarter butt can take off out of neck
From T-bar 9, together along chute falling impacts ground, completes one-shot with weight 4；When rotating speed is higher, half is embodied in
The acceleration of vertical direction at arc neck 10 is more than the acceleration of the freely falling body of weight 4, because the upper end of T-bar 9 is now located
In the state being in contact with semi arch neck 10, then now it can be by downward thrust so that and weight 4 accelerates to fall, due to
The uniform circular motion that semi arch neck 10 is done vertical direction acceleration change process for first increases and then decreases to zero, and
The acceleration of T types bar 9 begins to be equal to acceleration of gravity under free state, therefore is bound to T-bar 9 and half at a time occur
The phenomenon that arc neck 10 separates, this position can be calculated by simple mathematical formulae, as long as and rotating speed it is constant, burble point
Position will not change, whole process is equivalent to the determination initial velocity of weight one is supplied to, 4 same edge of weight afterwards
Chute falling impacts ground, complete one-shot；Therefore influence caused by rotating speed size need not be considered in real work, only
Ensure that rotating speed is identical, it is possible to excite a series of impacts to be spaced identical, energy identical pulse signal, signal is ensured with this
High s/n ratio, and the rotating speed of any regulation threephase asynchronous 16, you can convenient regulation tension weight churning frequency, be not introduced into
Other complicated structures and process；For the falling impacts ground of weight 4 during this, the pulling force for the back-moving spring 7 being arranged symmetrically will
Be applied on T types bar 9, ensure subsequent cycle cycle front T type bar 9 keep vertical state, make its with semi arch neck 10 just
