Gear wheel 12, little gear 13, turbine 14, worm screw 15, threephase asynchronous machine 16, counterweight 17 form.In having in the middle part of described weight 4
Central hole, is fixed on coupling type base plate 5 by baffle plate 6；Coupling type base plate 5 is connected with T-bar 9 by bearing pin 8；T-bar 9 is with solid
The semi arch draw-in groove 10 being scheduled on bent axle 11 forms intermittent motion mechanism；Whole device is fixed on and is provided with handrail 3 and wheel
In frame 1, frame 1 one is provided with symmetrical two counterweights 17.
As shown in Figure 2, Figure 3, Figure 4, described threephase asynchronous machine 16 drives and is symmetrically arranged and is fixed with semi arch card
Two bent axles 11 of groove 10 rotate, and two bent axles 11 are driven by the most identical gear wheel 12 in the left and right sides and little gear 13, make two
Side semi arch draw-in groove 10 moment is in symmetric position；It is provided with gap between both sides arc neck 10, aligns in the middle part of T-bar 9,
Stand-off distance is from ratio T-bar 9 lower end stock cross-sectional width long 2～4mm, and about 9 two protrusion quarter butt axial line height of T-bar are equal to song
Axle 11 rotates to the residing height in semi arch draw-in groove 10 center of circle being symmetrically arranged during minimum point；Semi arch draw-in groove 10 is embedded with one
Individual semicircle yielding rubber 21, with T-bar 9 quarter butt interference fits；It is provided with at Plane of rotation between T-bar 9 and weight 4
Link connects, and the back-moving spring 7 being front and back arranged symmetrically with, and makes T-bar 9 be maintained at vertical position when free state.
As it is shown in figure 5, whole device front end is equipped with wheel 2, wheel 2 bottom tangent line is concordant with ground, and rear end is equipped with handrail
3, it is internal that whole mechanism is placed on frame 1, and weight 4 is moved in the square chute of hollow type, led it by four limits
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 turbine 14 worm screw 15
After, jackshaft 19 imparting power to medianly zygomorphic little gear 13, little gear 13 drives gear wheel 12 and consolidates with it
With bent axle 11, do the rotary motion towards semi arch draw-in groove 10 opening direction, and two halves circular arc card together with semi arch draw-in groove 10
Leaving the gap slightly larger than the long shank diameter of T-bar 9 between groove 10, the design of such structure can ensure that in whole cyclic process
T-bar 9 stock will not interfere with semi arch draw-in groove 10；Due to the little gear 13 of the left and right sides and canine tooth on jackshaft 19
The number of teeth of wheel 12 is the most identical, therefore can ensure that two semi arch draw-in groove 10 moment of outlet terminal are in the position of symmetry；T
Type bar 9 is cooperated, at cyclic process upper semisection, semi arch draw-in groove 10 by the semi arch draw-in groove 10 of two quarter butts with the left and right sides
Being positioned at minimum point, and rotate towards opening direction, the quarter butt of T-bar 9 is stuck in semi arch draw-in groove 10 and together moves with it, under traction
Carry on end weight, due to the special shape of semi arch draw-in groove 10, within the whole upper half cycle, all connect with it bottom T-bar 9
Touching, 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 draw-in groove 10 will be disengaged from and contacting bottom T-bar 9 at subsequent time, now has two kinds of situations: when phase asynchronous
When motor 16 rotating speed is relatively low, it is embodied in the vertical direction acceleration at now semi arch draw-in groove 10 less than or equal to weight
The acceleration of 4 freely falling bodies, owing to T-bar 9 lower end does not contacts with semi arch draw-in groove 10, then the short meeting of bar departs from draw-in groove,
T-bar 9 and weight 4, together along chute falling impacts ground, complete one-shot；When rotating speed is higher, it is embodied in semicircle
The acceleration of the vertical direction at arc draw-in groove 10 is more than the acceleration of weight 4 freely falling body, owing to T-bar 9 upper end is now in
The state contacted with semi arch draw-in groove 10, the most now it can be by downward thrust so that weight 4 accelerates to fall, due to half
The uniform circular motion that arc neck 10 is done the acceleration change process of vertical direction be first increases and then decreases to zero, and from
Begun, equal to acceleration of gravity, to be therefore bound to that T-bar 9 and semi arch at a time occur by the acceleration of T-bar under state 9
Draw-in groove 10 separate phenomenon, this position can be calculated by simple mathematical formulae, as long as and rotating speed constant, the position of burble point
Putting and will not change, whole process is equivalent to be supplied to weight one and determines initial velocity, and weight 4 is same along chute afterwards
Falling impacts ground, completes one-shot；Therefore without considering the impact that rotating speed size is brought in real work, as long as protecting
Card rotating speed is identical, it is possible to excite a series of impact interval identical, and the pulse signal that energy is identical ensures the height of signal with this
Signal to noise ratio, and arbitrarily regulate the rotating speed of threephase asynchronous 16, tension weight churning frequency can be regulated easily, be not introduced into other
Complicated structure and process；Weight 4 falling impacts ground is during this, and the pulling force of the back-moving spring 7 being arranged symmetrically with will effect
On T-bar 9, it is ensured that keep vertical state at subsequent cycle cycle front T type bar 9 so that it is with semi arch draw-in groove 10 proper engagement；
The front end of frame 1 equipped with the wheel 2 tangent with ground, has only to people equipped with handrail 3, rear end during whole device shifts
Work is lifted handrail 3 and the wheel 2 of rear end can be made to contact with ground and realize the function of movement, can need existing by base area seismic exploration
Field carries out short-range migration.
