14 side walls of cylinder are respectively symmetrically connected there are two slide 5, and slide 5 uses i-beam structure, is connected to and stretches between two slides 5
The interior guide rail 10 of contracting guide rail 8 and outer guide 15 are disposed with system for compacting 7 on telescopic rail, and system for compacting 7 is by sliding block 22, vibration
The compositions such as case 24, vibrating mass 25 and squeeze board 29.
Operating process by walking and variable wide bottom disk, compacting of vibrating, framework platform Automatic Levelling three parts complete, specifically
It is as follows：
Walking and variable wide bottom disc portion, 4 inside of bilateral pedrail mechanism respectively symmetrically there are two extension sleeve 6, stretch by connection
6 internal symmetry of contracting sleeve is set there are two the first telescopic hydraulic cylinder 12, when driving can be by controlling 19 (hand of three position four-way directional control valve
It is dynamic) while adjusting the length of each first telescopic hydraulic cylinder 12 makes inner sleeve 13 and 14 relative motion of outer sleeve wide to adjust vehicle body
Degree.
Vibrate compaction part, and 14 side wall two edges of outer sleeve have been arranged symmetrically two one slide rails 5, between slide 5 respectively with it is interior
Guide rail 10 is connected with 15 one end of outer guide, and when chassis broadens, distance increases between slide 5, interior guide rail 10 and outer guide 15

It is moved along vehicle body front-rear direction.System for compacting 7 is disposed on telescopic rail 8, its movement is driven by slide block hydraulic motor 17.It should
System is drawn hydraulic oil from fuel tank 3 by hydraulic pump, is changed by the two position three way directional control valve 21 inside driver's cabin 2 and 3-position 4-way
System for compacting 7 can be completed to valve 19 (being manual) to move, when system for compacting 7 works, the pressure oil in fuel tank 3 is by filtering
In the entrance piston cell 40 of device 43 and hydraulic pump 36, since piston upper end cell 41 is directly communicated with oil return line,
Piston rod 42 rises, and vibrating mass 25 and squeeze board 29 is driven to rise, and the reversing control valve 37 that surges is promoted to act, when commutation of surging
When control valve 37 is switched to bottom, the passage of piston upper end cell 41 and oil return line is cut off, has connected pressure oil circuit, pressure oil
Road enters piston upper end cell 41, at this moment since the be stressed difference of oily active area of 42 upper/lower terminal of piston rod makes piston rod
42 move downward, and vibrating mass 25 and squeeze board 29 is driven to decline, and complete compacting, and the reversing control valve 37 that surges is promoted to act, when
When the reversing control valve 37 that surges is switched to upper, the passage of piston upper end cell 41 and in-line is cut off, has connected oil return line,
So as to complete a Xun Huan.Accumulator 38 can buffer the fluctuating of hydraulic fluid pressure in working cycle process, and can be pressure
It is real that a part of power is provided, accelerate the speed of compacting, promote the quality of compacting.The spring of upper and lower ends can absorb up and down motion
And the real-time energy of pressure, when the piston is moving down, lower end spring B is compressed, and stores energy, in piston upwards,
Hypomere spring B releases energy, and can accelerate the upward movement of piston；When the piston is moving up, the spring A of upper end can also inhale
It receives energy and releases energy when declining, snubber block 31 can also play drop and shake, and protection piston prevents accident.Pass through change
The spring of upper and lower ends can cause the resistance run into during piston up-down and energy absorption to change, so as to change
The frequency and amplitude of piston up-down；The pressure of hydraulic oil can also be changed by changing the quantity delivered of hydraulic oil；It can be with
By changing spring and hydraulic pressure oil supply amount simultaneously, the two is made to carry out the superposition or reduction of energy, changes piston up-down
Frequency and amplitude, be finally reached the frequency and amplitude for changing entire system for compacting, reach the needs of different compactions.
Chassis working connection shares an oil circuit referring to Fig. 5, walking and variable wide bottom disc portion, and the compaction part that vibrates shares separately
One oil circuit, system oil pressure are distributed by flow divider 20, and each executing agency's action control passes through 3-position 4-way hand-operated direction valve 19
It realizes.
Leveling system switch valve 27 is placed in open position during work, is referring to Fig. 9 to Figure 10 by framework platform Automatic Levelling part
Ensure safety, leveling system switch valve 27 is in lockup state during compacting operation, when 1 left side stress of framework platform is more than right side
When, framework platform 1 can be rotated counterclockwise by main hinge joint 11, at this point, the second telescopic hydraulic cylinder of left side 9 is shunk, fluid passes through
Pipeline stretches out second telescopic hydraulic cylinder 9 on right side, ensures that framework platform 1 is horizontal, framework platform is needed in guarantee
Portion's center of gravity is at center and could work normally.Leveling system flow divider 26 be used for ensure left side before and after the second telescopic hydraulic cylinder and
The second telescopic hydraulic cylinder acts simultaneously before and after right side.
