Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
Seeing Fig. 1 and Fig. 2, this utility model includes reversal valve 7 hydraulic cylinder 8 and the vibrating beam 9 being arranged on ironing machine,
Wherein, the piston-rod lower end of hydraulic cylinder 8 is fixing with vibrating beam 9 to be connected, and reversal valve 7 is arranged on hydraulic cylinder 8.Ironing machine
Including attachment means 3, screed framework 4 and striker plate 5, hydraulic cylinder 8 is arranged in attachment means 3；Attachment means 3 includes
Two to being horizontally disposed with connecting plate between the vertical plate be arrangeding in parallel, two vertical plates, hydraulic cylinder 8 is arranged on connecting plate.
Vertical plate one end of attachment means is arranged on striker plate 5, and the other end is arranged on ironing framework 4.
The lower end of the piston rod 11 of hydraulic cylinder 8 offers some screwed holes 12, and piston rod 11 afterbody is set with for regulating
The block 13 of amplitude of vibrating, and block 13 is with bolts with piston rod 11.
Described hydraulic cylinder 8 is stroke adjustable fluid pressure cylinder, and reversal valve 7 is two-position four-way solenoid directional control valve.
Seeing Fig. 1, the concrete vibrating mechanism 1 installation site in ironing machine is as shown in Figure 1.Concrete vibrating mechanism 1 is by connecting plate 2
Being fixed on screed framework 4 with attachment means 3, the front end of attachment means 3 is fixing with striker plate 5 to be connected, rear end and ironing
Plate framework 4 is fixing to be connected, and ironing machine includes that screed casing, screed casing are arranged above vibrator 6.
Operation principle of the present utility model is as shown in Figure 3.
During work, system utilizes the pressure of hydraulic oil and the effective active area of upper and lower cavity to complete rushing of the piston 10 of hydraulic cylinder 8
Journey and backhaul.When reversal valve is operated in left position, epicoele leads to hydraulic oil, and cavity of resorption takes back oil, promotes piston to move downward, completes
Stroke movement；When reversal valve is operated in right position, cavity of resorption leads to hydraulic oil, and epicoele takes back oil, promotes piston upwards, completes
Drawback movement.
Frequency of vibrating is by controlling the speed step-less adjustment that the spool of reversal valve moves left and right, and the regulation of the amplitude that vibrates is then by row
Journey adjustable hydraulic compressing cylinder 8 realizes, and concrete grammar is as follows: see Fig. 3, processes some screwed holes 12 in piston rod 11 lower end,
Then being inserted in a block 13 by piston rod afterbody, block is with bolts with piston rod, when piston upwards is to setting value
Time, block is exactly in and the position contacted at the bottom of oil cylinder, thus realizes the amplitude of vibrating required.When changing block and piston rod
Just can get the different amplitudes that vibrates during fixed position relative, thus adapt to different construction operating modes.Simultaneously it can also be seen that, vibrate
Amplitude has level to regulate.
The concrete vibrating mechanism simple in construction of this form, easy to install and use, and owing to eliminating the eccentric shaft that vibrates, operationally
Do not have the phenomenon with other parts collision impact because of vibrating beam swing；Owing to hydraulic impactor makes vibrating beam the most perpendicular
Nogata to motion, not only eliminate the impact on horizontal direction operating paver speed, and the tamping to compound can be improved
Effect, therefore also can obtain higher spreading when carrying out the disposable paving operation of big thickness.
