Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
Fig. 1 is a kind of vibratory roller liquid ungraded amplitude vibrator of the present invention, and it consists of: hydraulic motor 1 output installed on the frame 2 connects one end of vibrating shaft 5; Vibrating shaft 5 connects first member plate 4 by spline left end, right-hand member connects right end plate 9, is provided with light pipe 6 and heavy pipe 21 between first member plate 4 and right end plate 9; Light pipe 6 and heavily pipe 21 are arranged symmetrically in vibrating shaft 5 axis both sides in 180 °, and its inside is equipped with light pipe piston 7 and heavy pipe piston 23 respectively, and light pipe piston 7 is sealed with light pipe 6 by light seals 8, heavily pipe piston 23 by heavy seals 22 and heavily pipe 21 seal.The left end of light pipe 6 and heavily pipe 21, by union 3 UNICOM, is full of liquid in light pipe 6, heavily pipe 21 and union 3 that two-piston is closed.As shown in Figure 3, light pipe 6 is with heavily pipe 21 internal diameter is identical, and heavily the external diameter of pipe 21 is comparatively large, and when light pipe 6 inside is full of liquid, its gross weight is equal with not having the heavily pipe 21 of topping up; Gripper shoe 20 outer end and light pipe 6 and heavily pipe 21 is affixed, inner end and vibrating shaft 5 affixed.Vibrating shaft 5 other end is provided with swivel joint 12; Swivel joint 12 is connected with light pipe air inlet port 10 by light pipe air inlet pipe 11 above, and is connected with hydraulic lock 14 right wing by enterprising tracheae 13; Swivel joint 12 is connected with heavy pipe air inlet port 18 below by heavy pipe air inlet pipe 19, and is connected with hydraulic lock 14 left by lower inlet duct 17; Hydraulic lock 14 is connected with reversal valve 15 and source of the gas 16 in turn; Hydraulic lock 14 and reversal valve 15 are installed on the frame 2; Above-mentioned all mechanisms are all located in cylinder 24, and are provided with gusset 25 in cylinder 24, reach the object increasing cylinder 24 intensity.
If Fig. 2 is another embodiment of the present invention, its place of improving is the heteropleural of the light pipe 6 of union 3 UNICOM and heavy pipe 21, and this kind of improvement can ensure that liquid is in flow process, and cylinder 24 barycenter is in geometric center position all the time, is conducive to the balance of maintenance cylinder; The space proportion of described light pipe 6 and the heavily hollow of pipe 21 reasonably can adjust according to design needs.
Operating principle of the present invention: drive vibrating shaft 5 by hydraulic motor 1, vibrating shaft 5 drives together with the light pipe piston 7 of light pipe 6 and heavily pipe 21 and inside thereof and heavy pipe piston 23 and rotates, and the rotating speed of regulator solution pressure motor 5 can change the vibration frequency of vibrating wheels; Reversal valve 15 is for changing the airintake direction of hydraulic lock 14, when reversal valve 15 is in right position, the Compressed Gas exported from source of the gas 16 exports through hydraulic lock 14 right wing, through enterprising tracheae 13, swivel joint 12 and light pipe air inlet pipe 11, to light pipe air inlet port 10, gas push piston 7 is moved to the left, and liquid is pressed into heavily pipe 21 from light pipe 6; When reversal valve 15 is in left position, the Compressed Gas exported from source of the gas 16 through hydraulic lock 14 left, through lower inlet duct 17, swivel joint 12 and heavy pipe air inlet pipe 19, to heavy pipe air inlet port 18, gas push piston 23 is moved to the left, and liquid is pressed into light pipe 6 from heavy pipe 21.When piston 7 is in the low order end of light pipe 6, when piston 23 is in the high order end of heavily pipe 21, liquid is full of light pipe 6, and now the amplitude of vibrating wheels is zero; When piston 23 is in the low order end of heavily pipe 21, when piston 7 is in the high order end of light pipe 6, liquid is full of heavily pipe 21, and now the amplitude of vibrating wheels is maximum; When the part of liquid enters in light pipe 6, another part enters heavily pipe 21, then by the amplitude of vibrating wheels between zero-sum maximum value; By controlling the pressure of gas and flow, arbitrarily can control to enter the amount of liquid of light pipe and heavy pipe, therefore can carry out step-less adjustment to the amplitude of vibrating wheels.
