Description
Technical field
The utility model is related to vibrator technical fields, are specially a kind of hydraulic vibration exciter.
Background technology
The principle of hydraulic vibration exciter be the signal of signal generator after amplification, watched via electro-hydraulic on hydraulic vibration exciter
Taking valve control oil circuit makes piston reciprocating, is deactivated by piston tip by sharp object.Hydraulic vibration exciter at work, leads to
Piston rod reciprocating motion is crossed, if there is torsion phenomenon in piston rod work, vibrator is may result in and acutely shakes, influence exciting
The work of device or even damage vibrator.In addition, traditional vibrator cannot accurately control piston rod to the load that is applied by sharp object
Lotus and the shift length of piston rod, exciting effect are poor.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of hydraulic vibration exciter, it can prevent piston rod from going out at work
It now reverses, moreover it is possible to which for accurate control piston rod to the load applied by sharp object and the shift length of piston rod, exciting effect is good.
Its technical solution is such：A kind of hydraulic vibration exciter, it is described including electrohydraulic servo valve, hydraulic cylinder, piston rod
Piston rod is installed in the hydraulic cylinder and the hydraulic cylinder is stretched out at top, makees reciprocal fortune by electrohydraulic servo valve driving
It is dynamic, it is characterised in that：It further includes anti-torsion bar and connecting rod；The hydraulic cylinder side wall is connected with a convex block, the anti-torsion bar
And the connecting rod extends through the convex block；The piston rod stretch out the part of the hydraulic cylinder by connecting plate with it is described
Anti- torsion bar and connecting rod connection；The piston rod part is also equipped with load transducer；The convex block outer wall is also installed
There is displacement sensor, the connecting rod runs through institute's displacement sensors；The load transducer and institute's displacement sensors with
Controller electricly connects.
It is further characterized by：
Bushing is equipped between the anti-torsion bar and the connecting rod and the convex block inside.
After with such a structure, piston torsion of bar can be prevented by using anti-torsion bar, avoids turning round because of piston rod
Then caused vibrator the phenomenon that acutely shaking, the in addition use of connecting rod can also prevent the rotation of piston rod；Load
The use of sensor and displacement sensor, when can work vibrator, the load of displacement and the application of piston rod into
Row real time monitoring, once deviateing setting value, just carries out control adjustment by controller to electrohydraulic servo valve；In addition, in convex block
Portion sets bushing in the gap between connecting rod and anti-torsion bar and convex block, can be better protected from piston rod twisting.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model left view,
Fig. 3 device control planning figures in order to control.
Specific embodiment
A kind of hydraulic vibration exciter as shown in Figure 1, Figure 2, Figure 3 shows, including electrohydraulic servo valve 1, hydraulic cylinder 2, piston rod 3,
Piston rod 3 is installed in hydraulic cylinder 2 and hydraulic cylinder 2 is stretched out at top, driven by electrohydraulic servo valve 1 it is reciprocating, also
Including anti-torsion bar 4 and connecting rod 5；Hydraulic cylinder side wall is connected with a convex block 6, and anti-torsion bar 4 and connecting rod 5 extend through convex block
6, bushing 9 is equipped between 6 inside of anti-torsion bar 4 and connecting rod 5 and convex block；The part that piston rod 3 stretches out hydraulic cylinder 2 passes through connection
Plate 10 is connected with anti-torsion bar 4 and connecting rod 5；3 top of piston rod is also equipped with load transducer 7；6 outer wall of convex block is also equipped with
Displacement sensor 8, connecting rod 5 run through displacement sensor 8；Load transducer 7 and displacement sensor 8 and the automatically controlled company of controller
It connects.
In use, displacement and load parameter are selected by controller, by the way that electrohydraulic servo valve 1 is controlled to open vibrator,
Hydraulic oil in hydraulic cylinder 2 gives piston rod 3 power, so as to promote piston rod reciprocating, in motion process, and load sensing
Device 7 and displacement sensor 8 detection 3 displacement of piston rod and load output quantity, and closed-loop control is formed with controller in real time,
So as to ensure that exciting effect is good；By the way that piston rod 3 is connected with anti-torsion bar 4 and connecting rod 5, so as to effectively prevent piston rod 3
It twists at work.
More than, it is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not limited to
In this, any people for being familiar with the technology is in the technical scope disclosed by the utility model, the change or replacement that can readily occur in,
It should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with claim
Subject to protection domain.
