The utility model discloses a two-way damping and vibration reduction device for a hydraulic pipeline of a loader, which belongs to the vibration reduction device for a hydraulic pipeline of a loader. Including positioning damper, rubber damping pad, branch pipe, pressure plate, bracket and fixing bolts; the bracket is sandwiched between the positioning damper and rubber damping pad, and the branch pipe passes through the positioning damper, rubber damping pad and bracket, The upper and lower pressing plates are respectively pressed on the positioning shock absorber and the rubber shock absorbing pad; the positioning shock absorber, the rubber shock absorbing pad, the branch pipe and the pressing plate are fixed to the support by fixing bolts. The advantage is that the elasticity of the positioning shock absorber and the rubber pad can be used to absorb and reduce the vibration and pressure shock of the whole machine, reduce the fatigue damage of the pipeline, and reduce the failure feedback rate of the pipeline.
Description
Technical field
The utility model relates to loader hydraulic pipe line vibration damping equipment.It specifically is a kind of loader hydraulic pipe line bidirectional damper vibration damping equipment.
Background technique
At present, the most of employing of loader hydraulic system pipeline means of fixation directly is fixed on the vehicle frame, and the simple rubber pad that adopts at some position that has connects, even adopted rubber pad, also the fastening rubber pad that makes because of fixing bolt has lost elasticity.Owing to pipeline itself will bear the vibration that compression shock causes and bear various alternate loads and vibration from complete machine, when superposeing, vibration frequency will produce resonance, cause pipeline to destroy because of tired, present means of fixation can't reduce fatigue ruption, and then makes the circuit failure feedback rates higher.
Summary of the invention
In order to overcome existing loader makes the fatigue ruption of pipeline because of vibration and compression shock problem, the utility model provides a kind of loader hydraulic pipe line bidirectional damper vibration damping equipment, this device adopts pillar and makes location vibration damper and rubber pad have better elastic, utilize the elasticity of location vibration damper and rubber pad, absorb, reduce complete machine oscillation and compression shock, reduce the fatigue ruption of pipeline, reduce the circuit failure feedback rates.
The technical solution adopted in the utility model is: a kind of loader hydraulic pipe line bidirectional damper vibration damping equipment, and its technical characteristics is: comprise location vibration damper, rubber damper, arm, pressing plate, support and fixing bolt; Support is clipped between location vibration damper and the rubber damper, and arm passes location vibration damper, rubber damper and support, and upper and lower pressing plate is pressed in respectively on location vibration damper and the rubber damper; Location vibration damper, rubber damper, arm, pressing plate are fixed support by fixing bolt.
The beneficial effects of the utility model are: 1) when loader is worked, especially when high engine speeds, hydraulic system high pressure, alternate load from complete machine passes on the pipeline after process is located the vibration damping of vibration damper, rubber damper with vibrating, and has reduced the destruction that makes pipeline because of resonance; The pipeline rubber pad has absorbed the compression shock of hydraulic system, has reduced the destruction that makes pipeline because of impact.2) reduce the fatigue ruption of pipeline, improved the reliability of hydraulic system, reduced the fault feedback rates of hydraulic system pipeline.3) the element connection aspect in this device is subjected to the restriction in space little, arranges easily.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of the utility model device on loader;
Among the figure: 1, pressing plate, 2, the location vibration damper, 3, arm, 4, support, 5, rubber damper, 6, spring washer, 7, fixing bolt.
Embodiment
As shown in drawings, hydraulic pipe line bidirectional damper vibration damping equipment comprises location vibration damper 2, rubber damper 5, arm 3, pressing plate 1, support 4 and fixing bolt 7; Support is clipped between location vibration damper 2 and the rubber damper 5, and arm 3 passes location vibration damper 2, rubber damper 5 and support 4; Be positioned at the pressing plate 1 above the location vibration damper 2 and be positioned at rubber damper 5 following pressing plates 1 and be pressed in respectively on location vibration damper 2 and the rubber damper 5; Location vibration damper 2, rubber damper 5, arm 3, pressing plate 1 are fixed support 4 by fixing bolt 7.On Placement, select rigidity and elastoplasticity dual-support structure form for use, effectively avoided rubber shock absorber by crushing and destruction.
