Abstract
The utility model discloses an anti-impact damper of a hydraulic excavator. The main body of the anti-impact damper is a rubber element. The inner wall of the rubber body is stuck with a metal bush for installing a connecting bolt. The outer wall of the rubber body is stuck with a metal bracket body for keeping the shape of the rubber body and meanwhile having the function of limiting amplitude. In order to prevent harsh metal collision sound generated when the bracket body of the damper collides with an excavator platform, the rim of the metal bracket body is stuck with a rubber block. The installation of the anti-impact damper can limit the maximum amplitude of an engine from exceeding a required target value and well prevent the damage to the engine and relevant components in the case of impact.
Description
Technical field
The utility model is applied to hydraulic crawler excavator engine mounting system, be when excavator is worked, both to have played damping effect, amplitude that again can limiting engine simultaneously, prevent that the amplitude of motor was excessive when excavator was hit, thus the hydraulic crawler excavator shock absorber of avoiding motor and other component to collide.
Background technology
What hydraulic crawler excavator motor in the market generally adopted is rubber shock absorber, its mounting structure as shown in Figure 1, when excavator is walked on rugged building site, when swing arm lifting and decrease speed are too fast during work, when using hydraulic hammer work, excavator complete machine fierceness is rocked, motor is subjected to very big impact, the amplitude that the motor of General Purpose Rubber shock absorber is installed can be very big, if the gap between engine blower and the wind scooper is too little, the fan of rotation at a high speed and the wind scooper phenomenon that collides can appear, can cause fan blade to fracture when serious, and cracked blade also may batter down quality accidents such as radiator.In addition, parts such as the sound absorber that links to each other with motor, empty filter, pipeline, wiring also may be collided with adjacent structural member, produce to damage, and shock absorber are also easily because of stressed excessive the damage.Generally speaking, for fear of such hidden danger occurring, when design, just the gap between fan and the wind scooper is added to enough greatly, but does the cooling effect that has but reduced radiator like this.
Summary of the invention
The purpose of this utility model is to provide a kind of can play damping effect, the excessive shock absorber that causes hidden danger of quality of amplitude in the time of preventing from again to be hit because of motor.Gap between this damper bracket body and the excavator platform is 5mm, generally speaking, the amplitude of motor can not surpass 5mm during the excavator operate as normal, this shock absorber can free vibration, when motor is subjected to impacting unusually, this damper bracket body plays position-limiting action, and the peak swing of limiting engine is no more than 5mm.In order to prevent that the collision of damper bracket body and excavator platform from the time sending ear-piercing metal impact sound, one deck rubber has bondd at the stake body edge.This damper structure is simple, easy to manufacture, and is easy to assembly, can play effective protection motor and avoid being subjected to the impact infringement.
Technical solution of the present utility model is such, comprise bolt, nut, plain washer, bolt, plain washer, spring washer, motor leg, pressing plate, go up shock absorber, following shock absorber, rubber bodies, axle sleeve, stake body, block rubber, it is characterized in that the motor leg being installed on the motor with bolt, the motor leg is connected with the excavator platform by last shock absorber, following shock absorber, push down shock absorber with pressing plate, tighten down between damper bracket body and the excavator platform upper and lower shock absorber gapped with bolts and nuts again.
There is stake body shock absorber rubber bodies outside.There is axle sleeve at rubber bodies inner face center, and the stake body outside is bonded with block rubber.
The gap of stake body and excavator platform is 0-20mm.
The utility model has the advantages that when machine works and can play good damping effect; can solve machine again is subjected to unusual the impact and causes the defective that the motor amplitude is excessive; make the motor smooth working; avoid motor and other component to collide; effectively having protected motor and related components, is the desirable shock absorber of hydraulic crawler excavator.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the rubber shock absorber cross-sectional schematic of ordinary construction.
Fig. 2 is for having adopted the utility model protecting against shock shock absorber integral installation sectional arrangement drawing.
Fig. 3 is the utility model protecting against shock shock absorber sectional plan view.
Fig. 4 is the utility model protecting against shock shock absorber cutaway top view.
Among Fig. 1～Fig. 4: nut (1), plain washer (2), pressing plate (3), last shock absorber (4), motor leg (5), bolt (6), spring washer (7), plain washer (8), bolt (9), excavator platform (10), following shock absorber (11), rubber bodies (12), axle sleeve (13), stake body (14), block rubber (15), gap (16).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1-Fig. 4, with bolt (6) motor leg (5) is installed on the motor, and motor leg (5) is connected with excavator platform (10) by last shock absorber (4), following shock absorber (11), push down shock absorber (4) with pressing plate (3), use bolt (9) and nut (1) that upper and lower shock absorber (4,11) is tightened again.Tight a bolt after (9), damper compressive strain, after the distortion, the gap between following damper bracket body (14) and the excavator platform (10) is about 0-20mm.The amplitude of motor can not surpass 5mm usually during the excavator operate as normal, and shock absorber can vibrate with engine free, and when motor was subjected to impacting unusually, following damper bracket body (14) can play position-limiting action, the about 5mm of the peak swing of limiting engine.Can effectively protect motor and related components to avoid being subjected to the impact infringement like this.
Claims (3)
1, a kind of hydraulic crawler excavator protecting against shock shock absorber, comprise nut, plain washer, pressing plate, last shock absorber, the motor leg, bolt, spring washer, plain washer, bolt, following shock absorber, the excavator platform, it is characterized in that motor leg (5) being installed on the motor with bolt (6), motor leg (5) is by last shock absorber (4), following shock absorber (11) is connected with excavator platform (10), pressing plate (10) is pressed on the shock absorber (4), use bolt (9) again, nut (1) will be gone up shock absorber (4), following shock absorber (11) is tightened, between following damper bracket body (14) and the excavator platform (10) gapped (16).
2, according to the described hydraulic crawler excavator protecting against shock of claim 1 shock absorber, main rubber body (12) the inwall bonding axle sleeve (13) that it is characterized in that hydraulic crawler excavator protecting against shock shock absorber, rubber bodies (12) outer wall bonding stake body (14), stake body (14) edge is pasted with block rubber (15).
