It has a good protection effect on the long hydraulic motor and reducer.
Description
Technical field
The utility model relates to a kind of protective cover, and specifically a kind of large excavator hydraulic system protective cover, belongs to excavator hydraulic system protective cover technical field.
Background technology
At present, giant caterpillar formula hydraulic crawler excavator is mainly used in mine operation, its industrial and mineral is more severe, excavator is got off in running gear, left-right longeron is all configured with fluid pressure drive device, there are many fluid pressure lines, be subject to stone extruding and wearing and tearing in the course of the work, so large excavator is generally all equipped with protective cover.By the restriction of drive unit and lower bassinet structure, many large excavator drive units are all directly exposed to beyond longitudinal beam structure part, due to liftoff comparatively near, are easily impacted.Existing part excavator only increases anti-collision structure in liftoff nearer position, but still has part drive unit outside exposed, or protective cover intensity is low, fragile, can not to get off drive unit and pipeline by available protecting.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of large excavator hydraulic system protective cover, can to get off drive unit and pipeline by available protecting.
To achieve these goals, a kind of large excavator hydraulic system protective cover that the utility model adopts, comprise symmetrical two groups of guard shields, often organize guard shield to be made up of upper shield and lower shield respectively, on the longeron that described upper shield is arranged on excavator and H frame, for the protection of stretching out the pipeline being connected to fluid pressure drive device from H frame; Described lower shield is arranged on the driving seat on longeron, for the protection of fluid pressure drive device.
Preferably, described upper shield comprises upper shield main body and fagging, is bolted to connection between described boot main body and fagging.
Preferably, described lower shield comprises lower shield main body and cover plate, is bolted to connection between described lower shield main body and cover plate.
Preferably, described upper shield and lower shield are equipped with the handrail for gripping.
Preferably, described upper shield is equipped with the L-type otic placode for connecting and installing hole, described lower shield has installing hole.
Preferably, described upper shield and lower shield are equipped with reinforcing rib.
Compared with prior art, the utility model adopts symmetrical two groups of guard shields, often organize guard shield to be made up of upper shield and lower shield respectively, on the longeron that upper shield is arranged on excavator and H frame, can protect and stretch out from H frame the pipeline portions being connected to fluid pressure drive device, lower shield is arranged on the driving seat on longeron, can protect fluid pressure drive device; The cooperation of upper shield and lower shield makes to get off in drive unit and the complete besieged guard shield of pipeline, achieves comprehensive available protecting of get off drive unit and pipeline.And upper shield and lower shield all can be reinforced structure, better protection drive unit and pipeline.Guard shield can firmly be fixed on vehicle frame, and fabricated shield structure is more convenient dismounting and maintenance also, has good protective effect for longer hydraulic motor and reductor.
