Abstract
The utility model relates to an excavator hydraulic pipeline protecting cover, and belongs to the technical field of protecting of engineering mechanical pipelines. The excavator hydraulic pipeline protecting cover comprises a pair of protection cover bodies which are symmetrical left and right, wherein according to each protection cover body, a cavity is formed by a protection cover upper layer, a protection cover lower layer and a protection cover middle layer which is perpendicularly fixed to the protection cover upper layer and the protection cover lower layer, each protection cover upper layer and the each protection cover lower layer are respectively fixed on a walking beam, and the protection cover bodies do not make contact with a middle frame. The excavator hydraulic pipeline protecting cover has the advantages that due to the fact that the protection cover bodies are only fixedly connected with the walking beam and do not make contact with the middle frame, when the middle frame is in the two states of shrinking and stretching, namely, when an excavator is in the states of working and transportation, the protection cover bodies can be fixed on the walking beam all the time and do not need to be dismantled, and a hydraulic pipeline is protected well.
Description
Technical field
The utility model relates to a kind of excavator fluid pressure line protective cover, belongs to piping in construction machinery guard technology field.
Background technology
Crawler hypraulic excavator is one of capital equipment of engineering machinery; it is the most topmost extractive equipment in the opencut; in the crawler hypraulic excavator running gear; left and right sides walking beam all is equipped with fluid pressure drive device; thereby have many fluid pressure lines, and operating mode is than under the condition of severe in the mine, and fluid pressure line is subjected to extruding and the wearing and tearing of sandstone easily; for the protection fluid pressure line, generally all can be equipped with protective cover.The protective cover protection form that adopts mostly is fixed at present, be anchored on vehicle frame and the walking beam, can only be in the duty of excavator, assemble use when namely vehicle frame launches, when excavator need move when being in travel position when remote, for realizing its whole Transporting, need make the spacing of walking beam suitably reduce by the contraction of middle vehicle frame, in such cases, then need to dismantle protective cover, this moment, fluid pressure line all was exposed to the outside, very easily was damaged.
Summary of the invention
At the problem that above-mentioned prior art exists, the utility model provides a kind of excavator fluid pressure line protective cover, makes the excavator vehicle frame all can well protect fluid pressure line when launching or shrink, and avoids being damaged.
To achieve these goals, the technical solution adopted in the utility model is: a kind of excavator fluid pressure line protective cover, comprise symmetrical one group of guard shield, each guard shield is formed a cavity by guard shield upper strata, guard shield lower floor and vertical fixing in the guard shield intermediate layer of guard shield upper strata and guard shield lower floor, guard shield upper strata and guard shield lower floor are separately fixed on the walking beam, and guard shield and middle vehicle frame are contactless.
The beneficial effects of the utility model are: guard shield is only fixedlyed connected with walking beam; with do not contact between the middle vehicle frame; in vehicle frame shrink or launch under the two states be excavator in working order with travel position under; protective cover can be fixed on the walking beam always; need not dismounting, well protect fluid pressure line.
Description of drawings
Fig. 1 uses view for the utility model;
Fig. 2 is vehicle frame deployed condition front view in the utility model;
Fig. 3 is vehicle frame deployed condition vertical view in the utility model;
Fig. 4 is vehicle frame contraction state front view in the utility model;
Fig. 5 is vehicle frame contraction state vertical view in the utility model.
Among the figure: 1, guard shield upper strata, 2, the guard shield intermediate layer, 3, guard shield lower floor, 4, bolt, 5, middle vehicle frame, 6, walking beam.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Extremely shown in Figure 5 as Fig. 1: the utility model comprises symmetrical one group of guard shield, each guard shield is formed a cavity by guard shield upper strata 1, guard shield lower floor 3 and vertical fixing in the guard shield intermediate layer 2 of guard shield upper strata 1 and guard shield lower floor 3, guard shield upper strata 1 and guard shield lower floor 3 are fixed on the walking beam 6 by bolt 4 respectively, and guard shield and middle vehicle frame 5 are contactless.When middle vehicle frame 5 contractions or expansion, can not interfere with guard shield, therefore, when crawler hypraulic excavator betransported, not need to dismantle guard shield.The cavity body structure that closely is connected to form by guard shield, when middle vehicle frame 5 launches or shrinks, can both be well with the fluid pressure line protection in cavity, the damage of avoiding fluid pressure line to expose causing.
