Abstract
The utility model discloses a protector for the telescopic arm of a hydraulic oil cylinder, which is mainly composed of a casing body, a fastening clamp and a contact switch. The utility model is characterized in that the casing body is sheathed with the outer end of the hydraulic oil cylinder for protecting the protector from electric shocks and prolonging the service life of the protector. The utility model has the advantages of reasonable structure and easy installation and can be used for the technical field of engineering machines.
Description
Technical field
The utility model relates to engineering machinery construction safety protective gear, the definite hydraulic jack telescopic boom protective gear of saying so.
Background technique
At present; fluid cylinder telescopic boom on all kinds of engineering machinery such as excavator, loader is not all installed any protective gear; in the work progress; be easy to touch high-tension line or other wired facility in the construction environment; the personnel that drive of department are difficult for again finding above-mentioned obstacle, have directly influenced driver's life and property safety to a great extent.Moreover, under the environment condition of severe, construct, the as easy as rolling off a log fluid cylinder that spatters of dust, thus influence working life of fluid cylinder.
Summary of the invention
The purpose of this utility model is the drawback that exists at above-mentioned machinery, and hydraulic jack telescopic boom protective gear is provided, and this apparatus structure is simple, and is practical, can effectively protect the safety of driver and vehicle in the work progress, the working life of prolongation oil cylinder.
For achieving the above object, the utility model has been taked following technological scheme: hydraulic jack telescopic boom protective gear, mainly form by housing, anchorage clip, contact switch, supporting wheel.Described housing is a two ends diameter plastics circular body inequality, and the end that diameter is big is enclosed within the outer end of cylinder body, and is provided with supporting wheel between housing and the cylinder body; The end that diameter is little is enclosed within on the flexible armed lever of oil cylinder, and the termination is provided with anchorage clip, and housing is fastened on the flexible armed lever; Be provided with contact switch in outside, housing termination, its switch is provided with bridle line, and an end of rope is fixed on the housing.When the mechanical execution shear leg rises, when the obstacle of top touches bridle line on the contact switch, affect contact switch to report to the police.When machinery normally moved, housing moved around along the oil cylinder outer end with flexible rod under the effect of supporting wheel, in case telescopic boom touches the high-tension line of top in the construction environment, avoided personnel or property loss.
Owing to take technique scheme, the utility model is compared with conventional art, has technical characterstics such as simple in structure, safety coefficient height, oil cylinder long service life, can be widely used in the constructional engineering machinery technical field.
