Abstract
A hydraulic cylinder dust cover is principally used in hydraulic cylinder dust cover in metallurgy enterprise, which includes a retractable cylindrical tube, which is characterized in that one end of the cylindrical tube is connected and fixed with the hydraulic cylinder, the other end of cylindrical tube is provided with a felt pad outer liner, a felt pad is provided on the inner side of the felt pad outer liner, a pull rope connected to the hydraulic cylinder fork is arranged on the felt pad outer liner. The utility model can effectively clean the impurity adhered on the piston-rod, avoids the dust, impurity and exogenous impurity from entering in the hydraulic cylinder to phenomenon of staining hydraulic cylinder and polluting hydraulic system.
Description
Technical field:
The utility model is mainly used in oil hydraulic cylinder dustproof of smelter.
Background technique:
The hydraulic cylinder piston rod that the coiling machine of smelter is used often rubs with the oxygen welding slag of packing tie, cutting, make and adhere to some adhesive on the piston rod, by the oil hydraulic cylinder action, bring adhesive into hydraulic system, cause the sealing of oil hydraulic cylinder end cap seriously to pull and hydraulic system pollution.Because this hydraulic cylinder travel is longer, withdrawal back distance is short again, so common oil hydraulic cylinder dust-proof cover can not be installed.
Summary of the invention:
In order to eliminate above-mentioned phenomenon, the utility model provides a kind of oil hydraulic cylinder dust-proof cover.
The utility model comprises telescopic cylindrical tube, and an end and the oil hydraulic cylinder of cylindrical tube are connected and fixed, and the other end of cylindrical tube is provided with the felt pan overcoat, and the inboard of felt pan overcoat is provided with felt pan, and felt pan puts outward and is provided with the stay cord that is connected with the oil hydraulic cylinder jaw.
The utility model can effectively will clean out attached to the impurity on the piston rod, avoids foreign matters such as dust, impurity to enter in the oil hydraulic cylinder and the phenomenon of pulling oil hydraulic cylinder and contaminated liquid pressing system.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural drawing (axially analysing and observe).
Among the figure, 1, suspension ring, 2, stay cord, 3, the felt pan overcoat, 4, felt pan, 5, cylindrical tube, 6, link.
Embodiment:
Embodiment: shown in Figure 1, present embodiment comprises telescopic cylindrical tube 5, one end of cylindrical tube 5 is equipped with the link 6 that is connected with oil hydraulic cylinder, the other end of cylindrical tube 5 is provided with felt pan overcoat 3, the inboard of felt pan overcoat 3 is provided with felt pan 4, felt pan overcoat 3 is provided with the stay cord 2 that is connected with hydraulic cylinder piston, and stay cord 2 is provided with suspension ring 1.
