Description

A kind of protective device
Technical field
The utility model is related to a kind of protective devices.
Background technology
Some large slewing parts, end face is there are assembly relation, so there are roughness, dimension precision requirement, and These large slewing parts are easily destroyed its apparent mass and dimensional accuracy, then influence its assembling during transhipment, group weldering Quality.
The content of the invention
Part in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of protective device, solve large size The problem of colliding with being susceptible in slewing parts turnover, welding process, improves component assembly quality.
To achieve the above object, the utility model adopts the following technical solution:A kind of protective device, including protective cover, spiral shell Bolt, nut, screw thread protection cover, the protective cover include polylith protective plate, and polylith protective plate is combined into the protective cover of circular ring shape, institute The surface that protective cover is arranged on protection part is stated, which is equipped with multiple through holes, and protective cover passes through through hole, screw bolt and nut It is fixed on protection part, nut is arranged on the back side of protection part, and protective plate is equipped with multiple with needing part to be protected The anti-guard aperture that screw thread hole site is adapted, screw thread protection cover is equipped in the anti-guard aperture, and the screw thread protection cover is cylindrical shape.
In the above-mentioned technical solutions, the central angle of protective plate described in polylith is identical.
In the above-mentioned technical solutions, the outer wall lower end of the screw thread protection cover is equipped with one section for increasing the convex of frictional force It rises.
In the above-mentioned technical solutions, the screw thread protection cover top surface is equipped with the ring flat-plate extended to outer rim, the ring flat-plate and screw thread Protective cover is integrally formed.
In the above-mentioned technical solutions, the protective plate is bakelite plate.
The beneficial effects of the utility model are:The protective device is solved in large slewing parts turnover, welding process The problem of colliding with being susceptible to, improves component assembly quality, while takes structure of the sectional type bakelite plate as protection board, both Installation weight is alleviated, reduces device materials usage amount, while enhances protective capacities.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
A kind of protective device as shown in Fig. 1 to Fig. 5, it is described including protective cover, bolt 2, nut 3, screw thread protection cover 4 Protective cover includes polylith protective plate 1, and polylith protective plate 1 is combined into the protective cover of circular ring shape, and the protective cover is arranged on protection zero The surface of part 5, the protective cover are equipped with multiple through holes, and protective cover is fixed on protection part 5 by through hole, bolt 2 and nut 3 On, nut 3 is arranged on the back side of protection part 5, and protective plate 1 is equipped with multiple screw thread hole site phases with needing part to be protected The anti-guard aperture adapted to, screw thread protection cover 4 is equipped in the anti-guard aperture, and the screw thread protection cover 4 is cylindrical shape.Protection part 5 be To need large slewing parts to be protected.
In the above-mentioned technical solutions, the central angle of protective plate 1 is identical described in polylith.
In the above-mentioned technical solutions, the outer wall lower end of the screw thread protection cover 4 is equipped with one section for increasing the convex of frictional force It rises.The raised both ends are equipped with chamfering.
In the above-mentioned technical solutions, 4 top surface of screw thread protection cover is equipped with the ring flat-plate 6 extended to outer rim, the ring flat-plate 6 and spiral shell Line protective cover 4 is integrally formed.When screw thread protection cover 4 is packed into, ring flat-plate 6 prevent screw thread protection cover 4 entirely into protective plate 1 and Be inconvenient to take out.Ring flat-plate 6 can be in circular ring shape or other shapes.
In the above-mentioned technical solutions, the protective plate 1 is bakelite plate.
It these are only the preferred embodiment of the utility model, be not intended to limit the utility model, for this field Technical staff for, various modifications and changes may be made to the present invention.Within the spirit and principle of the utility model, Any modifications, equivalent replacements and improvements are made should be included within the scope of protection of this utility model.
