In figure: 1-protective cover, 2-contiguous block A, 3-hydraulically extensible bar A, 4-base A, 5-logic control element, 6-air-cooled refrigeration device casing, 7-base B, 8-hydraulically extensible bar B, 9-contiguous block B, 10-roller bearing unit.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment: to achieve these goals, the technical solution adopted in the utility model is as follows:
As shown in Figure 1, the utility model provides a kind of automation dust-proof cover of air-cooled refrigeration device lowering or hoisting gear, comprise protective cover 1, contiguous block A2, hydraulically extensible bar A3, base A4, logic control element 5, air-cooled refrigeration device casing 6, base B7, hydraulically extensible bar B8, contiguous block B9 and roller bearing unit 10, logic control element 5 is arranged on the front end face of air-cooled refrigeration device casing 6, contiguous block B9 and contiguous block A2 is arranged on the left and right sides of protective cover 1 respectively and it is all near the installed surface of logic control element 5, base B7 and base A4 is arranged on the left and right sides of air-cooled refrigeration device casing 6 respectively, hydraulically extensible bar A3 is arranged on base A4 and it is connected with contiguous block A2, hydraulically extensible bar B8 is arranged on base B7 and it is connected with contiguous block B9.
The utility model is set to further: roller bearing unit 10 is arranged on the rear end seamed edge that protective cover 1 is connected with air-cooled refrigeration device casing 6.
The utility model is set to further: it is 45 ° that hydraulically extensible bar A3 and hydraulically extensible bar B8 tilts backwards angle.
The utility model is set to further: logic control element 5 is controlled hydraulically extensible bar A3 and hydraulically extensible bar B8 respectively by base A4 and base B7.
