In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of lifting device that end cap is embedded in the barrel-type compressor end cap in the compressor housing that is used for.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises to be taken over and flange, takes over the shape into " C "; Flange is located at an end of adapter, is used for the end cap interior with being embedded in compressor housing and is connected.
Wherein: be equipped with gusset in the bending place of taking over the inboard and the outside of adapter; Be arranged on the gusset of taking over the outside and be provided with a plurality of erection opening; Be arranged on the gusset shape of taking over the outside and to take over radial cross section identical, and with the axis coplane of adapter; Described adapter comprises first and second adapter and first and second elbow, one end of first elbow connects first and takes over, the other end is connected with second end of taking over, and second the other end of taking over is connected the other end adpting flange of second elbow with an end of second elbow; Take over the inboard bending place that forms with first elbow at first and second and be provided with the 3rd gusset; Take over the inboard bending place that forms with second elbow second and be provided with first gusset; Outside taking over, " C " shape of first and second adapter and the formation of first and second elbow is provided with second gusset; The shape of described second gusset is taken over identical with the radial cross section of first and second elbow with first and second, and takes over first and second and the axis coplane of first and second elbow; On second gusset in the first adapter outside, be provided with a plurality of erection opening; Described end cap by double-screw bolt and nut tightly on flange.
Advantage of the present utility model and good effect are:
1. the utility model can carry out dismounting to the end cap that is embedded in the casing, and is simple in structure, easy to operate.
2. the utility model all is provided with gusset in the bending place and the outside taken over, has guaranteed the intensity of lifting device, and is safe.
3. by determining the position of erection opening, can guarantee that end cap each turning surface in assembling and dissembling process remains and the outer cage coaxial state, can convenient and swiftly send end cap into the precalculated position effectively.
4. end cap is embedded in the casing, has reduced the external diameter and the thickness of end cap, has saved raw material, has reduced cost of production.
