Detailed Description
In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the utility model is further described in detail by combining the embodiments and the drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. The following describes the technical scheme of the present utility model in detail with reference to examples and drawings, but the scope of protection is not limited thereto.
Referring to fig. 1-3, this embodiment provides a flange seal ring gasket mounting and lifting tool, where the ring gasket 1 is located between two flanges 2, and the ring gasket 1 is an octagonal gasket or an elliptical gasket. The two flanges 2 are connected by a flange fastening bolt 7.
The whole lifting tool is made of steel; the lifting tool comprises a groove-shaped bracket 3, wherein the groove-shaped bracket 3 is used for supporting the bottom of a flange 2 at one side, a first jackscrew 4 is vertically connected to one side wall of the groove-shaped bracket 3, a second jackscrew 5 is vertically connected to the other side wall of the groove-shaped bracket 3, and the first jackscrew 4 and the second jackscrew 5 are in threaded connection with the groove-shaped bracket 3; the first jackscrew 4 and the second jackscrew 5 are oppositely arranged, and the groove-shaped bracket 3 is fixed at the bottom of the flange 2 at one side through the first jackscrew 4; and a third jackscrew 6 is vertically connected to the second jackscrew 5 in a threaded manner, and the third jackscrew 6 is positioned outside the side wall of the groove-shaped bracket 3.
