Embodiment 1

[0027] Such as Figure 1-3 As shown, a steam drum installation device includes a steel frame 9, a hoist 10, a stay rope 11, a pulley block and a sling 12, wherein the pulley block includes a lower left fixed pulley 1, a lower right fixed pulley 2, an upper left fixed pulley 3, and an upper right fixed pulley 4 1. Lifting fixed pulley one 5, lifting fixed pulley two 6, moving pulley one 7 and moving pulley two 8.

[0028] The steel frame 9 is a workshop frame formed by connecting several beams 901 and columns 902. The lower left fixed pulley 1 and the lower right fixed pulley 2 are respectively symmetrically installed at the bottom of the two columns 902 opposite to the outermost side of the steel frame 9. The lower left fixed pulley 1 and the right lower fixed pulley The upper left fixed pulley 3 and the upper right fixed pulley 4 are respectively installed correspondingly on the crossbeam 901 directly above the lower fixed pulley 2, and the fixed pulley one 5 and the fixed pu...

Embodiment 2

[0036] A method for using a steam drum installation device, the method is as follows: respectively connect a stay rope 11 with the hoist 10 on the right side of the steel frame 9, the lower left fixed pulley 1, the upper left fixed pulley 3, the lifting fixed pulley-5 and the movable pulley as described above One 7, another stay rope 11 respectively connects the hoist 10 on the left side of the steel frame 9, the lower right fixed pulley 2, the upper right fixed pulley 4, the lifting fixed pulley 2 6 and the movable pulley 2 8, and separates the two slings 12 to surround the steam drum Finally fasten on both ends of the steam drum, move the pull rod 13 along the guide rail 14, adjust the positions of the lifting pulley 1 5 and the lifting pulley 2 6 through the pull rod 13, so that they correspond to the two slings 12 below, and fix the sling 12 on the On the grommet 16 of the corresponding movable pulley 1 7 or movable pulley 2 8, start the winch 10 slowly first to make the st...

Abstract

The invention discloses a steam pocket mounting device and a using method thereof. The device comprises a steel frame, a left lower fixed pulley and a right lower fixed pulley are installed at the bottom ends of two opposite stand columns on the outermost side of the steel frame respectively, and a left upper fixed pulley and a right upper fixed pulley are correspondingly installed on a cross beam over the left lower fixed pulley and the right lower fixed pulley. A first hoisting fixed pulley and a second hoisting fixed pulley are installed between the left upper fixed pulley and the right upper fixed pulley, a first movable pulley and a second movable pulley are arranged below the first hoisting fixed pulley and the second hoisting fixed pulley respectively, and slings are arranged below the first movable pulley and the second movable pulley. One end of a pull rope is fixedly connected with the first hoisting fixed pulley, and the other end of the pull rope is sequentially connected with the first movable pulley, the first hoisting fixed pulley, the upper left fixed pulley and the lower left fixed pulley and then connected with a winch which is fixedly arranged on the ground and located at one end of the left lower fixed pulley and the right lower fixed pulley. A pull rope on the other side is arranged in a same way. The device is designed according to an actual site, and the problem that an existing boiler drum hoisting device is limited by the site and cannot meet the high-altitude hoisting requirement is solved.

Description

technical field [0001] The invention belongs to the technical field of lifting installation equipment, and in particular relates to a boiler steam drum installation device and a using method thereof. Background technique [0002] Steam drum is the most important pressure component in natural circulation boiler, mainly used in sub-high pressure subcritical boiler in power production. Water in the boiler becomes qualified superheated steam, which has to go through three processes of heating, vaporization and superheating. The steam drum is the connection hub of these three processes to ensure the normal water circulation of the boiler, and there is a steam-water separation device and continuous sewage discharge inside the steam drum. device to ensure the quality of boiler steam. [0003] Boiler drums often need to be installed with hoisting equipment during installation. The Chinese patent with the notification number CN 210064970 U discloses a hoisting device for boiler ste...
