Embodiment Construction
[0023] Such as figure 1 , figure 2 , image 3 as well as Figure 4 Shown, a kind of drum-shaped strainer drum frame installation method, this method comprises the following steps:
[0024] In the first step, all the main spokes 2 are sequentially installed on the hub 11 of the main shaft 1, and two adjacent main spokes 2 are connected by connecting pieces 22; a sub-spoke 31 and a sub-beam 32 are assembled to form a Group the sub-spoke group 3, so that each sub-spoke 31 is fixedly connected with a sub-beam 32;
[0025] In the second step, the main beam 21 is installed on the main spoke directly above the main shaft, and the first main spoke on which the main beam is installed is called the first main spoke, and the main spoke adjacent to the first main spoke is called It is the second main spoke, and so on. Use a hoist (not shown in the figure) to pull the first main spoke, so that the second main spoke rotates to the top of the main shaft 1, and then install the main bea...

The invention provides a method for mounting a drum framework of a drum strainer in order to solve the problems of high mounting difficulty, low safety factor, low operation efficiency and the like of existing mounting methods. The method includes: sequentially mounting main spokes, connecting each two adjacent main spokes by connectors; assembling an auxiliary spoke group; mounting main cross beams on the main spokes and mounting the auxiliary spoke group on the connectors; using circumferential connection angles to connect all main and auxiliary cross beams; annularly mounting gear ring fixing grooves to the middles of the top ends of the cross beams on the main and auxiliary spokes, and fixing gear rings in the gear ring fixing grooves; circularly fixing a frame on each of two sides of each main cross beam and auxiliary cross beam. Owing to the method for mounting the drum framework of the drum strainer, difficulty in setting up of an auxiliary scaffold is lowered, scaffold climbing frequency is low, and accordingly personal safety of constructors can be guaranteed. Further, the mounting way is easy to control, manpower and material resources are saved, and operating efficiency is improved.
Description
technical field [0001] The invention relates to a method for installing nuclear power plant equipment, in particular to a method for installing a drum frame of a seawater circulating water drum-shaped filter screen. Background technique [0002] The seawater circulating water CRF system of the PX plant has 4 drum-shaped filter screens, and each drum-shaped screen screen includes a rotatable cylindrical drum skeleton. The drum frame is composed of main spokes, main beams, auxiliary beams, auxiliary spokes, circumferential connecting angle steel, mounting ring gear fixing grooves, large ring gears and side frames, etc. All components are connected by bolts. Two hubs on the main shaft to support. [0003] The installation method of the drum frame provided by the manufacturer is as follows: [0004] The first step is to assemble all the main spokes and their components separately (that is, to connect the main spokes and the main beam through bolts), and to assemble all the sub...
