Abstract
The invention discloses a lifting device for assembling a steam turbine reheat interceptor valve cover and a bush and relates to a lifting device, aiming at solving the problems that the process is complex and a workpiece interior structure is influenced by spot welding in a conventional lifting method. A cross bracket body comprises a connecting block and four cylindrical connecting rods, wherein the connecting block and the four cylindrical connecting rods form the cross bracket body; one ends of the four cylindrical connecting rods are fixedly connected with the connecting block into a whole; axes of the four cylindrical connecting rods are positioned on the same plane; the other end of each cylindrical connecting rod is in threaded connection with a capping nut; a nut cap of the capping nut is a cylinder; the lower end of a hook is fixedly arranged on the connecting block. The lifting device is used for assembling the steam turbine reheat interceptor valve cover and the bush.
Description
Technical field
The present invention relates to a kind of hanging apparatus, be specifically related to a kind of hanging apparatus for steam turbine reheat control valve valve gap and lining assembling.
Background technology
Steam turbine reheat control valve valve gap and lining interference connect joins, and lining need to be put into after liquid nitrogen shrinkage, reinstalls in valve gap, during lining normal temperature, between steam turbine reheat control valve valve gap and lining, is interference fit.
At present, the assembling of steam turbine reheat control valve valve gap and lining lifting adopts first spot welding hanger, then uses crane lifting hanger, finally hanger is cut off.
To sum up, existing hanging method needs welding, pincers worker reconditioning operation, exists complex process and spot welding meeting to impact to inside workpiece structure.
Summary of the invention
The problem that the present invention exists complex process and spot welding meeting to impact to inside workpiece structure for solving existing hanging method, and then a kind of hanging apparatus for steam turbine reheat control valve valve gap and lining assembling is provided.
The present invention solves the problems of the technologies described above the technical scheme of taking to be: the hanging apparatus for steam turbine reheat control valve valve gap and lining assembling of the present invention comprises hook, cross-shaped support body and four cover nuts, cross-shaped support body comprises contiguous block and four cylinder connecting rods, contiguous block and four cylinder connecting rods form cross-shaped support body, one end of four cylinder connecting rods all fixes as one with contiguous block, the axis of four cylinder connecting rods is with in one plane, the other end of every cylinder connecting rod has been threaded one and has covered nut, the nut cover of cover nut is cylinder, the lower end of hook is packed on contiguous block.
The invention has the beneficial effects as follows:
On the hanging apparatus assembling with lining for steam turbine reheat control valve valve gap of the present invention, four cover nuts are threaded with the outer end of cylinder connecting rod, lining upper inside wall is along the circumferential direction processed with flange, four cover nuts outwards screw out with the flange of lining inwall and overlap, compare with existing hanging method, lining steadily can be lifted and carries out liquid nitrogen cold-shrinkage, save the operation of welding and pincers worker reconditioning, simplified operation;
Hanging apparatus for the assembling of steam turbine reheat control valve valve gap and lining of the present invention is without spot welding hanger, the problem of having avoided spot welding to impact to inside workpiece structure;
The present invention also has advantages of simple in structure, low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the block diagram of the hanging apparatus for steam turbine reheat control valve valve gap and lining assembling of the present invention, the cutaway view of reheat control valve valve gap, lining and hanging apparatus when Fig. 2 is lining lifting.
The specific embodiment
The specific embodiment one: as shown in Fig. 1～2, the hanging apparatus for steam turbine reheat control valve valve gap and lining assembling of present embodiment comprises hook 1, cross-shaped support body 3 and four cover nuts 4, cross-shaped support body 3 comprises contiguous block 3-1 and four cylinder connecting rod 3-2, contiguous block 3-1 and four cylinder connecting rod 3-2 form cross-shaped support body 3, one end of four cylinder connecting rod 3-2 all fixes as one with contiguous block 3-1, the axis of four cylinder connecting rod 3-2 is with in one plane, the other end of every cylinder connecting rod 3-2 has been threaded one and has covered nut 4, the nut cover of cover nut 4 is cylinder, the lower end of hook 1 is packed on contiguous block 3-1.
During use, four cover nuts 4 are screwed in to contiguous block 3-1 direction separately, then hanging apparatus is put into lining endoporus, the hanging apparatus degree of depth is lower than the flange of lining, again four cover nuts 4 are outwards screwed out respectively, the top end face of four cover nuts 4 is contact bush inwall respectively, the top of four cover nuts 4 overlaps mutually with the flange of lining respectively, finally lining is steadily assembled in valve gap endoporus, after normal temperature, pull down hanging apparatus, lathe on valve gap and lining is machined away to the flange of lining endoporus and surplus to figure paper size.
The specific embodiment two: as shown in Figure 1, contiguous block 3-1's is shaped as cuboid described in present embodiment.So design, can guarantee four uniform surroundings that are arranged on contiguous block 3-1 of pipe link 3-2, and the angle between adjacent two pipe link 3-2 is 90o, lift so stressed evenly, hoisting process is steady.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: as shown in Figure 2, be processed with central through hole 3-1-1 on present embodiment contiguous block 3-1, the lower end of hook 1 is threaded with nut 2 through the central through hole 3-1-1 of contiguous block 3-1.So design, prevents that lifting rope from existing torsional deflection, and during lifting, lining produces rotation, links up with 1 rotation when screw thread connects, and lining can not rotate.Other composition and annexation are identical with the specific embodiment one or two.
