Technical field

The present invention relates to a kind of stator support tube assembly anti-deformation suspenders.

Background technique

During the preliminary assembly process of vertical machine stator, need for stator support tube to be packed into bore of stator, and be inserted into and determine Position seam allowance is limited, and stator support tube is thin wall cylinder-shaped workpiece, without suspension centre, so the assembly of large scale stator support tube is difficult Degree is big, is supported on stator support medial wall of the tube usually using mandril, and the frictional force between mandril and stator support tube is by stator Support tube, which is sling, completes assembly manipulation, but mandril be supported on stator support tube internal diameter two o'clock will cause stator support tube deformation, Lead to stator support tube dimension overproof, can not be packed into bore of stator seam allowance, later by improvement using circumference multi-point support Mode, although the deflection of stator support tube is reduced, since support sleeve barrel is relatively thin, problem on deformation is still serious.

Existing stator support tube fits through following manner realization: being supported on stator support medial wall of the tube using mandril, leans on Frictional force between mandril and stator support tube, which slings stator support tube, completes assembly manipulation, but mandril is supported on stator support The two o'clock of cylinder internal diameter will cause the deformation of stator support tube, leads to stator support tube dimension overproof, can not be packed into bore of stator seam allowance Interior, later by way of improveing using circumference multi-point support, but since support sleeve barrel is relatively thin, problem on deformation is still serious.

Summary of the invention

Goal of the invention of the invention is to provide a kind of stator support tube assembly anti-deformation suspender, can effectively solve the problem that stator Problem on deformation is lifted in support tube assembling process.The technical solution of the present invention is as follows: a kind of stator support tube assembly is hung with anti-deformation Tool, hinge seat 8 are weldingly fixed on 1 inner sidewall of steel ring, and steel ring 1 is equipped with an opening, and hinge seat 8 and hinge screw rod 4 pass through pin 9 Connection, long nut 5 are connected through a screw thread with hinge screw rod 4, are made of hinge seat 8, long nut 5, pin 9 and hinge screw rod 4 Mechanism is two sets, and Liang Tao mechanism is respectively positioned on 1 opening of steel ring and is parallel to each other, 1 outer circle adhesive rubber pad 6 of steel ring, Anti-fall Mechanism 3 is welded on 1 inner sidewall of steel ring.

The upper end support 3d and lower end support 3f of anti-falling mechanism 3 are welded on steel ring inner sidewall, and stock 3a passes through upper end Bushing 3b is welded in support 3d and the lower end hole support 3f, the upper end stock 3a, and pressure spring 3c is equipped between bushing 3b and upper end support 3d, Pressure spring 3c is mounted in the support counterbore of upper end, is compressed by bushing 3b and upper end support 3d, and baffle 3g is fixed using sunk screw In the lower end stock 3a.

Working principle of the present invention:

Present invention deficiency according to present in the above method improves, and is welded and fixed using steel ring 1 and hinge seat 8, hinge Chain seat 8 is connect with hinge screw rod 4 by pin 9, and long nut 5 is connected through a screw thread with hinge screw rod 4, and 1 outer circle of steel ring is bonded rubber Rubber mat 6, anti-falling mechanism 3 are welded on 1 inner sidewall of steel ring.The upper end support 3d and lower end support 3f of anti-falling mechanism 3 are welded On steel ring inner sidewall, stock 3a passes through upper end support 3d and the lower end hole support 3f, and welds bushing 3b in the upper end stock 3a, Pressure spring 3c is equipped between bushing 3b and upper end support 3d, the lower end stock 3a is fixed equipped with baffle 3g with sunk screw.

The course of work of the present invention:

By adjusting long nut 5, diminution 1 outer diameter of steel ring falls into suspender of the present invention in stator support tube 7, Long nut 5 is adjusted, 1 outer diameter of steel ring is amplified, 1 outer circle of steel ring patch, 6 surface of rubber pad is bonded with stator support tube 7, pushes And 90 ° of the handle 3e of rotary anti-falling mechanism, so that baffle 3g is slightly exceeded 6 outer round surface of rubber pad, keeps off at 7 end of stator support tube At face, stator support tube 7 is sling using lifting lug 2, is fallen into bore of stator, baffle 3g will be contacted with the seam allowance end face of bore of stator Before, it pushes handle 3e and is rotated by 90 ° handle 3e, baffle 3g is stuck in the support 3f groove of lower end by rotating, by stator branch After supportting the lifting in place of cylinder 7, long nut 5 is adjusted, 1 outer circle of steel ring is reduced to having obvious gap with stator support tube 7, stator is supported Cylinder 7 assembles suspender and hangs out, and so far completes 7 assembling process of stator support tube.

The advantageous effects that the present invention has:

1, it is bonded by the rubber pad 6 of 1 outer circle of steel ring with 7 inner sidewall of stator support tube and generates frictional force lifting stator support Cylinder 7,7 uniform force of stator support tube, deflection is small during lifting, does not influence to assemble.

2, it is equipped with anti-falling mechanism 3, unexpected the case where falling off is prevented in 7 hoisting process of stator support tube, increases suspender Safety.

The present invention is bonded by way of 1 uniform shrinkage outer diameter of steel ring with stator support tube 7, and forced area is big, to steel ring 1 Support force request it is small, and uniform force, the very deformation for reducing stator support tube 7 and being generated in assembling process of limits Amount.
