Abstract
The utility model relates to a combined hoisting apparatus for a high/medium/low-pressure cylinder of a turbine, which has a simple structure, is convenient to install, saves cost, and shortens the total assembly cycle, the field installation cycle and the repair cycle of the turbine. The structure of the combined hoisting apparatus comprises two long steel wire rope, four short steel wire ropes and two chain blocks matched with the short steel wire ropes, wherein one ends of the two long steel wire ropes are connected with a lifting hook, the other ends of the two long steel wire ropes are connected with connecting lugs at two sides of the rear end of the cylinder; one ends of two short steel wire ropes are connected with the hook, and the other ends of the two short steel wire ropes are respectively connected with the chain blocks; and one ends of the remaining two short steel wire ropes are respectively connected with the chain block, and the other ends of the remaining two short steel wire ropes are respectively with two sides of the front end of the cylinder.
Description
Technical field
The utility model relates to a kind of lifting appliance, and the high, medium and low cylinder pressure of especially a kind of steam turbine is united the equipment of lifting.
Background technology
When at present general steam turbine is installed in workshop and in the erecting stage high, medium and low cylinder pressure first when installing, must carry out dismounting repeatedly.It not only wastes the workshop final assembly lead time greatly, increased the field erected cycle of power plant steam turbine, in first repeated disassembled and assembled process of high, medium and low cylinder pressure, tie bolt can be damaged, reduce the service life of tie bolt, and the whole maintenance during to the steam turbine overhaul is opened the cylinder process and is caused unnecessary trouble.
The utility model content
The utility model is for overcoming above-mentioned the deficiencies in the prior art, provide a kind of high, medium and low cylinder pressure of steam turbine simple in structure, easy for installation to unite the equipment of lifting, it has saved cost, has shortened the steam turbine general-assembling cycle, has shortened steam turbine on-site installation cycle and period of inspection and repair.
The purpose of this utility model is to adopt following technical proposals to realize:
The high, medium and low cylinder pressure of a kind of steam turbine is united the equipment of lifting, it comprises two long steel ropes, 4 straps and two chain blocks that match with strap, described two long steel rope one ends are connected with suspension hook, and the other end is connected with the hanger of both sides, cylinder rear end respectively; Two one ends in the described strap are connected with suspension hook, and the other end is connected with chain block respectively, and an end of two straps of residue is connected with chain block respectively, and the other end is connected with cylinder front end both sides respectively.
The utility model is made adjustment to the length of 4 straps in use by the hand adjustment chain block, thereby finds the center of gravity of high, medium and low cylinder pressure and cylinder to reach the lifting purpose.
The utility model utilization is simple and easy to purchase, the easy-to-operate chain block, and M/C just can reach accurate adjustment length of steel wire rope, thereby is easy to find the center of gravity of steam turbine and cylinder to lift by crane.
The beneficial effects of the utility model are: provide a kind of simple in structure, easy for installation, avoided steam turbine in workshop, when install the erecting stage and when the steam turbine overhaul is overhauled, must carry out dismounting repeatedly.Reduce the waste of manpower and materials, shortened the steam turbine general-assembling cycle, shortened steam turbine on-site installation cycle and period of inspection and repair.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the left view of Fig. 1.
1. long steel ropes wherein, 2. strap, 3.. chain block, 4. cylinder.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Among Fig. 1, Fig. 2, it comprises 1,4 straps 2 of two long steel ropes and two chain blocks 3 that match with strap 2, and described two long steel rope 1 one ends are connected with suspension hook, and the other end is connected with the hanger of both sides, cylinder 4 rear end respectively; Two one ends in the described strap 2 are connected with suspension hook, and the other end is connected with chain block 3 respectively, and an end of two straps 2 of residue is connected with chain block 3 respectively, and the other end is connected with cylinder 4 front end both sides respectively.
Before the lifting, the length of hand adjustment chain block 3, thus range estimation reaches center of gravity and hook in-line.Distance element is lifted by crane, thereby the connector of long steel rope 1 and strap 2, chain block 3 is all strained.Find that the prestress of which root steel rope is less this moment, not tension just, and hand adjustment chain block 3 makes its tension.Adjust the back repeatedly several times and just can make whole cylinder integral lifting, this device effect is very desirable in actual applications.
