It is equipped with suspension hook；Driving suspension centre 4 is provided with the middle part of lifting shoulder pole, driving suspension centre 4 is by the suspension hook on the first steel wire rope and driving
Connection, the first steel wire rope has enough length, when making the lift hook position of driving higher than cross over pipe top, lifts by crane the position of shoulder pole 5
Set low in the bottom of cross over pipe；
The effect of the 3rd steel wire rope 2 be will lifting shoulder pole 5 transfer to the lower section of cross over pipe, its one end extend to bearing block and
The surface of bearing shell, by way of vertical lifting, when solving inclination lifting, playing hanging object 1 can produce certain horizontal velocity,
The problem of certain potential safety hazard can be produced to neighbouring people or thing.
Counterweight 6 is connected by the second steel wire rope with one end of lifting shoulder pole 5, and the opposite side for lifting by crane shoulder pole 5 is connected with the 3rd
Steel wire rope 2, the distance between suspension centre and driving suspension centre 4 of the 3rd steel wire rope 2 on lifting shoulder pole 5 is more than or equal to the half of cross over pipe
Footpath.The effect of counterweight 6 herein is to provide downward active force, using lever principle, will play hanging object 1 vacantly, is easy to conveying.
Lifting shoulder pole 5 is hung in the lower section of driving by the first steel wire rope, due to the length long enough of the first steel wire rope so that
At the top of cross over pipe, the position for lifting by crane shoulder pole 5 may be located at the lower section of cross over pipe to suspension hook, because lifting shoulder pole 5 has necessarily
Length, so, can will lifting shoulder pole 5 rotate, the one end of the 3rd steel wire rope 2 that is connected with of lifting shoulder pole 5 is extended to UNICOM
The lower section of pipe, and the bearing block dismantled and bearing shell (playing hanging object 1) are hung on the 3rd steel wire rope 2, just can be without removing connection
In the case of siphunculus, the bearing block and bearing shell of dismounting are lifted, greatlyd save the cost of overhaul of bearing shell.
Several fixture blocks 3 are preferred embodiment evenly equipped with the lifting shoulder pole 5 as a kind of, the protrusion of fixture block 3 is lifted by crane
The body of shoulder pole 4 is set, and the second steel wire rope and the 3rd steel wire rope 2 are respectively positioned on two adjacent fixture blocks 3 with the tie point of lifting shoulder pole 5
Between.
As the alternative of above-mentioned implementation method, uniform several grooves on lifting shoulder pole 5, the second steel wire rope and the
One end system of three steel wire ropes closes in a groove, and groove can not only be defined to the hoisting point position of steel wire rope, can also be effectively
Steel wire rope is prevented along the slip of lifting shoulder pole 5, it is to avoid caused danger during lifting.
Due to fixture block 3 lifting shoulder pole 5 on be equally distributed, so the position of fixture block 3 can substantially show lifting
The position of shoulder pole 5, according to the weight and the weight of counterweight 6 that play hanging object 1, you can determine the second steel wire rope and the 3rd steel wire rope 2
Suspension centre, be more convenient operation.Fixture block 3 can also carry out steel wire rope spacing, prevent steel wire rope (including the second steel wire rope and the 3rd
Steel wire rope) along the slip of lifting shoulder pole 5, it is ensured that the stabilization of hoisting process, it is to avoid cause danger.
Preferably, lifting shoulder pole 5 is prepared from by I-steel, and I-steel has intensity higher, without special processing,
Simple structure.Or lifting shoulder pole 5 is integrally formed in a mold with fixture block 3.
The method that hoisting special purpose tools are lifted by crane is checked using above-mentioned turbine generator unit shaft watt, is comprised the following steps：
1) will lift by crane shoulder pole 5 in driving suspension centre 4 by the first wire rope suspensioning driving suspension hook on；
2) driving will be lifted by crane at the cross over pipe that shoulder pole 5 is transported at bearing block to be removed, the first steel wire rope is located at UNICOM
The side of pipe, and set against cross over pipe, the position of shoulder pole is lifted by crane in the top of the suspension hook position higher than cross over pipe of driving
Less than the bottom of cross over pipe；
3) rotation lifting shoulder pole 5 (due to lifting shoulder pole 5 by the first steel wire rope be in suspended state, can be by manpower
Directly the mode of rotation lifting shoulder pole 5 is carried out, it is also possible to lifting shoulder pole 5 is rotated by external force), make lifting shoulder pole 5
The one end for connecting the 3rd steel wire rope 2 extends into the lower section of cross over pipe, and positioned at the top of bearing block to be removed；
4) bearing block or/and bearing shell of dismounting are lifted on the lower end of the 3rd steel wire rope 2；Adjust the suspension centre of the second steel wire rope
Position on lifting shoulder pole 5, after adjusting, lifts counterweight 6, in the leverage of counterweight 6 in the lower end of the second steel wire rope
Under, make the bearing block of lifting or/and bearing shell hanging；Herein hanging refers to leave supporter, to hanging height without it is special will
Ask, i.e., need not require that the flying height of hanging object 1 is equal with the flying height of counterweight 6, it is preferable that when playing hanging object 1 and being hanging, rise
Hang shoulder pole 5 and be in horizontality.
5) start driving, bearing block or/and bearing shell be transported to maintenance department, due to now lifting shoulder pole 5 top
Through the limitation without cross over pipe, driving can be lifted by crane upwards, and bearing block and bearing shell are placed on inspection rack.
One phase of table mountain Second Power Plant, 2 × 1000MW units engineering #1 units, steam turbine is had by Harbin Turbine
Limit company and Toshiba Corp's co-design and the national First pattern of production be overcritical, resuperheat, single shaft,
Four cylinders, four steam discharges, condensing turbine；During the test run of unit 168, find #3, #4 bearing bush temperature it is high, unit by forced-stopping machine,
Be pressed for time, task weight, through test run headquarter discuss need to assault repairing check bearing shell, due to bearing shell be located at communicating pipe immediately below, profit
Lifting is carried out to bearing shell with driving and checks that service work cannot be realized, and remove cross over pipe, additional workload certainly will be increased；Herein
In the case of, absorbed all the useful ideas at steam turbine construction, using existence conditions, bearing shell hoisting special purpose tools are designed and produced, smoothly complete
To inspecting bearing shell repairing work.
Although above-mentioned be described with reference to accompanying drawing to specific embodiment of the present utility model, not to utility model
The limitation of protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, this area
Various modifications or deform still in protection domain of the present utility model that technical staff makes by need not paying creative work
It is interior.
