Technical field
The utility model relates to the device that is used to overhaul turbine rotor, more particularly, relates to a kind of special stand that is used to overhaul turbine rotor.
Background technology
At present, the existing special stand volume that is used to overhaul turbine rotor is big, and deal is heavy, and floor space is bigger, and it is poor to support stationarity, handles complicatedly, and roller is prone to injure rotor journal, need add to try to give a false impression a watt sheath.The defective value of said prior art must improve.
The utility model content
The purpose of the utility model is a kind of special stand that is used to overhaul steam turbine to be provided to above-mentioned technological deficiency, and this is used to overhaul the special stand of steam turbine, and not only volume is little, and is in light weight and need not to add and try to give a false impression a watt sheath, do not injure rotor journal.
The technical scheme of the utility model is described below: a kind of special stand that is used to overhaul turbine rotor; Comprise the seat of honour with following, it is characterized in that a said following upper surface is embedded with the concave spherical surface structural member; The said seat of honour with following on the concave spherical surface structural member that is embedded be connected through connecting axle; Said connecting axle two ends are respectively fitted with round nut one and round nut two, are provided with round nut between the said round nut one and the seat of honour and use the stop back-up ring, and this round nut is with the stop back-up ring and be sheathed on the connecting axle; Be arranged with protruding spherical structure spare on the said connecting axle, this protruding spherical structure spare be located at the seat of honour with following between and be connected with concave spherical surface structural member assembling.
According to the utility model of said structure, its characteristic is that also said concave spherical surface structural member is connected through bolt with following.
According to the utility model of said structure, its characteristic is that also said round nut is with being provided with plain washer between the stop back-up ring and the seat of honour, and this plain washer also is sheathed on the connecting axle.
According to the utility model of said structure, its characteristic also is, is provided with spheric washer and taper faced washer between said concave spherical surface structural member and the round nut two, and this spheric washer is located on the taper faced washer and is sheathed on the connecting axle.
According to the utility model of said structure, its beneficial effect is: the utility model volume is little, and is in light weight, and floor space is little, shelves simply, supports steady safety, handiness.
Description of drawings
Fig. 1 is the utility model master TV structure sketch map;
Fig. 2 is the utility model sectional structure sketch map.
In the drawings: 1, the seat of honour; 2, following; 3, round nut one; 4, round nut is used stop washer; 5, plain washer; 6, protruding spherical structure spare; 7, concave spherical surface structural member; 8, spheric washer; 9, taper faced washer; 10, connecting axle; 11, round nut two.
The specific embodiment
Below in conjunction with embodiment the present invention is further described:
Like Fig. 1, shown in Figure 2; A kind of special stand that is used to overhaul turbine rotor, comprise the seat of honour 1 with following 2, it is characterized in that; Said following 2 upper surfaces are embedded with concave spherical surface structural member 7; Said concave spherical surface structural member 7 is connected through bolt with following 2, the said seat of honour 1 with following 2 on the concave spherical surface structural member 7 that is embedded be connected through connecting axle 10, said connecting axle 10 two ends are respectively fitted with round nut 1 and round nut 2 11; Be provided with round nut with stop back-up ring 4 between the said round nut 1 and the seat of honour 1; This round nut is with stop back-up ring 4 and be sheathed on the connecting axle 10, and said round nut is with being provided with plain washer 5 between the stop back-up ring 4 and the seat of honour 1, and this plain washer 5 also is sheathed on the connecting axle 10; Be arranged with protruding spherical structure spare 6 on the said connecting axle 10; This protruding spherical structure spare 6 be located at the seat of honour 1 with following 2 between and is connected with concave spherical surface structural member 7 assembling, be provided with spheric washer 8 and taper faced washer 9 between said concave spherical surface structural member 7 and the round nut 2 11, this spheric washer 8 is located on the taper faced washer 9 and is sheathed on the connecting axle 10.
The utility model adopts case type closed design, more reasonable structure, stable.It is inner that four lower margin guiding mechanisms are completely enclosed within the box base, and lower margin has increased the protection wing plate, occurs when unusual at leading screw, and wing plate props up on the ground, and generation can not cause the accident.On the body horizonal base plate, install level meter additional, before depositing rotor, the adjustment entire bracket makes support vertically stressed, increases the stability of support, and storage bracket is more reliable.
The utility model adopts idler structure, and the carrying roller overcoat is selected brass material for use, adopts the centrifugal casting mode to cast, and material brass hardness is little, when contacting with rotor, avoids damaging rotor.Carrying roller adopts four carrying rollers swing aligning structure, and carrying roller rotates around swinging axle for two one group, and when rotor was placed on the support carrying roller, the carrying roller swing all contacted closely four carrying rollers with the rotor supports position, increase contact rate, avoids damaging rotor.Universal globe self-regulated core structure is adopted in the coupling part of roller seat and base; Roller seat can be swung, when because the placement location error, when rotor axis and carrying roller axle center are not parallel arbitrarily; Rotor is placed in the process on the support sphere self-regulated core structure and swings automatically; Guarantee that rotor contacts with the carrying roller retention wire all the time, increase contact rate, contact rate reaches more than 98%.Install sliding panel additional between roller seat and the base, roller seat can be along the adjustment of rotor axial direction, and adjusting range is 60mm, when two rotor field spiders placement distance has error, can make placement location best through axially adjustment adjusting.Avoided moving of entire bracket once more, saved time, the convenient use.Two groups of carrying rollers can be in the radial direction adjustment of rotor, in the adjusting range position of the different diameters of axle of support rotor arbitrarily, makes support force the best, makes things convenient for the maintenance of rotor.
The utility model supporting leg also adopts the box-structure design, and four lower margin guiding mechanisms adopt the complete closed design, and the height-adjustable scope is 100mm, and on the basis of proof strength and rigidity, integral body is more attractive in appearance.
