Description
Technical field
The utility model relates to a kind of lifting tool, especially relates to a kind of used in nuclear power station and lifts axial organ.
Background technology
At present, the rotating machinery maintenance of the nuclear station rotor inspection bearing of need slinging generally adopts driving to hang or adopts the method for jack that the equipment rotor is raise, and then overhauls.More than the shortcoming of two kinds of methods be: the former need take driving for a long time, reduces the driving Occupation coefficient; The latter will have the space of placing jack, because jack is little with the contact point of axle, stability and safety are bad.
The utility model content
The purpose of the utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of range of use wide, safe and reliable, with low cost, overhaul easily used in nuclear power station and lift axial organ.
The purpose of the utility model can realize through following technical scheme: a kind of used in nuclear power station is lifted axial organ, it is characterized in that, this is lifted axial organ and comprises carrier ring, carriage and jacking screw; Described carrier ring comprises the first arc body and two first support ears; Two first support ears are connected to the first arc body two ends, and described carriage is located at the carrier ring top, and this carriage comprises the second arc body and two second support ears; The second arc body and first this body profile of arc are complementary; Described two second support ears are connected to the second arc body two ends, and two second support ears are provided with tapped through hole, and jacking screw is located in the tapped through hole.
The cambered surface of the described first arc body is the semicircle cambered surface, and the cambered surface of the second arc body is the semicircle cambered surface.
Compared with prior art, the utlity model has following advantage:
1, range of use is wide: the novel axial organ of lifting can be selected carbon steel material for use, be applicable to rotor weight be lower than 10 tons all rotating machinerys lift axle operation, can be according to the intensity of the weight design carriage of rotor.
2, safe and reliable: novel to lift axial organ sturdy and durable, and safety performance is high, good reliability.
3, with low cost: the novel axial organ of lifting is made with general carbon steel, but repeated use with low cost.
4, maintenance is convenient: novel to lift axial organ easy to use, need not training.
Description of drawings
Fig. 1 is the running condition figure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of used in nuclear power station is lifted axial organ, and this is lifted axial organ and comprises carrier ring 1, carriage 2 and jacking screw 3.Carrier ring 1 comprises that the first arc body 11 and 12, two first support ears 12 of two first support ears are connected to the first arc body, 11 two ends.Carriage 2 is located at carrier ring 1 top; This carriage 2 comprises the second arc body 21 and two second support ears 22; The second arc body 21 and the first arc body, 11 profiles are complementary; Two second support ears 22 are connected to the second arc body, 21 two ends, and two second support ears 22 are provided with tapped through hole, and jacking screw 3 is located in the tapped through hole.The cambered surface of the first arc body is the semicircle cambered surface, and the cambered surface of the second arc body is the semicircle cambered surface.
When axial organ is lifted in use; Utilize the bolt hole fixing branch carrier ring 1 of former bear box lubriplate; Two support ears 12 of carrier ring 1 are placed on the horizontal joint of bear box; Rotor 4 with carriage 2 pockets and be placed on directly over the carrier ring 1, the high level of synchronization of lifting according to rotor 4 needs two jacking screws 3 of screwing utilize the principle jack-up rotor 4 of lifting screw.
Claims (2)
