Description
Technical field:
The utility model relates to core main pump pump shaft lifting devices.
Background technique:
Core main pump pump shaft lifting device is one of key tool in main pump shaft system installing and dismounting maintenance process, directly affects core
Main pump installation.Lifting device and matched centering tool, easy shaft component is not used in incorrect installation process or installation process
It damages, and then influences the duration or directly contribute economic loss.Since conventional lift tool is directly to lift by crane, mentioned compared to tradition
Rise tool, the tool construction is simpler, and required space is smaller, and due to its for threaded engagement promoted and lock, controllable precision compared with
It is high, it is ensured that lifting component safety is needed in installation process.
Summary of the invention:
The purpose of this utility model is that open one kind is simple in construction, easy to disassemble and assemble, and core main pump pump shaft applied widely mentions
Rise device.The technical solution of the utility model is: a seed nucleus main pump pump shaft lifting device, and screw rod (1) is elongate threaded screw, screw rod
(1) with lifting component using being threadedly engaged, the other end and fixation member clearance fit of screw rod (1), screw sheel (3) are outer spiral shell
Line sleeve, screw sheel (3) one end is equipped by external screw thread and sleeve (4), and sleeve (2) and screw sheel (3) inner hole are equipped, set
Cylinder (2) upper surface and nut (6) are equipped, and sleeve (2) lower part and bearing (5) are equipped.
Utility model works principle:
As shown in Figure 1, core main pump pump shaft lifting device work when, make screw up with a wrench screw sheel (3), by with (2)
Between cooperation, power is passed to sleeve (4) by thrust bearing (5), the effect between sleeve (4) and detachable-shaft (7) can be real
The promotion of existing pump shaft (8), nut (6) can be used for locking；The design feature of the utility model is contact, and screw rod and shaft coupling are logical
It crosses and is threadedly engaged, be clearance fit with detachable-shaft, power is passed to by sleeve by detachable-shaft by thrust bearing when sleeve is tightened,
The final promotion for realizing pump shaft.The utility model can be used for the promotion of different heap-type core main pump pump shaft installing and dismounting processes.
The beneficial effects of the utility model are:
(1) the utility model is made of sleeve, bearing and screw rod, by screw thread or thrust bearing transmission force, realizes pump shaft
Promotion, due to be threadedly coupled, bearing transmission force, thus simple and reliable for structure, and better economy；
(2) in structure, the quick detachable maintenance of the device avoids main pump component instead of the components stress such as bolt in main pump
Damage.
The utility model, it is convenient for disassembly and assembly, it is applied widely, it can be used for different heap-type core main pump pump shaft installing and dismountings, and just
Reliable for operation in maintenance, safe handling degree is high.
Detailed description of the invention
Fig. 1 is that core main pump pump shaft lifting device installs and uses installation diagram
Fig. 2 is core main pump pump shaft lifting device cross-sectional view
Specific embodiment:
As shown in Fig. 2, a seed nucleus main pump pump shaft lifting device, screw rod 1 is elongate threaded screw, and screw rod 1 and lifting component use
It is threadedly engaged, the other end and fixation member clearance fit of screw rod 1, screw sheel 3 are external thread sleeve, 3 one end of screw sheel
Equipped by external screw thread and sleeve 4, sleeve 2 and 3 inner hole of screw sheel are equipped, and 2 upper surface of sleeve and nut 6 are equipped, under sleeve 2
Portion and bearing 5 are equipped.
