Abstract
The utility model relates to a guide vane assembly and lifting tooling for a water turbine generator set, which is characterized by comprising a spiral pull rod, wherein a pull hook is arranged at one end of the spiral pull rod, a threaded rod is arranged at the other end of the spiral pull rod, a nut is mounted on the threaded rod of the spiral pull rod, the spiral pull rod is connected with a clamp body with a through hole, the pull hook of the spiral pull rod and the nut mounted on the threaded rod are respectively positioned on two sides of the through hole, and a lifting lug pressure rod is hinged on the clamp body. Compared with the prior art which adopts a steel wire rope to wind and lift a guide vane body, the guide vane assembly and lifting tooling has the advantages of simple structure and high assembly efficiency, is convenient to use, and can reduce the production cost and the like.
Description
Technical field
The utility model belongs to hydraulic generator unit erector packing technique field, particularly relates to a kind of hydraulic generator unit stator assembling lifting frock.
Background technology
At present, diffuser is the important composition parts of hydraulic generator unit, in the prior art, diffuser generally twines lifting by steel rope finishes installation, adopts steel rope that diffuser is lifted the center of gravity that need at first determine diffuser, can not produce the phenomenon that skew is fallen to guarantee diffuser in the process of lifting, the center of gravity of determining diffuser needs operating personal repeatedly to adjust repeatedly, this process operation is wasted time and energy, and has a strong impact on the installation rate of diffuser, inefficiency.The waterside that goes out of diffuser has sharp cutting edge, and the weight of each diffuser is often above 1 ton, in the hoisting process of diffuser, the steel rope that is used to twine the lifting diffuser is very easily cut off by the sharp cutting edge of diffuser, thereby causes the diffuser damage of falling, and the steel rope consumption is big, make the productive costs of hydraulic generator unit increase, in addition, hurt sb.'s feelings if become the heavy diffuser of ton in hoisting process, to drop, then can produce serious consequence, potential safety hazard is high.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, easy to use, can enhance productivity, reduce production costs, and the hydraulic generator unit stator that can effectively eliminate safe hidden trouble assembling lifting frock.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is: a kind of hydraulic generator unit stator assembling lifting frock, it is characterized in that: comprise that an end is provided with the spiral pull bar of drag hook, the other end of spiral pull bar is a thread rod, on the thread rod of spiral pull bar nut is installed, the spiral pull bar is connected with the clamp body that has through hole, and the drag hook of spiral pull bar and be installed in the both sides that nut on the thread rod lays respectively at through hole is hinged with the hanger depression bar on the clamp body.
The utility model can also adopt following technical scheme: described clamp body comprises pull bar connecting portion and hanger connecting portion, constitutes the hook groove between pull bar connecting portion and the hanger connecting portion.
One end of described hanger depression bar is provided with lifting hole(eyelet), and the other end is a globoidal structure.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, comprise that promptly an end is provided with the spiral pull bar of drag hook, the other end of spiral pull bar is the thread rod that nut is housed, the spiral pull bar is connected with the clamp body that has through hole, and the drag hook of spiral pull bar and be installed in the both sides that nut on the thread rod lays respectively at through hole is hinged with the hanger depression bar on the clamp body.When the hydraulic generator unit stator of said structure assembling lifting frock is used, diffuser is fixed, in the hoisting process, can be played the effect of self-locking to diffuser with clamp body bonded assembly hanger depression bar by the nut that screws on the thread rod.Compared to existing technology, advantage such as that frock described in the utility model has is simple in structure, easy to use, efficiency of assembling is high, can reduce production costs, and prevent that effectively diffuser drops in the hoisting process, eliminated potential safety hazard.One end of hanger depression bar is provided with lifting hole(eyelet), and the other end is a globoidal structure, and globoidal structure contacts with diffuser, can prevent that the hanger depression bar from scratching diffuser.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the birds-eye view of Fig. 1.
Among the figure: 1, spiral pull bar; 1-1, drag hook; 1-2, thread rod; 2, clamp body; 2-1, hanger connecting portion; 2-2, pull bar connecting portion; 2-3, hook groove; 3, hanger depression bar; 3-1, lifting hole(eyelet); 4, diffuser; 5, nut; 6, pin.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1 and Fig. 2, a kind of hydraulic generator unit stator assembling lifting frock, comprise spiral pull bar 1, one end of described spiral pull bar 1 is drag hook 1-1, the other end of spiral pull bar 1 is thread rod 1-2, nut 5 is installed on the thread rod 1-2, spiral pull bar 1 is connected with clamp body 2, described clamp body 2 comprises pull bar connecting portion 2-2 and hanger connecting portion 2-1, form hook groove 2-3 between pull bar connecting portion 2-2 and the hanger connecting portion 2-1, pull bar connecting portion 2-2 is provided with through hole, spiral pull bar 1 passes through through hole, and the drag hook 1-1 of spiral pull bar 1 and be installed in the both sides that nut 5 on the thread rod 1-2 lays respectively at through hole, to realize being connected of spiral pull bar 1 and clamp body 2, hanger connecting portion 2-1 is hinged with hanger depression bar 3 by pin 6, one end of hanger depression bar 3 is provided with lifting hole(eyelet) 3-1, the other end is a globoidal structure, can prevent that hanger depression bar 3 from scratching diffuser 4 in the process of lifting self-locking.
Principle of work frock described in the utility model in use, at first diffuser 4 is placed between the hook groove 2-3 of the drag hook 1-1 of spiral pull bar 1 and clamp body 2, and the cutting edge of diffuser 4 is positioned at drag hook 1-1 one side, adjust diffuser 4 behind suitable position, screw the nut 5 on the thread rod 1-2, diffuser 4 is fixed on the frock, operating personal can be sling frock by hanger depression bar 3, in the process of diffuser 4 liftings, it is the lever of fulcrum that hanger depression bar 3 forms with pin 6, thereby the deadweight by diffuser 4 realizes self-locking, prevented that effectively diffuser 4 drops in the hoisting process, in addition, hanger depression bar 3 is made as the arc surface structure with diffuser 4 contact jaws, can avoid hanger depression bar 3 to scratch diffuser 4.Above-mentioned frock is compared with available technology adopting steel rope winding lifting diffuser, has advantages such as simple in structure, easy to use, that efficiency of assembling is high, can reduce production costs.
