Abstract
The invention discloses an integral hoisting method of a distributor of a bulb tubular hydraulic generator unit. Four hoisting points are arranged on the distributor of the bulb tubular hydraulic generator unit. After the upper-end hoisting points and the lower-end hoisting points on the same side are connected in series through steel wire ropes, the steel wire ropes are hung on a hook of a hoisting device, the hoisting device is started, and the distributor is hoisted and installed. By hanging the steel wire ropes at both ends of the hook after the hoisting points on the same side are connected in series respectively through the steel wire ropes, during a hoisting process, along with the changes of the hoisting height of the distributor of the bulb tubular hydraulic generator unit, the steel wire ropes slide on the hook for regulation to enable the distributor of the bulb tubular hydraulic generator unit to be always in a relatively stable state so as to prevent the distributor of the bulb tubular hydraulic generator unit from turning to the side. The integral hoisting method of the distributor of the bulb tubular hydraulic generator unit is suitable for hoisting of the distributor of the bulb tubular hydraulic generator unit.
Description
Technical field
The present invention relates to a kind of scaled bulb tubular hydraulic generator group water distributor integral hoisting method.
Background technology
12 meters of the water distributor diameters of super large type light bulb through-flow type hydro-turbo generator set, high 2.8 meters, 195 tons of hoisting weights, water distributor generally comprise inner pivot ring and outer lead ring.The installation of water distributor need be stood up it, and it is vertically hung in the foundation ditch installs.Water distributor stands up general employing two main suspension centre body turning methods.This two main suspension centre body turning method refers to, and two free bearings is arranged in the attachment face in the outer lead ring of water distributor, and on the sidewall surfaces on a twisted seat opposite, is provided with two suspension centres; Two suspension centres are near the upper surface of water distributor, connect suspension centre with an end of steel rope after, the other end is connected with suspender; With suspender with water distributor sling come after; Because two main suspension centres on the water distributor receive connecting lever stroke limitation and deviation of gravity center bigger, eccentric weight moment will cause water distributor tumble and impulsive force bigger, should not below water distributor, support overcome impulsive force temporarily; And after water distributor stood up, the flange face squareness can not be adjusted.When water distributor stood up, the suffered impulsive force of steel rope was not easy to calculate, and can't guarantee safety.
Summary of the invention
The technical matters that the present invention will solve provides a kind of scaled bulb tubular hydraulic generator group water distributor integral hoisting method.
The technical solution adopted for the present invention to solve the technical problems is: a kind of scaled bulb tubular hydraulic generator group water distributor integral hoisting method comprises the steps:
1) at water distributor one side-lower two twisted seats are set, and water distributor is hinged with a twisted seat;
2) prop up twisted seat the left and right sides of right water distributor sidewall be provided with upper end suspension centre and lower end suspension centre, after with steel rope the upper end suspension centre of homonymy and lower end suspension centre being connected respectively, steel rope hangs over the hook two ends of hanging device;
3) water distributor is sling and overturn 90 ° with hanging device, remove a twisted seat;
4) installation O RunddichtringO on the inner pivot ring of water distributor and outer lead ring;
5) after vertically lifting up into water distributor in the foundation ditch, inner pivot ring is connected with the cast seat;
6) leak tightness and the right alignment between inspection inner pivot ring and cast seat.
Further as the improvement of technical scheme of the present invention, in step 1), said twisted seat is symmetrically distributed in the water distributor below.
Further as the improvement of technical scheme of the present invention, in step 2) in, the upper end suspension centre is symmetrically distributed, and the lower end suspension centre is symmetrically distributed.
Further as the improvement of technical scheme of the present invention, in step 2) or step 3) in, said hanging device is transfer crane or crane in bridge type.
Further, in step 5), hauling rope is set in the water distributor both sides as the improvement of technical scheme of the present invention.
Beneficial effect of the present invention: among the present invention through after respectively the suspension centre of homonymy being together in series with steel rope; Steel rope hangs over the two ends of suspension hook; In the lifting process, along with the variation of scaled bulb tubular hydraulic generator group water distributor height of lift, steel rope is slide control on suspension hook; Make scaled bulb tubular hydraulic generator group water distributor be in relative pulsation-free state always, prevent that the rollover phenomenon from appearring in scaled bulb tubular hydraulic generator group water distributor.
The present invention is applicable in the lifting of scaled bulb tubular hydraulic generator group water distributor.

Fig. 3 is the scheme drawing of scaled bulb tubular hydraulic generator group water distributor of the present invention when slinging state.
The specific embodiment
Referring to figs. 1 through Fig. 3, a kind of scaled bulb tubular hydraulic generator group water distributor integral hoisting method comprises the steps:
1) at water distributor 1 one side-lowers two twisted seats 4 are set, and water distributor 1 is hinged with a twisted seat 4;
2) prop up twisted seat 4 the left and right sides of right water distributor 1 sidewall be provided with upper end suspension centre 5 and lower end suspension centre 7, after with steel rope 8 the upper end suspension centre 5 of homonymy being connected with lower end suspension centre 7 respectively, steel rope 8 hangs over the hook two ends of hanging device 6;
3) with hanging device 6 90 ° are sling and overturn to water distributor 1, remove a twisted seat 4;
4) installation O RunddichtringO on the inner pivot ring of water distributor 3 and outer lead ring 2;
5) after vertically lifting up into water distributor 1 in the foundation ditch, inner pivot ring 3 is connected with the cast seat;
6) leak tightness and the right alignment between inspection inner pivot ring 3 and cast seat.
As the preferred embodiment of the present invention, in step 1), said twisted seat 4 is symmetrically distributed in the water distributor below.
