Description

Vertical derivation cooler maintenance platform of large-scale hydroelectric set

Technical Field

The utility model belongs to hydraulic generator overhauls the equipment field, in particular to vertical derivation cooler of large-scale hydroelectric set overhauls platform.

Background

The derivation bearing cooler of the large umbrella type hydroelectric generating set is hung on the side surface of a support arm of a lower rack of a waterwheel chamber of the unit, the cooler is vertically installed, and the distance between the lower water tank cover of the cooler and the upper surface of a control ring is higher than the normal maintenance height of a maintainer. Therefore, when the lower water tank of the cooler is sealed or the water tank is cleaned, a maintainer has certain operation risk and maintenance difficulty, and the efficiency is very low.

Disclosure of Invention

The utility model aims to solve the technical problem that a vertical derivation cooler of large-scale hydroelectric set overhauls platform is provided, easy dismounting can improve cooler water tank maintenance efficiency greatly, reduces at the maintainer in cooler water tank maintenance in-process, latent maintenance operation risk.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a vertical derivation cooler of large-scale hydroelectric set overhauls platform, includes the platform, is equipped with the guardrail on the platform, and guardrail one side is equipped with the entry, and the entry is equipped with the peg, and one side that the peg was kept away from to the platform is equipped with the locking link plate, and locking link plate bottom is equipped with the locking bolt of tight in the control ring bottom in the top, still includes the staircase, and the upper end of staircase is equipped with the couple, and the couple is hung and is established on the peg.

In the preferred scheme, a jacking plate is arranged on the platform close to the side of the hanging shaft, and a jacking wire which is tightly jacked on the inner side of the control ring is arranged on the jacking plate.

In a preferred scheme, a plurality of supporting legs supported on the control ring are arranged at the bottom of the platform.

In a further scheme, the bottom of the supporting leg is provided with a non-slip mat.

In a further scheme, the supporting legs are provided with external threads, and threaded holes matched with the supporting legs are formed in the platform.

The utility model provides a pair of large-scale hydroelectric set vertical derivation cooler overhauls platform, should overhaul the platform and filled the blank that the derivation cooler tank lid overhauld to this kind of mounting means and mounted position, and utilize this to overhaul the platform and can reduce the risk in the work progress, improve the efficiency and the quality that the lower part tank lid of derivation cooler overhauld, can reduce operation personnel's construction risk simultaneously. Because the derivation cooler of this kind of mounting means and installation position is used widely in large-scale hydropower station at present, so this maintenance platform has extensive application and spreading value, can bring abundant economic benefits.

Drawings

The invention will be further explained with reference to the following figures and examples:

fig. 1 is a schematic view of the overall structure of the present invention;

FIG. 2 is a left side view of FIG. 1;

FIG. 3 is a top view of FIG. 1;

in the figure: platform 1, guardrail 2, entry 3, peg 4, locking link plate 5, locking bolt 6, staircase 7, couple 8, puller plate 9, jackscrew 10, supporting leg 11.

Detailed Description

As shown in fig. 1, the maintenance platform for the vertical derivation cooler of the large hydroelectric generating set comprises a platform 1, wherein the height between the maintenance platform and the upper surface of a control ring is 350-400 mm; the platform is about 1500mm long along the radial direction of the control ring, the outer side of the platform protrudes out of the control ring and extends for about 200mm, and the width of the platform along the circumferential direction of the control ring is 800 mm-1000 mm; the platform 1 is provided with a guardrail 2, the guardrail 2 is arranged around the upper side of the platform 1, the height of the guardrail 2 is 1200mm, the lower end of the guardrail 2 can be provided with a skirting board, the height of the skirting board is 180mm, one side of the guardrail 2 is provided with an inlet 3, a constructor can conveniently enter the platform 1, the inlet 3 is provided with a hanging shaft 4, one side of the platform 1, which is far away from the hanging shaft 4, is provided with a locking hanging plate 5, the locking hanging plate 5 is in a [ "shape, the bottom of the locking hanging plate 5 is provided with a locking bolt 6 which is tightly propped against the bottom of a control ring, the length of the locking bolt 6 is about 600mm, M24 is a carbon steel full-thread screw; still include staircase 7, staircase 7 is about 2000mm long, and the upper end of staircase 7 is equipped with couple 8, and couple 8 is hung and is established on peg 4.

During the specific use, place platform 1 on the control ring upside, screw up locking bolt 6 and fix locking link plate 5 on the control ring, realize the fixed of platform 1, hang the couple 8 of 7 upper ends of staircase and establish on peg 4, can make the maintainer climb to 3 positions of entry from staircase 7 and get into 1 tops of platform and overhaul.

This overhaul platform dismouting realizes easily, is connected through the hanging of staircase 7 with peg 4 dress formula, makes things convenient for 7 dismouting of staircase and removal.

Preferably, a tightening plate 9 is arranged on the platform 1 near the hanging shaft 4, and a jackscrew 10 tightly pressed on the inner side of the control ring is arranged on the tightening plate 9.
