Abstract
The utility model discloses an adjustable supporting structure of pumped storage generator motor induced draft plate comprises upper end support, upper end support waist type hole, location split pin, fixed plate, adjusting bolt, lower extreme support screw, lower extreme support, induced draft plate. After the left-handed screw thread of adjusting bolt upper segment is twisted into the fixed plate, the right-handed screw thread of its hypomere is being connected with the dextrorotation screw hole on the lower extreme support, then the right-handed screw thread rotates adjusting bolt and realizes the quick adjustment to the mounting height of lower extreme support and induced draft plate, finishes adjusting and passes the punching hole of adjusting bolt end with the locating cotter pin to pass the punching hole of upper end support, then opens the opening and prevents that adjusting bolt is not hard up. The utility model discloses can simple quick adjustment induced air board mounting height to can drop to the minimum improvement security with the fastener quantity of rotor top.
Description
Technical Field
The utility model relates to a hydraulic generator technical field especially relates to an adjustable supporting structure of pumped storage generator motor induced air board.
Background
The most fixed induced draft plate supporting structure that adopts of pumped storage generating motor, the installation of induced draft plate whether reach the installation and require direct influence the effect of keeping out the wind and influence the whole cooling effect of generator even, induced draft plate all adopts fixed supporting structure in the past, need adjust the mode that the support height can only adopt gasket or processing base like the building site, not only work load is big but also hardly guarantee induced draft plate axial altitude unanimity. The ventilation effect of the unit cannot be effectively guaranteed.
Disclosure of Invention
The utility model aims at disclosing an adjustable supporting structure of pumped storage generator motor induced draft plate comprises upper end support, upper end support waist type hole, positioning split pin, fixed plate, adjusting bolt, lower extreme support screw, lower extreme support, induced draft plate, and is a whole with upper end support and fixed plate welding, and lower extreme support welds to be a whole with induced draft plate, makes lower extreme support and induced draft plate can reciprocate through rotatory adjusting bolt.
The upper section of the threaded part of the adjusting bolt is provided with left-handed threads, the lower section of the threaded part of the adjusting bolt is provided with right-handed threads, the diameter of the left-handed threads is larger than that of the right-handed threads, and three groups of through holes perpendicular to the plane are arranged at the hexagonal position of the end of the adjusting bolt.
The upper end support is provided with an axial waist-shaped hole of the upper end support at the upper position of the fixing plate, the length of the waist-shaped hole is equivalent to the length of the left-hand thread of the adjusting bolt, the fixing plate is provided with a screw hole with the same diameter as the left-hand thread of the adjusting bolt, and the end of the lower end support is provided with a screw hole of the lower end support with the same diameter as the right-hand thread of the adjusting bolt.

Detailed Description
As shown in fig. 1, the adjustable support structure of the induced draft plate of the pumped storage generator motor comprises an upper end support 1, an upper end support waist-shaped hole 2, a positioning split pin 3, a fixing plate 4, an adjusting bolt 5, a lower end support screw hole 6, a lower end support 7 and an induced draft plate 8, wherein the upper end support 1 and the fixing plate 4 are welded into a whole, the lower end support 7 and the induced draft plate 8 are welded into a whole, and the lower end support 7 and the induced draft plate 8 can move up and down by rotating the adjusting bolt 5.
The upper section of the threaded part of the adjusting bolt 5 is provided with left-handed threads 10, the lower section of the threaded part is provided with right-handed threads 11, the diameter of the left-handed threads 10 is larger than that of the right-handed threads 11, and three groups of through holes 9 perpendicular to the plane are arranged at the hexagonal position of the end of the adjusting bolt 5.
The upper end bracket 1 is provided with an axial upper end bracket waist-shaped hole 2 at the position above the fixed plate 4, the length of the upper end bracket waist-shaped hole is equivalent to the length of a left-hand thread 10 of the adjusting bolt 5, the fixed plate 4 is provided with a screw hole 12 with the same diameter as the left-hand thread 10 of the adjusting bolt 5, and the end of the lower end bracket 7 is provided with a lower end bracket screw hole 6 with the same diameter as a right-hand thread 11 of the adjusting bolt 5.
During the use, the left-handed threads 10 of the adjusting bolt 5 are all screwed into the fixing plate 4, the right-handed threads 11 of the adjusting bolt are aligned with the lower end support screw hole 6 on the lower end support 7, then the adjusting bolt 5 is rotated rightwards, the lower end support 7 and the induced draft plate 8 are quickly lifted to the required height, finally the positioning split pin 3 penetrates through the through hole 9 on the adjusting bolt 5 and the upper end support waist-shaped hole 2, and the opening is opened outside the upper end support waist-shaped hole 2 to prevent the adjusting bolt 5 from rotating.
It should be noted that the scope of the present invention is not limited to the above-mentioned embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. It is intended that the present invention also includes such modifications and variations as come within the scope of the appended claims and their equivalents.
