Problems solved by technology

[0002] Due to the different types of steam seals, the spacing between the teeth of the steam seals is different, and the teeth are closely arranged, so it is necessary to make different scraping tools according to different types of steam seals for each maintenance, which is time-consuming and labor-intensive; if manual maintenance is used, not only A waste of human resources may cause personal injury, and at the same time, it will cause damage to the steam seal to a certain extent, which cannot meet the maintenance requirements. In view of the above problems, the existing patent announcement number is CN208662721U Patent announced a steam seal repair scraping The device is equipped with a scraping strip assembly. The scraping strip assembly is detachably installed on the stud and locked by two lock nuts, so that the user can change the scraping strip with different thicknesses to adapt to different types of steam. The distance between the seal teeth of the seal can realize the repair and scraping of different types of seals
[0003] However, the above-mentioned device needs to rely on manual scraping, which is extremely laborious and inefficient, and it is difficult to scrape the seal teeth. To solve this problem, an optimized scraping device and scraping method

Embodiment 1

[0034] see Figure 1-4 , in an embodiment of the present invention, a steam seal repairing and scraping device includes a base 1 and a top plate 3 arranged above it, both sides of the lower end of the top plate 3 are connected and fixed to the base 1 through support columns 2, and There is a fixture 13 for fixing the steam seal gear A to be processed. There is a hanging plate 5 under the top plate 3. The upper end of the hanging plate 5 is connected to the displacement assembly 4 for driving it to move left and right. The displacement assembly 4 can drive the scraping repair. The parts move along the seal teeth A;

[0035] The bottom of the hanging plate 5 is provided with a mounting plate 8, and the left and right ends of the mounting plate 8 are symmetrically provided with guide sleeves 9, and the guide sleeve 9 is slid to be provided with a guide post 6, and the upper end of the guide post 6 is connected to the hanging plate. The lower end of 5 is connected and fixed, and ...

Embodiment 2

[0042] Figure 5 As shown, in order to facilitate the timely discharge of the material scraped by the scraper member 10 and avoid the difficulty of the material being squeezed to the scraper pulley, the fixed shaft is arranged at an inclination, and the first scraper 101 and the second scraper 102 meet the material The edge and the horizontal plane are set at an acute angle, so that the scraping surface stroke of the scraping member 10 will lead the material in the tooth groove to the guide surface, and the material in the tooth groove can be continuously pushed out during the movement of the scraper plate 10, reducing the Reduce the scraping resistance and improve the scraping effect.

Embodiment 3

[0044] In order to facilitate the adjustment of the height of the top plate 3, the support column 2 can be replaced by a hydraulic lifting column, so that the overall scraping height of the device can be fine-tuned.

Abstract

The invention discloses a steam seal repairing and scraping device and method. The device comprises a base and a top plate arranged above the base; the two sides of the lower end of the top plate arefixedly connected to the base through supporting columns; clamps used for fixing a steam seal tooth A to be machined is arranged on the base; a lifting plate is arranged below the top plate; the upperend of the lifting plate is connected to a displacement assembly for driving the lifting plate to move left and right; and a mounting plate is arranged below the lifting plate. According to the steamseal repairing and scraping device and method, an improvement is made for overcoming the defects of an existing device, and a mechanical scraping device is arranged, so that the labor intensity is reduced, and the material scraping efficiency is improved; and the scraping intensity is optimized, under the action of the displacement assembly, a scraping part can slide along a tooth groove of the steam seal tooth A, due to the fact that the mounting plate can slide up and down along the lifting plate, under the deformation of reset springs, the mounting plate can be subjected to automatic height adjustment along with the radian of the tooth groove surface of the steam seal tooth A, the problem of overlarge damage to the groove surface of the steam seal tooth A can be solved, and therefore the defect that in the prior art, force application is uneven due to manual material scraping can be overcome.
