Detailed Description
The invention is further described below with reference to the figures and examples.
As shown in fig. 1, fig. 2 and fig. 3, a special tool for repairing a flange coating comprises a positive threaded rod 1, a negative threaded rod 2, an adjusting nut 3, a fixing plate 4, a body 5 and a base 6. The upper and lower halves of the body 6 are connected by the fixing plate 4. The positive screw rod 1, the negative screw rod 2, the adjusting nut 3 and the base 6 are positioned inside the body 5. The base 6 is welded to the inner wall of the body 5. The base 6 is respectively in threaded connection with the outer side ends of the positive screw rod 1 and the negative screw rod 2. The adjusting nut 3 is respectively in threaded connection with the inner side ends of the positive screw rod 1 and the negative screw rod 2.
The whole positive screw rod 1 is a cylindrical screw rod, the upper end of the positive screw rod is in threaded connection with the base 6, and the lower end of the positive screw rod is in threaded connection with the adjusting nut 3. The whole reverse screw rod 2 is a cylindrical screw rod, the screw thread on the outer surface is left-handed and up, the upper end is in threaded connection with the adjusting nut 3, and the lower end is in threaded connection with the base 6. Because the thread directions of the positive screw rod 1 and the negative screw rod 2 are completely opposite, when the adjusting nut 3 is rotated along the positive direction and the negative direction, the outward or inward synchronous adjustment of the positive screw rod 1 and the negative screw rod 2 can be realized.
As shown in fig. 4, the adjusting nut 3 is an elongated nut as a whole. When the adjusting nut 3 is rotated, the positive screw rod 1 and the negative screw rod 2 are driven to synchronously adjust outwards or inwards, so that the outer diameter of the body 5 is changed.
As shown in fig. 5, the fixing plate 4 is a circular arc plate, a rectangular hollow strip is disposed at the center along the length direction, and the screw penetrates through the hollow strip and is then fixedly connected with the body 5. The fixed plate 4 has two, sets up respectively on two left and right connecting portion of body 5 upper and lower two halves part, when 5 external diameters of body change, through the position of adjusting screw in the fretwork is rectangular, satisfies the needs of regulation stroke.
The body 5 is integrally formed by an upper semicircular arc and a lower semicircular arc which have the same structure and are arranged oppositely and used for supporting the pipe wall.
The base 6 is integrally provided with two nuts, is respectively arranged at the central positions of the upper and lower semicircular arc inner walls of the body 5 and is welded with the body 5. The lower end of the upper base 6 is connected with the upper end of the main screw rod 1 in a threaded manner and tightly fastened by a nut. The upper end of the lower base 6 is connected with the lower end of the reverse-thread screw 2 in a threaded manner and tightly fastened by a nut.
In the present embodiment, the positive screw rod 1, the negative screw rod 2, the adjusting nut 3, the fixing plate 4, the body 5 and the base 6 are made of stainless steel materials.
The working principle of the invention is as follows:
the tool of the invention is placed into the pipe with the tool in place visually at the orifice. The adjusting nut 3 is rotated, the body 5 is pushed to the inner wall of the pipe orifice through the outward movement of the positive screw rod 1 and the negative screw rod 2, the supporting effect is achieved, the leveling of the coating reference surface is not damaged by the upper edge surface of the body 5 and the original flange surface, and the tool is calibrated by the upper end surface of the body 5. The adjusting nut 3 is turned again so that the body 5 butts against the pipe wall. The fixing plate 4 is used for fixedly connecting the upper and lower semi-circular arcs of the body 5. After the fixation is finished, constructors can construct, fill the corrosion pits with the coating, brush and scrape the coating, and therefore the flatness of the coating can be guaranteed, and the sealing performance of the flange face is guaranteed.
The method of carrying out the present invention has been described in detail with reference to the examples, but the present invention is not limited to the examples described above, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. The prior art can be used for the content which is not described in detail in the present specification.
