Description

Technical Field

[0001] The invention relates to the technical field of flange installation, and in particular to a bevel flange installation tool. Background Art

[0002] Flange, also known as flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. There are also flanges used on the inlet and outlet of equipment to connect two equipment, such as reducer flanges. Flange connection or flange joint refers to a detachable connection that is connected by flanges, gaskets and bolts as a combined sealing structure. Pipe flange refers to the flange used for piping in pipeline devices. When used on equipment, it refers to the inlet and outlet flanges of the equipment. There are holes on the flange, and bolts connect the two flanges tightly. Gaskets are used to seal between flanges.

[0003] At present, flanges are widely used in the connection of steel structure tower pipe columns. Good flange assembly precision control will greatly reduce the on-site work such as correction and hole expansion in the later tower assembly process, which is conducive to shortening the construction period and saving costs. Many tower steel structures will be waisted between each room, mainly by setting a certain tilt angle at the bottom flange of the pipe column to achieve the waisting. This tilt angle is generally very small, which is reflected in the difference of only millimeters in the distance between the flanges at both ends of the tower column.

[0004] However, in actual processing, the inclination angle is usually controlled by measuring the upper and lower size difference of the inclined flange, which is difficult to control and requires repeated measurements, requiring the flange assemblers to be particularly careful. Summary of the invention

[0005] 1. Technical issues to be solved

[0006] The purpose of the present invention is to solve the problem in the prior art that the assembly accuracy of the bevel flange is difficult to control and needs repeated measurements, and to propose a bevel flange installation tool.

[0010] The middle part of the second fixed plate is fixedly connected to a universal joint by a fastening bolt, a tilt adjustment shaft is rotatably inserted in the universal joint, an adjusting bolt is threadedly inserted at one end of the universal joint, a threaded hole corresponding to the adjusting bolt is provided on the tilt adjustment shaft, a center pin shaft is slidably inserted at one end of the tilt adjustment shaft close to the universal joint, and the longitudinal adjustment shaft and the tilt adjustment shaft are fixedly connected by an extension shaft.

[0011] Preferably, both ends of the extension shaft are provided with mounting grooves corresponding to the longitudinal adjustment shaft and the inclination adjustment shaft respectively.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Embodiment 1:

[0023] Reference Figure 1, a bevel flange installation tool, comprising a symmetrically arranged first fixing plate 1 and a second fixing plate 2, wherein the first fixing plate 1 and the second fixing plate 2 are both provided with a plurality of fastening openings 12 on opposite sides thereof, for conveniently fixing the flanges, a longitudinal adjustment shaft 3 is slidably inserted in the first fixing plate 1 for adjusting the distance between the flanges at both ends, and guide grooves are provided on the first fixing plate 1 and the longitudinal adjustment shaft 3 for conveniently adjusting the distance between the flanges at both ends;

[0024] In the present invention, the outer thread of the longitudinal adjustment shaft 3 is sleeved with a locking ring 4 and an adjusting ring 5 for adjusting and fixing the flange. The locking ring 4 and the adjusting ring 5 are respectively arranged on both sides of the first fixing plate 1. The locking ring 4 and the adjusting ring 5 are both rotatably inserted in the middle of the first fixing plate 1, and the longitudinal installation size of the flange can be accurately adjusted. The flange adjusted in place can be fixed by the locking ring 4;

[0025] In the present invention, the middle part of the second fixing plate 2 is fixedly connected with a universal joint 7 by a fastening bolt 6, a tilt adjustment shaft 8 is rotatably inserted in the universal joint 7, the longitudinal adjustment shaft 3 and the tilt adjustment shaft 8 are both hollow, an adjustment bolt 9 is threadedly inserted at one end of the universal joint 7, and a threaded hole corresponding to the adjustment bolt 9 is provided on the tilt adjustment shaft 8;

[0026] In the present invention, a center pin shaft 10 is slidably inserted into one end of the inclination adjustment shaft 8 close to the universal joint 7, and the longitudinal adjustment shaft 3 and the inclination adjustment shaft 8 are fixedly connected by an extension shaft 11, so that the tool processing range can be expanded to adapt to pipes of different lengths. Both ends of the extension shaft 11 are respectively provided with installation grooves corresponding to the longitudinal adjustment shaft 3 and the inclination adjustment shaft 8.

[0027] In the present invention, when the flange is installed, the longitudinal adjustment shaft 3, the extension shaft 11, and the inclination adjustment shaft 8 are inserted into the pipe column and pressed. Figure 1 Assemble the bevel flange installation tool and the flanges at both ends; when the flanges at both ends have been embedded in the pipe column, rotate the locking ring 4 to lock the left flange; use a small wrench to rotate the adjusting bolt 9 to adjust the inclination of the second fixing plate 2, and spot weld the bevel flange after the difference in distance between the upper and lower points of the bevel flange and the left flange meets the requirements of the drawing; loosen the locking ring 4, rotate the adjusting ring 5 to move the first fixing plate 2 along the slide groove of the longitudinal adjustment shaft 3, until the distance between the flanges at both ends meets the requirements of the drawing, and then spot weld the left flange; remove the connecting bolts between the flanges on both sides and the first fixing plate 1 and the second flange fixing plate 2, remove the connecting bolts between the universal joint 7 and the second fixing plate 2, take out the tool, and the pipe column flange assembly welding is completed. The next time you assemble the same type of pipe column, directly bolt the flange to the first fixing plate 1 and the second fixing plate 2, and bolt the universal joint 7 to the second fixing plate 2, without the need to adjust again.
