For those skilled in the art, the specific meaning of the above-mentioned terms in the embodiments of the present application can be understood according to the specific circumstances.

[0023] In combination Figs. 1-2 As shown in the drawings, a flange sealing ring replacement device, comprising: a support plate 1 and a lifting assembly 2; the support plate 1 is provided with a threaded hole 11 penetrating the upper and lower surfaces; the lifting assembly 2 comprises: a drive screw 21, a fixed plate 22 and a fixed chain 23, the drive screw 21 is screwed into the threaded hole 11 of the support plate 1, the fixed plate 22 is arranged below the support plate 1, the bottom end of the drive screw 21 is rotatably connected with the fixed plate 22, the two ends of the fixed chain 23 are respectively connected with the two sides of the fixed plate 22, and at least one end is detachably connected, and the fixed chain 23 and the fixed plate 22 define a clamping position for clamping a pipeline.

[0024] Exemplarily, the length of the fixing chain 23 can be adjusted according to the required outer circumference of the pipe to be clamped. When the flange sealing ring needs to be replaced, one end of the fixing chain 23 is first detached from one side of the fixing plate 22, the device of the application is then erected on the pipe on one side of the flange, and the clamping position is arranged on the pipe near the flange. The fixing plate 22 is arranged on the top of the pipe, and then the pipe is clamped by the fixing chain 23. One end of the fixing chain 23 is then installed back to one side of the fixing plate 22. At this time, the lifting assembly 2 fixes the pipe, and the support plate 1 is parallel to the pipe. The operator fixes the support plate 1 with one hand so that it does not displace, and rotates the drive screw 21 with the other hand so that the fixing plate 22 and the fixing chain 23 drive the pipe to move up and down relative to the support plate 1. At this time, the pipe at the flange connection is offset up and down from another pipe that is not clamped by the lifting assembly 2, so that an offset gap is generated between the two flanges. Then the position of the drive screw 21 is fixed, and the operator can take out the sealing ring from the gap between the two flanges. Then the new sealing ring is put into the gap, and finally the drive screw 21 is rotated to restore the pipe to its original position. The detachable connection between the support plate 1 and the drive screw 21, and the detachable connection between the fixing plate 22 and the fixing chain 23 make the device of the application suitable for replacing the flange sealing ring in a small space inside a mechanical equipment, and the operation is simple and easy to operate, which is beneficial to improve the efficiency of replacing the flange sealing ring.

[0025] In some embodiments, at least two threaded holes 11 are arranged on the support plate 1, and at least two lifting assemblies 2 are arranged on the support plate 1. Each lifting assembly 2 is connected to a threaded hole 11. The clamping positions of the multiple lifting assemblies 2 are used to connect to two pipes.

[0026] Exemplarily, two threaded holes 11 are arranged on the support plate 1, and two lifting assemblies 2 are arranged on the support plate 1. The two lifting assemblies 2 are fixedly connected to two pipes on both sides of the flange. One of the two lifting assemblies 2 is fixedly connected to the support plate 1 and does not displace. The drive screw 21 of the other lifting assembly 2 is rotated so that one of the pipes is fixed and the other pipe is driven by the fixing plate 22 and the fixing chain 23 to move up and down relative to the support plate 1. This is beneficial to faster generate an offset between the two flanges and improve the efficiency of replacing the flange sealing ring.

[0027] In some embodiments, the number of threaded holes 11 is multiple. Exemplarily, multiple threaded holes 11 are arranged at equal intervals on the support plate 1, which is beneficial to better and stably install multiple lifting assemblies 2 on the support plate 1.

[0028] In some embodiments, the lifting assembly 2 further comprises a nut member 24, the nut member 24 is screwed with the drive screw 21, and the nut member 24 is located above the support plate 1, used to lock the drive screw 21 to the support plate 1. Exemplarily, the outer of the nut member 24 is provided with anti-skid protrusions, which facilitates the operator to better rotate the nut member 24. A plurality of lifting assemblies 2 are respectively fixed on two pipelines on both sides of the flange, wherein the lifting assembly 2 on the pipeline which needs to be relatively displaced with the support plate 1 is disassembled from the nut member 24, the lifting assembly 2 on the pipeline which needs to be fixed is fixedly connected with the nut member 24, the nut member 24 is screwed with the drive screw 21, and the bottom of the nut member 24 is fixedly connected to the top of the support plate 1, which is beneficial to ensure that the two pipelines are relatively displaced and the two flanges are offset to replace the flange sealing ring. When the two pipelines have been offset and the sealing ring can be replaced, the operator can also fix the position of the drive screw 21 which has been displaced through the nut member 24, to prevent the drive screw 21 from loosening during the replacement of the sealing ring.

[0029] In some embodiments, the lifting assembly 2 further comprises a bearing seat 25, the bearing seat 25 is installed at the top end of the fixed plate 22, and the drive screw 21 is rotatably connected with the fixed plate 22 through the bearing seat 25. This facilitates the modular assembly of the device and is beneficial to the device to enter the equipment or mechanical parts with small space to replace the flange sealing ring.

[0030] In some embodiments, the support plate 1 comprises a top plate 12 and a limiting plate 13, the threaded hole 11 is formed on the top plate 12, and the limiting plate 13 is protrudingly arranged downward along opposite sides of the top plate 12. This is beneficial to limit the movement of the drive screw 21 and prevent the drive screw 21 from damaging the bearing seat 25 below during the upward and downward movement.

[0031] In some embodiments, the top of the fixed plate 22 is provided with two mounting seats 26 on both sides, the two mounting seats 26 are located on both sides of the drive screw 21, and the two ends of the fixed chain 23 are connected with the fixed plate 22 through one of the mounting seats 26. This is beneficial to better arrange the length and position of the fixed chain 23, and is beneficial to the fixed chain 23 and the fixed plate 22 to jointly tightly fix the pipeline.

[0032] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
