Description

Technical Field

[0001] The utility model relates to an adjustable pipeline fixing support device for replacing a trough bottom bendable joint, belonging to the technical field of electrolytic aluminum production equipment. Background Art

[0002] The compressed air pipe network at the bottom of the electrolytic aluminum cell is equipped with a flexible rubber joint that plays an insulating role. It is time-consuming and laborious to replace the flexible rubber joint each time. The previous replacement process is: close the valve of the steam-water separator or the gas tank, release the pressure, and disassemble the joints. Since the pipeline is long, it will cause the pipeline to be uneven after disassembly, which brings inconvenience to the replacement work. The previous replacement method is for people to hold up the pipeline, and the staff will install the joint and tighten it. In this way, due to the uneven pipeline, there may be air leakage at the joint after the air supply is restored. At this time, it is necessary to loosen the bolts and adjust it again. Not only is it troublesome, but it may also cause the tank to be unstable. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide an adjustable pipeline fixing support device for replacing the bendable joint at the bottom of the tank, so as to solve the above problems.

[0004] The utility model discloses an adjustable pipeline fixing support device for replacing a groove bottom bendable joint, comprising a base, a vertical lower support rod being provided on the base, a screw rod being provided on the top of the lower support rod, the screw rod being fixedly connected to the lower support rod, and an adjusting nut being provided on the screw rod through threaded cooperation; and also comprising an arc-shaped pipeline support plate, a vertical upper support rod being connected to the lower part of the pipeline support plate, the upper support rod being sleeved on the screw rod and supported by the adjusting nut.

[0005] Before shutting down the gas and disassembling, the replaced joint can be adjusted and supported. By turning the adjusting nut to adjust the height of the pipeline support plate, the problem of uneven pipelines can be greatly avoided, the replacement time can be reduced, and the probability of failure can be greatly reduced.

[0006] Preferably, the lower support rod and the upper support rod are both square tubes, and their cross-sectional shapes and sizes are the same.

[0007] Preferably, a limit plate is fixed on each side of the upper support rod to prevent the pipeline support plate from rotating when the adjusting nut is turned.

[0008] The center of the upper support rod of the utility model is provided with an inner sleeve, and the inner diameter of the inner sleeve is matched with the outer diameter of the screw rod.

[0009] Wherein, the inner sleeve is fixedly connected to the inner wall of the upper support rod through a connecting plate, and the connecting plate is located between the inner wall of the upper support rod and the outer wall of the inner sleeve.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model discloses an adjustable pipeline fixing support device for replacing a groove bottom bendable joint.

[0012] 1. Improve work efficiency: Since the device can support and adjust the pipe at the flexible rubber joint to be replaced in advance, so that the pipe remains flat, there is no need to manually support the pipe during the replacement process, which greatly simplifies the operation steps, reduces the difficulty of work, and thus significantly improves work efficiency.

[0013] 2. Reduce the probability of failure: Since the device can pre-adjust the height of the pipeline support plate before replacement to keep the pipeline level, it can avoid failures such as air leakage at the joints caused by uneven pipelines, thereby greatly reducing the probability of failure.
