Description

Technical Field

[0001] This utility model relates to the field of pipeline fixing support technology, specifically a fixing support for cryogenic oxygen pipelines. Background Technology

[0002] In modern industrial production, cryogenic oxygen pipelines are widely used in many fields such as chemical, metallurgical, and medical industries. Their safe and stable operation is crucial for the normal operation of production processes and the safety of personnel and equipment. As a key component for supporting and fixing cryogenic oxygen pipelines, pipeline fixing supports directly affect the reliability of the pipeline system.

[0003] Traditional cryogenic oxygen pipeline fixing supports have some shortcomings in practical applications. In terms of installation, due to the large weight of the cryogenic oxygen pipeline itself, when it is necessary to adjust the position of the pipeline connection flange hole to achieve precise connection, it often relies on manually rotating the pipeline. This operation method not only consumes a lot of manpower but is also inefficient. At the same time, there is a risk that the installation position may be deviated due to the effort required for rotation, which in turn affects the sealing of the pipeline connection and creates a safety hazard for oxygen leakage.

[0008] A fixing bracket for cryogenic oxygen pipelines includes: a support device, with a fixing device fixedly connected to the outer wall of the support device; the support device includes a mounting base plate, with a support plate fixedly connected to the outer wall of the top of the mounting base plate, a knob rotatably connected to the inner wall of the support plate, a threaded rod threadedly connected to the inner wall of the knob, an anti-detachment plate fixedly connected to the outer wall of the bottom of the threaded rod, a support arc plate fixedly connected to the outer wall of the top of the threaded rod, and a ball bearing rotatably connected to the inner wall of the support arc plate, with an anti-slip groove formed on the outer wall of the ball bearing.

[0009] Preferably, the outer wall of the anti-detachment plate is slidably connected to the inner wall of the support plate, the balls are arranged in a ring around the central point of the support arc plate, and the anti-slip grooves are arranged in a ring around the central point of the balls, so that the oxygen tube can rotate freely by means of the rotational characteristics of the balls when it comes into contact with them.

[0010] Preferably, the fixing device includes a lower clamp, the inner wall of which has an arc-shaped groove, and a lower anti-slip pad is symmetrically fixedly connected to the inner wall of the lower clamp.

[0013] (III) Beneficial Effects

[0014] This invention provides a fixing bracket for cryogenic oxygen pipelines. It has the following beneficial effects:

[0015] (i) The support device has a ring array of balls connected to the inner wall of the support arc plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a fixed bracket for a low-temperature oxygen pipeline, comprising: a support device 1, a fixing device 2 fixedly connected to the outer wall of the support device 1; the support device 1 includes a mounting base plate 11, a support plate 12 fixedly connected to the outer wall of the top of the mounting base plate 11, a knob 13 rotatably connected to the inner wall of the support plate 12, a threaded rod 14 threadedly connected to the inner wall of the knob 13, an anti-detachment plate 15 fixedly connected to the outer wall of the bottom of the threaded rod 14, a support arc plate 16 fixedly connected to the outer wall of the top of the threaded rod 14, a ball bearing 17 rotatably connected to the inner wall of the support arc plate 16, and an anti-slip groove 18 formed on the outer wall of the ball bearing 17.

[0024] The outer wall of the anti-detachment plate 15 is slidably connected to the inner wall of the support plate 12. The balls 17 are arranged in a ring along the central point of the support arc plate 16. The anti-slip grooves 18 are arranged in a ring along the central point of the balls 17, so that the oxygen tube can rotate freely when it comes into contact with the balls 17, thanks to the rotational characteristics of the balls 17.

[0025] The fixing device 2 includes a lower clamp 21, the inner wall of which has an arc-shaped groove 22, and a lower anti-slip pad 23 is symmetrically fixedly connected to the inner wall of the lower clamp 21. The outer wall of the top of the lower clamp 21 has symmetrically opened mounting holes 24, and a bolt 25 is slidably connected to the inner wall of the mounting hole 24. An upper clamp 26 is rotatably connected to the outer wall of the top of the bolt 25, and an upper anti-slip pad 27 is fixedly connected to the inner wall of the upper clamp 26.

[0026] The lower anti-slip pads 23 are set on both sides of the arc groove 22. The outer wall of the top of the lower clamp 21 contacts the outer wall of the bottom of the upper clamp 26, which facilitates the all-round wrapping and fixing of the oxygen tube, prevents the oxygen tube from sliding, and can also play a buffering and protective role to a certain extent.

[0027] The outer wall of the top of the support plate 12 is fixedly connected to the outer wall of the bottom of the lower clamp 21. The outer wall of the support arc plate 16 is slidably connected to the inner wall of the arc groove 22. The outer wall of the threaded rod 14 is slidably connected to the inner wall of the bottom of the lower clamp 21. When the knob 13 is rotated along the support plate 12, the threaded connection between the knob 13 and the threaded rod 14 can drive the threaded rod 14 to move up and down.

[0028] When in use, place the oxygen tube on the fixing device 2. The oxygen tube can rotate circumferentially through the support arc plate 16 on the support device 1, which facilitates the installation and docking of the connecting flange hole and avoids the oxygen tube being too heavy and difficult to rotate.

[0029] First, place the oxygen tube on the lower clamp 21. At this time, the oxygen tube contacts the ball bearing 17 rotatably connected to the inner wall of the support arc plate 16. Since the ball bearing 17 is distributed in a circular array along the axis of the support arc plate 16, and the anti-slip groove 18 on its outer wall is arranged in a circular array along its own axis, the oxygen tube can rotate freely when it contacts the ball bearing 17, thanks to the rotational characteristics of the ball bearing 17. This also avoids wear on the outer wall of the oxygen tube, greatly facilitating the user to adjust the position of the connecting flange hole on the oxygen tube so that it can be accurately aligned with the docking parts.

[0030] After the position of the oxygen pipe connection flange hole is adjusted, rotate the knob 13 along the support plate 12. Utilize the threaded connection between the knob 13 and the threaded rod 14 to drive the threaded rod 14 to move downward. The threaded rod 14 drives the support arc plate 16 to slide downward and gradually retract into the arc groove 22. During this process, the height of the oxygen pipe decreases until it contacts the lower anti-slip pad 23, which is symmetrically fixed to the inner wall of the lower clamp 21, providing initial fixation and anti-slip effect for the oxygen pipe.

[0031] Next, the upper clamp 26 is connected to the lower clamp 21 by bolts 25. Bolts 25 pass through the mounting hole 24 at the top of the lower clamp 21 and are rotatably connected to the upper clamp 26. By tightening the nut on the bolt 25, the upper clamp 26 gradually moves closer to the lower clamp 21 until the upper anti-slip pad 27, which is fixedly connected to the inner wall of the upper clamp 26, is tightly attached to the upper surface of the oxygen pipe. At the same time, it works together with the lower anti-slip pad 23 to form a comprehensive wrapping and fixation of the oxygen pipe, preventing the oxygen pipe from sliding. It can also play a certain role in buffering and protection, avoiding damage to the low-temperature oxygen pipeline caused by hard compression. This achieves a stable fixation of the low-temperature oxygen pipeline, thus successfully completing the installation and docking operation.
