Description

Technical Field

[0001] This utility model belongs to the field of fixed support technology, and in particular relates to a fixed support for a cryogenic process gas detection device. Background Technology

[0002] Cryogenic process gas detection devices are specialized equipment used in cryogenic environments to detect process gas leaks, purity, and concentration in real time. The core components consist of a cryogenically adapted sensor, a data transmission module, and a protective housing. They are widely used in liquefied natural gas, air separation, and cryogenic chemical industries. Their function is to provide timely warnings of gas leak risks, ensuring process stability and personnel safety. Because gas leaks in cryogenic environments can easily cause frostbite, explosions, or equipment damage, this device is required for 24 / 7 monitoring. The use of specialized mounting brackets is due to the unique conditions in cryogenic environments: firstly, the surface temperature of cryogenic pipelines and equipment is extremely low, and direct installation would lead to low-temperature failure of device components; the brackets, through their thermal insulation structure, block the conduction of low temperatures.

[0003] However, the continuous vibration generated during the use of existing fixed brackets will gradually cause the threaded connection to loosen. In addition, metal materials are prone to shrinkage and deformation in low-temperature environments, which will further aggravate the increase in thread clearance. Ultimately, this may cause the mounting rod to loosen and the detector to fall off, posing risks to equipment damage and process safety. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed bracket for a cryogenic process gas detection device. By setting up an installation part, the existing fixed brackets are solved by addressing the problem that continuous vibration during use will gradually cause the threaded connection to loosen, and the metal material is prone to shrinkage and deformation in low temperature environments, which will further aggravate the increase in thread clearance. Ultimately, this may lead to the installation rod loosening and the detector falling off, resulting in equipment damage and process safety risks.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a fixed bracket for a cryogenic process gas detection device, comprising a U-shaped fixing rod and a detector disposed above the U-shaped fixing rod, and further comprising: a mounting part mounted on the U-shaped fixing rod; two fixing parts, both of which are disposed on the U-shaped fixing rod; the mounting part including a connecting assembly mounted on the U-shaped fixing rod; and a limiting assembly disposed on the U-shaped fixing rod; the connecting assembly including a fixing plate disposed on the U-shaped fixing rod, a connecting hollow rod fixedly connected to the front side of the fixing plate, a fixing block fixedly connected to the front side of the connecting hollow rod, a threaded hollow rod slidably connected to the inner wall of the fixing block, and an installation rod threadedly connected to the inner wall of the threaded hollow rod; wherein, the inner wall of the threaded hollow rod is provided with threads, and the detector is fixedly connected to the installation rod.

[0007] Furthermore, the fixing part includes a sleeve assembly mounted on the U-shaped fixing rod; and a compression assembly disposed on the U-shaped fixing rod; wherein both the sleeve assembly and the compression assembly are located on the U-shaped fixing rod.

[0008] Furthermore, the limiting component includes a spring 1 disposed within a fixed block, the bottom of the spring 1 being fixedly connected to the fixed block, the top of the spring 1 being fixedly connected to a threaded hollow rod, a sliding rod disposed within the connecting hollow rod, a fixed plate 2 being fixedly connected to the rear side of the sliding rod, and an elastic element disposed on the sliding rod; wherein, the sliding rod extends into the mounting rod, and the elastic element includes a spring 2 sleeved on the outer wall of the sliding rod, the rear side of the spring 2 being fixedly connected to the fixed plate 2, and the front side of the spring 2 being fixedly connected to the connecting hollow rod; wherein, the initial state of the spring 2 is a natural state.

[0009] Furthermore, the sleeve assembly includes a first fixing ring slidably connected to the outer wall of the U-shaped fixing rod, and a second fixing ring slidably connected to the outer wall of the U-shaped fixing rod; wherein the first fixing ring and the second fixing ring are the same size, and the extrusion member includes a nut threadedly connected to the outer wall of the U-shaped fixing rod, the nut being in contact with the first fixing ring; wherein the nut is hexagonal in shape.

[0010] Furthermore, the compression assembly includes a spring three sleeved on the outer wall of the U-shaped fixing rod, the rear side of the spring three being fixedly connected to the fixing ring two, the front side of the spring three being fixedly connected to the fixing ring one, and an extrusion member being provided on the U-shaped fixing rod; wherein, the fixing ring one is in a compressed state.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting up an installation section, the threaded hollow rod and the installation rod are initially fixed during installation. Simultaneously, pulling the installation rod causes the threaded hollow rod to move upwards, stretching and storing energy in spring one, while the sliding rod compresses spring two and temporarily disengages from its limit position. After the installation rod is tightened, the restoring force of spring one pulls the threaded hollow rod and the installation rod downwards to reset. At this point, the sliding rod re-enters the two, forming a mechanical lock. The rotation of the installation rod is restricted through the dual action of threaded fastening and sliding rod limiting. Removal only requires pulling the threaded hollow rod again to disengage the sliding rod from its limit position, thus releasing the lock. This convenient operation effectively prevents the threads of the installation rod from loosening due to vibration, low-temperature stress, etc., structurally preventing the detector from falling off and improving the stability and safety of installation in cryogenic environments.

[0013] 2. By setting up a fixing part, with the U-shaped fixing rod as the core load-bearing structure, the components are nested in the order of "fixing plate one → fixing ring two → fixing ring one → spring three". Then, through the threaded engagement of the nut and the U-shaped fixing rod, all nested components are driven to gradually approach the outer wall of the pipe. When fixing plate one contacts the pipe, the nut is tightened. At this time, the axial pressure of the nut will directly act on spring three, putting it in a compressed and energy-storing state. The compressed spring three will continuously generate a reverse pre-tightening force on fixing ring one, fixing ring two and fixing plate one, firmly pressing fixing plate one onto the pipe surface. At the same time, the elastic force of the spring will also act on the nut, counteracting the loosening tendency caused by vibration, low temperature stress, etc., forming a double fixation of "threaded fastening + spring pre-compression", ensuring the long-term stability of the connection between the U-shaped fixing rod and the pipe, and avoiding the risk of displacement or falling of the detection device caused by the loosening of the fixing structure.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] Please see Figure 1-5 As shown, this utility model is a fixed bracket for a cryogenic process gas detection device, including a U-shaped fixing rod 111 and a detector 112 disposed above the U-shaped fixing rod 111. It also includes: a mounting part 2, which is mounted on the U-shaped fixing rod 111; and two fixing parts 3, both of which are disposed on the U-shaped fixing rod 111.

[0025] The mounting part 2 includes a connecting assembly 21, which is mounted on a U-shaped fixing rod 111; and a limiting assembly 22, which is disposed on the U-shaped fixing rod 111. The connecting assembly 21 includes a fixing plate 211 disposed on the U-shaped fixing rod 111. A connecting hollow rod 212 is fixedly connected to the front side of the fixing plate 211. A fixing block 213 is fixedly connected to the front side of the connecting hollow rod 212. A threaded hollow rod 214 is slidably connected to the inner wall of the fixing block 213. An installation rod 215 is threadedly connected to the inner wall of the threaded hollow rod 214. The inner wall of the threaded hollow rod 214 is threaded. The detector 112 is fixedly connected to the installation rod 215. The limiting assembly 22 includes a spring 221 disposed in the fixing block 213. The bottom of the spring 221 is connected to the fixing block 213. The fixed block 213 is fixedly connected, and the top of the spring 221 is fixedly connected to the threaded hollow rod 214. A slide rod 222 is provided inside the connecting hollow rod 212. A fixing plate 223 is fixedly connected to the rear side of the slide rod 222. An elastic element is provided on the slide rod 222. The slide rod 222 extends into the mounting rod 215. The elastic element includes a spring 224 sleeved on the outer wall of the slide rod 222. The rear side of the spring 224 is fixedly connected to the fixing plate 223, and the front side of the spring 224 is fixedly connected to the connecting hollow rod 212. The spring 224 is initially in a natural state. By setting the mounting part 2, the threads of the mounting rod are effectively prevented from loosening due to vibration, low temperature stress, etc., thus structurally preventing the detector from falling off and improving the stability and safety of installation in a cryogenic environment.

[0026] The fixing part 3 includes a sleeve assembly 31, which is mounted on the U-shaped fixing rod 111; and a compression assembly 32, which is disposed on the U-shaped fixing rod 111. Both the sleeve assembly 31 and the compression assembly 32 are located on the U-shaped fixing rod 111. The sleeve assembly 31 includes a first fixing ring 311 slidably connected to the outer wall of the U-shaped fixing rod 111, and a second fixing ring 312 slidably connected to the outer wall of the U-shaped fixing rod 111. The first fixing ring 311 and the second fixing ring 312 are of the same size. The compression component includes a nut 32 threadedly connected to the outer wall of the U-shaped fixing rod 111. 2. Nut 322 contacts the fixing ring 311; wherein, nut 322 is hexagonal in shape, and compression assembly 32 includes spring 321 sleeved on the outer wall of U-shaped fixing rod 111. The rear side of spring 321 is fixedly connected to fixing ring 312, and the front side of spring 321 is fixedly connected to fixing ring 311. A compression member is provided on U-shaped fixing rod 111; wherein, fixing ring 311 is in a compressed state. By setting fixing part 3, the long-term stability of U-shaped fixing rod and pipeline connection is ensured, and the risk of detection device displacement or falling caused by loosening of fixing structure is avoided.

[0027] A specific application of this embodiment is as follows: In use, the U-shaped fixing rod 111 is first fixed to the pipe. During fixing, the fixing plate 211 is first placed on the U-shaped fixing rod 111. Then, the fixing ring 312, the fixing ring 311, and the spring 321 are placed on the U-shaped fixing rod 111. Next, the nut 322 is threaded onto the U-shaped fixing rod 111. Then, the nut 322 is rotated, causing the nut 322, along with the fixing ring 311, fixing ring 312, spring 321, and fixing plate 211, to move closer to the outer wall of the pipe. As they approach, they will contact the fixing plate 211. After contact, the nut 322 is tightened, compressing the spring 321. This compression prevents the nut 322 from loosening after installation. After the fixing plate 211 is installed, the mounting rod 215 is installed. During installation, the mounting rod 215 is threaded onto the threaded hollow rod 214. First, insert the mounting rod 215 slightly into the threaded hollow rod 214, then pull the mounting rod 215. As the mounting rod 215 is pulled, the threaded hollow rod 214 will also move upwards. At this time, the spring 221 will be stretched. When the threaded hollow rod 214 moves upwards, it will push the sliding rod 222 outwards. After the sliding rod 222 is compressed, it will stretch the spring 224 along with the fixing plate 223. After the sliding rod 222 disengages from the spring 224, tighten the screw. After tightening the mounting rod 215, loosen the mounting rod 215. At this time, both the threaded hollow rod 214 and the mounting rod 215 will be pulled downward by the spring 221. After the threaded hollow rod 214 returns to its original position, the slide rod 222 will extend into the mounting rod 215 and the threaded hollow rod 214 again to limit the rotation of the mounting rod 215. This will prevent the mounting rod 215 and the detector 112 from falling off. To remove them, simply pull out the threaded hollow rod 214 again.
