[0002] Chemical products require the use of chemical pipelines during transportation. These pipelines are connected by multiple bolts, but the bolts at the connection points of two pipelines are easily exposed to water, leading to corrosion. Furthermore, the two pipelines may become misaligned due to impacts from external objects, resulting in leakage of the chemical products inside. Therefore, a new type of safety device for chemical transportation pipelines is proposed. Utility Model Content

[0004] To achieve the above objectives, this utility model adopts the following technical solution, including a fixed base, a support plate fixedly installed on the top of the fixed base, the interior of the support plate being hollow for pipes to pass through, an isolation protective cover provided between the two support plates, the interior of the isolation protective cover being hollow and a sealing plate being installed at the bottom by bolts, an adjustment cavity opened inside the support plate, the adjustment cavity communicating with the top surface of the support plate, an installation horizontal plate extending outward from the bottom surface of the adjustment cavity provided, an adjustment stud fixedly installed at the center of the top of each of the two installation horizontal plates, a fastening plate snapped between the two adjustment studs, the fastening plate being movably installed inside the adjustment cavity by the two adjustment studs, and a snap-fit ​​pressure plate with an arc-shaped structure provided at the center of the bottom of the fastening plate, the bottom surface of the snap-fit ​​pressure plate being bonded with an anti-slip layer.

[0005] Furthermore, both ends of the fastening plate are provided with fitting holes. After the fastening plate is fitted onto the outside of the adjusting stud, the fastening plate is pushed into the interior of the adjusting cavity by rotating the nut.

[0006] Furthermore, the top surface of the support plate is provided with an access slot, and two locking studs for positioning are fixedly installed inside the access slot. The top of the locking studs extends to the outside of the support plate for fitting nuts.

[0019] A new type of safety device for chemical pipeline transportation, such as Figures 1 to 4 As shown, the device includes a fixed base 1, a support plate 2 fixedly mounted on the top of the fixed base 1, the interior of the support plate 2 being hollow for pipes to pass through, an isolation protective cover 3 being provided between the two support plates 2, the interior of the isolation protective cover 3 being hollow and a sealing plate being installed at the bottom by bolts, an adjustment cavity 5 being provided inside the support plate 2, the adjustment cavity 5 being connected to the top surface of the support plate 2, an installation horizontal plate 8 extending outward from the bottom surface of the adjustment cavity 5 being provided, an adjustment stud 9 being fixedly mounted at the center of the top of each of the two installation horizontal plates 8, a fastening plate 10 being snapped between the two adjustment studs 9, a curved snap-fit ​​pressure plate 12 being provided at the center of the bottom of the fastening plate 10, a rubber pad for anti-slip being adhered to the bottom surface of the snap-fit ​​pressure plate 12, and the fastening plate 10 being movably mounted inside the adjustment cavity 5 by the two adjustment studs 9.

[0020] Both ends of the fastening plate 10 have internal fitting holes 11. After the fastening plate 10 is fitted onto the outside of the adjusting stud 9, a nut is fitted onto the outside of the corresponding adjusting stud 9. By rotating the fitted nut, the fastening plate 10 is lowered as a whole. The bottom surface of the internal opening of the support plate 2 is provided with two symmetrical anti-slip pads 4. After the pipe passes through the inside of the support plate 2, it fits against the anti-slip pads 4. After the pipe passes through the support plate 2, during the descent of the fastening plate 10, the clamping pressure plate 12 and the anti-slip pads 4 come into contact with and press against the surface of the pipe, so that the pipe is not easy to slip after being clamped.

[0021] The top surface of the support plate 2 is provided with an access slot 6. Two locking studs 7 for positioning are fixedly installed inside the access slot 6. The top of the locking studs 7 extends to the outside of the support plate 2 for fitting nuts. The front and rear sides of the top of the isolation protective cover 3 are fixedly installed with limiting plates 13 corresponding to the size inside the access slot 6. The limiting plates 13 are provided with mounting holes 14 corresponding to the size of the locking studs 7. After the support plate 2 is installed on both sides of the flange ring of the pipeline, the isolation protective cover 3 is fitted onto the outside of the pipeline and the position of the isolation protective cover 3 is adjusted so that the limiting plates 13 on both sides of the isolation protective cover 3 are engaged into the access slots 6 corresponding to the top of the support plate 2. After the locking studs 7 pass through the inside of the mounting holes 14, the nuts are used to fit on the top of the locking studs 7 and rotate to lock them. The isolation protective cover 3 is restricted to be installed outside the flange ring connection by the two support plates 2.

[0022] The working principle of this utility model:

[0023] By setting up a support plate 2 for pipe installation, adjusting studs 9 are fixed on the mounting plates 8 extending from both sides of the support plate 2. Then, fastening plates 10 are inserted into the adjustment cavity 5. The two ends of the adjustment cavity 5 are fitted onto the outside of the adjusting studs 9. Nuts are fitted onto the top of the adjusting studs 9 and rotated. Then, the pipe is passed through the inside of the support plate 2. The positions of the two sets of support plates 2 are adjusted to the pipe flange ring connection. Then, the nuts fitted onto the top of the adjusting studs 9 are rotated to drive the fastening plates 10 down. The friction increases after the pipe surface comes into contact with the clamping pressure plate 12 and the two anti-slip pads 4. The two sets of devices are installed on both sides of the pipe flange ring connection. After clamping the pipe, it is prevented from sliding relative to the pipe during the support process, thus improving the overall fixing effect of the support plate 2.

[0024] By installing an isolation protective cover 3 for additional protection, and after two sets of support plates 2 are installed on both sides of the flange ring connection of the pipeline, the entire isolation protective cover 3 is erected between the two support plates 2. The limiting plates 13 on both sides of the isolation protective cover 3 are inserted into the corresponding access slots 6 and then fitted onto the locking studs 7. Nuts are then fitted onto the top of the locking studs 7 for locking. After that, the sealing plate at the bottom of the isolation protective cover 3 is installed on the outside of the reserved insertion hole at the bottom of the isolation protective cover 3, so that the isolation protective cover 3 forms a complete box. The isolation protective cover 3 wraps around the flange ring connection of the pipeline, reducing the contact with external moisture during long-term use and reducing the corrosion of the flange ring connection. At the same time, under the isolation protection of the isolation protective cover 3, external impacts will not affect the pipeline connection, thus achieving a good protective effect.
