Description

Technical Field

[0001] This utility model relates to the field of hazardous chemical transportation technology, and in particular to a quick-connect hazardous chemical pipeline. Background Technology

[0002] After petrochemical products are transported to the dock by large oil tankers, they need to be transported from the dock to refineries or oil depots via hazardous chemical pipelines. The pipelines used to transport petrochemical products are usually assembled from individual pipes connected by flanges. In traditional technology, the pipelines are usually transported to the designated location by heavy equipment, and then the flanges of two pipelines are joined together manually. However, when joining the flanges of two pipelines, the distance between the two pipelines needs to be controlled. If the distance is too far, it is difficult to join them together; if the two pipelines overlap, it is difficult to join them together. Therefore, the flange joining of two pipelines consumes a lot of time, resulting in a technical problem of low efficiency in pipeline joining. Utility Model Content

[0003] Therefore, it is necessary to provide a quick-connect hazardous chemical pipeline to address the technical problem of low efficiency in the docking and assembly of pipelines.

[0004] A quick-connect hazardous chemical pipeline includes: a combination pipe, a pipe pressing mechanism, a hook mechanism, and a connecting pipe. The combination pipe is connected to the pipe pressing mechanism and the hook mechanism. The pipe pressing mechanism includes an adapter arm and a pawl. The adapter arm is movably connected to the combination pipe. The pawl is connected to the adapter arm and has a groove. The hook mechanism includes a locking handle and a tensioning assembly. The locking handle is installed on the combination pipe and is used to drive the tensioning assembly to move towards the combination pipe. The tensioning assembly is engaged with the pawl. The connecting pipe includes a connecting flange and a connecting pipe body. The connecting flange abuts against the pawl, and the connecting pipe body is inserted into the groove.

[0005] The quick-connect hazardous chemical pipeline has a first use state and a second use state. When the quick-connect hazardous chemical pipeline is in the first use state, the pipe pressing mechanism is separated from the connecting pipe, and the hook mechanism is separated from the pipe pressing mechanism. When the quick-connect hazardous chemical pipeline is in the second use state, the connecting pipe body is inserted into the slot, the tensioning assembly is engaged with the claw, and the locking handle drives the tensioning assembly to move towards the combined pipe, so as to control the tensioning assembly to abut against the claw, and drive the connecting flange to abut against the claw.

[0006] In one embodiment, the combined pipe includes a combined flange, a combined pipe body, a pipe clamping bracket, and a hook bracket. The combined flange abuts against the docking flange, the combined pipe body is connected to the pipe clamping bracket and the hook bracket, the pipe clamping bracket is movably connected to the adapter arm, and the hook bracket is connected to the locking handle.

[0007] In one embodiment, the combined flange is provided with a first slot, the mating flange is provided with a second slot corresponding to the position of the first slot, and the adapter arm is inserted into the first slot and the second slot.

[0008] In one embodiment, the combined flange is provided with a through hole, and the mating flange is provided with a connection hole corresponding to the position of the through hole.

[0009] In one embodiment, the adapter arm is provided with a strip groove, which is movably connected to the combined pipe.

[0010] In one embodiment, the claw includes a claw hand and a lug, the claw hand having the claw groove, and the lug engaging with the tensioning assembly.

[0011] In one embodiment, the locking handle includes an eccentric block and a bushing. One end of the eccentric block is rotatably connected to the combined tube, and the other end of the eccentric block is rotatably connected to the bushing. The bushing is connected to the tensioning assembly.

[0012] In one embodiment, the locking handle further includes a lever connected to the end of the eccentric block away from the combined tube.

[0013] In one embodiment, the tensioning assembly includes an adapter rod and a hook, the adapter rod being connected to the locking handle, the hook being connected to the adapter rod, and engaging with the pawl.

[0014] In one embodiment, the latch includes a triangular hook and an adapter block, the triangular hook engaging with the pawl, and the adapter block being threadedly connected to the adapter rod.

[0015] The beneficial effects of the quick-connect hazardous chemical pipeline provided in this application are as follows: the clamping mechanism's claws are inserted into the body of the connecting pipe, and the tensioning component of the hook mechanism is engaged with the claws. The locking handle controls the tensioning component to hold against the claws, and drives the connecting flange to hold against the claws. This method facilitates the control of the connection between the combined pipe and the connecting pipe at a preset distance through the cooperation of the clamping mechanism and the hook mechanism, thereby increasing the required interval distance between the combined pipe and the connecting pipe during assembly, reducing the placement time of the two conveying pipelines, and reducing the overall time consumption during connection and assembly, thus improving the assembly efficiency of the hazardous chemical pipeline.

[0030] like Figures 1 to 2 As shown, it is the quick-connect hazardous chemical pipeline 100 of this utility model, used for transporting hazardous chemicals.

[0031] like Figure 1 As shown, the quick-connect hazardous chemical pipeline 100 includes: a combination pipe 10, a pipe pressing mechanism 20, a hook mechanism 30, and a connecting pipe 40. The combination pipe 10 is used to install the pipe pressing mechanism 20 and the hook mechanism 30. The pipe pressing mechanism 20 is used to connect with the connecting pipe 40. The hook mechanism 30 is used to pull the pipe pressing mechanism 20 toward the combination pipe 10 to drive the connecting pipe 40 to abut against the combination pipe 10, thereby achieving the docking of the combination pipe 10 and the connecting pipe 40. This reduces the placement time of the combination pipe 10 and the connecting pipe 40, thereby reducing the overall time consumption during docking and assembly, and achieving the purpose of improving the assembly efficiency of the hazardous chemical pipeline.

[0032] The following text, combined with Figures 1 to 2 Further explanation is provided regarding the aforementioned quick-connect hazardous chemical pipeline 100.

[0033] like Figure 1 As shown, the combined pipe 10 is connected to the pipe pressing mechanism 20 and the hook mechanism 30. The pipe pressing mechanism 20 includes an adapter arm 21 and a claw 22. The adapter arm 21 is movably connected to the combined pipe 10. The claw 22 is connected to the adapter arm 21 and is provided with a groove 221. The hook mechanism 30 includes a locking handle 31 and a tensioning assembly 32. The locking handle 31 is installed on the combined pipe 10 and is used to drive the tensioning assembly 32 to move towards the combined pipe 10. The tensioning assembly 32 is engaged with the claw 22. The connecting pipe 40 includes a connecting flange 41 and a connecting pipe body 42. The connecting flange 41 abuts against the claw 22, and the connecting pipe body 42 is inserted into the groove 221.

[0034] To improve the connection stability between the combined pipe 10 and the connecting pipe 40, such as Figure 1As shown, the combined pipe 10 includes a combined flange 11, a combined pipe body 12, a crimping bracket 13, and a hook bracket 14. The combined flange 11 abuts against the connecting flange 41. The combined pipe body 12 is connected to the crimping bracket 13 and the hook bracket 14. The crimping bracket 13 is movably connected to the adapter arm 21. The hook bracket 14 is connected to the locking handle 31. The abutting between the combined flange 11 and the connecting flange 41 helps to increase the contact area between the combined pipe 10 and the connecting pipe 40, thereby improving the connection stability between the combined pipe 10 and the connecting pipe 40.

[0035] Furthermore, such as Figures 1 to 2 As shown, the combined flange 11 is provided with a first slot 111, and the mating flange 41 is provided with a second slot 411 corresponding to the position of the first slot 111. The adapter arm 21 is inserted into the first slot 111 and the second slot 411. By using the method of inserting the adapter arm 21 into the first slot 111 and the second slot 411, the adapter arm 21 can restrict the relative position of the combined flange 11 and the mating flange 41 through the first slot 111 of the combined flange 111 and the second slot 411 of the mating flange 41, thereby achieving the purpose of improving the docking accuracy of the combined pipe 10 and the mating pipe 40.

[0036] To improve the sealing performance of the connection between the combined pipe 10 and the connecting pipe 40, such as Figure 1 As shown, the combined flange 11 is provided with a through hole 112, and the mating flange 41 is provided with a connection hole 412 corresponding to the position of the through hole 112. The through hole 112 of the combined flange 11 is threaded through the bolts and connected to the connection hole 412 of the mating flange 41. This helps to strengthen the connection and fit of the combined pipe 10 and the mating pipe 40, thereby improving the sealing performance of the connection between the combined pipe 10 and the mating pipe 40.

[0037] like Figure 1 As shown, the adapter arm 21 is provided with a strip groove 211, which is movably connected to the pressure tube bracket 13 of the combined tube 10. Specifically, the claw 22 includes a claw hand 222 and a lug 223. The claw hand 222 is provided with a groove 221, and the lug 223 is fastened to the tensioning component 32.

[0038] like Figures 1 to 2 As shown, the locking handle 31 includes an eccentric block 311 and a bushing 312. One end of the eccentric block 311 is rotatably connected to the combined tube 10, and the other end of the eccentric block 311 is rotatably connected to the bushing 312. The bushing 312 is connected to the tensioning assembly 32. The locking handle 31 also includes a lever 313, which is connected to the end of the eccentric block 311 away from the combined tube 10. By connecting the lever 313 to the end of the eccentric block 311 away from the combined tube 10, the ease of operation of the eccentric block 311 is increased, and the force exerted by the eccentric block 311 when rotating around the combined tube 10 can be effectively reduced, thereby improving the locking convenience of the locking handle 31.

[0039] like Figure 1 As shown, the tensioning assembly 32 includes an adapter rod 321 and a hook 322. The adapter rod 321 is connected to the locking handle 31, and the hook 322 is connected to the adapter rod 321 and is engaged with the pawl 22. The hook 322 includes a triangular hook 323 and an adapter block 324. The triangular hook 323 is engaged with the pawl 22, and the adapter block 324 is threadedly connected to the adapter rod 321.

[0040] like Figures 1 to 2 As shown, the quick-connect hazardous chemical pipeline 100 has a first usage state and a second usage state, such as... Figure 1 As shown, when the quick-connect hazardous chemical pipeline 100 is in its first operating state, the crimping mechanism 20 separates from the connecting pipe 40, and the hook mechanism 30 separates from the crimping mechanism 20, as... Figure 2 As shown, when the quick-connect hazardous chemical pipeline 100 is in the second use state, the connecting pipe body 42 is inserted into the slot 221, the tensioning assembly 32 is fastened to the claw 22, and the locking handle 31 drives the tensioning assembly 32 to move towards the combined pipe 10, so as to control the tensioning assembly 32 and the claw 22 to abut against each other, and drive the connecting flange 41 and the claw 22 to abut against each other.

[0041] When using the quick-connect hazardous chemical pipeline 100 provided in this application: the connecting pipe 40 is placed within a preset distance of the combined pipe 10, and the adapter arm 21 of the control pipe pressing mechanism 20 moves around the pipe pressing bracket 13 until the groove 221 of the claw 22 is inserted into the connecting pipe body 42 of the connecting pipe 40. Then, the hook 322 of the control hook mechanism 30 is engaged with the lug 223 of the claw 22. Then, the eccentric block 311 is rotated by the lever 313 of the locking handle 31, so that the eccentric block 311 drives the adapter rod 321 of the tensioning assembly 32 to drive the hook 322 to move towards the combined pipe body 12 of the combined pipe 10 until the combined flange 11 is connected to the docking flange 41. Finally, the quick-connect hazardous chemical pipeline 100 is assembled by threading through the through hole 112 of the combined flange 11 and the connection hole 412 of the docking flange 41.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
