Description

Technical Field

[0001] The invention relates to the technical field of stainless steel pipe assembly, and more specifically, to a steel wire mesh reinforced steel-plastic composite pipe assembly system and an assembly process thereof. Background Art

[0002] Steel wire mesh reinforced steel-plastic composite pipe is a high-performance composite pipe that combines the corrosion resistance of stainless steel pipes with the wear resistance and flexibility of thermoplastics. This pipe is usually composed of an inner layer of stainless steel pipe and an outer layer of thermoplastics, with a steel wire reinforcement layer in the middle to improve its overall strength and stability. With such excellent performance, steel-plastic composite pipes are widely used in various fields such as oil and natural gas transportation, industrial and mining pipes, drinking water pipes, drainage pipes, etc.

[0003] In the production process of steel wire mesh reinforced steel-plastic composite pipes, it is necessary to first form a stainless steel pipe by curling and butt welding the stainless steel strip, and then assemble the stainless steel pipe with the PE pipe so that the stainless steel pipe can smoothly enter the PE pipe to complete the production. In order to ensure that the stainless steel pipe and the PE pipe can be assembled smoothly, the weld on the stainless steel pipe needs to be fully cooled before assembly. Therefore, in the prior art, the spiral welding production of stainless steel pipes and the subsequent assembly process are generally carried out in a classified manner, but this assembly method will undoubtedly greatly reduce the production efficiency of the assembly of steel wire mesh reinforced steel-plastic composite pipes.

[0004] Therefore, it is necessary to assemble the stainless steel pipe with the PE pipe directly after the welding is completed. However, the weld of the stainless steel pipe contacts the PE pipe, causing the PE pipe to melt, making it impossible for the stainless steel pipe to completely enter the PE pipe. At the same time, during the assembly of the PE pipe, the inner diameter of the end of the PE pipe is consistent with the outer diameter of the stainless steel pipe, which also makes it difficult for the stainless steel pipe to enter the PE pipe. If pressure is applied to the stainless steel pipe, although the stainless steel pipe can be pressed into the PE pipe, the integrity of the shape of the end of the PE pipe will be destroyed. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a wire mesh reinforced steel-plastic composite pipe assembly system and an assembly process thereof, which can be directly assembled with a PE pipe after a stainless steel pipe is welded, thereby improving the assembly efficiency, avoiding hot melting of the weld and the PE pipe during the assembly process, and avoiding damage to the end of the PE pipe.

When expanding the hole, the two sliding parts slide inside the expanding groove. In the process of moving away from each other, the two expanding arc plates are simultaneously driven away from each other, so that the PE pipe abutting against it is expanded by the expanding arc plate, so that the inner diameter of the PE pipe end is slightly larger than the outer diameter of the spiral welded stainless steel pipe, which facilitates the spiral welded stainless steel pipe to enter the interior of the PE pipe to complete the assembly.

[0018] The wire mesh reinforced steel-plastic composite pipe assembly method, according to the wire mesh reinforced steel-plastic composite pipe assembly system described above, comprises the following steps:

While ensuring that the spiral welded stainless steel pipe can smoothly enter the PE pipe to complete the assembly, it can also effectively avoid the problem of deformation and damage caused by the spiral welded stainless steel pipe squeezing the PE pipe end during the assembly process.

[0028] 3. After the spiral welded stainless steel pipe is welded, the weld on it is first cooled down by the cooling unit, and then the end of the PE pipe is kept in an open state with the cooperation of the hole expansion unit and the docking assembly unit, so that the spiral welded stainless steel pipe can directly enter the PE pipe to complete the assembly, thereby realizing the direct assembly of the spiral welded stainless steel pipe with the PE pipe after welding, effectively improving the assembly efficiency of the PE pipe and the spiral welded stainless steel pipe.

[0049] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0050] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0051] See also Figure 1-13 , the present invention provides the following technical solutions:

[0052] For example, see Figure 1-6 , including a base 1, a welding unit 2 and a cooling unit 3. The base 1 includes a horizontally arranged assembly base 11 and a welding base 12. The assembly base 11 and the welding base 12 are coaxially arranged, and the height of the assembly base 11 is higher than the height of the welding base 12. The cooling unit 3 is installed on the top of the assembly base 11, and the welding unit 2 is installed on the top of the welding base 12. A spiral welded stainless steel pipe 7 is placed on the top of the welding unit 2. After the spiral welded stainless steel pipe 7 is welded at the welding unit 2, it can enter the cooling unit 3 to cool the weld on the spiral welded stainless steel pipe 7.

[0053] See also Figure 1-6The welding unit 2 includes a welding base assembly 21 installed on the top of the welding base 12 and a spiral welding assembly 22 arranged vertically on the welding base 12. The spirally welded stainless steel pipe 7 can be placed on the top of the welding base assembly 21, and the spirally welded stainless steel pipe 7 is welded with the cooperation of the spiral welding assembly 22. The welding base assembly 21 includes a base 211 installed on the top of the welding base 12, and an active rotation module 212 and an auxiliary rotation module 213 are installed on the top of the base 211 along its length direction. The active rotation module 212 is arranged on the side close to the cooling unit 3, and the auxiliary rotation module 213 is arranged on the side away from the cooling unit 3. The spirally welded stainless steel pipe 7 is placed on the top of the active rotation module 212 and the auxiliary rotation module 213, thereby driving the spirally welded stainless steel pipe 7 to rotate, so as to facilitate the spiral welding of the spirally welded stainless steel pipe 7.

[0054] See also Figure 1-6 The active rotating module 212 includes a main rotating frame 2121 installed on the top of the base 211, and two main rotating wheels 2122 are rotatably installed on the main rotating frame 2121. A driving motor 2123 is installed on the main rotating frame 2121, and the output end of the driving motor 2123 is connected to gears respectively adapted to the shapes of the two main rotating wheels 2122, and the driving motor 2123 can drive the two main rotating wheels 2122 to rotate through the gears. The auxiliary rotating module 213 includes an auxiliary rotating frame 2131 installed on the top of the base 211, and two auxiliary rotating wheels 2132 are rotatably installed on the auxiliary rotating frame 2131. A spiral welded stainless steel pipe 7 can be placed between the two main rotating wheels 2122 and the two auxiliary rotating wheels 2132. When the driving motor 2123 drives the two main rotating wheels 2122 to rotate, it can synchronously drive the spiral welded stainless steel pipe 7 and the two auxiliary rotating wheels 2132 to rotate. With the cooperation of the two main rotating wheels 2122 and the two auxiliary rotating wheels 2132, the spiral welded stainless steel pipe 7 can be rotated evenly, making it convenient for the spiral welding assembly 22 to spirally weld the spiral welded stainless steel pipe 7.

[0055] See also Figure 1-6The spiral welding assembly 22 includes a welding frame 221 arranged at the top of the vertical welding base 12, and a matching frame 223 is installed at the end of the welding frame 221. The matching frame 223 is installed on the top of the auxiliary rotating module 213, and a welding cylinder 222 is installed on the top. Two matching rotating wheels 224 are rotatably installed on the inner wall of the matching frame 223, and a welding gun 225 is installed on the outer wall. The expansion and contraction of the welding cylinder 222 can drive the matching frame 223 to move in the vertical direction, and finally make the two matching rotating wheels 224 inside the matching frame 223 abut against the spiral welded stainless steel pipe 7, and assist the spiral welded stainless steel pipe 7 from the top, so as to facilitate the spiral welded stainless steel pipe 7 to rotate evenly. After the two matching rotating wheels 224 abut against the spiral welded stainless steel pipe 7, the welding gun 225 on the side wall of the matching frame 223 can continuously weld the side wall of the spiral welded stainless steel pipe 7 during the rotation of the spiral welded stainless steel pipe 7, and complete the spiral welding of the spiral welded stainless steel pipe 7.

[0056] See also Figure 1-6 The cooling unit 3 includes a cooling rack 31 installed on the top of the assembly base 11. The cooling rack 31 is arranged vertically on the assembly base 11 and has a cooling outer sleeve 32 installed inside. The cooling outer sleeve 32 is arranged along the length direction of the assembly base 11 and is arranged as a hollow cylindrical structure. A cooling inner sleeve 33 is arranged inside the cooling outer sleeve 32, and the cooling inner sleeve 33 is arranged as a hollow cylindrical structure with a diameter smaller than the cooling outer sleeve 32. The cooling inner sleeve 33 is arranged as a hollow cylindrical structure with an inner diameter that matches the diameter of the spiral welded stainless steel pipe 7. The spiral welded stainless steel pipe 7 can enter the cooling inner sleeve 33 after completion. Several groups of water cooling pipes 34 are arranged around the cooling outer sleeve 32 and the cooling inner sleeve 33. The water cooling pipes 34 are arranged along the length direction of the cooling outer sleeve 32, and cold water can be passed into the interior thereof to cool down the weld on the spiral welded stainless steel pipe 7. A heat dissipation hole 35 is provided on the top of the cooling outer pipe sleeve 32 . When the water cooling pipe 34 cools the spiral welded stainless steel pipe 7 , the excess heat generated can be discharged through the heat dissipation hole 35 .

[0057] Specifically, after the spiral welded stainless steel pipe 7 is welded, it continues to enter the cooling inner pipe sleeve 33, and the cold water introduced into the water-cooling pipe 34 is used to cool the spiral welded stainless steel pipe 7. Before the spiral welded stainless steel pipe 7 is assembled, the temperature of the weld on the spiral welded stainless steel pipe 7 is reduced, thereby effectively avoiding the problem that during the assembly process of the spiral welded stainless steel pipe 7, the weld is in contact with the PE pipe 6 and generates hot melting, resulting in adhesion between the PE pipe 6 and the spiral welded stainless steel pipe 7, and ultimately causing the spiral welded stainless steel pipe 7 to be unable to completely enter the PE pipe 6 to complete the assembly.

[0058] For example 2, please refer to Figure 1-2 and Figure 7-13, the present embodiment 2 is improved as follows on the basis of the embodiment 1, although the cooling unit 3 can cool down the weld on the spiral welded stainless steel pipe 7 after the welding is completed, thereby avoiding the situation where the spiral welded stainless steel pipe 7 contacts and sticks to the PE pipe 6. However, when the PE pipe 6 is assembled with the spiral welded stainless steel pipe 7, because the inner diameter of the PE pipe 6 is consistent with the outer diameter of the spiral welded stainless steel pipe 7, there is still a problem that the spiral welded stainless steel pipe 7 cannot smoothly pass through the end of the PE pipe 6 to enter its interior for assembly during the assembly process. If the method of applying external force to the spiral welded stainless steel pipe 7 is adopted during assembly, although the assembly of the spiral welded stainless steel pipe 7 and the PE pipe 6 can be completed, the end of the PE pipe 6 will be squeezed by the spiral welded stainless steel pipe 7 to cause deformation, and even damage will occur in severe cases. Therefore, it is necessary to set a hole expansion unit 4 and a docking assembly unit 5. With the cooperation of the hole expansion unit 4 and the docking assembly unit 5, on the basis of completing the assembly of the PE pipe 6 and the spiral welded stainless steel pipe 7, the problem of deformation and damage caused by the squeezing of the spiral welded stainless steel pipe 7 on the end of the PE pipe 6 is effectively avoided.

[0059] See also Figure 1-2 and Figure 7-13 The top of the assembly base 11 is sequentially installed with a cooling unit 3, a hole expansion unit 4 and a docking assembly unit 5. After the spiral welded stainless steel pipe 7 passes through the cooling unit 3 to complete the cooling of the weld, the hole expansion unit 4 expands the diameter of the end of the PE pipe 6 clamped on the docking assembly unit 5. When the docking assembly unit 5 drives the PE pipe 6 to approach the spiral welded stainless steel pipe 7, the spiral welded stainless steel pipe 7 gradually enters the interior of the PE pipe 6 to complete the assembly.

[0060] See also Figure 1-2 and Figure 7-13 The hole expansion unit 4 includes a hole expansion frame 41 installed on the top of the assembly base 11. The hole expansion frame 41 is arranged vertically on the assembly base 11, and a circular through hole is opened through the side wall. A hole expansion ring 42 is installed inside the hole expansion frame 41. The hole expansion ring 42 is set as a hollow cylindrical structure with a diameter consistent with the diameter of the through hole on the hole expansion frame 41, and two hole expansion slide grooves 43 are symmetrically opened on the side wall close to the clamping assembly 53. A sliding member 44 is slidably installed inside each group of hole expansion slide grooves 43, and a semi-circular hole expansion arc plate 45 whose shape is adapted to the shape of the PE pipe 6 is arranged on the sliding member 44. The two hole expansion arc plates 45 are arranged opposite to each other and are arranged on the side close to the docking assembly unit 5. The two hole expansion arc plates 45 are arranged with an inclination angle on one side close to the docking assembly unit 5, so as to facilitate the insertion into the PE pipe 6 by contacting with the inner wall of the PE pipe 6.

[0061] Before the hole is expanded, the ends of the two expansion arc plates 45 are kept in contact with the inner wall of the end of the PE pipe 6. When expanding the hole, the two sliding members 44 slide inside the expansion slot 43. In the process of moving away from each other, the two expansion arc plates 45 are synchronously driven to move away from each other, so that the expansion arc plates 45 are used to open the PE pipe 6 in contact with it, so that the inner diameter of the end of the PE pipe 6 is slightly larger than the outer diameter of the spiral welded stainless steel pipe 7, which is convenient for the spiral welded stainless steel pipe 7 to enter the PE pipe 6 to complete the assembly. By opening the two expansion arc plates 45, the inner diameter of the end of the PE pipe 6 can always be kept slightly larger than the outer diameter of the spiral welded stainless steel pipe 7 during the assembly process. While ensuring that the spiral welded stainless steel pipe 7 can smoothly enter the PE pipe 6 to complete the assembly, it can also effectively avoid the problem of deformation and damage caused by the squeezing of the spiral welded stainless steel pipe 7 during the assembly process.

[0062] See also Figure 1-2 and Figure 7-13 The docking assembly unit 5 includes an auxiliary support assembly 51 installed between the cooling unit 3 and the reaming unit 4, a push assembly assembly 52 slidably installed at the end of the assembly base 11, and a clamping assembly 53 installed on the push assembly assembly 52. ​​The auxiliary support assembly 51 can provide support for the spiral welded stainless steel pipe 7 during assembly to ensure accurate and reliable positioning of the spiral welded stainless steel pipe 7 and the PE pipe 6. The clamping assembly 53 can clamp the PE pipe 6, and then drive the clamping assembly 53 and the PE pipe 6 to move synchronously by pushing the assembly assembly 52, so that the PE pipe 6 is close to the spiral welded stainless steel pipe 7 to complete the assembly.

[0063] See also Figure 1-2 and Figure 7-13 The auxiliary support assembly 51 includes an auxiliary seat 511 installed on the top of the assembly base 11, and a first auxiliary block 512 and a second auxiliary block 513 are symmetrically arranged on the top of the auxiliary seat 511. The first auxiliary block 512 and the second auxiliary block 513 are arranged opposite to each other, and the shape of the side walls is adapted to the shape of the spiral welded stainless steel pipe 7. After the spiral welded stainless steel pipe 7 is welded, it can pass through the gap between the first auxiliary block 512 and the second auxiliary block 513 and be assembled with the PE pipe 6. The first auxiliary block 512 and the second auxiliary block 513 can provide support and limit for the spiral welded stainless steel pipe 7 during the assembly process, ensuring that the positioning of the spiral welded stainless steel pipe 7 is accurate and reliable during assembly.

[0064] See also Figure 1-2 and Figure 7-13The push assembly component 52 includes two assembly slide rails 521 arranged along the length direction of the assembly base 11, and an assembly frame 522 is slidably installed on the top of the assembly slide rail 521, and the assembly frame 522 can slide along the direction of the assembly slide rail 521. The side wall of the assembly frame 522 away from the auxiliary support component 51 is connected to the main push cylinder 523. The clamping component 53 is installed on the assembly frame 522, and the auxiliary cylinder 524 is installed on the side away from the main push cylinder 523, and the output end of the auxiliary cylinder 524 is connected to the clamping component 53. The main push cylinder 523 can be extended and retracted to drive the assembly frame 522 to slide along the direction of the assembly slide rail 521, thereby driving the clamping component 53 to move. During the movement of the clamping component 53, the auxiliary cylinder 524 can be synchronously extended and retracted to assist the sliding of the clamping component 53.

[0065] See also Figure 1-2 and Figure 7-13 The clamping assembly 53 includes a clamping frame 531 installed on the top of the assembly frame 522, and a clamping disk module 535 is installed on the side wall of the clamping frame 531. The clamping disk module 535 is arranged throughout the clamping frame 531, and a matching chain group 534 is connected to the side away from the hole expansion unit 4. The matching chain group 534 is installed inside the clamping frame 531, and the top of the matching chain group 534 is connected to the clamping motor 532 through the matching pulley 533. The clamping motor 532 can drive the matching pulley 533 to rotate, and further drive the matching chain group 534 to rotate. During the rotation of the matching chain group 534, the clamping disk module 535 can be driven to rotate synchronously.

[0066] See also Figure 1-2 and Figure 7-13 The clamping disk module 535 includes a clamping chuck 5351 that penetrates the side wall of the clamping frame 531. The clamping chuck 5351 is connected to four groups of clamping disks 5352 near the auxiliary support assembly 51.
