A steel strip corrugated pipe connection device

Abstract

This invention relates to the field of pipe connection technology, and particularly to a steel strip corrugated pipe connection device. The device allows a second corrugated forming mechanism to extrude molten liquid into the inner cavity of the insertion section to form a corrugated joint steel strip ring that connects to the steel strip corrugated section. The heat generated during the extrusion of the corrugated joint steel strip ring is used to heat the insertion section and the joint section. This allows the invention to convert the connection section and insertion section of the steel strip corrugated pipe into a corrugated structure during use. Consequently, this invention can produce a steel strip corrugated pipe structure that exhibits full corrugation in use. This solves the technical problem that while traditional connection methods using plugs or joints at both ends of the pipe section can achieve the connection function, they prevent bending and deformation at the connection points of the corrugated pipe sections, affecting the routing of the corrugated pipe at corners and other locations.

Description

Technical Field

[0001] This invention relates to the field of pipe connection technology, and in particular to a steel strip corrugated pipe connection device. Background Technology

[0002] A bellows is a tubular elastic sensitive element made of foldable corrugated sheets connected along the folding and stretching direction.

[0003] Bellows are widely used in construction, factory production, and instrumentation, primarily as measuring elements in pressure gauges. They are elastic, converting pressure into displacement or force. Bellows have thin walls, high sensitivity, and a measurement range from tens of Pascals to tens of megapascals. Their open end is fixed, while the sealed end is free, with auxiliary helical springs or leaf springs used to increase elasticity. During operation, under internal pressure, they elongate along the length of the tube, causing a displacement at the moving end that is proportional to the pressure. They are often combined with displacement sensors to form pressure sensors that output electrical signals, and sometimes they are used as isolation elements. Because the expansion of a bellows requires a large volume change, its response speed is slower than that of a Bourdon tube. Bellows are suitable for measuring low pressure. Types include metal bellows, bellows expansion joints, bellows heat exchange tubes, diaphragm boxes, and metal flexible tubes. Materials generally include bronze, brass, stainless steel, Monel alloy, and Inconel alloy.

[0004] Corrugated pipes are typically pipe sections of a certain length, and multiple sections usually need to be assembled sequentially when using them. In existing technology, to facilitate assembly, the two ends of each pipe section are usually designed as plugs or connectors that can be inserted into each other. While this connection method achieves the function of connecting pipe sections, it prevents bending and deformation at the joints, affecting the routing of the corrugated pipe at corners and other locations. Summary of the Invention

[0005] The main objective of this invention is to provide a steel strip corrugated pipe connection device, which aims to solve the technical problem in related technologies where the connection method of setting plugs or connectors at both ends of the pipe section can achieve the connection function of the pipe section, but the traditional connection method will prevent the connection of the corrugated pipe sections from bending and deforming, affecting the routing of the corrugated pipe at corners and other positions.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a steel strip corrugated pipe connection device, wherein the steel strip corrugated pipe includes a steel strip corrugated section, one end of the steel strip corrugated section forms a connecting section, and the other end forms a plug-in section that can be plugged into and mated with the connecting section.

[0007] The steel strip corrugated pipe connecting device includes:

[0008] A first connecting mechanism is placed inside the cavity of the corrugated pipe. The first connecting mechanism includes a first mounting component and a first corrugated forming component disposed on the first mounting component. The first mounting component can drive the first corrugated forming component to move within the cavity along the length direction of the corrugated pipe.

[0009] The second connecting mechanism covers the outer periphery of the corrugated pipe. The second connecting mechanism includes a second mounting component and a second corrugated forming component disposed on the second mounting component. The second mounting component can drive the second corrugated forming component to move along the length direction of the corrugated pipe along the outer periphery of the corrugated pipe.

[0010] When the plug segment is inserted into the connecting segment, the first corrugated forming component can cooperate with the second corrugated forming component. The first corrugated forming component can extrude molten liquid into the inner cavity of the plug segment to form a corrugated joint steel strip ring connected to the corrugated steel strip segment. The heat generated when the corrugated joint steel strip ring is extruded is used to heat the plug segment and the connecting segment.

[0011] Optionally, the first corrugated forming component includes:

[0012] A first driving component is mounted on the first mounting component;

[0013] A first transmission assembly, wherein the first transmission assembly is mounted on the output end of the first driving member; and...

[0014] A first corrugated forming assembly is hinged to the first mounting component and rotates with the first transmission assembly. The first corrugated forming assembly can heat the insertion section.

[0015] The first driving member can drive the first transmission component to rotate, thereby causing the first corrugated forming component to enlarge and fit against the inner wall of the insertion section, and cooperate with the second corrugated forming component to form a corrugated structure in the insertion section.

[0016] Optionally, the first corrugated forming component includes:

[0017] A first connecting bracket, one end of which is hinged to the first mounting component, and the other end of which extends away from the first driving component;

[0018] A first adjusting bracket is rotatably mounted on the first transmission assembly;

[0019] A first corrugated component is disposed around the outer periphery of the first transmission assembly. The first corrugated component is simultaneously connected to both the first connecting bracket and the first adjusting bracket, and the first corrugated component is rotatably engaged with the first connecting bracket.

[0020] A first heating element is disposed around the outer periphery of the first corrugated forming part;

[0021] The first driving member can drive the first transmission assembly to rotate the first adjusting bracket, so that the first corrugated forming part extends and enlarges in the direction away from the first transmission assembly and fits against the inner wall of the insertion section, or retracts and decreases in the direction close to the first transmission assembly.

[0022] The first corrugated forming assembly can extrude a corrugated joint steel strip ring that is connected to the corrugated steel strip section on the inner wall of the plug section, and the heat generated when the corrugated joint steel strip ring is extruded is used to heat the plug section and the connecting section.

[0023] Optionally, the first corrugated forming component includes a plurality of first arc-shaped connecting blocks, which are arranged in annular intervals around the outer periphery of the first transmission component. A first arc-shaped connector is provided between any two adjacent first arc-shaped connecting blocks. The first arc-shaped connector is slidably engaged with the two adjacent first arc-shaped connecting blocks. The first arc-shaped connecting block is hinged to the first adjusting bracket. A first sliding groove extending along the arc length direction of the first arc-shaped connecting block is formed on the first arc-shaped connecting block. The end of the first connecting bracket away from the first mounting component is slidably engaged in the first sliding groove. The first heating element is installed on each of the first arc-shaped connecting blocks.

[0024] Optionally, there are multiple first heating elements, and the number of the first heating elements is the same as the number of the first arc-shaped connecting blocks and they are arranged in a one-to-one correspondence.

[0025] Optionally, the second corrugated forming component includes:

[0026] A plurality of second driving members are circumferentially spaced and mounted on the inner side of the second mounting component;

[0027] Multiple second transmission components are mounted on the output end of the second drive component, and the number of second transmission components is the same as that of the second drive component, and they are arranged in a one-to-one correspondence; and...

[0028] Multiple second corrugated forming components are mounted on the end of the second transmission component away from the second drive component. The number of second corrugated forming components is the same as that of the second transmission component, and they are arranged in a one-to-one correspondence.

[0029] In this configuration, multiple second driving components can simultaneously drive the corresponding second transmission components to bring the corresponding second corrugated forming components closer to and fit against the connecting segment, so as to cooperate with the first corrugated forming component to extrude the connecting segment and the plug segment into a corrugated structure.

[0030] Optionally, the second corrugated forming component includes:

[0031] A second corrugated forming component is disposed at the end of the second transmission assembly away from the second driving component. The second corrugated forming component cooperates with the first corrugated forming assembly to extrude the connecting section and the insertion section into a corrugated structure; and...

[0032] The second heating element is disposed around the outer periphery of the second corrugated forming part;

[0033] The second driving component can drive the corresponding second transmission component to move the corresponding second corrugated forming component closer to or away from the outer wall of the connecting section.

[0034] Optionally, the second corrugated part is arranged in an arc shape.

[0035] Optionally, the second corrugated part is corrugated on the side near the connecting section.

[0036] The technical solution of this invention first sets a steel strip corrugated pipe as a steel strip corrugated segment, and forms connecting segments and insertion segments that can be inserted into the connecting segments at both ends of the steel strip corrugated segment. Then, by setting a first connecting mechanism and a second connecting mechanism, the first connecting mechanism is placed inside the cavity of the corrugated pipe and the second connecting mechanism is wrapped around the outer periphery of the corrugated pipe. The first mounting component in the first connecting mechanism can drive the first corrugated forming component to move along the length direction of the corrugated pipe inside the cavity, and the second mounting component in the second connecting mechanism can drive the second corrugated forming component to move along the length direction of the corrugated pipe around the outer periphery of the corrugated pipe. When the insertion segment is inserted into the connecting segment, the first corrugated forming component can cooperate with the second corrugated forming component, and the first corrugated forming component can be inserted into the connecting segment. Molten liquid is extruded from the inner cavity of the section to form a corrugated joint steel strip ring that connects to the corrugated steel strip section. The heat generated during the extrusion of the corrugated joint steel strip ring is used to heat the plug section and the connecting section. This allows the connecting section and plug section of the corrugated steel strip pipe to be converted into a corrugated structure during use. Consequently, the present invention can produce a corrugated steel strip pipe structure that is fully corrugated in use. This invention solves the technical problem in related technologies where the connection method of setting plugs or connectors at both ends of the pipe section can achieve the connection function of the pipe section, but the traditional connection method prevents the connection of the pipe sections of the corrugated pipe from bending and deforming, affecting the routing of the corrugated pipe at corners and other positions.

[0054] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.

[0055] This invention proposes a steel strip corrugated pipe connection device and connection method.

[0056] like Figures 1 to 9 As shown, an embodiment of the steel strip corrugated pipe connection device and connection method of the present invention is presented.

[0057] In this embodiment, please refer to Figures 1-9 The steel strip corrugated pipe connecting device includes a steel strip corrugated section 01, one end of the steel strip corrugated section 01 forms a connecting section 02, and the other end forms a plug-in section 03 that can be plugged into the connecting section 02.

[0058] The steel strip corrugated pipe connection device includes:

[0059] A first connecting mechanism 100 is placed inside the cavity of a corrugated pipe. The first connecting mechanism 100 includes a first mounting component 110 and a first corrugated forming component 120 disposed on the first mounting component 110. The first mounting component 110 can drive the first corrugated forming component 120 to move within the cavity along the length direction of the corrugated pipe.

[0060] The second connecting mechanism 200 covers the outer periphery of the corrugated pipe. The second connecting mechanism 200 includes a second mounting component 210 and a second corrugated forming component 220 disposed on the second mounting component 210. The second mounting component 210 can drive the second corrugated forming component 220 to move along the length direction of the corrugated pipe on the outer periphery of the corrugated pipe.

[0061] When the insertion section 03 is inserted into the connecting section 02, the first corrugated forming component 120 can cooperate with the second corrugated forming component 220. The first corrugated forming component 120 can extrude molten liquid into the inner cavity of the insertion section 03 to form a corrugated joint steel strip ring 04 connected to the steel strip corrugated section 01. The heat generated when the corrugated joint steel strip ring 04 is extruded is used to heat the insertion section 03 and the connecting section 02.

[0062] It should be specifically and clearly stated that, in this embodiment, to facilitate the corrugated extrusion molding of the connecting section 02 and the insertion section 03, the inner walls of the example connecting section 02 and the insertion section 03 do not have steel strip structures. It should be further emphasized that the example connecting section 02 and the insertion section 03 are preferably made of polyolefin material.

[0063] In this embodiment, specifically, both the first mounting component 110 and the second mounting component 210 include a mounting platform. A walking device capable of moving on the corrugated steel strip section 01 is mounted on the mounting platform. To facilitate the corrugation forming of the connecting section 02 and the insertion section 03 by the first corrugated forming component 120 and the second corrugated forming component 220, after transporting the first corrugated forming component 120 and the second corrugated forming component 220 to their respective positions, the walking device needs to adhere to the corrugated section for fixation. Therefore, it should be specifically and clearly stated that the walking device mounted on the first mounting component 110 and the walking device mounted on the second mounting component 210 can be either an electric negative pressure suction cup or an electromagnet capable of attracting each other.

[0064] Of course, in order for the present invention to support and guide the steel strip corrugated pipe during use, the first mounting component 110 and the second mounting component 210 in the example can both be structures that can move along the steel strip corrugated pipe.

[0065] In this embodiment, the steel strip corrugated pipe is first configured as a steel strip corrugated section 01, and connecting sections 02 and insertion sections 03 that can be inserted into the connecting sections 02 are formed at both ends of the steel strip corrugated section 01, respectively. Then, a first connecting mechanism 100 and a second connecting mechanism 200 are provided. The first connecting mechanism 100 is placed inside the cavity of the corrugated pipe, and the second connecting mechanism 200 is wrapped around the outer periphery of the corrugated pipe. The first mounting component 110 in the first connecting mechanism 100 can drive the first corrugated forming component 120 to move along the length direction of the corrugated pipe inside the cavity, and the second mounting component 210 in the second connecting mechanism 200 can drive the second corrugated forming component 220 to move along the length direction of the corrugated pipe around the outer periphery. When the insertion section 03 is inserted into the connecting section 02, the first corrugated forming component 120 can cooperate with the second corrugated forming component 220. The first corrugated forming component 120 can extrude molten liquid into the inner cavity of the insertion section 03 to form a corrugated joint steel strip ring 04 connected to the corrugated steel strip section 01. The heat generated when the corrugated joint steel strip ring 04 is extruded is used to heat the insertion section 03 and the connecting section 02. This allows the present invention to convert the connecting section 02 and the insertion section 03 of the steel strip corrugated pipe into a corrugated structure during use. This also allows the present invention to prepare a steel strip corrugated pipe structure that presents a full corrugated section in the use state. This also allows the present invention to solve the technical problem in the related art that although the connection method of setting plugs or connectors at both ends of the pipe section can realize the connection function of the pipe section, the traditional connection method will prevent the connection of the pipe sections of the corrugated pipe from bending and deforming, affecting the routing of the corrugated pipe at corners and other positions.

[0066] In some exemplary embodiments, the first corrugated forming component 120 includes:

[0067] The first driving component 121 is mounted on the first mounting component 110;

[0068] The first transmission assembly 122 is mounted on the output end of the first drive member 121; and...

[0069] The first corrugated forming component 123 is hinged to the first mounting component 110 and rotates with the first transmission component 122. The first corrugated forming component 123 can heat the insertion section 03.

[0070] The first driving member 121 can drive the first transmission component 122 to rotate, thereby causing the first corrugated forming component 123 to increase in size and fit against the inner wall of the insertion section 03, and cooperate with the second corrugated forming component 220 to form a corrugated structure in the insertion section 03.

[0071] In this embodiment, by setting a first driving member 121 and installing the first driving member 121 on the first mounting member 110, and installing the first transmission component 122 on the output end of the first driving member 121, and making the first corrugated forming component 123 hinged to the first mounting member 110, and making the first corrugated forming component 123 and the first transmission component 122 rotate together, the first corrugated forming component 123 can heat the insertion section 03, and the first driving member 121 can drive the first transmission component 122 to rotate, so as to drive the first corrugated forming component 123 to enlarge and fit against the inner wall of the insertion section 03, and cooperate with the second corrugated forming component 220 to form a corrugated structure in the insertion section 03. This allows the present invention to heat the connecting section 02 and the insertion section 03 during use, thereby heating the connecting section 02 and the insertion section 03 together to form a corrugated structure, realizing the function of turning both ends of the traditional corrugated pipe into a corrugated structure during use.

[0072] It should be specifically and clearly stated that, in this embodiment, in order to facilitate the walking and telescopic functions of the first corrugated forming component 123, the example first transmission component 122 includes a support frame and a lead screw. The support frame is connected to the first driving member 121 and extends in a direction away from the first driving member 121. One end of the lead screw is connected to the output end of the first driving member 121, and the other end of the lead screw is rotatably connected to the support frame. The first corrugated forming component 123 rotates and cooperates with the lead screw, so that when the present invention is used, it can ensure that the first corrugated forming component 123 has a good guiding effect during operation.

[0073] In some exemplary embodiments, the first corrugated forming assembly 123 includes:

[0074] A first connecting bracket 124, one end of which is hinged to the first mounting component 110, and the other end of which extends away from the first driving member 121;

[0075] The first adjusting bracket 125 is rotatably mounted on the first transmission assembly 122;

[0076] A first corrugated forming component 126 is disposed around the outer periphery of the first transmission assembly 122. The first corrugated forming component 126 is simultaneously connected to both the first connecting bracket 124 and the first adjusting bracket 125. The first corrugated forming component 126 is rotatably engaged with the first connecting bracket 124.

[0077] The first heating element 127 is disposed around the outer periphery of the first corrugated forming part 126;

[0078] The first driving member 121 can drive the first transmission assembly 122 to rotate the first adjusting bracket 125, so that the first corrugated forming member 126 extends and enlarges in the direction away from the first transmission assembly 122 and fits against the inner wall of the insertion section 03, or retracts and decreases in the direction close to the first transmission assembly 122.

[0079] The first corrugated forming component 123 can extrude a corrugated joint steel strip ring 04 connected to the corrugated steel strip section 01 by extruding the inner wall of the insertion section 03, and the heat generated when the corrugated joint steel strip ring 04 is extruded is used to heat the insertion section 03 and the joint section.

[0080] In this embodiment, a first connecting bracket 124 is provided, with one end of the first connecting bracket 124 hinged to the first mounting component 110, and the other end extending away from the first driving component 121. Then, a first adjusting bracket 125 is mounted on the first transmission assembly 122, and a first corrugated forming component 126 surrounds the outer periphery of the first transmission assembly 122. The first corrugated forming component 126 is simultaneously connected to both the first connecting bracket 124 and the first adjusting bracket 125, and the first corrugated forming component 126 is connected to the first connecting bracket 124. 24. Rotate and engage, then surround the first heating element 127 around the outer periphery of the first corrugated forming element 126. The first driving element 121 can drive the first transmission assembly 122 to drive the first adjusting bracket 125 to rotate, so that the first corrugated forming element 126 extends and enlarges in the direction away from the first transmission assembly 122 and fits against the inner wall of the insertion section 03, or retracts and shrinks in the direction closer to the first transmission assembly 122. This allows the contact distance between the first corrugated forming element 126 and the connecting section 02 to be adjustable during use.

[0081] It should be specifically and clearly stated that, in this embodiment, the example first corrugated molded part 126 includes, but is not limited to, a mold capable of forming a corrugated structure under extrusion or under extrusion conditions, as is available in the prior art. The side of the example first corrugated molded part 126 near the insertion section 03 should be formed with a corrugated shape.

[0082] In some exemplary embodiments, the first corrugated forming component 126 includes a plurality of first arc-shaped connecting blocks 123a, which are arranged in annular intervals around the outer periphery of the first transmission component 122. A first arc-shaped connector 123b is provided between any two adjacent first arc-shaped connecting blocks 123a. The first arc-shaped connector 123b is slidably engaged with the two adjacent first arc-shaped connecting blocks 123a. The first arc-shaped connecting block 123a is hinged to the first adjusting bracket 125. A first groove 123c extending along the arc length direction of the first arc-shaped connecting block 123a is formed on the first arc-shaped connecting block 123a. The end of the first connecting bracket 124 away from the first mounting component 110 is slidably engaged in the first groove 123c. The first heating element 127 is installed on each of the first arc-shaped connecting blocks 123a.

[0083] In this embodiment, multiple first arc-shaped connecting blocks 123a are arranged in a ring around the outer periphery of the first transmission component 122, and any two adjacent first arc-shaped connecting blocks 123a are slidably engaged. Simultaneously, the first arc-shaped connecting blocks 123a are hinged to the first adjusting bracket 125. A first groove 123c extending along the arc length direction of the first arc-shaped connecting block 123a is formed on the first arc-shaped connecting block 123a. The end of the first connecting bracket 124 away from the first mounting component 110 is slidably engaged in the first groove 123c. This allows the invention to drive the first adjusting bracket 125 via the first transmission component 122 during use, enabling the multiple first arc-shaped connecting blocks 123a to move closer to or further away from the inner wall of the insertion section 03. This, in turn, allows the invention to adjust the size of the first corrugated forming part 126 during use.

[0084] It should be specifically and clearly stated that, in this embodiment, in order for the first corrugated forming component 126 to corrugate the insert segment 03 during the corrugation forming process, the first arc-shaped connecting block 123a and the first arc-shaped connecting component 123b disposed between any two adjacent first arc-shaped connecting blocks 123a can cooperate with the second corrugated forming component 223 to extrude the insert segment 03 and the connecting segment 02 into a corrugated structure.

[0085] It should be understood that, in order to facilitate extrusion molding, the sides of the first arc-shaped connecting block 123a and the first arc-shaped connecting piece 123b opposite to the insertion section 03 are both corrugated.

[0086] In some exemplary embodiments, there are multiple first heating elements 127, and the number of first heating elements 127 is the same as that of the first arc-shaped connecting blocks 123a and they are arranged in a one-to-one correspondence.

[0087] In this embodiment, by setting multiple first heating blocks, the present invention can perform secondary heating on the plug section 03 through the set heating blocks during use, which facilitates molding.

[0088] It should be specifically and clearly stated that the first heating block in this embodiment may be, but is not limited to, a device or equipment in the prior art that can realize the heating function. This embodiment only applies the technology and does not involve any improvement or design of the specific structure of the device itself, so it will not be elaborated here. However, it can be exemplified that the first heating block in this embodiment may be, but is not limited to, an electric heating block.

[0089] In some exemplary embodiments, the second corrugated forming component 220 includes:

[0090] Multiple second drive members 221 are circumferentially spaced and installed on the inner side of the second mounting component 210;

[0091] Multiple second transmission components 222 are mounted on the output end of the second drive component 221. The number of second transmission components and second drive components 221 are the same and they are arranged in a one-to-one correspondence.

[0092] Multiple second corrugated forming components 223 are installed at the end of the second transmission component 222 away from the second driving component 221. The number of second corrugated forming components 223 and the number of second transmission components 222 are the same and they are set one-to-one. Multiple second driving components 221 can simultaneously drive the corresponding second transmission component 222 to drive the corresponding second corrugated forming component 223 to approach and fit against the connecting section 02, so as to cooperate with the first corrugated forming component 123 to extrude the connecting section 02 and the plug-in section 03 into a corrugated structure.

[0093] In this embodiment, by setting a second driving member 221, the second driving member 221 is installed on the second mounting component 210, and the second transmission component 222 is installed on the output end of the second driving member 221. At the same time, the second corrugated forming component 223 is hinged to the second mounting component 210, and the second corrugated forming component 223 cooperates with the second transmission component 222, so that the second corrugated forming component 223 can fit against the outer wall of the connecting section 02 and cooperate with the first corrugated forming component 123 to extrude the connecting section 02 and the insertion section 03 into a corrugated structure.

[0094] It should be specifically and clearly stated that the second driving component exemplified in this embodiment can be, but is not limited to, existing devices or apparatuses capable of driving the second transmission assembly to rotate. This embodiment only applies these devices without modifying or designing their specific principles and structures; therefore, they will not be described in detail here. However, it can be exemplified that the second driving component exemplified in this embodiment can be a drive motor, and the second transmission assembly exemplified can be a gear ring.

[0095] In some exemplary embodiments, the second corrugated forming assembly 223 includes:

The second corrugated forming component 226 cooperates with the first corrugated forming assembly 123 to extrude the connecting section 02 and the insertion section 03 into a corrugated structure; and

[0097] The second heating element 229 is disposed around the outer periphery of the second corrugated forming element 226;

[0098] The second driving component 221 can drive the corresponding second transmission component 222 to move the corresponding second corrugated forming component 226 closer to or away from the outer wall of the connecting section 02.

[0099] It should be specifically and clearly stated that the second corrugated molded part 226 exemplified in this embodiment includes, but is not limited to, a mold capable of forming a corrugated structure under extrusion or under extrusion conditions, as is available in the prior art. The side of the exemplified second corrugated molded part 226 closest to the insertion section 03 should be formed with a corrugated shape.

[0100] In some exemplary embodiments, the second corrugated member 226 is arranged in an arc shape.

[0101] In this embodiment, by setting multiple second heating blocks, the present invention can perform secondary heating on the connecting section 02 through the set heating blocks during use, which facilitates molding.

[0102] It should be specifically and clearly stated that the second heating block in this embodiment may be, but is not limited to, a device or equipment in the prior art that can realize the heating function. This embodiment only applies the technology and does not involve any improvement or design of the specific device structure itself, so it will not be elaborated here. However, it can be exemplified that the second heating block in this embodiment may be, but is not limited to, an electric heating block.

[0103] In some exemplary embodiments, the second corrugated member 226 is corrugated on the side near the connecting section 02.

[0104] Based on the same technical concept, in a second aspect, the present invention proposes a steel strip corrugated pipe connection method, which applies the steel strip corrugated pipe connection device of the first aspect.

[0105] The connection method for steel strip corrugated pipes includes the following steps:

[0106] S100. Install at least two steel corrugated pipes of the first aspect at a predetermined construction position; wherein, the insertion section 03 of one steel corrugated pipe is inserted into the connection section 02 of the other steel corrugated pipe.

[0107] S200: Install the first connecting mechanism on the inner wall of any of the steel strip corrugated pipes and move it along the inner wall of the corresponding steel strip corrugated pipe to a position close to the inner wall of the connecting section of another steel strip corrugated pipe.

[0108] S300: Place the second connecting mechanism on the outer periphery of any of the steel strip corrugated pipes, and move it along the outer periphery of the corresponding steel strip corrugated pipe to the outer periphery of the insertion section near the other steel strip corrugated pipe.

[0109] S400: Align the first connecting mechanism with the second connecting mechanism;

[0110] S500, Simultaneously drive the first corrugated forming component in the first connecting mechanism and the second corrugated forming component in the second connecting mechanism to move and fit against the corresponding sidewall;

[0111] S600, control the first corrugated forming component to extrude molten liquid toward the inner wall of the insertion section and form a steel strip ring connected to the two steel strip corrugated sections.

[0112] In this embodiment, the steel strip corrugated pipe is first configured as a steel strip corrugated section 01, and connecting sections 02 and insertion sections 03 that can be inserted into the connecting sections 02 are formed at both ends of the steel strip corrugated section 01. Then, a first connecting mechanism 100 and a second connecting mechanism 200 are provided. The first connecting mechanism 100 is placed inside the cavity of the corrugated pipe, and the second connecting mechanism 200 is wrapped around the outer periphery of the corrugated pipe. The first mounting component 110 in the first connecting mechanism 100 can drive the first corrugated forming component 120 to move along the length direction of the corrugated pipe inside the cavity, and the second mounting component 210 in the second connecting mechanism 200 can drive the second corrugated forming component 220 to move along the length direction of the corrugated pipe around the outer periphery. When the insertion section 03 is inserted into the connecting section 02, the first corrugated forming component 120 can interact with the second corrugated forming component 220. The first corrugated forming component can extrude molten liquid into the inner cavity of the insertion section 03 to form a corrugated joint steel strip ring 04 connected to the corrugated steel strip section 01. The heat generated when the corrugated joint steel strip ring 04 is extruded is used to heat the insertion section 03 and the connecting section 02. This allows the present invention to convert the connecting section 02 and the insertion section 03 of the steel strip corrugated pipe into a corrugated structure during use. This also allows the present invention to produce a steel strip corrugated pipe structure with a full corrugated section in use. This also allows the present invention to solve the technical problem in the related art that although the connection method of setting plugs or joints at both ends of the pipe section can achieve the connection function of the pipe section, the traditional connection method will prevent the connection of the pipe sections from bending and deforming, affecting the routing of the corrugated pipe at corners and other positions.

[0113] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
