Description

Technical Field

[0001] This invention relates to the field of galvanized pipe technology, and in particular to a galvanized pipe connector and its installation auxiliary device. Background Technology

[0002] Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemical industry, power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, mining machinery, and greenhouse construction. Galvanized steel pipes are welded steel pipes with a hot-dip or electro-galvanized coating on their surface. Galvanizing increases the corrosion resistance of the steel pipe and extends its service life. Galvanized pipes have a wide range of applications. Besides being used as pipelines for general low-pressure fluids such as water, gas, and oil, they are also used in the petroleum industry, especially in offshore oil fields, for oil well pipes and oil pipelines; for oil heaters, condensers, and coal tar washing oil exchangers in chemical and coking equipment; and for support frames in trestle piles and mine tunnels.

[0003] Based on different usage scenarios and connection requirements, galvanized pipes have two connection methods: separate connection and fitting connection. The separate connection method is convenient for disassembly, replacement of parts, and inaccurate pipe cutting during construction. The fitting connection is more suitable for pipeline systems that require higher sealing and stability. Both of these methods usually involve butt welding of the pipe or wrapping and welding with a large-size pipe sleeve. This method is not only prone to misalignment, which reduces the strength of the galvanized pipe and makes it easy to bend during use, but also prone to weld beads, which seriously affects the construction quality.

[0004] Weld beads are metallic nodules that form on the surface of welds or galvanized pipes after welding. During the welding process of galvanized pipes, the current causes localized high-temperature melting of the metal weld joint. When the liquid metal solidifies, it flows under its own weight, forming tiny lumps. Weld beads are often accompanied by defects such as incomplete fusion and slag inclusions, which can easily lead to cracks. Weld beads alter the actual dimensions of the weld, causing stress concentration. Weld beads on the inner wall of the pipe reduce the flow cross-section, increasing resistance to medium flow. Weld beads not only affect the appearance of the weld, but also often present defects such as incomplete penetration beneath them, easily causing stress concentration. Weld beads are more likely to form inside pipes during vertical and horizontal welding, reducing the effective area inside the pipe and even causing pipe blockage.

[0005] Therefore, it is particularly important to design a galvanized pipe connector that does not require welding and its installation auxiliary device with high efficiency; in view of this, we propose a galvanized pipe connector and its installation auxiliary device. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a galvanized pipe connector and its installation auxiliary device to solve the technical problems of low efficiency and poor performance of the current galvanized pipe welding connection method.

[0011] Preferably, an eccentric block is connected to the end of the dual-axis motor away from the support column, and a collar is fitted on the eccentric block, with a connecting rod connecting the two collars.

[0012] Preferably, the propulsion mechanism includes a bearing block, a propulsion cylinder, a pushing block, a limiting rod, a fixing sleeve, and an arc-shaped groove. The bearing block is symmetrically arranged on the clamping fixture. The propulsion cylinder is located on the bearing block. The pushing block is connected to the output end of the propulsion cylinder. The limiting rod is connected to the outer wall of the pushing block. The fixing sleeve is located at the end of the bearing block away from the propulsion cylinder. The pushing block is movably inserted through the fixing sleeve. The arc-shaped groove is formed on the fixing sleeve. The limiting rod is slidably connected to the arc-shaped groove.

[0013] Preferably, the pipe pressing mechanism includes a base, a receiving plate, a hydraulic cylinder, a pipe pressing component, and an adjusting assembly. The base is positioned on the bearing plate between the two clamping fixtures. The receiving plates are symmetrically arranged at the top of the base, and the two receiving plates are arranged at an incline at the top of the base. The hydraulic cylinder is positioned on the top plate above the base. The adjusting assembly is suspended at the output end of the hydraulic cylinder above the base. The pipe pressing component is connected to the bottom end of the adjusting assembly above the two receiving plates.

[0014] Preferably, the pressure fitting includes a first fitting, a second fitting, a limiting ring, a first curved block, and a second curved block. The first fitting and the second fitting are symmetrically connected to the bottom end of the adjusting assembly. The first curved block is connected to the first fitting, and the second curved block is connected to the second fitting. Each of the first and second curved blocks has a limiting ring at the end away from the first and second fittings. The first and second curved blocks are size-matched, and the first and second curved blocks slide in conjunction with the concave ring.

[0015] Preferably, the adjusting assembly includes a connecting block, a slide rod, a through hole, a counteracting lead screw, a connecting plate, a rotary knob, a connecting rod, and a sliding groove. The connecting block is arranged at the output end of the hydraulic cylinder. The slide rod passes through the connecting block. The through hole is located on the connecting block at a position relative to the lower part of the slide rod. The counteracting lead screw is rotatably connected to the through hole. The connecting plate is symmetrically arranged at the end of the counteracting lead screw. The rotary knob is connected to the end of the connecting plate away from the counteracting lead screw. One end of the connecting rod is connected to the bottom end of the connecting plate, and the other end of the connecting rod is connected to the pressure pipe fitting. The sliding groove is located at the bottom end of the connecting block, and the pressure pipe fitting is movably connected to the sliding groove.

[0016] A method using the above-described installation auxiliary device includes the following steps:

[0017] S1, tube delivery operation;

[0018] Firstly, support frames are symmetrically arranged on the bearing plate, and several limiting blocks are evenly spaced at the top of the support frames. Bearing rods are also installed on the support frames, and support columns are installed between the two support frames. A dual-axis motor is installed on the support column, and a rocker arm is connected to one end of the dual-axis motor. The dual-axis motor drives the rocker arm to rotate, and the rocker arm drives the transfer frame and the pipe support block to rotate, so that the galvanized pipe moves forward through the transfer frame and the pipe support block. An eccentric block is connected to the end of the dual-axis motor away from the support column, and a collar is fitted on the eccentric block. A connecting rod is connected between the collars of the two dual-axis motors so that the two eccentric blocks, the dual-axis motors, the rocker arm, the transfer frame and the pipe support block rotate synchronously, and finally the pipe is transferred to the clamping fixture, where it is clamped.

[0019] S2, Clamping and positioning operation;

[0020] Because there are symmetrically arranged bearing blocks on the clamping fixture, and a pusher cylinder is set on the bearing block, the pusher cylinder drives the pusher block to pass through the fixed sleeve. Because there is an arc rail groove on the fixed sleeve, and a limit rod is set on the outer wall of the pusher block, the limit rod slides in the arc rail groove, causing the pusher block to rotate, which drives the galvanized pipe to rotate and advance.

[0021] S3, Adjustment operation;

[0022] S301. If it is necessary to connect the galvanized pipes separately, manually turn the knob to drive the opposing screw to rotate on the through hole. The rotation of the opposing screw causes the matching connecting plate to move on the opposing screw. Through the connecting rod, the first pipe and the second pipe slide opposite to each other on the slide groove, so that the first pipe and the second pipe are separated, and the first pipe and the second pipe press down on the raised part of the concave ring.

[0023] S302. If it is necessary to fit and connect the galvanized pipe, manually turn the knob to drive the opposing screw to rotate on the through hole. The rotation of the opposing screw causes the matching connecting plate to move on the opposing screw. Through the connecting rod, the first pipe and the second pipe slide opposite to each other on the slide groove, so that the first pipe and the second pipe merge, and the first pipe and the second pipe are adapted to the shape of the body, the pipe groove and the concave ring.

[0024] S4, Pressing operation;

[0025] Because a base is set on the bearing plate between two clamping fixtures, and two receiving plates are set on the base, the hydraulic cylinder is set on the top plate above the base, and the adjustment component is suspended at the output end of the hydraulic cylinder. The hydraulic cylinder drives the adjustment component and the pressing pipe to press down, so that the galvanized pipe and the pipe groove are pressed tightly until the honeycomb pressing cavity produces a certain deformation, making the connection tighter.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention improves upon existing galvanized pipe connection methods by symmetrically creating pipe grooves on the connector body and placing a concave ring between two grooves. When a cable is threaded through the galvanized pipe, the smooth, curved inner wall of the concave ring facilitates connection and ensures a smooth internal connection, improving construction efficiency and reducing cable damage during threading. Curved grooves are created on the inner wall of the connector, with rubber strips added to enhance sealing and waterproofing. Furthermore, several honeycomb pressure cavities are arranged in a ring inside the connector body to ensure a tight seal when the connector and galvanized pipe are pressed together, improving connection effectiveness and preventing deformation of the galvanized pipe during the pressing process. This invention optimizes the use of the galvanized pipe connector and its installation auxiliary devices, improving connection efficiency and facilitating the advancement of galvanized pipe technology.

[0028] 2. This invention improves upon existing galvanized pipe connection methods by installing a pipe-passing mechanism on a workbench, a clamping fixture next to the pipe-passing mechanism, a pushing mechanism on the clamping fixture, and a pressing mechanism at the middle of the pushing mechanism. This allows the galvanized pipe to be passed to the clamping fixture for clamping and positioning via the pipe-passing mechanism, then inserted into the galvanized pipe connector via the pushing mechanism, and finally pressed together with the connector via the pressing mechanism. Compared to manual welding, this installation-assisted connection method avoids weld beads and misaligned threads, thus improving construction quality and further enhancing installation efficiency.

[0029] 3. This invention symmetrically arranges support frames on a bearing plate, with several limiting blocks evenly spaced at the top of the support frames. The support frames also have bearing rods, and a support column is positioned between two support frames. A dual-axis motor is mounted on the support column, with a rocker arm connected to one end. The dual-axis motor drives the rocker arm to rotate, which in turn drives the transfer frame and the pipe-bearing block to rotate. This allows the galvanized pipe to move forward through the transfer frame and the pipe-bearing block, ultimately being transferred to the clamping fixture for clamping, positioning, and installation with the galvanized pipe connector. This saves labor and improves auxiliary installation efficiency.

[0030] 4. This invention symmetrically arranges bearing blocks on the clamping fixture, and sets a propulsion cylinder on the bearing block. The propulsion cylinder drives the push block to pass through the fixed sleeve. Since the fixed sleeve has an arc groove, and the outer wall of the push block is provided with a limit rod, the limit rod slides in the arc groove, causing the push block to rotate, which drives the galvanized pipe to rotate and advance. This makes the connection between the galvanized pipe and the galvanized pipe connector faster and more efficient, and also facilitates the later arrangement of rubber strips between the galvanized pipe and the galvanized pipe connector to improve the sealing performance of the connection.

[0031] 5. This invention features a connecting block at the output end of a hydraulic cylinder, a sliding rod passing through the connecting block, a through hole at the bottom of the sliding rod, and a movably connected opposing lead screw in the through hole. A connecting plate is mounted on the opposing lead screw, and a rotating knob is installed on the connecting plate. A connecting rod is connected to the bottom of the connecting plate, and the other end of the connecting rod is connected to a first and a second pipe fitting. A sliding groove is formed at the bottom of the connecting block, and the first and second pipe fittings are slidably connected to the sliding groove. Manually rotating the knob causes the opposing lead screw to rotate in the through hole. The rotation of the opposing lead screw causes the matching connecting plate to move on the opposing lead screw. The connecting rod drives the first and second pipe fittings to slide opposite each other in the sliding groove, thus enabling both separate and fitted connections of galvanized pipes. This improves installation efficiency and optimizes usage. Attached Figure Description

[0055] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0056] Example 1: A galvanized pipe connector, see [link / reference] Figures 1 to 2The connector body 1 includes a housing 2, a tube groove 3, a concave ring 4, a honeycomb pressure cavity 5, and a curved groove 11. The tube grooves 3 are symmetrically opened on the housing 2. The concave ring 4 is located on the housing 2 between two tube grooves 3. The honeycomb pressure cavity 5 is opened in a ring at equal intervals inside the housing 2. The curved groove 11 is symmetrically opened on the inner wall of the tube groove 3. The housing 2, tube groove 3, concave ring 4, honeycomb pressure cavity 5, and curved groove 11 are all integrally formed structures. The inner wall of the concave ring 4 has an arc-shaped structure. This invention improves upon existing galvanized pipe connection methods by symmetrically creating pipe grooves 3 on the connector body 1's housing 2 and placing concave rings 4 between two grooves 3. When a cable is threaded through the galvanized pipe, the smooth, curved inner wall of the concave rings 4 facilitates connection and ensures a smooth internal surface, improving construction efficiency and reducing cable damage during threading. Curved grooves 11 are created on the inner wall of the connector body 1, with rubber strips on these grooves to enhance sealing and waterproofing. Furthermore, several honeycomb pressure cavities 5 are arranged in a ring inside the housing 2 to ensure a tight seal between the connector body 1 and the galvanized pipe during compression, improving connection effectiveness and preventing deformation of the galvanized pipe. This invention, through the cooperation of the connector body 1 and installation auxiliary devices, optimizes usage, improves connection efficiency, and facilitates the advancement of galvanized pipe technology.

[0057] Example 2: An installation auxiliary device, such as Figures 3 to 15 As shown, the invention includes a crimping mechanism 10 for carrying the galvanized pipe connector as described in claim 1. The crimping mechanism 10 is mounted on a workbench 6, which is equipped with a pipe delivery mechanism 7. A clamping fixture 8 is symmetrically positioned on the workbench 6 relative to the pipe delivery mechanism 7, and a pushing mechanism 9 is mounted on the clamping fixture 8. This invention improves upon existing galvanized pipe connection methods by providing a pipe delivery mechanism 7 on the workbench 6, a clamping fixture 8 positioned next to the pipe delivery mechanism 7 on the workbench 6, a pushing mechanism 9 mounted on the clamping fixture 8, and a crimping mechanism 10 positioned at the middle of the pushing mechanism 9. This allows the galvanized pipe to be delivered by the pipe delivery mechanism 7 to the clamping fixture 8 for clamping and positioning. The pushing mechanism 9 then inserts the galvanized pipe into the connector body 1. Finally, the crimping mechanism 10 presses the galvanized pipe and connector body 1 together. Compared to manual welding, this installation-assisted connection method avoids weld beads and misaligned threads, thus improving construction quality and further enhancing installation efficiency.

[0058] Furthermore, the workbench 6 includes a base frame 601, a support plate 602, a vertical frame 603, a top frame 604, and a top plate 605. The support plate 602 is mounted on the base frame 601, the vertical frame 603 is mounted on the base frame 601 relative to the support plate 602, the top frame 604 is mounted on the top of the vertical frame 603, and the top plate 605 is mounted on the top frame 604. The pipe-passing mechanism 7 is mounted at one end of the support plate 602, the clamping fixture 8 is mounted at the other end of the support plate 602, the bottom end of the pipe-pressing mechanism 10 is mounted on the support plate 602 relative to the position below the clamping fixture 8, and the top end of the pipe-pressing mechanism 10 is mounted on the top plate 605 relative to the position above the clamping fixture 8. The present invention provides a support plate 602 on a base frame 601, an upright frame 603 on the base frame 601 relative to the support plate 602, a top frame 604 on the top of the upright frame 603, and a top plate 605 on the top frame 604. A pipe delivery mechanism 7, a clamping fixture 8, and a pushing mechanism 9 are sequentially arranged on the support plate 602. The bottom end of the pipe pressing mechanism 10 is located on the support plate 602 below the clamping fixture 8, and the top end of the pipe pressing mechanism 10 is located on the top plate 605 above the clamping fixture 8. This arrangement of the installation auxiliary device mechanism improves its installation efficiency.

[0059] It is worth noting that the pipe delivery mechanism 7 includes a support frame 701, a limiting block 702, a bearing rod 703, a support column 704, a rocker arm 705, a dual-axis motor 706, a transfer frame 707, and a pipe receiving block 708. The support frame 701 is symmetrically arranged on the bearing plate 602. Several limiting blocks 702 are arranged at equal intervals at the top of the support frame 701. The bearing rod 703 is connected to the end of the support frame 701 away from the clamping fixture 8. The support column 704 is located on the bearing plate 602 between two support frames 701. The dual-axis motor 706 is arranged on one side of the top of the support column 704. The rocker arm 705 is arranged on the other side of the top of the support column 704 and connected to the output end of the dual-axis motor 706. The transfer frame 707 is connected to the end of the rocker arm 705 away from the support column 704. Several pipe receiving blocks 708 are connected at equal intervals to the top of the transfer frame 707. This invention symmetrically arranges support frames 701 on a bearing plate 602, with several limiting blocks 702 evenly spaced at the top of the support frames 701. Support rods 703 are also provided on the support frames 701, and support columns 704 are provided between two support frames 701. A dual-axis motor 706 is installed on the support column 704, with one end of the dual-axis motor 706 connected to a rocker arm 705. The dual-axis motor 706 drives the rocker arm 705 to rotate, which in turn drives the transfer frame 707 and the pipe support block 708 to rotate. This allows the galvanized pipe to move forward through the transfer frame 707 and the pipe support block 708, ultimately being transferred to the clamping fixture 8 for clamping, positioning, and installation connection with the connector body 1. This saves labor and improves auxiliary installation efficiency.

[0060] It is worth noting that an eccentric block 7061 is connected to the end of the dual-axis motor 706 away from the support column 704. A collar 7062 is fitted on the eccentric block 7061, and a connecting rod 7063 connects the two collars 7062. This invention, by connecting the eccentric block 7061 to the end of the dual-axis motor 706 away from the support column 704, fitting the collar 7062 on the eccentric block 7061, and connecting the connecting rod 7063 between the collars 7062 of the two dual-axis motors 706, enables the two eccentric blocks 7061, the dual-axis motor 706, the rocker arm 705, the transfer frame 707, and the pipe receiving block 708 to rotate synchronously, preventing the pipe delivery mechanism 7 from malfunctioning due to asynchronous rotation.

[0061] It is worth mentioning that the propulsion mechanism 9 includes a bearing block 901, a propulsion cylinder 902, a push block 903, a limit rod 904, a fixed sleeve 905, and an arc track groove 906. The bearing block 901 is symmetrically arranged on the clamping fixture 8. The propulsion cylinder 902 is arranged on the bearing block 901. The push block 903 is connected to the output end of the propulsion cylinder 902. The limit rod 904 is connected to the outer wall of the push block 903. The fixed sleeve 905 is arranged at the end of the bearing block 901 away from the propulsion cylinder 902. The push block 903 is movably inserted through the fixed sleeve 905. The arc track groove 906 is opened on the fixed sleeve 905. The limit rod 904 is slidably connected to the arc track groove 906. This invention symmetrically arranges bearing blocks 901 on the clamping fixture 8, and sets a pushing cylinder 902 on the bearing block 901. The pushing cylinder 902 drives the pushing block 903 to pass through the fixed sleeve 905. Since the fixed sleeve 905 has an arc track groove 906, and the outer wall of the pushing block 903 is provided with a limit rod 904, the limit rod 904 slides inside the arc track groove 906, causing the pushing block 903 to rotate, driving the galvanized pipe to rotate and advance. This makes the connection between the galvanized pipe and the connector body 1 faster and more efficient, and also facilitates the later arrangement of a rubber strip between the galvanized pipe and the connector body 1 to improve the sealing performance of the connection.

[0062] It is worth emphasizing that the pipe pressing mechanism 10 includes a base 101, a receiving plate 102, a hydraulic cylinder 103, a pipe pressing component 104, and an adjusting assembly 105. The base 101 is located on the bearing plate 602 between the two clamping fixtures 8. The receiving plates 102 are symmetrically arranged at the top of the base 101, and the two receiving plates 102 are arranged at an incline at the top of the base 101. The hydraulic cylinder 103 is located on the top plate 605 above the base 101. The adjusting assembly 105 is suspended at the output end of the hydraulic cylinder 103 above the base 101. The pipe pressing component 104 is connected to the bottom end of the adjusting assembly 105 above the two receiving plates 102. The present invention provides a base 101 on the support plate 602 between two clamping fixtures 8, and two receiving plates 102 on the base 101. A hydraulic cylinder 103 is located on the top plate 605 above the base 101. An adjustment component 105 is suspended at the output end of the hydraulic cylinder 103. The hydraulic cylinder 103 drives the adjustment component 105 and the pressing pipe component 104 to press down, so that the galvanized pipe and the connector body 1 are pressed tightly together, which helps to improve the connection and installation efficiency.

[0063] It is worth noting that the pressure fitting 104 includes a first fitting 1041, a second fitting 1042, a limiting ring 1043, a first curved block 1044, and a second curved block 1045. The first fitting 1041 and the second fitting 1042 are symmetrically connected to the bottom of the adjusting assembly 105. The first curved block 1044 is connected to the first fitting 1041, and the second curved block 1045 is connected to the second fitting 1042. The first curved block 1044 and the second curved block 1045 are each provided with a limiting ring 1043 at the end away from the first fitting 1041 and the second fitting 1042. The first curved block 1044 and the second curved block 1045 are size-matched, and the first curved block 1044 and the second curved block 1045 slide and engage with the concave ring 4. This invention provides a first pipe fitting 1041 and a second pipe fitting 1042 at the bottom of the adjusting component 105. The first pipe fitting 1041 is connected to a plurality of first curved blocks 1044 and a limiting ring 1043, and the second pipe fitting 1042 is connected to a plurality of second curved blocks 1045 and a limiting ring 1043. The cooperation between the first curved blocks 1044 and the second curved blocks 1045 allows them to fit the shape of the concave ring 4 and be pressed together. This allows for quick connection of galvanized pipes without welding, improving installation efficiency.

Through the connecting rod 1057, the first pipe fitting 1041 and the second pipe fitting 1042 are driven to slide opposite each other on the slide groove 1058, so that the first pipe fitting 1041 and the second pipe fitting 1042 are separated, and the first pipe fitting 1041 and the second pipe fitting 1042 press down on the raised part of the lower body 2 and the concave ring 4.

[0072] S302. If it is necessary to fit and connect the galvanized pipe, manually turn the knob 1056 to drive the opposing screw 1054 to rotate on the through hole 1053. The rotation of the opposing screw 1054 causes the matching connecting plate 1055 to move on the opposing screw 1054. Through the connecting rod 1057, the first pipe fitting 1041 and the second pipe fitting 1042 are driven to slide opposite each other on the slide groove 1058, so that the first pipe fitting 1041 and the second pipe fitting 1042 are combined, and the first pipe fitting 1041 and the second pipe fitting 1042 are adapted to the shape of the device body 2, the pipe groove 3 and the concave ring 4.

[0073] S4, Pressing operation;

[0074] Since a base 101 is set on the bearing plate 602 at a position between the two clamping fixtures 8, and two receiving plates 102 are set on the base 101, the hydraulic cylinder 103 is set on the top plate 605 at a position above the base 101, the adjusting component 105 is suspended at the output end of the hydraulic cylinder 103, and the hydraulic cylinder 103 drives the adjusting component 105 and the pressing pipe component 104 to press down so that the galvanized pipe and the pipe groove 3 are pressed tightly until the honeycomb pressing cavity 5 produces a certain deformation to make the connection tighter.
