Description

Technical Field

[0001] The invention relates to the technical field of metal pipe processing, and in particular to a repairing device for a deformed metal pipe. Background Art

[0002] In modern industry and daily life, metal pipes are widely used in various fields. However, in the production, transportation, installation and use of metal pipes, they are often deformed due to various reasons. This deformation may affect the performance, function and subsequent use of metal pipes. There are many reasons for the deformation of metal pipes. In the production process, local deformation may be caused by imperfect or inaccurate manufacturing process. Collisions, extrusions and other situations during transportation can also easily cause metal pipes to deform. In the installation process, improper operation or external force can also cause deformation. In addition, long-term use, environmental factors and continuous external stress may cause metal pipes to gradually deform. After the metal pipe is deformed, if it is not corrected in time, it will bring a series of adverse consequences. For example, in the fluid conveying system, the deformed metal pipe may cause the fluid flow to be blocked, affect the stability of flow and pressure, and even cause safety hazards such as leakage. In terms of structural support, the deformed metal pipe will reduce its bearing capacity and stability, posing a threat to the safety of the overall structure.

[0003] In order to solve the problem of metal tube deformation, metal tube deformation correction technology came into being. Most of the common metal correction machines on the market correct the surface of the metal tube by cyclic extrusion on the outside of the metal tube. However, for metal tubes with severe deformation and severe bending on the surface, as shown in the attached manual, Fig.10 In the situation shown, when the metal tube has been flattened into a C-shaped structure, if it is squeezed from the outside of the metal tube at this time, it will only make the dent in the middle of the metal tube more serious.

DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes a device for repairing a deformed metal pipe according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, the repair device for a deformed metal pipe provided in an embodiment of the present invention comprises an extrusion repair mechanism 1, a driving mechanism 2 and a walking mechanism 3, wherein the extrusion repair mechanism 1 is used to rotate and extrude the extruded and deformed metal pipe in all directions along its inner wall to repair the extrusion repair, and the extrusion repair mechanism 1 comprises a first supporting push rod 12, an extrusion wheel 11 and a rotating head 13, wherein the first supporting push rod 12 is telescopically arranged on the rotating head 13, the extrusion wheel 11 is arranged at the end of the push-pull shaft 122 of the first supporting push rod 12, and the rotating head 13 is rotatably arranged on the driving mechanism 2, and the driving mechanism 2 is used to drive the rotating head 13 to rotate.

[0023] The walking mechanism 3 is used to drive the extrusion repair mechanism 1 to move along the inner wall of the metal tube. The walking mechanism 3 includes a second support push rod 33 and a walking wheel 31, wherein the second support push rod 33 is telescopically arranged on the driving mechanism 2, and the walking wheel 31 is arranged at the end of the push-pull shaft 122 of the second support push rod 33.

[0024] Specifically, when repairing a deformed metal pipe, the device is first sent into the interior of the metal pipe from one end of the metal pipe, and then the extrusion wheel 11 is driven to support the inner wall of the metal pipe by extending the first support rod, and the walking wheel 31 is driven to support the inner wall of the metal pipe by extending the second support rod. After all the extrusion wheels 11 and the walking wheels 31 are supported on the inner wall of the metal pipe, the driving mechanism 2 drives the rotating head 13 to rotate, and the rotating head 13 drives the extrusion wheel 11 to rotate along the inner wall of the metal pipe, so that the deformed metal pipe wall is gradually restored to a circumferential wall. While the extrusion wheel 11 rotates, the walking wheel 31 walks on the inner wall of the metal pipe, driving the extrusion wheel 11 to continuously penetrate into the interior of the metal pipe, so that the deformed metal pipe is gradually restored.

[0025] In one embodiment of the present invention, Figure 3 and Figure 6 As shown, the driving mechanism 2 includes a base 27, a rotor shaft 23, blades 24 and a rotor slot 28, wherein the rotor slot 28 is opened inside the base 27, a stator ring 283 is arranged on the inner wall of the rotor slot 28, the rotor shaft 23 is rotatably arranged inside the rotor slot 28, the rotor shaft 23 is eccentrically arranged relative to the central axis of the rotor slot 28, the blades 24 are elastically and telescopically arranged on the circumferential wall of the rotor shaft 23, a blade movable groove 284 is opened on the circumferential wall of the rotor shaft 23, a compression spring is arranged at the bottom of the blade movable groove 284, one end of the rotor shaft 23 is dynamically connected to the rotating head 13, an oil inlet 281 is opened at the top of the rotor slot 28, and an oil outlet 282 is opened at the bottom of the rotor slot 28.

[0026] Specifically, the driving mechanism 2 is driven by hydraulic oil. When the hydraulic oil enters the rotor slot 28 from the oil inlet 281, Figure 6 As shown, the rotor slot 28 is separated into several slots by the blades 24, and the slot space is smaller as it is closer to the oil inlet 281, and larger as it is closer to the oil outlet 282. Therefore, the hydraulic oil at the oil inlet 281 gradually pushes the blades 24 toward the oil outlet 282 for pressure release, driving the blades 24 to rotate, and then driving the rotor shaft 23 to rotate. The rotor shaft 23 rotates to drive the rotating head 13 to rotate.

[0027] In one embodiment of the present invention, Figure 3As shown, a first oil chamber 25 is opened on one side of the base 27 close to the rotating head 13, a reduction gear 22 is arranged on the inner side of the rotating head 13, an output shaft gear 21 is arranged at one end of the rotor shaft 23, and the output shaft gear 21 and the reduction gear 22 are both arranged inside the first oil chamber 25, and the output shaft gear 21 and the reduction gear 22 are meshed with each other.

[0028] A sealed bearing 15 is arranged between the rotating head 13 and the first oil chamber 25, and a hydraulic channel 14 is opened inside the rotating head 13. One end of the hydraulic channel 14 is connected to the oil cylinder 123 of the first supporting push rod 12, and the other end of the hydraulic channel 14 is connected to the first oil chamber 25 through an oil port 141 opened on the reduction gear 22.

[0029] Specifically, the rotor shaft 23 is driven by the hydraulic oil to rotate, and the rotor shaft 23 drives the output shaft gear 21 to rotate. The output shaft gear 21 and the reduction gear 22 are meshed with each other to drive the rotating head 13 to rotate, and then drive the extrusion wheel 11 to rotate. In this process, the hydraulic oil passing through the rotor groove 28 flows out to the first oil chamber 25 through the oil outlet 282. At this time, the hydraulic oil enters the first support push rod 12 through the hydraulic flow channel 14. The pressure of the hydraulic oil pushes the first support push rod 12 to extend, driving the extrusion wheel 11 to tightly support the inner wall of the metal pipe, and supports and restores the deformed metal pipe.

[0030] And because the output shaft gear 21 and the reduction gear 22 are both arranged inside the first oil chamber 25, the output shaft gear 21 and the reduction gear 22 are both immersed in the hydraulic oil, and the hydraulic oil lubricates the output shaft gear 21 and the reduction gear 22 to reduce gear wear.

[0031] In one embodiment of the present invention, Figure 3 As shown, a second oil chamber 26 is provided at the bottom of the base 27, an oil outlet 282 of the rotor slot 28 is connected to the first oil chamber 25, the first oil chamber 25 is connected to the second oil chamber 26, and a filter 261 is provided inside the second oil chamber 26. The second oil chamber 26 is connected to the internal oil cylinder 123 of the second support push rod 33.

[0032] Specifically, the hydraulic oil enters the second oil chamber 26 from the first oil chamber 25, and then enters the second support push rod 33, driving the second support push rod 33 to extend. The second support push rod 33 drives the walking wheel 31 to tightly support the inner wall of the metal tube. The walking drive motor 32 built into the walking wheel 31 drives the walking wheel 31 to rotate, thereby driving the entire device to move along the inner wall of the metal tube.

[0033] In one embodiment of the present invention, Figure 3 As shown, an angle rotation adjustment component is provided between the first support push rod 12 and the rotating head 13 , the angle rotation component is an angle rotation motor, and the middle part of the rim of the extrusion wheel 11 is raised.

[0034] Specifically, by setting an angle rotation adjustment component between the first supporting push rod 12 and the rotating head 13, when the walking wheel 31 drives the extrusion wheel 11 to walk on the inner wall of the metal tube, the extrusion wheel 11 makes a spiral motion on the inner wall of the metal tube, gradually supporting and correcting the inner wall of the metal tube, and because the middle part of the wheel rim of the extrusion wheel 11 is raised, the sliding friction between the extrusion wheel 11 and the inner wall of the metal tube is reduced.

[0035] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, the rim portion of the traveling wheel 31 is provided with a magnetic wheel, and the surface of the magnetic wheel is provided with anti-slip textures.

[0036] Specifically, the magnetic running wheel 31 makes it fit more closely with the inner wall of the metal tube, and the downward pressure between the booster running wheel 31 and the inner wall of the metal tube makes the running wheel 31 obtain greater friction. The running wheel 31 cooperates with the anti-slip texture set on the rim to prevent the running wheel 31 from slipping during movement.

[0037] In one embodiment of the present invention, Figure 1 and Fig. 9 As shown, a hydraulic drive mechanism 4 is provided on one side of the base 27, and the hydraulic drive mechanism 4 includes a boost pump 45 and a transmission pump 44, wherein the output end of the boost pump 45 is connected to the input end of the transmission pump 44, and the output end of the transmission pump 44 is provided with an oil inlet pipe 42, the oil inlet pipe 42 is connected to the oil inlet port 281, and the oil outlet port 282 is provided with an oil outlet pipe 43, the oil outlet pipe 43 and the oil inlet pipe 42 are bound by the same pipe sleeve 41, and the oil outlet end of the oil outlet pipe 43 is connected to the input end of the boost pump 45.

[0038] Specifically, in the process of supplying hydraulic oil to the device, the hydraulic oil is sucked in and pressurized by the booster pump 45, providing a certain downward force to the first support push rod 12 and the second support push rod 33, which is used for the extrusion wheel 11 and the walking wheel 31 to support the inner wall of the metal pipe. The pressurized hydraulic oil is sent into the interior of the device through the transmission pump 44. The transmission pump 44 makes the hydraulic oil have a certain flow rate, which is used to adjust the rotation speed of the extrusion wheel 11.

[0039] In one embodiment of the present invention, Figure 4 As shown, the first support push rod 12 and the second support push rod 33 are both piston push rods, and a tension spring 121 is provided between the bottom of the oil cylinder 123 of the first support push rod 12 and the second support push rod 33 and the push-pull shaft 122, and the tension spring 121 plays a role of reset. The first support push rod 12 and the second support push rod 33 are provided with a lifting force by the pressure of the hydraulic oil, so as to support and correct the inner wall of the metal pipe.

[0040] In order to clearly explain the above embodiments, refer to Figure 1-Figure 10 The specific working principle of the repairing device for deformed metal pipe of the present invention is as follows: When the staff needs to repair the deformed metal pipe, they first send the device into the metal pipe from one end, and then use the booster pump 45 to suck in the external hydraulic oil and boost it. The hydraulic oil enters the first support push rod 12, the rotor slot 28 and the second support push rod 33 in turn through the oil inlet pipe 42. The boosted hydraulic oil provides a certain downward force for the first support push rod 12 and the second support push rod 33 to achieve the support of the extrusion wheel 11 and the travel wheel 31 on the inner wall of the metal pipe. At the same time, the boosted hydraulic oil is sent into the device through the transmission pump 44. The transmission pump 44 makes the hydraulic oil have a certain flow rate, which is used to adjust the rotation speed of the blades 24 in the rotor slot 28, and then adjust the rotation speed of the extrusion wheel 11 along the inner wall of the metal pipe.

[0041] The extrusion wheel 11 exerts a certain downward pressure on the metal tube and continuously rotates along the inner wall of the metal tube to support the sunken and deformed inner wall of the metal tube so that it can be restored to its original circumferential wall. While the extrusion wheel 11 rotates, the walking wheel 31 is driven by the built-in motor to walk on the inner wall of the metal tube. In this way, the extrusion wheel 11 spirals forward along the inner wall of the metal tube, driving the extrusion wheel 11 to continuously penetrate into the interior of the metal tube, so that the deformed metal tube is gradually restored.

[0042] In summary, the repairing device for a deformed metal tube in an embodiment of the present invention supports and bears force from the inner wall of the metal tube outward through the extrusion wheel 11, and the extrusion wheel 11 is supported by the first support push rod 12, so that the extrusion wheel 11 is tightly pressed against the inner wall of the metal tube, and the deformed part of the metal tube is supported and restored from the inside to the outside through the first support push rod 12, and the extrusion wheel 11 is rotated and extruded to restore the metal tube wall to a circumferential wall, thereby effectively correcting the severely dented and deformed metal tube.

[0043] The driving mechanism 2 is driven by hydraulic oil. The hydraulic oil enters the rotor groove 28 from the oil inlet 281, which can drive the rotor shaft 23 to rotate. The rotor shaft 23 pushed by the hydraulic oil can drive the rotating head 13 to rotate. At the same time, the rotor shaft 23 drives the output shaft gear 21 to rotate. The output shaft gear 21 and the reduction gear 22 are engaged with each other to drive the rotating head 13 to rotate, thereby rotating the extrusion wheel 11.

[0044] Since the output shaft gear 21 and the reduction gear 22 are both disposed inside the first oil chamber 25 , the output shaft gear 21 and the reduction gear 22 are both immersed in the hydraulic oil, which can lubricate the output shaft gear 21 and the reduction gear 22 to reduce gear wear.

[0045] In addition, the magnetic running wheel 31 can fit more closely with the inner wall of the metal tube, increasing the downward pressure between the running wheel 31 and the inner wall of the metal tube, thereby making the running wheel 31 obtain greater friction. The running wheel 31 cooperates with the anti-slip texture set on its rim to prevent the running wheel 31 from slipping during movement.

[0046] The hydraulic oil flows from the first oil chamber 25 into the second oil chamber 26, and then into the second support push rod 33, thereby driving the second support push rod 33 to extend. The second support push rod 33 can drive the walking wheel 31 to tightly support the inner wall of the metal tube. The walking wheel 31 is driven to rotate by the built-in walking drive motor 32, thereby causing the entire device to move along the inner wall of the metal tube, and at the same time, it also drives the extrusion wheel 11 to tightly support the inner wall of the metal tube to support and restore the deformed metal tube.

[0047] In the process of supplying hydraulic oil to the device, the hydraulic oil is sucked in and pressurized by the booster pump 45, providing a certain downward force for the first support push rod 12 and the second support push rod 33, so as to support the inner wall of the metal tube by the extrusion wheel 11 and the walking wheel 31. The pressurized hydraulic oil is sent into the interior of the device through the transmission pump 44. The transmission pump 44 makes the hydraulic oil have a certain flow rate, which is used to adjust the rotation speed of the extrusion wheel 11.

[0048] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
