[0038] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0039] According to an embodiment of the present application, a pipe orifice non - repair spraying clamping mechanism is provided. The pipe orifice non - repair spraying clamping mechanism is used to clamp a pipe 1. The pipe orifice non - repair spraying clamping mechanism includes a supporting device 2 and a supporting device 3, and the supporting device 3 is connected to the supporting device 2; the supporting device 3 includes an abutting part 32, the abutting part 32 is arranged on the supporting device 2, and the abutting part 32 is connected to the end of the pipe 1; in a state where the supporting device 3 is connected to the pipe 1, the abutting part 32 is embedded in the pipe 1.

[0040] As Figure 1 and Figure 2 shown, the spraying clamping mechanism is used to clamp the pipeline 1 and drive the pipeline 1 to move for spraying operation on the pipeline 1.

[0041] The support device 2 can drive the supporting device 3 to move. In the state where the supporting device 3 is not connected to the pipeline 1, the support device 2 can be used to adjust the position of the supporting device 3 so that the supporting device 3 corresponds to the port of the pipeline 1, facilitating the connection between the supporting device 3 and the pipeline 1 port. In the state where the supporting device 3 is connected to the pipeline 1, the support device 2 can drive the supporting device 3 and the pipeline 1 to move, facilitating operations such as pipeline 1 transportation and spraying operation on the pipeline 1.

[0042] The supporting device 3 includes an abutting portion 32. In the state where the supporting device 3 is connected to the pipeline 1, the abutting portion 32 is embedded in the pipeline 1, and the connection between the supporting device 3 and the pipeline 1 is achieved by means of internal support.

[0043] As Figure 3 shown, the abutting portion 32 is arranged on the support device 2. In the state where the supporting device 3 is not connected to the pipeline 1, the support device 2 can be used to adjust the position of the abutting portion 32 so that the abutting portion 32 corresponds to the port of the pipeline 1, facilitating the connection between the abutting portion 32 and the pipeline 1 port. In the state where the supporting device 3 is connected to the pipeline 1, the abutting portion 32 is embedded in the port of the pipeline 1, and the support device 2 can drive the abutting portion 32 and the pipeline 1 to move, so that the pipeline 1 can correspond to the nozzle of the spraying device, with high adaptability.

[0044] In the embodiment of the present application, the abutting portion 32 is embedded in the pipeline 1, and the connection between the supporting portion 3 and the pipeline 1 can be achieved by means of rigid support, flexible support, threaded connection, etc.

[0045] In the embodiment of the present application, by embedding the abutting portion 32 of the supporting device 3 into the pipeline 1 so that the abutting portion 32 abuts against the inner wall of the pipeline 1, the connection between the supporting device 3 and the pipeline 1 is realized by means of internal support. By connecting the supporting device 3 to the pipeline 1 through the abutting portion 32 of the supporting device 3, it can effectively prevent the supporting device 3 from blocking the outside of the pipeline 1, resulting in an unsprayed area during the spraying process of the pipeline 1, and the need for secondary spraying of the pipeline 1 to repair the unsprayed area.

[0046] In one example, in the state where the supporting device 3 is connected to the pipeline 1, the abutting portion 32 has a force that presses against the inner wall of the pipeline 1 from the axis of the pipeline 1.

[0047] As Figure 4As shown, the supporting device 3 and the pipeline 1 can be connected in a flexible support manner. For example, the abutting portion 32 can elastically deform along the radial direction of the pipeline 1. It can also be connected in a rigid support manner. For example, a hydraulic drive method is used to make the abutting portion abut against the inner wall of the pipeline 1 to realize the connection between the supporting device 3 and the pipeline 1.

[0048] Of course, in the embodiments of the present application, the connection between the supporting device and the pipeline is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the abutting portion 32 can also be embedded in the pipeline 1 by interference fit, threaded connection, etc. to realize the connection between the supporting device 3 and the pipeline 1.

[0049] In the state where the abutting portion 32 is embedded in the pipeline 1, the abutting portion 32 can not only abut against the inner wall of the pipeline 1, but also has a force that pushes against the inner wall of the pipeline 1 from the abutting portion 32. This can not only further improve the connection stability between the supporting device 3 and the pipeline 1, but also be beneficial for the abutting portion 32 to still abut against the inner wall of the pipeline 1 when the pipeline 1 is in states such as thermal expansion and cooling contraction, avoiding the situation where the connection between the supporting device 3 and the pipeline 1 becomes unstable due to reasons such as thermal expansion and contraction.

[0050] In an example, in the state where the supporting device 3 is connected to the pipeline 1, the abutting portion 32 elastically deforms along the radial direction of the pipeline 1.

[0051] As Figure 4 shown, the abutting portion 32 has a force that pushes against the inner wall of the pipeline 1 from the axis of the pipeline 1, and the abutting portion 32 elastically deforms along the radial direction of the pipeline 1. That is to say, the supporting device 3 and the pipeline 1 are connected in a flexible support manner. By using the elastic support method to embed the abutting portion 32 in the pipeline 1, not only can the elastic deformation of the abutting portion 32 adapt to the pipeline 1 in different states, effectively improving the adaptability of the supporting device 3, but also the operating cost of the supporting device 3 can be effectively reduced and the operation steps can be simplified without adjusting the size of the abutting portion 32 along the radial direction.

[0052] In the state where the abutting portion 32 is embedded in the pipeline 1, the abutting portion 32 can not only abut against the inner wall of the pipeline 1, but also has a force that pushes against the inner wall of the pipeline 1 from the abutting portion 32. This can not only further improve the connection stability between the supporting device 3 and the pipeline 1, but also be beneficial for the abutting portion 32 to still abut against the inner wall of the pipeline 1 when the pipeline 1 is in states such as thermal expansion and cooling contraction, avoiding the situation where the connection between the supporting device 3 and the pipeline 1 becomes unstable due to reasons such as thermal expansion and contraction.

[0053] In one example, the abutting portion 32 includes a mounting base 321, an abutting member 322, and an elastic member 323. The mounting base 321 is disposed on the supporting device 2. Opposite ends of the elastic member 323 are respectively connected to the mounting base 321 and the abutting member 322. In a state where the abutting portion 32 is embedded in the pipeline 1, the elastic member 323 forms a force that abuts against the inner wall of the pipeline 1 in a direction from the mounting base 321. The abutting member 322 abuts against the inner wall of the pipeline 1. Among them, the supporting device 2 is connected to the abutting portion through a connecting member 31. A plurality of the abutting portions 32 are arranged along the circumferential direction of the connecting member 31. In a state where the abutting portion 32 is not embedded in the pipeline 1, a side of the abutting member 322 facing away from the mounting base 321 protrudes from the connecting member 31.

[0054] As Figures 2 to 7 shown, the mounting base 321 is in a cuboid shape. The mounting base 321 is disposed on a side of the connecting member 31 facing away from the supporting device 2 through a connecting plate. The connecting plate is fixed to the connecting member 31 by bolts.

[0055] Of course, in the embodiment of the present application, the mounting base 321 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the mounting base 321 and the connecting plate can be an integrally formed structure.

[0056] The abutting member 322 is in a rectangular block shape, and a protrusion is provided on a side close to the inner wall of the pipeline 1. In a state where the abutting portion 32 is embedded in the pipeline 1, the protrusion abuts against the inner wall of the pipeline 1. The protrusion has a cut surface, and the cut surface is used to facilitate the insertion of the abutting portion 32 into the pipeline 1 when the supporting device 3 and the pipeline 1 are installed.

[0057] The elastic member 323 is a spring. The bottom of the spring is connected to the bottom of the groove, and the top of the spring is connected to a side of the abutting portion 32 facing away from the protrusion. The spring can undergo elastic deformation in the axial direction of the elastic member 323.

[0058] A groove is formed on a side of the mounting base 321 close to the inner wall of the pipeline 1. The abutting member 322 and the elastic member are both disposed in the groove, and one end of the elastic member 323 is connected to the abutting member 322. The groove is formed along the radial direction of the pipeline 1, that is to say, the abutting member 322 can slide in the groove along the radial direction of the pipeline 1.

[0059] When the supporting device 3 is connected to the pipeline 1, that is, the abutting portion 32 is embedded in the pipeline 1, the elastic member 323 exerts a force on the abutting member 322 from the axis of the pipeline 1 towards the inner wall of the pipeline 1, and the inner wall of the pipeline 1 presses against the abutting member 322 to form a force from the inner wall of the pipeline 1 towards the axis of the pipeline 1, thereby strengthening the abutting force between the abutting member 322 and the inner wall of the pipeline 1 to avoid the situation where the connection between the supporting device 3 and the pipeline 1 becomes unstable due to reasons such as thermal expansion and contraction.

[0060] As Figure 3 shown, the connecting member 31 is annular. One side of the connecting member 31 is connected to the supporting device 2, and the other side is connected to the abutting portion 32. By setting the connecting member 31 as an annular structure, it is convenient for the nozzle of the spraying device to pass through the supporting portion to perform spraying operations on the inner wall of the pipeline 1.

[0061] Of course, in the embodiment of the present application, the connecting member 31 is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the connecting member 31 can be circular, or can also be a rectangular frame or other structures.

[0062] A plurality of abutting portions 32 are provided on the side of the connecting member 31 facing away from the supporting device 2, and the plurality of abutting portions 32 are arranged along the circumferential direction of the connecting member 31. By providing a plurality of abutting portions 32 to abut against the inner wall of the pipeline 1, the connection stability between the supporting device 3 and the pipeline 1 is effectively improved.

[0063] By providing a plurality of abutting portions 32 on the connecting member 31 to form a plurality of forces that push against the inner wall of the pipeline 1 from the axis of the pipeline 1, the connection stability between the supporting device 3 and the pipeline 1 is effectively improved.

[0064] In one example, the abutting portion 32 further includes a guide pin 324, the guide pin 324 is provided on the mounting seat 321, the abutting member 322 has a guide groove 325 extending along the mounting seat 321 towards the inner wall of the pipeline 1, and the guide pin 324 is slidably engaged with the guide groove 325.

[0065] As Figure 3 shown, a guide pin 324 is provided in the groove. A guide groove 325 is provided on the side of the abutting member 322 connected to the elastic member 323, and the position of the guide groove 325 corresponds to that of the guide pin 324.

[0066] That is to say, the bottom of the guide pin 324 is fixed in the groove, the top of the guide pin 324 is inserted into the guide groove 325. When the abutting member 322 moves in the radial direction of the pipeline 1 through the elastic member 323, the guide pin 324 and the guide groove 325 form a guiding fit to limit the movement direction of the abutting block and prevent the abutting block from shifting and affecting the connection stability between the supporting device 3 and the pipeline 1.

[0067] In one example, a plurality of the guide pins 324 are provided on the mounting base 321, a plurality of the guide grooves 325 corresponding to the guide pins 324 are formed on the abutting member 322, and the plurality of the guide pins 324 are arranged circumferentially around the elastic member 323 with the elastic member 323 as the center.

[0068] As Figure 3 shown, a plurality of guide pins 324 are provided in the groove to prevent the abutting member 322 from rotating in the groove, improve the stability of the abutting member 322 in the groove, and further improve the stability of the connection between the supporting device 3 and the pipeline 1.

[0069] In the embodiment of the present application, the groove is rectangular, and the plurality of guide pins 324 are distributed in a rectangular array with the elastic member 323 as the center.

[0070] Of course, in the embodiment of the present application, the groove is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the groove is a circular groove, and the plurality of guide pins 324 are distributed in a circular array with the elastic member 323 as the center.

[0071] In one example, the support device 2 includes a rotating part 21, the supporting device 3 is arranged at the rotating end of the rotating part 21, and the rotating part 21 drives the supporting device 3 to rotate around the axis of the connecting member 31.

[0072] As Figures 2 to 7 shown, the rotating end of the rotating part 21 is connected to the supporting device 3. That is, the rotating part 21 is arranged on the side of the connecting member 31 away from the abutting part 32. The rotating part 21 can rotate around the axis of the connecting member 31.

[0073] When the supporting device 3 is connected to the pipeline 1, the rotation of the rotating part 21 can drive the supporting device 3 to rotate, and further drive the pipeline 1 to rotate itself, which is beneficial to uniformly spraying the pipeline 1 during the operation and improving the spraying quality.

[0074] In one example, the rotating part 21 includes a first housing 211, a first driving member 212 and a rotating member 213. The first driving member 212 is arranged in the first housing 211. One end of the rotating member 213 extends out of the first housing 211 and is connected to the connecting member 31. The rotating member 213 is connected to the first driving member 212, and the first driving member 212 drives the rotating member 213 to rotate around the axis of the pipeline 1; wherein, a bearing 214 is arranged in the first housing 211, and the end of the rotating member 213 away from the connecting member 31 is inserted into the bearing 214.

[0075] As Figure 6As shown, the rotating part 21 includes a first housing 211. A first driving member 212 and a rotating member 213 are arranged inside the first housing 211. The driving end of the first driving member 212 is in transmission connection with the rotating member 213, so as to drive the rotating member 213 to rotate through the first driving member 212, and further drive the supporting device 3 to rotate through the rotating member 213.

[0076] The rotating member 213 is tubular. One end of the rotating member 213 extends out of the first housing 211 and is connected to the connecting member 31.

[0077] A bearing 214 is arranged inside the first housing 211. One end of the rotating member 213 away from the connecting member 31 is inserted into the bearing 214, so as to facilitate driving the rotating member 213 to rotate through the first driving member 212.

[0078] The first housing 211 has an opening, and the opening communicates with the pipe hole of the rotating member 213, so as to facilitate that during the spraying operation, the nozzle of the spraying device passes through the opening and through the rotating member 213 to extend into the pipe 1 for spraying the inner wall of the pipe 1.

[0079] In one example, the first driving member 212 includes a driver 2121, a driving gear 2122 and a driven gear 2123. The driver 2121 is arranged inside the first housing 211. The driving gear 2122 is arranged at the driving end of the driver 2121. The driven gear 2123 is sleeved on the rotating member 213, and the driving gear 2122 is in meshing transmission with the driven gear 2123.

[0080] As Figure 6 As shown, the driver 2121 is a motor, and the driver 2121 is arranged below the rotating member 213. A driving gear 2122 is arranged at the driving end of the driver 2121, and a driven gear 2123 is sleeved on the rotating member 213. The driving gear 2122 is in meshing with the driven gear 2123. When the driver 2121 is started, the driving gear 2122 drives the driven gear 2123 to act, so as to drive the rotating member 213 to rotate, thereby driving the supporting device 3 to rotate. By driving the supporting device 3 to rotate through the first driving member 212, the pipe 1 is further driven to rotate, so as to facilitate full spraying of the pipe 1 and prevent uneven spraying or the need for secondary repair.

[0081] In one example, the support device 2 further includes a first driving part 22. The rotating part 21 is arranged at the driving end of the first driving part 22. The first driving part 22 drives the rotating part 21 to move in a first direction, and the first direction extends perpendicular to the axial direction of the pipeline 1; the first driving part 22 includes a second housing 221 and a second driving member 222; the second driving member 222 is arranged in the second housing 221, the second driving member 222 is connected to the rotating part 21, and the second driving member 222 drives the rotating part 21 to move in the first direction

[0082] As Figures 3 to 7 described, the first direction is the height direction of the support device 2, that is, the direction perpendicular to the axial extension of the pipeline 1. By connecting the first driving part 22 with the rotating part 21, the position of the supporting device 3 in the height direction is adjusted

[0083] In the state where the supporting device 3 is not connected to the pipeline 1, the first driving part 22 drives the rotating part 21 up or down to adjust the position of the supporting device 3 in the height direction so that the supporting device 3 is aligned with the port of the pipeline 1, facilitating the insertion of the abutting part 32 into the pipeline 1

[0084] In the state where the supporting device 3 is connected to the pipeline 1, the first driving part 22 drives the rotating part 21 up or down to drive the pipeline 1 to be adjusted in the height direction through the supporting device 3, facilitating the alignment of the pipeline 1 with the nozzle of the spraying device, so that the nozzle passes through the rotating member 213 and extends into the pipeline 1 to spray the inner wall of the pipeline 1

[0085] As Figures 3 to 7 shown, the first driving part 22 includes a second housing 221 and a second driving member 222

[0086] The second housing 221 is a rectangular housing with an opening at the top. The bottom of the first housing 211 is located inside the second housing 221. The driving end of the second driving member 222 is connected to the bottom of the first housing 211. By driving the second driving member 222, the first housing 211 is raised and lowered, thereby realizing the adjustment of the rotating part 21 in the height direction

[0087] The second driving member 222 can use a ball screw to drive the rotating part 21 to lift. In the state where the supporting device 3 is not connected to the pipeline 1, the second driving member 222 is used to raise and lower the rotating part 21 to adjust the position of the supporting device 3 in the height direction, facilitating the insertion of the abutting part 32 into the pipeline 1. In the state where the supporting device 3 is connected to the pipeline 1, the second driving member 222 drives the supporting device 3 to be adjusted in the height direction, and then adjusts the position of the pipeline 1 in the height direction, facilitating the alignment of the pipe orifice of the pipeline 1 with the nozzle of the spraying device, so that the nozzle extends into the pipeline 1 to spray the inner wall of the pipeline 1

[0088] In one example, the support device 2 further includes a second driving part 23. The driving end of the first driving part 22 is connected to the driving end of the second driving part 23. The second driving part 23 drives the first driving part 22 to move in a second direction, and the second direction is parallel to the axial extension direction of the pipeline 1 and perpendicular to the first direction.

[0089] As Figures 3 to 7 As shown, the support device 2 further includes a second driving part 23. The second driving part 23 can drive the first driving part 22 to move in a second direction. The rotating part 21 is arranged at the driving end of the first driving part 22, and then the second driving part 23 drives the first driving part 22 to act, so as to realize the position adjustment of the supporting device 3 in the second direction. The second direction is the length direction of the support device 2, that is, the length direction of the support device 2 is parallel to the axial extension direction of the pipeline 1 and perpendicular to the height direction of the support device 2.

[0090] In the state where the supporting device 3 is not connected to the pipeline 1, the second driving part 23 drives the first driving part 22 to move along the length direction of the pipeline 1, so as to facilitate the adjustment of the distance between the supporting device 3 and the port of the pipeline 1. When the supporting device 3 needs to be connected to the pipeline 1, the second driving part 23 drives the first driving part 22 to approach the pipeline 1 until the abutting part 32 is embedded in the pipeline 1. When the supporting device 3 needs to be disassembled from the pipeline 1, the second driving part 23 drives the first driving part 22 to move in a direction away from the pipeline 1. Moreover, the second driving part 23 drives the first driving part 22 to adjust the distance between the supporting device 3 and the port of the pipeline 1, so as to adapt to pipelines 1 of different lengths, effectively improving the adaptability of the spraying clamping mechanism.

[0091] In one example, the second driving part 23 includes a carrier plate 231, a third driving member 232 and a connecting rod 233. The third driving member 232 is arranged on the carrier plate 231. The third driving member 232 and the first driving part 22 are respectively connected to opposite ends of the connecting rod 233. Wherein, the carrier plate 231 is provided with a slide rail, and the extension direction of the slide rail is parallel to the axial direction of the pipeline 1. The first driving member 212 drives the second driving part 23 to move along the slide rail.

[0092] As Figures 3 to 7 As shown, the second driving part 23 includes a carrier plate 231. The carrier plate 231 is provided with a slide rail, and the slide rail extends in the second direction. The second housing 221 is arranged on the carrier plate 231 and can move along the slide rail.

[0093] The third driving member 232 is a hydraulic cylinder. A connecting rod 233 is connected to the driving end of the hydraulic cylinder. The other end of the connecting rod 233 is connected to the second housing 221. The hydraulic cylinder drives the connecting rod 233 to act, so as to drive the second housing 221 to slide along the slide rail, thereby realizing that the second housing 221 drives the rotating part 21 to act, and further adjusting the distance between the supporting device 3 and the port of the pipeline 1.

[0094] Rollers are arranged at the bottom of the bearing plate 231. In the state where the supporting device 3 is connected to the pipeline 1, the bearing plate 231 can drive the first driving part 22, the second driving part 23, the rotating part 21, the supporting device 3 and the pipeline 1 to move through the rollers, so as to convey and move the pipeline 1 for spraying operations.

[0095] In the embodiment of the present application, the pipeline 1 is a straight pipe, and supporting devices 3 are respectively connected to the opposite ends of the pipeline 1, and the two supporting devices 3 are symmetrically arranged. By respectively connecting the two supporting devices 2 to the two supporting devices 3, it is not only beneficial to improve the stability of the pipeline 1 during movement, but also convenient to adjust the distance between the two supporting devices 2 according to different length dimensions of the pipeline 1, effectively improving the adaptability of the spraying clamping mechanism.

[0096] Of course, in the embodiment of the present application, the connection of the pipeline is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the pipeline 1 can also be a bent pipe, a tee pipe or a cross pipe, etc.

[0097] In the embodiment of the present application, the pipeline 1 is a straight pipe, and the spraying clamping mechanisms are respectively arranged at the opposite ends of the pipeline 1, and a connecting frame is arranged between the two spraying clamping mechanisms. The opposite ends of the connecting frame along the length direction of the pipeline 1 are respectively connected to the two relatively arranged bearing plates 231. By arranging the connecting frame between the two spraying clamping mechanisms, the two spraying clamping mechanisms can run synchronously when conveying the pipeline 1, effectively improving the connection stability between the two spraying clamping mechanisms and the pipeline 1.

[0098] Although some specific embodiments of the present application have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
