Description

Technical Field

[0001] The present invention relates to the technical field of pipeline construction, and particularly to an auxiliary tooling for patchwork operation. Background Art

[0002] The patchwork technology refers to a technology that, after the welding of metal structures such as pipelines and storage tanks is completed, performs local heat treatment or protective treatment on the weld seam and its heat-affected zone to eliminate welding residual stress, improve the performance of the welded joint, prevent corrosion, or increase the overall service life of the structure. It is widely used in industries such as petroleum, chemical industry, electric power, and shipbuilding, and is an important link to ensure the safe and reliable operation of welded structures.

[0003] Currently, the patchwork operation mostly adopts a fully manual operation mode or a semi-automatic operation mode. Among them, the fully manual operation mode is to use manual handheld equipment to perform operations on each process. On the one hand, this mode will lead to low operation efficiency and increase the labor cost of the operation. On the other hand, since the operation quality overly depends on the technical level of the operator and environmental conditions, it is difficult to maintain the construction quality of each process stably. The semi-automatic operation mode is to use automated equipment to perform operations on some processes. Although it improves the construction efficiency and reduces the construction cost, some processes still need to be constructed, and it is still impossible to ensure the consistency of the patchwork quality and the patchwork quality of each part of the pipeline, leaving potential hidden dangers for the long-term safe operation of the pipeline system.

[0004] Therefore, there is an urgent need for an auxiliary tooling for patchwork operation to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary tooling for patchwork operation, which reduces the labor cost of patchwork operation, improves the automation degree of pipeline patchwork operation, and ensures the quality of pipeline patchwork.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0008] A bracket, including a first arc-shaped member, and both ends of the first arc-shaped member are provided with second arc-shaped members hinged thereto. The two second arc-shaped members have an operating state of contacting each other and a moving state of separating from each other. In the operating state, the first arc-shaped member and the two second arc-shaped members enclose an operating space, and the pipeline can pass through the operating space;

[0009] The driving mechanism includes a first driving member and a plurality of arc-shaped connecting members. Arc-shaped connecting members are provided on both the first arc-shaped member and the second arc-shaped member, and the circumferential position of the arc-shaped connecting members along the pipeline is adjustable. The first driving member is arranged on the bracket. In the working state, the plurality of arc-shaped connecting members are mutually attached and form a track extending along the circumferential direction of the pipeline. The output end of the first driving member can selectively be in transmission connection with any one of the arc-shaped connecting members, and is used to drive the arc-shaped connecting member connected thereto to move along the extending direction of the track;

[0010] A plurality of functional modules can be selectively installed on several arc-shaped connecting members and are detachably connected to the arc-shaped connecting members.

[0011] Optionally, the driving mechanism further includes a transmission gear. A plurality of connecting teeth are provided on the arc-shaped connecting member, and the plurality of connecting teeth are continuously arranged along the extending direction of the arc-shaped connecting member. The transmission gear meshes with the connecting teeth, and the output end of the first driving member is connected to the transmission gear. In the working state, the first driving member drives the transmission gear to rotate, and the transmission gear drives the arc-shaped connecting member to move through the connecting teeth.

[0012] Optionally, a chute extending along its extending direction is provided on the bracket, and a sliding portion is provided on the arc-shaped connecting member. The sliding portion is in sliding fit with the chute.

[0013] Optionally, a plurality of limiting members are provided on both the first arc-shaped member and the second arc-shaped member. The plurality of limiting members are arranged at intervals along the circumferential direction of the pipeline. Grooves are provided on the limiting members, and the plurality of grooves form a chute. The sliding portion is in sliding fit with the grooves.

[0014] Optionally, the auxiliary tooling for joint coating operation further includes a plurality of first clamping members arranged on the bracket. The first clamping members protrude radially from the bracket along the pipeline. In the working state, the first clamping members can be attached to the outer wall of the pipeline;

[0015] And / or, the auxiliary tooling for joint coating operation further includes a plurality of second clamping members. The second clamping members are movably arranged on the bracket along the radial direction of the pipeline. In the working state, the second clamping members can be attached to the outer wall of the pipeline.

[0016] Optionally, the auxiliary tooling for joint coating operation further includes a locking assembly. The locking assembly is arranged on the second arc-shaped member and is used to limit the two second arc-shaped members in the working state.

[0017] Optionally, the locking assembly includes a locking groove and a locking buckle. The locking groove is arranged on one of the two second arc-shaped members, and the locking buckle is rotatably arranged on the other of the two second arc-shaped members. By driving the locking buckle to rotate, the locking buckle can be inserted into or disengaged from the locking groove.

[0018] Optionally, a guiding member is provided on one of the two second arc-shaped members. The guiding member is located at one end of the corresponding second arc-shaped member away from the first arc-shaped member, and a guiding inclined surface is provided on the guiding member. When the second arc-shaped member switches from the moving state to the working state, the other of the two second arc-shaped members can move along the guiding inclined surface.

[0019] Optionally, the auxiliary tooling for joint coating operation further includes two third driving members provided on the first arc-shaped member. The two third driving members correspond to the two second arc-shaped members one by one.

[0020] Optionally, the auxiliary tooling for joint coating operation further includes a traveling assembly, and the traveling assembly is provided on the bracket.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] The present invention provides an auxiliary tooling for joint coating operation, which can move along the axial direction of the pipeline, so that it can move to the interfaces of any two adjacent pipelines for joint coating operation. The second arc-shaped member is hinged to the first arc-shaped member, that is, the second arc-shaped member can rotate relative to the first arc-shaped member, so that the second arc-shaped member can switch between the operation state and the moving state. When the two second arc-shaped members are switched to the separated moving state, the distance between the second arc-shaped member and the pipeline increases, effectively avoiding the collision between the bracket and the pipeline during the moving process, and ensuring the safety of the pipeline and the bracket during use. Before the joint coating operation, the two second arc-shaped members are first switched to the operation state. The first arc-shaped member and the two second arc-shaped members are both arc-shaped and can adapt to the cross-sectional shape of the pipeline, so that there is no relative movement between the bracket and the pipeline in the operation state, ensuring the joint coating quality. In the operation state, multiple arc-shaped connecting members are attached to each other to form a track. Therefore, when the first driving member drives the arc-shaped connecting member connected to it to move, the arc-shaped connecting member connected to the first driving member can push the arc-shaped connecting member connected to it to move together, so that multiple arc-shaped connecting members can all move along the extension direction of the track, and the functional module installed on the arc-shaped connecting member can also move along the extension direction of the track, that is, the functional module can perform joint coating operation on the pipeline along the circumferential direction of the pipeline. During the joint coating operation, the functional module can only move driven by the arc-shaped connecting member, which not only ensures the stability of the moving path and moving speed of the functional module, but also ensures that the distance between the functional module and the pipeline in the radial direction of the pipeline will not change, improving the stability of the joint coating process, so that the treatment effects of the functional module on each position along the circumferential direction of the pipeline can be the same, ensuring that the joint coating quality of each part along the circumferential direction of the pipeline and the joint coating quality of the interfaces of any two adjacent pipelines can meet the requirements. The functional module is detachably connected to the driving mechanism. During the joint coating operation, the staff can install the functional module with the corresponding function on the driving mechanism according to the required processes, and the operation of replacing the functional module is convenient and fast, enabling multi-process joint coating operation on the auxiliary tooling, reducing the number of equipment required for joint coating operation, improving the efficiency of pipeline joint coating operation, and reducing the cost of joint coating operation.

[0044] As Figures 1 to 9 shown, this embodiment provides an auxiliary tooling for the joint coating operation, which reduces the labor cost of the joint coating operation, improves the automation degree of the joint coating operation of the pipeline 100, and ensures the quality of the joint coating of the pipeline 100.

[0045] Refer to Figure 3 、 Figure 4 and Figure 5The auxiliary tooling for patching operation can be movably installed on the pipeline 100 along the axial direction of the pipeline 100, including a bracket 1, a driving mechanism 2 and multiple functional modules (not shown in the figure), the bracket 1 includes a first arc-shaped member 11, and both ends of the first arc-shaped member 11 are provided with a second arc-shaped member 12 hinged thereto, and the two second arc-shaped members 12 have an operating state of mutual contact and a moving state of mutual separation. In the operating state, the first arc-shaped member 11 and the two second arc-shaped members 12 enclose a working space 13, and the pipeline 100 can be passed through the working space 13; the driving mechanism 2 includes a first driving member 21 and multiple arc-shaped connecting members 221 , the first arc-shaped member 11 and the second arc-shaped member 12 are both provided with an arc-shaped connecting member 221, and the position of the arc-shaped connecting member 221 along the circumference of the pipeline 100 is adjustable, and the first driving member 21 is provided on the bracket 1. In the working state, multiple arc-shaped connecting members 221 are attached to each other and form a track 22 extending along the circumference of the pipeline 100. The output end of the first driving member 21 can be selectively connected to any arc-shaped connecting member 221 for driving the arc-shaped connecting member 221 connected thereto to move along the extension direction of the track 22; multiple functional modules can be selectively installed on several arc-shaped connecting members 221 and be detachably connected to the arc-shaped connecting members 221.

[0046] The auxiliary tooling for joint repair operation provided in this embodiment can move along the axial direction of the pipeline 100, so that it can move to the interface between any two adjacent pipelines 100 for joint repair operation. The second arc-shaped member 12 is hinged to the first arc-shaped member 11, that is, the second arc-shaped member 12 can rotate relative to the first arc-shaped member 11, so that the second arc-shaped member 12 can be switched between the operation state and the moving state. When the two second arc-shaped members 12 are switched to the separated moving state, the distance between the second arc-shaped member 12 and the pipeline 100 increases, effectively avoiding the collision between the bracket 1 and the pipeline 100 during the movement, and ensuring the safety of the use of the pipeline 100 and the bracket 1. Before the joint repair operation, the two second arc-shaped members 12 are first switched to the operation state. The first arc-shaped member 11 and the two second arc-shaped members 12 are both arc-shaped and can adapt to the cross-sectional shape of the pipeline 100, so that there is no relative movement between the bracket 1 and the pipeline 100 in the operation state, ensuring the joint repair quality. In the operation state, a plurality of arc-shaped connecting members 221 are mutually attached to form a track 22. Therefore, when the first driving member 21 drives the arc-shaped connecting member 221 connected thereto to move, the arc-shaped connecting member 221 connected to the first driving member 21 can push the arc-shaped connecting member 221 connected thereto to move together. Thus, a plurality of arc-shaped connecting members 221 can all move along the extending direction of the track 22, so that the functional module installed on the arc-shaped connecting member 221 can also move along the extending direction of the track 22, that is, the functional module can perform joint repair operation on the pipeline 100 along the circumferential direction of the pipeline 100. During the joint repair operation, the functional module can only move driven by the arc-shaped connecting member 221, which not only ensures the stability of the moving path and moving speed of the functional module, but also ensures that the distance between the functional module and the pipeline 100 in the radial direction of the pipeline 100 does not change, improving the stability of the joint repair process, so that the treatment effects of the functional module on each position along the circumferential direction of the pipeline 100 can be the same, ensuring that the joint repair quality of each part along the circumferential direction of the pipeline 100 and the joint repair quality at the interface between any two adjacent pipelines 100 can meet the requirements. The functional module is detachably connected to the driving mechanism 2. During the joint repair operation, the staff can install the functional module with the corresponding function on the driving mechanism 2 according to the required process, and the operation of replacing the functional module is convenient and fast, enabling multi-process operation of joint repair on the auxiliary tooling, reducing the number of equipment required for joint repair operation, improving the efficiency of the joint repair operation of the pipeline 100, and reducing the cost of the joint repair operation.

[0047] Specifically, referring to Figure 4 , both the first arc-shaped member 11 and the second arc-shaped member 12 are made of arc-shaped plates. In the operation state, the sides of the two second arc-shaped members 12 facing each other are attached, and the first arc-shaped member 11 and the two second arc-shaped members 12 form a bracket 1 with a circular ring cross-sectional shape, and the inner hole of the circular ring is the operation space 13.

[0048] Exemplarily, the multiple functional modules include a rust removal module, a painting module, and a heat shrink sleeve module 6. The rust removal module is configured to remove rust from the surface of the pipeline 100, the painting module is configured to paint the surface of the pipeline 100, and the heat shrink sleeve module 6 is configured to lay a heat shrink tape on the surface of the pipeline 100. Refer to Figure 2 and Figure 9 , the functional module shown is the heat shrink sleeve module 6. The heat shrink sleeve module 6 includes a feeding roller 61, a heating element 62, and a pressing roller 63. The heat shrink tape is installed on the feeding roller 61. When the arc-shaped connecting member 221 moves, the arc-shaped connecting member 221 can drive the feeding roller 61, the heating element 62, and the pressing roller 63 to move simultaneously. The heat shrink tape is first laid flat on the pipeline 100 from the feeding roller 61. Subsequently, the heating element 62 can immediately heat the heat shrink tape laid flat on the pipeline 100. The heat shrink tape shrinks and can adhere to the pipeline 100. Finally, the pressing roller 63 can squeeze the heat shrink tape adhered to the pipeline 100 to extrude the air bubbles between the heat shrink tape and the pipeline 100, thereby completing the process of installing the heat shrink tape.

[0049] In this embodiment, the arc lengths and bending radian of the first arc-shaped member 11 and the second arc-shaped member 12 are the same. There is one arc-shaped connecting member 221 provided on the first arc-shaped member 11, and there is one arc-shaped connecting member 221 provided on each second arc-shaped member 12. The arc length and bending radian of the arc-shaped connecting member 221 are the same as those of the first arc-shaped member 11. Thus, when the first driving member 21 drives the arc-shaped connecting member 221 connected thereto to move, any arc-shaped connecting member 221 can move to the first arc-shaped member 11 and the second arc-shaped member 12. In the working state, the end face of any arc-shaped connecting member 221 can contact and closely fit with the end face of the adjacent arc-shaped connecting member 221, thereby forming a circular and continuous track 22 with a cross-sectional shape, enabling the functional module to move to any position in the circumferential direction of the pipeline 100; in the moving state, the arc-shaped connecting member 221 located on the second arc-shaped member 12 rotates relative to the first arc-shaped member 11 under the drive of the second arc-shaped member 12, and the three arc-shaped connecting members 221 are separated from each other.

[0050] Exemplarily, refer to Figure 5 , the first driving member 21 is provided on the first arc-shaped member 11 and will not move whether in the working state or the moving state.

[0051] In this embodiment, refer to Figure 1 , the bracket 1 further includes a rotating shaft 14. There is a first connection hole provided on the first arc-shaped member 11, and a second connection hole provided on the second arc-shaped member 12. The rotating shaft 14 passes through the first connection hole and the second connection hole and is rotatably matched with both the first connection hole and the second connection hole, thereby realizing the hinge connection between the first arc-shaped member 11 and the second arc-shaped member 12.

[0052] Furthermore, anti-disengagement members are provided at both ends of the rotating shaft 14. The anti-disengagement members are located on the sides of the first arc-shaped member 11 and the second arc-shaped member 12 that face away from each other to prevent the rotating shaft 14 from disengaging from the first connection hole and the second connection hole.

[0053] Optionally, referring to Figure 4 and Figure 5 , the driving mechanism 2 further includes a transmission gear 23. A plurality of connecting teeth 2211 are provided on the arc-shaped connecting member 221. The plurality of connecting teeth 2211 are continuously arranged along the extending direction of the arc-shaped connecting member 221. The transmission gear 23 meshes with the connecting teeth 2211. The output end of the first driving member 21 is connected to the transmission gear 23. In the working state, the first driving member 21 drives the transmission gear 23 to rotate, and the transmission gear 23 drives the arc-shaped connecting member 221 to move through the connecting teeth 2211. With such an arrangement, not only the movement of the arc-shaped connecting member 221 on the bracket 1 is realized, but also the stability of the movement of the arc-shaped connecting member 221 can be ensured; moreover, the energy loss of the first driving member 21 can be reduced through the transmission mode of the transmission gear 23 meshing with the connecting teeth 2211, and the efficient transmission of power can be achieved.

[0054] Exemplarily, the first driving member 21 is a motor, the arc-shaped connecting member 221 is an arc-shaped rack, and the connecting teeth 2211 are the teeth on the rack. In the working state, the end faces of adjacent racks are closely attached.

[0055] Optionally, a chute extending along its extending direction is provided on the bracket 1, and a sliding portion 2212 is provided on the arc-shaped connecting member 221. The sliding portion 2212 is in sliding fit with the chute. With such an arrangement, relative sliding occurs between the arc-shaped connecting member 221 and the bracket 1 when the arc-shaped connecting member 221 moves, which helps to reduce the friction between the arc-shaped connecting member 221 and the bracket 1, reduce the energy consumption of the first driving member 21, and improve the efficiency of the joint coating operation.

[0056] In this embodiment, referring to Figure 2 , Figure 4 and Figure 6 , a plurality of limiting members 151 are provided on both the first arc-shaped member 11 and the second arc-shaped member 12. The plurality of limiting members 151 are arranged at intervals along the circumferential direction of the pipeline 100. Grooves 1511 are provided on the limiting members 151. The plurality of grooves 1511 form a chute, and the sliding portion 2212 is in sliding fit with the grooves 1511. The grooves 1511 enable the arc-shaped connecting member 221 to move along the circumferential direction of the pipeline 100 on the bracket 1, and at the same time can restrict the position of the arc-shaped connecting member 221 on the bracket 1 to prevent the arc-shaped connecting member 221 from separating from the bracket 1 during the movement.

[0057] Furthermore, referring to Figure 4 and Figure 6, a plurality of cushion blocks 152 are further arranged on the first arc-shaped member 11 and the second arc-shaped member 12. The plurality of cushion blocks 152 correspond to the plurality of limiting members 151 one by one. The cushion blocks 152 are clamped between the arc-shaped connecting member 221 and the first arc-shaped member 11 or the second arc-shaped member 12 and are in sliding fit with the arc-shaped connecting member 221. The arrangement of the cushion blocks 152 can reduce the friction between the arc-shaped connecting member 221 and the first arc-shaped member 11 and the second arc-shaped member 12, make the movement of the arc-shaped connecting member 221 smoother, and reduce the energy consumption of the first driving member 21.

[0058] Exemplarily, referring to Figure 5 and Figure 6 , the sliding portion 2212 and the connecting teeth 2211 are respectively arranged on both sides of the arc-shaped connecting member 221 along its width direction to prevent the sliding portion 2212 from affecting the meshing of the connecting teeth 2211 with the transmission gear 23; the cushion block 152 is located on one side of the connecting teeth 2211 and is clamped between the arc-shaped connecting member 221 and the first arc-shaped member 11 or the second arc-shaped member 12 along the thickness direction of the arc-shaped connecting member 221, so that the frictions on both sides of the arc-shaped connecting member 221 along its width direction can be the same to ensure the stability of the movement of the arc-shaped connecting member 221.

[0059] In other embodiments, an installation groove extending along its circumferential direction is arranged on the inner hole wall of the annular bracket 1. The sliding portion 2212 of the arc-shaped connecting member 221 is embedded in the installation groove and is in sliding fit with the installation groove, and the connecting teeth 2211 extend out of the installation groove to avoid affecting the meshing of the connecting teeth 2211 with the transmission gear 23.

[0060] In an alternative embodiment, referring to Figure 2 and Figure 4 , the auxiliary tooling for joint coating operation further includes a plurality of first clamping members 121 arranged on the bracket 1. The first clamping members 121 protrude from the bracket 1 along the radial direction of the pipeline 100. In the working state, the first clamping members 121 can be attached to the outer wall of the pipeline 100. The first clamping members 121 protrude from the bracket 1, so that the distance between the first clamping members 121 and the outer wall of the pipeline 100 can be smaller than that of the first arc-shaped member 11 and the second arc-shaped member 12, so that it can be attached to the outer wall of the pipeline 100 in the working state, ensuring that the pipeline 100 can be stably limited in the working space 13, improving the restraint effect on the pipeline 100, improving the stability of the joint coating process, and ensuring the quality of the joint coating.

[0061] In this embodiment, referring to Figure 2 and Figure 4, the first clamping member 121 includes a first arc-shaped clamping surface 1211, and the first arc-shaped clamping surface 1211 is located on the side of the bracket 1 facing the pipeline 100, so that the first arc-shaped clamping surface 1211 can be attached to the outer wall of the pipeline 100 during the operation state; moreover, the first arc-shaped clamping surface 1211 is set to be arc-shaped, which can also ensure the tightness of its attachment to the outer wall of the pipeline 100 and improve the clamping effect of the first clamping member 121 on the pipeline 100.

[0062] In another alternative embodiment, refer to Figure 2 and Figure 4 , the auxiliary tooling for joint coating operation further includes a plurality of second clamping members 111, and the second clamping members 111 are movably arranged on the bracket 1 along the radial direction of the pipeline 100. During the operation state, the second clamping members 111 can be attached to the outer wall of the pipeline 100. By driving the second clamping members 111 to move along the radial direction of the pipeline 100, the distance between the second clamping members 111 and the outer wall of the pipeline 100 can be adjusted, so that the second clamping members 111 can be closely attached to the outer wall of the pipeline 100. The second clamping members 111 are attached to the pipeline 100, so that the pipeline 100 can be stably limited in the operation space 13, improving the restraint effect on the pipeline 100, enhancing the stability of the joint coating process, and ensuring the quality of the joint coating.

[0063] Specifically, refer to Figure 2 and Figure 4 , the second clamping member 111 includes a second arc-shaped clamping surface 1111, and the second arc-shaped clamping surface 1111 is located on the side of the bracket 1 facing the pipeline 100, so that the second arc-shaped clamping surface 1111 can be attached to the outer wall of the pipeline 100 during the operation state; moreover, the second arc-shaped clamping surface 1111 is set to be arc-shaped, which can also ensure the tightness of its attachment to the outer wall of the pipeline 100 and improve the clamping effect of the second clamping member 111 on the pipeline 100.

[0064] In this embodiment, refer to Figure 2 and Figure 7 , a second driving member 112 is arranged on the bracket 1, and the output end of the second driving member 112 is connected to the second clamping member 111 for driving the second clamping member 111 to move along the radial direction of the pipeline 100.

[0065] Exemplarily, the second driving member 112 adopts an electric push rod.

[0066] In another alternative embodiment, refer to Figure 2 and Figure 7, on the support 1, a plurality of first clamping members 121 are provided, and a plurality of second clamping members 111 are also provided. The plurality of first clamping members 121 and the plurality of second clamping members 111 are arranged at intervals along the circumferential direction of the pipeline 100. After the second arc-shaped member 12 is switched to the working state, first ensure that the pipeline 100 can be attached to the first clamping member 121, and then drive the second clamping member 111 to move to be attached to the pipeline 100, so as to ensure that the pipeline 100 can be clamped along its circumferential direction.

[0067] In this embodiment, referring to Figure 2 and Figure 7 , one second clamping member 111 is provided on the first arc-shaped member 11, and one first clamping member 121 is provided on each second arc-shaped member 12. In the working position, the arc length between any first clamping member 121 and the second clamping member 111 and the arc length between two first clamping members 121 are the same, so as to ensure the uniformity of clamping the pipeline 100.

[0068] Optionally, referring to Figure 7 and Figure 8 , the auxiliary tooling for joint coating operation further includes a locking assembly 3. The locking assembly 3 is arranged on the second arc-shaped member 12 and is used to limit the two second arc-shaped members 12 in the working state, so as to prevent the two second arc-shaped members 12 from separating from each other during the joint coating operation, and ensure the stability of the installation and operation of the functional module during the joint coating operation.

[0069] In this embodiment, referring to Figure 8 , the locking assembly 3 includes a locking groove 31 and a locking buckle 32. The locking groove 31 is arranged on one of the two second arc-shaped members 12, and the locking buckle 32 is rotatably arranged on the other of the two second arc-shaped members 12. Driving the locking buckle 32 to rotate, the locking buckle 32 can be engaged with or disengaged from the locking groove 31. When the locking buckle 32 is engaged with the locking groove 31, the relative position between the two second arc-shaped members 12 is fixed, and the second arc-shaped member 12 is limited in the working state; when the locking buckle 32 disengages from the locking groove 31, the positions of the two second arc-shaped members 12 are no longer restricted and can be switched to the moving state. The method of using the locking buckle 32 and the locking groove 31 to lock the position of the second arc-shaped member 12 is convenient and fast to operate, and is convenient for use at the construction site.

[0070] Optionally, referring to Figure 7 and Figure 8, a guiding member 122 is provided on one of the two second arc-shaped members 12. The guiding member 122 is located at one end of the corresponding second arc-shaped member 12 away from the first arc-shaped member 11, and a guiding inclined surface 1221 is provided on the guiding member 122. When the second arc-shaped member 12 switches from the moving state to the working state, the other of the two second arc-shaped members 12 can move along the guiding inclined surface 1221. With such a setting, when the second arc-shaped member 12 switches from the moving state to the working state, the staff only needs to control the rotation of the second arc-shaped member 12, without specifically observing the contact situation of the two second arc-shaped members 12, reducing the difficulty for the staff to operate the state switch of the second arc-shaped member 12 and improving the rate of the state switch of the second arc-shaped member 12.

[0071] In this embodiment, guiding members 122 are provided on both sides of the second arc-shaped member 12 along its thickness direction, and the guiding inclined surface 1221 gradually moves away from the guiding member 122 on the other side along the direction away from the second arc-shaped member 12 where it is located. The second arc-shaped member 12 without the guiding member 122 can enter between the guiding members 122 on both sides when switching from the moving state to the working state, and contact the second arc-shaped member 12 provided with the guiding member 122 under the guidance of the guiding inclined surface 1221, and will not disengage from between the guiding members 122 on both sides under the restraint of the guiding members 122 on both sides, which helps to achieve a rapid switch of the state of the second arc-shaped member 12.

[0072] Optionally, referring to Figure 2 and Figure 7 , the auxiliary tooling for the joint coating operation further includes two third driving members 16 provided on the first arc-shaped member 11. The two third driving members 16 correspond to the two second arc-shaped members 12 one by one. The output end of the third driving member 16 is connected to the corresponding second arc-shaped member 12, and is used to drive the corresponding second arc-shaped member 12 to rotate relative to the first arc-shaped member 11, so as to realize the automatic switch of the second arc-shaped member 12 between the working state and the moving state, improving the automation degree of the joint coating operation and the operation efficiency. In addition, the third driving member 16 can also keep the second arc-shaped member 12 in the working state to ensure the restraint effect of the bracket 1 on the pipeline 100 in the working state.

[0073] Exemplarily, the third driving member 16 adopts an electric push rod, and the output end of the third driving member 16 is rotatably connected to the second arc-shaped member 12. When the push rod of the electric push rod extends, the second arc-shaped member 12 switches from the moving state to the working state; when the push rod of the electric push rod retracts, the second arc-shaped member 12 switches from the working state to the moving state. The electric push rod is a linear driving member, and its rotatable connection with the second arc-shaped member 12 enables it to cooperate with the rotation of the second arc-shaped member 12.

[0074] Optionally, referring to Figure 1 and Figure 2, The auxiliary tooling for the joint filling operation further includes a traveling assembly 4. The traveling assembly 4 is arranged on the bracket 1 so that the bracket 1 can move along the axial direction of the pipeline 100.

[0075] Exemplarily, the traveling assembly 4 includes a plurality of traveling wheels. The traveling wheels are arranged on the top of the first arc-shaped member 11 and are rotationally engaged with the pipe wall of the pipeline 100. When the traveling wheels rotate, the movement of the bracket 1 on the pipeline 100 can be realized.

[0076] Further, the traveling assembly 4 further includes a braking member arranged on the traveling wheels. After the auxiliary tooling moves to a predetermined position on the pipeline 100, the traveling wheels can be braked by the braking member, so that the auxiliary tooling remains stationary at the predetermined position; when it is necessary to move the auxiliary tooling, only need to relax the braking member to make the traveling wheels return to the rotatable state.

[0077] Specifically, the process of installing the auxiliary tooling for the joint filling operation provided in this embodiment on the pipeline 100 is as follows: drive the bracket 1 to move until the bracket 1 moves to the position to be joint-filled, and the traveling wheels stop rotating; then, use the third driving member 16 to switch the second arc-shaped member 12 from the moving state to the working state, and use the locking assembly 3 to limit the second arc-shaped member 12 in the working state. At this time, the first clamping member 121 is in contact with the outer wall of the pipeline 100; next, use the second driving member 112 to drive the second clamping member 111 to move so that the second clamping member 111 is in contact with the outer wall of the pipeline 100. During the movement of the second clamping member 111, the distance between the traveling wheels and the pipeline 100 gradually increases, and the traveling wheels are separated from the outer wall of the pipeline 100 to avoid the traveling wheels affecting the movement of the functional module.

[0078] When the functional module completes the operation and it is necessary to move the bracket 1, just operate in the reverse order of the above steps, which will not be elaborated here.

[0079] Optionally, refer to Figure 2 and Figure 7 , A plurality of groups of brackets 1 are provided. The plurality of groups of brackets 1 are arranged at intervals along the axial direction of the pipeline 100. The auxiliary tooling for the joint filling operation further includes a plurality of connecting rods 5. The arc-shaped connecting members 221 on any two adjacent groups of brackets 1 are connected by the connecting rods 5. The functional module is connected to the arc-shaped connecting member 221 through the connecting rod 5. On the one hand, the connecting rod 5 can increase the integrity and stiffness of the plurality of arc-shaped connecting members 221 on two adjacent groups of brackets 1 and ensure the overall stability of the auxiliary tooling for the joint filling operation; on the other hand, it can provide space for the installation of the functional module on the arc-shaped connecting member 221 to ensure that the functional module can be stably installed on the bracket 1.

[0080] In this embodiment, there are two sets of brackets 1, and the functional module is located between the two sets of brackets 1 and is installed on the connecting rod 5. When the first driving member 21 drives the arc-shaped connecting member 221 to move, the arc-shaped connecting member 221 drives the functional module to move through the connecting rod 5.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
