Description

Technical Field

[0001] The invention relates to the field of steel pipe (or steel lining) manufacturing and installation, and in particular to a tile assembly welding device and a tile assembly method. Background Art

[0002] In projects such as water conservancy and hydropower or compressed gas energy storage, large-diameter steel pipes (5 meters and above) are generally made by welding multiple tiles together. When the tiles are assembled, it is mainly necessary to weld the longitudinal butt welds between the tiles. Generally, during on-site construction, in order to facilitate operations such as tile assembly and butt weld welding, the steel pipe assembly welding device disclosed in the Chinese invention patent with the authorization announcement number CN104308413B is often used to assist in the construction of tile assembly welding. After the tiles are fixed on the multiple top beams of the rotating support frame of the steel pipe assembly welding device in sequence with clamps and bolts, the automatic welding equipment is used to automatically weld the tile butt welds.

[0003] During the butt weld construction, in order to facilitate welding, the butt welds between tiles need to be staggered from the top beam position, so the butt welds between tiles are often in a suspended state, which makes it difficult to align and adjust the welds.

[0004] In order to facilitate the starting and ending of the weld, it is necessary to weld arc-starting plates at the front and rear ends of the weld to start and end the arc during welding to ensure the welding quality. However, the butt welds between tiles are often in a suspended state, so the arc-starting plates can only be welded to the ends of the tiles. After the welding is completed, the arc-starting plates are cut and removed from the tiles, and the cutting and removal process is rather cumbersome.

[0005] In addition, in order to facilitate the penetration of the joint root of the weld and the formation of the back of the weld, a welding ceramic liner is generally pasted on the back of the entire weld during welding to ensure the welding quality of the weld. The butt weld between tiles needs to be formed after the two adjacent tiles are installed and determined, so it is necessary to paste the welding ceramic liner after the butt weld is formed. However, the butt weld between tiles is often in a suspended state, so pasting the welding ceramic liner is time-consuming and laborious.

[0006] When the tiles are fixed to the swivel support frame of the steel pipe welding device, they are generally fixed to the top beam of the swivel support frame by U-shaped claws, which is basically a manual operation and is time-consuming and labor-intensive. This method is to clamp and fix the tiles by bolting. Since the bolt preload is often large, it sometimes causes the top beam to bend or deform the entire swivel support frame during actual construction. If the swivel support frame or the top beam is strengthened as a whole, the weight of the entire swivel support frame will increase, bringing a greater overturning moment, and is not conducive to the lightweight of the entire equipment; and if the bolt preload of the U-shaped claw is reduced, it will lead to loose fixation, which poses a safety risk.

[0007] The above work is generally carried out by fixing the first tile on the rotating support frame of the steel pipe welding device, and then fixing and aligning the second tile with the rotating support frame of the steel pipe welding device to form a butt weld, and then welding arc-starting plates at the front and rear ends of the butt weld, and then pasting a welding ceramic pad on the back of the entire weld; then installing the third tile and aligning it with the second tile, and then welding the arc-starting plate and pasting the welding ceramic pad at the butt weld between the third tile and the second tile, repeating until the circle is formed, and then welding the butt welds one by one after the circle is formed. Because the above steps need to be completed step by step and cannot be carried out at the same time, it takes a long time to complete the above preparation work, which in turn increases the construction time of the entire construction and reduces the construction efficiency. Summary of the invention

[0008] The purpose of the present invention is to provide a tile assembly welding device and a tile assembly method to address the shortcomings that "when the steel pipe assembly welding device in the prior art performs auxiliary construction of tile assembly welding, the butt welds between tiles are often in a suspended state, which makes it difficult to align and align the welds, which in turn makes the construction more difficult and the construction time of the entire construction longer."

[0009] In a first aspect, the present invention provides a tile assembly circular welding device, comprising a main body rotating shaft and a rotary support frame, wherein the rotary support frame comprises:

[0010] Radial supports, at least four of which are distributed circumferentially and spaced apart along the main body rotating shaft, wherein the radial supports include telescopic adjustment struts, which are arranged radially along the slewing support frame, and the telescopic adjustment struts can adjust their lengths along the radial direction of the slewing support frame;

[0011] A main top beam, each of which is arranged at the end of the corresponding telescopic adjustment strut, and the main top beam comprises a first beam body and a first fixing member; the length direction of the first beam body is arranged along the axial direction of the slewing support frame, the width direction of the first beam body is arranged along the tangent direction of the slewing support frame, and the first beam body is fixedly connected to the end of the telescopic adjustment strut; the side of the first beam body away from the radial support is the working surface, the first fixing member is arranged on the side where the working surface of the first beam body is located, and the first fixing members are respectively arranged on both sides of the width direction of the first beam body;

[0013] Compared with the prior art, the tile assembly welding device of the present invention is provided with a main top beam and a secondary top beam at the same time. The secondary top beam is located between two adjacent main top beams, and its main function is to assist in the adjustment of the roundness of the pipe section, so as to provide stable welding conditions for the main top beam to be arranged at the weld. Compared with the conventional top beam, the main top beam can be used as a structure fixed to the tile through the first fixing part, so that the main top beam can be supported at the weld of two adjacent tiles, so that when the tiles are installed for assembly, the main top beam is used as the basis, so that the butt welds between the tiles are no longer in a suspended state, so that the alignment and correction of the welds are simpler. By supporting the welds of two adjacent tiles with the main top beam, the assembly construction of the tiles can be simpler, and the construction efficiency can be improved, and the assembly period can be shortened.

[0014] Preferably, the main top beam further includes a welding pad, and the welding pad is arranged on the side where the working surface of the first beam body is located, and the welding pad is arranged along the length direction of the first beam body.

[0015] The welding pad is set on the main top beam in advance, and there is no need to stick the welding pad after the weld is formed. The operation is simpler and the welding pad can be aligned with the butt weld of the tile when the first beam supports the butt weld of the tile, making the installation more convenient and accurate, and avoiding the time-consuming and laborious hanging sticking at the butt weld on site.

[0016] Preferably, the main top beam further comprises an arc-starting plate and an arc-ending plate, both of which are arranged on the side where the working surface of the first beam body is located; the arc-starting plate and the arc-ending plate are respectively arranged at both ends of the first beam body; the arc-starting plate and the arc-ending plate are both arranged above the welding pad along the width direction of the first beam body;

[0017] In the width direction of the first beam body, grooves are provided in the middle of the arc-starting plate and the arc-closing plate. The grooves of the arc-starting plate are used for arc starting, and the grooves of the arc-closing plate are used for arc closing.

[0018] The arc-starting plate and the arc-ending plate are arranged on the main top beam.

[0023] The tile ends can be inserted into the set gap, so that the tiles can be initially fixed, and then the tiles are welded to the first fixing member through the welding surface, and then fixed to the first beam body, effectively solving the potential safety hazard of sliding of the tiles during rotation. The first fixing members are respectively arranged on both sides of the width direction at both ends of the length direction of the first beam body, so as to avoid the first fixing member occupying too large an area, making it easier for the tile ends to be inserted into the set gap, and saving material costs.

[0030] When the extrusion structure is a high temperature resistant air cushion, the high temperature resistant air cushion is inflated through the inflation port to squeeze the welding pad toward the tile weld, and air can be replenished in real time so that the welding pad is always in close contact with the back of the weld.

[0031] Preferably, the mounting structure is a gasket mounting box;

[0032] In the width direction of the first beam body, the width of the through groove is greater than the width of the gasket installation box.

[0033] The gasket installation box has a better protective effect on the welding gasket, and the width of the through slot is greater than the width of the gasket installation box, which is more conducive to replacing the welding gasket.

[0034] Preferably, there is at least one main top beam along the main body rotation axis and further includes a positioning member or a positioning mark.

[0037] Preferably, second fixing members are provided at both ends of the second beam body, and the second fixing members can realize auxiliary fixing of the tiles.

[0041] The first strong magnet is arranged inside the second beam body, and magnetic isolation material pieces are arranged around the first strong magnet in the length direction and the width direction of the second beam body, and magnetic isolation material pieces are arranged on the side of the first strong magnet radially close to the radial support with respect to the rotating support frame, and a magnetic isolation plate is arranged on the side of the first strong magnet radially away from the radial support with respect to the rotating support frame, and a sliding groove is arranged on the side of the second beam body radially away from the radial support with respect to the rotating support frame, and the magnetic isolation plate is slidably arranged in the sliding groove, and the magnetic isolation plate can slide in the sliding groove to expose or close the first strong magnet;

[0042] The second strong magnet is arranged inside the second beam body, and magnetic isolation material pieces are provided around the second strong magnet in the length direction and the width direction of the second beam body.

[0043] The above fixing method can save manual operation time and optimize the construction period.

[0044] Preferably, the main top beam is arranged at the end weld of the tile, and the first beam body is located on the inner side of the corresponding tile, which is suitable for the construction where the tile has only a single-sided groove on the outer side.

[0045] Preferably, the radial support is evenly distributed circumferentially along the main body rotation axis, the main top beam is evenly distributed circumferentially along the rotating support frame, and all the second beams are evenly arranged between the circumferentially adjacent first beams, so that the force is evenly applied during rotational welding, which can better ensure the welding quality.

[0046] In a second aspect, the present invention provides a tile assembly method, which uses the tile assembly welding device to assemble tiles with grooves on the outer sides of the ends, comprising the following steps:

[0048] S2: installing the remaining tiles one by one along the circumferential direction of the rotary support frame until the circle is completed;

[0049] The remaining steps for installing each tile are:

[0050] The main body rotating shaft controls the rotation of the slewing support frame to drive the previously installed tile to move upward, so that the two main top beams adjacent to one end of the previously installed tile are located at the lower part of the slewing support frame, and the tile to be currently installed is transported to the bottom of the slewing support frame; then the tile to be currently installed is lifted so that the inner sides of the two ends of the tile are close to the corresponding first beam body, and then the tile to be installed is adjusted with the corresponding end of the previously installed tile as the positioning, so that the end of the tile to be currently installed is located at the corresponding side of the working surface of the corresponding first beam body in the slewing support frame; then the end of the tile to be currently installed is fixed to the two adjacent main top beams through the corresponding first fixing member, and then the tile to be currently installed is supported by the secondary top beam corresponding to the tile to be currently installed.

[0051] The above-mentioned tile rounding method can use the main top beam with positioning parts or positioning marks as the basis for positioning, thereby ensuring the accuracy of the tile installation position, facilitating tile positioning, and saving adjustment time during tile installation; at the same time, based on the main top beam, the butt welds between tiles are no longer in a suspended state, thereby making the alignment and correction of the welds simpler and saving construction time; and after the tiles are positioned and fixed by the main top beam, the tiles are supported by the secondary top beam for auxiliary rounding, thereby reducing the impact of welding deformation and ensuring the welding quality and stability of the welding process.

[0081] Example 1

[0082] like Figure 1-7 As shown, a tile assembly circular welding device includes a main body rotating shaft 66 and a rotary support frame 65, wherein the rotary support frame 65 includes a radial support, a main top beam 1 and a secondary top beam 3;

[0083] At least four radial supports are distributed circumferentially and spaced apart along the main body rotation axis 66; Figure 1 and Figure 2 As shown, the radial support includes a telescopic adjustment strut 4, which is arranged radially along the slewing support frame 65, and the telescopic adjustment strut 4 can adjust its length along the radial direction of the slewing support frame 65. Figure 1 and Figure 4 As shown, the telescopic adjustment strut 4 is a hydraulic strut, and the radial support includes two hydraulic struts, which can be axially telescopic, and the two hydraulic struts are axially spaced apart on the main body shaft 66, and the two hydraulic struts are connected to form a whole through an axial cross-link rod 41. Figure 1 As shown, adjacent hydraulic struts are connected to form a whole through an annular cross-link rod 651 to ensure the support stability of the entire slewing support frame 65. In addition to the hydraulic strut, the telescopic adjustment strut 4 can also be adjusted by screw, electric and pneumatic means.

[0084] like Figure 1-Figure 6 As shown, the main top beam 1 is arranged at the end corresponding to the telescopic adjustment strut 4, and the radial position of the main top beam 1 can be adjusted by the telescopic adjustment strut 4; the main top beam 1 includes a first beam body 11, an arc-starting plate 121, an arc-closing plate 122, a first fixing member 13 and a welding pad 14; the welding pad 14 can be a ceramic component or a copper component. Among them, the arrangement of the arc-starting plate 121, the arc-closing plate 122 and the welding pad 14 is optional, which is a better solution.

[0085] The length direction of the first beam body 11 is axially arranged along the rotating support frame 65, and the width direction of the first beam body 11 is arranged along the tangent direction of the rotating support frame 65. The first beam body 11 is fixedly connected to the end of the telescopic adjustment strut 4; the first beam body 11 and the second beam body are made of welded steel plates, profiles, etc.

[0086] As a preferred option, there is at least one main top beam 1 circumferentially along the main body rotation axis 66 and further includes a positioning member 15 or a positioning mark, and positioning can be performed by the positioning member 15 or the positioning mark.

[0087] by Figure 8 For example, there are three radial support ends with a main top beam 1, the three radial supports correspond to the trisection lines of the circumference, and the main top beam 1 on one or both sides of the upper left and right has a positioning piece 15, and the main top beam 1 at the bottom is not provided with a positioning piece 15, so the main top beams 1 on the upper left and right sides are used as the installation positioning and fixing structure of the first tile.

[0088] The side of the first beam body 11 away from the radial support is a working surface, that is, Figure 5 The upper side of the first beam body 11 is the working surface. The arc-starting plate 121, the arc-ending plate 122, the first fixing member 13, the welding pad 14 and the positioning member 15 are all arranged on the side where the working surface of the first beam body 11 is located.

[0089] like Figure 5As shown, the arc-starting plate 121 and the arc-closing plate 122 are respectively arranged at both ends of the first beam body 11; in the width direction of the first beam body 11, the middle parts of the arc-starting plate 121 and the arc-closing plate 122 are both provided with grooves, such as Fig. 9 As shown, the groove of the arc-starting plate 121 is used for arc-starting, and the groove of the arc-closing plate 122 is used for arc-closing. The grooves correspond to the grooves at the ends of the tiles, and arc-starting and arc-closing can be achieved. The grooves of the arc-starting plate 121 and the arc-closing plate 122 are both adapted to the grooves of the butt welds of the tiles 5. For example, the grooves of the arc-starting plate 121 and the arc-closing plate 122 are V-shaped. When two adjacent tiles are installed, the butt weld formed between the two adjacent tiles is also V-shaped, and the V-shaped groove faces the outside of the tile. During welding, the length of the arc-starting is greater than the length of the arc-closing. In the length direction of the first beam 11, as shown in FIG. Figure 5 As shown, the length of the arc-starting plate 121 is greater than the length of the arc-ending plate 122 , and the length of the groove of the arc-starting plate 121 is greater than the length of the groove of the arc-ending plate 122 , which can ensure welding requirements, reduce waste, and save costs.

[0090] like Figure 4-Figure 7 As shown, the welding pad 14 is arranged along the length direction of the first beam body 11, and the arc-starting plate 121 and the arc-closing plate 122 are both arranged above the welding pad 14 along the width direction of the first beam body 11; in a preferred embodiment, the welding pad 14 is arranged along the length direction of the first beam body 11, which is conducive to the welding of the tile weld, the arc-starting plate 121 and the arc-closing plate 122 at the same time. Figure 4-Figure 7 As shown, a through groove 143 is provided on the side where the working surface of the first beam body 11 is located, and an extrusion structure is provided at the bottom of the through groove 143. A mounting structure is provided on the extrusion structure, and the welding pad 14 is arranged on the mounting structure. The mounting structure can provide protection for the extrusion structure and the welding pad 14, and the mounting structure can be a steel plate. The extrusion structure squeezes the welding pad 14 toward the tile weld through the mounting structure, so that the welding pad is close to the back of the weld, thereby ensuring the welding quality and preventing the ceramic pad from being burned through or falling off. Among them, the extrusion structure is an elastic structure or a high-temperature resistant air cushion 142. When the extrusion structure is an elastic structure, such as a spring arranged between the bottom of the through groove 143 and the mounting structure, the spring is continuously arranged along the length direction of the welding pad. When the extrusion structure is a high-temperature resistant air cushion 142, such as Figure 7 and Fig. 9 As shown, the extrusion structure is provided with an air filling port at one end along the length direction of the first beam body 11, and the air filling port extends out from the corresponding end of the first beam body 11. When the extrusion structure is a high temperature resistant air cushion 142, the high temperature resistant air cushion 142 is inflated through the air filling port so that the welding pad 14 is squeezed toward the tile weld, and air can be replenished in real time so that the welding pad is always close to the back of the weld. Figure 7 As shown, the installation structure is a gasket installation box 141, and the gasket installation box 141 has a better protection effect on the welding gasket 14; in the width direction of the first beam body 11, the width of the through groove 143 is greater than the width of the gasket installation box 141, which is more conducive to replacing the welding gasket 14. The welding gasket 14 will be replaced after welding. The width of the through groove 143 is greater than the width of the gasket installation box 141, so that the through groove 143 and the gasket installation box 141 are fixed by filling. After welding, the gasket installation box 141 is taken out together with the welding gasket 14 for replacement.

[0091] like Figure 4 and Figure 6 As shown, the first fixing members 13 are respectively arranged on both sides of the width direction at both ends of the length direction of the first beam body 11; there is a setting gap between the first fixing member 13 and the first beam body 11, and the setting gap is used to adapt to the setting of the end of the tile 5, and the first fixing member 13 along the radial direction of the slewing support frame 65 facing the first beam body 11 is a welding surface, and the welding surface is used to be welded and fixed to the outer surface of the tile 5. The end of the tile 5 can extend into the setting gap, such as Fig. 9 As shown, the tile 5 can be initially fixed, and then the tile 5 is welded to the first fixing member 13 through the welding surface, and then fixed to the first beam body 11, which effectively solves the potential safety hazard of sliding of the tile during rotation. The first fixing member 13 can be a fixing plate, channel steel, angle steel or rectangular tube, etc. Figure 4 As shown, the first fixing member 13 is detachably connected to the arc-starting plate 121 or the arc-closing plate 122 at the corresponding end on one side of the width direction of the first beam body 11, and the arc-starting plate 121 and the arc-closing plate 122 are detachably connected to the first beam body 11. It is convenient to install the adjacent ends of two adjacent tiles. Figure 4 As shown, the fixing plate, the arc-starting plate 121 or the arc-ending plate 122 and the first beam 11 are fixedly connected by means of bolts. The arc-starting plate or the arc-ending plate 122 can be installed in advance when the tiles are installed and fixed, eliminating the subsequent process of separately installing and welding the arc-starting plate, thereby optimizing the construction time and process.

[0092] like Figure 4 As shown, the positioning member 15 is arranged on one side of the tangent direction of the first beam 11 corresponding to the first beam body 11 of the slewing support frame 65. The positioning member 15 has a positioning straight edge on the side close to the welding pad 14, which can ensure the accurate positioning of the tile end face. The positioning member 15 is used to position the edge of the tile end, and can be a positioning plate, a profile with a straight edge, or a round bar, etc.

[0093] In this embodiment, the auxiliary top beam 3 is arranged between two circumferentially adjacent main top beams 1, and its main function is to assist fixation and assist adjustment of the roundness of the pipe section. For example, if there are four radial supports in total, the main top beams 1 are arranged at the ends of two radial supports, and the auxiliary top beams 3 are arranged at the ends of the remaining two radial supports, and the main top beams 1 and the auxiliary top beams 3 are staggered in the circumferential direction. If there are three main top beams 1, one, two, three or more auxiliary top beams 3 can be evenly arranged between two adjacent main top beams 1, and the number of main top beams 1 is equal to the number of tiles in the circumferential direction, while the number of auxiliary top beams 3 is related to the size of the tiles.

[0094] Among them, the auxiliary top beam 3 can adopt the structural form of a conventional top beam. The auxiliary top beam 3 includes a second beam body and a second fixing part, and the second beam body is made of welded steel plates, profiles, etc. The second beam body is connected to the end of the radial support, and the radial position of the main top beam 1 can be adjusted by hydraulic struts to achieve support; the length direction of the second beam body is axially arranged along the rotating support frame 65, and the width direction of the second beam body is arranged along the tangent direction of the rotating support frame 65. All the second beam bodies are evenly arranged between the circumferentially adjacent first beam bodies 11, and the second fixing parts are provided at both ends of the second beam body. The second fixing part adopts a clamp, a strong magnet or an electromagnet.

[0095] like Figure 10-12 As shown, when the second fixing member adopts a clamp, the second beam body is the first supporting beam body 311; the second fixing member includes a clamp hydraulic cylinder 312 and a fixing clamp 313, the clamp hydraulic cylinder 312 is arranged along the length direction of the second beam body, and the fixing clamp 313 is arranged at the end of the second beam body; in the radial direction of the rotary support frame 65, a setting gap is formed between the fixing clamp 313 and the second beam body, and the setting gap is used to adapt to the setting of the end of the tile 5; the clamp hydraulic cylinder 312 can drive the fixing clamp 313 to move along the length direction of the second beam body. Fig.11 As shown, when the auxiliary top beam is used to assist in fixing the tile, the clamp hydraulic cylinder 312 is used to first drive the fixing clamp 313 to move along the length direction of the second beam body to open at both ends, and then the hydraulic strut is extended to make the second beam body close to the tile, and then the clamp hydraulic cylinder 312 is used to drive the fixing clamp 313 to move along the length direction of the second beam body to move closer to the middle, so that the tile enters the gap between the fixing clamp 313 and the second beam body to form a clamping fixation. When the hydraulic clamp is used for fixing, the fixing clamp is driven by the hydraulic cylinder to clamp and fix the tile on the auxiliary top beam. Except, as Fig.10 As shown, a sliding groove 314 may be provided on the upper surface of the first supporting beam 311, and a clamp may be provided to slide and be fixed in the length direction of the sliding groove 314, so as to adapt to the clamping of tiles of different widths.

[0096] like Figure 13-Figure 15 When the second fixing member adopts a strong magnet, optionally, the second beam body is a second supporting beam body 321; the second fixing member includes a first strong magnet 323, the first strong magnet 323 is arranged inside the second beam body, and magnetic isolation material pieces 322 are arranged around the first strong magnet 323 in the length direction and the width direction of the second beam body, and a magnetic isolation material piece 322 is arranged on the side of the first strong magnet 323 radially close to the radial support with respect to the rotating support frame 65, and a magnetic isolation plate 324 is arranged on the side of the first strong magnet 323 radially away from the radial support with respect to the rotating support frame 65, and a slide groove 326 is arranged on the side of the second beam body radially away from the radial support with respect to the rotating support frame 65, and the magnetic isolation plate 324 is slidably arranged in the slide groove 326, and the magnetic isolation plate 324 can slide in the slide groove 326 to expose or close the first strong magnet 323. When the first strong magnet 323 is used, a magnetic isolation plate 324 is made of magnetic isolation material and magnetic conductive material, each of which is half magnetic isolation material and half magnetic conductive material. The magnetic isolation plate can be dragged in the slide groove 326. When the magnetic isolation material of the magnetic isolation plate covers the first strong magnet 323, the magnetic force is isolated, so that the auxiliary top beam is detached from the tile. When the magnetic conductive material of the magnetic isolation plate covers the first strong magnet 323, the magnetic force is restored, so that the auxiliary top beam is fixed to the tile. By setting the length and position of the magnetic isolation material and the magnetic conductive material of the magnetic isolation plate 324 in the length direction of the second beam body, it can adapt to the fixation of tiles of different widths. After the tile is fixed by the main top beam 1, the magnetic force is isolated by covering the first strong magnet 323 with the magnetic isolation material of the magnetic isolation plate, and then the second support beam 321 is made close to the tile by extending the hydraulic strut, and then the magnetic isolation plate is dragged in the slide groove 326, so that the magnetic conductive material of the magnetic isolation plate covers the first strong magnet 323, so that the second support beam 321 is fixed to the tile by magnetic attraction.

[0097] like Figure 16-18When the second fixing member adopts a strong magnet, the second beam body is a third supporting beam body 331. Optionally, the second fixing member includes a second strong magnet 333, and the second strong magnet 333 is arranged inside the second beam body. Magnetic isolation material pieces 322 are arranged around the second strong magnet 333 in the length direction and the width direction of the second beam body. The second strong magnet 333 is connected to a magnet hydraulic cylinder 332, and the magnet hydraulic cylinder 332 is axially arranged along the radial direction of the rotating support frame 65. The magnet hydraulic cylinder 332 is arranged on the side of the second beam body close to the radial support, and the magnet hydraulic cylinder 332 can drive the second strong magnet 333 to move radially along the rotating support frame 65. When in use, after the tile is fixed by the main top beam 1, the second strong magnet 333 is pulled back by the magnet hydraulic cylinder 332, so that the second strong magnet 333 is not on the working surface, and the second strong magnet 333 does not generate magnetic force with the tile or generates a small magnetic force, and then the hydraulic strut is extended to make the third support beam 331 close to the tile, and then the axis of the magnet hydraulic cylinder 332 is extended to make the second strong magnet 333 adsorbed on the tile, so that the third support beam 331 is fixed to the tile.

[0098] like Figure 1 As shown, the tile group circle welding device includes a column 61, a crossbeam 62, a main body 64, and a swivel support frame 65. The crossbeam 62 is arranged above the column 61, the main body 64 is arranged above the crossbeam 62, the main body 64 has a main body rotation shaft 66, and the swivel support frame 65 is arranged on the main body rotation shaft 66. The main body rotation shaft 66 is arranged horizontally and can drive the swivel support frame 65 to rotate. The swivel support frame 65 includes a sub-top beam 3 and a hydraulic support rod. Compared with the prior art, this embodiment provides the tile group circle welding device, such as Figure 1-Figure 18As shown, it also includes a main top beam 1, which includes a first beam body 11. The first beam body 11 is also provided with an arc-starting plate, a positioning plate, a fixing plate, a welding pad and a high-temperature resistant air cushion or spring. The first beam body 11 is made of welded steel plates, profiles, etc., and has multiple sets of fixing holes reserved thereon, which can fix the arc-starting plate and the positioning plate. The first beam body 11 also has a connecting hole connected and fixed to the hydraulic strut, and a through groove for the welding pad is reserved in the middle of the top, so that the welding pad can be installed on the first beam body in advance. The arc-starting plate is used for arc starting and arc ending during welding, and is mainly made of steel plates, and has fixing holes thereon, and can be fixed on the first beam body. The arc-starting plate has a groove in the middle that is the same as the tile butt weld. The positioning plate is used for positioning and limiting when installing tiles, and is mainly made of steel plates, and has fixing holes thereon, which can be fixed on the first beam body. The fixing plate is mainly used for fixing tiles. It is mainly made of steel plate. A fixing hole is left on one side of it, which can be fixed to the first beam body, and the other side can be fixed to the tile by welding. The fixing plate can fix the tile on the multiple main top beams contained in the rotating support frame of the steel pipe group circular welding device, and can prevent the tile from sliding during the construction rotation process. The fixing plate can be cut and removed after the last pipe section construction is completed. The welding pad is generally placed on the back of the groove of the required welding weld. By welding from the front, both sides can be formed at one time. The back weld is full, the weld mark is neat, and the shape is beautiful. The welding ceramic pad is installed in the pad installation box in advance, and then the pad installation box is installed in the through groove of the first beam body. There is a spring or a high-temperature resistant air cushion between the pad installation box and the through groove, which can make the welding pad close to the back of the tile weld. The high-temperature resistant air cushion is made of high-temperature resistant flexible material, and the internal inflatable gas can expand itself. The main function is to provide a top tightening force so that the welding pad can be close to the back of the weld. Another way is to install springs in the through slots of the main top beam in advance, and use the springs to provide preload to make the welding pad close to the back of the weld. Multiple sets of springs are fixed to the bottom of the through slots in advance, and the elastic force of the springs can make the welding pad close to the back of the weld. The hydraulic strut is mainly composed of a hydraulic cylinder and an extension section, which is used to connect and fix the entire main top beam and the auxiliary top beam. The other end is connected and fixed to the main body shaft part of the steel pipe assembly welding device through a flange. The hydraulic strut can extend or retract the main top beam and the auxiliary top beam through hydraulic drive, so as to adjust the size of the assembly radius, or adjust the roundness of the tiles when they are assembled into pipe sections. The extension section at the end of the hydraulic strut can be combined according to construction needs to obtain the required assembly size.

[0099] The tile group circular welding device provided in this embodiment can effectively optimize the overall construction process. In the existing technical solution, each top beam needs to be fixed manually using a clamp. After optimization, the top beam is divided into two types: a main top beam and a secondary top beam. The secondary top beam is changed to an automatic fixing method such as magnetic force and hydraulic pressure, so there is no need for manual fixing, which can save manual operation time and optimize the construction period. The installation position of the arc-starting plate is set on the main top beam, and the fixing method of the tile is changed from clamp pressing and fixing to fixed plate welding and fixing. The arc-starting plate can be installed in advance when the tile is installed and fixed, eliminating the subsequent process of separately installing and welding the arc-starting plate, optimizing the construction time and process. The arc-starting plate is not welded and fixed to the tile, and it is more convenient to cut and remove. After the tile is fixed by welding the fixed plate, the safety hazard that the tile may slide during the rotation process is effectively solved, and the other end of the fixed plate is fixed to the first beam body by bolts, which is convenient for disassembly and assembly. The reserved through grooves on the main roof beam can be used to install welding pads in advance, which can optimize the welding pad installation process and effectively save construction time. The bottom can make the welding pad close to the back of the weld through the air cushion, spring, etc., so as to ensure the welding quality and prevent the welding ceramic pad from being burned through or falling off. The positioning plate set on the main roof beam serves as the positioning reference of the tile during installation, which facilitates the positioning of the tile and saves the adjustment time during tile installation. At the same time, the butt welds between the tiles are adjusted from the suspended state to the main roof beam, which can facilitate the adjustment of the tile butt welds, so that the main roof beam can be used as the back support when the tile is adjusted.

[0100] Example 2

[0101] A tile assembly method, using the tile assembly welding device described in Example 1 to assemble tiles 5 having grooves on the outer sides of the ends, comprises the following steps:

[0102] S1: transport the first tile 5 to the bottom of the slewing support frame 65, and control the main top beam 1 with the positioning piece 15 or the positioning mark and the adjacent main top beam 1 to be located at the bottom of the slewing support frame 65 through the main body rotating shaft 66; then lift the first tile 5 so that the tile 5 is closely attached to the first beam body 11 of the main top beam 1 with the positioning piece 15 or the positioning mark and the adjacent main top beam 1 to the inner side of both ends; then adjust the end of the first tile 5 by the positioning piece 15 or the positioning mark so that the end of the first tile 5 is located at the working position of the first beam body 11 The first beam 11 is provided with a welding pad 14 on one side of the circumferential direction of the swivel support frame 65 (when the working surface of the first beam body 11 is provided with a welding pad 14, the end of the first tile 5 is located on the side of the welding pad 14 on the circumferential direction of the swivel support frame 65), and then the end of the first tile 5 is fixed to the two adjacent main top beams 1 through the corresponding first fixing member 13; then after the first tile 5 is positioned and installed through the two adjacent main top beams 1, the auxiliary top beam 3 between the main top beams 1 at both ends of the first tile 5 is used to realize auxiliary support for the first tile 5, and it can also be fixedly connected through the second fixing member for auxiliary fixation;

[0103] S2: installing the remaining tiles 5 one by one along the circumferential direction of the rotary support frame 65 until the circle is completed;

[0104] The remaining steps for installing each tile 5 are:

[0105] The rotating support frame 65 is controlled to rotate by the main body rotating shaft 66 to drive the previously installed tile 5 to move up, so that the two main top beams 1 adjacent to one end of the previously installed tile 5 are located at the lower part of the rotating support frame 65, and the tile 5 to be installed is transported to the bottom of the rotating support frame 65; then the tile 5 to be installed is lifted so that the inner sides of the two ends of the tile 5 are close to the corresponding first beam body 11, and then the tile 5 to be installed is adjusted with the corresponding end of the previously installed tile 5 as the positioning, so that the end of the tile 5 to be installed is located at the opposite The working surface of the first beam body 11 should be on the corresponding side of the circumferential direction of the rotating support frame 65 (when the working surface of the first beam body 11 is provided with a welding pad 14, the end of the tile 5 to be installed is located on the side of the welding pad 14 on the circumferential direction of the rotating support frame 65); then the end of the tile 5 to be installed is fixed to the two adjacent main top beams 1 through the corresponding first fixing member 13, and then the tile 5 to be installed is supported by the secondary top beam 3 corresponding to the tile 5 to be installed; it can also be fixedly connected by a second fixing member for auxiliary fixation.

[0106] The following is a specific example of the above tile circle grouping method:

[0107] Install the welding gasket in the gasket installation box of the main top beam, and then install the gasket installation box in the through slot on the top of the main top beam. There can be multiple gasket installation boxes, and finally multiple gasket installation boxes are combined into a whole and placed in the through slot for use. A whole high-temperature resistant air cushion needs to be arranged between the gasket installation box and the through slot to lift the welding gasket and press it against the back of the weld during subsequent welding construction, or a spring can be arranged between the gasket installation box and the through slot in advance to use the spring force to tighten the gasket.

[0108] Multiple sets of main top beams, auxiliary top beams and hydraulic support rods are assembled together in a circumferentially uniform manner to form a swivel support frame of the steel pipe group circular welding device, and the swivel support frame is fixedly connected to the swivel shaft of the steel pipe group circular welding device, such as Figure 1As shown. The main top beam and the auxiliary top beam are part of the slewing support frame. They need to be assembled on the hydraulic struts before use. The main top beams are first installed evenly along the circumference. For example, 3 groups of main top beams are evenly distributed along the circumference at 120°, and 4 groups of main top beams are evenly distributed along the circumference at 90°. After the installation is completed, the auxiliary top beams are installed on the hydraulic struts between the main top beams and evenly distributed. Install the positioning plate on the top of one of the main top beams in advance as the positioning reference when installing the first tile. It can also prevent the tile from sliding during the rotation process due to loose fixation. The main top beam is the main fixing point. The hydraulic struts of the main top beam need to be adjusted first so that the multiple groups of main top beams in the whole circle are in the required construction size position. The auxiliary top beam is used as an auxiliary fixation and can be appropriately adjusted later during the installation process.

[0109] Taking the example of three tiles assembled into a pipe section, the single tile of the pipe section is transported to the bottom of the steel pipe assembly welding device by multi-functional trolleys and other equipment. After adjusting the approximate installation position, the first tile is lifted and pressed against the first beam of the main top beam of the steel pipe assembly welding device with the help of the trolley. Then, fine-tuning is performed to adjust the installation position of the first tile on the main top beam so that the edge of one end of the first tile is pressed against the positioning plate on the main top beam. Use bolts to install two sets of arc-starting plates and fixed plates to both ends of the main top beam on both sides of the first tile. The arc-starting plate is located below the fixed plate and pressed against the side of the first tile. The fixed plate is located on the arc-starting plate and the first tile. One end is fixed to the arc-starting plate and the first beam of the main top beam by bolts, and the other end is fixed to the outer arc surface of the first tile by welding. Fig. 9 After the installation and fixation is completed, the hydraulic support rod is adjusted to extend the second beam body of the auxiliary top beam corresponding to the first tile to be close to the inner arc surface of the first tile, and the first tile is attracted by the magnet or magnetic device arranged thereon to provide auxiliary fixation.

[0110] After the first tile is installed and fixed, the swivel support frame 65 of the steel pipe group circular welding device is rotated 120° as a whole. The second tile is transported to the bottom of the steel pipe group circular welding device in the same way, and the first beam body working surface close to the main top beam of the steel pipe group circular welding device is lifted, and the first tile is used as the installation and positioning reference of the second tile. When the second tile is installed, the position is adjusted so that its end face is close to the first tile, and the two tiles are aligned. One side shares a main top beam with the first tile when fixed. A set of fixing plates are fixed to the arc-starting plate at one end of the first tile and the first beam body of the main top beam, and are fixed with the outer arc of the second tile. The other end of the second tile is also fixed to the first beam body of the main top beam using a set of arc-starting plates and fixing plates. After fixing, the hydraulic support rod is extended so that the second beam body of the secondary top beam in the corresponding range of the second tile is close to the inner arc surface of the second tile, and the second tile is attracted by the magnet or magnetic device arranged thereon to provide the purpose of auxiliary fixing.

[0111] Then rotate the swivel support frame 65 of the steel pipe group circular welding device 120° to prepare for the installation of the third tile. In the same way, transport the third tile to the steel pipe group circular welding device and install and fix it. Before fixing, remove the positioning plate used when installing the first tile. One end of the third tile is fixed with the first beam body of the main top beam shared by the fixing plate and the first tile, and the other end is fixed with the first beam body of the main top beam shared by the fixing plate and the second tile. After fixing, extend the hydraulic support rod so that the second beam body of the third tile corresponding to the auxiliary top beam is close to the inner arc surface of the third tile, and the third tile is sucked by the magnet or magnetic device arranged thereon to assist in fixing. Finally, after all tiles are installed, rotate the butt weld of the tile to the top of the steel pipe group circular welding device to facilitate the subsequent butt weld welding construction.

[0112] When the weld rotates to the top of the steel pipe assembly welding device, since the welding pad has been installed in the through groove of the main top beam in advance and the bottom is pre-installed with a high-temperature resistant air cushion, an inflating device is used to fill the high-temperature resistant air cushion with air or inert gas, so that the air cushion expands and lifts the welding pad to fit closely to the back of the weld, thereby ensuring that both sides are formed at one time, the back weld is fully formed, the weld trace is neat, and the forming is beautiful. Another implementation method is to arrange a spring between the pad installation box and the through groove. Since the spring has elastic force, the welding pad is lifted up and close to the back of the weld, thereby meeting the welding construction requirements. Because the butt welds between tiles are on the main top beam, it is relatively convenient to calibrate the butt welds between tiles. The main top beam can be used as a support on the back of the tile through auxiliary equipment such as a multi-functional trolley and a jack, so that the butt welds of the tiles can be easily calibrated. After the tiles are assembled into steel pipe sections, the fixing bolts between the fixing plate and the top beam are removed, the pipe section is removed from the steel pipe assembly welding device, and the excess fixing plates on the pipe section are cut and removed.

[0113] The above-mentioned tile assembly method can set the welding pad 14 on the main top beam 1 in advance, and there is no need to stick the welding pad 14 after the weld is formed. The operation is simpler, the welding pad installation process can be optimized, and the construction time is effectively saved; the main top beam 1 with the positioning piece 15 can be used as a basis for positioning, so as to ensure the accuracy of the tile installation position, facilitate tile positioning, and save adjustment time during tile installation; at the same time, with the main top beam 1 as the basis, the butt welds between tiles are no longer in a suspended state, thereby making the seam alignment and shaping between the welds simpler, saving construction time.

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
