Description

Technical Field

[0001] The invention relates to the technical field of pipeline welding auxiliary devices, in particular to a water-cooled wall pipeline welding butt auxiliary device and method. Background Art

[0002] The water wall is the main heat receiving part of the boiler. It is composed of several rows of pipes distributed around the boiler furnace. Water or steam flows inside the water wall pipes, which mainly absorb the radiation heat of the high-temperature combustion products in the furnace. The welding of water wall pipes is an important link in the manufacturing and installation process of the boiler. Its welding quality directly affects the safety and operation efficiency of the boiler. Before welding, the water wall pipes will be grooved (V-shaped groove). The surface of the butt end of the water wall pipe after the groove is smooth; In the welding process of boiler water-cooled wall pipes, it is necessary to align the two unjointed pipe ends, and then use argon arc welding to weld the grooves. In the actual welding process, the water-cooled wall pipes need to be aligned. The more common method is to clamp the pipes with the aid of an alignment clamp. However, there are often many attachments on the outer wall of the water-cooled wall pipes, such as rust, corrosion or residual paint. Due to the presence of attachments, it is difficult to keep the pipes and the alignment clamps concentric when the clamps are used for alignment. Therefore, the clamps may be aligned but the pipes themselves are not aligned, which may easily lead to misalignment and affect the welding quality. For example, the patent with the publication number CN221159219U is a water-cooled wall pipe row welding alignment clamp. In this patent, the pipe alignment is directly assisted by the clamp, which may cause alignment deviation due to the eccentricity of the pipe and the alignment clamp. Therefore, a water-cooled wall pipe welding butt-jointing auxiliary device and method are proposed. Summary of the invention

[0003] The purpose of the present invention is to provide a water-cooled wall pipe welding docking auxiliary device and method to solve the problem raised in the above background technology that "however, the outer wall of the water-cooled wall pipe may have oil stains, rust or uneven paint thickness, and it is difficult to keep the pipe and the docking clamp concentric, so the clamp may be aligned but the pipe itself is not aligned, which can easily lead to uneven docking and affect the welding quality."

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water-cooled wall pipe welding butt joint auxiliary device, comprising two semi-rings, the outer side walls of the semi-rings are provided with semi-circular sliding rings, the outer side walls of the semi-circular sliding rings are slidably connected with semi-circular slide rails, the outer side walls of the semi-circular slide rails are fixedly connected with semi-circular seats, the outer side walls of the semi-rings are installed with adjustable clamping mechanisms for clamping water-cooled wall pipes, a detection mechanism is installed on one side of the semi-circular seat close to the pipe groove, the outer side wall of the semi-circular seat is installed with a butt joint mechanism, a connection structure 1 is connected between the outer side walls of the two semi-rings, and a connection structure 2 is connected between the outer side walls of the two semi-circular seats; The detection mechanism comprises a connecting rod, one end of the connecting rod is fixedly connected to the lower surface of one of the semicircular seats, the other end of the connecting rod is fixedly connected to a cylinder, the inside of the cylinder is slidably connected to a square rod, the left end of the square rod is fixedly connected to a round head, the inside of the cylinder is provided with a circular groove, the middle of the outer wall of the square rod is fixedly connected to a circular plate, and a spring is fixedly connected between the circular plate and the inner right side wall of the circular groove, the right end of the square rod is provided with a connecting strip, the end of the connecting strip away from the connecting strip is fixedly connected to a toothed plate, the right side wall of the connecting rod is provided with a fixing block, the right end of the fixing block is hinged with a gear, the gear is meshed with the gear plate, the outer side wall of the gear is fixedly connected with a pointer, the side of the fixing block away from the cylinder is provided with a mounting bracket, the right end of the mounting bracket is fixedly connected with a dial, the length of the toothed plate is long and the size of the gear is small, even if the movement amplitude of the toothed plate is small, the toothed plate will have a large rotation amplitude, so as to achieve the effect of amplifying the eccentricity value of the round seat and the water-cooled wall pipeline; Two semi-rings are butted together to form a complete circular ring, two semi-circular seats are butted together to form a complete circular seat, two semi-circular slip rings are butted together to form a complete slip ring, and two semi-circular slide rails are butted together to form a complete slide rail. The slide rail slides on the outer wall of the slip ring to drive the circular seat to rotate, so that the circular seat has a rotation function. When the semi-circular seat is rotated, the round head of the detection mechanism walks on the groove of the water-cooled wall pipe. During this process, the swing amplitude of the pointer represents the degree of deviation between the center of the semi-circular seat and the center of the water-cooled wall pipe. If the swing amplitude is too large, the semi-circular seat and the water-cooled wall pipe are kept concentric through the adjustable clamping mechanism, and the semi-circular seat is used to achieve the matching positioning to reduce the matching deviation.

[0005] The present invention can use the "groove" of the water-cooled wall pipe as a reference surface to detect the concentricity of the two pipes, and then adjust them again to make the two pipes concentric. This setting can greatly increase the accuracy of the matching, making the deviation less than 0.5mm, thereby ensuring the quality of welding.

[0006] The round seat is rotated to make the round head circle around the surface of the smooth groove after grinding. Under the elastic force of spring 2, the round head remains in contact with the groove of the water-cooled wall pipe. If there is a deviation between the center of the round seat and the pipe, the square rod will be displaced when the round seat is rotated to drive the tooth plate to move, thereby driving the pointer to swing. According to the swing of the pointer, the position of the round seat is adjusted with the help of an adjustable clamping mechanism to keep the round seat concentric with the water-cooled wall pipe, and then the two water-cooled wall pipes are positioned with the help of the positioning rod on the surface of the round seat, avoiding the adverse effects of oil stains, rust or uneven paint thickness on the outer wall of the pipe on the pipe, which is conducive to improving the accuracy of the pipe.

[0007] As a further preferred embodiment of the present technical solution: the docking mechanism comprises a positioning block, the outer side wall of the semicircular seat is evenly and fixedly connected with the positioning block, the upper surface of the positioning block is provided with a positioning hole, and the inner side wall of the positioning hole is inserted with a positioning rod.

[0008] As a further preferred embodiment of the present technical solution: the adjustable clamping mechanism includes an installation groove, two installation grooves are symmetrically opened on one side of the semi-ring close to the bevel of the water-cooled wall pipe, the inner wall of the semi-ring is symmetrically slidably connected to two sliding rods, one end of the sliding rod extends into the installation groove, and the other end of the sliding rod is hinged with a clamping plate, and two fixing frames are symmetrically fixedly connected to one side of the semi-ring close to the installation groove, and the outer wall of the fixing frame is threadedly connected with a threaded rod, and the end of the threaded rod close to the semi-ring is rotatably connected to a lifting block through a bearing, and a transmission rod is hinged on the side of the lifting block away from the threaded rod, and the end of the transmission rod away from the lifting block is hinged to the outer wall of the sliding rod.

[0009] As a further preferred embodiment of the technical solution: two connecting blocks are symmetrically fixedly connected to the outer side wall of the slide rod, and a spring 1 is fixedly connected between the connecting block and the opposite side of the installation groove.

[0010] Under the above settings, if the pointer swings too much to the right, it means that the center of the round seat is biased to the right. At this time, find the nearest threaded rod, rotate the threaded rod counterclockwise and rotate the threaded rod opposite to the threaded rod clockwise to adjust the position of the round seat to the left. Similarly, if the pointer swings too much to the left, it means that the center of the round seat is biased to the left. Find the nearest threaded rod, rotate the threaded rod opposite to the threaded rod counterclockwise, and rotate the threaded rod itself clockwise to adjust the position of the round seat to the right so that the round seat and the water-cooled wall pipe are concentric. The right in the above is the direction away from the water-cooled wall pipe, and the left is the direction close to the water-cooled wall pipe. When the threaded rod rotates clockwise, the threaded rod pushes the transmission rod, and the transmission rod pushes the sliding rod and the splint to move the splint toward the pipe. Once the spring is compressed, when the threaded rod rotates counterclockwise, the threaded rod pulls the transmission rod, and the transmission rod pulls the sliding rod and the splint to move the splint away from the pipe. Once the spring is extended, it can assist the movement of the splint.

[0011] As a further preferred embodiment of the technical solution: the lifting block is symmetrically fixedly connected to two guide rods on one side away from the transmission rod, the guide rods are slidably connected to the fixed frame, and the end of the threaded rod away from the lifting block is fixedly connected to a knob 1.

[0012] As a further preferred embodiment of the present technical solution: a blind groove is provided on the right side wall of the square rod, a sliding bar is slidably connected to the inner wall of the blind groove, the connecting bar is fixedly connected to an adjacent side of the sliding bar, a push rod is threadedly connected to the right side of the front surface of the square rod, and a knob 2 is fixedly connected to the front end of the push rod.

[0013] As a further preferred embodiment of the present technical solution: the connection structure 1 includes a T-shaped groove, the left side wall of one of the semi-rings is symmetrically provided with two T-shaped grooves, and the right side wall of the other semi-ring is symmetrically fixedly connected with two T-shaped blocks, and the T-shaped blocks can be plugged into the T-shaped grooves.

[0014] As a further preferred embodiment of the technical solution: the outer wall of one of the semi-rings is symmetrically fixedly connected with four locking blocks, the outer wall of the locking blocks is provided with locking holes, and the outer wall of the other semi-ring is symmetrically fixedly connected with four mounting blocks, the outer wall of the mounting blocks is slidably connected with locking rods, and the locking rods can be plugged into the locking holes.

[0015] As a further preferred embodiment of the present technical solution: the second connecting structure includes a slot, two slots are symmetrically provided on the left side wall of one of the semicircular seats, and two plug plates are symmetrically and fixedly connected to the right side wall of the other semicircular seat, and two clamping plates are symmetrically and slidably connected to the left side of the upper surface of one of the semicircular seats, one end of the clamping plate extends into the slot, and the other end of the clamping plate is fixedly connected to a movable plate, and a spring three is fixedly connected between the movable plate and the opposite side of the semicircular seat, a clamping groove is provided on the outer side wall of the plug plate, the right side wall of the plug plate is a smooth inclined surface, the side of the clamping plate extending into the slot is a smooth inclined surface, and a pull ring is fixedly connected to the side of the movable plate away from the spring three.

[0016] Under the above settings, when docking two half rings, insert the T-shaped block into the T-shaped slot to achieve a quick connection between the two half rings, insert the locking rod into the locking hole, and the two half rings can be horizontally aligned to avoid misalignment. When docking two semicircular seats, insert the plug plate into the slot, the plug plate squeezes the card plate to make the card plate extend out of the semicircular seat, and the spring three is stretched. When the position of the card plate and the card slot are relative, the spring three shortens and pulls the card plate into the card slot, locking the plug plate to achieve a fixed connection between the two semicircular seats.

[0017] The present invention also provides a method for using the water-cooled wall pipe welding butt auxiliary device, comprising the following steps: S1. Butt the half rings together to form a complete ring, and respectively put them on the two water-cooled wall pipes to be welded. By rotating the threaded rod clockwise, the threaded rod moves and pushes the lifting block, the transmission rod, the sliding rod and the clamping plate, so that the clamping plate clamps the water-cooled wall pipe and fixes the ring on the outer wall of the pipe; S2. Put the semicircular slide rail on the semicircular slip ring, connect the semicircular seat to form a complete round seat, rotate the round seat, and keep the round head in contact with the groove of the water-cooled wall pipe under the elastic force of the second spring. If there is a deviation between the center of the round seat and the pipe, the square rod will be displaced when the round seat is rotated, driving the tooth plate to move, thereby driving the pointer to swing; S3. If the pointer swings too far to the right, it means that the center of the round seat is biased to the right. At this time, find the nearest threaded rod, rotate it counterclockwise and rotate the threaded rod opposite to it clockwise to adjust the position of the round seat to the left. Similarly, if the pointer swings too far to the left, it means that the center of the round seat is biased to the left. Make corresponding adjustments to the corresponding two splints. S4. When the round seat rotates a complete circle and the pointer swings in a small amplitude, it means that the center of the two semicircular seats is basically coincident with the center of the water-cooled wall pipe. At this time, the positioning rod is passed through the positioning holes on the two opposite positioning blocks to assist the two water-cooled wall pipes to complete the welding.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. When the semicircular seat of the present invention rotates, the round head of the detection mechanism moves on the groove of the water-cooled wall pipe. During this process, the swing amplitude of the pointer represents the degree of deviation between the center of the semicircular seat and the center of the water-cooled wall pipe. If the swing amplitude is too large, the semicircular seat and the water-cooled wall pipe are kept concentric through the adjustable clamping mechanism, and the semicircular seat is used to achieve the matching positioning and reduce the matching deviation.

[0019] 2. The present invention can use the "groove" of the water-cooled wall pipe as a reference surface to detect the concentricity of the two pipes, and then adjust them again to make the two pipes concentric. This setting can greatly increase the accuracy of the joint, reduce the deviation, and ensure the quality of welding.

[0020] 3. The present invention rotates the round seat to make the round head circle around the surface of the smooth groove after grinding. Under the elastic force of the second spring, the round head remains in contact with the groove of the water-cooled wall pipe. If there is a deviation between the center of the round seat and the center of the pipe, the square rod will be displaced when the round seat is rotated to drive the tooth plate to move, thereby driving the pointer to swing. According to the swing of the pointer, the position of the round seat is adjusted with the help of an adjustable clamping mechanism to keep the round seat concentric with the water-cooled wall pipe, and then the two water-cooled wall pipes are positioned with the help of a positioning rod on the surface of the round seat, thereby avoiding the adverse effects of oil stains, rust or uneven paint thickness on the outer wall of the pipe on the pipe alignment, which is conducive to improving the alignment accuracy.

[0021] 4. When the present invention is working, if the pointer swings too much to the right, it means that the center of the round seat is biased to the right. At this time, find the nearest threaded rod, rotate the threaded rod counterclockwise and rotate the threaded rod opposite to the threaded rod clockwise to adjust the position of the round seat to the left. Similarly, if the pointer swings too much to the left, it means that the center of the round seat is biased to the left. Find the nearest threaded rod, rotate the threaded rod opposite to the threaded rod counterclockwise and rotate the threaded rod itself clockwise to adjust the position of the round seat to the right so that the round seat and the water-cooled wall pipe are concentric.

[0022] 5. When the two half rings are docked, the T-shaped block is inserted into the T-shaped slot to achieve a quick connection between the two half rings. The locking rod is inserted into the locking hole to align the two half rings horizontally to avoid misalignment. When the two semicircular seats are docked, the plug plate is inserted into the slot. The plug plate squeezes the card plate so that the card plate extends out of the semicircular seat. The spring three is stretched. When the position of the card plate and the card slot is relative, the spring three is shortened to pull the card plate into the card slot, and the plug plate is locked to achieve a fixed connection between the two semicircular seats.

This setting can greatly increase the accuracy of the matching, make the deviation less than 0.5mm, and ensure the quality of welding.

[0028] The round seat is rotated to make the round head 64 circle around the surface of the smooth groove after grinding. Under the elastic force of the spring 2 67, the round head 64 remains in contact with the groove of the water-cooled wall pipe. If there is a deviation between the center of the round seat and the pipe, the square rod 63 will be displaced when the round seat is rotated to drive the tooth plate 69 to move, thereby driving the pointer 612 to swing.

[0039] In this embodiment, specifically: the connection structure 2 9 includes a slot 91, two slots 91 are symmetrically opened on the left side wall of a semicircular seat 4, two plug plates 92 are symmetrically fixedly connected to the right side wall of the other semicircular seat 4, and two clamping plates 93 are symmetrically slidably connected to the left side of the upper surface of a semicircular seat 4, one end of the clamping plate 93 extends into the slot 91, and the other end of the clamping plate 93 is fixedly connected to a movable plate 95, and a spring three 96 is fixedly connected between the movable plate 95 and the opposite side of the semicircular seat 4, a clamping groove 94 is opened on the outer side wall of the plug plate 92, the right side wall of the plug plate 92 is a smooth inclined surface, the side of the clamping plate 93 extending into the slot 91 is a smooth inclined surface, and the side of the movable plate 95 away from the spring three 96 is fixedly connected to a pull ring 97.

[0041] The present invention also provides a method for using the water-cooled wall pipe welding butt auxiliary device, comprising the following steps: S1, butt the half ring 1 to form a complete ring, so that it is respectively placed on the two water-cooled wall pipes to be welded, and by rotating the threaded rod 55 clockwise, the threaded rod 55 moves and pushes the lifting block 56, the transmission rod 57, the sliding rod 52 and the clamping plate 53, so that the clamping plate 53 clamps the water-cooled wall pipe and fixes the ring on the outer wall of the pipe; S2, put the semicircular slide rail 3 on the semicircular slip ring 2, connect the semicircular seat 4 to form a complete round seat, rotate the round seat, and keep the round head 64 in contact with the groove of the water-cooled wall pipe under the elastic force of the spring 2 67. If there is a deviation between the center of the round seat and the pipe, the square rod 63 will be displaced when the round seat is rotated, driving the tooth plate 69 to move, thereby driving the pointer 612 to swing; S3, if the pointer 612 swings too far to the right, it means that the center of the round seat is biased to the right. At this time, find the nearest threaded rod 55, rotate the threaded rod 55 counterclockwise and rotate the threaded rod 55 opposite to the threaded rod 55 clockwise to adjust the position of the round seat to the left. Similarly, if the pointer 612 swings too far to the left, it means that the center of the round seat is biased to the left. Make corresponding adjustments to the corresponding two clamping plates 53. S4. When the round seat rotates a complete circle and the swing amplitude of the pointer 612 is small, it means that the center of the two semicircular seats 4 is basically coincident with the center of the water-cooled wall pipe. At this time, the positioning rod 73 is passed through the positioning holes 72 on the two opposite positioning blocks 71 to assist the two water-cooled wall pipes to complete the welding.
