Technical Field

[0001] The invention relates to the technical field of cooling circulation tank processing, in particular to a cooling circulation tank processing welding device. Background Art

[0002] As a common heat exchange equipment in industrial processes, the cooling circulation tank has a main structure that is usually welded by a cylindrical tank body and a hemispherical or elliptical head through annular welds, and a mounting hole is opened in the middle of one of the heads. When welding the tank body and the head, the tank body is usually supported by a roller support assembly, and the roller support assembly can drive the tank body and the head to rotate, and then the head is fixed to both ends of the tank body by a roller fixing assembly, and finally the tank body and the head are welded by a welding device.

[0003] The following problems exist when welding the head and the tank body together: 1. When the head is fixed at both ends of the tank body, it is impossible to ensure that the tank body and the head are accurately aligned, and they can only be adjusted manually, which may lead to misalignment or eccentricity between the head and the tank body, thereby reducing the welding quality of the head and the tank body; 2. The existing roller fixing assembly can only press the lower outer part of the head to fix the head and the tank body together, and the roller fixing assembly contacts the curved surface of the head through the roller, which may not stably fix the head and the tank body together, resulting in the head being easily offset due to vibration during the welding process, thereby affecting the stability during welding.

DETAILED DESCRIPTION

[0030] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0031] See also Figure 1 A cooling circulation tank processing and welding device comprises a slide rail base 1, a welding unit 3 is installed on the slide rail base 1, two left and right alignment units 2 are installed on the upper end of the slide rail base 1, and an inner support unit 4 for supporting the inner side of the head is installed on the right alignment unit 2.

[0032] The present invention is used for welding the tank body and the head of a cooling circulation tank, and the present invention can calibrate the head to ensure that the head and the tank body are accurately aligned, thereby ensuring the welding quality of the head and the tank body. At the same time, the present invention can also fix the front and rear sides of the upper welding position of the head and the tank body, thereby increasing the stability during welding.

[0033] Specifically, firstly, the tank body and the two heads are lifted to the top of the slide rail base 1 by an external lifting device, and the head with the installation opening is located on the right side, and then the two positioning units 2 are controlled to move towards each other, so that the left positioning unit 2 moves to the corresponding position of the left head, and the right positioning unit 2 moves to the corresponding position of the right head. At the same time, the right positioning unit 2 drives the internal support unit 4 to insert into the installation opening of the right head, and then the external lifting device is controlled to place the tank body on the two positioning units 2, so that the positioning unit 2 supports the tank body, and at the same time, the head is placed on its corresponding positioning unit 2, and finally the positioning unit 2 is controlled to preliminarily fix the two heads on both sides of the tank body.

[0034] Control the inner support unit 4 to support the inner sides of the two heads, and then start the calibration unit 2 to knock on the heads in a circular manner. When the welding parts of the heads and the tank body are not precisely aligned, the heads can be adjusted in position under the knocking action of the calibration unit 2, so that the heads and the tank body are precisely aligned, and the inner support unit 4 supports the inner sides of the two heads to prevent the heads from being excessively knocked.

[0035] When the alignment of the head is completed, the two alignment units 2 are controlled to completely fix the two heads on both sides of the tank body. Finally, the welding positions of the tank body and the head are moved to the corresponding positions of the welding units 3 respectively by controlling the two alignment units 2. The welding unit 3 is started to weld the head and the tank body. The alignment unit 2 drives the head and the tank body to rotate, so that the welding unit 3 welds the head and the tank body together. The welding unit 3 can fix the front and rear sides of the welding position of the head and the upper part of the tank body, thereby increasing the stability of the head and the tank body during welding.

[0036] When the welding of the head and the tank body is completed, the welding unit 3 is controlled to return to the initial position, and then the welded head and the tank body are initially lifted by the external hoist, and then the two positioning units 2 are controlled to return to the initial position, and the right positioning unit 2 drives the internal support unit 4 to move out of the installation port of the right head, so that the welded head and the tank body can be taken out by the external hoist.

[0037] See also Figure 1 and Figure 2 The calibration unit 2 includes a T-shaped electric slide 21 slidably mounted on the slide rail base 1, and support plates 23 are installed on the opposite sides of the upper ends of the two T-shaped electric slides 21 through height adjustment members 22. A plurality of circumferentially evenly arranged elastic knocking rods 25 are installed on the opposite sides of the two support plates 23 through a rotating mechanism 24. A No. 1 ball is installed on the end of the elastic knocking rod 25 away from the support plate 23, and a knocking mechanism 26 is installed on the end of the plurality of elastic knocking rods 25 close to the support plate 23. The knocking mechanism 26 is used to drive the elastic knocking rod 25 to knock on the head.

[0038] See also Figure 2Two roller supports 27 arranged symmetrically front and back are installed on opposite sides of the upper ends of the two T-shaped electric slides 21. A roller fixing part 28 and a head supporting mechanism 29 are installed in sequence on the upper end of the T-shaped electric slide 21 and on one side of the support plate 23 close to the middle of the slide rail base 1.

[0039] It should be noted that the height adjustment member 22 in the present invention includes a guide shaft and an adjusting screw. The guide shaft is slidably installed on the front side of the support plate 23, and the guide shaft is fixedly connected to the T-shaped electric slide 21. The adjusting screw is installed on the rear side of the support plate 23 by threaded fitting, and the adjusting screw is rotatably connected to the T-shaped electric slide 21. By rotating the adjusting screw, the support plate 23 is driven to move up and down under the action of the guide shaft, thereby realizing the height adjustment of the support plate 23.

[0040] It should be noted that the roller support 27 and the roller fixing member 28 in the present invention both adopt existing technologies, wherein the roller support 27 supports the lower side of the tank body through its rollers, and the rollers of the roller support 27 can drive the tank body to rotate, and the roller fixing member 28 fixes the head and the tank body together through inclined rollers, and its rollers will not affect the rotation of the head driven by the tank body.

[0041] The calibration unit 2 is used to align the head and the tank body; specifically, first, the height of the support plate 23 is adjusted by controlling the height adjustment member 22 according to the size of the tank body, so that the support plate 23 drives multiple elastic knocking rods 25 to be evenly distributed around the center of the tank body through the rotating mechanism 24. When the tank body and the two heads are lifted to the top of the slide rail base 1 by an external lifting device, the two T-shaped electric slides 21 are controlled to move toward each other, so that the T-shaped electric slides 21 drive the roller support 27 to move to the corresponding position of the tank body, and then the external lifting device is controlled to place the tank body on the roller support 27 corresponding to the two T-shaped electric slides 21.

[0042] Continue to control the T-shaped electric slide 21 to move towards each other, so that the T-shaped electric slide 21 drives the roller fixing part 28 to initially fix the two heads on both sides of the tank body, and then control the external hanger to loosen the heads. At the same time, the head support mechanism 29 can support the heads, and at this time, the elastic knocking rod 25 is pressed against the head, and the elastic knocking rod 25 is driven to rotate by controlling the rotating mechanism 24. The elastic knocking rod 25 knocks the head in a circular manner under the action of the knocking mechanism 26. When there is misalignment or eccentricity between the head and the tank body, since the outer side of the head is a spherical surface, the side of the head with misalignment or eccentricity is subjected to a greater knocking force, so that the circular knocking of the elastic knocking rod 25 can calibrate the head, so that the head and the tank body are accurately aligned, and the elastic knocking rod 25 contacts the head through the No. 1 ball, which will not affect the rotation of the head.

[0043] The T-shaped electric slide 21 is controlled to move in the direction of approaching each other again, so that the T-shaped electric slide 21 drives the roller fixing part 28 to completely fix the calibrated head on both sides of the tank body, and the tank body and the head are driven to move synchronously by synchronously controlling the T-shaped electric slide 21, so that the welding point of the tank body and the head can be moved to the corresponding position of the welding unit 3, and the tank body is driven to rotate by controlling the roller support 27, so that the welding unit 3 can weld the head and the tank body together.

[0044] When the welding of the head and the tank body is completed, the welded tank body and the head are driven to move a certain distance by synchronously controlling the T-shaped electric slide 21 so that the welding unit 3 will not block the head and the tank body. The welded head and the tank body are initially lifted by an external hoist, and the two T-shaped electric slides 21 are controlled to move away from each other to the initial position, so that the welded head and the tank body can be taken out.

[0045] See also Figure 2 , Figure 3 and Figure 4 The rotating mechanism 24 includes a sleeve 241 fixedly mounted on opposite sides of the two support plates 23, a rotating plate 242 is rotatably mounted on one end of the sleeve 241 away from the support plate 23, an elastic knocking rod 25 is slidably mounted on the rotating plate 242 left and right, and a rotating active member 243 is connected between the rotating plate 242 and the support plate 23.

[0046] It should be noted that the rotating active member 243 in the present invention includes a rotating shaft, which is fixedly connected to the rotating plate 242, and the sleeve 241 is sleeved on the outside of the rotating shaft. The end of the rotating shaft away from the rotating plate 242 rotates through the support plate 23 and is fixedly sleeved with a gear ring. A gear is meshingly installed under the gear ring, and the gear is connected to the output shaft of the motor fixedly installed on the support plate 23 by a key fit. By starting the motor to drive the gear to rotate, the gear and the gear ring cooperate to drive the rotating plate 242 to rotate through the rotating shaft.

[0047] The rotating mechanism 24 is used to drive the multiple elastic knocking rods 25 to rotate; specifically, the rotating active member 243 is started to drive the rotating plate 242 to rotate, so that the rotating plate 242 drives the multiple elastic knocking rods 25 to rotate synchronously, thereby enabling the elastic knocking rods 25 to knock the head in a circular shape.

[0048] See also Figure 2 , Figure 4 and Figure 5 The knocking mechanism 26 includes a synchronous ring 261 fixedly mounted on one end of a plurality of elastic knocking rods 25 close to the support plate 23, and two symmetrically arranged columnar blocks 262 are fixedly mounted inside the synchronous ring 261.

[0049] See also Figure 4 and Figure 5A plurality of arc-shaped toggle blocks 244 evenly arranged in the circumferential direction are fixedly mounted on one end of the outer side of the sleeve 241 close to the support plate 23 , and one end of the arc-shaped toggle block 244 close to the support plate 23 is configured as an inclined surface for matching with the columnar block 262 .

[0050] The knocking mechanism 26 is used to drive the elastic knocking rod 25 to knock the end caps; specifically, when the roller fixing member 28 initially fixes the two end caps on both sides of the tank body, the elastic knocking rod 25 is initially compressed, so that the elastic knocking rod 25 drives the synchronous ring 261 to move away from the end cap under the blocking effect of the end cap, so that the synchronous ring 261 drives the columnar block 262 to move to the corresponding position of the arc-shaped toggle block 244, and when the rotating plate 242 drives the elastic knocking rod 25 to rotate, the elastic knocking rod 25 drives The dynamic synchronization ring 261 rotates, and when the cylindrical block 262 rotates to the position corresponding to the inclined surface of the arc-shaped toggle block 244, the cylindrical block 262 drives the elastic knocking rod 25 to move away from the head through the synchronization ring 261 under the action of the inclined surface of the arc-shaped toggle block 244. When the cylindrical block 262 and the arc-shaped toggle block 244 are separated, the elastic knocking rod 25 knocks on the head under the action of its elasticity, and the arc-shaped toggle block 244 is provided with multiple ones, so that the elastic knocking rod 25 can continuously knock on the head in a circular shape.

[0051] See also Figure 2 and Figure 5 The head supporting mechanism 29 includes two fixed plates 291 symmetrically arranged on the upper end of the T-shaped electric slide 21, and an arc groove is opened on the upper end of the fixed plates 291. The opposite sides of the two fixed plates 291 are jointly installed with an arc plate 293 through an arc electric slider assembly 292. A plurality of circumferentially uniformly arranged elastic supporting plates 295 are radially slidably installed on the arc plate 293 through a connecting spring 294, and a supporting shaft 296 is rotatably installed on the upper end of the elastic supporting plate 295.

[0052] See also Figure 2 and Figure 5 A supporting reinforcement plate 297 with an arc-shaped structure is fixedly installed on opposite sides of the two fixed plates 291 and located below the arc plate 293. The upper side of the supporting reinforcement plate 297 is in contact with the lower end of the elastic supporting plate 295, and the curvature of the supporting reinforcement plate 297 is greater than the curvature of the arc plate 293.

[0053] The head supporting mechanism 29 is used to support the head; specifically, when the roller support 27 supports the tank body, the support shaft 296 is fitted under the tank body under the action of the elastic support plate 295. At the same time, when the roller fixing member 28 initially fixes the two heads on both sides of the tank body, the support shaft 296 can also fit under the head. When the elastic knocking rod 25 knocks the head in a circular shape, the arc-shaped electric slider assembly 292 is controlled to drive the arc plate 293 to move back and forth, so that the arc plate 293 drives the support shaft 296 to move along the lower surface of the tank body through the elastic support plate 295, and the curvature of the support reinforcement plate 297 is greater than the curvature of the arc plate 293, so that the elastic support plate 295 can move back and forth while being able to move toward the direction close to the tank body under the action of the upper curved surface of the support reinforcement plate 297, thereby increasing the compression of the elastic support plate 295.

[0054] When the head and the tank body are misaligned or eccentric, the support shaft 296 applies an elastic restoring force to the misaligned or eccentric part of the head relative to the tank body under the action of the elastic support plate 295, and then cooperates with the circular knocking of the elastic knocking rod 25 to ensure the precise alignment of the head and the tank body. The compression of the elastic support plate 295 increases under the action of the support reinforcement plate 297, thereby increasing the elastic restoring force applied by the support shaft 296 to the misaligned or eccentric part of the head relative to the tank body, further ensuring the precise alignment of the head and the tank body. When the support shaft 296 applies an elastic force to the position of the head and the tank body that is not misaligned or eccentric under the action of the elastic support plate 295, due to the heavy mass of the tank body, the support shaft 296 will only be close to the surface of the tank body under the action of the elastic support plate 295 but will not affect the position of the tank body, thereby avoiding the misalignment or eccentricity of the originally aligned head and tank body under the action of the support shaft 296.

[0055] See also Figure 6 and Figure 7 The inner support unit 4 includes a plug column 41 installed on the right-side rotating active member 243, a sliding active member 42 is connected between the right end of the plug column 41 and the support plate 23, the left end of the plug column 41 passes through the right-side rotating plate 242, and the left end of the plug column 41 is slidable left and right through a synchronous member 43 and is installed with two left-right symmetrically arranged sliding sleeves 44, the outer side of the sliding sleeve 44 is hinged with a plurality of circumferentially uniformly arranged inner support rods 45, one end of the inner support rod 45 away from the sliding sleeve 44 is tilted away from the plug column 41 and is installed with a No. 3 ball, and an angle adjustment mechanism 46 is installed between the plurality of inner support rods 45 and the plug column 41; initially, the plurality of inner support rods 45 are positioned so that they can be inserted into the mounting port of the right-side head.

[0056] It should be noted that the sliding active member 42 in the present invention includes an L-shaped support frame fixedly installed on the right end of the right support plate 23, a multi-stage push rod is installed on the left side of the vertical section of the support frame, a square frame is fixedly installed on the left side of the multi-stage push rod, and the left end of the square frame is fixedly connected to the plug column 41, the rotating shaft of the right rotating active member 243 is set as a hollow structure, and the plug column 41 is located in the hollow structure of the rotating shaft, and the square frame is driven to move left and right by starting the multi-stage push rod, so that the square frame drives the plug column 41 to move left and right.

[0057] It should be noted that the synchronous part 43 in the present invention includes a bidirectional screw, which is rotatably connected to the plug column 41, and the right end of the bidirectional screw rotates in turn to penetrate the plug column 41 and the square frame and is arranged in the square frame. The bidirectional screw is provided with two threaded sections arranged left and right and with opposite rotation directions. Synchronous blocks are installed on the two threaded sections of the bidirectional screw through the direction of thread matching, and the synchronous blocks are slidably arranged in the plug column 41 left and right. The outer side of the synchronous block is fixedly connected to a plurality of circumferentially evenly arranged transmission blocks and their corresponding sliding sleeves 44, and the transmission block slides left and right through the plug column 41, and the two synchronous blocks are driven to move synchronously by rotating the part of the bidirectional screw located in the square frame, so that the synchronous block drives the two sliding sleeves 44 to move synchronously through the transmission block.

[0058] The inner support unit 4 is used to support the inner side of the head; specifically, when the height of the support plate 23 is adjusted, the support plate 23 drives the plug column 41 and the head to be aligned in the center. When the right T-shaped electric slide 21 is controlled to move toward the direction close to the head, the T-shaped electric slide 21 drives the plug column 41 to be inserted into the installation port of the right head through the support plate 23. After the right roller fixing part 28 initially fixes the right head on the right side of the tank body, the sliding active part 42 is controlled to drive the plug column 41 to move left and right, so that the middle of the opposite sides of the two sliding sleeves 44 are aligned with the middle of the tank body.

[0059] Then, the synchronous component 43 is controlled to drive the two sliding sleeves 44 to move away from each other, so that the inner support rod 45 is rotated a certain angle away from the plug column 41 based on the hinge between it and the sliding sleeve 44 under the action of the angle adjustment mechanism 46. Then, the synchronous component 43 is continued to be controlled to drive the left and right inner support rods 45 to press against the corresponding inner sides of the head respectively through the sliding sleeve 44, so as to support the inner side of the head, so that the inner side of the head after calibration is evenly contacted with the corresponding multiple inner support rods 45, thereby preventing the head from being excessively knocked, and the inner support rod 45 is in contact with the head through the No. 3 ball, which will not affect the rotation of the head.

[0060] When the welded head and tank body need to be taken out, the two sliding sleeves 44 are driven to return to their initial positions in a direction approaching each other by controlling the synchronous part 43, and the inner support rod 45 is rotated to the initial position under the action of the angle adjustment mechanism 46. Then, when the right T-shaped electric slide 21 returns to its initial position in a direction away from the tank body, the right T-shaped electric slide 21 drives the plug 41 to move out of the installation port of the right head through the support plate 23.

[0061] See also Figure 7 The angle adjustment mechanism 46 includes an adjustment sleeve 461 distributed on the opposite sides of the two sliding sleeves 44, and the adjustment sleeve 461 is sleeved on the outside of the plug column 41. The adjustment sleeve 461 is slidably connected to the sliding sleeve 44 left and right through a plurality of circumferentially evenly arranged elastic tension rods 462, and the elastic tension rods 462 are slidably installed in the yield groove of the arc structure preset on the adjustment sleeve 461. The outer side of the adjustment sleeve 461 is provided with an arc groove corresponding to the position of the inner support rod 45, and an arc slider is slidably installed in the arc groove. The end of the arc slider away from the adjustment sleeve 461 is hinged with a connecting block, and the connecting block is slidably connected to the corresponding inner support rod 45; wherein, the inner side of the adjustment sleeve 461 is made of a material with greater friction.

[0062] The angle adjustment mechanism 46 is used to synchronously adjust the angles of multiple inner support rods 45; specifically, initially, the elastic tension rod 462 is in a compressed state. When the two sliding sleeves 44 move away from each other, since the inner side of the adjustment sleeve 461 uses a material with greater friction, the adjustment sleeve 461 is in a stationary state under the tension of the elastic tension rod 462 and the friction between the adjustment sleeve 461 and the plug column 41, so that the distance between the sliding sleeve 44 and the adjustment sleeve 461 is reduced. At the same time, under the action of the arc-shaped slider and the connecting block, the inner support rod 45 is rotated a certain angle in the direction away from the plug column 41 with its hinge with the sliding sleeve 44 as a reference. Similarly, when the two sliding sleeves 44 move to the initial position in the direction of approaching each other, the inner support rod 45 rotates to the initial state.

[0063] See also Figure 8 Two guide grooves 411 are evenly arranged on the outer side of the plug column 41 at positions corresponding to the adjustment sleeve 461. The side of the guide groove 411 close to the adjustment sleeve 461 is set as an inclined structure, and the side of the guide groove 411 away from the adjustment sleeve 461 is set as a horizontal structure. A matching block 412 is slidably installed in the guide groove 411, and the matching block 412 and the adjustment sleeve 461 are fixedly connected. The inclined section of the guide groove 411 is used to cooperate with the matching block 412 to drive the adjustment sleeve 461 to rotate.

[0064] See also Figure 7 , Figure 8 and Fig.10Two circumferentially evenly arranged rotation locking pins 463 are fixedly installed on one side of the adjustment sleeve 461 close to the sliding sleeve 44 , and an L-shaped locking groove is provided on one side of the sliding sleeve 44 close to the adjustment sleeve 461 and at a position corresponding to the rotation locking pins 463 .

[0065] When the sliding sleeve 44 moves to the position close to the adjusting sleeve 461 to the corresponding position of the rotation locking pin 463, the rotation locking pin 463 can be inserted into the corresponding locking groove, and the sliding sleeve 44 drives the adjusting sleeve 461 to move away from the middle of the tank body through the rotation locking pin 463, and at the same time drives the adjusting sleeve 461 to rotate under the cooperation of the inclined section of the guide groove 411 and the matching block 412, so that the adjusting sleeve 461 drives the rotation locking pin 463 to rotate in the locking groove, and then the rotation locking pin 463 and the locking groove cooperate to lock the sliding sleeve 44 and the adjusting sleeve 461 together, and then the adjusting sleeve 461 drives the matching block 412 to move along the horizontal section of the guide groove 411, so that the inner support rod 45 can rigidly support the inner side of the head.

[0066] See also Figure 2 and Fig. 9 The welding unit 3 includes a gantry fixedly mounted on the slide rail base 1, a welding piece 31 is installed in the middle of the lower side of the gantry, two connecting plates 32 arranged symmetrically in front and back are installed on the welding piece 31, a roller 33 is rotatably installed in the middle of the lower end of the connecting plate 32 through two square plates, and two elastic clamping rods 34 arranged symmetrically in the left and right are also fixedly mounted on the lower end of the connecting plate 32, and the lower ends of the two elastic clamping rods 34 are arranged inclined in a direction close to each other and are installed with No. 2 balls.

[0067] It should be noted that the welding part 31 in the present invention adopts the existing technology, including a driving part and a welding head. The driving part is used to drive the welding head to move up and down, so that the welding head moves to the corresponding positions of the tank body and the head. The two connecting plates 32 are both installed on the driving part of the welding part 31.

[0068] The welding unit 3 is used to weld the head and the tank body together; specifically, when the head is initially fixed on the left and right sides of the tank body, the welding piece 31 is controlled to drive the two connecting plates 32 to move downward, so that the connecting plates 32 drive the rollers 33 to press against the upper side of the tank body through the square plates, and at the same time, the elastic pressing rod 34 is pressed against the upper side of the head under its elastic action, and the elastic pressing rod 34 is set to an inclined structure so that it can press the head in the direction close to the tank body, and it is set on the front and rear sides of the welding head of the welding piece 31, so that the elastic pressing rod 34 can press and fix the front and rear sides of the welding point between the head and the tank body, thereby increasing the stability during welding.
