Description

Technical Field

[0001] The present application relates to the technical field of ventilation duct processing, and in particular to a ventilation duct welding device for chemical equipment. Background Art

[0002] Ventilation ducts are used to transport air from one area to another to ensure good air flow and ventilation. Before the ventilation ducts are put into use, multiple single ventilation ducts of the same specification are welded together, and then the multiple welded ventilation ducts are spliced ​​one by one to form a complete duct ventilation system, thereby ensuring the stable use of the duct ventilation system.

[0003] Before welding multiple ventilation ducts of the same specification, it is necessary to clamp the outer wall of the ventilation duct by a clamp, and then use other driving devices to make the clamp close to align the welding surfaces of the ducts, and then move the welding gun to the corresponding welding position, and then rotate the welding gun around the welding surface to achieve the welding of the duct. The welding steps are cumbersome and it is easy for the duct to sag and deform during the clamping process, thereby affecting the overall strength of the duct. At the same time, the sag and deformation may also cause the welding surface to be dislocated and deformed, thereby affecting the welding quality of the ventilation duct. If the method of lateral pushing at both ends is adopted, the horizontal feeding of the duct is affected, and external lifting equipment is required for operation. At the same time, it is difficult to achieve the welding of multiple ducts at the same time, thereby increasing the time required for welding multiple ducts and reducing the welding efficiency.

[0004] It is difficult for existing welding equipment to automatically adjust the welding position of the welding gun according to ventilation ducts of the same specification and different lengths, and thus more investment is required in driving and electrical equipment, which increases the cost of using the equipment.

[0043] The following describes a chemical equipment ventilation duct welding device according to an embodiment of the present application with reference to the accompanying drawings.

[0044] like Figure 1-Figure 10As shown, the chemical equipment ventilation duct welding device according to the embodiment of the present application includes: an assembly mechanism 1, a drive clamping mechanism 2, a weld distance adjustment mechanism 3 and a welding mechanism 4.

[0045] like Figure 1 and Figure 2 As shown, an assembly mechanism 1, a driving clamping mechanism 2, the driving clamping mechanism 2 is arranged in the middle of the bottom surface of the assembly mechanism 1, the driving clamping mechanism 2 makes the welds of multiple pipes quickly aligned, a weld distance adjustment mechanism 3, the weld distance adjustment mechanism 3 is arranged in the middle of the assembly mechanism 1 and the driving clamping mechanism 2, the driving clamping mechanism 2 drives the weld distance adjustment mechanism 3 to slow down and rotate, a welding mechanism 4, the welding mechanism 4 is arranged in the middle of the assembly mechanism 1 and the driving clamping mechanism 2, the welding mechanism 4 is arranged on the upper part of the weld distance adjustment mechanism 3, the driving clamping mechanism 2 reduces the rotation speed through the weld distance adjustment mechanism 3 to adjust the weld position of the welding mechanism 4.

[0046] When in use, by driving the clamping mechanism 2, three ventilation ducts of the same length and diameter can be driven at both ends by mutual pushing force, and the welding surfaces of the ventilation ducts at both ends will contact the welding surface of the middle ventilation duct and push the middle ventilation duct to move. The ventilation duct in the middle will move to the middle of the assembly mechanism 1, so that the three ventilation ducts can be positioned at the same time and the welding surfaces can be aligned, reducing the time required for welding multiple pipes. At the same time, driving the clamping mechanism 2 will reduce the rotation speed through the weld distance adjustment mechanism 3 to drive the welding mechanism 4 to move toward each other, so that the weld position is automatically adjusted according to the length of the ventilation duct, reducing the investment in driving and electrical equipment and reducing the use cost of the equipment.

[0047] like Figure 3 As shown, the assembly mechanism 1 includes a welding frame 101 and a placement frame 102. The two placement frames 102 are respectively fixedly connected to the front end and the rear end of the welding frame 101. A sliding arc groove 103 is opened at one end of the inner bottom surface of the placement frame 102 close to the middle of the welding frame 101. During the movement of the weld distance adjustment mechanism 3, the long support arc plate 309 will slide inside the sliding arc groove 103, thereby making it less likely for the long support arc plate 309 to deflect and shake during movement.

[0048] like Figure 4 and Figure 510. The driving clamping mechanism 2 includes a first servo motor 201, a bidirectional threaded cylinder 203, an adjusting cover 205, a unidirectional threaded rod 206, an adjusting frame 211, an adjusting tooth plate 212 and a clamping arc plate 213. The first servo motor 201 is fixedly connected to the middle part of the front end of the welding frame 101, and the output end of the first servo motor 201 is fixedly connected to the first rotating rod 202. The bidirectional threaded cylinder 203 is respectively fixedly connected to the outer walls of the front end and the rear end of the first rotating rod 202. The outer wall of the bidirectional threaded cylinder 203 is sleeved with a first threaded sleeve 204. The two adjusting covers 205 are fixedly connected to the upper surface of the first threaded sleeve 204. The two unidirectional threaded rods 206 are rotatably connected to the middle part of the bottom surface of the adjusting cover 205. The rod body of the unidirectional threaded rod 206 is sleeved with a second threaded sleeve. The threaded sleeve 207, the upper surface of the second threaded sleeve 207 is fixedly connected with a connecting plate 210, and the two clamping arc plates 213 are respectively fixedly connected to the upper surface of the connecting plate 210, the inner walls of the two sides of the placement frame 102 are fixedly connected to the limiting frame 214, the two adjustment frames 211 are respectively arranged on one side of the front end and the rear end of the welding frame 101, and the two adjustment tooth plates 212 are respectively fixedly connected to the other side of the adjustment frame 211, and the outer wall of the lower end of the one-way threaded rod 206 is fixedly connected with an adjusting gear 218, and the adjusting tooth plate 212 is meshed with one side of the adjusting gear 218. The inner wall of the adjusting cover 205 is provided with a plurality of limiting grooves 208, and the outer wall of the second threaded sleeve 207 is fixedly connected with a plurality of limiting blocks 209, and the limiting blocks 209 are all inside the limiting grooves 208. Sliding connection, both sides of the lower surface of the clamping arc plate 213 are fixedly connected to the limiting seat 215, and the lower ends of the limiting seats 215 are slidably connected inside the limiting frame 214. Both sides of the front end and the rear end of the inner bottom of the welding frame 101 are fixedly connected with a positioning frame 217, and the outer walls on both sides of the first threaded sleeve 204 are fixedly connected to the limiting plates 216, and the ends of the limiting plates 216 away from the first threaded sleeve 204 are slidably connected inside the positioning frame 217. Specifically, when it is necessary to weld the ventilation ducts, first, three ventilation ducts of the same length and diameter to be welded are assembled on the upper part of the placement frame 102. At this time, by starting the first servo motor 201, the first threaded sleeve 204 can drive the adjusting cover 205 to move toward the direction of the ventilation duct. During the movement of the cover 205, the adjusting gear 218 will mesh with the adjusting tooth plate 212. At this time, the one-way threaded rod 206 starts to rotate and enables the second threaded sleeve 207 to drive the connecting plate 210 and the clamping arc plate 213 to move upward. When the adjusting gear 218 is no longer meshed with the adjusting tooth plate 212, the connecting plate 210 and the clamping arc plate 213 stop rising. At this time, the clamping arc plate 213 begins to contact with the ventilation duct under the action of the first threaded sleeve 204 and positions the ventilation duct. At this time, the three ventilation pipes of the same length and diameter are driven by each other at both ends. The welding surfaces of the ventilation ducts at both ends will contact with the welding surfaces of the middle ventilation duct and push the middle ventilation duct to move. The ventilation duct located in the middle will move to the middle of the welding frame 101.The three ventilation ducts can be positioned at the same time and the welding surfaces can be aligned, thereby effectively reducing the time required for welding multiple ducts and improving the welding efficiency. At the same time, after the ventilation ducts are welded, the first threaded sleeve 204 is returned to its original position by rotating the first servo motor 201 in the opposite direction, and the adjusting gear 218 is returned to its original position under the action of the adjusting tooth plate 212. The welded ventilation ducts can be removed by pushing them to the left or right, which brings convenience to the staff in the unloading work.

[0049] like Figure 6 , Figure 7 and Figure 8 As shown, the weld distance adjustment mechanism 3 includes a fixed frame 301, a bidirectional threaded rod 302, an auxiliary gear 303, a support frame 305, a main gear 310, a guide rail 311, a guide slide 312, a reduction transmission gear 315, an intermediate gear 316, a reset spring 318 and a top pressure rod 321. A mounting groove 104 is provided in the middle of the bottom surface of the welding frame 101, the fixed frame 301 is fixedly connected to one side of the middle of the mounting groove 104, the bidirectional threaded rod 302 is rotatably connected to the upper end of the fixed frame 301, the auxiliary gear 303 is fixedly connected to the outer wall of the rear end of the bidirectional threaded rod 302, the rod body of the bidirectional threaded rod 302 is sleeved with two third threaded sleeves 304, the two support frames 305 are fixedly connected to the upper surface of the third threaded sleeve 304, the end of the support frame 305 away from the middle of the welding frame 101 is fixedly connected to a plurality of connecting round rods 307, and the end of the connecting round rod 307 away from the middle of the welding frame 101 is fixedly connected to a semi-arc concave cover 308;

[0050] The main gear 310 is fixedly connected to the outer wall of the rear end of the first rotating rod 202, the guide rail 311 is fixedly connected to one side of the middle part of the mounting groove 104, the guide slide 312 is slidably connected inside the guide rail 311, the top pressure plate 313 is fixedly connected to the rear end of the upper surface of the guide slide 312, the upper ends of the guide slide 312 and the top pressure plate 313 are rotatably connected to the third rotating rod 314, the reduction transmission gear 315 is fixedly connected to the outer wall of the third rotating rod 314, the intermediate gear 316 is fixedly connected to the outer wall of the rear end of the third rotating rod 314, one side of the front end of the mounting groove 104 is fixedly connected to a fixed block 317, two return springs 318 are fixedly connected to the outer wall of the rear end of the fixed block 317, and the outer wall of the rear end of the return spring 318 is fixedly connected to the first connecting rod 314. The outer wall of the rear end of the first connecting block 319 is fixedly connected to the outer wall of the front end of the guide slide 312, and the middle part of the limiting plate 216 on the rear end side is fixedly connected to the second connecting block 320, and the middle part of the outer wall of the front end of the second connecting block 320 is fixedly connected to the push rod 321, and the front end of the push rod 321 is tightly fitted with the rear end of the push plate 313. The upper surface of the support frame 305 is fixedly connected to the short support arc plate 306, and the upper end of the semi-arc concave cover 308 away from the middle of the welding frame 101 is fixedly connected to the long support arc plate 309. The main gear 310 and the intermediate gear 316 are meshed with each other, and the reduction transmission gear 315 and the auxiliary gear 303 are meshed with each other. Specifically, when welding three ventilation ducts of the same length and diameter, by starting the first servo The servo motor 201 causes the clamping arc plate 213 to push and clamp the ventilation duct. During the movement of the clamping arc plate 213, the limit plate 216 and the second connecting block 320 on the rear end side cause the push rod 321 to push the push plate 313 and the guide slide 312 to slide inside the guide rail 311, and the return spring 318 begins to be slowly compressed. Since the first rotating rod 202 drives the main gear 310 to rotate, the main gear 310 is constantly meshing with the intermediate gear 316, and the rotation speed of the reduction transmission gear 315 is consistent with the rotation speed of the first rotating rod 202. Before the limit seat 215 slides inside the limit frame 214, the reduction transmission gear 315 is in an idling state under the action of the return spring 318 and does not mesh with the intermediate gear 316. When the limit seat 215 slides inside the limit frame 214, the reduction transmission gear 315 begins to mesh with the auxiliary gear 303 and drives the bidirectional threaded rod 302 to rotate. Since the number of gears of the auxiliary gear 303 is three times that of the reduction transmission gear 315, the rotation speed of the bidirectional threaded rod 302 is three times slower than that of the first rotating rod 202. At this time, the movement speed of the first threaded sleeve 204 is three times that of the third threaded sleeve 304. Therefore, when welding ventilation ducts of the same length and diameter of various specifications, when the clamping arc plate 213 pushes the clamping step to complete, the welding mechanism 4 can reach the corresponding welding position driven by the third threaded sleeve 304, thereby reducing the investment in driving and electrical equipment and reducing the use cost of the equipment.By starting the servo motor to rotate, firstly, the ventilation duct before welding and the ventilation duct after welding will not be affected by the clamping arc plate 213 during the loading and unloading process, and the ventilation duct can be unloaded horizontally without the need for other lifting equipment. At the same time, the functions of rapid alignment of the welding surface of the ventilation pipe and automatic adjustment of the welding gun position are realized, which greatly simplifies the pipeline welding steps and realizes the simultaneous welding of multiple pipelines, ensuring the quality of pipeline welding. Secondly, multiple ventilation ducts can be positioned at the same time and the welding surfaces can be aligned, thereby effectively reducing the time required for welding multiple pipelines and improving the welding efficiency. Thirdly, while aligning the welding surfaces of multiple ventilation ducts, the position of the welding gun 409 can also be automatically adjusted according to the length of the pipeline, thereby simplifying the welding process and reducing the investment in drive and electrical equipment, thereby reducing the cost of equipment use.

[0051] like Fig. 9 and Fig.10 As shown, the welding mechanism 4 includes a support frame 401, a second servo motor 402 and a driving gear 404, the two support frames 401 are fixedly connected to the outer wall of one side of the welding frame 101, the second servo motor 402 is fixedly connected to the upper end of the front support frame 401, the output end of the second servo motor 402 is fixedly connected to the fourth rotating rod 403, the two driving gears 404 are respectively fixedly connected to the outer walls of the front and rear ends of the fourth rotating rod 403, the upper ends of the two semi-arc concave covers 308 are fixedly connected to the annular seat 405, the two annular frames 406 are respectively rotatably connected to the annular seats 405, the outer walls of the annular frames 406 are fixedly connected to a plurality of transmission teeth 407, the middle part of the inner top surface of the annular frame 406 is fixedly connected to the electric telescopic rod 408, the output end of the electric telescopic rod 408 is fixedly connected to the welding gun 409, and one end of the annular frame 406 close to the middle of the welding frame 101 A wiring groove 410 is provided, and the transmission teeth 407 are meshed with the driving gear 404. Specifically, when the third threaded sleeve 304 drives the support frame 305, the connecting round rod 307 and the semi-arc concave cover 308 to move, the semi-arc concave cover 308 will drive the annular seat 405 to move toward each other, thereby achieving the function of correspondingly adjusting the position of the welding gun 409. At the same time, during the process of the annular seat 405 moving toward each other, the transmission teeth 407 will continuously mesh with the driving gear 404. After the position of the annular seat 405 is determined, the electric telescopic rod 408 is started to move the welding gun 409 to the designated welding position. By starting the second servo motor 402, the fourth rotating rod 403 can drive the driving gear 404 to rotate. At this time, the annular frame 406 will drive the welding gun 409 to rotate under the action of the meshing of the transmission teeth 407, thereby realizing the welding work of the ventilation duct.

[0052] Specifically, the working principle of the ventilation duct welding device of the chemical equipment is as follows: when the ventilation duct needs to be welded, firstly, three ventilation ducts of the same length and diameter to be welded are assembled on the upper part of the placement frame 102, and then by starting the first servo motor 201, the first threaded sleeve 204 can drive the adjusting cover 205 to move toward the direction of the ventilation duct. During the movement of the adjusting cover 205, the adjusting gear 218 will mesh with the adjusting tooth plate 212. At this time, the one-way threaded rod 206 starts to rotate and enables the second threaded sleeve 207 to drive the connecting plate 210 and the clamping arc plate 213 to move upward. When the adjusting gear 218 is not meshed with the adjusting tooth plate 212, the connecting plate 210 and the clamping arc plate 213 stop rising. At this time, the clamping arc plate 213 is in the first The threaded sleeve 204 starts to contact with the ventilation duct and positions the ventilation duct. At this time, the three ventilation pipes of the same length and diameter are pushed by each other at both ends, and the welding surfaces of the ventilation ducts at both ends will contact with the welding surface of the middle ventilation duct and push the ventilation duct in the middle to move. The ventilation duct in the middle will move to the middle of the welding frame 101, so that the three ventilation ducts can be positioned at the same time and the welding surfaces can be aligned, thereby effectively reducing the time required for welding multiple pipes and improving the welding efficiency. At the same time, after the welding of the ventilation duct is completed, the first threaded sleeve 204 is returned to its original position by rotating the first servo motor 201 in the opposite direction, and the adjusting gear 218 will return to its original position under the action of the adjusting tooth plate 212. The ventilation duct after welding is completed. The cam 315 is pressed against the work surface of the workpiece 200, and the cam 316 is pressed against the workpiece 201. The cam 315 is pressed against the workpiece 200, and the workpiece 200 is pressed against the workpiece 201. Before the seat 215 slides inside the limit frame 214, the reduction transmission gear 315 is in an idling state and does not mesh with the intermediate gear 316 under the action of the return spring 318. When the limit seat 215 slides inside the limit frame 214, the reduction transmission gear 315 begins to mesh with the auxiliary gear 303 and drives the two-way threaded rod 302 to rotate. Since the number of gears of the auxiliary gear 303 is three times more than the number of gears of the reduction transmission gear 315, the rotation speed of the two-way threaded rod 302 is three times slower than that of the first rotating rod 202. At this time, the movement speed of the first threaded sleeve 204 is three times that of the third threaded sleeve 304. Then, when welding ventilation ducts of the same length and diameter of various specifications, when the clamping arc plate 213 pushes the clamping step to be completed,The welding mechanism 4 can reach the corresponding welding position under the drive of the third threaded sleeve 304, thereby reducing the investment in driving and electrical equipment and reducing the use cost of the equipment. When the third threaded sleeve 304 drives the support frame 305, the connecting round rod 307 and the semi-arc concave cover 308 to move, the semi-arc concave cover 308 will drive the annular seat 405 to move toward each other, thereby achieving the function of correspondingly adjusting the position of the welding gun 409. At the same time, during the process of the annular seat 405 moving toward each other, the transmission teeth 407 will continuously mesh with the driving gear 404. After the position of the annular seat 405 is determined, the electric telescopic rod 408 is started to move the welding gun 409 to the specified welding position. By starting the second servo motor 402, the fourth rotating rod 403 can drive the driving gear 404 to rotate. At this time, the annular frame 406 will drive the welding gun 409 to rotate under the meshing of the transmission teeth 407, thereby realizing the welding work on the ventilation duct.

[0053] It should be noted that the specific models and specifications of the first servo motor 201, the second servo motor 402, the electric telescopic rod 408 and the welding gun 409 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
