Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a preheating support device for circumferential weld seam welding. Background Technology

[0002] Proper preheating of the workpiece is an important step in the welding process. Its purpose is to reduce the cooling rate of the weld joint, avoid the formation of hardened structures, reduce welding stress and deformation, and effectively prevent welding cracks, thereby improving welding quality. For example, for some large special steel structures and engineering machinery structural components, preheating before welding is particularly critical due to their material and structural characteristics.

[0003] According to the patent application published on the Internet (authorization announcement number: CN 117086522B), "This invention discloses a preheating device for circumferential welding of towers, belonging to the technical field of tower welding. It includes a base, on which two cylinder rotation mechanisms are arranged symmetrically. The tower body is supported on both cylinder rotation mechanisms. An inner and outer bidirectional preheating mechanism is arranged near each cylinder rotation mechanism. Through this invention, the welding position is preheated before circumferential welding of the tower, so that the inner and outer sides of the welding position can be uniformly heated in a short time, effectively avoiding temperature differences. At the same time, it reduces welding stress and welding strain rate, avoids welding cracks, and facilitates the escape of hydrogen from the weld metal, preventing hydrogen-induced cracks. It also reduces the hardening degree of the weld and heat-affected zone, improving the crack resistance of the welding position."

[0004] Regarding the above description, the applicant believes the following problems exist: The device first places the tower body on the rotating mechanism, then holds the insert rod and rotates the rotating block through the shaft to make the two flamethrowers vertical. Then, the lower end of the insert rod is inserted into the positioning hole to position the rotation range of the rotating block. At this time, the output end of the first flamethrower is aligned with the outer edge of the welding position of the tower body, and the output end of the second flamethrower is aligned with the inner edge of the welding position of the tower body. Then, gas is supplied for ignition, and the motor is turned on at the same time. The intermediate shaft then rotates, and the intermediate shaft drives the first and second support shafts to rotate synchronously and in the same direction through the first, second, third, and fourth pulleys and the belt. This drives the tower body to rotate for preheating. The device places the tower directly on the rotating structure without restraining the tower, which may cause the tower to fall off.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-3This utility model provides an embodiment: a preheating support device for circumferential weld seam welding, including a base 1, a motor 210, and a preheating component. A tower 4 is provided on the outside of the base 1. The motor 210 is fixedly connected to the top of the base 1. The preheating component is provided on the top of the base 1.

A threaded rod 209 is fixedly connected externally to the bevel gear 212. A support 201 is threaded externally to the threaded rod 209. A motor 205 is fixedly connected externally to the support 201. A gear with a spur is fixedly connected to the output end of the motor 205. A gear with a spur is meshed externally with the gear with a spur. A rotating cylinder 203 is connected to the outside of the rotating cylinder 203. A second motor 207 is fixedly connected to the outside of the rotating cylinder 203. A first bevel gear 206 is fixedly connected to the output end of the second motor 207. A rotating disk 211 is meshed with the outside of the first bevel gear 206. A clamping block 202 is slidably connected to the outside of the rotating disk 211. First, the tower cylinder 4 is placed into the clamping block 202. Then, the second motor 207 is started to make the first bevel gear 206 rotate. The first bevel gear 206 drives the rotating disk 211 to rotate. The rotation of the rotating disk 211 causes the clamping block 202 to move inward, thereby clamping the tower cylinder 4. Then, the third motor 210 is started to make the second bevel gear 208 rotate. The second bevel gear 208 drives the third bevel gear 212 to rotate, thereby causing the threaded rod 208 to move inward. 09 rotates, causing the support base 201 to move the tower 4 to a suitable position. Then, the motor 205 is started, causing the gear 204 to rotate. The gear 204 drives the rotating cylinder 203 to rotate, thus rotating the tower 4. A through hole is provided at the corresponding position of the base 1 and the threaded rod 209. The threaded rod 209 is rotatably connected to the through hole of the base 1. Because the corresponding position of the base 1 and the threaded rod 209 has a through hole and the threaded rod 209 is rotatably connected to the through hole of the base 1, the rotation of the threaded rod 209 can move the support base 201, allowing the two towers 4 to be connected, which is beneficial for the preheating and welding of the towers 4. A through hole is provided at the corresponding position of the rotating cylinder 203 and the clamping block 202. 02 is slidably connected in the through hole of the rotating cylinder 203. Because the rotating cylinder 203 and the clamping block 202 are provided with through holes at corresponding positions and the clamping block 202 is slidably connected in the through hole of the rotating cylinder 203, the clamping block 202 can move inward and outward, which is beneficial for the device to clamp tower cylinders 4 of different sizes; the support base 201 and the rotating cylinder 203 are provided with through holes at corresponding positions and the rotating cylinder 203 is rotatably connected in the through hole of the support base 201. Because the support base 201 and the rotating cylinder 203 are provided with through holes at corresponding positions and the rotating cylinder 203 is rotatably connected in the through hole of the support base 201, the rotating cylinder 203 carries the tower cylinder 4 to rotate, which is beneficial for more uniform preheating of the tower cylinder 4 and for welding of the tower cylinder 4;Three sets of bevel gears 206 are arranged in a circular array outside the rotating disk 211. This arrangement makes rotating the disk 211 easier and facilitates the inward and outward movement of the clamping block 202.

[0021] Please see Figure 4 In this embodiment, the preheating component includes a motor 33, which is fixedly connected to the outside of the base 1. The output end of the motor 33 is fixedly connected to a threaded rod 32. The external thread of the threaded rod 32 is threadedly connected to a support frame 31. A sliding rod 34 is slidably connected inside the support frame 31. A support ring 35 is fixedly connected to the top of the support frame 31. A flamethrower 36 is fixedly connected inside the support ring 35. By starting the motor 33, the threaded rod 32 is rotated, which drives the support frame 31 to the position to be preheated, so that the support ring 35 is aligned with the tower 4. Then, the flamethrower 36 is started to preheat the tower 4. A through hole is opened at the corresponding position of the base 1 and the sliding rod 34. The sliding rod 34 is rotatably connected in the through hole of the base 1. Because the corresponding position of the base 1 and the sliding rod 34 is opened with a through hole and the sliding rod 34 is rotatably connected in the through hole of the base 1, the support frame 31 can be moved, so that the preheating component can be moved to a suitable position.

[0022] During operation, the tower 4 is first placed into the clamping block 202. Then, the second motor 207 is started to rotate the first bevel gear 206. The first bevel gear 206 drives the rotating disk 211 to rotate. The rotation of the rotating disk 211 causes the clamping block 202 to move inward, thereby clamping the tower 4. Then, the third motor 210 is started to rotate the second bevel gear 208. The second bevel gear 208 drives the third bevel gear 212 to rotate, thereby rotating the first threaded rod 209. This moves the support base 201 with the tower 4 to the appropriate position. Then, the first motor 205 is started to rotate the column gear 204. The column gear 204 drives the rotating cylinder 203 to rotate, thereby rotating the tower 4. Then, the fourth motor 33 is started to rotate the second threaded rod 32. The second threaded rod 32 moves the support frame 31 to the position to be preheated, aligning the support ring 35 with the tower 4. Finally, the flamethrower 36 is started to preheat the tower 4.

[0023] Through the above steps, the tower cylinder 4 is first placed into the clamping block 202. Then, the second motor 207 is started to rotate the first bevel gear 206. The first bevel gear 206 drives the rotating disk 211 to rotate. The rotation of the rotating disk 211 causes the clamping block 202 to move inward, thereby clamping the tower cylinder 4. Then, the third motor 210 is started to rotate the second bevel gear 208. The second bevel gear 208 drives the third bevel gear 212 to rotate, thereby rotating the first threaded rod 209. This moves the support base 201 with the tower cylinder 4 to a suitable position. Then, the first motor 205 is started to rotate the cylindrical gear 204. The cylindrical gear 204 drives the rotating cylinder 203 to rotate, thereby rotating the tower cylinder 4. This solves the problem that the tower cylinder 4 may fall off if it is not properly restrained.
