Description

Technical Field

[0001] The invention relates to the technical field of electric power tower welding, and in particular to an automatic welding production line for electric power towers and a welding process thereof. Background Art

[0002] Welding equipment refers to the equipment required to implement the welding process. Welding equipment includes welding machines, welding process equipment and welding auxiliary devices.

[0003] The power tower is the supporting point of the overhead line. If one circuit is erected on the power tower, it is a single-circuit transmission tower. If two circuits are erected on the power tower, it is a double-circuit transmission tower. In the production and processing of the power tower, steel pipe poles are needed for construction. In the process of producing the steel pipe poles in the power tower, welding work is required.

[0004] For example, the prior invention discloses "a large-caliber gantry submerged arc welding production line for manufacturing power iron towers", and its announcement number is "CN114433985A". The application includes a push assembly 1, a lifting assembly 2 and a guide rail 3. The push assembly 1 and the lifting assembly 2 are arranged in a staggered manner and are provided in multiple groups. The guide rail 3 is arranged at the front and rear sides of the push assembly 1 and the lifting assembly 2, and a submerged arc welding assembly is movably provided on the guide rail 3. After welding, the welding production line often needs to grind the welding position of the steel pipe rod to remove the welding The oxide layer and dirt on the surface make the weld joint tighter. At the same time, the inspection after welding is also particularly important. The general inspection method is to inspect the condition of the weld surface to check whether there are cracks, slag inclusions, pores, incomplete penetration, incomplete fusion, incomplete filling and visible undercut defects. However, the impact resistance test of steel pipes is particularly lacking, which makes it impossible to judge whether the steel pipes after welding meet the impact resistance requirements. At the same time, it is impossible to sort the bent or unbent steel pipes after the impact resistance test.

[0016] A welding process for an automatic welding production line for an electric power tower, the welding process also includes the following steps: A. First, one of the steel pipe rods is transported to the surface of the second conveying assembly by the first conveying assembly, and the steel pipe rod is compacted by one of the clamping assemblies. Then, the other steel pipe rod is transported to one side of the clamping assembly by the first conveying assembly and the second conveying assembly, and the steel pipe rod is compacted by another clamping assembly. Then, the welding assembly on the top of the X-axis slide table is lowered to the surface of the steel pipe rod, and the steel pipe rod is rotated and clamped by the clamping assembly, so as to realize the welding of the steel pipe rod. After welding, the cooling assembly cools the welding part of the steel pipe rod. After cooling, the steel pipe rod is transported to the inside of the grinding assembly through the cooperation of the first conveying assembly and the second conveying assembly, and the other end is located on the surface of the third conveying assembly. Then, the welding slag at the welding part is polished by the grinding assembly; B. The polished steel pipe rod is continuously transported backward by the second conveying assembly until one of the steel pipe rods is located at the top of the third conveying assembly, and the other steel pipe rod is suspended at the rear side of the third conveying assembly. At the same time, the conveying assembly is pushed downward by adjusting the cylinder and the steel pipe rod is pressed.

The rotation of the winding wheel winds up the connecting rope. At this time, the connecting rope will pull the sliding seat to move upward, and the spring will be compressed and deformed through the movement of the sliding seat. At the same time, the movement of the sliding seat causes the knocking head to move upward and be in a force storage state. When the inserted rod is disengaged from the slot, it quickly moves downward under the action of the spring to recover its deformation and the gravity of the knocking head itself, and the knocking head knocks on the surface of the steel pipe rod for detection. The present invention utilizes a sorting mechanism. If the steel pipe rod is bent during the knocking test, the movable plate will be pushed to move during the conveying process.

At the same time, the setting of the pushing column 2212 realizes the effect of force transmission, and then when the pushing plate 2216 rotates, it can push the third transmission component 2205 to translate.

[0030] One side of the baffle 2201 is fixedly connected with a connecting plate 2207, one side of the connecting plate 2207 is installed with a supporting plate 2202 by bolts, a groove 2215 is provided inside the supporting plate 2202, a telescopic plate 2208 is movably connected inside the groove 2215, one side of the telescopic plate 2208 penetrates to one side of the supporting plate 2202, one side of the inner cavity of the telescopic plate 2208 is movably connected with a roller 2224, the surface of the roller 2224 is in contact with one side of the moving plate 2203, and a spring 2224 is fixedly connected to the inner wall of the groove 2215. 5. There are two springs 2225, and one end of the two springs 2225 is fixedly connected to one side of the telescopic plate 2208. The setting of the groove 2215 guides the moving position of the telescopic plate 2208, so that the telescopic plate 2208 can smoothly slide into the interior of the support plate 2202. At the same time, the setting of the roller 2224 reduces the friction between the moving plate 2203 and the telescopic plate 2208, ensuring the smooth rotation of the moving plate 2203 and avoiding the damage of the telescopic plate 2208.

[0031] The two springs 2225 are both movably connected to the outer rod 2214 inside, one side of the outer rod 2214 is fixedly connected to the inner wall of the groove 2215, the inner rod 2220 is movably connected inside the outer rod 2214, the inner rod 2220 is movably connected to the inner circle of the spring 2225, and one side of the inner rod 2220 is fixedly connected to one side of the telescopic plate 2208; through the setting of the outer rod 2214, the inner rod 2220 can be stored, and at the same time, the setting of the inner rod 2220 and the outer rod 2214 supports the position of the spring 2225 to prevent the spring 2225 from deviating when deformation occurs.

[0032] The specific implementation of this embodiment is as follows: when the steel pipe rod detected by knocking does not show a bent state, the steel pipe rod will be smoothly transported to one side of the baffle 2201 for storage through the third transmission component 2205 and the conveying component 2206; when the steel pipe rod detected by knocking shows a bent state, the bent steel pipe rod will push the movable plate 2203 to rotate, and the rotation of the movable plate 2203 causes the telescopic plate 2208 to slide into the interior of the groove 2215, and the movement of the telescopic plate 2208 drives the support plate 2202 to slide into the interior of the outer rod 2214, and at the same time, the movement of the telescopic plate 2208 causes the spring 2225 to be compressed and deformed, and the rotation of the movable plate 2203 will drive the rotating column 2223 to rotate inside the baffle 2201, and the rotation of the rotating column 2223 causes the torsion spring 2221 to be deformed, and at the same time, the rotation of the rotating column 2223 drives the pushing plate 2216 to rotate The rotation of the push plate 2216 drives the push wheel 2217 to fit the surface of the steel pipe rod, thereby reducing the friction between the steel pipe rod and the push plate 2216. At the same time, the rotation of the push plate 2216 causes the rotating shaft 2218 to move, and the push sleeve 2219 rotates on the surface of the rotating shaft 2218 and slides on the surface of the push column 2212. As the push plate 2216 rotates, the third transmission component 2205 is pushed to deviate, and the movement of the third transmission component 2205 drives the guide pulley 2210 to slide inside the guide groove 2209. The displacement of the third transmission component 2205 drives the steel pipe rod to deviate. When the steel pipe rod moves to the other side of the moving plate 2203, the third transmission component 2205 and the conveying component 2206 make the steel pipe rod in a bent state during the knocking detection be disposed from a notch on one side of the moving plate 2203 to one side of the support plate 2202 for storage.
