Description

Technical Field

[0001] The present invention relates to the technical field of electric power tower welding, 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 support 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, and in the process of producing the steel pipe poles in the power tower, they need to be welded.

[0004] For example, the existing invention discloses "a large-caliber gantry submerged arc welding production line for manufacturing power towers", with the publication number "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 multiple groups are provided. The guide rail 3 is provided 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 undercuts. However, the impact resistance test of steel pipes and rods is particularly lacking. This makes it impossible to determine whether the steel pipes and rods after welding meet the impact resistance requirements. At the same time, it is impossible to sort out the bent or unbent steel pipes and rods after the impact resistance test.

[0005] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing automatic welding production line of power towers. Even if it can be solved, it needs to be solved with the cooperation of external tools, which makes it impossible to achieve the desired effect.

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 pressing assembly.

When the inserted rod is disengaged from the slot, it moves rapidly 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.

[0024] The present invention utilizes a sorting mechanism.

The rotation of the rotating column drives the pushing plate to rotate, and the rotation of the pushing plate drives the third conveying component to shift, thereby prompting the steel pipe rod that is bent after the knocking test to move to one side of the support plate for storage.

One side of the telescopic plate 2208 passes through one side of the support plate 2202, and one side of the inner cavity of the telescopic plate 2208 is movably connected to a roller 2224. The surface of the roller 2224 is in contact with one side of the movable plate 2203, and the inner wall of the groove 2215 is fixedly connected to a spring 222 5. There are two springs 2225, and one end of each of the two springs 2225 is fixedly connected to one side of the telescopic plate 2208. The setting of the groove 2215 guides the movement of the telescopic plate 2208, so that the telescopic plate 2208 can slide smoothly into the interior of the support plate 2202. At the same time, the setting of the roller 2224 reduces the friction between the movable plate 2203 and the telescopic plate 2208, ensuring the smooth rotation of the movable plate 2203 and avoiding damage to the telescopic plate 2208.

[0047] The interiors of the two springs 2225 are both movably connected to the outer rod 2214, one side of the outer rod 2214 is fixedly connected to the inner wall of the groove 2215, and the interior of the outer rod 2214 is movably connected to the inner rod 2220, and the inner rod 2220 is movably connected to the inner ring 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 deflecting when it is deformed.

[0048] The specific implementation of this embodiment is as follows: when the steel pipe rod that has been detected by knocking is not in 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 that has been detected by knocking is in a bent state, the bent steel pipe rod will push the movable plate 2203 to rotate. The rotation of the movable plate 2203 causes the telescopic plate 2208 to slide into the interior of the groove 2215. The movement of the telescopic plate 2208 drives the support plate 2202 to slide into the interior of the outer rod 2214. At the same time, the movement of the telescopic plate 2208 compresses and deforms the spring 2225. When the movable plate 2203 rotates, it drives the rotating column 2223 to rotate inside the baffle 2201. The rotation of the rotating column 2223 causes the torsion spring 2221 to deform. 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 pushing wheel 2217 to fit the surface of the steel pipe rod, thereby reducing the friction between the steel pipe rod and the pushing plate 2216. At the same time, the rotation of the pushing plate 2216 causes the rotating shaft 2218 to move, and the pushing sleeve 2219 will rotate on the surface of the rotating shaft 2218 and slide on the surface of the pushing column 2212. As the pushing plate 2216 rotates, the third transmission component 2205 will be 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 deviation 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, under the action of the third transmission component 2205 and the conveying component 2206, the steel pipe rod that is in a bent state when knocking detection is placed from a notch on one side of the moving plate 2203 to one side of the support plate 2202 for storage.

First, one of the steel pipe rods is transported to the surface of the second conveying assembly (17) by the first conveying assembly (14), and the steel pipe rod is compacted by one of the compacting assemblies (15). Then, the other steel pipe rod is transported to one side of the clamping assembly (13) by the first conveying assembly (14) and the second conveying assembly (17), and the steel pipe rod is compacted by another compacting assembly (15).

After welding, the cooling assembly (18) cools down the welding part of the steel pipe rod. After cooling, the steel pipe rod is transported to the inside of the grinding assembly (110) through the cooperation of the first conveying assembly (14) and the second conveying assembly (17), and the other end is located on the surface of the third conveying assembly (2205).
