Description

TECHNICAL FIELD

[0002] The crane refers to the hoisting of heavy objects with hooks or other material taking devices, vertically lifting and horizontally transporting heavy objects in a certain range, also known as a crane, which belongs to the material handling machinery. The metal structure of the crane (such as the main beam, arm support, tower body, leg, etc.) is the core of carrying heavy objects, and welding is the main way to connect these structural parts into a whole. The welding quality defects (such as cracks, incomplete penetration, pores, etc.) may cause insufficient structural strength, leading to safety accidents such as fracture and collapse. Therefore, welding is regarded as a "lifeline" level process in crane manufacturing, which needs to meet the strict requirements of strength, toughness, fatigue performance and dimensional accuracy. Arc welding is suitable for repair, small batch or complex groove welding, and is mainly used for auxiliary welds of cranes or on-site repair.

[0035] High-pressure air pump 1002 draws air from the inside of the annular shell 1001, causing the gas surrounding the outside of the annular shell 1001 to enter the interior through the dust filter holes 1003. Multiple dust filter holes 1003 on the outside of the annular shell 1001 filter out fine welding slag and dust from the flue gas. The flue gas entering the annular shell 1001 comes into contact with the annular filter element 1007, is purified by the annular filter element 1007, and then exits from the high-pressure air pump 1002. The flue gas with particulate matter removed is further purified by installing the annular filter element 1007 inside the U-shaped slide bar 1005.

The arc-shaped scraper 1104 scrapes and cleans the outer surface of the rotating annular shell 1001. The bottom of the arc-shaped scraper 1104 is fixed to the top of the strip-shaped sleeve 1103 to stabilize the shape of the arc-shaped scraper 1104. As the top annular plate 7 rotates, the electric mechanical arm 8 rotates to contact the strip-shaped sleeve 1103. Upon contact, the push rod rotates around the fixed through rod 1106, causing the rotary spring 1102 to rotate and tighten. When the electric robotic arm 8 passes over the strip rod 1103, the strip rod 1103 loses its thrust. At this time, the rotary spring 1102 drives the strip rod 1103 to rotate back to the initial position tangent to the outer surface of the annular shell 1001 through the rotational force. The rotatable and reset strip rod 1103 is set between the bottom corner plate 1101 and the top circular plate 1105 to facilitate the rotation adjustment of the electric robotic arm 8 without affecting it. The fixed through rod 1106 is set between the bottom corner plate 1101 and the top circular plate 1105 to limit the elastically connected strip rod 1103. The annular electric slide rail 6 moves with the frame sleeve When plate 4 moves upward, it causes the bottom fixed corner block 1211 to move. When fixed corner block 1211 moves upward, it causes the convex sleeve plate 1209 on one side to move upward. As the fixed corner block 1211 moves upward, the convex sleeve plate 1209 rotates around the third inner rod 1208 and drives the second concave plate 1206 to move upward together through the third inner rod 1208. When the second concave plate 1206 moves upward, it drives the medium sleeve plate 1203 to move upward through the second inner rod 1207. By setting return springs 1204, 1205 and 1210 on both sides of the medium sleeve plate 1203 and the convex sleeve plate 1209 respectively, the medium sleeve plate 1203 and the convex sleeve plate 1209 are always in an unfolded trend to provide bottom support for the bottom of the annular electric slide rail 6.By setting convex sleeve plate 1209 and medium sleeve plate 1203 in first concave plate 1201 and second concave plate 1206, convex sleeve plate 1209 and medium sleeve plate 1203 can only rotate to vertical state at most, and when annular electric slide rail 6 moves down, convex sleeve plate 1209 and medium sleeve plate 1203 are pushed to fold mutually, and by setting foldable convex sleeve plate 1209 and medium sleeve plate 1203 between annular electric slide rail 6 and circular base plate 1, the bottom of annular electric slide rail 6 is always at a distance from one end of circular base plate 1.
