Description

Technical Field

[0001] The utility model belongs to the technical field of angle steel straightening equipment, and in particular relates to a straightening device for angle steel components of an ultra-high voltage iron tower. Background Art

[0002] Angle steel is a type of steel, primarily made of carbon structural steel or low-alloy high-strength structural steel. There are two types of angle steel: equal-leg angle steel and unequal-leg angle steel. Equal-leg angle steel has two equal-length sides, forming an L-shaped cross-section with a 90° angle between the two sides. For example, a common equal-leg angle steel specification is ∠50×50×5, indicating that each side is 50mm long and 5mm thick. Unequal-leg angle steel has two unequal-length sides, also forming an L-shaped cross-section, also with a 90° angle between the two sides. For example, a specification like ∠100×80×8 indicates that the long side is 100mm, the short side is 80mm, and the thickness is 8mm. Angle steel is a key material in power towers, which support high-voltage transmission lines. Angle steel is bolted or welded together to form the tower's body and crossarms. It can withstand various external forces, including the weight of the power lines, wind loads, and ice loads, ensuring the safe and stable operation of the transmission lines.

[0003] Residual stresses are generated during the manufacturing process of angle steel, such as rolling and welding. Under normal circumstances, these residual stresses are in equilibrium. However, external factors, such as cutting and drilling, can disrupt this stress balance, releasing residual stresses and causing the angle steel to bend.

[0004] When angle steel is used for on-site processing, it is often bent. For bent angle steel, it is necessary to straighten the angle steel. To straighten the angle steel, a roller bed is usually used, but the roller bed is large in size and heavy, and is not easy to move. Using conventional clamps for straightening can only achieve maintaining the same straight line, and cannot achieve rotational correction. Rotational correction can effectively release the stress of the angle steel. Based on the above situation, the utility model hopes to provide a straightening device for angle steel components of ultra-high voltage towers. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A device for straightening angle steel components for ultra-high voltage (UHV) towers comprises a main table 1 and four straightening assemblies 2. The four straightening assemblies 2 are arranged in a straight line and fixed to the main table 1, with adjacent straightening assemblies 2 spaced equidistant from each other. Each straightening assembly 2 comprises a straightening seat 3, which is fixed to the main table 1. A rotatable straightening ring 4 is positioned in the center of the straightening seat 3. A movable angle 5 is positioned inside the straightening ring 4. An adjustment pin 6 is positioned at the top of the straightening ring 4. The movable angle 5 is fixedly connected to the adjustment pin 6, which is threaded through the straightening ring 3. The height of the movable angle 5 can be adjusted by rotating the adjustment pin 6. To facilitate rotation of the adjustment pin 6, a crossbar 7 is positioned at the top of the adjustment pin 6. An adjustment member 8 is positioned at the inner bottom of the straightening ring 3. The adjustment member 8, the adjustment pin 6, and the movable angle 5 are coaxially located. The adjustment member 8 comprises a fixed seat 9, which is fixed to the straightening ring 4. An adjustment seat 10 is positioned above the fixed seat 9, which is flexibly connected to the fixed seat 9. An adjustment column 11 is provided between the adjustment seat 10 and the fixed seat 9. The top of the adjustment column 11 is fixedly connected to the adjustment seat 10, and the bottom of the adjustment column 11 is movably connected to the fixed seat 9. The lower half of the adjustment column 11 is a worm. At the same time, a rotating pin 12 is provided on the fixed seat 10, and the rotating pin 12 is meshed with the lower half of the adjustment column 11. By rotating the pin 12, the height of the adjustment seat 10 can be adjusted. The lower bottom surface of the movable angle 5 is an L-shaped right-angled surface, and the upper top surface of the adjustment seat 10 is an L-shaped right-angled surface. By bringing the movable angle 5 close to the adjustment seat 10, the angle steel can be clamped and fixed. A long adjustment slot 13 is provided on the top of the correction seat 3, and the adjustment pin 6 passes through the long adjustment slot 13. The position of the long adjustment slot 13 is a reserved position for the adjustment pin 6 to swing left and right.

[0023] When using this device, lower all adjustment seats 10 to their lowest position, with the upper surfaces of the adjustment seats 10 aligned horizontally. At this point, introduce the angle steel to be corrected, placing the naturally bent angle steel on the adjustment seats 10. Next, rotate each adjustment pin 6 to gradually lower each movable angle 5, fixing the angle steel in its respective position. Adjust the height of each adjustment seat according to the bent position of the angle steel to correct the angle steel. During this process, the correction ring 4 can be rotated via the adjustment pin 6 to eliminate stress on the angle steel and improve correction efficiency.
