Description

TECHNICAL FIELD

[0001] The present application is a transportation or storage device, and relates to the field of stereoscopic storage technology, and more particularly to an angle steel tower angle steel intelligent storage system. BACKGROUND

[0002] The angle steel tower angle steel is a core steel member for manufacturing an angle steel tower, also commonly known as angle iron, belongs to the category of hot-rolled steel, is mainly made of low-carbon steel or low-alloy steel through rolling processing, has an L-shaped cross section, and is divided into two specifications of equilateral angle steel and unequal angle steel. The angle steel tower angle steel is combined through welding, bolt connection and other processes to form key structural parts of the tower body, cross arm and inclined brace of the angle steel tower, has excellent bending, shearing and compressive mechanical properties, can effectively bear various forces such as wind load, ice and snow load, equipment dead weight and external construction load, and has the characteristics of light weight, convenient processing and installation, and relatively low material cost, thereby becoming the core material of angle steel tower structures such as power transmission line towers, communication base station towers, radio and television towers and lightning protection towers, and is widely used in the field of infrastructure construction of power, communication, radio and television and other fields.

[0003] At present, there are mainly two ways for the storage of angle steel. The first way is to directly place the angle steel on the ground of the factory building. Although this operation is simple, the angle steel is prone to rust due to ground moisture erosion, and a large area of the ground needs to be leveled, resulting in low space utilization. The second way is to use a special angle steel shelf or a stackable steel rack. The angle steel is classified by specifications and horizontally stacked. The shelf or rack is placed by forklifts or cranes. This way significantly improves the space utilization and effectively prevents moisture and rust, and is the mainstream choice of modern storage.

[0004] However, for long angle steel (length ≥ 6 meters), during the process of moving the stacked long angle steel to the storage steel rack, if a forklift is used for transfer, because the effective support length of the forklift fork is much smaller than the body length of the long angle steel, only the local area of the long angle steel can be supported, which is prone to permanent bending deformation of the long angle steel due to its own weight. In addition, when the forklift is operating, the two ends of the long angle steel will swing greatly with the movement of the vehicle body, which not only easily causes damage to the surface of the angle steel by colliding with surrounding facilities such as storage steel racks and walls, but also poses a safety hazard to the operator.

[0005] If a crane or gantry crane is used for transfer, although it can realize the vertical lifting and large-range moving of the long angle steel, the operation range of such equipment is strictly limited by the lifting track in the factory building, and cannot cover all the steel rack points in the storage area, which has poor operation flexibility. In addition, the long angle steel is prone to swinging like a pendulum during lifting, which may cause collision and damage. It is difficult to accurately align the support slots of the storage steel rack, which prolongs the operation time of the transfer and increases the risk of imbalance and sliding of the stacked body.
