Description

Technical Field

[0001] The utility model belongs to the technical field of handling equipment in the steel industry and relates to a device for handling H-shaped steel based on a horizontal clamping method. Background Art

[0002] At present, as a high-efficiency and economical profile with a scientific cross-sectional layout and a reasonable strength-to-weight ratio, H-shaped steel has excellent bending resistance in all directions. Therefore, it is widely used in some construction engineering fields such as high-rise buildings, industrial plants and large bridges. After the hot-rolled H-shaped steel completes the uniform cooling process, it needs to be transported to the straightening equipment and finishing area for a series of non-destructive straightening, cut to length, print marking and stacking and bundling processes. Production companies usually use lifting equipment in conjunction with slings to transport H-shaped steel. Since H-shaped steel will produce a certain degree of swing during the lifting process, this transportation method has a greater safety hazard.

[0003] After searching, we found that three patents are most relevant to the utility model technology. The specific contents are described as follows:

[0004] Patent document CN 205367084 U discloses an automatic clamping and handling device for steel sections. The device is primarily composed of a support column, an upper support plate, an extension plate, a gripping plate, a sliding track block, a sliding block, a connecting block, an adjustment block, a movable frame, a transmission screw, a push rod, and a cylinder. While the device is novel in concept and ingenious in design, it can rapidly handle steel sections with good safety. However, the device's structural design is relatively complex, resulting in a relatively high manufacturing cost.

[0005] Patent document CN 206437794 U discloses a construction steel transporter. The device primarily comprises a mounting frame, a mounting plate, a fixed plate, a support plate, rollers, pulleys, a movable block, a fixed block, an end block, a clamping block, a drive screw, a connecting rod, a telescopic rod, legs, a displacement motor, a hydraulic cylinder, and a control panel. While the device is novel in concept and ingenious in design, and capable of smoothly transporting steel sections with good safety, its structural design is relatively complex, resulting in a relatively high manufacturing cost.

[0006] Patent document CN 113844866 A discloses a steel section handling device. The patented device mainly consists of a transmission shaft, a rotating shaft, a handling arm, a transmission roller, a counterweight, a pallet, a sprocket, a chain, a bearing box and a tensioning eccentric mechanism. The device is novel in conception and ingenious in design. Although it can realize the transportation of steel sections of different specifications and has good safety, the device is based on a transport roller to achieve the handling task, which results in the device occupying a relatively large area. Therefore, the manufacturing cost of the device is relatively high. Utility Model Content
