Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of steel structure component manufacturing, and particularly relates to a conveying roller way for centering and splicing of steel structure components and a conveying method. BACKGROUND

[0002] Steel structure is usually composed of columns, beams, trusses, plates and other components made of steel plates and sections, and the parts are spliced by welding, riveting or bolt connection to form the main frame of the building. Compared with other material building structures, the advantages of steel structure building are: high strength, light structure weight, small self-weight under the same stress condition, large span structure can be built, and good seismic performance; due to the weldability of steel, the connection of steel structure is greatly simplified, which is suitable for manufacturing various complex structures; the manufacturing of steel structure components is mainly carried out in specialized metal component factories, which is convenient, high in precision, high in on-site assembly degree, and short in construction period.

[0003] Due to obvious advantages, steel structure has been widely used in large-span workshops, airports, high-rise buildings, bridges and other fields. Steel structure components have various types and categories, among which H-type and T-type components made of steel plate cutting, splicing and welding have the advantages of optimized cross-sectional area distribution, reasonable strength-to-weight ratio, strong bending resistance, simple construction, cost saving and the like, and have been widely used in steel structure buildings. Its production process has also changed from traditional manual steel plate cutting, splicing and welding to production by specialized equipment.

[0004] The main equipment for producing H-type and T-type components of steel structure includes: flame cutting equipment for cutting of plates, conveying roller way with righting function for righting, centering and conveying of cut plates, assembly equipment for splicing and positioning of plates according to certain type and precision requirements, welding equipment for welding of spliced plates, correcting equipment for correcting of welding deformation of components after welding, and output roller way for conveying of H-type or T-type components after correction. In some production plants, these equipment are relatively independent, and in some production plants, related equipment is integrated into an integrated "assembly-welding-correcting all-in-one machine". Whether it is a relatively independent production equipment or an integrated assembly-welding-correcting all-in-one machine, the conveying roller way with righting function is an indispensable equipment in the production process of components.

[0005] Both H-shaped and T-shaped members are composed of flanges and webs. The working process of the centering roller is that the cut flanges are first placed on the corresponding position of the roller by hoisting equipment, at this time the flanges are randomly placed on the roller and need to be centered in the width direction by the corresponding flange centering mechanism; on this basis, the cut web is hoisted and placed on the flange that has been centered by the hoisting equipment, at this time if the hoisting equipment is released, the web will be overturned to cause an accident, so before the hoisting equipment is released, the corresponding web centering mechanism is needed to center the web on the middle position above the flange, at this time the hoisting equipment is released and the flange and the web are placed on the conveying roller in the form of splicing under the support of the corresponding centering mechanism, and the conveying roller drives the spliced member to the next process through the power component.

[0006] Currently, the conveying roller that can be applied to the field of steel structure member manufacturing mainly has the following deficiencies:

[0007] 1) Most conveying rollers do not have flange centering and web centering functions, such as the H-shaped steel assembly machine steel structure member conveying device disclosed in Chinese patent CN214113780U and the conveying roller of the H-shaped steel assembly machine disclosed in Chinese patent CN208450954U, which makes it difficult to splice, center and convey each plate of the H-shaped and T-shaped members before entering the assembly welding;

[0008] 2) The H-shaped steel assembly and welding straightening composite machine disclosed in Chinese patent CN209578788U and the steel plate conveying roller of the straightening machine disclosed in Chinese patent CN104401640A have a centering and centering function, and the conveying roller structure process needs to be improved, the installation and maintenance are inconvenient, and the structure height of the centering and centering component is high, which increases the lifting height during the hoisting process of all plate materials, reduces the operation efficiency and safety, and increases the labor intensity;

[0009] 3) The centering mechanism of the conveying roller is mostly rigid structure, such as the conveying roller with adjustable limiting safety device disclosed in Chinese patent CN212023958U, and the pressure after the centering mechanism compresses the plate is not considered, such as the steel plate conveying roller with positioning clamp disclosed in Chinese patent CN213386484U, which mainly relies on manual observation of the contact between the centering mechanism and the plate and equipment debugging for different types of plates, if the operation is wrong, not only the plate will be deformed, but also the corresponding member will have the risk of fatigue failure;

[0010] 4) A conveying roller bed for a horizontal H-beam assembly machine as disclosed in Chinese Patent CN211991645U and a H-beam assembly and straightening composite machine as disclosed in Chinese Patent CN209578788U do not fully utilize sensing and detection technology and automatic control technology, have low automation degree, and require multiple people to work together in the plate assembly, centering, and conveying process, thereby increasing labor cost.
