Double-flanging special-shaped channel steel

Abstract

The invention relates to double-flanging special-shaped channel steel. The channel steel comprises a channel steel main body, the channel steel main body is integrally formed, is integrally arranged in a C shape and comprises an upper leg, an upper flanging, a lower leg, a lower flanging and a connecting part, the connecting part is arranged in the vertical direction, the upper leg is arranged in the horizontal direction, one end of the upper leg is arranged at the upper end of the connecting part, and the other end is provided with the upper flanging. The upper flanging is parallel to the connecting part, and the upper flanging and the connecting part are located at the two sides of the upper leg respectively. The channel steel has the advantages that the bearing strength of the channel steel main body is improved, surface contact stress of guide wheels and the channel steel main body is achieved, radial force capable of being borne by the upper leg and the lower leg of the channel steel main body is increased, the guide performance of the channel steel is enhanced, and the service life of the channel steel is prolonged. Meanwhile, abrasion of the guide wheels is reduced, the service life of the guide wheels is prolonged, and the running stability of a trolley in a rail is guaranteed.

Description

technical field [0001] The invention relates to a special-shaped channel steel with double flanging, and relates to conveying equipment for metallurgical iron and steel high-speed wire rod, automobile assembly, electrolytic aluminum and household appliance industry conveying line systems, and in particular to the bearing rail of the conveying equipment. Background technique [0002] The load-bearing rails of each conveyor line system play an important role in the conveying process. The profiles used for the load-bearing rails are all ordinary standard channel steels, but there are a series of problems in this channel steel, such as low strength and poor guidance, especially when turning. Severe wear and jamming causes a series of problems in the conveying process, which not only affects the conveying process, but also affects the subsequent processing speed and the working efficiency of the entire conveying system, reducing production capacity and increasing production cost...

AI Technical Summary

Problems solved by technology

At present, the bearing rails on the market are made of ordinary channel steel, and the trolley is designed with a single guide wheel. Since the contact area between the track and the trolley guide wheel is small, it can be simply understood as a line contact between the rail and the trolley guide wheel, especially for curved rails. The greater radial force bears, resulting in faster wear of the lower leg of the channel steel and the guide wheel, and the increased frequency of trolley jamming, which greatly shortens the service life of the track and the guide wheel of the trolley, and affects the working efficiency of the entire conveying system

Later, in order to decompose and reduce the radial force on the lower leg of the channel steel and increase the service life of the track channel steel, the trolley was changed from the initial single guide wheel design to the double guide wheel design. The radial force borne by the channel steel is jointly borne by the upper and lower legs of the channel steel. Although the radial force of a single leg is reduced and the service life of the channel steel is relatively improved, this solution only treats the symptoms but not the root cause, and the guide wheels and the channel steel remain the same For line contact, long-term use still cannot get rid of the problem of serious wear of guide wheels and channel steel

[0005] Channel steel is an important component of the bearing track system of wire conveying equipment. Due to the bearing capacity and guiding performance of channel steel, problems such as jamming and deformation of the track often occur, which seriously affect normal production. Based on the disadvantages of the existing technology, and Developed double-flanged special-shaped channel steel
