Centering device used during guide rail conveying

Abstract

The invention discloses a centering device used during guide rail conveying. The centering device comprises a fixed base, a first swing arm, a second swing arm, a telescopic drive device and guide rollers; the rear end of the first swing arm and the rear end of the second swing arm are each provided with a first rotating shaft pointing to the fixed base downwards, and are each provided with a second rotating shaft pointing to the upper portion, the guide rollers are arranged on the second rotating shafts, and the first rotating shafts are correspondingly sleeved with gears; and through the manner, according to the centering device used during guide rail conveying, the telescopic drive device carries out telescopic operation to drive the first swing arm or the second swing arm to swing, meanwhile, the first swing arm and the second swing arm are engaged through the gears to synchronously move, the included angle between the first swing arm and the second swing arm is changed, the distance between the two guide rollers is changed also, the centering device is suitable for guide rails of different widths, before the guide rails are centered, the distance between two guide rollers is increased, and impact of the guide rails is avoided.

Description

technical field [0001] The invention relates to the field of guide rail production, in particular to a centering device during guide rail transportation. Background technique [0002] The comparison method of the application of T-shaped steel guide rails in elevators. Since the running accuracy and stability of elevators are greatly affected by T-shaped steel guide rails, the processing accuracy of T-shaped steel guide rails is required to be high. [0003] Both sides of the T-shaped steel guide rail need to be processed by a planer, and the end of the T-shaped steel guide rail also needs to be processed with male and female tenons. During the process of multiple processing and inspections, the transportation, transfer and positioning of the T-shaped steel guide rail are required. There is usually no centering device in the positioning process. Manual centering is time-consuming and labor-intensive, and the accuracy is poor. Even if some devices use mechanical centering devi...

AI Technical Summary

Problems solved by technology

There is usually no centering device in the positioning process. Manual centering is time-consuming and labor-intensive, and the accuracy is poor. Even if some devices use mechanical centering devices for positioning, due to the constant spacing of the mechanical centering device, it is difficult to adjust and the width adaptability is poor. Moreover, during the transportation process, the T-shaped steel guide rail is easy to collide with the mechanical centering device, resulting in collision damage
