Steel rail roller conveyer

Abstract

The invention discloses a steel rail roller conveyor. The main structure of the conveyor is that a motor is engaged with a gear fixed in the lower part of a transmission shaft inside a driving vertical roll cabinet through a retarder, a pair of gears fixed in the middle part of a stationary transmission shaft are engaged with each other and respectively engaged with two groups of intermediate gears, the intermediate gears are engaged with the gear in the middle part of a driving vertical roll to drive the rotation of the driving vertical roll, each intermediate gear is respectively engaged with a pivoted arm on the main shaft of the driving vertical roll and a pivot arm on the stationary transmission shaft, each main shaft of the driving vertical roll respectively forms a gear-link rod mechanism together with the stationary transmission shaft, and the four driving vertical roll cabinets are independent and have closed guide track structure. The inventive steel rail roller conveyor realizes the rotation of two pairs of driving vertical rolls for holding the rail web at the same rotation speed. The driving vertical rolls convey long steel rails to the 500-meter long steel rail storage platform along a roller line and then open to make room for hoisting the steel rails, so as to meet the technical requirements of driving the steel rails to travel along the roller line of the 500-meter long steel rail storage platform.

Description

technical field [0001] The invention relates to a rail roller conveyor, in particular to a rail roller conveyor which is specially used for driving the rail roller in a railway fixed-length rail welding production line. Background technique [0002] At present, the structure of the existing rail roller conveyor is that the reducer rotates the lower horizontal drive roller, which is driven by friction with the rail bottom; the rail head has an upper horizontal roller that can swing or move, and the upper horizontal roller is driven by air pressure or hydraulic pressure. The roller is pressed on the head of the rail to increase the friction between the lower horizontal driving roller and the bottom of the rail to realize the driving of the rail roller table in the rail welding production line. The problem with this construction is that when the rail needs to be hoisted off the roller table line, the horizontal rollers pressing on the head of the rail must be moved away. If th...

AI Technical Summary

Problems solved by technology

The problem with this structure is that when the rail needs to be lifted off the roller table line, the horizontal rollers pressing on the head of the rail must be removed

However, this structure is more complex and bulky, which reduces the area of ​​the 500-meter long rail storage platform for storing rails, and has a relatively large defect in the use of the 500-meter long rail storage platform.
