Chained heavy rail spraying and transferring production line

Abstract

The invention discloses a chained heavy rail spraying and transferring production line which comprises chained steel moving mechanisms and a spraying device. Each chained steel moving mechanism comprises multiple sets of slide fastener machines, and each of the two ends of each slide fastener machine is provided with a ferry vehicle. Each slide fastener machine comprises a supporting beam, whereineach of the two ends of the supporting beam is provided with a ratchet wheel, and the ratchet wheels are engaged with a chain. Each chain comprises an inner chain plate, a heavy rail clamping groovechain plate, an inner chain plate and an outer chain plate which are connected end to end in sequence. Each ferry vehicle comprises a lifting frame, wherein a lifting hydraulic cylinder is installed at the bottom of the lifting frame, and a horizontal pushing mechanism is installed above the lifting frame. Each horizontal pushing mechanism comprises a horizontal stretching hydraulic cylinder and apush rod, wherein a heavy rail clamping groove is formed in the upper surface of the other end of the push rod, and a heavy rail is placed in the heavy rail clamping groove. By means of the chained heavy rail spraying and transferring production line, the ferry vehicles are used for transferring the heavy rails onto the slide fastener machines of the chained steel moving mechanisms, the heavy rail clamping grooves in the slide fastener machines are used for fixing, supporting and transferring the heavy rails, abrasion of heavy rail coatings is reduced, the coating quality of the heavy rails is improved, the occupied area is small, and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of heavy rail production, in particular to a chain-type heavy rail spraying and transporting production line. Background technique [0002] With the rapid development of China's high-speed rail transportation industry, the quality requirements for heavy rails are getting higher and higher. Performance indicators such as the anti-atmospheric corrosion rate and insulation rate of heavy rails for high-speed rails are constantly increasing. Corrosion or peeling of the rust layer occurs, and the rust water pollutes the railway track bed and the environment; at the same time, insulation between the heavy rail and the earth is required to ensure the stability of the high-speed rail signal during transmission and prevent stray current interference. [0003] The Chinese patent with authorized notification number CN207347857 discloses "A Fully Automatic High-speed Railway Ballastless Track Spraying Device", which uses...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a chain-type heavy rail spraying and transporting production line to solve the problems that the existing heavy rail production line is bulky, easily causes damage to the coating layer on the surface of the heavy rail, affects product quality, and has low production efficiency.
