Double-locking bar lubricator for electro-hydraulic switch machine

Abstract

The invention discloses a double-locking bar lubricator for an electro-hydraulic switch machine, which relates to the technical field of auxiliary devices for railway switches. According to the invention, the double-locking bar lubricator for the electro-hydraulic switch machine comprises an oil storage box with an upper cover, wherein a plurality of oil leaking holes are distributed in the bottom of the oil storage box; a sponge box, which is full of sponge and opened at the bottom, is arranged to stick to the lower surface of the oil storage box; two inverted U-shaped guide grooves, which can be matched with locking bars, are formed in the bottom of the front side plate and / or the rear side plate of the sponge box; and the bottoms of the inverted U-shaped guide grooves are higher than the lower surface of the sponge. The invention is advantaged in that the double-locking bar lubricator for the electro-hydraulic switch machine is simply structured, easy to make and convenient to use, the double-locking bar lubricator can automatically lubricate locking hooks in time and the working strengths and potential safety hazards of maintenance personnel are reduced.

Description

technical field [0001] The invention relates to the technical field of auxiliary devices of railway turnouts, in particular to an electrohydraulic switch machine double locking rod lubricator. Background technique [0002] As an important equipment for railway line connection, turnout is one of the weakest links in the track. With the development of railway transportation towards high-speed and heavy-duty direction, heavy rail and large-number turnouts are adopted, and electro-hydraulic switch machines have begun to be widely used. . ZY (ZYJ) 7 series electro-hydraulic switch machine and its supporting installation device and external locking device adopt double-rod locking point rails at the close-fitting position, which can effectively overcome the conversion resistance of the point rails when they are close-fitting, and are reliable. The ground locks the point rail and the basic rail of the switch, and the external locking device can isolate the vibration and impact on t...

Problems solved by technology

[0003] At present, on the existing speed-up turnouts of the railway, the movement and locking of the turnout is to rely on the locking plate to drive the lock hook, and use the lock hook to catch the locking frame to realize the locking of the turnout. It is realized by pushing and pulling the lock hook of the closing plate. Because the turnout is repeatedly pulled back and forth, the friction between the locking plate and the lock hook is very large, and it is easy to cause wear and tear. Therefore, it is required to regularly oil these friction parts of the outer lock of the turnout , so that it is always lubricated

At present, this kind of oiling work needs to be done manually. Due to the high traffic density, frequent turnout movements, and external weather changes and harsh environments, maintenance personnel need to use oiling guns or oil brushes to oil the turnouts almost every day, which greatly increases the burden on maintenance personnel. The work intensity is high, and there are still hidden dangers to personal safety. At the same time, due to untimely oiling and lubrication, it may also cause railway transportation failures
