Railway track bolt automatic screwing and oiling trolley

Abstract

The invention discloses an automatic bolt screwing and lubricating wagon for railway rails. The automatic bolt screwing and lubricating wagon comprises a walking device, wherein a machine frame is arranged on the walking device; a bolt detecting sensor, a bolt screwing device and a bolt lubricating device are arranged on the machine frame; the bolt screwing device comprises a bearing platform; a screw rod vertical motion mechanism is arranged on the bearing platform; the bearing platform is in threaded connection with a screw rod of the screw rod vertical motion mechanism; one or more sets of X-Y adjusting platforms are movably connected to the bearing platform; a bolt screwing machine is connected to the lower ends of the adjusting platforms; and the bolt screwing machine comprises a bolt screwing driving motor, a torque controller and a bolt alignment guiding sleeve, which are sequentially arranged from top to bottom. Compared with a conventional bolt screwing device, the automatic bolt screwing and lubricating wagon disclosed by the invention is high in automation degree, so that human resources are saved, and the conservation efficiency of a railway is improved.

Description

technical field [0001] The invention relates to maintenance equipment for railway tracks, in particular to a trolley for automatic screwing and oiling of railway track bolts. Background technique [0002] In recent years, the development trend of national passenger railways is high speed, high density and heavy load. The frequency of failures of track connecting components is getting higher and higher, and the workload of maintenance is also increasing. It is the most important part in the daily maintenance of the track, and the inspection and tightening of the bolts are the most frequent. If the problem of bolt loosening cannot be solved in time, it will cause great harm to the operation safety of the vehicle. Due to the large amount of oiling work, the oiling work is closely related to the bolt fastening work, so the oiling work is also urgently needed to be completed by automated machinery. The failure of the track connection parts mainly refers to the defects such as l...

AI Technical Summary

Problems solved by technology

[0006] Although the wooden material used for the backing plate of the center plate has a higher friction coefficient than the steel backing plate, due to the insufficient compressive strength of the wooden backing plate, it is affected by natural shrinkage and static and dynamic loads of the car body. After a certain period of use, Misalignment or damage will occur, and the shrinkage of the wooden backing plate will cause the bolts to have no pre-tightening force, thus losing their self-locking properties and loosening

[0007] (3) Influence of working environment

The train itself contains a spring shock absorber, and its running stability is poor

When passing through rail joints and turnouts, the vibration, impact force, and vibration frequency are relatively high. When the nut is in this environment for a long time, it will loosen or even fall off.
