A anti-deflection mechanism for crossing the curve of the sand spreading device in the middle of the locomotive body

Abstract

The invention relates to a through curve deflection preventing mechanism of a sand spraying device in the middle of a locomotive car body. According to the constitution, the middle of a right (left) sand spraying hose of the sand spraying device in the middle of the car body is matched with a connecting hole in the lower end of a right (left) homodromous lever, the upper end of the right (left) homodromous lever is hinged to a right (left) stop lever, and the upper end of the right (left) stop lever is fixed on an end beam of a locomotive frame; the middle of the right (left) homodromous lever is hinged to the right (left) end of a right (left) sleeve, the middle of the right (left) sleeve is externally arranged in the inner cavity of a right (left) sleeve seat at the lower part of the end beam in a sleeving manner, and the part between the left end of the right (left) sleeve and the right (left) sleeve seat is provided with a right (left) sleeve reset spring in the sleeving manner; the inner cavity of the right (left) sleeve is sleeved with the right (left) end of a cross bar, the part, deviated to right (left), of the cross bar is provided with a right (left) front stop lever, and a right (left) stop lever reset spring is arranged between the right (left) front stop lever of the cross bar and the right (left) sleeve in the sleeving manner; the lower end of an upright tube connected with the car body is positioned in a space formed by the cross bar, the right front stop lever and the left front stop lever.

Description

technical field [0001] The invention relates to a curve-crossing anti-deflection mechanism for a sand-sprinkling device of a railway locomotive, in particular to a curve-crossing anti-deflection mechanism for a sand-sprinkling device in the middle of a locomotive car body. Background technique [0002] In the case of more rain and humid air, the adhesion coefficient between the locomotive wheels and the track decreases, and when the locomotive passes the track, the wheels are prone to slipping and idling; on the one hand, the traction force is insufficient or the braking force is insufficient; The friction becomes sliding friction, which increases the wear of the wheel and rail and reduces the life of the wheel and rail, especially when the radius curve is too small, the wear on the wheel rim is more serious. [0003] Four pairs of sanding devices are installed on the locomotive body. When the locomotive is running, the first pair of sanding devices at the front end of the c...

AI Technical Summary

Problems solved by technology

However, at present, the sand spreading devices in the middle of the locomotive body (the front end of the first bogie and the rear end of the second bogie) are all designed according to the straight track. The nozzle of the sanding hose in the middle of the body and its sanding device will deviate to the outside of the outer track, causing a large amount of sand to be sprinkled on the outer side of the outer track or the inner side of the inner track (based on the centerline of the inner and outer tracks). It cannot be well sprinkled on the rail surface, and cannot effectively improve the adhesion coefficient between the wheel and rail

When the locomotive equipped with the sand spreading device in the middle of the locomotive car body passes the curved track, especially the small radius curved track, the wheels will still slip, idling, lack of traction, and the phenomenon of wheel and rail wear
