Full Text This invention relates to a switch setting device for turn outs in the railways track.
Switches are provided at the turn outs in the railway tracks. Thick web/thin web switches with a big diaversing radius automatically has longer switch rails to meet the requirement of high speed trains. These switches are unstable in their back contact areas which causes floating tight gauge and do not provide adequate flange way clearance in their open position for the wheel of running train. Due to this inadequate flangeway clearance every wheel of a passing train hits the switch rail at JOH (Junction of Rail Heads) and cause rattling of switch rail. This hitting of wheel flange at JOH not only cause rubbing of tongue rail but also at the same time proper riding of the wheel over the turnout to pass it on prescribed speed is also not available.
Therefore a switch setting device is provided in the known art for use of turn outs of the railway-tracks. The device comprises a spring loaded
connector for connecting right angle cranks provided at both the sides thereof. The other ends of the right angle cranks are connected to the connecting rods which are adapted to be connected with respective rails of the switch at both sides. When any connecting rod is pushed/pulled at the stroke/opening of 160 mm, only then the right angle crank on the other side is pushed towards the rail of the switch by means of spring loaded connector so as to provide a minimum gap between the rails of the switch at the opposite side and its use is limited to thick web switches having 145 to 160 mm opening at toe only.
There are disadvantages associated with the setting device of the prior art. One of the main disadvantage is that the device has a single spring which breaks very oftenly and the device becomes useless.
Another disadvantage is that the device known in the art can not be used for thin web switches having 95 to 160 mm opening at toe and also for thick web switches having 95 to 1.45 mm opening at toe operated with electric point machine.
Another disadvantage is that the device can not be used for thin/thick web switches operated manually having 95 to 160/145 mm opening at toe.
Another disadvantage is that the device known in the art is to be fitted in the centre of the track and therefore it is damaged due to loose/hanging coupling of the moving train.
Another disadvantage is that device known in the art is operable at the stroke of 145-160 mm for thick web switches only and cam not be used for thin web switches only.
Therefore the main object of this invention is to provide a novel spring operated switch setting device for turn outs in the railway tracks.
Another object of this invention is to provide a switch setting device having a pair of springs and if one spring is broken even then the device works.
Yet another object of this invention is that the device is capable for setting the switches at the stroke/opening at toe of 95 to 145 mm for thick web switches and 95 mm to 16 mm for thin web switches.
Still another object of this invention is to provide switch -setting device adapted to be flitted off centre on the track to avoid damage due to loose/hanging coupling of the running train.
A further object of this invention is to provide a switch setting device which is capable to be used with thin web switch as well as thick web switch of the stroke of 95 to 160/145 mm at toe operated with electric point machine.
A further another object of this invention is to provide switch setting device which is capable to be used with thin/thick web switches operated manually having 95 to 160/145 mm opening at toe.
