Abstract

PURPOSE:To make it possible to determine a load generated at various parts of a switch lock unit during the switching of a point rail of a diverging junction and an impact load during the passage of rail vehicles by properly changing connection pins of the lock unif for a railway diverging junction. CONSTITUTION:A steel material with a proper strength is worked into a connection pin. The leg section thereof is divided into three detection sections... an upper level contact detection section 15, a medium level contact detection section 17 and a lower level contact detection section 16. Strain gauges 18 are applied into recesses provided between upper and medium level contact detection sections 15 and 17 and medium and lower level contact detection sections 17 and 16. After a conventional connection pin connecting a working rod 4 and a point rod 5 is pulled out, a connection pin type axial force detector body 14 is inserted and a split pin is inserted in a hole 21 to prevent the slipping of the detector body 14. The load can be detected easily with a strain gauge 18 after the top of a pin hole for connecting forked rod of the point rod 5 is brought into contact with the upper level contact detection section 15, the bottom of the pin hole with the lower level contact detector section 16 and a connection pin hole of the working rod 4 with the medium level contact detection section 17.
