DEVICE FOR SIMULATING PROCESS OF VERTICAL LOADING AND REMOVAL OF LOADING CHARACTERISTIC OF POINT JACKING DEVICE OF ROLLING STOCK FIXING ON SORTING TRACKS OF STATIONS

摘要

FIELD: measuring equipment.;SUBSTANCE: invention relates to measurement equipment, in particular, to devices for mechanical determination of movement resistance of stock of point-type jacking device for fastening of rolling stock on sorting tracks of stations under load and construction of load characteristic of analysed point jack-like device. Device comprises housing with hydraulic jack installed in it, position sensor, force-measuring device. Body is made in the form of bracket, lower end of which is shorter than upper one and is configured to rest in lower surface of rail head and in upper surface of rail foot. On the upper end of the bracket two additional attachment arms are installed by means of hinges, one on each side of the upper end of the bracket, with the possibility of their resting in the lower surface of the rail foot and further fixation by wedge-shaped retainers. Additional arms of fixation are connected to each other by bridge, on which movable L-shaped support is installed to fix movement of head of point jack-like device, consisting of rod with graduating and transverse cantilever, to support transverse cantilever in lower part of head of point jacking device. On the inner side of the upper end of the bracket there is a slot in which a mechanical dynamometer is installed to fix the force of action on the head of the point jack-like device resting on the horizontal surface of the slot, and hydraulic jack connected with hydraulic pump with mechanical time counter to fix time of action on head of point jacking device. One side of the hydraulic jack is supported by a mechanical dynamometer, and the other side is made with possibility of contact with the head of the point jack-like device. To analyse fixed values of movement, action force and exposure time, a tablet with three movable rails is intended.;EFFECT: possibility of simulating the process of vertical loading of the stock of the jacking device of fastening of rolling stock on sorting tracks of stations, as well as obtaining data on loading, movement and loading time.;1 cl, 3 dwg
