DEVICE FOR DETERMINING VALUE OF RESISTANCE COEFFICIENT TO MINE TROLLEY MOVEMENT Russian patent published in 2015 - IPC G01M17/08 

FIELD: testing technology.

SUBSTANCE: invention relates to testing of vehicles, in particular mine trolleys. The device comprises an inclined, in the test operating part of the track way with a fixed angle of its inclination and the adjacent horizontal parts of the track way. The operating part of the track way is fastened to the frame with the possibility of its rotation in a vertical plane relative to the hinge assembly mounted on a support surface of the horizontal working, with adjoining of rails on the opposite sides to the track way of the working. The frame with the working part of the track way fixed on it is kinematically linked to the drive of its rotation made in the form of an electric-screw pusher which rod is pivotally connected to the frame, and its casing is pivotally mounted on the support surface of the working. At the side edge of the operating track way in front of the hinge assembly a vertical sector is placed with the images of lines oriented at angles to each other placed on it, with their vertex in the centre of the hinge assembly, with the values of the coefficients of resistance to movement of trolleys, imaged on the surface of the sector, corresponding to each angle of inclination of the lines in the sector. On the rotary frame from the side of the sector a horizontally oriented protrusion is fixed, located with a gap with respect to the semicircular outer edge of the sector at the level of rail heads of the working part of the track way, mounted on the rotary frame.

EFFECT: improving the process of assessment of running characteristics of a mine trolley.
