DEVICE FOR MECHANICAL METHOD OF PREPARATION OF SKATE-SKI-TRACK Russian patent published in 2015 - IPC E01H4/02 

FIELD: transportation.

SUBSTANCE: device for mechanical method of preparation of skate-ski-track for movement on skate-ski is offered. The draft device and the trailer device implemented with installation on it of the mechanism for preparation of skate-ski-track with a possibility of linear movement, in the coordinate plane X, contains the following: the bed implemented with a possibility of sliding on ice which has the devices for skate-ski-track preparation containing the mechanisms rotating at least two mills, for cutting of skate-ski-track profile, implemented with a possibility of the reverse vertical movement, in the plane of the coordinate axis Y are mounted, the mills are implemented with a possibility of the reverse cross movement, in the plane of the coordinate axis Z, with reference to the bed, and also with the automatic device providing control of the process required for preparation of the skate-ski-track as a result of the named above actions in general, and specifically the bed movements and the simultaneous cross reverse movement on it of the mills implemented with a possibility of rotation and reverse movement upwards, downwards, cutting of channel-like profiles of the skate-ski-track is provided, for movement on them with the known skate-ski strides. The trailer device is implemented with a possibility of processing of ice surface by the rotating grinding device installed instead of mills, and implemented with a possibility of formation of the ground ice for skating stride. The trailer device is implemented with a possibility of processing of ice surface by the rotating mills, forming, at least, of two channel-type tracks, for movement by the classical, neo-classical, sinusoidal, gaussoidal and gaussinusoidal strides, while its height, width and distance between them are selected depending on features of skate-ski design and anthropological possibilities of users, and also from the goal, tasks, temperatures of ice, air, weather conditions and the sliding surfaces of skate-ski. Mills for the classical and neo-classical strides are set permanently with reference to the bed. The cabin of the draft device is fitted with radio communication, external and internal lighting devices, the speedometer, and the device, drawing in paper the route profile, its length with level differences along the route. The trailer device is fitted with the device controlled by means of the computer device for marking of the skate-ski-track route, for example, with the paint of desirable colour; the projective distance (length) between the minimum points of curves in the cycle depends on the speed of movement of the bed and mills; projective minimum points of curves are on the track trajectory for movement by the classical stride; projective maximum points between two curves are marked depending on anthropological possibilities of users.

EFFECT: accuracy improvement, cost reduction.
