Abstract
Description
Claims (11)
- An apparatus for forming an in line sliding surface of a ski jump platform, comprising:a cable (3) extending along two parallel guide rails (2) disposed on both sides of the in line sliding surface of the ski jump platform;an in line unit (4) for traveling on the guide rails;a snow removing/pressing plate (5) disposed at a lower edge portion on a valley side of said in line unit (4) and adapted for removing excessive snow on the in line sliding surface and for pressing and smoothing the remaining snow on the in line sliding surface and for being raised and lowered;two rotating cutters (6) disposed at upper edge portions on a mountain side of said in line unit (4) and adapted for forming two parallel approach grooves (7) along the in line sliding surface to be pressed and smoothed;a rotating cutter driving unit for driving said rotating cutters (6) and an in line unit (4) driving force transmission unit (37, 38) disposed on said in line unit (4) and linked with said cable (3) for transmitting a drive force from said cable (3) to said in line unit (4) for traveling said in line unit (4) upward and downward along the in line sliding surface so as to form the in line sliding surface.
- The apparatus as set forth in claim 1, further comprising:a cutting edge (5b) and a press plate (5c) disposed at a lower edge portion of said snow removing/pressing plate (5); andan angle adjusting unit (40) for adjusting the pressure applied to said cutting edge and said press plate corresponding to the angle of said snow removing/pressing plate (5).
- The apparatus as set forth in claim 1 or 2,
wherein said snow removing/pressing plate (5) and said rotating cutters (6) have corresponding lifting units (10, 11) for raising and lowering said snow removing/pressing plate (5) and said rotating cutters (6) against the in line sliding surface. - The apparatus as set forth in one of claims 1 to 3, further comprising:
snow removing plates (31) disposed before and after wheels of said in line unit and adapted for removing snow on the guide rails. - Apparatus according to one of claims 1 to 3, further comprising:groove shaver holders (8) disposed at the lower edge portion of the in line unit (4), and adapted for being traveled in the same direction as the rotating cutters (6) and for being raised and lowered, the width of each of said groove shaver holders being larger than each of the approach grooves (7) formed by the rotating cutters (6), said groove shaver holders (8) being formed in a sled shape; andgroove shavers (9) secured to lower surfaces of said groove shaver holders, the width of each of said groove shavers being nearly the same as the width of each of the approach grooves (7) formed by the rotating cutters (6), said groove shavers having lattice shaped saw teeth.
- The apparatus as set forth in claim 5,
wherein said groove shaver holders are disposed at the lower edge portion of the in line unit (4) between the in line unit (4) and the snow removing/pressing plate (5). - The apparatus as set forth in claim 5 or 6,
wherein the groove shaver holders have a corresponding lifting unit (12) for raising and lowering the groove shaver holders (8) against the in line sliding surface. - The apparatus as set forth in one of claims 1 to 7, further comprising:wheels (13) disposed on the in line unit (4) and adapted for traveling the in line unit (4) on the guide rails (2); andsnow removing plates (31) disposed before and after the wheels (13) of said in line unit (4) and adapted for removing snow on the guide rails.
- A method for forming an in line sliding surface for a ski jump platform, comprising the steps of:disposing guide rails (2) on both sides of the in line sliding surface of the ski jump platform;travelling an in line unit (4) along the in line sliding surface, the in line unit having a snow removing/pressing plate (5) and rotating cutters (6), the snow removing/pressing plate (5) being adapted for removing excessive snow on the in line sliding surface and for pressing and smoothing the remaining snow on the in line sliding surface, the rotating cutters (6) being adapted for forming two parallel approach grooves (7) on the in line sliding surface to be pressed and smoothed;lowering the snow removing/pressing plate (5) and raising the rotating cutters (6) so as to remove and press the snow on the in line sliding surface in a step of travelling the in line unit (4) downward from a mountain side to a valley side; andraising the snow removing/pressing plate (5) and lowering the rotating cutters (6) so as to form the approach grooves (7) in a step of travelling the in line unit (4) upward from the valley side to the mountain side.
- The method as set forth in claim 9, further comprising the step of:
varying the angle of the snow removing/pressing plate so as to adjust the pressure applied to a cutting edge (5b) and a press plate (5c) disposed on the snow removing/pressing plate. - The method according to claim 8 or 9, wherein the in line unit further has groove shaver holders (8) with grave shavers, disposed at lower edge portions of the in line unit;
the method further comprising the steps of:raising the groove shaver holders in the step of traveling the in line unit (4) downward along the guide rails along the in line surface; and lowering the rotation cutters (6) and the groove shaver holders (8) in the step of traveling the in line unit (4) upward for forming approach grooves (7) along the in line sliding surface by the rotating cutters (6), and forpressing groove shoulder portions and groove bottom edge portions of the approach grooves (7) with the groove shaver holders, and forforming unsmoothed snow on approach groove bottom portions with the groove shavers (9).
