Definitions

  • the invention relates to a device for a ski jump for application an ice sheet according to the preamble of claim 1 and a corresponding procedure.
  • DE-A-198 43 901 describes a device for the preservation of Known snow.
  • This facility, a cooling mat system will For example, laid on the ski slopes in the snow to use the snow to cool a cooling sole and make it so durable.
  • the object of the invention is to provide a device for a ski jump Apply an ice sheet that is slip-resistant. This task is solved by the device defined in claim 1.
  • the facility is intended to be an ice sheet on a ski jump to apply, and that on a surface that as a start-up and Jump zone between an upper and a lower end of a Hill structure is formed.
  • the facility forms a cycle with a coolant and a heat transfer system for the above Surface.
  • the heat transfer system includes hose-like Cooling pipes and crossbars.
  • the cooling pipes that come in between the two ends Running direction straight or with slight curvatures next to each other are arranged, connect a distributor with a collector for that Coolant.
  • the crossbars are used as spacers and fasteners for the cooling tubes are formed.
  • the dependent claims 2 to 8 relate to advantageous embodiments the device according to the invention.
  • a method of operating the Device is the subject of claims 9 and 10.
  • FIG. 1 shows a system which consists of a device 1 according to the invention and a hill structure 10.
  • This ice sheet 120 comes with a Heat transfer system 11 manufactured, the part of a coolant circuit with a refrigeration system 6, a circulation pump 7 and one Line 8 for the coolant is.
  • the hill structure 10 comprises one Hill table 100 and a structure supporting the hill table 100, which is only indicated in the form of a support structure 102.
  • the heat transfer system 11 comprises tubular cooling tubes 2 and crossbars 3.
  • the tubes 2 have a Flexibility so that it fits well with the curved surface 101 of the Have the hill structure 10 adjusted.
  • the cooling tubes 2, which between the both ends of the hill structure 10 in the running direction - straight or with slight curvatures (for example wavy) - next to each other are arranged, connect a distributor 21 with a collector 22.
  • Ein Coolant is fed into the distributor 21 via a flow line 81 and led out of the collector 22 via a return line 82.
  • the flow and return lines 81 and 82 according to Tichelmann connected: feed left and exit right - or vice versa.
  • the crosspieces 3 are used as spacers and fasteners for the Cooling tubes 2 formed. They contain grooves 32 in which the tubes 2 from inserted and fixed at the top. Steel angle 4, instead of which also flexible Connections can be used, and fasteners 41 serve to Cross bars 3 to be firmly anchored in the hill table 100. By this connection secures the ice sheet 120 against slipping. Forces are absorbed by the crossbars 3 so that they slide off the ice sheet 120 and tearing of the tubes 2 due to in To be able to prevent tensile stresses acting in the direction of travel.
  • the Crosspieces 3 and their fastenings 4, 41 must be designed so that also additional tensions, for example in the event of a fall Athletes arise, can be intercepted.
  • the crosspieces 3 are on their top 30 with largely flat surfaces educated. On all of these areas or a large part of these areas are an elevation between adjacent grooves 32, in particular a tip 31 arranged. These elevations 31 are so strong that they have expected shear forces exerted by the ice sheet 120 will be able to record.
  • the elevations 31 are advantageously colored and although with a color that is clearly recognizable after storage in an ice layer is. The recognizability also depends on the thickness of the ice sheet 120 over the Cross bars 3 off, so that the extent of this thickness can be estimated.
  • FIG. 3 shows a section of a cross section through an ice sheet 120, the has been generated by the heat transfer system 11.
  • the ice sheet 120 can be on the cooled heat transfer system 11 with or without Snow and by spraying water.
  • Running or Slideways 12 for guiding skis are in the surface 121 of the fully formed ice sheet 120 milled. So that when milling the Sliding tracks 12, the cooling tubes are not damaged, the crossbars 3 formed so that their top surfaces 30 over the highest places the outer surfaces of the cooling tubes 2 used.
  • the heat transfer system 11 can in this way on the hill structure 10 are arranged that between its surface 101 and the Heat transfer system 11 room for a solidified Snow liner 110 remains.
  • the crossbars 3 are on this Snow liner 110 applied; or they will be at their bottom edges partially stored in layer 110.
  • An ice sheet 120 can also be used without Form snow liner 110.
  • the cooling tubes 2 are in a central area, which is between the extends upper and lower ends of the hill structure 10, in arranged largely constant intervals.
  • the distances can be in lateral edge areas be somewhat larger.
  • the distance is between measured the pipe axes.
  • the cooling tubes have a diameter d and have a distance constant a in the central area, which with respect to d is larger by a factor whose value is in a range between 1.5 and 4, preferably between 1.8 and 2.5 at 2.
  • the crossbars 3 are in Distances arranged in the running direction, which are much larger -10 to 100 Times larger than the distance constant a.
  • Fig. 4 shows a cooling tube register 20, which is a module of a multi-part Heat transfer system 11 is.
  • the ends of the cooling pipe register 20 are formed by a distributor piece 21a and a collector piece 22a. Start and end pieces with supply and return lines are shown 81, 82.
  • the arrows 81 'and 82' denote the flows of the supplied or coolant carried away.
  • the modules 20 can via coupling pieces 23 for Entire heat transfer system 11 are assembled.
  • the Distribution piece 21 a or collector piece 22a is a tube with a square Cross section shown. The cross section can of course also be one have a different shape, for example circular.
  • the width of the pipe register is preferably 2 m. Will be for the cooling tubes 2 Diameter d of 20 mm selected and for the distance constant a 40 mm, thus the pipe register comprises 50 pipes if these are equally spaced exhibit.
  • the heat transfer system 11 or the modules 20 of this system can be designed so that they are in the form of rollers 5 - see Fig. 6 - have it transported. Such roles 5, which together with a Stand 50 can be used as a rolling device, can be installed when the Heat transfer system 11 on the hill structure 10 of the latter be processed from the upper end.
  • Fig. 7 shows a cross section through a cooling tube 2, which is fastened in a crossbar 3.
  • the cooling pipe 2 must be able to withstand an internal pressure of up to 10 bar (10 6 Pa). It is therefore necessary to provide a reinforcement 221 for the tube wall 220, if plastic is used for its production, which is, for example, a braid of metal wires.
  • the inside thereof is provided with a metallic coating 222.
  • the cooling tubes 2 are advantageously fixed in the transverse webs 3 by means of pressing forces in that the groove flanks 320 are formed such that they represent a bottleneck for the flexible tubes 2. When the flexible pipes are inserted into the grooves 32, the fixing press forces are obtained.
  • the tubes can have different diameters d, for example from the center of the heat transfer system 11 towards the side edge decreasing.
  • the pipe surface does not have to be smooth; it can be rough or be corrugated to create a better hold in the ice.
  • the Pipes can be designed so that they can be removed individually. In In this case, check valves are an advantage. Means can be in the pipes built into a leakage protection.
  • distributor 21 or collector 22 and return line 81, 82 arranged in the middle; the connection curved and to Side out (so that winding on the roll 5 is possible); Access and / or Return line 81, 82 with check valve and / or shut-off device.
  • the pipes 2 can be moved when laying (then fixation). Anchoring option also within the Start and jump area.
  • Form-fitting attachment types for example attachment by chains.
