Definitions

  • Lift gates for closing door openings have a door leaf, Guide rails arranged to the side of the door opening for the door leaf with side rollers, and above the guide rails a drivable, with winding drums for traction devices for lifting and lowering the door leaf provided shaft.
  • the invention is based on such a lifting gate with the Task to make the lifting gate suitable for the conclusion a gate opening of a deep-freeze storage room.
  • This The task is solved by training the lift gate with the combination of features listed in claim 1.
  • the door leaf can be used when using a panel or of panel parts with vacuum insulation (claim 2) because their extremely high thermal insulation value, with very little Execute thickness (up to 1/15 conventional thickness).
  • the usage of belts as a traction device (claim 3) per se a higher winding speed compared to other traction devices to.
  • there is winding the belts lifting the door leaf and the accompanying Unwind the counter torque on the winding shaft introductory straps a change in gear ratio with a high initial moment, which together with the engine torque a high acceleration and so that the quick opening of the lifting gate results.
  • the counter moment can be exerted by the belts counterweights carried (claim 4) or the straps tensile Springs (claim 5), wherein the use of Counterweights especially for large and accordingly recommends heavy door leaves, whereas the use of Cushion the high initial acceleration due to their high Tension is further promoted when the door leaf is low.
  • the gas bark Lift gate consists of a door leaf 1, which its side edges with an upper roller 2 and a lower roller 3 is provided.
  • the top casters 2 is a guide rail 4r on the right-hand side and on the left-hand side a guide rail 41 and the lower rollers 3 is a guide rail 5r on the right side and on the left side assigned a guide rail 51. They are attached Guide rails 4r, 5r and 4l, 5l each on one out of one Square tube formed partially open post 6r or 6l.
  • a shaft 7 which is on the left in a gear housing 8 attached to the upper end of the post 6l to the right of one attached to the top of the post 6r Bearing 9 is rotatably supported. Is driven the shaft 7 from a motor 10. On the shaft 7 are non-rotatable two belt drums 11 and two belt drums 12 are arranged, of which the belt drums 11 for winding with the door leaf 1 connected belts 13 and the belt drums 12 for the opposite winding of counterweights 15 connected belts 14 are provided.
  • a design example for a lifting gate with an opening height of 3.20 m and a minimum opening height of 2.00 m is as follows:
  • the winding shaft 7 is of a tubular piece with an outer diameter formed by 160 mm with inserted journal, on the circular blank to delimit the winding drums 11, 11a and 12 are welded.
  • the straps 13, 13a and 14 have a thickness of 3 mm. With a basic winding results the base diameter of the winding drums is 166 mm.
  • the door leaf After four revolutions of the winding shaft 7, the door leaf is over 2236 mm raised, i.e. the minimum opening exceeded.
  • the belts 13 have a diameter of 169 mm and for the belts 14 a diameter of 199 mm effective, so that the acceleration process the door leaf 1 when opened with a force of 21.6% of the dead weight in addition to the engine torque is initiated.
  • the illustrations in the figures show the lifting gate in the closed position Condition in which the door leaf 1, which at its Lower edge is provided with a sealing bead 18, with this lies sealingly on the hallway 19, and with its side edges and its upper edge sealing to the side and placed above the gate opening 20 on the wall surface Sealing beads 21 and 22 are present.
  • the guide rails 4r, 4l, 5r and 5l on their lower End sections provided with kinks 23 over which the Door leaf 1 from the rollers 2 and 3 at the end of its lowering movement moved to the sealing beads 21 and 22 will, up to its abutment on the sealing beads, whereby at the same time the door leaf 1 with its sealing bead 18 comes to rest on the hallway 19.
  • sealing beads 18, 21 and 22 are provided with heating conductors 32 in their interior, whereby icing of the sealing beads 18, 21 and 22 excluded is.
  • the sealing bead 18 is also as Contact strip 32 with the contact strips 33p and 33n and one Seal lip 34 provided.
  • the one-piece panel forming door leaf 1 is (see Figures 3A and 3B) constructed from two stainless steel cover plates 35, which are welded airtight with a membrane frame 36.
  • the interior is with a support grid 37 made of insulation material filled out and via an evacuation connection a value less than 0.1 mbar can be evacuated.
  • the modification shown in Figure 1B to the embodiment 1A is that near the straps 13th are provided parallel to these seat belts 13a, which are connected to the door leaf like the belts 13 and which on the winding shaft 7 each have a winding drum 11a is.
  • the seat belts 13a are without tension the door leaf 1 and its rotationally fixed with the winding shaft 7 connected winding drums 11a, however, could the seat belts 13a even under slight pretension stand when the winding drums 11a rotatably to Winding shaft 7 via a limited torsionally flexible coupling would be connected to the winding drums 11.
  • FIG. 2C A further modification is shown in FIG. 2C and is that to apply a counter torque by the weight of the door leaf 1 via the straps 13 and the winding drum 11 applied torque a spring 38 is provided. This is from an eyelet 39 at the bottom End of the post 6 held and in a yoke piece 40 one loose roll 41 hooked in by a loop of a Belt 14a is worn, the belt 14a with its end strand at the upper end of the post 6 by a clamping plate 42 is held while the other strand of the belt 14a on the with the winding shaft 7 rotatably connected winding drum 12a is attached.
  • the springs 38 can be used instead of counterweights 15 or used together with one, in any case, the condition applies that a torque compensation is only given when the door leaf 1 a Has reached the minimum opening height.
