Definitions

  • the invention relates to a shaft conveyor system with a conveyor and an overdrive braking device for the conveyor, a longitudinally extending track for the conveyor and an overdrive adjoining a lower and / or upper end of the track.
  • a safety device which acts directly on the control of the hoisting machine, ensures that the hoisting machine is stopped.
  • the hoisting machine is then switched off by the limit switch and braked by the safety brake.
  • a mechanical device must greatly reduce the speed of the conveying means for safety reasons. If the conveyor goes underneath the bumper beam without braking, this can have serious consequences and even break the rope. Even at a low speed of a conveyor, it can have serious consequences for those driving on it if the conveyor drives unchecked under the bumper.
  • the overdrive braking device also referred to as an overdrive protection, reduces the consequences of exaggeration.
  • the overdrive braking device is located at the end of the shaft guide and has a device for braking that decelerates the conveying means.
  • the braking effect may only start above the upper stop of the conveyor and after the limit switch has been passed. For safety reasons, the maximum delay of the conveyor should not exceed the value of 9.81 m / s 2 .
  • braking devices In the case of shaft conveyor systems with guide rails, thickened or mutually inclined guide rails are used as braking devices.
  • the widened or contracted track battens are usually made of wood.
  • the braking devices In systems with rail guidance, the braking devices can also be made of steel.
  • the guide rod thickening is carried out in such a way that the guide rods are widened above and below the outermost operating position of the conveying means. This widening is carried out symmetrically on each side of the guide rails. If a conveying means is driven into the thickening of the guide staff, this is damaged by the guide shoes arranged on the conveying means. Braking with thickened guide rails is uncontrolled and often leads to the destruction of the conveyor.
  • an overdrive braking device from SIEMAG TECBERG in which a braking frame with roller boxes is forcibly guided on flat belts during braking. The plastic deformation of the brake bands in the roller boxes slows down the conveying means that hit the brake frame.
  • the overdrive decelerator can be installed at either end of the driveway and in both conveyor strands. The dimensions of the Flat belts are selected to match the shaft conveyor system, depending on the forces that occur.
  • the structure of the overdrive braking device from SIEMAG TECBERG can be found in its brochure "Technical Information Safety Braking Devices (SSA)", published at www.siemag-tecberg.com on 06/01/2016 and the DE 10 2013 001 405 A1 , Paragraph [0040].
  • a shaft hoisting system with a conveyor and an overdrive braking device for the conveyor with a longitudinally extending track for the conveyor as well as an overdrive path connected to a lower and / or upper end of the driveway, referred to there as an overdrive or underdrive zone, known.
  • brake booms are provided that are attached to the shaft or scaffolding support or to an auxiliary structure.
  • Braking means for example cutting tools, are arranged on the conveying means and, when the conveying means is overdriven, come into engagement with the braking beams made of any building material.
  • the GB 1 561 509 A discloses a shaft conveyor system comprising a shaft and a basket which can be moved in the vertical direction in the shaft.
  • a cutting edge is attached to the underside of the basket. When the basket crashes, it is slowed down by dipping the cutting edge into a column of energy-absorbing material, the column in a guide is arranged.
  • the energy-absorbing material is a reinforced plastic material.
  • Holding elements designed as holding strips are fastened in pairs and spaced apart on the overdriving path or on the conveying means.
  • Energy-absorbing material in the form of plates is arranged between the retaining strips.
  • a plow protruding into the space between the holding strips is arranged to be movable in the longitudinal direction relative to the holding strips. The retaining strips prevent the energy-absorbing material from buckling when it hits the plow.
  • the introduction of force by the plow takes place in a targeted manner on the energy-absorbing material which is fixed by the retaining strips and which is deformed and / or destroyed during the linear relative movement between the plow and the retaining strips along the braking distance. If the braking process is based on a deformation of the energy-absorbing material, it is about a plastic deformation, to avoid elastic forces counteracting the braking force.
  • the material properties of the energy-absorbing material are matched to the driving speed and the weight of the conveying means including the weight of the rope.
  • the energy-absorbing material is arranged in the form of plates one above the other between the holding elements designed as holding strips.
  • the plates can be arranged individually or in the form of several stacks of plates one above the other.
  • the retaining strips preferably encompass the edges of the longitudinal, i. Plates or stacks of plates arranged one above the other between the retaining strips in the direction of the braking distance. If the conveying means accidentally enters the overdrive braking device only over a part of the braking distance, only the plates destroyed by the plow need to be replaced.
  • Either the plow is movable and the retaining strips are arranged in a stationary manner on the overdriving path or the plow is arranged in a stationary manner on the overdriving path and the holding strips are movably arranged.
  • the plow can be arranged directly on the conveying means.
  • the plow can be arranged on a movable brake frame which is positively guided in the longitudinal direction of the overdrive path.
  • the brake frame is guided in particular in a guide frame of the shaft conveyor system.
  • the brake frame has stop surfaces on which the excessive conveying means strikes and thereby transfers the kinetic energy to the brake frame and the plow arranged thereon.
  • the plow is indirectly linked to the conveyor.
  • the retaining strips are stationary, preferably displaced on the guide frame.
  • the plow can be shifted directly on the guide frame.
  • the retaining strips are relocated to the movable conveyor.
  • fiber composite materials are preferably used as energy-absorbing material, which comprise a bedding matrix made of plastic and reinforcing fibers.
  • the fibers give the material its high mechanical stability, while the matrix absorbs the forces exerted by the plow and distributes them in the structure.
  • the fibers can consist of inorganic and / or organic and / or metallic material.
  • the guide frame of the overdrive braking device must be designed in such a way that the conveying means can move freely along the intended braking distance when overdriven.
  • the guide frame has several, for example four vertical support beams as well as an upper and a lower displacement, each of which consists of several, for example four, transverse beams arranged between the support beams.
  • Opposite front sides and opposite long sides delimit a cuboid guide frame with four vertical support beams.
  • the width of the longitudinal sides of the guide frame is greater than the width of the longitudinal sides of the conveyor.
  • the width of the end faces of the guide frame is greater than the width of the end faces of the conveyor.
  • the conveying means is usually designed as a conveyor cage and consists of a stable steel profile frame with mostly several levels.
  • the front sides of the conveyor cage are open, while the side walls are covered with metal sheets, in particular perforated sheets.
  • the front entrances are closed with a door for passenger transport.
  • the retaining strips with the energy-absorbing material arranged in between are preferably arranged parallel to the side walls of the conveyor cage on the guide frame or directly on the conveyor so as not to hinder access to the end faces of the conveyor cage.
  • At least one pair of retaining strips are attached to the lower and upper displacements on opposite sides of the guide frame and extend parallel to the support beams between the displacements.
  • the pairs of retaining strips are preferably attached centrally to the displacements.
  • At least one guide profile is attached to the lower and upper offset on opposite sides of the guide frame and extends parallel to the support beams, with guide shoes arranged on the brake frame encompassing the guide profiles.
  • overdrive braking device If the overdrive braking device is located at the upper stop of the conveying path, supports arranged on the lower displacement bear the load of the brake frame that can be moved in the direction of the braking path. However, if the overdrive braking device is arranged in the shaft sump, the Load of the brake frame on the plow can be absorbed by the plates made of energy-absorbing material.
  • the guide profiles of the brake frame are preferably arranged parallel to the end faces of the conveying means.
