Definitions

  • the invention relates to an emergency braking device for funds in shaft systems according to the preamble of the claim.
  • an emergency braking device for funds in shaft systems on open passageways which works with rigidly arranged strips of variable thickness, on which brake sets are slidably attached, to which the funding strikes on the free passage.
  • the strips are made of wood and each brake set has a U-shaped and longitudinally wedge-shaped brake shoe, which is provided on the inside of the legs with knives that extend over the length of the brake shoe and which serve to tighten the brake shoe on the front side the bar have a slight inclination with respect to the vertical.
  • the conveyor hits the brake shoes on the free passage, they are moved along the wooden strips, which results in a braking force.
  • friction elements in the form of shoes are fastened to the conveying means, which interact with stationary brake sets.
  • These brake sets are designed as a steel structure, within which elastic elements are attached that act on the friction surfaces. If the conveying means enters the freely passable passage, the shoes penetrate into the brake sets and come into contact with the friction surfaces acted upon by the elastic elements.
  • the chamfer on the upper end of the shoes serves as an insertion aid when penetrating.
  • the shoes have surfaces parallel to one another below the insertion aid, so that only a constant compressive force is generated to generate the frictional force over the entire length of the shoes.
  • Emergency braking devices are also known in which the braking force is generated by pulling a steel rod through a calibrated opening of a guide eye or by stretching a steel rod with high elasticity.
  • the object of the present invention is therefore to develop an emergency braking device of the type described in the introduction in such a way that, with a simple technical structure and small mass, it reliably brakes conveying means, such as, for. B. vessels or the like. With large. load capacity at high speed.
  • the friction elements are designed as elongated and fixed at its lower end, tensile friction strips that extend in the conveying direction and their strength increases in the braking direction, and that the brake sets can be moved in a compact design on the friction strips are guided and arranged in the path of movement of the shaft conveyor in such a way that they are carried along by the shaft conveyor for overriding or underdriving for non-destructive displacement relative to the friction strips.
  • An emergency braking device can be used repeatedly because its parts are not destroyed during a braking operation. Accordingly, the time to resume operation is comparatively short, and there is practically no cost.
  • the construction of the device according to the invention - viewed over the entire length of the braking distance - enables the dimensioning of a braking force.
  • the emergency braking device consists of friction strips 2 rigidly attached to the conveyor frame 1, with increasing strength in the braking direction, which carry brake sets 3, which are designed as a steel structure 4 and which are displaceably guided on the friction strips.
  • Elastic elements 5 are accommodated within the steel structure 4.
  • the shaft conveyor 6 strikes a projection of the steel structure 4 when exaggerated, as a result of which the steel structure 4 is displaced with respect to the friction bars 2. Such a displacement leads to an elastic deformation of the elements 5, whereby frictional forces arise which the conveying means 6 brake.
