Definitions

  • the invention relates to a fastening device for fascine mattresses.
  • Fascine mattresses are sunk by fastening them by one end to the sinking beam of a sinking device.
  • a rather complicated mechanical device with which problems sometimes occur during the detachment of the sunk fascine mattress.
  • the fastening in the case of the devices used is very complicated and time-consuming.
  • the object of the invention is to produce a device which does not have the above-mentioned disadvantages, and this object is achieved according to the invention in that the device is firmly fastened to a carrier and comprises two fixed parallel walls lying opposite each other at a distance from each other, and having a length which is essentially equal to the width of the mattresses, while provided between the fixed walls is an inflatable and deflatable flexible oblong element, with a maximum dimension in the transverse direction between the fixed walls, when the element is inflated and unsupported, which is greater than the distance between the walls, said oblong element being provided with means for the admission of compressed air thereto from a compressed, air source and the discharge of compressed air therefrom, as desired.
  • the device shown in the figures comprises two parallel, hollow flotation pipes 1 end 2, having a length which is approximately equal to the width of mattresses to be sunk.
  • the pipes are attached to each other by means of a number of vertical cross plates 4 which are fitted along the length of the pipes at regular intervals from each other, and which are welded by their end edges to the periphery of the pipes 1 and 2.
  • Extending over the full length of the device at the top of the plates 4 is a device for clamping an end edge part 6 of a mattress, said device being indicated as a whole by the reference number 5.
  • the clamping device is made up of a rectangular tubular section, extending in the lengthwise direction of the device and firmly welded to a top flange 8 and a reinforcement flange 9 of the plates, and some distance away from it an I-beam 10, whose body 11 runs parallel to a side 12 of the tubular section 7 facing it.
  • the I-beam 10 is firmly welded with its flanges 13 and 14 to the top flanges 15 and reinforcement flanges 16 respectively of the plates 4, while the body 11 is also firmly welded to the supporting I-beam 17.
  • an inflatable hose 18 Disposed between the body 11 of the I-beam 10 and the opposite side face 12 of the tubular section 7 is an inflatable hose 18, which can be connected by means of a valve (not shown) with a compressed air source, and which is also provided with means which are known per se for deflation thereof as desired.
  • the source of compressed air can be one or two hollow pipes 1 and/or 2, which to that end is or are provided, on the one hand, with means for filling thereof with compressed air and, on the other, with means for the discharge of compressed air therefrom to the hose 18.
  • the distance between the body 11 of the I-beam 10 and the opposite side face 12 of the tubular section 7 is smaller than the maximum diameter crosswise of the hose 18 vhen inflated and unsupported.
  • the side face 12 is provided with a strip 12' of material with a surface with increased friction resistance, such as rubber, which may be provided with grooves and corrugations if necessary.
  • the hose 18 is deflated, following which the end edge part can easily be pulled away.
  • the device shown can be fastened to a sinking beam of a sinking device and to that end is provided with a plate 20, which extends over the length of the device and on which a tubular sinking beam can come to rest, to which beam the device according to the invention can be fastened, the latter being provided for the purpose with fastening lugs 21 and 22 for fastening of straps round the pipe.
  • the device can also serve itself as a sinking beam and to that end is provided with means for fastening to a sinking device which is known per se..
  • the flotation device with the clamping device according to the invention fastened to it can also be used as a device for transporting Mattresses from a production point or the sinking device located there.
  • the device discussed can also be used to hold fast the end of mattresses lying opposite the end connected to the sinking device during sinking thereof.
  • a particular advantage of the fastening device described is that it works without reciprocating moving parts, which means that the device suffers little or no adverse effects from material falling on it or from the corrosive environment in which the device is used.
