Definitions

  • the invention is directed to a device for receiving a hose that can be unwound, in particular an exhaust gas suction hose, the downstream end of which is effectively led out of the drum axis of a winding drum and is connected to a vacuum source.
  • DE-PS 25 54 511 shows a hose drum in which the individual hose windings are arranged horizontally next to one another and the exhaust hose there is guided through the interior of the drum axis to a blower.
  • the known solution shows u.a. the possibility of driving the hose drum by an electric motor, i.e. perform the unwinding and winding up of such exhaust gas suction hoses by motor.
  • the unit is usually equipped with a cable, at the end of which a switch element to be operated by the user is provided, which controls the corresponding running of the drum via the electromotive drive.
  • blowers are switched on, which ensure the vacuum necessary for suction.
  • Systems with central suction are usually operated in such a way that the blowers permanently provide suction, regardless of whether the suction hose is used or not.
  • the blowers In compact systems with their own blowers per suction hose, the blowers must be operated via switches. In the case of motor-driven hose drums, these can also be put into operation or switched off at the corresponding actuation switches. In the case of mechanically driven hose drums, the blowers are switched separately.
  • the object of the invention is to provide a solution with which the handling of such exhaust gas suction hoses is simplified and, in particular, a kind of forced switching on of the blowers is achieved without the user of the exhaust gas extraction tube having to carry out additional manipulations.
  • this object is achieved according to the invention in that a rocker arm with a sliding and or rolling element is arranged /, wherein the sliding and / or roller element applies in the area of the upstream end of the coiled tubing to this and A of the tube b-wrap from a pressure switch operating in a pressure switch releasing position is movable.
  • This rocker arm switch causes the pressure switch to be released after a brief pull-out movement of the exhaust gas suction hose and the fan to be switched on by a corresponding circuit. It does not matter whether the drum is driven mechanically or by an electric motor. The first short pull-out movement of the hose is sufficient to actuate the switch and thus switch on the fan or fans.
  • hose windings are made in a helical single-layer arrangement or are arranged next to one another in horizontal windings on the hose drums described above in the prior art.
  • the invention provides that the hose reel is designed as a double disc with the exhaust hose spirally receiving lateral delimiting elements, the rocker arm with one over the outer surface of the hose rolling backup roller is equipped.
  • This type of winding which is known per se in other types of hose, such as fire hoses, offers particular advantages for the invention in the field of use of the exhaust gas suction hoses claimed here.
  • the rocker arm with the support roller which is supported on the outside, can be easily guided between the lateral limiting disks of the hose reel and can roll on the surface of the hose.
  • the design of the rocker arm and the switch actuated by it is thus particularly simple, maintenance-free and safe to carry out.
  • the rocker arm is equipped with the support roller with a stop element for fixing its end position.
  • the invention provides that the support roller engages in the fixed end position between the limiting disks of the drum and prevents a radial winding increase on the drum in this end position.
  • the rocker arm with the skid or the roller thus fulfills the double function of the switch actuation for the blower on the one hand and the braking means for the hose winding on the other hand.
  • the drum hub is designed as a worm with a lateral, axial outlet opening, and in a further development it can be provided that the lateral outlet opening of the hub worm opens directly into a flanged fan.
  • the hub screw can be designed, for example, as a cast part and thus assume a multiple function, once the conduction of the exhaust gases as such from the hose axially into a blower and the provision of the support surface for the hose to be wound up, the fastening means for the drum disks and the like.
  • the hub screw can be designed, for example, as a cast part and thus assume a multiple function, once the conduction of the exhaust gases as such from the hose axially into a blower and the provision of the support surface for the hose to be wound up, the fastening means for the drum disks and the like.
  • FIG. 1 Illustrated in Figures 1 and 2, generally indicated 1 apparatus used for receiving a developable Abgasabsaugschlauches 2 of which the windings are indicated in Fig. 1 only, while F ig. 2 shows on the left outside the upstream end with a plug-in nozzle 3 and the downstream end in the interior of a hose drum 4 which is flanged to a worm 5 which also forms the hub.
  • the hose drum 4 is formed in the example shown as a drum that winds the exhaust gas suction hose 2-spirally one above the other, laterally limited by a T drum disk 6 and 6 '.
  • the hose reel 4 is rotatably mounted on a frame 7 which extends substantially in a U-shaped manner, the simply reproduced frame 7 also carrying an exhaust fan 8 with an electric motor in the example shown 9 and an exhaust pipe 10, which can be attached in different installation positions.
  • the hub screw 5 not only forms the hub of the hose reel 4 from but at the same time also the deflection system for the exhaust gases is to bsauggebläse from the A bgasabsaugschlauch 2 through an axial opening 11 in the A to enter 8 and from there via the exhaust pipe 10, if necessary with the interposition of a filter, into the environment.
  • a rocking lever 12 which is also U-shaped in this case, is pivotably arranged on the frame 7, the U-legs being rotatably mounted on the frame 7 via axes 13, while the U-bridge is provided with a roller 14 is equipped, which is able to roll on the top of the exhaust gas suction hose 2.
  • Their position can be adjusted via a threaded spindle 15.
  • U-webs On the side of the swivel axis 13 opposite the U-leg, one of the U-webs presses a pressure switch 16.
  • the U-legs are also equipped with stops 17 which limit the end stop in the solid position shown in FIG. 2.
  • the drive of the hose reel can be carried out via a spring-loaded and not shown ratchet and detent system take place, which is indicated laterally in Fig. 1 and provided with the reference numeral 18, without the invention being limited thereto; instead of the spring assembly 18, an electric motor can be provided in the same way.
  • the mode of action is as follows:
  • the rolling element 14 initially rolls off the surface and is slowly broken due to the force of gravity as the radial packing density of the hose drum 4 decreases from the solid position into that in FIG. 2 reproduced position lowered.
  • the switch 16 is released in this lowering movement after a certain margin, so that it can trigger a switching operation.
  • the switching process of the switch 16 causes, for example, that the blower motor 9 starts up and thus the suction of gaseous media through the hose 2 via the hub element 5 into the blower 8 and from there via the exhaust pipe 10 to further elements, not shown.
  • the pivoting of the pivot lever 12 is the other way around, ie the hose 2 is wound up so far that it is in contact with the roller 14 tion is pivoted these gradually in the further A ufwickeliolo the pivot lever 12 from the dashed reproduced position to the solid position and thus operates the switch 16 in the reverse manner, so that for example the fan 9 is turned off.
  • the swivel lever 12 with the roller 14 performs two functions, namely a switching function for the blower 8 and a braking function for the exhaust gas suction hose 2.
  • the hub part 5 can also be formed by pipe elbows which allow the rotary movement, instead of a pure, multilayered winding of the exhaust gas hose, a horizontal side-by-side winding can also be provided and / or the combination of these two winding options.
  • the extension of the rocker arm can be used as a pure braking element 12 beyond the axis of rotation 13 can be dispensed with, the decisive factor is then only the stop 17 u.
