Definitions

  • the present invention relates to a hydraulic working device for portable use according to the preamble of claim 1, 10 and 20.
  • Hydraulic work tools for portable use are commonly used by the fire department for rescue operations. They have an electrically operated hydraulic pump, a rechargeable battery in the unit and swiveling tool halves. These are mainly used for cutting body parts and for spreading or blowing open vehicle doors. Such devices can also be used in disaster response z. B. in the recovery of buried people are used. However, these devices often have a high weight and relatively large dimensions, so that they are often unsuitable for mobile universal use. In addition, the applications of such devices are limited due to the nature of the tool halves used.
  • a working device is known from the data sheet SC 357 E2 LUKAS Hydraulik GmbH.
  • This known implement represents a rescue device with cutting and spreading function and comprises two tool halves, which have a toothed cutting contour and form a triangular spreading contour on the front side. The cutting contour ends at the expanding jaw.
  • a hydraulic unit and hydraulic circuit is known. This hydraulic unit is operated by means of a manual pump unit.
  • a compensation device in the form of a membrane and the hydraulic tank are in the extension of the cylinder housing.
  • a working device in the form of a hydraulic spreader for injured cars which has a hydraulic cylinder, a pump and a rechargeable battery.
  • the hydraulic tank and the balancer are arranged around the hydraulic cylinder.
  • the object of the present invention is to provide a generic working device, which allows an extended work area.
  • each mold half has a wall-shaped section extending perpendicular to the extension of the longitudinal axis of the piston rod and both sections together form a common flattened end region extending perpendicularly to the extension of the longitudinal axis of the piston rod in the closed state of the two tool halves, it is possible to do so Working device advantageously to use for spreading of Haustoder Hausmaschinenspalten.
  • the implement according to the invention with the specially designed tool thus allows a very fast access in apartments or houses.
  • the flattened end region is laterally offset from the extension of the longitudinal axis of the piston rod.
  • the flattened end region can be introduced without difficulty into a door gap, for example when the door gap is in the immediate vicinity of a door frame.
  • the flattened end region can be oriented obliquely to extend the longitudinal axis of the piston rod. As a result, the flattened end region can be introduced in unfavorable space easier in a door gap.
  • a tool half comprises a wall portion which is angled to the plane of the flattened end portion and intersects the center line of the extension of the piston rod. This wall area supports the opening movement of the door or the window.
  • the tip of the flattened end region has a bevel.
  • the bevel facilitates a turning of the flattened end region into a narrow door gap. Due to the fact that the tool halves are arranged to engage or overlap one another in the region of the flattened end region, on the one hand a particularly narrow, flattened front region can be achieved, since the tool halves do not "double up" in this region Tool half still be applied a sufficient force on the door gap.
  • the tool according to the invention advantageously has at least one planar, anvil-like wall section at its end opposite the end region.
  • This wall section serves as a stop surface to actively drive the flattened end region of the tool, for example with an ax or a hammer, into the door gap.
  • This can be very beneficial should the gap be too small to penetrate the flattened face area. By applying an external force a rapid penetration into the door gap is still possible.
  • At least one of the planar wall sections has a contour.
  • a crowbar can be attached to this contour so that it can be hit with a hammer or an ax on the inserted crowbar.
  • the contour has the advantage that the crowbar does not slip off the wall section with force by means of a hammer or an ax.
  • a contour can also be provided a knurl.
  • a further advantageous embodiment of the implement is characterized in that the tool halves additionally have a cutting contour. By this cutting contour, for example, attached to the door safety chain can be cut quickly after the door has broken.
  • the above object is achieved in particular by a hydraulic working device with the, also claimed in juxtaposed, features of claim 10.
  • the tool halves are spread over wide attachable tool halves. This allows a particularly fast replacement of the tools in use.
  • the previously described door opener tool can be designed such that it can be plugged onto these other mold halves.
  • Both tool halves namely, those that are plugged on, as well as those that are plugged on) each have a tool function, for example, a tool function squeezing, spreading, cutting or the like.
  • a coupling is expediently provided for attaching and removing the first mold halves of the second tool halves, which comprises a locking element which can be locked or unlocked with a large-area, plate-shaped actuating element.
  • the actuator can also be operated with thick gloves and thus ensures a rapid tool change.
  • the locking element is loaded with a spring and, when the first tool half is pushed onto the second tool half, engages in a bore on the second tool half.
  • the spring holds the locking element after attaching the first tool half to the second mold half in position. This ensures that the tool halves are not separated from each other in the labor input. By actuating the actuating element, the tool halves can be quickly separated or withdrawn from each other.
  • the actuating element has a preferably annular projection which is arranged opposite a corresponding bore. Upon actuation of the actuating element, the projection is pushed into the bore and the locking element located there is sunk in the bore. This allows trouble-free operation. It is advantageous that there is a beveled edge at the beginning of the second mold half. The chamfered edge causes when attaching the second tool halves on the first tool halves that the locking element is sunk against the force of the spring in the bore. The locking element then remains in this bore until the second tool half has been pushed so far into the first mold half, that the locking element has reached the located in the coupling bore. The locking element is pushed up by the force of the spring, whereby the tool halves are locked.
  • the mold halves serving as a receptacle have a preferably serrated cutting contour.
  • the attached tool halves also have a, preferably rectilinear, cutting contour. This is particularly advantageous, for example, when a cable and / or a safety chain is to cut through doors.
  • the cutting contour of the second, attached tool halves extends the cutting contour of the first tool halves forward.
  • the attached tool halves form a conventional triangular spreading contour.
  • the attached tool half has an inner contact surface and the cutting contour projects beyond the plane of the contact surface. This ensures that the operator does not have to search for the cutting contour, but that it is already in the top of the Tool half is located.
  • the inner contact surface offers the additional possibility of a squeezing function.
  • the cutting contour extends into the tip of the second tool half, so that e.g. a cable without an alignment of the tip of the implement can be cut quickly without loss of time.
  • Another expedient, also claimed as a secondary, embodiment of the working device is that the compensating device and the hydraulic tank are integrated together in the pump housing. This guarantees a particularly space-saving and weight-reducing design of the implement.
  • the pump housing has a lid which, together with the pump housing, forms a space in which the compensation device, for example in the form of a rubber membrane, is located and can extend into this space depending on the work situation.
  • This embodiment is structurally particularly simple. Appropriately, there is a holder for a lighting unit on the pump housing. This is useful when using the implement in complete darkness, z. B. by a SEK or in poor visibility. Thus, the operator can be guaranteed at least a certain illumination of the work area.
  • the lighting unit has its own power supply.
  • the separation of the power supply has the advantage that the battery for the pump can not be used by the lighting unit.
