Definitions

  • the invention relates to a pipe and sewer cleaning machine with a rotatably mounted jaw system for clamping fixing a drivable by the pipe and sewer cleaning cleaning spiral, the jaw system during the cleaning operation of the pipe and sewer cleaning machine by a motor drive device of the pipe and sewer cleaning machine into a rotary motion wherein the jaw system can be actuated by a hand lever of the pipe and sewer cleaning machine, wherein the cleaning spiral is clamped in the jaw system when the hand lever is actuated thereby causing the cleaning spiral to rotate, the pipe and sewer cleaning machine a with the hand lever operatively connected and deactivatable by an actuation of the hand lever safety device, wherein the safety device comprises a first electrical switch, wherein the first electrical switch is engageable with the hand lever to actuate the first electrical switch and disable the safety device, the jaw system is activated with the safety device in an idle state and the cleaning operation of the pipe and sewer cleaning machine is interrupted, the jaw system when activated Safety device in the rotational movement is added and the cleaning operation of the pipe and sewer cleaning machine
  • Such pipe and sewer cleaning machines are used, inter alia, for the elimination of contamination in piping systems.
  • a usually several meters long cleaning spiral is arranged in the pipe and sewer cleaning machine that the cleaning coil is guided through an axial opening of the jaw system, wherein clamping jaws of the jaw system along a circumference of the opening are arranged to be displaced in the radial direction.
  • the jaw system is rotatably mounted on a housing of the pipe and sewer cleaning machine. Once the motor drive device, usually by the operation of a manual switch, is put into operation, the jaw system is rotated by the drive means in the rotational movement, wherein the jaw system rotates with unconfirmed hand lever to the arranged in the opening of the jaw cleaning coil.
  • the cleaning coil can be displaced in the axial direction and introduced in this way in the pipeline to be cleaned and be displaced within the pipeline to be solved pollution.
  • the cleaning spiral is activated by an operation of the hand lever clamped fixed to the rotating jaw system and thereby set in a rotational movement through which the soiling can be easily opened and removed.
  • the jaw system is operatively connected via a lever mechanism with the hand lever, so that the jaws of the jaw system displaced radially upon actuation of the hand lever in the direction of the opening of the jaw system and pressed against the arranged inside the opening cleaning spiral.
  • the hand lever is usually designed spring-loaded, so that an actuation of the hand lever takes place against a spring force. Once the hand lever is no longer actuated, the hand lever is displaced by the spring force to the starting position, so that a clamping of the cleaning spiral is canceled.
  • end of the cleaning coil is usually arranged on the pipe to be cleaned and the assumed contamination adapted tool prior to insertion into the pipeline. If a replacement of this tool is required during the cleaning of a pipe, the pipe cleaning spiral is pulled out of the pipeline with the hand lever unoperated, so that the tool can be removed from the end of the cleaning spiral disposed in the pipeline during cleaning and replaced by an alternative tool ,
  • the jaw system rotates permanently, wherein the jaw system rotates around the cleaning spiral with unconfirmed hand lever around and, when the hand lever is actuated, causes the cleaning spiral to rotate as it were.
  • the cleaning coil is partially against an inner circumference of the opening of the jaw system and is offset by occurring between the jaw system and the pipe cleaning spiral on a contact surface friction forces in an undesirable rotational movement.
  • this undesirable rotational movement is avoided by holding the cleaning spiral by an operator of the pipe and sewer cleaning machine. Due to the frictional forces then occurring in the contact area, increased wear of the jaw system and the cleaning spiral can be observed.
  • EP 0 607 612 A and NL 9 100 342 A are described differently designed pipe cleaning machines.
  • EP 0 607 612 A a pipe cleaning machine described in which the jaw system is set in response to a pivot angle of the hand lever in the rotational movement.
  • an additional actuator is arranged, which is in operative connection with the safety device, wherein the safety device is deactivated when the hand lever is actuated and during the duration of a cleaning operation enabling operation of the hand lever with the Safety device operatively connected actuator was actuated at least once, wherein the safety device comprises a second electrical switch, wherein the second electrical switch is electrically connected to the first electrical switch and the actuating device, wherein the second electrical switch produces the electrical power supply when the first electrical switch is actuated and the actuating device has been actuated at least once upon actuation of the hand lever.
  • the hand lever is unintentionally actuated and the cleaning spiral is thereby placed in a particularly fast rotational movement, which is arranged at a arranged outside of the pipe to be cleaned end of the cleaning spiral or arranged at the end of the tool a particularly strong, beating rotational movement of the end or the tool and thereby leads to a particularly high risk of arranged in the vicinity of the pipe and sewer cleaning machine objects and in the field of the machine resident persons.
  • Such unwanted operation of the hand lever can be caused, for example, by the fact that the operator of the pipe and sewer cleaning machine crashes, thereby actuating the hand lever. If the operator, for example, injured and unable to act on the hand lever comes to rest, the hand lever is permanently activated and an extreme endangerment of objects and people unavoidable.
  • the jaw system is only set in a rotational movement when the actuator and the hand lever were operated.
  • the actuating device may advantageously be one at one of Pipe and sewer cleaning machine opposite end of the hand lever arranged knob act, this button is additionally advantageously at least partially disposed within the hand lever, so that accidental operation of the hand lever and the actuator is virtually excluded.
  • the actuating device can also be arranged, for example, on a side of the hand lever facing the pipe and sewer cleaning machine, preferably in an area adjoining the opposite end.
  • Such an embodiment of the pipe and sewer cleaning machine according to the invention is particularly advantageous when using an electric motor as a drive device, since in this case the required control of the electric motor by the safety device can be achieved particularly easily.
  • the second electrical switch may advantageously be a relay, a contactor or the like.
  • the safety device can have a coupling device that can be actuated by the hand lever, by means of which a force transmission between the drive device and the clamping jaw system can be established and separated again.
  • a coupling device is advantageous, inter alia, when the drive device used is an internal combustion engine, since the internal combustion engine is advantageously permanently in operation and is operated when the hand lever is not in an idling state and when the hand lever is actuated Driving force on the jaw system and the cleaning spiral transmits.
  • the operation of the drive device is interrupted when the hand lever is unactuated and thus activated safety device.
  • the drive means is an electric motor.
  • the operation of an electric motor can be easily recorded and interrupted.
  • the electric motor may be any commercially available rotating electric motor such as a DC motor, an AC motor and a synchronous or asynchronous machine.
