Definitions

  • the invention relates to a feed unit for a drain cleaning machine, in particular a drum drain cleaning machine.
  • the invention also relates to a drain cleaning machine.
  • Pipe cleaning machines are used to clean pipelines, such as drain pipes.
  • a cleaning spiral is rotated, optionally with a cleaning tool mounted on the end, and inserted into the pipeline to be cleaned.
  • the rotational movement of the cleaning spiral is usually generated by means of a motor, for example by means of an electric motor.
  • drum drain cleaning machines the rotational movement of the cleaning spiral is generated by a non-rotatable connection between the cleaning spiral and a rotatingly driven drum on which the cleaning spiral is kept wound up.
  • the drain cleaning machines usually have a feed unit, through which a drive of the cleaning spindle can be generated and adjusted.
  • clamping parts are usually used, which are pressed against the rotating cleaning spiral, thereby generating propulsion.
  • the propulsion can also be controlled by changing the position of the clamping parts in the pressed position against the rotating cleaning spiral.
  • the feed device is usually provided with a safety device.
  • the safety device reduces torsional stress that suddenly occurs in the cleaning spiral or prevents it from the outset, thereby avoiding a dangerous situation for the operator of the drain cleaning machine. Such sudden torsional stresses occur, for example, when the head of the cleaning spiral hits an obstacle to be cleaned, is braked sharply and the cleaning spiral itself is driven to rotate further.
  • drain cleaning machines are in the EP0894906A2 , US3882565A , EP1156167A2 , EP0443290A1 and NL9100342A released.
  • One embodiment of the invention is therefore based on the object of proposing at least one possibility by which simple operation and handling of a drain cleaning machine is made possible.
  • This object is achieved with a feed unit which has the features of claim 1. Furthermore, this object is achieved with a pipe cleaning machine having the features of claim 10.
  • a feed unit for a cleaning spiral, which can be rotated about its longitudinal axis by a motor, of a drain cleaning machine, for example a drum drain cleaning machine.
  • the cleaning spiral is a coiled, flexible shaft, which is also referred to as a cleaning snake or spring shaft.
  • the feed unit has a propulsion device that can be used to propel the cleaning spiral and has at least two clamping parts, of which at least one clamping part can be brought into a clamping position against the cleaning spiral in such a way that the clamping parts press against the cleaning spiral, so that the cleaning spiral is propelled when the cleaning spiral is rotating.
  • the feed unit also has a control device for controlling the advance of the cleaning spiral, for example the advance direction and/or the advance speed, by means of at least one of the clamping parts.
  • the feed unit has a safety device, through which at least one of the clamping parts can be brought out of its clamping position against the cleaning spiral.
  • control device and the propulsion device and/or the safety device can be actuated by a common handle part.
  • This measure allows the feed unit and thus a pipe cleaning machine with such a feed unit to be operated in a simple manner.
  • An operator only needs a single free hand to operate the feed unit. With such a one-handed operation, the operator has his other hand free, for example to guide the cleaning spiral and/or form a working arc from a length section of the cleaning spiral and thus exert pressure on a section of the cleaning spiral already located in the pipeline.
  • the handle part is coupled to the propulsion device, the at least one clamping part can be brought into the clamping position on the cleaning spiral by means of the handle part and thus the propulsion of the rotating cleaning spiral can be generated.
  • the safety device can be triggered or actuated by means of the handle part, for example by bringing the clamping parts or at least one of the clamping parts out of the clamping position against the cleaning spiral.
  • the propulsion of a rotating cleaning spiral can be controlled by the handle part, in that the control device is actuated by means of the handle part and thus, for example, forward propulsion or reverse propulsion of the rotating cleaning spiral is set. In principle, all functions of the feed unit can be carried out by operating the handle part.
  • the handle part is mounted rotatably about an axis and in Is mounted displaceably or pivotably in the direction of the axis, at least one of these types of movement being used to actuate the propulsion device and/or to trigger the safety device and another of these types of movement being used to actuate the control device.
  • the common handle part can be implemented in a technically simple manner in order to be able to actuate the control device and the propulsion device and/or the safety device.
  • the handle part can be pivoted about a pivot axis which is at a distance from the axis. This results in a favorable lever ratio with regard to the execution of a rotary movement of the handle part about that of the axis, in particular when the handle part extends with its longitudinal extension transversely to the axis during the rotary movement.
  • the feed unit is actuated in a technically simple manner if, according to a further embodiment of the invention, the propulsion device and the safety device can or act on at least one common clamping part, in particular on the at least one clamping part that can be brought into the clamping position against the cleaning spiral can or act .
  • the measure of a further embodiment of the invention aims in the same direction, according to which the propulsion device and/or the safety device together with the control device have at least one common tensioning part are effective or act, in particular on the at least one can be brought into the clamping position against the cleaning spiral clamping part are effective or act.
  • the propulsion device and the safety device can use a common mechanism in order to be able to establish the frictional connection between the clamping parts and the rotating cleaning spiral for generating the propulsion and also to be able to cancel the frictional connection again.
  • the handle part is designed as an actuating lever which is pivotably mounted on a control part in the direction of one or the setting axis for one of the clamping parts about a pivot axis.
  • a transmission element acting on one clamping part in the direction of the setting axis acts on the actuating lever, in particular at a distance from the pivot axis on the actuating lever.
  • the clamping part is displaced along the adjustment axis in order to reach the clamping position against the cleaning spiral.
  • the adjustment axis is arranged radially with respect to the cleaning spiral.
  • a pivoting movement and a rotary movement of the handle part designed as an actuating lever are used to operate the feed unit.
  • the physical requirements for actuating the propulsion device and the control device are taken into account in that the handle part and thus one clamping part is rotated to control the propulsion and to generate the jamming of the cleaning spiral between the clamping parts of the Actuating lever has to perform a pivoting movement. Due to the pivoting movement, the force of the lever arm of the actuating lever is utilized in order to exert the greatest possible compressive force on the cleaning spiral via the transmission element and one clamping part.
  • the transmission element should be dimensionally stable, in particular rigid.
  • the transmission element is formed by an eye bolt, the eye of which is rotatably mounted on the actuating lever.
  • control part to be rotatably mounted on a guide part which is fixed to the housing and which guides a clamping part during a movement in the direction of the pitch axis and/or during a rotary movement about the pitch axis.
  • guide part is a reliable and durable Operation or actuation of the handle part guaranteed.
  • the guide part is designed as a sleeve element or tubular element, on the outer circumference of which the control part is rotatably mounted and on the inner circumference of which the tensioning part is guided.
  • the guide part has a thread on its outer circumference, which interacts with a counter-thread of the control part in order to form the rotatable mounting of the control part relative to the guide part. In this way, the rotatable mounting of the control part on the guide part is implemented in a technically simple manner.
  • the actuating lever, the control part, the transmission element and one clamping part are connected in a rotationally fixed manner with respect to the setting axis and can be rotated about the setting axis relative to the guide part.
  • the transmission element serves to transmit the rotational movement of the actuating element to one clamping part about the setting axis.
  • the transmission element and one clamping part are connected in a non-displaceable manner with respect to the pitch axis and can be displaced relative to the control part and the guide part in the direction of the pitch axis.
  • power is transmitted to one clamping part in a structurally simple manner in the event that the actuating lever executes a pivoting movement.
  • an additional guide part can be provided, which is firmly connected to one clamping part and is guided on a wall of an opening of the guide part fixed to the housing and/or a wall of an opening of the control part.
  • the mechanism described above can only act on one of the clamping parts, by means of which the clamping part can be displaced in the direction of the pitch axis and can be rotated about the pitch axis. It can also be the case that the mechanism acts on several of the clamping parts, in particular on all clamping parts. For example, the mechanism only acts on one clamping part in order to bring about an adjustment movement in which one clamping part is displaced in the direction of the adjustment axis.
  • the other clamping parts may also be rotated, in particular a rotational movement about a radial axis, due to the coupling of the clamping parts to one another, for example via a common driver along the longitudinal axis of the cleaning spiral.
  • At least one spring element is provided, against the restoring force of which at least one of the clamping parts, in particular together with the handle part, can be brought into a starting position, either automatically or with the aid of manual force, in which the at least one clamping part is brought out of its clamping position against the cleaning spiral is and thus the clamping against the cleaning spiral is released.
  • the starting position can be a position in which the at least one tensioning part lies at a distance from the cleaning spiral.
  • the starting position can be a position in which the tensioning part is only brought out of its force application against the cleaning spiral, which is present in the tensioned position, in order to generate the propulsion.
  • the at least one clamping part or the clamping parts prefferably held in the starting position relative to one another by the force, in particular the prestressing force, of the spring element. This ensures that the at least one clamping part is already in the desired starting position when the drain cleaning machine is switched on. Overall, this results in a high degree of operational safety, since the at least one clamping part and optionally the handle part are in a predetermined position without actuation of the handle part.
  • the propulsion device, the control device and/or the safety device prefferably be arranged on a housing or support, with the housing or support having at least one coupling point for stationary coupling to a drain cleaning machine.
  • the feed unit can be mounted in a fixed position on the drain cleaning machine in a technically simple manner.
