Abstract
A device for driving a flexible lance for cleaning a heat exchanger duct or the like, includes a frame in which a driving mechanism is arranged for moving this flexible lance in a driving direction in the direction of an outlet opening. The driving mechanism is provided with a clamp member which can be clamped on the flexible lance and which is movable in the frame towards and away from this outlet opening. The clamp member is mounted on an endless drive element. The active part of the endless drive runs parallel to the driving direction. The drive mechanism further comprises at least one non-driven counter roller arranged opposite said clamp member. The lance is clamped between the clamp member and the counter roller.
Claims19
A device for driving a flexible lance for cleaning a heat exchanger duct, comprising:
- a frame, a driving mechanism coupled to said frame, the driving mechanism configured for moving the flexible lance in a driving direction which is in a direction of an outlet opening,
- wherein the driving mechanism includes a clamp member which is clampable on the flexible lance and which is linearly movable in the frame towards and away from the outlet opening, wherein said clamp member is mounted on and moves with an endless drive element,
- wherein the endless drive element includes an active part that runs parallel to the driving direction,
- wherein the driving mechanism further comprises at least one non-driven counter roller arranged opposite said clamp member, and
- wherein the flexible lance is clampable between the clamp member and the non-driven counter roller.
A device for driving a flexible lance for cleaning a heat exchanger duct, comprising:
- a frame, a driving mechanism coupled to said frame, the driving mechanism configured for moving the flexible lance in a driving direction in the direction of an outlet opening,
- wherein the driving mechanism comprises a plurality of separate clamp members which are clampable on the flexible lance and which are linearly movable in the frame towards and away from the outlet opening,
- the device further comprising an endless drive element, wherein the clamp members are mounted on the endless drive element and arranged along the length thereof,
- wherein an active part of the endless drive element runs parallel to the driving direction,
- wherein the driving mechanism further comprises a second drive mechanism arranged opposite said clamp members,
- wherein the flexible lance is clampable between the clamp members and the second drive mechanism, and
- wherein the clamp members are arranged to pivotally connect to and move with the endless drive element.
