Description

AREA

[0001] The present subject matter relates generally to a drain cleaning device. In particular, the present subject matter relates to a drain cleaning device which includes a holder for the removable securing of a drum and a feed device to a frame of the drain cleaning device. BACKGROUND

[0002] Drain cleaning devices typically include a rotating drum attached to a frame. A cable is wound inside the drum and fed from the front, leading into a drain or sewer pipe to clean it of debris that has accumulated there. Drain cleaning devices often include a cable feeder attached to the frame, which moves the cable in and out of the drum and into and out of the drain pipe. The drum, feeder, and other components are secured to the frame by mechanical fasteners.

[0003] In operation, cables of varying lengths can be used depending on the size of the drain pipe and its accessibility. If the entire length of cable has been dispensed from the drum during final cleaning, or if the cable breaks or is damaged, it may be necessary to remove the first drum and install a second drum with a different cable on the device. Replacing the first drum can involve several steps: loosening and removing the first drum and then attaching a second drum to the device. These steps may require other equipment, such as the feed unit, to also be disconnected from the device to access and remove the first drum.

[0004] For example, replacing a drum on a drain cleaning device that has a cable feed mechanism often involves numerous steps, beginning with removing the feed mechanism from the device's frame. This process may involve unscrewing mechanical fasteners that hold the feed mechanism to the frame and then removing the feed mechanism from the frame. Next, by unscrewing mechanical fasteners that hold a locking mechanism securing the drum to the frame, the lock is removed, and then the first drum is removed. Furthermore, these numerous steps must be performed in reverse order to install the second drum on the device.These numerous steps can be time-consuming and tedious, causing delays at the workplace and thus incurring additional labor costs. Furthermore, separate tools (such as screwdrivers, pliers, socket sets, or drills) are required to unscrew the mechanical fasteners that hold the feed mechanism to the frame and secure the locking mechanism.

[0005] Accordingly, there is a need for a simpler, easier and less time-consuming way to replace a drum in a drain cleaning device. SUMMARY

[0006] The difficulties and disadvantages associated with previous approaches are addressed in the present document as follows.

The base is designed for connecting the bracket to the frame of the drain cleaning device. The base includes first and second holes. The locking mechanism is rotatably attached to the base and is movable between an open and a closed position. The first and second holes are designed to receive mounting pins for the feed unit, enabling the feed unit to be attached to the base. When the locking mechanism is in the closed position, a gap is provided between the locking mechanism and the base to accommodate a drum bearing for securing the drum.

[0008] In another aspect, the present article provides a bracket for the removable securing of a drum bearing and a feed device to the frame of a drain cleaning device. The bracket includes a base for connecting the bracket to the frame of the drain cleaning device.

The chamber contains a hinge that pivotally connects the locking mechanism to the base.

[0009] In yet another aspect, the present article provides a drain cleaning device comprising a frame, a bracket, a drum, and a feed mechanism. The bracket includes a base, a locking mechanism, and a hinge that pivotally connects the locking mechanism to the base. The base is mounted on the frame and includes first and second holes and a first piston pin that is movable between a first position, in which the first piston pin engages the first hole, and a second position, in which the first piston pin does not engage the first hole. The locking mechanism is pivotally attached to the base and is movable between an open position and a closed position.The locking mechanism includes a second piston pin that is movable between a first orientation, in which the second piston pin engages the second hole when the locking mechanism is in the closed position, and a second orientation, in which the second piston pin does not engage the second hole when the locking mechanism is in the closed position. The drum is rotatably and removablely secured to the bracket and is rotatable about a pivot axis. The drum includes a drum bearing. The feed device is removablely secured to the bracket and, when actuated, moves a cable axially inward or outward with respect to the drum. The feed device includes a first and a second securing pin. The drum is removablely secured to the bracket when the drum bearing is located between the base and the locking mechanism and the locking mechanism is secured in the closed position.The feed device is removable and secured to the bracket when the first fixing pin is fully inserted into the first hole, the second fixing pin is fully inserted into the second hole, the lock is in the closed position, the first piston pin is in the first position, and the second piston pin is in the first alignment.
